ABSTRACT:
A plastic cap assembly with a base cap and a cap that is formed in one piece and may be installed on the neck of the container that is sealed with a foil or a membrane. A projection in the flat wall of the base cap has on its underside a penetrator with which the foil can be penetrated. The contents of the container can then flow through the hole in the foil from the penetrator to the pour opening. The cap assembly is simple to operate and to produce; it supports the foil and in addition can be safety sealed. It is particularly well-suited for containers used for readily oxidizable foodstuffs such as ketchup, for example.
