Pouring spout for dispensing a liquid present in a liquid container
A pouring spout for dispensing a liquid present in a liquid container is provided. The pouring spout includes a first tubular body for connecting to the liquid container and a second tubular body which together with the first tubular body forms a passage for dispensing the liquid. The first and second tubular bodies are telescopically movable here relative to each other for leaving clear a radial opening through which the liquid can leave the pouring spout. The pouring spout further includes a venting channel for drawing in air. The invention is characterized in that the venting channel is fixedly connected to the second tubular body.
1. A pouring spout for dispensing a liquid present in a liquid container, comprising:
a first tubular body which is adapted at an end thereof for placing on the liquid container;
a second tubular body which together with the first tubular body forms a passage for dispensing the liquid;
a closing part placed in axial direction at a distance from the first tubular body, wherein the first and second tubular bodies can move telescopically relative to each other between an open and closed position, wherein in the open position the second tubular body leaves an opening at least partially clear between the closing part and the first tubular body and wherein in the closed position the second tubular body blocks the opening; and
a venting channel for supplying air from outside to the liquid container, which channel extends at least partially in the first tubular body, said venting channel being fixedly connected to the second tubular body;
wherein:
the closing part comprises a transversely extending closing surface that is configured to simultaneously close or open the venting channel and the passage when arranging the first and second tubular bodies from the open position to the closed position and when arranging the first and second tubular bodies from the closed position to the open position, respectively; and
the second tubular body has on an end remote from the first tubular body an axial opening, which axial openings of the second tubular body and the venting channel are blocked in the closed position by the closing surface of the closing part.
2. The pouring spout as claimed in claim 1 , wherein the opening is a radial opening.
3. The pouring spout as claimed in claim 1 , wherein in the closed position the second tubular body lies against the closing part for the purpose of closing the passage in axial direction.
4. The pouring spout as claimed in claim 1 , wherein the venting channel is formed by a tubular element.
5. The pouring spout as claimed in claim 1 , wherein the second tubular body is placed slidably round an outer end of the first tubular body.
6. The pouring spout as claimed in claim 1 , wherein the second tubular body has in axial direction a step in internal dimension which forms a stop for limiting the telescopic movement of the first and second tubular bodies.
7. The pouring spout as claimed in claim 1 , wherein the closing part is fixedly connected to the first tubular body.
8. The pouring spout as claimed in claim 7 , wherein the closing part further comprises an axial connecting part which extends from the closing surface to the first tubular body and is coupled thereto.
9. The pouring spout as claimed in claim 8 , further comprising a spring placed between the axial connecting part and the first tubular body.
10. The pouring spout as claimed in claim 9 , wherein the first tubular body and the axial connecting part both comprise a support, between which supports the spring is placed.
11. The pouring spout as claimed in claim 1 , wherein the venting channel comprises means for at least locally limiting the throughflow speed of air and/or at least locally limiting the entry of the liquid.
12. The pouring spout as claimed in claim 11 , wherein the venting channel has a locally smaller inner dimension at an end remote from the closing part.
13. The pouring spout as claimed in claim 11 , further comprising a non-return valve received in the venting channel for the purpose of preventing liquid entering the venting channel from the liquid container.
14. The pouring spout as claimed in claim 11 , wherein the venting channel has a locally smaller inner dimension at an end thereof.
15. The pouring spout as claimed in claim 1 , further comprising a resilient element for placing the telescopic movement between the first and second tubular bodies under spring tension.
16. The pouring spout as claimed in claim 1 , wherein the second tubular body is provided with a body protruding in radial direction which is suitable for being engaged by an opening edge of a receiving liquid container for the purpose of moving to the open position.
17. The pouring spout as claimed in claim 1 , wherein the venting channel and the second tubular body are formed integrally.
