Description

[Technical Field]

[0001] The present invention relates to a discharge tool for an aerosol container. [Background technology]

[0002] In aerosol container discharge devices with a pair of stems, if the nozzle is not pressed down sufficiently, the contents may flow out from only one stem, or the flow rate of the contents flowing out from both stems may be significantly uneven. For this reason, some conventional aerosol container discharge devices use vibrations to let the user know that the nozzle operating part has been pressed down sufficiently (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2019-081605 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with conventional aerosol container dispensers, when the nozzle is pressed down sufficiently, the contents delivered to the discharge port are expelled all at once, which can result in the contents being expelled more than necessary.

[0005] On the other hand, it is possible to dispense a desired amount of contents by finely adjusting the depression of the nozzle. However, when finely adjusting the depression of the nozzle, it is possible that only one stem will operate, making it impossible to dispense multiple contents simultaneously.

[0006] An object of the present invention is to provide a discharge tool for an aerosol container that can simultaneously discharge a plurality of contents while suppressing the discharge speed of the contents sent out to the discharge port. [Means for solving the problem]

[0007] (1) The aerosol container discharge device according to the present invention is an aerosol container discharge device having a nozzle through which the contents sent through the stem of the aerosol container are discharged through a discharge port, the nozzle having a plurality of stem mounting recesses into which the stems can be mounted, the bottom wall of the stem mounting recesses having an inlet side opening that leads to the discharge port, and an emission control element that controls the discharge of the contents from the inlet side opening is arranged in the stem mounting recess, the emission control element further having a nozzle side fitting portion that fits into the stem mounting recess, a stem side fitting portion that can fit inside the stem, and a communication passage that connects the stem and the inlet side opening, and the fitting force of the nozzle side fitting portion is smaller than the fitting force of the stem side fitting portion.

[0008] (2) In the aerosol container discharge device of (1) above, the nozzle side fitting portion may include a main body that can be inserted into the stem mounting recess and a plurality of fitting protrusions arranged at intervals around the circumferential direction of the main body.

[0009] (3) In the aerosol container discharge device of (1) or (2) above, the stem side fitting portion may include a main body that can be inserted into the inside of the stem, and a plurality of fitting protrusions arranged at intervals around the circumferential direction of the main body.

[0010] (4) In the aerosol container discharge device described in any one of (1) to (3) above, the communicating passage may be constituted by an internal passage formed in the nozzle side fitting portion and a cutout passage formed in the stem side fitting portion and communicating with the internal passage.

[0011] (5) In the aerosol container discharge tool of (4) above, a portion of the internal passage may be closed by the stem-side fitting portion. [Effects of the Invention]

[0012] According to the present invention, it is possible to provide a discharge tool for an aerosol container that can simultaneously discharge a plurality of contents while suppressing the discharge speed of the contents sent out to the discharge port. [Brief explanation of the drawings]

[Figure 5C] FIG. 3 is a bottom view of the emission control element of FIG. 2. DETAILED DESCRIPTION OF THE INVENTION

[0014] In FIG. 1, reference numeral 1 denotes an aerosol container discharge tool (hereinafter, simply referred to as "discharge tool") according to one embodiment of the present invention. The discharge tool 1 is attached to an aerosol container 2 to form an aerosol device 3. In this embodiment, the aerosol device 3 can discharge a reaction product by mixing a plurality of contents. In this embodiment, the contents are a hair dye.

[0015] The aerosol container 2 includes a container body 4 containing the contents and a stem 5 protruding upward from the container body 4. The aerosol container 2 includes two stems 5 arranged side by side (only one stem 5 is shown in FIG. 1). In this embodiment, the aerosol container 2 is a double-barreled aerosol container. The double-barreled aerosol container 2 includes two container bodies 4 arranged side by side. That is, the double-barreled aerosol container includes two container bodies 4 arranged side by side and two stems 5 protruding upward from each of the two container bodies 4. However, the aerosol container 2 can also be a single-barreled aerosol container. Here, a single-barreled aerosol container refers to a container in which two container bodies 4 are formed by a single container body, and two stems 5 arranged side by side on the left and right protrude upward from the single container body.

