JP 2019-189274 A

When the contents are two-liquid hair dyes or the like, typically two aerosol containers are bundled together or an aerosol container equipped with two valve mechanisms is used. In order to eject two liquids from such an aerosol container, it is necessary to perform an ejection operation on two valve mechanisms, i.e., to press down on two stems. This requires a stronger pressing force than when there is only one stem, and when used by a consumer, the amount of pressing down may not be sufficient.

In addition, when a metered-volume valve is used as the valve mechanism, that is, when the stem is pressed down, the contents are discharged from the metered-volume chamber to the outside, but the supply of contents into the metered-volume chamber is cut off at the bottom end of the stem, and when the stem is released, the discharge of contents from the metered-volume chamber to the outside is stopped, but contents are supplied to the metered-volume chamber. In this case, the stem must be pressed down a longer distance to spray a fixed amount, and the amount of compression of the biasing member (spring) that constantly biases the stem upwards must be increased. Such a metered-volume valve requires a stronger force to press down than a normal valve mechanism, and when used by a consumer, the amount of pressure pressed down may not be enough.

In addition, when a resin spring is used as a biasing member that repels the downward depression of the stem, a stronger downward force may be required compared to a typical metal coil spring, and when used by a consumer, the amount of downward depression may be insufficient.

The first object of the present invention is to provide an ejection member for an aerosol container that requires less force for ejection. The second object is to provide an ejection member that is suitable for use with an aerosol container equipped with a special valve mechanism.

The discharge member for an aerosol container of the present invention comprises a first lever member 20, a second lever member 30, and a base 40 to which the first lever member 20 and the second lever member 30 are rotatably attached, and constitutes a double lever in which the leverage force obtained by the rotation of the first lever member 20 is used to rotate the second lever member 30, and the leverage force obtained by the rotation of the second lever member 30 is used for the discharge operation of the valve mechanism 5 of the aerosol container 2, 2A, 2B, 2C, and the first lever member 20 is supported by a first pivoting portion 21 which serves as a fulcrum. The device has an operating section 22 that is pressed down, and an action section 23 that transmits the leverage of the first lever member 20 to the second lever member 30, and the second lever member 30 has a second rotation section 31 that serves as a fulcrum, an attachment section 32 that is attached to the valve mechanism 5, and a nozzle section 33 that has a discharge hole 33a for discharging the contents released from the valve mechanism 5 to the outside, and when the operating section 22 is pressed down, the action section 23 presses down the slide surface 33b formed on the upper part of the nozzle section 33.

In the above discharge member, when the side where the first pivoting part 21 is located is defined as the front side as viewed from the mounting part 32 of the second lever member 30, it is preferable that the slide surface 33b is located on the front side, the second pivoting part 31 is located on the rear side, and the rear end of the operating part 22 is located at the same position as the second pivoting part 31 or rearward of the second pivoting part 31.

It is preferable that the slide surface 33b is inclined obliquely upward toward the discharge hole 33a.

The discharge product of the present invention is characterized in that it comprises the above-described discharge member 10 for an aerosol container and two aerosol containers 2, the two aerosol containers 2 are connected, and the second lever member 30 has an attachment portion 32 that is attached to the valve mechanism 5 of each aerosol container 2.

Another discharge product of the present invention is characterized in that it comprises the above-described discharge member 10A for an aerosol container, and an aerosol container 2A equipped with two valve mechanisms 5, and the second lever member 30 comprises an attachment portion 32 that is attached to each of the valve mechanisms 5.

Still another discharge product of the present invention comprises the above-described discharge member 10B for an aerosol container and an aerosol container 2B equipped with a valve mechanism 5, and is characterized in that the valve mechanism 5 is a fixed-volume valve that, when the stem 5a is pressed down, blocks the supply of contents into the fixed-volume chamber S but discharges the contents in the fixed-volume chamber S to the outside.

Another discharge product of the present invention includes the above-described discharge member 10C for an aerosol container, and an aerosol container 2C equipped with a valve mechanism 5, and is characterized in that the valve mechanism 5 includes a stem 5a and a resin spring (5c) that biases the stem 5a upward.

