[0009]

In the present invention, the foamed product is compressed by being pressed by the pressing member while being sandwiched by the film-like material from above and below. After the foamed product is compressed to a desired state, the film-like material is fixed and hermetically sealed, so that a packaged compressed foamed product is easily obtained. At this time, by performing the pressing and compressing of the foam product in the frame, the foam product can be prevented from being deformed to the side at the time of pressing and compressing, and the tension is applied to the film used as the packaging material at the time of pressing and compressing. By performing the pressing and compression, the generation of wrinkles of the packaging material can be prevented, and the smooth pressing and compression can be performed. In addition, the presence of the foaming product restoration aid in the foamed product allows instant restoration of the foamed product upon opening.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the drawings are schematic diagrams for explaining the present invention, and for convenience of explanation, parts that are originally close parts are illustrated with a gap. FIG. 1 shows a compression packaging method for a foam product of the present invention. First, FIG.
As shown in (1), a film 4 made of polyvinyl chloride as a part of the packaging material is placed on the pedestal 1, and a foam product P to be compressed and packaged is placed thereon. Another PVC film 5 is covered so as to cover the foam product P, and the foam product P is pressed from above by the flat pressing member 2, for example. Pressing member 2
The foamed product P is compressed by the pressure of, and the compression usually causes the foamed product to be deformed in the lateral direction. At this time, a cylindrical frame 3 slightly larger than the outer shape of the foam product in the compression direction is used, and the foam product P
The upper wrapping film 5 is stored and placed, and preferably, the upper wrapping film 5 is pressed and compressed while applying an outward tension. Thus, the foam product P can be smoothly compressed, and the foam product can be prevented from being deformed in the lateral direction.

The frame 3 may be of any cylindrical shape such as a cylinder or a square tube, and the inner shape and size of the cross section thereof are at least housed in the frame without deformation of the foam product. The shape and size are preferably. The inner shape of the frame 3 is similar to the maximum outer shape of the foam product in plan view, and is preferably slightly larger than the maximum planar shape of the foam product from the viewpoint of preventing deformation of the foam product.
This is because if there is an appropriate gap between the surrounding frame and the foam product, even if the foam product is deformed during compression, the surrounding frame prevents further deformation of the foam product, and This is because quality deterioration due to excessive rubbing with the surface of the frame around the foam product is sometimes reduced. At this time, when the film 5 exists between the foamed product P and the frame 3 and compression is performed in a state where a moderate outward tension is applied thereto, these effects become more remarkable. . However, the internal cross-sectional shape of the frame 3 does not need to be as described above as long as the quality does not deteriorate during the pressing and compression of the foam product. That is, the foamed product may be housed in the frame in a deformed and compressed state, and may be pressed and compressed by the pressing member, or may not have the similar shape described above.

On the other hand, the shape of the pressing member 2 is the same or substantially the same as the inside shape of the frame 3 and the size is preferably slightly smaller than the inside of the frame. The shape is not limited to these. The entire foam product can be pressed and compressed without damaging the upper packaging film 5 or the foam product P placed on the foam product P and without causing excessive deformation of the foam product P in the lateral direction. The pressing member may be of any shape and size.

Incidentally, the foamed product P to be pressed and compressed may be deformed before being pressed and compressed, such as being folded, in some cases. The inside shape and size of the cross section may be appropriately selected considering the folded shape as the shape of the foam product. That is, the shape and size of the frame 3 and the pressing member 2 are within a range in which a desired compressed foam product can be formed in a deformed state by being pressed and compressed.
May be determined.

The frame 3 only needs to be disposed around the foam product P at least when the foam product is pressed and compressed, and may be fixed or movable.
Further, the frame 3 may be made up of two or more members, and may be openable. For example, when the frame 3 is fixed, it is preferable that the frame can be opened so that the foam product can be removed from the frame.

