Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to aerosol products for the human body. More specifically, the present invention relates to an aerosol product for a human body capable of performing effective injection in both a case where a chemical solution is sprayed by pressing against a human body and a case where a chemical solution is sprayed away from a human body.

[0002]

2. Description of the Related Art Heretofore, as aerosol products used for the human body, such as anti-inflammatory analgesics, a so-called spray type, which is sprayed into the human body (affected part) in a mist, has been used. In this mode, the liquid medicine can be sprayed over a wide range. However, if the liquid medicine is sprayed from a distance close to the human body, it is cooled too much and is damaged. Furthermore, since the chemical liquid ejected by the expansion of the volume when the propellant evaporates becomes very fine particles, there is a problem that the chemical liquid scatters on the ejection surface and is sucked by the user.

On the other hand, as an aerosol device for injecting a chemical solution in close contact with a human body, an aerosol provided with a barrier which rises around an injection port, and which has a spray button which forms a passage for communicating the internal space of the barrier with the outside. There is a device (Japanese Utility Model No. 6-19532). In this aerosol device, when the ejection button is pressed against a human body to eject the medicine, the medicine is diffused only inside the barrier and adheres to the affected part, so that the medicine does not scatter and there is no fear that the user may inhale.

However, this type of aerosol product is designed to have a small amount of propellant and a small amount of propellant so that it can be propelled from a very short distance. It is not suitable when you want to spray a chemical solution.

In this type of aerosol product, an aerosol valve is opened by pressing against an affected part, and it is necessary to press with a predetermined force or more in order to inject a chemical solution. The rubber is sealed by positioning it upward, but in order to inject, it is necessary to lower the stem against the repulsive force of the spring.) For this reason, it is difficult to inject into places that are hard to reach, and it is easy to feel pain in the affected part due to the pressing force, and the usability is poor. In addition, there is an aerosol device that performs a jetting operation with a finger while pressing the affected portion, but this aerosol device is also difficult to use in a place that is difficult to reach.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and performs effective injection in both cases where a medical solution is ejected by pressing against an affected part of a human body and when the medicine is ejected away from the affected part. The aim is to provide an aerosol product that can be used.

FIG. 15 is a sectional view showing a state where the stem is pushed into the first stage, and FIG. 15 is a sectional view showing a state where the valve stem of FIG. 13 is pushed into the second stage.

The aerosol product shown in FIGS. 1 to 3 comprises an aerosol container 1 filled with an aerosol composition comprising a drug solution and a propellant for spraying the drug solution;
The aerosol valve 2 is fixed to the upper end opening of the aerosol valve 2, and the spout 3 is fixed to the tip of the aerosol valve 2.

The spout 3 includes a pressure-sensitive portion 4 having a contact surface that contacts a wide range of the human body pressed against the skin or hair of the human body, and an operation portion 5 that is manually operated.
The injection port 3a of the spout 3 is opened in a direction inclined by about 5 to 80 degrees with respect to the axial direction of the valve stem 7. In this embodiment, three injection ports 3a are provided. The invention is not limited to this, and the shape and number of the injection ports may be determined in consideration of the medicine used in the aerosol product, the purpose of use, and the like. When multiple injection ports are formed, the momentum of the injection is dispersed, so when injected from a close distance, the cooling sensation due to the heat of vaporization of the liquefied gas is reduced, and when injected away from the human body, Scattering can be reduced. In addition, if a plurality of injection ports are provided, injection can be performed over a relatively wide range.

An elliptical pressure-sensitive portion 6 is formed around the injection port 3a and pressed against a human body. In the present embodiment, the entire distal end surface of the elliptical pressure-sensitive portion 6 is the contact surface 4. The pressure-sensitive portion 6 senses only the space in which the chemical solution can be diffused in the pressure-sensitive portion and the propellant that injects the chemical solution so that the chemical solution does not leak and scatter when pressed against the human body. It is preferable to provide a passage for discharging to the outside of the pressure portion.

When using the aerosol product configured as described above, for example, as shown in FIG. 4, if the contact surface 4 of the spout 3 is lightly pressed against the neck N or the shoulder, the spout 3 becomes as shown in FIG. Although the spout is pressed substantially in the horizontal direction indicated by the arrow I, the spout is pressed down obliquely downward by the hinge 3b, so that the stem is pressed down in the axial direction. At that time, inside the aerosol valve 2, the inner peripheral portion of the packing 8 is turned downward, and the stem hole 9 on the side of the valve stem 7 is exposed inside the aerosol container 1, so that the airtight state inside the aerosol container is released, The chemical is introduced into the valve stem and injected from the injection port.

