Further, in the present embodiment, the locking leg portion 32i is provided with a bent portion 32j that bends downward from the direction toward the elastic piece 27, and the guide projection 29 is inclined outward toward the lower side, as will be described later. At the same time, it is provided with an inclined surface 29a that comes into contact with the bent portion 32j. In the present embodiment, the guide protrusion 29 is configured as a rib-shaped protrusion extending downward from the outer edge of the top wall 21.

As shown in FIG. 1, the nozzle 30 has a lower member 32 and an upper member 33 integrally connected via a thin-walled hinge 31, and is bent along the hinge 31 to form a lower member 32 and an upper member 33. By combining the above, the predetermined forms shown in FIGS. 1 to 4 are 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 the plate-shaped base portion 32a, and penetrates inside the cylindrical portion 32b. It includes an internal wall 32d with a hole 32c. A total of two sets of 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 portion 32e is provided on the upper surface of the base portion 32a. Further, as shown in FIG. 2, a pair of intermediate walls 32f provided at intervals are provided in the central portion of the annular portion 32e. Further, as shown in FIG. 1, a claw-shaped lower engaging portion 32g is provided on the front surface side of the upper surface of the base portion 32a.

Further, on the lower surface of the base portion 32a of the nozzle 30, a guide cylinder portion 32h that is guided in the vertical direction by the outer peripheral surface of the intermediate annular wall 14 of the fixing plate 10 is integrally provided. When the nozzle 30 operates up and down together with the stem 2c, the guide cylinder portion 32h is restricted from moving in a direction other than the up and down direction by the outer peripheral surface of the intermediate annular wall 14. As a result, when the nozzle 30 operates up and down when the contents are discharged, 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 improved. The guide cylinder portion 32h can also be slidably configured on the outer peripheral surface of the intermediate annular wall 14. Further, since the guide cylinder portion 32h is provided on the nozzle 30, the nozzle 30 can be easily attached to the stem 2c. That is, when mounting the nozzle 30, the guide cylinder portion 32h can be arranged 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. 2, at the lower end of the guide cylinder portion 32h, locking leg portions 32i are continuously provided on both the left and right sides thereof. The locking leg portion 32i is formed with a bent portion 32j that is arranged inside the elastic piece 27 and bends downward from the direction toward the elastic piece 27. Further, these locking legs 32i are provided with inner protrusions 32k that are inserted into the engaging holes 18 of the fixing plate 10 and locked to the inner edges of the engaging holes 18. By inserting these locking legs 32i into the engaging holes 18 and undercutting them with the upper flange 15 of the fixing plate 10 by the inner protrusion 32k, it is possible to prevent the nozzle 30 from falling off from the stem 2c. ..

As shown in FIG. 1, the upper member 33 includes a box-shaped portion 33a that accommodates the annular portion 32e inside and covers the annular portion 32e by bending along the hinge 31. At the center of the box-shaped portion 33a, a partition wall 33b that divides the inside of the box-shaped portion 33a into two is provided. Further, on the upper surface side of the box-shaped portion 33a, a semicircular rib 33c that is semicircular when viewed from the side is provided. In the present embodiment, a total of two semicircular ribs 33c are provided at intervals in the left-right direction. On the front side of the box-shaped portion 33a, a discharge cylinder 33e is provided whose tip opening is a discharge port 33d to the outside world of the contents. On the lower side of the discharge cylinder 33e, an upper engaging portion 33f having a claw shape corresponding to the lower engaging portion 32g is provided.

By fitting the annular portion 32e and the box-shaped portion 33a, an internal space is formed inside the base portion 32a and the box-shaped portion 33a, while the partition wall 33b is sandwiched between the paired intermediate walls 32f. The internal space is divided into two spaces, each of which is connected to a through hole 32c. Further, these two spaces meet inside the discharge cylinder 33e on the discharge port 33d side beyond the partition wall 33b. That is, inside the nozzle 30 folded in half, a passage R is formed, which is divided into two on the pair of cylindrical portions 32b side (stem 2c side) and merges on the discharge port 33d side to become one. The inside of the pair of cylindrical portions 32b and the discharge port 33d are connected by this passage R.

