Description Degassing storage bag Technical field

TECHNICAL FIELD The present invention relates to a deaerated storage bag, and more particularly to a deaerated storage bag capable of storing bulky articles such as a brim and clothing in a compact. Background art

2. Description of the Related Art Conventionally, various degassing storage bags for storing bulky articles such as a futon or clothing have been provided. This type of degassed storage bag consists of a bag made of a synthetic resin film, a bag, clothing, and other items stored in the bag body, and a suction nozzle of a vacuum cleaner inserted through a valve member provided in the bag body. The inside air was evacuated.

However, the conventional degassing storage bag has the following problems. In other words, if a storage material such as a bun is adsorbed on the tip of the inserted suction nozzle, the suction efficiency is reduced, and more time is required for deaeration. In addition, when the resin films of the bag body adhered to each other during suction, the air permeability inside the bag body was hindered, resulting in reduced suction efficiency and residual deaeration.

Therefore, an object of the present invention is to improve the efficiency of suction of air inside the bag body by the suction nozzle, and to provide a deaerated storage bag in which the air permeability inside the bag body is not likely to be partially impaired. is there. Disclosure of the invention

In order to achieve the above object, a deaerated storage bag according to the present invention is made of a synthetic resin film, and has a sealable bag body opening having an opening for taking in and out of storage. A nonwoven fabric made of synthetic fibers provided on the whole or a part of the inner surface of the bag body and having air permeability, and attached to a portion other than the opening of the bag body and facing the nonwoven fabric. An air suction opening member, wherein when the air suction nozzle is inserted into the bag body from the air suction opening member to deaerate the air inside the bag body, the air suction nozzle causes the nonwoven fabric to be formed. A space is formed between the bag and the synthetic resin film of the bag body.

In the degassing storage bag according to the present invention, a nonwoven fabric is provided on the entire surface or a part of the inner surface of the bag body, and the air in the bag body is sucked. When inserted, a space is formed between the nonwoven fabric and the synthetic resin film of the bag body by the nozzle, and the air in the bag body is efficiently sucked by utilizing the air permeability of the nonwoven fabric. be able to. In addition, the non-woven fabric prevents the stored items from directly contacting the tip of the suction nozzle as much as possible, thereby preventing a reduction in suction efficiency. Further, since the nonwoven fabric is sandwiched between the synthetic resin films of the bag body, the films do not adhere to each other particularly near the opening member into which the suction nozzle is inserted, and the air permeability inside the bag body is not particularly large. Is sufficiently retained.

In the degassed storage bag according to the present invention, the air suction opening member is preferably an inverted ji valve made of a synthetic resin film. Such a check valve can be easily manufactured simply by laminating two films and welding or bonding the two sides, and is easy to attach to the bag body and does not become bulky. Further, the check valve made of a film is kept flat by the nonwoven fabric, and the air closing effect is good. BRIEF DESCRIPTION OF THE FIGURES

Hereinafter, an embodiment of a deaerated storage bag according to the present invention will be described with reference to the accompanying drawings.

(See the first embodiment, FIGS. 1 to 4)

As shown in FIGS. 1 (A) and (B), a deaerated storage bag 1 OA according to a first embodiment of the present invention has a bag body 11 composed of two sheets 12 and 13, The bag body 11 comprises a non-woven fabric 15 provided on an inner surface of approximately 1Z3 below the inner surface of the bag body 11 and a check valve 20 for air suction attached to a lower side of the bag body 11. The sheets 12 and 13 are made of a laminated material. The inner surface is made of a heat-sealable synthetic resin film (for example, a polyethylene film or a polypropylene film), and the outer surface is non-ventilated. Synthetic resin film

(Eg, polyethylene terephthalate film, polyamide film). The sheets 12 and 13 have both sides and the lower side welded and closed, and the upper side is an opening 14 for taking in and out of stored items. The welded parts a, a on both sides are shown with diagonal lines in Fig. 1 (A), and the welded part b on the lower side is shown with diagonal lines in Fig. 1 (A). Inside the opening 14 of the bag body 11, a fastener 18 is provided which can be opened and closed over the entire width thereof. The fastener 18 has a concave portion 18a and a convex portion 18b, and is a well-known device having a function of sealing the inside of the bag body 11 when closed, and a slider 19 for facilitating the closing. Is attached.

The nonwoven fabric 15 is a breathable fiber structure made of a synthetic fiber having a heat-welding property, and is provided in approximately one-third of the lower area of the bag body 11, on both sides and the lower side. The parts are welded to the inner surfaces of the sheets 12 and 13, and the other side is welded to the sheet 13. The welded portion c with the sheet 13 is shown by hatching in FIG. 1 (A), and is also shown in FIG. 1 (B).

The check valve 20 is a flat tubular body formed by laminating two synthetic resin films on each other without welding or adhering on both sides, and a sheet 13 and a non-woven fabric 1 are provided at the lower side of the bag body 11. 5 between. When the inside of the bag body 11 is evacuated to almost a vacuum, the two films inserted into the bag body 11 adhere to each other by depressurization, and the check valve 20 Keep the inside airtight. The structure and function of the check valve 20 are described in detail in Japanese Utility Model Registration No. 2502069.

Further, a fastener 21 similar to the fastener 18 is provided inside the outer protruding end of the check valve 20 to ensure the airtightness of the bag body 11 after deaeration. And

In the deaerated storage bag 1 OA having the above-described configuration, the fastener 18 is opened, and the storage objects 30 (see FIGS. 2, 3, and 4) such as a garbage and clothing are bagged from the opening 14. Store it in the main body 11 and close the zipper 18. Then, the air suction nozzle 28 of the vacuum cleaner is inserted into the bag body 11 through the check valve 20 to evacuate the air inside. When deaeration is complete, reverse nozzles 28 Pull out the stop valve 20 and close the zipper 21.

