The present invention relates to an actuator for an aerosol container having a coating surface, and particularly to an actuator for an aerosol container and an aerosol product that can quickly transmit the contents onto the coating surface with a simple operation and can apply the contents to an object to be coated. It is.

In general, various actuators have been proposed for aerosol containers that obtain efficacy by directly applying the contents to the target, such as antiperspirant deodorizers, pain relievers, anti-inflammatory agents, pest repellents, cleaners, and paints. .
For example, Patent Document 1 describes an application section that connects to a stem (30) provided at the container mouth of an aerosol container body (aerosol container) and can apply the contents (aerosol composition 6) to an application target (affected area). An aerosol product (aerosol product for human body 100) using an actuator for an aerosol container (application member 1) having (10) is described.

The aerosol container actuator (application member 1) of this aerosol product (aerosol product for human body 100) includes a push button (main body 2) and a cylindrical application part (10) attached to the top surface of the push button (main body 2). , a cylindrical tube portion extending downward from the axis from the center of the push button (main body 2), a stem connection base (stem attachment portion 2c) provided at the lower end of the tube portion, and a stem connection base (stem attachment portion 2c) that connects the tube portion to the stem connection base (stem attachment portion 2c). It has a main body passage (2b) that communicates from part 2c) to the upper surface of the push button (main body 2), and the contents (aerosol Composition 6) can be stored temporarily.

Moreover, the application part (10) is a laminate composed of a soft foam (11) and a hard foam (12), and the stored content (aerosol composition 6) is transferred to the application part (10). The soft foam ( 11), the application part (10) deforms according to the shape of the application target (affected area) and comes into close contact with the application target (affected area), allowing efficient application of the medicinal solution.

Furthermore, the soft foam (11) and the hard foam (12) have central passages (11a, 12a) extending coaxially with the main body passage (2b) and serving as an outflow passage for the contents (aerosol composition 6). is provided so that a part of the content (aerosol composition 6) released into the storage space (2a) can be directly impregnated into the soft foam (11), and the content (aerosol composition 6) can be liquefied. The content (aerosol composition 6) can be impregnated into the application area (10) outward from the central passages (11a, 12a) in a short time by the propulsion force generated by gas vaporization, and can be applied to the application target (affected area) through a spraying operation. This can shorten the time it takes.

Japanese Patent Application Publication No. 2007-330313

However, the aerosol container actuator known in Patent Document 1 still has room for improvement.
In other words, the content is stored in the storage space and then impregnated into the application section, and then the application section is pressed against the object to be applied to apply the liquid content in the application section, so it is possible to apply the liquid to the object from the spray operation. There was a risk that there would be a time lag between the two.
In addition, there is a risk that the contents may remain as residual liquid in the storage space and deteriorate within the storage space, or that the residual liquid dries and the components in the residual liquid stick to the main body passage and block the main body passage. there were.
Furthermore, in order to cause the contents impregnated in the application part to ooze out from the application part, the application part is pressed strongly against the object to be applied, and there is a possibility that more content than necessary may be sprayed.
In addition, a central passage passing through the application section is provided, and the contents are impregnated outward from the central passage into the application area in a short period of time, but some of the contents are unintentionally sprayed directly from the central passage onto the object to be coated. There is also a risk that the contents may hit the object to be coated, scattering into the air, and being accidentally inhaled.

The present invention solves the above-mentioned problems, has a simple configuration, does not require the content to be stored in the actuator, can prevent the content from being unintentionally sprayed directly onto the application target, and can prevent the content from being sprayed directly onto the application target. It is an object of the present invention to provide an actuator for an aerosol container that can apply a liquid content to an object to be coated without spraying the content.

An actuator for an aerosol container according to the present invention has a push button capable of injecting contents and an applicator part capable of applying the injected contents to an application target, and the push button is attached to a container opening of an aerosol container body. An actuator for an aerosol container configured to be connected to a stem provided at an upper part, wherein the push button includes a button body, a stem connection base connecting the button body to the stem, and the button body. and an application part connection base that connects the application part to the application part, the stem connection base has at least one passage hole that communicates from the stem side to the application part side, and the application part has an application part connection base that connects the application part to the application part. and an application surface that applies the contents to the application target, and the application section transfers the contents sprayed from the stem from the outside of the mounting surface to the outside of the application surface when spraying. The applicator is attached to the button body , and the stem connection base is separate from the button body and is movable up and down independently of the button body. By doing so, the above problem is solved.

