Abstract

Abstract A container of a food or beverage product, characterised in that it is constructed from a tubular wall portion open at both ends, the dimensions of the open ends being substantially the same as the transverse dimensions of the remainder of the tubular wall portion, that the tubular wall portion is of biaxially oriented thermoplastics material and is transparent, that the container further comprises end closures (30, 31) formed separately from the tubular wall portion but sealingly secured thereto to close its ends, and that a food or beverage product is hermetically sealed within the container and displayed through the tubular wall portion.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 102 words
A container of a food or beverage product, characterised in that it is constructed from a tubular wall portion open at both ends, the dimensions of the open ends being substantially the same as the transverse dimensions of the remainder of the tubular wall portion, that the tubular wall portion is of biaxially oriented thermoplastics material and is transparent, that the container further comprises end closures (30,31) formed separately from the tubular wall portion but sealingly secured thereto to close its ends, and that a food or beverage product is hermetically sealed within the container and displayed through the tubular wall portion.
Claim 2
Dependent Claim 102 words
A container of a food or beverage product, characterised in that it is constructed from a tubular wall portion open at both ends, the dimensions of the open ends being substantially the same as the transverse dimensions of the remainder of the tubular wall portion, that the tubular wall portion is of biaxially oriented thermoplastics material and is transparent, that the container further comprises end closures (30,31) formed separately from the tubular wall portion but sealingly secured thereto to close its ends, and that a food or beverage product is hermetically sealed within the container and displayed through the tubular wall portion.
Claim 3
Dependent Claim 48 words
A container as claimed in claim 1, characterised in that it is heat processable, the tubular wall has been subjected to a heat treatment whilst restrained against excessive dimensional change, the heat treatment having been such as to give the thermoplastics material dimensional stability at heat processing temperatures.
Claim 4
Dependent Claim 18 words
A container as claimed in claim 1 or claim 2, characterised in that the thermoplastics material is PET.
Claim 5
Dependent Claim 30 words
A container as claimed in any one of claims 1 to 3, characterised in that the end closures (30,31) are of metal and are crimped on to the tubular wall.
