Abstract
An aerosol product comprising a double-chamber container separated by a movable partition capable of dividing contents therewith, one spatial portion thereof being loaded with contents to be discharged and the other spatial portion being loaded with compressed gas for pressurizing. The compressed gas is a mixed compressed gas of at least two types of mixed gas, at least a part of the partition presents permeability of the compressed gas, and the mixed compressed gas selectively permeates the partition to be dissolved in the contents to be ready for discharge.
Claims8
An aerosol product comprising a double-chamber container separated by a movable partition capable of dividing contents therewith, one spatial portion thereof being loaded with contents to be discharged and the other spatial portion being loaded with compressed gas for pressurizing, wherein the compressed gas is a mixed compressed gas of at least two types of mixed gas, at least a part of the partition presents permeability of the compressed gas, the mixed compressed gas selectively permeates the partition to be dissolved in the contents to be ready for discharge, and the compressed gas for pressurizing is a mixed gas including a compressed gas of which Ostwald coefficient is not less than 0.5 with respect to the contents at a temperature of 25° C. and a second compressed gas of which Ostwald coefficient is not more than 0.3.
A method for manufacturing an aerosol product employing a double-chamber container separated by a movable partition of which at least a part presents gas permeability, and which is capable of separating contents therewith, the method including the steps of
- (a) loading contents to be discharged into one spatial portion of a double-chamber container interior,
- (b) loading a mixed compressed gas for pressurizing at least two types of mixed gases into the other spatial portion of the double-chamber container interior, and
- (c) dissolving the mixed compressed gas into the contents after selectively making the gas permeate the partition,
- and in that the compressed gas for pressuring is a mixed gas including a compressed gas of which Ostwald coefficient is not less than 0.5 with respect to the contents at a temperature of 25° C. and a second compressed gas of which Ostwald coefficient is not more than 0.3.
