Description

本発明は、内部からの空気噴射によって空中を飛行するゴム風船を膨らませる際に使用するゴム風船用吹込み口部材に関する。 The present invention relates to a blow-in member for a rubber balloon used when inflating a rubber balloon flying in the air by air injection from the inside.

近年、プロ野球の球場観戦において一斉にゴム風船を上空へ飛ばして応援することが流行している。このゴム風船は、先端側がやや膨らんだ棒状のゴム風船本体と、このゴム風船本体の口部に取り付けられる合成樹脂からなる吹き口部材とから構成されている。かかるゴム風船は、吹き口部材から空気を吹き込んで膨らませてから手放すと、内部からの空気噴射を推進力として飛翔するとともに、吹き口部材が笛になって通過する空気によってピーという音を発する。 In recent years, it has become popular to support by blowing rubber balloons all together in a professional baseball game. This rubber balloon is composed of a stick-shaped rubber balloon body whose tip side is slightly inflated, and a blowing member made of a synthetic resin attached to the mouth of the rubber balloon body. When such rubber balloons are blown out after blowing air from the blowing member, the air balloons fly with the air jet from the inside as a driving force, and emit a beeping sound by the air passing through the blowing member as a whistle.

このゴム風船は、吹き口部材をくわえて空気を吹き込んで膨らませる、飛翔させるまでは空気が噴射しないように吹き口部材又はゴム風船本体の根元部を押さえておくことが必要となっている。
また、ゴム風船本体の収縮力による空気の戻りに抗して膨らませるのに大きな吹込み力が必要となるため、肺活量の小さい子どもや女性には膨らませることが難しい上に、膨らませてから保持している間になんらかの拍子に空気が抜けてしまったり、飛翔させる前に油断して手から離れて飛び去ってしまうという問題があった。
It is necessary to hold down the base part of the blowing member or the rubber balloon main body so that the balloon does not inject air until the balloon is blown up and inflated by adding the blowing member.
In addition, since a large blowing force is required to inflate against the return of air due to the contraction force of the rubber balloon body, it is difficult to inflate for children and women with small vital capacity, and hold after inflating While doing so, there was a problem that the air suddenly escaped, or I was not careful before flying and left away from my hand.

かかる問題を解消するために、特許第4904377号公報記載の『ゴム風船発射装置』が創案された。   In order to solve this problem, a “rubber balloon launcher” described in Japanese Patent No. 4904377 has been devised.

特許第4904377号公報Japanese Patent No. 4904377

しかしなから、上述の特許第4904377号公報記載の『ゴム風船発射装置』は、ゴム風船を肺活量の小さい子どもなどにも膨らませやすく、膨らませてからも空気が抜けないなどの一定の目的は達成しているが、衛生面での問題がある。
すなわち、ゴム風船を膨らませる際に、唾液がゴム風船に吹き込まれ、飛翔と同時に唾液が空気とともにまき散らされるという問題である。
近年の新型インフルエンザ等に代表される感染症は、ウィルスが含まれる唾液を介して感染することが知られており、これらの感染予防に対して上記『ゴム風船発射装置』のみならず、従来の飛翔するゴム風船はまったく対策が施されていなかった。飛翔するゴム風船からまき散らされる唾液が感染症の拡散の原因となったという事実は現時点では確認されていないようであるが、そのような感染症の拡散に対する予防的措置がまったく施されていないという点も事実である。
However, the “rubber balloon launcher” described in the above-mentioned Japanese Patent No. 4904377 is easy to inflate the rubber balloon to children with small lung capacity, and achieves a certain purpose such as the air does not escape after inflating. However, there are problems with hygiene.
That is, when the rubber balloon is inflated, saliva is blown into the rubber balloon, and the saliva is sprinkled with the air at the same time as the flight.
Infectious diseases typified by new influenza in recent years are known to infect through virus-containing saliva, and not only the above “rubber balloon launcher” but also conventional No measures were taken for the flying balloons. The fact that saliva sprinkled from flying balloons caused the spread of infection did not appear to be confirmed at this time, but no precautions have been taken against the spread of such infection. That is also true.

本発明は、上記事情に鑑みて創案されたもので、空気を吹き込む際に感染症の原因となりうる唾液がゴム風船に入らないようにしたゴム風船用吹込み口部材を提供することを目的としている。 The present invention was devised in view of the above circumstances, and an object thereof is to provide a blowing member for a rubber balloon that prevents saliva that may cause infections from entering the rubber balloon when air is blown. Yes.

