Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims benefit from currently pending U.S. Provisional Application No. 63/710,760 titled “Portable Tray with Attachment Clip” and having a filing date of Oct. 23, 2025, all of which is incorporated by reference herein.

FIELD OF THE INVENTION

The present technology is situated in the field of infant and toddler dining accessories, with particular emphasis on tray assemblies designed to address issues associated with existing tray designs, such as those utilizing suction for table attachment, by incorporating enhanced safety features, versatile attachment mechanisms, and effective spill management solutions

BACKGROUND OF THE INVENTION

The field of infant and toddler dining accessories encompasses a variety of designs aimed at creating a convenient and safe eating environment for young children. These products typically involve some form of tabletop attachment to prevent movement during use and reduce potential hazards associated with spillages or accidental disengagement.

Traditionally, these products use multiple suction cups as a mechanism as the primary means for securing trays to tables; however, suction cups exhibit significant limitations. Suction-based solutions often fail on uneven or porous surfaces, leading to instability, and may lose efficacy over time due to wear and exposure to contaminants. Suction cups can be challenging to clean adequately, which can lead to hygiene concerns over prolonged use. Additionally, children can pull up on the mat and easily remove the mat from the table due to the suction cup not adhering to the table and spilling everything all the table and floor. These drawbacks highlight the need for a more adaptable and reliable attachment mechanism that ensures stability across various dining environments without compromising cleanliness. Furthermore, existing designs often neglect to incorporate effective safety measures to protect infants from injuries due to the hard edges of tables.

Current solutions suffer additional drawbacks concerning material composition and adaptability to varied dining settings. Many food mats for infants are constructed from materials that are either not suitable for repeated cleaning or degrade with frequent use, posing hygiene issues. Additionally, numerous designs lack the ability to flexibly attach to surfaces of varying thicknesses, thereby limiting their usability in diverse environments such as restaurants or at home, where table dimensions differ independently of standard configurations. This limitation restricts parents and caregivers to a narrow range of applicable situations, reducing the practical utility of conventional trays.

The lack of comprehensive spill management features in existing products further highlights a critical gap in the effectiveness of current tray designs. Typical food tray assemblies do not provide adequate mechanisms to manage or contain liquid spills, leading to increased clean-up efforts and potential for mess-related hazards. Spill management features, such as integrated barriers or channels to divert liquids, are often insufficient or entirely absent, thereby failing to assist caregivers in maintaining a clean and safe dining area for toddlers.

What is needed is a solution that not only addresses the attachment limitations and safety concerns inherent in existing child tray mat designs but also enhances adaptability and spill management to suit various dining environments. Such a solution would provide a robust, adaptable attachment method able to secure trays to restaurants and household tables, while also incorporating features that mitigate safety hazards. Additionally, improved spill management capabilities would assist in maintaining a sanitary dining space, thus significantly enhancing ease of use for caregivers managing young children during meals

DETAILED DESCRIPTION OF THE INVENTION

In the following description, and for the purposes of explanation, numerous specific details are set forth to provide a thorough understanding of the various aspects of the invention. It will be understood, however, by those skilled in the relevant arts, that the present invention may be practiced without these specific details. In other instances, known structures and devices are shown or discussed more generally to avoid obscuring the invention. In many cases, a description of the operation is sufficient to enable one to implement the various forms of the invention, particularly when the operation is to be implemented in software. It should be noted that there are many different and alternative configurations, devices, and technologies to which the disclosed inventions may be applied. The full scope of the inventions is not limited to the examples that are described below.

Referring initially to FIG. 1-7 a portable tray with an attachment clip is shown generally at 10. The portable tray with an attachment clip 10 can be designed to be easily attached and detached from a table, providing a convenient and portable surface for various uses. The tray 10 can comprise a mat portion 12 with a top surface 14 and bottom surface 16, a thickness 22, and first end 20 and second end 18. The mat portion 12 serves as the primary surface upon which food, dishes, utensils, and other dining accessories are placed during use. The mat portion 12 can be dimensioned to provide adequate surface area for a child's meal while remaining compact enough for portability and convenient storage when not in use.

