  Hereinafter, the present invention will be described in detail with reference to the drawings.

  A double aerosol actuator (discharge tool) 1 according to an embodiment of the present invention shown in FIGS. 1 to 4 is used for a dual aerosol container 2. The double aerosol container 2 includes a pair of aerosol cans 3.

  Each of the pair of aerosol cans 3 has a structure in which, for example, the outer edge of a metal mounting cup 3b is fastened and fixed to, for example, a metal bottomed cylindrical container body 3a, and is provided on the mounting cup 3b. When the stem 3c thus formed is pushed down toward the inside of the container body 3a, the contents accommodated inside the container body 3a are discharged from the tip of the stem 3c. As the aerosol can 3, various configurations can be used as long as the contents are discharged by pushing down the stem 3 c.

  The double aerosol actuator 1 includes a fixing member 10 that fixes the pair of aerosol cans 3 in parallel. The fixing member 10 is also called a fixing platen, and each aerosol can 3 is fixed to the fixing member 10 by means of fitting, undercut or the like at the mounting cup 3b portion and assembled in a state of being arranged in parallel with each other. .

  The fixing member 10 can be variously modified in shape as long as the pair of aerosol cans 3 can be arranged and fixed in parallel. Moreover, you may make it package the part of the container main body 3a of a pair of aerosol cans 3 with a shrink film etc. integrally.

  The dual-type aerosol actuator 1 has a nozzle body 11 for discharging the contents discharged from the stem 3c of each aerosol can 3 to the outside. Each nozzle body 11 is formed in a cylindrical shape, and has a pair of stem connection portions 12 that are fitted to the tip of the stem 3c of the corresponding aerosol can 3 and connected to the stem 3c. Each stem connecting portion 12 is connected to a connecting body 13 having a flow path therein, and the connecting body 13 is provided with a nozzle portion 14 formed in a cylindrical shape having an elliptical cross section. The stem 3 c of each aerosol can 3 communicates with the nozzle portion 14 via the stem connection portion 12 and the flow path of the coupling body 13.

  On both the left and right sides of the upper surface of the connecting portion 13 of the nozzle body 11 with the nozzle portion 14 interposed therebetween, a pressing contact wall 15 is integrally provided, and a pressing force is applied to the upper surface of these contact walls 15. By adding, the nozzle body 11 can be pushed down (direction in which the stem is pushed into the container body). And by pushing down the nozzle body 11 downward, the stem 3c of each aerosol can 3 can be pushed down simultaneously, and the contents can be discharged from each stem 3c. The contents discharged from each stem 3 c merge at the nozzle portion 14 through the flow path of the connecting body 13 and are discharged to the outside from the tip of the nozzle portion 14. Thus, by pushing down the nozzle body 11, the two types of content liquids stored in the two aerosol cans 3 can be simultaneously discharged from the nozzle portion 14 to the outside.

  In the illustrated case, the nozzle portion 14 is formed separately from the coupling body 13 and is configured to be fitted and fixed to the coupling body 13. However, the nozzle portion 14 is formed integrally with the coupling body 13. It can also be configured. Further, the cross-sectional shape of the nozzle portion 14 is not limited to an elliptical shape, and may be another cross-sectional shape such as a circular shape or a track elliptical shape.

  A cover body 16 is attached to the pair of aerosol cans 3 so as to be positioned outside the fixing member 10 and the nozzle body 11. The cover body 16 is disposed on the front side of the pair of aerosol cans 3 and the fixing member 10, and on the front side of the nozzle body 11 (in the direction in which the nozzle portion 14 protrudes from the coupling body 13). A front wall portion 18 that covers the front side of the nozzle body 11 and a pair of side wall portions 19 that are arranged on both sides of the nozzle body 11 and cover the side of the nozzle body 11 are provided. The front wall portion 18 is provided with a through hole 18a, and the nozzle portion 14 protrudes forward toward the outside of the front wall portion 18 through the through hole 18a.

  As shown in FIG. 1 and FIG. 2, guide grooves 20 extending in the vertical direction are provided on the inner surfaces of the pair of side wall portions 19, and a guide wall 21 connected to the contact wall 15 provided in the nozzle body 11 is a guide groove. 20 is engaged. When the nozzle body 11 is pushed down, the guide wall 21 moves relative to the guide groove 20 so that the nozzle body 11 can be pushed down straight without being tilted with respect to the stem 3c.

