  The double aerosol product 10 in FIG. 1 is one in which the contents of a different color are discharged (injected) when the remaining amount of the contents becomes constant, and the inner bag has flexibility. 11, a bottomed cylindrical pressure-resistant container 12 that accommodates the inner bag 11, an aerosol valve 13 (hereinafter referred to as a valve) that closes the opening of the inner bag 11 and the pressure-resistant container 12, and contents filled in the inner bag 11 It consists of the thing A and the propellant B with which it fills between the inner bag 11 and the pressure | voltage resistant container 12. FIG.

As shown in FIG. 2a, the inner bag 11 has a cylindrical body 11a and a bottom 11 that closes the lower end thereof.
b, a tapered shoulder portion 11c formed at the upper end of the body portion 11a, a cylindrical neck portion 11d formed at the upper end of the shoulder portion 11c, and a flange portion 11e formed at the upper end of the neck portion 11d. It consists of. A ring-shaped reinforcing member 15 is fixed to the outer periphery of the lower portion or the lower end of the body portion 11a. That is, in the inner bag 11, the lower portion of the body portion 11 a is reinforced by the reinforcing member 15, and the lower portion of the body portion 11 a serves as a reinforcing portion, and when the double aerosol product 10 is operated, The lower part of the part 11a is deformed last.
Further, the reinforcing member 15 may be fixed or arranged on the inner peripheral surface of the lower portion of the inner bag as indicated by an imaginary line 15a. In this case as well, the lower portion of the body portion 11a of the inner bag 11 is a strengthened portion.

Returning to FIG. 1, the pressure vessel 12 is an integrally molded product including a trunk portion 12 a, a bottom portion 12 b, a shoulder portion 12 c, and a bead portion 12 d. However, other pressure-resistant containers may be used.
The valve 13 includes a cylindrical housing 13a, a stem 13b accommodated in the housing so as to be movable up and down, a spring 13c that constantly urges the stem 13b upward, and a stem rubber 13d that closes the stem hole of the stem 13b. And a mounting cup 13e that covers the upper part of the housing 13a and is fixed to the pressure vessel 12. A communication hole 13f is formed at the lower end of the housing 13a. When the valve 13 is opened by lowering the stem 13b, the contents A are introduced into the housing 13a through the communication hole 13f and further discharged from the stem 13b. .

The content A is a gel or cream having viscosity, or a foaming gel or cream that foams after discharge, and the main color content A1 that is discharged in a state where the remaining amount of the content is sufficient, and the content The final color content A2 is discharged in a state where the remaining amount of the product is small. The main color content A1 and the final color content A2 are different in color but have the same main component (effect). Therefore, the user can recognize the remaining amount from the color of the discharged contents.
In this embodiment, the content A is filled in two upper and lower layers, the final color content A2 on the bottom, and the main color content A1 on the top. Further, the final color content A2 is filled only in a portion surrounded by the lower portion of the trunk portion 11a whose strength is enhanced by the reinforcing member 15 of the inner bag 11. The ratio of the main color content A1 and the final color content A2 of the content A is:
50/50 to 90/10, preferably 60/40 to 80/20. If the main color content A1 is more than 90% (the final color content A2 is less than 10%), the necessary amount may not be left when the user recognizes the color change, and is used up during use. . Even if the main color content A1 is smaller than 50%, the role of the final color content A2 that informs the remaining amount is weakened. When a viscous content is used, the viscosity is 500 to 100,000 (mPa · s), preferably 1,000 to 80,000 (mPa · s). If it is greater than 100,000 (mPa · s), air is likely to be mixed between the main color content A1 and the final color content A2 and may be scattered during use. If it is smaller, the main color content A1 and the final color content A2 are mixed in the inner bag.
Examples of such contents A include hair care agents such as hair dyes and treatment agents, skin care agents such as humectants, packs, and cleansings.
As the propellant B, a liquefied gas such as liquefied petroleum gas or dimethyl ether, or a compressed gas such as nitrogen, nitric oxide, oxygen, or air is used.

