Abstract
A dispenser for simultaneously dispensing at least two viscous materials to be mixed. The dispenser contains an outer cartridge and an inner container. The cartridge has an open rear end having a rear thrust wall which will be pushed forward by the conventional dispensing gun. The cartridge has a front end containing a nozzle for connecting with a mixing nozzle. The container extends from the front end to the rear end and is made of telescoping sections. Viscous materials are present within the container and in the space between the wall of the container and the wall of the cartridge. As the rear thrust wall is pushed forward. the telescopic sections are captured in recesses of the rear thrust wall. More than one concentric container may be present.
Claims8
In a dispenser for viscous materials which should be kept separate until the time of application, the improvement wherein the dispenser comprises:
- a) a cartridge having i) a side wall having an inner surface and an outer surface, ii) a rearward end, iii) a forward end, the forward end having a closed periphery and an open central nozzle, iv) an open rearward end for receiving a piston of a dispensing gun, and v) a rear thrust wall which drives the contents of the dispenser forward as the thrust wall is forced forward by the piston, the thrust wall having a rearward surface, an outer side surface which fits flush with the inner surface of the cartridge, and a forward surface having at least one recess;
- and
- b) at least one container having i) a forward end having a neck which fits into the open central nozzle of the cartridge and a closed periphery;
- ii) a side wall having an inner surface, an outer surface, a rearward end, and a forward end, the container comprising multiple telescopic sections, the rearward end of the at least one container being in slidable contact with the at least one recess of the forward surface of the thrust wall such that the at least one recess captures the sectional wall of the at least one container as the thrust wall moves forward.