In the discharge member for an aerosol container of the present invention, the acting portion of the first lever member presses down on the slide surface formed on the upper portion of the nozzle portion of the second lever member, so that the leverage force of the first lever member is easily transmitted to the second lever member, and as a result, the force is also easily transmitted to the valve mechanism to which the second lever member is attached. In other words, the force required for the discharge operation can be reduced.

When the side where the first pivoting part is located is defined as the front side as viewed from the mounting part of the second lever member, if the sliding surface is located on the front side, the second pivoting part is located on the rear side, and the rear end of the operating part is located at the same position as the second pivoting part or further rearward than the second pivoting part, the distance between the action part of the first lever member and the operating part can be increased, and the operating part can be operated with less force.

If the sliding surface is inclined diagonally upwards toward the discharge hole, the tip of the operating part slides more easily when the operating part is pressed down, making the discharge operation smoother.

Each of the dispensing products of the present invention employs one of the above-mentioned dispensing members, so even if it uses two valve mechanisms, a fixed-volume valve, or a resin spring in the valve mechanism, the force required for dispensing is small, and even when used by a consumer, the operating part can be pushed down to a specified position, allowing the contents to be dispensed as designed.

The discharge product 1 shown in Figure 1 comprises two aerosol containers 2 and one discharge member 10 for discharging (opening) the valve mechanisms 5 (see Figure 2) of the two aerosol containers 2. Each component will be explained below, but for simplicity, the explanation will be given according to the directions (up and down, front and back, left and right) shown in Figures 1 and 2.

As shown in FIG. 2, the aerosol container 2 includes a container body 3 that contains the contents, and a valve assembly 4 that closes the opening of the container body 3. The aerosol container 2 is filled with the concentrate and a pressurizing agent (gas) for discharging the concentrate as the contents.

As shown in Figs. 1 and 2, the container body 3 is a bottomed cylinder having a bottom 3a, a body 3b, and a shoulder 3c. It has a cylindrical neck 3d extending upward from the shoulder 3c, and the upper end of the neck 3d is open. The container body 3 is made of a metal such as tinplate or aluminum, and a groove 3e is formed between the neck 3d and the shoulder 3c. The material of the container body 3 may be a synthetic resin such as polyethylene terephthalate, polyethylene naphthalate, polypropylene, or polyethylene.

The valve assembly 4 includes a valve mechanism 5, a housing 6 that accommodates the valve mechanism 5, and a mounting cup 7 that secures the housing 6 to the container body 3.

The valve mechanism 5 comprises a stem 5a with a stem hole, a stem rubber (not shown) that blocks the stem hole, and a biasing member (not shown) that constantly biases the stem 5a upward, maintaining the stem hole blocked by the stem rubber. This valve mechanism 5 is designed so that the contents contained in the aerosol container 2 can be discharged by performing an ejection operation such as pushing the stem 5a down (pushing it toward the housing 6) or tilting it, thereby releasing the blockage of the stem hole by the stem rubber. This is what is known as an aerosol valve.

The housing 6 is cylindrical with a bottom and contains the valve mechanism 5 in its internal space.

The mounting cup 7 is a metal lid made of aluminum, tin, or the like that keeps the inside of the aerosol container 2 airtight, and holds the housing 6 and the valve mechanism 5 in the center when viewed from above, with the stem 5a protruding upward. The outer periphery is crimped into the groove 3e of the container body 3 and is fixed to the container body 3. Note that screws may be provided on the container body 3 and the mounting cup 7, and they may be fixed by screwing.

The aerosol containers 2 of the above configuration are connected to the discharge member 10 by a shoulder cover 50 (described later) with the stem 5a facing upward and aligned in the left-right direction.

The discharge member 10 comprises a first lever member 20, a second lever member 30, a base 40 to which the first lever member 20 and the second lever member 30 are rotatably attached, and a shoulder cover 50 to which the base 40 is attached to the upper part (the end part on the stem 5a side) of the container body 3. The leverage obtained by the rotation of the first lever member 20 is used to rotate the second lever member 30, and the leverage obtained by the rotation of the second lever member 30 is used for the discharge operation of the valve mechanism 5 of the aerosol container 2, forming a double lever. The material of the discharge member 10 is, for example, a synthetic resin such as polybutylene terephthalate, polypropylene, or polyoxymethylene. However, it may be made of metal.

