Description

Expandable Pulp Molded Buffer

technical field

The utility model relates to a packing buffer, in particular to an expandable pulp molded buffer, which is suitable for packing liquid crystal screens, CD-ROMs and other electronic products.

Background technique

Packaging buffers are used as fillers when electrical products are packed to prevent damage to products caused by accidental extrusion and collision during stacking or transportation. Pulp molded cushioning materials are easy to recycle and have no pollution to the environment. In recent years, they have been widely used in packaging as a substitute for foaming materials.

The unfolded pulp molded cushioning part refers to the one-piece cushioning part with folded edges, such as the "four-sided unfolded paper support cushioning package" disclosed in Chinese utility model CN2520302, which is composed of a bottom plate and a folded plate on the side. Connected by a folded edge, at least one accommodating cavity is provided in the base plate and the folding plate, and a plurality of reinforcing ribs are provided around the accommodating cavity. When packing, fold the buffer and put it into the packing box, and then insert the packaged objects (such as LCD screen, CD-ROM, etc.) Cushioned by the bottom and sides.

However, during use, it was found that the folded folding board could not maintain a position perpendicular to the bottom board due to the lack of support, so when the packaged goods were placed inward, the folding board would tilt inward, and one side of the folding board needed to be supported On the other side, it is inconvenient to pack the packaged objects into the cavity, and even requires multiple operators to work together at the same time, which is time-consuming and labor-intensive.

Contents of the invention

The purpose of the utility model is to provide an unfolded pulp molded cushioning part, through the improvement of the structure, the packing and use of the cushioning part is more convenient.

In order to achieve the above purpose, the technical solution adopted by the utility model is: an unfolded pulp molded buffer, mainly composed of a base plate and at least one folded plate arranged on the side of the base plate, the base plate and each folded plate They are respectively connected by a folded edge, and the inner side of the bottom plate and the folded plate are provided with a plurality of accommodation positions separated by reinforcing ribs. When the folding plate is in the folded state, it is limited by the position-limiting structure at a position perpendicular to the bottom plate.

In the above technical solution, there are two states of use, the unfolded state and the folded state. When the product is manufactured, it is in the unfolded state, which is easy to be stacked and transported; when in use, it is in the folded state, which is placed outside the product, including the box, for Buffer multiple faces. Wherein, the "inside" refers to the side that constitutes the accommodation space in the folded state. Unlike the folded edge in the prior art, the inside of the folded edge is also provided with a limiting structure, that is, the folded plate and the bottom plate There is a limit structure at the adjacent part of the fold. Through the setting of the limit structure, when the folding plate is turned inward to the vertical position, it is limited by the limit structure and cannot continue to be folded inward. Put it into the packing box and fold it The plate and the bottom plate can maintain a vertical positional relationship, and the storage position of the folding plate is connected with the storage position of the bottom plate to form a part of the storage space together, so that the package can be smoothly placed in the storage space; in actual use, it can be combined with Two cushioning pieces of this scheme are selected as the upper and lower cushioning pieces of the package respectively.

In the above technical solution, there may be 1 to 4 folding plates, which are respectively suitable for cooperative use in different situations. When used for thinner objects such as notebook computers and optical disc drives, generally multiple products are placed in parallel in one packing box. At this time, the preferred technical solution is to include two folding plates, which are respectively arranged on on a pair of opposite sides. Under this scheme, the product is put into multiple accommodating spaces formed between a pair of folding plates and the bottom plate in parallel, and an additional buffer pad can be inserted on the front and rear sides of the product respectively. Folding boards on both sides limit the position, and the front and rear buffer pads do not need to limit the position. Since the structure of this technical solution only needs to be unfolded on two sides, it has lower requirements on production equipment and technology, and is a preferred technical solution.

In the above technical solution, the position-limiting structure is that the upper surface of the reinforcing rib is located on the inner side of the surface where the folding edge is located, and the reinforcing ribs adjacent to each other when the folded plate and the bottom plate are folded are respectively provided with mutually cooperating limit bevel.

Another technical solution of the position-limiting structure is that at least one support rib structure is provided at the folded adjacent place between the bottom plate and each folded plate, wherein a support rib is provided on one plate, corresponding to the position of the support rib. The other plate is provided with a slot for plugging and matching with the support rib, and the side of the support rib near the side of the bottom plate matches the bottom surface of the slot of the bottom plate.

The preferred solution is to combine the above two limiting structures, not only to set the limiting slope, but also to set the supporting ribs at least one fold adjacent to it, so as to provide sufficient lateral cushioning strength for the package , At the same time, it can prevent the front and rear displacement and deformation of the buffer.

Due to the use of the above technical solutions, the utility model has the following advantages compared with the prior art:

1. Since the utility model is provided with a limit structure between the folding plate and the bottom plate, after the buffer is put into the packing box, the vertical relationship between the folding plate and the bottom plate is maintained, which facilitates the placement of the packaged objects;

2. Since the folding plate and the bottom plate are folded and overlapped with a limited slope, on the one hand, it limits the inversion of the folding plate, and on the other hand, it increases the lateral cushioning strength of the buffer, which helps to protect the packaged goods;

3. Due to the plug-in cooperation between the support rib and the slot, while limiting the position of the folding board, it also limits the front and rear displacement and deformation of the folding board, and improves the cushioning effect.
