The external wall of the second cartridge touches against the internal wall of the first cartridge and is attached to the internal wall of the first cartridge, whereby the second cartridge contains a second starting component and has a second dispensing plunger arranged in it, whereby a pressing device with a clamping edge for compressing the second cartridge that can be propelled axially in the internal space of the first cartridge is arranged, as seen from the cartridge head, behind the first dispensing plunger and the second dispensing plunger. The pressing device can be propelled appropriately in the direction of the cartridge head such that the second cartridge is being progressively compressed axially during the motion of the pressing device such that, in the process, the first dispensing plunger and the second dispensing plunger are propelled in the direction of the cartridge head.

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.

A polyurethane composition raw material liquid agent filled in a cartridge-like container comprises a polyol or a polyisocyanate, and a filler, wherein the polyurethane composition raw material liquid agent has a viscosity at 25° C. and a rotation speed of 10 rpm of 2300 mPa.Math.s or more. The filler may include a solid flame retardant. The polyurethane composition raw material liquid agent and another polyurethane composition raw material liquid agent are mixed and discharged to form a polyurethane composition.

A dispensing apparatus simultaneous discharges at least two flowable components of a multi-component mass from different storage volumes. The dispensing apparatus includes a passive mixing unit having a central mixing passage extending along a flow direction and being configured to guide the components mixed with one another, and including at least two inlets opening into the central mixing passage, the inlets being associated with the same storage volume and open into the mixing passage at different positions along the flow direction.

A push member and a caulking gun having the same. The caulking gun includes the push member, a gun body and a push rod. The push member includes a blockable receiving portion which includes a receiving space and a lip protruding from a periphery of the receiving space, and a push portion arranged opposite to the blockable receiving portion in a first direction, for pushing a caulk cartridge. The lip defines a blocking mouth, and the blocking mouth and the receiving space are open toward a same lateral side of the push member to form an open end. When a push plate of the push rod is disposed within the receiving space, the lip and the push plate are blockable with each other in the first direction.

A dispenser actuator assembly (100) has base member (102) and an actuator arm (104) that is configured to crush a glass ampoule assembly (10). The glass ampoule assembly (10) has a rupturable glass ampoule (12) containing a flowable material (M). The glass ampoule (12) is contained within an outer container (14), the outer container (14) having a first open end (22) and a second closed end (24). The glass ampoule assembly (10) has an applicator (16) positioned in the first open end (22). The dispenser actuator assembly (100) has the base member (102) that is configured to mount on the outer container (14). The actuator arm (104) is pivotally connected to the base member (102). The actuator arm (104) is pivotable from a first position to a second position that is configured to engage the outer container (14) to crush the glass ampoule (12) wherein the flowable material (M) is dispensed from the glass ampoule assembly (10).

A dispenser (10) for dispensing a flowable material M has a container (12) having an outer wall (20) and membrane (14) collectively defining a first chamber (22) configured to contain the flowable material M. The membrane (14) has a thickness and a weld seam (40) wherein the weld seam (40) has a thickness less than the thickness of the membrane (14). A fracturing mechanism (16) is operably connected to the container (12). The fracturing mechanism (16) has an extending member (64) projecting from the outer wall (20) of the container (12). The extending member (64) has a projection (66) positioned proximate the membrane (14), wherein in response to deflection of the extending member (64), the projection (66) deflects the outer wall (20) proximate the membrane (14) wherein the weld seam (40) fractures creating an opening (41) through the membrane (14) configured to allow the flowable material M to pass therethrough and from the dispenser (10).

A roll-up grout bag apparatus includes a dowel with a slot formed therethrough from an open end to a closed end thereof. A lever is engaged with the dowel at the closed end to facilitate rolling the dowel about an axis thereof. The slot receives a filling end of a grout bag and is rolled onto the dowel using the lever to urge grout within the bag to be dispensed from an opening at a narrow dispensing end of the bag. The apparatus may include a ratchet mechanism to engage the lever with the dowel.
