A caulking gun for dispensing material includes a stock, a cartridge keep, a push rod longitudinally moveably mounted in the stock with one end having a plunger engaging a cartridge piston in the cartridge keep, a catch on the rod, a trigger coupled to the catch via an axle and pivoting about a pivot point, and a device for varying thrust output exerted on the rod when pressing the trigger for a given strength exerted on the trigger that allows axle displacement between at least first and second positions. The trigger has an upper part with a trigger bridge with two long holes. The thrust output varying device includes a ratio bridge element put over the trigger bridge and trigger and linked to the trigger bridge via the axle traversing the holes. By displacing the axle either between fixed values or continuously and the thrust output can be varied between fixed values or continuously.

A valve for a container for dispensing pressurized fluid includes a housing which is mounted on a valve cup, a hollow stem provided in a passage of the housing which stem has at least one lateral inlet opening at its lower end and an outlet opening at its upper end, and a spring. The housing has a circumferential step-like contour with an outer, lower part and a central, upper part. The valve cup follows essentially the step-like contour line of the housing and ends horizontally on the top of the housing close to the stem and a sealing is provided on the upper side of the housing between the housing and the valve cup and which seals at the same time the valve cup against the housing and the stem against the housing.
