Abstract
Abstract A container lid is formed from a disc having thin walls of uniform thickness throughout which span and overlap the open end of the container. The overlapping portion includes a downwardly depending resilient skirt that partly overlies in engaging relation one surface of the sidewall adjacent the open end. Complementary engagement means are formed in the skirt for releasably engaging lid engagement means such as a continuous bead or groove that comprise an integral part of the container. A reclosable tear strip defines an opening through which the contents of the container may be discharged and forms an integral part of the disc and the skirt. The strip has sides defined by fracture lines formed in the disc, an outer end defined by the lines extending into the skirt to include the complementary engagement means and an inner end forming a hinge along a weakened line in the disc. In one embodiment the tear strip extends to the bottom edge of the skirt while in another, the strip ends before the edge to form a continuous reinforcement band around the container.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
190 words
A lid for a container having an open end defined by a circumferential edge of a sidewall including lid engagement means, the lid comprising: a disc having thin walls of uniform thickness throughout for spanning and overlapping the open end, the overlapping portion including a downwardly depending resilient skirt adapted to partly overlie in engaging relation one surface of the sidewall adjacent said edge; complementary engagement means formed in the skirt for releasably engaging the lid engagement means; a reclosable tear strip forming an integral part of the disc and said skirt, the strip having sides defined by fracture lines formed in the disc, an outer end defined by said lines extending into the skirt to include said complementary engagement means, an inner end forming a hinge along a weakened line in said disc and wherein said lines extending into the skirt terminate at a slot having an upper edge defining the outer end below said complementary engagement means, and a lower edge bounding one side of a strip defined by the lower edge of the slot and a bottom edge of the skirt; and means for venting the container.
Claim 2
Dependent Claim
190 words
A lid for a container having an open end defined by a circumferential edge of a sidewall including lid engagement means, the lid comprising: a disc having thin walls of uniform thickness throughout for spanning and overlapping the open end, the overlapping portion including a downwardly depending resilient skirt adapted to partly overlie in engaging relation one surface of the sidewall adjacent said edge; complementary engagement means formed in the skirt for releasably engaging the lid engagement means; a reclosable tear strip forming an integral part of the disc and said skirt, the strip having sides defined by fracture lines formed in the disc, an outer end defined by said lines extending into the skirt to include said complementary engagement means, an inner end forming a hinge along a weakened line in said disc and wherein said lines extending into the skirt terminate at a slot having an upper edge defining the outer end below said complementary engagement means, and a lower edge bounding one side of a strip defined by the lower edge of the slot and a bottom edge of the skirt; and means for venting the container.
Claim 3
Dependent Claim
16 words
A lid as claimed in claim 1 further comprising a perforatable aperture defined by fracture lines.
Claim 4
Dependent Claim
34 words
A lid as claimed in claim 2 wherein said strip and the remainder of the skirt comprise a continuous resilient band adapted to grip a corresponding portion of the outer surface of the sidewall.
Claim 5
Dependent Claim
45 words
A lid as claimed in claim 3 wherein the complementary engagement means comprise a continuous outstanding tongue facing inwardly of the disc on an inner surface of the skirt, said tongue being adapted to fit a complementary groove in the outer surface of the sidewall.
Claim 6
Dependent Claim
45 words
A lid as claimed in claim 3 wherein the complementary engagement means comprise a continuous groove facing inwardly of the disc on an inner surface of the skirt, said groove being adapted to fit a complementary tongue outstanding from the outer surface of the sidewall.
Claim 7
Dependent Claim
66 words
A lid as claimed in claim 3 wherein the complementary engagement means comprise an annular channel formed in the disc, said channel having an outer wall comprising the skirt and a concentric inner wall depending downwardly from a disc portion overlying said edge of the sidewall, the inner wall being resilient and partly overlying in engaging relation the inner surface of the sidewall adjacent said edge.
Claim 8
Dependent Claim
99 words
A lid as claimed in claim 3 wherein the complementary engagement means comprise: a continuous groove facing inwardly of the disc on an inner surface of the skirt, said groove being adapted to fit a complementary tongue outstanding from the outer surface of the sidewall; and an annular channel formed in the disc, said channel having an outer wall comprising the skirt and a concentric inner wall depending downwardly from a disc portion overlying said edge of the sidewall, the inner wall being resilient and partly overlying in engaging relation the inner surface of the sidewall adjacent said edge.
Claim 9
Dependent Claim
57 words
A lid as claimed in claim 7, further comprising: an adhesive strip overlying a portion of each fracture line defining a side of the tear strip, each adhesive strip having a portion permanently bonded to the tear strip and a corresponding portion releasably bonded to the disc to facilitate resealing the tear strip when it is reclosed.
Claim 10
Dependent Claim
39 words
A lid as claimed in claim 3 wherein the skirt engages the outer surface of the sidewall along a continuous outstanding bead facing inwardly of the disc on an inner surface of the skirt adjacent the bottom edge thereof.
Claim 11
Dependent Claim
75 words
A lid as claimed in claim 9, further comprising: a pull-tab disposed at the outer end of the tear strip and providing a finger grip thereat; and an adhesive strip overlying a portion of each fracture line defining a side of the tear strip, each adhesive strip having a portion permanently bonded to the tear strip and a corresponding portion releasably bonded to the disc to facilitate resealing the tear strip when it is reclosed.
Claim 12
Dependent Claim
45 words
A lid as claimed in claim 10 wherein the complementary engagement means comprise a continuous outstanding tongue facing inwardly of the disc on an inner surface of the skirt, said tongue being adapted to fit a complementary groove in the outer surface of the sidewall.
Claim 13
Dependent Claim
45 words
A lid as claimed in claim 10 wherein the complementary engagement means comprise a continuous groove facing inwardly of the disc on an inner surface of the skirt, said groove being adapted to fit a complementary tongue outstanding from the outer surface of the sidewall.
Claim 14
Dependent Claim
66 words
A lid as claimed in claim 10 wherein the complementary engagement means comprise an annular channel formed in the disc, said channel having an outer wall comprising the skirt and a concentric inner wall depending downwardly from a disc portion overlying said edge of the sidewall, the inner wall being resilient and partly overlying in engaging relation the inner surface of the sidewall adjacent said edge.
Claim 15
Dependent Claim
99 words
A lid as claimed in claim 10 wherein the complementary engagement means comprise: a continuous groove facing inwardly of the disc on an inner surface of the skirt, said groove being adapted to fit a complementary tongue outstanding from the outer surface of the sidewall; and an annular channel formed in the disc, said channel having an outer wall comprising the skirt and a concentric inner wall depending downwardly from a disc portion overlying said edge of the sidewall, the inner wall being resilient and partly overlying in engaging relation the inner surface of the sidewall adjacent said edge.
