JP5616683B2 - Aerosol product with switching function between constant injection and continuous injection - Google Patents

Description

  The present invention relates to an aerosol product having a switching function between quantitative injection and continuous injection.

The aerosol product continuously injects the contents by performing an injection operation. If the injection operation is continued, the aerosol product continues to be injected until the contents disappear. Therefore, the product is used according to the user's intention. On the other hand, a fixed-injection type aerosol product that injects a certain amount of contents in a single operation is also known. In such an aerosol product, even if the injection operation is continued, if a certain amount is injected, the injection stops or becomes a very small amount. For this reason, it is used for a material whose contents are relatively susceptible to the human body or an expensive material.
Furthermore, an aerosol product having both functions of quantitative injection and continuous injection is also known (Patent Document 1). This aerosol product uses a constant amount injection and a continuous injection depending on the amount by which the stem of the aerosol valve is pushed down, and can be selected by the user according to the use situation.

Japanese Patent Laid-Open No. 11-42447

However, in an aerosol product in which the movable distance of the stem is generally set to about 2 to 3 mm, it is difficult for a general consumer to control by the amount of pushing down the stem as in the aerosol product of Patent Document 1. In addition, since the switching is performed only by the user's pushing or subtracting, it is not known which injection specification is used by the non-user. In particular, since the aerosol product of Patent Document 1 seals the hole supplied into the metering chamber at the lower end of the stem, it is necessary to push down the stem completely in order to perform metering injection, and it must be pushed down strongly. It is hard to understand that it is pushing down.
An object of the present invention is to provide an aerosol product capable of reliably switching between a fixed injection and a continuous injection.

The aerosol product of the present invention has an aerosol container composed of a pressure-resistant container and an aerosol valve, an injection member attached to the aerosol container, and an aerosol composition filled in the aerosol container. An introduction hole for introducing the aerosol composition in the pressure vessel, a valve passage communicating from the introduction hole to the stem hole , a cylindrical housing portion provided in the valve passage and having an opening on the downstream side thereof; and a movable valve which is movably housed in the housing by operation before injecting operating the injection member comprises an injection amount switching mechanism capable of switching the injection amount, the injection quantity by performs an operation to jet operating the injection amount switching mechanism so as to increase, the movable valve is the opening of the downstream opening of the housing part Closed so that the product is close or shrink, aerosol composition is quantified injected with a large amount of the injection amount by the injector operation by operating the injection amount switching mechanism so that the injection amount is reduced, valve passage Since the flow rate of the aerosol composition is small, the movable valve floats in the housing part without closing the opening on the downstream side of the housing part, and the aerosol composition is continuously injected with a small amount of injection . .
The movable valve as used in the present invention refers to a valve that moves by a pressure difference when a stem hole is opened and the inside of an aerosol container is communicated with the atmosphere like a ball. In addition, the injection amount refers to the amount of the aerosol composition injected from the injection holes per unit time, and when a plurality of injection holes are provided, the total amount of the aerosol composition injected from all of the injection holes. Say.
Further, as an injection amount switching mechanism capable of switching the injection amount, for example, switching of passages having different passage diameters in the injection member, switching of passages having different passage lengths in the injection member, switching of passages in the stem having different stem hole diameters. And switching the number of stem holes.

  It is preferable that the aerosol product has two injection passages that are switchable and have different resistances. In particular, the injection member includes a base member and a switching member that is connected to the base member and includes two injection passages, and communicates with the base member by rotating the switching member with respect to the base member. What can select the injection path to perform is preferable.

In such an aerosol product, the aerosol valve has a stem that can switch the injection amount according to the push-down amount, and the operation of regulating the stem push-down amount before the injection member performs the injection operation is performed. It may be provided with a means for enabling.
Furthermore, the stem of the aerosol valve may be a tilt-type stem, which can be switched between two injection amounts depending on whether the stem is pushed straight down or tilted, and the injection member can regulate the inclination of the stem.