本発明に係るゴム風船用吹込み口部材は、口部に取り付けられたノズル部材を介して内部から空気を噴射して空中を飛行するゴム風船に空気を吹き込むゴム風船用吹込み口部材であって、空気を吹き込む際にくわえる吹込み筒と、この吹込み筒に連結される受け筒と、吹込み筒と受け筒との間に介在されるフィルターとを備えており、前記吹込み筒は外周面に雄ねじが形成された大径部と、この大径部の先端部の内側に形成された段差とを有しており、前記受け筒は内部に雌ねじが形成されたカップ部と、このカップ部の内面に形成された円弧状の凸脈とを有しており、雄ねじと雌ねじとは吹込み筒と受け筒とを連結させるべく対応しており、吹込み筒と受け筒とが連結されると、大径部の先端部がカップ部の外周部と凸脈との間に嵌まり込んで、前記フィルターが受け筒の凸脈と吹込み筒の段差とで挟み込まれるようになっている。 The rubber balloon blowing port member according to the present invention is a rubber balloon blowing port member that blows air into a rubber balloon flying in the air by injecting air from the inside through a nozzle member attached to the mouth portion. A blowing cylinder that is inserted when air is blown, a receiving cylinder that is connected to the blowing cylinder, and a filter that is interposed between the blowing cylinder and the receiving cylinder. The outer peripheral surface has a large-diameter portion formed with a male screw and a step formed inside the tip portion of the large-diameter portion, and the receiving tube has a cup portion with a female screw formed therein, It has an arc-shaped convex vein formed on the inner surface of the cup part, and the male screw and the female screw correspond to connect the blowing cylinder and the receiving cylinder, and the blowing cylinder and the receiving cylinder are connected. The tip of the large diameter part fits between the outer periphery of the cup part and the convex vein. In the so that the filter is sandwiched between the convex pulse and the step of blowing tube of accommodation tub.

本発明に係るゴム風船用吹込み口部材は、内部にフィルターを有しているので、空気をゴム風船に吹き込む際、唾液がゴム風船に入り込むことがないので、ゴム風船を飛翔させても、または破裂させても感染症の原因となるウィルスをまき散らすおそれはない。 Since the blowing port member for the rubber balloon according to the present invention has a filter inside, when the air is blown into the rubber balloon, saliva does not enter the rubber balloon. Or, even if ruptured, there is no risk of spreading the virus that causes infection.

また、本発明に係るゴム風船用吹込み口部材は、逆止弁を設けているので、小径部から口を外してもゴム風船から空気が漏れだすおそれはない。 In addition, the rubber balloon blowing port member according to the present invention is provided with a check valve, so that air does not leak from the rubber balloon even if the mouth is removed from the small diameter portion.

本発明の実施の形態に係るゴム風船用吹込み口部材1000は、口部511に取り付けられたノズル部材520を介して内部から空気を噴射して空中を飛行するゴム風船500に空気を吹き込むゴム風船用吹込み口部材であって、空気を吹き込む際にくわえる吹込み筒200と、この吹込み筒200に連結される受け筒100と、吹込み筒200と受け筒100との間に介在されるフィルター400とを備えており、前記吹込み筒200は外周面に雄ねじ221が形成された大径部220と、この大径部220の先端部の内側に形成された段差224とを有しており、前記受け筒100は内部に雌ねじ121が形成されたカップ部120と、このカップ部120の内面に形成された円弧状の凸脈123とを有しており、雄ねじ221と雌ねじ121とは吹込み筒200と受け筒100とを連結させるべく対応しており、吹込み筒200と受け筒100とが連結されると、大径部220の先端部がカップ部120の外周部と凸脈123との間に嵌まり込んで、前記フィルター400が受け筒100の凸脈と吹込み筒200の段差224とで挟み込まれるようになっている。 A rubber balloon blowing port member 1000 according to an embodiment of the present invention is a rubber that blows air into a rubber balloon 500 that injects air from the inside through a nozzle member 520 attached to a mouth portion 511 and flies in the air. A balloon blowing port member, which is interposed between the blowing cylinder 200 and the receiving cylinder 100, and a blowing cylinder 200 connected to the blowing cylinder 200. The blow tube 200 has a large diameter portion 220 having an external thread 221 formed on the outer peripheral surface, and a step 224 formed inside the tip of the large diameter portion 220. The receiving tube 100 has a cup portion 120 in which a female screw 121 is formed, and an arc-shaped convex pulse 123 formed on the inner surface of the cup portion 120. The male screw 221 and the female screw 21 corresponds to connecting the blowing cylinder 200 and the receiving cylinder 100, and when the blowing cylinder 200 and the receiving cylinder 100 are connected, the tip of the large diameter portion 220 is the outer peripheral portion of the cup portion 120. The filter 400 is sandwiched between the convex pulse of the receiving cylinder 100 and the step 224 of the blowing cylinder 200.

