Description

Description Liquid bag and liquid bagassembly Technical field

TECHNICAL FIELD The present invention relates to a liquid bag and a liquid bag assembly, and more particularly, to adding moisture (water vapor or atomized water) to a gas such as air, oxygen, nitrogen, carbon dioxide, etc. The present invention relates to a liquid bag and a liquid bag assembly used for a gas water dispenser such as a nebulizer (sprayer). Background art

Conventionally, there has been known a simple oxygen inhaler (wetting device) which can supply oxygen (water vapor or atomized water) to oxygen. In this oxygen inhaler, a reusable cylindrical hard bottle (hard container) is attached with an oxygen introduction pipe, and sterile water is usually injected into the bottle immediately before use.

On the other hand, the oxygen inhaler for medical use is composed of a box-shaped hard bottle (hard container) body, sterile water stored in the bottle body in advance, and an oxygen introduction port sealed at the top of the bottle body. And an oxygen introduction pipe that introduces oxygen introduced from the mouth into the bottom of the container body and couples it in the stored sterile water, and a humidified oxygen sealed at the top of the bottle body. It is mainly composed of an oxygen supply port to be supplied to a predetermined location on the outside. And, a large number of holes are formed in the oxygen introduction pipe.

As mentioned above, simple oxygen inhalers usually require aseptic water to be charged immediately before use, which is troublesome and unsanitary. That is, oxygen conduction There is no guarantee that the sterile condition can be maintained because the inlet or the separately formed inlet for sterile water is opened by hand and sterile water is introduced.

Also, when oxygen is used for underwater publishing with this simple oxygen inhaler or a medical oxygen inhaler, the sound of the bubbling is magnified by resonance because each container body is a cylindrical or box-shaped hard bottle. There was a risk of damaging the outside as noise. Furthermore, the shape of these oxygen inhalers is cylindrical or boxy and bulky, so the manufacturing equipment becomes larger, the manufacturing cost is high, and disposal is inconvenient. Disclosure of the invention

The present invention provides a bag body formed of a flexible thermoplastic resin sheet in a substantially envelope shape, a first port formed in the bag body, and for introducing a gas into the bag body. A gas introduction passage for guiding gas introduced from the part into the liquid accommodated in the bag body, and a second port formed in the bag body for sending out the gas and / or liquid that has passed through the liquid to the outside. Wherein the gas introduction path is formed by partitioning a part of the bag body by heat welding, and has a fine path capable of bubbling a gas introduced through the first opening into a liquid. It is a liquid bag characterized by the following.

That is, according to the present invention, the container for containing the liquid is formed of a flexible thermoplastic resin sheet, the shape of the container is formed substantially in the shape of an envelope, and the gas from the first port is introduced into the liquid. By forming the gas introduction path to be bubbled by heat welding of the facing portion of the thermoplastic resin sheet, gas can be bubbled into the liquid with a very simple structure and the bubbling can be performed quietly. In addition, the manufacturing equipment can be made relatively small, manufacturing costs can be reduced, and disposal after use can be facilitated. Here, publishing of a gas in a liquid involves adding the liquid to the gas (adding moisture or liquid to the gas), increasing the gas saturation in the liquid, stirring the liquid, or mixing the gas with the liquid. Available for mixing.

In the present invention, the gas introduction path has a fine path (fine holes), and the gas introduced through the first port can be finely divided and bubbled into the liquid. Here, these fine paths need only be capable of producing gases and liquids suitable for the purpose of use. For example, when used in a wetter, air or moisture containing moisture (or moisture) suitable for the use is used. Oxygen should just be made.

The gas introduction path having these fine paths is defined by heat welding of the facing portion of the thermoplastic resin sheet, and a heat press of the facing portion is adopted as the heat welding means. In particular, formation of a large number of fine paths is made possible by performing the heat welding intermittently. For example, a non-welded portion having an average road width of 0.5 to 10.0 mm, preferably 0.5 to 3.0 mm is appropriately averaged (center-to-center distance: 0.1 to 100.0 mm, preferably 2. (0-8.0 mm).

The flexible thermoplastic resin sheet is not particularly limited as long as it can be used as a liquid storage bag (bag). Examples thereof include polyethylene resin, polypropylene resin, polyethylene terephthalate resin, and ethylene vinyl alcohol. Resin film or sheet such as copolymer (EVOH resin), and multilayer (laminated) film or sheet such as polyethylene / nylon resin or polyethylene / aluminum foil, with a thickness of 0.1 to 1.00 mm Is mentioned. Among them, it is preferable to use a gas-impermeable material such as a film or sheet of an ethylene vinyl alcohol copolymer or a multilayer film or a sheet of polyethylene / niopene resin, since the oxidation of the content chemical solution can be prevented. Further, the liquid bag according to the present invention Since the is composed of a flexible thermoplastic resin sheet, it is entirely flexible and has a bubbling sound-muffling effect.

