Abstract

Food holding system, liner thereof, and associated methods. A food tray receiver liner is configured to be installed in a food tray receiver. The liner is configured to collect food that may fall into the food tray receiver. Desirably, the liner obstructs food from passing between the liner and side walls of the food tray receiver.

Claims (44)

1. A method of using a liner with a food tray receiver of a food holding apparatus, the food tray receiver having a floor and a plurality of food tray receiver side walls defining a food tray receiver cavity for receiving one or more trays of food, the food tray receiver having a top opening defining a top of the food tray receiver cavity and in which the one or more trays of food are receivable for reception in the food tray receiver cavity, the method comprising:

placing the liner in the food tray receiver cavity, the liner comprising:

a flexible body sized and shaped to be inserted into the food tray receiver cavity of the food tray receiver, the flexible body having a base and a plurality of body side walls extending generally upward from the base, the flexible body having a food receiving cavity defined by the base and the plurality of side walls, the food receiving cavity having an open top configured to receive food when the flexible body is disposed in the food tray receiver and food falls toward the flexible body; and

forming a seal between the side walls of the flexible body and the food tray receiver side walls to generally prevent food from moving between the food receiver side walls and the body side walls, the seal being formed in the food tray receiver cavity at an elevation below the top opening of the food tray receiver.

2. The method of claim 1 , wherein forming the seal includes moving the body side walls into engagement with the food tray receiver side walls.

3. The method of claim 2 , wherein moving the body side walls includes deforming the base of the flexible body with a raised portion of the floor of the food tray receiver.

4. The method of claim 3 , wherein deforming the base of the flexible body includes the base of the flexible body sagging downward into a recess of the floor of the food tray receiver.

5. The method of claim 4 , wherein the recess extends around a perimeter of the floor of the food tray receiver.

6. The method of claim 4 , wherein the recess extends around the raised portion of the floor of the food tray receiver.

7. The method of claim 2 , wherein moving the body side walls includes deforming the flexible body outward by heating the flexible body.

8. The method of claim 1 , wherein each body side wall tapers outward as said body side wall extends generally upward from the base.

9. The method of claim 1 , wherein forming the seal includes forming a complete perimeter seal around the food tray receiver cavity with the liner.

10. The method of claim 1 , wherein the flexible body has a length and a width, the length measured between upper edges of two opposing side walls of the plurality of side walls and the width measured between upper edges of two other opposing side walls of the plurality of side walls, wherein the length and the width increase during said forming the seal.

11. The method of claim 1 , wherein forming the seal includes moving the body side walls outward into engagement with the food tray receiver side walls.

12. The method of claim 1 , wherein said forming the seal includes moving a liner side wall face of one of the side walls of the flexible body into engagement with an upstanding receiver side wall face of one of the food tray receiver side walls.

13. The method of claim 1 , wherein the flexible body is resiliently deformable.

14. The method of claim 1 , wherein the flexible body comprises silicone.

15. The method of claim 1 , further comprising placing, after said forming the seal, a tray of food in the food tray receiver cavity.

16. A method of using a liner with a food tray receiver of a food holding apparatus, the method comprising:

inserting the liner into a food tray receiver cavity of the food tray receiver, the food tray receiver cavity sized and shaped to receive one or more trays of food; and

conforming the liner, after said inserting the liner, to the food tray receiver to form a seal between the liner and the food tray receiver to block food from moving between the liner and the food tray receiver, the seal being formed in the food tray receiver cavity.

17. The method of claim 16 , wherein the liner forms a complete perimeter seal around the food tray receiver cavity.

18. The method of claim 16 , wherein the liner has a first configuration when inserted into the food tray receiver, and wherein the liner has a second configuration different from the first configuration after said conforming the liner to the food tray receiver.

19. The method of claim 16 , wherein conforming the liner includes deforming the liner by heating the liner.

20. The method of claim 19 , wherein heating the liner includes heating the liner with an electrical resistance heating element of the food tray receiver.

21. The method of claim 16 , wherein conforming the liner includes deforming a base of the liner with a floor of the food tray receiver.

22. The method of claim 21 , wherein said inserting the liner includes resting the liner on the floor of the food tray receiver.

23. The method of claim 16 , wherein conforming the liner includes moving a plurality of side walls of the liner into engagement with the food tray receiver.

24. The method of claim 16 , wherein conforming the liner includes moving a rim of the liner outward into engagement with the food tray receiver.

25. The method of claim 16 , wherein the seal is at least partially formed when the liner is at rest in the food tray receiver after said inserting the liner.

26. The method of claim 16 , wherein the liner includes a liner side wall having a liner side wall face and the food tray receiver includes an upstanding receiver side wall having an upstanding receiver side wall face, and wherein said conforming the liner includes moving the liner side wall face into engagement with the upstanding receiver side wall face.

27. The method of claim 16 , wherein the seal is located at an elevation below a midpoint of a height of the food tray receiver cavity.

28. The method of claim 16 , wherein the liner is flexible.

29. The method of claim 16 , wherein the liner is resiliently deformable.

30. The method of claim 16 , wherein the liner comprises silicone.

31. The method of claim 16 , further comprising placing, after said conforming the liner, a tray of food in the food tray receiver cavity.

32. A method of using a liner with a food tray receiver of a food holding apparatus, the food tray receiver having a floor and a plurality of food tray receiver side walls defining a food tray receiver cavity for receiving one or more trays of food, the method comprising:

placing the liner in the food tray receiver cavity, the liner comprising:

a flexible body sized and shaped to be inserted into the food tray receiver cavity of the food tray receiver, the flexible body having a base and a plurality of body side walls extending generally upward from the base, the flexible body having a food receiving cavity defined by the base and the plurality of side walls, the food receiving cavity having an open top configured to receive food when the flexible body is disposed in the food tray receiver and food falls toward the flexible body; and

forming a seal between the side walls of the flexible body and the food tray receiver side walls to generally prevent food from moving between the food receiver side walls and the body side walls, said forming the seal including moving the body side walls into engagement with the food tray receiver side walls, said moving the body side walls including deforming the base of the flexible body with a raised portion of the floor of the food tray receiver.

33. The method of claim 32 , wherein deforming the base of the flexible body includes the base of the flexible body sagging downward into a recess of the floor of the food tray receiver.

34. The method of claim 33 , wherein the recess extends around a perimeter of the floor of the food tray receiver.

35. The method of claim 33 , wherein the recess extends around the raised portion of the floor of the food tray receiver.

36. The method of claim 32 , further comprising placing, after said forming the seal, a tray of food in the food tray receiver cavity.
