Abstract

Disclosed is a container for a pump dispenser, the container including: a body defining a chamber for storing a product and defining an opening at a first end of the chamber through which the product is dispensable from the chamber; and a protrusion extending from the body into the chamber at a second end of the chamber opposite from the first end of the chamber, the protrusion having a sharp distal end in the chamber. Also disclosed is a refill container including a body enveloping a cavity storing an oral, personal or home care composition, wherein the composition includes water in an amount of less than 98% by weight, based on a total weight of the composition.

First claim

What is claimed is:

1. A pump dispenser system, the system comprising:
a body defining a chamber for storing a product and defining an opening at a first end of the chamber through which the product is dispensable from the chamber;
a protrusion extending from the body into the chamber at a second end of the chamber opposite from the first end of the chamber, the protrusion having a sharp distal end in the chamber, wherein the protrusion is unitary with the body; and a refill container comprising a refill container body enveloping a cavity storing a flowable oral, personal or home care composition, wherein the refill container body is water-soluble.

2. The system of claim 1 , wherein the protrusion extends from the body towards the opening.

3. The system of claim 1 , wherein a rim of the body defines the opening, wherein the rim lies in a first plane, and wherein the protrusion extends from the body in a direction normal to the first plane.

4. The system of claim 1 , wherein the opening extends along an axis central to the opening, the distal end of the protrusion lying upon the axis.

5. The system of claim 4 , wherein at least a portion of the protrusion extends along the axis.

6. The system of claim 5 , wherein both a proximal end and the distal end of the protrusion lie on the axis.

7. The system of claim 1 , wherein the protrusion tapers to a point or to an edge at the distal end of the protrusion.

8. The system of claim 1 , wherein two sides of the protrusion meet at an angle of less than 45 degrees at the distal end of the protrusion.

9. The system of claim 1 , wherein the protrusion is rotationally symmetric about an axis that extends from a proximal end of the protrusion to the distal end of the protrusion.

10. The system of claim 1 , comprising a closure movable relative to the body between a closed position at which the closure blocks the opening and an open position at which the opening is not blocked by the closure.

11. A pump dispenser comprising the system of claim 10 , wherein the closure comprises a pump for pumping the product from the chamber when the closure is at the closed position, and a dip tube with a lumen fluidly connected to the pump, the dip tube extending from the pump towards the second end of the chamber when the closure is at the closed position.

12. The pump dispenser of claim 11 , wherein the dip tube has a length sufficient that a distal end of the dip tube contacts the second end of the chamber at a position spaced from the protrusion.

13. The system of claim 1 , wherein the refill container body includes a wall portion which is piercable, and the body is free of any predefined openable passageways or predefined line of weakening, for placing the cavity in fluid communication with an exterior of the body; wherein the sharp distal end of the protrusion is for piercing the refill container body when the refill container is dropped into the chamber from and through the opening.

14. The system of claim 13 , wherein the system comprises a plurality of the refill containers.

15. The system of claim 13 , wherein the body is impermeable to the composition and wherein the refill container body is water-soluble such that the body is completely dissolvable in water at room temperature and atmospheric pressure within a time period of between 2 and 4 weeks.