According to the actuator for an aerosol container according to claim 1, the applicator is connected to the push button via the applicator connection base, and the mounting surface of the applicator is configured to transfer the contents injected from the stem to the mounting surface at the time of injection. Because the push button is constructed so that it can pass through from the outside to the outside of the coating surface, the contents do not accumulate inside the pushbutton, and the contents can quickly reach the coating surface. The time difference until the contents can be applied can be significantly shortened.
In addition, since the contents do not accumulate inside the pushbutton, there is less residual liquid that is wasted inside the pushbutton, and the contents do not deteriorate inside the pushbutton, and the passage hole prevents the remaining liquid from drying out. There is no possibility of blockage caused by components.
Furthermore, since the application part is configured so that the contents reach the application surface by passing through the mounting surface, there are no holes through which the contents can be directly sprayed, and the contents can be unintentionally sprayed directly. There is no risk of spraying or dispersing the contents into the air over a wide area.
In addition, since the stem connection base is constructed separately from the button body, there is no need to change the design of the entire aerosol container actuator to match the shape of the stem, and it is only necessary to change the design of the stem connection base. Common parts can be used except for the base, reducing mold production costs and simplifying inventory management.
In addition, the applicator is attached to the button body , and the stem connection base is constructed separately from the button body and is configured to be movable up and down independently of the button body, so that the button body can be viewed from the side. Even if a shock or unexpected force is applied, no load is applied to the stem, and unless the stem connection base is pressed through the coating surface, the stem will not be pushed down and the contents will not be sprayed, thus preventing accidental spraying. can be prevented.
In addition, since the content is sprayed by pressing the stem connection base over the coating surface, the content is sprayed only when the coating surface is in close contact with the coating target. This eliminates waste such as overspraying the contents.

According to the configuration described in claim 2, since the applicator is configured to be detachable, it can be used as needed, such as injecting the contents directly onto the object to be applied or in spraying the contents in a space. You can change the application and spray form by attaching and detaching the applicator.
Furthermore, when you want to change the specifications of the applicator, or when you want to replace the applicator because it is dirty, etc., you can easily remove the applicator and attach the desired applicator.
According to the configuration described in claim 3, the passage hole is provided with an injection port capable of spraying a mist toward the mounting surface. This makes it easier to uniformly apply the contents to the object to be coated.

According to the configuration described in claim 4, the surface of the stem connection base facing the mounting surface is provided with a passage groove that communicates with the passage hole and is open to the mounting surface side, so that the shape of the passage groove is By adjusting the width and length, the contents can be made to reach the outside of the application surface from a wide range outside the mounting surface, making it easier to apply the contents more uniformly to the object to be applied.
According to the configuration described in claim 5, since the passage hole is branched into a plurality of parts from the stem side toward the application section side, the contents can be dispersed and sprayed over a wide range on the mounting surface side. By adjusting the branching of the coating, it is possible to evenly distribute the contents to the outside of the coating surface.

According to the configuration described in claim 6 , the applicator connection base and the button body are connected via the hinge, and the applicator connection base is configured to be openable and closable from the button body around the hinge. , the passage hole side can be exposed, and for example, by providing an injection port at the tip of the passage hole, it is possible to switch to a form in which the contents are sprayed from the injection port into the object to be coated or into the space in a desired injection form. .
In addition, since the applicator connection base and the button body are hinge-connected, when the applicator connection base is removed from the button body, the applicator connection base will not be lost, and the applicator unit will be attached to the button body again. When installing the connection base, there is no need to install it in the wrong direction.

FIG. 4 is a cross-sectional view showing a spraying state of an aerosol product P including an aerosol container actuator 400 according to another embodiment of the present invention.

An actuator 100 for an aerosol container according to a reference example of the present invention will be described below based on the drawings.
As shown in FIGS. 1 to 4, the aerosol container actuator 100 is connected to a stem S provided at the upper part of the container opening of the aerosol container body C, and is connected to the stem S by pressing the stem S downward to release the aerosol. It has a push button 110 that can spray the contents N in the container body C, and an applicator 120 that can apply the contents N sprayed from the stem S to an object to be coated.

The push button 110 has a button body 111, a stem connection base 112 that connects the button body 111 to the stem S, and an applicator connection base 116 that connects the applicator 120 to the button body 111.
The stem connection base 112 is formed separately from the stem fitting part 115 and the button body 111, and is connected to the button body 111 in a fixed relative position, so that the content injected from the stem S It has a passage hole 113 through which the contents N can pass, and a passage groove 114 that communicates with the passage hole 113 and guides the contents N toward the application section 120 side.

The applicator 120 has a mounting surface 121 that is a surface on the button body 111 side, and an applicator surface 122 that applies the content N directly to the application target, and is connected to cover the outer circumferential surface of the applicator connection base 116. By being sandwiched between the applicator connection base 116 and the holding cover 117, the relative positional relationship between the applicator 120 and the button body 111 is fixed.
The application surface 122 is in contact with the upper surface of the stem connection base 112.
Moreover, the applicator 120 is made of thin foamed rubber.
The holding cover 117 is removably engaged with the applicator connection base 116.

The content N is filled in the aerosol container main body C together with a propellant, and when the content N is taken out, it is injected from the stem S together with the propellant.
As for the type of gas used as propellant, the known liquefied and compressed gases commonly used in aerosol products can be used.
Types of liquefied gases used as propellants include, for example, propane, butane, pentane, or liquefied petroleum gas containing these, dimethyl ether, hydrofluoroolefins, hydrofluorocarbons, and compressed gases used as propellants. Examples of the gas include nitrogen, carbon dioxide, compressed air, oxygen, helium, and nitrous oxide, and one or more of these may be used.

