Description

  The present invention relates to an actuator for an aerosol container. In particular, the present invention relates to an aerosol container actuator that can be switched to a normal injection state, an erroneous injection prevention (lock) state, and an injection maintenance state (gas release state) with a simple operation.

Generally, when a used aerosol container is discarded as garbage, a gas remaining inside the container must be released. Therefore, various degassing mechanisms for aerosol containers have been proposed.
For example, in an actuator for an aerosol container, a stopper is provided on the upper surface of a push button with a nozzle connected to the stem of the container, and the stopper is engaged with the cover by moving the stopper while pressing down the push button, whereby the push button is pressed. It is known that the push button is kept pressed down even if the finger is released, and the gas continues to be ejected to release the residual gas inside the container (see Patent Document 1 and the like).
On the other hand, in addition to the above-described configuration for degassing, there is known an aerosol container actuator having an erroneous injection prevention mechanism for restricting depression of a stem when a user accidentally presses a push button. (See Patent Document 2, etc.). In the aerosol container disclosed in Patent Literature 2, when the slidable moving member slides in the direction in which the nozzle falls, the tilt regulating portion of the fixed member fits into the inner peripheral surface of the through hole of the moving member. The result is an obstruction member for preventing the nozzle from falling down, so that the contents are prevented from being jetted.
In addition, an aerosol container actuator that can switch the degassing state and the erroneous injection prevention state from the normal injection state with one touch has been proposed (see Patent Document 3 and the like). In the aerosol container actuator disclosed in Patent Literature 3, the operation button is slid in one of the front and rear directions with respect to the cover without being pressed down, thereby being engaged with the cover to prevent the operation button from moving downward. As a result, the contents are not ejected and the operation is prevented from being erroneously ejected.While the operation button is pressed down and the cover is slid to the other side in the front-rear direction, the operation button is prevented from moving upward by being engaged with the cover. It is configured so that the gas keeps blowing.

In the aerosol container actuator provided with both the degassing mechanism and the erroneous injection prevention mechanism known in Patent Literature 2, Patent Literature 3, etc., degassing is an operation which is usually performed only before disposal of the aerosol container. The operation to shift to the degassing state is similar to the operation to shift to the erroneous injection prevention state (sliding direction is only the difference in the front-rear direction, etc.). May be performed.
Further, in the aerosol container actuator provided with both the gas venting mechanism and the erroneous injection preventing mechanism, there is a great restriction on the design in view of the fact that a multi-function is mounted using a guide rail or the like.
As described above, there is a demand for an aerosol container actuator having a high degree of freedom in design, such as an asymmetric actuator.

  The present invention has been made to solve the above problems, and has as its object to realize a gas venting mechanism and an erroneous injection preventing mechanism with a high degree of freedom in design design, a simple configuration, and a simple operation. Can be switched between the normal injection state and the erroneous injection prevention state, and can be switched to the degassing state (injection maintenance state) by a separate operation from the switching operation between the normal injection state and the erroneous injection prevention state to suppress erroneous operations Accordingly, it is an object of the present invention to provide an aerosol container actuator which can obtain high convenience.

The aerosol container actuator of the present invention, a shoulder cover attached around a stem provided at the upper portion of the container mouth of the aerosol container body, a push button connected to the stem and capable of pressing the stem downward, An aerosol container actuator having a button cover mounted on the shoulder cover so as to surround the push button, and a button cap provided on the push button so as to press the push button downward,
The button cover and the push button have a rotation engagement mechanism that is engaged by being rotated,
The button cover and the button cap have a cap engagement mechanism that is engaged by moving the button cap,
The rotation engagement mechanism is formed so as to prevent downward movement from a position before the push button is pressed down when engaged.
The object is achieved by the cap engagement mechanism being formed so as to prevent the push button from moving upward from the depressed position when engaged.