The mat portion 12 can be flexible substrate and can be made from such as, for example, thermoplastic rubber, silicone, polyurethane, polyvinyl chloride, or the like and can have a Durometer Shore of such as, for example, at least 10 to 100, and still more preferably 30 to 80 and more preferably 40. The mat portion can be safe for food contact and easy to clean. The top portion and/or bottom portion can be made from compression-molded liquid silicone or in other embodiments it can be such as, for example, injection mold silicone, thermoplastic elastomers, polyurethane, Ethylene-vinyl acetate, latex rubber, or the like. The mat portion 12 can be rolled, folded, or otherwise manipulated for storage and transport. The flexible nature of the mat portion 12 can allow caregivers to easily pack the tray in a diaper bag, purse, or other carrying container when traveling or dining away from home.

In embodiments, the mat portion 12 can further comprise a lip 15 configured as an extended flange, which can extend from the top surface 14 wherein the lip can surround the outside perimeter of the mat. The lip 15 can help to contain items placed on the tray and prevent them from sliding off. The lip 15 can be formed as a part of the top surface 14 or can be coupled to the top surface by such as, for example, adhesive, welding, hook and loops or the like. The lip 15 can be made from such as, for example, compression-molded liquid silicone, injection mold silicone, thermoplastic elastomers, polyurethane, Ethylene-vinyl acetate, latex rubber, or the like. In certain embodiments, the lip 15 can be omitted.

In certain embodiments, the lip 15 can have features that can enhance its spill containment performance beyond simply providing a vertical barrier. The inner surface of the lip 15 (the surface facing the interior of the mat) can be treated with a hydrophobic coating that causes liquids to bead up and flow away from the lip toward the center of the mat, reducing the likelihood that liquids will overflow the lip or seep under it. Alternatively, the inner surface can be treated with a hydrophilic coating that causes liquids to spread along the lip surface, increasing the effective containment volume before overflow occurs.

In other embodiments, the lip 15 can include drainage channels or weep holes positioned to allow controlled drainage of accumulated liquids when the mat is tilted for cleaning or emptying wherein the drainage can be positioned at corners or at the lowest point of the lip when the mat is in its typical cleaning orientation, allowing efficient removal of liquid waste without requiring the mat to be completely inverted. The drainage features can be sized to allow liquid flow while still preventing solid food items from passing through. In certain embodiments, the lip 15 can have variable height around the perimeter of the mat, with higher sections positioned where spill containment is most critical and lower sections where access or visibility is more important. The side of the mat closest to the child might have a lower lip height to improve the child's ability to see and reach items on the mat, while the opposite side might have a higher lip to provide maximum containment. In certain embodiments, the lip 15 can be omitted entirely, resulting in a flat mat configuration without raised edges. A flat mat design can be preferred for certain applications where maximum portability and minimal storage volume are prioritized, where the mat will be used on surfaces with their own containment features (such as a highchair tray with raised edges).

In embodiments, the portable tray with an attachment clip 10 can have a clip portion 30, which can comprise a spring 42 with a cover 36. The spring 42 can be over molded by the cover 36, wherein the cover can be made from such as, for example, compression-molded liquid silicone, injection mold silicone, thermoplastic elastomers, polyurethane, Ethylene-vinyl acetate, latex rubber, or the like and can be made from food-grade silicone. The over-molded construction can seal the spring 42 from exposure to food, liquids, and contaminants.

The clip portion 30 can have a straight section 34 coupled to the first end 20 and a radius section 36 substantially looping back to towards the bottom surface 16 with an open section 41. The straight section 34 of the spring 42 can partially overlap into the first end 20 of the mat portion 12 and can be integral with the mat portion's first end 20 or in certain embodiments the spring 42 can stop at the mat portion where the spring portion and the mat portion are coupled. In embodiments, the straight section 34 and the cover 36 of the clip portion 30 can provide a flush surface between the bottom surface 14 of the mat and the table, ensuring stability when the tray is in use. The cover 36 can be made of the same or similar material of the mat portion 12 and can be the substantially same thickness or varying thickness.

