Description

本発明は、液体を容易に注入可能な風船に関する。 The present invention relates to a balloon into which a liquid can be easily injected.

従来、病院や介護老人福祉施設の従業員が、オムツ交換のトレーニングのために、人体を模した袋状を呈する風船を使用している（特許文献１には、人体を模した袋状を呈する風船が開示されている）。 Conventionally, employees of hospitals and welfare facilities for the elderly have used balloons that imitate the human body for training in changing diapers (Patent Document 1 presents a bag that imitates the human body). Balloons are disclosed).

上記の風船は、気体栓の筒体から空気を吹き込むことで、膨らませることができる。オムツ交換のトレーニングに風船が使用される際には、風船を空気で膨ませた状態で、オムツを風船に取り付ける作業や、風船からオムツを取り外す作業が行なわれる。 The above balloon can be inflated by blowing air from the cylinder of the gas plug. When balloons are used for training in changing diapers, the work of attaching the diaper to the balloon and the work of removing the diaper from the balloon are performed while the balloon is inflated with air.

特開2009-112376号公報Japanese Unexamined Patent Publication No. 2009-112376

ところで空気で膨らませた風船は、重量が軽いため、少しの力で向きが変わってしまう。このため、風船を用いるオムツ交換のトレーニングが、人体に施す実際のオムツ交換から、大きく乖離したものとなり得る（例えば、少しの力で風船の向きを容易に変えることができるため、風船を用いるオムツ交換のトレーニングが、実際のオムツ交換に比して、極めて簡単なものとなり得る）。
By the way, balloons inflated with air are light in weight, so they can change direction with a little force. For this reason, training for changing diapers using balloons can be significantly different from the actual changing of diapers given to the human body (for example, diapers using balloons can be easily changed with a small amount of force. Exchange training can be much easier than the actual diaper exchange).

そこで、風船の重量を人体の重量に近づけるべく、気体栓の筒体から液体（水など）を風船内に注入して、風船の重量を増やすことが考えられる。しかしながら、風船に設けられる一般的な気体栓は、筒体の内径が６ｍｍ未満とされる。このため、市場に流通する液体供給管（例えば漏斗や水道栓に接続されるホース）の一般的なものを筒体に接続することができないため、風船の内部に液体を注入することが容易でない。 Therefore, in order to bring the weight of the balloon closer to the weight of the human body, it is conceivable to inject a liquid (water or the like) into the balloon from the cylinder of the gas plug to increase the weight of the balloon. However, in a general gas plug provided on a balloon, the inner diameter of the cylinder is less than 6 mm. For this reason, it is not easy to inject liquid into the balloon because it is not possible to connect a general liquid supply pipe (for example, a hose connected to a funnel or a tap) on the market to the cylinder. ..

本発明は、上記事項に鑑みなされたものであり、本発明の目的は、気体栓の筒体の内径が６ｍｍ未満とされる風船であって、液体を容易に注入可能な風船を提供することである。 The present invention has been made in view of the above matters, and an object of the present invention is to provide a balloon having an inner diameter of a cylinder of a gas plug of less than 6 mm and in which a liquid can be easily injected.

In the illustrated example, the upper end wall 8 has an oval shape, but the upper end wall 8 may have an elliptical shape or a circular shape, for example.

図３及び図４に示すように、気体栓２は、上記の第一筒体４と、台座１０と、栓体１１とを備える。これら気体栓２を構成する部材は、ポリエチレン、ポリプロピレン、ポリエステル、ポリアミド、塩化ビニル、ナイロン、エチレン−酢酸ビニル共重合樹脂等から形成される。 As shown in FIGS. 3 and 4, the gas plug 2 includes the first cylinder body 4, the pedestal 10, and the plug body 11. The members constituting these gas plugs 2 are formed of polyethylene, polypropylene, polyester, polyamide, vinyl chloride, nylon, ethylene-vinyl acetate copolymer resin and the like.

台座１０は、本体１２と、フランジ１３とを有する。本体１２は、上側になるほど外径が小さくなる円錐台状を呈する。フランジ１３は、本体１２の下端部から本体１２の径外側に突出するものであり、本体１２の周全体に延びる。腰部６の上端壁８には、気体を通過させるための開口１４（図３）が形成されており、この開口１４の外周縁にフランジ１３が接合されることで、開口１４は本体１２の内側に位置するものとされる。上記開口１４の外周縁へのフランジ１３の接合は、熱溶着、高周波溶着、超音波溶着、溶剤接着等によって実現される。 The pedestal 10 has a main body 12 and a flange 13. The main body 12 has a truncated cone shape in which the outer diameter becomes smaller toward the upper side. The flange 13 projects from the lower end of the main body 12 to the outside of the diameter of the main body 12 and extends over the entire circumference of the main body 12. An opening 14 (FIG. 3) for passing gas is formed in the upper end wall 8 of the waist portion 6, and the flange 13 is joined to the outer peripheral edge of the opening 14 so that the opening 14 is inside the main body 12. It is supposed to be located in. The bonding of the flange 13 to the outer peripheral edge of the opening 14 is realized by heat welding, high frequency welding, ultrasonic welding, solvent bonding and the like.

