Abstract
Abstract A jacket of heat insulating material, such as expanded polystyrene foam, for use with drinking utensils, such as glasses, cans, bottles or the like, of various shapes and sizes. The jacket is composed of a bottom having the shape of a regular polygon with a plurality of side wall elements, each pivotally connected to a straight edge of the polygonal bottom by a flexible membrane capable of folding along anyone of several fold lines parallel to the associated bottom edge, each side wall element being independent from and overlapping an adjacent side wall element. Thus, the side wall elements can fit drinking utensils of various sizes and shapes and there is no solution of continuity at the surface of the jacket.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
145 words
A jacket for use with drinking utensils and made of heat insulating material comprising a bottom having the shape of a regular polygon, a side wall composed of a plurality of separate side wall elements, each independently hinged to a straight side edge of said polygonal bottom, each side wall element of an elongated shape, said side wall elements capable of taking an inclined as well as a perpendicular position with respect to the bottom to substantially fit tapered as well as non-tapered drinking utensils, each side wall element further being of generally rectangular shape and formed of two longitudinal sections disposed side by side and offset one with respect to the other across their thickness, one section only being hinged to the bottom and the other section laterally extending from said hinged section, said side wall elements overlapping each other in their upright condition.
Claim 2
Dependent Claim
145 words
A jacket for use with drinking utensils and made of heat insulating material comprising a bottom having the shape of a regular polygon, a side wall composed of a plurality of separate side wall elements, each independently hinged to a straight side edge of said polygonal bottom, each side wall element of an elongated shape, said side wall elements capable of taking an inclined as well as a perpendicular position with respect to the bottom to substantially fit tapered as well as non-tapered drinking utensils, each side wall element further being of generally rectangular shape and formed of two longitudinal sections disposed side by side and offset one with respect to the other across their thickness, one section only being hinged to the bottom and the other section laterally extending from said hinged section, said side wall elements overlapping each other in their upright condition.
Claim 3
Dependent Claim
16 words
A jacket as claimed in claim 1, wherein the outer section is hinged to said bottom.
Claim 4
Dependent Claim
48 words
A jacket as claimed in claim 2, wherein the inner corner of the inner section is bevelled, so as to separate said inner section from an adjacent outer section in flattened condition of the jacket with the side wall elements lying in substantially flat plane containing said bottom.
Claim 5
Dependent Claim
53 words
A jacket as claimed in claim 1, wherein said side wall elements are hinged to the respective straight side edges of said bottom by means of a hinge membrane, which is thin and flexible and capable of folding along different fold lines parallel to the associated bottom side edge and increasingly spaced therefrom.
Claim 6
Dependent Claim
49 words
A jacket as claimed in claim 4, wherein said hinge membrane is thinner than said bottom and said side wall elements and is provided at its inside surface with a plurality of grooves parallel to said bottom side edge and spaced from one another end defining said fold lines.
Claim 7
Dependent Claim
39 words
A jacket as claimed in claim 1, wherein the upper and lower transverse edges of said inner section are rounded and said hinge membrane is attached to the lower edge of the outer section of the side wall element.
Claim 8
Dependent Claim
16 words
A jacket as claimed in claim 2, made of a single molded piece of plastic foam.
Claim 9
Dependent Claim
57 words
A jacket as claimed in claim 1, wherein said side wall elements are provided each with at least one groove adapted to register with the groove of adjacent side wall elements and an elastic band fitting within said groove and surrounding the jacket to press said side wall elements radially inwardly towards the center of the jacket.
Claim 10
Dependent Claim
57 words
A jacket as claimed in claim 2, wherein said side wall elements are provided each with at least one groove adapted to register with the groove of adjacent side wall elements and an elastic band fitting within said groove and surrounding the jacket to press said side wall elements radially inwardly towards the center of the jacket.
