Paste dispenser
First Claim
1. An improved dispenser for pastes comprising:
- a) a paste container having a wall, b) an elastic means having a base configuration, being deformable by application of a force thereto and elastically returning to said base configuration when said application of a force is discontinued, c) a displaceable element, d) said wall, elastic means and displaceable element defining a variable volume paste chamber, e) a dispenser nozzle communicating with said chamber for dispensing paste therefrom, f) said displaceable element being displaced by room pressure, as a result of a reduced pressure in said paste chamber, towards said elastic means upon the return of said elastic means to said base configuration, g) an actuating member, accessible from outside the container and displaceable from an inactive to an active position, and h) means for applying a force to said elastic means to deform said elastic means, in such a way as to reduce the volume of said chamber, thereby causing said paste to be dispensed through said dispenser nozzle, when said actuating member is displaced from the inactive to the active position, and i) a kinematism for kinematically connecting said actuating member to said means for applying a force to said elastic means to deform said elastic means, when said actuating means is displaced to its active position, and for allowing said elastic means elastically to return to said base configuration thereof when said actuating means is returned to its inactive position.

Abstract
An improved dispenser for pastes is disclosed comprising a variable volume paste chamber, a dispenser nozzle communicating with the chamber for dispensing paste, a displaceable element displaced by room pressure, as a result of a reduced pressure in the paste chamber, an actuating member, accessible from outside the container and displaceable from an inactive to an active position, an elastic element, a means for applying a force to the elastic element in such a way as to reduce the volume of the chamber, thereby causing said paste to be dispensed through said dispenser nozzle, when said actuating member is displaced from the inactive to the active position, a kinematism for kinematically connecting the actuating member to the means for applying a force to the elastic element when the actuating member is displaced to its active position, and for allowing the elastic element elastically to return to its base configuration when the actuating member is returned to its inactive position, and a support means for holding the paste container in a predetermined position when a force is applied to the elastic element.

1. An improved dispenser for pastes comprising:
-
a) a paste container having a wall, b) an elastic means having a base configuration, being deformable by application of a force thereto and elastically returning to said base configuration when said application of a force is discontinued, c) a displaceable element, d) said wall, elastic means and displaceable element defining a variable volume paste chamber, e) a dispenser nozzle communicating with said chamber for dispensing paste therefrom, f) said displaceable element being displaced by room pressure, as a result of a reduced pressure in said paste chamber, towards said elastic means upon the return of said elastic means to said base configuration, g) an actuating member, accessible from outside the container and displaceable from an inactive to an active position, and h) means for applying a force to said elastic means to deform said elastic means, in such a way as to reduce the volume of said chamber, thereby causing said paste to be dispensed through said dispenser nozzle, when said actuating member is displaced from the inactive to the active position, and i) a kinematism for kinematically connecting said actuating member to said means for applying a force to said elastic means to deform said elastic means, when said actuating means is displaced to its active position, and for allowing said elastic means elastically to return to said base configuration thereof when said actuating means is returned to its inactive position. - View Dependent Claims (2, 3, 4, 5, 6)

7. An improved dispenser for pastes comprising:
-
a) a paste container having a wall, b) an elastic means having a base configuration, being deformable by application of a force thereto and elastically returning to said base configuration when said application of a force is discontinued, c) a displaceable element, d) said wall, elastic means and displaceable element defining a variable volume paste chamber, e) a dispenser nozzle normally in an inoperative position in which it does not communicate with said chamber, f) said displaceable element being displaced by room pressure, as a result of a reduced pressure in said paste chamber, towards said elastic means upon the return of said elastic means to said base configuration, g) an actuating member, accessible from outside the container and displaceable from an inactive to an active position, and h) means for applying a force to said elastic means to deform said elastic means, in such a way as to reduce the volume of said chamber, thereby causing said paste to be dispensed through said dispenser nozzle, when said actuating member is displaced from the inactive to the active position, and i) a kinematism for kinematically connecting said actuating member to said means for applying a force to said elastic means to deform said elastic means, when said actuating means is displaced to its active position, and for allowing said elastic means elastically to return to said base configuration thereof when said actuating means is returned to its inactive position, wherein the dispenser nozzle is displaceable, upon actuation of the actuating means, to an operative position in which it communicates with the paste chamber to allow dispensation of the paste therefrom.

8. An improved dispenser for pastes comprising:
-
a) a paste container having a wall, b) an elastic means having a base configuration, being deformable by application of a force thereto and elastically returning to said base configuration when said application of a force is discontinued, c) a displaceable element, d) said wall, elastic means and displaceable element defining a variable volume paste chamber, e) a dispenser nozzle communicating with said chamber for dispensing paste therefrom, f) said displaceable element being displaced by room pressure, as a result of a reduced pressure in said paste chamber, towards said elastic means upon the return of said elastic means to said base configuration, g) an actuating member, accessible from outside the container and displaceable from an inactive to an active position, h) means for applying a force to said elastic means to deform said elastic means, in such a way as to reduce the volume of said chamber, thereby causing said paste to be dispensed through said dispenser nozzle, when said actuating member is displaced from the inactive to the active position, i) a kinematism for kinematically connecting said actuating member to said means for applying a force to said elastic means to deform said elastic means, when said actuating means is displaced to its active position, and for allowing said elastic means elastically to return to said base configuration thereof when said actuating means is returned to its inactive position, and j) a support means for holding the paste container in a predetermined position when said force is applied to said elastic means. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
