Description

[Detailed Description of the Invention] The present invention relates to a cushioning material that also serves as a partition frame for use in packaging containers.

The first object of the present invention is to provide a cushioning material for packaging containers that is highly resistant to pressure and is foldable and foldable.

The second object of the present invention is to provide a partition frame for packaging containers that is excellent in workability.

The details of the present invention will be explained with reference to the drawings.

A main body 1 for a cushioning material having a U-shaped cross section is provided by opening both sides and forming upright pieces 2 on the front and back sides.

Then, a first fold 3 is formed at the base of the upright piece 2 in a direction perpendicular to the side surface of the main body 1 for cushioning material, and a second fold 3 is formed in the center of the bottom surface of the main body 1 for cushioning material in parallel with the first fold 3. A fold line 4 is formed, and a large number of honeycomb structure papers 5 which are expandable and contractible in a direction perpendicular to the first fold line 2 and the second fold line 4 are arranged in a row on the inside of the above-mentioned coexistence upright piece 2, and the coexistence upright piece 2 Honeycomb structured paper 5 adjacent to the inner surface of
It is made by adhering only A to its inner surface.

What is the honeycomb structure paper 5 referred to here?
As shown in the figure, many pieces of paper such as kraft paper are lined up vertically and some of the pieces of paper are partially glued together. It becomes a number of plate-like objects, and when it is stretched, it takes on the shape of a honeycomb when viewed from above.

The present invention is constructed as described above, but for further convenience of use, only the first fold 3 side is connected to the upright piece 2 on both sides or one side of the second fold 4 provided at the center of the bottom surface. A notch 6 representing a rectangular or other suitable shape as shown in the figure from the first fold 3 to the second fold 4.
The support piece 7 is provided by.

Note that the size of one unit of the honeycomb-shaped space formed by the honeycomb structured paper 5 is relatively small in the illustrated case;
In this case, the present invention can be used as a partition frame by storing, for example, a small-diameter ampoule of a chemical solution in the above-mentioned space.

Therefore, if the size of the space is formed to correspond to the size of the object to be accommodated, it can be used as a partition frame regardless of the size of the object to be accommodated.

Furthermore, when used as a cushioning material, it is also possible to adjust the resistance pressure by forming the size of the honeycomb-shaped space to be large or small depending on the purpose.

The present invention is constructed as described above, so to explain how to use it, as shown in Fig. 3, when the present invention is pressed in the direction of the arrow S and becomes a plate shape, it is stretched in the direction of the arrow O and folded into a second shape. The cross section changes from being folded in half to a U-shaped cross section based on eye 4.

In this state, it is placed in the bottom of the packaging container, and the article to be packaged is placed thereon while holding the honeycomb structure paper 5 so as not to shrink it.

In this case, the honeycomb structured paper 5 side may be placed toward the bottom of the container, or the main body 1 may be placed on the bottom.

In addition, when using the support piece 7, as shown in FIG. The article to be placed and packaged is fixed to the main body 1 with, for example, tape, and the support piece 7 is bent back to the original position of the notch 6, and the main article is placed in the container together with the article to be packaged.

In addition, when using this proposal as a partition frame for packaging containers,
All that is required is to stretch the honeycomb structured paper 5 in advance to form spaces in the cardboard box as shown in FIG. 1, and then store objects in each of these spaces.

In the present invention, a stretchable honeycomb structure paper 5 is provided and folds 4 are formed in the main body 1, so that it can be folded and folded freely and is not bulky.

Moreover, since the honeycomb structure paper 5 covers most of the paper, it has high pressure resistance and is composed of air layers, so it is light in weight and convenient for transportation.

In addition, the present invention can be used as is as a partition frame for packaging containers, but when in use, the compressed honeycomb structure paper is simply stretched inside the cardboard box, and the items to be stored can be stored in a large number of honeycomb-shaped spaces. .

Conventional partition frames usually have a large number of strip-shaped frame pieces with notches in the width direction at regular intervals, and when used, these frame pieces are inserted into the notches and folded to create an invisible lattice-shaped partition. Because the frame was formed to accommodate the stored items, it was time-consuming to prepare the partition frame, and there was a problem in improving work efficiency.However, as described above, the present proposal is simply stretching the honeycomb structure paper. Workability is excellent because objects can be stored immediately.

Moreover, since bendable support pieces are provided on the first fold side of the bottom surface of the main body by cutting in each case, when in use, these support pieces can be bent outward by 90 degrees and touch the sides of the support base. By bringing them into contact with each other, the stretchable honeycomb structured paper is maintained in its stretched state without being restored to its plate shape, so packaging operations can be carried out without worrying about it becoming plate-shaped.

In addition, if the supporting piece is provided only on one side, the supporting piece can be brought into contact with the side of the support stand, and the honeycomb structure paper can be stretched by holding the upright piece on the opposite side of the supporting piece. This state can be used for packaging work. can be done.
