Abstract
Abstract A tamper evident container assembly includes an open-ended container body having a bottom wall and peripheral side wall, the side wall having an upper rim protruding radially outwardly of the peripheral side wall. A reusable lid has a top wall and a portion of which is tucked under the upper rim to thereby lock the lid to the container body. The depending skirt is further provided in a lower portion thereof with an annular line of weakening extending about the skirt portion to thereby define an annular tear strip inclusive of the free end so that upon removal of the tear strip, the lid may be removed from said container. A related method of assembling a tamper evident container assembly the steps of: a) filling the container body with contents; b) applying the lid to the container body; and c) tucking a substantial portion of the lower free edge under the rim to thereby provide a tamper evident container.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
160 words
A tamper evident container assembly comprising: an open-ended container body having a bottom wall and peripheral side wall, said side wall having an upper rim protruding radially outwardly of said peripheral side wall; a reusable lid having a top wall portion constructed of skirt portion, said depending skirt portion constructed of spiral wound stock and having a free end, a major portion of said free end tucked under said upper rim, said skirt portion including the tucked portion being in substantially continuous engagement with said rim to thereby lock said lid to said container body; wherein said depending skirt portion is further provided in a lower portion thereof with a line of weakening extending annularly about said skirt portion to thereby define an annular removable tear strip inclusive of said free end; and further wherein a minor portion of said free end is left untucked to thereby provide a gripping area to facilitate tearing and removal of said tear strip.
Claim 2
Dependent Claim
160 words
A tamper evident container assembly comprising: an open-ended container body having a bottom wall and peripheral side wall, said side wall having an upper rim protruding radially outwardly of said peripheral side wall; a reusable lid having a top wall portion constructed of skirt portion, said depending skirt portion constructed of spiral wound stock and having a free end, a major portion of said free end tucked under said upper rim, said skirt portion including the tucked portion being in substantially continuous engagement with said rim to thereby lock said lid to said container body; wherein said depending skirt portion is further provided in a lower portion thereof with a line of weakening extending annularly about said skirt portion to thereby define an annular removable tear strip inclusive of said free end; and further wherein a minor portion of said free end is left untucked to thereby provide a gripping area to facilitate tearing and removal of said tear strip.
Claim 3
Dependent Claim
29 words
The assembly of claim 1 wherein said top wall and said depending skirt of said lid are separate components seamed together about an upper edge of said depending skirt.
Claim 4
Dependent Claim
