Abstract (en)
[origin: JPS6445266A] PURPOSE: To exactly set a container from its seal condition to the discharge condition by furnishing the inside of a cap with a cylindrical core which has a knife for cutting a seal lid stuck on a pourer aperture, moving the cylindrical core in the axial direction by removal of a certificate band in the lower section of the cap to undergo unsealing, and keeping the cylindrical core in an unsealed state. CONSTITUTION: A plug element 4 has a cylindrical crown 5 with a cam groove 6 and is connected to a cylindrical core 10 by a continuous spacer 9. The core forms a part of the plug 4 and is introduced into a cylindrical guide 12 in the vicinity of a top portion 11. In order that the cylindrical core 10 can pass from the start position to a completely pushed position by removal of a certificate band 3, polypropylene having sufficient flexibility is used for the spacer 9 for forming a hinge and gives which characteristics to a knife 14. A turning cap 7 makes the spacer 9 impossible to return the initial position of cylindrical core 10 when it reaches the lowest position, so that a pourer aperture provided in the top of the cap 7 can be opened and closed.
