  As shown in FIG. 3, the liquid holding body 2 is formed of a non-woven sheet, and the periphery thereof is thermally welded to the container wall of the container body 1.

  A porous body 3 that adjusts the size of bubbles generated by the liquid holding body 2 is disposed inside the outlet chamber 5. The porous body 3 divides the inside of the outlet chamber 5 into a front chamber 6 facing the liquid holding body 2 and a rear chamber 7 facing the bubble outlet 8.

  As shown in FIG. 1, the porous body is composed of a porous film 3 in which a group of adjustment holes 11 are formed in a plastic sheet, and its peripheral edge is thermally welded to a container wall facing the outlet chamber 5.

  A notch 12 for starting breakage is formed on the periphery of the container body 1 facing the outlet chamber 5. The ear piece 13 facing the notch 12 is grasped, and the container wall facing the outlet chamber 5 is broken to form the foam outlet 8 (see FIG. 5).

  As shown in FIG. 7, an outlet passage 35 having a passage width smaller than the chamber width of the outlet chamber 5 is formed in the outlet chamber 5. The ear piece 13 facing the notch 12 is grasped, and the container wall facing the outlet passage 35 is broken to form the foam outlet 8.

  As shown in FIG. 9, a plurality of damming portions 40 that dam the bubbles that flow into the outlet chamber 5 are formed in the middle of the outlet chamber 5. A bubble passage 41 is formed between the damming portions 40 adjacent in the width direction.

  As shown in FIGS. 10 to 12, a partition portion 42 is formed in the outlet chamber 5 to increase the flow path length of the foam flowing into the outlet chamber 5, and foam passages 43, 44, and 45 are formed above and below the partition portion 42. To do.

  As shown in FIG. 6, the liquid holder 2 and the porous membrane 3 are arranged adjacent to each other with no gap therebetween, and the front wall of the container wall facing the upper and lower edges of the liquid holder 2 and the upper and lower edges of the porous membrane 3. Heat welded to 1a. The upper and lower middle portions of the liquid holding body 2 and the upper and lower middle portions of the porous film 3 are thermally welded to the rear wall 1b of the opposing container wall. A first bubble chamber 31 is formed between the front wall 1a of the container wall and the liquid holding body 2, and a second bubble chamber 32 is formed between the rear wall 1b of the container wall, the liquid holding body 2 and the porous membrane 3, A third bubble chamber 33 is formed between the front wall 1 a of the container wall and the porous membrane 3.

  In the disposable foam generating device according to the present invention, the liquid holding body 2 impregnated with the foam stock solution is enclosed in the container body 1, and the inside of the container body 1 is filled with the gas chamber 4 and the outlet chamber 5 by the liquid holding body 2. It was made to classify. When using the foam generating tool, the container wall facing the outlet chamber 5 is broken to open the bubble outlet 8, and the container wall facing the gas chamber 4 is pressed to cause the gas in the gas chamber 4 to be transferred to the liquid holder 2. The bubbles are generated while the gas in the gas chamber 4 passes through the liquid holding body 2, and the generated bubbles are sent out from the bubble outlet 8. According to such a foam generating tool, the user himself / herself can generate foam for one time without excess and deficiency, and the generated foam can be picked up. Therefore, compared with the conventional foaming tool capable of repeatedly generating foam, The generator can be used hygienically by only a single user. Moreover, it can also be solved that bubbles are unnecessarily generated and the foam stock solution is wasted.

  According to the foam generating tool sealed in the interior of the container body 1 in a state where the gas chamber 4 is filled in advance, the container wall facing the gas chamber 4 is only pressed with the foam outlet 8 opened. Can immediately generate foam. Therefore, it is possible to easily clean the hands and face using the fresh foam immediately after generation. In addition, since the foam generating tool in which the gas is pre-filled in the gas chamber 4 is sealed in an individual package shape, when a foam-type product is newly released, it can be taken home as a free sample and foamed at home. You can try out the quality and function of. In addition, it is possible to carry the necessary number of foam generating tools and perform hand washing, face washing, etc. using the foam that is used at work or travel destination. Furthermore, as with disposable toothbrushes at inns, etc., it is sufficient to prepare the necessary number of types of foam generating tools in each room and have the guests use them freely. It can be omitted. If the gas chamber 4 is filled with air, it is preferable in terms of cost and usability as compared with the case where nitrogen gas or carbon dioxide gas is filled.

