Abstract

The present invention relates to a dispenser for dispensing a liquid, comprising: a reservoir for storing a liquid to be dispensed; a manually operative pump arrangement disposed at a first end region of the reservoir; a conduit extending from the pump arrangement to a second end region of the reservoir distal the first end region, the conduit configured for communicating reservoir contents from the second end region to the pump arrangement; a dispense conduit extending from the pump arrangement and comprising a dispense aperture at an end region thereof, the dispense aperture in liquid communication with the pump arrangement; and an open ended tube extending in a direction away from the pump arrangement and configured to surround the dispense conduit, wherein the open ended tube extends to a position such that the open end thereof is at least coterminous with an dispense aperture end of the dispense conduit and actuation of the pump arrangement causes transfer of reservoir contents from the reservoir to the dispense aperture end of the dispense conduit.

First claim

The invention claimed is:

1. A dispenser for dispensing a liquid into a cartomiser for a smoking substitute device, the dispenser comprising:
a reservoir for storing a liquid to be dispensed;
a manually operative pump arrangement disposed at a first end region of the reservoir;
a conduit extending from the pump arrangement to a second end region of the reservoir distal the first end region, the conduit configured for communicating reservoir contents from the second end region to the pump arrangement;
a dispense conduit extending from the pump arrangement and comprising a dispense aperture at an end region thereof, the dispense aperture in liquid communication with the pump arrangement; and
an open ended tube extending in a direction away from the pump arrangement and configured to surround the dispense conduit and to receive a mouthpiece portion of the cartomiser, wherein the open ended tube extends to a position such that the open end thereof is at least coterminous with a dispense aperture end of the dispense conduit and actuation of the pump arrangement causes transfer of reservoir contents from the reservoir to the cartomiser through the dispense aperture end of the dispense conduit and the mouthpiece of the cartomiser,
wherein the dispenser is further configured to receive a cap to close the open ended tube,
wherein an exterior and/or interior wall of said open ended tube is configured for engagement with a portion of said cap,
wherein the dispenser further comprises a plug member, a portion of which is configured for engagement with the exterior and/or interior wall of said open ended tube, and
wherein said plug member comprises engagement formations configured to receive complementary engagement formations of a removal device, wherein said removal device comprises the cartomiser.

2. A dispenser according to claim 1 , wherein the open ended tube extends to a position beyond the dispense aperture end of the dispense conduit.

3. A dispenser according to claim 1 , wherein the dispense conduit is configured to interface with a complementary arrangement in the cartomiser to deliver reservoir contents into the cartomiser.

4. A dispenser according to claim 1 , wherein the dispense conduit is configured to penetrate into the cartomiser to deliver reservoir contents into the cartomiser.

5. A dispenser according to claim 4 , wherein the dispense conduit is configured to pierce a membrane of the cartomiser to protrude into the cartomiser to deliver reservoir contents into the cartomiser.

6. A dispenser according to claim 1 , wherein the cap is a child safety cap.

7. A dispenser according to claim 1 , wherein said exterior and/or interior wall comprises engagement formations configured for engagement with complementary engagement formations of said cap.

8. A dispenser according to claim 1 , wherein said plug member is removable from said dispenser, when engaged to said removal device, by a pulling action exerted on the removal device.

9. A dispenser according to claim 1 , wherein the pump arrangement is resiliently biased towards a closed position.

10. A dispenser according to claim 1 , wherein the pump arrangement comprises an abutment surface configured to engage with a complementary surface of the cartomiser and wherein application of a force to the abutment surface actuates the pump arrangement.

11. A dispenser according to claim 10 , wherein application of the force is against a resilient bias.

12. A dispenser according to claim 1 , wherein the open ended tube is profiled so as to guide the cartomiser into engagement with the dispense conduit.

13. A dispenser according to claim 12 , wherein the open ended tube is profiled so as to provide a transition fit for engagement of the cartomiser for reciprocal movement of the cartomiser with respect to the open ended tube.

14. A dispenser according to claim 12 , wherein an inner wall of the open ended tube is profiled so as to guide the cartomiser.

15. A dispenser according to claim 12 , wherein the open ended tube is profiled so as to receive a mouthpiece for a smoking substitute device.

16. A dispenser according to claim 15 , wherein the open ended tube is profiled to provide a complementary cross-section for the mouthpiece for the smoking substitute device.

17. A dispenser according to claim 1 , wherein a surface of the open ended tube is coated with an antibacterial coating.

18. A dispenser according to claim 1 , wherein the pump mechanism dimensions are configured to deliver a measured dose of reservoir contents for a full pump stroke length.

19. A dispenser according to claim 18 , configured to provide feedback indicative of reaching a maximum stroke length, wherein the feedback may be one or more of tactile, visual, and audio feedback.

20. A dispenser according to claim 1 , wherein the open ended tube is configured with a locking or a positive engagement mechanism configured to permit a reciprocal movement of the cartomiser when engaged therewith.

21. A dispenser according to claim 1 , wherein the pump arrangement comprises a locking or positive engagement mechanism, interoperable with a complementary mechanism on the cartomiser to avoid inadvertent separation of the cartomiser from the pump arrangement.

22. A kit of parts for forming an assembly for filling a container, comprising
a dispenser according to claim 1 ; and
a container operative with the dispenser for filling the container, the container comprising:
a storage cavity for storing reservoir contents dispensed to the container from the dispenser;
an interface formation configured to receive the dispense conduit of the dispenser to open a conduit between the storage cavity and pump arrangement to permit transfer of reservoir contents from the pump arrangement to the storage cavity responsive to actuation of the pump arrangement; and wherein
the interface formation is disposed in an interface section of the container configured to fit to the open ended tube in order for the dispense conduit to engage with the interface formation.
