Bottle-sealing cap assembly

摘要

The bottle-sealing cap comprises an inner actuating member (3) fitting in an outer sealing body incorporating a rounded head (4). A tubular sealing section (5) is expanded and contacted by the actuating member movement. An expanding section (6) inside the sealing one and between its ends assumes a position of equilibrium until the actuatin g member is pressed down. It can incorporate a stop (9) extending from a base (7) and in contact with the member, also a flexible portion (8) joining the base to the inside of the sealing section.
