Description

  The present invention relates to aerosol products and containers thereof. More specifically, the present invention relates to an aerosol product capable of adjusting the injection volume immediately before use and a container thereof.

JP 7-315462 A JP 11-179250 A

In the aerosol product, the contents are continuously ejected while the user operates the ejection member, and therefore the amount of the aerosol product is adjusted according to the sense of the user. Therefore, the injection amount becomes too small to achieve the effect set by the manufacturer, the injection amount becomes too high and the feeling of use deteriorates, and depending on the contents (active ingredients, etc.), it may be harmful to the human body. The result will also be.
On the other hand, there is known a fixed injection type aerosol valve that can inject a predetermined amount by a single injection operation. This fixed quantity injection type aerosol valve is provided with a fixed quantity chamber in the passage of contents. This aerosol container equipped with a constant-injection type aerosol valve opens the fixed-quantity chamber to the atmosphere by performing an injection operation, and at the same time shuts off the communication between the fixed-quantity chamber and the container body and continues to operate the injection member. The contents other than the contents in the quantitative chamber accommodated before operation are configured not to be ejected. Therefore, excessive injection of contents can be prevented. However, since the injection capacity cannot be arbitrarily changed, it is necessary to repeatedly perform the injection operation when it is desired to inject more than the normal amount.

  Patent Document 1 discloses a metering valve that uses an aerosol container upside down. This metering valve has a hole for introducing the contents into the housing and a space for temporarily storing the contents. Therefore, the contents are introduced from the hole into the space in the housing by inverting the aerosol container provided with the metering valve. Then, by performing an injection operation in the inverted state, the space in the housing and the atmosphere are communicated with each other, and at the same time, the hole is closed, and the contents contained in the space are injected.

  Patent Document 2 discloses a filling system capable of filling a required amount of contents (stock solution) into an aerosol container at the time of use. Further, it is described that the refill container (aerosol container) of the filling system and the cylinder in the container are made of translucent synthetic resin or glass, and the cylinder is provided with a scale. Therefore, it is possible to arbitrarily control the injection capacity by injecting while visually observing the cylinder in the filled refill container.

  However, the metering valve of Patent Document 1 does not allow the injection capacity to be arbitrarily changed because the hole, which is the introduction hole, is closed in the valve by the injection operation, as in the conventional valve. In addition, since the pressure in the container is not transmitted to the space, the contents in the space will be injected with its own pressure, and the momentum will be weakened during the injection, or the entire contents in the space will not be injected There is. In addition, the refill container disclosed in Patent Document 2 can arbitrarily control the injection volume by injecting while visually observing the cylinder, but it is difficult to visually inspect the cylinder scale while performing the injection operation. In addition, since the injection does not stop as long as the injection operation is performed, it can be said that it is difficult to accurately control the injection capacity.

  An object of the present invention is to provide an aerosol container in which a user can adjust the injection volume immediately before use and prevent injection exceeding the injection volume.

  The aerosol product of the present invention comprises a container body, an aerosol valve fixed to the mouth of the container body, a liquid storage member connected to the aerosol valve, and an aerosol composition filled in the container body. The liquid storage member includes an introduction hole that opens to a gas phase portion of the aerosol composition, and includes a cylindrical liquid supply passage that directly communicates the vicinity of the bottom of the liquid storage member and the inside of the aerosol valve.

The lower chamber has an introduction hole that communicates with the container body, and is provided with a liquid supply passage that communicates the vicinity of the bottom of the lower chamber and the upper chamber (claim 12).

