Abstract

A kit includes a refillable dispenser that is propellant-free and a filling device that is pressurized and propellant-free. An outlet of the filling device is configured to disengageably connect to an inlet of the refillable dispenser, and wherein connection between the inlet and the outlet establishes fluid communication between the filling device and the refillable dispenser and generates a unidirectional flow of material from the filling device to the refillable dispenser.

IPC Classes  ?

• B05B 11/00 - Single-unit hand-held apparatus in which flow of contents is produced by the muscular force of the operator at the moment of use
• B05B 11/02 - Membranes or pistons acting on the contents inside the container, e.g. follower pistons

Abstract

A Propellant-Free continuous dispenser for dispensing liquid or viscous materials under pressure. The container comprises a tension surface, and a bag containing the liquid to be dispensed, which is in contact with the tension surface. An actuatable valve to which the bag is open serves to controllably release the liquid from the bag, and a diaphragm forms a floor to the tension surface underneath the bag. The diaphragm is elasticated and presses the bag against the tension surface to flatten the bag, thus to expel the contents under pressure.

Abstract

A device for dispensing a material under pressure comprises one or more elastic portions defining a chamber within which the material is to be contained, and one or more non-elastic portions that are coupled to the elastic portion(s). The device optionally and preferably also includes an outlet for dispensing the material out of the chamber. When the material is contained within the chamber, the elastic portion(s) is stretched to apply inwardly directed compressive forces and urge a reduction in a volume of the chamber.

Abstract

Devices and methods for dispensing a fluidly dispensable material under pressure but without using a gas propellant are presented. In some embodiments an elastic sleeve is utilized to impart pressure to a bag of dispensable material positioned within the sleeve. Pressure so created pressurizes contents of the bag, which can then be dispensed through a valve. Methods for manufacturing various embodiments are presented.
