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.
