Paper box used without tape and die-cutting type-setting method thereof

Abstract

The invention discloses a paper box used without a tape and a die-cutting type-setting method thereof. The paper box sequentially comprises a first side board, a second side board, a third side boardand a fourth side board which are folded and connected, and the first, second, third and fourth side boards can be folded into form accommodation space; a first upper main sealing plate and a first lower main sealing plate are arranged on the two sides of the first side plate through folding, a second upper auxiliary sealing plate and a second lower auxiliary sealing plate are arranged on the twosides of the second side board through folding, a third upper main sealing plate and a third lower main sealing plate are arranged on the two sides of the third side board through folding, and a fourth upper sealing plate and a fourth lower sealing plate are arranged on the two sides of the fourth side board through folding; an upper protruding portion which can be connected with the third upper main sealing plate is arranged on the first upper main sealing plate, and the central line of the first upper main sealing plate and the central line of the upper protrusion portion are colinear; a lower protrusion portion which can be connected with the first lower main sealing plate is arranged on the third lower main sealing plate. The invention further provides a die-cutting type-setting methodof the main paper box used without the tape.

Description

technical field [0001] The invention relates to the technical field of carton production, in particular to a tape-free carton and a die-cutting typesetting method thereof. Background technique [0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated boxes and single-layer cardboard boxes. Usually, cartons are sealed with adhesive tape. Although the adhesive tape has a good sealing effect, it needs to be equipped with sealing tools such as adhesive tape and scissors. The sealing process is laborious, and the adhesive tape also increases the sealing cost. , and it is not conducive to sorting and recycling. [0003] see figure 1 and figure 2 . figure 1 It is a structural schematic diagram of a flat mouth carton in the prior art. figure 2 It is a structural schematic diagram of a fully covered carton in the prior art. [0004] The existing flat-mouthed cartons on the market cannot be sealed without tape, and hol...

AI Technical Summary

Problems solved by technology

[0004] The existing flat-mouthed cartons on the market cannot be sealed without tape, and the hollowed out position is prone to appear after sealing, resulting in an imprecise seal

The tape-free cartons are full-covered cartons, and the paper used is 1.5 times that of ordinary flat-mouthed cartons. According to the larger the box type, the more materials will be used, which will not achieve the actual purpose of environmental protection. It will only lead to more paper consumption and cause more damage. There is a lot of waste, and the carton is more expensive due to more materials