  The aerosol product of the present invention comprises a container body, an aerosol valve fixed to the mouth of the container body, a liquid storage member connected to the aerosol valve, and an aerosol composition filled in the container body. The liquid storage member includes an introduction hole that opens in a gas phase portion of an aerosol composition (hereinafter referred to as the contents), and a cylindrical liquid that directly communicates the vicinity of the bottom of the liquid storage member and the inside of the aerosol valve. Since the supply passage is provided, injection is possible only after the liquid phase portion of the contents is introduced into the liquid storage member through the introduction hole by shaking the aerosol container upside down or upside down before injection. Therefore, the injection capacity can be adjusted depending on the number of times the aerosol container is shaken upside down. When the aerosol valve is opened, only the contents introduced into the liquid storage member are smoothly injected, and after the contents in the liquid storage member are injected, only the gas of the aerosol composition is injected. Therefore, the user can recognize that the intended contents have been ejected, and can prevent excessive ejection.

  Moreover, since the cylindrical liquid supply passage which directly communicates the vicinity of the bottom of the liquid storage member and the inside of the aerosol valve is provided, the liquid of the aerosol composition introduced into the liquid storage member can be changed without changing the injection state. The whole quantity can be injected.

  Further, the aerosol product of the present invention has a particularly flammable content even if the valve is opened when it is not necessary, since only gas is injected even if the injection operation is performed unless the liquid content is stored in the liquid storage member. Even things are safe. In addition, when the aerosol product is no longer needed, if the valve is fixed in the open position, only the gas is discharged, and even if the stock solution is a flammable material, it is not discharged and is safe to ignite. Furthermore, the stock solution after gas discharge can be recovered (claim 1).

In such an aerosol product, when the liquid storage member has a bottomed cylindrical shape and is attached to the housing of the aerosol valve, a conventionally known aerosol container is used, and the liquid storage member is simply attached to the current aerosol valve. The structure is simple. In particular, it can be manufactured using an existing manufacturing apparatus, which is preferable. In addition, it is easy to mount a valve even in a bottle-shaped container body having a small mouth portion. Furthermore, the maximum ejection volume that can be ejected at one time can be adjusted by the inner diameter and length of the liquid storage member (claim 2).
Further, when the cylindrical liquid supply passage is a tube having both ends open, the opening at one end is disposed near the bottom of the liquid storage member and the opening at the other end is attached to the aerosol valve, the length of the liquid supply passage is long. The sheath inner diameter can be freely changed, and the injection state can be adjusted (Claim 3).
Furthermore, when the liquid supply passage is a cylindrical portion integrally formed at the lower portion of the housing, and the lower end opening of the cylindrical portion is disposed near the bottom of the liquid storage member, the number of parts can be reduced, and the cost can be reduced. Can be produced (claim 4).

  As described above, when the liquid storage member is attached to the liquid supply passage connected to the aerosol valve, it is easy to attach the liquid supply passage and the liquid storage member to the aerosol valve as a whole. In particular, when a dip tube is used as the liquid supply passage, these can be handled as one unit.

Further, when the translucent container body and the liquid storage member are used and the scale indicating the injection capacity is provided on the liquid storage member, more accurate injection is possible. For example, when used for aerosol products such as deodorants and fragrances that are injected into a space, the injection capacity can be accurately adjusted according to the size (volume) of the room to be injected. In addition, it can be suitably used when the appropriate usage amount per day or per time varies depending on the age of the user or the like, such as a pharmaceutical product or a non-pharmaceutical product (claim 7). Furthermore, when the whole liquid storage member is exposed to the gas phase part of the aerosol composition, it becomes easier to visually confirm the amount of contents introduced into the liquid ejection member (claim 8).

Moreover, when the cross-sectional area of the introduction hole of the liquid storage member is 5 mm ² or more, the liquid of the aerosol composition can be smoothly introduced into the liquid storage member (claim 9).

  A second aspect of the aerosol product of the present invention comprises a container body, an aerosol valve fixed to the mouth of the container body, and an aerosol composition filled in the container body. The aerosol valve is an aerosol. An introduction hole that opens to the gas phase part of the composition, a liquid storage part for storing the liquid of the aerosol composition introduced from the introduction hole, and a liquid supply passage for supplying the liquid in the liquid storage part into the housing Therefore, as described above, the user can inject the contents into the liquid storage member before use, and can inject any amount (claim 10).

