Method for manufacturing packaging box cover and packaging box cover manufactured by same

Abstract

The invention provides a method for manufacturing a packaging box cover and the packaging box cover manufactured by the same. The method comprises the following steps of: a step 1 of providing a lateral plate core board and a cover board; a step 2 of forming a plurality of section parts corresponding to the periphery of the cover board on the lateral plate core board; a step 3 of pasting lateral plate paper on the surface of the lateral plate core board to form a lateral plate body, ensuring the lateral plate paper to extend out of one edges of the section parts to form connecting parts so as to form a lateral plate with the lateral plate body and the connecting parts connected onto the lateral plate body, and forming a plurality of lateral plate units which are sequentially connected and can be relatively bent at the corresponding section parts of the lateral plate body; and a step 4 of placing the edges of the lateral plate units, which correspond to the cover board, vertically to the cover board, connecting the lateral plate units end to end, respectively adhering the connecting parts onto the cover board and forming the packaging box cover with an opening. The packaging box cover has a simple structure, is convenient to manufacture and is beneficial to storage in the off-season of production.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a method for manufacturing a packaging box cover and the manufactured packaging box cover. Background technique [0002] With the development of the economy, packaging boxes have been extended to the outer packaging of food, cosmetics, stationery decorations and other fields. The manufacturing process of existing packaging boxes such as heaven and earth boxes is generally to cut a whole cardboard into a predetermined shape, and then set the folding line, and fold along the folding line to form a bottom box, and the cover box covered on the bottom box is made in the same way as the bottom box. However, since the existing heaven and earth box forms a fixed size volume after the production is completed, it must occupy the same size space regardless of whether there are items placed in it. In the storage and transportation of the packaging box, it will cause waste of space and incr...
