Paper cutlery box

Technical Field

The utility model relates to a disposable cutlery box technical field especially relates to a paper cutlery box.

Background

The disposable lunch box is the main container for taking-out box lunch. Previous cutlery boxes were heavily plastic. Plastic meal boxes are low cost and have been widely used for many years. In recent years, plastic pollution has become more serious, and disposable lunch boxes have been changed from plastic lunch boxes to environment-friendly lunch boxes, which mainly include paper lunch boxes, wood lunch boxes, degradable lunch boxes, and the like.

At present, the commonly used paper lunch box comprises a paper box body and a plastic upper cover or a paper upper cover, and when the paper lunch box is used in daily take out, a plurality of paper lunch boxes need to be stacked together for carrying. The plastic upper cover or the paper upper cover adopted by the common paper lunch box is soft, and when the food contained in the paper lunch box is heavy, the upper cover of the lower lunch box is damaged because the upper cover cannot bear the weight of the upper stacked lunch box; in addition, the utility model is easy to slip and turn on one side during the takeaway transportation process; so few people are willing to implement paper lunchboxes to carry heavier food.

Disclosure of Invention

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

The utility model adopts the technical proposal that: a paper lunch box comprises a paper box body and a box cover which are mutually covered, wherein the upper edge of the paper box body is provided with an outward turned edge, the cross section of the turned edge is in a shape of a major arc, and the middle position of the turned edge is an arc top which protrudes outwards; the bottom surface of the paper box body is concave inwards to form a step surface, and the lower edge of the paper box body is used as a supporting leg to be supported on the paper lunch boxes stacked below;

the box cover comprises a paperboard and a frame, the outer edge of the paperboard is connected with the frame formed by injection molding of a biodegradable material, the frame is provided with a side wall perpendicular to the paperboard and a top surface parallel to the paperboard, and the inner side of the side wall of the frame is provided with a raised clamping rib; the distance between the end part of the clamping rib and the side wall of the paper box body is slightly smaller than the distance between the arc top and the side wall of the paper box body, and the clamping rib presses the arc top of the turned edge to elastically deform and is clamped and hooked at the lower part of the arc top of the turned edge in the buckling process; the inboard inside extension of frame top surface is provided with the mesa, and the mesa is located the below of paper box body supporting legs, is equipped with convex spacing step on the mesa, and spacing step encircles and sets up around the paper box body and restrict paper box body horizontal displacement.

Further, the inner angle of the frame is circular arc, and the horizontal length between two endpoints of the circular arc is greater than, equal to or less than the vertical height between two endpoints of the circular arc.

Further, the outer wall of the side wall of the frame is an inclined plane, and the inclined direction of the inclined plane is inclined outwards relative to the vertical direction from top to bottom.

Furthermore, the inner surface of the paper box body and the lower surface of the paper board are both provided with a full biodegradable spray film or a full biodegradable spray film.

Furthermore, a handle convenient for taking the box cover is arranged on the frame.

Furthermore, the top surface of the frame is provided with a plurality of through holes which are distributed at intervals continuously, and the hole patterns of the through holes are triangular, circular, square, rectangular or polygonal. The utility model has the advantages that:

(1) the problem that when a plurality of paper lunch boxes are stacked, the weight of the paper lunch box above the paper box cover cannot be supported by the paper board in the paper box cover, and the box cover is damaged is avoided; and the condition that a plurality of paper lunch boxes slip and turn on one side in the conveying process.

(2) The frame, the biodegradable film and the spray film are all made of biodegradable material (PLA material, PBS material or PFM.BSR material), and the biodegradable material, the paper lunch box and the paperboard can be degraded in nature and respond to environmental protection policies.

(3) The inner angle of the frame is arc-shaped, stress is dispersed, and stress concentration is avoided, so that the risk of frame fracture caused by injection molding of the biodegradable material is reduced. The horizontal length between two end points of the circular arc shape is greater than, equal to or less than the vertical height between two end points of the circular arc shape. The leakage-proof performance is further increased by matching the radian of the turned edge as much as possible.

(4) The biodegradable material is expensive, and the fully biodegradable frame is only injection molded on the outer edge of the paperboard, so that the cost is low, and the market competitiveness is improved.

(5) The frame is provided with a plurality of through holes, so that the biodegradable material can be saved, and the appearance is attractive.