  In the foam generating device in which the check valve 47 is arranged at the periphery of the gas chamber 4, since the exhaled air is blown into the gas chamber 4 from the check valve 47 during use, the gas chamber 4 is filled with the exhaled gas. There is no need to pre-fill the gas. Therefore, the space occupied by unused foam generators can be remarkably reduced, and when foam generators are distributed, they should be handled in a state in which a large amount of foam generators are contained in a certain size packaging box or bag. Can do. In addition, the bubble generating tool can be manufactured at a lower cost by the amount that omits the step of filling the gas chamber 4 with gas in advance. In the case of using a foam generating tool, it is only necessary to blow in exhaled air from the blowing port 48 to fill the gas chamber 4, so that the preparation work required for generating the foam lump can be simplified and the lather can be easily generated.

  In the foam generating tool in which the gas generating tool 53 is sealed in the gas chamber 4, the first bag 54 and the second bag 55 are ruptured by squeezing the container wall facing the gas chamber 4 at the time of use, so that carbon dioxide gas is generated. The gas chamber 4 can be filled and generated. Moreover, since it is not necessary to fill the gas chamber 4 with a gas in advance, the space occupied by the unused foam generating tool can be reduced. Furthermore, since the first bag 54 and the second bag 55 can be ruptured during use and the gas chamber 4 can be immediately filled with the carbon dioxide gas, the preparatory work required for the generation of the foam lump can be simplified and the lather can be easily generated. .

  When the liquid holding body 2 is formed of a non-woven sheet, the degree of air permeability and the size of the generated foam can be freely adjusted by adjusting the entangled state of the material fibers. Further, compared with the case where the liquid holding body 2 is formed of, for example, a sponge sheet, a fiber mat, or a net, the foam stock solution can be uniformly impregnated and held over the entire sheet surface. Bubbles can be generated. Moreover, since the sheet | seat made from a nonwoven fabric can be heat-welded easily to the container wall of the container main body 1, it is excellent in mass-production effect and can provide the disposable foam production | generation tool at lower cost.

  According to the foam generating tool in which the porous body 3 is arranged inside the outlet chamber 5, the size of the foam generated by the liquid holding body 2 and passing through the porous body 3 is adjusted, and the foam outlet is discharged from the rear chamber 7. 8 can be sent. Therefore, it is possible to generate a foam having a fine texture and a high density as compared with a foam generating tool not provided with the porous body 3.

  When the porous body is composed of a porous film 3 in which a group of adjustment holes 11 are formed in a plastic sheet, the porous film 3 has passed through the porous film 3 by changing the hole diameter of the adjustment holes 11 or the adjacent pitch. The size, density, or viscosity of the bubbles can be adjusted. Further, since the porous film 3 formed of a plastic sheet can be easily heat-welded to the container wall of the container body 1, it is excellent in mass production effect and can provide a disposable foam generating tool at a lower cost.

  According to the foam generating tool in which the notch 12 for starting breakage is formed on the periphery of the container body 1 facing the outlet chamber 5, the ear piece 13 facing the notch 12 is grasped and the container wall facing the outlet chamber 5 is broken. Since the bubble outlet 8 can be opened, the preparatory work for bubble generation can be simplified and a bubble lump can be generated easily.

