BACKGROUND OF THE INVENTION
The present invention relates to an aerosol product for human body. More particularly, the present invention relates to an aerosol product for human body capable of performing effective injection both in the case of injecting a chemical liquid while being pressed against the human body and in the case of injecting it away from the human body.
[0002]
[Background Art and Problems to be Solved by the Invention]
Conventionally, aerosol products used for the human body such as anti-inflammatory analgesics have been used in so-called spray types that are sprayed in the form of a mist on the human body (affected area). In this form, the chemical solution can be sprayed over a wide range, but if it is sprayed from a distance close to the human body, it is overcooled and feels hurt. Furthermore, since the chemical | medical solution injected by the expansion | swelling of the volume when a propellant vaporizes becomes very fine particle | grains, there existed a problem which scatters on an injection surface and a user attracts | sucks.
[0003]
On the other hand, as an aerosol apparatus that injects a chemical solution in close contact with the human body, there is an aerosol apparatus that includes a spray button provided with a barrier that rises around an injection port and that forms a passage that connects the internal space of the barrier and the outside. (Actual 6-19532). In this aerosol device, when the spray button is pressed against the human body and sprayed, the chemical solution diffuses only inside the barrier and adheres to the affected part, so that the chemical solution does not scatter and the user is not likely to suck.
[0004]
However, this type of aerosol product is designed to have a small amount of propellant and a small amount of spray so that it can be sprayed from close range. Not suitable for jetting.
[0005]
In addition, in this form of aerosol product, the aerosol valve is opened by pressing against the affected area and the liquid medicine is injected, so it is necessary to press with a predetermined force or more (the aerosol valve needs to press the stem and the stem rubber with a spring. Although it is sealed by being positioned upward, 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 spray in places where it is difficult to reach, and it is easy to feel pain in the affected area due to the force of pressing, and the feeling of use is poor. In addition, there is an aerosol device that is sprayed with a finger while being pressed against an affected area, but this aerosol device is also difficult to use in a place that is difficult to reach.
[0006]
The present invention has been made to solve such a problem, and it is possible to perform effective injection both in the case of injecting a chemical solution by pressing against an affected part of a human body and in the case of injecting away from the affected part. The purpose is to provide aerosol products.
[0007]
[Means for Solving the Problems]
The aerosol product of the present invention includes an aerosol valve capable of injecting a chemical liquid in accordance with movement of a valve stem, and a spout having at least one injection port provided at the tip of the valve stem,
The spout is provided around the ejection port, and has a pressure-sensitive part having a contact surface for a relatively wide range of human bodies, and an operation part for manual operation.
When the pressure-sensitive part of the spout is pressed against the human body and pressed laterally, the aerosol valve opens and can spray the chemical solution, and when the manual operation is performed by pressing the operating part of the spout away from the human body In addition, the aerosol valve is opened, and a chemical solution can be injected.
[0008]
It is preferable that a plurality of spout injection ports are formed.
[0009]
When the pressure-sensitive part of the spout is pressed against the human body, the aerosol valve is opened and a chemical solution can be injected with a predetermined first injection amount, and when the operating part of the spout is manually operated, It is preferable that the aerosol valve is opened so that the chemical liquid can be injected with a second injection amount larger than the first injection amount.

DETAILED DESCRIPTION OF THE INVENTION
Next, the aerosol product of the present invention will be described in more detail with reference to the drawings. 1 is a partially cutaway front view of a main part of an aerosol product as an embodiment of the aerosol product of the present invention, FIG. 2 is a cross-sectional view of the spout of FIG. 1, and FIG. 3 is a front view of the spout of FIG. FIG. 4, FIG. 4 is an explanatory view showing a state in which the spout of FIG. 1 is lightly pressed against the neck or shoulder, and is a first usage pattern of the aerosol product of FIG. 1, and FIG. 5 is a diagram of the aerosol product of FIG. FIG . 6 is an explanatory view showing a state in which the spout of FIG. 1 is sprayed away from the foot, which is a usage form of FIG. 2 , and FIG. 6 is a cross-sectional explanatory view of an aerosol valve adjustable in injection amount applied to the aerosol product of the present invention . the cross-sectional view showing a state in which tilting the valve stem of FIG. 6, FIG. 8 is a sectional view showing a state in which the press today the valve stem of FIG.
[0014]
The aerosol product shown in FIGS. 1 to 3 includes an aerosol container 1 filled with an aerosol composition composed of a chemical liquid and a propellant for injecting the chemical liquid, an aerosol valve 2 fixed to the upper end opening of the aerosol container 1, The spout 3 is fixed to the tip of the aerosol valve 2.
[0015]
The spout 3 includes a pressure-sensitive unit 4 having a contact surface that contacts a wide range of human bodies that are pressed against human skin or hair, and an operation unit 5 that is manually operated. The spout 3 has an injection port 3a 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, the 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 drug used for the aerosol product, the purpose of use, and the like. When multiple injection ports are formed, the momentum of injection is dispersed, so when injected from a close distance, the cooling sensation due to the heat of vaporization of the liquefied gas is alleviated, and when sprayed away from the human body, Spattering can be reduced. Moreover, if a plurality of injection ports are provided, it is possible to inject over a relatively wide range.
