Description

Cardboard for buffer type corrugated case

Technical Field

The utility model relates to the technical field of packaging, in particular to a paperboard for a buffer type corrugated case.

Background

The traditional paperboard for the corrugated case with the buffering function has the limitation of the buffering function. The corrugated board is mostly composed of face paper, lining paper and corrugated paper arranged between the face paper and the lining paper, and the front end face and the rear end face of the corrugated paper are bonded and fixed, so that the corrugated paper does not displace when impacted, and only the bending ribs on the corrugated paper are used for moderately deforming, so that a certain buffering effect is achieved, and the overall effect is poor. Accordingly, the utility model provides a paperboard for a buffer type corrugated case.

Disclosure of Invention

The utility model aims to overcome the defects in the prior art and provide a buffer type paperboard for corrugated cartons.

In order to solve the technical problems, the aim of the utility model is realized as follows: the utility model relates to a paperboard for a buffer type corrugated case, which comprises facial tissues and lining papers, wherein a first corrugated paper adhered to the facial tissues and a second corrugated paper adhered to the lining papers are arranged between the facial tissues and the lining papers;

a plurality of first U-shaped bulges are formed on the first corrugated paper, and a first clamping groove is formed between every two adjacent first U-shaped bulges;

a plurality of second U-shaped bulges are formed on the second corrugated paper, and a second clamping groove is formed between every two adjacent second U-shaped bulges;

the first U-shaped bulge is embedded in the second clamping groove, and the second U-shaped bulge is embedded in the first clamping groove;

the two sides of the first U-shaped bulge are respectively provided with a first beam piece close to the end part, the wall of the second clamping groove is provided with a first beam hole for the first beam piece to slide back and forth, and the length extension direction of the first beam hole is the same as the depth extension direction of the second clamping groove;

the two sides of the second U-shaped bulge are respectively provided with a second beam piece close to the end part, the groove wall of the first clamping groove is provided with a second beam hole for the second beam piece to slide back and forth, and the length extension direction of the second beam hole is the same as the depth extension direction of the first clamping groove.

In summary, the utility model has the following beneficial effects: the two layers of corrugated paper capable of moving relatively are additionally arranged between the face paper and the inner paper, and are mutually embedded, so that the paperboard can be compressed in the thickness direction when being impacted, and after the impact force is removed, the original elasticity of the corrugated paper enables the corrugated paper to deform and reset, thereby achieving the effect of buffering and releasing the force, and the paperboard has perfect overall functions and strong practicability.

Detailed Description

In order that those skilled in the art will better understand the technical solutions of the present utility model, preferred embodiments of the present utility model will be described below with reference to specific examples, but it should be understood that these descriptions are only for further illustrating the features and advantages of the present utility model, and are not limiting the patent claims of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The utility model will be further described with reference to the drawings and preferred embodiments.

Example 1

Referring to fig. 1 and 2, the cardboard for a buffering type corrugated case according to the present embodiment includes a face paper 10 and an inner paper 20, wherein a first corrugated paper 30 adhered to the face paper and a second corrugated paper 40 adhered to the inner paper are disposed between the face paper 10 and the inner paper 20;

a plurality of first U-shaped protrusions 31 are formed on the first corrugated paper 30, and a first clamping groove 32 is formed between two adjacent first U-shaped protrusions 31;

a plurality of second U-shaped protrusions 41 are formed on the second corrugated paper 40, and a second clamping groove 42 is formed between two adjacent second U-shaped protrusions 41;

the first U-shaped protrusion 31 is embedded in the second clamping groove 42, and the second U-shaped protrusion 41 is embedded in the first clamping groove 32;

the two sides of the first U-shaped protrusion 31 are respectively provided with a first beam piece 33 near the end, the groove wall of the second clamping groove 42 is provided with a first beam hole 43 for the first beam piece to reciprocally slide inside, and the length extension direction of the first beam hole 43 is the same as the depth extension direction of the second clamping groove 42;

the two sides of the second U-shaped protrusion 41 are respectively provided with a second beam piece 44 near the end, the groove wall of the first clamping groove 32 is provided with a second beam hole 34 for the second beam piece 44 to reciprocally slide therein, and the length extension direction of the second beam hole 34 is the same as the depth extension direction of the first clamping groove 32.

In the present embodiment, since the first bundle piece 33 is provided in the first bundle hole 43 and the second bundle piece 44 is provided in the second bundle hole 34, the first corrugated paper 30 and the second corrugated paper 40 fitted to each other are connected to each other, and separation is prevented. When the end surface of the cardboard is impacted, the gap between the face paper 10 and the inner paper 20 is reduced, so that the first U-shaped protrusion 31 on the first corrugated paper 30 further stretches into the second clamping groove 42, the second U-shaped protrusion 41 on the second corrugated paper 40 further stretches into the first clamping groove 32, the two clamping grooves are moderately expanded and deformed, the buffer release force effect is achieved, after the impact force is removed, the first clamping groove 32 and the second clamping groove 42 are deformed and reset, the first bundle piece 33 correspondingly slides in the first bundle hole 43, the second bundle piece 44 correspondingly slides in the second bundle hole 34, the reset is realized, and the buffer release force is completed.

The two layers of corrugated paper capable of moving relatively are additionally arranged between the face paper and the inner paper, and are mutually embedded, so that the paperboard can be compressed in the thickness direction when being impacted, and after the impact force is removed, the original elasticity of the corrugated paper enables the corrugated paper to deform and reset, thereby achieving the effect of buffering and releasing the force, and the paperboard has perfect overall functions and strong practicability.