In the aerosol product of the present invention, when the injection amount switching mechanism is operated so as to increase the injection amount, and the injection operation is performed, the flow rate of the aerosol composition flowing through the valve passage is increased, and an opening having an opening on the downstream side is accommodated. The movable valve accommodated in the part is operated, and the valve passage (opening on the downstream side of the accommodation part) is closed or the diameter of the passage is reduced. Therefore , the aerosol composition can be quantitatively injected with a large amount of injection . That is, when the movable valve closes the valve passage (opening on the downstream side of the accommodating portion) , the injection stops after the fixed amount injection. Even when the movable valve reduces the diameter of the passage (opening on the downstream side of the housing) , after a certain amount of aerosol composition is injected, the aerosol composition is continuously injected with a small amount of injection, and the injection amount changes significantly. Therefore, the user can recognize that a fixed amount of the aerosol composition has been injected, and can perform a substantially fixed amount injection.
On the other hand, by operating the injection amount switching mechanism so that the amount of injection is reduced, if injecting operation, without closing the downstream opening of the flow rate small fry, the movable valve housing portion of the aerosol composition through the valve passages The movable valve does not perform its function. Therefore, continuous injection is performed with the small injection amount. As described above, according to the present invention, it is possible to surely select the quantitative injection or continuous injection of the aerosol composition by operating the injection member before performing the injection operation.
Moreover, since the fixed quantity injection of the aerosol product of the present invention has a large injection amount, it can be injected vigorously over a wide area (for example, flying insects). On the other hand, since continuous injection has a small injection amount, it can be accurately injected into a narrow area (such as a gap in furniture). Furthermore, in the case of an aerosol composition containing a resin such as a hair spray, even if the resin dries at the injection hole to form a film and clogs, it breaks the resin film by quantitative injection that injects a large amount of contents in a short time. The clogging can also be released.

  In the aerosol product of the present invention, when the injection member includes two injection passages that are switchable and have different resistances, the structure of the injection amount switching mechanism is simple and easy to manufacture. The injection member includes a base member and a switching member connected to the base member and including at least two injection passages, and communicates with the base member by rotating the switching member with respect to the base member. When the injection passage can be selected, the switching of the injection passage of the injection member is simple and reliable.

The aerosol product according to the present invention includes a valve that can be switched between two injection amounts according to the amount by which the stem is pushed down, and has an injection member having means for controlling the amount by which the stem is pushed down before the injection operation. Even if it is equipped with, the operation is simple and reliable.
Furthermore, the valve stem is a tilt-type stem that can be switched between two injection amounts, when the stem is pushed straight down and when it is tilted, and can be controlled by the user even when the stem tilt can be controlled. Is simple and reliable.

  The aerosol product 10 in FIG. 1 includes an aerosol container 11 having a fixed-quantity injection mechanism and an injection member 12 having an injection amount switching mechanism attached to a valve of the aerosol container. The aerosol container 11 is filled with an aerosol composition A composed of the contents and a propellant, whereby an aerosol product is obtained.

  The aerosol container 11 includes a pressure resistant container 16 made of metal such as aluminum or tinplate, and an aerosol valve 17 (hereinafter referred to as a valve) attached to the opening. The pressure vessel 16 includes a cylindrical body portion 16a, a bottom portion 16b that closes the lower end of the body portion, a tapered shoulder portion 16c formed at the upper end thereof, and a bead portion 16d provided at the upper end of the shoulder portion. It is an integral molded product. However, other containers such as a container in which an upper end is extended in a cylindrical shape without providing a bead portion and an annular protrusion protruding inwardly in a cylindrical lower portion may be used.

  As shown in FIG. 2, the valve 17 has a quantitative injection mechanism. As shown in FIG. 2, the tubular housing 21, the stem 22 accommodated in the housing so as to be movable up and down, and the stem 22 are always urged upward. Spring 23, a stem rubber 24 that closes the stem hole of the stem 22, a mounting cup 25 that covers the upper portion of the housing 21 and is fixed to the pressure-resistant container 16, a ball receiving portion 26 attached to the lower end of the housing, and the inside of the receiving portion And a dip tube 28 attached to the lower end of the accommodating portion.

The housing 21 has an upper end opened, and an upper cylinder part 21a for accommodating the stem 22, a lower end opened, a lower cylinder part 21b inserted into the ball accommodating part 26, and a partition wall 21c separating them. The upper cylinder part 21a and the lower cylinder part 21b communicate with each other through a communication hole 21d formed at the center of the partition wall 21c. Further, a notch 21e is formed in a part of the lower end of the lower cylinder portion 21b.
The stem 22 has a bottomed cylindrical shape, is open at the upper end, and has a stem hole 22a on the side surface.
The spring 23 is provided between the lower end of the stem 22 and the partition wall 21 c of the housing 21.
The stem rubber 24 has a ring shape that closes the stem hole 22 a and is sandwiched between the upper end opening of the housing 21 and the mounting cup 25.