The clip portion 30 can have a straight section 34 and a radius section 36 which can create a C-shaped or hook-shaped profile. The straight section 34 can extend along the first end 20 of the mat portion 12, providing a rigid foundation that distributes clamping forces across a relatively large area of the mat. This distributed force application prevents the clip portion 30 from creating stress concentrations that could tear or deform the mat material at the attachment point. The radius section 36 can loop back toward the bottom surface 16 of the mat portion 12, creating the open section 41 that receives the table edge. The curved profile can allow the clip portion 30 to accommodate table edges with various radii and chamfers, from sharp square edges to heavily rounded bullnose profiles wherein the universal fit can allow the clip portion to fit on tables encountered in diverse environments such as restaurants, homes, outdoor dining areas, and institutional settings. The partial overlap of the straight section 34 of the spring 42 into the first end 20 of the mat portion 12 creates a reinforced transition zone where the flexible mat portion 12 connects to the spring-loaded clip portion 30.

In other embodiments, the spring 42 can stop at the mat portion and the components can be coupled together using adhesives formulated for compatibility with both the spring material and the mat material. Alternatively, the components can be welded using thermal or ultrasonic energy to create a molecular bond at the interface. In still other embodiments, the spring 42 and mat portion 12 can be mechanically interlocked using features molded into both components, such as tabs, slots, or dovetail joints that prevent separation. In yet another approach, the spring 42 can be captured within the over-molded cover 36 such that the cover material itself provides the coupling force by gripping both the spring and the mat portion simultaneously.

In embodiments, the spring 42 can ensures the clip portion 30 maintains a secure attachment to the table. The spring 42 can allow the clip portion 30 to flex and exert a constant pressure, allowing it to grip firmly and adapt to various table thicknesses without allowing the clip portion to slip off the table. The spring 42 can be such as, for example, leaf spring, torsion spring, compression spring, coil spring, cantilever spring, or the like. The spring 42 can vary in k-factor or strength of the spring depending on the application needs, such as desired force, size and flexibility of the user and the table. The radius section 37 can be formed from the spring 42 and can be contoured to accommodate rounded or straight surfaces allowing for different table edge radii wherein the clip portion 30 can be used on wide variety of tables.

The spring 42 can generate a continuous mechanical force that clamps the table edge between the straight section 34 and the radius section 36, creating a positive mechanical interlock that does not depend on surface finish, material porosity, or the presence of air-tight sealing conditions. The spring force can remain substantially constant regardless of minor variations in table thickness, slight movements of the tray during use, or environmental conditions such as temperature or humidity. The constant force ensures that the clip portion 30 maintains its grip even when subjected to the various loads and disturbances encountered during typical use, such as a child pushing items across the mat, pulling on attached accessories, or bumping against the tray.

The spring 42 can accommodate table thickness variations of at least 0.5 inches to 4 inches, more preferably 0.25 inches to 3.5 inches, by flexing to expand or contract the open section 41 as needed. When attaching to a thin table, the spring 42 flexes only slightly, maintaining most of its spring force in reserve. When attaching to a thick table, the spring 42 flexes more substantially, utilizing more of its available deflection range. Across this entire range of thicknesses, the spring force remains within a functional range that provides secure attachment without excessive force that could damage table edges or make removal difficult. The continuous spring material from the straight section 34 through the radius section 37 ensures optimal stress distribution and structural efficiency. Stresses flow smoothly through the spring material without discontinuities or concentrations at interfaces wherein the continuous stress path maximizes fatigue life and allows the spring to withstand thousands of flexing cycles without cracking, yielding, or permanent deformation.

In embodiments, the clip portion 30 can have a padded portion 32 integrated within the cover 36 and in certain embodiments can be over-molded onto the spring 42 wherein the padded portion can provide a cushion against the sharp tables edge. The padded portion 32 can have a plurality of dimples 40 protruding from its surface, providing a soft and padded surface for the front of the clip portion 30. In certain embodiments, the padded portion 32 can have an increased thickness as shown in FIG. 10b through 10c or can be substantially the same thickness as the mat portion thickness 22 as shown in FIG. 7. The plurality of dimples 40 can extrude partially from the padded portion 32. The plurality of dimples 40 can be the same shape or can vary in shape depending on the user's needs. The plurality of dimples can be the same material as the mat portion 12 or can be varying material such as, for example, compression-molded liquid silicone, injection mold silicone, thermoplastic elastomers, polyurethane, Ethylene-vinyl acetate, latex rubber, or the like. In certain embodiments the plurality of dimples 40 can be omitted and the padded portion can have a pad extruding from or attached to the padded portion 32.