The first lever member 20 has a first pivoting part 21 that serves as a fulcrum, an operating part 22 that is operated by being pushed down, and an acting part 23 that transmits the leverage force of the first lever member 20 to the second lever member 30. This first lever member 20 is attached to the base 40 so that the first pivoting part 21 is on the front side, the operating part 22 is on the rear side, and the acting part 23 is located between the first pivoting part 21 and the operating part 22. It is also located above the second lever member 30.

The first pivoting part 21 allows the entire first lever member 20 to pivot about a left-right axis with the first pivoting part 21 as the center of rotation. Note that in FIG. 2, the first lever member 20 is pivoted by a shaft and a bearing, but it may also be a hinge that utilizes the flexibility of the material.

The operating part 22 is a part that the consumer presses down to operate it. As shown in FIG. 2, a recess 22a is provided on the top surface for the operating finger to place. In a plan view, the rear end 22b of the operating part 22 is located rearward of a second pivot part 31 (described later) of the second lever member 30. However, it may be located in the same position as the second pivot part 31.

The action portion 23 is a protrusion that protrudes downward (toward the second lever member 30), and the tip (lower end) has a spherical (semicircular) cross section. Also, since it is long in the left-right direction, it can also be said to be plate-shaped (see FIG. 1). This action portion 23 abuts against the nozzle portion 33 (described later) in front of the mounting portion 32 (described later) of the second lever member 30. Specifically, the lower end of the action portion 23 abuts against the slide surface 33b (described later) of the nozzle portion 33. The lower end of the action portion 23 is horizontal in the left-right direction, and the slide surface 33b is also horizontal in the left-right direction. Therefore, the action portion 23 abuts against the slide surface 33b at a line rather than a point, and the slide surface 33b can be pushed down evenly left and right (without tilting the nozzle portion 33).

The first lever member 20 constitutes a second type lever in which the operating part 22 is the force point, the first rotating part 21 is the fulcrum, and the action part 23 is the action point. Therefore, by rotating the first lever member 20, an increased lever force is obtained. This lever force is used as a force for rotating the second lever member 30.

The second lever member 30 comprises a second pivoting part 31 that serves as a fulcrum, an attachment part 32 that is attached (connected) to the stem 5a of the valve mechanism 5, and a nozzle part 33 that ejects the contents released from the valve mechanism 5 to the outside. This second lever member 30 is attached to the base 40 so that the second pivoting part 31 is on the rear side, the nozzle part 33 is on the front side, and the attachment part 32 is located between the second pivoting part 31 and the nozzle part 33.

The second pivoting part 31 allows the entire second lever member 30 to rotate about a left-right axis with the second pivoting part 31 as the center of rotation. Note that in FIG. 2, the second lever member 30 is pivoted by a shaft and a bearing, but it may also be a hinge that utilizes the flexibility of the material.

The mounting part 32 spans the two stems 5a, and its lower end fits over the two stems 5a. Specifically, two stem mounting openings 32a are provided at the lower end, and the stems 5a are inserted into the stem mounting openings 32a. Two flow paths are provided inside to pass the contents supplied from the stems 5a. These two flow paths are connected to the nozzle part 33.

The nozzle portion 33 has two internal flow paths that take over from the two flow paths of the mounting portion 32. The tip of the nozzle portion 33 has two discharge holes 33a for discharging the contents from each of the flow paths. The upper portion (top surface) of the nozzle portion 33 has a sliding surface 33b along which the action portion 23 of the first lever member 20 slides. This sliding surface 33b is smooth, is located between the discharge holes 33a and the mounting portion 32 (stem mounting port 32a), and is inclined obliquely upward toward the discharge holes 33a.

