Description

The present invention relates to an aerosol container discharge tool mounted on an aerosol container.

Conventionally, there is known an aerosol container in which a pressurized gas is stored together with the contents and the contents are discharged from the stem to the outside by pushing down the stem. As such an aerosol container, a single type container in which one content is housed in one container and one stem, and a double type container in which single type containers are arranged side by side to form a set. In addition, there is a type in which two types of contents are separately stored in one container and two stems are provided.

In any type of aerosol container, a discharge tool is generally attached to facilitate the operation of discharging the contents. As the discharge tool for the aerosol container, for example, as described in Patent Document 1, a nozzle detachably attached to the stem, a fixing plate fixed to the mounting cup of the aerosol container, and a fixing plate detachably attached to the fixing plate are attached. It has a cover member that covers the nozzle, and by pushing down the operation unit provided on the cover member, the stem can be pushed down together with the nozzle so that the contents can be discharged from the nozzle to the outside. Things are known.

In the conventional aerosol container discharge tool, the cover member is removable from the fixing plate so that the nozzle can be removed from the stem during cleaning after use. That is, on both the left and right sides of the cover member nozzle, the elastic plate pieces formed by a pair of vertical slits that cut out the side walls of the cover member from the lower end, and the outer surface on the lower end side of the elastic plate pieces are provided. A holding claw portion having an outer protrusion is provided, and the cover member can be held by the fixing plate by engaging and disengaging the outer protrusion with a locking hole provided in the fixing plate. The cover member can be removed from the fixing plate by pushing the elastic plate piece inward to release the engagement between the outer protrusion and the locking hole.

Japanese Unexamined Patent Publication No. 2015-209268

In the above-mentioned conventional aerosol container discharge tool, the length of the pair of vertical slits forming the elastic plate piece is increased to reduce the operating force of the elastic plate piece required when removing the cover member, and the cover member. Can be easily removed.

However, if the operating force of the elastic plate piece required to remove the cover member is set small, when the aerosol container is held with one hand and the operation part is pushed down with the index finger, the other fingers supporting the container will be the elastic plate piece. The elastic plate piece is easily pushed in by touching the cover member, which causes a problem that the cover member may be unexpectedly detached from the fixing plate.

Further, since the conventional aerosol container discharge tool has a configuration in which the operation portion is integrally provided on the upper part of the cover member, when the operation portion is pushed down to discharge the contents, the reaction is caused. A force that pulls this upward is applied to the cover member, but at the same time, there are some that the lower end edges on both the left and right sides of the cover member that sandwich the nozzle are deformed inward so as to narrow the width. In this case, in particular, when the aerosol container is held with one hand and the operation portion is pushed down with the index finger, the left and right sides of the cover member nozzle are supported by the other fingers, so that the cover member nozzle is supported. The lower end edges on both the left and right sides of the sandwich will be deformed more greatly. Therefore, when the operation portion is pushed down to discharge the contents, the amount of engagement (engagement amount) of the holding claws provided on the left and right sides of the cover member with the locking holes is reduced, and the cover is covered. The member is in a state where it can easily come off from the fixed plate. In such a situation, when the operating force of the elastic plate piece required for removing the cover member is set small, the above-mentioned problems will occur more prominently.

As shown in FIG. 5, a pair of vertical slits 26 that lack the outer peripheral wall 25 from the lower end are provided on the right side of the outer peripheral wall 25 as the side wall. Each of these vertical slits 26 extends straight upward from the lower end of the outer peripheral wall 25 in a predetermined groove width in parallel with the axial direction (vertical direction) of the container 2, and is spaced apart from each other in the circumferential direction. They are arranged to form elastic plate pieces 27 between each other.

The elastic plate piece 27 has a rectangular plate shape, is integrally connected to the outer peripheral wall 25 at the upper end thereof, and can be elastically deformed in the left-right direction (inside and outside directions of the cover member 20) with the upper end as a fulcrum. It has become. Further, as shown in FIG. 4, the lower end of the elastic plate piece 27 projects downward from the lower end of the outer peripheral wall 25, and the outer protrusion 28 is integrally provided on the outer surface on the lower end side thereof. In the present embodiment, the outer protrusion 28 is provided slightly above the lower end of the elastic plate piece 27, but the outer protrusion 28 may be provided at the lower end of the elastic plate piece 27. Further, stopper protrusions 29 are integrally provided on the upper side of the outer protrusion 28 at a predetermined distance (slightly larger than the plate thickness of the lower flange 16b).