本発明の実施の形態に係るゴム風船用吹込み口部材1000を使って膨らませられるゴム風船500は、図5に示すように、先端側がやや膨らんだ棒状のゴム風船本体510と、このゴム風船本体510の口部511に取り付けられる合成樹脂からなるノズル部材520とから構成されている。
前記ゴム風船本体510の口部511には、他の部分より厚めになった凸脈状部512が形成されている(図4参照)。
As shown in FIG. 5, a rubber balloon 500 that is inflated using the rubber balloon blowing port member 1000 according to the embodiment of the present invention includes a stick-shaped rubber balloon main body 510 having a slightly inflated tip side, and the rubber balloon main body. The nozzle member 520 is made of a synthetic resin attached to the mouth portion 511 of the 510.
The mouth portion 511 of the rubber balloon body 510 is formed with a convex vein portion 512 that is thicker than other portions (see FIG. 4).

また、前記ノズル部材520は、ゴム風船本体510の前記突脈状部512が嵌まり込む凹部521Aが形成された略円筒形状の第1ノズル部材521と、この第1ノズル部際521に外嵌される略円筒形状の第2ノズル部材522とを有している。第2ノズル部材522は、第1ノズル部材521に外嵌されると、第2ノズル部材522の外周部522Aの先端が前記凹部521Aをほぼ覆うようになっている。従って、ゴム風船本体510をこのノズル部材520に取り付けると、凸脈状部512が凹部521Aと外周部522Aとで覆われる結果、ゴム風船本体510がノズル部材520からより外れにくくなっている。
前記第2ノズル部材522の後端、すなわち第1ノズル部材521を外嵌する側とは反対側には、本発明の実施の形態に係るゴム風船用吹込み口部材1000の受け筒100の連結部110が連結されるノズル側連結部522Bが形成されている。
なお、このゴム風船本体510に取り付けられるノズル部材520は、通過する空気によって音を発する機能を有している。
In addition, the nozzle member 520 is externally fitted to the first nozzle member 521 having a substantially cylindrical shape in which a concave portion 521A into which the protruding portion 512 of the rubber balloon main body 510 is fitted, and the first nozzle portion 521. And a second nozzle member 522 having a substantially cylindrical shape. When the second nozzle member 522 is externally fitted to the first nozzle member 521, the tip of the outer peripheral portion 522A of the second nozzle member 522 substantially covers the recess 521A. Therefore, when the rubber balloon main body 510 is attached to the nozzle member 520, the convex vein-shaped portion 512 is covered with the concave portion 521A and the outer peripheral portion 522A, so that the rubber balloon main body 510 is more difficult to come off from the nozzle member 520.
The rear end of the second nozzle member 522, that is, the side opposite to the side on which the first nozzle member 521 is externally fitted, is connected to the receiving cylinder 100 of the rubber balloon blowing port member 1000 according to the embodiment of the present invention. A nozzle side connecting portion 522B to which the portion 110 is connected is formed.
The nozzle member 520 attached to the rubber balloon main body 510 has a function of generating sound by the passing air.

本発明の実施の形態に係るゴム風船用吹込み口部材1000を構成する受け筒100は、図2に示すように、小径の略円筒形状の連結部110と、この連結部110より径大の略円筒形状のカップ部120とが一体に形成されたものである。前記連結部110は、ゴム風船本体510に取り付けられるノズル部材520を構成する第2ノズル部材522のノズル側連結部522Bに挿入して連結される。この連結部110は、ノズル側連結部522Bへの挿入がスムーズになるように、外面は先細り状となるようにテーパ面となっている。 As shown in FIG. 2, the receiving tube 100 constituting the rubber balloon blowing port member 1000 according to the embodiment of the present invention has a small-diameter substantially cylindrical connecting portion 110 and a diameter larger than that of the connecting portion 110. The substantially cylindrical cup portion 120 is integrally formed. The connecting part 110 is inserted and connected to the nozzle side connecting part 522B of the second nozzle member 522 constituting the nozzle member 520 attached to the rubber balloon body 510. The connecting portion 110 has a tapered surface so that the outer surface is tapered so that insertion into the nozzle side connecting portion 522B is smooth.

