Abstract

A closure device for a container with a container opening has a lid element for closing the container opening, a chamber assigned to the lid element and an inner housing. The chamber and the inner housing have closing and opening elements that correspond to one another. The chamber locks with the inner housing, the lock with the inner housing being offset radially inwards in respect of a vertical of the closure device over a greatest width of the chamber in the offset direction. In order to specify a closure device which allows emptying of the chamber as the lid element is removed in an easy-to-handle fashion, with further preferred favorable manufacturability of the closure device, the lock in the vertical direction is designed separately from a shoulder section of the inner housing formed on the base side under the lock.

First claim

The invention claimed is:

1. A closure device ( 1 ) for a container ( 2 ) with a container opening ( 10 ), comprising; a lid element ( 3 ) configured for closing the container opening ( 10 ), a chamber ( 4 ) assigned to the lid element ( 3 ) and an inner housing ( 5 ), wherein the chamber ( 4 ) and the inner housing ( 5 ) have closing and opening elements that correspond to one another and interact with one another in such a way that a medium contained in the chamber ( 4 ) can exit into the container ( 2 ) due to a movement of the lid element ( 3 ) relative to the inner housing ( 5 ), wherein the chamber ( 4 ) has a freely projecting closure edge, which in a usage state is directed into a container interior, circumferentially extends around a central axis of the chamber ( 4 ) in an annular manner and in the closed state interacts with the inner housing ( 5 ) in a closing manner, wherein the inner housing ( 5 ) forms a chamber bottom ( 14 ) that is delimited by the closure edge, wherein the chamber bottom ( 14 ) forms a channel ( 15 ) that extends around an entire circumference of the chamber bottom and which is delimited by a radially inner channel side wall ( 16 ), a radially outer channel side wall ( 17 ) and a channel bottom ( 18 ), wherein the chamber ( 4 ) forms a discharge nozzle ( 11 ) having an annular end region that is permanently seated in a sealing element ( 22 ) disposed in the channel ( 15 ) so as to be not displaceable in a vertical direction (x), wherein the chamber ( 4 ) is interlocked with the inner housing ( 5 ), and wherein the interlock ( 6 ) with the inner housing ( 5 ) is with respect to a vertical central axis (x) of the closure device ( 1 ) offset radially inward in relation to a greatest inner width (k) of the chamber ( 4 ) in an offset direction (L), wherein the interlock ( 6 ) is in the vertical direction (M) designed separately from a shoulder section ( 40 ) of the inner housing ( 5 ), which is formed on the bottom side underneath the interlock ( 6 ) and functionally connected to the container opening ( 10 ).

2. A closure device ( 1 ) for a container ( 2 ) with a container opening ( 10 ), comprising: a lid element ( 3 ) for closing the container opening ( 10 ), a chamber ( 4 ) assigned to the lid element ( 3 ) and an inner housing ( 5 ), wherein the chamber ( 4 ) and the inner housing ( 5 ) have closing and opening elements that correspond to one another and interact with one another in such a way that a medium contained in the chamber ( 4 ) can exit into the container ( 2 ) due to a movement of the lid element ( 3 ) relative to the inner housing ( 5 ), wherein the chamber ( 4 ) has a freely projecting closure edge, which in a usage state is directed into a container interior, circumferentially extends around the central axis of the chamber ( 4 ) in an annular manner and in the closed state interacts with the inner housing ( 5 ) in a closing manner, wherein the inner housing ( 5 ) forms a chamber bottom ( 14 ) that is delimited by the closure edge, wherein the chamber ( 4 ) furthermore is composed of two parts ( 8 , 9 ) and has a partition plane (E) that extends perpendicular to a vertical central axis (x) of the closure device ( 1 ), and wherein the partition plane (E) extends through an overlapping section ( 41 ) of the lower part ( 9 ) of the chamber ( 4 ), or the closure device ( 1 ) according to claim 1 , wherein the two parts ( 8 , 9 ) are welded to one another in the partition plane (E), wherein the welded joint is produced by a supplementary section ( 36 ) that is connected to both parts ( 8 , 9 ) and produced by overmoulding, wherein the supplementary section ( 36 ) is designed annularly, and wherein a cross-sectionally outer circumferential wedge surface is cut into the edge region of the upper part ( 8 ) in order to accommodate the supplementary section ( 36 ) produced by overmoulding the region or that the supplementary section ( 36 ) is with respect to a cross section protracted radially outward and accordingly protrudes beyond the facing outer edge delimitation of the upper and the lower part ( 8 , 9 ).