  An aerosol product 10 shown in FIG. 1 has a bottomed cylindrical container body 11 having translucency, an aerosol valve 12 fixed to the mouth thereof, and an injection member (push button) attached to the stem of the aerosol valve. 15, a liquid storage member 13 connected to the lower end of the aerosol valve, and an aerosol composition 14 (A: gas phase portion, B: liquid phase portion). Here, let the thing which is not filled with the contents 14 be an aerosol container.

  The container body 11 includes a bottom part 11a, a body part 11b, a shoulder part 11c, a neck part 11d, and a mouth part 11e, and is molded into a bottle shape using a light-transmitting material such as a synthetic resin such as polyethylene terephthalate or pressure-resistant glass. Has been. However, an opaque material such as a metal or an opaque synthetic resin may be used.

  As shown in FIG. 2 a, the aerosol valve 12 includes a housing 18 having a flange portion 17 mounted on the top surface of the mouth portion 11 e of the container body via a gasket 16, and a vertical movement into the housing 18. A stem 19 that is freely accommodated, a spring 20 that constantly biases the stem 19 upward, a stem rubber 22 that closes the stem hole 21 of the stem 19, and a tube mounting portion 23 provided at the lower end of the housing 18 It consists of a dip tube (cylinder) 24 mounted around the periphery and a cover cap 26 for fixing the aerosol valve 12 to the mouth portion 11e of the container body 11. A communication hole 25 that communicates with the inside of the container body 11 is provided in the tube mounting portion 23 at the lower end of the housing 18.

The liquid storage member 13 has a bottomed cylindrical shape including a bottom portion 13 a, a cylindrical portion 13 b, and an upper end opening 13 c, and the upper end opening 13 c is mounted on the outer periphery of the tube mounting portion 23. Further, as shown in FIG. 2c, a slit 27 extending downward is formed in the upper end opening 13c. And the internal space 28 which consists of the bottom part 13a and the cylinder part 13b of a liquid storage member acts as a liquid storage chamber for storing the contents (liquid). The volume of the liquid storage member 13 is preferably 0.1 to 5 ml, particularly preferably 0.3 to 3 ml.
Examples of the material for the liquid storage member 22 include translucent synthetic resins such as polyethylene terephthalate, polyethylene, polypropylene, polyamide, and polyacetal. However, an opaque material such as a metal or an opaque synthetic resin may be used.

By mounting the liquid storage member 13 thus configured on the outer periphery of the tube mounting portion, the slit 27 communicates the interior of the container body 11 and the internal space 28 as shown in FIG. 2b. That is, the slit 27 functions as an introduction hole for introducing the contents in the container body 11 into the liquid storage member 13. The cross-sectional area of the introduction hole is preferably 5 mm ² or more, and particularly preferably 10 mm ² or more. At this time, the dip tube 24 connected to the lower end of the housing extends to the vicinity of the bottom portion 13a of the liquid storage member 13, and acts as a liquid supply passage that connects the vicinity of the bottom portion of the liquid storage member and the inside of the aerosol valve. Then, the contents stored in the liquid storage member 13 are introduced into the housing 18 by the dip tube 24 in the same manner as a normal aerosol product.

The aerosol composition 14 is divided into a liquid phase part B and a gas phase part A in the container body 11, and the slit 27 communicates with the gas phase part of the contents when the aerosol container 10 is allowed to stand. So as to be filled.
The content to be filled in this way (aerosol composition) is not particularly limited, but there is a propellant composed of a stock solution in which an active ingredient is blended with a solvent, and liquefied petroleum gas, dimethyl ether, and a liquefied gas that is a mixture thereof. preferable.
Active ingredients include, for example, deodorant ingredients, aromatic ingredients, insecticide ingredients, sterilizing ingredients, etc., spatially effective ingredients, antifungal ingredients, antipruritic ingredients, analgesic ingredients, antihistamine ingredients, bactericidal ingredients, local anesthetic ingredients, refreshing ingredients , Active ingredients for human bodies such as moisturizing ingredients and hair-growth ingredients.
Examples of the solvent include water such as purified water and ion exchange water, lower alcohols such as ethanol and isopropanol, hydrocarbons such as kerosene and liquid paraffin, ester oils such as isopropyl myristate, silicone oils such as methylpolysiloxane, and the like. .

