Novel packaging box and manufacturing technology thereof

Abstract

The invention relates to a novel packing case and the manufacturing process thereof, which is characterized in that the novel packing case comprises an upper casing body and a lower casing body which are oppositely covered, and an elastic tensioning diaphragm which can elastically clip objects when the casing bodies are oppositely covered is respectively adhered to the upper casing body and the lower casing body by adopting UV adhesive. The novel packing case has the advantages that the structure is simple, the design is reasonable, is in favor of simplifying the production processes, reducing the production cost and re-utilization. Due to the advantages of the UV adhesive, the elastic tensioning diaphragm which is adhered by adopting the adhesive has the significant advantages of high bonding strength, high speed and high degree of automation, etc.

Description

Technical field: [0001] The invention relates to a novel packaging box applied to fragile items and a manufacturing process thereof. Background technique: [0002] There are several types of packaging boxes currently used for packaging fragile items, especially those described in FR2239878, US2837208, US2681142, and EP0557804. All of these boxes feature a layer of heat-shrinkable plastic film to wrap around the item to be packed. These boxes suffer from a number of disadvantages, the main ones being: Once the items have been placed, the box must be heated to cause shrinkage of the film layers to secure the items, and the difficulty of securing these layers of heat-shrinkable plastic film to the rigid components of the box At the same time, the items wrapped between the layers of heat shrinkable film will also bear strong pressure. [0003] Document FR2239878 also describes a box in which the object to be protected is fixed in the space formed by two sheets. For this kind ...

Problems solved by technology

These boxes suffer from a number of disadvantages, the main ones being: Once the items are placed, the box must be heated to cause shrinkage of the film layers to secure the items, and the difficulty of securing these layers of heat-shrinkable plastic film to the rigid components of the box It is very large, and the items wrapped between the heat shrinkable film layers will also bear strong pressure

[0007] Finally, in the document EP0557804, the box includes a box bottom and a box top and some devices for fixing the objects in the space formed when the box bottom and box top are joined, the box bottom and box top have a slot on the edge of the opening; The opening is filled with a film layer, and the edge of the film layer is fixed in the groove with a wire or a snap ring." Although these packaging boxes use a wire or a snap ring to fix the edge of the film layer in the channel on the edge of the box frame to achieve item security. Fixed, but due to the design of the box structure (the channel structure of the fixed wire or the snap ring), when the fixed wire or snap ring is pulled by the film layer for many times, the film layer is easy to loosen, so that it cannot Better fixed objects are not conducive to repeated use. In addition, the frame thickness of the designed box body is required to be thicker, and the channel design accuracy is higher, which increases the manufacturing cost.