  Since the aerosol product 10 is configured in this manner, the main color content A1 is discharged first, the main color content A1 is discharged, and then the final color content A2 is discharged. That is, at first, other than the lower part of the body part 11a of the inner bag 11 is deformed by the propellant, and finally, the lower part (strengthened part) of the body part 11a is deformed. Therefore, the user can recognize that the remaining amount is small when the final color content A2 is discharged.

The inner bags 16 a to 16 c in FIGS. 2 b to 2 d can be used instead of the inner bag 11.
The inner bag 16a of FIG. 2b has the trunk | drum 11a, the bottom part 11b, the shoulder part 11c, the neck part 11d, and the flange part 11e similarly to the inner bag 11, The difference with the inner bag 11 is the trunk | drum 11a. The diameter of the lower part 17a is a thin point compared with the trunk | drum 11a.
The inner bag 16b of FIG. 2c has the trunk | drum 11a, the bottom part 11b, the shoulder part 11c, the neck part 11d, and the flange part 11e similarly to the inner bag 11, The difference with the inner bag 11 is the trunk | drum 11a. The thickness of the lower part 17b is thick compared with the trunk | drum 11a.
The inner bag 16c of FIG. 2d has a trunk portion 11a, a bottom portion 11b, a shoulder portion 11c, a neck portion 11d, and a flange portion 11e as in the case of the inner bag 11, and the difference from the inner bag 11 is that of the trunk portion 11a. A fold line extending in the vertical direction is formed at the central portion 18 (a portion where the lower portion 17c is left).
Each of the inner bags 16a to 16c in FIGS. 2b to 2d has a lower strength of the body portion 17a to 17c with respect to an external force than other portions of the body portion, and serves as a reinforcing portion. Therefore, even if any inner bag 16a-16c is pressed with a propellant, parts other than the lower part 17 of a trunk | drum will deform | transform initially, and the lower parts 17a-17c of a trunk | drum will finally deform | transform. By filling the final color contents A2 in the lower portions 17a to 17c of these inner bags 16a to 16c and filling the main color contents A1 in other parts, the same effect as the aerosol product 10 can be obtained.

  In the aerosol product 20 of FIG. 3, the inner bag 21 is provided with a bellows 21a that acts as a reinforcing part at the lower end. The outer diameter of the bellows 21a is made thinner than the outer diameter of the trunk. The pressure vessel 12 is an integrally molded product having a trunk portion, a bottom portion, a shoulder portion, and a neck portion, and an annular recess 12f is provided in the lower portion of the neck portion. The upper end of the neck portion 12 extends straight. Further, the valve 13 includes a lid 13g that covers the upper portion of the housing 13a and closes the pressure vessel, and a cap 13h that is provided on the lid and is fixed to the pressure vessel. Other configurations are substantially the same as the valve of FIG.

In the aerosol product 20, the inner bag 21 is inserted into the pressure vessel 12 with the bellows 21a expanded in the axial direction, and in this state, the final color content A2 and the main color content A1 are sequentially filled. Therefore, as shown in FIG. 4, the final color content A2 is filled slightly below the upper end of the bellows 21a. Even in this state, the bellows 21 a of the inner bag is in an expanded state, so that the upper end 21 b of the inner bag 21 is located above the upper end of the pressure vessel 12. In this state, the lid 13g of the valve 13 is inserted into the inner bag 21. Since the upper end 21b of the inner bag is above the upper end of the pressure vessel 12, the valve 13 can be easily inserted. After fitting the valve 13 in the inner bag 21, the lid 13g is pushed down to close the pressure-resistant container 12. At this time, as shown in FIG. 3, the bellows 21a of the inner bag 21 is contracted in the axial direction. The contracted bellows 21a acts as a strengthened portion because the strength against radial pressing increases. In addition, since the outer diameter of a bellows is made thinner than the trunk | drum, a reinforcement | strengthening part becomes still stronger. Finally, the lid 13g is fixed with the cap 13h.
As described above, the aerosol product 20 has the bellows 21a widened in the manufacturing stage, facilitating the manufacture thereof, and in the product state, the bellows 21a is contracted and acts as a strengthening portion. The inner bag 21 can also be used in an aerosol container as shown in FIG. Also in this case, the operation of inserting the valve into the inner bag becomes easy.

