Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
160 words
In an over-cap device having wedge projections extending a major distance radially inwardly and adapted for grasping substantially cylindrical outer walls of a container lid or cap, the improvement comprising in combination: a unitary molded resilient plastic cap means defining a top substantially horizontal inner wall having a periphery and having substantially cylindrical inner side walls downwardly extending from a plurality of points around said periphery, and the cylindrical inner side walls at a plurality of spaced-apart locations having at each of said spaced-apart locations a projection extending radially-inwardly a predetermined distance beneath a lower horizontal face of the top substantially horizontal inner wall, each projection having an upper, upwardly-facing edge spaced-from said lower face; and as mechanism for said grasping by wedge action, at least one of said projection having a radially-inwardly-facing edge; said upwardly-facing edge extending radially inwardly beyond the point of said plurality of points, of attachment the cylindrical inner side wall of the spaced-apart location thereabove.
Claim 2
Dependent Claim
160 words
In an over-cap device having wedge projections extending a major distance radially inwardly and adapted for grasping substantially cylindrical outer walls of a container lid or cap, the improvement comprising in combination: a unitary molded resilient plastic cap means defining a top substantially horizontal inner wall having a periphery and having substantially cylindrical inner side walls downwardly extending from a plurality of points around said periphery, and the cylindrical inner side walls at a plurality of spaced-apart locations having at each of said spaced-apart locations a projection extending radially-inwardly a predetermined distance beneath a lower horizontal face of the top substantially horizontal inner wall, each projection having an upper, upwardly-facing edge spaced-from said lower face; and as mechanism for said grasping by wedge action, at least one of said projection having a radially-inwardly-facing edge; said upwardly-facing edge extending radially inwardly beyond the point of said plurality of points, of attachment the cylindrical inner side wall of the spaced-apart location thereabove.
Claim 3
Dependent Claim
20 words
In an over-cap device of claim 1, the improvement further including a plurality of said projections having said radially-inwardly-facing edge.
Claim 4
Dependent Claim
48 words
In an over-cap device of claim 2, the improvement further including a lower portion of the radially-inwardly-facing edge being slanted obliquely downwardly and further radially inwardly than an upper portion of the radially-inwardly-facing edge, adapted such that a catch-abutment is thereby formed which latches onto a container top.
Claim 5
Dependent Claim
64 words
In an over-cap device of claim 3, the improvement further including said lower portion extending radially-inwardly to an extent less than a radius of said top substantially horizontal inner wall, and in which for said plurality of said projections each projection defines laterally an acute angle to a plane of the downwardly extending wall from the location at from which the respective projection extends.
Claim 6
Dependent Claim
57 words
In an over-cap device of claim 3, the improvement further including said lower portion extending as a shaft radially-inwardly to an extent less than a radius of said top substantially horizontal inner wall, and in which for said plurality of said projections includes each projection a finger element extending at about a right angle to said shaft.
Claim 7
Dependent Claim
14 words
In an over-cap device of claim 5, the improvement including said finger extending laterally.
Claim 8
Dependent Claim
26 words
In an over-cap device of claim 5, the improvement including said finger extending in a plane about upright relative to said top substantially horizontal inner wall.
Claim 9
Dependent Claim
48 words
In an over-cap device of claim 1, the improvement further including a lower portion of the radially-inwardly-facing edge being slanted obliquely downwardly and further radially inwardly than an upper portion of the radially-inwardly-facing edge, adapted such that a catch-abutment is thereby formed which latches onto a container top.
