Abstract
Abstract A container and safety lid combination comprising a cylindrical container having a compound safety lid detachably mounted thereon, the safety lid including a centrally apertured outer portion, and an inner portion rotatably mounted in the outer portion for rotation about a vertical axis coincident with the axis of the container. The inner portion of the lid includes a plurality of downwardly extending legs which extend parallel to the axis of the container and along the cylindrical side wall thereof. The legs carry shoulders adapted to engage a rib or bead formed around the upper portion of the container. The outer portion of the lid includes a peripheral, downwardly extending flange positioned outside the legs of the inner portion of the lid, with such flange carrying recesses or relieved portions dimensioned to accomodate the legs of the inner portion in one relative position of the inner and outer portions of the lid. The flange of the outer portion also carries cam surfaces for biasing the legs into engagement with the rib or bead on the container when the inner portion of the lid is rotated relative to the outer portion thereof.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
202 words
A container and safety lid combination comprising: a container having a bottom and an open top, and being substantially circularly cross-sectioned from bottom to top; a rib extending around the upper portion of the container; a safety lid removably engaging and closing the upper end of said container and comprising: a centrally apertured outer portion having a peripheral, downwardly extending flange formed thereon, said flange having circumferentially spaced, leg accommodating recesses formed therein and facing said container; cam segments carried on the inner side of said flange adjacent said recesses and facing said container; an inner portion rotatably mounted in said outer portion and having a portion positioned in the central aperture in said outer portion, and a downwardly extending flange projecting inside the open top of said container; and a plurality of resilient locking legs connected to said inner portion flange and projecting across the top edge of said container and downwardly between the container and the flange of said outer portion, said legs each being dimensioned to be received in said leg-accommodating recesses, and each having a locking shoulder formed thereon for engaging said rib when said legs ride over said cam segments between said cam segments and said container.
Claim 2
Dependent Claim
202 words
A container and safety lid combination comprising: a container having a bottom and an open top, and being substantially circularly cross-sectioned from bottom to top; a rib extending around the upper portion of the container; a safety lid removably engaging and closing the upper end of said container and comprising: a centrally apertured outer portion having a peripheral, downwardly extending flange formed thereon, said flange having circumferentially spaced, leg accommodating recesses formed therein and facing said container; cam segments carried on the inner side of said flange adjacent said recesses and facing said container; an inner portion rotatably mounted in said outer portion and having a portion positioned in the central aperture in said outer portion, and a downwardly extending flange projecting inside the open top of said container; and a plurality of resilient locking legs connected to said inner portion flange and projecting across the top edge of said container and downwardly between the container and the flange of said outer portion, said legs each being dimensioned to be received in said leg-accommodating recesses, and each having a locking shoulder formed thereon for engaging said rib when said legs ride over said cam segments between said cam segments and said container.
Claim 3
Dependent Claim
34 words
A container and safety lid combination as defined in claim 1 wherein each of said cam segments is cHaracterized in having a tapered cam surface at one side thereof adjacent one of said recesses.
Claim 4
Dependent Claim
47 words
A container and safety lid combination as defined in claim 1 wherein said outer portion is further characterized in having: a top wall with said central aperture formed therein; and a stop member projecting downwardly from said top wall radially inwardly of one of said cam segments.
Claim 5
Dependent Claim
60 words
A container and safety lid combination as defined in claim 1 wherein said outer portion is further characterized in having: a top wall with said central aperture formed therein; and a stop member formed on said top wall in a position to engage one of said locking legs to limit movement of said outer portion relative to said inner portion.
Claim 6
Dependent Claim

A container and safety lid combination as defined in claim 1 wherein each of said locking legs is of generally L-shaped configuration, and includes: a web portion projecting radially outwardly from said flange carried by said inner portion and engaging the upper edge of said container; and a locking portion extending downwardly between said container and the flange carried by said outer portion and having said locking shoulder formed on the lower end thereof.
Claim 7
Dependent Claim
61 words
A container and safety lid combination as defined in claim 1 wherein said inner portion is further characterized in including: a top wall positioned in the central aperture in said outer portion; and means engaging a portion of said outer portion to prevent said top wall of said inner portion from being displaced from the central aperture in said outer portion.
Claim 8
Dependent Claim
48 words
A container and safety lid combination as defined in claim 3 and further characterized in including a friction cam secured to said inner portion in a position to frictionally engage said stop member during a portion of the rotation of said inner portion relative to said outer portion.
Claim 9
Dependent Claim