The aerosol product 25 in FIG. 5 is a product in which a reinforcing portion is provided on the upper portion of the inner bag 26, and a ring-shaped reinforcing member 27 is fixed on the upper portion of the inner bag 26. Further, a dip tube 28 having a tip extending toward the bottom of the inner bag 26 is provided at the lower end of the housing 13 a of the valve 13. Other configurations are substantially the same as the aerosol product 10 of FIG.
In this case, the main color content A1 is filled below, and the final color content A2 is stacked on top and filled.
Since it is configured in this manner, the aerosol product 25 also discharges the main color content A1 first, discharges the main color content A1, and then discharges the final color content A2. That is, the body part of the inner bag 26 is first deformed by the propellant, and finally the upper part (strengthened part) of the inner bag 26 is deformed. Therefore, similarly to the aerosol product of FIG. 1, the user can recognize that the remaining amount is small when the final color content A2 is discharged.

  In the aerosol product 30 of FIG. 6, the content A is filled between the inner bag 31 and the pressure vessel 32, the propellant B is filled in the inner bag 31, and the lower portion 31a of the inner bag 31 is It is a strengthening part. That is, the aerosol product 30 includes a flexible inner bag 31, a bottomed cylindrical pressure-resistant container 32 that accommodates the inner bag 31, a valve 33 that closes the opening of the inner bag 31 and the pressure-resistant container 32, The final color content A2 filled between the inner bag 31 and the pressure vessel 32 up to the site of the reinforced portion 31a, the main color content A1 filled between the other inner bag 31 and the pressure vessel 32, It consists of the propellant B with which the inner bag 31 is filled. As shown in the inner bag 20b of FIG. 2c, the inner bag 31 has a lower portion 31a that is thicker than other parts, and is composed of a trunk, a bottom, a shoulder, and a neck. The pressure vessel 32 includes a trunk portion, a bottom portion, a shoulder portion, and a neck portion.

  The valve 33 includes a housing 33a, a stem 33b, a stem rubber 33c, a spring 33d, and a cap 33e. The housing 33a has a communication hole 34 that communicates between the inner bag 31 and the pressure vessel 32. Yes. Further, a sealing member 35a for sealing between the inner bag 31 and the pressure vessel 32 and a cylindrical fixing member 36 for pressing and fixing the sealing member 35a with a cap 33e are provided. The valve 33 is fixed by caulking the cap 33e to the neck of the pressure vessel 32. That is, the sealing material 35a, the fixing member 36, and the flange portion 37 of the housing 33a are stacked on the upper ends of the inner bag 31 and the pressure vessel 32, and are closed while being pressed by the cap 33e. Further, a sealing material 35b is provided between the inner bag 31 and the housing 31a.

  Since the aerosol product 30 is configured in this manner, the main color content A1 is also discharged first, and the main color content A1 is discharged, and then the final color content A2 is discharged. As a method for reinforcing the lower portion 31a of the inner bag 31, any of the types shown in FIGS. 2a to 2d may be used depending on the shape of the inner bag.

  The aerosol product 40 in FIG. 7 uses compressed gas as the propellant B, and allows the user to recognize that the remaining amount is small by utilizing the pressure drop phenomenon caused by the use of the aerosol product 40. . Specifically, the form of the discharged material changes as the pressure decreases.

  The inner bag 41 of the aerosol product 40 includes a cylindrical body portion 41a, a reduced diameter portion 41b provided at the lower end thereof, a bottom portion 41c closing the lower end, and a tapered shoulder formed at the upper end of the body portion 41a. It consists of a portion 41d, a cylindrical neck portion 41e formed at the upper end of the shoulder portion 41d, and a flange portion 41f formed at the upper end of the neck portion 41e. The reduced diameter portion 41 b is formed with a communication hole 42 that communicates with the gap between the inner bag 41 and the pressure vessel 12. Further, an elastic ring 43 is provided on the outer periphery of the reduced diameter portion 41b so as to close the communication hole 42. The communication hole 42 and the ring 43 constitute a valve that allows the propellant B to enter the inner bag 41 when the pressure of the propellant B decreases.

