In the present embodiment, the guide protrusion 29 is configured as a rib-shaped protrusion that extends downward from the outer edge of the top wall 21.

  As shown in FIG. 1, the nozzle 30 is obtained by integrally connecting a lower member 32 and an upper member 33 through a thin-walled hinge 31. The nozzle 30 is bent along the hinge 31 to be connected to the lower member 32 and the upper member 33. By combining these, the predetermined form shown in FIGS. 1 and 4 is formed.

  As shown in FIG. 1, the lower member 32 includes a cylindrical portion 32b having an inner diameter corresponding to the outer diameter of the stem 2c on the lower surface of a plate-like base portion 32a. An internal wall 32d having a hole 32c is provided.

Further, a claw-like lower engaging portion 32g is provided on the upper surface front side of the base portion 32a as shown in FIG.

  Further, a guide tube portion 32 h that is guided in the vertical direction by the outer peripheral surface of the intermediate annular wall 14 of the stationary platen 10 is integrally provided on the lower surface of the base portion 32 a of the nozzle 30. When the nozzle 30 operates up and down together with the stem 2c, the guide cylinder portion 32h is restricted from moving in directions other than the vertical direction by the outer peripheral surface of the intermediate annular wall 14. As a result, when the nozzle 30 operates up and down during the discharge of the contents, the guide cylinder portion 32h of the nozzle 30 is guided in the vertical direction by the outer peripheral surface of the intermediate annular wall 14, and the operation stability of the nozzle 30 is enhanced. The guide cylinder portion 32h can be configured to be slidable on the outer peripheral surface of the intermediate annular wall 14. Further, since the nozzle 30 is provided with the guide cylinder portion 32h, the nozzle 30 can be easily attached to the stem 2c. That is, when the nozzle 30 is mounted, the guide cylinder portion 32h can be disposed so as to cover the intermediate annular wall 14, and the nozzle 30 can be easily positioned in the horizontal direction.

  As shown in FIG. 4, the lower end of the guide tube portion 32h is provided with a locking leg portion 32i on both the left and right sides. The locking leg portion 32 i is formed with a bent portion 32 j that is disposed inside the elastic piece 27 and bends downward from the direction toward the elastic piece 27. By providing such a locking leg portion 32i on the guide tube portion 32h, the nozzle 30 with respect to the stationary platen 10 is arranged based on the positional relationship between the locking leg portion 32i and the engaging hole 18 of the stationary platen 10. The mounting angle in the rotation direction can be confirmed visually. Accordingly, the provision of the locking leg 32i facilitates the positioning of the nozzle 30 when the nozzle 30 is mounted on the stem 2c. Further, these locking leg portions 32 i are provided with inner protrusions 32 k that are inserted into the engagement holes 18 of the stationary platen 10 and locked to the inner edge portions of the engagement holes 18. Accordingly, by inserting these locking leg portions 32i into the engagement holes 18 and engaging them with the upper flange 15 of the stationary platen 10 by the inner protrusions 32k, the nozzle 30 is prevented from falling off from the stem 2c. Can do.

  As shown in FIG. 1, the upper member 33 includes a box-like portion 33 a that is folded along the hinge 31 so as to accommodate the annular portion 32 e on the inner side and cover the annular portion 32 e. A partition wall 33b that divides the inside of the box-shaped portion 33a into two is provided at the center of the box-shaped portion 33a. Further, on the upper surface side of the box-shaped portion 33a, semicircular ribs 33c that are semicircular when viewed from the side are provided (in this embodiment, two in total in the left-right direction), and the box-shaped portion 33a. Is provided with a cylindrical portion 33e whose opening at the tip is a discharge port 33d to the outside of the contents. In this embodiment, the partition wall 33b is extended to the discharge port 33d side rather than the boundary of the box-shaped part 33a and the cylindrical part 33e. Further, an upper engaging portion 33f having a claw shape corresponding to the lower engaging portion 32g is provided below the cylindrical portion 33e.

  Then, as described above, the lower engagement portion 32g and the upper engagement portion 33f are engaged with each other by bending along the hinge 31, and the two-fold state is maintained. In addition, the annular portion 32e and the box-shaped portion 33a are fitted together to form an internal space inside the base portion 32a and the box-shaped portion 33a, while the partition wall 33b is formed between the paired intermediate walls 32f. The internal space is partitioned into two spaces each connected to the through hole 32c. Furthermore, these two spaces merge inside the cylindrical portion 33e on the discharge port 33d side beyond the partition wall 33b. That is, a passage R that is divided into two on the pair of cylindrical portions 32b side (stem 2c side) and merges into one on the discharge port 33d side is formed inside the nozzle 30 that is folded in two, The passage R connects the inside of the pair of cylindrical portions 32b and the discharge port 33d.

