A pool chemical injector includes a chamber to hold a volume of a chemical therein, the chamber having a body with a tapered end; an opening to allow for insertion of the chemical into the chamber; an elongated tube to attach to the tapered end of the body; a valve engaged with the tube and to open and close chemical flow through the elongated tube; and an attachment to secure to an end of the elongated tube through which the chemical flows; the elongated tube and attachment deliver the chemical to a floor of the pool.

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.

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.

An apparatus (10) for use in dispensing adhesive (18) is provided that has a mix applicator (12) that has a receiving portion (16) and a mix applicator bore (14) through which adhesive can flow. A mix head (20) is present that has a mix head bore (26) that extends through the mix head. The mix applicator is receivable within the mix head such that the receiving portion is located within the mix head. Adhesive can be dispensed in a ribbon shape from the mix head bore at a distal tip of the mix head. A lock member is configured for extending through at least a portion of the mix head, and engages the mix applicator when the receiving portion is located within the mix head in order to retain the mix head onto the mix applicator.

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 dosed by a cover. The insert is conical on a side facing the head part. A method can be used for producing such a cartridge.

A device for scraping caulk is adapted to be used with a caulk gun. The device includes a base plate having a central void and an elongated portion extending from the base plate along an axis perpendicular to the base plate. The device can be fitted between a caulk tube and a caulk gun to allow the application of caulk and the scraping/reshaping of the caulk in a single run. The device can include different replacement tips useful for different applications and different desired results.

Caulking systems and caulking system accessories are described herein.

An application system is presented having a cartridge, at least one first accessory part, for example a stopper, and at least one second accessory part, for example a static or dynamic mixer. The cartridge has at least one container with an outlet opening and at least one outlet connected to the container via the outlet opening on the end face of the cartridge, wherein the at least one outlet can be connected to the at least one first accessory part and the at least one second accessory part such that a seal is produced between the outlet and the respective accessory part. At least one separate seal plane is provided for each accessory part.

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.
