[Prior art]

 Japanese Patent Publication No. 62-41074 discloses an aerosol container having a flow rate control valve having the above-mentioned function. According to the flow control valve, the passage of the contents of the aerosol container is closed when the stem is in the initial position, and the pushing operation of the stem from the initial position causes the passage to be opened. When the stem is pushed into the first pushing area where the pushing amount from the initial position is small, the amount of contents passing through the passage is suppressed to a small amount, and the stem is pushed into the second pushing region where the pushing amount from the initial position is large. It has the function of increasing the amount of contents passing through the passage when is pushed. Therefore, when the spray nozzle attached to the stem is pushed in with the fingers of the hand, when the stem is pushed into the first pushing area, the amount of sprayed contents is reduced, and the stem is put into the second pushing area. When pushed in, the amount of sprayed contents increases.

[Problems to be solved by the device]

 The above-mentioned spray nozzle does not have a means to accurately determine the pressing width in two steps when pressing it with the fingers of the hand, so when it is necessary to suppress the spray amount to a small amount or to increase the spray amount. The user cannot easily determine how much the spray nozzle should be pushed into. Therefore, the user can adjust the initial width of the stem of the flow control valve by adjusting the width of the spray nozzle to increase or decrease while adjusting the amount of contents actually sprayed from the spray nozzle. It was inevitable that the amount of spray from was adjusted to the above-mentioned first or second indentation region to suppress or increase the atomization amount.

However, in the case where the spray amount is adjusted in two steps by manually adjusting the pushing width of the spray nozzle while determining the amount of contents to be actually sprayed, the manual adjustment is often unsuccessful. When it is desired to keep it low, the spray amount becomes unnecessarily large, and when it is desired to increase the spray amount, a sufficient amount is not sprayed. In such a case, for example, if the content is paint, an unnecessarily large amount of paint is sprayed onto the painted surface, or the paint is not sufficiently sprayed onto the painted surface. It becomes impossible to finish it well.

The present invention has been made in view of the above circumstances. That is, according to the present invention, the pushing amount from the initial position of the stem of the spray amount control valve provided in the aerosol container does not depend on the first pushing region which is a small range and the second pushing region which is a large range. It is an object of the present invention to provide a spray amount control nozzle for an aerosol container that can be accurately adjusted to

Further, in the nozzle body 1, only the lower part of the front surface is connected to the mounting portion 2, and the connecting portion is formed as a thin first-formed hinge portion 14 having elasticity, whereas the mounting portion is formed. An opening 23 is formed on the second side to allow the nozzle body 1 to swing up and down about the first molding hinge portion 14. Therefore, in the nozzle body 1, when the pushing operation portion (described later) 15 is pushed with the fingers of the hand, the pushing operation along the pushing direction of the stem 7 described later with the first molding hinge portion 14 as the center is performed. It is possible, and by relieving such a pushing force, the elastic restoring force of the first molding hinge portion 14 causes the backward movement to the original position.

Further, the nozzle body 1 is provided with a pushing operation portion 15. Since the push-in operation portion 15 in the illustrated example is formed by a projecting piece protruding rearward from the rear surface portion of the nozzle body, the distance between the first molding hinge portion 14 and the push-in operation portion 15 is long. Has been secured. Therefore, due to the "lever principle", a small force is required when pushing the nozzle body 1 around the first molding hinge portion 14 with the fingers of the hand. In addition, a space S is formed between the pushing operation portion 15 formed by the protrusion and the flange portion 21 of the mounting portion 2. The vertical width of the space S is narrowed by the pushing operation of the nozzle body 1 and widened by the backward movement of the nozzle body 1.

The possible width H1 is restricted to a small width. Further, the movable piece 3 in the operating posture is pulled outward to release the fitting between the protrusion 27 and the recess 31, and the movable piece 3 is laid down to the outside of the space S as shown in FIGS. 3 and 4. When the retracted posture is set to the retracted position, the movable piece 3 does not control the pushable width of the nozzle body 1, so the pushable width H2 (FIG. 4) of the nozzle body 1 corresponds to the entire vertical width of the space S. Come to do. Here, the projection 27 and the recess 31 described above constitute the posture holding mechanism 4 provided between the movable piece 3 and the mounting portion 2.

Next, an example of the flow rate control valve (hereinafter referred to as “valve”) 5 provided in the container B will be briefly described with reference to FIGS. 14 to 16.

The valve 5 has a housing 6 fixed to the mountain cup 110 of the container B, and a gasket 62 is held at an upper end portion 61 of the housing 6. The bottom wall 63 of the housing 6 is provided with a valve hole 64, a valve seat 65, and a connection port 66, and the connection port 66 is connected with a dip tube 67 as shown in FIG.

The stem 7 is inserted into the hole 68 of the gasket 62, the neck portion 71 of the stem 7 having a small diameter corresponds to the hole portion 68, and the large diameter portion 72 below the neck portion 71 is in the axial direction. It is loosely fitted in the housing 6 so as to be displaceable in the direction X (see FIG. 14), and a protruding portion 73 above the neck portion 71 projects upward from the opening of the mountain cup 110. The stem 7 is formed with a stem hole 74 that opens at the outer peripheral surface of the neck portion 71 and the upper end surface of the protruding portion 73, and the opening of the stem hole 74 located on the outer peripheral surface of the neck portion 71 is When the stem 4 is pushed in or returned, it is brought into contact with or separated from the hole 68 of the gasket 62. The stem hole 74 functions as a passage for the contents of the aerosol container.