[0016] In the present application, "downward" refers to the direction in which the stem 5 is pushed down (downward in FIG. 1), and "upward" refers to the opposite direction (upward in FIG. 1). In the present application, "left-right direction" refers to the direction in which the two stems 5 are aligned (left-right direction in FIG. 1), "forward" refers to the direction in which the discharge port A2 of the nozzle 11 is directed (forward in FIG. 1), and "rearward" refers to the opposite direction (depth in FIG. 1). In the drawings, the symbol O denotes the central axis of the aerosol device 3. In this embodiment, the central axis of the discharge tool 1, together with the central axis of the aerosol container 2, is the same axis as the central axis O of the aerosol device 3.

[0017] In this embodiment, the two container bodies 4 have the same configuration. However, the two container bodies 4 may have different configurations. Also, in this embodiment, the two stems 5 have the same configuration. In this embodiment, the two container bodies 4 contain different types of contents. As described above, these contents can be mixed to produce the desired effect. However, the two container bodies 4 may contain the same type of contents instead of different types of contents.

[0018] The stem 5 is a cylindrical member having a flow path R1 (hereinafter also referred to as "stem flow path R1") formed therein through which the contents are discharged. The stem 5 is biased upward. A check valve (not shown) is disposed within the container body 4. When the stem 5 is pressed downward against the upward biasing force, the check valve gradually opens in accordance with the amount the stem 5 is pressed down, and then becomes fully open at a predetermined pressed position. The stem 5 can discharge the contents at a flow rate corresponding to the opening of the check valve.

[0019] The discharge implement 1 has a nozzle 11 formed with a discharge outlet A2 for the contents and attached to two stems 5. The nozzle 11 discharges the contents sent through the stem 5 of the aerosol container 2 through the discharge outlet A2. The nozzle 11 has a plurality of stem mounting recesses C11 to which the stems 5 can be attached. The bottom wall 14 of the stem mounting recesses C11 has an inlet opening A1 that communicates with the discharge outlet A2. The inlet opening A1 is a through-hole formed in the bottom wall 14.

[0020] Fig. 2 shows a partial cross section of the main part of the discharge tool 1. Fig. 3 shows the main part of the discharge tool 1 of Fig. 2 with the emission control element 30, which will be described later, removed.

[0021] 3, in this embodiment, the nozzle 11 includes a nozzle body 12 in which a discharge port A2 is formed, and a connecting tube 13 provided in the nozzle body 12. An internal flow path R3 that communicates with the discharge port A2 is formed inside the nozzle body 12. The internal flow path R3 communicates with the stem mounting recess C11 through the inlet-side opening A1. In this embodiment, the stem mounting recess C11 is formed inside the connecting tube 13. In this embodiment, the bottom wall 14 of the stem mounting recess C11 is a partition wall that separates the nozzle body 12 and the connecting tube 13. In this embodiment, the nozzle 11 includes two connecting tubes 13 (only one connecting tube 13 is shown in the figure) that correspond to the stems 5 of the aerosol container 2.

[0022] Furthermore, in this embodiment, the nozzle body 12 is provided with a partition plate 15 in the center in the left-right direction that separates the internal flow path R3. This separates the internal flow path R3 in the nozzle 11 into two internal flow paths R3, each leading to one of the two inlet-side openings A1 and the other of the two inlet-side openings A1. In this embodiment, the partition plate 15 is configured so that the two separated internal flow paths R3 converge at the outlet A2. However, the partition plate 15 can also be configured to completely separate the outlet A2 into two outlets without merging them at the outlet A2. In other words, the outlet A2 of the nozzle 11 can be configured as two outlets, one leading to one of the two stems 5 and the other leading to the other of the two stems 5. Alternatively, the partition plate 15 can be omitted.

[0023] Furthermore, the nozzle 11 is composed of two parts for the purpose of cleaning the inside. In this embodiment, the nozzle body 12 is composed of an upper part 12a in which the discharge port A2 is formed, and a lower part 12b in which two connecting tubes 13 are provided. In this embodiment, the upper part 12a and the lower part 12b are attached so that they can be separated. According to this embodiment, the inside of the nozzle 11 can be easily cleaned by separating the upper part 12a and the lower part 12b.

[0024] In this embodiment, the nozzle 11 is formed by injection molding using a synthetic resin as a material. However, the material of the nozzle 11 is not limited to synthetic resin. The manufacturing method of the nozzle 11 is also not limited to injection molding. Furthermore, the shape of the nozzle body 12 is not limited to that shown in the drawings and can be designed as appropriate.