According to the aerosol container actuator according to the first aspect of the present invention and the aerosol product according to the thirteenth aspect of the present invention, the push button and the button cover are provided with the rotation engagement mechanism, and the button cover and the button cap are provided with caps. With the simple configuration of providing the engagement mechanism, both the gas release mechanism and the erroneous injection prevention mechanism can be realized. In addition, since the cap engagement mechanism can be realized by a button cap provided on the push button and a button cover surrounding only a part of the side peripheral surface of the push button, the cap engaging mechanism has a shape corresponding to the shape of the button cover and the size of the push button. Regulations are small and a high degree of design freedom is obtained.
Furthermore, it is possible to switch between the normal injection state and the erroneous injection prevention state only by rotating the button cover, and to switch between the normal injection state and the injection maintaining state (gas release state) only by moving the button cap. Since it is possible, the operation by the operator is easy. Further, the switching from the normal injection state to the erroneous injection prevention state and the switching from the normal injection state to the injection maintaining state are performed by operating separate members, so that occurrence of erroneous operation can be suppressed. Unintended transition to the degassing state can be suppressed, and high convenience can be obtained.

According to the configuration described in claim 2 of the present invention, the circumferential position of the pressing restraining projection is displaced from the position corresponding to the slit of the leg by the rotation of the button cover, and the position other than the slit of the leg of the push button is changed. The lower part of the pushbutton can be inserted under the lower part of the pushbutton, so that the lower part of the pushbutton can be prevented from moving downward. Since the movement is prevented, the operation by the operator becomes easier, and the convenience is further improved.
According to the configuration of the third aspect of the present invention, the ear portion is engaged with the engaging projection protruding above the button cover by the movement of the button cap, thereby preventing the push button from moving upward. Can be. Therefore, since the degassing state can be reliably obtained by a simple configuration in which the engagement projection is provided on the upper part of the button cover, if the engagement projection can be engaged with the ear, it is necessary to manufacture the button. No precise positioning or dimensional alignment is required, and an aerosol container actuator can be manufactured in a simple manufacturing process at low cost.
According to the configuration described in claim 4 of the present invention, the button cap can be moved more stably, the operation by the operator becomes easier, and the convenience is further improved.
According to the configuration described in claim 5 of the present invention, the movement of the button cap can be performed by rotation, the operation by the operator becomes easier, and the convenience is further improved.
According to the configuration described in claim 6 of the present invention, the button cap rotates following the button cover when the rotation engagement mechanism operates, so that occurrence of erroneous operation can be further suppressed, and high convenience is achieved. Is obtained.
According to the configuration described in claim 7 of the present invention, since the housing portion surrounds only a part of the push button, a high degree of freedom in design design can be obtained for the exposed portion of the push button.
According to the configuration described in claim 8 of the present invention, it is possible to visually recognize that the erroneous injection prevention state is set, so that the convenience is further improved.

According to the configuration of the ninth aspect of the present invention, a high left-right asymmetrical design is obtained when viewed from the front.
According to the tenth and eleventh aspects of the present invention, the rotation range in one direction and the other direction of the button cover is limited by the restriction member of the shoulder cover serving as an obstruction member, and the Since excessive rotation is automatically suppressed, the operator can easily recognize that the normal injection state has been switched to the erroneous injection prevention state or the injection maintenance state (gas release state), and the convenience is further improved.
According to the configuration described in claim 12 of the present invention, since the movement of the push button in the circumferential direction is prohibited by the shoulder cover, the operation of turning the button cover and moving the button cap by the operator becomes easier. The convenience is further improved.

Hereinafter, the present invention will be described in detail.
[Aerosol container actuator]
As shown in FIG. 1, the aerosol container actuator 110 of the present invention includes a shoulder cover 130 which is attached to a mounting cup 103 on an upper portion of an aerosol container main body 101 so as to surround a stem 102 provided at a central portion thereof. A push button 150 connected to the stem 102 and capable of pressing the stem 102 downward; a button cover 120 mounted on the shoulder cover 130 so as to surround the push button 150; and the push button 150 can be pressed downward on the push button 150 And a button cap 160 provided at the bottom.
The button cover 120 is configured to be rotatable in the circumferential direction with respect to the shoulder cover 130.
The button cap 160 is configured to be integrally movable with the rotation of the button cover 120 at a position where the push button 150 does not push down the stem 102.
The push button 150 is connected to the stem 102 and is configured to be integrally movable with the stem 102 only in the vertical direction.
In addition, "upper" and "lower" described in the specification and the claims are directions generally recognized by an operator, and "up and down" is "up" with the stem side of the aerosol container main body. Direction. Further, the “circumferential direction” is a direction of orbiting about the “vertical direction” as an axis. “Front” is the direction in which the contents are ejected from the nozzle portion when the push button is fitted to the stem.

