Abstract

A dispensing apparatus (10) for dispensing a product from a container (12) includes: a product chamber within the container (12); a valve (14) adjacent to the product chamber; a hinge assembly secured to the opening of the container and to which is connected a nozzle assembly (20); and a lever (18) attached by means of the hinge assembly. The nozzle assembly (20) is rotatable between open and closed positions and includes an actuator portion provided with a cam surface (96, 98) which co-operates with a bearing portion (100) on the lever (18) such that, when the nozzle assembly (20) is in the open position, operation of the lever (18) causes movement of the actuator portion to open the valve (14) and permit flow of the product out of the container (12).

Claims

1. A dispensing apparatus for dispensing a product from a container, said apparatus comprising:

a container;

a product chamber within the container;

a tilt valve adjacent to the product chamber and having a valve stem provided with an external thread;

a hinge assembly attached to the container;

a lever hingedly attached to the hinge assembly and comprising a bearing portion; and

a nozzle assembly sealingly engageable with the hinge assembly and provided with an internal thread engaged with the external thread of the valve stem,

the nozzle assembly being rotatable relative to the hinge assembly and the lever between open and closed positions of said nozzle assembly and including an actuator portion provided with a surface which cooperates with the lever bearing portion such that in the open position of said nozzle assembly operation of the lever causes movement of the actuator portion to open the valve and permit flow of the product out of the apparatus.

2. A dispensing apparatus according to claim 1 further comprising means for urging said product from said product chamber.

3. A dispensing apparatus according to claim 1 wherein said actuator portion comprises a ring member and wherein said surface of said actuator portion is a cam surface and comprises at least one depression and at least one raised surface.

4. A dispensing apparatus according to claim 3 wherein said cam surface comprises two depressions arranged at opposite sides of said ring member and two raised surfaces arranged between the depressions at opposite sides of said ring member.

5. A dispensing apparatus according to claim 3 wherein said lever bearing portion is adapted to bear upon one of said depressions when said nozzle assembly is in the closed position and said lever bearing portion is adapted to bear upon one of said raised surfaces when the nozzle assembly is in the open position.

6. A dispensing apparatus according to claim 1 wherein said lever comprises two lever bearing portions arranged at opposite sides of said valve.

7. A dispensing apparatus according to claim 3 wherein said nozzle assembly is provided with one or more fin members adapted to hold the lever bearing portion against the cam surface.

8. A dispensing apparatus according to claim 7 wherein one of said one or more fin members is provided at each depression and at each raised surface of the cam surface, and wherein each one of said one or more fin members is spaced from the cam surface to allow the insertion of the lever bearing portion between said each one of said one or more fin members and the cam surface.

9. A dispensing apparatus according to claim 1 wherein said container is made from aluminum.
