  As shown in FIGS. 2A to 2C, the nozzle body 3 includes an upper member 3 a provided with the discharge cylinder 31 and a lower side provided with a pair of stem connection portions 32 connected to the stem 25. The member 3b is integrally connected via a hinge 33 formed in a thin shape. The discharge cylinder 31 is formed with two channels through which the contents from each stem 25 pass. The nozzle body 3 is molded by injection molding or the like in the unfolded state as shown in FIGS. 2A and 2B, and is bent along the hinge portion 33 so that the upper member 3a and the lower member 3b are fitted. The use state shown in FIG. In addition, in the cross-sectional view of the nozzle body 3 shown in FIG. 1 and the like, the upper member 3a is one of the two content channels provided in the discharge cylinder 31 so that the content channel can be easily understood. A cut surface passing through the central axis is shown, and the lower member 3b shows a cut surface passing through the central axis of one of the two stem connecting portions 32.

  1 and FIG. 2 (c), the nozzle body 3 has two contents of the contents for communicating each stem connecting portion 32 and the discharge cylinder 31 between the upper member 3a and the lower member 3b. The flow path is partitioned. As a result, the stem 25 of the aerosol container 2 communicates with the discharge cylinder 31 via the stem connecting portion 32 and the flow path in the nozzle body 3.

  The pair of stem connection portions 32 provided on the lower member 3 b are each formed in a cylindrical shape and are fitted to the stem 25. Further, a front rib 34 and a rear rib 35 are provided on both the left and right sides of the lower member 3b. The front rib 34 and the rear rib 35 constitute a pair of front and rear guide protrusions in the present invention. In this example, the rib width w1 of the front rib 34 is larger than the rib width w2 of the rear rib 35.

  The front rib 34 is provided at the tip of a pair of front elastic pieces 36 that extend from the front edge of the lower member 3b to the left and right sides. Since the front elastic piece 36 is configured to be elastically deformable toward the gap 37 provided on the inner side, the front rib 34 can be displaced inward in the left-right direction along with the elastic deformation of the front elastic piece 36. Yes. The rear ribs 35 are provided at the tip portions of a pair of rear elastic pieces 38 extending from the rear portion of the lower member 3b to the left and right sides. Since the rear elastic piece 38 is configured to be elastically deformable toward the gap 39 provided on the inner side, the rear rib 35 can be displaced inward in the left-right direction as the rear elastic piece 38 is elastically deformed. ing.

  In the state where the nozzle body 3 shown in FIG. 2C is used, when the side where the tip 31 a of the discharge cylinder 31 is located is the front side of the nozzle body 3, the front rib 34 is more forward than the pair of stem connection portions 32. The rear rib 35 is disposed behind the pair of stem connecting portions 32. In this way, by arranging the front rib 34 and the rear rib 35 at positions shifted forward and backward from the stem connection portion 32, the left and right direction of the nozzle body 3 can be compared with the case where a protrusion is provided directly beside the stem connection portion 32. The width w3 can be reduced.

  The left and right rear elastic pieces 38 are respectively provided with support pieces 40 extending horizontally toward the rear side. The upper member 3a of the nozzle body 3 is provided with a pair of pressing-down contact walls 41 protruding upward.

  As shown in FIG. 1, the cover body 4 of the present embodiment is composed of a stationary platen 5 attached to the mounting cup 22 of the aerosol container 2 and a cover member 6 detachably attached to the stationary platen 5. Yes.

  As shown in FIGS. 3A and 3B, the stationary platen 5 includes an upper wall 51 having an opening 51 a at the center and a substantially cylindrical side wall 52 that surrounds the side surface of the mounting cup body 24. ing. The side wall 52 of the present embodiment has a flat portion 52 a at a position corresponding to a planar portion on the side surface of the mounting cup main body 24, so that it does not rotate with respect to the mounting cup main body 24. Further, a flange 53 extending radially outward is provided at the lower part of the side wall 52, and the lower part of the flange 53 surrounds the annular part 23 and is fitted and held in the annular part 23. A wall 54 is provided. A cylindrical outer wall 55 extending downward is provided on the outer edge of the flange 53.