  According to the foam generating tool in which the outlet chamber 5 has an outlet passage 35 having a passage width smaller than the width of the outlet chamber 5, the foam filling the outlet chamber 5 is squeezed by the outlet passage 35 to increase the density of the bubbles. Furthermore, since the foam having a higher density can be directly applied along the skin surface while squeezing out from the outlet passage 35, there is no waste. Therefore, the foam can be easily distributed to the skin surface with less effort. At the time of use, the foam outlet 8 can be opened by grasping the ear piece 13 facing the notch 12 and breaking the container wall facing the outlet passage 35, so that the preparatory work for taking out the foam can be performed easily.

  According to the foam generating device in which a plurality of damming portions 40 are formed in the middle of the outlet chamber 5 and the bubble passage 41 is formed between the adjacent damming portions 40, the liquid flows from the liquid holding body 2 to the outlet chamber 5. The foam can be dammed by the damming portion 40 and forced to pass through the foam passage 41, and the foam can be compressed during that time to increase the density of the foam.

  According to the foam generating tool in which the partition portion 42 that increases the flow path length of the foam is formed in the outlet chamber 5 and the foam passages 43, 44, and 45 are formed above and below the partition portion 42, the liquid flows from the liquid holder 2 into the outlet chamber 5. Most of the bubbles can flow along the partition 42. The bubbles that flow along the partition portion 42 are guided to flow into the bubble passages 44 and 45 below the partition portion 42, and the bubbles are mixed and compressed while flowing through the bubble passages 44 and 45. Therefore, the density of the bubbles can be increased by the amount that the flow path length of the bubbles is large.

  According to the foam generating tool in which the first bubble chamber 31, the second bubble chamber 32, and the third bubble chamber 33 are formed along the liquid holding body 2 and the porous membrane 3, the bubbles and gas filled in the first bubble chamber 31 are Since the bubbles are generated again after passing through the lower half of the liquid holding body 2, the density of the bubbles reaching the second bubble chamber 32 can be increased. In addition, when the bubble filled in the second bubble chamber 32 flows into the third bubble chamber 33 and flows out from the third bubble chamber 33 to the subsequent chamber 7, the size of the bubbles passes through the porous film 3. Adjusted. Therefore, a foam lump composed of finer foam F can be formed at the foam outlet 8.

(Example 1) FIG. 1 thru | or FIG. 4 has shown Example 1 of the disposable foam production | generation tool which concerns on this invention. In the present invention, front / rear, left / right, and upper / lower follow the cross arrows shown in FIGS. 2 and 3 and the front / rear, left / right, and upper / lower displays shown in the vicinity of the cross arrows. In FIG. 2, a foam generating tool includes a liquid holding body 2 impregnated with an appropriate amount of foam stock solution in a container body 1 that is vertically long, and a porous film (porous) that adjusts the size of the foam generated by the liquid holding body 2. Body) 3 and air (gas) are enclosed. The container body 1 is formed in the shape of a vertically long bag made of a plastic sheet or laminate sheet that can be thermally welded or ultrasonically sealed. The interior of the container body 1 is a liquid holding body 2 and an upper air chamber (gas chamber) 4. And outlet chamber 5 (see FIG. 3). The air chamber 4 is pre-filled with air, so that the container wall facing the air chamber 4 is expanded in an outward bulging shape. The inside of the outlet chamber 5 is a porous membrane 3 and is divided into a front chamber 6 facing the liquid holding body 2 and a rear chamber 7 facing the bubble outlet 8. The plastic sheet includes a plastic film. In addition, the container main body 1 may be formed by gluing and bonding a raw material sheet, in addition to forming a plastic sheet by heat welding or ultrasonic sealing.

  The material for forming the container body 1 may be any material that does not leak the contents and can be easily compressed and deformed by applying force from the outside. Polyamide, polyethylene terephthalate (PET), vapor-deposited PET, polypropylene, or aluminum laminated sheet Any one of the above can be applied.