Further, it is preferable that the lower end of the frame 3 is located near the pedestal 1. This makes it possible to press and compress the foam product P without lateral deformation until it reaches the vicinity of the pedestal. Further, since a gap is provided between the frame 3 and the pedestal 1, as shown in FIG. 1A, the upper packaging material film 5 covered on the foam product
Can be extended outside between the lower end of the frame and the pedestal 1 before pressing the foam product, and the ends of the outwardly extended film are attracted to each other from, for example, two or four directions. Thus, it is possible to press the foam product P in a state where the upper packaging film 5 is applied with an appropriate tension. And if at least an appropriate tension is applied to the outer wrapping film 5 in the outward direction,
As shown in FIG. 1 (b), the film is pulled out in the circumferential direction with the progress of the pressing of the packaging, and as shown in FIG. The compression and compression of the foamed product can be performed without any adverse effect, and the compression and compression of the foamed product can be performed without wrinkles occurring in the packaging film.

However, the upper packaging material film does not always have to pass through the space between the lower end of the frame and the pedestal. For example, as shown in FIG.
The upper wrapping material film 5 is extended outward from the upper end of the frame 3, and in this state, the foam product P is pressed and compressed, and foamed to an appropriate state as shown in FIG. After compressing the body product P, the foamed product P pressed together with the upper packaging material film 5 by moving the frame 3 upward, opening the frame 3, or combining the opening and the movement of the frame 3. Then, as shown in FIG. 2C, the upper wrapping material film 5 may be extended in all directions, and may be overlapped with the lower wrapping material film 4.

After the foam product is pressed and compressed to an appropriate degree in this way, the upper packaging film 5 and the lower packaging film 4 are overlaid, and the periphery thereof is heated, for example, by a heating medium or high-frequency heating. The compressed foamed product is fixed by heat sealing using, for example, and sealed, and the packaging is completed. At this time, part of the heat sealing is not performed, and the air inside the package is sucked from the unsealed part, or by performing further pressing together with the air suction, the degree of compression is increased, and the thickness is reduced. It is also possible to obtain a compression-packed foam product which is somewhat reduced in the transverse direction. The fixation of the wrapping material may be performed, if possible, when the compressed foam product is in the frame or after being released from the frame.

At this time, a bag-shaped material may be used as the upper and lower film-like packaging materials instead of the vertically divided film. Further, a film provided with a fastener (such as a slide fastener) may be used as the packaging film or bag. For example, when a synthetic resin bag with a zipper is used as a packaging material, after a predetermined pressing and compression, and if necessary, a suction compression in the bag, the outside of the zipper is heat-sealed. And seal. If the package is provided with a fastener, the foam product can be restored by cutting and opening the outer portion of the fastener when the package is opened, and the restored foam product can be compressed. Stored in the bag again in the opened or restored state, compressed using a plate, etc., and closed the zipper to close, if not to the compressed state before opening Packaging of foam products that have been compressed down to storage for reuse,
Alternatively, it can be provided on portable flights.

In the above example, the packing material is fixed and sealed by heat fusion. However, the sealing of the package may be performed by an appropriate method such as by using an adhesive. In the case where the height of the foamed product is not so large and the lateral deformation is not so large at the time of the compression, the compression can be performed without using the frame at the time of the compression.

The packaging material used in the packaging method of the present invention comprises:
A film formed of highly airtight plastic is preferred. As such a plastic material, any material such as polyvinyl chloride, polyethylene, polypropylene, polyvinylidene chloride, polyester, and nylon can be used. These resins may be a single-layer film or a laminate film of two or more layers made of different resins. Of course, it may be in a bag shape. Also, by using a film that is easily torn in one direction as the film to be used, the package can be easily opened,
It is usually preferred to use such a film.

