Abstract: A dispenser for viscous, extrudable materials uses a sprocket-driven push chain that is drawn from a chain magazine responsive to actuation of a user trigger. The sprocket for the chain is driven by a toothed wheel, which is driven by a first, ratcheting drive pawl, which is actuated by the trigger. A second ratcheting locking pawl prevents the toothed wheel and hence the chain sprocket from rotating backward when the trigger is released. A single “button” or actuator can be actuated by one hand of a user while the user's other hand grasps a chain retractor to pull an extended chain back to a starting position whereat the dispenser can be reloaded.

The actuator comprises precisely repeatable positions and is calibrated according to the invention by measuring the sizes of the dosages produced by the movements between the positions. The dosing is effected after that by selectively repealing the calibrated movements.

Abstract: To avoid the use of propellants which are harmful to the environment, a spraying apparatus employs a supply chamber which contains a material to be sprayed and includes a pressure chamber of variable volume. This pressure chamber of variable volume is connected to actuating structure which is provided for increasing the volume of the pressure chamber and thus for sucking material from the supply chamber into the pressure chamber. Since the material within the pressure chamber is kept under pressure by pressurizing structure, a nonreturn valve is disposed in the suction conduit leading to the supply chamber. Material can be sprayed with the aid of the spraying apparatus without any harmful effects on the environment, the use of conventional spraying heads being here possible.

The cartridge is supported on top of a main pressure cylinder adapted for controlled connection to a pressurized fluid source, such as compressed air, for displacing a power piston in a first direction. The power piston is connected to a pair of flexible piston rods which extend through curved guide channels in a guide head and are connected in turn to a pair of piston plungers receivable into the cartridge barrels to dispense the dual components.

Abstract: The present invention is directed toward a material dispensing container that uses a flexible band to drive a piston within a storage container. The band is so formed so that it can be easily wound or folded within a small area at the bottom of the storage container. The band is connected to a piston within the container, and the movement of the band forces materials stored above the piston to be dispensed through any dispensing orifice at the top of the container. The band drives the piston by being forced through a tapered conduit. The passage of the band through the conduit, orients the band and causes the band to loose some of its flexibility. The stiffened band is then used to drive the piston. The passage of the band through the tapered conduit also orients the band so that extensions, stemming from the band, can be engaged and forwardly advanced by the user.

Abstract: A dispenser gun having a hollow tubular body member for receiving a cartridge of flowable material therein, and a removable cap member to maintain the cartridge within the body member so that a nozzle of the cartridge extends through an opening in the cap member. The body member includes a trigger mechanism for acting upon a cam retaining mechanism to disengage a cable into a released position to allow a spring biased pressure disc, which is connected to the cable, to act upon the cartridge to dispense or discharge the flowable material therefrom. In the non-discharging position, the cam retaining mechanism engages the cable in a locked position so that the cable prevents any forward movement of the pressure disc against the cartridge. The cartridge can be of either the disposable type or the reusable type, where a liquid impermeable insert bag can be inserted within the reusable type cartridge.

Abstract: The present invention relates to a strap dispenser formed from a tubular container with a product outlet. Within a chamber defined by the container is a piston intregally formed with a strap which advances the piston toward the outlet to dispense material in the chamber. The strap extends toward the outlet within the chamber but passes through an opening outside of the chamber and into a slot formed in the container's periphery. It is the portion of the strap extending outside the chamber that enables actuation of the piston. The opening is defined by a guide around which the strap bends as it moves toward the opening and a wiper which with the guide removes material from the strap. The piston may be formed from a plurality of ribs each having a cutout to pass around the container surface which defines the slot. The smooth surface of the slot and the strap enables the entire contents of the chamber to be quickly dispensed at one time.