The position where the push button 150 can move vertically with respect to the button cover 120 is in a normal ejection state. When the upper surface of the button cap 160 provided on the upper surface of the push button 150 is pressed downward, the stem 102 moves downward. When pushed down, the contents of the aerosol product 100 are ejected from the stem 102 through the nozzle portion 159 of the push button 150 to the outside, and when the push button 150 is released, the stem 102 returns upward and the push button 150 is released. Is automatically pushed upward, and the ejection of the contents is stopped.
In the aerosol container actuator 110 of the present invention, the button cover 120 and the push button 150 are provided with a rotation engagement mechanism. In the rotation engagement mechanism, in the normal ejection state, and in a state in which the push button 150 is positioned above (the stem 102 is not pressed and the ejection of the contents is stopped), the button cover 120 is attached to the push button 150. On the other hand, it is rotatable in the circumferential direction, and at the position rotated in the circumferential direction, the push button 150 is prevented from being pushed down, and the erroneous injection is prevented (locked) in which the pressing of the stem 102 is prevented.
On the other hand, the button cover 120 and the button cap 160 are provided with a cap engagement mechanism. In the cap engagement mechanism, in the normal ejection state, and in the state where the push button 150 is located below (the stem 102 is pressed downward and the contents are ejected), the button cap 160 is The push button 150 is prevented from being pushed upward at the position where the push button 150 is rotated and engaged in the rotational engagement, and the injection maintaining state (gas release state) is maintained while the stem 102 is kept pressed.

  With such a configuration, the degassing mechanism and the erroneous injection can be achieved by a simple configuration in which the push button 150 and the button cover 120 are provided with the rotation engagement mechanism and the button cover 120 and the button cap 160 are provided with the cap engagement mechanism. Both prevention mechanisms can be implemented. Further, since the cap engagement mechanism can be realized by the button cap 160 provided on the push button 150 and the button cover 120 surrounding only a part of the side peripheral surface of the push button 150, the shape of the button cover 120 and the push The restriction on the size of the button 150 is small, and a high degree of design freedom is obtained. Further, it is possible to switch between the normal injection state and the erroneous injection prevention state only by rotating the button cover 120, and to switch between the normal injection state and the injection maintenance state (gas release state) only by moving the button cap 160. Since it is possible, the operation by the operator is easy. Furthermore, since the switching from the normal injection state to the erroneous injection prevention state and the switching from the normal injection state to the injection maintaining state are performed by operating separate members, occurrence of erroneous operation can be suppressed, High convenience is obtained.

Hereinafter, the detailed configuration and operation of the aerosol container actuator 110 according to one embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, an aerosol container actuator 110 according to an embodiment of the present invention is mounted on a mounting cup 103 on an upper portion of an aerosol container main body 101 so as to be attached around a stem 102 provided at a central portion thereof.

I have. The first regulating member 136 and the second regulating member 137 are formed so as to be separated from each other so as to form an opening angle of about 250 degrees in plan view.
Buttons to be described later are provided on the wide-angle ends (ends facing the opening angle of about 250 degrees) 136a and 137a of the first regulating member 136 and the second regulating member 137 in the inner jaw 134, respectively. Click pieces 139a and 139b are formed, respectively, which project slightly inward in the radial direction at intervals corresponding to the widths of the pressing restraining projections 124a and 124b of the cover 120.
The second regulating member 137 has a locking rib 137b extending upward from the tip thereof, and the locking rib 137b is used to lock a locking ridge 155 of a push button 150 described later. An engaging slit 137c extending vertically is formed.

