Abstract
A gas-filled resilient body and uses thereof are described. The gas-filled resilient body may be used as a valve member, as a spring or as a gas-propelled dispenser.
Claims20
A method of using a partially gas-filled resilient body, comprising:
- using the partially gas-filled resilient body as a gas-propelled dispenser,
- wherein the resilient body is filled with gas and a material to be dispensed;
- and
- wherein the material is dispensed by piercing the resilient body.

A rapid-action dispensing device, comprising:
- means for pressurizing a liquid to be dispensed,
- an outlet opening closed off by a manually operable valve, and
- a resilient body filled with gas only arranged in a buffer housing between the pressurizing means and the outlet so as to buffer the pressurized liquid in a volume defined between the gas-filled resilient body and a wall of the buffer housing by compressing the gas-filled resilient body until the valve is manually opened.
A dispensing device, comprising:
- a housing having an outlet opening,
- a resilient body partially filled with gas and partially filled with a material to be dispensed, and
- a piercing member for piercing the resilient body so as to allow the material to be urged out by the gas,
- wherein the piercing member and the resilient body are movable with respect to each other.