[0016]
An elliptical pressure-sensitive portion 6 that is pressed against a human body is formed around the ejection port 3a. In the present embodiment, the entire tip surface of the elliptical pressure-sensitive portion 6 is the contact surface 4. The pressure sensing unit 6 senses only the space in which the chemical solution can diffuse in the pressure sensing unit and the propellant that injects the chemical solution so that the chemical solution does not leak and scatter from the pressure sensing unit when sprayed against the human body. It is preferable to provide a passage that discharges to the outside of the pressure unit.
[0017]
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 is indicated by the arrow I in FIG. 1. The spout is pushed obliquely downward by the hinge 3b, so that the stem is pushed 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 surface 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 solution is introduced into the valve stem and injected from the injection port.
[0018]
Further, since the contact surface 4 is located at a position away from the valve stem 7, the valve stem 7 can be swung and sprayed simply by lightly pressing it against the human body according to the lever principle. Furthermore, since the contact surface is in contact with the human body over a wide range, when the valve stem 7 is pushed down, the load applied to the human body is small and no pain is felt.
[0019]
In addition, since the medicine can be prevented from being scattered by pressing the pressure-sensitive part 6 against the human body and spraying, the user can be prevented from sucking the medicine and the medicine can be effectively attached.
[0020]
As another injection mode, as shown in FIG. 5, if the injection port 3 a of the spout 3 is directed away from the foot L or the like and the operation unit 5 of the spout 3 is pressed with the finger F, the spout 3 is shown in FIG. 1. The valve stem 7 is pushed in along the axial direction. At that time, the chemical solution is ejected from the ejection port 3a in the same manner as when the spout 3 is pressed in the lateral direction.
[0021]
Further, in the present invention, as shown in FIG. 6 , an aerosol valve that can be injected by two types of movement of the valve stem 7, that is, swinging and vertical movement, is used, and the position of the stem hole 9 of the valve stem 7 and the spout 3 By adjusting the tilting direction when the pressure-sensitive part 6 is pressed, the injection amount when the pressure-sensitive part 6 is pressed against the human body for injection and when the operation part 5 is pressed with the finger to be injected is set. Can be changed. For example, when the valve stem 7 tilts, one stem hole 9 is released (see FIG. 7 ), and when the valve stem 7 is pushed down in the axial direction, the two stem holes 9 are opened ( FIG. 8 ) . See), an aerosol valve is used in which the stem tilting direction and the position where the stem hole 9 is provided are in the same direction. In this case, as shown in FIG. 2, when the pressure sensitive part 6 is pressed against the human body, a relatively small amount of the first injection amount (about 0.05 to 1 ml / second) of the aerosol composition is applied to the valve stem 7. And can be sprayed to the human body from the spout 3a of the spout 3. On the other hand, when the operation unit 5 is pushed down with a finger, a large amount of the second injection amount (about 0.1 to 3 ml / second) of the aerosol composition can be injected onto the human body. As a result, when it is pressed against the human body and injected from a close distance, the injection amount decreases, so that the stimulation by the injection pressure can be reduced and the rebound of the chemical liquid on the human body surface that has injected the chemical liquid can be reduced. Furthermore, when the operation unit 5 is pushed down with a finger and sprayed from a predetermined distance, the amount of spray increases, so that the chemical solution is easy to spread and can be adhered over a wide range.
[0022]
Aerosol products shown in Figure 6-8, the valve stem 7 that has two movement of the swinging and vertical movement.
[0023]
Examples of the aerosol composition used in the aerosol product of the present invention include anti-inflammatory analgesics, blood circulation promoters, bactericides / disinfectants, anti-itch agents, athlete's foot drugs, and rash prevention applied to the shoulder, neck, back, limbs, etc. of the human body. A chemical solution such as an agent, a hair restorer, an antiperspirant, a deodorant, or a chemical solution such as a set agent, a treatment agent, or a protective agent applied to the hair is applicable.
[0024]
【The invention's effect】
Since the aerosol product of the present invention can be sprayed in a wide range of two modes, ie, a wide range of spraying and a local spraying, it can be used properly according to the intended use such as the location and size of the spray. For example, when the shoulder is stiff, it can be pressed and sprayed, and when the ankle or the like is aimed, it can be sprayed away.
[0025]
In addition, when the contact surface of the tip of the pressure-sensitive part of the spout is pressed against the human body and sprayed, it is possible to prevent the drug from being scattered, and there is no possibility that the user will suck the drug. Can be attached.
[0026]
In addition, when the spout is pressed against the valve stem while swinging, it is possible to set the position of the power point high with the lever principle. Since the contact surface is in contact with the human body, the force applied to the contact surface is dispersed and there is no pain or discomfort.