The padded portion 32 can be positioned at the radius section 36 of the clip portion 30, placing the cushioning element directly at the front surface of the table edge where a child is most likely to make contact during normal dining activities. The positioning of the padded portion 32 at this critical location provides protection against impacts from a child's head, face, hands, or body contacting the hard table edge. The plurality of dimples 40 can have individual dimple heights ranging from approximately 0.1 inches to 0.5 inches, more preferably 0.15 inches to 0.35 inches, protruding from the base surface of the padded portion 32. The dimples 40 create localized regions of increased material thickness that enhance the cushioning properties of the padded portion 32 while maintaining flexibility and conformability. Each dimple 40 can compress independently when impacted, distributing impact forces across multiple deformation zones rather than concentrating stress in a single location.

In certain embodiments, the dimples 40 can be arranged in various patterns across the surface of the padded portion 32, including uniform grids, staggered arrays, concentric patterns, random distributions, or decorative arrangements. The spacing between adjacent dimples can range from approximately 0.1 inches to 1 inch, with closer spacing providing more uniform cushioning and wider spacing providing distinct tactile features. The density of dimples per unit area can be varied across the padded portion 32, with higher density in regions expected to experience more frequent contact and lower density in less critical areas. The plurality of dimples 40 can be the same shape, the dimples can be configured as hemispheres, providing a smooth, rounded profile that is comfortable upon contact and easy to clean. Hemispherical dimples distribute impact forces uniformly in all directions and avoid sharp edges or corners that could concentrate stress or trap debris. Alternative uniform shapes can include cylindrical projections with rounded tops, truncated cones, or ellipsoidal forms.

In other embodiments where the plurality of dimples 40 vary in shape, different dimple geometries can be strategically positioned to optimize different performance characteristics in different regions. For example, taller, more compliant dimples might be positioned in the central region of the padded portion 32 where head impacts are most likely, while shorter, firmer dimples might be positioned near the edges where hand or arm contact is more common. Dimples of varying cross-sectional shapes such as, for example, circular, oval, rectangular, polygonal, or the like and can be intermixed to create specific tactile patterns or visual designs. In certain embodiments, the plurality of dimples 40 can be omitted entirely, and the padded portion 32 can instead feature a continuous pad without discrete protrusions. This continuous pad configuration can provide a smooth, uninterrupted cushioning surface that some users may prefer for aesthetic reasons or ease of cleaning. The continuous pad can have a uniform thickness or can incorporate internal features such as ribs, channels, or foam-like cellular structures to enhance cushioning without creating external surface irregularities as shown in FIG. 8.

In certain embodiments, the clip portion 30 can be shaped as shown in FIG. 7 or FIG. 8 wherein the padded portion 32 can extend in front of the spring 42 and form a forgivable surface that can provide a cushion 202 to the padded portion 32. The cushion 202 can be integral to the clip portion 30 or it can be coupled to the clip portion. The cushion 202 can be made of such as, for example, compression-molded liquid silicone, injection mold silicone, thermoplastic elastomers, polyurethane, Ethylene-vinyl acetate, latex rubber, or the like giving the user a padded section.

In embodiments, the clip portion 30 can be expanded to fit varying thicknesses of tables, making the tray versatile and adaptable to different environments. The clip portion 30 can have a first slot 44 and a second slot 43, with the second slot being substantially bigger than the first slot. The first slot 44 and/or at least one clip portion hole 55 can allow for the attachment of accessories, such as a tether 57 that can be attached to such as, for example, a plate, a cup, a child's toy, or the like allowing the accessory to be coupled to the clip portion. The second slot 43 can be a handle allowing the user to remove the portable tray with an attachment clip portion 30 from the table. The first slot 44 and the second slot 43 can vary in size and shape and can be such as, for example, square, rectangular, circular, polygonal or the like. In certain embodiments, the first slot 42 can be a plurality of holes that a tether end can stick into securing the tether to the clip portion 30. In other embodiments, the first slot 44 and the second slot 43 can be omitted.

