Problems solved by technology

[0004] Furthermore, a common problem in the field of tooth whitening compositions is that common consumer formulations, such as adhesive dental strips, do not allow the user to apply the tooth whitening compound to hard-to-reach areas, such as between adjacent teeth. edge or surface

Embodiment Construction

[0020] The following description of preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its application or uses.

[0021] In one aspect, the present invention provides a single-use package for an oral care product comprising a plurality of chambers (e.g., two or three or more) and designed to The components within each chamber are kept separate and unreactive until the point of use. For example, the present invention provides a chemically stable structural package design that allows rapid mixing of components that are incompatible and therefore cannot be stored together for long periods of time just prior to use. The contents of the container are dispensed via an opening member, for example, through a spout or exit channel with a removable cap or stopper, or by breaking off the preferentially scored section of the container by the consumer or at the Dispensing opening that comes into play when the frangible seal is broken, all...

Abstract

The invention provides packages for storing and dispensing multi-component tooth whitening formulations, wherein the contents of the separate components are mixed just prior to use. Particular multi-component tooth whitening formulations using this principle and methods of use thereof are also provided.

Description

technical field [0001] The present invention relates to multi-component systems and devices for whitening teeth, for single use or multiple uses, which provide a stable, potent whitening agent activated just prior to use. Background technique [0002] It is often desirable to keep the various components of a formulation separate until the time of use of the formulation, for example, because the components, once combined, may not be stable enough for long-term storage. In such cases, it is desirable to be able to mix the various components of the formulation in a simple and efficient manner when the formulation is to be used, and it is also desirable to apply the resulting mixed formulation to hard-to-reach locations. [0003] An example of a composition where it may be desirable to keep the various components of the formulation separate is a tooth whitening composition comprising reactive ingredients such as peroxides, peroxyacids, persulfates or precursors thereof. For exa...
