Problems solved by technology

[0003] Most of the existing packaging containers made of foamed polyethylene are made by slicing, punching, pasting, sewing and other processes, which require more labor, resulting in higher labor costs, and are prone to degumming, cracking, and leakage at the joints. Gas and other phenomena, the heat preservation effect is difficult to guarantee, and it is difficult to make a shape that adapts to the shape of the packaged object, especially a shape with a spherical curvature, and the shock absorption effect is also limited. The large volume makes storage and transportation difficult, and it is easy to cause packaging waste such as material damage and excessive packaging costs

Embodiment 1

[0044] Example 1, through figure 1 to image 3 , a packaging container made of foamed polyethylene, including the side and bottom, made of a whole piece of foamed polyethylene material, used for packaging tools for holding items, such as electronic products, ceramics, chilled food, medicine and vaccines For easily damaged items or other items, the inside and outside of the side and bottom surfaces can be made into shapes including spherical radians, bumps, different hardness, and different densities, and the inside and outside of the sides and bottom surfaces are equipped with or without protective layers. .

[0045] The inside of the packaging container is made of a concave-convex shape (same as marked (1) and (6)) that is adapted to the shape of the packaged object, which can make the shape of the inside of the packaging container and the shape of the packaged object The shape fits closely, so that the inner protective layer (as shown in the mark (5)) can provide more sec...

Embodiment 2

[0046] Example 2, by figure 1 to Figure 4 , a packaging container made of foamed polyethylene, including the side and bottom, made of a whole piece of foamed polyethylene material, used for packaging tools for holding items, such as electronic products, ceramics, chilled food, medicine and vaccines For easily damaged items or other items, the inside and outside of the side and bottom surfaces can be made into shapes including spherical radians, bumps, different hardness, and different densities, and the inside and outside of the sides and bottom surfaces are equipped with or without protective layers. .

[0047] Add an upper cover (mark 9) on the edge of the packaging container to form a sealing band with the edge of the packaging container (mark 2), so that the packaging container can not only absorb shock, buffer and prevent In addition to impact, it also has a good thermal insulation function and can be used as a thermal insulation packaging container.

Embodiment 3

[0048] Example 3, by figure 1 , figure 2 , Figure 5 , a packaging container made of foamed polyethylene, including the side and bottom, made of a whole piece of foamed polyethylene material, used for packaging tools for holding items, such as electronic products, ceramics, chilled food, medicine and vaccines For easily damaged items or other items, the inside and outside of the side and bottom surfaces can be made into shapes including spherical radians, bumps, different hardness, and different densities, and the inside and outside of the sides and bottom surfaces are equipped with or without protective layers. .

[0049] Use a certain force (same as the direction marked 10) to press the side to the bottom to make it fold, so that the space inside the packaging container is reduced and becomes a state of smaller volume (same as marked 11), reducing inventory and transportation costs.

Abstract

A packaging container made of foamed polyethylene. The main body is made of a whole piece of foamed polyethylene material through physical deformation. It is composed of a bottom surface and a side surface. Adaptable specific quilts are set inside and outside the sides and bottom surfaces. The shape of the packaging, or the one that can buffer, guide, and disperse external impact forces, may include concave and convex shapes with spherical arcs; protective layers may or may not be provided on the inside and outside of the sides and bottom surfaces; the configuration may be formed with the edge of the packaging container The upper cover of the sealing tape enables the packaging container to be sealed and has a heat preservation function; it reduces the force of external impact on the packaged items, increases the stability of the packaged items during transportation, keeps the temperature constant, and effectively reduces the damage caused by the external environment. Damage to the packaging; it has a certain memory function and can be forcibly folded without affecting the use efficiency, effectively reducing inventory and transportation costs.

Description

technical field [0001] The invention relates to the field of article packaging, in particular to a packaging container made of foamed polyethylene. Background technique [0002] Foamed polyethylene, commonly known as pearl cotton, is a material with low thermal conductivity, cushioning, and strong shock absorption. Packaging containers made of foamed polyethylene refer to packaging tools used to hold items, such as electronic products, ceramics, ice For easily damaged items such as fresh food, medicine and vaccines, or other items, its main function is shock absorption and heat preservation, which is convenient for transportation and carrying. [0003] Most of the existing packaging containers made of foamed polyethylene are made by slicing, punching, pasting, sewing and other processes, which require more labor, resulting in higher labor costs, and are prone to degumming, cracking, and leakage at the joints. Gas and other phenomena, the heat preservation effect is difficul...
