  The actuator 1 has a fixing member 10 that aligns and fixes the pair of aerosol cans 3 in parallel. The fixing member 10 is also referred to as a fixing board, and the respective aerosol cans 3 are fixed to the fixing member 10 at the portion of the mounting cup 3b by means such as fitting or undercut, and assembled in a parallel juxtaposed state .

  The shape and the like of the fixing member 10 can be changed variously as long as the pair of aerosol cans 3 can be arranged in parallel and fixed. The portions of the container body 3a of the pair of aerosol cans 3 may be integrally packaged with a shrink film or the like.

  As shown in FIGS. 1 and 2, the actuator 1 includes a nozzle body 11 for discharging the contents discharged from the stem 3 c of each aerosol can 3 to the outside.

  As shown in FIGS. 3A to 3C, the nozzle body 11 in the present embodiment integrally forms the upper member 11b and the lower member 11c via a pair of thin hinge portions 11a. The upper member 11b and the lower member 11c are fitted together by bending along the hinge portion 11a to form the configuration shown in FIGS.

  The lower member 11c of the nozzle body 11 is provided with a pair of stem connection portions 12 each formed in a cylindrical shape, fitted to the tip of the stem 3c of each aerosol can 3 and connected to the stem 3c. Further, the upper member 11b of the nozzle body 11 is provided with a cylindrical portion 13 for fittingly fixing the nozzle member 14 constituting the nozzle portion.

  In the present embodiment, the nozzle member 14 is formed separately from the nozzle body 11 and is fitted and fixed to the cylindrical portion 13. However, the nozzle member 14 is formed integrally with the nozzle body 11. The configuration can also be made. Moreover, the cross-sectional shape of the nozzle member 14 is not limited to a substantially elliptical shape, and may be another cross-sectional shape such as a circular shape or a rectangular shape, for example.

  The nozzle body 11 is a flow path of the contents that causes the respective stem connection portions 12 and the cylindrical portion 13 to communicate between the upper member 11 b and the lower member 11 c in a state where the upper member 11 b and the lower member 11 c are fitted. Section. Thus, the stems 3 c of the respective aerosol cans 3 communicate with the nozzle member 14 through the stem connection portion 12 and the flow passage in the nozzle body 11.

  The pair of hinges 11 a is provided at the tip of the plate-like portion 20 extending horizontally toward the rear side of the nozzle body 11 (the opposite side of the cylindrical portion 13). The nozzle body 11 has a plate-like stopper portion 15 horizontally extending rearward from the upper member 11b, and the stopper portion 15 is a pair of hinge portions 11a by pillar portions 16 depending from the left and right edge portions. It connects with the plate-like part 20 which continues in the

  On the left and right sides sandwiching the cylindrical portion 13 provided on the upper member 11 b of the nozzle body 11, a pressing contact wall 17 standing upward from the top surface 11 d is provided. By applying a force, the nozzle body 11 can be pushed downward (in a direction in which the stem 3c is pushed down to the container body 3a). Further, a projecting portion 18 as a guided portion is integrally provided on the abutting wall 17 so as to protrude outward from the side surface, and a guide projection 19 projecting outward is formed on the outer surface 18 a of the projecting portion 18. Is provided. The protrusion 18 and the guide protrusion 19 are erected from the top surface 11 d of the nozzle body 11 and formed in a substantially T shape in a plan view. In the present embodiment, the protrusion 18 and the guide protrusion 19 are provided integrally with the contact wall 17 in order to increase the rigidity, but the present invention is not limited to this. It is good.

  A cover body 21 disposed outside so as to cover the fixing member 10 and the nozzle body 11 is attached to the pair of aerosol cans 3. The cover body 21 is detachably mounted to the fixing member 10 by means such as fitting or undercutting. The cover body 21 includes a lower end portion 21a surrounding the fixing member 10 and the tip end side portions of the pair of aerosol cans 3 and an upper end portion 21b connected via a shoulder above the lower end portion 21a. Note that, as shown in FIG. 1, the cover body 21 may be provided with an over cap 40 covering the upper end portion 21 b of the cover body 21 including the tip end portion of the nozzle member 14. By attaching the overcap 40 to the cover body 21 at the time of distribution or the like, it is possible to prevent the erroneous operation of the operation piece 28 or the intrusion of foreign matter into the inside of the nozzle member 14 or the like.

  The upper portion 21 b of the cover body 21 has a side peripheral wall 22 surrounding the nozzle body 11 and a top wall 23 connected to an upper portion of the side peripheral wall 22. A front opening 24 for causing the nozzle member 14 to project forward is formed on the front side of the side peripheral wall 22, and a rear opening 25 is formed on the rear side. Further, above the front opening 24, an operation piece 28 swingably connected to the top wall 23 through a hinge portion 27 is provided. The operation piece 28 has a plate-like portion 29 curved slightly upward and laterally, and a reinforcing flange 30 extending downward is integrally provided on the periphery of the plate-like portion 29. . Further, as shown in FIG. 2, the operation piece 28 is disposed above the nozzle body 11, and the lower surface of the flange 30 is opposed to the contact wall 17 of the nozzle body 11 at a predetermined interval.