The expandability of the clip portion 30 can be facilitated by the spring 42, which can provide the elastic force necessary to open the clip portion while maintaining sufficient clamping force across a wide range of table thicknesses. To attach the tray to a table, a user grasps the clip portion 30 by the second slot 43 and applies an opening force that flexes the spring 42, increasing the distance between the straight section 34 and the radius section 36. This expanded configuration allows the clip to be positioned over the table edge. When the user releases the clip portion 30, the spring force causes the clip portion to contract around the table edge, securing the tray in place.

The first slot 44 and the at least one clip portion hole 55 can provide attachment points for accessories that significantly expand the functionality and utility of the portable tray beyond simply providing a dining surface. By incorporating dedicated attachment features directly into the clip portion 30, the design allows users to secure items that might otherwise be knocked off the tray, dropped on the floor, or thrown by the child. This attachment capability addresses a common frustration for caregivers: the tendency of young children to intentionally or accidentally drop, throw, or push items off the table during meals.

In embodiments, the tether 57 that can be attached through the first slot 44 or the clip portion hole 55 can comprise such as, for example, flexible cord, strap, chain, ribbon, elastic band, or similar elongated connector with attachment features at both ends. One end of the tether 57 can be secured to the first slot 44 or the clip portion hole 55, while the other end attaches to an accessory such as, for example, a plate, cup, bowl, utensil, sippy cup, bottle, pacifier, spoon, fork, toy, or the like. When the child pushes, drops, or throws the tethered item, it falls only to the length of the tether and then hangs suspended rather than hitting the floor. This prevents loss or contamination of the item, reduces cleanup requirements, and can help teach the child about cause-and-effect relationships.

In embodiments, the tether 57 can have a length ranging from approximately 6 inches to 24 inches, more preferably 10 inches to 18 inches, allowing the attached accessory sufficient freedom of movement for the child to use it while preventing it from falling completely off the table or reaching the floor. Shorter tethers 57 provide more restrictive containment and keep accessories closer to the mat surface, while longer tethers allow greater freedom of movement but may permit accessories to swing farther when dropped. The tether length can be adjustable through the use of sliding stops, knots, or adjustable fasteners, allowing caregivers to customize the restraint based on the specific accessory and situation.

The first slot 44 can have dimensions suitable for common tether attachment mechanisms. For tethers with looped ends, the first slot 44 might have a width of approximately 0.25 inches to 0.75 inches and a length of approximately 0.5 inches to 1.5 inches, allowing the loop to be threaded through the slot and then passed over itself to create a secure cinch. For tethers with clip ends, snap ends, carabiner-style fasteners, or other mechanical fasteners, the first slot 44 dimensions can be selected to accommodate the specific fastener geometry while preventing inadvertent detachment.

The clip portion hole 55 can have a diameter or characteristic dimension ranging from approximately 0.125 inches to 0.75 inches, providing an opening through which a tether end can be inserted. The clip portion hole 55 can be circular, oval, slotted, keyhole-shaped, or any other suitable configuration. In embodiments, the clip portion hole 55 can be sized to create a friction fit with the tether material, wherein the tether is held in place by compression and friction rather than by mechanical features. In other embodiments, the clip portion hole 55 can be larger to easily accommodate tethers with enlarged ends, knots, beads, toggles, or other retention features. In other embodiments, the clip portion hole 55 can allow the system 10 to be secured to the table by such as, for example, hook and loop, fastener, pin or the like.

In embodiments, the positioning of the first slot 44 and the clip portion hole 55 within the clip portion 30 can be selected to keep attached tethers out of the way during normal use while still maintaining easy access for attachment and detachment. The first slot 44 can be positioned near the radius section 36 where it is readily accessible to the caregiver but not in a location where tethers might interfere with the mat portion 12 or become entangled with items placed on the tray. Alternatively, the first slot 44 can be positioned within the straight section 34, providing a more protected location that keeps tethers closer to the table edge and reduces the likelihood of the child grasping and pulling on the tether itself.