The second lever member 30 constitutes a second type of lever, with the slide surface 33b as the force point, the second pivoting part 31 as the fulcrum, and the mounting part 32 as the point of action. Therefore, by rotating the second lever member 30, a lever force is obtained. This lever force is used to operate the valve mechanism 5 to discharge (push down or tilt the stem 5a). In addition, since the second lever member 30 receives a lever force from the action part 23, which is the point of action of the first lever member 20, the discharge member 10 can be said to constitute a double lever.

The base 40 is a cylinder with an axis oriented in the vertical direction and flat in the front-rear direction, and the first lever member 20 and the second lever member 30 are located inside. The first rotating part 21 is located on the front side of the base 40, and the second rotating part 31 is located on the rear side. Notches 41 are provided on the front and rear of the upper end side, and the nozzle part 33 of the second lever member 30 protrudes from the front notch 41, and the rear end 22b of the operating part 22 of the first lever member 20 protrudes from the rear notch 41. The upper end is open, so that the operating part 22 can be pressed down from above. The part of the upper end where the notch 41 is not provided is located above the operating part 22, so that the operating part 22 can be prevented from being pressed down unintentionally. The lower end side is fitted and fixed to the shoulder cover 50.

The shoulder cover 50 is roughly shaped like an eight in plan view and fits over the top of the two aerosol containers 2, fixing the two aerosol containers 2 side-by-side. Note that the base 40 and the shoulder cover 50 are separate members, but they may be integrated.

When the operating part 22 of the discharge product 1 having the above configuration is pressed down (see S2 in FIG. 3), the entire first lever member 20 rotates around the first rotating part 21 as a rotation center, and the leverage obtained by the rotation is transmitted to the second lever member 30 via the acting part 23. At this time, the acting part 23 slides down the slide surface 33b while pressing down, so that the force can be transmitted efficiently. In particular, since the slide surface 33b is inclined diagonally upward toward the discharge hole 33a, the tip of the acting part 23 easily slides on the slide surface 33b. The pressed down second lever member 30 rotates around the second rotating part 31 as a rotation center, and the leverage obtained by the rotation is used to simultaneously press down or tilt the two stems 5a. As a result, the valve mechanism 5 opens, and the contents contained in the two aerosol containers 2 are discharged to the outside through the nozzle part 33.

For example, when the contents are two-liquid reactive contents such as two-liquid hair dye, and one aerosol container 2 contains a first liquid and the other aerosol container 2 contains a second liquid, it is important to eject the first and second liquids stored in the separate aerosol containers 2 at a predetermined ratio in order to achieve the desired performance. However, if the operating part 22 is not pushed down sufficiently, even if each aerosol container 2 uses a valve mechanism 5 of the same configuration, differences in the opening degree of the stem hole 5a1 may occur due to manufacturing errors, etc., and ejection may not be possible at the predetermined ratio. As described above, a relatively large force is required to push down the two stems 5a, and when used by a consumer, the pushing down of the operating part 22 may be insufficient. However, with the ejection member 10 of the present invention, even when two valve mechanisms 5 are ejected simultaneously, the operating part 22 can be pushed down with a small force, so that the consumer can push down the operating part 22 to a predetermined position. As a result of being able to fully open the stem hole, ejection can be performed at a predetermined ratio, and the desired performance can be stably achieved.

In addition, if the timing of the opening of the stem holes is off, the first and second liquids cannot be ejected in a predetermined ratio. However, in the ejection member 10 of the present invention, the arrangement direction of the stems 5a and the longitudinal direction of the action part 23 are the same. Specifically, the stems 5a (stem mounting ports 32a) are arranged in the left-right direction, and the plate-shaped action part 23 is formed long in the left-right direction. This allows the two stems 5a to be pushed down simultaneously and evenly, and the stem holes to be opened simultaneously.

