Combined containing box and manufacturing device thereof

Abstract

The invention relates to a combined containing box. The box comprises a plurality of independent containing boxes (11), each independent containing box is formed by a plastic plate (L) containing at least one PET layer (polyethylene glycol terephthalate), the independent containing boxes (11) are connected through a connecting bridge (12), and the connecting bridge is provided with an upper pre-cutting line (13) and a lower pre-cutting line (14) which are used for disconnecting the connecting bridge. The upper pre-cutting line (13) and the lower pre-cutting line (14) are parallel in the horizontal direction, are transversely spaced and are mutually spaced in the vertical direction, so that the situation that the characteristics of the PET layer are changed when the compression heat is toohigh is avoided, and meanwhile, the connecting bridge can be tidily disconnected by rotating the containing box at the positions of the upper pre-cutting line and the lower pre-cutting line. The invention further provides a device for manufacturing the combined containing box.

Description

technical field [0001] The invention relates to the field of manufacturing combined storage boxes used in the food industry, in particular to storage boxes for packaging yogurt, custard, custard, jelly or similar foods. Background technique [0002] In the manufacture of container boxes in the food industry, single-layer or multi-layer boards made of plastic materials are usually used to make combined container boxes. These combined receptacles have a plurality of individual cavities or receptacles which are connected by connecting bridges arranged in the plastic sheet. [0003] Once each individual container is filled and closed, each container will be subjected to a cutting operation in which the shape of a part of the structure of the container is machined and a pre-cutting operation in which a pre-set is placed on the connecting bridge. A cutting line, the pre-cutting line will be used to realize the subsequent breaking and separation of each independent container of th...

AI Technical Summary

Problems solved by technology

This flattening process will increase the temperature in the central area of ​​the material to be cut, causing the molecular structure of the PET material to change and become a more elastic material, thus increasing the classic hinge effect of PET, therefore, in order to break the connecting bridge And to separate each containing box, the containing box must be rotated in opposite directions at the same time, resulting in the separation of the containing box will leave an irregular surface in the pre-cut area, posing a threat to consumers
