Abstract
A combination molded plastic bucket and lid includes a series of outwardly extending ribs on the top edge of the bucket and inwardly extending flanges on a depending outer skirt of the lid which engage with the bucket ribs to provide a wedging action that holds the lid tightly in a sealing position on the top of the bucket. A zig-zag tear strip permits removal of a portion of the lower most lid flange. The top of the bucket includes a groove adapted to receive a projection or tongue seal.
Claims25
A bucket and removable lid construction comprising, in combination:
- a bucket having a generally cylindrical side wall with an open top, said top including a first radially outwardly extending, circumferential top rib, said top rib including a top side and an underside, said bucket also including a second radially outwardly extending side rib vertically spaced from the underside of the first rib and including a second rib underside;
- and
- a lid including a center panel for covering the open top of the bucket, said lid further including a peripheral, annular section with an outer depending skirt, said outer skirt including:
- a first radially inwardly extending, circumferential locking flange for engaging against the underside of the bucket top rib, said skirt further including a second radially inwardly extending locking flange for engaging against the underside of the bucket second rib, said second locking flange spaced from said first locking flange approximately the distance of the spacing of the bucket ribs to enable the first and second locking flanges to retain the lid on the bucket, and said skirt further including a skirt extension from the second flange, said skirt and skirt extension including a tear strip to permit removal of portions thereof, said tear strip including portions of the second flange which are permanently removed from engagement with the second rib upon removal of the tear strip, other portions of the second flange remaining for engagement with the second rib upon removal of the tear strip said first flange being circumferentially engaged with the first rib upon removal of the tear strip.

A container and removable lid construction comprising, in combination:
- a container having a side wall with an open top, said top including a first outwardly extending top rib, said top rib including a top side and an underside, said container also including a second outwardly extending side rib vertically spaced from the first rib and having an underside;
- and
- a lid for covering the open top of the container, said lid including a peripheral, depending outer skirt, said outer skirt including:
- (a) a first inwardly extending, circumferential locking flange for engaging against the underside of the container top rib,
- (b) a second inwardly extending, circumferential locking flange for engaging against the underside of the second container side rib, said second locking flange spaced from the first locking flange approximately the distance of the spacing of the container side ribs to enable the locking flanges to retain the lid on the container, and
- (c) a skirt extension from the second locking flange, said skirt extension comprising a tear strip of material from the skirt including selected portions of said second locking flange.

A bucket and removable lid construction comprising, in combination:
- a bucket having a generally cylindrical side wall with an open top, said top comprising a first radially outwardly extending circumferential top rib, said top rib including a top side and an underside, said bucket also including a second radially outwardly extending side rib vertically spaced from the underside of the first rib and including a second rib underside;
- and
- a lid for covering the open top of the bucket, said lid including a peripheral, annular section with an outer depending skirt, said outer skirt including:
- a first radially inwardly extending, elastically deformable circumferential locking flange for engaging against the underside of the bucket top rib, said skirt further including a second radially inwardly extending, elastically deformable locking flange for engaging against the underside of the bucket second rib, said second locking flange spaced from said first locking flange approximately the distance of the spacing of the bucket ribs to enable the first and second locking flanges to retain the lid on the bucket, and said skirt further including a skirt extension from the second flange, said skirt and skirt extension including a tear boundary to define a tear strip for removal from the lid, said tear strip including portions of the second flange which are permanently removed from engagement with the second rib upon removal of the tear strip, other portions of the second flange remaining for engagement with the second rib upon removal of the tear strip, said first flange being circumferentially engaged with the first rib upon removal of the tear strip.
