Abstract
The present invention relates to multi-compartment devices having a pre-applied dispensing element. The device is adapted for dispensing multi-component compositions that are kept separate prior to use. Supplying a pre-applied dispensing element facilitates and simplifies the dispensing operation during use and reduces the chance of misuse due to improper application of the mixing element, loss and/or damage of the component.

- a housing having at least two chambers, each of said chambers having an outlet and an inlet with full fluid communication between the inlet and the outlet;
- at least one sealing system for substantially sealing the outlets of the chambers during storage, and at least one formation disposed in the chambers for effecting the unsealing of the outlets of the chambers;
- and
- a dispensing tip attached to the housing about the outlets of the chambers, said tip comprising a generally axial bore, an inlet and an outlet;
- wherein at least a portion of said sealing system is disposed within said bore.
A multi-chambered device for storing and dispensing the material components of an admixture, comprising:
- a housing having at least two chambers each having an outlet and an inlet with full fluid communication between the inlet and the outlet;
- a dispensing tip adapted for attaching to the housing about the outlets of the chambers, said tip comprising a generally axial bore, an inlet and an outlet;
- and
- a switching assembly disposed within the bore of the tip, said switching assembly having at least one aperture, said aperture is at an open or closed position by rotating the switching assembly.
A multi-chambered device for storing and dispensing the material components of an admixture, comprising:
- a housing having at least two chambers each having an outlet and an outlet with full fluid communication between the inlet and the outlet;
- and
- a rotatable dispensing tip adapted for attaching to the housing about the outlets of the chambers, said tip comprising a generally axial bore, an inlet and an outlet;
- wherein the device is in its closed position when the tip is turned toward one direction, and the device is in its open position when the tip is turned toward the other direction.