Since the contact surface 4 is located at a position away from the valve stem 7 upward, the valve stem 7 can be swung and ejected by lightly pressing against a human body by the leverage principle. Further, since the contact surface contacts the human body over a wide range, the load applied to the human body when the valve stem 7 is pushed down is small, and the user does not feel pain.

Furthermore, the medicine can be prevented from being scattered by pressing the pressure-sensitive part 6 against the human body and ejecting the medicine, so that there is no fear that the medicine is sucked by the user, and the medicine can be effectively attached. it can.

As another injection form, as shown in FIG. 5, the injection port 3a of the spout 3 is directed away from the foot L or the like, and the operation section 5 of the spout 3 is pressed with a finger F. Is pushed in the direction of arrow II in FIG. 1, whereby the valve stem 7 is pushed along the axial direction.
At that time, the chemical is ejected from the ejection port 3a in the same manner as when the spout 3 is pressed in the lateral direction.

Further, as still another embodiment of the present invention, as shown in FIG. 6, a spout 32 is connected to a valve stem 31 of a normal aerosol valve and has a pressure-sensitive portion 33 pressed against a human body. This is a simple configuration in which an operation unit 34 that is manually operated is provided in a part. If the spout 32 is pressed against the pressure-sensitive portion 33 with the neck or shoulder or the operation portion 34 is pressed with a finger, the spout 32 is pushed obliquely downward by the hinge 32b, so that the valve stem 31 is pushed down along the axial direction. The liquid medicine is injected from the injection port 32a.

Next, as still another embodiment of the present invention, as shown in FIGS. 7 to 9, a spout 41 is connected to a valve stem 31 of a normal aerosol valve.
The pressure-sensitive part 42 pressed against the human body and the operation part 43 manually operated are composed of separate components. Pressure sensing part 42
Has an injection path 42a connected to the valve stem 31. An opening 43a is formed at the center of the operation unit 43, and a projection 46 is formed downward from a peripheral edge of the opening 43a.

As shown in FIG. 8, in the case of the spout 41, when the operation portion 43 is pressed by a finger, the projection 46 causes the valve stem 31 to move in the axial direction through the pressure sensing portion 42, as shown in FIG. Down, and the liquid medicine is ejected from the ejection port 47.

When the skin S of the human body is pressed against the contact surface 44 of the pressure sensing portion 42 and ejected, the pressure sensing portion 42 moves downward inside the opening 43a of the operation portion 43 as shown in FIG. It moves and pushes down the valve stem 31 to inject the chemical. Pressure-sensitive portion 4 pressed against skin S at the time of injection

No chemical solution leaks from

The aerosol valves connected to the spouts 32 and 41 shown in FIGS. 6 and 7 are not particularly limited in the present invention.

In the present invention, as shown in FIG. 10, an aerosol valve capable of jetting by two kinds of movements of the valve stem 7, ie, swinging and vertical movement, is used.
By adjusting the position of the stem hole 9 of the valve stem 7 and the tilting direction when the pressure-sensitive part 6 of the spout 3 is pressed, the pressure-sensitive part 6 is pressed against the human body to perform injection, and the finger is operated. It is possible to change the injection amount when the part 5 is pressed and injected. For example, one stem hole 9 is released when the valve stem 7 is tilted (see FIG. 11), and two stem holes 9 are opened when the valve stem 7 is pushed down in the axial direction (FIG. 12). ), And an aerosol valve is used in which the stem tilt direction and the position where the stem hole 9 is provided are the same. In this case, as shown in FIG. 2, when the pressure-sensitive portion 6 is pressed against the human body, a relatively small amount of the first spray amount (about 0.05 to 1 ml / sec) is applied to the valve stem 7. , And can be injected into the human body from the injection port 3a of the spout 3. on the other hand,
When the operation unit 5 is pressed down with a finger, a large amount of the second aerosol composition (about 0.1 to 3 ml / sec) can be sprayed on the human body. As a result, when the liquid is pressed against the human body and the liquid is injected from a short distance, the injection amount is reduced, so that the stimulus due to the injection pressure can be reduced and the rebound of the liquid on the surface of the human body from which the liquid has been injected can be reduced. Furthermore, when the operation unit 5 is pressed down with a finger and ejected from a predetermined distance, the ejection amount increases, so that the chemical liquid is easily spread and can be attached to a wide area.

In the aerosol product shown in FIGS. 10 to 12, the valve stem 7 makes two kinds of movements: swinging and vertical movement. However, the present invention is not limited to this. Other embodiments may be used as long as the valve stem can be operated so as to be adjustable.

