Abstract
Abstract A sealable and resealable container is provided having a novel locking means, a portion of which is carried by the lid part and the other portion of which is carried by the body of the container. The portion carried by the body comprises a plurality of flexible lock tab members integrally formed in a peripheral band which is attached to but circumferentially spaced from the side wall of the body adjacent its open top. The other portion is carried by the lid and comprises a depending circumferential flange which terminates in a radial, outwardly extending rib. In securing the lid to the body, the flange is inserted between the peripheral band and the side wall of the body, and pressure is applied until the rib first clears and then is engaged by the lower ends of the lock tab members. To remove the lid, the lock tab members are first disengaged from locking engagement with the rib and upward pressure is applied on the rib until the lid is removed. The upper edge of the side wall of the body is preferably tapered to snugly fit into a convergent groove on the lid part in firmly sealing the lid to the body.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
186 words
A plastic sealable and resealable container having a lid part and a body part, said body part comprising a bottom, a side wall, and having an open top; a peripheral band adjacent said open top circumferentially spaced from and secured to said side wall by a plurality of circumferentially spaced radial members extending from said side wall to the lower edge of said band; a plurality of flexible lock tabs integrally formed with and circumferentially spaced about said peripheral band between said radial members, the lower portions of said lock tabs being separated from said peripheral band by vertical slots and inclined toward The side wall of said body; said lid part comprising a planar surface having a raised shoulder at its outer circumferential edge; a circumferential flange depending from said raised shoulder and terminating in an outwardly extending radial rib; and a convergent annular groove formed in said raised shoulder adjacent said circumferential flange adapted to receive the upper edge of said body part as the depending flange of said lid slides between said body part and peripheral band for engagement by said lock tabs.
Claim 2
Dependent Claim
186 words
A plastic sealable and resealable container having a lid part and a body part, said body part comprising a bottom, a side wall, and having an open top; a peripheral band adjacent said open top circumferentially spaced from and secured to said side wall by a plurality of circumferentially spaced radial members extending from said side wall to the lower edge of said band; a plurality of flexible lock tabs integrally formed with and circumferentially spaced about said peripheral band between said radial members, the lower portions of said lock tabs being separated from said peripheral band by vertical slots and inclined toward The side wall of said body; said lid part comprising a planar surface having a raised shoulder at its outer circumferential edge; a circumferential flange depending from said raised shoulder and terminating in an outwardly extending radial rib; and a convergent annular groove formed in said raised shoulder adjacent said circumferential flange adapted to receive the upper edge of said body part as the depending flange of said lid slides between said body part and peripheral band for engagement by said lock tabs.
Claim 3
Dependent Claim
25 words
The container of claim 1 wherein eight radial members are provided about said side wall and eight lock tabs are disposed between said radial members.
Claim 4
Dependent Claim
17 words
The container of claim 2 wherein said radial members are inclined upwardly away from said side wall.
Claim 5
Dependent Claim
23 words
The container of claim 1 wherein said lock tabs are inclined toward said side wall at an angle of about 10* - 20*.
Claim 6
Dependent Claim
53 words
The container of claim 1 wherein the upper edge of the side wall of said body is tapered inwardly and the configuration of said convergent annular groove is adapted to closely receive said tapered upper edge such that a snug fit is provided between said lid and said body in sealing the container.
Claim 7
Dependent Claim
55 words
The container of claim 5 wherein said lid has a downwardly extending shoulder adjacent said raised shoulder, said downwardly extending shoulder having a downwardly extending annular groove formed therein which, together with said convergent groove, forms a common wall facilitating compressive deformation in engagement between said convergent groove and the upper edge of said container.
Claim 8
Dependent Claim
54 words
The container of claim 1 wherein the lower faces of said lock tabs and the upper face of said rib have a slight downward inclination in the direction of said side wall such that said locking engagement of said lock tabs with said rib is enhanced by axial pressures tending to separate the parts.
Claim 9
Dependent Claim
26 words
The container of claim 1 wherein means are provided diametrically opposed on the side wall of said body to receive a bale for carrying said container.
Claim 10
Dependent Claim
48 words
The container of claim 1 wherein said body has an annular downward extension of said side wall adjacent said bottom wall and said lid has an annular raised bead spaced inwardly from said raised shoulder, said annular extension and said raised bead providing means for stacking sealed containers.
