First Claim
1. A double-wall cup comprising:
- an inner wall and an outer wall,an upper cup opening and a lower cup bottom,at least the outer wall is essentially formed from paper or cardboard,the inner wall is formed by an inner cup, which is inserted into an outer cup providing the outer wall,the inner cup being detachably attached in the outer cup,the inner cup is formed from an at least fluid-tight plastic material,the inner cup terminates with its lower end spaced apart from a lower end of the outer cup such that an accommodation space exists between the lower end of the inner cup and the lower end of the outer cup and the lower end of the inner cup does not contact the lower end of the outer cup,a lower cup section of the outer cup is detachable from an upper cup section of the outer cup without physically compromising the inner cup to provide access to the accommodation space; and
wherein a tear-off strip or a tear-off line is formed on a side wall of the outer cup between the lower cup section and the upper cup section and runs circumferentially around an outer wall surface of the outer cup andwherein the outer cup has an outer edge flange which protrudes outwards and at least partially surrounds the upper outer cup opening, andwherein the inner cup has an inner edge flange which at least partially surrounds an upper inner cup opening, wherein the inner edge flange comprises two limb portions that each extend downward from a connective portion, and wherein the entire connective portion is thicker along a horizontal direction than each of the two limb portions along a vertical direction.

Abstract
The invention relates to a double-walled cup (1) which comprises an inner and an outer wall as well as a cup opening on its upper end and a bottom part on its lower end. The outer wall is substantially produced from paper, cardboard or the like. The object of the invention is to improve said double-walled cup (1) in such a manner that it can be more rapidly and simply produced and assembled and to reduce the structural stability of the double-walled cup while maintaining its corresponding thermal insulating properties. For this purpose, the inner cup providing the inner wall is inserted into the outer cup (3) providing the outer wall and is secured therein or thereto in an especially detachable manner. The inner cup (2) is produced from an at least fluid-tight plastic material.

2. A double-walled cup comprising:
-
an inner cup having an inner cup side wall and an inner cup bottom, the inner cup being formed from a fluid-tight plastic material; an outer cup having an outer cup side wall and an outer cup bottom, the outer cup being essentially formed from paper or cardboard wherein the inner cup is detachably coupled to and substantially positioned within the outer cup, and wherein the inner cup bottom does not contact the outer cup bottom; an accommodation space between the inner cup bottom and the outer cup bottom; a surprise present contained inside the accommodation space; a tear-off strip in the outer cup formed on the outer cup side wall between an upper and lower section of the outer cup, wherein the tear-off strip runs circumferentially around an outer wall surface of the outer cup, and wherein the tear strip is arranged such that tearing the tear-off strip separates the lower section of the outer cup from the upper section of the outer cup to provide access to the surprise present in the accommodation space without physically compromising the inner cup and wherein the outer cup has an outer edge flange which protrudes outwards and at least partially surrounds the upper outer cup opening, and wherein the inner cup has an inner edge flange which at least partially surrounds an upper inner cup opening, wherein the inner edge flange comprises two limb portions that each extend downward from a connective portion, and wherein the entire connective portion is thicker along a horizontal direction than each of the two limb portions along a vertical direction. - View Dependent Claims (6, 7, 8, 10, 11, 13, 14, 15, 16, 17, 18, 19, 20)
