Description
【考案の詳細な説明】 本考案は、環状ゴム風船の改良に関する。[Detailed explanation of the idea] The present invention relates to improvements in annular rubber balloons.
此の種の環状ゴム風船は、例えば意匠登録第３４１９２
１号のように公知であり、また、出願人は特願昭５４−
３２４３１号等で、二つ割れに接合分離できる型で環体

風船用液の皮膜を形成した後、型の接合部を分割し、皮
膜内より型を取り出す環状ゴム風船の製造技術を開示し
た。This type of annular rubber balloon is, for example, Design Registration No. 34192.
It is publicly known as No. 1, and the applicant has filed a patent application for
No. 32431 etc., a ring body is formed using a mold that can be joined and separated into two parts, the mold is immersed in a rubber balloon liquid, a film of the rubber balloon liquid is formed on the surface of the mold, and then the joined part of the mold is We have disclosed a manufacturing technology for annular rubber balloons in which the balloons are divided and the mold is taken out from within the membrane.
しかし乍ら、従来、このような製造法によって環状ゴム
風船を製造した場合には、環状ゴム風船の空洞部を構成
するゴム風船の内周面中、空気吹込口に対向する内周面
部が、ゴム風船を膨らました時に他の部分に比し強い加
圧又は負圧を受け、因って、該内周面部が破裂し易いと
いう欠点があった。However, conventionally, when an annular rubber balloon is manufactured by such a manufacturing method, in the inner peripheral surface of the rubber balloon constituting the hollow part of the annular rubber balloon, the inner peripheral surface facing the air inlet is When a rubber balloon is inflated, it receives stronger pressurization or negative pressure than other parts, and as a result, the inner peripheral surface part has a disadvantage that it is more likely to burst.
本考案は、かような実情に鑑みて創案されたものであり
、図面に示す如く、環状ゴム風船の空洞部４を構成する
ゴム風船の内周面中、ゴム風船の突気吹込口２に対向す
る内周面部を突出させて突出部３を形成し、因って、環
状ゴム風船１を膨らました時に生ずる該部分への加圧又
は負圧にも十分耐え得る構造とした。The present invention has been devised in view of the above-mentioned circumstances, and as shown in the drawing, a blow-in port 2 of the rubber balloon is provided in the inner peripheral surface of the rubber balloon constituting the hollow portion 4 of the annular rubber balloon. The protruding part 3 is formed by protruding the opposing inner circumferential surface parts, so that the structure can sufficiently withstand pressurization or negative pressure on the part generated when the annular rubber balloon 1 is inflated.
この場合、該突出Ｃは、環状の横幅ａが２０ｍｍ、縦幅
すが５ｍｍ程度の風船であれば５ｍｍ〜１０ｍｍあれば
良い。In this case, the protrusion C may be 5 mm to 10 mm if the balloon has an annular width a of about 20 mm and a vertical width of about 5 mm.
このように、本考案に係る環状ゴム風船は、空洞部を構
成する内周面の、空気吹込口に対向する内周面部に突出
部を形成しであるから、膨らました時に他の部分に比し
て強く働く該部分への加圧又は負圧にも十分耐えること
ができ、因って、破裂の原因が全く解消し得た。As described above, since the annular rubber balloon according to the present invention has a protrusion formed on the inner circumferential surface of the inner circumferential surface that forms the cavity and faces the air inlet, the annular rubber balloon has a protrusion that is smaller than the other parts when inflated. It was able to sufficiently withstand the pressurization or negative pressure exerted on the part, which is strongly applied, and therefore, the cause of rupture could be completely eliminated.
