Description

box

technical field

The invention relates to a packaging box, in particular to a foam packaging box suitable for accommodating and protecting fragile objects and having a hard cutting surface.

Background technique

Generally speaking, when transporting or handling brittle objects (semi-finished display panel modules or glass substrates, etc.), the brittle objects are usually placed in a packaging box made of soft materials, and the outside of the packaging box is covered with an adhesive film or other cladding materials. Usually, the packaging box is made of foam material, so that the packaging box can absorb the force during transportation or handling to prevent the brittle items from breaking.

When operators want to take out brittle objects, they usually use knives or sharp objects to directly cut the adhesive film or other covering materials wrapped on the outside of the packing box. In this way, in the process of removing the covering material, the surface of the packaging box made of foam material is easily scratched or cut, resulting in loss of the packaging box, which is not conducive to repeated use.

Contents of the invention

An embodiment of the present invention provides a packaging box, which includes a foam box body, a first fitting part, and a first fixing part. The foam box body includes a box wall and a box bottom. The box wall is connected to the edge of the box bottom, and an accommodating space is formed between the box wall and the box bottom. The box wall has an upper surface, a lower surface opposite to the upper surface, and at least one outer surface connected between the upper surface and the lower surface. The first fitting is located in the box wall of the foam box. The first fitting part extends from the upper surface to the lower surface, the first fitting part has a top face fitted with the upper face, a bottom face fitted with the lower face, connected between the top face and the bottom face and connected with at least one outer surface One of the fitted cutting surfaces, the internal connection surface connected between the top surface and the bottom surface and opposite to the cutting surface, and the top surface, the cutting surface, and the bottom surface and the internal connection surface and between the foam material box Multiple side surfaces that are in contact with the tank walls of the body. Each cutting surface has a channel extending from one side of the upper surface to one side of the lower surface, and the channel communicates with the top surface and the bottom surface. Wherein the first fitting part has a first hardness, the foam box body has a second hardness, and the first hardness is greater than or equal to the second hardness. The first fixing part protrudes on one of the corresponding multiple side surfaces in a direction away from the first fitting part.

To sum up, the packaging box according to one embodiment of the present invention is suitable for accommodating and protecting an object. The packing box has fittings (first fitting and/or second fitting) whose hardness is greater than that of the foam box body, which can provide entry points and/or guide grooves for cutting tools such as knives or sharp objects (groove) to prevent the cutting tool from causing cuts beyond the safety specifications on the foam box, so the operator can directly apply force and/or slide on the fittings of the cutter to quickly disassemble and remove Coating materials such as film and/or belts are used to cover the outside of the packaging box, and the packaging box can be recycled and reused after the objects are taken out, so as to protect the environment and reduce packaging costs.

In addition, the fitting is assembled with the foamed material box in a fitted way, so when the foamed material box or the fitting is worn out (with damage beyond the safety specification), the worn one can be directly replaced to reuse the unworn one .

Moreover, the packing box according to another embodiment of the present invention has a blocking block and an elastic pad, which can be integrally formed with the fitting part depending on the design. Therefore, the stability of the combination between the fitting part and the foamed box body can be increased.

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

The packaging box 400 includes two opposite side blocking blocks 140 located in the accommodation space, and the connection line between the two blocking blocks 140 is used to divide the accommodation space H1 into different spaces, for example, the first space H11 and the first space H11. A second space H12 smaller than the first space H11. When an object (such as a panel with a glass substrate and a circuit substrate) is placed in the accommodating space H1, the glass substrate can be placed in the first space H11 and the circuit substrate can be placed in the second space H12.

To sum up, the packaging box according to one embodiment of the present invention is suitable for accommodating and protecting an object. The packing box has fittings (first fitting and/or second fitting) whose hardness is greater than that of the foam box body, which can provide entry points and/or guide grooves for cutting tools such as knives or sharp objects (groove) to prevent the cutting tool from causing cuts beyond the safety specifications on the foam box, so the operator can directly apply force and/or slide on the fittings of the cutter to quickly disassemble and remove Coating materials such as film and/or belts are used to cover the outside of the packaging box, and the packaging box can be recycled and reused after the objects are taken out, so as to protect the environment and reduce packaging costs.

In addition, the fitting is assembled with the foamed material box in a fitted way, so when the foamed material box or the fitting is worn out (with damage beyond the safety specification), the worn one can be directly replaced to reuse the unworn one .

Moreover, the packing box according to another embodiment of the present invention has a blocking block and an elastic pad, which can be integrally formed with the fitting part depending on the design. Therefore, the stability of the combination between the fitting part and the foamed box body can be increased.

Certainly, the present invention also can have other multiple embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding Changes and deformations should belong to the scope of protection of the appended claims of the present invention.
