(My provisional application No. 61/817,452, dated Apr. 30, 2013, EFS ID 15649207)
Eating habits of the western society generally include the utilization of a plate to serve food and eating utensils in the form of a spoon, fork and knife. Disposable dishware and eating utensils are very popular in today's high paced, disposable society. Along with the traditional American eating utensils fast food options have led to the adoption of Asian utensils as well—chopsticks and tongs. Tongs are very popular for serving salads and similar foods onto plates. The popularity of tongs has increased as a way to avoid any direct contact between the hands and food. Tongs as a serving utensil is substantially more convenient than the traditional fork, spoon or knife. This invention is an inexpensive solution to bring together the traditional forks, spoons and knifes with an optional tong. The solution consists of a set of forks, spoons and knives which are equipped with a uniform interconnecting lock at the tip of the handle on every set's member. Two members of the set form a pincers-like shape by connecting together through a uniform lock. While eating it's easy to assemble the utensils (like fork and knife) and use them as tongs and then easily disassemble them and continue to use them as regular utensils. There are six variations of improvised tongs (fork-fork, fork-spoon, fork-knife, spoon-spoon, spoon-knife and knife-knife).
Disposable dishware has also become a very popular, convenient and inexpensive way to serve food. It is used for picnics, parties, eating out, etc. The most common materials for producing disposable dishware include paper, Styrofoam, nontoxic plastic and metal foil. Various designs and shapes of disposable dishware are available on market today. The fast-food industry also utilizes disposable containers that besides their initial purpose (transporting food) it can be used as dishware. Usually food containers consist of a box and an attached cover. Some prior arts propose a container with a separate cover, but it has not received market demand and has been left behind.
When food is served on a plate and needs a temporary cover from dust, sun, wind, insects, etc. the simple way is to cover the plate with a similar plate. The current invention equips plates with an integrated uniform fastener arranged along the rim so that every plate can be snapped to any counterpart from a similar set. When the two plates are interlocked together they create a seal, but not a leak proof seal. The purpose of the invention is to create a simple, inexpensive option to any plate to act as a detachable cover to another plate from the same set to create a temporary container.
It is a further objective of the invention to provide dishware and utensils which can be manufactured by methods commonly used in the industry, without extensive modification and without incurring excessive manufacturing costs. Unlike all similar prior arts (set forth below list) this invention is not for a container and tongs. It is an option for regular disposable dishware to become a temporary container as well as an option for a disposable fork, spoon or knife to become a part of a temporary tong.
Improved utensil construction in which every member of a set (fork, knife and spoon) include a lock at the end of the handle to enable any two members to be connected together to form tongs. When connected together, the two arms free ends are separated. By applying pressure to the arms the free ends of the arms pushed together to engage the material positioned between the free ends of the tools. As soon as the pressure is released, the ends of the tongs will spring apart to disengage the object held.
Every member of the utensil set has an absolutely identical uniform lock. One of the preferred lock designs consists of two extrusions (FIG. 2u) with gaps between them that become the receptacles for the same extrusions of another utensil with a similar interlock. With the two uniform locks facing each other applying slight pressure on both utensils will cause the two utensils to snap together.
There are unlimited designs of interlock styles. A few examples are displayed in FIG. 5u-12u. The main objective of the lock construction is ease of connection and disconnection of two members of a utensil set. Connected utensils (FIG. 3) can form six types of tongs—knife-knife, fork-fork, spoon-spoon, fork-spoon, fork-knife and spoon-knife.
Some preferred modifications are made to a regular disposable knife to aid in food service when engaged as tongs. One Modification is a curve to the spade as depictured on FIG. 13u. It has small prongs on the tip of the blade for better food gripping. This shape is also useful when the knife used apart from tongs. The spade-like shape is more efficient when used as a utensil knife, butter spreader or food spade. Prongs on the blade of the knife are useful for food cutting and slicing.
The principal of the universal interlock pertains also to disposable dishware. The dishware's female and male fasteners run along the rim in an alternating order. Every member of the dish set can be matched so all male extrusions of one member fill female intrusions of the other. For an inexpensive, less durable grip, there is rectilinear profile (FIG. 46a) for male and female parts, made from pliable material (foam, plastic, paper etc.) fit tightly and provide a satisfactory grip for covering purpose. For a more durable or leak proof fastener there are variety of profiles (FIG. 46b-46e) which substantially complicates mold production and raises the price of manufacturing process.
The main purpose of the current invention is to furnish a regular disposable dishware with an option to be converted into a container. The price of the final product (with option) should be the same as present (non-optional) analogs on the market. The invention consists of variety of embodiments which satisfies the purpose of the invention—simplicity, inexpensive and unobtrusive conversion option to the final costumer.
One of the preferred fastener embodiments is a pair of female grooves (2) and male extrusions (1) fasteners (FIG. 1-3). When two members of the same set face each-other the upper extruded groove matches the lower intruded groove, and upper intruded groove matches lower extruded one. It creates a zip-like engagement attachment. This embodiment has line-up notches (3) to simplify two members snapping alignment.
Another embodiment is a plurality of button-like fasteners along the rim (FIG. 4-6). Unlike previous embodiments this one gives an ability to align and attach two members in several angles. Quantity of snapping positions are proportional to the quantity of fasteners.
One of the embodiments consists of extruded parts and wholes instead of intruded parts. It allows plates to be stacked more efficiently (FIG. 14). Every extrusion tightly fits into corresponding hole.
Any plate has an additional option to be snapped to itself, based on the order that the fasteners are arranged. (FIG. 17-18).
The variety of plates shapes is unlimited, only one condition has to be observed—every member of the same set has to be mirrored to another when facing to each-other (FIG. 31-38)
Depth of members in a same set can be varied. A bowl can be paired with a plate, etc. One of the embodiments has a smaller set member snapped by its rim edges inside a bigger member with a special extrusions (FIG. 23-24).
For the best locking results male (extrusion) fasteners have to be tightly fit to corresponding female (intrusion) fasteners (FIG. 46a). This embodiment is the most inexpensive way to create a satisfactory attachment. In more expensive embodiments there are a variety of more durable shapes of attachments. (FIG. 46b-46e)
Dishware with a perforated interlocking flap (preferred for paper plates) gives an option to tear the flaps at the perforation so that the flaps may be interlocked with the flaps of a set mate to create a temporary container (FIG. 6-8 & FIG. 25-30).
Set of utensils (forks, spoons, knifes) equipped with a uniform interlock on the tip of the handle gives an option to convert any two members of a utensil set into temporary tongs.
Set of identical dishware (plates, dishes, bowls, trays etc.) with uniform fasteners located along the rim for a container option. All similar plates in the same set can be snapped onto each other. The fasteners comprise of a complementary series of elements projecting upward and downward on the rim of the plate. The fasteners engage when two plates are facing each other and pressed against each other.