As shown in FIG. 3, the push button 150 includes a disk-shaped ceiling 151, a cylindrical leg 152 extending downward from an outer peripheral edge of the ceiling 151, and an aerosol product provided inside the leg 152. And a nozzle unit 159 for injecting the contents of 100 to the outside.
The leg 152 is formed with two slits 153a and 153b that are open downward and extend in the vertical direction. The slits 153a and 153b are formed such that one slit 153a is formed at a position close to the nozzle portion 159, and the other slit 153b forms an opening angle of about 115 degrees with the one slit 153a in plan view. It is formed apart.
A fitting receiving portion 154 that engages with the fitting protrusion 161 of the button cap 160 is formed at the center of the ceiling 151.
On the surface of the ceiling 151, one regulating protrusion 156 protruding upward is formed at a position close to the injection port 159d of the nozzle part 159, and the other regulating protrusion 157 protruding upward has one regulating protrusion. The protrusion 156 is formed so as to be separated from the protrusion 156 so as to form an opening angle of about 90 degrees in plan view. By forming the regulating protrusions 156 and 157 in this manner, the maximum rotation angle of the button cap 160 is regulated to about 90 degrees.
The leg 152 has a vertically extending locking ridge that engages with an engagement slit 137c formed in a locking rib 137b of the second regulating member 137 of the second cover member 137 of the shoulder cover 130 on its inner peripheral surface. 155 are formed. The locking protrusion 155 is formed so as to have an opening angle of about 115 degrees with the slit 153a and about 130 degrees with the slit 153b.

The nozzle portion 159 of the push button 150 surrounds the outer cylindrical cylindrical hole 159a fitted to the stem 102, the discharge portion 159b extending forward from the stem hole 159a, and surrounds the discharge portion 159b. It has a tapered surrounding wall 159c which has a large diameter and is continuously and integrally exposed to the opening 152a of the leg 152.
An ejection port 159d is provided at the tip of the discharge section 159b, and a conduction hole 159e for guiding contents ejected from the tip of the stem 102 to the ejection port 159d is formed inside the stem hole 159a and the ejection section 159b. .
The stem hole 159a is formed in a shape (cylindrical shape in the present embodiment) that is fitted into the stem 102 and is vertically and slidably guided back and forth and right and left without play.

As shown in FIG. 4, the button cover 120 includes a lower ring portion 121 that can accommodate the push button 150 in the center, and a part of the lower ring portion 121 (when the push button 150 is viewed from the front in a normal ejection state). And a housing part 125 that can rise upward from the injection port 159d (left side) and open and partially surround the side peripheral surface of the push button 150.
On the back side of the lower ring portion 121, a rotation guide groove 122 is formed which is capable of engaging the rotation guide rail 131 of the shoulder cover 130 and rotating the button cover 120 in the circumferential direction with respect to the shoulder cover 130.
A recess 127 is formed in a region of the lower ring 121 that is close to the injection port 159d of the push button 150 in the normal injection state so as to obtain a predetermined injection angle.
In the lower ring portion 121, two pressing restraining projections 124a and 124b projecting radially inward and extending downward respectively fit with the two slits 153a and 153b of the leg 152 of the push button 150 in the normal injection state. It is formed at a position (a position immediately below the slits 153a, 153b).
An engagement protrusion 123 is formed on an upper portion of the housing portion 125 so that the ear portion 167 of the button cap 160 can be fitted directly below the push button 150 only when the push button 150 is in a position where the push button 150 is pushed down. I have.

As shown in FIG. 5, the button cap 160 has a substantially disk shape rotatably provided on the push button 150, and has a rotating top plate 162 having a fitting protrusion 161 formed on the center rear side, An operation protrusion 163 that can be operated by a finger and protrudes downward from the outer peripheral edge of the rotating top plate 162 so as to surround the push button 150 is provided.
At the position where the push button 150 is not depressed, a notch 166 is formed on the rotary top plate 162 so as to conform to the outer shape of the engaging projection 123 formed on the upper part of the housing portion 125 of the button cover 120. A region (hatched portion in FIG. 5B) adjacent to the notch 166 on the outer peripheral edge of the rotating top plate 162 is an ear portion 167 that can be fitted under the engagement protrusion 123 of the housing portion 125. The ear 167 is a region on the downstream side in the rotation direction of the rotating top plate 162. The protruding end 167a of the ear 167, which is continuous with the notch 166, is formed at an obtuse angle so that it can be easily fitted under the engagement protrusion 123 when the button cover 120 is engaged with the engagement protrusion 123.
The operation projection 163 is formed at a position where an opening angle of 150 degrees is formed with the projection 167a of the ear 167.
A rotation restricting member 164 is formed on the rotary top plate 162 so as to project radially outward from the outer peripheral edge of the fitting projection 161 in the same direction as the operation projection 163.

