The present invention provides a plunger (20) for a dispenser, the plunger including a large diameter body portion (23) provided with ring-shaped contact surfaces (24, 25) that contact an inner wall surface of a syringe, a rear opening (26) formed in a backside of the large diameter body portion (23), and a small diameter body portion (22) provided with a front opening (28), wherein the front opening (28) is formed in a size allowing a liquid material to be directly pressed by pressurized air, and allowing at least the plunger (20) to move following a fall in water head position, which is caused with discharge and consumption of the liquid material. With those features, the liquid material can be prevented from adhering to the inner wall surface of the syringe, and the liquid material in the syringe can be prevented from flowing backwards.

A caulk storage system for storing an opened calk container includes a calk container that has a tube and a spout. The calk container may contain a fluid calk. A pair of cylinders is provided. The cylinders are matable to each other to define a closed tube. The calk container is positioned in each of the cylinders when the cylinders are mated together. Thus, the pair of cylinders inhibits the fluid calk from drying thereby facilitating the calk container to be stored when the calk container is opened.

The disclosure relates to an adapter piece for an application device for multicomponent materials, including multicomponent adhesives or multicomponent sealants. The application device has at least one first cartridge receiving device for receiving a first replaceable cartridge containing a first material component, at least one second cartridge receiving device for receiving a second replaceable cartridge containing a second material component, at least one discharging device for discharging the material components out of the cartridges through cartridge outlets, and at least one mixing device for mixing and discharging the material components. A second cartridge receiving area includes a relief chamber such that a material component exiting the second cartridge first fills the relief chamber before entering the mixing device.

There is provided an applied liquid applicator for discharging applied liquid by turning of an operating portion provided to a barrel main body, in which filling efficiency of the applied liquid stored in the barrel main body with respect to an inside capacity of the barrel main body is improved. The applied liquid is fed to the applicator portion through the first valve and the applied liquid feed path by turning the operating portion and sliding the piston in the front-back direction by use of the cam mechanism portion.

A method of making a two-component piston, the two-component piston including a piston cover as the first component and a piston body as the second component. The piston cover is arranged adjacent to the piston body and is configured to be moved relative to the piston body.

A caulking gun includes a carrier for carrying a caulk cartridge, an assembly for the carrier, a gun body and a push rod. The assembly is for disposing between the gun body and the carrier and includes a seat portion and a spacing portion. The seat portion includes a seat wall for being connected between the gun body and the carrier. The spacing portion includes an annular projection portion configured to be abutted between the gun body and the carrier in a manner that the gun body and the carrier are rotatable relative to each other. The carrier is rotatably connected with the gun body through the assembly, and the carrier is rotatable relative to the annular projection portion. The push rod is movably connected to the gun body and disposed through the assembly, and extends into the carrier.

The present invention relates to a mixer and applicator device for mixing and applying a compound obtained by means of mixing two products which comprises: a casing which internally houses a movable push rod, where the casing allows housing a container which is fixed to the casing, a drill or rotor for driving the movable push rod, a base part coupled to a rear portion of the drill or rotor, at least one guide which is secured at a first end on the base part and at a second end on the casing where the ends of the at least one guide are fixed on the casing such that the at least one guide allows the fixing and rotation of the casing, and at least one member going through the at least one guide respectively such that the rotation of the casing does not take place in response to the actuation of the drill or rotor. As a result of this device it is possible, using the same device, to prepare a compound by means of mixing a base product and a catalyst and to further be able to dispense it without having to perform any disassembly or adaptation whatsoever in the container or in the means used for the mixing.

A caulking gun is provided, including: a gun body, including a main body, a push mechanism, a driving member movably disposed within the main body and a lever rotatably mounted to the main body to drive the driving member, the push mechanism including a restriction member swingably disposed on the main body and a push rod movably disposed on the main body and disposed through the restriction member; and an adjustment mechanism, mounted to the gun body, being movable to be located in a first position or at least two different other positions; wherein when the adjustment mechanism is located in the first position, the adjustment mechanism contacts the restriction member or the driving member; the adjustment mechanism is distanced by different distances from the restriction member or from the driving member when the adjustment mechanism is located in the at least two different other positions.

The present invention relates to a system of converting dispensing packs with two or more compartments with a fixed volume to modified ratio dispensing packs or dispensing packs with one compartment to multiple compartment dispensing packs using modified compressible foam or fibre inserts.

Provided is a multi-layer self-adhesive gel suitable for use in cleaning, disinfecting, deodorizing, and/or scenting of toilets, sinks, wash-bowls, bathtubs, showers, and for delivery of shower gel or shampoo in the shower, bathtub or wash-bowl. The multi-layer self-adhesive gel has at least two different self-adhesive gel layers. One gel layer (A) includes at least one solvent (a1), at least one adhesion promoter (b1) which is different from (a1), and at least one surfactant (c1) which is different from (a1) and (b1). Another gel layer (B) includes at least one solvent (a2), at least one adhesion promoter (b2) which is different from (a2). When the multi-layer self-adhesive gel is applied onto a flat surface of a substrate, (A) and (B) together have a continuous, essentially even surface, remote from the surface of the substrate. Also provided are an applicator containing the multi-layer self-adhesive gel and methods of filling the applicator.