第一筒体４は、上端に開口４ａを有する有底の円筒体である。当該第一筒体４は、台座１０の上端１０ａを貫通するものであり、図４から明らかなように、第一筒体４の上側は台座１０の外側に位置し、第一筒体４の下側は台座１０の内側に位置する（台座１０の上端１０ａに第一筒体４の外周面が接合されることで、第一筒体４は台座１０と一体とされる）。第一筒体４の下側には、切り欠け１５（図４）が形成される。切り欠け１５（図４）は、第一筒体４の周の一部に延びるものであって、この切り欠け１５よりも下側の第一筒体４の範囲４ｂは、傾動可能な弁とされる。 The first cylinder 4 is a bottomed cylinder having an opening 4a at the upper end. The first cylinder 4 penetrates the upper end 10a of the pedestal 10, and as is clear from FIG. 4, the upper side of the first cylinder 4 is located outside the pedestal 10, and the first cylinder 4 The lower side is located inside the pedestal 10 (the first cylinder 4 is integrated with the pedestal 10 by joining the outer peripheral surface of the first cylinder 4 to the upper end 10a of the pedestal 10). A notch 15 (FIG. 4) is formed on the lower side of the first tubular body 4. The notch 15 (FIG. 4) extends to a part of the circumference of the first cylinder 4, and the range 4b of the first cylinder 4 below the notch 15 is a tiltable valve. Will be done.

栓体１１は、可撓性を有する連結バンド１６と、連結バンド１６を介して第一筒体４の上端部に連結される板部１７と、板部１７の表面から突出する突出部１８とを有しており、突出部１８は第一筒体４の内部に挿脱自在とされる。なお図示例では、突出部１８を第一筒体４の内部に円滑に挿入できるように、突出部１８が、一端に開口する筒体とされて縮径可能なものにされているともに、突出部１８の外周面が、突出部１８の先端に近づくほど、外径が小さくなるテーパー状とされているが、突出部１８は中実の柱体とされてもよい。 The plug 11 includes a flexible connecting band 16, a plate portion 17 connected to the upper end portion of the first tubular body 4 via the connecting band 16, and a protruding portion 18 projecting from the surface of the plate portion 17. The protruding portion 18 is removable inside the first tubular body 4. In the illustrated example, the protruding portion 18 is made into a tubular body that opens at one end so that the protruding portion 18 can be smoothly inserted into the inside of the first tubular body 4, and the diameter of the protruding portion 18 can be reduced. The outer peripheral surface of the portion 18 is tapered so that the outer diameter becomes smaller as it approaches the tip of the protruding portion 18, but the protruding portion 18 may be a solid pillar.

風船１の内部に気体（例えば空気）を注入する際には、図３（Ａ）に示すように、栓体１１の突出部１８を第一筒体４から抜き出すことで、第一筒体４が開封された状態とされる（すなわち第一筒体４の開口４ａが塞がれていない状態とされる）。そして例えばユーザが第一筒体４を口にくわえて第一筒体４の内部に空気を吹き込むことで、空気が第一筒体４の内部及び切り欠け１５（図４）を介して風船１の内部に注入される。これにより風船１が空気で膨らんだ状態となる。なお、第一筒体４の内部に気体供給管（図示せず）を挿入してもよい。この場合、気体供給管に気体を供給して、気体供給管の先端から気体を第一筒体４の内部に流出させることで、気体風船１の内部に気体が注入されて、風船１が空気で膨らんだ状態となる。なお風船１内に気体を注入する際には、図４（Ｂ）に示すように気体の圧力で第一筒体４の下端部４ｂが動して切り欠け１５の幅が広がることで、円滑に風船１内に気体を注入できる。 When injecting gas (for example, air) into the balloon 1, as shown in FIG. 3A, the protruding portion 18 of the plug 11 is pulled out from the first cylinder 4, so that the first cylinder 4 Is opened (that is, the opening 4a of the first cylinder 4 is not closed). Then, for example, when the user holds the first cylinder 4 in his mouth and blows air into the inside of the first cylinder 4, the air is blown into the inside of the first cylinder 4 and the balloon 1 through the notch 15 (FIG. 4). It is injected inside the. As a result, the balloon 1 is inflated with air. A gas supply pipe (not shown) may be inserted inside the first cylinder 4. In this case, by supplying gas to the gas supply pipe and letting the gas flow out from the tip of the gas supply pipe into the inside of the first cylinder 4, the gas is injected into the gas balloon 1 and the balloon 1 is air. It becomes inflated with. When injecting gas into the balloon 1, as shown in FIG. 4 (B), the lower end portion 4b of the first cylinder 4 moves due to the pressure of the gas to widen the width of the notch 15, which is smooth. Gas can be injected into the balloon 1.