The outer protrusion 28 is inserted into a locking hole 18 provided in the fixing plate 10 and is detachably locked to the locking hole 18 by engaging with the lower side surface of the lower flange 16b.

The elastic plate piece 27 and the outer protrusion 28 form a holding claw portion T on the right side of the outer peripheral wall 25 of the cover member 20. The holding claw portion T is similarly provided on the left side of the outer peripheral wall 25, and the fixing plate 10 is provided with a locking hole 18 corresponding to the holding claw portion T on the left side. That is, the cover member 20 is provided with two holding claws T facing each other on the left and right sides of the nozzle 30.

The outer protrusion 28 of each holding claw portion T is locked in the corresponding locking hole 18, so that the cover member 20 is held in a state of being attached to the fixing plate 10. On the other hand, by pushing the elastic plate piece 27 toward the inside of the cover member 20, the engagement between the outer protrusion 28 and the locking hole 18 can be released, and the cover member 20 can be removed from the fixing plate 10.

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 and 4 are formed. The nozzle 30 is detachably attached to the stem 2c of the container 2 and can be removed from the stem 2c when cleaning or the like is performed after use.

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, and the distance between the left and right sides of the annular portion 32e is longer than the distance from the front side to the back side. Further, as shown in FIG. 4, a pair of intermediate walls 32f are provided at intervals 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 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. 4, 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 plate piece 27 and bends downward from the direction toward the elastic plate piece 27. By providing such a locking leg portion 32i in the guide cylinder portion 32h, the nozzle 30 with respect to the fixing plate 10 is based on the positional relationship between the locking leg portion 32i and the locking hole 18 of the fixing plate 10. The mounting angle in the rotation direction can be visually confirmed. Therefore, the provision of the locking leg portion 32i facilitates the positioning of the nozzle 30 when the nozzle 30 is mounted on the stem 2c. Further, these locking legs 32i are provided with inner protrusions 32k that are inserted into the locking holes 18 of the fixing plate 10 and locked to the inner edges of the locking holes 18. Therefore, these locking legs 32i are inserted into the locking holes 18 and undercut engaged with the upper flange 15 of the fixing plate 10 by the inner protrusion 32k to prevent the nozzle 30 from falling off from the stem 2c. Can be done.

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, semi-circular ribs 33c that are semi-circular in side view are provided (in the present embodiment, a total of two are spaced apart in the left-right direction), and the box-shaped portion 33a. On the front side of 33a, a tubular portion 33e is provided whose tip opening is a discharge port 33d to the outside world of the contents. In the present embodiment, the partition wall 33b extends toward the discharge port 33d from the boundary between the box-shaped portion 33a and the tubular portion 33e. Further, on the lower side of the tubular portion 33e, an upper engaging portion 33f having a claw shape corresponding to the lower engaging portion 32g is provided.

Then, the nozzle 30 is bent along the hinge 31 as described above, so that the lower engaging portion 32g and the upper engaging portion 33f are engaged with each other to maintain the folded state in half. Further, 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 between the paired intermediate walls 32f. Sandwiched, this internal space is divided into two spaces, each of which is connected to a through hole 32c. Further, these two spaces meet inside the tubular portion 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.

As shown in FIGS. 2 to 5, guard portions 40 are provided on both the left and right sides of the cover member 20 in order to prevent the holding claw portions T from being unexpectedly operated. Each of the pair of guard portions 40 has a pair of vertical ribs 41 and one horizontal rib 42 connecting the vertical ribs 41.

One vertical rib 41 is provided integrally with the outer peripheral wall 25 at the edge of the outer peripheral wall 25 along the one vertical slit 26, and extends straight in parallel with the axial direction (vertical direction) of the container 2. .. Similarly, the other vertical rib 41 is provided integrally with the outer peripheral wall 25 at the edge of the outer peripheral wall 25 along the other vertical slit 26, and is straight in parallel with the axial direction (vertical direction) of the container 2. It is extending. Further, each of the pair of vertical ribs 41 projects outward from the outer surface of the outer peripheral wall 25 at a predetermined height. The lower end of each vertical rib 41 reaches the lower end edge of the outer peripheral wall 25, and the upper end of each vertical rib 41 reaches a position slightly above the upper end of the vertical slit 26.