また、前記カップ部120は、内部に雌ねじ121が形成されている。また、このカップ部120の段差部122の内面には、円弧状に凸脈123が突出形成されている。この凸脈123は、後述する吹込み筒200を連結した際に、吹込み筒200の段差224とでフィルター400を挟み込む部分となる。   The cup portion 120 has a female screw 121 formed therein. Further, on the inner surface of the stepped portion 122 of the cup portion 120, a convex pulse 123 is formed to project in an arc shape. The convex pulse 123 becomes a portion that sandwiches the filter 400 with the step 224 of the blowing cylinder 200 when the blowing cylinder 200 described later is connected.

一方、上述した受け筒100とともにゴム風船用吹込み口部材1000を構成する吹込み筒200は、図3に示すように、口でくわえる小径部210と、この小径部210より径大の大径部220と、この大径部220と前記小径部210とを繋ぐテーパー部230とが一体に形成されている。 On the other hand, as shown in FIG. 3, the blowing cylinder 200 that constitutes the rubber balloon blowing port member 1000 together with the receiving cylinder 100 described above has a small-diameter portion 210 that is included in the mouth, and a large diameter that is larger than the small-diameter portion 210. A portion 220 and a tapered portion 230 connecting the large diameter portion 220 and the small diameter portion 210 are integrally formed.

前記小径部210の終端には口にくわえた際に不用意に落下させないようにする微小フランジ部211が形成されている。
また、前記大径部220は、外周面に前記雌ねじ121に対応した雄ねじ221が形成されている。しかも、この大径部220の外周面のテーパ部230側には、前記受け筒100と連結された状態でテーパ部230と受け筒100のカップ部120とが面一になるように、カップ部120の厚さ寸法に相当する段差222が形成されている。さらに、この大径部220の先端部223は、内側に段差224が形成されることで他の部分より肉薄に形成されている。このように先端部223が肉薄に形成されるいるのは、前記受け筒100と連結した場合、受け筒100のカップ部120の外周部と凸脈123との間に嵌まり込むようにするためである
A small flange portion 211 is formed at the end of the small-diameter portion 210 so that the small-diameter portion 210 is not accidentally dropped when it is put in the mouth.
The large-diameter portion 220 is formed with a male screw 221 corresponding to the female screw 121 on the outer peripheral surface. In addition, on the tapered portion 230 side of the outer peripheral surface of the large-diameter portion 220, the cup portion so that the tapered portion 230 and the cup portion 120 of the receiving tube 100 are flush with each other when connected to the receiving tube 100. A step 222 corresponding to a thickness dimension of 120 is formed. Furthermore, the front-end | tip part 223 of this large diameter part 220 is formed thinner than another part by forming the level | step difference 224 inside. The tip 223 is thinly formed in this manner in order to fit between the outer peripheral portion of the cup 120 of the receiving tube 100 and the convex pulse 123 when connected to the receiving tube 100. It is .

前記テーパ部230には、小径部210の内径より大きくかつ大径部220の内径より小さい直径を有する逆止弁となる球体300がセットされている。   A spherical body 300 serving as a check valve having a diameter larger than the inner diameter of the small diameter portion 210 and smaller than the inner diameter of the large diameter portion 220 is set on the tapered portion 230.

前記フィルター400は、少なくとも唾液が通過しないようにするものであって、略円形に形成されている。かかるフィルター400は、受け筒100の凸脈123と、吹込み筒200の段差224とで挟み込まれてゴム風船用吹込み口部材1000の内部にセットされる。 The filter 400 prevents at least saliva from passing, and is formed in a substantially circular shape. The filter 400 is sandwiched between the convex pulse 123 of the receiving cylinder 100 and the step 224 of the blowing cylinder 200 and is set inside the rubber balloon blowing port member 1000 .

このように構成されたゴム風船用吹込み口部材1000は以下のようにして使用される。
まず、吹込み口部材1000の連結部110をゴム風船500のノズル側連結部522Bに挿入接続する。
この状態でゴム風船用吹込み口部材1000の小径部210をくわえて空気をゴム風船本体510に吹き込む。この際、空気が吹き込まれる勢いで逆止弁である球体300と小径部210との間には隙間が形成される。
The rubber balloon blowing port member 1000 configured as described above is used as follows.
First, the connecting portion 110 of the blowing port member 1000 is inserted and connected to the nozzle side connecting portion 522B of the rubber balloon 500.
In this state, air is blown into the rubber balloon main body 510 with the small diameter portion 210 of the blowing balloon member 1000 for the rubber balloon. At this time, a gap is formed between the spherical body 300 that is a check valve and the small-diameter portion 210 with the force of blowing air.

