The invention relates to eating utensils. More particularly, this invention relates to sets of portable, reusable eating utensils.
Eating utensils are often made of stainless steel. Unfortunately, stainless steel is relatively heavy. Increased weight is detrimental to the portability of such utensils, particularly for use in travel where compact, lightweight equipment is desirable. Steel utensils which are light enough to be easily portable tend to be small and thin, making them uncomfortable and difficult to use.
A conventional table setting usually comprises a knife, a fork, and a spoon. In order to be portable, it is desirable to secure all three components as a unit, lest the individual components separate within a bag and become lost. One possible solution is to provide carrying cases with portable utensil sets. However, such cases add weight to the set while only providing limited additional functionality.
Another possible solution that is both lightweight and portable is an all-in-one utensil, such as the one disclosed by U.S. Pat. No. 9,265,372 to Stewart-Stand. However, many food items must be held in place using a fork while they are cut into bite-sized pieces using a knife. An all-in-one utensil cannot do both of these necessary tasks simultaneously, making it awkward and difficult to eat certain foods. Further, the functional parts of the utensil, such as the spoon bowl or fork tines, must necessarily be located at either end of the handle, forcing the user to grip the handle in the middle. This makes it more awkward to use and makes it more likely that the user's hand may accidentally come in contact with the food, which is not hygienic and may also inflict burns on the user.
Another solution is to use disposable utensils for meals eaten outside the home.
However, this is both wasteful and not environmentally friendly. Additionally, several countries have proposed bans on such single-use plastics because of the environmental impact. Accordingly, a reusable solution will be increasingly desirable and potentially a necessity in the future.
Whether portable or not, most utensils are designed so that, when rested on a surface, the part of the utensil intended to enter a person's mouth is in contact with that surface. When one is using utensils outside of the home, one cannot always be certain of the cleanliness of the surfaces on which one may need to rest the utensil. A more hygienic solution, where the functional parts of the utensil do not touch the surface on which they rest, is desirable.
It is therefore an object of this invention to provide a hygienic, light-weight, ergonomic, portable, self-containing, and reusable utensil set with all the functionality of a full table setting.
In one aspect, the invention relates to a portable, self-contained, reusable utensil apparatus. The utensil apparatus comprises a knife portion and a fork portion. The fork portion comprises a large, ergonomic, hollowed-out fork handle and a fork head attached to the open edge of said fork handle. The knife portion similarly comprises a large, ergonomic, hollowed-out knife handle and a blade attached to the open edge of said knife handle.
The fork head inserts into the knife handle and the knife blade inserts into the fork handle to interlock the fork and knife handles into a single hollow unit, while also protecting the functional components of the knife portion and the fork portion from being contaminated by unsanitary transportation conditions. The fork portion and the knife portion are self-centering; they do not need to be inserted straight into the other in order to properly interlock. As they are inserted further into the respective handle opening, curved edges on the sides of the handles cause the locking features on each respective utensil to align with the locking position.
In another aspect, the utensil apparatus further comprises a spoon portion. The spoon portion comprises a spoon handle and a bowl attached to one end of said spoon handle. The spoon portion may be stored inside the interlocked fork portion and knife portion to protect it from contamination and misplacement.
In yet another aspect, the utensil apparatus further comprises a straw. The straw is a hollow and substantially cylindrical. The straw may have an angular bend partway along its length. The straw may be stored inside the interlocked fork portion and knife portion to protect it from contamination and misplacement.
In still yet another aspect, the utensil apparatus further comprises the spoon and straw. A groove is formed in a surface of the spoon handle, into which the straw fits snugly. The straw and spoon portion together may be stored inside the interlocked fork portion and knife portion.
In accordance with one aspect of the invention, a utensil apparatus comprises a fork portion and a knife portion. The fork portion comprises a fork handle and a fork head. The fork handle comprises first and second fork walls and a fork cross wall extending between the first and second fork walls. The fork head extends from the first fork wall. The knife portion comprises a knife handle and a blade. The knife handle comprises first and second knife walls and a knife cross wall extending between the first and second knife walls. The blade extends from the first knife wall. The first and second fork walls and the fork cross wall define, at least in part, a fork enclosure. The first and second knife walls and the knife cross wall define, at least in part, a knife enclosure. The fork portion is configured to engage with the knife portion to form a connected configuration in which the fork head is housed, at least in part, within the knife enclosure, and the blade is housed, at least in part, within the fork enclosure.
In another embodiment, the fork first wall is curved and the fork second wall is substantially planar.
In yet another embodiment, the knife first wall is curved and the knife second wall is substantially planar.
In still yet another embodiment, the fork cross wall is U-shaped.

