To permit a portionwise or continuous delivery of the filled material, the container is provided on its guide poart with an axially parallel, downwardly open slot corresponding to the total stroke of the piston and a double-walled slide is provided for the displacement of the piston and which roughly corresponds to the slot length and whose two walls engage on the container wall externally or internally on either side of the slot and whose inner wall is connected at its upper end to the piston and at the lower end to the outer wall.

Abstract: A counter display package for dispensing small articles comprises a generally rectangular carton containing a drawer which forms a bottom portion of the carton. A tear-away panel in the front wall of the carton is removed to expose a drawer opening through which the drawer is pulled from a closed to an open position. A chute wall hingedly connected to the drawer extends a substantial distance above the drawer and is disposed within the carton and generally adjacent the rear wall of the carton when the drawer is closed. The chute panel is retained in the latter position by loosely packed small articles contained within the carton. When the drawer is opened the chute panel assumes a position wherein it is forwardly and downwardly inclined from the carton rear wall to the drawer. The inclined chute wall cooperates with portions of the carton front and side walls to form a hopper for directing small articles from the upper portion of the carton into the drawer.

Abstract: An oil metering apparatus is disclosed which will provide a ready supply of oil to a vehicle whenever necessary. The apparatus includes an oil reservoir and adjustable outlet structure which is positionable in the reservoir to release oil from the reservoir. Metering structure is preferably provided to measure the amount of oil that is released. Tube structure transfers oil released through the outlet structure directly to the engine. Locking structure can be provided to retain the outlet at a selected position within the reservoir. Structure can also be provided to suspend the apparatus from the hood of the vehicle.

Abstract: Apparatus for administering medical liquids comprising a combination of a calibrated flexible bag and a liquid level indicating device for increasing the accuracy of measuring the level of liquids within the bag. The liquid level indicating device consists of a pair of spaced-apart elongated rollers which form a slot into which the upper part of the bag can be inserted. The rollers rest on the outside of the bag at about the upper level of liquid within the bag.

Abstract: An improved dispenser for the contents of collapsible tubes is provided in which a pair of opposing squeezers are advanced along two opposing pairs of externally threaded rods within a housing. The squeezers are made of a flexible material such as semi-rigid rubber and are configured such that one end of each squeezer is longitudinally displaced towards the dispensing aperture in the housing and transversely displaced towards the sidewall of the housing. This arrangement causes the squeezers to deform and change profile when the leading edges of the advancing squeezers are stopped prior to the following edges being stopped. The deformation of the squeezers more effectively places pressure on the collapsible tube near the dispensing aperture of the tube and substantially completely dispenses the contents of the tube.

Abstract: Apparatus for the parenteral fluid administration to a patient including a pressure applying piston to apply pressure to a flexible bag containing the parenteral fluid. The piston has an indicator to indicate its movement and stop devices are provided which can be adjustably positioned to give the piston a predetermined movement to dispense a predetermined quantity of fluid.

Abstract: A rotary power hand tool with a rotary chuck is mated to a push-in piston-type dispensing container of caulking via an adapter which mounts on the tool and is secured to the chuck. The adapter has a plunger provided on the end of a non-rotating screw. When the tool trigger is actuated, a transmission on the actuator is operated to advance the screw and plunger thus advancing the piston of the dispensing container. In the preferred embodiment a peg secured to the drive screw and protruding out of the adapter doubles as a way of preventing the drive screw from rotating and as a way to indicate the relative amount of contents remaining to be dispensed until the container is effectively empty.