  In the aerosol product 10 configured in this manner, the container body 11 is filled with the stock solution, the aerosol valve 12 equipped with the liquid storage member 13 is fixed to the container body 11, the stem of the aerosol valve is pushed down, and the propellant is discharged from the stem. Manufactured by filling. The propellant may be filled with an under cup immediately before the aerosol valve is fixed. Alternatively, the aerosol valve 12 having the liquid storage member 13 attached to the container body 11 may be fixed to manufacture an aerosol container, and then the aerosol valve stem may be pushed down to fill the stock solution and propellant from the stem. . These can be appropriately selected depending on the type of contents.

  Next, the usage method of this aerosol product 10 is demonstrated. Immediately before the aerosol product 10 is sprayed, the aerosol product 10 performs a shaking action such as holding the container body 11 and shaking it up and down or reversing it up and down. As a result, the contents in the container body 11 are uniformly mixed, and the contents are introduced from the slit 27 (introduction hole) of the liquid storage member 13 into the internal space 28 (liquid storage chamber). This is because the aerosol product 10 is not jetted unless the liquid storage member 13 is filled with the liquid content. Next, when the injection member 15 is pushed down to open the valve, the liquid content in the internal space 28 is introduced from the lower end opening of the dip tube 24 into the housing 18 through the dip tube 24, and further into the stem 19, the injection It is injected to the outside from the injection hole through the passage of the member. At this time, since the lower end opening of the dip tube 24 is positioned near the bottom of the liquid storage member 13, all of the liquid contents stored in the liquid storage member 13 can be ejected without changing the ejection state. After the injection, the internal space 28 (liquid storage chamber) of the liquid storage member 13 is empty, and the liquid storage member 13 communicates with the gas phase portion of the contents of the container main body 11, so that only gas is injected. Thus, the user does not excessively eject the liquid contents.

  The amount of contents to be ejected can be adjusted by the number and time of the aforementioned shaking actions, and the maximum ejected amount that can be ejected at one time can be adjusted by the volume of the internal space of the liquid storage member. Moreover, since the container main body and the liquid storage member are comprised with the translucent material in this form, the amount of contents stored in the liquid storage chamber from the outside can be confirmed.

  The aerosol product 30 shown in FIG. 3a has a cylindrical portion of the liquid storage member 31 that is shorter than the liquid storage member 13 of the aerosol product of FIG. The injection amount is reduced. Moreover, the scale 32 (refer FIG. 3b) which shows injection capacity is provided in the outer peripheral surface of the cylinder part of the liquid storage member 31, and it arrange | positions so that the liquid storage member 31 whole may be exposed in a gaseous-phase part. . A slit 33 (introduction hole) is formed in the upper part of the liquid storage member 31. One or more slits 33 may be provided. The size of the introduction hole can be appropriately adjusted in the manufacturing stage in consideration of the use of the contents.

  The aerosol product 40 shown in FIG. 4 extends the lower end of the tubular tube mounting portion 41 at the lower end of the housing so that the opening 44 is positioned near the bottom portion 43 of the liquid storage member 42. Other configurations are substantially the same as the aerosol product 10 of FIG. In this case, the tube mounting portion 41 is replaced with a dip tube as a liquid supply passage that communicates the vicinity of the bottom of the liquid storage member and the inside of the housing of the aerosol valve, and includes an opening 44. Thereby, the number of parts of an aerosol product can be reduced and a manufacturing process can be reduced.
