Abstract

Packaging systems are configured for improving long-term stability of a composition. Packaging systems may include a packaging container defining an enclosed volume. The packaging system may additionally include a removable cover that enables the packaging container to be opened and closed such that the packaging container system includes a sealed or sealable volume to contain a main composition in fluid communication with a sacrificial composition. The main composition may include one or more volatile or gas-releasing materials and the sacrificial material may include a stabilizing component that replaces the at least one volatile or gas-releasing component within the main composition or displaces the at least one volatile or gas-releasing component within the enclosed volume. The sacrificial composition helps maintain stability of the main composition by accelerating equilibrium of vapors or gases within the headspace of the sealed interior volume.

First claim

What is claimed is:

1 . A packaging system, comprising:
a container and a removable cover defining at least one compartment configured to contain a dental appliance and a main composition including at least one volatile or gas-releasing component; and at least one region configured to contain a sacrificial composition separate from and in fluid communication with the main composition, the sacrificial composition including a stabilizing component that replaces the at least one volatile or gas-releasing component within the main composition or displaces the at least one volatile or gas-releasing component within the sealed interior volume.

2 . A packaging system as in claim 1 , wherein the at least one compartment is substantially impervious to the at least one volatile or gas-releasing component.

3 . A packaging system as in claim 1 , wherein the container comprises a laminate structure including at least one barrier layer substantially impervious to at least one of air, oxygen, other gases, moisture, or volatile material and at least one structural layer that provides strength and rigidity to the laminate structure.

4 . A packaging system as in claim 3 , wherein the laminate structure comprises at least one barrier material substantially impervious to oxygen molecules selected from the group of ethylene-vinyl alcohol copolymer (EVOH), propylene-vinyl alcohol copolymer (PVOH), polyvinylidene chloride (PVDC), polyamides, nylons, nitrile copolymers, polyacrylonitriles (PAN), polyethylene terephthalate (PET), resorcinol, ormocers, liquid crystal polymers (LCPs), aliphatic polyketones, plasma glass coatings, thermoset epoxy coatings, and nanocomposites.

5 . A packaging system as in claim 3 , wherein the laminate structure comprises at least one barrier material substantially impervious to water molecules selected from the group of cyclic olefin polymers (COPs), cyclic olefin copolymers (COCs), polychlorotrifluoroethylene (PCTFE), aluminum oxide coatings (AlOx), vinylidene chloride copolymers, high density polyethylene (HDPE), and polypropylene.

6 . A packaging system as in claim 3 , wherein the laminate structure comprises at least one structural polymer selected from the group of polyolefins, polyesters, polypropylene (PP), polyethylene (PE), polyvinylchloride (PVC), polyvinyldichloride (PVDC), ethylene-vinyl acetate copolymer (EVA), and glycol-modified polyethylene terephthalate (PETG).

7 . A packaging system as in claim 1 , wherein the removable cover comprises at least one of foil, paper, or laminate material.

8 . A packaging system as in claim 1 , wherein the at least one compartment has a shape that corresponds to a shape of the dental appliance.

9 . A packaging system as in claim 1 , further comprising the dental appliance and the main composition positioned within a first compartment of the container and the sacrificial composition positioned within a second compartment of the container in fluid communication with the first compartment.

10 . A packaging system as in claim 9 , wherein the sealed interior volume is less than about 500%, or less than about 300%, less than about 200%, of a combined volume of the main composition and the sacrificial composition.

11 . (canceled)

12 . (canceled)

13 . A packaging system as in claim 9 , wherein the dental appliance comprises a dental treatment tray.

14 . A packaging system as in claim 9 , wherein the at least one volatile or gas-releasing component in the main composition comprises a peroxide and wherein the stabilizing component in the sacrificial composition emits oxygen.

15 . A packaging system as in claim 9 , wherein the at least one volatile or gas-releasing component is selected from the group consisting of water and organic solvents.

16 . A packaging system as in claim 9 , wherein the main composition is an adhesive composition including at least one of a volatile solvent or volatile monomer, wherein the stabilizing component of the sacrificial composition comprises the volatile solvent or volatile monomer.

17 . A packaging system as in claim 9 , wherein the sacrificial composition has the same composition as the main composition.

18 . A packaging system as in claim 9 , wherein the stabilizing component of the sacrificial composition comprises the at least one volatile or gas-releasing component of the main composition.

19 . A packaging system as in claim 18 , wherein the sacrificial composition comprise a greater concentration or amount of the at least one volatile or gas-releasing material than the main composition.

20 . A packaging system as in claim 9 , wherein the at least one stabilizing component of the sacrificial composition has a vaporization rate greater than or equal to a vaporization rate of the at least one volatile or gas-releasing material of the main composition.

21 . A dental treatment system, comprising:
a sealed interior volume defined by a container and a removable cover; a dental composition positioned in the sealed interior volume, the dental composition comprising the at least one volatile or gas-releasing material; and a sacrificial composition separate from and in fluid communication with the dental composition and including a stabilizing component that replaces the at least one volatile or gas-releasing material within the main composition or displaces the at least one volatile or gas-releasing material within the sealed interior volume.

22 . A dental treatment system as in claim 21 , wherein the dental composition is a dental treatment composition or a dental adhesive composition.

23 . A dental treatment system as in claim 21 , further comprising a dental treatment tray having the dental composition disposed thereon, and wherein the dental composition comprises a dental bleaching composition comprising a peroxide.

24 . A dental treatment system as in claim 21 , wherein the sealed interior volume comprises a first compartment containing the dental composition and a second compartment containing the sacrificial composition, and wherein the fluid communication is established by at least one passageway between the first compartment and the second compartment.

25 . (canceled)

26 . A dental treatment system as in claim 21 , wherein the container comprises a laminate structure including at least one barrier layer substantially impervious to at least one of air, gases, moisture, or volatile material and at least one structural layer that provides strength and rigidity to the laminate structure, and wherein at least one of the container and the removable cover is substantially impervious to at least one of air, gases, moisture, or volatile material.

27 . (canceled)

28 . A dental bleaching system, comprising:
a packaging container and removable cover defining a sealed interior volume; a dental bleaching device disposed within the sealed interior volume and comprising:
a barrier layer configured for placement over at least a portion of a person's teeth; and
a dental bleaching composition disposed adjacent to the barrier layer and comprising a peroxide; and
a sacrificial composition separate from the dental bleaching device and disposed within the sealable interior volume, the sacrificial composition containing an oxygen-releasing material which emits oxygen within the sealable interior volume and reduces decomposition of the peroxide prior
