US 5,307,949 A · Tear-away lid and container

Abstract

A plastic container lid is adapted for removable attachment to a container. The lid comprises spaced inner and outer peripheral walls defining between them a substantially annular sealing seat for a lid retaining ring carried by the container. The outer wall of the lid defines inwardly-positioned projection means to engage the retaining ring of the container, to facilitate retention of the lid on the container. The outer peripheral wall defines at least one circumferentially extending line of tearing weakness to permit separation of at least some of the inwardly positioned projection means from the remainder of the lid. The lid outer wall defines one or more apertures or recesses to provide access to a pry member, to allow prying of the lid away from its retention on a container while causing the line of weakness to tear, permitting removal of the lid and at least partial separation of the projection means from the lid.

A plastic lid having a periphery for removable attachment adjacent its periphery to a container, said lid comprising spaced inner and outer peripheral walls defining between them a substantially annular sealing seat for a lid retaining ring carried by the container, said outer, peripheral wall of the lid defining inwardly-positioned projection means to engage said retaining ring of the container to facilitate retention of the lid on said container;

said outer, peripheral wall defining at least one circumferentially extending line of tearing weakness to permit separation of at least some of said inwardly-positioned projection means from the remainder of said lid, said lid outer peripheral wall defining at least one aperture or recess to provide access for pry member, to allow prying of said lid away from its retention on a bucket while causing said line of weakness to tear, permitting removal of said lid and at least partial separation of said projection means from the lid.

A plastic lid having a periphery for removable attachment adjacent its periphery to a container, said lid comprising spaced inner and outer peripheral walls defining between then a substantially annular sealing seat for a lid retaining ring carried by the container, said outer peripheral wall of the lid defining inwardly-positioned projection means to engage the retaining ring of the container to facilitate retention of the lid on said container;

said outer peripheral wall defining at least one circumferentially extending line of tearing weakness to permit separation of at least some of said inwardly-positioned projection means from the remainder of said lid, said lid outer peripheral wall defining a plurality of spaced apertures to provide access to a pry member, to allow prying of said lid away from its retention on a container while causing said line of weakness to tear, permitting removal of said lid and at least partial separation of said projection means from the lid, said inner peripheral wall defining an annular, outwardly projecting member to sealingly engage the lid retaining ring of a container upon which said lid is carried, each of said apertures being defined below a reinforced portion of the outer peripheral wall proportioned to withstand action of said pry member.

A plastic lid having a periphery which is removably attached to a container by an attachment area adjacent the periphery of said lid, said lid comprising spaced, inner and outer peripheral walls defining between them a substantially annular sealing seat;

a lid retaining ring carried by the container, said retaining ring projecting into said sealing seat;
the outer peripheral wall of the lid defining annular inwardly-positioned projection means to sealingly engage the retaining ring of the container to facilitate retention of the lid on said container;
said outer peripheral wall having a top and defining at least one circumferentially extending line of tearing weakness to permit separation of at least some of said inwardly positioned projection means from the remainder of said lid, said lid outer peripheral wall defining a circumferentially extending recess space from the top of said outer, peripheral wall of the lid to provide access to a pry member, to allow prying of said lid away from its retention on a container while causing said line of weakness to tear, permitting removal of said lid and at least partial separation of said projection means from the lid;
said container having an outer rim surrounding said lid in spaced relation to said lid to provide a fulcrum for said pry member.
