Abstract

A coated packaging article may include a packaging article and a coating. The packaging article may include a body having an interior surface, and the coating may be disposed over at least one portion of the interior surface of the body. The coating may include an edible oil and a surfactant. The coating may be in a liquid state on the interior surface inside the packaging article. The coating may be in direct contact with the at least one portion of the interior surface of the body.

First claim

What is claimed is:

1 . A coated packaging article for an oral, personal, or home care composition, comprising:
a packaging article comprising a body having an interior surface; and a coating disposed over at least one portion of the interior surface of the body, the coating comprising an edible oil and a surfactant; wherein the coating is in a liquid state on the interior surface inside the packaging article; wherein the surfactant comprises at least one of a betaine type surfactant, a glucoside surfactant, or a glutamate surfactant; wherein the edible oil comprises at least one of flaxseed oil, hemp seed oil, or chia seed oil; and wherein a weight ratio of the edible oil to the surfactant ranges from about 20:1 to about 5:1.

2 . The coated packaging article according to claim 1 , wherein the surfactant comprises a natural surfactant.

3 . The coated packaging article according to claim 1 , wherein the surfactant comprises a C10-C20 long-chain component.

4 . The coated packaging article according to claim 1 , wherein the edible oil comprises a C10-C22 long-chain component.

5 . The coated packaging article according to claim 1 , wherein the edible oil is present in the coating in an amount ranging from 70 wt. % to about 99 wt. %.

6 . The coated packaging article according to claim 1 , wherein a thickness of the coating ranges from about 10 μm to about 300 μm.

7 . The coated packaging article according to claim 1 , wherein the coating is configured to maintain the liquid state on the interior surface inside the packaging article for at least 30 days.

8 . The coated packaging article according to claim 1 , wherein the coating is in direct contact with the at least one portion of the interior surface of the body.

9 . The coated packaging article according to claim 1 , wherein the coating forms a surface facing an interior of the packaging article, and wherein the surface formed by the coating is substantially smooth.

10 . The coated packaging article according to claim 1 , wherein the body comprises a fibrous material.

11 . The coated packaging article according to claim 10 , wherein the interior surface of the body is defined at least in part by the fibrous material.

12 . The coated packaging article according to claim 10 , wherein the body further comprises a lining disposed over the fibrous material, wherein the interior surface of the body is defined at least in part by the lining, and wherein the lining comprises at least one of polyethylene (PE), polyethylene terephthalate (PET), paperboard, cardboard, or fiberboard.

13 . The coated packaging article according to claim 1 , wherein the body comprises a plastic tube, and wherein the interior surface of the body is defined at least in part by the plastic tube.

14 . The coated packaging article according to claim 13 , wherein the plastic tube comprises at least one of polypropylene (PP), polyethylene (PE), or polyethylene terephthalate (PET).

15 . A packaged substance, comprising:
a toothpaste; and a coated packaging comprising:
a packaging article comprising a body having an interior surface; and
a coating disposed over at least one portion of the interior surface of the body, the coating comprising:
an edible oil comprising at least one of flaxseed oil, hemp seed oil, or chia seed oil; and
a surfactant comprising a C10-C20 long-chain component;

wherein the toothpaste is received in the packaging article;
the coating is in a liquid state on the interior surface inside the packaging article, the coating disposed between the interior surface of the body of the packaging article and the toothpaste.

16 . A method of dispensing a packaged substance according to claim 15 , the method comprising dispensing a portion of the substance out of the packaging article, wherein a portion of the coating is dispersed out of the packaging article along with the substance.

17 . The coated packaging article according to claim 15 , wherein the surfactant comprises at least one of a betaine type surfactant, a glucoside surfactant, or a glutamate surfactant.

18 . The coated packaging article according to claim 15 , wherein the edible oil comprises at least one of flaxseed oil, hemp seed oil, or chia seed oil.

19 . The coated packaging article according to claim 15 , wherein a weight ratio of the edible oil to the surfactant ranges from about 20:1 to about 5:1.