The mounting cup 25 includes a mounting portion 25a fixed to the bead portion, a central housing holding portion 25b, and a connecting portion 25c that connects the mounting portion 25a and the housing holding portion 25b. Is formed with a central hole that allows the stem 22 to protrude. A rising wall 25d is formed in the center hole so as to support the vertical movement of the stem 22. Further, a sealing material 25e is provided between the mount portion 25a and the bead portion.
The ball housing portion 26 includes a housing mounting portion 26a that receives the lower tube portion 21b of the housing, a housing portion main body 26b that houses the ball 27, and a cylindrical connecting portion 26c to which the dip tube 28 is connected. The diameter of the housing main body 26 b is configured to be larger than the ball 27. The diameters of the lower cylinder portion 21b and the connecting portion 26c connected to the housing mounting portion 26a are smaller than those of the ball 27, thereby holding the ball 27 movably up and down in the ball accommodating portion 26.

  The fixed-quantity injection valve 17 configured as described above pushes down the stem 22, opens the stem hole 22a from the stem rubber 24, and communicates the inside of the valve 17 and the atmosphere, whereby the aerosol composition A in the aerosol container is communicated. Is introduced from the opening (introduction hole) 28a of the dip tube 28, and at the same time, the ball 27 in the housing main body 26b is pushed up by the aerosol composition. That is, the ball 27 closes the lower end opening of the lower cylindrical portion 21b of the housing leaving a notch 21e (imaginary line in FIG. 2). Thereby, the aerosol composition (quantitative aerosol composition) in the housing 21 is ejected from the ball housing portion 26 at a time (quantitative ejection state). Thereafter, the aerosol composition A is introduced into the housing 21 through the notch 21e. However, the amount of the aerosol composition is very small, and the injection amount is also very small (a micro injection state). Therefore, it can be recognized that the transition from the quantitative injection state to the micro injection state is made due to the difference in the injection amount, and if the injection operation is stopped when the micro injection occurs, the fixed amount aerosol composition is injected.

  On the other hand, when the injection operation is stopped and the stem 22 is lifted upward by the spring 23, the inside of the housing 21 is hermetically sealed while leaving a notch 21e. When the aerosol composition is introduced into the housing 21 from the notch 21e, the ball 27 descends in the ball housing portion 26 by its own weight. As a result, repeated quantitative injection can be performed.

Next, the injection member 12 of FIG. 3 includes an injection amount switching mechanism, a guard 31 attached to the mount portion 25a of the valve 17, a base member 32 connected to the stem 22 of the valve 17, and its It consists of the switching cap 33 attached to a base member.
The guard 31 includes a ring-shaped attachment portion 36 and two grooves 37 formed on the inner surface and extending in the vertical direction. The mounting portion 36 has an annular recess having a lower end formed of an inner wall 36a, an outer wall 36b, and a top surface 36c connecting them, and an annular locking portion 36d protruding inwardly on the inner surface of the lower end of the outer wall. Is formed. The annular recess covers the mount portion 25a, and the locking portion 36d engages with the mount portion 25a. The groove 37 is formed so as to face the inner surface of the mounting portion 36, and prevents rotation of the base member 32, which will be described later, around the stem.

The base member 32 includes a disc-shaped bottom portion 41 and a cylindrical passage portion 42 formed upward in the center thereof. The center of the back surface of the bottom portion 41 is a stem engaging portion 41 a that communicates with the inside of the passage portion 42. A slit 43 extending in the vertical direction is formed at a part of the upper end of the passage portion 42. Further, two outwardly protruding protrusions 44 are formed on the outer periphery of the bottom portion 41 so as to be separated by 180 degrees.
The switching cap 33 has a cylindrical shape having an upper bottom 33a, and includes an injection hole 46 formed on a side surface and a cylindrical base member connecting portion 47 extending downward from the center of the upper bottom 33a. The passage portion 42 and the injection hole 46 are communicated with each other by two upper and lower communication passages 48a and 48b extending horizontally through the base member connecting portion. The injection hole 46 is configured by inserting an injection tip. The front end (injection hole side) of the communication path 48a communicates with the injection hole 46 along the inner surface of the injection tip. Moreover, you may provide the mechanical breakup mechanism provided with the groove | channel formed in the spiral shape in the injection tip inner surface.

