The present invention relates to a safe device for discharging residual gas of an aerosol can, and in particular, all of the residual gas and contents of an aerosol can that are exhausted as garbage by being used up for safe disposal and recycling of an aerosol can (pressure vessel) are all easily and easily operated. The aim is to provide a safe discharge device for residual gas in an aerosol can that can be safely released.

In general, an aerosol can filled with a gas such as a high-pressure liquefied gas and the contents to be sprayed in a sealed container is widely used for insecticide, paint, fragrance, hair, fuel, and the like.

The structure of the aerosol can is a mount cap housing is fastened to the top of the aerosol can, a spring coupled to support the stem upwards in the valve housing is coupled, the outer periphery of the packing between the top of the housing and the fastening portion of the mount cap The edge is tightly fixed.

In addition, the stem flowing upward to the center portion of the mount cap is formed with a distribution hole in the middle portion, the discharge passage is formed therein.

The valve device of the conventional aerosol can has an external force acting when the stem is pressed downward, the spring is compressed, the packing is bent to open the flow hole of the stem, the contents filled in the aerosol can is filled with the flow pipe and valve housing Inner side of the, through the distribution hole of the stem and the discharge passage of the stem are sequentially discharged.

In addition, when the external force pressed on the stem is removed, the spring is extended by the restoring elasticity, the stem protrudes and returns to its original position, and the packing is opened in its original form, blocking the flow hole of the stem, thereby preventing the discharge of the contents.

In the valve device of the conventional aerosol can, the contents are discharged when the stem is pressed by the external force as above, and the discharge of the contents is blocked when the external force is removed.

Such conventional aerosol cans may cause a safety accident when the internal pressure is excessively increased above a prescribed pressure due to a high outside temperature and a handling environment due to the residual gas inside when disposing after using the contents.

For example, if the aerosol cans disposed of in the hot weather are exposed to direct sunlight for a long time, the internal pressure of the aerosol cans may be excessively high, which may cause the aerosol cans to explode.

Therefore, in order to prevent this, when aerosol cans are used and disposed of, the aerosol cans are punched out and disposed. Since it is cumbersome to drill holes in the aerosol cans, the aerosol cans are often disposed of without being punched, and there is a possibility that an accident due to the explosion of the discarded aerosol cans may occur.

The present invention has been devised to solve the above problems and defects as described above, and all of the remaining gas and contents of the aerosol cans, which are exhausted as wastes, are used for safe disposal and recycling of the aerosol cans with simple and easy operation. It is an object of the present invention to provide a safe discharge device for residual gas of an aerosol can which can be safely released.

In order to achieve the above object, the safe discharge device for residual gas of an aerosol can according to the present invention has a mount cap coupled to an upper end of an aerosol can, and an injection cap coupled to an upper portion of the mount cap. The valve is coupled, the injection button for opening and closing the stem of the valve to the inside and inside of the cylindrical inner guide wall of the injection cap is coupled to move up and down, the upper surface of the injection button to rotate the rotary button for rotating the injection button Forming, and the main wall of the injection button is formed with projections on both sides, the inner guide wall of the injection cap is formed to each gradually lower the height from the top to the bottom of the inclined cam surface is the projection of the injection button, On each of the lower side of the inclined cam surface to form a locking groove that the projection of the injection button is caught, In order to exhaust the aerosol can disposed of when the residual gas is configured to be capable of fixing the injection button to the bottom of the valve-opening position.

The safety gas discharge device of the aerosol can of the present invention can be rotated by a certain angle in a clockwise direction when the product is fully used by pressing a spray button coin or the like, and then the projection of the spray button descends along the inclined cam surface of the spray cap. It is caught by the locking groove of the cam surface, the ejection button is maintained in a stable state in which the remaining gas is discharged, so that all the remaining gas and contents inside the aerosol can is safely discharged.

Referring to the operation of the safe device for discharging the residual gas of the aerosol can according to an embodiment of the present invention as follows.

First, the injection button 30 of the aerosol can is pressed by the user in FIGS. 1, 2 (a), 3, 4, 8 and 10 and the stem 13 is pressed downward as shown in FIG. 9. When the spring 14 is compressed, the packing 15 is bent, the flow hole 13b of the stem 13 is opened, and the contents filled in the aerosol can are filled with the flow pipe 17 and the valve housing 12. Inner side of the), the distribution hole 13b of the stem 13, the discharge passage 13a of the stem 13 and the distribution groove 31 of the injection button 30 are sequentially discharged.

In addition, when the force pressing the stem 13 in the state of FIG. 9 is removed, the spring 14 is extended by the restoring elasticity, and the stem 13 protrudes as shown in FIG. 8 to return to the original position, and the packing 15 is originally Spread in form to block the distribution hole (13b) of the stem 13 is blocked the discharge of the contents.

If such aerosol can is to be discarded after use, the fitting groove 34 formed on the upper surface of the injection button 30 in the state of FIGS. 1, 2 (a), 3, 4, 8 and 10 is to be disposed. Inserting a tool such as a coin, and pressing the injection button 30 to the lower side both projections 32 formed on the main wall of the injection button 30 is located on the lower side of the two vertical guide grooves 22.

Subsequently, when the spray button 30 is rotated in the clockwise direction as shown in FIG. 2 (b), as shown in FIG. 5, both protrusions 32 of the spray button 30 move on both inclined cam surfaces 23, and the spray button 30 When rotated clockwise by about 122 degrees, both projections 32 of the injection button 30 are caught by the locking groove 24 formed at the lower side of the inclined cam surface 23 on both sides.

Accordingly, the injection button 30 is moved downward in the state of Figures 4, 8 and 10 as shown in Figures 6 and 11, the lower injection button 30 is the projection 32 of the projection 32 is inclined cam surface ( Since the 23) is caught in the locking groove 24, it is stably maintained at the lower portion that is not moved upward, and thus, when the injection button 30 is moved downward, the contents are discharged as in FIG. do.

Therefore, when disposing after using the aerosol cans, the spray button 30 is rotated only once by using a coin or the like to move downward to make the remaining gas discharged, and thus the state is kept stable even afterwards. The remaining gas is completely discharged, and no accidents caused by residual gas occur at any place in the home, garbage dump or landfill.

As described above, the safety gas discharge device for aerosol cans according to the present invention is moved to the lower side by lightly rotating by using a coin or the like that can be easily found by using the injection button around when discarding the aerosol can after use. It is possible to safely discharge residual gas, which can prevent safety accidents caused by residual gas in the aerosol can. Moreover, the aerosol can in which the residual gas is discharged can be easily collected and recycled. There is an advantage that contributes advantageously.
