Claim 1
Independent Claim
130 words
A dispensing arrangement for a composite plastic and paperboard lid, comprising: (a) an annular molded plastic rim including an outer, side flange, adapted for attachment to a wall of a container body, and an integral, inner, end flange extending radially inward therefrom; (b) a relatively thin paperboard central panel having a marginal portion of its upper surface bonded to a lower surface of said rim end flange; (c) said rim including an integral tab pivotally mounted with respect thereto and having one end engageable with a portion of said central panel whereby when the other end of said tab is lifted said one end will be depressed and will force a portion of said central panel away from said rim end flange to provide a dispensing opening in said lid.
Claim 2
Dependent Claim
130 words

Claim 3
Dependent Claim
107 words
A dispensing arrangement for a composite plastic and paperboard lid, comprising: (a) an annular molded plastic rim including an outer, side flange, adapted for attachment to a wall of a container body, and an integral, inner, end flange extending radially inward therefrom; (b) a relatively thin paperboard central panel having a marginal portion of its upper surface bonded to a lower surface of said rim end flange; (c) said rim including an integral tab movably engageable with a portion of said central panel and operable to force a portion of said central panel away from said rim end flange to provide a dispensing opening in said lid.
Claim 4
Dependent Claim
107 words
A dispensing arrangement for a composite plastic and paperboard lid, comprising: (a) an annular molded plastic rim including an outer, side flange, adapted for attachment to a wall of a container body, and an integral, inner, end flange extending radially inward therefrom; (b) a relatively thin paperboard central panel having a marginal portion of its upper surface bonded to a lower surface of said rim end flange; (c) said rim including an integral tab movably engageable with a portion of said central panel and operable to force a portion of said central panel away from said rim end flange to provide a dispensing opening in said lid.