  In attaching each member configured as described above to the container 2, the fixed platen 10 is first attached to the mounting cup 2b. As described above, the thin tongue piece 13a is provided on the front side and the back side of the inner annular wall 13, and extends downward along the inner annular wall 13 before the fixing plate 10 is attached to the mounting cup 2b. Is. Here, the upper projection 2d of the mounting cup 2b and the inner annular wall 13 of the fixed plate 10 fitted to the upper cup 2b have a track shape in plan view, so that the fixed plate 10 is moved from above the mounting cup 2b. When approaching each other, when the directions of each other are in alignment, the fixed platen 10 is lowered to a height at which the lower end of the thin tongue 13a abuts against the upper surface of the middle projection 2e. In other words, the tip of the thin tongue 13a is in contact with the upper surface of the upper projection 2d and is positioned higher than a predetermined height. That is, since it is possible to determine whether or not the directions of both are in accordance with the difference in height of the fixed platen 10, the assembling work becomes easier. Further, when the fixed platen 10 is rotated, the fixed platen 10 moves downward when both directions are matched, so that it is possible to know the completion of the alignment with a tactile sense. Thereafter, when the stationary platen 10 is pushed in, the thin tongue 13a is bent outward as shown in FIG. 1, the convex portion 15b engages with the lower concave portion 2h, and the stationary platen 10 is fixed to the mounting cup 2b.

  Next, the nozzle 30 assembled in a folded state is attached from above while aligning the cylindrical portion 32b with the stem 2c. At this time, while visually confirming the locking leg portion 32 i provided in the nozzle 30 and the engagement hole 18 provided in the stationary platen 10, the nozzle 30 is checked with respect to the rotational angle of the nozzle 30 with respect to the stationary platen 10 while checking the mounting angle. The guide tube portion 32 h provided at 30 is disposed and positioned so as to cover the intermediate annular wall 14 of the stationary platen 10. Since the inner wall 32d is provided inside the cylindrical portion 32b, the upper end of the stem 2c comes into contact with the lower surface of the inner wall 32d by pressing the stem 2c so as not to be pushed in, and the nozzle 30 has a predetermined height. Installed.

  Thereafter, the cover member 20 is pressed from above, the cylindrical portion 33e of the nozzle 30 is projected from the window hole 25b, and the claw portion T is pressed in a state aligned with the engagement hole 18 to be mounted on the fixed platen 10. . Here, since the outer protrusion 28 of the claw portion T is provided with the inclined surface 28a, when the cover member 20 is pressed against the stationary platen 10, the inclined surface 28a of the outer protrusion 28 of the claw portion T is formed on the lower flange 16b. By being in contact with the inner peripheral surface, it is guided radially inward and inserted into the engagement hole 18 while being bent. The cover member 20 is detachably attached to the stationary platen 10 by engaging the outer protrusion 28 of the claw T with the lower surface of the lower flange 16b. At this time, the guide protrusion 29 provided on the inner wall surface of the elastic piece 27 of the claw T is supported by the locking leg portion 32i provided on the nozzle 30, thereby suppressing the retraction of the elastic piece 27 to the inside, Since the outer protrusion 28 of the elastic piece 27 can be inserted into the engagement hole 18 of the fixed platen 10, an appropriate undercut feeling (feeling or sound) can be provided.

  After the mounting of the cover member 20 is completed, the lower end of the cover member 20 and a part of the lower surface of the lower flange 27a of the elastic piece 27 come into contact with the upper surface of the lower flange 16b of the stationary platen 10. As a result, the cover member 20 is stably held on the stationary platen 10, and wobble or the like during use is suppressed. When the cover member 20 is attached to the stationary platen 10, the nozzle 30 attached to the stem 2 c of the aerosol container 2 is covered with the cover member 20.

  In order to discharge the contents from the aerosol container 2 to which each member is attached in this manner, the finger is placed on the upper surface of the operation unit 23 and pushed downward. Here, since the upper surface of the operation unit 23 is curved downward, a good finger contact can be exhibited. Moreover, the rib 23a can suppress the displacement of the finger during pressing. Then, when the operation unit 23 swings around the hinge 24, the lower surface of the operation unit 23 comes into contact with the semicircular rib 33c and pushes down the two stems 2c together with the nozzle 30. As a result, the two types of contents in the container 2 are simultaneously ejected from the respective stems 2 c and discharged from the discharge port 33 d through the passage R formed inside the nozzle 30.

