Abstract

A dispensing tap has a body which is attached or attachable to a container. The body has a dispensing orifice, and a piston movable within the body between a dispensing position in which flowable product can pass through the orifice and a sealing position in which fluid cannot pass through the orifice. The piston has one or more dispensing apertures through which product can pass when the piston is in the dispensing position to reach the dispensing orifice.

First claim

The invention claimed is:

1. A dispensing tap, comprising:
a body which is attached or attachable to a container, the body having a dispensing orifice and a tubular terminal dispensing conduit, and
a piston movable within the body between a dispensing position in which flowable product is passable through the dispensing orifice and a sealing position in which the flowable product is not passable through the dispensing orifice, wherein the piston comprises one or more dispensing apertures through which the flowable product is passable when the piston is in the dispensing position to reach the dispensing orifice,
wherein the dispensing conduit extends beyond the dispensing orifice, the dispensing orifice having a first cross-sectional shape and the dispensing conduit having a second cross-sectional shape, the first and second shapes being different from each other, and
wherein the dispensing orifice is coaxially aligned within the dispensing conduit.

2. A tap as claimed in claim 1 , further comprising a press button for moving the piston between the dispensing and sealing positions.

3. A tap as claimed in claim 2 , wherein, in the sealing position, the button is generally dome-shape.

4. A tap as claimed in claim 2 , wherein, in the sealing position, the button is generally flat.

5. A tap as claimed in claim 2 , wherein the button comprises a TPE material.

6. A tap as claimed in claim 1 , wherein the piston comprises a stem and a cylindrical sealing wall.

7. A tap as claimed in claim 6 , wherein
said one or more dispensing apertures comprises a plurality of dispensing apertures,
the piston further comprises a plurality of spokes, and
the stem is joined to the wall by the plurality of spokes, said plurality of spokes defining the plurality of dispensing apertures therebetween.

8. A tap as claimed in claim 1 , wherein the dispensing orifice is centrally positioned relative to the dispensing conduit.

9. A continuous flow press tap, comprising:
a body which is attached or attachable to a container, the body having a dispensing orifice,
a mobile piston movable within the body between a first position in which product is passable through the dispensing orifice and a second position in which the product is not passable through the dispensing orifice, and
a tubular terminal dispensing conduit extends beyond the dispensing orifice, the dispensing orifice having a first cross-sectional shape and the dispensing conduit having a second cross-sectional shape, the first and second shapes being different from each other,
wherein the dispensing orifice is coaxially aligned within the dispensing conduit.

10. A tap as claimed in claim 9 , wherein the first shape is selected from the group consisting of: circular, square, oval, ellipsoidal, triangular and polygonal.

11. A tap as claimed in claim 9 , wherein the second shape is selected from the group consisting of: circular, square, oval, ellipsoidal, triangular and polygonal.

12. A tap as claimed in claim 9 , wherein the first shape is generally ellipsoidal and the second shape is generally square.

13. A dispensing pack, comprising:
a container filled with a flowable product, and
a dispensing tap attached to the container for controlling flow of the flowable product out of the container, wherein the flowable product has a viscosity in the range 4.000-6.000 cps at 0.05 s 1 , the dispensing tap comprising:
a body which is attached to the container, the body having a dispensing orifice and a tubular terminal dispensing conduit, and
a piston movable within the body between a dispensing position in which the flowable product is passable through the dispensing orifice and a sealing position in which the flowable product is not passable through the dispensing orifice, wherein the piston comprises one or more dispensing apertures through which the flowable product is passable when the piston is in the dispensing position to reach the dispensing orifice,
wherein the dispensing conduit extends beyond the dispensing orifice, the dispensing orifice having a first cross-sectional shape and the dispensing conduit having a second cross-sectional shape, the first and second shapes being different from each other, and
wherein the dispensing orifice is coaxially aligned within the dispensing conduit.

14. A pack as claimed in claim 13 , wherein the flowable product is a laundry care product.

15. A dispenser, comprising:
a body which is attached or attachable to a container, the body comprising:
a dispensing orifice through which flowable product from the container is to be dispensed in use, and
a product tunnel through which the flowable product is passable to reach the dispensing orifice,

a mobile piston movable within the flowable product tunnel along a path having a piston movement axis between
a first position in which the flowable product is flowable through the dispensing orifice in a direction generally orthogonal to the piston movement axis, and
a second position in which the flowable product is not flowable through the dispensing orifice, and

a resilient push button for moving the piston from the second position to the first position, the button being biased to keep the piston in the second position and depressable to move the piston to the first position,
wherein the piston comprises one or more dispensing apertures through which the flowable product is passable when the piston is in the first position to reach the dispensing orifice,
wherein the dispenser further comprises a tubular terminal dispensing conduit that extends beyond the dispensing orifice, the dispensing orifice having a first cross-sectional shape and the dispensing conduit having a second cross-sectional shape, the first and second shapes being different from each other, and
wherein the dispensing orifice is coaxially aligned within the dispensing conduit.

16. A dispenser as claimed in claim 15 , wherein the product tunnel is generally cylindrical.

17. A dispenser as claimed in claim 15 , wherein the product tunnel is generally straight.

18. A dispenser as claimed in claim 15 , wherein the product tunnel has a generally circular section.

19. A dispenser as claimed in claim 15 , wherein the body is formed as a first part, the piston is formed as a second part and the button is formed as a third part.

20. A dispenser as claimed in claim 15 , wherein the body includes a base provided with a screw thread formation.

21. A dispenser as claimed in claim 15 , wherein the tubular terminal dispensing conduit is oriented approximately orthogonally to the product tunnel.
