  As shown in FIG. 5, 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 3 is formed.

  As shown in FIG. 5, 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 the plate-like base portion 32a. An internal wall 32d having a hole 32c is provided. As is apparent with reference to FIG. 3, a total of two sets including the cylindrical portion 32b, the through hole 32c, and the inner wall 32d are provided corresponding to the container 2 having the two stems 2c. An annular part 32e is provided on the upper surface of the base part 32a, and the annular part 32e has a longer distance between the left and right than the distance from the front side toward the back side. In addition, as shown in FIG. 3, a pair of intermediate walls 32f provided at intervals are provided at the center of the annular portion 32e. 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 having a shape corresponding to the outer shape 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. The guide cylinder portion 32h is fitted on the outer side of the intermediate annular wall 14 of the stationary platen 10, and when the nozzle 30 is moved up and down together with the stem 2c, the inner peripheral surface thereof is in sliding contact with the outer peripheral surface of the intermediate annular wall 14. That is, the guide cylinder portion 32 h is fitted to the outside of the intermediate annular wall 14 of the fixed platen 10 so as to be slidable in the vertical direction. Thus, when the nozzle 30 is operated up and down during the discharge of the contents, the guide cylinder portion 32h of the nozzle 30 is guided by sliding contact with the intermediate annular wall 14, and the operation stability of the nozzle 30 is enhanced.

  As shown in FIG. 3, locking leg portions 32i are provided on the left and right sides of the guide tube portion 32h. By providing the guide leg 32i with the locking leg 32i, the rotation direction of the nozzle 30 relative to the stationary platen 10 is determined based on the positional relationship between the locking leg 32i and the engagement hole 18 of the stationary platen 10. The mounting angle 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 32i are inserted into the engagement holes 18 provided in the fixed platen 10 and engaged with the upper flange 15 of the fixed platen 10 undercut, so that the nozzle 30 is removed from the stem 2c. Can be prevented. In the present embodiment, positioning locking legs 32i are provided on both the left and right sides of the guide cylinder part 32h. However, the locking legs 32i are provided on either the left or right side of the guide cylinder part 32h. It is also possible to provide a structure in which only the locking leg 32i is engaged with the upper flange 15 undercut.

  The upper member 33 is provided with a box-shaped portion 33a that is folded along the hinge 31 so as to accommodate the annular portion 32e on the inner side and cover the annular portion 32e. 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 (the upper surface side when the nozzle 30 is assembled as shown in FIG. 1), a semicircular rib 33c that is semicircular in a side view is provided (this embodiment). Then, a total of two spaced apart in the left-right direction), and on the front side of the box-shaped portion 33a (front side when the nozzle 30 is assembled), the tip opening is used as the discharge port 33d to the outside of the contents. A cylindrical portion 33e is provided. 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 (lower side when the nozzle 30 is assembled).

  And as above-mentioned, by folding along the hinge 31, the lower engaging part 32g and the upper engaging part 33f can engage, and a half-folded state can be 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, inside the nozzle 30 that is folded in two, there 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 upstream side (discharge port 33d). 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 inserted from above while the cylindrical portion 32b is aligned with the stem 2c. At this time, the nozzle 30 is positioned with respect to the stationary platen 10 by visually observing the locking leg portion 32 i provided in the nozzle 30 and the engagement hole 18 provided in 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.

  Since the mounting cup 2b and the stem 2c of the container 2 are arranged symmetrically with respect to the central axis M of the container 2, the nozzle 30 is disposed in the container with respect to the posture shown in FIGS. The container 2 can be mounted even in a posture reversed 180 degrees with respect to the center axis M of 2.

  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 projection 28 of the claw portion T is provided with the inclined surface 28a, when the cover member 20 is pressed against the fixed plate 10, the claw portion T has the inclined surface 28a abutted against the inner peripheral surface of the lower flange 16b. By being brought into contact, 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 the protrusion 28 of the claw T engaging with the lower surface of the lower flange 16b.

  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 connecting flange 29 abut on 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 portion 23, the guide tube portion 32h slides with respect to the intermediate annular wall 14 of the stationary platen 10, that is, the guide tube portion 32h is guided to the intermediate annular wall 14. As a result, the operational stability of the nozzle 30 when discharging the contents 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. In the present embodiment, the two claw portions T are provided so as to face each other with the central axis M of the container 2 interposed therebetween. Therefore, by pressing these claw portions T so as to be sandwiched between the thumb and other fingers, Thus, the cover member 20 can be easily 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 can be removed even if the cover member 20 is removed from the stationary platen 10 as shown in FIG. 6. Remains on the side of the container 2 while being mounted on the stem 2c, 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.

  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 present embodiment, the convex portion 15b of the fixed platen 10 is engaged with the lower concave portion 2h of the mounting cup 2b, but may be engaged with the middle concave portion 2g.

  Further, in this embodiment, the guide tube portion 32h provided in the nozzle 30 is slidably fitted in the vertical direction outside the intermediate annular wall 14 provided in the stationary platen 10, but for example, the outer annular wall 16a, etc. The guide tube portion 32h of the nozzle 30 may be slidably fitted in the up and down direction on the outer side of another annular wall provided on the fixed platen 10.

  Further, the partition wall 33b of the present embodiment divides the inside of the box-shaped portion 33a into two and extends beyond the base of the cylindrical portion 33e. However, depending on the type of contents, the discharge port 33d The entire area of the passage R may be divided into two, or the partition wall 33b may be removed to make the entire interior of the nozzle 30 into one passage.

  Furthermore, although the shoulder cover 1 of this embodiment was comprised so that it might mount | wear with the container 2 which has the two stems 2c, it can also be employ | adopted as a single type container or a double type container.
