Description

Composite combination box

technical field

The invention relates to a composite combined box, in particular to a composite combined box used for transporting fragile plates (such as glass substrates), and a layer of refractory or antistatic material is added on the periphery.

current technology

Referring to FIG. 1 , it is a schematic diagram of a conventional shipping box for fragile plates (such as glass substrates). The shipping box 1 includes a box portion 11 and a cover 12 . The box part 11 is a hollow structure with a bottom, and a plurality of box grooves 111 are provided on the inner sides of the opposite side walls to accommodate a plurality of fragile plates (such as glass substrates) (not shown in the figure), so that the The fragile boards can be parallel and juxtaposed without touching each other. The cover 12 covers the box portion 11 to protect the fragile board inside the box portion 11 . The box part 11 and the cover body 12 are made of the same material, which is polyolefin foam material, and its expansion ratio is usually 3 to 30 times, so it not only has a lighter overall weight, but also can provide cushioning when vibration occurs.

The disadvantage of this conventional shipping box is that the foamed material is flammable and there is a risk of melting or burning in a high temperature environment. In addition, the foam material does not have a good antistatic effect. When the transport box 1 accommodates a glass substrate, the glass substrate is easily damaged by external static electricity, thereby damaging its reliability. In addition, the box portion 11 is integrally formed by foaming the foam material. If the box body groove 111 collides with the fragile plate and is damaged, the entire box body cannot continue to be used, resulting in an increase in cost. And the shortcoming of this kind integral molding is that the expansion ratio of this foaming material must not exceed 30 times (because its side wall can be insufficient in strength when exceeding 30 times), so the protective function and the effect of its casing will be severely limited.

Therefore, it is necessary to provide an innovative and progressive shipping box for fragile boards to solve the above problems.

Contents of the invention

The main purpose of the present invention is to provide a composite combined box, which includes a box part and a cover.

The box part includes a box inner layer and a box outer layer. The inner layer of the box is a hollow structure, the inner side wall of the inner layer of the box has a plurality of box grooves to accommodate the fragile board, and at least one outer side wall of the inner layer of the box has at least one box track . The outer layer of the box is a hollow structure for accommodating the inner layer of the box, and the inner side of the side wall of the outer layer of the box has a box groove corresponding to the track of the box. The material of the outer layer of the box is different from the material of the inner layer of the box. The material of the inner layer of the box is foam material, and the material of the outer layer of the box is fireproof material or antistatic material.

The cover system covers the box part.

In other words, the present invention relates to a composite combined box, which includes:

A box section which has:

A box inner layer, which has two opposite side walls, the inner side of at least one opposite side wall of the box inner layer has a plurality of box body grooves to accommodate at least one fragile plate, and the outer side of at least one side wall of the box inner layer having at least one first connection device; and

A box outer layer, which is a hollow structure for accommodating the box inner layer, the inner side of the side wall of the box outer layer has a second connecting device corresponding to the first connecting device, and the box body the material of the outer layer is different from the material of the inner layer of the box; and

a cover covering the box,

Wherein the first connecting device is a box track, and the second connecting device is a box groove.

Therefore, the outer layer of the box can provide fireproof and antistatic effects, and when the groove of the box is damaged, only the inner layer of the box needs to be replaced, and the outer layer of the box can be reused, which can greatly reduce cost. In addition, this at least double-layer structure, because the required strength is assisted by the outer layer of the box, the expansion ratio of the foam material in the inner layer of the box is not limited to 30 times, which can greatly increase the ease of storage. Shockproof effect of broken board.