  The injection member 12 connects the base member 32 to the guard 31 so as to engage with the protrusions 44 of the base member 32 in the groove 37 of the guard 31, and the passage portion 42 of the base member 32 is switched. The switching cap 33 is rotatably connected to the base member 32 so as to be inserted into the base member connecting portion 47 of the cap 33. At this time, the upper end of the passage portion 42 is configured to be between the upper and lower communication passages 48a and 48b of the switching cap (configured so that a gap is formed between the passage portion 42 and the upper bottom 33a. The lower end of the slit 43 is configured to be lower than the lower communication path 48b.

  Since the injection member 12 is configured in this way, the switching cap 33 is connected to the base member 32 so that the slit 43 of the passage portion 42 of the base member 32 and the communication passage 48b below the switching cap 33 communicate directly with each other. By sliding and rotating (see FIG. 3b), the passage portion 42 of the base member 32 and the injection hole 46 of the switching cap 33 communicate with each other through the upper and lower communication passages 48a and 48b (large injection amount state, large flow rate, passage) Small resistance). On the other hand, by rotating the switching cap 33 with respect to the base member 32 so that the communication passage 48b under the switching cap 33 is closed by the passage portion 42 (upper cylindrical portion) of the base member 32 (see FIG. 3a), The communication passage 42 of the member 12 and the injection hole 46 of the switching cap communicate with each other only through the upper communication passage 48a (small injection amount state, low flow rate, high passage resistance). At this time, since the protrusion 44 of the base member 32 is engaged with the groove 37 of the guard 31, the base member 32 does not follow the rotation of the switching cap 33.

In this switching operation, a click feeling may be given simultaneously with the switching so that the user can recognize whether the position of the switching cap 33 is in the large injection amount state or the small injection amount state. Thereby, the user can switch more reliably. Further, the switching cap 33 may be configured to be switched within 90 degrees with respect to the base member 32, and the switching cap 33 may be configured to be unable to rotate more than 90 degrees with respect to the base member 32. Thereby, the operation of the switching cap 33 is easier.
On the other hand, the injection operation of the injection member 12 is performed by pressing the upper bottom of the switching cap 33 downward and pressing the base member 32 and the switching cap 33 downward with respect to the guard 31. As a result, the stem 22 engaged with the base member 32 is lowered and the valve 17 is opened.

The aerosol product 10 in which the aerosol container 11 having such a quantitative injection function and the injection member 12 having the injection amount switching mechanism are combined so that the injection amount of the injection member 12 is large (the passage resistance is small). When the injection member 12 is operated to perform the injection operation, the flow rate of the aerosol composition flowing through the housing main body 26b is sufficiently large, and the ball 27 closes the opening of the lower cylindrical portion 21b of the housing. Therefore, a fixed amount of the aerosol composition A in the valve 17 is injected with a large injection amount, and then a minute injection state is obtained. And the user can recognize that the fixed amount aerosol composition A was injected by the difference in the injection amount.
On the other hand, when performing the injection operation by operating the injection member 12 so that the injection amount of the injection member 12 is small (the passage resistance is large), the flow rate of the aerosol composition A introduced from the pressure-resistant container 16 to the valve 17 is small. (The flow rate of the aerosol composition flowing in the housing portion main body 26b is reduced), so that the ball 27 floats in the housing portion main body 26b without closing the opening of the lower cylindrical portion 21b of the housing as shown in FIG. . That is, the aerosol composition A is injected with a small injection amount without exhibiting the quantitative injection function of the valve 17. Therefore, the aerosol composition A is continuously injected with a small injection amount. As described above, the aerosol product 10 according to the present invention can be switched between the fixed injection state and the continuous injection state only by slidingly rotating the switching cap of the injection member 12, and thus the operation is reliable and simple.

  In the aerosol product of FIG. 5, the injection member 12 is a nozzle type, and the pressure-resistant container 16 of the aerosol container 11 is a three-piece can. The pressure vessel 16 is a known three-piece can provided with a metal part 19 connected to the upper end (clamping part 19a) of the body part 16a by double winding. Other configurations are substantially the same as the aerosol product 10 of FIG.

