Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention so that the technical solution of the present invention can be more easily understood and grasped, and should not be construed as limiting the present invention.

Example 1:

referring to fig. 1, 2 and 3, a PLA lunch box cover includes a cover body 1, where the cover body 1 includes a top cover portion 11, side edge portions 12, a flanging portion 13, bumps 14 uniformly distributed on the inner side of the flanging portion 13, and cover ears 15 located on the outer side of the flanging portion 13; the cover dome section 11 is provided with a first concave groove 111. The cover body 1 is of an integrated structure, and the adopted material is polylactic acid (PLA). The processing mode is thermoplastic and hot-press molding.

Through the aforesaid setting, bump 14's effect improves the inseparable degree of joint to the cutlery box edge, mode chucking cutlery box through bump 14, the multiple operation of polylactic acid PLA dining box lid of being convenient for on the one hand, in-process closing and opening many times, bump 14 and its structural strength on every side still can keep, be difficult for appearing droing or splitting, the effect of cover ear 15 is the opening of polylactic acid PLA dining box lid of being convenient for, the effect of first recess 111 is the structural strength who provides the region of placing and further improve top cap portion 11, high temperature is difficult for causing the deformation of top cap portion 11.

Example 2:

based on the embodiment 1, the salient points 14 are replaced by food-grade silica gel. The connection mode of the polypropylene material and the silica gel material is fixed by hot-pressing fusion, and can also be fixed by adopting natural glue. The salient points 14 are made of silica gel, food-grade silica gel is adopted, the safety is higher, and due to the elastic capacity of the silica gel, the effective deformation capacity is high, and the restoration can be realized.

Referring to fig. 4, the side portion 12 is made of flexible silicone, and a convex ring 121 is disposed inside the side portion 12. Set side portion 12 to flexible to can change the position of top cap portion 11, bulge loop 121's effect carries out the joint to the inboard of lid, thereby further improves the leakproofness, and this structure is convenient for use person's operation more easily in the mode of inboard joint, and the user can conveniently open polylactic acid PLA dining-table lid under sealed the condition.

The location of the flange 13 and the collar 121 forms a snug area 2 for the lid edge to receive. The flanging part 13 is positioned at the outer edge of the lunch box, and the flexible convex ring 121 structure can deform when approaching the lunch box, so that the lunch box is attached to the lunch box more, and the sealing performance is improved.

Referring to fig. 4 and 5, the side portion 12 has an "F" shape in cross section, and the protruding ring 121 protrudes into the side portion by a length L1 greater than a thickness L2. The side portion 12 supports the ceiling portion 11 in an initial state; when the top cover part 11 is pressed down, the second groove 3 is formed on the edge of the side part 12 and the top cover part 11, and the difference D1 between the outer diameter of the top cover part 11 and the inner diameter of the flanging part 13 is smaller than or equal to the thickness L2 of the convex ring 121. In the present embodiment, L1 is preferably 5mm, L2 is preferably 3mm, and D1 is preferably 2 mm.

With the structure, when the top cover part 11 falls, the top cover part 11 can also extrude the convex ring 121, and the convex ring 121 and the top cover part 11 extrude at the inner side of the lunch box to seal the opening of the lunch box from the inner side.
