Abstract

Disclosed is a pump dispenser ( 100 ) comprising: a body ( 110 ) defining a hollow interior ( 113 ) and an opening ( 114 ) through which at least a portion of a refill cartridge ( 10 ) containing a flowable substance is receivable into the hollow interior ( 113 ); a lid ( 120 ); and a pump for pumping the flowable substance from the refill cartridge ( 10 ) when the portion of the refill cartridge ( 10 ) is in the hollow interior ( 113 ) and the lid ( 120 ) closes the opening ( 114 ). The lid ( 120 ) comprises a dip tube ( 126 ) with a lumen ( 127 ) fluidly connected to the pump, the dip tube ( 126 ) has a tapered end ( 126 A) located in the hollow interior ( 113 ) when the lid ( 120 ) closes the opening ( 114 ). At least one of the body ( 110 ) and the lid ( 120 ) has a grip on an exterior surface thereof for aiding relative movement of the body ( 110 ) and the lid ( 120 ) to access the hollow interior ( 113 ) when the lid ( 120 ) closes the opening ( 114 ). Also disclosed is a system comprising the pump dispenser ( 100 ) and the refill cartridge ( 10 ).

First claim

What is claimed is:

1. A system, comprising:
a pump dispenser comprising:
a body defining a hollow interior and an opening through which at least a portion of a refill cartridge containing a flowable substance is receivable into the hollow interior;
a lid for closing the opening of the body; and
a pump for pumping the flowable substance from the refill cartridge when the portion of the refill cartridge is in the hollow interior and the lid closes the opening of the body;
wherein the lid comprises a dip tube with a lumen fluidly connected to the pump, the dip tube having a tapered end that is located in the hollow interior of the body when the lid closes the opening of the body; and
the refill cartridge, wherein the refill cartridge comprises a container defining a chamber containing the flowable substance and having a rim defining an opening through which the flowable substance is dispensable from the chamber, and a seal attached to the container and closing the opening, wherein the seal is attached to the rim;
wherein the seal consists of one of a film, a membrane, and a foil, and wherein
the seal is puncturable by the tapered end of the dip tube when the portion of the refill cartridge is in the hollow interior and the lid is moved relative to the body to close the opening of the body.

2. The system of claim 1 , wherein the tapered end of the dip tube defines an opening into the lumen.

3. The system of claim 1 , wherein the dip tube is located at a center of the hollow interior of the body when the lid closes the opening of the body.

4. The system of claim 1 , wherein at least one of the body and the lid has a grip on an exterior surface thereof for aiding relative movement of the body and the lid to access the hollow interior when the lid closes the opening of the body.

5. The system of claim 4 , wherein each of the body and the lid has a grip on an exterior surface thereof.

6. The system of claim 4 , wherein the grip comprises a textured surface.

7. The system of claim 6 , wherein the textured surface comprises a plurality of ridges and/or depressions.

8. The system of claim 4 , wherein the grip is resilient.

9. The system of claim 4 , wherein the grip is elastomeric.

10. The system of claim 1 , wherein the lid comprises the pump.

11. The system of claim 1 , wherein the lid and the body are relatively rotatable to attach and detach the lid to and from the body.

12. The system of claim 11 , wherein the lid and the body have cooperating screw threads for retaining the lid relative to the body with the lid closing the opening of the body.

13. The system of claim 1 , wherein the opening of the body is circular.

14. The system of claim 1 , wherein the rim comprises a flange projecting in a direction away from the opening defined by the rim.

15. The system of claim 1 , wherein the flowable substance is a flowable home or personal care product, and wherein the personal care product is one or more of a liquid hand soap, a hand soap, a dentifrice, a hair care product, a body wash, a mouthwash, a skin cream, a deodorant composition, and an antiperspirant composition, or wherein the home care product is one or more of a laundry detergent, a dish washing detergent, a fabric softener, a fabric conditioner, a floor cleaner, and a surface cleaner.

16. The system of claim 1 , wherein a first cross-sectional area of the chamber at a point furthest from the opening defined by the rim is less than 60% of a parallel maximum cross-sectional area of the chamber, which is located between the opening and the point furthest from the opening.