The operation and action of the aerosol container actuator 110 according to one embodiment of the present invention configured as described above will be described.
In the aerosol container actuator 110, as shown in FIG. 1, the shoulder cover 130 is fixedly attached to the mounting cup 103 on the upper part of the aerosol container main body 101 of the aerosol product 100, and the push button 150 has the stem hole 159a. The button cover 120 is connected to the stem 102 by being fitted to the upper portion of the stem 102 extending upward from the mounting cup 103, and the button cover 120 rotates the rotation guide groove 122 of the lower ring portion 121 on the rotation guide rail 131 of the shoulder cover 130. The button cap 160 is mounted on the push button 150 by fitting the fitting protrusion 161 to the fitting receiving portion 154 of the push button 150, and thus the button cap 160 is configured to be usable.
The push button 150 is prohibited from moving in the circumferential direction when the locking ridge 155 is locked in the engagement slit 137c of the second regulating member 137 of the shoulder cover 130.
At this time, the housing 125 of the button cover 120 is located only to the left of the push button 150 when viewed from the front. Further, the notch 166 of the button cap 160 is engaged with the engagement protrusion 123 of the housing 125 of the button cover 120 in the horizontal direction. Further, the injection port 159d of the push button 150 can be visually recognized from the front.

(Normal injection state)
When the operator injects the contents of the aerosol product 100 in normal use and stops the injection, the rotational positional relationship between the push button 150 and the button cover 120 is changed to the normal injection state (FIG. 1 and FIG. 6). (Injection state and injection state).
FIG. 6 shows a state at the time of injection when the push button 150 is pressed downward, and FIG. 1 shows a state at the time of injection stop when the push button 150 is returned upward.
As shown in FIG. 7A, in the rotational positional relationship in the normal injection state, the pressing restraining protrusion 124a of the button cover 120 abuts on the wide-angle end 136a of the first regulating member 136 of the shoulder cover 130. It is in a state. When the push button 150 is moved downward, the press stop protrusion 124a is located at a position where it is fitted to one slit 153a, and at the same time, the other press stop protrusion 124b is located at a position where it is fitted to the other slit 153b. Thus, the vertical movement of the push button 150 is not prevented.
Further, in the rotational positional relationship in the normal ejection state, the rotation restricting member 164 of the button cap 160 is connected to the narrow-angle end 156a of one of the restricting protrusions 156 of the push button 150 (on the side facing the opening angle of about 90 degrees). (See FIG. 1 (f)).

  When the operator pushes down the push button 150 in the rotation position relation in the normal injection state, the stem 102 is pressed downward, and thereby a valve mechanism (not shown) provided inside the mounting cup 103. Is opened, and the contents are injected to the outside from the injection port 159d of the nozzle portion 159. When the operator stops pushing down the push button 150, the push button 150 automatically returns to the neutral position in FIG. 1 by the elastic force of the spring built in the valve.

