Abstract

A lid is provided for closing off the open end of one of respective first and second containers, each container a different diameter and having a peripherally disposed bead at its open end. An axially disposed annular inner wall projects downwardly from a central cover portion, and defines a generally circular first annular channel open towards the bottom face of the lid. The upper limit of insertion of the peripherally disposed bead of a first container is defined by a generally planar edge. The wall defining the first annular channel has a radially inwardly extending central portion that forms a first reduced waist portion, which is shaped and dimensioned to retain the peripherally disposed bead of the first container, and also defines the upper limit of insertion of the bead of a second container which has a larger diameter, into a second channel formed in the lid. The second channel is further defined by a radially inwardly extending central portion that forms a second reduced waist portion, which is shaped and dimensioned to retain the peripherally disposed bead of the second container. An annular skirt portion extends downwardly and outwardly at the lower extremity of the lid.

Dependent claims

A container lid for closing off one of different diameter open ends of one of a first container and a second container, wherein each container has a peripherally disposed bead at its open end, said lid comprising:

a central covering panel;
an axially disposed annular wall projecting downwardly from said central covering panel;
a radially inwardly extending first reduced waist portion formed in said axially disposed annular wall;
a first annular channel formed in said axially disposed annular wall immediately above said first reduced waist portion;
a first planar ledge extending inwardly radially at the top of said first annular channel, and adjoining said central covering panel;
wherein said first reduced waist portion and said first annular channel together define a circular first cavity shaped and dimensioned to receive and retain said peripherally disposed bead of a first container;
wherein said first planar ledge defines the upper limit of insertion of the peripherally disposed bead of a first container into said container lid;
a radially inwardly extending second reduced waist portion disposed in said axially disposed annular wall below said first reduced waist portion;
a second annular channel disposed in said axially disposed annular wall immediately above said second reduced waist portion;
wherein said second reduced waist portion and said second annular channel together define a circular second cavity shaped and dimensioned to receive and retain a peripherally disposed bead of a second container;
and
an annular skirt portion extending downwardly and outwardly from said axially disposed annular wall.
