Abstract

A system for dispensing a personal care fluid, such as a hand soap or the like. The system includes a dispenser and a refill cartridge. The dispenser includes a dispenser body having a refill cavity and a dispenser lid configured to be coupled to the dispenser body. There may be a pump sub-system mounted to the dispenser lid, or alternatively the personal care fluid may be dispensed by squeezing the dispenser and refill cartridge. The refill cartridge is configured for slidable insertion into and removal from the refill cavity of the dispenser body. The personal care fluid system is designed so that a user can readily and easily change out/replace the refill cartridge for use with a common dispenser, dispenser lid, and pump sub-system.

First claim

What is claimed is:

1. A system for dispensing a personal care fluid, the system comprising:
a dispenser comprising:
a dispenser body comprising a refill cavity having a top end;
a dispenser lid;
a pump sub-system mounted to the dispenser lid, the pump sub-system comprising a first dip tube, a dispensing orifice, and a pump;

a refill cartridge configured for slidable insertion and removal from the refill cavity via the top end of the refill cavity, the refill cartridge comprising:
a cartridge body comprising a fluid cavity, a top cartridge body end of the cartridge body comprising a rim defining an opening open to the fluid cavity;
a store of the personal care fluid in the fluid cavity;
a second dip tube extending into the store of the personal care fluid; and
a cartridge lid attached to rim to seal the opening, wherein the cartridge lid is a puncturable film;

the dispenser lid configured to be alterable between: (1) a first state in which the top end of the refill cavity is open so that the refill cartridge can be slid into the refill cavity; and (2) a second state in which the dispenser lid is coupled to the dispenser body to enclose the top end of the refill cavity and the second dip tube is operably mated with the first dip tube so that the store of the personal care fluid can be dispensed from the dispensing orifice upon actuation of the pump;
wherein when the dispenser lid is in the second state, the first dip tube penetrates the puncturable film;
wherein the dispenser body comprises one or more protuberances extending inward from an inner surface of the dispenser body that defines the refill cavity, the protuberances being separated from the top end of the dispenser body; and
wherein the cartridge body comprises one or more depressions that receive the one or more protuberances when the refill cartridge is positioned within the refill cavity, wherein the cartridge body comprises one or more shoulders; and wherein the one or more protuberances of the dispenser body contact the one or more shoulders of the cartridge body to support the refill cartridge, and wherein the refill cartridge is supported in a suspended manner so that a space exists below a lowermost surface of the refill cartridge.

2. The system according to claim 1 wherein the dispenser body is formed of a transparent material.

3. The system according to claim 1 wherein the refill cartridge and/or the dispenser body is configured so that the refill cartridge is non-rotatable relative to the dispenser body when positioned within the refill cavity.

4. The system according to claim 1 wherein:
the dispenser lid comprises one or more retaining elements; and
wherein when the refill cartridge is positioned within the refill cavity and the dispenser lid is in the second state, a portion of the cartridge body is positioned between and contacted by the one or more protuberances of the dispenser body and the one or more retaining elements of the dispenser lid to axially retain the refill cartridge relative to the dispenser.

5. The system according to claim 1 wherein when the dispenser lid is in the second state, a distal section of the first dip tube is disposed within a receiving section of the second dip tube.

6. The system according to claim 5 wherein the second dip tube further comprises a delivery section extending downward from the receiving section and terminating in a fluid inlet orifice; and wherein the receiving section defines a passageway having a first transverse cross-sectional area and the delivery section defines a passageway having a second transverse cross-sectional area, the first transverse cross-sectional area being greater than the second transverse cross-sectional area.

7. The system according to claim 6 wherein the refill cartridge further comprises a basket extending upward from the receiving section of the second dip tube, the basket configured to align and guide the first dip tube with the second dip tube as the dispenser lid is being altered from the first state into the second state, wherein the basket comprises a basket cavity and one or more vent passageways extending from the basket cavity to the fluid cavity.

8. The system according to claim 7 wherein the basket comprises an entry section and an alignment section, the alignment section located between the entry section of the basket and the second dip tube; and wherein a portion of the basket cavity defined by the alignment section has a transverse cross-sectional area that decreases with distance from the entry section in a tapered manner.

9. The system according to claim 7 wherein the pump sub-system comprises a dosage housing comprising a dosage chamber, the first dip tube extending downward from the dosage housing; and wherein the dosage housing nests within the basket when the dispenser lid is in the second state.

10. The system according to claim 1 further comprising:
the dispenser body comprising one or more coupling elements; and
the dispenser lid comprising one or more coupling elements configured to mate with the one or more coupling elements of the dispenser body and retain the dispenser lid in the second state.

11. The system according to claim 10 wherein the one or more coupling elements of the dispenser body or the one or more coupling elements of the dispenser lid comprise ramped surfaces and the other one of the one or more coupling elements of the dispenser body or the one or more coupling elements of the dispenser lid comprise follower surfaces; and wherein upon the follower surfaces engaging the ramp surfaces and the dispenser body and dispenser lid are rotated relative to one another in a first rotational direction, the dispenser lid and the dispenser body are axially drawn together and the second state is achieved.

12. The system according to claim 10 wherein, in the second state, interaction between the one or more coupling elements of the dispenser body or the one or more coupling elements of the dispenser lid prevent the dispenser lid from being axially translated relative to the dispenser body without the dispenser body and dispenser lid being rotated relative to one another in a second rotational direction.

13. The system according to claim 1 further comprising:
the dispenser body comprising one or more rotational alignment elements;
the dispenser lid comprising one or more rotational alignment elements;
the one or more rotational alignment elements of the dispenser body and/or the dispenser lid are configured to prohibit relative rotation between the dispenser lid and the dispenser body in a first rotational direction once a desired relative rotational orientation is achieved between the dispenser lid and the dispenser body.

14. The system according to claim 1 wherein the personal care fluid is a liquid soap.

15. A refill cartridge containing a personal care fluid for a dispensing system, the refill cartridge comprising:
a cartridge body comprising a fluid cavity, an upper neck portion and a lower reservoir portion, the upper neck portion comprising an upper edge defining an opening into the fluid cavity and at least one downwardly facing shoulder, the cartridge body extending along a cartridge axis, the lower reservoir portion having an increased diameter relative to the upper neck portion, the lower reservoir portion comprising one or more depressions formed into an outer surface of the cartridge body;
a store of the personal care fluid in the fluid cavity; and
a fluid delivery component disposed within the fluid cavity, the fluid delivery component comprising:
a basket comprising a basket cavity having an open top e
