Method for making an easy opening container end closure |
摘要 |
A closure for closing the open end of a container having contents therein which dissociate a gas therefrom. The closure is adapted to provide an opening for access to the contents. The opening is adapted for a snap assembly with a plastic cap to effect a substantially gas-tight seal of the opening under high pressures to enable resealing of the container after dispensing a portion of the contents.
