Abstract
A closure (1) for a fluid container, particularly for water bottles (9) in driking water dispensers has an aperture (3) and a remobable hollow plug (4) of resilient plastics material fitting into the aperture in a sealing position and displaceable from the aperture, under pressure of an elongate member (11) of the dispensing apparatus, to an open position in which the fluid in the container can flow out through the elongate member. Preferably the elongate dispensing member fits into the hollow plug and is gripped and carried thereby so that when the elongate member is withdrawn, the plug is drawn back into the aperture to seal the container again.
Claims
1. A screw-threaded closure for fitting onto a screw-threaded opening of a container, the closure comprising a gasket for providing a fluid-tight seal with the container opening, an aperture for enabling fluid communication through the closure with the inside of the container, and a removable plug dimensioned and constructed to provide a fluid-tight seal in a sealing position when seated in the aperture and to be selectively removable, under action of a dispensing member, to an open position enabling fluid communication with the inside of the container through the dispensing member.
2. A closure according to claim 1, characterised in that the plug is displaceable between the sealing position and the open position by means of pressure applied to the plug by the dispensing member.
3. A closure according to claim 1, or 2, characterised in that the plug is adapted to reseat in the aperture under a reverse action of the dispensing member.
4. A closure according to any preceding claim, characterised in that the plug has a recess for receiving the dispensing member.
5. A closure according to claim 4, characterised in that the plug is hollow with an internal shape corresponding to the shape of the dispensing member.
6. A closure according to any one of the preceding claims, characterised in that the plug comprises a resilient flange arranged to resiliently grip the dispensing member.
7. A closure according to claim 6, characterised in that the flange grips the dispensing member so that when the dispensing member is moved from the communicating position to the sealing position, the plug is carried thereby from the communicating position to the sealing position.
8. A closure according to any one of the preceding claims, characterised in that the aperture comprises a hollow tube of substantially the same diameter as the plug so as to achieve a fluid seal .
9. A closure according to claim 8, characterised in that the plug and the hollow tube are provided with - 9 -
co-operating peripheral grooves and flanges to improve the hollow seal .
10. A closure according to any preceding claim, characterised in that the plug comprises a lip protruding radially around a circumference of the plug so as to abut a surface surrounding the aperture to limit the movement of the plug when it is being drawn into the sealing position.
11. A closure according to any preceding claim, when formed of a resilient plastics material.
12. A method of placing the interior of a fluid container in fluid communication with a fluid dispensing apparatus, the container being fitted in a fluid-tight manner with a screw-threaded closure having a gasket and comprising an aperture through which fluid may pass and a removable plug dimensioned and constructed to provide a fluid-tight seal in the aperture; the method comprising displacing the plug out of sealing engagement with the aperture to thereby permit fluid flow through the aperture.
13. A method according to claim 12 comprising moving an elongate dispensing member longitudinally through the aperture to engage the plug and to displace the plug into the interior of the container.
14. A method according to claim 12 or 13, for subsequently re-sealing the container characterised by the step of relocating the plug in sealing engagement with the aperture by withdrawing the dispensing member from the aperture.
15. A method according to any one of claims 12 to 14, wherein the step of displacing the plug is effected by mounting the container on a dispensing apparatus comprising the dispensing member.
16. A method according to claim 14, wherein the step of withdrawing the dispensing member comprises dismounting the container from dispensing apparatus comprising the dispensing member.
17. A method according to any one of claims 12 to 16 comprising using a closure according to any one of claims 1 to 11.