そして風船１内への気体の注入を完了した後では、栓体１１の突出部１８を第一筒体４の内部に挿入することで（図３（Ｂ），図４（Ａ））、第一筒体４が密封された状態とされる（すなわち第一筒体４の開口４ａが塞がれた状態とされる）。これにより、風船１内の空気が第一筒体４から漏れることが防止されて、風船１が膨らんだ状態が維持される。なお風船１内への気体の注入を停止することに伴い、第一筒体４の範囲４ｂ（弁）が弾性復帰して切り欠け１５の幅が狭まることで、栓体１１の突出部１８を第一筒体４の内部に挿入するまでの間に風船１内の気体が漏れることが防止される。 Then, after the injection of the gas into the balloon 1 is completed, the protruding portion 18 of the plug 11 is inserted into the first cylinder 4 (FIGS. 3 (B) and 4 (A)). The single cylinder 4 is sealed (that is, the opening 4a of the first cylinder 4 is closed). As a result, the air in the balloon 1 is prevented from leaking from the first cylinder body 4, and the inflated state of the balloon 1 is maintained. As the injection of gas into the balloon 1 is stopped, the range 4b (valve) of the first cylinder 4 is elastically restored and the width of the notch 15 is narrowed, so that the protruding portion 18 of the plug 11 is formed. The gas in the balloon 1 is prevented from leaking until it is inserted into the first cylinder 4.

風船１内の空気を排出する際には、図３（Ｃ）や図４（Ｂ）に示すように、栓体１１の突出部１８を第一筒体４から抜き出すことで、第一筒体４が開封された状態とされる（すなわち第一筒体４の開口４ａが塞がれていない状態とされる）。そして例えばユーザが指Ｙで気体栓２を圧迫することで、第一筒体４の下端部４ｂを傾動させて、切り欠け１５の幅が広がった状態とされる。そしてこの状態で、例えばユーザが風船１を押し潰すことで、風船１内の空気が、切り欠け１５及び第一筒体４の内部を通過して、第一筒体４の開口４ａから排出される（図３（ｃ）の矢印は、第一筒体４の開口４ａから排出される空気の流れを示している）。 When the air in the balloon 1 is discharged, as shown in FIGS. 3 (C) and 4 (B), the protruding portion 18 of the plug 11 is pulled out from the first cylinder 4, so that the first cylinder is discharged. 4 is in an opened state (that is, the opening 4a of the first cylinder 4 is not closed). Then, for example, when the user presses the gas plug 2 with the finger Y, the lower end portion 4b of the first tubular body 4 is tilted, and the width of the notch 15 is widened. Then, in this state, for example, when the user crushes the balloon 1, the air in the balloon 1 passes through the notch 15 and the inside of the first cylinder 4, and is discharged from the opening 4a of the first cylinder 4. (The arrow in FIG. 3C indicates the flow of air discharged from the opening 4a of the first cylinder 4).

図５〜図７に示すように、液体栓３は、上記の第二筒体５と、内蓋２０と、外蓋２１とを備える（図５は、液体栓３から内蓋２０や外蓋２１を取り外した状態を示している）。これら液体栓３を構成する部材は、ポリエチレン、ポリプロピレン、ポリエステル、ポリアミド、塩化ビニル、ナイロン、エチレン−酢酸ビニル共重合樹脂等から形成される。 As shown in FIGS. 5 to 7, the liquid plug 3 includes the second cylinder body 5, the inner lid 20, and the outer lid 21 (FIG. 5 shows the liquid plug 3 to the inner lid 20 and the outer lid). 21 is shown in a removed state). The members constituting these liquid stoppers 3 are formed of polyethylene, polypropylene, polyester, polyamide, vinyl chloride, nylon, ethylene-vinyl acetate copolymer resin and the like.

第二筒体５は、上端及び下端に開口を有する円筒体である。第二筒体５は、上端が腰部６（図１）の外側に位置し、下端が腰部６の内側に位置するように、腰部６の上端壁８に接合される。当該上端壁８への第二筒体５の接合は、熱溶着、高周波溶着、超音波溶着、溶剤接着等によって実現される。また、上端壁８から上側に延び出た第二筒体５の範囲では、第二筒体５の外周面に螺旋溝５ａ（図６，図７）が形成される。 The second cylinder 5 is a cylinder having openings at the upper and lower ends. The second tubular body 5 is joined to the upper end wall 8 of the lumbar portion 6 so that the upper end is located outside the lumbar portion 6 (FIG. 1) and the lower end is located inside the lumbar portion 6. The joining of the second cylinder 5 to the upper end wall 8 is realized by heat welding, high frequency welding, ultrasonic welding, solvent bonding and the like. Further, in the range of the second tubular body 5 extending upward from the upper end wall 8, a spiral groove 5a (FIGS. 6 and 7) is formed on the outer peripheral surface of the second tubular body 5.

図６（Ａ），図７（Ｃ）に示すように、内蓋２０は、円柱状の本体２２と、本体２２の一端に設けられるフランジ２３とを備える。フランジ２３は、本体２２の径外側へ突出するものであり、本体２２の周全体に延びる。 As shown in FIGS. 6A and 7C, the inner lid 20 includes a columnar main body 22 and a flange 23 provided at one end of the main body 22. The flange 23 projects outward from the diameter of the main body 22 and extends over the entire circumference of the main body 22.

図６（Ｂ），図７（Ｂ）に示すように、外蓋２１は、一端側に開口を有する有底の円筒体である。外蓋２１の内周面には螺旋溝２１ａが形成される。 As shown in FIGS. 6 (B) and 7 (B), the outer lid 21 is a bottomed cylindrical body having an opening on one end side. A spiral groove 21a is formed on the inner peripheral surface of the outer lid 21.

