Description

  The present invention relates to a compression bag capable of compressing a stored item by deaeration in a state in which the stored item such as clothing is stored.

  2. Description of the Related Art Conventionally, there is known a compression bag that can be stored in a compressed state such as a futon or clothing. The compression bag has a structure that allows the internal gas to be extracted (degassed) to the outside while the object to be stored is stored. As a method of use, the object to be stored can be compressed by first storing the object in a compression bag and then forcibly reducing the internal pressure by compressing it with a vacuum cleaner or by hand. By using the compression bag, the volume of the objects to be stored is compressed to about 1/2 to 1/3. Therefore, the storage space may be narrow, and more storage spaces with the same volume may be stored. The stored items can be stored.

  With respect to such a compressed bag, technological development is being promoted for the purpose of easy storage, easy degassing, and further compactness of the objects to be stored. In Patent Document 1, a resin-made bag main body in which an opening for storing a stored item is formed at one edge of the outer peripheral edge, an occlusion device provided on the inner surface of the bag main body, and closing the opening; A compression bag with a deaeration part comprising a resin deaeration part that discharges air inside the bag body, wherein the deaeration part and the bag body are welded at the base end of the deaeration part, A compression bag with a deaeration part is disclosed, wherein the deaeration part has a backflow prevention means for preventing air from flowing back into the bag body.

  The conventional compressed bags were supposed to be used by consumers at home. For example, if the stored items (commodities) are stored in the compressed bags from the production stage and transported, the transportation cost can be reduced. I can expect. Moreover, if the goods are stored and displayed at the store as they are, a large number of products can be stored and displayed in a small place, and the products are not contaminated. Furthermore, when the consumer purchases the product, it is not necessary to repackage it, and of course, the capacity for the consumer to carry can be reduced.

  However, although the capacity of the product is small, it is basically thin, so the size when the consumer carries the product is not so different. In addition, there is a problem that it is difficult to carry a flatly compressed product because it is necessary to pick it with a finger or hold it with an arm.

  Then, an object of this invention is to provide the compression bag which can accommodate a to-be-contained object compactly and can be carried easily.

The compression bag according to the present invention includes a bag body having an opening capable of storing and taking out an object to be stored therein,
A chuck portion capable of sealing and opening the inside of the bag body;
A deaeration part having a check valve capable of releasing the gas existing inside the bag body to the outside in a state where the inside of the bag body is sealed by the chuck part;
It has two stringing holes formed so as not to communicate with the inside of the bag body.

  ADVANTAGE OF THE INVENTION According to this invention, a to-be-contained object can be accommodated compactly, and the compression bag which can be carried easily can be provided.

  A configuration example of a compression bag according to the present invention is shown in FIG. The compression bag shown in FIG. 1 includes a bag body 10 in which two films 11 are overlapped and both side portions and a lower portion are closed by a side seal portion 12 and a bottom seal portion 13 so that an upper portion is an opening portion 14. The bag body 10 basically has a substantially quadrangular shape (including a square shape and a square shape with corners) in a plan view, the three sides of which are closed, and the object 1 to be stored inside from the remaining one opening 14. As long as it is a bag that can be stored and taken out. That is, it is not essential to form two films 11 by overlapping them, and to have the side seal portion 12 and the bottom seal portion 13 themselves.

  As the film constituting the bag body 10, a film formed of a plastic material can be used. Specific examples of plastic materials include polyolefins such as polyethylene and polypropylene; halogenated polyolefins such as polyvinylidene chloride and polyvinylidene fluoride; polyvinyl alcohol; polyamides such as nylon 6, nylon 6,6 and polymetaxylylene adipamide; polyethylene Polyesters such as terephthalate, polyethylene naphthalate, polybutylene terephthalate, polybutylene naphthalate; polyacrylates such as poly (meth) acrylate methyl, poly (meth) ethyl acrylate, poly (meth) acrylate butyl; and these And a copolymer of monomers that form. “(Meth) acryl” means methacryl or acryl.

  Specific examples of polyethylene include linear low density polyethylene, high pressure method low density polyethylene, high density polyethylene, and metallocene polyethylene. Specific examples of polypropylene include a homopolymer of propylene and a random or block copolymer of propylene and ethylene or 1-butene. Specific examples of the copolymer of monomers that form the above-described polymer include ethylene-vinyl alcohol copolymer, vinylidene chloride-acrylic ester copolymer, and the like.