The liquid holding body 2 is formed of a non-woven sheet that can be thermally welded, and its four peripheral edges are thermally welded to the container wall of the container body 1. Non-woven sheet constituting the liquid holding body 2 is made of any one material fiber such as acrylic, aramid, olefin, cupra, polyamide, vinylon, polyester, polypropylene, cotton, rayon, composite fiber, spunlace method, melt blown law, thermal bonding, or can apply a chemical bond method formed by such nonwoven fabric, basis weight is preferably in the range of 20 to 200 g / ^{m 2,} more preferably 50 to 150 g / ^{m 2.} In this example, in order to impregnate a single foam stock solution, a liquid holding body 2 having a vertical and horizontal dimension of 50 × 40 mm was formed using a nonwoven fabric sheet having a weight of 70 g / m ² . The foam stock solution to be impregnated in the liquid holding body 2 should be particularly limited as long as it is normally used for foaming, such as body soap, face washing liquid, hand soap, dish detergent, shampoo, shaving liquid, wasted shaving, hair styling. For example, when a liquid hand soap is used as a foam stock solution, the liquid holder 2 may be impregnated with 1.5 mL of the hand soap.

  The left and right side edges of the liquid holding body 2 are sandwiched between the left and right side edges of the front and rear walls 1a and 1b of the container body 1 and are heat-welded together with the front and rear walls 1a and 1b. As shown in FIG. The upper edge is thermally welded to the front wall 1a of the container body 1, and the lower edge of the liquid holding body 2 is thermally welded to the rear wall 1b of the container body 1. In this way, by thermally welding the upper and lower edges of the liquid holding body 2 to the front and rear walls 1a and 1b of the container body 1, the liquid holding body 2 can be made while sufficiently increasing the ventilation area of the liquid holding body 2. Along with the front and rear walls 1a and 1b, the container wall for storing the liquid holding body 2 can be prevented from greatly expanding.

  The porous film 3 is made of a plastic sheet such as a biaxially stretched polypropylene film (OPP), a non-axially stretched polypropylene film (CPP), a vinyl chloride resin sheet, an acrylic resin sheet, a phenol resin sheet, or a urea resin sheet. A group of adjustment holes 11 are formed in a matrix on the surface. By changing the hole diameter and adjacent pitch of the adjustment holes 11 to be larger or smaller, the size, density, or viscosity of the bubbles after passing through the porous film 3 can be adjusted. In this embodiment, the hole diameter of the adjustment hole 11 is 0.3 mm, and the adjacent pitch is 3 mm. The adjustment holes 11 do not have to be formed in a matrix, but may be formed randomly or in a honeycomb structure.

  The volume of the air filled in the air chamber 4 may be an amount capable of foaming the entire amount of the foam stock solution impregnated in the liquid holding body 2. For example, the liquid holding body 2 is impregnated with 3 mL of hand soap. In that case, the air chamber 4 may be filled with 10 mL of air. By compressing the container wall facing the air chamber 4 and causing most of the air in the air chamber 4 to flow toward the outlet chamber 5, while the air pushed out of the air chamber 4 passes through the liquid holding body 2, the foam stock solution Can form bubbles on contact. Moreover, after the foam extruded from the liquid holding body 2 fills the front chamber 6, the foam is extruded from the adjustment hole 11 of the porous film 3 and flows to the rear chamber 7.

  The unused foam generating tool is sealed by heat-sealing the three surrounding sides, and the foam outlet 8 can be opened only after the container wall facing the outlet chamber 5 is broken. In order to facilitate such breakage of the container wall, a notch 12 for starting breakage is formed on one side edge (periphery) of the container body 1 facing the outlet chamber 5. In the case of breaking the container wall, the bubble outlet 8 can be opened by grasping the ear piece 13 below the notch 12 to break the heat-welded portion and further breaking the container wall facing the outlet chamber 5. For example, when the container wall is broken in a state of crossing the container wall in the width direction as shown in FIG. 5, the bubbles F exposed from the bubble outlets 8 having the same lateral width as the rear chamber 7 of the outlet chamber 5 can be picked up. In addition, you may cut | disconnect a container wall diagonally with scissors and open the bubble outlet 8 of a favorite magnitude | size.