上記の液体栓３は、内蓋２０のフランジ２３が第二筒体５の上端に当接するまで、内蓋２０の本体２２を第二筒体５の内部に挿入することで、第二筒体５を内蓋２０で密封可能である（図６（Ａ），図６（Ｂ））。さらに液体栓３は、図６（Ｂ）に示すように第二筒体５が内蓋２０で密閉された状態で、図６（Ｃ）に示すように外蓋２１を第二筒体５の外側に被せて、外蓋２１の螺旋溝２１ａと第二筒体５の螺旋溝５ａとを嵌合させることで、外蓋２１によって内蓋２０を固定し、且つ、外蓋２１及び内蓋２０によって第二筒体５を二重に密封することが可能である。 The liquid stopper 3 has a second cylinder body by inserting the main body 22 of the inner lid 20 into the second cylinder body 5 until the flange 23 of the inner lid 20 abuts on the upper end of the second cylinder body 5. 5 can be sealed with the inner lid 20 (FIGS. 6 (A) and 6 (B)). Further, in the liquid stopper 3, the outer lid 21 is attached to the second cylinder 5 as shown in FIG. 6 (C) with the second cylinder 5 sealed by the inner lid 20 as shown in FIG. 6 (B). By covering the outer side and fitting the spiral groove 21a of the outer lid 21 and the spiral groove 5a of the second tubular body 5, the inner lid 20 is fixed by the outer lid 21, and the outer lid 21 and the inner lid 20 are fixed. It is possible to double-seal the second cylinder 5 by the method.

また本実施形態の風船１では、腰部６の上端壁８に形成された凹部３０に液体栓３の全体が収容されることで、液体栓３が凹部３０から突出しないようになっている。凹部３０は、第二筒体５を支持する底板３１と、底板３１の外周全体から上側及び外側に延びる側板３２と、側板３２の上端の外周全体から外側に突出するフランジ３３とを備えており、腰部６の上端壁８を構成するシートＳ１にフランジ３３が接合されている。 Further, in the balloon 1 of the present embodiment, the entire liquid plug 3 is housed in the recess 30 formed in the upper end wall 8 of the waist portion 6, so that the liquid plug 3 does not protrude from the recess 30. The recess 30 includes a bottom plate 31 that supports the second tubular body 5, a side plate 32 that extends upward and outward from the entire outer circumference of the bottom plate 31, and a flange 33 that projects outward from the entire outer circumference of the upper end of the side plate 32. , The flange 33 is joined to the sheet S1 forming the upper end wall 8 of the waist portion 6.

風船１の内部に液体Ｌを注入する際には、第二筒体５に対して外蓋２１を相対的に回転させることで、外蓋２１の螺旋溝２１ａと第二筒体５の螺旋溝５ａとの嵌合を解除して、外蓋２１を第二筒５から取り外した後（図７（Ａ），図７（Ｂ））、内蓋２０を第二筒体５から引き抜くことで（図７（Ｃ））、第二筒体５が開封された状態とされる（すなわち、第二筒体５の上端の開口５ｂが塞がれていない状態とされる）。 When the liquid L is injected into the balloon 1, the outer lid 21 is rotated relative to the second cylinder 5, so that the spiral groove 21a of the outer lid 21 and the spiral groove of the second cylinder 5 are formed. After releasing the fitting with 5a and removing the outer lid 21 from the second cylinder 5 (FIGS. 7 (A) and 7 (B)), the inner lid 20 is pulled out from the second cylinder 5 ( FIG. 7C) shows that the second cylinder 5 is in an opened state (that is, the opening 5b at the upper end of the second cylinder 5 is not closed).

そして第二筒体５の開口５ｂから第二筒体５の内部に液体供給管（図示せず）を挿入する作業を行なうことで、当該液体供給管が第二筒体５に接続された状態とされる。そして当該液体供給管に液体Ｌを供給して、液体供給管の先端から液体Ｌを第二筒体５の内部に流出させることで、第二筒体５を介して風船１の内部に液体Ｌが注入される。 Then, by inserting a liquid supply pipe (not shown) into the inside of the second cylinder 5 from the opening 5b of the second cylinder 5, the liquid supply pipe is connected to the second cylinder 5. It is said that. Then, the liquid L is supplied to the liquid supply pipe, and the liquid L is discharged from the tip of the liquid supply pipe into the inside of the second cylinder 5, so that the liquid L enters the inside of the balloon 1 through the second cylinder 5. Is injected.

ここで上記の作業を行なう際には、第二筒体５の内径Ｂが２０ｍｍ以上であるため、市場に多く流通する一般的な液体供給管を第二筒体５に接続できる。上記の「液体供給管」は、例えば、大径の容器から小径の管へと液体Ｌを流すことの可能な漏斗、水道栓に接続されるホース、或いは水道栓自身である。この種の液体供給管（漏斗やホースや水道栓）には、内径Ｂが２０ｍｍ以上である第二筒体５に接続可能なものが多く存在する。 Here, when performing the above operation, since the inner diameter B of the second cylinder 5 is 20 mm or more, a general liquid supply pipe widely distributed in the market can be connected to the second cylinder 5. The above-mentioned "liquid supply pipe" is, for example, a funnel capable of flowing a liquid L from a large-diameter container to a small-diameter pipe, a hose connected to a water tap, or the tap itself. Many of these types of liquid supply pipes (funnels, hoses, water taps) can be connected to the second cylinder 5 having an inner diameter B of 20 mm or more.

