Description

Integrated packing box

Technical Field

The utility model relates to a case.

Background

The box is a rectangular tool with a cover, which is convenient for holding articles, and can be made of leather, wood, iron sheet, plastic and the like.

The aluminum alloy box mainly takes aluminum alloy materials as a framework, takes ABS, a density board (medium density board), a clamping board (multi-layer board) and the like as a panel, and takes tee joints, port bars, handles, locks and the like as accessories to form the box body. The foam material such as sponge or foam is placed in the interior of the cup, and the cup can be widely applied to placing beauty and hairdressing, tool combination, jewelry watches, instruments and meters and the like. However, some aluminum alloy boxes are made of more materials, more parts and higher cost.

The foam box is a box-type packaging container made of foamed plastic, and the foamed plastic is plastic with a plurality of tiny pores inside. The characteristics are as follows: the expandable polystyrene foam plastic is a novel shockproof packaging material and a novel heat-insulating material. It has the advantages of light specific gravity, impact resistance, easy forming, low cost, etc. The disadvantage of some foam boxes is their low strength and their susceptibility to embrittlement.

Disclosure of Invention

The utility model aims to: the integrated molding packing box has the advantages of simple manufacturing equipment, lower manufacturing cost, larger strength and rigidity, and better rebound resilience and flexibility.

The technical scheme is as follows:

the integrated formed inner and outer packing cases are made of a foamed polymer material (foamed polyethylene, foamed polypropylene or foamed polybutene, preferably foamed polypropylene, and the foamed polypropylene has good mechanical strength, is not easy to crack, has flexibility and rebound resilience and rigidity for shape retention, is a thermoplastic material, has low light hydrocarbon combustion toxicity) and is made into an integral main body, the main body comprises an upper cover and a lower cover, the thickness of the material of the upper cover and the lower cover is thicker (the rigidity is kept better), and one side (opposite sides of the separated side and the two sides are parallel) of the upper cover and the lower cover, which are connected together by virtue of a thin polymer material connecting section (the upper cover and the lower cover are convenient to bend, open or fold without a hinge). That is, the thickness of the upper cover and the lower cover is larger than that of the connecting section, and the opposite sides of the upper cover and the lower cover at the separated sides are connected by the connecting section.

A strip-shaped (or waist-shaped) hand-held hole is respectively arranged near the edge between the two groups of metal buckles on one side of the upper cover and the lower cover which can be separated, and a handle is naturally formed outside the hand-held hole, or a hand-held handle is only connected to the upper surface of the upper cover, so that the hand-held packaging box is convenient to carry.

The two sides of the hand hole are respectively provided with a group of female buckles and male buckles which can be matched and connected with the metal buckles, so that the lower cover and the lower cover are tightly buckled together after being covered, and the built-in articles cannot be exposed or fall off.

The lower cover is internally provided with one or more concave grooves (the articles are laid down or vertically placed in the grooves) which are arranged side by side or side by side (or arranged) and are convenient for placing the articles, and the grooves are in a shape which is symmetrical left and right along a central line or an asymmetrical shape (symmetrical articles or special-shaped articles can be placed).

Preferably, the groove is provided with an upper cavity (one side close to the hand hole), a middle cavity and a lower cavity which are communicated with each other; the middle cavity is strip-shaped, and the cross section (the cross section perpendicular to the central line) of the middle cavity is smaller than that of the upper cavity and the lower cavity; when placing the article with the matched size, the middle of the article is blocked by the middle cavity and cannot move up and down. The height of the upper cavity is smaller than that of the lower cavity, the lower cavity is convenient for placing the bottle body of the bottle, the upper cavity is convenient for accommodating the bottle cap, and the middle cavity is convenient for accommodating the bottle neck.

Preferably, the width of the upper cavity or the lower cavity is larger than the depth of the upper cavity or the lower cavity, and the upper cavity or the lower cavity can be used for placing objects with rectangular cross sections, so that the objects can not rotate after being placed, and the objects are stable.

Preferably, an elastic band is arranged above the lower cavity or the middle cavity, and two ends of the elastic band are respectively fixed at the left side and the right side of the inside of the lower cover (or the upper cover), so that the built-in articles are conveniently bound, and the articles are not easy to fall off.

Preferably, the upper cover is internally provided with grooves which are symmetrically arranged with the lower cover (along the connecting section) and are convenient for placing articles.

When the grooves are a plurality of grooves arranged side by side, circular small grooves are preferably arranged between the middle cavities of the adjacent grooves, so that a bottle opener for opening the bottle cap can be conveniently placed or the bottle cap (a part plugged into the bottle neck) can be inserted.

Preferably, the two opposite sides of the upper cover and the lower cover are not parallel to the upper surface of the upper cover, and have an inclined angle of 30-60 degrees.

The beneficial effects are that:

the integrated molding packing box provided by the utility model is formed by foaming the whole body in a mould without forming an outer box and foam arranged in the outer box, and has the advantages of simple manufacturing equipment and lower manufacturing cost. The strength and the rigidity are both high, but also has better rebound resilience and flexibility. The scrap can be wholly returned to the furnace for melting and remanufacturing without being split during scrapping and recycling. And the corrosion resistance and the washing resistance of the material are good.
