Description of the new type [Technical field to which the new type belongs] This creation is about a compression bag with an air suction section, such as a compression bag with an air suction section when compressing a quilt or clothes. [Prior art] Conventionally, it is known that a compression bag with an air suction part is provided with an air suction valve at the end of the bag. When a suction valve is provided at the end of the bag like this, the base end is usually extended from the inside of the bag, the front end is exposed outside the bag, and the main part of the suction valve is fused with the main system of the bag. . In the compression bag with the suction part, the nozzle of the suction pump is inserted into the suction valve, and the air inside the bag is drawn out to compress the storage part. However, in the process for extracting the air inside the bag by the above-mentioned operation, it is necessary to insert the nozzle into the inside of the exhaust valve deeper than the end located inside the bag. It is cumbersome to perform such operations in the state of the contents. And if the inside of the suction valve is coated with an adhesive, the portion of the suction valve that extends to the inside of the outer edge of the bag body will stick to the nozzle, and it will become necessary to lift the nozzle. It is very difficult, and it will damage the suction valve if it is pulled up hard. The purpose of this creation is to provide a compression bag with a suction portion that can evacuate without inserting the nozzle of the pump for suction into the inside of the bag body.

Specifically, the present creation is a compression bag with an air suction portion, which includes a resin bag body formed with an opening portion for accommodating contents on one side of the peripheral edge portion, and is provided inside the bag body. The suction device on the side for closing the opening and the resin suction section for exhausting the internal air of the bag main body are characterized in that the suction section and the suction section are at a base end of the suction section. The main system of the bag is fused together; the above-mentioned air extraction unit has a counter-current prevention means for preventing air from flowing backward into the inside of the main body of the bag. As the engaging tool of the present creation, a sealing zipper including a male member formed in a convex strip shape along the opening edge portion of the bag, and a female member formed in a concave strip shape along the opening edge portion; It is limited to having a male member and a female member, as long as the bag can be sealed and opened and closed. The suction section is not particularly limited as long as it has a structure capable of suctioning air through a nozzle for a suction pump. For example, the suction section can be opposed to the peripheral edge of a bag formed by overlapping two resin films. Things that are open to both edges. As a means of preventing backflow in this creation, it is best to include a one-way valve structure. In addition, a fitting member or the like may be combined in a one-way shutter structure. In addition, the backflow prevention means can be installed anywhere between the base end and the front end of the air suction part. When the one-way valve structure adopts a large member, it is set to prevent the bag thickness direction from increasing. Appropriate near the front end-5- M271832 (3) This work is to fuse the suction part and the bag body at the base end of the resin suction part. Therefore, the base end of the air suction portion does not extend into the inside of the bag, and even when a nozzle such as a pump for suction is inserted into the inside of the bag main body, it is not necessary to insert the nozzle into the inside of the bag main body. Such troublesome homework. This makes it easy to pull out the nozzle after the suction operation, and the suction portion is not damaged during the extraction. The air extraction portion is provided with a backflow prevention means for preventing air from flowing back to the inside of the bag body. When air is extracted from the bag body and compressed, air can be prevented from flowing back to the inside of the bag body, and air extraction can be easily performed. In this creation, the above-mentioned suction unit is arranged near the center of the bag body. In this creation, because the above-mentioned air extraction unit is arranged near the center of the bag main body, when the air inside the bag main body is evacuated, the bag is difficult to deform, so the air is evenly extracted, and the air can be easily evacuated. operation. In other words, if the air suction portion is arranged at the end of the bag main body, the resin film is deformed or decompressed by decompression during the air suction operation, and it is difficult to extract air from the air suction portion The problem can be solved by arranging the air suction part near the center. In this work, the above-mentioned backflow prevention means includes a one-way valve structure. As the one-way valve structure of this work, there is no particular limitation as long as it is a structure for preventing air from flowing into the bag body. For example, a pair of opposite edge portions of the two opposing films are thermally fused together, and the other opposite edge portions of the -6- M271832 (4) are used as openings for exhausting air. In such a film-like shutter structure, air can be exhausted from the inside of the bag, and the films can be tightly sealed to prevent backflow. On the other hand, when the opening of the film-shaped one-way shutter structure is closed with a fitting such as a clip, the compressed state may be maintained even after a long period of time. In this creation, the suction section of the compression bag with the suction section is equipped with a one-way valve structure to prevent air from flowing backward. Therefore, after the air inside the bag body is exhausted and compressed by an exhaust pump or the like, the air can be prevented from flowing back into the bag body, and the bag body can be easily compressed. In the present creation, in the above-mentioned countercurrent prevention means, The male member and the female member are fitted together to seal the inside of the bag main body. As the fitting member of the present invention, for example, a male member made of resin formed into a convex shape and a concave member are formed. A strip-shaped resin female member is fitted together and can be opened and closed, and a zipper band can be opened and closed. For example, a clip band is installed inside the backflow prevention means, or a fitting tool installed outside the backflow prevention means. The construction of the switch and seal is not limited to a particular shape. There is also no limitation on the number of fitting members provided in the suction section, and one or a plurality of fitting members may be used. This creation ’means for preventing backflow, because it has a fitting member, and can maintain the compressed state of the bag body for a long time by fitting the fitting member. And because of the use of a small-sized fitting member, when multiple compression bags with suction parts are stacked and accommodated, even if the fitting member is sandwiched between M271832 (5) of the bag body, it does not take up space, and overlapped storage also Will not damage other bags or suction parts. [Embodiment] The following describes the implementation mode of this creation based on the drawings. [First Embodiment Mode] From Fig. 1 to Fig. 4, it shows the compression bag 1 with a suction part in the first embodiment mode of the present creation.

