Abstract

A constructible utensil (1) has a handle (2) and a head (3) of biodegradable wood material. The handle has a slot (17) at its distal end forming a pair of jaws (15, 16) with converge towards a mouth at the distal end of the handle. The head (3) has a slot (34) at its proximal end forming a pair of jaws (32, 33) and these also converge in a similar manner. The handle is planar and has a central through hole (20), and the head has a planar part with a central through hole (35). The user grasps the handle and the head by different hands, mutually rotates the handle and the head about their longitudinal axes, pushes the handle and the head together with the jaws of each engaging opposed surfaces of the other and continues this action until the jaws snap fit in the holes (20, 35) of the other part. The assembled utensil is robust due to the strength of engagement of the handle and the head and that it extends in mutually perpendicular directions.

Description

Introduction

[0001] The present invention relates to utensils which are provided as part of food products to allow convenient consumption of the food.

[0002] It is known to provide such utensils of fibre-based materials such as wood, card, paper or moulded fibre, which are therefore biodegradable, renewable and do not contribute to plastics waste. An example is described in US1521768 (Herrmann). In this example a spoon is provided as a paper blank with fold lines to allow mutual rotation of sides to convert the blank from two dimensions to three dimensions with additional strength and conforming to the shape of a spoon bowl. Other examples of approaches are described in US9869575 (Ecotensil) and US3931925 (R. Stanley), and GB2281689. JPH0434971U describes a two-part constructible utensil according to the preamble of claim 1. This utensil is of plastics material, the parts fitting together with projections snap fitting into holes.

[0003] The present invention is directed towards providing an improved utensil in terms of its manner of packaging with the food product and also in its utility as a spoon, spork or fork.Summary of the Invention

[0004] The invention provides a constructible utensil as set out in claim 1.

[0005] The invention also provides a convenience food product comprising a food container and the claimed utensil with the parts separate and one part overlying the other.

[0006] Preferably, the utensil is stored in a recess in a base of the container, or in an over-lid cavity.

[0007] The invention also provides a method of assembling the claimed utensil the method comprising grasping the parts by different hands, mutually rotating them about their longitudinal axes, pushing the parts together with the jaws of each part engaging opposed surfaces of the other part and continuing this action until the jaws snap fit in the recesses.Detailed Description of the Invention

[0008] The invention will be more clearly understood from the following description of some embodiments thereof, given by way of example only with reference to the accompanying drawings in which: Fig. 1 is a perspective view of a constructible spoon when wrapped for a food product container, and Fig. 2 is a similar view of a constructible fork; Fig. 3 is a perspective view of the spoon with the two parts separated, showing features of the spoon parts in detail; Fig. 4 is a perspective view showing the two parts being brought together, and Fig. 5 shown them when together as a constructed spoon ready for use; and Figs. 6, 7, and 8 are views similar to Figs. 3, 4, and 5 of the fork.

[0009] Referring to Fig. 1 a constructible utensil is in this example a spoon 1, having a handle part ("handle") 2 and a spoon head part ("head") 3. When packaged on a substrate 5 the handle 2 overlies the head 3 in a compact arrangement with a low profile. This is helped by the fact that the handle and the proximal end of the head are planar, and with the handle overlying the concave spoon surface the packaged height is only about 7.5 mm in this example. In general, it is preferred that the packaged thickness does not exceed 10mm, and it is preferred that the thickness of the material in each part does not exceed 2mm, preferably less than 1mm.

[0010] The overall dimensions of the parts 2 and 3 are in this example: the spoon head 3 is c. 66 mm in length and the handle is c. 60 mm in length. In another example these dimensions are 67.5 mm and 65.5mm, respectively. The lengths can be as desired and as space allows.

[0011] Fig. 2 shows an alternative constructible utensil, in this case a fork 100 packaged into a substrate 105. This has the handle 2 and a fork head 103 having an overall configuration which differs from the spoon 1 only at the distal end of the head.

