本考案は浸漬成形用のコンドーム成形型の改良
に関するものである。[Detailed Description of the Invention] The present invention relates to an improvement of a condom mold for dip molding.
従来コンドームの胴部に角ばつた凸起又は凸条

状を呈していた。従つて、第１図に示す如く、こ
の成形型を使用してコンドームを浸漬成形する

め、該部分より破損する欠陥があつた。 Conventionally, in order to obtain angular protrusions or protrusions on the body of a condom, the edges of the recesses of the molds were carved at right angles on the outer peripheral surface of the mold. It was exhibiting a condition. Therefore, as shown in Fig. 1, when a condom is dip-molded using this mold, this right-angled edge A 3 acts to strengthen the surface tension, so that the solution adhering to this area will not adhere to other smooth surfaces. Formed thinner than surface a2 . As a result, the protrusion of the condom B molded from this mold, the base b' of the protrusion b, becomes thin, and pinholes occur in this part, and pressure concentrates on this part during use. There was a defect that caused the part to break.
本考案は斯る穴陥に鑑みて考案されたものであ

コンドーム溶液の表面張力を弱めて、溶液が凹窪
の縁部に、他の部分（成形型の平滑面）と同一の
肉厚で被着するようにしたものである。 The present invention was devised in view of such holes, and its gist is to provide a recess for forming a protrusion or a protrusion on the outer circumferential surface of the main body, and to form a recess at the edge of the recess. This is related to a condom mold that has an arc-shaped surface tension-weakened part by scraping off the flesh.The surface tension-weakened part weakens the surface tension of the condom solution that is sucked into the recess, and the solution is applied to the edge of the recess with the same thickness as the other part (the smooth surface of the mold).
以下本考案の実施例を図面について説明する
と、第２図は成形型の本体Ａを示し、この本体Ａ
の外周面には格子状に凹窪ａが穿設されており、
この凹窪ａの縁部は円弧状に削り取られている。
この凹窪ａの円弧状縁部を表面張力弱少部a1とす
る。 The embodiment of the present invention will be explained below with reference to the drawings. Fig. 2 shows the main body A of the mold, and this main body A
A grid-like recess a is bored on the outer circumferential surface of the
The edge of this recess a is cut into an arc shape.
The arcuate edge of this recess a is defined as a surface tension-weakening portion a1 .
この表面張力弱少部a1は本体Ａ（ガラス製）に
凹溝ａを腐蝕成形後、再度濃度が高い腐蝕液（フ
ツ化水素と塩素との溶液）中に本体Ａを浸漬せし
めて成形する。 This low surface tension area a1 is formed by etching grooves a on the main body A (made of glass) and then immersing the main body A in a highly concentrated corrosive solution (a solution of hydrogen fluoride and chlorine) again. .
なお凹窪ａは図示するものに限定されるもので
ない。即ち例えば独立状の小凹窪、環状凹溝−な
ど本体Ａの外周面を穿設するものであればその形
状は任意に選定されるものである。 Note that the recess a is not limited to what is illustrated. That is, the shape may be arbitrarily selected as long as the outer peripheral surface of the main body A is bored, such as a small independent depression or an annular groove.
斯して本案成形型を使用しコンドームを浸漬成
形すると、コンドーム成形溶液Ｂは凹窪ａの縁部
に設けた表面張力弱少部a1に本体Ａの平滑面a2と
同一の厚みで付着する（第３図）。 When a condom is dip-molded using the present mold, the condom molding solution B adheres to the surface tension-weakened area a1 provided at the edge of the recess a with the same thickness as the smooth surface a2 of the main body A. (Figure 3).
本考案コンドーム成形型は叙上の如く構成した
から、本成形型よりコンドームを浸漬成形する
と、凹窪によつて形成される凸起、凸条において
その付け根の肉厚がコンドーム本体の肉厚と略同
一に形成され、従来型の如き、凹窪内にコンドー
ム成形溶液が吸引され凹窪の縁部が肉薄状になる
ことがない。従つて本考品で成形したコンドーム
はその全体が均一の肉厚で形成され、ピンホール
の起生、使用中による破損…等生じる憂いがない
強靭なコンドームを成形できる。 Since the condom mold of the present invention is constructed as described above, when a condom is dip-molded using this mold, the thickness of the base of the protrusions and ridges formed by the depressions and ridges is equal to the thickness of the condom body. They are formed almost identically, and unlike the conventional type, the condom molding solution is not sucked into the recesses and the edges of the recesses do not become thin. Therefore, the condom molded with this product has a uniform thickness throughout, and it is possible to mold a strong condom without the problems of pinholes, breakage during use, etc.

The drawings show an embodiment of the present invention; FIG. 1 is a partially enlarged sectional view of a conventional product, FIG. 2 is a partially cutaway front view, and FIG. 3 is an enlarged sectional view thereof. In the figure, A indicates the main body, a indicates the recess, and a 1 indicates the portion where the surface tension is low.
