Embodiment 1

[0398] Both the outer container and the inner container used a pressurized container 11 made of polyethylene terephthalate (the filling volume of the outer container was 210 ml), and 120 g of water was filled in the inner container as the stock solution C. Next, the air in the head space Hs in the inner container was replaced with carbon dioxide (solubility in water: 0.76 (25° C., 1 atm)), and a lid made of polyethylene terephthalate was covered. Then, nitrogen gas (solubility in water: 0.014 (25°C, 1 atm)) as the pressurizing agent P is filled into the pressurizing agent storage chamber Sp from between the outer container and the lid, and the lid is fixed to the container body by ultrasonic welding. . The pressure immediately after manufacture was 0.5 MPa. Then, it was stored in a constant temperature room at 25° C., and after one day, the inner container shrank, and the gas phase portion almost disappeared.

Embodiment 2

[0400] Both the outer container and the inner container used a pressurized container 11 made of polyethylene terephthalate (the filling volume of the outer container was 210 ml), and 120 g of water was filled in the inner container as the stock solution C. Next, a lid made of polyethylene terephthalate was covered on the container main body. Then, carbon dioxide (solubility in water: 0.76 (25°C, 1 atm)) as the pressurizing agent P is filled into the pressurizing agent storage chamber Sp from between the outer container and the cover, and the cover is fixed to the container main body by ultrasonic welding. . The gas G of the headspace Hs in the inner container is air. The pressure immediately after manufacture was 0.5 MPa. Then, it was stored in a constant temperature room at 25° C., and after one day, the inner container shrank, and the gas phase portion almost disappeared. Therefore, in Example 2, the replacement steps S2 and S4a are unnecessary.

Embodiment 3

[0402] Both the outer container and the inner container used a pressurized container 11 made of polyethylene terephthalate (the filling volume of the outer container was 210 ml), and the inner container was filled with 100 g of ethanol as the stock solution C. Next, a lid made of polyethylene terephthalate was covered on the container main body. Then, nitrogen gas (solubility in ethanol: 0.14 (25° C., 1 atm)) as the pressurizing agent P was filled into the pressurizing agent storage chamber Sp from between the outer container and the lid, and the lid was fixed to the container by ultrasonic welding. main body. The gas G of the headspace Hs in the inner container is air. The pressure immediately after manufacture was 0.5 MPa. Then, it was stored in a constant temperature room at 25° C., and after one day, the inner container shrank, and the gas phase portion almost disappeared. Therefore, in Example 3, the replacement steps S2 and S4a are unnecessary.

Abstract

A double pressurized container 11, 31 comprising an outer container 13, 33, a flexible inner container 14, 34 housed inside the outer container 13, 33, and a lid body 15, 35 welded to the outer container 13, 33 and the inner container 14, 34 and sealing both the outer container 13, 33 and the inner container 14, 34, wherein the space inside the inner container 14, 34 constitutes a liquid feedstockstorage chamber for storing a liquid feedstock C, the space between the outer container 13, 33 and the inner container 14, 34 constitutes a pressurizing agent storage chamber to be filled with a pressurizing agent P, and the lid body 15, 35 is provided with an unsealing part 15d, 44 for unsealing the liquid feedstock storage chamber. A discharge product 11a, 31a comprises the double pressurized container 11 filled with the liquid feedstock C and the pressurizing agent P.

Description

technical field [0001] The present invention relates to a dual pressurized container, a spout article, a spout component, a dispenser system using them, and a method of making the spout article. In addition, in the following description, a "pressurized product" or a "double pressurized product" may be called instead of a "sprayed product", but they are the same. Background technique [0002] In Patent Document 1 Figure 11 In, a content storage container is disclosed, which includes a container body having an opening at the upper end, and a valve housing portion that closes the opening and is fixed to the container body. The valve housing portion has a cylindrical housing portion and can The detachment fits into the unsealed portion of the hole formed on the bottom surface of the case portion. In addition, in Patent Document 1 Figure 7 discloses a content storage container, which is provided with a sealing portion that is unsealed by breaking at the bottom of the valve ho...
