Abstract

Disclosed is a buffer medium for shock absorption. On one surface and the opposite surface of the buffer medium, protrusions having different installation heights are provided, and a thin film which is elastic and thin and made of a vinyl paper or a silicone film is attached to one of the surfaces of the buffer medium. Accordingly, an angle of folding toward the inside of the buffer medium is minimized, while a thickness of the elastic wall toward the outside of the buffer medium is maximized, so it is possible to provide a buffering effect while improving flexibility in a diagonal direction as well as in length and width directions. The buffer medium can increase unfolding resilience if the buffer medium is used as a packaging material. If the buffer medium is used as a packaging container, various types of goods can be easily and firmly packed while the shape of the goods can be prevented from being crushed, product value of the packaged goods can be improved by a neatly folded appearance, and there is no need to worry about environmental contamination due to excellent recyclability. The buffer medium, while adding elasticity together with water resistance, can prevent moisture coming out of the contents from moistening the packaging container when goods containing the moisture, such as agricultural or marine products or frozen food, are packaged.

Description

Shock absorbing buffer core {SHOCKING ABSORBER FOR PACKING}

The present invention relates to a shock absorbing buffer core, more specifically, a protrusion having a height of installation that protrudes differently so as to minimize the folding angle with respect to the inner direction of the core, and maximize the thickness of the elastic wall in the outer direction of the core. It relates to a buffer core installed intersecting in the vertical direction.

In other words, the present invention provides a cushioning effect and improves the flexibility in the longitudinal direction and the width direction as well as the diagonal direction, and can increase the unfolding restoring force when using this as a packaging material, and when the packaging container is used, Various types of items can be easily and firmly packed while being prevented, and the neatly folded appearance improves the value of the packaged goods. It relates to a buffer core for absorption.

In general, glass products that are relatively weak in durability, such as cosmetics, electronic / electrical products that are vulnerable to impact resistance, such as TVs, or other items requiring considerable care in handling, are usually packaged together with a shock absorber in a rigid box.

The shock absorber is used to protect the packaged goods by absorbing the impact on the box from the outside.

In the prior art, a styrofoam molded in the form of an article or a ground configured to be folded or cut out in a certain form so that the article can be fixed, or an air cap is generally used as the shock absorber.

In addition, when the product to be packaged has a heavy weight, such as a refrigerator, wooden pallets are widely used because the shock absorbing performance against external impact and durability capable of supporting the weight with sufficient force are required.

In the case of the shock absorber made of styrofoam has the advantage of easy molding and mass production, styrofoam has the disadvantage of easily broken and causing static electricity. Therefore, styrofoam is not only used to package high-precision products due to the generation of static electricity, as well as polluting the surroundings due to easy breakage.

In other words, styrofoam will be limited to only a limited field.

On the other hand, in the case of a convex air cap filled with air inside, it is widely used to prevent breakage or breakage while packing home appliances or bowls when moving or packing items in case of courier service. The cap is also not waterproof because it fills the empty space by filling the air-convex convex air cap with several layers of air in the case of moving or home packaging. There was a problem popping even if you apply force.

In particular, as the awareness of environmental preservation is gradually increasing in recent years, much attention has been focused on the disposal of used packaging materials. Packaging materials using styrofoam, airbags and plastics are not recycled and their separation work is cumbersome and discarded. As it causes pollution, the use is gradually being suppressed for the protection of resources and the environment.

On the other hand, the ground formed by folding the paper into a certain form and assembled, has the advantage of easy separation and recycling, but not only mass production is difficult, but also durable, and contaminated the packaged product by generating a large amount of stake during assembly It can cause side effects such as lethal effects.

Packaging cases that are molded using pulp mold have been recently developed and used, but such packaging cases increase manufacturing costs with difficulty in manufacturing since a separate mold is required even when manufacturing a small amount.

In recent years, shock absorbers using bone wicks have been widely used. The corrugated paper is made of a multi-layered paper having a predetermined strength. The corrugated paper is formed by dot-gluing each liner on the upper and lower bone tops of the continuously curved corrugated paper to form an air chamber between the liners forming both outer surfaces. In addition to having strength, it has a function of absorbing shock absorbers that absorb shocks from the outside.

However, when manufacturing a packaging container or shock-absorbing inner packaging material using the corrugated core, it has a predetermined strength and shock absorbing power, but has a shape that can be folded only along the bone of the corrugated core, thereby making the packaged article complicated If it has an outer surface, it is difficult to pack it to be in close contact with the outer surface of the article, and when the corrugated core is forcibly folded according to the shape of the article, the core and the outer liner are crushed while deforming the shape, which lowers the strength and shock absorption. Rather, there is a problem that the product value of the packaged goods is greatly reduced due to the crushed packaging state.

Accordingly, the present applicant has disclosed a 'shock absorbing inner packaging material and a packaging container using the same' of Patent Publication No. 10-0358724 to improve the above problems, the present invention is to improve the pre-registered patent of the present applicant as described above It is.

That is, the pre-registered patent of the applicant of the present invention has the same size as the outward protrusions (or upward protrusions) and inward protrusions (or downward protrusions), as well as the protrusion height thereof, and when used as a packaging material or a packaging container, the burnt toward the outer side of the core core While maximizing the thickness of the wall and minimizing the folding angle in the inner side of the corrugated core, it was difficult to proceed, and also had the disadvantage of inflexibility in the longitudinal direction, the width direction, and the diagonal direction of the corrugated core.