When connecting two aerosol containers 2, it is preferable to set the outer diameter of the barrel 3b of the container body 3 to about 25 to 30 mm in consideration of ease of grip. However, if the outer diameter is small, the size of the discharge member 10 in the front-rear direction will naturally be small, and when the contents are discharged in a direction intersecting the connection direction of the aerosol containers 2 as in this embodiment, the distance from the fulcrum to the force point will be short and the effect of the leverage will not be sufficient. However, by arranging the first lever member 20 and the second lever member 30 one above the other, and by placing the part that receives the force from the first lever member 20 (the force point of the second lever member 30) forward of the mounting part 32 (the central axis of the aerosol container 2) and providing a flat surface (slide surface 33b) on the upper part of the nozzle part 33, the operation amount becomes longer but the operation force becomes smaller, and the two stems 5a can be reliably released.

To stop ejection, simply stop pressing down on the operating part 22. By stopping pressing down, the stem 5a returns to its original position (see S1 in Figure 3), and the valve mechanism 5 returns to the closed state.

Next, the discharge product 1A shown in FIG. 4 will be described. In the discharge product 1 in FIG. 1, two aerosol containers 2 are used, but in this discharge product 1A, as shown in FIG. 5, one aerosol container 2A equipped with two valve mechanisms 5 (stems 5a) is used. This aerosol container 2A contains two inner bags (not shown) in the container body 3, and two types of concentrate can be stored separately by storing the concentrate in the inner bag. The concentrates stored separately are discharged from separate valve mechanisms 5 (stems 5a) under the pressure of the pressurizing agent filled in the space between the container body 3 and the inner bag. In this aerosol container 2A, the distance between the two stems 5a, 5a can be made shorter than that of the aerosol container 2 in FIG. 1, so that the force of pressing down the operating part 22 can be easily transmitted evenly to the two stems 5a via the action part 23, and the two contents (concentrate) can be easily discharged at a predetermined ratio.

The discharge member 10A differs from the discharge member 10 in FIG. 1 in that it is equipped with a detachment mechanism 42 (see FIGS. 5 and 6) for detaching the base 40 from the shoulder cover 50. The detachment mechanism 42 is provided on both the left and right sides of the base 40. It works like a seesaw, where pushing one side lifts the other, and when the lower end of the detachment mechanism 42 is engaged with the claw portion 51 of the shoulder cover 50, pushing the upper end of the detachment mechanism 42 inward causes the lower end to jut outward and disengage from the claw portion 51.

As shown in FIG. 6, the shoulder cover 50 is generally cylindrical in shape to ensure continuity with the outer shape of the body 3b of the aerosol container 2. The base 40 also has a generally cylindrical outer shape. The first lever member 20 is also generally circular in plan view. As shown in FIG. 7, the first lever member 20 may have a recess 22a on the rear side for a finger to hook, or may have a non-slip surface 22c.

Other configurations are the same as those of the discharge product 1 in FIG. 1, so the same reference numerals are used and detailed explanations are omitted.

Next, we will explain the discharge product 1B shown in Figure 8. This discharge product 1B uses an aerosol container 2B equipped with a metered-dose valve.

The metered-volume valve is formed by providing a through hole 6a at the bottom of the housing 6 for passing the lower end of the stem 5a, and providing a seal material 8 on the upstream (container body 3) side of the through hole 6a, which forms a seal between the housing 6 and the container body 3 when the lower end of the stem 5a is inserted. In this metered-volume valve, as shown in the separate window of FIG. 8, when the stem 5a is pressed down, the lower end of the stem 5a is inserted into the seal material 8 to form a seal, that is, the supply of contents from the container body 3 to the housing 6 (metered-volume chamber S) is blocked at the lower end of the stem 5a, but the stem rubber 5b releases the blockage of the stem hole 5a1 when the stem 5a is pressed down, so that the contents in the metered-volume chamber S can be discharged to the outside. Also, when the stem 5a is not pressed down, the lower end of the stem 5a is not inserted into the seal material 8, that is, the blockage by the lower end of the stem 5a is released, so that the metered-volume chamber S and the container body 3 are in communication, and the contents are supplied to the metered-volume chamber S. As a result, a predetermined amount of contents (the amount accumulated in the metering chamber S) is always dispensed.

