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.

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.

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.

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.

An interface ring which is the interface between a container and an applicator comprising a circular socket with a plurality of laterally extending protrusions, a cylindrical thread being arranged above the socket, a central cylindrical opening extending through the interface ring in the centre of the thread and the socket wherein the thread presents a plurality of interruptions extending axially from the socket to the upper end of the thread, the interruptions dividing the thread into thread portions. It is an object of the present invention to provide an optimized interface ring. In order to achieve this object, the interface ring comprises deformable vertical ribs laterally extending mostly parallel to the radial axis of the interface ring wherein the deformable ribs deform when the interface ring is mounted on the outer rim of the cup of a valve or by other means on to the container. An interface ring with an increased grip of the interface ring on the valve. Therefore, much higher turning and buckling forces can be reached.

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.

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.

A mounting assembly for mounting an adapter to a valve stem of a valve of a pressurized container for the application of foam, where the adapter is configured to be mounted by means of the female threaded element onto the male threaded element of the valve stem by means of an axial screwing movement up to the mounted position, wherein the adapter further comprises a locking element at the extreme upstream end that is configured, when mounting, under the effect of the axial screwing movement towards the mounted position, to move past the collar and secure the female threaded element in the mounted position.

The present invention relates to a caulking gun for dispensing viscous material comprising In order to provide an adjustable caulking gun with at least two different levels of retreat of the push rod giving the user easily a visual feedback of the chosen retreat of the push rod, it is proposed according to the present invention that the adjusting means are configured as a rotatable wheel with a slope, the rotatable wheel being positioned on the axis of the push rod between the stock and the brake means, the distance between the highest point of the slope and the brake means defining the retreat of the push rod. This rotatable wheel allows the user to select the level of retreat of the push rod by turning the wheel between a first position with no retreat of the push rod and a second position with a maximum retreat of the push rod resulting in a anti-drip behavior of the caulking gun.

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.