  On the outer surface of the side wall 52, a mark convex portion 56 is provided as a mark when the cover member 6 is attached to the fixed platen 5. The said mark convex part 56 is each provided in the position corresponding to the said flat part 52a, and the position which shifted | deviated 180 degree | times from the flat part 52a in the circumferential direction. In addition, slits 57 are formed in the outer wall 55 at positions corresponding to the pair of mark protrusions 56, and engagement protrusions 58 are provided at two positions shifted from the slit 57 by 90 degrees in the circumferential direction. It has been.

  As shown in FIG. 4, the cover member 6 includes a cylindrical peripheral wall 61 that surrounds the upper end of the aerosol container 2, the stationary platen 5, and the nozzle body 3, a top wall 62 that continues to the top of the peripheral wall 61, and a top wall 62. And a guide wall 63 that hangs down. On the inner surface of the peripheral wall 61, positioning ribs 61 a that are fitted into a pair of slits 57 formed in the stationary platen 5 are provided. Note that the cover member 6 of the present embodiment is configured to be able to be mounted on the stationary platen 5 even when rotated 180 degrees from the state shown in FIG.

  A front opening 64 for projecting the tip 31a of the discharge cylinder 31 forward is formed on the front side of the peripheral wall 61. A mark convex portion 56 is fitted below the front opening 64 to confirm the mounting. A mark opening 61b is formed. A rear opening 65 is formed on the rear side of the peripheral wall 61, and side openings 61 c that engage with the engaging protrusions 58 of the stationary platen 5 are formed on the left and right sides of the peripheral wall 61. The side opening 61c is formed in an elastic portion 61e formed so as to be elastically deformable by the groove 61d. In addition, above the front opening 64, an operation piece 67 is provided between the pair of guide walls 63 so as to be swingable with respect to the top wall 62 via a thin hinge 66. When discharging the contents, the operation piece 67 is pushed down from above so that the lower surface of the operation piece 67 comes into contact with the contact wall 41 and the nozzle body 3 is pushed down.

  The guide walls 63 are located on the left and right sides with the nozzle body 3 in between, and a pair of front and rear guide grooves 68 into which the front ribs 34 and the rear ribs 35 are slidably fitted in the respective guide walls 63, 69 is formed. The guide groove 68 on the front side and the guide groove 69 on the rear side are formed in a notch shape from the lower end of the guide wall 63 and extend in the vertical direction (direction parallel to the central axis C of the container) parallel to the pushing-down direction of the stem 25. ing. The groove width w4 of the guide groove 68 on the front side is larger than the groove width w5 of the guide groove 69 on the rear side.

  Here, when the discharge device 1 having the above-described configuration is set in the aerosol container 2, the nozzle body 3 temporarily set on the cover member 6 is mounted on the stationary platen 5 mounted on the aerosol container 2. In the present embodiment, when the nozzle body 3 is temporarily set on the cover member 6, the nozzle body 3 is inserted from the rear opening 65 of the cover member 6 as shown in FIG. When the nozzle body 3 is temporarily set on the cover member 6, if the nozzle body 3 is inserted from below the cover member 6 and temporarily set, the insertion becomes difficult if the discharge cylinder 31 is too long. However, in the present embodiment, the nozzle body 3 is inserted from the rear opening 65, so that it can be easily set regardless of the length of the discharge cylinder 31.

  In the present embodiment, the width w3 (see FIG. 2A) of the nozzle body 3 in the left-right direction is larger than the width w6 of the rear opening 65, that is, the distance between the left and right guide walls 63 (see FIG. 6). It is said. Therefore, when the nozzle body 3 is inserted, the front ribs 34 and the rear ribs 35 abut against the guide walls 63 on both sides, but the front ribs 34 and the rear ribs 35 are inward due to elastic deformation of the front elastic pieces 36 and the rear elastic pieces 38. Therefore, the nozzle body 3 can be easily inserted. When the nozzle body 3 is inserted and the front rib 34 and the rear rib 35 are fitted into the front and rear guide grooves 68 and 69, the movement in the front-rear direction is stopped, and the temporary setting is completed.