In the case where the packaging is performed without sucking the air in the package, airtightness may not be required. In such a case, the film-like material (packaging material) is not required to have the above-mentioned structure. Not metal products, but metal sheets,
It may be paper or cloth. In the present invention,
The packaging material may be any as long as the foam product is compressed and stored, and can be opened when necessary to restore the foam product. Therefore, in some cases,
The packaging material may be a can, bottle or box. Any material such as metal, plastic, glass, paper, and corrugated cardboard can be used as the material for these cans and boxes. Also,
When the packaging material is a can, bottle, box, or the like, the seal is usually made with a lid. As such a lid, a conventionally known sealing method such as a screw-type lid, a pull-top lid, or a lid without a screw may be fixed with an adhesive tape.

The restoration speed of the foam product is determined to some extent by the material used and the compression method such as the resin material used for the foam, the foaming method, the degree of foaming, the size or compression strength of the cells, and the compression speed. Would be done. Depending on the intended use, quick opening of the package and resilience of the foam product may be required. In such a case, for example, as shown in FIG. 3, as a wrapping material, a film 5 in which, for example, a fracture 6 in the form of X is previously attached, and the X fracture is adhered with a separately prepared adhesive tape 7 is used. By preparing and using it for compression packaging, a faster restoration of the foam can be achieved. That is, as shown in FIG. 3, when the portion to which the X-shaped fracture is bonded is positioned so as to reach almost the end of the upper surface of the compressed package, the edge of the adhesive tape is pulled at the time of opening to open the package. By performing the opening, the torn place spreads at a stretch by the restoring force of the foam, and is quickly reopened. This allows the foam product to be reopened more quickly than if simply opening the side portion of the compressed package. In addition, since the opening of the package is quickly performed, the restoration of the foamed product is also quick. The shape of the crack is not limited to the X shape as shown in FIG. 3, but may be any shape such as a cross shape, a circle shape, or a shape similar to the shape of a compressed foam product.

The restoration of the foamed product can be performed more quickly by using a restoration aid or the like. FIG. 4 shows an example. In FIG. 4, a cavity 8 is provided in the foamed product P, and a shape memory alloy or a spring 9 or the like is built in the cavity 8 as a restoration aid. By doing so, for example, as the packaging material, an X-shaped cut (split) is formed on the upper surface, and this is wrapped using a packaging material adhered with an adhesive tape. When the end is pulled and opened, the foam product rises in a state where the foam product is instantaneously restored and pops out by adding the function of the restoration auxiliary material, which can surprise and impress the opened person. Therefore, it is suitable for dolls such as animals and monsters made of foam, stuffed animals, and products for uses such as playground equipment, playground equipment, and toys. Further, a water-absorbing material whose volume increases due to the absorption of moisture can be used as the restoration auxiliary material. Foam products containing a water-absorbing material include mixing the water-absorbing material into the resin for the production material during the production of the foam product, or treating the foam product after the foam product has been manufactured to contain the water-absorbing material. It can be manufactured by a method, or a method in which a hollow portion is formed inside a foamed product, and a water absorbing material is stored therein. The foamed product containing this water-absorbing material increases the area of the water-absorbing material by natural moisture absorption after opening the packaging material or by being put into water, and can be quickly restored. As the water-absorbing material, for example, a water-absorbing polymer whose volume is greatly increased by water absorption is preferably used. Also, by mixing or containing the carbon dioxide gas generating material in the foamed product, it is possible to generate carbon dioxide gas by moisture absorption at the time of opening, and to quickly restore the foamed product.

