Abstract

A cover device ( 2 ) for a drink container having an improved leak resistance comprises a basic assembly ( 9 ) which is provided with a drink opening ( 32 ) and a ring-shaped member ( 37 ), and a valve arrangement ( 20 ) for blocking or unblocking a passage to the drink opening ( 32 ) from a drink container side of the cover device ( 2 ). The valve arrangement ( 20 ) comprises a valve element ( 26 ) having a sleeve ( 60 ) with a slit ( 42 ), a circumference of the sleeve ( 60 ) being substantially similar to a circumference of the ring-shaped member ( 37 ). The leak resistance of the valve arrangement is further improved in that the sleeve ( 60 ) and the ring-shaped member ( 37 ) have a first diameter in the direction of the slit ( 42 ) and a second diameter perpendicular to the slit ( 42 ), wherein a ratio between the first and second diameters of the sleeve ( 60 ) is smaller than a ratio between the first and second diameters of the ring-shaped member ( 37 ).

First claim

The invention claimed is:

1. A cover device for a drink container, the cover device comprising:
a basic assembly having a drink opening and a ring-shaped member; a valve arrangement, extending outwardly from the basic assembly, comprising:
a valve element comprising:
a raised central portion comprising a slit; and
an outer ring-shaped portion which are connected to each other through an area of the valve element at a position where the valve element is hingably associated with the basic assembly through contact to the ring-shaped member,
a sleeve extending upward from the ring-shaped member, said sleeve enclosing said raised central portion, and
a plurality of strengthening ribs extending from the sleeve along a surface of the raised central portion toward said slit, said strengthening ribs positioned on opposing sides of said slit;

wherein sizing, positioning and orientation of the raised central portion and the outer ring-shaped portion of the valve element are realized for having a smaller total moment of force on the raised central portion than on the outer ring-shaped portion when the valve element is subjected to pressure from a side of the cover device which is intended to face the drink container, wherein the sleeve and the ring-shaped member each have a first diameter in the direction of the slit and a second diameter perpendicular to the slit, and wherein a ratio between the first and second diameters of the sleeve is smaller than a ratio between the first and second diameters of the ring-shaped member.

2. The cover device according to claim 1 , wherein the ring-shaped member is circular while the first diameter of the sleeve is smaller than the second diameter of the sleeve.

3. The cover device according to claim 1 , wherein the sleeve is circular while the first diameter of the ring-shaped member exceeds the second diameter of the ring-shaped member.

4. An assembly of a drink container and a cover device according to claim 1 , wherein the cover device is removably attached to the drink container.