ゴム風船本体510に空気が十分に吹き込まれた状態で小径部210から口を外しても、ゴム風船本体510に充填された空気によって逆止弁たる球体300が小径部210側に押しやられて小径部210が閉ざされる。その結果、ゴム風船本体510の口部511を押さえなくても、ゴム風船本体510から空気が漏れだすことはない。   Even when the mouth is removed from the small-diameter portion 210 in a state where air is sufficiently blown into the rubber balloon main body 510, the spherical body 300 serving as a check valve is pushed toward the small-diameter portion 210 by the air filled in the rubber balloon main body 510 and has a small diameter. Part 210 is closed. As a result, air does not leak from the rubber balloon body 510 without pressing the mouth 511 of the rubber balloon body 510.

また、ゴム風船用吹込み口部材1000にはフィルター400がセットされているので、口で空気を吹き込んでも唾液はゴム風船本体510の内部には吹き込まれることはない。従って、ゴム風船500を飛翔させたとしても、感染症の原因となるウィルスをまき散らすおそれがない。また、ゴム風船500に空気を吹き込んでいる最中、または飛翔させるために保持している最中になんらかの原因でゴム風船500を破裂させたとしても、感染症の原因となるウィルスをまき散らすおそれがない。 Further, since the filter 400 is set on the rubber balloon blowing port member 1000 , saliva is not blown into the rubber balloon main body 510 even if air is blown through the mouth. Therefore, even if the rubber balloon 500 is caused to fly, there is no risk of spreading a virus that causes infection. Moreover, even if the rubber balloon 500 is ruptured for some reason while air is being blown into the rubber balloon 500 or being held for flight, there is a risk of spreading a virus that causes infection. Absent.

ゴム風船500を飛翔させる際には、ゴム風船用吹込み口部材1000を片手で持ちつつ、ゴム風船500のノズル部材520をもう一方の手の指で押し出して、ゴム風船500のノズル側連結部522Bをゴム風船用吹込み口部材1000の連結部110から外せばよい。 When the rubber balloon 500 is caused to fly, the nozzle member 520 of the rubber balloon 500 is pushed out with the finger of the other hand while holding the rubber balloon blowing port member 1000 with one hand, and the nozzle side connecting portion of the rubber balloon 500 What is necessary is just to remove 522B from the connection part 110 of the blowing port member 1000 for rubber balloons .

なお、上述した実施の形態では、1つのゴム風船用吹込み口部材1000に1つのゴム風船500を連結させるとしたが、図6(A)に示すように、1つのゴム風船用吹込み口部材1000Bに複数(図面では3つ)の連結部110Bを形成すれば、3つのゴム風船500を同時に飛翔させることができる。 In the embodiment described above, although the linking of one balloon 500 to one balloon for blowing port member 1000, as shown in FIG. 6 (A), blowing port for one balloon If a plurality (three in the drawing) of connecting portions 110B are formed on the member 1000B , the three rubber balloons 500 can fly simultaneously.

また、図6(A)に示すゴム風船用吹込み口部材1000Bは、空気を吹き込む際に口でくわえる小径部210Bは1つであるため、3つのゴム風船500に同時に空気を吹き込むことになるので、肺活量の小さい子どもや女性には使いづらい面があるが、図6(B)のように、1つのゴム風船用吹込み口部材1000Cに複数(図面では3つ)の連結部110Cを形成するとともに、各連結部110Cに独立して繋がった3つの小径部210Cを形成すれば、肺活量の小さい子ども等であっても、複数のゴム風船500を同時に飛翔させることができるにも関わらず、子ども等にも使いやすいものとなる。 In addition, since the rubber balloon blowing port member 1000B shown in FIG. 6A has one small diameter portion 210B that is added by the mouth when air is blown, the air is simultaneously blown into the three rubber balloons 500. Therefore, although it is difficult to use for children and women with small vital capacity, as shown in FIG. 6B, a plurality of (three in the drawing) connecting portions 110C are formed on one rubber balloon blowing port member 1000C. In addition, by forming three small diameter portions 210C that are independently connected to each connecting portion 110C, even if the child has a small vital capacity, a plurality of rubber balloons 500 can fly simultaneously, Easy to use for children.

また、他のゴム風船用吹込み口部材としては、複数の連結部を有するが、小径部は1つであり、吹込み経路を連結部ごとに切り換えることができる切換機構を内蔵したものもありうる。 In addition, as another rubber balloon blowing port member, there are a plurality of connecting portions, but there is one small-diameter portion and a built-in switching mechanism that can switch the blowing path for each connecting portion. sell.