  The foam production | generation tool comprised as mentioned above can be manufactured through the process shown, for example in FIG. In FIG. 4, reference numeral 15 is an original fabric roll of a plastic sheet that forms the container body 1, 16 is an original fabric roll of a nonwoven fabric sheet that forms the liquid holding body 2, and 17 is an original fabric roll of the porous film 3, which is adjusted in advance. A hole 11 is formed. The plastic sheet is fed out from the raw roll 15 and folded in half, and the nonwoven fabric sheet and the porous film 3 are sandwiched between them and fed to the primary weld 18. Three pairs of heating rollers 19 and receiving rollers 20 are provided in the primary welding portion 18, and roller pairs at both ends of these roller pairs are in contact with the upper surface of the plastic sheet in which the heating rollers 19 are folded in half. . The central roller pair is in contact with the lower surface of the plastic sheet in which the heating roller 19 is folded in half.

  While passing through the primary weld 18, the upper edge of the liquid holder 2 and the lower edge of the porous film 3 are thermally welded to the front wall 1 a of the container body 1, and the lower edge of the liquid holder 2 and the porous film 3 are further welded. Are simultaneously welded to the rear wall 1b of the container body 1. In the primary welding portion 18, the plastic sheet on the side in contact with the heating roller 19, the liquid holder 2 and the porous film 3 are merely heat-welded, so that the front and rear walls 1 a and 1 b of the container body 1 are heated. It is not welded. The plastic sheet delivered from the primary welded portion 18 is thermally welded at the secondary welded portion 21 at portions corresponding to the left and right side edges of the container main body 1, and the heat welded portion is further cut with a cutter. 22 is formed. A portion thermally welded by the secondary welding portion 21 is denoted by reference numeral 23. The obtained blank 22 is impregnated in the liquid holding body 2 by injecting the foam stock solution 25 from the upper edge opening of the air chamber 4 in the liquid filling section 24. Furthermore, air is filled in the air chamber 4 in the gas filling section 26, and the opening at the upper edge is thermally welded to complete the foam generating tool. Reference numeral 27 denotes a heat-welded portion at the upper edge of the air chamber 4.

  When using a foam production | generation tool, as shown in FIG. 5, the container wall which faces the exit chamber 5 is fractured | ruptured, and the foam outlet 8 is opened. In this state, the container wall facing the air chamber 4 is crushed to flow the air in the air chamber 4 toward the outlet chamber 5. The air pushed out from the air chamber 4 comes into contact with the foam stock solution while passing through the liquid holding body 2 to become bubbles and fills the front chamber 6. Further, the foam in the front chamber 6 is extruded from the adjustment hole 11 of the porous film 3 to become a foam F whose size is adjusted, flows into the rear chamber 7, and protrudes outside the foam outlet 8 to form a large foam mass. Thus, the user can take out the foam. Further, by squeezing the container wall facing the liquid holding body 2 toward the bubble outlet 8, the bubbles remaining in the front chamber 6 and the rear chamber 7 are exposed from the bubble outlet 8, and the final bubbles are taken out without waste. be able to. The time from crushing the container wall facing the air chamber 4 to the formation of the foam mass outside the foam outlet 8 is very short, and the foam mass can be formed in an instant. The container body 1 after the foam is generated is discarded as burning garbage.

  As described above, according to the disposable foam generating device of the first embodiment, by adjusting the amount of air filled in the air chamber 4, the amount of impregnation of the foam stock solution into the liquid holding body 2, etc. It is possible to produce foams that are suitable for the amount of use. For example, when the hand soap solution is impregnated in the liquid holding body 2 for hand washing, the amount of foam necessary for one hand washing can be generated, so that it is possible to eliminate wasteful consumption of the foam stock solution. In addition, since each container is used up, there is no room for foreign matter and dirt to be mixed into the foam, and the foam can be used in a sanitary manner.