  Since it is configured in this way, while the pressure of the propellant B is strong, the ring 43 strongly presses the communication hole 42 and seals the communication hole 42 (see FIG. 7b). On the other hand, when the pressure of the propellant becomes weak, the sealing performance of the communication hole 42 by the ring 43 becomes weak, and the compressed gas which is the propellant enters the inner bag 41 (see FIG. 7c). Thereby, compressed gas melt | dissolves in the contents in an inner bag. Therefore, the user can recognize that the remaining amount of the content is small if the discharged product foams when the aerosol product 40 is used. Note that a foaming agent such as a surfactant may be added to the contents in order to further ensure foaming of the discharged material.

The aerosol product 45 of FIG. 8 includes a protrusion 47 that protrudes downward from the lower end of the housing 46a of the valve 46, and a communication hole 47a is formed on the outer periphery thereof. A ring 43 is provided so as to close the communication hole 47a. The other configuration is substantially the same as the aerosol product 30 of FIG. 4 except that the inner bag 48 does not include a reinforcing portion and there is only one type of content.

  Because of this structure, while the pressure of the propellant is strong, the ring 43 strongly presses the communication hole 47a, seals the communication hole 47a, and when the pressure of the propellant becomes weak, the ring 43 The sealing performance of the communication hole 47a is weakened. Therefore, the compressed gas as the propellant enters the housing 46a, the compressed gas is mixed with the contents, and the contents are foamed. Therefore, the user can recognize that the remaining amount of the content is small if the discharged product has foamed when the aerosol product 45 is used.

The aerosol product 50 shown in FIG. 9a does not show any change in the discharged contents, but the member separates from the inner bag when the remaining amount of the contents decreases. That is, when the aerosol product 50 is shaken in a state where the remaining amount of the content is low, the sound is struck by the separated members.
The aerosol product 50 includes an inner bag 51 having a ring-shaped separation member 52 fixed at the center. Other configurations are substantially the same as the aerosol product 10 of FIG. 1, except that there is only one type of content.
The inner bag 51 is provided with a trunk portion, a bottom portion, a shoulder portion, a neck portion, and a flange portion, similarly to the inner bag 11 of FIG. 2, and is illustrated in that it includes an annular recess 51 a at the center portion of the trunk portion. 2 different from the inner bag 11.

  Since it is configured in this manner, the separation member 52 is firmly held by the recess 51a when the content A is filled in the inner bag 51. On the other hand, when the inner bag 51 is deformed by operating the aerosol product 50 to discharge the contents A, the annular recess 51a cannot hold the separation member 52, and the separation member 52 is separated from the inner bag 51 (FIG. 9b). reference). Thus, since the separation member 52 is released in the pressure resistant container 12, the separation member 52 and the pressure resistant container 12 come into contact with each other by shaking the aerosol product 50, and a sound is generated.

In the aerosol product 50 of FIG. 9a, the separation member 52 is held by the recess 51a. However, the separation member 52 is held in a state where the inner bag is filled with the content A, and the content A is discharged from the inner bag. As long as the separation member 52 is configured to be released after being reduced, an annular protrusion may be formed on the inner bag, or another mechanical structure may be formed. Further, the separating member 52 may be fixed to the inner bag with an adhesive or the like so as to be separated by deformation of the inner bag.
Further, for example, in the double aerosol product in which the inner bag is inflated as shown in FIG. 4 or FIG. 8, a ring-shaped separation member is provided on the outer periphery of the inner bag, and the separation member is cracked and separated by inflating the inner bag. The member may be separated from the inner bag.

