Abstract
Abstract A container having a bottom, a continuous side wall, and an open top with a rim including an inwardly and downwardly inclined flange and an abutment terminating the flange; with a rigid flat closure of the shape of the rim and flange, said closure having a diameter greater than that of the flange at its inner edge and less than the diameter of the rim, said closure distorting the flange and having a friction fit therewith when pressed into it, the abutment serving to prevent the closure from being pressed too far into the container. This container may be made for the purpose or it may be made by cutting the top out of a discarded beer or soft-drink can.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
160 words
A box comprising a bottom, a cylindrical side wall, and an open top defined by a rim, a partial top member on the rim, a flange on the top member, said flange including a wall extending inwardly and downwardly with respect to the box rim at an incline to the side wall, the flange wall being of even thickness throughout and being resilient and distortable, said flange thereby having an outer wider edge portion at the top of the wall and an inner lesser edge portion at the bottom of the wall, a closure, said closure comprising a rigid coplanar circular disc having an edge conforming to the flange and having a diameter less than the wider edge portion of the flange and greater than the lesser edge portion thereof, said closure being press-fitted to the flange wall and held in position thereby, by friction only of the circumferential edge of the coplanar disc with a surface of the wall.
Claim 2
Dependent Claim
160 words
A box comprising a bottom, a cylindrical side wall, and an open top defined by a rim, a partial top member on the rim, a flange on the top member, said flange including a wall extending inwardly and downwardly with respect to the box rim at an incline to the side wall, the flange wall being of even thickness throughout and being resilient and distortable, said flange thereby having an outer wider edge portion at the top of the wall and an inner lesser edge portion at the bottom of the wall, a closure, said closure comprising a rigid coplanar circular disc having an edge conforming to the flange and having a diameter less than the wider edge portion of the flange and greater than the lesser edge portion thereof, said closure being press-fitted to the flange wall and held in position thereby, by friction only of the circumferential edge of the coplanar disc with a surface of the wall.
Claim 3
Dependent Claim
36 words
The box of claim 1 including an inward projection on the flange at its lesser edge portion, said projection forming a part of an original lid for the top, removed prior to application of the closure.
Claim 4
Dependent Claim
31 words
The box of claim 2 wherein the closure rests on the projection, the latter positioning the closure at least in part within the flange wall adjacent the lesser edge portion thereof.
Claim 5
Dependent Claim
18 words
The box of claim 1 including a crimp on the top member securing the flange to the rim.
Claim 6
Dependent Claim
15 words
The box of claim 4 wherein the flange is in inward extension of said crimp.
Claim 7
