Self-closing seal with a sealing membrane
First Claim
1. A self-closing closure for dispensing a product, said closure comprising:
- a closure cap including a through-passage opening formed therein; and
a closure membrane coupled to the closure cap proximate the opening, said closure membrane including;
a bottom retaining border;
a self-closing top closure head that is essentially concave and, in response to product pressure, is capable of axial movement with respect to the retaining border between a lower rest position and an upper dispensing position; and
a connecting wall and an inclined portion, said closure head being circumferentially coupled at a top end of the connecting wall, said inclined portion being coupled between said connecting wall and said retaining border, whereby said connecting wall and said inclined portion coupling said retaining border and said closure head together, said inclined portion forming an acute angle with a closure axis, said inclined portion being inclined downwards and inwards toward the product when the closure head is in its lower position and being movable in response to product pressure to an upwards and inwards inclined position when the closure head rises to its dispensing position.

Abstract
The invention relates to a self-closing closure with a closure cap (1), with a through-passage opening (8) formed in the closure cap (1), and with a closure membrane (2), assigned to the through-passage opening (8), the closure membrane (2) having a bottom retaining border (3) and a top, essentially concave closure head (5), the closure head (5) and the retaining border (3), furthermore, being connected by a connecting wall (4), and, for the purpose of achieving a solution which is favorable in terms of both usage and production, proposes that a widened region (9) adjoins the through-passage opening (8) towards the outside, that the closure head (5) is arranged in the widened region (9), and that the connecting wall (4) extends into the widened region (9), passing through the through-passage opening in the process.
