TECHNICAL FIELD

The present application relates to the technical field of maternal and baby products, particularly to a brassiere.

BACKGROUND

As an intimate apparel product, brassieres typically require insertion of molded cups into designated positions during manufacturing to achieve optimal fit and support functions. In modern brassiere production processes, an opening is conventionally incorporated into the design to facilitate installation of the molded cups. The molded cups are inserted through this opening to complete assembly, a technique widely employed in industrial brassiere manufacturing.

However, conventional designs of cup insertion openings exhibit several technical deficiencies. Particularly after prolonged use or repeated washing, the opening edges are prone to tearing or deformation due to external forces such as stretching and friction. The insufficient structural strength of these opening edges may lead to damage during cup insertion, significantly compromising the durability of the opening section. Furthermore, inadequate elasticity along the opening edges may result in suboptimal installation smoothness for the molded cups, while simultaneously adversely affecting the overall structural stability and wearing comfort of the brassiere.

SUMMARY

In view of the deficiencies in prior art, the present application provides a brassiere capable of resolving issues of short service life and susceptibility to damage at the cup insertion opening.

To address the aforementioned technical problems, one technical solution adopted in embodiments of this application is to provide a brassiere comprising: a housing forming an accommodation space therein, the housing having an opening communicating between interior and exterior of the accommodation space; a molded cup disposed within the accommodation space; and an elastic adhesive film and a reinforcement strip bonded via the elastic adhesive film to a peripheral region of the opening.

In one embodiment, the opening is disposed on the inner layer.

In one embodiment, the reinforcement strip is bonded via the elastic adhesive film to a surface of the inner layer facing the outer layer.

In one embodiment, the molded cup is fixed to the housing at fixation regions comprising an upper fixation region positioned above a wearer's nipple during use and a lower fixation region positioned below the wearer's nipple during use.

In one embodiment, the molded cup is adhesively fixed to the housing at the fixation regions.

In one embodiment, the upper fixation region has an extension length smaller than that of the lower fixation region.

To address the aforementioned technical problems, yet another technical solution adopted in embodiments of this application is to provide a brassiere comprising: a housing forming an accommodation space therein, the housing having an opening communicating between interior and exterior of the accommodation space; a molded cup disposed within the accommodation space and fixed to the housing at fixation regions comprising an upper fixation region positioned above a wearer's nipple during use and a lower fixation region positioned below the wearer's nipple during use; and an elastic adhesive film and a reinforcement strip continuously bonded via the elastic adhesive film along a circumferential direction of the peripheral region of the opening.

In one embodiment, the molded cup is adhesively fixed to the housing at the fixation regions.

In one embodiment, the upper fixation region has an extension length smaller than that of the lower fixation region.

The embodiments of this application provide a brassiere comprising: a housing forming an accommodation space with an opening; a molded cup disposed within the accommodation space; and an elastic adhesive film and a reinforcement strip bonded via the elastic adhesive film to a peripheral region of the opening.

In the embodiments of the present application, the brassiere may comprise shoulder straps 10, a housing 20, molded cups 30, an elastic adhesive film 40, and a reinforcement strip 50.

As shown in FIGS. 1 and 2, in one embodiment, the number of shoulder straps 10 is two, both connected to the housing 20. The primary functions of brassiere shoulder straps are to provide support and stability, ensuring better body conformity while helping distribute breast weight to reduce pressure on the back and shoulders. In some embodiments, the brassiere may exclude shoulder straps, such as in strapless brassiere designs.

The housing 20 forms an accommodation space therein and is provided with an opening 21 that communicates between the interior and exterior of the accommodation space. The opening 21 serves to allow insertion of the molded cup 30 into the accommodation space. In some embodiments, the housing may be made of fabric materials, specifically including but not limited to nylon, spandex, polyester, Lycra fabric, cotton blends, etc.

