Description

Exempt from sticky tape auto-lock carton

Technical Field

The utility model belongs to the technical field of the packing carton, a exempt from sticky tape auto-lock carton is related to.

Background

In present product packaging, adopt carton packing usually more, especially at the very big today of express delivery logistics demand, for the convenience carton encapsulation, adopt plastic tape to seal usually. The use of the adhesive tape not only increases the cost of sealing the box, but also causes environmental pollution because the plastic adhesive tape is difficult to be decomposed by soil due to special materials after being used and discarded. In addition, when the carton is unsealed, a sharp auxiliary tool is usually needed to be used for unsealing, which is very inconvenient and dangerous.

If no adhesive tape is used for sealing the box, a non-adhesive tape carton is designed, for example, a utility model of the non-adhesive tape carton with the application number of 201821408300.3 published by Chinese patent, the carton comprises a box body in a square shell shape, the upper parts of two opposite side plates of the box body are respectively connected with a sealing cover top surface through creases, the upper parts of the other two opposite side plates of the box body are respectively connected with a reinforced top surface through creases, the top edge at the upper end of the sealing cover top surface is in a Z-shaped structure, the top edges of the two sealing cover top surfaces are arranged in a mirror image manner, the top edges of the sealing cover top surfaces respectively comprise an upper top edge with a higher relative position and a lower top edge with a lower relative position, and the lower top edge is connected with a limiting part through a crease, the lower part of the rocking cover part and a side plate connected with the rocking cover part are respectively provided with a lock hole which is matched with each other, the reinforcing top surface and the sealing cover top surface are turned inwards, and the sealing cover top surface is overlapped and pressed on the reinforcing top surface to form a box cover.

Just above-mentioned exempt from under the not destroyed prerequisite of sticky tape carton just can open, factor of safety is low and causes the overall theftproof effect of carton poor.

In order to solve the technical problems, the design of the adhesive tape-free self-locking carton is urgent, the carton is required to be damaged and stolen and can be immediately seen from the appearance, and meanwhile, the carton is firm and anti-dismantling, so that the safety and reliability in the transportation process can be improved.

SUMMERY OF THE UTILITY MODEL

The utility model aims at having the above-mentioned problem to current technique, provided an exempt from sticky tape auto-lock carton, it is dead to pack the good back auto-lock, has avoided the use of sticky tape, has still strengthened the fastness of carton moreover.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides an exempt from sticky tape auto-lock carton, is including the box that is square shell form, and the box is including consecutive roof inside, left side board, bottom plate, right side board, outer roof, both ends are connected with terminal surface gusset plate one through the crease respectively about the left side board, and the lower extreme is connected with terminal surface gusset plate two through the crease respectively on the right side board, and the lower extreme is connected with outer end plate through the crease on the bottom plate, and outer end plate outer end still is connected with interior end plate through the crease, and interior end plate both sides all are connected with the curb plate reinforcing plate through the crease, its characterized in that, bottom level is provided with square backing plate in the box, the crease department of roof inside opens there is the main lockhole, and the vice spring bolt of main lockhole internal connection, outer roof outer end is connected with the main spring bolt that inserts in the main.

Further, an arc-shaped tearing strip is arranged on the outer top plate and surrounds the main lock tongue. When the carton needs to be disassembled, the tearing tape is torn, the outer top plate is divided into two parts, and articles in the carton can be taken out.

Furthermore, the main bolt and the auxiliary bolt are the same in shape and respectively comprise a square main body and locking parts which are located on two sides of the main body and are fan-shaped and prevent the main body from being withdrawn, and the locking parts are connected with the main body through folds. The lock part is bent inwards during insertion, and the lock part returns to the original position after insertion to form inverted tooth clamping.

Furthermore, fan-shaped lug plates are connected to the upper end and the lower end of the outer top plate through creases.

Furthermore, the outer side of the inner end plate is connected with a folding edge through a crease.

Furthermore, the outer side of the side plate reinforcing plate is connected with a folding edge through a folding line.

Compared with the prior art, this exempt from sticky tape auto-lock carton has following advantage:

1. the locking and anti-dismantling are realized through the lock tongues, the use of adhesive tapes is avoided, the box sealing cost is saved, the environmental pollution is reduced, the good effect of protecting the environment is achieved, and meanwhile, the design has a good anti-theft function and is beneficial to popularization in the actual use of the market;

2. the tearing tape is arranged on the carton, so that the carton can be destructively opened without using a sharp auxiliary tool, and the harm of the sharp auxiliary tool to the articles in the carton and a user is avoided;

3. the bottom plate is matched with the base plate to form a double layer, the end plate comprises an inner end plate and an outer end plate which are also double layers, and a side plate reinforcing plate is also arranged in the left side plate or the right side plate which are also double layers, so that the whole box body is firmer and more firm and is not easy to flatten.
