FIELD: cartridges.
SUBSTANCE: invention relates to cartridges for containing and extruding plastic viscous materials such as sealants, greases, adhesives. Cartridge for plastic viscous materials according to option 1 includes a cylindrical body with the first open end closed by a fixed and hermetically sealed cap, and also with a second open end closed by a hermetically sealed piston cap; at the first end of the housing from the outside, a protruding section is formed, designed to install the cover on its end surface; on the inside of the body, said protruding section is made with a bent edge triangular in cross-section, designed to fix the cover on the body and tightly connect the cover and body. The side surface of the lid is made with a thickening designed for tight connection of the lid to the body. At the second end of the housing, from the outside, its wall is made with external relief bulges, and the inner side of the housing wall is made with internal relief bulges with the possibility of fixing and tight connection of the piston cover and housing; The piston cap has a cylindrical shape, made with double walls - inner and outer, connected to the outer end of the piston cap by a horizontal wall, and the outer wall is a detachable annular element and is connected to the inner wall by a section with reduced resistance. The cartridge according to option 2 includes a piston cover made with double walls - inner and outer, connected by a horizontal wall, while the inner wall is connected to a persistent horizontal wall.
EFFECT: expanding the arsenal of cartridges for plastic viscous materials, increasing the tightness of the cartridge.
