Abstract
Abstract A tightly fitting lid for a pail or bucket has a dispensing opening for discharge of the material contained in the pail and a child-resistant closure for the opening. The lid and pail constitute a package for particulate material. The lid and pail have co-operating rib and recess for retaining the lid on the pail. The lid opening is provided by a short "wide-mouth" neck which is threaded to mate with threads on the closure. The lid and closure have at least one interengaging stop and lug, respectively, which prevent the closure from being unscrewed. The closure can be removed after it is radially deformed in order to disengage the lug from the stop. The diameter of the closure is such that the closure lug cannot be disengaged from the stop by a child of tender years whose hand is too small to span the closure. The lid also has a plurality of horizontally extending webs surrounding and spaced from the closure for supporting a superposed pail.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
144 words
A lid for a pail or bucket, said lid and the rim of said pail having co-operating snap-over means for retaining said lid on said pail, said lid having (a) a short, centrally located neck, (b) an annular body, integral with and surrounding said neck, (c) an inner annular skirt at the periphery of said body and extending upwardly therefrom to a level above the top of said neck, (d) a rim at the junction on said body and said inner skirt that is adapted to tightly fit the inner surface of the pail, (e) an outer annular skirt depending from the upper end of said inner skirt which is adapted to fit circumjacently to the outer side of the pail, (f) a removable closure for said neck, and (g) co-operating, disengageable child-resistant means on said body near said neck and on said closure.
Claim 2
Dependent Claim
144 words
A lid for a pail or bucket, said lid and the rim of said pail having co-operating snap-over means for retaining said lid on said pail, said lid having (a) a short, centrally located neck, (b) an annular body, integral with and surrounding said neck, (c) an inner annular skirt at the periphery of said body and extending upwardly therefrom to a level above the top of said neck, (d) a rim at the junction on said body and said inner skirt that is adapted to tightly fit the inner surface of the pail, (e) an outer annular skirt depending from the upper end of said inner skirt which is adapted to fit circumjacently to the outer side of the pail, (f) a removable closure for said neck, and (g) co-operating, disengageable child-resistant means on said body near said neck and on said closure.
Claim 3
Dependent Claim
55 words
A lid for a pail according to claim 1 in which the closure has a deformable skirt which extends concentrically around the neck and the child-resistant means comprise an opposed lug and stop on said skirt and the container body adjacent said neck which are disengageable by outwardly deforming a portion of said closure skirt.
Claim 4
Dependent Claim
50 words
A lid for a pail according to claim 1 and a circumferentially extending series of spacers on the lid body located between the neck and the inner skirt and which extend upwardly a distance sufficient for supporting a superposed pail with no contact between the superposed pail and the closure.
Claim 5
Dependent Claim
189 words
A lid for a pail or bucket, said lid having (a) an outermost annular skirt adapted to fit circumjacently of the rim of said pail, (b) an inner skirt which depends from the upper edge of said outer skirt and which has an annular sealing lip at its lower margin, said lip fitting tightly against the inner surface of said pail, (c) a disc-like body extending across said lid at the lower margin of said inner skirt, (d) a threaded neck centrally located in said body and extending upwardly to a level below the level of the upper edge of said outer skirt, (e) a cup-shaped closure for said neck, said closure having radially spaced, concentric inner and outer skirts, (f) co-operating means on said neck and the inner side of said inner skirt of said closure for retaining said closure on said neck, and (g) co-operating child-resistant means on said outer skirt of said closure and on said lid adjacent the outer side of said neck for normally preventing the removal of said closure from closed position, said outer skirt being radially deformable for disengaging said child-resistant means.
Claim 6
Dependent Claim
189 words
A lid for a pail or bucket, said lid having (a) an outermost annular skirt adapted to fit circumjacently of the rim of said pail, (b) an inner skirt which depends from the upper edge of said outer skirt and which has an annular sealing lip at its lower margin, said lip fitting tightly against the inner surface of said pail, (c) a disc-like body extending across said lid at the lower margin of said inner skirt, (d) a threaded neck centrally located in said body and extending upwardly to a level below the level of the upper edge of said outer skirt, (e) a cup-shaped closure for said neck, said closure having radially spaced, concentric inner and outer skirts, (f) co-operating means on said neck and the inner side of said inner skirt of said closure for retaining said closure on said neck, and (g) co-operating child-resistant means on said outer skirt of said closure and on said lid adjacent the outer side of said neck for normally preventing the removal of said closure from closed position, said outer skirt being radially deformable for disengaging said child-resistant means.
Claim 7
Dependent Claim
34 words
A lid according to claim 4 and a circumferential recess at the inner side of the junction of the inner and outer lid skirts for the reception and retention of a pail rim bead.
Claim 8
Dependent Claim
171 words
A package for dry, particulate material, said package consisting of (a) a pail having a frusto-conical body, a circular bottom which has an axially extending, annular flange around its periphery and a circular top rim of diameter larger than the diameter of said flange, (b) a circular lid for said pail, said lid having (1) radially spaced, concentric inner and outer skirts joined at their upper ends, said outer skirt fitting closely circumjacent said rim and the peripheral edge of said inner skirt fitting tightly against the inner surface of said pail body below said rim, (2) an annular body extending inwardly from the lower portion of said inner skirt, (3) a centrally located, threaded neck of diameter less than the diameter of said inner skirt, and (4) a series of horizontal spacers on said body and extending around said neck for supporting a superposed pail, and (c) a threaded closure for said neck, said lid and said pail rim having inter-fitting snap-over means for retaining said lid on said pail.
Claim 9
Dependent Claim
171 words
A package for dry, particulate material, said package consisting of (a) a pail having a frusto-conical body, a circular bottom which has an axially extending, annular flange around its periphery and a circular top rim of diameter larger than the diameter of said flange, (b) a circular lid for said pail, said lid having (1) radially spaced, concentric inner and outer skirts joined at their upper ends, said outer skirt fitting closely circumjacent said rim and the peripheral edge of said inner skirt fitting tightly against the inner surface of said pail body below said rim, (2) an annular body extending inwardly from the lower portion of said inner skirt, (3) a centrally located, threaded neck of diameter less than the diameter of said inner skirt, and (4) a series of horizontal spacers on said body and extending around said neck for supporting a superposed pail, and (c) a threaded closure for said neck, said lid and said pail rim having inter-fitting snap-over means for retaining said lid on said pail.
