生上問題があつた。Questions and Answers to be Solved by the Invention According to the former technique, the upper stopper and the lower stopper are simply fitted together, so when the stopper is assembled and welded to the mouth of a plastic container, it is difficult to There is a high risk of contamination during transportation, and therefore, the surface of the rubber stopper must be cleaned with alcohol after the pull-top is removed during use. In addition, according to the latter technology, the area around the rubber stopper can be sealed by injection molding, which is sanitary, but it is difficult to join the plastic thin film and the injection molded plastic, resulting in unwelded parts in some parts. Infusion fluid entered the rubber stopper through this unwelded portion, posing a sanitary problem.

そこで、本発明は以上の点の鑑み以下の目的を
達成しようとするものである。 In view of the above points, the present invention aims to achieve the following objects.

(1) 密封性の高い栓体を得ること ゴム栓を完全に密封して外気の雑菌から完全に
隔離して衛生性を高めること。(1) Obtaining a stopper with high sealing performance To improve hygiene by completely sealing the rubber stopper and completely isolating it from germs in the outside air.

(2) 上側栓と下側栓の溶着が完全であること 超音波溶着であるので、溶着する部材を選ばず
溶着でき、しかも溶着が完全である。(2) The welding of the upper and lower plugs is perfect. Since it is ultrasonic welding, it is possible to weld any part to be welded, and the welding is perfect.

(3) 栓体の衛生性が高いこと 問題点を解決するための手段 そこで、本発明は、 「天板部上側にプルリングを有し下側にスコア

In the method for manufacturing a stopper in which a rubber stopper is enclosed by a lower stopper having a thin plate portion at a position where the upper stopper and the lower stopper are brought into contact with each other on the sides of the rubber stopper, ultrasonic vibration is applied to the upper stopper. The plug and the lower plug are welded together.

The upper stopper 1 has a top plate part 11, has a pull ring 12 integrally on its upper side, and has a score 13 on its lower side. Further, the upper stopper 1 integrally has a circumferential protrusion 14 on the outside of the score, and further has a joining protrusion 15 on the outside of the circumferential protrusion 14. Lower plug 2 is upper plug 1
It has a thin plate 21 that can be easily penetrated with a metal needle at a position opposite to the top plate part of the plate, and has a cylindrical part 22 having a flange 23 at the tip extending downward on the outside thereof. The portion 22 has a joining protrusion 24 on the upper side. The rubber stopper 3 has a flat plate shape as a whole,
The circumferential protrusion 14 of the upper stopper 1 has a flat plate part 31 in the center.
At a position corresponding to , there is a circumferential groove 32 having a depth equivalent to the protruding length of the circumferential protrusion 14, and a circumferential protrusion 3 that protrudes upward on the outside of the circumferential groove 32.
It has 3. The circumferential protrusion 33 of this rubber stopper is
The height is slightly smaller than the height of the flat plate 31. The rubber stopper 3 is housed in a recess formed by the top plate 11 of the upper stopper 1 and the joint protrusion 15 and the thin plate 21 of the lower stopper 2 and the joint protrusion 24.

これら部材を第１図に示すように、先ず下側栓
２を、治具５の上に載置し、下側栓２を固定す

６が生じる。 Next, the tool horn 4 is hung down and the upper stopper 1 is placed over the rubber stopper 3 and the lower stopper 2, so that the joint projection 15 of the upper stopper 1 and the joint projection 24 of the lower stopper 2 are brought into contact with each other. At this time, as shown in FIG.
a, and the joint protrusion 24 of the lower stopper 2 has a sub-protrusion 24a on the outside. In addition, the sub-projection 15a of the upper plug
is formed longer than the subprojection 24a of the lower stopper. For this reason, when the two are brought into contact, a gap 6 is created on the outside.

する。 Next, an ultrasonic wave of about 20 KHz is applied to the tool horn 4, the amplitude is amplified by the tool horn 4, and the ultrasonic amplitude is transmitted to the upper stopper 1. This ultrasonic amplitude causes the joining protrusion 15 of the upper stopper and the joining protrusion 24 of the lower stopper.
Heat is generated at the contact surface between the two. The plastic melted by the pressure of the tool horn 4 is eluted toward the rubber stopper, presses the rubber stopper 3, and forms a protrusion 7, as shown in FIG. Ultrasonic waves are applied to the tool horn 14 until the gap 6 disappears and the contact surfaces weld together.

冷却して溶着が完了した後、工具ホーン４を除

ー効果が大きい。 According to the above embodiment, since welding is performed using ultrasonic waves, even if foreign matter such as moisture or oil is present on the contact surface between the upper plug 1 and the lower plug 2, welding can be performed, and this part can be welded. This means that there will be no unwelded parts. Therefore, the inside of the rubber stopper can be completely sealed and moisture and germs can be completely prevented from entering the rubber stopper. Further, in the above embodiment, since the protrusion 7 is formed, the rubber stopper 3 is connected by the outer upper stopper 1 and the lower stopper 2, so that the injection needle can be inserted into the rubber stopper 3. The rubber stopper 3 will not come off even when used.
Another embodiment is shown in FIG. This has a circumferential groove 34' on the outer surface of the circumferential protrusion 33' of the rubber stopper. The grooved line 34' is formed at a portion corresponding to the contact surface between the upper stopper 1 and the lower stopper 2. By forming this groove 34', it is possible to easily pour the plastic heated and eluted by ultrasonic amplitude. The grooved line 34' shown in FIG. 5 has a half-moon cross-sectional shape, but as shown in FIG.
If it is 4", it will be embedded in the rubber stopper 3", so the anchor effect will be great.

抜け防止を完全にできるのである。 In addition, as shown in Figure 6, by making the thickness of the rubber plug 3'' equal to that of the recess surrounded by the upper plug 1'' and the lower plug 2'', welding can be performed while compressing the rubber plug 3'' during welding. This makes it possible to completely prevent the rubber stopper from coming off.

上記実施例では、印加する超音波の振動数は
20KHzとしたが特にこの数値に限定されるもので
はないが、プラスチツクの溶着時間、溶着強度等
を考慮すると超音波の振動数は10〜30KHzが好し
くこれらの超音波を工具ホーンで増幅することよ
り10〜100μｍの振幅にするものが好しい。 In the above example, the frequency of the applied ultrasonic wave is
Although it is set at 20KHz, it is not limited to this value, but considering the welding time of plastic, welding strength, etc., the frequency of ultrasonic waves is preferably 10 to 30KHz, and these ultrasonic waves should be amplified with a tool horn. It is more preferable to have an amplitude of 10 to 100 μm.

発明の効果 本発明は以上のように構成したので、溶着を完
全にすることができ、したがつてゴム栓を完全に

衛生的に栓体を製造することができるものであ
る。Effects of the Invention Since the present invention is constructed as described above, the welding can be completed completely, and therefore the rubber stopper can be completely sealed and the stopper body can be produced in an extremely hygienic manner without allowing moisture to enter during sterilization. It is something that can be done.