[0025] Referring next to FIG. 1, the discharge implement 1 includes a cover 20 that is attached to the container body 4 of the aerosol container 2 and covers the nozzle 11. The cover 20 is composed of three members: a fixed plate 21 that is attached to the container body 4; a peripheral wall cover 22 that is detachably attached to the fixed plate 21; and a top wall cover 23 that is attached to the upper inside of the peripheral wall cover 22. In this embodiment, each of the three members is formed by injection molding using a synthetic resin. However, the material of each of the three members is not limited to synthetic resin. The manufacturing method of the three members is also not limited to injection molding. Furthermore, the shapes of each of the three members are not limited to those shown in the drawings and can be designed as appropriate.

[0026] Furthermore, in this embodiment, the cover 20 is provided with an operating unit 24 that can push the nozzle 11 downward by swinging downward around a hinge (not shown) located on the front side. In this embodiment, the operating unit 24 is connected to the front wall 23a of the top cover 23 via the hinge. The operating unit 24 can push the nozzle 11 downward by swinging downward around the hinge.

[0027] FIG. 4 shows a partial cross-section of the aerosol container 2 with the main portion of the dispenser 1 (see FIG. 2) removed. In this embodiment, the fixed plate 21 has two side walls 21a that cover the mounting cups 7 of the two container bodies 4 from the left and right, respectively, and a top wall 21b that covers the upper surfaces of the mounting cups 7. The fixed plate 21 is attached to the mounting cups 7 of the two container bodies 4 by fitting. In this embodiment, the fixed plate 21 has two through holes A21 through which the respective stems 5 pass. The two through holes A21 are each formed in the top wall 21b. As a result, in this embodiment, when the two container bodies 4 are fixed to the fixed plate 21, the respective stems 5 can protrude upward from the fixed plate 21. However, the fixed plate 21 can be omitted from the cover 20. For example, the cover 20 can be configured such that the peripheral wall cover 22 is attached directly to the container body 4 without the fixed platen 21 being interposed therebetween.

[0028] Referring next to FIG. 1 , the peripheral wall cover 22 includes locking steps 25 that can be locked to the left and right sides of the fixed platen 21, respectively, and a detachment lever 26 that can release the locked state of the locking steps 25. In this embodiment, the detachment lever 26 is a cantilevered support piece formed by cutting out a downward U-shape from each of the left and right sides of the peripheral wall cover 22. In addition, in this embodiment, the locking steps 25 are steps formed by the cutouts that form the external shape of the detachment lever 26. Two locking protrusions 21c provided on the fixed platen 21 are engaged with the locking steps 25. The two locking protrusions 21c are respectively provided on the side walls 21a of the fixed platen 21. Therefore, by pushing the detachment lever 26 inward, the locking protrusions 21c can be released from the locking steps 25. As a result, in this embodiment, the peripheral wall cover 22 and the top wall cover 23 can be separated from the fixed platen 21, for example, as shown in FIG. 3 .

[0029] Furthermore, the peripheral wall cover 22 has an opening C22 cut out in a downward U-shape when viewed from the front, as shown in Fig. 3, for example. As a result, the discharge port A2 of the nozzle 11 is exposed to the front without being covered by the peripheral wall cover 22. Furthermore, the peripheral wall cover 22 has another opening cut out in a downward U-shape when viewed from the rear (as viewed from the depth of the drawing). As a result, the operating unit 24 is also exposed to the rear without being covered by the peripheral wall cover 22.

[0030] 3, an opening C23 is formed in the front wall 23a of the top cover 23, which is cut out in an upward inverted U shape when viewed from the front. As a result, the outlet A2 of the nozzle 11 is exposed to the front without being covered by the front wall 23a of the top cover 23. In other words, in this embodiment, the outlet A2 of the nozzle 11 is covered by the cover 20, but is exposed to the outside through the cover 20.

[0031] In addition, as shown in FIG. 2, a discharge restricting element 30 that restricts the discharge of the contents from the inlet opening A1 is disposed in the stem mounting recess C11.

[0032] Furthermore, the emission control element 30 has a nozzle side fitting portion 31 that fits into the stem mounting recess C11 and closes the inlet side opening A1, a stem side fitting portion 32 that can fit inside the stem 5, and a communication passage R2 that connects the stem flow path R1 and the inlet side opening A1.

[0033] In this embodiment, the emission control element 30 includes a nozzle-side fitting portion 31 and a stem-side fitting portion 32, and further includes a communication passage R2 formed in the emission control element 30. In this embodiment, the emission control element 30 is formed by injection molding using a synthetic resin as a material. However, the material of the emission control element 30 is not limited to synthetic resin. The manufacturing method of the emission control element 30 is also not limited to injection molding.

