Abstract

Abstract A plastic container with a detachably connectable lid having the diameter and circumferential features of a conventional metal paint can is disclosed. The top section of the container includes a projection defining the top end of the wall of the middle section, a neck and an annular bead for engaging the lid. The lid includes an outer flexible leg that snaps over the neck and bead of the top section. The lid can be easily removed by inserting a screwdriver between the lid and the top section in a provided space and lifting the screwdriver. The bottom section of the container includes a projection defining the bottom end of the wall of the middle section, and with the lid are adapted to allow stacking of the container/lid combinations. The projection adjacent the top and bottom of the middle section of the container enable the container to be handled by labeling machinery used in conjunction with conventional metal paint cans.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 360 words
A plastic container and detachably disposed lid in combination, (a) said container including a middle section having a cylindrical shape with a generally constant wall thickness; a bottom section integral with said middle section and including a projection defining the bottom part of said middle section; an upper section integral with said middle section and including a projection defining the top part of said middle section wherein said middle section and the first and second mentioned projections are congruent with the outer dimensions of the wall and the location of the upper and lower beads of a conventional one-gallon metal paint container; said upper section also includes an integral neck having a wall portion directed upwardly and inwardly and a straight vertical wall portion in which the inner surface of the vertical wall portion is cylindrical having no projections, recesses or slanted surfaces, said neck terminating with an annular bead, wherein said upwardly and inwardly directed wall portion and said vertical wall portion have a constant wall thickness of approximately the same dimension as the wall thickness of said middle section; and (b) said lid having an annular, generally flat surface, a recessed middle portion, and a perimetral flexible leg including an internal lip for engaging the bead of said upper section, said lid when placed on the container being disposed such that the end of the leg at the lowest portion of the lid is spaced above and substantially inwardly of the projection defining the top part of the middle section so that the major portion of said upwardly and inwardly directed wall portion below said leg is viewable when viewing said upwardly and inwardly directed wall portion in a horizontal plane when said container is in an upright position, said projection of said upper section serving as a fulcrum for a tool used to remove the lid from the container by inserting an end of the tool under the leg and pivoting the tool at the projection, said leg being spaced from said vertical wall portion below the engagement of said internal lip and said bead with the spacing gradually increasing as the distance from said engagement increases.
Claim 2
Dependent Claim 360 words
A plastic container and detachably disposed lid in combination, (a) said container including a middle section having a cylindrical shape with a generally constant wall thickness; a bottom section integral with said middle section and including a projection defining the bottom part of said middle section; an upper section integral with said middle section and including a projection defining the top part of said middle section wherein said middle section and the first and second mentioned projections are congruent with the outer dimensions of the wall and the location of the upper and lower beads of a conventional one-gallon metal paint container; said upper section also includes an integral neck having a wall portion directed upwardly and inwardly and a straight vertical wall portion in which the inner surface of the vertical wall portion is cylindrical having no projections, recesses or slanted surfaces, said neck terminating with an annular bead, wherein said upwardly and inwardly directed wall portion and said vertical wall portion have a constant wall thickness of approximately the same dimension as the wall thickness of said middle section; and (b) said lid having an annular, generally flat surface, a recessed middle portion, and a perimetral flexible leg including an internal lip for engaging the bead of said upper section, said lid when placed on the container being disposed such that the end of the leg at the lowest portion of the lid is spaced above and substantially inwardly of the projection defining the top part of the middle section so that the major portion of said upwardly and inwardly directed wall portion below said leg is viewable when viewing said upwardly and inwardly directed wall portion in a horizontal plane when said container is in an upright position, said projection of said upper section serving as a fulcrum for a tool used to remove the lid from the container by inserting an end of the tool under the leg and pivoting the tool at the projection, said leg being spaced from said vertical wall portion below the engagement of said internal lip and said bead with the spacing gradually increasing as the distance from said engagement increases.
Claim 3
Dependent Claim 25 words
A container as claimed in claim 1 wherein: the inward disposition of said neck is approximately five times the wall thickness of said middle section.
Claim 4
Dependent Claim 46 words
A container as claimed in claim 1 wherein: the diameter of said middle section at an inner wall is 6.43 inches; the diameter of the inner wall at the annular bead is 5.78 inches; and the wall thickness of said middle section is approximately 0.06 inches.
