Abstract: Dispensers for pasty compositions having a housing (1) with a piston (2) which is displaceable only in the emptying direction and an actuating handle (H) which is developed on a head piece (5) which can be pressed bellows-like in the direction towards the piston (2) and has a dispenser outlet opening (O) from which there extends, directed inwards, a tube (7) whose inner mouth-end (7") dips freely into the pasty composition in every position of the bellows (B). A structural shape which is simple to manufacture and nevertheless dependable in operation, comprises a flap valve (9) with passage opening lying in the direction of the tube (7) (arrow z), below the inner mouth-end (7") of the tube (7), in the cover (8) of the housing (1) from which a mounting collar (6) for the bellows (B) extends.

Abstract: There is provided a dispenser for paste material, such as tooth paste, having a movable piston disposed in the dispenser casing below the paste material adapted to move in the direction of the nozzle opening and prevented from moving in the opposite direction by a first locking mechanism, and a push button for the displacement of an upper pressure cover which is disposed inside the dispenser casing above the material and which is coupled with the piston through a rod which penetrates and is force locked with the piston by means of a second locking mechanism working opposite to the first locking mechanism. A guide piece is provided which is connected with the rod and the pressure cover and extends above the pressure cover, passing through a guide opening in the casing top surmounting the pressure cover. The guide piece is connected to the push button mounted in the casing top.

Abstract: A dispenser is provided for dispensing unit doses of a substance, such as tablets, pastes and the like having a tubular casing with a discharge opening at one end and a pressure bottom at the other end for the displacement of the discharge substance in the direction of the discharge opening, the pressure bottom being moved step by step in the direction of the discharge opening by the action of an operating handle positioned near the discharge opening and of at least one transport rack, the pressure bottom being blocked against backwards movement by at least one support rack located at the inner wall of the tubular casing, the transport rack and the support rack being mounted on an insert piece of the tube casing.

Abstract: A dispenser for the individual portioned dispensing of tablets (1), pastes or the like, having a housing pipe (2) which is provided at one end with a delivery opening (6) and, opposite same, is equipped with a push bottom (13) for transporting of the material to be dispensed in the direction towards the delivery opening (6), which push bottom (13) can be displaced stepwise in the direction towards the delivery opening by means of an actuating handle which is adjacent the delivery opening and is connected to the push bottom. In order to obtain a favorable accommodation for the material to the dispensed, the bar connection between actuating handle (9) and push bottom (13) extends along the inner surface of the housing pipe wall, leaving the inside of the housing pipe (2) free.

Abstract: A dispenser for pasty compositions (M) having a housing (1) in which there is arranged a piston (2) which is displaceable only in the emptying direction. An outer actuating handle is provided on a wall (10) of the head piece (K). The wall can be pressed in the direction towards the piston, the head piece having a dispenser outlet opening (7) which lies at the outer end (9") of a tube (9) whose end section (9') forms an inner open mouth end the end section over its entire length protruding inwards beyond the wall into the pasty composition. In order to obtain a structural shape which is simple to manufacture and a self-regulation of the delivery which is free of loss the actuating handle is formed as a dome-shaped cap (6) and is seated on a collar (12) which lies concentric to the tube (9) and which collar protrudes outwardly beyond the wall (10). A removable closure lid has a stopper which extends into the dispenser outlet opening.

Abstract: A dispenser for flowable substances with an elastically resilient squeeze head arranged on a dispenser housing has a valve nozzle-opening. A suction tube extends from the bottom of the squeeze head down to the bottom of the dispenser housing, the tube having an opening communicating with the interior of the squeeze head, and a non-return valve for closing the opening.

Abstract: The present invention relates to a dispenser for pasty compositions having a bellows on the top, a piston which travels in the direction towards the nozzle, and a rod which connects the bellows to the piston in such a manner that there is an idle stroke between piston rod and bellows so that a certain quantity of the content of the container withdraws into the nozzle channel upon release of the bellows.