Further, the water-stopping material is a barrier material for preventing water leakage or outflow from pipes or the like for the time being, or for absorbing leakage or spilled water, and preventing ingress of water that has come out such as sandbags. It is used as
When utilizing a foam product for such a purpose, the foam to be used may be composed of only a foam without using a water absorbing material or the like, but a resin composition mixed with a water absorbing material or if possible Use a foam made from a water-absorbent resin, or make a foam contain a water-absorbing material after producing the foam, and further form a cavity inside the foam and store the water-absorbing material in it. It is preferable to use a foam produced by the method. For example, a foam containing or absorbing a water-absorbing material is compressed and packed by the method of the present invention and stored, and when water or water leaks from the piping, the bag is broken at the water or water leaking place. Re-opened and wound around the water discharge or leak point, the foam expands rapidly due to the water absorption capacity of the foam itself and the water absorption capacity of the water absorbing material, and the water stop or water leak point is pressed by the water stop material. Water can be shut off. In addition, if the compressed and taken out waterproof material is placed on the leaked water or the spilled water, the water is absorbed immediately. With the waterproof material used for repairing water leakage from conventional pipes, water that has already leaked due to water leakage and the like cannot be removed, but with the waterproof material of the present invention, water that has already flowed can be simultaneously absorbed. Water that has already leaked can also be quickly removed using the same material, and the effect that secondary damage due to water leakage and the like can be minimized can also be achieved. Further, since the water-stopping material increases in weight by absorbing water, it can be used as a waterproof wall instead of a sandbag as described above. For example, when used as a waterproof wall, the foam is considerably large, so if it is compressed and packaged by the method of the present invention, it can be stored, stored, carried,
Considerable convenience is obtained in transportation and the like.

The water-stopping material is a foam as described above,
Preferably it may be made of a cubic foam,
The foam may be stored in a water-permeable or perforated outer packaging material. An example is shown in FIG. In FIG. 5A,
A water-blocking material (waterproof wall) W which can be used in place of a sandbag, which is compressed and packaged, is shown. The waterproof material W is a foam P
A foam product containing a water absorbing material 10 in a part of the cavity 8 is put into an outer packaging material 11 having a bellows-like structure, and this outer packaging material is pressed and compressed together with the upper and lower films 4 and 5 and then the upper and lower films It is manufactured by heat sealing a film. When using the packaging film 4,5
When the water-stopping material W which has been compressed and packaged is taken out and placed in a place where it is desired to prevent the intrusion of water, the water-stopping material W absorbs and expands due to, for example, discharged water, and immediately as shown in FIG. 5 (b). The foam is restored to its original size. In addition, the weight of the waterproof material increases due to water absorption, and functions as a waterproof wall. Further, the outer wrapping material 11 of the water-stopping material is provided with a tongue portion 12 and the hole 13 is provided in the tongue-out portion 12, so that the water-stopping material can be fixed with a pile or connected with a string. In this example, a bellows-type bag is used as the outer packaging material, but it goes without saying that a non-bellows-type bag may be used.

The base material of the water-stopping material may not be a foam, but may be a cloth, a nonwoven fabric, a corrugated sheet material, paper, or the like. FIG. 6 shows a corrugated sheet material 1.
4 shows an example of a waterproof material using No. 4. The water-stopping material shown in FIG. 6 has a structure in which a large number of holes 15 are formed on both sides and the inside is filled with a water-absorbing material 10.

The foam product to be packaged in the present invention may be any foam product which has been described above or not specifically described but is conventionally known. . For example, mats to be laid for the purpose of sitting on chairs and floors, back mats, mats to be laid on the floor for purposes other than sitting (eg, bedding, carpets, gym mats,
Such as leisure mats), sound-proof or vibration-proof mats, mannequins that are attached to walls or used as part of wall materials
Foam products that imitate humans, animals and monsters, such as stuffed toys, foam products with characters, foam jump boxes, playground equipment (such as dice, soccer balls, etc.), hydroponic beds, waterproof materials, Cup for warming and cooling water for drinking water,
Bottle keeper, foam for packing, other, packaging, packing,
For baggage (for example, underlaying mail boxes, sticking in containers, lining of attache cases, protective cushioning materials for glass, tableware, ceramics, medical equipment, musical instruments, etc., core materials for handbags, etc., for vehicles and ships (for example, automobiles, trains, Interior materials for ships, sound absorption in engine rooms, vibration damping materials, packing materials, etc.), civil engineering,
