Abstract

A foamer for use in dispensing a liquid product with a foam consistency includes a top cap, a closure, a housing, an air-flow diaphragm, a mesh screen and a valve structure. The closure includes a portion which is received by the cap and these two (2) cooperate to define a foam outlet. The housing is assembled into the closure and the diaphragm is assembled into the housing. The mesh insert is positioned adjacent the foam outlet. The valve structure is provided in two (2) embodiments, one being a duckbill valve with a corresponding holder and the other being a metering valve with a corresponding holder.

Claims

1. A squeeze foamer for dispensing a liquid product and air mixture with a foam consistency, said squeeze foamer comprising:

a squeeze container;

a volume of liquid product received by said squeeze container;

a foamer assembled to said squeeze container and including;

a cap;

a closure having a portion received by said cap, said closure and said cap cooperating to define a foam outlet;

a housing assembled into said closure;

an air-flow diaphragm assembled into said housing, said air-flow diaphragm being constructed and arranged to permit the flow of mixing air and separately the flow of make-up air, said air-flow diaphragm including a body with an annular wall which defines an air-flow opening which extends radially through said annular wall;

a mesh screen positioned upstream of said foam outlet;

a liquid valve constructed and arranged for managing the flow of liquid product prior to said liquid product mixing with said mixing air, wherein said liquid valve includes a duckbill valve; and

a dip tube for routing air from said squeeze container into said foamer.

2. A foamer for use in dispensing as a foam a mixture of a liquid product and air, said foamer comprising:

a cap;

a closure having a portion received by said cap, said closure and said cap cooperating to define a foam outlet;

a housing assembled into said closure;

an air-flow diaphragm assembled into said housing, said air-flow diaphragm being constructed and arranged to permit the flow of mixing air and the flow of make-up air, said air-flow diaphragm including a body with an annular wall which defines an air-flow opening which extends radially through said annular wall;

a mesh positioned upstream of said foam outlet; and

a liquid valve constructed and arranged for managing the flow of liquid product prior to said liquid product mixing with said mixing air.

3. The foamer of claim 2 wherein said liquid valve includes a duckbill valve.

4. The foamer of claim 2 which further includes a liquid valve holder.

5. The foamer of claim 4 wherein said liquid valve holder is received by said housing.

6. The foamer of claim 4 wherein one portion of said diaphragm is cooperatively arranged with said liquid valve holder for managing air flow.

7. The foamer of claim 2 wherein a portion of said diaphragm is cooperatively arranged with said housing for managing air flow.

8. The foamer of claim 2 wherein one portion of said diaphragm is cooperatively arranged with said liquid valve holder for managing the flow of mixing air.

9. The foamer of claim 2 wherein one portion of said diaphragm is cooperatively arranged with said housing for managing the flow of make-up air.

10. The foamer of claim 2 wherein said housing defines a mix portion for air and product to mix before receipt by said mesh.

11. The foamer of claim 2 wherein said liquid valve is constructed and arranged as a metering valve and is received by a cooperating holder.

12. The foamer of claim 11 wherein said metering valve includes a deflectable flange which is movable in response to product flow.

13. The foamer of claim 2 wherein said diaphragm body is annular and defines an edge at one end of said annular wall and wherein said air-flow passage through said annular wall segments said edge.

14. A squeeze foamer for dispensing a liquid product and air mixture with a foam consistency, said squeeze foamer comprising:

a squeeze container;

a volume of liquid product received by said squeeze container;

a foamer assembled to said squeeze container and including;

a cap;

a closure having a portion received by said cap, said closure and said cap cooperating to define a foam outlet;

a housing assembled into said closure;

an air-flow diaphragm assembled into said housing, said air-flow diaphragm being constructed and arranged to permit the flow of mixing air and the flow of make-up air, said air-flow diaphragm including a body with a movable inner lip on an inner surface of said body for the control of mixing air and a movable outer lip on an outer surface of said body for the control of make-up air, said body including an annular wall which defines an air-flow opening which extends radially through said annular wall;

a mesh positioned upstream of said foam outlet; and

a liquid valve constructed and arranged for managing the flow of liquid product prior to said liquid product mixing with said mixing air; and

a dip tube for routing air from said squeeze container into said foamer.

15. The squeeze foamer of claim 14 wherein said liquid valve includes a duckbill valve.

16. The squeeze foamer of claim 14 which further includes a liquid valve holder.

17. The squeeze foamer of claim 16 wherein one portion of said diaphragm is cooperatively arranged with said liquid valve holder for managing air flow.

18. The squeeze foamer of claim 14 wherein a portion of said diaphragm is cooperatively arranged with said housing for managing air flow.

19. The squeeze foamer of claim 14 wherein said squeeze foamer is constructed and arranged as an inverted squeeze foamer when dispensing said product.

20. The squeeze foamer claim 14 wherein said air-flow opening providing an air-flow path from said dip tube to said inner lip.

21. A foamer for use in dispensing as a foam a mixture of a liquid product and air, said foamer comprising:

a cap;

a closure having a portion received by said cap, said closure and said cap cooperating to define a foam outlet;

a housing assembled into said closure;

an air-flow diaphragm assembled into said housing, said air-flow diaphragm being constructed and arranged to permit the flow of mixing air and the flow of make-up air, said air-flow diaphragm including a body with an annular wall which defines an air-flow passage radially through said annular wall;

a mesh positioned upstream of said foam outlet; and

a liquid valve constructed and arranged for managing the flow of liquid product prior to said liquid product mixing with said mixing air, wherein said liquid valve is constructed and arranged as a metering valve and is received by a cooperating holder.

22. The foamer of claim 21 wherein said metering valve includes a deflectable flange which is movable in response to product flow.