In the present invention, the shape of the gas introduction path and the position at which the fine path (micropore) is formed are not particularly limited as long as the gas and / or liquid obtained by bubbling can be used to the intended purpose. The following examples can be given.

(1) Only the descending road (hanging road, the same shall apply hereinafter) has a fine road in part of it.

(2) It consists of a descending road and a crossroad, and has a fine road at least in part of the descending road. (3) It consists of a descending road and a side road, and has a fine road only on the side road.

Here, the example (3) is particularly preferable because the gas to be introduced can be bubbled from the bottom portion of the liquid with a very simple structure, and thereby a high contact efficiency between the gas and the liquid can be obtained.

Further, it is preferable that the gas introduction path is constituted by a tunnel-like space formed in advance so that it can be held in a self-holding manner, so that the gas can be introduced smoothly with reduced resistance. The tunnel-shaped space is not particularly limited, but can be configured to be self-holding in a tunnel shape by heat-treating at least one of the facing portions of the thermoplastic resin sheet. More specifically, the tunnel-like space is used to hold the facing portion of the thermoplastic resin sheet in a tunnel-like manner by heating at least one of the facing portions, and then cooling it (including natural cooling). By doing so, it can be cured and formed to be self-holding. Specifically, a heated fluid (water, air, etc.) is put between facing sheet parts (for example, polyethylene resin or polypropylene resin sheet with a thickness of 80 to 300 mm) or unheated. After adding the fluid, heat it from the outside, or combine these methods as appropriate, and press it from the part other than the tunnel-like space to be made (that is, the part of the bag), It may be formed by holding the relevant part in a tunnel shape and holding it and then cooling it to harden it, or by heating the facing sheet part and expanding it by decompression from the outside, and then holding the relevant part in the same manner. It may be formed by cooling to a temperature and hardening.

In addition, the bag body can be configured to be self-supporting. Specifically, the bag body has a gusset portion formed by folding the bottom of the bag body inward and heat-welding the liquid bag in a pattern capable of imparting self-supporting properties.

Here, a paddle that can provide the liquid bag with self-sustainability is a bottom-shaped or obtuse angle that is low at the center and high toward the side edges.

By forming the V-shaped pattern, the self-sustainability of the liquid bag can be stabilized.

In the present invention, the bag body has a first gusset portion formed by folding an upper portion of the bag body inward and thermally welding the portion constituting the lateral passage of the gas introduction passage, and a lower portion corresponding to the first gusset portion. A second gusset portion formed by folding the bottom portion of the lateral path inward and heat-sealing the first gusset portion, and heat-welding the first gusset portion at both side edges thereof; The edges are overlapped with both side edges of the first gusset portion and heat-welded, each gusset portion is heat-welded in a pattern capable of imparting autonomy to the liquid bag, and the fine path is formed by the second gusset portion. When formed in one gusset, many fine paths can be formed in a wide area, and uniform and active bubbling can be achieved.

In such a double structure having the first and second gusset portions, the second gusset portion is made of a flexible thermoplastic resin sheet which is separate from other portions of the bag body. The first gusset portion is made possible by folding the lower portion inside the lower portion corresponding to the first gusset portion and thermally welding the both side edge portions together with the both side edge portions of the first gusset portion.

Here, in each gusset part, each pattern capable of imparting independence to the liquid bag is a ship-bottom or obtuse V-shaped pattern that is low at the center and high toward both side edges. In addition, the independence of the liquid bag can be stabilized.

[Embodiment 3]

Unlike Embodiments 1 and 2 above, the liquid bag can be made to be self-supporting, and in particular, a gusset in which the bottom portion is folded inward and heat-welded to the portion constituting the horizontal passage of the gas introduction passage A portion may be formed, and both side edges of the gusset portion may be thermally welded in a pattern capable of imparting autonomy to the liquid bag. 7 is a diagram corresponding to FIG. 1 showing a third embodiment of a liquid bag according to the present invention, FIG. 8 is a perspective view for explaining the configuration showing a third embodiment, and FIG. 9 is an enlarged cross-sectional view of a main part showing the third embodiment. FIG. 10 is an exploded view of a sheet material for explaining a method of manufacturing a bag body.

First, in FIG. 79, the wetter 41 as a liquid bag is sealed at the top of the bag body 42 with the bag body 42 and the water (sterilized purified water) W previously stored in the bag body. A first port 43 for introducing oxygen into the bag body 42, a gas introduction path 45 for introducing oxygen introduced from the first port into the water W, and a bag body 4 It is mainly composed of a second port 44 for sending out the hydrated oxygen obtained outside on the water surface, which is sealed at the upper part of 2.

The first port 43 and the second port 44 are integrally formed, but as shown in FIG. 6, these first and second ports are provided with an oxygen supply source (not shown, hereinafter). Similarly, an adapter for communicating with a commercially available connector and another adapter for communicating with the supply destination of oxygen to which water has been added are integrally formed to reduce the number of components. . Other configurations and operations are implemented This is the same as in the second embodiment, and a description thereof will not be repeated.