風船１内に液体Ｌを注入した後では、内蓋２０のフランジ３３が第二筒体５の上端に当接するまで、内蓋２０の本体２２を第二筒体５の内部に挿入することが行なわれる（図６（Ａ），図６（Ｂ））。そしてこの後、外蓋２１を第二筒体５の外側に被せて、第二筒体５に対して外蓋２１を相対的に回転させることで、外蓋２１の螺旋溝２１ａと第二筒体５の螺旋溝５ａとを嵌合させることが行なわれる（図６（Ｃ））。これにより、内蓋２０及び外蓋２１によって第二筒体５が二重に密封されるので、風船１の内部の液体Ｌが第二筒体５から漏れることを確実に防止できる。 After injecting the liquid L into the balloon 1, the main body 22 of the inner lid 20 may be inserted into the second cylinder 5 until the flange 33 of the inner lid 20 comes into contact with the upper end of the second cylinder 5. This is done (FIG. 6 (A), FIG. 6 (B)). After that, the outer lid 21 is put on the outside of the second cylinder body 5 and the outer lid 21 is rotated relative to the second cylinder body 5, so that the spiral groove 21a and the second cylinder of the outer lid 21 are formed. Fitting with the spiral groove 5a of the body 5 is performed (FIG. 6 (C)). As a result, the second cylinder 5 is doubly sealed by the inner lid 20 and the outer lid 21, so that the liquid L inside the balloon 1 can be reliably prevented from leaking from the second cylinder 5.

風船１の内部の液体Ｌを排出する際には、外蓋２１の螺旋溝２１ａと第二筒体５の螺旋溝５ａとの嵌合を解除して、第二筒から外蓋２１を取り外すことが行なわれる（図７（Ａ），図７（Ｂ））。そしてこの後、第二筒体５から内蓋２０を引き抜くことで（図７（Ｃ））、第二筒体５が開封された状態とされる（すなわち第二筒体５の開口５ｂが塞がれていない状態とされる）。そして風船１を逆さまにすることで（つまり、第二筒体５が下側に位置するように、風船１の向きを変えることで）、風船１の内部にある液体Ｌを第二筒体５の開口５ｂから排出させることが行なわれる。 When discharging the liquid L inside the balloon 1, the spiral groove 21a of the outer lid 21 and the spiral groove 5a of the second cylinder 5 are disengaged, and the outer lid 21 is removed from the second cylinder. (Fig. 7 (A), Fig. 7 (B)). After that, by pulling out the inner lid 20 from the second cylinder 5 (FIG. 7 (C)), the second cylinder 5 is in an opened state (that is, the opening 5b of the second cylinder 5 is closed. It is said that it is not peeled off). Then, by turning the balloon 1 upside down (that is, by changing the direction of the balloon 1 so that the second cylinder 5 is located on the lower side), the liquid L inside the balloon 1 is changed to the second cylinder 5. It is discharged from the opening 5b of.

オムツ交換のトレーニングに風船１が使用される際には、まず、液体栓３の第二筒体５から液体Ｌを風船１の内部に注入して風船１の重量を増やすことが行なわれる。この後、気体栓２の第一筒体４から風船１の内部に気体（例えば空気）を注入することで、風船１が膨らんだ状態とされる。そして上述のように液体Ｌで風船１の重量が増え、且つ、風船１が気体で膨らんだ状態で、オムツを風船１に取り付ける作業や、風船１からオムツを取り外す作業が行なわれる。 When the balloon 1 is used for training for changing diapers, first, the liquid L is injected into the inside of the balloon 1 from the second cylinder 5 of the liquid stopper 3 to increase the weight of the balloon 1. After that, a gas (for example, air) is injected into the balloon 1 from the first cylinder 4 of the gas plug 2, so that the balloon 1 is inflated. Then, as described above, the weight of the balloon 1 is increased by the liquid L, and the diaper is attached to the balloon 1 and the diaper is removed from the balloon 1 in a state where the balloon 1 is inflated with gas.

本実施形態の風船１によれば、第二筒体５の内径Ｂが２０ｍｍ以上であるため、市場に多く流通する一般的な液体供給管を、第二筒体５に接続できる。したがって本実施形態の風船１によれば、その内部に液体Ｌを注入することが容易である。そしてこのことから、本実施形態の風船１は、液体Ｌによって重量を増やすことができるので、風船１を、少しの力で向きが変わらないものにすることができる。したがって風船１を用いるオムツ交換のトレーニングを、実際のオムツ交換（人体に施すオムツ交換）に近しいものにすることができる（つまり、風船１を用いるオムツ交換のトレーニングを、実際のオムツ交換と同等の困難さを持つものにすることができる）。 According to the balloon 1 of the present embodiment, since the inner diameter B of the second cylinder 5 is 20 mm or more, a general liquid supply pipe widely distributed in the market can be connected to the second cylinder 5. Therefore, according to the balloon 1 of the present embodiment, it is easy to inject the liquid L into the balloon 1. From this, since the weight of the balloon 1 of the present embodiment can be increased by the liquid L, the balloon 1 can be made to have the same orientation with a little force. Therefore, the training for changing diapers using balloon 1 can be made close to the actual changing of diapers (changing diapers applied to the human body) (that is, the training for changing diapers using balloon 1 is equivalent to the actual changing of diapers. Can be difficult).

