Abstract

PURPOSE:To improve space efficiency during storage and transportation effi ciency by putting a plurality of piled flexible porous boards into a non- permeable bag and evacuating the bag to be pressed. CONSTITUTION:A plurality of flexible porous boards 1 molded into a predetermined shape such as felt or flexible polyurethane foam sheet are piled and put into a nonpermeable bag 2. The bag 2 containing the boards is mounted on a lower plate 5 of a press machine 3 comprising an upper plate 4 and the lower plate 5, and a vacuum path 6 is connected to an opening 2A of the bag 2. Then, a pressure inside the bag 2 is reduced, while a pile 1A of the flexible porous boards is pressed in a direction of its thickness via the bag 2 between the upper plate 4 and the lower plate 5. Thus, reduction in pressure eliminates air contained inside the flexible porous boards 1, and also thickness of the boards 1 is compressed by pressing pressure. Thus after the pressure inside the bag 2 is reduced and thickness of the boards is compressed by pressing, the vacuum path 6 is disconnected, and the opening 2A of the bag 2 is heat- sealed to be tightly sealed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package and method for packaging a soft perforated plate such as felt and soft polyurethane foam sheet.

[0002]

2. Description of the Related Art Soft perforated plates such as felt and soft polyurethane foam sheet are used as interior materials and building materials for automobiles, for example. Put, store or user
Had been transported to.

[0003]

However, although such a soft perforated plate is lightweight, it has a large volume and is poor in space efficiency and transportation efficiency during storage.

[0004]

Means for Solving the Problems As a means for solving the above-mentioned conventional problems, the present invention provides a non-airtight closed bag (2) whose inside is in a depressurized state, and compresses the thickness in the closed bag (2). A package consisting of a stack of soft perforated plates (1A) that is stored together is provided, and a plurality of soft perforated plates (1) are further stacked and placed in an air-impermeable bag (2). ) Open the vacuum path (2A)
Contact the (6) to reduce the pressure inside the bag (2) while the soft perforated plate
(1) is pressed in the thickness direction to compress the thickness of the soft perforated plate (1), and then a method for packaging the soft perforated plate in which the opening (2A) of the bag (2) is sealed. .

[0005]

In the present invention, since the thickness of the soft porous plate (1) is compressed, the volume can be reduced and the packaging can be made compact. In order to perform such packaging, the stack (1A) of the soft perforated plate (1) is housed in a non-breathable bag (2) and evacuated, but a large compression rate can be obtained only by evacuating. Since it is not present, the soft porous plate (1) is pressed in the thickness direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to one embodiment shown in FIGS. 1 to 3. (1) is a soft porous plate molded in a predetermined shape, for example, felt, soft polyurethane foam sheet, rubber sponge, etc. The plurality of soft perforated plates (1) are stacked, and the stacked product (1A) is stored in the air-impermeable bag (2).

The bag (2) is, for example, a polyethylene film,
It is made of a non-breathable material such as a polypropylene film, a polyvinyl chloride film, or a polyvinylidene chloride film.

A bag containing the above-mentioned soft porous plate stack (1A)
(2) is placed on the lower plate (5) of the press machine (3) consisting of the upper plate (4) and the lower plate (5), and the vacuum path is provided in the opening (2A) of the bag (2). (6) will be contacted.

The inside of the bag (2) is decompressed via a vacuum path (6), and the stack of soft porous plates (1A) is accompanied by the upper plate (4) and the lower plate (4) of the press machine (3). Press in the thickness direction with the bag (2) between it and 5). In this way, the air contained in the soft porous plate (1) is eliminated by the pressure reduction, and the thickness of the soft porous plate (1) is compressed by the pressing pressure.
Desired compression ratio ((1-thickness after compression / thickness before compression)
X100) should be such that the thickness can be restored when the soft perforated plate (1) is taken out from the bag (2). For example, the soft perforated plate (1) is made of polyester fiber, polyamide fiber, acrylic fiber, In the case of a felt in which fibers such as acetate fibers are mixed with low melting point fibers having a softening point of 150 ° C. or less such as polyethylene fibers, polypropylene fibers and low melting point polyester fibers as a binder, 70% or less, more preferably 65 % Or less. The compression ratio is 70%
If it exceeds, the thickness of the above-mentioned felt is not easily restored.

After depressurizing and pressing the inside of the bag (2) as described above to reduce the thickness of the soft porous plate (1), the vacuum path (6) is removed as shown in FIG. ) Opening (2A)
Is sealed by a heat seal machine (7). Instead of the heat seal described above, the opening (2A) may be sealed with a fastener or the like.

In this way, a package (8) obtained by compressing and packaging the soft porous plate stack (1A) as shown in FIG. 3 in the bag (2) is obtained.

[0012]

Therefore, in the present invention, the transportation efficiency of the soft perforated plate is greatly improved.