The clip portion hole 55 can be positioned at various locations around the clip portion 30 depending on the desired tether routing and accessibility. Multiple clip portion holes 55 can be provided at different locations, allowing the caregiver to select the most suitable attachment point for a particular accessory or situation. For example, clip portion holes 55 can be positioned on the left and right sides of the clip portion 30, allowing tethers to be routed to either side of the mat depending on where accessories are placed. Additional clip portion holes 55 can be positioned at the top or bottom of the clip portion 30 to provide further attachment options.

In embodiments, the second slot 43 can be substantially larger than the first slot 44, and can serve a different functional purpose as a handle for gripping and manipulating the clip portion 30. The handle function is particularly important during removal of the tray from the table, when the user must overcome the spring force holding the clip in place. By providing a defined gripping location with adequate size for adult fingers, the second slot 43 makes the removal operation easier, more controlled, and less likely to result in the user's hand slipping off the clip or applying excessive force that could damage the tray or table. The second slot 43 can have dimensions ranging from approximately 0.75 inches to 2 inches in width and 1 inch to 3 inches in length, providing sufficient space for an adult to insert one or more fingers for gripping. The edges of the second slot 43 can be rounded or filleted with radii of approximately 0.05 inches to 0.25 inches to provide a comfortable gripping surface that does not create pressure points or sharp edges against the user's fingers. In some embodiments, the interior surfaces of the second slot 43 can be textured with such as, for example, ridges, dimples, or other surface features to enhance grip and prevent the user's fingers from slipping during the application of removal force.

In other embodiments, the second slot 43 can serve secondary functions beyond its primary role as a handle. The second slot 43 can provide a convenient location for hanging the tray for storage when not in use, allowing it to be suspended from a hook, peg, rod, or other hanging fixture. This hanging storage capability keeps the tray visible and readily accessible while freeing up drawer or cabinet space for other items. The second slot 43 can also serve as a visual indicator of where to grip the clip, making the removal operation more intuitive for first-time users who may not be immediately familiar with how the clip mechanism functions.

In other embodiments, the edges of the first slot 44, the clip portion hole 55, and the second slot 43 can be reinforced with increased material thickness, additional ribbing structures, or by incorporating harder materials or reinforcement elements to prevent tearing, elongation, or other forms of damage under repeated use. The slots and holes represent discontinuities in the clip structure where stress concentrations can develop, particularly when tethers are pulled taut or when removal forces are applied. Reinforcement around the perimeters of these openings distributes stresses over a larger area and increases the durability and service life of the clip portion 30.

The method of use comprises the portable tray assembly being secured to a table through an attachment process that takes advantage of the spring-loaded clip mechanism. The user begins by providing a portable tray assembly comprising a flexible mat portion 12 formed from food-grade thermoplastic rubber and a clip portion 30 with a spring element covered by a thermoplastic rubber cover. The mat portion can be unrolled from its storage configuration if it has been stored in a rolled state within the clip portion, or it can be removed from whatever storage location or carrying container the user has transported it in.

The user then positions the mat portion on a top surface of the table where the child will be eating. The mat portion can be oriented and positioned based on the available space, the location where the child will be seated, and the caregiver's preferences for item placement. The bottom surface of the mat portion contacts the table surface, and any anti-slip coating, textured surface, or tacky surface features on the bottom surface begin to engage with the table to resist sliding.

To attach the clip portion 30 to the table edge, the user expands an open section of the clip portion to accommodate the table edge. This expansion can be accomplished by manually pulling the radius section away from the bottom surface of the mat portion, which flexes the spring element and increases the distance between the straight section and the radius section. The amount of force required to expand the open section depends on the spring constant of the spring element, with stiffer springs requiring more force and more compliant springs requiring less force. The expansion creates a gap sufficiently large to receive the table edge regardless of the table's thickness within the accommodation range of the clip.

The user then inserts the table edge into the open section between the straight section and the radius section of the clip portion. The clip portion 30 can be positioned so that the table edge enters the open section, with the top surface of the table contacting or closely approaching the straight section of the clip and the front edge of the table positioned within the curved profile of the radius section. The user can adjust the position of the mat portion 14 and clip portion 30 as needed to achieve proper alignment and positioning relative to the child's seating location.