[0034] Additionally, in this embodiment, the discharge tool 1 is provided with two discharge regulating elements 30. One of the two discharge regulating elements 30 is disposed in one of the two stem mounting recesses C11, and the other of the two discharge regulating elements 30 is disposed in the other of the two stem mounting recesses C11. That is, in this embodiment, a discharge regulating element 30 is disposed in each of the two stem mounting recesses C11.

[0035] Furthermore, in the emission control element 30, the fitting force of the nozzle-side fitting portion 31 is smaller than the fitting force of the stem-side fitting portion 32. Therefore, in the aerosol device 3 of FIG. 1 , when the nozzle 11 is pulled upward relative to the aerosol container 2, the emission control element 30 separates from the nozzle 11 and remains on the stem 5 of the aerosol container 2.

[0036] As shown in FIG. 1 , in this embodiment, the flow path area (flow path area perpendicular to the flow direction of the contents) of the communication path R2 formed in the discharge control element 30 is smaller than the flow path area of ​​the stem flow path R1 formed in the stem 5 and smaller than the flow path area of ​​the inlet-side opening A1 formed in the nozzle 11. In other words, the communication path R2 is a throttle flow path (orifice flow path) that connects the stem flow path R1 and the inlet-side opening A1. Therefore, the flow rate of the contents discharged through the stem flow path R1 is slowed by passing through the communication path R2. In other words, the contents discharged from the discharge port A2 are discharged at a lower flow rate than when discharged through the stem flow path R1. In other words, according to this embodiment, by arranging the discharge control elements 30 in each of the two stem mounting recesses C11, the discharge speed (flow rate) of the two contents discharged from the discharge port A2 can be suppressed. Therefore, even if the operating unit 24 is pressed down all at once, the two contents are slowly discharged from the discharge port A2.

[0037] As described above, according to this embodiment, it is not necessary to slowly press down the operating unit 24 to slowly discharge the contents. In addition, in this embodiment, a discharge restriction element 30 is disposed in each of the two stem mounting recesses C11. Therefore, unlike conventional discharge devices, it is not necessary to slowly press down the operating unit 24 while paying attention to the discharge speed from one of the two stems. Therefore, according to this embodiment, by pressing down the operating unit 24 (nozzle 11) sufficiently and all at once, it is possible to simultaneously discharge multiple contents without operating only one of the stems 5.

[0038] That is, the user can fully and quickly press down the nozzle 11 without worrying about the contents being ejected all at once. As a result, according to this embodiment, multiple contents can be ejected simultaneously without operating only one of the stems 5.

[0039] Therefore, according to this embodiment, it is possible to provide a discharge tool for an aerosol container that can simultaneously discharge a plurality of contents while suppressing the discharge speed.

[0040] Specifically, when dispensing hair dye (contents) from an aerosol container onto a brush or the like using a conventional dispenser, more hair dye than necessary may be dispensed all at once, raising concerns that the hair dye may overflow from the brush and stain the surrounding area.

[0041] In contrast, in the present embodiment, even if the operating portion 24 (nozzle 11) is pressed down in one go, the hair dye is discharged slowly from the discharge port A2 because the discharge speed of the hair dye is suppressed, which prevents the hair dye from spilling out of the brush and soiling the surrounding area.

[0042] In addition, while conventional discharge devices require careful depressing operations, this embodiment does not require such careful depressing operations, thereby reducing operational stress that may be experienced by the user.

[0043] Furthermore, when using a conventional dispenser, the two agents from the two stems 5 may not be dispensed (mixed) simultaneously depending on how hard the operating portion 24 (nozzle 11) is pressed down. In this case, there is a concern that this may affect the quality of the hair dye dispensed from the discharge port A2.

[0044] In contrast, in the present embodiment, the two agents are simultaneously ejected (mixed) without adjusting the pressure on the operating portion 24 (nozzle 11). As a result, a hair dye of stable quality can be ejected from the ejection port A2.

