Abstract: A fluid dispensing gun for 1K-polyurethane foam includes a dispensing tube with a dosing nozzle at its outlet, a spring-loaded needle co-axially moveable in the dispensing tube for opening and closing the dosing nozzle, a trigger actuating the needle to open the nozzle and to dispense the fluid, a regulator regulating the degree of opening of the nozzle outlet and a coupler coupling a pressurized can to the gun. It also concerns a method for dispensing 1K-polyurethane foam. The fluid dispensing gun includes a delivery device delivering a curing fluid essentially parallel to the nozzle outlet that includes a curing fluid reservoir, a curing fluid outlet situated near the nozzle and a curing fluid line connecting the curing fluid reservoir and the curing fluid outlet, the trigger activating the delivery device. The curing fluid delivered in the same direction as the 1K-polyurethane foam and separately therefrom makes the foam cure more rapidly.

Abstract: A stem of a valve for a container for dispensing pressurized fluid, has an inner channel inside a cylindrical housing connecting the at least one lateral inlet opening at its lower end and an outlet opening at its upper end. The inner channel has a conical shape at its lower end and the diameter of the cylindrical housing is increased towards the lower end of the stem and in particular in the section which corresponds to the section with lateral inlet openings. Both adaptations reinforce the stem and make it more resilient against bending and tensile forces.

Abstract: 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.

The lower end of the stem is ball-shaped and forms a ball joint with a correspondingly ball-shaped ball socket being part of the housing, wherein the upper part of the housing is provided with sealing means and the stem is tiltable between a closed position and an open position.

Abstract: A basket for securing a container to a dispenser has a device for connecting the basket with the dispenser and a device for connecting the basket with the container and a cylindrical seat for a valve of the container, wherein the basket provides a fluid connection between the container and the dispenser, wherein the basket provides a grip area for mounting the basket on the dispenser. The grip area is located on the cylindrical seat. The location of the grip area on the cylindrical seat reduces the height of the basket and improves the handling of the dispenser.

Abstract: The invention concerns a caulking gun for dispensing material comprising a stock, a cartridge keep, a push rod longitudinally moveably mounted in the stock provided at its one end with a plunger which engages the piston of a cartridge placed in the cartridge keep, a catch member placed on the push rod, a trigger coupled to the catch member via an axle and pivoting about a pivot point, means for varying the thrust output exerted on the push rod when pressing the trigger for a given strength exerted on the trigger, wherein the means for modifying the thrust output allow the displacement of the axle between at least a first position and a second position.

Abstract: 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.

Abstract: A caulking gun for dispensing viscous material does not have any freeloop. A brake device is in the first and in the second position inclined relative to the axis of the push rod and a release device pushes the brake device in a third, essentially perpendicular position relative to the axis of the push rod in order to disengage the push rod from the brake device for pulling back the push rod and for acting simultaneously on the push device in order to disengage the push rod. Because the brake device is inclined in the first and in the second position due to the action of a spring acting on one end of the brake device and clamps the rod so that any freeloop (because the brake device does not clamp the rod in the upright position) is avoided.

Abstract: A valve for a fluid dispensing container includes a mounting cup to be fixed on a container, a housing to be fixed on the mounting cup and defining a channel with an inlet end and an outlet end, whereby a hollow stem is glidingly arranged in the channel. The stem is flange-free and a concentric circumferential conical sealing protrusion on the stem forms the sealing between the outer surface of the stem and the housing. When the stem passes from the open into the closed position, it enters at least partially into the housing without product being retained between the flange of the stem and the housing.

Abstract: The present invention relates to a valve member for a dispenser valve for foam products, and in particular for a dispenser valve for polyurethane foam container, comprising a valve member that is moveable relative to a sealing. It also relates to such a dispenser valve and to a foam container. In order to provide alternative materials for valve members, it is proposed according to the invention that the valve member is made of plastic material filled with basalt particles in an amount between 1% and 60% by weight. It has been surprisingly found that valve members made of plastic filled with basalt particles in these amounts show improved properties, such as strength and abrasion rates, compared to non-filled plastics and compared to glass-filled plastics.
