Double pressurized container, discharge product, discharge member, dispenser system and manufacturing method for discharge product

A method for manufacturing a discharge product comprising the steps of:

• preparing a double pressurized container comprising an outer container;
• an inner container stored inside the outer container and having flexibility;
• and a plug for sealing both of the outer container and the inner container;
• charging the concentrate inside the inner container;
• charging a pressurizing agent between the inner container and the outer container;
• replacing a gas inside the inner container with a gas which has a solubility to the concentrate higher than that of air;
• fixing the plug to an opening of the outer container and the inner container;
• and
• contracting the inner container by dissolving gas inside the inner container into the concentrate.

A method for manufacturing a discharge product comprising the steps of:

• preparing a double pressurized container comprising an outer container;
• a gas permeable inner container stored inside the outer container and having flexibility;
• and a plug for sealing both of the outer container and the inner container;
• charging a concentrate inside the inner container;
• charging a pressurizing agent which has a solubility to the concentrate higher than air into a space between the inner container and the outer container;
• fixing the plug to an opening of the outer container and the inner container;
• and
• contracting the inner container by dissolving the pressurizing agent charged between the inner container and the outer container into the concentrate by permeating the inner container.