[Incorrect injection prevention (locked) state]
When the operator prevents the contents of the aerosol product 100 from being ejected due to an erroneous operation or the like, the rotational positional relationship of the button cover 120 with respect to the push button 150 is set to the erroneous ejection prevention (lock) state shown in FIG. used.
As shown in FIG. 7B, the erroneous injection prevention (lock) state is such that the button cover 120 is moved to the right (upward) from the state at the time of the injection stoppage in which the push button 150 shown in FIG. (In a counterclockwise direction as viewed from above), the shift can be made. In this rotational positional relationship, the positions of the depression suppressing protrusions 124a and 124b of the button cover 120 are displaced from the positions corresponding to the slits 153a and 153b. The push button 150 is moved downward by entering under the portions other than the slits 153a and 153b of the leg portion 152 constituting the rotary engagement mechanism of the push button 150, and the push stop projections 124a and 124b serving as obstructing members. Is prevented. At this time, the lower end surfaces of the leg portions 152 of the push button 150 are in contact with the upper end surfaces of the press-down preventing protrusions 124a and 124b of the button cover 120.
Accordingly, even if the push button 150 is pressed by mistake, the push button 150 does not move downward, thereby preventing the contents from spouting unexpectedly.
When the button cover 120 is rotated about 90 degrees to the right (counterclockwise as viewed from above) from the normal ejection state, the pressing restraining projection 124b contacts the wide-angle end 137a of the second regulating member 137 of the shoulder cover 130. The movement is stopped. At this time, the fact that the pressing restraining protrusion 124b of the button cover 120 abuts on the wide-angle end 137a of the second regulating member 137 is tactilely transmitted to the operator as a click feeling by getting over the click piece 139b in the middle. Is done.
In the button cap 160, the notch 166 of the rotating top plate 162 of the button cap 160 is engaged with the engaging projection 123 on the upper part of the housing portion 125 of the button cover 120 in the horizontal direction due to shape adaptation. When the button cover 120 is not pressed down, the button cover 120 rotates integrally.
In this rotational position relationship in the erroneous injection preventing (locked) state, the rotation restricting member 164 of the button cap 160 is brought into contact with the narrow-angle end 157a of the other restricting projection 157 of the push button 150. Even if the button cover 120 does not rotate to about 90 degrees, the erroneous injection is prevented (locked) if the pressing restraining projections 124a and 124b are in contact with the lower end surfaces of the legs 152.
In the rotational position relationship in the erroneous injection prevention (locked) state, the housing portion 125 of the button cover 120 covers the injection port 159d of the nozzle portion 159, and the injection port 159d cannot be visually recognized from the front.

  When the button cover 120 is rotated about 90 degrees to the left (clockwise as viewed from above) in order to release the erroneous injection prevention (lock) state, the pressing restraining protrusion 124 a is moved to the wide angle of the first regulating member 136 of the shoulder cover 130. Movement is stopped by contacting the end 136a. At this time, the fact that the pressing restraining projection 124a of the button cover 120 abuts on the wide-angle end 136a of the first regulating member 136 is tactilely transmitted to the operator as a click feeling by getting over the click piece 139a in the middle. Is done.

[Injection maintenance (gas release) state]
When the operator discharges the gas remaining inside the used aerosol container body 101, the position relationship between the button cover 120 and the button cap 160 at the position where the push button 150 pushes down the stem 102 is shown in FIG. Is used as the injection maintenance (gas release) state shown in FIG.
The injection maintaining (gas releasing) state is such that the button cap 160 is moved rightward (counterclockwise as viewed from above) from the state at the time of the injection in which the push button 150 shown in FIG. By rotating, the ear 167 constituting the cap engaging mechanism of the button cap 160 is inserted below the engaging projection 123 of the housing 125 of the button cover 120 in this rotational positional relationship. Engage and prevent push button 150 from moving upward. The rotation restricting member 164 of the button cap 160 is shifted rightward from the state at the time of ejection (the state in which the rotation restricting member 164 is in contact with the narrow-angle end 156a of the one restricting projection 156 on the ceiling 151 of the push button 150) ( When rotated about 90 degrees in the counterclockwise direction as viewed from above, the push button 150 comes into contact with the narrow-angle end 157a of the other regulating protrusion 157 on the ceiling 151 of the push button 150, and the movement is stopped. Even if the button cap 160 does not rotate to about 90 degrees, if the ear 167 is engaged with the engagement protrusion 123 of the button cover 120 to some extent, the injection is maintained (gas release).
As described above, even if the operator releases his / her hand, the state in which the stem 102 is pressed downward by the push button 150 and the content (residual gas) is ejected can be maintained, so that the inside of the aerosol container main body 101 can be easily formed. Residual gas can be released.
