Description

Reinforced waterproof paper corner protector for paper packaging box

Technical Field

The utility model relates to the field of packaging technology, concretely relates to reinforced waterproof type paper angle bead that paper packaging box used.

Background

With the development of economy and the improvement of living standard, the packaging and transportation industry of China is rapidly developed. The right angle exists in the inside of paper packing box, has the space between the right angle of these insides and the goods, if the inside buffering packaging material that does not place of space, then the damage that leads to the goods very easily when the packing box jolts. The paper corner protector is a widely used buffering packaging material, and a common paper corner protector is a high-density paperboard formed by pressing multi-layer cardboard paper, but the paper corner protector has poor waterproof and moistureproof capabilities, so that the service life of the paper corner protector is influenced, and the bearing strength of the paper corner protector is also influenced in a humid environment. Therefore, there is an urgent need for a reinforced waterproof paper corner protector for a paper packaging box that can solve the problems of the prior art.

SUMMERY OF THE UTILITY MODEL

The utility model aims at prior art not enough, provide a reinforcement waterproof type paper angle bead that paper packaging box used, this paper angle bead's dampproofing and waterproofing ability is strong, and can improve the intensity of paper angle bead, facilitates the use.

The utility model provides a following technical scheme:

the utility model provides a reinforced waterproof type paper angle bead that paper packaging box used, includes first base plate and second base plate, first base plate with the cross-section of second base plate all is the L type, first base plate with the second base plate surface coats and is stamped waterproof film layer, first base plate with link to each other through the plastics banding around the second base plate, first base plate with form the cavity between the second base plate, be equipped with a plurality of evenly distributed's recess on the first base plate, the concave position of recess is close to the cavity, still be equipped with two gas bags in the cavity, two the gas bag sets up perpendicularly mutually.

Preferably, the cross-sectional shape of the groove is arc-shaped.

Preferably, the cross-section of plastics banding is "コ" type, the plastics banding comprises last banding, lower banding and joint limit, go up the banding with lower banding passes through the joint limit links to each other.

Preferably, the connecting edge is provided with a plurality of strip-shaped grooves, and the strip-shaped grooves are communicated with the cavity.

The utility model has the advantages that:

the first substrate of the paper corner protector is provided with a plurality of grooves, the cavity of the paper corner protector is internally provided with the inflatable bag, and the peripheries of the first substrate and the second substrate are connected through the plastic edge sealing, which is helpful for improving the strength of the paper corner protector and is convenient to use; the utility model is provided with the waterproof film layer on the outer surface of the first base plate and the second base plate, which is helpful to improve the waterproof and moistureproof capability of the paper corner protector by combining the arrangement of the plastic edge sealing; the utility model discloses still be equipped with the bar groove at the plastics banding, the bar groove communicates with each other with the cavity, can play the effect of ventilating when this paper angle bead contacts with the goods.
