Abstract

Abstract A manually operated agitator for installation in a container of a thixotropic suspension such as catsup or the like. An enlargement for agitating the suspension by movement therethrough and means for securing the enlargement interior of the container to afford movement in two directions. The securing means is fixed to the interior wall of the container remote from the neck opening of the container and secures the enlargement for movement in a direction generally axially of the container and in a direction generally radially of the point of securement.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 153 words
An agitator for facilitating dispensing a thixotropic suspension from a container having small neck aperature and a wall portion disposed remote from said opening and spaced therefrom comprising a rigid enlargement having a diameter less than said opening, an elongate rod member having a first end fixed to said enlargement and a second end remote from said first end, said elongate rod member having a length less than the distance from said wall portion to said neck opening, and means for securing said agitator to said wall portion, said securing means having a ring rigid with the second end of said rod, a loop interlinked with said ring, said ring and loop defining openings substantially larger than the diameter of the members respectively forming the ring and the loop so as to afford axial and pivotal movement to said rod and said enlargement, and means for attaching said loop to said wall portion.
Claim 2
Dependent Claim 153 words
An agitator for facilitating dispensing a thixotropic suspension from a container having small neck aperature and a wall portion disposed remote from said opening and spaced therefrom comprising a rigid enlargement having a diameter less than said opening, an elongate rod member having a first end fixed to said enlargement and a second end remote from said first end, said elongate rod member having a length less than the distance from said wall portion to said neck opening, and means for securing said agitator to said wall portion, said securing means having a ring rigid with the second end of said rod, a loop interlinked with said ring, said ring and loop defining openings substantially larger than the diameter of the members respectively forming the ring and the loop so as to afford axial and pivotal movement to said rod and said enlargement, and means for attaching said loop to said wall portion.
Claim 3
Dependent Claim 15 words
An agitator according to claim 1 wherein said enlargement comprises a substantially spherical shaped member.
Claim 4
Dependent Claim 34 words
An agitator according to claim 2 wherein said spherical shaped member includes a core of relatively dense material totally encased by a relatively lightweight material, said lightweight material being inert to the thixotropic suspension.
Claim 5
Dependent Claim 36 words
An agitator according to claim 1 wherein said enlargement includes at least one vane secured to said elongate member, said vane having a plane surface generally parallel to the axis of elongation of said elongate member.
Claim 6
Dependent Claim 130 words
An agitator for facilitating dispensing a thixotropic suspension from a container having small neck aperature and a wall portion disposed remote from said opening and spaced therefrom comprising a rigid enlargement having a diameter less than said opening, an elongate member having a first end fixed to said enlargement and a second end remote from said first end, said elongate member having a length less than the distance from said wall portion to said neck opening, said elongate member having a plurality of closed links mutually interlinked to form a chainlike member, at least some of the links having an opening substantially greater than the diameter of the part that forms the opening to afford axial and pivotal movement, and means for securing said second end to said wall portion.
Claim 7
Dependent Claim 130 words
An agitator for facilitating dispensing a thixotropic suspension from a container having small neck aperature and a wall portion disposed remote from said opening and spaced therefrom comprising a rigid enlargement having a diameter less than said opening, an elongate member having a first end fixed to said enlargement and a second end remote from said first end, said elongate member having a length less than the distance from said wall portion to said neck opening, said elongate member having a plurality of closed links mutually interlinked to form a chainlike member, at least some of the links having an opening substantially greater than the diameter of the part that forms the opening to afford axial and pivotal movement, and means for securing said second end to said wall portion.
Claim 8
Dependent Claim 139 words
An agitator for facilitating dispensing a thixotropic suspension from a container having small neck aperature and a wall portion disposed remote from said opening and spaced therefrom comprising a rigid enlargement having a diameter less than said opening, an elongate rod member having a first end fixed to said enlargement and a second end remote from said first end, said elongate rod member having a length less than the distance from said wall portion to said neck opening, and means for securing said agitator to said wall portion, said securing means having a loosely fitting ball and socket joint including a socket defining a spherical cavity fixed to said second end, a ball having a diameter less than that of the spherical cavity to afford axial and pivotal movement, and means for attaching said ball to said wall portion.
Claim 9
Dependent Claim 139 words
An agitator for facilitating dispensing a thixotropic suspension from a container having small neck aperature and a wall portion disposed remote from said opening and spaced therefrom comprising a rigid enlargement having a diameter less than said opening, an elongate rod member having a first end fixed to said enlargement and a second end remote from said first end, said elongate rod member having a length less than the distance from said wall portion to said neck opening, and means for securing said agitator to said wall portion, said securing means having a loosely fitting ball and socket joint including a socket defining a spherical cavity fixed to said second end, a ball having a diameter less than that of the spherical cavity to afford axial and pivotal movement, and means for attaching said ball to said wall portion.