The injection member 50 includes a base member 51 attached to the stem of the valve, a nozzle 52 coupled to the base member, and a cover 53 attached to the aerosol container so as to cover the base member 51.
The base member 51 has a cylindrical shape bent at a right angle, and engages with the stem 22 at the lower end and engages with the nozzle 52 at the tip.

The nozzle 52 includes a connecting member 54 that is engaged with the base member 51 and a nozzle body 55 that is attached to the connecting member.
The connecting member 54 has a spherical inner space, and the inner space communicates with the outside through a slit 54a.
The nozzle body 55 includes a hemispherical or semi-cylindrical base end portion 56 and a nozzle portion 57 extending from the base end portion to one side.
The base end portion 56 is fitted into the internal space of the connecting member 54 and is configured to be able to rotate 90 degrees within the connecting member 54. The base end portion 56 passes through the base end portion 56 and is perpendicular to the nozzle portion 57, and the second passage passes through the base end portion 56 and is parallel to the nozzle portion 57. 58b. The first passage 58 a and the second passage 58 b are independent of each other, and the second passage 58 b is configured so as to circumvent a ring on a plane parallel to the nozzle portion 57.
The nozzle part 57 is cylindrical and communicates with the second passage 58b. A cylindrical injection nozzle 59 is further connected to the tip of the nozzle portion 57 according to the purpose of use. The diameter of the first passage 58a (large injection amount, small passage resistance) is larger than that of the second passage 58b (small injection amount, large passage resistance). However, if the spray nozzle 59 is long and the resistance is increased even if the diameter is the same, the spray amount of the aerosol composition passing through each passage is different, and the spray amount switching mechanism is formed.

  The cover 53 is connected by a mounting portion 62 to be mounted on the winding portion 19a of the aerosol container, a cover portion 63 that covers substantially the entire base member 51, a rear upper end of the mounting portion and a hinge portion 64, and pushes down the base member 52. And an operation unit 65 for this purpose.

The injection member 50 is rotated so that the nozzle body 55 faces downward, so that the base member 51 communicates with the first passage 58a having a large injection amount (low resistance) and quantitatively injects (FIG. 5a). . On the other hand, by rotating the nozzle body 55 so as to face the horizontal, the base member 51 communicates with the second passage 58b with a small injection amount (high resistance) and continuously injects (FIG. 5b).
That is, when the injection member 50 is attached to the aerosol container having the valve of FIG. 2, the switching between the constant injection state and the continuous injection state simply rotates the nozzle body 55 of the injection member 50, and the aerosol of FIG. As with the product 10, it can be done reliably and easily.

  A valve 70 in FIG. 6 is an alternative to the aerosol product valve 17 in FIG. 1, and is a valve having a quantitative injection mechanism that exhibits a constant injection state and an injection stop state. Specifically, in the valve 17 of FIG. 2, a notch 21e is not formed at the lower end of the lower cylindrical portion 21b of the housing 21, and a spring 71 that constantly urges the ball 27 downward is provided in the ball accommodating portion 26. It is what you have. The other configuration is substantially the same as the valve 17 of FIG.

The constant injection valve 70 configured in this manner injects the aerosol composition in the housing 21 at a time (quantitative injection state) by performing an injection operation, that is, pushing down the stem 22. At the same time, the ball 27 is pushed upward by the aerosol composition A introduced from the opening of the dip tube 28 to close the opening of the lower cylindrical portion 21b. At this time, the valve 70 is not provided with a notch like the valve 17 in FIG. 2, and therefore the housing 21 and the pressure-resistant container 16 are blocked. Therefore, after the aerosol composition in the housing 21 is injected, injection stops once (injection stop state).
Next, when the injection operation is stopped, the spring 71 pushes the ball 27 back downward, and the housing 21 and the pressure vessel 16 communicate with each other again. Thereby, the aerosol composition is refilled in the housing 21, and it becomes possible to perform quantitative injection repeatedly.