The large-diameter portion 72 of the stem 7 is provided with a recessed portion 75, and the upper wall surface of the recessed portion 75 serves as a pressing contact portion 76, while the lower end inner periphery of the recessed portion 75 is formed. A pull-up claw portion 77 is provided in the section. The head portion 81 of the valve rod 8 which is inserted through the valve hole 64 is inserted into the recessed portion 75 of the stem 7, and the upper end surface thereof serves as a receiving portion 82 corresponding to the contact portion 76. At the same time, the lower end stepped portion is an engaging portion 83 corresponding to the pawl portion 77. The head portion 81 of the valve rod 8 is held so as to be displaceable in the axial direction X between the contact portion 76 and the claw portion 77. The valve rod 8 has a communication passage 84 and a valve portion 85, and is held by a valve rod holding body 86 provided in the housing 1. The valve rod holder 86 is made of rubber or a flexible synthetic resin, and holds the valve rod 8 by frictional resistance when the hole 87 provided in the center of the valve rod holder 86 contacts the outer peripheral surface of the valve rod 8. When the valve rod 8 receives a force in the axial direction X, it has a property of allowing the valve rod 8 to slide due to the force. A cutout 88 is provided in the hole 87 of the valve rod holder 86, and the cutout 88 always communicates the valve hole 64 with the inner space of the housing 6.

A spring body 9 composed of a coil spring is interposed between the valve rod holding body 86 and the stem 7, and the spring force of the spring body 9 causes the stem 7 to always move upward toward the initial position. Being energized.

In the valve A configured as described above, in the normal state, the stem 7 is located at the initial position shown in FIG. 14 by the force of the spring body 9, and the stem hole 74 is closed by the gasket 62. Has been. When the stem 7 is pushed in from the initial position as shown by arrows P1 and P2 in FIGS. 15 and 16, the gasket 62 is flexibly deformed as the stem 7 is pushed in and the stem hole 74 is opened.

FIG. 15 shows a state in which the stem 7 is pushed to a position where the contact portion 76 of the stem 7 comes into contact with the receiving portion 82 of the valve rod 8. The amount of pushing of the stem 7 from the initial position at this time is small, and the range of such a small pushing amount from the initial position is the first pushing region, and the first pushing region is represented by reference symbol S1. If the pushing amount of the stem 7 is within the range of the first pushing region S1, the stem hole 74 is opened, and the stem hole 74 is communicated with the communication passage 84 of the valve rod 8 through the internal space of the housing 6. Therefore, the liquid content contained in the container B shown in FIG. 1 rises in the dip tube 67 under the pressure of the gas sealed in the vapor phase portion thereof, and the arrow a in FIG. As described above, after entering the inner space of the housing 1 only through the communication passage 84, the gas flows out through the stem hole 74 as indicated by an arrow b.

FIG. 16 shows a state in which the contact portion 76 of the stem 7 is further pushed in after hitting the receiving portion 82 of the valve rod 8. At that time, the pushing amount of the stem 7 from the initial position is large. The range in which the pushing amount is large from the initial position is the second pushing region, and the second pushing region is represented by reference symbol S2. As can be seen in the figure, the first pushing area S1 and the second pushing area S2 are continuous. If the pushing amount of the stem 7 is within the range of the second pushing region S2, the valve rod 8 is pushed down together with the stem 7, so that the valve portion 85 is separated from the valve seat 65 and the valve hole 64 is opened. As a result, both the communication passage 84 and the valve hole 64 communicate with the inner space of the housing 6, so that the liquid content of the container B shown in FIG. As shown in a and c, it passes through the communication passage 84, the valve hole 64 and the notch 88 of the valve rod holding body 86 into the internal space of the housing 6, and further flows out through the stem hole 74 as indicated by arrow b. . Therefore, when the pushing amount of the stem 7 from the initial position is within the range of the second pushing region S2, the amount of the liquid content flowing out through the stem hole 74 more than in the case described in FIG. Will increase.

When the pushing force on the stem 7 is released, the stem 7 returns to the initial position shown in FIG. 14 by the force of the spring body 9, so that the gasket 62 returns to its original shape and the stem hole 74 is closed. Further, the valve rod 8 is pulled up with the return of the stem 7 to the initial position, and the valve portion 85 hits the valve seat 65 to close the valve hole 64.

Next, as can be seen from FIG. 1 and FIG. 2, the nozzle A should be mounted by fitting the mounting portion 2 thereof into the mouth portion 100 provided in the mount cup 110 of the container B.

Further, in the nozzle A of the illustrated example, as shown in FIG. 5, when the movable piece 3 is in the operating posture, the nozzle main body 1 has a width corresponding to the pushable width H1 of the nozzle body 1. When 1 is pushed in, the relationship between the two is determined so that the pushing amount from the initial position of the stem 7 which is pushed together with the nozzle body 1 is within the above-mentioned first pushing area S1. That is, the relationship of H1 <S1 or H1 = S1 is established. Further, when the nozzle body 1 is pushed in by a width corresponding to the width H2 of the nozzle body 1 that can be pushed in when the movable piece is in the retracted position as shown in FIG. 4, the stem is pushed in together with the nozzle body 1. The relationship between the two is determined so that the pushing amount from the initial position of 7 can reach the inside of the second pushing region S2 described above. That is, the relationship of H2> S1 is established.

Therefore, the pushing operation portion 15 of the nozzle body 1 can be manually adjusted only by setting the movable piece 3 in the operating posture shown in FIG. 5 and limiting the width H1 of the nozzle body 1 which can be pushed in to a small width. The amount of spray from the spray port 11 can be suppressed to a small level by pressing the nozzle without pressing. Further, when the movable piece 3 is set in the retracted position shown in FIGS. 1 to 4 so that the width H2 (see FIG. 4) in which the nozzle body 1 can be pushed is not restricted by the movable piece 3, the nozzle body 1 The amount of spray from the spray port 11 is increased by pushing the push-in operation unit 15 without any manual adjustment.