The horizontal rib 42 extends in parallel with the circumferential direction (direction orthogonal to the vertical slit 26) of the outer peripheral wall 25 of the cover member 20, and is connected to the upper end of one vertical rib 41 at one end and the other vertical rib at the other end. It is arranged so as to be connected to the upper end of 41 and slightly above the upper end of the elastic plate piece 27. Further, the horizontal ribs 42 project outward from the outer surface of the outer peripheral wall 25 at the same height as the pair of vertical ribs 41. In this way, the guard portion 40 has an inverted U shape that surrounds the left and right sides and the upper side of the elastic plate piece 27 of the holding claw portion T, and the elastic plate piece 27 is inside the guard portion 40 to the outside. It is exposed.

The guard portion 40 can be used as a finger hooking portion on which a finger can be hung (mounted) on the left and right sides of the outer peripheral wall 25 of the cover member 20 when the contents are discharged from the container 2. It is formed in a shape or size that can prevent a finger from unexpectedly touching the elastic plate piece 27. Further, in the guard portion 40, the area of the opening portion (the opening portion that exposes the elastic plate piece 27 to the outside) surrounded by the guard portion 40 and the upper surface of the lower flange 16b of the fixing plate 10 is formed by a finger through the opening portion. The elastic plate piece 27 is formed in a shape or size so as to be large enough to be pushed toward the inside of the cover member 20.

As described above, in the aerosol container discharge tool 1, since the cover member 20 is provided with the guard portion 40 having the above configuration, a pair of fingers supporting or gripping the cover member 20 when discharging the contents from the container 2 is provided. It is placed on the vertical rib 41 of the above, and the pad of the finger is prevented from unexpectedly touching the elastic plate piece 27 by hitting the horizontal rib 42. Therefore, it is possible to prevent the holding claw portion T from being disengaged from the fixing plate 10, whereby the cover member 20 is released from the fixing plate 10 when the contents are discharged from the container 2. It is prevented that the contents are unexpectedly disengaged and the contents cannot be discharged.

In particular, even when the length of the pair of vertical slits 26 forming the elastic plate piece 27 is set to be long and the operating force of the elastic plate piece 27 required to remove the cover member 20 is reduced, the guard portion The 40 prevents the finger supporting or gripping the cover member 20 from unexpectedly touching the elastic plate piece 27, thereby surely preventing the cover member 20 from unexpectedly coming off from the fixing plate 10, and a pair of vertical lengths. The length of the slit 26 can be set to be long to facilitate the work of removing the cover member 20.

Further, in the aerosol container discharge tool 1 having the above configuration, since the operation unit 23 is integrally provided on the upper part of the cover member 20, when the operation unit 23 is pushed down to discharge the contents, the operation unit 23 is pushed down. Due to the reaction, a force for pulling the cover member 20 upward is applied to the cover member 20. At the same time, the lower end edges of the cover member 20 on both the left and right sides of the nozzle 30 are deformed inward so as to narrow the width (the lower end edge is deformed from a circular shape to an elliptical shape having a short diameter in the left-right direction). It will be. Further, when the container 2 is held by one hand and the operation unit 23 is pushed down by the index finger, the left and right sides of the cover member 20 sandwiching the nozzle 30 are supported or gripped by the other fingers. The lower end edge portions on both the left and right sides of the member 20 sandwiching the nozzle 30 are more deformed. Then, due to these factors, when the operation portion 23 is pushed down to discharge the contents, the locking holes 18 of the holding claw portions T (outer protrusions 28) provided on the left and right sides of the cover member 20 are provided. The amount of engagement (hanging amount) with the cover member 20 is reduced, and the cover member 20 is easily disengaged from the fixing plate 10. However, in the aerosol container discharge tool 1 of the present embodiment, as described above, the guard portion 40 prevents the finger supporting or gripping the cover member 20 from unexpectedly touching the elastic plate piece 27 when the contents are discharged. Since it can be prevented, it is possible to surely prevent the cover member 20 from being unexpectedly detached from the fixing plate 10.

As shown in FIGS. 2 to 5, a pair of flange portions 43 connected to the lower ends of the vertical ribs 41 are provided at the lower end edges of the outer peripheral wall 25 of the cover member 20. Each of these flange portions 43 extends in the circumferential direction from the lower end of the vertical rib 41 toward the side opposite to the vertical slit 26, and the protruding height from the outer surface of the outer peripheral wall 25 toward the outside is the vertical rib 41. Is the same as.