[0045] If the internal structure of the aerosol container dispenser is symmetrical, it is preferable to place the same emission control element 30 in each of the two stem mounting recesses C11. If the internal structure of the aerosol container dispenser is asymmetrical, it is preferable to place different emission control elements 30 in each of the two stem mounting recesses C11. However, if the internal structure of the aerosol container dispenser is symmetrical, different emission control elements 30 can be placed. If the internal structure of the aerosol container dispenser is asymmetrical, it can be placed the same emission control element 30. By using the emission control element 30, the discharge speed of the content delivered from the discharge port A2 can be adjusted by appropriately setting the flow path area, length, path, etc. of the communicating passage R2.

[0046] Additionally, in the emission control element 30, the fitting force of the nozzle-side fitting portion 31 is smaller than the fitting force of the stem-side fitting portion 32. Therefore, in the aerosol device 3 of FIG. 1, when the discharge tool 1 is separated into its main part (FIG. 3) and the remaining part (FIG. 4), the emission control element 30 remains on the stem 6 as shown in FIG. 4. In other words, when the discharge tool 1 is separated, the emission control element 30 does not remain in the stem mounting recess C11 of the nozzle 11 as shown in FIG. 3. Therefore, a cleaning bellows container 40 can be attached to the stem mounting recess C11 of the nozzle 11 as in the conventional case. In other words, according to this embodiment, the emission control element 30 does not get in the way when cleaning the inside of the nozzle 11. Therefore, according to this embodiment, cleaning can be performed in the conventional manner.

[0047] The aerosol device 3 is generally sold to consumers (including manufacturers and retailers) in a box containing a set of an aerosol container 4 and a fixed plate 21 (see FIG. 4; hereinafter, simply referred to as the "aerosol container") and the discharge implement 1 (see FIG. 2; hereinafter, simply referred to as the "cover with an operating unit") other than the fixed plate 21. In this embodiment, the emission control element 30 is distributed in a state set in the connecting tube 13 of the cover with an operating unit, as shown in FIG. 2. That is, the emission control element 30 is set in the cover with an operating unit in advance by fitting the nozzle-side fitting portion 31 to the connecting tube 13 of the cover with an operating unit. Therefore, when a consumer uses the aerosol device 3, the consumer sets the cover with an operating unit on the aerosol container, thereby fitting the stem-side fitting portion 32 of the emission control element 30 inside the stem 5. This allows the user to use the aerosol device 3. During cleaning, as described above, the discharge control element 30 is moved to the stem 5 of the aerosol container simply by removing the cover with the operating portion.

[0048] 5A to 5C show an emission control element 30 according to this embodiment. In the drawings, reference symbol O3 denotes the central axis of the emission control element 30.

[0049] 5A shows a plan view seen from above of the emission control element 30. In this embodiment, the nozzle side fitting portion 31 includes a main body 31a (hereinafter also referred to as the "nozzle side fitting portion main body 31a") that can be inserted into the stem mounting recess C11, and a plurality of fitting protrusions 31b that are spaced apart in the circumferential direction of the nozzle side fitting portion main body 31a.

[0050] In this embodiment, as shown in FIG. 5A, the nozzle-side fitting body 31a has a perfect circular shape in plan view, with the center point being the central axis O3 (hereinafter also simply referred to as "axis O3") of the emission control element 30, and the shape is the same as the inner diameter of the stem mounting recess C11. Furthermore, the nozzle-side fitting body 31a has an internal passage R21, which will be described later. The fitting protrusions 31b protrude radially outward from the nozzle-side fitting body 31a. The fitting protrusions 31b are arranged circumferentially around the axis O3 at intervals. In this embodiment, the nozzle-side fitting body 31 has three fitting protrusions 31b.

[0051] FIG. 5B is a cross-sectional view taken along the line X-O3-X of FIG. 5A. As shown in FIG. 5B, the axial length L2 of the fitting protrusion 31b is shorter than the axial length L1 of the nozzle side fitting body 31a. In this embodiment, the nozzle side fitting body 31a has a cylindrical shape with a constant diameter along the axial direction. In this embodiment, the internal passage R21 is a through-hole formed in the nozzle side fitting body 31a. The internal passage R21 penetrates the nozzle side fitting body 31a in the axial direction.

[0052] 5C shows a plan view seen from below of the emission control element 30. In this embodiment, the stem side fitting portion 32 includes a main body 32a (hereinafter also referred to as the "stem side fitting portion main body 32a") that can be inserted into the stem flow path R1, and a plurality of fitting protrusions 32b that are spaced apart in the circumferential direction of the stem side fitting portion main body 32a.

