Definitions

  • the present invention relates to an aerosol product having a valve with a stem protruding from an aerosol container, and a nozzle that fits with the stem, and more particularly to an aerosol product that favorably sprays a mist of the content therein.
  • Aerosol products having a valve with a stem protruding from an aerosol container, and a nozzle that fits with the stem, are well known, and so are products that spray a mist of the contents in the container from the nozzle.
  • the content is atomized as it is ejected from the outlet orifice.
  • the amount of ejected content, the ejection pressure, and the nozzle outlet shape are designed suitably in accordance with the properties of the content so as to produce a favorable spray of mist by the expansion force of the liquefied gas near the outlet orifice.
  • the ejection pressure of the content and the expansion force of the liquefied gas near the outlet orifice are adjusted depending on the type and amount of the liquefied gas to be mixed with the content, while the amount of ejected content is regulated by the flow paths of the valve and nozzle.
  • An aerosol product known from Patent Literature 1 has a valve with a housing configured to have a Venturi aperture in the circumferential wall and to absorb the liquid inside the container by the capillary action, to cause the liquid to evaporate through the Venturi effect and generate an aerosol in a lower end part of the housing.
  • An aerosol product known from Patent Literature 2 includes a first container holding a gas and a second container holding a liquid.
  • the gas held in the first container is expelled as a gas stream from a first nozzle part.
  • the aerosol product includes a second nozzle part for discharging the liquid held in the second container such that the liquid is drawn by the gas stream emerging from the first nozzle part and forced into the area of the expelled gas stream.
  • An aerosol product known from Patent Literature 3 includes an inner aerosol device that sprays an atomized liquid, and an outer aerosol device that ejects a gas for delivering the atomized liquid sprayed from this inner aerosol device.
  • Patent Literature 2 uses the Venturi effect, and the liquid is exposed to the outside air, because of which applicable liquids are much limited, and entailed the problem that the aerosol container as a whole was bulky.
  • the present invention solves the problems described above, and it is an object of the invention to provide a simple-structured aerosol product with few limitations on applicable liquids and capable of spraying a mist of fine particles without giving too much sensation of coldness.
  • the aerosol product according to the present invention is an aerosol product having a valve with a stem protruding from an aerosol container, and a nozzle that fits with the stem, the aerosol container including a plurality of holding spaces by being partitioned and a plurality of valves corresponding to the holding spaces, at least one of the plurality of holding spaces being a liquefied gas containing section that holds a liquefied gas, and at least one of the plurality of valves being a gas phase valve that ejects vaporized gas from the liquefied gas containing section, whereby the problems noted above are solved.
  • the aerosol product according to claim 1 has the aerosol container including a plurality of holding spaces by being partitioned and a plurality of valves corresponding to the holding spaces, at least one of the plurality of holding spaces being a liquefied gas containing section that holds a liquefied gas, and at least one of the plurality of valves being a gas phase valve that ejects vaporized gas from the liquefied gas containing section.
  • the content such as a liquid and the vaporized gas mix with each other inside the nozzle, the content can be atomized into a mist of fine particles that hardly gives the sensation of coldness.
  • the two valves can be designed optimally as required, which reduces limitations on applicable liquids.
  • aerosol containers having a known dual valve configuration can be utilized, which results in a simple structure.
  • the aerosol container includes a can-like vessel and one or more content holding bags accommodated inside the can-like vessel, the liquefied gas containing section being formed by a space outside the content holding bag inside the can-like vessel, and a valve or valves other than the gas phase valve being configured to eject a content inside the content holding bag.
  • the liquefied gas containing section being formed by a space outside the content holding bag inside the can-like vessel, and a valve or valves other than the gas phase valve being configured to eject a content inside the content holding bag.
  • the aerosol container is formed by one can-like vessel, the container can be designed to have a shape easy to hold for the user.
  • the nozzle includes a fitting part that fits with stems of the plurality of valves, a mixing part where fluids ejected from the plurality of valves are mixed, and an outlet orifice for forcing out the mixed fluids. Spraying of an optimal mist is made possible by a suitable internal design of a single nozzle, which enables an even simpler structure.
  • Fig. 1 is a cross-sectional illustrative view of an aerosol product according to one embodiment of the present invention.
  • An aerosol product 100 according to a first embodiment of the present invention is a product known as a dual valve type, which has two valves 110 fixed to the mouth of an aerosol container 101 by means of a mounting cup 102, with two stems 111 protruding upwards, as shown in Fig. 1 .
  • a content holding bag 132 is provided in the holding space inside the aerosol container 101 so that the container is partitioned into two holding spaces, i.e., inside and outside of the content holding bag 132.
  • the content holding bag 132 tightly contains a content F therein, while the outside of the content holding bag 132 forms a liquefied gas containing section 131 where a liquefied gas LG is stored.
  • the liquefied gas LG may be any of LPG, dimethyl ether, alternatives for CFCs and so on that are used as the propellant for common aerosol products.
  • Non-flammable, more environmentally friendly hydrofluoroolefin is preferable, and HFO-1234ze is even more preferable.
  • valve 110 is connected to spray the content F inside the content holding bag 132, while the other valve 110A (hereinafter, “gas phase valve 110A”) is connected to force out the vaporized gas that is the gaseous phase of the liquefied gas LG stored in the liquefied gas containing section 131.
  • gas phase valve 110A is connected to force out the vaporized gas that is the gaseous phase of the liquefied gas LG stored in the liquefied gas containing section 131.
  • a nozzle 120 is attached to the stems 111 protruding upward from the two valves 110 via a fitting part 122. Pressing down the nozzle 120 opens the valve 110 and gas phase valve 110A, whereby the vaporized gas is forced out from the stem 111 by the pressure of the gaseous phase of the liquefied gas LG stored in the liquefied gas containing section 131, and the content F is forcefully projected from the stem 111, as the content holding bag 132 is pressurized, too.
  • the content F and vaporized gas are mixed inside the nozzle 120 and driven out from an outlet orifice 121, and in this process, the content F is atomized into a fine mist as it is sprayed.
  • This embodiment includes a residual quantity reduction member 134 attached below the valve 110 inside the content holding bag 132 and configured to keep the amount of ejected content F consistent until the end and to reduce the amount of leftover.
  • the content F Since the content F is forced out by the pressure the content holding bag 132 receives from the liquefied gas containing section 131, the content F does not contact the liquefied gas LG during storage, and there is no need to mix in a material that applies pressure to the content F.
  • Table 1 shows the test results when water, alcohol, and vegetable oil were sprayed as a mist of the content F, using the aerosol product 100 described above.
  • test conditions were as follows:
  • Flow path diameter of the valve 110 for the content F 0.35 mm
  • Flow path diameter of the gas phase valve 110A 0.35 mm
  • Liquefied gas HFO-1234ze
  • Flow path diameter of the valve 110 for the content F 2.00 mm