  An operation piece (operation lever) 23 is swingably connected to the front wall portion 18 of the cover body 16 via a hinge portion 22. The operation piece 23 is formed in a plate shape having a constant thickness that curves slightly upward and laterally, and has a plate-like portion 24 connected to the front wall portion 18 via the hinge portion 22 at one end. Yes. A reinforcing flange 25 extending downward is integrally provided at the periphery of the plate-like portion 24. Further, the plate-like portion 24 is disposed above the nozzle body 11, and the lower surface of the flange 25 faces the contact wall 15 of the nozzle body 11 with a predetermined interval.

  Therefore, by pushing down the operation piece 23 downward, the flange 25 can be brought into contact with the contact wall 15 and the nozzle body 11 can be pushed down downward. That is, by pushing down the operation piece 23 downward, the stem 3c of each aerosol can 3 can be pushed toward the container body 3a, and the contents can be discharged from the nozzle portion 14.

  As shown in FIGS. 1 to 3, an overcap 26 that covers the front wall portion 18, the pair of side wall portions 19, and the tip portion of the nozzle portion 14 can be attached to the cover body 16. By attaching the overcap 26 to the cover body 16 during distribution or the like, it is possible to prevent erroneous operation of the operation piece 23 or intrusion of foreign matter into the nozzle portion 14.

  In this double aerosol actuator 1, the rear end of the plate-like portion 24 constituting the operation piece 23, that is, the end opposite to the end connected to the hinge portion 22, is located above the rear end. A protruding wall portion 27 is provided to protrude toward the front. In the case shown in the drawing, the protruding wall portion 27 is formed in a wall shape that extends from one side in the width direction of the plate-like portion 24 to the other side and rises substantially perpendicular to the surface facing the upper side of the plate-like portion 24. ing.

  The protruding height of the protruding wall portion 27 from the surface of the plate-like portion 24 is, for example, the upper end of the protruding wall portion 27 (the upper end opposite to the connecting portion connected to the plate-like portion 24) with the belly of the finger. It is also possible to set it so that the belly of the finger does not contact the surface of the plate-like portion 24 when pressed down.

  Further, the protruding wall portion 27 is such that the upper end thereof is positioned above the connecting portion of the protruding wall portion 27 with the plate-like portion 24 in a state where the operation piece 23 pushes down the pair of stems 3c to the push-off position. It is preferably formed in an angle or shape.

  In the case shown in the figure, the protruding wall portion 27 is formed integrally with the plate-like portion 24. However, a separate structure may be assembled.

  In the dual-type aerosol actuator 1 having such a configuration, in a state where the pair of aerosol cans 3 are mounted, the user pushes the operation piece 23 downward with a finger so that the pair of aerosol cans 3 The stored contents can be discharged from the tip of the nozzle portion 14 to the outside.

  At this time, when the operation piece 23 is pushed down by the finger, the plate-like portion 24 is inclined downward with respect to the push-down direction, and thus the nozzle acts as a pushing force out of the force applied by the finger to the plate-like portion 24. The ratio of the force transmitted to the body 11 decreases, and a large force is required for the operation.

  On the other hand, in the present invention, since the protruding wall portion 27 is provided at the rear end of the plate-like portion 24, by pressing the upper end of the protruding wall portion 27 with a finger and performing a push-down operation, the plate-like portion 24 is It is possible to convert the force directed downward along the axis into a force in a direction in which the stem 3c is pushed down by the projecting wall portion 27, thereby reducing the force required for pushing down the operation piece 23 and making the operation easy. . In particular, when the remaining amount of the contents stored in the aerosol can 3 is reduced and the gas pressure for discharging the contents is also lowered, the plate-like portion 24 is used to push the stem 3c down to the push-off position. Even in this case, the pressing operation can be easily performed with a small force by placing the finger on the protruding wall 27 and performing the pressing operation.

  Further, in a state where the operation piece 23 pushes down the pair of stems 3c to the push-off position, the upper end of the protruding wall portion 27 is positioned above the connection portion with the plate-like portion 24. It is possible to improve the hooking of the finger that pushes down the wall portion 27 to the protruding wall portion 27 and to further facilitate the operation.

  Therefore, by using the dual aerosol actuator 1 of the present invention, the operation of discharging the contents from the dual aerosol container 2 having a pair of stems 3c can be facilitated.

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

  For example, in the above-described embodiment, the double aerosol container 2 is configured to include a pair of aerosol cans 3 each including a stem 3c. It is also possible to use a configuration in which two housing spaces are provided inside the container body 3a, and the mounting cup 3b is provided with a pair of stems 3c corresponding to each housing space.
