Abstract: A mechanism for use with a syringe to permit repeated injections of various doses has a body in which is slidably mounted a syringe piston operating rod. A plunger surrounds part of the rod and is slidably mounted in the body, a releasable screw-threaded connection being formed between the plunger and the body. An automatic one-way ball clutch interconnects the plunger and rod, and a further one-way ball clutch interconnects the body and the rod. A dose is dispensed by rotating the plunger to thread that plunger away from the further one-way clutch until a required dose is displayed through a window, the rod being held stationary by the further one-way clutch. Then, on driving the plunger forwardly, the automatic one-way ball clutch connects the plunger to the rod, so that the rod is also driven to project further from the body. Movement is limited by the forward end of the plunger by striking a cup member secured in the body.

Abstract: An assembly for automatically injecting a fluid into the body is provided. The assembly includes a drive assembly, which can be reused many times, and a disposable assembly including a sleeve which contains a syringe. The drive assembly includes a housing having an open end to which a collar is mounted. The collar includes a radially inwardly extending pawl. The sleeve includes a generally cylindrical body having a radially outwardly extending rib. The rib defines a notch which is engageable with the pawl when the disposable assembly is inserted within the drive assembly housing. Engagement of the pawl within the notch prevents the disposable assembly from being ejected from the drive assembly housing should the actuating button of the drive assembly be pushed prematurely. Ejection of the disposable assembly requires its rotation with respect to the drive assembly housing to first disengage the pawl from the notch.

Abstract: A device for automatically injecting a material into the body is disclosed. The device includes a drive assembly and a syringe assembly which is mounted to the drive assembly. The drive assembly includes a drive rod, a driver releasably coupled to the drive rod, and a constant force spring which urges the drive rod towards the syringe assembly. The spring first urges the coupled drive rod and driver along the axis of the device, causing the skin to be penetrated by the needle of the syringe assembly. The drive rod is then decoupled from the driver. The spring continues to urge the drive rod in the axial direction, whereby the drive rod engages a piston in the syringe assembly and causes the displacement of the material therein.

A disposable liner (30) has a pair of handles (46) which can be looped around the legs (14) and has a main portion which can be draped over the seat portion (2) to define a collecting chamber. Following use the handles are knotted together and the liner (30) and contents are removed and disposed of and the legs (4, 16) can then be folded under the seat portion (2) for compact storage.

Abstract: A unit (3) for fitting on the open top of a container (1) made of cardboard, corrugated board or similar lightweight semi-rigid sheet material, said unit including securing means (10) arranged to be located and secured in an aperture (15) in a side wall of the container, spaced downwardly from the top thereof, to secure the unit to the container, the said securing means being arranged to extend through the said aperture and to protrude inwardly of the container wall, and being formed as a hollow element to define an outwardly opening but inwardly closed hand hole in the container wall, which hand hole is closed off from the container interior. In an alternative form the hand hole is not necessarily inwardly closed, but the securing member is locked in position.

Abstract: Dispensing containers are described in which a metering chamber for the contents of a fluid container is mounted in the neck of the container. Openings intermediate the height of the chamber allow it to be put in communication with the container interior by a rotary movement, e.g. applied to an external closure cap. When the closure cap is rotated to open the chamber to the container interior it also adopts a sealing position preventing the escape of any of the contents. The space in the chamber above the apertures is greater than that below. Sufficient fluid can be admitted to the chamber by inverting the container, therefore, to ensure that the lower space is completely filled when the container is again turned upright. Reverse rotation closes the openings to isolate the metered fluid from the main volume of the container and can also open the chamber to the exterior to allow the metered quantity to be dispensed.

Abstract: A dispensing valve unit for a gasified beverage, which unit (1) is adapted to be operatively connected both to a container (2) of gasified beverage and to a container (3) of gas for topping up the said beverage container with gas, and is so arranged as, when operated, both to dispense the beverage by gravity flow and to cause topping up gas from the gas container, regulated to substantially the same pressure as exists in the beverage container, to be supplied to the beverage container to replace the beverage dispensed therefrom.

Abstract: A cartridge assembly for a syringe-type medication dispensing unit includes a cartridge having a cartridge body with first and second ends. A pierceable membrane is mounted at the first end and a piston is mounted at the second end, with a volume of medication contained in the cartridge body between the membrane and the piston.