  Since the rib width w1 of the front rib 34 is larger than the groove width w5 of the guide groove 69 on the rear side, the front rib 34 does not fit into the rear rib 35 during the insertion process of the nozzle body 3. Therefore, the insertion of the nozzle body 3 can be performed smoothly without stopping on the way. In the present embodiment, when the nozzle body 3 is inserted, the contact wall 41 is in contact with the lower surface of the operation piece 67 and the operation piece 67 is automatically displaced upward. Is even easier.

  As shown in FIG. 5B, in the present embodiment, the lower surface of the discharge cylinder 31 is in contact with the front support portion 64 a provided at the lower end of the opening edge of the front opening 64 with the nozzle body 3 temporarily set on the cover member 6. Supported in contact. In addition, the pair of support pieces 40 of the nozzle body 3 are configured to be in contact with and supported by a pair of rear support portions 65 a provided at the lower end of the opening edge of the rear opening 65. Thereby, since the nozzle body 3 can be prevented from falling off from the cover member 6 in the temporary setting state, the setting on the aerosol container 2 is facilitated. Further, with the nozzle body 3 temporarily set on the cover member 6, the displacement of the nozzle body 3 in the left-right direction is restricted by the guide walls 63 on both sides, and the displacement in the front-rear direction is fitted in the front and rear guide grooves 68 and 69, respectively. Since it is regulated by the front rib 34 and the rear rib 35, the position is stabilized. Thereby, the stem connection part 32 of the nozzle body 3 can be easily fitted to the stem 25 only by attaching the cover member 6 to the fixed platen 5. When the cover member 6 is attached to the fixed platen 5, the alignment can be easily performed by aligning the direction of the mark convex portion 56 of the fixed platen 5 with the mark opening 61b of the cover member 6. When the circumferential direction position of the cover member 6 with respect to the stationary platen 5 is not correct, the lower end of the positioning rib 61a contacts the upper end of the outer wall 55 as shown in FIG. It is preventing.

  As shown in FIG. 1, when the contents are discharged from the aerosol container 2 equipped with the discharge tool 1, the operation piece 67 is pushed down as shown in FIG. The nozzle body 3 pressed by the operation piece 67 moves straight in the direction in which the stem 25 is pushed down by the front rib 34 and the rear rib 35 slidably fitted in the front and rear guide grooves 68 and 69. As a result, the force in the downward direction can be transmitted straight to each stem 25, and the balance of the contents discharged from each stem 25 can be stabilized. The operational stability of the nozzle body 3 is improved, and the two stems 25 are both pushed straight down in the push-down direction, so that the contents can be discharged from each stem 25 with an appropriate discharge amount balance.

  In the present embodiment, the width w3 of the rear opening 65 is reduced by disposing the front rib 34 and the rear rib 35 at positions shifted forward and backward from the stem connection portion 32, thereby reducing the width w3 of the rear opening 65. That is, the distance between the pair of guide walls 63 can be kept small. By narrowing the distance between the pair of guide walls 63, the position where the finger is placed when the operation piece 67 is pushed down can be guided to the center in the left-right direction. As a result, the two stems 25 are easily pushed down evenly, and the balance of the discharge amounts is further stabilized.

  Although the present invention has been described based on the illustrated examples, the present invention is not limited to the above-described embodiment, and can be appropriately changed within the scope of the claims. For example, the previous embodiment Then, although it was set as the structure inserted and inserted temporarily from the back opening 65 of the cover member 6, it is good also as a structure inserted from the front opening 64. FIG. In this case, the rib width w2 of the rear rib 35 is made larger than the rib width w1 of the front rib 34 and the groove width w4 of the front guide groove 68, and the rear rib 35 is inserted into the front guide groove 68 at the time of insertion. It is preferable to set it as the structure which does not fit in. In addition, the present invention separately accommodates two types of contents in one container and is not limited to an aerosol container having two stems. The present invention can also be applied to a single type aerosol container having a stem and a double type aerosol container in which a single type container is arranged side by side.
