Abstract
A dispenser for extruding from a paste tube a paste portion. The dispenser includes a support portion and a cover portion, which have hinges at one end and which enclose a chamber for the paste tube. By pressing on the cover member, a paste portion is extruded from the tube. The hinges are adjustable to suit the tube, when full or one-half full, or near empty. The support portion and cover portion have respective resilient liners for providing a spring rate and for snugly holding the tube.
Claims6
A dispenser for a paste tube comprising:
- a support member having first and second side walls each including a top portion having at least two slotted portions, and a rear wall, said slotted portions extending approximately perpendicular to the rear wall and located at said top portion;
- a cover member having first and second side walls each including a top portion and each having a pin located at said top portion member for positioning in respective ones of the at least two slotted positions;
- a variable-volume chamber disposed between said support member and said cover member and having a selective depth dimension;
- hinge means comprising said pin members and slotted portions for connecting said support member and said cover member;
- said hinge means adjusting said selective depth dimension by positioning thereof between at least a first and second fixed pivotal slotted position, between said support member and said cover member;
- liner means disposed in said chamber for transmitting pressure on said tube caused by a force on said cover member;
- said liner means including,
- a first liner disposed adjacent to and contained by the support member and having a first inner surface;
- a second liner disposed adjacent to and contained by the cover member and having a second inner surface;
- each of the liners composed of a resilient material having a selective spring rate in a direction about normal to its respective inner surface;
- said first inner surface in extended arcuate contact with a first coacting surface portion of the tube;
- and
- said second inner surface in extended arcuate contact with a second coacting surface portion of the tube.

A method of making a paste tube dispenser including the steps of:
- forming a support member and a cover member having a variable-volume chamber disposed therebetween;
- hingingly connecting the cover member to the support member at one end thereof;
- adjusting the distance from the support member to the cover member between at least a first and second fixed slotted povital position to provide a selected inner depth dimension to suit the thickness of a tube;
- and
- adding a first and second resilient liner on inner sides of the support member and cover member respectively with shaped inner surfaces to suit the contour of the tube and for providing desired spring rate when applying a force on the cover member for extruding a paste portion from the tube.
