Abstract

A process for making and packaging multi serving ice cream products using cryogenic hardening of ice cream in consumer containers before the containers are closed and labeled. A plastic tray container which is stable when disposed horizontally or vertically provides better processing and an improved package for both retailers and consumers.

Claims

1. A process for manufacturing and packaging a variety of ice cream products on a processing line comprising:

filling liquid raw materials into at least one mixing tank;

mixing said liquid raw materials in said at least one mixing tank;

cooling said liquid raw materials to a temperature near the freezing point of water whereby said liquid raw materials become ice cream;

providing a supply of open topped, low aspect ratio, unlabeled trays;

filling said trays with said ice cream;

hardening said ice cream filled trays in a cryogenic hardener wherein said ice cream is quickly hardened because of said low aspect ratio of said tray; and

, applying lids and labels bearing product identifying information to said hardened ice cream filled trays, thereby creating an ice cream product in a closed multiple serving container.

2. The process of claim 1, wherein said cryogenic hardener sprays cryogenic fluid on said open ice cream containing trays in said hardener.

3. The process of claim 2, wherein said cryogenic fluid starts as a liquid and becomes a gas during said hardening step.

4. The process of claim 3, wherein said gas circulates within said hardener cooling said ice cream.

5. The process of claim 1, wherein said lids are applied to said trays forming a closed container and labels are then applied to said container.

6. The process of claim 1, wherein printed matter is applied to said lid and said lid is then applied to said tray forming a closed container.

7. The process of claim 1, wherein said tray is rectangular.

8. The process of claim 1, wherein said tray is shallow and has an open top of large area.

9. The process of claim 8, wherein said tray is blow molded plastic.

10. The process of claim 9, wherein said tray is blow molded at the site of filling.

11. The process of claim 10, wherein said lid is blow molded at the site of filling.

12. An improved process for manufacturing and packaging ice cream products in a multiple serving shipping container comprising:

providing liquid raw materials in at least one mixing tank;

mixing said raw materials in said at least one mixing tank;

cooling said raw materials to a temperature near the freezing point of water until said raw materials become ice cream;

providing at least one open topped, low aspect ratio, unlabeled, multiple serving shipping container;

filling said shipping container with said ice cream;

hardening said ice cream in a cryogenic hardener wherein said ice cream is quickly hardened because of said low aspect ratio of said container;

applying a lid to said at least one shipping container thereby creating a closed container; and

applying a label to said closed container.

13. The process of claim 12, wherein a label is applied to said lid prior to applying said lid to said at least one shipping container.

14. The process of claim 12, wherein printed matter is applied to said lid prior to applying said lid to said at least one shipping container.

15. The process of claim 12, wherein a label is applied to said lid subsequent to applying said lid to said at least one shipping container.

16. The process of claim 12, wherein printed matter is applied to said lid subsequent to applying said lid to said at least one shipping container.

17. The process of claim 12, wherein said cryogenic hardener sprays cryogenic fluid on said ice cream containing shipping containers in said hardener.

18. The process of claim 17, wherein said cryogenic fluid starts as a liquid and becomes a gas during said hardening step.

19. The process of claim 18, wherein said gas circulates within said hardener cooling said ice cream.

20. The process of claim 12, wherein said shipping container is rectangular.

21. The process of claim 20, wherein said shipping container is shallow and said open top is the largest side of said rectangular shipping container.

22. The process of claim 12, wherein said shipping container is blow molded plastic.

23. The process of claim 22, wherein said shipping container is blow molded at the site of filling.