  In the aerosol product in which the aerosol container provided with the valve 70 and the injection member 12 of FIG. 3 or the injection member 50 of FIG. 5 provided with the injection amount switching mechanism are combined, the injection member 12 is operated so that the injection amount becomes large. Then, when the injection operation is performed, the ball 27 closes the opening of the lower housing cylinder portion 21b and performs constant injection. On the other hand, when the injection operation is performed by operating the injection member 12 so that the injection amount becomes small, the aerosol composition A introduced into the valve 70 from the pressure-resistant container 16 becomes small, so the pressure (flow rate) of the aerosol composition A And the spring 71 are balanced, and the ball 27 floats in the housing main body 26b without closing the opening of the lower cylinder portion 21b. Therefore, the aerosol composition A continues to be injected without exhibiting the quantitative injection function of the valve 17.

  The valve 75 in FIG. 7 is also an alternative to the valve in FIG. 2, and a plate-like piston 76 is used instead of the ball 27 of the valve in FIG. 2, and a spring that constantly biases the piston 76 downward is used. 71 is provided in the ball housing portion 26. The piston 76 has an upper bottom cylindrical shape. A communication hole 77 having a small cross-sectional area is formed on the upper base, and a side communication hole 78 having a cross-sectional area larger than the communication hole 77 is formed on a side surface. ing. The spring 71 constantly biases the piston 76 downward, and at the same time maintains the posture of the piston 76.

Since it is configured in this manner, the passage of the aerosol composition A is only the communication hole 77 when the piston 76 closes the lower cylindrical portion 21b of the housing 21, and a minute injection state is obtained. Therefore, the user can recognize that the predetermined aerosol composition A has been injected due to the change in the injection amount. Other configurations are the same as those of the valve 17 of FIG.
Therefore, by attaching the injection member 12 of FIG. 3 or the injection member 50 of FIG. 5 provided with the injection amount switching mechanism to the aerosol container provided with the valve 75, switching between the fixed injection state and the continuous injection state is performed. Can be changed.

  The aerosol product 80 in FIG. 8 differs from the aerosol product 10 in FIG. 1 in that an injection amount switching mechanism is configured by a valve 81 and an injection member 83. That is, the injection amount is switched according to the movement amount (downward movement amount) of the stem 82 of the valve 81, and the movement range of the stem is restricted by the injection member 83.

The valve 81 includes two stem holes 82a and 82b in which stems 82 are formed side by side. The other configuration is substantially the same as the valve 17 of FIG.
Since it is configured in this manner, by pushing down the stem 82 so that both the stem holes 82a and 82b are opened, the injection amount of the aerosol composition becomes large (see FIG. 9a), and only the lower stem hole 82b. By pushing down the stem 82 so as to be opened, the spray amount of the aerosol composition is reduced (see FIG. 9b).

On the other hand, the injection member 83 includes a guard 86 attached to the valve mount 25a and a push button 87 connected to the stem 82 of the valve.
The guard 86 has a ring-shaped mounting portion 86a, a pair of long grooves 86b formed on the inner surface and extending in the vertical direction, and a vertical groove formed on the inner surface, and extends in the vertical direction. And a pair of short grooves 86c. The attachment portion 86a is substantially the same as the attachment portion 36 of FIG. 3, and includes an inner wall, an outer wall, a top surface, and a locking portion. The pair of long grooves 86b and the pair of short grooves 86c are formed so as to be 90 degrees from each other, as shown in FIG. 8b. However, the angle is not particularly limited.
The push button 87 has a columnar shape, and includes a stem engaging portion 87a provided at the center of the lower end, an injection hole 87b provided on a side surface, and a button passage 87c that communicates them. A pair of flanges 87d projecting outward is formed on the lower side surface.

  Because of this configuration, the push button 87 is inserted into the guard 86 only at a position where the flange 87d is along the long groove 86b or the short groove 86c (see FIG. 8b). In other words, when the flange 87d is positioned in the long groove 86b, the push button 87 can be pushed down deeply in the guard 86 (see FIG. 9a). Conversely, when the flange 87d is positioned in the short groove 86c, the push button 87 is Can only be pushed down shallowly (see FIG. 9b).

  Since the aerosol product 80 includes the valve 81 and the injection member 83, the push button 87 is disposed so that the flange 87d is positioned in the long groove 86b, and the push button 87 is pushed down so that the two stem holes 82a, 82b are formed. It is opened and the injection amount of the aerosol composition becomes large, the quantitative injection mechanism of the valve 81 functions, and the aerosol product 80 enters the fixed injection state (see FIG. 9a). On the other hand, by disposing the push button 87 so that the flange 87d is positioned in the short groove 86c and pushing down the push button 87, only the lower stem hole 82b is opened, and the injection amount of the aerosol composition is reduced. The fixed quantity injection mechanism does not function, and a continuous injection state is set (see FIG. 9b).

