Abstract

A dispenser for dispensing a liquid is disclosed. The dispenser comprises an outlet for dispensing a liquid, a reservoir for liquid, and a closure configured to engage with the dispenser and movable between a closed position in which the outlet is enclosed and an open position in which the outlet is not enclosed. The dispenser further comprises an arrangement for controlling liquid communication between the reservoir and the outlet, the arrangement and reservoir movable with respect to each other between a first configuration in which the reservoir is not in liquid communication with the outlet and a second configuration in which the reservoir is in liquid communication with the outlet. By requiring a second movement after removal of the closure accidental access or dispensing of the contents may be avoided or reduced.

First claim

The invention claimed is:

1. A dispenser for dispensing a liquid, comprising:
a reservoir for liquid, the reservoir deformable to permit pressure to be exerted on a liquid in the reservoir, the reservoir comprising:
a bottom wall and a top wall;
wherein the top wall includes a tubular guide member extending from an exterior into an interior of the reservoir;
a first aperture in a wall of the tubular guide member disposed in the interior of the reservoir;

a conduit assembly including:
a conduit with an outlet for dispensing a liquid; and
a second aperture in a wall of the conduit;
wherein the conduit is received in the tubular guide member to provide liquid communication between the reservoir and the outlet;

wherein the conduit assembly and reservoir are movable with respect to each other between a first configuration in which the conduit wall occludes the first aperture such that the reservoir is not in liquid communication with the outlet, and a second configuration in which, through alignment of the first and second apertures, the reservoir is in liquid communication with the outlet, the tubular guide member for guiding movement of the conduit between the first and second configurations;
a closure, including an engagement member disposed on the interior of the closure, engageable with the dispenser and movable between a closed position in which the outlet is occluded by the engagement member and an open position in which the outlet is not occluded;
a deformable housing for receiving the reservoir, the reservoir translatable with respect to the housing to bring the reservoir into liquid communication with the outlet; and
wherein the engagement member of the closure, while in the outlet non-occluded position, is engageable, through an aperture in a bottom of the housing, with the reservoir bottom for urging the conduit and reservoir from the first configuration to the second configuration for bringing the reservoir into liquid communication with the outlet and for maintaining the reservoir in liquid communication with the outlet to enable the liquid to be dispensed when pressure is exerted on the housing and the reservoir.

2. A dispenser according to claim 1 , wherein the reservoir and conduit are slideably movable with respect to each other between the first and second configuration.

3. A dispenser according to claim 1 , wherein an end of the conduit comprises the outlet.

4. A dispenser according to claim 1 , wherein the arrangement is constrained to be movable between the first and second configuration only while the closure is in the outlet non-enclosed position.

5. A dispenser according to claim 1 , wherein the closure is configured to engage with the reservoir for removably retaining the closure in a closed outlet position.

6. A dispenser according to claim 1 , wherein the closure and the reservoir comprise mutually cooperative engagement formations configured for removably retaining the closure in a closed outlet position.

7. A dispenser according to claim 1 , wherein the closure is configured to engage with the housing for removably retaining the closure in a closed outlet position.

8. A dispenser according to claim 1 , further comprising a bias mechanism configured to bias the reservoir away from the second configuration.

9. A dispenser according to claim 6 , wherein the mutually cooperative engagement formations comprise a detent arrangement movable between an engaged and disengaged position, wherein in the engaged position the closure is retained in the closed outlet position and in the disengaged position the closure is movable to the outlet non-enclosed position.
