Abstract
Abstract A one-piece nestable cup is provided with a top rim portion which serves as the upper stacking shoulder for supporting a like container nested therein. A lower stacking shoulder having a greater peripheral extent than the minimum peripheral extent of the top rim is spaced from the top rim and is joined thereto by means of an upwardly and inwardly inclined stacking ring. The stacking ring is provided with a plurality of circumferentially spaced apart lead-in portions to facilitate the engagement of a disc-type lid in an annular groove positioned below the lower shoulder.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
200 words
A one-piece nestable seamless container of thermoplastic material having a bottom, a sidewall extending upwardly and outwardly therefrom, said sidewall terminating at its upper end in a combined stacking and lid seating area, including a. an annular bead extending outwardly from said sidewall and circumferentially therearound, said annular bead defining a lid retaining groove on the inside of the container, b. a top rim portion forming an upper stacking shoulder for supporting a like container nested therein, the minimum radial extent of the top rim portion being greater than the radial extent of said groove, c. an intermediate section joining said annular bead and said top rim portion, said intermediate section including 1. a lower stacking shoulder extending outwardly from said sidewall and having a radial extent greater than the minimum radial extent of said top rim portion to permit nesting of said lower stacking shoulder on the top rim portion of a like container in which it is positioned, and 2. an upwardly and inwardly inclined support ring extending between the lower stacking shoulder and the top rim portion, said support ring having circumferentially spaced apart interruptions defining lead-in portions extending from the top rim to the annular groove.
