In one aspect, the invention provides a fluid dispenser comprising a housing configured to receive a means for pressurizing and a disposable fluid bag, and a nozzle towards a distal end. A means for flow control comprising a tubular body whose longitudinal axis coincides with the longitudinal axis of the nozzle having a diameter that tapers from the side distal to the nozzle towards the nozzle is provided. The tubular body is configured to move along its longitudinal axis such that a volume of a gap between the tubular body and the nozzle is varied thus controlling the flow rate. Further, an adapter configured to be fitted onto the nozzle capable of receiving at least one applicator is provided. The fluid dispenser of the invention is capable of being used in a variety of situations in a facile manner, replacing several different devices to be used for individual applications.

The present invention is in the field of an improved method of applying a two-component adhesive, wherein the adhesive is provided packaged in a foil, typically one and the same foil, a package comprising said adhesive and an adapted sealing gun, said adapted sealing gun, and specific uses of said package and sealing gun.

A flowable material dispenser including a barrel defining a cylindrical interior volume for holding a flexible material bag containing a flowable material. A nozzle is attached to the first end of the barrel for discharging the flowable material through a nozzle hole; and a closure is disposed on the second end. A center nut disposed on the closure holds a threaded drive rod threadably and rotatably inserted in the center nut. The drive rod includes an inner end and an outer end. Drive structure for imparting rotational forces to the drive rod moves the drive rod reciprocally and axially within the cylindrical interior volume of the barrel to twist and wring out flowable material contained within the flexible material bag.

A cartridge for a dispensing device contains at least one elongate film pouch, which is inherently non-rigid and which has a chamber for receiving a composition. The cartridge also contains a head part for interacting with the film pouch. The film pouch has an opening on a side facing the head part, which is closed by a cover. The cover has a predetermined breaking region. A method can be used for producing such a cartridge.

A reusable cartridge piston for use with film bag cartridges comprises a piston base, an intermediate portion and a piston head. An extension axis extends from the piston base through the intermediate portion and through the piston head. The piston also includes a lip sections extending radially outwardly with respect to the extension axis from a sidewall of the piston head, the piston base and the piston head being spaced apart from one another by the intermediate portion, with a gap between the piston base and the lip sections. The lip sections are respectively spaced apart from one another by slits formed between two neighboring lip sections, with the slits extending in a radial direction with respect to the extension axis of the piston. The piston base, the intermediate portion, the piston head and the lip sections are formed as one piece.

A surface repair tool for repairing defects in surfaces includes a handle with an applicator blade extending from one end of the handle and a sanding device extending from the opposite end of the handle. The handle includes a receptacle into which is removably received a container of repair compound. The applicator blade includes an application surface and a flow passage that has an inlet and an orifice formed through the application surface. Squeezing the container causes repair compound in the container to flow through the flow passage of the applicator blade and out of the orifice where it is dispensed onto the applicator surface to be spread on a surface needing repair. Once the repair compound dries, the sanding device is used to sand the repair compound to a desire finish.

A cartridge for a dispensing device has at least one inherently non-rigid, elongate film pouch, which has a chamber for receiving a composition. The cartridge also has a head part for interacting with the film pouch. The head part has an inherently rigid insert, which is connected to the film pouch on a side facing the head part. A connecting device is provided, which can connect the insert to the head part in a form-fitting and/or force-fitting manner. The insert has at least one first connecting element of the connecting device and the head part has at least one second connecting element of the connecting device.

A reversible and reusable caulk dispenser for use with a caulk gun. The caulk dispenser has a tubular cartridge with a plunger inside the cartridge near a first open end of the cartridge and an end cap with a nozzle that can be attached at an open second end of the cartridge. A foil packet of caulk or sealant material is inserted in the cartridge of the dispenser. A closed end of the packet is positioned adjacent the plunger while an open end of the packet is at the end of the cartridge where the end cap is attached. The dispenser is used in a standard caulk gun and the caulk material expelled through the nozzle as the caulk gun is operated. When the packet is emptied the dispenser can be reused with a new packet inserted and the end cap attached now to the opposite end of the cartridge.

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).

One example of the present disclosure relates to a daubing device for applying viscous material to a fastener. The daubing device comprises a housing comprising a first internal face and a second internal face, separated from the first internal face by a longitudinal distance L. The daubing device further comprises a dispenser between the first internal face and the second internal face of the housing. The dispenser comprises a flexible wall. The daubing device also comprises a pressure-application device between the dispenser and the second internal face of the housing.
