Abstract
Abstract A device for squeezing collapsible tubes such as toothpaste tubes characterized by three members interconnected together along one end thereof to form a V-shaped compartment diverging from the one end for receiving a toothpaste tube. The outer two members are substantially planar and the inner member is longitudinally curved and arranged with the convex curve surface adapted to engage the tube so that the application of pressure to the tube is moved progressively from the one end towards the head of the tube. In the preferred embodiment, the means for holding the three members together includes foot means for enabling the storage of the tube and the dispenser in the upright position, and the pressure member acting on the curved member has a movable block for transferring the squeezing force to the curved member so that the point of transfer can be shifted to increase or decrease the leverage applied to the flexible member.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
205 words
A device for squeezing the contents from a collapsible container having a head portion at one end with an opening for removing the contents of the tube and the other end of the tube being closed with a substantially straight line seam, said device comprising a pair of pressure members with each of said pair of members having a substantially planar pressure surface; a third member having a curved configuration extending along a longitudinal axis to provide a longitudinally extending curved surface, said third member being disposed between said pair of members; and resilient means for holding the pair of pressure members and the third member together at one end thereof with the curved surface of the third member contacting one of said pairs of members at said one end and diverging from said one member as the distance from said one end increases to form a means for receiving a collapsible container with the closed end disposed at said one end so that pressure applied to the pair of pressure members causes the squeezing of the contents from the collapsible container with the third member applying a squeezing action moving progressively from the one end of the one pressure member towards the other end.
Claim 2
Independent Claim
205 words
A device for squeezing the contents from a collapsible container having a head portion at one end with an opening for removing the contents of the tube and the other end of the tube being closed with a substantially straight line seam, said device comprising a pair of pressure members with each of said pair of members having a substantially planar pressure surface; a third member having a curved configuration extending along a longitudinal axis to provide a longitudinally extending curved surface, said third member being disposed between said pair of members; and resilient means for holding the pair of pressure members and the third member together at one end thereof with the curved surface of the third member contacting one of said pairs of members at said one end and diverging from said one member as the distance from said one end increases to form a means for receiving a collapsible container with the closed end disposed at said one end so that pressure applied to the pair of pressure members causes the squeezing of the contents from the collapsible container with the third member applying a squeezing action moving progressively from the one end of the one pressure member towards the other end.
Claim 3
Dependent Claim
69 words
A device according to claim 1, wherein the other of said pair of pressure members supports a movable block for transferring the pressure applied to said other pressure member to the third member, said block being movable on said other pressure member to shift the point of application of the pressure transfer to the third member thereby changing the leverage placed on the container being squeezed by the device.
Claim 4
Dependent Claim
38 words
A device according to claim 1, wherein the one member of said pair of pressure members has a thickness substantially greater than the thickness of the third member and the other member of said Pair of pressure members.
Claim 5
Dependent Claim
73 words
A device according to claim 1, wherein said resilient means comprises a pair of spring connectors spaced apart at the one end of said members to provide a slot between the third member and the one of said pair of said pressure members at said one end, said slot being adapted to receive the flattened end of the container which end is created after removal of some of the contents of the container.
Claim 6
Dependent Claim
53 words
A device according to claim 1, wherein said resilient means includes a spring extending between a pair of foot members, said foot members acting on the outer surfaces of the pair of pressure members and having support surfaces for enabling an upright storage of the device with the one end being the base.
Claim 7
Dependent Claim
52 words
A device according to claim 5, wherein at least one of said pressure members has slots for receiving the spring of the resilient means so that the pressure member is removably assembled with the other members and is removable to enable cleaning of the pair of pressure members and the third member.
Claim 8
Dependent Claim
143 words
A device according to claim 1, wherein the resilient means are a pair of springs spaced from each other at said one end of said members, said springs include block members engaging the outer surfaces of each of the pressure members to urge the one end of the pair of pressure members into engagement with the third member, said block members having support surfaces enabling the positioning of the device on said one end, and wherein the other of said pair of pressure members has a force transfer means disposed thereon for transferring force applied to said other pressure member to the third member, said force transfer means being movably mounted on said other member so that the point of transfer to the third member can be shifted with respect to the one end to vary the leverage applied to the third member.
Claim 9
Dependent Claim
46 words
A device according to claim 7, wherein said force transfer means is a member pivotally connected to the other of said pair of pressure members, so that pivoting of said member through an arc of 180* shifts the point of transfer for the force transfer means.
