Abstract

The degradable frame product of the paper lunch box comprises a box body and a box cover which are mutually buckled, wherein an outer convex frame is arranged at the edge of the upper end of the box body, an inner concave degradable groove frame is arranged at the position, corresponding to the outer frame, of the inner wall of the box cover, and the degradable groove frame and the outer frame are mutually buckled; the degradable groove frame is formed by injection molding of biodegradable materials, a plurality of convex points are arranged on the groove wall of the degradable groove frame at intervals, and the convex points are used for tightly buckling the box cover on the box body. The utility model solves the problem that the box body and the box cover of the existing paper lunch box are not tightly buckled, and after the meal with soup is put into the paper lunch box, the meal is not easy to leak, thereby improving the dining experience of customers.

Description

Degradable frame product of paper lunch box

Technical Field

The utility model relates to the technical field of paper containers, in particular to a degradable frame product of a paper lunch box.

Background

In recent years, plastic pollution is becoming more serious, and plastic restrictions are promulgated in various places, so that the use of disposable plastic products, such as takeaway lunch boxes which are used in large quantities at present, is restricted or prohibited. Beverage cups, and the like. The development of paper product containers and fully biodegradable materials is increasing, the application range is expanding continuously, and the paper product containers and the fully biodegradable materials gradually replace the traditional plastics in the field of disposable tableware.

At present, the fully biodegradable material (such as PLA) has gradually replaced disposable PP plastic containers in a small amount, but due to the high price of the material and the difficulty of processing and forming processes, the material has great difficulty in being put on the market, and particularly the material is not cost-effective. However, although the paper lunch box is high in cost performance, it does not have good sealing performance when sealed with a lid, and the soup is likely to leak when slightly shaken in the state of containing the soup, so that few people are willing to use a paper container as the container in the state of containing the soup.

SUMMERY OF THE UTILITY MODEL

In order to overcome the problems, the utility model provides a paper lunch box degradation frame product.

The technical scheme adopted by the utility model is as follows: the degradable frame product of the paper lunch box comprises a box body and a box cover which are mutually buckled, wherein an outer convex frame is arranged at the edge of the upper end of the box body, an inner concave degradable groove frame is arranged at the position, corresponding to the outer frame, of the inner wall of the box cover, and the degradable groove frame and the outer frame are mutually buckled; the degradable groove frame is formed by injection molding of biodegradable materials, a plurality of convex points are arranged on the groove wall of the degradable groove frame at intervals, and the convex points are used for tightly buckling the box cover on the box body.

Preferably, the shape of the salient points is hemispherical, truncated cone, truncated pyramid or litchi rind pattern.

Preferably, the plurality of salient points are uniformly distributed on the outer groove wall of the degradable groove frame.

The utility model has the beneficial effects that:

(1) the degradable slot frame is made of biodegradable materials through injection molding, the problem that the existing paper lunch box body is untight with the box cover is solved, after rice and dishes with soup are placed in the paper container, seepage is not prone to occurring, dining experience of customers is improved, and the degradable slot frame is strong in practicability and has popularization value.

(2) The degradable groove frame is made of a fully biodegradable material (PLA material, PBS material or PFM.

(3) The biodegradable material is expensive, and compared with the environment-friendly lunch box which is completely made of the biodegradable material through injection molding, the cost of only injection molding the degradable groove frame on the box cover is low, and the market competitiveness is improved.
