2. Description of the Related Art Conventionally, every time an explosion accident of an aerosol valve occurs, the cause of the explosion accident is investigated, the people involved make an effort to eliminate the cause, and various explosion-proof aerosol valves have been developed. It was As one of them, the applicant of the present invention has developed a pressure filling valve that also serves as a safety valve (see Japanese Patent Publication No. 44-1760). But,
The safety valve and pressure filling valve is a safety valve and pressure filling valve in which a discharge and filling side hole is provided on the circumferential side of a container cap such as a mountain cap, and an elastic valve such as rubber that opens and closes the side hole is fitted from the outside. However, measures against deterioration of elastic material such as rubber of elastic valve such as rubber due to ozone and ultraviolet rays from the outside, heat rays from the sun and other obstructive factors cannot be said to be sufficient, and drastic structural improvement Or other appropriate measures were needed.

[0003]

Therefore, there is provided an explosion-proof aerosol valve which has the above-mentioned functions and is capable of sufficiently eliminating ozone and ultraviolet rays from the outside, heat rays from the sun, and other obstructive factors. This is the first object of the present invention. Also, without impairing the function of the conventional aerosol valve, and further, during or after the use of the aerosol valve or very little, so as not to explode the aerosol valve before use etc. This is the second object of the present invention. Further, without changing the structure of the aerosol jet valve main body which maintains the function of the conventional aerosol valve, and further, during or after the use of the aerosol valve, or very little, before the use of the aerosol valve. It is the third object of the present invention to prevent the explosion of the. In addition, without changing the structure of the aerosol injection valve body that maintains the function of the conventional aerosol valve, simply changing the shape of the mountain cap from a flat shape to a concavo-convex shape is sufficient to achieve that function. It is a fourth object of the present invention to form an explosion-proof aerosol valve and a pressure-fillable explosion-proof aerosol valve. Further, conventionally, has been a pressure filled into the aerosol container via the aerosol valve, because less through the gap between the stem and the mountain cap the filling opening, strong 30 Kg / cm ² to 50 Kg / cm ² Filled with pressure. Then, the internal pressure when made with the product was 3 Kg / cm ² to 4 Kg / cm ^2, even at high, is about 8 Kg / cm ^2. The part of the aerosol container where gas leaks is the seal part and the part where the stem rubber is located, and the seal part between the upper opening part of the aerosol container and the peripheral part of the mountain cap and the central opening part of the mountain cap. It is conceivable that gas leaks from between the top part in front of and the stem rubber located behind it. Therefore, the explosion-proof requirement must be such that only the propellant gas can be released at a pressure lower than the pressure resistance of the aerosol container itself, which is a product.
It is a fifth object of the present invention to complete such explosion-proof requirements. In addition, conventionally, the pressure resistance of the aerosol container is the deformation of the aerosol container,
The limit of the pressure at which it deforms is set to 13 Kg / cm ² . Therefore, a sixth object of the present invention is to set a pressure equal to or lower than the limit of deformation to an internal pressure so that only the propellant gas can be discharged at that pressure. Further, conventionally, the properties of the stem rubber interposed between the mountain cap and the housing valve, which is the main part of the aerosol injection valve body incorporated in the mountain cap, such as hardness and elasticity, and other physical properties and chemical properties. , Even if the structure or mechanism of the aerosol valve does not differ due to mechanical strength, electrical properties, other properties, or the tightening of the stem rubber used, the characteristics of the finished product may be slightly different. is there. However, even with that, if a proper adjustment technique is acquired, even if some product unevenness appears on the structure, it can be sufficiently adjusted. In consideration of the above, the present invention forms a concavo-convex portion for forming a flow path capable of discharging only propellant gas in an appropriate portion of a mountain cap incorporating an aerosol valve that has been conventionally developed. A seventh object of the present invention is to provide an explosion-proof aerosol valve capable of pressure filling such as an explosion-proof aerosol valve and an aerosol container having the explosion-proof aerosol valve.