  In addition, since the foam generating device is hermetically sealed, when a foam-type product is newly released, it can be taken home as a sample and the quality and function of the foam can be used at home. Also, since it is a convenient size to carry, you can carry as many foam generators as you need, and use your favorite foam at work or travel to wash your hands or face. Furthermore, as with disposable toothbrushes at inns, etc., it is sufficient to prepare the necessary number of types of foam generating tools in each room and have the guests use them freely. It can be omitted.

(Example 2) FIG. 6: has shown Example 2 of the disposable foam production | generation tool which concerns on this invention. There, the liquid holder 2 and the porous film 3 are arranged adjacent to each other with no gap therebetween, and the upper and lower edges of the liquid holder 2 and the upper and lower edges of the porous film are thermally welded to the front wall 1a of the container wall facing each other. It is. In addition, the upper and lower middle portions of the liquid holding body 2 and the upper and lower middle portions of the porous film 3 are thermally welded to the rear wall 1b of the container wall facing each other. In this way, the first bubble chamber 31 is formed between the front wall 1a of the container wall and the liquid holder 2 by thermally welding the liquid holder 2 and the porous membrane 3 to the front and rear walls 1a and 1b of the container wall. A second bubble chamber 32 is formed between the rear wall 1b of the container wall, the liquid holding body 2 and the porous film 3, and a third bubble chamber 33 is formed between the front wall 1a of the container wall and the porous film.

In the foam generating tool, after opening the foam outlet 8, when the container wall facing the air chamber 4 is crushed, bubbles are generated in the process of the air in the air chamber 4 passing through the upper half of the liquid holder 2. It occurs and fills the first bubble chamber 31. Further, the bubbles filled in the first bubble chamber 31 generate bubbles in the process of passing through the lower half of the liquid holding body 2 to fill the second bubble chamber 32. Further, the bubbles filled in the second bubble chamber 32 pass through the porous film 3 when the bubble flows into the third bubble chamber 33 and when it flows out from the third bubble chamber 33 to the subsequent chamber 7, and the size of the bubbles is reduced. Adjusted. Therefore, a foam lump composed of finer foam F can be formed at the foam outlet 8. Further, since the bubbles and air filled in the first bubble chamber 31 pass through the lower half of the liquid holding body 2 to generate bubbles again, the density of the bubbles reaching the second bubble chamber 32 can be increased. . Since others are the same as the foam production | generation tool of Example 1, the same code | symbol is attached | subjected to the same member and the description is abbreviate | omitted. The same applies to the following embodiments. The disposable foam generating tool 3 of Example 2 was formed by thermally welding the upper and lower edges and the upper and lower middle parts of the liquid holding body 2 to the container body 1 to form the liquid holding body 2 in a V-shaped cross section. No, the upper and lower edges of the liquid holding body 2 and a plurality of portions in the middle of the upper and lower sides are thermally welded to the container body 1 to form the liquid holding body 2 in a Z-shaped or W-shaped cross section, thereby reducing the number of bubble chambers. Can be increased.

(Example 3) FIGS. 7 and 8 show Example 3 of the disposable foam generating device according to the present invention. There, the four peripheral parts of the pair of front and rear plastic sheets 1c and 1d were thermally welded to form a bag-like container body 1. Further, the porous film 3 was omitted, and only the liquid holding body 2 was sealed inside the container body 1. Furthermore, an outlet passage 35 having a passage width smaller than the width of the outlet chamber 5 and a bubble guide edge 36 inclined downward toward the outlet passage 35 are formed in the center of the bottom of the outlet chamber 5. The bubble guide edge 36 is formed by inclining a thermal welding portion 37 when the lower portions of the pair of front and rear plastic sheets 1c and 1d are thermally welded obliquely. In the case of this foam generating tool, the ear piece 13 facing the notch 12 is grasped, and the container wall facing the outlet passage 35 is broken to form the foam outlet 8. As described above, in the foam generating tool of Example 3, since the outlet passage 35 having a small passage width is formed at the bottom of the outlet chamber 5, the foam filled in the outlet chamber 5 is squeezed by the outlet passage 35 to reduce the density of the foam. In addition, the foam having a higher density can be directly spread along the skin surface while squeezing out the foam from the outlet passage 35. Therefore, the foam can be distributed to the skin surface with less effort. In addition, since the porous film 3 is omitted, the structure of the foam generating tool can be simplified by that amount, and the manufacturing cost can be reduced. In addition, the vertical dimension of the container body 1 can be reduced by the amount that the porous film 3 is omitted.