  The film constituting the bag body 10 may be a single layer or may be laminated in two or more layers by coextrusion or the like. In the case of a film laminated in two or more layers, a part of the layers may be a metal layer. The layer formed of the plastic material may be made of an unstretched film, may be made of a uniaxially stretched film, or may be made of a biaxially stretched film. The plastic material may be a gas barrier composite material provided with an inorganic oxide thin film such as aluminum oxide or silicon oxide. This composite material can be obtained by heating and vaporizing a simple substance or a mixture of aluminum oxide or silicon oxide under vacuum, and depositing on a surface of a film or a molded product.

  For example, two sheets of a laminated film obtained by bonding a polyamide film serving as a base material layer and a polyethylene film or a polyethylene terephthalate film serving as a sealant layer are overlapped by bringing the respective sealant layers into contact with each other. It can be set as the bag body 10 which heat sealed the lower part and formed the side seal part 12 and the bottom seal part 13. FIG.

  The seal width of the side seal portion 12 and the bottom seal portion 13 is preferably 1 to 20 mm, more preferably 3 to 15 mm, and still more preferably 5 to 12 mm. The side seal part 12 and the bottom seal part 13 may be completely sealed at room temperature, but may have easy-openability. When the side seal part 12 and the bottom seal part 13 have easy-opening properties, the seal strength under a normal temperature atmosphere is preferably 10 to 30 N / 15 mm, and more preferably 15 to 25 N / 15 mm. The seal strength in a normal temperature atmosphere is a value measured in a normal temperature (23 ° C., 65% RH) atmosphere according to JIS Z0238 “Test method for sealed flexible packaging bags”.

  A chuck portion 21 that can seal and open the inside of the bag body is formed on the upper portion (opening portion 14 side) of the bag body 10. As shown in FIG. 2, the chuck portion 21 can be formed by providing a male chuck 22 and a female chuck 23 on the inner surface of the film 11 constituting the bag body 10. By doing so, in a state where the article 1 is stored in the inside 15 of the bag body 10, the convex portion of the male chuck 22 and the concave portion of the female chuck 23 can be fitted (sealed). . That is, the inside 15 of the bag body 10 can be sealed and opened by the chuck portion 21.

  A check valve 32 for releasing the gas existing in the inside 15 of the bag body 10 to the outside is sandwiched between the bottom seal portion 13, and the portion forms a deaeration portion 31. By doing so, the gas existing in the interior 15 of the bag body 10 can be released to the outside while the interior 15 of the bag body 10 is sealed by the chuck portion 21. More specifically, the container 1 is stored in the interior 15 of the bag body 10, sealed by the chuck portion 21, and in this state, the container 1 is crushed by hand or the like. By releasing the gas existing in the inside 15 of the outside, the object 1 can be compressed and stored compactly. The deaeration part 31 can be formed, for example, on the side opposite to the opening part 14 of the bag body 10, and the chuck part 21 and the deaeration part 31 are formed parallel to each other (may be substantially parallel). preferable.

  The check valve 32 has a function of allowing fluid to pass in one direction but not allowing fluid to pass in the opposite direction. External gas is passed through the check valve 32 to the inside 15 of the bag body 10. It cannot be introduced. The check valve 32 is preferably of a type that does not allow solids such as powder to pass through, and more preferably of a type that does not allow solids and liquids to pass. The check valve 32 is preferably a film, and more preferably a plastic film such as polyethylene.

  The bag body 10 of the compression bag shown in FIG. 1 has string passage holes 41 a and 41 b formed so as not to communicate with the interior 15 of the bag body 10. The stringing holes 41a and 41b are formed as two sets as one set. By carrying out like this, in the state which stored the to-be-contained object 1 compactly, it can carry easily in the state of a handbag or a shoulder cover using the string by tying both ends through a string to two string passing holes. . The string passage holes 41a and 41b may be in any form that allows the string to pass therethrough, and the shape may be circular, elliptical, square, or square with a corner. The stringing holes 41a and 41b may be formed by making a hole at a predetermined position of the bag body 10, or may be formed by a method in which a stringing part produced separately is adhered to the bag body.

  The formation position and the number of the string passage holes can be appropriately selected in consideration of the ease of passing the string, the ease of holding the string through the string, and the like. It is preferable to form two sets of string passage holes on the outer side than 31. In the compression bag shown in FIG. 1, two string passage holes 41 a and 41 b are formed outside the chuck portion 21 and outside the deaeration portion 31, respectively. At this time, when the bag body 10 is folded in two along the fold line X between the chuck portion 21 and the deaeration unit 31, the string passage hole 41 a formed outside the chuck unit 21 and the deaeration unit 31. It is more preferable that at least a part of the string passage hole 41b formed on the outer side overlaps and the string can be passed through the overlapped part. By doing so, it can be folded as shown in FIG. 3, and can be carried more compactly in a state in which the article to be stored 1 is stored.
