Packaging and method for single serve beverage product
A packaging method and packaging material are disclosed. In accordance with one aspect, a method for forming, filling, sealing and flash freezing a liquid extract or concentrate in a continuous ribbon format is described. The packaging material uses a continuous ribbon of a cold-formed foil base with multiple pockets arrayed in a pattern and a heat-sealed foil cover. Following sealing, the continuously formed strip of product is passed through a freezing medium, optionally perforated alongside the pockets to facilitate separation of individual pockets from a sheet, and then cut to size for convenient and space efficient final packaging, storage and transportation.
1. A package for delivering frozen liquid content comprising:
a foil base comprising one or more pockets within a planar surface;
a solid frozen liquid content disposed in each pocket; and
a foil cover attached to the planar surface of the foil base, wherein the pockets and the foil cover define one or more sealed cavities for containing the solid frozen liquid content, wherein there is a headspace disposed between the solid frozen content and the foil cover, wherein the headspace comprises at least one of an inert gas and a reduced reactivity gas in place of atmospheric air.
2. The package of claim 1 , wherein the package comprises a gas impermeable material configured to preserve freshness and aroma of the solid frozen liquid content.
3. The package of claim 1 , wherein the solid frozen liquid content is selected from the group consisting of:
a frozen coffee extract;
a frozen tea extract;
a frozen lemonade concentrate;
a frozen vegetable concentrate;
a frozen broth;
a frozen liquid dairy product;
a frozen alcohol product;
a frozen concentrated soup;
a frozen syrup;
a frozen fruit concentrate, and any combination thereof.
4. The package of claim 1 , wherein the package is filterless.
5. The package of claim 1 , wherein the solid frozen liquid content of each pocket is provided in a controlled portion arrangement.
6. The package of claim 5 , wherein the controlled portion arrangement comprises a single-serving sized format.
7. The package of claim 1 , wherein the package, including the foil base and the foil cover form a gas impermeable package.
8. The package of claim 1 , wherein the foil base and the foil cover are joined via heat sealing.
9. The package of claim 1 , wherein the foil base and the foil cover are joined via ultrasonic welding.
10. The package of claim 1 , wherein the foil base and the foil cover are joined via adhesive.
11. The package of claim 1 , further comprising a coating on at least a portion of the pocket, wherein the coating reduces adhesion of the solid frozen liquid content to the package relative to uncoated surfaces.
12. The package of claim 1 , wherein the solid frozen liquid content comprises at least one of a frozen liquid extract and a frozen liquid concentrate.
13. The package of claim 1 , wherein the pocket further comprises tapered planar sidewalls and a planar bottom.
14. The package of claim 1 , wherein the pocket further comprises a generally concave shape.
15. The package of claim 2 , wherein the gas impermeable material comprises aluminum.