Once the table edge is properly positioned within the open section, the user releases the clip portion, allowing the spring element to exert constant pressure against the table edge to secure the portable tray assembly to the table. The spring force causes the radius section to contract toward the straight section, clamping the table edge between these two surfaces. The continuous spring pressure maintains a secure attachment that resists sliding, lifting, or other movements that might occur during use. The flush contact between the bottom surface of the mat portion and the straight section of the clip portion with the table surface ensures stability and prevents rocking or tilting.

When the meal is complete and the user wishes to remove the portable tray assembly from the table, the user can grip a handle formed by a second slot in the clip portion. The second slot provides a convenient gripping location where the user can insert one or more fingers and apply the force necessary to flex the spring element and expand the open section. By gripping the handle, the user can control the removal process and prevent the tray from suddenly releasing and potentially spilling any remaining contents. The user pulls the radius section away from the table edge while lifting the mat portion, separating the clip from the table edge and freeing the tray assembly.

During use of the portable tray assembly, the user can enhance functionality by attaching a tether to an accessory such as a plate, cup, bowl, utensil, or toy, and securing the tether to the clip portion 30 through a first slot formed in the clip portion or through a clip portion hole. The tether prevents the accessory from falling to the floor if the child drops, pushes, or throws it, keeping the accessory clean and within reach. The tether can be attached before placing the accessory on the mat, or it can be attached after the accessory is already in use. Multiple tethers can be attached simultaneously to secure multiple accessories, providing comprehensive containment of items that the child might otherwise displace.

Throughout the use of the portable tray assembly, the clip portion includes a padded portion positioned at the radius section, which cushions contact between a child and the table edge with the padded portion during use. As the child moves, reaches for items, shifts position, or reacts to stimuli, any contact between the child's head, face, hands, arms, or body and the table edge is cushioned by the soft, resilient material of the padded portion rather than impacting the hard table surface directly. This cushioning reduces the risk of injury and makes the dining experience safer and more comfortable for the child.

In embodiments where the padded portion comprises a plurality of dimples protruding from its surface, these dimples contact the child during cushioning, providing localized areas of enhanced compliance and energy absorption. Each dimple can compress independently, distributing impact forces and providing a soft, textured surface that further enhances comfort and safety. The dimples create a distinctive tactile sensation that may be interesting or soothing to the child, potentially reducing fussiness or resistance to sitting at the table.

In embodiments where the padded portion comprises a cushion extending in front of the spring element, this cushion provides a forgiving surface upon contact that absorbs impact energy through compression and deformation. The cushion can extend beyond the spring structure, providing a larger contact area and ensuring that any impact is absorbed by soft material rather than by the harder spring structure beneath. The forgiving surface accommodates contact from various angles and impact velocities, providing consistent protection regardless of how the child moves or contacts the table edge.

During the meal, spilled liquids are contained within a raised lip surrounding an outside perimeter of the mat portion, preventing the liquids from reaching the table surface or floor. When the child spills milk, juice, water, soup, or other liquids, these liquids spread across the top surface of the mat portion but are stopped by the raised lip before they can run off the edge. This containment significantly reduces cleanup requirements and prevents liquids from dripping onto the child's clothing, the chair, or the floor. The caregiver can allow the meal to continue without immediate cleanup, or can quickly wipe up the contained spill without having to address a larger mess on surrounding surfaces.

After the meal is complete and the tray has been removed from the table, the user can clean the tray assembly by rinsing it with water, washing it with soap and water, wiping it with disinfecting solutions, or placing it in a dishwasher. The food-grade thermoplastic rubber material withstands these cleaning processes without degradation, maintaining its properties and appearance through repeated cleaning cycles. The smooth surfaces, rounded edges, and accessible geometry of the tray make thorough cleaning straightforward and efficient.

Following cleaning and drying, the flexible mat portion can be rolled starting from the second end and progressing toward the first end where the clip portion is located. The rolled mat can be inserted into the interior space of the clip portion, where it is held securely for storage and transport. This compact configuration protects the food-contact surfaces from contamination and makes the tray easy to pack in a diaper bag, purse, or other carrying container for use at the next meal, whether at home, at a restaurant, at a friend's house, or any other dining location.
