Abstract

용기의 고무마개 제조공수가 대폭절감된 제조방법에 대해 개시한다. 이 제조방법은 고무마개(40)의 레그부(42)에 대응하는 형상의 제1캐비티(11)를 가지는 제1금형(10) 상면에 합성수지필름(43)가 고무수지(40a)를 적층하여 안착시키는 제1공정과, 제1캐비티(11) 내에 진입되는 돌기부(21)를 가지는 제2금형(20)을 제1금형(1 0)과 형합시켜서 고무수지(40a) 및 합성수지필름(43)을 제1캐비티(11)내에 진입시키고 합성수지필름(43)을 절단시키는 제2공정과, 제1금형(10)으로부터 제2금형(20)을 형개시키고 마개몸체(41)에 대응하는 형상의 제3캐비티(31)를 가지는 제3금형 (30)을 제1금형(10)에 형합시켜서 마개몸체(41)를 성형하는 제3공정으로 이루어진다. 제2공정에서 제1캐비티(11)의 가장자리 모서리(12)와 돌기부(21)가 선접촉되면서 합성수지필름(43)이 절단된다. 이러한 제조공정은 고무마개(40)를 성형시키는 동안 합성수지필름(43)이 절단되어 제조후 합성수지필름(43)을 별도로 절단시킬 필요가 없게 된다.Disclosed is a manufacturing method in which rubber stopper manufacturing labor of a container is greatly reduced. In this manufacturing method, the synthetic resin film 43 stacks the rubber resin 40a on the upper surface of the first mold 10 having the first cavity 11 having a shape corresponding to the leg portion 42 of the rubber stopper 40. A rubber mold 40a and a synthetic film 43 are formed by combining the second mold 20 having the first step of seating and the second mold 20 having the protrusion 21 entered into the first cavity 11 with the first mold 10. In the first cavity (11) to cut the synthetic resin film (43), and the mold of the shape corresponding to the stopper body (41) by opening the second mold (20) from the first mold (10). A third process is performed by molding the stopper body 41 by joining the third mold 30 having the three cavities 31 to the first mold 10. In the second process, the synthetic resin film 43 is cut while the edge edge 12 of the first cavity 11 and the protrusion 21 are in linear contact. In this manufacturing process, the synthetic resin film 43 is cut during molding the rubber stopper 40 so that the synthetic resin film 43 does not need to be separately cut after the production.