3. The closure device according to claim 1 , wherein the interlock ( 6 ) is formed on a free-standing cylinder section ( 42 ) of the inner housing ( 5 ).

4. The closure device according to claim 1 , wherein the chamber ( 4 ) consists of a vertically upper part ( 8 ) and a vertically lower part ( 9 ) and is interlocked with the lid element ( 3 ) and the inner housing ( 5 ) on two planes (F, G), which with respect to the usage state of the closure device ( 1 ) are separated from one another in the vertical direction (M), by forming catch projections ( 30 , 32 ) and catch recesses ( 31 , 33 ) on the chamber ( 4 ), the lid element ( 3 ) and the inner housing ( 5 ), wherein the interlock ( 6 ) with the inner housing ( 5 ) is with respect to the vertical central axis (x) of the closure device ( 1 ) offset radially inward relative to the interlock ( 7 ) with the lid element ( 3 ), and wherein the catch projections ( 30 , 32 ) and catch recesses ( 31 , 33 ) of the planes (F, G) extend without overlapping one another in a projection into a common plane (H) transverse to the vertical axis (x).

5. The closure device according to claim 4 , wherein the catch projections ( 30 , 32 ) are formed on the vertically lower part ( 9 ).

6. The closure device according to claim 5 , wherein both parts ( 8 , 9 ) consist of a rigid plastic.

7. The closure device according to claim 6 , wherein both parts ( 8 , 9 ) contain polybutylene terephthalate.

8. The closure device according to claim 2 , wherein the supplementary section ( 36 ) is designed with a rear engagement ( 37 , 38 ) with respect to a vertical section, in which the vertical central axis (x) is illustrated in the form of a line.

9. The closure device according to claim 2 , wherein the supplementary section ( 36 ) is designed essentially triangular or trapezoidal with respect to the vertical section.

10. The closure device according to claim 2 , wherein the supplementary section ( 36 ) clamps together the two parts ( 8 , 9 ) in the vertical direction.

11. A closure device ( 1 ) for a container ( 2 ) with a container opening ( 10 ), comprising: a lid element ( 3 ) configured for closing the container opening ( 10 ), a chamber ( 4 ) assigned to the lid element ( 3 ) and an inner housing ( 5 ), wherein the chamber ( 4 ) and the inner housing ( 5 ) have closing and opening elements that correspond to one another and interact with one another in such a way that a medium contained in the chamber ( 4 ) can exit into the container ( 2 ) due to a rotational movement of the lid element ( 3 ) relative to the inner housing ( 5 ), wherein the chamber ( 4 ) has a freely projecting closure edge, which in a usage state is directed into a container interior, circumferentially extends around a central axis of the chamber ( 4 ) in an annular manner and in the closed state interacts with the inner housing ( 5 ) in a closing manner, wherein the inner housing ( 5 ) forms a chamber bottom ( 14 ) that is delimited by the closure edge, the chamber bottom transforming into a channel ( 15 ) over a circumference, channel being delimited by a radially inner channel sidewall 16 and a radially outer channel sidewall ( 17 ), wherein the chamber ( 4 ) is interlocked with the inner housing ( 5 ), and wherein the interlock ( 6 ) with the inner housing ( 5 ) is with respect to a vertical central axis (x) of the closure device ( 1 ) offset radially inward in relation to a greatest width (k) of the chamber ( 4 ) in an offset direction (L), wherein the interlock ( 6 ) is in the vertical direction (M) designed separately from a shoulder section ( 40 ) of the inner housing ( 5 ),