  At this time, when the nozzle 30 is pushed down by the operation of the operation unit 23, the guide tube portion 32h is guided in the vertical direction by the outer peripheral surface of the intermediate annular wall 14 of the fixed platen 10, so that the content can be discharged at the time of discharging the contents. The operational stability of the nozzle 30 can be enhanced.

  A vertical rib extending vertically is provided on either the inner surface of the guide tube 32h of the nozzle 30 or the outer surface of the intermediate annular wall 14 of the fixed platen 10, and this vertical rib is used as the inner surface of the guide tube 32h of the nozzle 30 or the fixed platen. A structure in which the forward inclination of the nozzle 30 is suppressed by engaging with a longitudinal groove provided on either one of the outer surfaces of the intermediate annular wall 10 to further increase the operational stability of the nozzle 30 when discharging contents. You can also Also, such vertical ribs and vertical grooves can be provided between the outer surface of the guide tube 32 h of the nozzle 30 and the outer peripheral wall 25 of the cover member 20.

  The cover member 20 is disengaged from the engagement hole 18 by pressing the claw portion T inward in the radial direction, and can be removed from the fixed platen 10. At that time, the elastic piece 27 of the claw T of the cover member 20 is pressed inward in the radial direction to bend the elastic piece 27, and the outer protrusion 28 provided at the tip thereof and the engagement hole of the fixed platen 10. 18, the cover member 20 is lifted as the elastic piece 27 is pressed inward through the contact between the guide protrusion 29 of the elastic piece 27 and the locking leg 32 i of the nozzle 30. Therefore, removal of the cover member 20 can be induced. In the present embodiment, since the two claw portions T are provided so as to face each other with the central axis M of the container 2 interposed therebetween, the claw portions T are pressed so as to be sandwiched between the thumb and other fingers. The cover member 20 can be easily removed with one hand.

  Further, in the present embodiment, the locking leg portion 32i includes a bent portion 32j that bends downward from the direction toward the elastic piece 27, and the guide protrusion 29 is inclined outwardly downward and has a bent portion 32j. Since the contacted inclined surface 29a is provided, the cover member 20 can be smoothly raised through the contact with the inner pressing of the elastic piece 27. In this embodiment, the guide protrusion 29 and the locking leg 32i are in contact with each other at the time of locking the claw T to the engaging hole 18 as shown in FIG. 29 and the locking leg 32i, when the claw T is locked in the engagement hole 18, the guide projection 29 pushes the locking leg 32i downward and pushes down the stem 2c to discharge the contents. It is preferable to configure so that there is no. Moreover, it may replace with such a structure and you may comprise so that the guide protrusion 29 and the latching leg part 32i may contact with the press to the inner side of the elastic piece 27. FIG.

  In this embodiment, since the locking leg 32i is connected to the lower end of the guide cylinder 32h, the guide protrusion 29 is formed on the locking leg 32i when the cover member 20 is attached and removed. When pressed, the latching leg 32i is supported by the guide cylinder 32h and the intermediate annular wall 14 of the stationary platen 10 abutting against the guide cylinder 32h, and the latching leg 32i is radially inward. Evacuation can be suppressed. Accordingly, it is possible to further enhance the effect of improving the feeling of getting over the undercut when the cover member 20 is attached and the effect of pushing up the cover member 20 when the cover member 20 is removed.

  Further, in this embodiment, the locking leg 32 i is provided with an inner protrusion 32 k that is inserted into the engagement hole 18 of the fixed platen 10 and locked to the inner edge of the engagement hole 18. When the guide protrusion 29 is pressed against the locking leg 32 i when the cover member 20 is attached and removed, the locking leg 32 i is supported by the inner edge of the engagement hole 18. Retraction of the locking leg 32i to the inside in the radial direction can be suppressed. Therefore, it is possible to further enhance the effect of improving the feeling of getting over the undercut when the cover member 20 is attached and the effect of pushing up the cover member 20 when the cover member 20 is removed.

  Since the nozzle 30 is formed separately from the cover member 20 and can be separated from the cover member 20, the nozzle 30 is mounted on the stem 2c even when the cover member 20 is removed from the stationary platen 10. It remains on the container 2 side and is exposed to the outside. And if the nozzle 30 exposed outside is pulled upwards, the nozzle 30 can be easily removed from the stem 2c. Thereafter, by opening the lower member 32 and the upper member 33 of the nozzle 30 so as to be separated from each other, the inside thereof is exposed, so that the contents remaining in the nozzle 30 can be easily washed. After cleaning the nozzle 30, the nozzle 30 and the cover member 20 may be remounted according to the above-described procedure.