In the deaerated storage bag 1 OA, the nonwoven fabric 15 is provided inside the bag body 11, and the check valve 20 is attached to the portion facing the nonwoven fabric 15, so the inside of the bag body 11 is When the suction nozzle 28 is inserted into the bag body 11 from the check valve 20 to suck / degas the air, the nozzle 28 causes the non-woven fabric 15 to move between the nonwoven fabric 15 and the resin film 13. The space 16 (see FIGS. 2 and 3) is formed, and the air in the bag body 11 can be efficiently sucked. Further, the nonwoven fabric 15 has air permeability in the thickness direction and the plane direction, and the air suction efficiency is good. In addition, as shown in FIG. 3, the stored material 30 is prevented from directly contacting the tip of the suction nozzle 28 by the nonwoven fabric 15, and a reduction in suction efficiency is prevented.

Also, as shown in FIG. 4, even if the resin films 12 and 13 of the bag body 11 try to adhere to each other at the portion where the suction nozzle 28 is inserted, the non-woven cloth 15 is interposed between them. The resin films 12 and 13 do not adhere to each other because they are sandwiched, and the non-woven fabric 15 also has air permeability in the direction perpendicular to its thickness. The properties are maintained, and there are no problems such as inability to deaerate or take time to deaerate.

As described above, maintaining good air permeability inside the bag body 11 has an advantage that degassing can be performed quickly.

In the bag body 11, there is a possibility that the films 12 and 13 may adhere to the remaining about 2/3 of the non-woven fabric 15 where the nonwoven fabric 15 is not provided. Therefore, even if they are partially adhered to each other, a large number of gaps are formed between the stored items 30 and the films 12 and 13 as a whole, and the possibility of impairing air permeability is extremely low. .

By the way, since the nonwoven fabric 15 is a fibrous structure having air permeability, the surface area is much larger than that of the resin film, and antibacterial agents, deodorants, moisture absorbers, and insect repellents If an agent or the like is included in the nonwoven fabric 15, the respective effects can be effectively exhibited.

The configuration of the degassed storage bag 10A can be variously changed. For example, the valve 20 does not necessarily have to function as a check valve, and may be an opening member having a size into which the suction nozzle 28 can be inserted. It is preferable that such an opening member has a structure that can be quickly sealed after deaeration. Further, the mounting position of the check valve 20 and the opening member is not limited to the lower side portion of the bag body 11, but may be a side portion or a flat portion of the bag body 11.

In the degassed storage bag 1OA, the welded portion c between the nonwoven fabric 15 and the film 13 is formed in a line shape. This is to prevent the stored item 30 from entering between the nonwoven fabric 15 and the film 13 and coming into contact with the suction nozzle 28. This object can be achieved even if the welded portion c is formed like a spot. Alternatively, bonding may be used instead of welding. (See the second embodiment, FIG. 5)

As shown in FIG. 5, a degassed storage bag 10 B according to a second embodiment of the present invention is a non-woven cloth 1 having a nonwoven fabric 15 sandwiched between sheets 12 and 13. The storage chambers A, B, and C are constructed by welding the film 5 and the film 13 · in a line at the welding portions c and d. Further, a chamber D is also formed, but this chamber D is a suction chamber to which a suction nozzle is inserted, and is separated from the storage chambers A and B by a welded portion c.

The other configuration of the deaerated storage bag 10B is the same as that of the deaerated storage bag 10A of the first embodiment, and in FIG. 5, the same members and portions as those in FIG. And duplicate explanations are omitted.

The degassing storage bag 10B has the same degassing method and operation and effects as those of the degassing storage bag 1OA, and its changeable form is also the same. In particular, in the degassing storage bag 10B, a large item (eg, a brim) can be stored in the room C, and a small item (eg, clothing) can be stored in the storage rooms A and B separately. Even if compartments A, B, and C are separated, non-woven fabric 15 covers the entire compartment, so each compartment A, B, and C is reliably connected to suction chamber D due to the air permeability of nonwoven fabric 15. Is communicated to.

(See the third embodiment, FIG. 6)

As shown in FIG. 6, a degassed storage bag 10C according to a third embodiment of the present invention has a nonwoven fabric 15 sandwiched between the sheets 12 and 13 to cover the inside of the bag body 11 as shown in FIG. These are roughly divided into storage rooms A and C on the front and back. In other words, the deaerated storage bag 10C is divided into two storage chambers A and C in which the welded portions c and d are omitted in the deaerated storage bag 10B of the second embodiment. It is.

The other configuration of the deaerated storage bag 10C is the same as that of the deaerated storage bag 10B. In FIG. 6, the same members and portions as those in FIG. 5 are denoted by the same reference numerals, and duplicate descriptions are omitted. I do. The degassing method and the effect of the degassing storage bag 10C are the same as those of the degassing storage bag 1OB, and the modifiable form is also the same.

In the deaerated storage bag 10C, if an article is stored in the storage chamber A to the back, the article may be sucked into the suction nozzle inserted from the check valve 20. It is preferable to store large items such as buns and small items such as clothing in Room C.

(Other embodiments)

It should be noted that the degassed storage bag according to the present invention is not limited to the above embodiments, but can be variously modified within the scope of the gist.

In particular, sheets 12 and 13 can use various films other than polyethylene, polypropylene, polyethylene terephthalate, and polyamide, and need not necessarily be a laminate material. Film You may. "

Further, the fastener 18 for sealing the opening 14 can have various configurations. For example, a dubno-reticular system in which concave portions and convex portions are respectively arranged in two rows may be used.

In addition to using a vacuum cleaner as the deaerator, a dedicated air suction device may be used. Industrial applicability