For example, as another embodiment of the present invention, the aerosol product shown in FIGS. 13 to 15 can adjust the injection amount by pushing the valve stem 11 in two stages. The aerosol product shown in FIGS. 13 to 15 has an aerosol valve 11 fixed to an upper end opening of an aerosol container (not shown) filled with an aerosol composition and a tip of the aerosol valve 11 as in the above-described embodiment. The spout 12 is fixed to the spout 12.

The aerosol valve 11 includes a valve stem 1
When 3 is pushed to the first stage (see FIG. 14), it functions as a metering valve, and when it is pushed to the second stage (see FIG. 15), it functions as an injection valve capable of normal continuous injection.

Specifically, the valve stem 13 is fitted to the packing 14 so as to be vertically movable, and the flange 15 protruding near the center is provided with the first compression coil spring 1.
6 is in contact with the upper end. Further, a valve body 18 for closing an opening 17a at a lower portion of the chamber 17 is provided below the valve stem 13. When the valve element 18 moves downward to the first stage, the valve element 18 comes into close contact with the ring-shaped packing provided in the lower opening 17a and shuts off the inside of the aerosol container, thereby preventing the aerosol composition from being introduced into the chamber. You. When the chamber 17 is further moved down to the second stage, the chamber 17 is opened to the inside of the aerosol container through the concave portion 19 formed on the side surface of the valve element 18.

The aerosol products shown in FIGS. 13 to 15 are provided with a second compression coil spring 21 inside the chamber 17. The second compression coil spring 21 is connected to the valve stem 1
3 is pushed by the step portion 20 formed at the lower portion of the valve stem 13 only while being pushed from the first stage to the second stage, and is separated from the step portion 20 while being pushed from the state before injection to the first stage. In addition, it is arranged.

The spout 12 has a contact surface 22 pressed against the human body and an operation unit 23 manually operated. Around the spout 12 a of the spout 12, a circular feeling is pressed against the affected part of the human body. A pressure part 24 is formed. In the aerosol products of FIGS. 13 to 15, the injection port 12 a is opened along the axial direction of the valve stem 13, and the entire distal end surface of the circular pressure-sensitive portion 24 is the contact surface 22.

When the aerosol product of FIGS. 13 to 15 is used, as shown in FIG. 14, if the contact surface 22 of the spout 12 is lightly pressed against the neck or the shoulder, the spout 12 and the valve stem 13 are moved to the first stage. When pushed down, the stem hole 25 of the valve stem 13 moves below the packing 14, communicates with the inside of the chamber 17, and a predetermined first injection amount (0.05 to 0.05) inside the chamber 17 closed by the valve body 18. 3ml / time, final injection amount is 0.1
５5 ml) of the aerosol composition. At this time, by injecting the pressure-sensitive portion 24 against the human body, the medicine can be prevented from being scattered, and there is no fear that the user may inhale the medicine, so that the medicine can be effectively attached.

As another injection form, as shown in FIG. 15, the injection port 12a of the spout 12 is directed away from the foot and the like, and the operating portion 23 of the spout 12 is pressed strongly with a finger, so that the valve stem 13 is pushed into the second stage while compressing the first and second compression coil springs 16 and 21. At this time, in order to open the chamber 17 into the aerosol container through the concave portion 19 of the valve body 18, a large amount of the second injection amount (about 0.1 to 3 ml / sec) of the chemical is introduced into the valve stem 13 and the spout 12 can be injected into the affected part of the human body.

As shown in FIGS. 14 and 15, from the first stage to the second stage
When shifting to the stage, it is necessary to compress the second compression coil spring 21. Therefore, it is possible to easily confirm whether the injection state is the first stage or the second stage depending on the difference in the operating force.

The aerosol composition used in the aerosol product of the present invention includes, for example, antiphlogistic analgesics, blood circulation promoters applied to the shoulder, neck, back or limbs of the human body,
Chemical solutions such as disinfectants, anti-itch agents, athlete's foot medicine, anti-fever agents, hair restorers, antiperspirants, deodorants, etc., or chemical solutions such as set agents, treatment agents, and protective agents applied to hair can be applied. is there.

[0037]

The aerosol product of the present invention can be used in two types of spraying, that is, widespread spraying and local spraying, so that it can be used properly according to the application such as the place and size of the spraying. For example, in the case of stiff shoulders, the injection can be performed by pressing, and when the ankle or the like is sprained, the injection can be performed apart.

Further, when the contact surface of the pressure-sensitive part tip surface of the spout is pressed against the human body and ejected, the scattering of the medicine can be prevented, and there is no fear that the user may inhale the medicine. Can be effectively attached.

When the spout is pressed against the valve stem while being swung, the position of the power point can be set high by the leverage principle, so that the injection can be performed only by lightly pressing against the human body. Further, since the contact surface contacts the human body over a wide range, the force applied to the contact surface is dispersed, and there is no pain or discomfort.