本発明の風船は、上述した実施形態に示すものに限定されず、種々改変できる。 The balloon of the present invention is not limited to the one shown in the above-described embodiment, and can be variously modified.

例えば上記の実施形態では、腰部６の上端壁８に気体栓２が設けられていたが、上端壁８以外の腰部６の壁に気体栓２を設けてもよく、また腰部６以外の風船１の壁に気体栓２を設けてもよい。上記の場合には、上端壁８以外の風船１の壁に気体通過用の開口１４（図３，図４）が形成されて、この開口１４の外周縁に気体栓２のフランジ１３が接合されることで、開口１４が気体栓２の本体１２の内側に位置するものとされる。 For example, in the above embodiment, the gas plug 2 is provided on the upper end wall 8 of the lumbar portion 6, but the gas plug 2 may be provided on the wall of the lumbar portion 6 other than the upper end wall 8, and the balloon 1 other than the lumbar portion 6 may be provided. A gas plug 2 may be provided on the wall of the wall. In the above case, an opening 14 (FIGS. 3 and 4) for passing gas is formed in the wall of the balloon 1 other than the upper end wall 8, and the flange 13 of the gas plug 2 is joined to the outer peripheral edge of the opening 14. As a result, the opening 14 is located inside the main body 12 of the gas plug 2.

また本発明の風船に設けられる気体栓は、上記の気体栓２に限定されない。本発明の風船には、内径が６ｍｍ未満である筒体を有する公知の気体栓を設けることができる。 Further, the gas plug provided in the balloon of the present invention is not limited to the gas plug 2 described above. The balloon of the present invention may be provided with a known gas plug having a tubular body having an inner diameter of less than 6 mm.

また上記の実施形態では、腰部６の上端壁８に液体栓３が設けられていたが、上端壁８以外の腰部６の壁に液体栓３が設けられてもよく、また腰部６以外の風船１の壁に液体栓３が設けられてもよい。上記の場合には、液体栓３の第二筒体５（図５〜図７）は、上側が風船１の外側に位置し、且つ、下側が風船１の内側に位置するように、風船１の壁に接合される。 Further, in the above embodiment, the liquid stopper 3 is provided on the upper end wall 8 of the waist portion 6, but the liquid stopper 3 may be provided on the wall of the waist portion 6 other than the upper end wall 8, and the balloon other than the waist portion 6 A liquid stopper 3 may be provided on the wall of 1. In the above case, the second cylinder 5 (FIGS. 5 to 7) of the liquid stopper 3 has the balloon 1 so that the upper side is located outside the balloon 1 and the lower side is located inside the balloon 1. Joined to the wall of.

また上述のように上端壁８以外の風船１の壁に液体栓３が設けられる場合でも、風船１の壁に凹部を形成して、この凹部に液体栓３の全体を収容してもよい。この場合、例えば、凹部は、第二筒体５を支持する底板と、当該底板の外周全体から上側及び外側に傾斜して延びる側板と、側板の上端の外周全体から外側に突出するフランジとを備えるものとされて、風船１を構成するシートＳにフランジが接合される。 Further, even when the liquid stopper 3 is provided on the wall of the balloon 1 other than the upper end wall 8 as described above, a recess may be formed in the wall of the balloon 1 and the entire liquid stopper 3 may be accommodated in the recess. In this case, for example, the recess includes a bottom plate that supports the second cylinder 5, a side plate that extends upward and outward from the entire outer circumference of the bottom plate, and a flange that projects outward from the entire outer circumference of the upper end of the side plate. A flange is joined to the sheet S constituting the balloon 1.

また内蓋２０は、必ずしも必要ではなく、液体栓３から省略されてもよい。この場合、外蓋２１を第二筒体５の外側に被せて、外蓋２１の螺旋溝２１ａと第二筒体５の螺旋溝５ａとを嵌合させることで、外蓋２１によって第二筒体５を密封可能とされる。また、外蓋２１の螺旋溝２１ａと第二筒体５の螺旋溝５ａとの嵌合を解除し、第二筒体５から外蓋２１を取り外すことで、第二筒体５を開封可能とされる。 Further, the inner lid 20 is not always necessary and may be omitted from the liquid stopper 3. In this case, the outer lid 21 is put on the outside of the second cylinder 5, and the spiral groove 21a of the outer lid 21 and the spiral groove 5a of the second cylinder 5 are fitted, so that the second cylinder is formed by the outer lid 21. The body 5 can be sealed. Further, the second cylinder 5 can be opened by releasing the fitting between the spiral groove 21a of the outer lid 21 and the spiral groove 5a of the second cylinder 5 and removing the outer lid 21 from the second cylinder 5. Will be done.

また図５〜図７に示す液体栓３の代わりに、図８及び図９に示す液体栓４０が風船１に設けられてもよい。以下、図８及び図９に示す液体栓４０について説明する。 Further, instead of the liquid stopper 3 shown in FIGS. 5 to 7, the liquid stopper 40 shown in FIGS. 8 and 9 may be provided on the balloon 1. Hereinafter, the liquid stopper 40 shown in FIGS. 8 and 9 will be described.

