In opposite side walls the channel-shaped section 23 is provided with slots 3B having rack teeth 36 to accommodate the operating cogs or pinions 31 mounted on opposite end portions of the axle of the compressing roller 31. A suitable knob or operating element 33 is provided on the same axle to turn the roller to express the contents of the tube in an evident manner.

In practice, special cartridges or tubes are manufactured and sold to t in the particular holder 25. 'I'he sections of the holder can be spread open tor allow the tube to be inserted. By completely spreading the sections 26 and 29 the bayonet slot and pin means is readily usable to adjoin the tube 2i to the adapter tting or neck 24. At the same time, under this arrangement the puncturable diaphragm can be readily broken to permit the contents to now, when pressed. through the intake or delivery nozzle Il.

It is obvious that the compressible tube is squeezed or pressed through the instrumentality of the shiftable compressing roller 31. Thus it will be easy for the' user to insert and remove the component parts for expeditious use. Then too, the final discharge of the paste through the ports I3 can be fully regulated by the aforementioned plate valve i4.

It is thought that the description taken in connection with the drawings will enable a clear understanding of the invention to be had. Therefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the eld of invention claimed may be resorted to if desired.

What I claim is:
