Detailed Description

In order to make the technical means, creation features, achievement of objects and effects achieved by the present invention easy to understand, the following embodiments are specifically described with reference to fig. 1 to 6 for a kitchen having a plurality of cooktops.

Referring to fig. 1, a split structure schematic diagram of an environment-friendly cutlery box is shown; referring to fig. 2, a bottom view structure of the environment-friendly cutlery box is shown; and figures 3 and 4 are perspective views of the case body in the environment-friendly cutlery box; and fig. 5 and 6 are perspective views of the cover body in the environment-friendly cutlery box.

As shown in fig. 1 to 6, the environment-friendly cutlery box provided by the invention comprises a box body 1 made of paper materials and a cover body 2 matched with the box body 1 in shape, wherein a plurality of folded edges 3 are formed by outwards folding the outer edge of the box body 1, the cover body 2 is covered on the box body 1 to seal the upper opening of the box body 1, and the folded edges 3 are further folded under the compression of the inner side wall of the cover body 2 and clamp the inner side wall of the cover body 2 by the outwards self-tension of the paper folded edges 3.

In the above technical scheme, the whole box body 1 is made by paper material, and is comparatively environmental protection, for the box body 1 of making by plastics at present more accords with the sustainable development's of current popularization concept, and box body 1 and lid 2 easy dismounting, simple structure is succinct reliable and use convenient, is difficult for breaking away from each other between box body and the lid. In addition, the paper material is mainly hard paper board and is made by pressing paper pulp, but the paper material can also be a material prepared by mixing various additives into the paper pulp, and the material is determined according to the production and use requirements.

In a preferred embodiment, a plurality of positions on the outer side wall of the cover 2 are recessed inwards and a plurality of protrusions 22 are formed on the inner side wall of the cover 2 in a protruding mode, and the protrusions 22 clamp the folded edges 3, so that the connecting structure of the cover 2 and the box 1 is more stable. Further, a concave surface 21 is formed on the upper top surface of the cover 2 by recessing inwards, and a circle of clamping groove 23 is formed on the inner top surface of the cover 2, and the upper edge of the box 1 is clamped in the clamping groove 23 during installation. So that the connection structure of the case 1 and the cover 2 is more stable. As is evident, as shown in fig. 2, 5 and 6, the shape of the clamping groove 23 matches the shape of the case 1.

In this embodiment, the overall cross-sectional shapes of the case 1 and the cover 2 are rectangular, and four edges of the case 1 are respectively folded to form a folded edge 3. In addition, the fold 3 shown in fig. 3 is in a state that the fold 3 is folded outwards by 90 degrees with respect to the edge of the case 1 when the cover 2 is not attached, while the fold 3 shown in fig. 4 is in a state that the fold 3 is folded outwards again by 60 degrees with respect to the edge of the case 1 when the cover 2 is attached, but this folding angle is determined according to the outer dimension of the case 1 and the dimension of the side wall of the edge of the cover 2, and the specific angle may be changed according to the actual application, and the above-mentioned outward folding refers to the direction with respect to the inside of the case 1, i.e., the direction that defines the inside facing the case 1 is inwards, and the direction that deviates from the inside of the case 1 is outwards, as shown in fig. 3 and 4.

As a further preferred embodiment, as shown in particular in fig. 2 and 3, the central portion 31 of the outer edge of each flap 3 extends outwards in a wavy line and shoulders 32 are formed on both sides of the outer edge of the flap 3, respectively, to rest against the lugs 22. On the one hand, the utility model is more beautiful, and on the other hand, the abutting effect of the folded edge 3 and the convex block 22 is better. Further, the number of the protrusions 22 on each side of the cover 2 is two, and the protrusions are opposite to the shoulder 32.

In a preferred embodiment, as shown in fig. 1, 3 and 4, two triangular paper sheets 11 are adhered to two opposite inner side walls of the case 1, respectively, and four paper sheets 11 are formed by folding over the other two opposite inner side walls. Namely, in the manufacturing process of the box body 1, a plane paper mold is firstly manufactured, the plane paper mold comprises a rectangular bottom surface, four rectangular side surfaces positioned at the periphery of the bottom surface, folded edges 3 connected to the outer edge of each side surface through crease lines, paper sheets 11 connected to the left and right sides of two opposite side surfaces, then four side surfaces are folded relative to the bottom surface, the four side surfaces are respectively adhered to the adjacent side surfaces by using the four paper sheets 11 to connect the four side surfaces into a whole, and the four folded edges 3 are folded outwards to form the box body 1 as shown in fig. 3. In addition, in the present embodiment, the cover 2 is made of transparent material, specifically PP or PE material, but paper may be used, but the cost is relatively high, and the invention is not limited thereto.

As a further preferred embodiment, as shown in fig. 2 and 5, the lower edge of the cover 2 is further formed with a ring of flanges 24 extending outwards, so that the cover 2 is more convenient and more beautiful to open. In addition, the case body 1 and the cover body 2 are all integrated, and the inner sides of the case body 1 and the cover body 2 are respectively formed with a cavity for accommodating food, and the structure is basically the same as the existing shape, so that the description is omitted. The cavity in the box body 1 is small at the bottom and large at the top, and the cavity in the cover body 2 is small at the top and large at the bottom.

The foregoing description of the preferred embodiment of the invention is merely illustrative of the invention and is not intended to be limiting. It will be appreciated by persons skilled in the art that many variations, modifications, and even equivalents may be made thereto without departing from the spirit and scope of the invention as defined in the appended claims.