Near the center of the upper surface sealing portion 1 1 D, the base 1 3 A of the air suction portion 13 is installed, and two dissolving resins-8- M271832 (6) integrated with airtightness are arranged. Manufactured films 1 4 A, 1 4 B. In short, at the base end 13 A of the suction section 13, the suction section 13 and the bag body 10 are fused together. In the above, each of the resin films 1 4A, 1 4B, and 1 4 C is made of a bidirectionally stretched nylon (〇NY) film having air-impermeable properties and a low linear shape constituting an inner layer (adhesive layer). It is composed of a multilayer film of a dense polyethylene (LLDPE) film. As shown in Fig. 1 and Fig. 2, the suction unit 1 to 3 is formed by dissolving two resin films 131 and 132 with the sealing portion 13C, and both edges are opened and formed into a bag shape. As mentioned above, the base end 1 3 A of the air suction portion 13 is installed inside the peripheral edge portion 11 of the bag body χ 〇, that is, the upper surface side of the bag main body 10, and the front end 1 3 B system extends to The vicinity of the peripheral edge portion 11 of the bag body 10. The two thin resin films 1 3 1 and 1 3 2 are usually in a close state. The suction section 1 3 is used for the suction operation. After the suction nozzle of the suction pump is pulled up, the two resin films 1 3 1 and 1 3 2 are quickly adhered to each other. A one-way shutter structure to prevent air from flowing into the inside of the bag body 10. In addition, as a material system of the resin films 1 3 1 and 1 3 2 for forming the air suction portion 13, for example, 1 L D P E can be used. The zipper 12 series, as shown in Figs. 2 and 4, is composed of a male member 1 2 A and a female member 1 2 B, and the male member 1 2 A is fused to the bag body 10. The inner side of the resin film 1 4 A on the surface, 'female member 1 2 B, is melted on the lower side of the bag body 10 to form a -9 * · M271832 (7) on the inside of the resin film 1 4 C on the surface. The male member 1 2 A is provided with a base portion 1 2 1 composed of a fused portion and continuously formed in a band shape, and a convex portion 1 2 2 extending vertically from the base portion 1 2 1 and having a front end portion extending in a width direction. On the other hand, the female member 1 2 B is provided with a base portion 1 2 4 formed by a continuous portion in the form of a fused portion, a recessed portion 1 2 5 integrally formed on the base portion 1 2 4, and the aforementioned raised portion The 1 2 2 series is engaged in the concave portion. The concave portion 1 2 5 is formed by a first claw portion 1 2 5 A which stands on the base portion 1 2 4 and is formed in an arc shape, and a first claw portion which faces the first claw portion 1 2 5 A and is formed in an arc shape. The second claw portion 1 2 5 B is formed. The convex part 1 2 2 of the male member 1 2 A is engaged in the gap 1 2 6 formed by the two claw parts 1 2 5 A, 1 2 5 B, the outer surface of the convex part 1 2 2 and the concave part. Since the inner surface of the portion 1 2 5 is in contact with the surface, it exhibits good air tightness. The material of the zipper 12 can be, for example, the above-mentioned L L D P E. With the structure described above, the use of the compression bag 1 with an air suction portion is performed in the following procedure. First, in a state where the zipper 12 is opened, a storage item 16 such as a quilt is placed inside the bag main body 10, and then the male member 1 2 A and the female member 1 2 B of the zipper 12 are meshed and brought into close contact. And closed up. In this state, a nozzle such as a suction pump is inserted into the bag-shaped suction portion 13 and the air inside the bag main body 10 is discharged to the outside by the suction pump. At this time, the nozzle of the pump for exhaust does not need to be inserted into the deep inside of the bag main body 10, as long as it is slightly inserted into the inside of the bag main body 10 from the base end 1 A of the air suction portion 13. With this operation,-10- M271832 (8) After completely evacuating the air inside the bag body 10 to compress the contents 16 and then pulling out the nozzle of the exhaust pump, the operation is finished. In the suction operation, the resin film 1 3 1 and 1 3 2 used to form the one-way valve structure 15 are inserted through the insertion of the nozzle of the pump for suction, and are separated in the suction section 1 3 A space corresponding to the diameter of the nozzle is formed inside. On the other hand, after the suction operation is completed, when the suction pump nozzle is pulled up, the two resin films 1 3 1 and 1 2 2 are quickly adhered to each other and maintained in a sealed state. In addition, in order to maintain