Description

But dilatation formula corrugated box

Technical Field

The utility model belongs to the technical field of corrugated box, especially, relate to a but dilatation formula corrugated box.

Background

The corrugated paper board is made into the corrugated paper box through die cutting, indentation, box nailing or box gluing. Corrugated paper carton is a packaging product with the widest application, and the consumption is always the first of various packaging products. Corrugated paper boxes gradually replace transport packaging containers such as wooden boxes and the like with excellent service performance and good processing performance for more than half a century, and become the leading force of transport packaging. It not only protects the goods, is convenient for storage and transportation, but also beautifies the goods and publicizes the goods. The volume of the corrugated case which is generally used is fixed, and the volume cannot be changed according to the actual object capacity;

based on this problem, the bulletin number is: the chinese utility model patent of CN206255330U discloses a corrugated paper carton with variable volume, which makes the internal volume of the corrugated paper carton variable by the split design of side plates and bottom plate, and can change the volume of the corrugated paper carton according to the actual volume of the stored articles; however, when the corrugated case is used, the maximum volume of the corrugated case in a closed state is fixed, if the volume is further expanded, the upper cover needs to be erected to form more storage spaces, the four upper cover plates need to be glued by using adhesive tapes after the upper cover is erected, the required operation is more, the adhesive tapes need to be torn off when the corrugated case is restored after the volume is expanded, and the surface of the upper cover plate is easily damaged at the moment, so that the normal use of the corrugated case is influenced; there is therefore a need for improvements to existing corrugated boxes.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the technical problem that above-mentioned exists, provide a but dilatation formula corrugated box, reached and enabled the apron upwards to stand and realize the expansion of maximum volume, recover the effect that the in-process can not destroy corrugated box leakproofness simultaneously.

In view of this, the utility model provides a but dilatation formula corrugated box includes:

the box body is internally provided with an accommodating cavity, and the upper part of the box body is provided with four cover plates which can turn over to cover the accommodating cavity;

a clamping plate arranged on the cover plate;

the clamping seat is arranged on the side wall of the box body and can be detachably matched with the clamping plate;

wherein, the cardboard can make the apron keep the state of standing with the cassette cooperation.

In the technical scheme, under the condition of normal use, the accommodating volume of the corrugated case is the volume of the accommodating cavity, the opening and closing of the top opening of the accommodating cavity are realized by the four cover plates through overturning, and the accommodating cavity can be divided into a plurality of smaller accommodating spaces to be suitable for storing different articles; when the volume of the articles to be stored exceeds the volume which can be accommodated by the accommodating cavity, the four cover plates are turned upwards to enable the cover plates to be parallel to the side walls of the box body, the cover plates are in a standing state at the moment, then the cover plates are kept in the standing state through the matching of the clamping plates and the clamping seats, an expansion space is formed among the four cover plates, the space is communicated with the original accommodating cavity, and the volume which can accommodate the articles is expanded to the upper side walls of the cover plates at the moment; when the corrugated case needs to be restored in the follow-up process, the clamping plate and the clamping seat are disassembled, the four cover plates can be freely turned over, and the structure of the corrugated case cannot be damaged.

In the above technical scheme, further, the mounting groove has been seted up on the apron is close to the lateral wall of one side of box, the lateral wall sliding connection of cardboard and mounting groove.