Example 4 FIG. 9 shows Example 4 of the disposable foam generating device according to the present invention. In this case, as in Example 3, the porous membrane 3 was omitted and only the liquid holding body 2 was sealed inside the container body 1. In addition, an outlet passage 35 and a bubble guide edge 36 are formed at the bottom of the outlet chamber 5, and three damming portions 40 that dam the bubbles flowing into the outlet chamber 5 are formed in the upper and lower middle portions of the outlet chamber 5. The damming portion 40 is formed by intermittently heat-welding the front wall 1a and the rear wall 1b of the container body 1, and a bubble passage 41 is formed between the damming portions 40 adjacent in the width direction. It is. As described above, when the damming portion 40 is formed in the outlet chamber 5, the foam flowing into the outlet chamber 5 from the liquid holding body 2 is dammed by the damming portion 40 and forcibly passes through the bubble passage 41. In the meantime, the foam can be compressed to increase the density. Further, the foam having a high density can be directly applied along the skin surface while squeezing out from the outlet passage 35.

(Example 5) FIG. 10: has shown Example 5 of the disposable foam production | generation tool which concerns on this invention. In this case, a partition portion 42 that increases the flow path length of the bubbles flowing into the outlet chamber 5 is formed inside the outlet chamber 5, and bubble passages 43 and 44 having a small passage width are formed above and below the partition portion 42. The upper bubble passage 43 and the lower bubble passage 44 communicate with each other through a bubble passage 41 at the protruding end of the partition portion 42. In addition, the notch 12 was formed obliquely downward so that the lower corner portion of the container body 1 was broken so that the bubble outlet 8 could be opened obliquely. As described above, when the bubble passages 43 and 44 having a small passage width are formed inside the outlet chamber 5, most of the bubbles flowing into the outlet chamber 5 from the liquid holding body 2 pass through the partition portion 42. It can be made to flow toward the mouth 41 and flow guide from the bubble passage 41 to the lower bubble passage 44, and the bubbles can be compressed by the bubble passages 43 and 44 having a small passage width between them to increase the density.

(Example 6) FIG. 11: has shown Example 6 of the disposable foam production | generation tool which concerns on this invention. There, two partition portions 42 are formed above and below the outlet chamber 5 so that the flow path length of the bubbles flowing into the outlet chamber 5 can be further increased. Since the upper and lower partition portions 42 are formed in opposite directions from the left and right side edges of the container main body 1, the three bubble passages 43, 44, and 45 are successively bent in a fold shape from the liquid holding body 2 side. As described above, according to the foam generating tool in which the three foam passages 43, 44, and 45 are formed, the flow path length of the foam becomes long, and when the foam passes through the two foam openings 41, Since it flows and mixes in the opposite direction, high-density foam can be formed uniformly. Further, even when the air chamber 4 is abruptly crushed, the flow of bubbles can be suppressed to some extent by the passage resistance of the bubble passages 43, 44, and 45, so that the bubbles can be prevented from being ejected vigorously from the bubble outlet 8. .

  (Example 7) FIG. 12: has shown Example 7 of the disposable foam production | generation tool which concerns on this invention. There, the jetty-shaped partition part 42 and the upward damming part 40 are provided inside the outlet chamber 5, and the foam passage 44 facing the foam outlet 8 is tapered toward the foam outlet 8. I did it. According to such a foam production | generation tool, the flow path length of the foam in the exit chamber 5 can be lengthened similarly to the foam production | generation tool of Example 5. FIG. Moreover, the cross-sectional area of the bubble channel | path 44 can be made small toward the bubble exit 8, and also the flow direction of a bubble can be forcedly changed and mixed by the upward damming part 40, and the density of a bubble can be raised.

