Abstract
Abstract A nestable vending-type cup of thermoplastic material comprised of a base having an integral peripheral upstanding wall which together with the base forms a liquid reservoir. The free end of the wall is turned over to form an outwardly and downwardly extending collar which extends circumjacent the upper part of the upwardly extending portion of the wall and is spaced therefrom. The collar is so constructed that when gripped by a user, it remains spaced from the upwardly extending portion of the wall. The collar is provided with strengthening features consisting of an outwardly and downwardly inclined shoulder and indents defined with vertical walls lying in radial planes to increase the rigidity of the collar. The construction of the cup provides a cup which is comfortably and easily held by the user when it contains hot beverages and which is also economic to manufacture.

Dependent Claim
161 words
A nestable vending-type cup formed of thin gauge thermoplastic material comprising a base (2) a wall (4) integral with and upstanding from the base (2) to define therewith a liquid reservoir, said wall (4) turned over at its free end to from a collar (6) circumjacent the wall (4), said collar (6) characterized by inclining outwardly and extending downwardly from the wall (4) of the cup for at least 5 mm before a shoulder (14) is provided, said shoulder extending outwardly at a 45° angle from the collar and interposed midway between an upper portion (8) of the collar and a lower flared skirt portion (10), and having a multiplicity of uniformly spaced indents (16) located before the shoulder and on the periphery of the flared skirt portion (10), each of said indents (16) designed to increase the transverse rigidity of the collar such that when the collar is gripped by the user it remains spaced from the upstanding wall (4).
Claim 3
Dependent Claim
