[Prior Art]

 It provides proper moistness to dry skin, prevents makeup loss, hydrates hair to ensure a clean wave, and cleans food on clothing to help keep your skin clean. In order to meet the demands for a refreshing feeling, only pure water that does not contain minerals such as calcium and magnesium is pressed into the spray container together with an inert gas such as nitrogen gas, and if necessary, pure water is added. A pure water spray in which water is sprayed from a nozzle is known. This pure water spray is made by filling pure water with inert gas into the container body.To prevent bacterial growth, heat sterilization from the outside of the container body or irradiation with gamma rays is performed after filling. Processing such as doing is done.

[0003]

[Problems to be solved by the device]

 As described above, in order to maintain the quality of the pure water filled in the container body, conventionally, after filling the container body, gamma rays are irradiated from the outside of the container body or the container itself is sterilized by immersing it in hot water. It is processing. However, such a sterilization means requires appropriate equipment and also has a problem that the labor required for sterilization is considerably involved and the cost is increased.

Therefore, the present invention solves the above-mentioned problems of the conventional pure water spray, and in order to send the pure water to the nozzle portion attached to the upper portion of the container body, the tip of the water pipe attached to the inside of the container body, It is an object of the present invention to provide a sterile pure water spray in which a filtration case filled with a hollow fiber membrane for sterilization is attached to send completely sterile pure water to a nozzle through a water pipe.

[0005]

[Means for Solving the Problems]

 To describe the structure of the present invention for achieving the above-mentioned purpose in detail, pure water and an inert gas are press-fitted inside the container body, and pure water is sprayed from a nozzle attached to the head of the container body as needed. In the pure water spray configured as described above, a water pipe made of a flexible pipe that sends pure water to the nozzle portion is attached to the inside of the container body, and the hollow fiber membrane is filled inside at the tip of the water pipe. A sterile pure water spray characterized in that a filter case is attached, and a weight having a water passage hole is attached to the lower end of the filter case.

The hollow fiber membrane to be filled in the above-mentioned filtration case may be one having fine pores that allow water to pass but block passage of bacteria, and usually has a pore diameter of 0.45 μm or less, It is suitable to use those having fine pores of 0.20 μm or less. By using a hollow fiber membrane with such fine pores, it is possible to spray completely sterile pure water from the nozzle part on the top of the container body without using conventional gamma irradiation or heat sterilization. It will be.

【Example】

 Hereinafter, a specific configuration of the sterile pure water spray of the present invention will be described in detail based on the illustrated embodiment. FIG. 1 is a half sectional view showing one embodiment of the sterile pure water spray of the present invention, and FIG. 2 is an enlarged sectional view showing details of a filtration case filled with a hollow fiber membrane.

Reference numeral 1 in the figure shows the entire spray container, and this spray container 1 is a container body 2 into which pure water is pressed together with an inert gas such as nitrogen gas or helium gas, and is attached to or detached from the head of the container body 2. A cap 3 is attached to the container body 2 freely, and a nozzle portion 4 is attached to the head of the container body 2 for spraying pure water enclosed therein together with an inert gas. The nozzle portion 4 may have a conventionally known structure, and since the present invention does not relate to the structure of the nozzle portion, a structural explanation of this portion will be omitted. Reference numeral 5 denotes a water passage pipe provided inside the container body 2 for supplying pure water to the nozzle portion 4. The water passage pipe 5 is composed of a flexible pipe. Reference numeral 6 denotes a filtration case attached to the tip of the water pipe 5. Inside the filtration case 6, as shown in FIG. 2, for example, a large number of hollow fiber membranes 7 having both open ends are bundled in a U-shape. At the same time, the hollow fiber module 13, which is bonded and fixed to the joint 12 without blocking the openings at both ends, partitions the inside of the filtration case 6 into the upper chamber 14 and the lower chamber 15 by the joint 12. Moreover, the openings of the hollow fiber membranes 7 are attached so as to communicate with the upper chamber 14. Reference numeral 8 denotes a weight attached to the lower end opening 9 of the filtration case 6 so as to close the opening 9. The weight 8 guides pure water into the lower chamber 15 in the filtration case 6. A large number of water passage holes 10 are provided. When attaching the weight 8 to the lower end opening 9 of the filtration case 6, as shown in FIG. 2, a fitting wall 11 having a required height is provided so as to protrude from the peripheral portion of the weight 8 and the fitting is performed. The wall 11 may be tightly fitted to the lower end portion of the filtration case 6, or the weight 8 may be adhered to the lower end surface of the filtration case 6 using an adhesive, although not shown. .

As described above, the water pipe 5 is made of a flexible material, and the weight 8 is provided at the tip of the water pipe 5. Even if the upper and lower sides of the spray container 1 are turned upside down or laid sideways by the action, the filter case 6 provided with the weight 8 can always be positioned below the liquid level in the container body 2. The pure water in the container body 2 can be surely ejected from the nozzle portion 4 even when the spray container 1 is turned upside down or lying down.

Pure water in the container main body 2 enters the lower chamber 15 in the filter case 6 through the water passage holes 10 provided in the weight 8 and is filled in the filter case 6. Each hollow fiber membrane 7 of the hollow fiber module 13 is filtered, and filtered water is obtained inside each hollow fiber membrane 7. By such filtration, even if bacteria exist in pure water, they can be removed. The completely sterile pure water that has passed through the hollow fiber membranes 7 passes through each hollow fiber membrane 7 and is collected from the openings at both ends into the upper chamber 14 which is an upper water collecting space in the filtration case 6, and is passed through. It passes through the water pipe 5 and goes outward from the nozzle portion 4 attached to the head of the container body 2 and is atomized into a fine mist with the inert gas. The container body 2 is made of aluminum in order to prevent rusting, and the inner peripheral surface of the aluminum container body 2 is coated with, for example, epoxyphenol resin. Layers have been formed.

[Effect of the device]

 As described above, the sterile pure water spray of the present invention has a structure in which the hollow fiber membrane is filled in the filter case attached to the tip of the water passage pipe, so that even if pure water in the container body contains bacteria. Even if it is, it is possible to spray completely sterile pure water from the nozzle of the container body, and the conventional sterilization treatment by heat sterilization or gamma ray irradiation is not necessary. It also eliminates the need for a heat sterilizer and gamma irradiation equipment.