In the fixed-volume valve of the above configuration, the stem 5a comes into contact with and slides against the stem rubber 5b and the sealing material 8, so a larger downward force is required compared to a normal valve mechanism. In addition, since the lower end of the stem 5a needs to be moved up and down significantly in a fixed-volume valve, the stroke of the stem 5a is longer compared to a normal valve mechanism. Therefore, when used by a consumer, the amount of downward movement may be insufficient. However, with the discharge member 10B of the present invention, the operating part 22 can be depressed with a small force, so the consumer can be made to press the operating part 22 down to a specified position. Therefore, all of the contents in the fixed-volume chamber S can be discharged, and a constant amount of contents can always be discharged.

Other differences from the discharge product 1A in FIG. 1A include that the discharge member 10B of this discharge product 1B has only one concentrate C, so the mounting part 32 and nozzle part 33 have only one flow path, and there is also only one discharge hole 33a. Also, the shoulder cover 50 is omitted, and the base 40 is fitted directly onto the top of the aerosol container 2. As the other configurations are the same as those of the discharge product 1A in FIG. 1A, the same reference numerals are used and detailed explanations are omitted.

Next, the discharge product 1C shown in Figure 9 will be described. In the aerosol container 2C of this discharge product 1C, a resin spring is used as the biasing member 5c that biases the stem 5a. The resin spring is a number of rod-shaped bodies that rise upward from the bottom of the housing 6. The rod-shaped bodies are arranged in a roughly circular shape around the lower end of the stem 5a, and when the stem 5a is pressed down, the rod-shaped bodies are pushed by the lower end of the stem 5a and deform so as to spread outward. When the downward pressure on the stem 5a is stopped, the rod-shaped bodies try to return to their original position and push up the stem 5a.

When using a valve mechanism 5 that uses such a resin spring, a stronger downward force may be required than with a typical metal coil spring, and when used by a consumer, the amount of downward pressure may not be sufficient. However, with the discharge member 10C of the present invention, the operating part can be depressed with a small force, allowing the consumer to press down the operating part 22 to a specified position.

The aerosol container 2C of this discharge product 1C uses a two-layer bottle as the container body 3, in which an inner bottle 13b is housed inside an outer bottle 13a. The inner bottle 13b is flexible and is filled with concentrate C. A pressurizing agent P is filled between the outer bottle 13a and the inner bottle 13b, and when the valve mechanism 5 is opened, the inner bottle 13b shrinks and deforms, and concentrate C is discharged to the outside from the stem 5a.

The stem 5a is a so-called coaxial stem (double stem) in which an additional stem (outer stem 15b) is provided on the outer periphery of a bottomed stem (inner stem 15a). The inner stem 15a and the outer stem 15b each have a stem hole 5a1, and these stem holes are each blocked by a separate stem rubber 5b.

The stem hole 5a1 of the outer stem 5a is connected to the space between the outer bottle 13a and the inner bottle 13b. Specifically, an outer passage R1 is formed that runs from between the neck of the outer bottle 13a and the neck of the inner bottle 13b through the outer periphery of the housing 6 to the stem hole 5a1 of the outer stem 15b. However, because the upper end of the outer stem 5a is blocked by the mounting portion 32 of the second lever member 30, the pressurizing agent P is not discharged even when the stem 5a is pressed down. The outer passage R1 is used exclusively when filling the pressurizing agent P.

On the other hand, the stem hole 5a1 of the inner stem 5a is connected to the inside of the inner bottle 13b. Specifically, an inner passage R2 is formed that runs from a hole provided at the bottom of the housing 6 through the housing 6 to the stem hole 5a1 of the inner stem 5a, and the concentrate C is discharged by pushing down the stem 5a. The inner passage R2 is also used when filling the concentrate C.

Another difference between this discharge product 1C and the discharge product 1A in FIG. 1A is that a screw cap 17 is used to secure the valve mechanism 5 and the housing 6 to the container body 3. Also, since there is only one concentrate C, there is only one flow path for the attachment part 32 and the nozzle part 33, and there is also only one discharge hole 33a. As the other components are the same as those of the discharge product 1A in FIG. 1A, the same reference numerals are used and detailed explanations are omitted.

Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention. For example, in FIG. 1, the discharge hole 33a is separated to the outside, but it may be joined along the way.
