Abstract

The utility model discloses a packaging structure that can be stacked in multiple layers, comprising "L"-shaped cardboard corner protectors (2) placed on the four peripheral corners of the bottom and top of the box body (1) and placed around the box body (1). The pearl cotton protection strip (3) on the side; the utility model adopts four peripheral corners "L" type hard paper corner guards and the surrounding pearl cotton protection strip frame to form a supporting column structure, which is assembled and matched with the carton and the product to form a whole to ensure When the product is stacked under pressure, it deforms evenly without causing dumping. At the same time, the corner of the paper bears most of the pressure, which greatly reduces the chance of the product being crushed, improves the overall packaging strength of the product, and maximizes the stacking layer of the product. Number, improve product packaging protection capabilities, and reduce packaging costs.

Description

A packaging structure that can be stacked in multiple layers

technical field

The utility model relates to the technical field of refrigerators in household appliances, in particular to a packaging structure that can be stacked in multiple layers.

Background technique

At present, home appliance companies and sales stores have limited storage warehouses, and it is necessary to increase the number of stacking layers of products to increase the utilization rate of warehouses. At present, for refrigerator home appliances, in the Chinese market, the stackable layers of 150-250L refrigerator products are up to three layers, and products below 150L can be stacked everywhere. When the warehouse wants to improve the warehouse utilization rate and continue to stack , There will be situations where stacked products are dumped and the bottom product is crushed.

Therefore, it is necessary to increase the packaging strength of the product, and increase the number of stacking layers on the premise of increasing the product packaging cost as little as possible.

Utility model content

The technical problem to be solved by the utility model is to provide a packaging structure in which four peripheral corners are made of hard paper corners, and the sides are made of hard paper protection strips as support columns to improve the overall packaging strength of the product and maximize the number of product stacking layers.

The technical solution of the utility model is: a packaging structure that can be stacked in multiple layers, including "L" type hard paper corners placed at the bottom and top four peripheral corners of the box and pearl cotton protection placed on the sides of the box. strip.

The top of the box body is also equipped with a top cover, and the four corners of the top cover are inserted into the four cardboard corner guards provided on the top of the box body (1).

The bottom of the box body is also equipped with a bottom pad, and the four corners of the bottom pad are inserted into the four cardboard corner guards provided at the bottom of the box body.

The structural principle of the utility model is briefly described as follows:

The product is stacked too high and easy to tilt. First, because the gravity distribution of the product itself is uneven, and the bottom cushion of the product package is generally made of EPS foam material, and the density of the foam cushion of household appliances is generally 15-30kg/ ^m3 . There will be a certain amount of deformation after the load pressure of the product's own weight. Generally, the center of gravity of the refrigerator product is at the rear, because the compressor is heavier, so after the refrigerator product is packaged and undergoes transportation vibration, the rear of the outer packaging of the product is lower than the front. When the same product is stacked on the product and the direction is consistent, the pressure at the rear will be greater, and the deformation of the first layer of products will be greater than that at the beginning. Therefore, when the center of gravity of the stacked product is exceeded, it will There will be a dumping phenomenon.

There are two ways to increase the number of stacking layers and not to collapse the box. One is misplaced stacking, that is, the direction of the second layer is opposite to that of the first layer, and the deformation of the upper layer is used to offset the deformation of the lower layer; The deformation of small product packaging, or make the deformation of each point consistent, to ensure the balance of the top. The utility model adopts the second method.

The beneficial effect of the utility model relative to the prior art is:

The utility model adopts four peripheral corners "L" type hard paper corner guards and pearl cotton protective strips around to form a support column structure, which is assembled with cartons and products to form a whole to ensure that the products are evenly deformed when they are stacked and pressed It will not cause dumping, and at the same time, the corner of the paper bears most of the pressure, which greatly reduces the chance of the product being crushed, improves the overall packaging strength of the product, maximizes the number of stacking layers of the product, improves the protection ability of the product packaging, and reduces packaging costs.

Detailed ways

Referring to Figure 1, Figure 2, Figure 3, Figure 4, Figure 5, Figure 6 and Figure 7, a packaging structure that can be stacked in multiple layers, including "L"-shaped Cardboard corner protector 2 and the pearl cotton protection strip 3 placed on the sides of the casing 1, the top of the casing 1 is also equipped with a top cover 4, the bottom of the casing 1 is also equipped with a bottom pad 5, the top cover 4 and The bottom pad 5 leaves space for inserting the corner protector 2 on the four corners, and inserts the cardboard corner protector 2 into the four corners of the top cover 4 and the bottom pad 5 to form a frame structure around the frame. The schematic diagram after assembly Figure 1.

The hard paper corner protector 2 adopts hard kraft paper with a thickness of 5mm and a size of 50mm×50mm, and the pearl cotton protective strip 3 can be made of EVA or EPE material.

When using the utility model, the product is assembled with cardboard corner protector 2, pearl cotton protection strip 3, top cover 4 and bottom pad 5 and then put on a carton. Compact, the schematic diagram of the packaged box is shown in Figure 8.

In this way, after the products are stacked in multiple layers, the paper corner protectors form an integral frame to withstand most of the pressure, ensuring that the products are evenly deformed and will not cause dumping when the products are stacked under pressure, thereby greatly reducing the chance of the product being crushed probability. The utility model can improve the overall packaging strength of the product, maximize the number of stacking layers of the product, improve the protection ability of the product packaging, and reduce the packaging cost.