When attaching each member configured as described above to the container 2, the fixing plate 10 is first attached to the mounting cup 2b. Next, the nozzle 30 assembled in the folded state is attached from above while aligning the cylindrical portion 32b with the stem 2c. The cover member 20 is mounted on the fixing plate 10 by pressing the claw portion T in a state of being aligned with the engaging hole 18 while projecting the discharge cylinder 33e of the nozzle 30 from above from the front opening 25b. The cover member 20 is detachably attached to the fixing plate 10 by engaging the outer protrusion 28 of the claw portion T with the lower surface of the lower flange 16b. When the cover member 20 is attached to the fixing plate 10, the nozzle 30 attached to the stem 2c 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 way, a finger is placed on the upper surface of the operation unit 23 and the contents are pushed downward. Then, when the operation unit 23 swings with the hinge 24 as the starting point, the lower surface of the operation unit 23 presses against 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 2c, and are ejected from the discharge port 33d through the passage R formed inside the nozzle 30.

The cover member 20 can be removed from the fixing plate 10 by pressing the claw portion T inward in the radial direction to release the engagement with the engaging hole 18. 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 attached to the stem 2c even if the cover member 20 is removed from the fixing plate 10. It remains on the side of the container 2 and is exposed to the outside. Then, if the nozzle 30 exposed to the outside is pulled upward, the nozzle 30 can be easily removed from the stem 2c. After that, the lower member 32 and the upper member 33 of the nozzle 30 are opened so as to be separated from each other to expose the inside thereof, so that the contents remaining inside the nozzle 30 can be easily washed.

As described above, in the discharge tool 1 of the present embodiment, the discharge cylinder 33e is provided by providing the guard portion 26 that covers the discharge cylinder 33e of the nozzle 30 protruding from the front opening 25b of the cover member 20 from above. On the other hand, it becomes difficult for an external object or the like to come into contact with the object from above. As a result, it is possible to prevent the nozzle 30 from being unintentionally pushed down and the contents from being illegally discharged, for example, during distribution. In addition, it is possible to suppress unauthorized deformation of the discharge cylinder 33e due to contact with an external object or the like. Further, since the overcap is not required, there is an advantage that the number of parts does not increase and it is not necessary to attach / detach the overcap each time it is used.

In the discharge tool 1 of the present embodiment, the tip of the discharge cylinder 33e is preferably located in front of the tip 26a (front end) of the guard portion 26, and according to this, the contents. Since the discharge port 33d can be visually recognized when discharging, it becomes easy to confirm the discharge position and the discharge amount.

The guard portion 26 is preferably sized so as to cover at least half the length and width of the portion of the discharge cylinder 33e protruding forward from the front opening 25b in the plan view shown in FIG. According to this, the effect of suppressing the illegal outflow of the contents can be more reliably exerted. From this point of view, more preferably, the guard portion 26 has a size capable of covering two-thirds or more of the length and width of the portion of the discharge cylinder 33e protruding forward from the front opening 25b in a plan view. It is preferable to do so.

4 (a) and 4 (b) show an aerosol container discharge tool 100 according to another embodiment of the present invention. In the present embodiment, the guard portion 126 is provided so as to cover the upper side and the side surface of the discharge cylinder 33e. That is, the guard portion 126 has an upper wall 126b located above the discharge cylinder 33e and side walls 126c connected to the upper wall 126b and located on both sides of the discharge cylinder 33e. Also in this embodiment, the tip of the discharge cylinder 33e is located in front of the tip 126a of the guard portion 126.

As described above, since the guard portion 126 is provided so as to cover the upper side and the side surface of the discharge cylinder 33e, it is possible to prevent the contact of an external object not only from the upper side but also from the side surface. Therefore, it is possible to enhance the effect of suppressing the illegal deformation of the discharge cylinder 33e and the illegal outflow of the contents. Further, since the lateral wall 126c protruding from the front wall 25a is connected so as to be orthogonal to the upper wall 126b, the strength of the guard portion 126 itself is higher than that in the case of only the upper wall 126b. As a result, the guard portion 126 is less likely to be deformed, so that the effect of suppressing the illegal deformation of the discharge cylinder 33e and the effect of suppressing the illegal outflow of the contents can be enhanced.

It goes without saying that the present invention is not limited to the above-described embodiment and can be variously modified without departing from the gist thereof.

For example, in the present embodiment, the convex portion 15b of the fixing plate 10 is engaged with the lower recess 2h of the mounting cup 2b, but the convex portion 15b of the fixing plate 10 may be engaged with the middle recess 2g.

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

Further, although the discharge tool 1 of the present embodiment is configured to be mounted on the container 2 having the two stems 2c, it can also be adopted for a double type container or a single type container.