The molded cups 30 are disposed within the accommodation space. The number of molded cups 30 may be two, corresponding to two accommodation spaces respectively designed to accommodate each molded cup 30. The primary functions of the brassiere's molded cups 30 include providing breast support, shaping and protection, while enhancing wearing comfort and aesthetic appearance. The molded cups 30 may be composed of one or more materials selected from polyurethane foam, polyester fiber, and non-woven fabric.

As shown in FIGS. 2, 3, 4, and 5, the reinforcement strip 50 is bonded via the elastic adhesive film 40 to a peripheral region of the opening 21.

The elastic adhesive film 40 is formed by curing adhesive materials, which may include hot-melt pressure-sensitive adhesive, water-based environmentally friendly adhesive, reactive polyurethane hot-melt adhesive, acrylic adhesive, or polyurethane adhesive. These adhesive types all exhibit excellent bonding performance and environmental characteristics, meeting various application requirements. The hot-melt pressure-sensitive adhesive features rapid curing and strong initial tack, making it suitable for applications requiring quick bonding with high initial adhesion demands. The water-based environmentally friendly adhesive is renowned for being eco-friendly, non-toxic, and odorless, better aligning with modern health-conscious lifestyles. The reactive polyurethane hot-melt adhesive combines the superior elasticity of polyurethane with the rapid curing properties of hot-melt adhesives, providing effective bonding while maintaining garment softness and comfort. Acrylic and polyurethane adhesives each have distinct characteristics-acrylic adhesive demonstrates excellent weather resistance and water resistance, making it suitable for outdoor or humid environments, while polyurethane adhesive offers high strength and wear resistance, making it more appropriate for garment areas subject to significant tension or abrasion. Selecting the appropriate adhesive type can further enhance garment quality and durability to meet diverse consumer needs.

In one embodiment, the reinforcement strip 50 is continuously arranged along the circumferential direction of the opening 21 edge. In this embodiment, the reinforcement strip 50 forms a complete loop around the opening 21. It should be understood that in other embodiments, the reinforcement strip 50 may be disposed only at partial locations along the opening 21 edge, not necessarily forming a closed loop, which is not limited in the embodiments of this application. When the reinforcement strip 50 is continuously arranged along the opening 21 edge, it can effectively distribute stress acting on the opening edge, preventing deformation, tearing, or damage caused by external forces, thereby improving overall structural strength and durability. Strategically placing the reinforcement strip 50 at key locations allows for targeted reinforcement based on stress requirements, enhancing critical areas while avoiding material waste. The loop-shaped reinforcement strip 50 provides uniform support to the opening 21 edge, preventing damage during insertion of the molded cup 30 through the opening 21, while reducing edge warping or unevenness. In some embodiments, the width of reinforcement strip 50 ranges approximately between 2 mm-8 mm, such as 2 mm, 6 mm, or 8 mm.

As shown in FIGS. 1, 2, 3, and 5, in one embodiment, the housing 20 comprises an inner layer 22 and an outer layer 23 arranged in superposition. The inner layer 22 and outer layer 23 remain unbonded in the region corresponding to the accommodation space, while being at least partially bonded together in overlapping regions outside the accommodation space to form the accommodation space between the inner layer 22 and outer layer 23.

This structural design provides the accommodation space with excellent stability and independence. The inner layer 22 directly contacts components placed within the accommodation space such as the molded cup 30, offering a soft touch surface that prevents scratching of the molded cup 30. The outer layer 23 serves protective and reinforcing functions, enhancing the overall strength of the housing 20. By partially bonding the inner layer 22 and outer layer 23 in overlapping regions outside the accommodation space, this configuration maintains the accommodation space while forming a relatively stable integrated structure, preventing separation or misalignment between the inner layer 22 and outer layer 23. Consequently, this ensures reliable brassiere structural integrity and provides users with improved wearing comfort.

In one embodiment, the opening 21 is disposed on the inner layer 22. The inner layer 22 is positioned closer to the wearer's body when the brassiere is worn, while the outer layer 23 is positioned farther from the wearer's body.

