Claims
- 1. A dispensing device for dispensing liquid from a container, the dispensing device including a main body which includes an end wall having an internal side face directed towards the interior of the container and an external side face, a dispensing outlet, and a closure moveable relative to the main body between open and closed positions to selectively open and close the dispensing outlet, a chamber between the external side face and the dispensing outlet, a liquid transfer port in the main body for permitting liquid flow from the container interior to the chamber and a breather port in the main body providing communication between the container interior and the chamber, the liquid transfer port and the breather port being separate and spaced apart from the one another with the breather port being disposed above the liquid transfer port when in a dispensing orientation so as to form a static head pressure differential therebetween, the spacing between the breather port and the liquid transfer port together with the chamber being such as to provide for a continuous and controlled flow of liquid from the dispensing outlet.
- 2. A dispensing device according to claim 1 wherein the cross-sectional dimension of the liquid transfer port is greater than the cross-sectional dimension of the breather port.
- 3. A dispensing device according to claim 2 wherein said closure can close the open end of the tubular side wall.
- 4. A dispensing device according to claim 3 wherein said dispensing outlet is in said tubular side wall at a lower section thereof when in the dispensing orientation.
- 5. A dispensing device according to claim 1 where in the main body includes a generally tubular side wall extending from the external side face of the end wall, such that the end wall and at least part of the tubular side wall define the chamber.
- 6. A dispensing device according to claim 1 wherein said closure is pivotally connected to the main body for movement between the open and closed positions.
- 7. A dispensing device according to claim 6 wherein including one or more pins on one of either the main body or closure arranged to cooperate with respective one or more guides on the other either the main body or closure to guide on the closure during pivotal movement thereof.
- 8. A dispensing device according to claim 1 including flow control members which form a zone within the chamber containing the liquid transfer port and breather port.
- 9. A dispensing device according to claim 8 wherein said flow control members include two generally parallel spaced apart partition walls which project from the closure and are receivable in slots in the end wall of the main body.
- 10. A dispensing device according to claim 1 further including a flow control member associated with the liquid transfer port, the flow control member extending into the chamber and includes a wall adjacent to and above the liquid transfer port in the dispensing orientation.
- 11. A device according to claim 1, further including a safety catch operable to releasably retain the closure in the closed position.
- 12. A device according to claim 11, wherein the safety catch includes a resilient latch member on one of the closure or the main body adapted to cooperate with a detent on the other of the closure or the main body, the arrangement being such deformation of the latch member causes it to release from the detent.
- 13. A dispensing device for dispensing liquid from a container, the dispensing device including a main body which includes an end wall having an internal side face directed towards the interior of the container and an external side face, a dispensing outlet, and a closure moveable relative to the main body between open and closed positions to selectively open and close the dispensing outlet, a chamber between the external side face and the dispensing outlet, a liquid transfer port in the main body for permitting liquid flow from the container interior to the chamber and a breather port in the main body providing communication between the container interior and the chamber, the liquid transfer port and the breather port being separate and spaced apart from one another with the breather port being disposed above the liquid transfer port when in a dispensing orientation so as to form a static head pressure differential therebetween, the spacing between the breather port and the liquid transfer port together with the chamber being such as to provide for a continuous and controlled flow of liquid from the dispensing outlet, the cross-sectional dimension of the liquid transfer port being greater than the cross-sectional dimension of the breather port said closure closing the open end of the tubular side wall, said dispensing outlet is in said tubular side wall at a lower section thereof when in the dispensing orientation, said tubular wall extending in the region of the dispensing outlet so as to form a gutter which directs liquid within the chamber towards the dispensing outlet.
- 14. A dispensing device for dispensing liquid from a container, the dispensing device including a main body which includes an end wall having an internal side face directed towards the interior of the container and an external side face, a dispensing outlet, and a closure moveable relative to the main body between open and closed positions to selectively open and close the dispensing outlet, a chamber between the external side face and the dispensing outlet, a liquid transfer port in the main body for permitting liquid flow from the container interior to the chamber and a breather port in the main body providing communication between the container interior and the chamber, the liquid transfer port and the breather port being separate and spaced apart from one another with the breather port being disposed above the liquid transfer port when in a dispensing orientation so as to form a static head pressure differential therebetween, the spacing between the breather port and the liquid transfer port together with the chamber being such as to provide for a continuous and controlled flow of liquid from the dispensing outlet, the device further including a flow control member associated with the liquid transfer port, the flow control member extending into the chamber and including a curved side wall adjacent to and above the liquid transfer port in the dispensing orientation which is generally semi-circular in shape and an end wall, the curved side wall extending from the end wall of the dispensing device and overlies the liquid transfer port, the side wall being open at its underside which faces towards the dispensing outlet.
- 15. A dispensing device according to claim 14, further including means for limiting the pivotal movement of the closure relative to the main body of the device between the open and closed positions of the dispensing outlet, the limiting means including a pair of pins, each pin having a catching section, which engages with an abutment which defines a travel limit stop.