By providing such a flange portion 43, it is possible to make it easier for the fingers that support or grip the left and right sides of the cover member 20 to be further hooked on the guard portion 40.

It should be noted that the flange portion 43 may not be provided.

When attaching the aerosol container discharge tool 1 configured as described above to the container 2, the fixing plate 10 is first attached to the mounting cup 2b, and then the nozzle 30 assembled in a folded state is mounted on the cylindrical portion from above. Attach 32b while aligning it with the stem 2c. Next, the cover member 20 is inserted from above with the holding claw portion T aligned with the locking hole 18 while projecting the tubular portion 33e of the nozzle 30 from the window hole 25b, and is attached to the fixing plate 10. .. Here, since the outer protrusion 28 of the holding claw portion T is provided with an inclined surface 28a, when the cover member 20 is pushed against the fixing plate 10, the inclined surface 28a of the outer protrusion 28 becomes the inner circumference of the lower flange 16b. The elastic plate piece 27 abuts on the surface and is guided inward in the radial direction and is inserted into the locking hole 18 while bending. Then, the cover member 20 is detachably attached to the fixing plate 10 by engaging the outer protrusion 28 with the lower surface of the lower flange 16b.

After the installation of the cover member 20 is completed, the lower end of the cover member 20 and the lower surface of the stopper protrusion 29 of the elastic plate piece 27 come into contact with the upper surface of the lower flange 16b of the fixing plate 10, and the cover member 20 is attached to the fixing plate 10. It is held stably and wobbling during use is suppressed. 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 may be placed on the upper surface of the operation unit 23 and the contents may be pushed downward. As a result, 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, the two stems 2c are pushed down together with the nozzle 30, and two types of contents in the container 2 are provided. An object is ejected from each of the stems 2c at the same time, and is discharged to the outside from the discharge port 33d through the passage R formed inside the nozzle 30.

On the other hand, when the nozzle 30 is removed from the container 2 for cleaning after use, the elastic plate piece 27 of the holding claw portion T is pushed inward (inward in the radial direction) of the holding claw portion T through the guard portion 40. , The outer protrusion 28 is disengaged from the locking hole 18. At this time, since the elastic plate piece 27 can be easily elastically deformed by setting the vertical slit 26 to be long, the work of removing the cover member 20 from the fixing plate 10 is easy. When the cover member 20 is removed from the fixing plate 10, the nozzle 30 is exposed to the outside, so that the nozzle 30 can be easily attached to and detached from the container 2. After cleaning the nozzle 30, the nozzle 30 and the cover member 20 may be reattached according to the procedure described above.

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 above embodiment, the case where the present invention is applied to the discharge tool 1 mounted on the container 2 having two stems 2c is shown, but for example, the invention is mounted on a single type container or a double type container. The present invention may be applied to the discharge tool to be used.

Further, in the above-described embodiment, the holding claw portion T and the guard portion 40 are provided on the left and right sides of the cover member 20, respectively, but at least one holding claw portion T and the guard portion 40 cover the cover member 20. If the member 20 is provided, its position and number can be changed in various ways.

Further, in the above embodiment, the lateral rib 42 of the guard portion 40 has a shape extending parallel to the circumferential direction of the outer peripheral wall 25, but the present invention is not limited to this, and the cover member 20 is not limited to this, and the cover member 20 is discharged when the contents are discharged from the container 2. If the shape is such that a finger that supports or grips both the left and right sides of the outer peripheral wall 25 can be hung and an opening portion that enables a pushing operation of the elastic plate piece 27 can be secured, for example, the circumferential direction of the outer peripheral wall 25. The shape can be variously changed, for example, the shape is formed so as to be inclined and extended, or the shape is formed so as to extend in the circumferential direction while being curved upward or downward between the pair of vertical ribs 41.

Further, in the above-described embodiment, the horizontal ribs 42 are connected to the upper ends of the pair of vertical ribs 41, but for example, the horizontal ribs 42 may be provided separately without being connected to the pair of vertical ribs 41. Alternatively, the pair of vertical ribs 41 may be connected to the intermediate portion in the vertical direction. Further, the protruding height of the outer peripheral wall 25 of the horizontal rib 42 from the outer surface may be different from the protruding height of the pair of vertical ribs 41.