  Furthermore, as shown in FIG. 4, a pair of guide walls 31 hanging from the top wall 23 is provided on both left and right sides of the operation piece 28 of the cover body 21, and each guide wall 31 has a stem 3 c. A guide groove 32 extending in a direction (vertical direction) parallel to the push-down direction is formed like a notch from the lower edge. As shown in FIGS. 1 and 2, in a state where the actuator 1 is mounted on the aerosol container 2, the outer surface 18 a of the projection 18 provided on the nozzle body 11 is slidably opposed to the inner surface 31 a of the guide wall 31. ing. Further, the guide projection 19 provided on the outer surface 18 a of the projection 18 is slidably fitted in the guide groove 32. Thereby, when pushing down the nozzle body 11, while the guide protrusion 19 moves along the guide groove 32, the outer surfaces 18a of the pair of projecting portions 18 move along the inner surfaces 31a of the opposing guide walls 31, respectively. . That is, in the nozzle body 11, the displacement in the left and right direction is restricted by the outer surfaces 18 a of the pair of projecting portions 18 being pinched in the left and right direction by the inner surfaces 31 a of the guide wall 31. The displacement in the front-rear direction is limited by being sandwiched between

  Here, as an example of a method of setting the actuator 1 having the above configuration to the aerosol container 2, the aerosol container in which the fixing member 10 is attached in advance in a provisionally set state in which the nozzle body 11 is inserted from below the cover body 21 and assembled. The cover body 21 is set from above with respect to No. 2 so as to cover it. In the present embodiment, when temporarily setting the nozzle body 11 to the cover body 21, the outer surfaces 18 a of the pair of projecting portions 18 provided on the nozzle body 11 are sandwiched by the inner surfaces 31 a of the opposing guide walls 31. By fitting the guide projections 19 into the guide grooves 32, alignment can be performed in the front, rear, left, and right. Thereby, the stability of the nozzle body 11 at the time of temporary setting can be improved. Although the nozzle member 14 can be temporarily set after being attached to the cylindrical portion 13 of the nozzle body 11 in advance, the nozzle body 11 can be inserted from the viewpoint of smoothly inserting the nozzle body 11 into the cover body 21. It is preferable to mount the nozzle member 14 after being inserted inside the cover body 21.

  Further, in the present embodiment, when the nozzle body 11 is assembled to the cover body 21, the nozzle member 14 (or the cylindrical portion 13) is placed on the lower end 24 a of the front opening 24 and the stopper portion 15. Can be placed on the lower end 25 a of the opening edge of the rear opening 25. Thereby, it is possible to prevent the nozzle body 11 from falling off from the cover body 21 in the temporarily set state, and it becomes possible to more easily attach the aerosol container 2 to the aerosol container 2.

  When discharging the contents of the aerosol container 2 using the actuator 1 having the above configuration, as shown in FIG. 5, the lower surface of the flange 30 is brought into contact with the contact wall 17 by depressing the operation piece 28 Push the body 11 downwards. By pushing the nozzle body 11 downward, the stem 3c of each aerosol can 3 can be simultaneously pushed downward, and the contents can be discharged from each stem 3c. The contents discharged from the stems 3c join together at the nozzle member 14 through the flow path in the nozzle body 11, and are discharged from the tip of the nozzle member 14 to the outside. As described above, by depressing the nozzle body 11, the two types of contents contained in the two aerosol cans 3 are simultaneously discharged from the nozzle member 14 to the outside.

  As described above, the nozzle body 11 is limited in displacement in the left-right direction by the outer surfaces 18 a of the pair of protrusions 18 being pinched in the left-right direction by the inner surface 31 a of the guide wall 31. Displacement in the longitudinal direction is restricted by being pinched in the longitudinal direction, and the stem 3c of each aerosol can 3 is moved in the depression direction of each stem 3c in order to move straight downward in a stable state. It is possible to apply force straight. Thus, the stem 3c can be pushed down smoothly. Therefore, the operability at the time of discharging the contents from the aerosol container 2 equipped with the stem 3c can be improved by using the actuator 1 of the present invention. Further, since a force is applied to the stem 3c in a straight direction along the depressing direction, no extra load is applied.

  Further, as in the present embodiment, in the case where the aerosol container 2 is configured by two aerosol cans 3 arranged side by side in parallel, the balance between the left and the right is simultaneously performed when the pair of stems 3 c is pushed down simultaneously by the nozzle body 11. Since the actuator 1 of the present invention can limit the displacement of the nozzle body 11 in the left-right direction when the nozzle body 11 is easily deformed in the horizontal direction, the aerosol container having such a pair of stems 3c 2 is more effective.

  Further, in the present embodiment, when the stem 3c is pushed down to the push-off position, when it is further pushed down by the operation piece 28, the upper surface of the stopper portion 15 abuts on the lower end portion of the operation piece 28 And the lower displacement of the operation piece 28 is limited. Therefore, the amount of depression of the operation piece 28 can be limited to an appropriate range by the stopper portion 15. As a result, it is possible to prevent the operation piece 28 from being bent excessively and causing plastic deformation in the operation piece 28 or an unnecessary load on the hinge portion 27. In addition, the user can easily grasp that the stem 3c is pushed down to the push-off position by the touch when the operation piece 28 contacts the stopper portion 15.

  Furthermore, by supporting and reinforcing the stopper portion 15 from below with the column portion 16 and the plate portion 20, the strength of the stopper portion 15 can be enhanced, and the deformation suppressing function of the operation piece 28 can be improved.

  It is needless to say that the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention.

  For example, in the above embodiment, although the aerosol container 2 is configured to have a pair of aerosol cans 3 each having a stem 3c, the present invention is not limited to this, and one aerosol can can be contained in the container body. It is also possible to use a single type container having two housing spaces and provided with a pair of stems corresponding to the respective housing spaces in the mounting cup, or a single type of aerosol can having one stem.
