Description

[Detailed Description of the Invention] The present invention relates to a hermetically sealed package in which a packaged object such as various types of futons, cushions, clothing, etc. is reduced in size by vacuum degassing and then sealed with a film.

There is an advantage that the sealed package as described above can be handled with a reduced volume.

However, on the other hand, wrinkles occur around the shrunk packaged object, and these wrinkles are visible through the film, reducing the commercial value.

Furthermore, depending on the type of the packaged item, the periphery may be pressed, and creases may occur around the periphery.

In order to prevent or reduce the occurrence of wrinkles, it is necessary to reduce the degree of vacuum degassing, which results in an insufficient reduction in bulk.

The present invention proposes a sealed package that can solve the above problems, and one embodiment thereof will be described below with reference to the drawings.

FIG. 1 shows a folded mattress 1, which is an example of an article to be packaged, and FIG. 2 shows an unfolded formwork 2.

This formwork 2 is made of cardboard, cardboard, thin resin board, etc.
It consists of an annular plate part 3 forming four side edges of the bottom surface, and a side wall plate part 5 connected to the four side edges of the annular plate part 3 via folds 4 to form four side edges.

As shown in FIGS. 3 and 4, the futon 1 is placed in the formwork 2 with the side wall plate 5 upright, and with these 2.1 inserted into the film 6 and sealed, film 6
The inside is vacuum degassed to form a sealed package 7.

According to this, the formwork 2 is located between the film welded part 6A and the pillow surrounding area 1A.

8 indicates a hand hole. As mentioned above, according to the sealed package of the present invention, the formwork is located on the four side edges of the bottom surface of the packaged object and on the outside of the four side edges, thereby eliminating the wavy wrinkles that occur when the packaged item is sealed and deaerated. It can be hidden and the product value can be improved.

Moreover, even if the bulk is sufficiently reduced by strong vacuum deaeration,
The presence of formwork can minimize the occurrence of creases.

Furthermore, sealed packages can be standardized depending on the height and shape of the formwork, making handling such as transportation and stacking convenient.