The aerosol product 60 in FIGS. 10a and 10b includes a comb-shaped injection member 61 having a plurality of discharge holes 62, and uses compressed gas as a propellant. As the aerosol container 65 composed of a pressure-resistant container, a valve, and an inner bag, a conventionally known double aerosol container is used.
The injection member 61 includes a cylindrical engaging portion 63 that engages with the stem 13b of the valve, and a rectangular comb portion 64 that is provided at the upper end of the engaging portion and has a discharge hole 62 formed therein. And an ejection member passage 61 a that communicates with the discharge hole 62. The engaging portion 63 serves as an introduction hole for the contents.
The engaging part 63 is a part into which the stem 13b is inserted at the lower end, and an engaging part inner passage 63a is formed at the center.

The comb portion 64 is formed with a plurality of discharge holes 62a to 62g arranged at the upper and lower centers of the surface and a plurality of branches 66 arranged vertically on both sides of the discharge holes. The comb portion 64 is formed with a comb-portion passage 64 a that communicates the engaging portion 63 with the respective discharge holes 62. The comb portion inner passage 64a and the engagement portion inner passage 63a of the engagement portion 63 constitute an injection member inner passage 61a.
The respective discharge holes 62a to 62g are formed at equal intervals in the comb inner passage 64a. That is, the distance (resistance value) between each of the discharge holes 62a to 62g and the introduction hole (engagement portion 63) is different. Therefore, when the contents are introduced from the introduction hole (engagement portion 63) and the contents are discharged from the discharge holes 62a to 62g, different forces are required to discharge the contents from the discharge holes 62a to 62g. .

Because of this configuration, when the pressure of the propellant (compressed gas) is greater than a certain value, the content A is ejected from all of the ejection holes 62a to 62g, but the pressure has a certain value. If it falls below, the number of the discharge holes 62 through which the content A is discharged decreases. That is, when the pressure of the propellant (compressed gas) is decreased by using the aerosol product 60, the number of discharge holes 62 for discharging the contents is decreased. In FIG. 10a of the present embodiment, the discharge is not sequentially performed from the upper discharge holes 62a, and in FIG. 10c, the discharge is not sequentially performed from the discharge holes 62a at both ends. Therefore, the remaining amount of the contents of the aerosol product 60 can be confirmed. For example, as shown in FIG. 10a, the surface of the comb portion 64 may be divided into three colors (G (green), Y (yellow), and R (red)) so that the remaining amount can be further understood.
In the embodiment of FIG. 10a, the resistance value for discharging the contents A from each discharge hole is changed depending on the distance from the introduction hole to the discharge hole. However, as shown in FIG. The resistance value may be changed by changing the hole diameter of 62c. Furthermore, the diameter of the passage may be changed, or a resistor may be provided on the passage.

The aerosol product 70 of FIG. 11 is provided with a pressure sensor 72 and a display unit 73 for displaying the value thereof on an injection member 71. This also uses compressed gas as a propellant.
The injection member 71 includes a columnar base 74 and a nozzle 75 protruding outward from the side surface.

  The base 74 includes a stem engaging portion 74a provided at the lower end, a nozzle engaging portion 74b provided on the side surface, and a base inner passage 74c that connects them. The base inner passage 74c extends upward from the stem engaging portion 74a, and is bent substantially vertically (horizontal direction) in the vicinity of the nozzle engaging portion 74b. Therefore, the pressure sensor 72 is attached to the bent top portion 74d that receives the contents flowing upward. Further, on the upper surface of the base 74, there is provided a display unit 73 composed of a lamp configured to display a color that changes depending on the value of the pressure sensor 72.

The nozzle 75 has a cylindrical shape, a base portion is inserted into the nozzle engaging portion 74b, and a nozzle tip 76 is attached to the tip.
Since it is comprised in this way, the content A which flows through the injection member 71 collides with the pressure sensor 72, and the color of the display part 73 changes based on the pressure value. In this embodiment, the remaining amount of content can be confirmed by the color of the display unit 73 using the pressure drop accompanying the decrease in the content. Although a pressure sensor is used here, a flow rate sensor that measures the flow rate of contents may be used.