Next, the injection and application of the content N using the aerosol container actuator 100 according to the reference example of the present invention will be described based on the drawings.
First, by pressing the aerosol container actuator 100 downward and pushing down the stem S, the contents N in the aerosol container main body C are taken out via the stem S.
The taken out contents N pass through a passage hole 113 communicating with the stem S, and reach a mounting surface 121 in an application section 120 made of foamed rubber via a passage groove 114.

Furthermore, the content N passes through the application section 120 from the mounting surface 121 and quickly reaches the application surface 120 due to the pressure of the propellant in the aerosol container body C and the pressure caused by vaporization and expansion of the propellant injected together with the content N. reach the top.
Here, the content N on the coating surface 122 can be applied to the coating target by bringing the coating surface 122 into contact with the coating target.

At this time, the passage groove 114 is in direct contact with the applicator 120, and the content N can be injected from the passage groove 114 toward the applicator 120, so that the content N does not accumulate in the aerosol container actuator 100. , the contents N can quickly reach the coating surface 122.
This prevents the content N from being retained in the aerosol container actuator 100 for a long time and deteriorating, and the components of the dried content N from sticking to the passage holes 113 and the passage grooves 114, causing them to become clogged. Never happened.

In addition, if the application part 120 is formed sufficiently thin, the content N can reach the application surface 122 from the mounting surface 121 more quickly, so there is a time difference between the injection operation and the time when the content N can be applied to the application target. can be further shortened, and even when the content of liquefied gas is small, the cooling effect due to vaporization and expansion of liquefied gas can be efficiently obtained.
Furthermore, even if the application surface 122 is pressed against the object to be applied to push down the stem S to take out the contents N, the application surface 122 must be pressed against the object to be applied and the contents N must be taken out from inside the aerosol container main body C before the contents N Since the time it takes for the paint to reach the coating surface 122 is short, the usability can be improved.

Furthermore, the injected contents N reach the application surface 122 only by passing through the application part 120, and there is no hole or the like to directly inject the contents N to the outside of the aerosol container actuator 100. This prevents scattering and prevents the content N from being erroneously sprayed onto a target other than the object to be coated, and the content N from being erroneously sucked.
Furthermore, by making the aerosol valve a tilt valve that can open the valve with a force that tilts the stem S toward the side, it is possible to not only press the applicator 120 in the direction of pushing down the stem S, but also push the applicator 120 Even if the content N is applied to the application target by moving in the lateral direction while applying the content N to the application target, the content N in the aerosol container main body C can be taken out from the stem S and transmitted through the application part 120. This improves work efficiency.

Next, aerosol container actuators 200a, 200b, and 300 according to other reference examples of the present invention, and an aerosol container actuator 400 according to an embodiment of the present invention will be described based on FIGS. 5 to 8.
Note that some descriptions of the same configurations as the aerosol container actuator 100 will be omitted.

Thereby, the pressing surface 219 can be provided on the upper surface of the aerosol container actuator 200a, and the stem S can be easily pressed via the aerosol container actuator 200a by pressing the pressing surface 219 without touching the application surface 222, and the contents can be When injecting N, it is possible to press the pressing surface 219 to supply the content N onto the application surface 222, and at the same time easily spread the content N onto the application target without changing the hand of the aerosol container actuator 200a. .
Further, as shown in FIG. 6, in the aerosol container actuator 200a, the applicator connecting base 216 is hinge-connected to the button body 211 by a hinge part 223, and the applicator 220 is connected to the button body 211 from the passage hole 213 together with the applicator connecting base 216. Since it can be separated, by providing an injection port 218 at the tip of the passage hole 213, the content N can be sprayed from the injection port 218 into the object to be coated or into the space in a desired spray form such as a mist or a jet. You can also switch.

Furthermore, if the aerosol container actuator 200b shown in FIG. Injected.
As a result, the contents N can be diffused from the outside of the mounting surface 221 and reach the outside of the application surface 222, and the contents N can be spread quickly over a wide range on the application surface 222 compared to the aerosol container actuator 200a. Since the content N can be supplied evenly over a wide range of areas to be coated, it becomes easier to spread the content N more widely and uniformly.

As shown in FIG. 8, in the aerosol container actuator 300, the passage hole 313 branches into a plurality of parts and communicates with each other toward the mounting surface 321. This allows the content N to be transferred from a wider area of the mounting surface 321 to the application surface. 322, and can improve the efficiency of spreading the content N onto the object to be coated.

As shown in FIG. 9, the aerosol container actuator 400 has a button body 411 that is fixedly connected to the mounting cup M via a fixing member 418, and a stem connection base 412 that is independent of the button body 411. It is formed by
As a result, even if the button body 411 receives an impact or unexpected force from the side, no load will be applied to the stem S, and the stem S will be pushed down unless the stem connection base 412 is pressed through the coating surface 422. Since the contents N will not be injected, erroneous injection can be prevented.

Furthermore, since the content N is sprayed by pressing the stem connection base 412 over the coating surface 422, the content N is sprayed only when the coating surface 422 is in close contact with the coating target, and the content N is sprayed onto the coating target. The application operation and the removal operation of the contents N are integrated, so that there is no waste such as overspraying of the contents N.