This configuration allows components such as the molded cup 30 to be conveniently inserted into or removed from the accommodation space from the side closer to the body, facilitating easier operation. Since the inner layer 22 is adjacent to the wearer's body, locating the opening 21 here prevents interference with outer garments during installation or adjustment of the molded cup 30, thereby improving usability. Moreover, when the brassiere is worn, the opening 21 remains concealed against the skin, maintaining the brassiere's external appearance integrity and aesthetic appeal while optimizing wearer comfort.

In one embodiment, the reinforcement strip 50 is bonded via the elastic adhesive film 40 to a surface of the inner layer 22 facing the outer layer 23. This means the reinforcement strip 50 is positioned within the accommodation space between the inner layer 22 and outer layer 23, making it invisible from the exterior of the brassiere. This design preserves the garment's aesthetic continuity while preventing any potential friction between the reinforcement strip 50 and the wearer's skin during use.

In one embodiment, the molded cup 30 is fixed to the housing 20 at fixation regions including an upper fixation region 31 and a lower fixation region 32. When worn, the upper fixation region 31 is positioned above the wearer's nipple while the lower fixation region 32 is positioned below the nipple.

This dual fixation configuration provides precise breast support: the upper fixation region 31 effectively lifts the breast to create optimal shaping and prevent gravitational sagging, while the lower fixation region 32 bears the primary support load to evenly distribute breast weight and reduce pressure. This design offers stable support during movement, significantly enhancing wearing comfort and functionality. Furthermore, the strategic placement of these fixation regions accommodates various breast shapes by providing customized support points along the body's natural contours, improving the brassiere's adaptability to different body types and meeting diverse consumer needs.

In one embodiment, the molded cup 30 is adhesively fixed to the housing 20 at the fixation regions. Specifically, the molded cup 30 is bonded to the housing 20 at both the upper fixation region 31 and lower fixation region 32 through adhesive bonding.

This adhesive fixation method offers simple and convenient operation while ensuring stable connection between the molded cup and housing. During production, it effectively improves manufacturing efficiency and reduces production costs. Additionally, adhesive fixation creates a smoother overall appearance for the brassiere by eliminating potential protrusions or gaps that may occur with alternative fixation methods, thereby enhancing both wearing comfort and aesthetic appeal. Furthermore, proper adhesive selection ensures the fixation integrity between the molded cup and housing remains unaffected through extended wear and washing cycles, prolonging the brassiere's service life.

In one embodiment, the upper fixation region 31 has an extension length shorter than that of the lower fixation region 32.

This design provides stronger support in the lower portion where most breast weight is concentrated. The extended lower fixation region better distributes and bears this weight, preventing breast sagging due to insufficient support. Simultaneously, the shorter upper fixation region avoids excessive constriction on the upper breast area, maintaining natural breast shape and breathing space for greater freedom of movement and comfort, further optimizing the wearing experience for different breast types.

In one embodiment, the opening 21 has an elongated shape with edge portions comprising two linear side edges 211 and two arcuate end edges 212. This design eliminates sharp corners at the opening ends, making them less prone to tearing and thereby extending the opening's durability. The configuration combines fluid, gentle curves with stable linear edges—the arcuate end edges better conform to body contours, reducing discomfort from abrupt edge shapes during wear, while the linear side edges facilitate precise positioning during manufacturing, ensure dimensional consistency, and simplify assembly with other components like connecting bands or decorative elements, ultimately improving overall craftsmanship and product durability.

In one embodiment, the end edges 212 are circular arcs that, in the brassiere's non-stretched state, have a diameter greater than the spacing between the side edges 211. This design distributes stress away from the ends when the opening 21 is stretched, preventing force concentration at the edges and further enhancing the opening's lifespan.

The embodiments of this application provide a brassiere comprising: a housing forming an accommodation space with an opening; a molded cup disposed within the accommodation space; and an elastic adhesive film and reinforcement strip bonded to the opening edge region. This configuration prevents opening deformation or tearing caused by washing or stretching, extends the opening's service life, increases edge elasticity, and facilitates easier insertion of the molded cup through the opening.