A knife cross wall 314 extends between the first knife wall 308 and the second knife wall 308. Preferably, the fork cross wall 314 extends from the periphery of the first knife wall 306 except at the first knife edge 310. The knife cross wall 314 extends substantially perpendicularly from the portion of the periphery of the first knife wall 306 that does not include the first knife edge 310. The knife cross wall 314 preferably extends from the second knife wall 308 along the periphery of the second knife wall 308 except at the second knife edge 312.

The procedure for connecting the fork portion 200 and the knife portion 300 is initiated by moving the second fork head end 253 towards the second blade end 353. The first head surface 252 should be facing the first blade surface 352, as shown in the orientation depicted in
The fork handle 202 and the knife handle 302 are then brought into closer proximity with each other. As they are brought closer together, the fork tab 258 will come into contact with the second knife wall 308, such as at the second knife edge 312. This contact will cause the fork head 250 to deform and flex slightly (in a direction towards the second fork wall 208) as the fork tab 258 moves along the second knife wall 308. At about the same time, the knife tab 358 will come into contact with the second fork wall 208, such as at the second fork edge 212. This contact will cause the blade 350 to deform and flex slightly (in a direction towards the second knife wall 308) as the knife tab 358 moves along the second fork wall 208.
The fork handle 202 and the knife handle 302 are continued to be brought closer together until the fork cross wall edges 220 engage with the knife cross wall edges 320. Preferably, the fork cross wall edges 220 and the knife cross wall edges 320 are shaped such that they are able to mateably engage, with the fork cross wall 214 and the knife cross wall 314 forming a generally continuous surface. When the fork cross wall edges 220 engage with the knife cross wall edges 320, the first fork edge 210 is brought into contact with the second knife edge 312, and the second fork edge 212 is brought into contact with the first knife edge 310. Preferably, when the first fork edge 210 contacts the second knife edge 312 and the second fork edge 212 contacts the first knife edge 310, the fork tab 258 will engage with the knife slot 318 and the knife tab 358 will engage with the fork slot 218. The engagement of the fork tab 258 with the knife slot 318 causes the fork head 250 to revert back to its original posture. Similarly, the engagement of the knife tab 358 with the fork slot 218 causes the blade 350 to revert back to its original posture.
The engagement of the fork tab 258 and the knife tab 358 with the knife slot 318 and the fork slot 218, respectively, helps to secure the fork portion 200 and the knife portion 300 together.
The releasing of the fork portion 200 from the knife portion 300 will now be described. When sufficient force is applied to pull the fork portion 200 apart from the knife portion 300, the fork and knife tabs 258, 358 will disengage from the knife and fork slots 318, 218, respectively, causing a deformation and flexing of the fork head 250 and the blade 350. This deformation and flexing of the fork head 250 and the blade 350 allow the fork and knife tabs 258, 358 to slide along the second knife and fork walls 308, 208, respectively. When the fork tab 258 moves past the second knife edge 312, the fork head 250 can revert back to its original posture. Similarly, when the knife tab 358 moves past the second fork edge 212, the blade 350 can revert back to its original posture. The fork portion 200 and the knife portion 300 are now separated and can be used separately.

The spoon portion 400 is preferably sized so that it fits within the cavity 150 when the fork portion 200 and the knife portion 300 are connected together. Referring to
Referring to
In one embodiment, the utensil apparatus 100 comprises the spoon portion 400 and the straw 500. In this embodiment, a groove 414 is formed on the first spoon surface 406, as shown in
The utensil apparatus 100 preferably comprises at least the fork portion 200 and the knife portion 300. The spoon portion 400 and/or the straw 500 may be left out of the utensil apparatus 100 or may form part of the utensil apparatus 100.
When the fork portion 200 and the knife portion 300 are connected together, the first and second fork walls 206, 208, the fork cross wall 214, the first and second knife walls 306, 308, and the knife cross wall 314 generally define an enclosure (i.e. the cavity 150) that is preferably sealed. This ensures that the fork head 250 and the blade 350 are protected from contamination as they are prevented from coming into contact with foreign substances or foreign surfaces when the fork portion 200 and the knife portion 300 are connected together. If the utensil apparatus 100 includes the spoon portion 400 and/or the straw 500, the spoon portion 400 and/or the straw 500 are also protected from contamination when placed within the cavity 150 after the fork portion 200 and the knife portion 300 are connected together.
One or more of the components of the utensil apparatus 100 may be formed from plastic, using, for example, injection moulding techniques. By using plastic, the utensil apparatus 100 may be reusable and is sturdy enough for repeated uses.
It will be appreciated by those skilled in the art that the preferred embodiment has been described in some detail but that certain modifications may be practiced without departing from the principles of the invention.
