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 gas-filled resilient body arranged in a buffer housing between the pressurizing means and the outlet so as to buffer the pressurized liquid in the 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