  (Embodiment 8) FIGS. 13 to 15 show Embodiment 8 of a disposable foam generating device according to the present invention. In this case, the check valve 47 is sealed at the heat welding portion 27 at the upper edge of the air chamber 4, and the air chamber 4 can be filled with the exhaled air by blowing the exhaled air from the blowing port 48 of the check valve 47. The check valve 47 is formed by heat-welding the left and right edges of two plastic sheets, and allows inflow of gas, but two sheets facing the air chamber 4 when the air chamber 4 is filled with gas. The plastic sheets can be in close contact with each other to prevent the outflow of gas. In order to open the blowing port 48, a notch 49 is provided in the vicinity of the upper corner of the container body 1.

  When using the foam generating tool, as shown in FIG. 15, the thermal welding portion 27 is broken by grasping the ear piece 50 above the notch 49, and the upper portion of the check valve 47 is broken to make the blowing port 48. Open. In this state, the inhalation is blown into the air chamber 4 with the blowing port 48 added to the mouth to be filled. Next, using the notch 12 as a cutting start end, the container wall facing the outlet chamber 5 is broken to open the bubble outlet 8. In this state, the container wall facing the air chamber 4 is crushed to allow the exhaled air in the air chamber 4 to flow toward the outlet chamber 5, thereby forming a bubble mass at the bubble outlet 8. According to the foam generating tool of Example 8, since it is not necessary to pre-fill the air chamber 4 with air, the space occupied by the unused foam generating tool can be remarkably reduced. It is possible to circulate in a state where a large amount of foam generating tools are accommodated by the packaging box or the packaging bag. Less space is required for storage. Moreover, since it is not necessary to pre-fill the air chamber 4 with air, a foam production | generation tool can be manufactured at less cost. The check valve 47 does not need to be sealed to the heat welding portion 27 at the upper edge of the air chamber 4, and may be fixed to the container body 1 with the blowing port 48 opened. In that case, since it is not necessary to break the upper part of the heat welding part 27 and the check valve 47 and to open the blowing port 48, the preparatory work for foam generation can be simplified and a foam lump can be generated easily.

Example 9 FIG. 16 shows Example 9 of the disposable foam generating device according to the present invention. In this case, the gas generator 53 is sealed in the gas chamber 4 in advance, and the gas generated in the gas generator 53 is filled in the gas chamber 4 when the foam generator is used. The gas generator 53 includes a first bag 54 that contains sodium bicarbonate and citric acid as reaction elements, and contains one of the aqueous solutions, and a second bag that contains the first bag 54 and the remaining reaction element powder. A bag 55 is used. At the time of use, the container wall facing the gas chamber 4 is pressed to rupture the first bag 54 and the second bag 55, and the gas chamber 4 is filled with carbon dioxide gas generated by a chemical reaction between sodium hydrogen carbonate and citric acid. Next, the container wall facing the outlet chamber 5 is opened by opening the bubble outlet 8 with the notch 12 as a cutting start end, and in this state, the container wall facing the air chamber 4 is crushed and the carbon dioxide gas in the gas chamber 4 is discharged. It is made to flow to the chamber 5 side and a foam lump is formed at the foam outlet 8.

  As described above, according to the foam generating tool in which the gas generating device 53 is preliminarily sealed in the gas chamber 4, it is not necessary to fill the gas chamber 4 with air (gas) in advance. The space occupied by can be reduced. Moreover, since the 1st bag 54 and the 2nd bag 55 can be burst at the time of use and a carbon dioxide gas can be immediately filled with the gas chamber 4, the preparatory work required for the production | generation of a foam lump can be simplified and a lump can be produced | generated easily. .