[0012] Both utensils are entirely of wood material, in this case birch wood. In other examples the material may be different, such as bamboo, card, paper, or moulded fibre. Hence, they are completely biodegradable. As is explained in more detail below they have the major benefits of being compact when packaged because they are in two parts overlying each other with a low profile, and being long enough for convenient use when constructed, and also being strong because they are of wood material and the manner of inter-engagement of the handle and head, as described in more detail below.

[0013] A utensil of the invention may be of any type, including a knife or chopstick for example.

[0014] Referring to Figs. 3 to 5 the spoon 1 is described in more detail. The handle 2 is of planar wood configuration, having a planar body 10 with a proximal end 13 and a distal end 14 and the longitudinal direction is defined as that extending between the proximal and distal ends. The proximal end 13 end has a convex curved edge. Side edges 11 and 12 of the handle converge with a narrowing taper towards the distal end 14. The latter has a cut-out slot 17 extending in the longitudinal direction so that the planar body 10 forms a pair of jaws 15 and 16. Due to the shape of the slot 17 these jaws converge distally to form a narrow mouth of the slot 17. The handle 2 also has a central through-hole 20 proximally of the jaws 15 and 16 and on the longitudinal axis, aligned with the slot 17.

[0015] The spoon head 3 has a proximal portion 30 which is planar, having the same thickness as the handle 2. Its proximal end 30 has a cut-out slot 34 forming opposed jaws 32 and 33, which converge proximally with a similar taper angle as the jaws 15 and 16 of the handle. The slot 34 has the same dimensions as the slot 17 of the handle. The head proximal portion 30 also has a through-hole 35 which is distal from the jaws 32 and 33 and spaced from them on the longitudinal axis of the head 3 by the same extent as the hole 20 is from the jaws 15 and 16 of the handle. The distal end 31 of the head 3 is of conventional spoon shape having a concave portion 40.

[0016] Fig. 4 shows that, in use after removal from the packaging substrate 5, the handle and the head are orientated at a mutual angle of 90° about the longitudinal axes and pushed together so that the slots 17 and 34 engage each other. This pushing action is continued against the friction resistance of the ends of the jaws 15 / 16 and 32 / 33 rubbing against the planar surfaces of the other part. This resistance continues until the leading ends of the jaws snap-fit into the hole 20 / 35 of the other part. This informs the user that the parts 2 and 3 have fully engaged. In this position the inner edges of the jaws engage the planar surfaces of the opposed part, and this together with the snap-fitting engagements provides sufficient strength of engagement for the two parts to form a unitary spoon suitable for use with the food of the package. As is clear from Fig. 5 there is a considerable degree of overlap and the 90° mutual angle helps to provide anti-bending strength in use.

[0017] Referring to Figs. 6, 7, and 8 the fork 100 parts 2 and 103 are similar to the parts 2 and 3, except for the fork head 104 of the head part 103. Like parts are given the same reference numerals, and assembly of the fork 100 is the same as that of the spoon 1.

[0018] It will be appreciated that the utensil of the invention may take any suitable form, the distal end of the head being shaped as desired to suit the use.

[0019] A utensil of the invention is compact when packaged, can be easily assembled, and has excellent strength due to the manner of engagement of the parts. It is particularly advantageous that the material is of wood due to its biodegradable nature and strength and suitability for snap-fitting engagement as described. The overall length of the assembled utensil is nearly double that of the parts. Importantly, the jaws and the cut-out slots give the utensil particular strength whereby the handle remains firmly attached to the head while in use. The two corresponding slots also ensure strong vertical and horizontal strength

[0020] The invention is not limited to the embodiments described but may be varied in construction and detail within the scope of the claims, as would be readily understood by a person of ordinary skill in the art. However, it is particularly beneficial that the slots (as shown for the slots 17, 24) narrow gradually towards their mouths because this gives a large extent of surface contact for firm inter-engagement.

[0021] Also, at least one part may have material which extends beyond the end of the mouth of the slot, possibly to provide additional stability.

[0022] The jaws of any one pair may be of different length so that they engage the other part at different longitudinal positions. Other variations are material and overall length shape of the cutlery item. The composition may be fibre moulded pulp made from wood or bagasse.
