A foam transfer or dispensing device is described which dispenses foam from a source of foam, typically a pressurised canister, and which enables efficient purging or air and an initial volume of foam from the device to ensure foam sterility and quality when a syringe is filled from the device. The device comprises a foam inlet arranged for communication with a source of foam, a foam pathway in fluid communication with the foam inlet and comprising a foam outlet, arranged for engagement by a syringe nozzle; and a waste outlet in fluid communication with the foam pathway. The foam pathway comprises a tubular projection arranged to extend through the foam outlet and into a syringe nozzle when a syringe is connected to the foam outlet, which improves the efficiency of the purging process and prevents pooling of air or foam. The device further comprises a means for restricting displacement of material through the waste outlet, so that the user can control the volume of foam that is wasted.

A pressurized dispensing system including a plastic bottle and a method of minimizing the formation of stress cracks in a plastic bottle that is a part of a pressurized dispensing system. In a method of manufacturing the pressurized dispensing system, a plastic bottle is filled with a liquid, a valve is crimped onto the plastic bottle, and the plastic bottle is filled with gas so as to pressurize the plastic bottle. The plastic bottle is supported only in the finish region throughout the liquid filling, valve crimping, and gas filling steps. The filled and pressurized plastic bottle is substantially free of stress cracks.

A dispensing device adapted for placement within a bathroom adjacent to a toilet to generally dispense an aerosolized fluid from within a fluid container and onto the surface of water within the toilet. The fluid is provided with a density less than water, wherein the fluid is provided to form a barrier on the surface of the water. The dispensing device including a sensor, indicator, trigger mechanism and stirring means adapted to stir the fluid within the fluid container.

An aerosol delivery device is provided that includes at least one housing enclosing a reservoir configured to retain an aerosol precursor composition and a heating element controllable to activate and vaporize components of the aerosol precursor composition. The aerosol delivery device also includes an antenna configured to receive radio signals from satellites of a satellite navigation system, and convert the radio signals to corresponding electronic signals and a satellite navigation receiver module configured to receive the corresponding electronic signals and determine a position of the aerosol delivery device based thereon, and output a message that indicates the position so determined. And the aerosol delivery device includes a microprocessor configured to receive the message and control operation of at least one functional element of the aerosol delivery device based on the position indicated thereby.

A pressure pack dispenser (100) for dispensing a product comprises a cylindrical container (401) with a product outlet through which the product is dispensed, a composite piston (408) movably mounted within the container, and a pressurised propellant. The composite piston comprises a first upper piston (409A) coupled to a second lower piston (409B) to permit limited relative axial movement and a viscous sealant material (410) located between the first and second pistons. The propellant comprises a compressed gas which remains in the gaseous phase as the piston (408) moves from a first full position to a second exhausted position, or a mixture of a liquid propellant and a compressed gas selected such that in the full position the mixture is at a pressure greater than the vapour pressure of the liquid propellant. A clearance is provided between the second lower piston (409B) and the container wall (401A) which is filled with the sealant (410) as the composite piston moves to expel product. The viscosity of the sealant and clearance are selected such that a thin film of viscous sealant material (410A) is left on the container wall of the propellant chamber, thereby reducing friction between the composite piston (408) and the container wall (401A). The sealant (410) preferably comprises a mixture of glycerine and starch, and has a viscosity of less than 100 poise and less than 4000 poise at 20° C.

An apparatus is provided that is configured to be used with a container having contents to permit mixing of the contents of the container. The apparatus includes a main body having a geometrical shape having an open end, a closed end, and a longitudinally extending bore or opening extending from the open end to the closed end. The opening or bore is configured to receive at least a portion of a container. A shaft is generally orthogonally positioned from a portion of the closed end. The shaft is configured to be received by a rotational device. The mixing apparatus can be used to mix various sized containers containing contents having one or more materials to be mixed. The container is not attached to any portion of the main body and the container is configured to rotate freely and independently of the main body during an operation of the rotational device.

An inhalation device including a housing, which encloses a liquid reservoir in which the liquid is stored before discharge, and an applicator head with a nebulization chamber and an applicator piece connected thereto, wherein the applicator piece is designed either as a mouthpiece, to be received in the mouth of a patient, or as an inhalation mask, to sealingly cover the mouth, the nose, or the mouth and the nose. The inhalation device furthermore has a discharge channel which connects the liquid reservoir to the applicator head.
