従来のコンドームのピンホールの検査方法は、
でき上つて脱型したコンドームを再度金属の型に
はめ込み、それを水に浸けて金属の型と水との間
の漏電状態を判別することにより、コンドームの
ピンホールの検査を行なつていた。[Detailed Description of the Invention] The conventional condom pinhole inspection method is as follows:
Condoms were tested for pinholes by inserting the completed condom into a metal mold, immersing it in water, and determining the state of electrical leakage between the metal mold and the water.
このような従来の検査方法によると、金属の型
にコンドームを装着するために多くの労力を要
し、また、コンドームと金属の型との間に空気層
が有つて密着性が悪い場合には、ピンホールが存
在しても空気層で絶縁されるので、検査もれを生
ずることがあつた。 According to these conventional testing methods, it takes a lot of effort to attach the condom to the metal mold, and if there is an air gap between the condom and the metal mold, which causes poor adhesion, Even if a pinhole existed, it was insulated by an air layer, which sometimes caused inspection failures.
一般的なコンドームの製造方法は、ラテツクス
または合成樹脂などの液状物へ製造型を浸漬し、
製造型の表面に付着したラテツクスなどを加熱し
て硬化せしめ、しかるのちに製造型よりコンドー
ムを外すのである。 A typical condom manufacturing method involves dipping a manufacturing mold into a liquid material such as latex or synthetic resin.
The latex adhering to the surface of the mold is heated and hardened, and the condom is then removed from the mold.
製造型よりコンドームを外す場合には、製造型
とコンドームとの間に水を入れて、製造型よりコ
ンドームを剥離する方法が一般に行なわれてい
る。 When removing a condom from the manufacturing mold, a common method is to put water between the manufacturing mold and the condom and peel the condom from the manufacturing mold.
そこで、この発明は、製造型とコンドームの間
に水を入れて、コンドームを外す工程を利用して
コンドームのピンホールの有無を検査するもので
あつて、従来のピンホールの検査方法が有してい
た問題点を解決したものである。 Therefore, the present invention inspects the presence or absence of pinholes in a condom by using the process of pouring water between a production mold and a condom and removing the condom, which conventional pinhole inspection methods have. This solves the problems that existed.

支持される。 As shown in Figure 1, the finished condom 2
When removing the condom 2 from the mold 1, the condom 2 is immersed in a conductive liquid, such as water 3, up to the mouth of the condom 2, and placed in a mesh container or porous wall so as to surround the outside of the condom 2. As shown in FIG. 2, when the condom 2 is received in a container 5 having a It is supported in a state where it is attached to the inner wall of 5.
そして、第３図に示すように、容器５で支持さ
れたコンドーム２の中の水４とコンドーム２の外
側との水３との間に、電流検知器６を介して電源
７より電圧を印加する。 Then, as shown in FIG. 3, a voltage is applied from a power source 7 via a current detector 6 between the water 4 in the condom 2 supported by the container 5 and the water 3 on the outside of the condom 2. do.
このとき、コンドーム２の中の水４とコンドー

る。 At this time, the water 4 inside the condom 2 and the water 3 outside the condom 2 should be electrically insulated via the condom 2, but the condom 2
If there is a pinhole in the condom, the water 4 inside the condom 2 and the water 3 outside are electrically connected through the pinhole, and a current flows.The leakage current is detected by the current detector 6. By doing so, the presence or absence of pinholes can be inspected.
このような電流検知器６としては、数10μＡで
もグロー放電して発光するネオン管６１のような
冷陰極放電管を採用し、電源７にネオン管６１の

光させることができる。 Such a current detector 6 employs a cold cathode discharge tube such as a neon tube 61 that glow discharges and emits light even at a few tens of μA, and generates a voltage higher than the discharge starting voltage of the neon tube 61 in the power source 7. By connecting the pinhole, it is possible to emit light even with a minute current flowing through the pinhole.
そして、このネオン管６１の発光を光電変換素
子６２で電気信号に変換して増幅６３したのち、
不良コンドームを排除する機構を駆動すればよい
のである。 Then, the light emitted from the neon tube 61 is converted into an electrical signal by a photoelectric conversion element 62 and amplified 63, and then
All that is required is to drive a mechanism that eliminates defective condoms.

た作用効果を奏することができる。 As explained above, according to the testing method of the present invention, the finished condom can be tested using the process of removing it from the manufacturing mold, so testing can be automated, and it is also possible to Since the test is carried out by filling it with water, there is no air space, and excellent effects such as no missed tests can be achieved.