液体栓４０は、腰部６の平坦な上端壁８に設けられるものであって、第二筒体４１と、フランジ４２と、栓体４３とを有する。これら液体栓４０を構成する部材は、ポリエチレン、ポリプロピレン、ポリエステル、ポリアミド、塩化ビニル、ナイロン、エチレン−酢酸ビニル共重合樹脂等から形成される。 The liquid plug 40 is provided on the flat upper end wall 8 of the waist portion 6, and has a second tubular body 41, a flange 42, and a plug body 43. The members constituting these liquid stoppers 40 are formed of polyethylene, polypropylene, polyester, polyamide, vinyl chloride, nylon, ethylene-vinyl acetate copolymer resin and the like.

第二筒体４１は、上端に開口を有する有底の円筒体であり、内径Ｃが２０ｍｍ以上とされる。第二筒体４１の下端部では、第二筒体４１の周の一部に延びる切り欠け４４が形成されており、切り欠け４４よりも内側の範囲４１ａが、液体Ｌの圧力で傾動可能な弁とされている。図示例では、第二筒体４１の下端面をなす円板に、その周方向に延びる円弧状の切り欠け４４を形成することで（当該円弧状の切り欠け４４は、第二筒体４１の内周面の延長線に沿って形成されたものである）、切り欠け４４よりも内側の範囲４１ａが上記の弁とされている。なお第二筒体４１の下端部をなす周壁に、第二筒体４１の周の一部に延びる切り欠けを形成することで、切り欠けよりも下側の範囲（すなわち切り欠けよりも下側に位置する周壁の範囲及び上記円板）を、液体Ｌの圧力で傾動可能な弁としてもよい。 The second cylinder 41 is a bottomed cylinder having an opening at the upper end, and has an inner diameter C of 20 mm or more. At the lower end of the second cylinder 41, a notch 44 extending to a part of the circumference of the second cylinder 41 is formed, and a range 41a inside the notch 44 can be tilted by the pressure of the liquid L. It is said to be a valve. In the illustrated example, an arc-shaped notch 44 extending in the circumferential direction is formed on the disk forming the lower end surface of the second cylinder 41 (the arc-shaped notch 44 is the second cylinder 41. The valve is formed in a range 41a inside the notch 44 (which is formed along an extension line of the inner peripheral surface). By forming a notch extending to a part of the circumference of the second cylinder 41 on the peripheral wall forming the lower end of the second cylinder 41, the range below the notch (that is, the lower side than the notch). The range of the peripheral wall located at and the disk) may be a valve that can be tilted by the pressure of the liquid L.

フランジ４２は、第二筒体４１の周壁から第二筒体４１の径外側に突出するものであり、第二筒体４１の周全体に延びる。 The flange 42 projects from the peripheral wall of the second cylinder 41 to the outside of the diameter of the second cylinder 41, and extends over the entire circumference of the second cylinder 41.

栓体４３は、可撓性を有する連結バンド４５と、連結バンド４５を介してフランジ４２に連結される板部４６と、板部４６の表面から突出する突出部４７とを有しており、突出部４７が第二筒体４１の内部に挿脱自在とされる。 The plug body 43 has a flexible connecting band 45, a plate portion 46 connected to the flange 42 via the connecting band 45, and a protruding portion 47 protruding from the surface of the plate portion 46. The protruding portion 47 is freely insertable and detachable inside the second tubular body 41.

上記の液体栓４０は、第二筒体４１の上側が腰部６の外側に位置し、第二筒体４１の下側が腰部６の内側に位置するように、第二筒体４１が腰部６の上端壁８を貫通するものとされて、フランジ４２が腰部６の上端壁８に接合される。当該フランジ４２の接合は、熱溶着、高周波溶着、超音波溶着、溶剤接着等によって実現される。 In the above liquid plug 40, the second cylinder 41 is located on the waist 6 so that the upper side of the second cylinder 41 is located on the outside of the lumbar portion 6 and the lower side of the second cylinder 41 is located on the inside of the lumbar portion 6. The flange 42 is joined to the upper end wall 8 of the lumbar portion 6 so as to penetrate the upper end wall 8. The joining of the flange 42 is realized by heat welding, high frequency welding, ultrasonic welding, solvent bonding and the like.