the sealed state for a long time, it is not necessary to close the opening of the suction section 13 with a fitting member. With the first embodiment described above, the following effects can be achieved. (1) At the base end 1 3 A of the suction part 13, fusion of the suction part 13 and the bag main body 10 is performed. Therefore, since the base end 13 A of the suction unit 13 does not extend into the inside of the bag main body 10, even when a nozzle such as a pump for suction is inserted into the inside of the bag main body 10 to perform suction, It is necessary to perform a troublesome operation such as inserting the nozzle of the exhaust pump into a deep place of the bag body 10. (2) Since it is not necessary to insert the nozzle of the exhaust pump into the deep part of the bag body 10, the nozzle can be easily pulled out after the suction operation, and the suction part 1 3 The resin films 1 3 1 and 1 3 2 are not damaged. (3) Because the base end 1 3 A of the air suction part 13 is arranged near the inner edge of the bag main body 10, that is, near the center, when the air of the bag main body 10 is extracted, The body 1 〇 is not easy to change the shape of -11-M271832 (9), so it is easy to evacuate the air evenly, and it is easy to evacuate. In other words, if the suction unit 13 is arranged at the end of the bag main body 10, the resin films 1 4 A and 1 4 C are tightly or deformed by the pressure reduction of the suction operation, and away from the suction unit. It is difficult to extract appropriate air from the place of the air part 1 3. If the air part 13 is set near the center, this problem can be solved. (4) Because the one-way shutter structure 15 is composed of two resin films 1 3 1 and 1 2 2, it does not take up space even when a plurality of compression bags 1 with suction sections are stacked for storage, In addition, the film surfaces of other bags will not be damaged even if they are stacked and stored. (5) Since the one-way valve structure 15 'is provided in the compression bag 1 with the suction part, after the air inside the bag main body 10 is exhausted, the outside air can be prevented from flowing into the inside of the bag main body 10. (6) Because the one-way shutter structure 15 composed of two resin films 1 3 1 and 1 3 2 is used, after the air inside the bag body 10 is exhausted, there is no need to seal it again. The one-way valve structure has 15 operations, and the compression operation is very simple. [Second Embodiment Mode] Fig. 5 shows a compression bag 2 with a suction unit in the second embodiment mode of the present invention. In the following description, only the parts that are different from the first embodiment are described in detail. The same components and the same structural systems are attached with the same drawing numbers, and the description is omitted or abbreviated. -12- M271832 (10) With regard to the compression bag 2 series with an exhaust section of this embodiment, the fitting member 2 5 series is installed inside the vicinity of the front end 1 3 B of the exhaust section 1 3 and the backflow prevention The means, except for the one-way valve structure 15, are the same structure as the first embodiment. The fitting member 2 5 is a zipper-like belt composed of a male member 2 5 A and a female member 2 5 B in the same manner as the zipper 12 provided near the opening 1 1 A of the bag main body 10. The male member 2 5 A has an inner wall surface of the resin film 1 3 1 for forming the upper surface of the suction portion 13, and has a convex portion formed in the width direction from the suction portion 13; the female member 2 5B also has a convex portion formed on the inner wall surface of the resin film 1 3 2 for forming the lower surface and formed in a pair of claw portions. When using the compression bag 2 with an air extraction portion, the same storage contents are contained as in the first embodiment. After the zipper 12 is closed and closed, the nozzle of the air pump is inserted into the air extraction portion 1. 3 inside, and the air inside the bag body 10 is drawn out. With this operation, the air inside the bag main body 10 is completely evacuated to compress the contents 16, and then the male member 2 5 A and the female member 2 5 B of the fitting member 25 are fitted together. It's over. With the above-mentioned second embodiment, in addition to the same effects as the items (1) to (5) of the above-mentioned first embodiment, the following effects can be obtained. (7) Since the one-way valve structure 1 5 uses the fitting member 2 5 ', the sealing performance is improved by the fitting of the male member 2 5 A and the female member 2 5 B> 13- M271832 (11) When the one-way valve structure 15 is used, the compressed state can be maintained for a longer time.
