Abstract

A container for receiving a food product is formed from a shaped blank of paper, paperboard, cardboard or a similar material. A hinge arrangement comprising at least two and preferably three parts is provided between one of the side walls and one of the end walls to allow the partially formed container to be moved easily between a flat configuration suitable for transportation or storage and an erect configuration for receiving a food product. In the erect configuration one part of the hinge arrangement is sandwiched between another part of hinge arrangement and the end wail. In the flat configuration these two parts of the hinge arrangement lie in substantially the same plane. An integral lid may be provided.

Claims

1-20. -20. (canceled)

21. A partially assembled container for receiving a food product and formed from a partially fastened folded blank, the container having triangular side walls and substantially rectangular end walls to enable the formation of a generally triangular prism-shaped container with an opening for receiving the food product, wherein hinge means comprising a first hinge part hingedly connected to a second hinge part are provided between a first side wall and a first end wall, and wherein the partially assembled container is formed by fixing one of said first and second hinge parts to said first side wall or to said first end wall and is moveable between a substantially flat position, in which the first and second hinge parts lie in substantially the same plane, for storage and transportation and a substantially erect position, in which the first and second hinge parts overlie one another, for receiving a food product.

22. The partially assembled container as claimed in claim 21, wherein the first hinge part is hingedly connected to said first side wall, and the second hinge part is rigidly connected to said first end wall.

23. The partially assembled container as claimed in claim 22, wherein the first hinge part and said first end wall sandwich the second hinge part when the container is in a substantially erect condition.

24. A partially assembled container as claimed in claim 23, wherein the hinge means additionally comprises a third hinge part hingedly connected to the second hinge part and rigidly connected to the said first end wall such that the said first end wall is sandwiched by the second and third hinge parts.

25. The partially assembled container as claimed in claim 21, wherein the hinge means additionally comprises a third hinge part hingedly connected to the second hinge part and rigidly connected to the said first end wall such that the said first end wall is sandwiched by the second and third hinge parts.

26. The partially assembled container as claimed in claim 25, wherein the third hinge part and the surface of the first end wall to which it is connected are substantially congruent.

27. The partially assembled container as claimed in claim 21, wherein the hinge means additionally comprises a third hinge part hingedly connected to the second hinge part and rigidly connected to the said first end wall such that the said third hinge part is sandwiched by the first end wall and the second hinge part.

28. The partially assembled container as claimed in claim 21, wherein the hinge means additionally comprises a third hinge part hingedly connected to the second hinge part and rigidly connected to the said first end wall, and the first hinge part is securely fastened to said first side wall when the container is in its substantially erect position.

29. The partially assembled container as claimed in claim 21, wherein the hinge means are integral with the said first side wall.

30. The partially assembled container as claimed in claim 21, wherein an integrally formed lid is provided for covering the opening in the container when it is in its erect condition.

31. A blank for forming a container for receiving a food product, the blank having first and second triangular side walls and first and second substantially rectangular end walls to enable the formation a generally triangular prism-shaped container with an opening for receiving the food product, the blank further comprising hinge means, the hinge means comprising a first hinge part hingedly connected to a second hinge part and arranged between a first side wall and a first end wall wherein the blank enables a partially assembled container to be formed by folding the blank into a substantially flat position in which the first and second hinge parts lie in substantially the same plane and fixing one of said first and second hinge parts to said first side wall or to said first end wall, and to be moved between a substantially flat position for storage and transportation and a substantially erect position, in which the first and second hinge parts overlie one another, for receiving a food product.

32. The blank as claimed in claim 31, wherein the first hinge part is hingedly connected to said first side wall.

33. The blank as claimed in claim 31, wherein the hinge means additionally comprises a third hinge part hingedly connected to the second hinge part.

34. The blank as claimed in claim 33, wherein the third hinge part and the first end wall are substantially congruent.

35. The blank as claimed in claim 34, wherein the hinge means are integral with the first side wall.

36. The blank as claimed in claim 31, wherein an integrally formed lid is provided for covering the opening in the container when it is in its erect condition.

37. A method of forming a container from a blank according to claim 31, the method comprising the following steps:

1) folding the hinge means to overlie at least the first side wall;

2) bringing the first end wall into abutment with the second end wall by folding the second side wall about a central fold line thereof;

3) folding the blank about the connection between the second end wall and the first side wall to bring part of the first end wall into abutment with the exposed surface of the second hinge part;

4) gluing the abutting surfaces of the second hinge part and the first end wall together to form a permanent join; and

5) pulling the first and second side walls in opposite directions such that the container naturally opens out into an erect state.

38. A method of forming a container from a blank according to claim 33, the method comprising the following steps:

1) folding the hinge means to overlie the first side wall and the second end wall;

2) bringing the first end wall into abutment with the exposed surfaces of the third hinge part by folding the second side wall about a central fold line thereof;

3) gluing the abutting surfaces of the third hinge part and the first end wall together to form a permanent join;

4) folding the blank about the connection between the third hinge part and the second hinge part to bring part of the first end wall into abutment with the exposed surface of the second hinge part;

5) gluing the abutting surfaces of the second hinge part and the first end wall together to form a permanent join and thereby sandwich part of the first end wall between the third hinge part and the second hinge part; and

6) pulling the first and second side walls in opposite directions, such that the container naturally opens out into an erect state.

39. A method of forming a container from a blank according to claim 33, the method comprising the following steps:

1) fastening the third hinge part to the inner surface of the first end wall and folding the partially fastened container into a substantially flat configuration;

2) storing the partially fastened container and transporting it to a food producer;

3) opening the partially fastened container; and

4) erecting the container by bringing the first and second hinge parts into abutment and fastening the hinge means in the abutting configuration ready for receipt of a food product.