風船１の内部に液体Ｌを注入する際には、図８（Ａ）や図９（Ａ）に示すように栓体４３の突出部４７を第二筒体４１から抜き出すことで、第二筒体４１が開封された状態とされる。そしてこの状態で、第二筒体４１の内部に液体供給管Ｋ（図９（Ａ））を挿入する作業を行なうことで、液体供給管Ｋが第二筒体４１に接続された状態とされる。そして液体供給管Ｋに液体Ｌを供給して、液体供給管Ｋの先端から液体Ｌを第二筒体４１の内部に流入させることが行なわれる。これにより、液体Ｌが、第二筒体４１の内部及び切り欠け４４を介して、風船１の内部に注入される。なおこの際には、液体Ｌの圧力で第二筒体４１の範囲４１ａ（弁）が傾動して切り欠け４４の幅が広がることで、風船１の内部に液体Ｌを円滑に注入できる。 When the liquid L is injected into the balloon 1, the protruding portion 47 of the plug body 43 is pulled out from the second cylinder body 41 as shown in FIGS. 8 (A) and 9 (A), so that the second cylinder The body 41 is considered to be in an opened state. Then, in this state, the liquid supply pipe K (FIG. 9A) is inserted into the second cylinder 41, so that the liquid supply pipe K is connected to the second cylinder 41. To. Then, the liquid L is supplied to the liquid supply pipe K, and the liquid L is allowed to flow into the inside of the second cylinder 41 from the tip of the liquid supply pipe K. As a result, the liquid L is injected into the inside of the balloon 1 through the inside of the second cylinder 41 and the notch 44. At this time, the pressure of the liquid L causes the range 41a (valve) of the second cylinder 41 to tilt and widen the width of the notch 44, so that the liquid L can be smoothly injected into the balloon 1.

そして風船１の内部に液体Ｌを注入した後では、図８（Ｂ）や図９（Ｂ）に示すように栓体４３の突出部４７を第二筒体４１の内部に挿入することで、第二筒体４１が密封された状態とされる。これにより、風船１内の液体Ｌが第二筒体４１から漏れることが防止される。なお風船１内への液体Ｌの注入を停止することに伴い、第二筒体４１の範囲４１ａ（弁）が弾性復帰して切り欠け４４の幅が狭まることで、栓体４３の突出部４７を第二筒体４１の内部に挿入するまでの間に、風船１内の液体Ｌが漏れることが防止される。 After injecting the liquid L into the balloon 1, the protruding portion 47 of the plug 43 is inserted into the second cylinder 41 as shown in FIGS. 8 (B) and 9 (B). The second cylinder 41 is in a sealed state. As a result, the liquid L in the balloon 1 is prevented from leaking from the second cylinder 41. As the injection of the liquid L into the balloon 1 is stopped, the range 41a (valve) of the second cylinder 41 elastically returns and the width of the notch 44 narrows, so that the protruding portion 47 of the plug body 43 The liquid L in the balloon 1 is prevented from leaking until the balloon 1 is inserted into the second cylinder 41.

風船１の内部の液体Ｌを排出する際には、第二筒体４１から栓体４３を引き抜くことで、第二筒体４１の上端の開口が露出した状態（第二筒体４１が開封された状態）とされる。そして第二筒体４１の内部に棒等を挿入して範囲４１ａ（弁）を押圧することで、範囲４１ａ（弁）を傾動させて、切り欠け４４の幅を広げることが行なわれる。そしてこの状態で風船１を逆さまにすることで（すなわち、第二筒体４１が下側に位置するように、風船１の向きを変えることで）、風船１の内部にある液体Ｌを、切り欠け４４を介して第二筒体４１の内部に流入させて、第二筒体４１の開口から排出させることが行なわれる。 When the liquid L inside the balloon 1 is discharged, the stopper 43 is pulled out from the second cylinder 41 so that the opening at the upper end of the second cylinder 41 is exposed (the second cylinder 41 is opened. State). Then, by inserting a rod or the like into the inside of the second cylinder 41 and pressing the range 41a (valve), the range 41a (valve) is tilted and the width of the notch 44 is widened. Then, by turning the balloon 1 upside down in this state (that is, by changing the direction of the balloon 1 so that the second cylinder 41 is located on the lower side), the liquid L inside the balloon 1 is cut off. It is made to flow into the inside of the second cylinder 41 through the chip 44 and to be discharged from the opening of the second cylinder 41.

上記の液体栓４０が風船１に設けられる場合でも、第二筒体４１の内径が２０ｍｍ以上とされることで、市場に多く流通する一般的な液体供給管を第二筒体４１に接続することができる。したがって風船１の内部に液体Ｌを注入することが容易である。 Even when the above liquid stopper 40 is provided on the balloon 1, the inner diameter of the second cylinder 41 is 20 mm or more, so that a general liquid supply pipe widely distributed in the market is connected to the second cylinder 41. be able to. Therefore, it is easy to inject the liquid L into the balloon 1.

May be provided with a liquid stopper 40. In this case, the second cylinder 41 penetrates the wall of the balloon 1 so that the upper side of the second cylinder 41 is located outside the balloon 1 and the lower side of the second cylinder 41 is located inside the balloon 1. The flange 42 is joined to the wall of the balloon 1.

また風船１の壁に形成された凹部に、液体栓４０の全体が収容されてもよい。この場合、例えば、凹部は、液体栓４０のフランジ４２を支持する底板と、当該底板の外周全体から上側且つ外側に傾斜して延びる側板と、側板の上端の外周全体から延びるフランジとを備えるものとされて、当該フランジが風船１を構成するシートＳに接合される。 Further, the entire liquid stopper 40 may be housed in the recess formed in the wall of the balloon 1. In this case, for example, the recess includes a bottom plate that supports the flange 42 of the liquid stopper 40, a side plate that extends upward and outwardly from the entire outer circumference of the bottom plate, and a flange that extends from the entire outer circumference of the upper end of the side plate. The flange is joined to the sheet S constituting the balloon 1.