  The aerosol product 90 shown in FIG. 10 is different from the aerosol product 10 shown in FIG. 1 in that the injection amount switching mechanism is configured by the valve 91 and the injection member 93. In the aerosol product 90, the injection amount changes depending on the operation direction of the push button, and when the push button of the injection member is pushed downward, it becomes a fixed injection, and when the push button is tilted, it becomes a continuous injection.

  The valve 91 of the aerosol product 90 is a tilt type valve, and the stem 94 is supported in the housing 21 so as to be tiltable. Specifically, the stem 94 includes a cylindrical stem upper portion 94a, a columnar stem lower portion 94b, and an annular flange portion 94c provided therebetween and projecting outward. The stem upper portion 94a is formed with two stem holes 95a, 95b arranged vertically. The columnar stem lower portion 94b is smaller than the inner circle of the columnar space 21x in the housing 21 and can be tilted in the housing. However, as long as the cross-sectional shape of the stem lower portion 94b inserted into the housing 21 has an outer circle smaller than the inner circle of the cross-sectional shape in the housing 21, the shape is not particularly limited. The lower surface of the flange portion 94c receives the spring 23, and the upper surface is in contact with the stem rubber 24 for sealing.

Since it is configured in this manner, when the stem 94 is pushed straight down deeply, the two stem holes 95a and 95b are opened, the injection amount is increased, and a constant injection state is established (see FIG. 11a). On the other hand, when the stem 94 is tilted in either direction, only the lower stem hole 95b is opened, and a continuous injection state is achieved with a small injection amount (see FIG. 11b).

The injection member 93 includes a guard 96 attached to the valve mount 25 a and a push button 97 connected to the valve stem 82.
The guard 96 has a ring-shaped mounting portion 86a similar to that in FIG. 8 and a single groove 96a formed on the inner surface thereof and extending in the vertical direction (see FIG. 10b).
The push button 97 has a columnar shape, and has a stem engaging portion, an injection hole, and a passage in the button similarly to the push button 83 in FIG. One is formed.
With this configuration, when the push button 97 is arranged so that the protrusion 97a is positioned other than the groove, the protrusion 97a is supported on the inner surface of the mounting portion 86a, and the push button 97 can be pushed down only downward. Yes (see FIG. 11a). On the other hand, when the push button 97 is arranged so that the protrusion 97a is positioned in the groove 96a, the push button 97 can be inclined toward the groove 96a, and only the stem hole 95b on the flange side is opened (see FIG. 11b). .

  That is, since the aerosol product 90 includes the valve 91 and the injection member 93, the push button 97 is disposed so that the protrusion 97 a is not positioned in the groove 96 a, and the push button 97 is pushed down, thereby the two stem holes 95 a, b is opened, the injection amount increases, the quantitative injection mechanism of the valve 91 functions, and the aerosol product 90 enters the constant injection state (see FIG. 11a). On the other hand, the push button 97 is arranged so that the protrusion 97a is positioned in the groove 96a, and the push button 97 is tilted in the direction of the groove 96a, so that only the flange-side stem hole 95b is opened and the injection amount is reduced. The fixed quantity injection mechanism does not function, and a continuous injection state is set (see FIG. 11b). In this embodiment, a plurality of protrusions 97a may be provided. In that case, the same number of grooves 96a are provided.

  The injection member 100 of FIG. 12 adjusts the injection amount with a filter, and includes a stem engagement portion 101, an injection hole 102, and a communication path 103 that communicates them. In addition, a slit 104 is provided from the upper end so as to close the communication path 103. A filter 105 (FIG. 12b) having holes 106a and 106b having different diameters is inserted into the slit 104, and the filter 105 is slid so that the holes 106a and 106b and the communication path 103 are aligned with each other. It is to switch. A plurality of filters 105 may be inserted to switch the injection amount.

  In the embodiments so far, the injection amount is switched using one injection member, but the injection amount is changed by alternately replacing injection members having different injection amounts (for example, injection members having different injection hole diameters). You may switch and select fixed injection and continuous injection.