[0053] In this embodiment, as shown in FIG. 5C , the stem-side fitting body 32a has a perfect circular shape in a plan view, centered on the axis O3, with a diameter similar to the inner diameter of the stem flow channel R1. Furthermore, the stem-side fitting body 32a includes a cutout passage R22. In this embodiment, the cutout passage R22 is a flat surface formed in the stem-side fitting body 32a. However, the cutout passage R22 may be a groove formed in the stem-side fitting body 32a. The fitting protrusions 32b protrude radially outward from the stem-side fitting body 32a. The fitting protrusions 32b are spaced apart circumferentially around the axis O3. In this embodiment, the stem-side fitting body 32 includes seven fitting protrusions 32b. That is, in this embodiment, the number of fitting protrusions 32b of the stem-side fitting body 32 is greater than the number of fitting protrusions 31b of the nozzle-side fitting body 31.

[0054] 1, in this embodiment, the fitting protrusion 31b provided on the nozzle-side fitting portion 31 of the emission control element 30 fits into the stem mounting recess C11 of the nozzle 11, specifically, the inner circumferential surface of the connecting tube 13 of the nozzle 11. Also, in this embodiment, the fitting protrusion 32b provided on the stem-side fitting portion 32 of the emission control element 30 fits into the stem flow path R1 of the stem 5, specifically, the inner circumferential surface of the stem 5.

[0055] As shown in FIGS. 5A to 5C , if the nozzle-side fitting portion 31 is provided with multiple fitting protrusions 31b, the fitting force of the nozzle-side fitting portion 31 can be easily adjusted by, for example, the number, axial length, and circumferential width of the fitting protrusions 31b. Furthermore, if the stem-side fitting portion 32 is provided with multiple fitting protrusions 32b as in this embodiment, the fitting force of the stem-side fitting portion 32 can be easily adjusted by, for example, the number, axial length, and circumferential width of the fitting protrusions 32b. In this embodiment, the number of fitting protrusions 31b of the nozzle-side fitting portion 31 is smaller than the number of fitting protrusions 32b of the stem-side fitting portion 32. In this case, the fitting force of the nozzle-side fitting portion 31 can be easily made smaller than the fitting force of the stem-side fitting portion 32. Furthermore, in this embodiment, the nozzle side fitting portion 31 suppresses the fitting force of the nozzle side fitting portion 31 by making the axial length L2 of the fitting protrusion 31b shorter than the axial length L1 of the nozzle side fitting portion main body 31a.

[0056] However, the nozzle-side fitting portion 31 may omit the fitting protrusion 31b. In this case, the nozzle-side fitting portion 31 directly fits the nozzle-side fitting portion main body 31a into the stem mounting recess C11. The stem-side fitting portion 32 may also omit the fitting protrusion 32b. In this case, the stem-side fitting portion 32 directly fits the stem-side fitting portion main body 32a into the inside of the stem 5. In this case, the fitting force can be adjusted, for example, by the surface roughness of the nozzle-side fitting portion main body 31a and the surface roughness of the stem-side fitting portion main body 32a.

[0057] 5B, in this embodiment, the stem side fitting body 32a is tapered toward the tip (downward), which allows the stem side fitting portion 32 to be easily inserted into the stem 5.

[0058] Furthermore, in this embodiment, the communication passage R2 is composed of an internal passage R21 formed in the nozzle-side fitting portion 31 and a cut-out passage R22 formed in the stem-side fitting portion 32 and communicating with the internal passage R21. In this case, the shape, dimensions (flow path area), etc. of the internal passage R21 and the shape, dimensions (flow path area), etc. of the cut-out passage R22 can be adjusted separately. Therefore, in this case, a desired discharge speed can be easily obtained by adjusting the internal passage R21 and the cut-out passage R22 separately.

[0059] 5A and 5B, a portion of the internal passage R21 is closed by the stem-side fitting portion 32. In this case, the content passes through the communication passage R2, thereby effectively reducing the discharge speed.

[0060] The above describes an aerosol container dispenser according to one embodiment of the present invention, but the present invention is not limited to the above embodiment and can be modified in various ways within the scope of the claims. For example, in this embodiment, the contents are described as hair dye, but the present invention is not limited to this. Furthermore, in this embodiment, the two contents are described as reacting (chemically) when mixed with each other, but the two contents can be mixed without reacting with each other. Furthermore, as described above, the aerosol container dispenser can be configured to dispense the two contents without mixing them with each other. [Explanation of symbols]
