Description

[Detailed description of the invention] Industrial application field The present invention relates to a degassing device for aerosol containers, which removes residual gas from used aerosol containers and prevents explosions and other accidents caused by residual gas. The aim is to prevent this from occurring.

Conventional technology Conventionally, residual gas from an aerosol container whose contents have been used is removed, and the residual gas is removed.
For those trying to prevent the occurrence of explosion accidents, etc.
Utility Model Application Publication No. 112764/1983, Publication No. 39015/1983, Publication No. 52963/1983, Publication No. 177397/1983
There are many publications such as Japanese Publications, but all of them aim to exhaust the residual gas by driving needles, nails, etc. into the aerosol container. Since the contents spew out, it has the disadvantage of being dangerous to work with.

Problems to be solved by the invention This invention aims to solve the above-mentioned problems by removing residual gas from used aerosol containers and preventing explosion accidents caused by residual gas. In order to prevent this, the aim is to ensure safe evacuation by ensuring that the direction of ejection of residual gas and residual contents is on the opposite side from the operator.

Means for solving the problems In order to solve the problems mentioned above, the present invention
A driving needle for driving into the aerosol container and penetrating the outer peripheral wall is protruded from the lower end of the exhaust body, and a holding handle is formed on the side of the exhaust body, and a handle is formed on the side of the exhaust body opposite to the side where the handle is formed. An exhaust nozzle protrudes from the side surface, and the exhaust nozzle and the driving needle are communicated through an exhaust passage.

Further, it is preferable to provide a suppressor for suppressing exhaust gas in a part of the exhaust path from the outer surface of the opening of the driving needle to the outer surface of the discharge port of the exhaust nozzle.

Further, this suppressor for suppressing exhaust gas can be provided at the outlet of the exhaust nozzle.

In addition, this suppressor is placed on the inner surface of the discharge port to increase the density by being compressed by the increase in the residual gas pressure, reduce the flow rate of the residual gas passing through per unit time, and coarsen the density by decreasing the residual gas pressure. It is possible to use one that increases the flow rate of residual gas passing through per unit time.

Further, the suppressor may be one that covers the discharge port with a covering.

Further, the suppressor for the exhaust suppressor may be inserted into the exhaust path of the driving needle to reduce the cross-sectional area through which the exhaust path can flow.

Further, it is preferable that a striking part for striking with a striking tool is formed at the upper end of the exhaust body.

Further, it is preferable that an engaging flange protrudes from the side surface of the driving needle, which engages with the wall surface of the aerosol container after driving into the aerosol container and prevents the needle from coming off.

Function Since the present invention is constructed as described above, in order to remove residual gas from a used aerosol container, hold the handle and bring the needle into contact with an appropriate position on the aerosol container. Drive the needle into the aerosol container and penetrate it. This driving can be done by holding the handle and hitting the driving needle strongly against the aerosol container, but it is better to form a hitting part on the upper end of the exhaust body and hitting this hitting part with a hammer or other striking tool. This is preferable.

When the handle is held by hand, the nozzle is located on the opposite side of the handle, so the nozzle does not face the operator, and residual gas, residual contents, etc. are sprayed towards the operator. This enables safe degassing work.

During this gas venting, if a suppressor for suppressing exhaust gas is provided in a part of the exhaust path from the outer surface of the opening of the driving needle to the outer surface of the discharge port of the exhaust nozzle, residual gas can be removed.
The jetting force of the residual contents is weakened, and they are not spread over a wide area, preventing contamination from spreading to the surrounding area, allowing for safe and clean degassing.

This suppressor is compressed by the increase in residual gas pressure to increase its density and reduce the flow rate of the residual gas passing through it per unit time. If you use a device with a configuration that increases the flow rate, even if the ejection pressure of residual gas changes, the amount of ejection per unit time will always be constant, and the residual gas and contents will not scatter over a wide range, resulting in stable operation. This enables safe injection.

In addition, if the suppressor is constructed of a cover that covers the discharge port, the injection pressure of the residual gas can be suppressed with a simple mechanism, so it is possible to prevent the residual gas, contents, etc. from scattering over a wide range with an inexpensive device. It is something.

In addition, if the suppressor for the exhaust suppressor is inserted into the exhaust path of the driving needle and the cross-sectional area of the exhaust path that can flow is reduced, there is no protrusion to the outside of the covering, etc., and operability is improved. It is good, and the external design is also favorable.

In addition, if an engaging flange is protruded from the side of the driving needle to engage with the aerosol container and prevent it from separating after driving into the aerosol container, the injection pressure of the residual gas that is injected will cause the driving needle to stick. This prevents the needle from flying out of the aerosol container and causing injury to the operator's face, etc., and allows for reliable discharge of residual gas.

Embodiment An embodiment of the present invention will be described below. Reference numeral 1 denotes an aerosol container, and an exhaust body is provided with a driving needle 2 for driving into and penetrating the aerosol container 1 at an appropriate position, which is made of hard resin, metal, etc. The aerosol container 1 protrudes from the lower end of the driving needle 3, and the side surface of the driving needle 2 is provided with an aerosol container 1.
Two engaging flanges 4 protrude to engage with the wall surface of the aerosol container 1 after being driven into the aerosol container 1 to prevent separation. Further, a handle 5 for holding by hand 11 is formed protrudingly on the side surface of the exhaust body 3, and an exhaust nozzle 6 is protruded from the side surface of the exhaust body 3 on the opposite side to the side on which the handle 5 is formed. 6 and the driving needle 2 are communicated through an exhaust passage 7 provided in the exhaust body 3. It is preferable to provide a suppressor 8 for suppressing exhaust gas in a part of the exhaust path 7 from the outer surface of the opening of the driving needle 2 to the outer surface of the discharge port 9 of the exhaust nozzle 6. The suppressor 8 for suppressing exhaust gas can be provided at the exhaust port 9 of the exhaust nozzle 6, and the suppressor 8 for suppressing exhaust gas is installed in the exhaust nozzle 6 as shown in FIGS. 2 and 3. The discharge port 9 is covered. This covering 8 expands with the exhausted residual gas and opens the exhaust port 9, preventing residual gas and residual contents from scattering over a wide range of rubber tubes, breathable non-woven fabrics, etc., and adjusting the flow rate. It is fine as long as it is possible. Further, at the upper end of the exhaust body 3, a striking portion 10 is formed for striking with a striking tool such as a hammer.

In the case configured as described above, in order to remove residual gas from the aerosol container 1 that has been used, hold the handle 5 and abut the driving needle 2 at an appropriate position on the aerosol container 1. 2 may be strongly struck against the aerosol container 1, but it is preferable to strike the striking portion 10 provided at the upper end of the exhaust body 3 with a striking tool such as a hammer. When the handle 5 is held by the hand 11, the exhaust nozzle 6 is located on the opposite side of the handle 5, as shown in FIG. There is no danger that the contents will be sprayed towards the worker, allowing safe degassing work.

During this degassing, a suppressor 8 for suppressing exhaust gas is installed at the discharge port 9 of the exhaust nozzle 6, so that the injection force of the residual gas and residual contents is weakened, and these are diffused over a wide area. Since there is no leakage or spreading of contamination to the surrounding area, it enables safe and clean gas removal.

The suppressor 8 may be simply formed from a rubber tube or the like as shown in FIGS. 2 and 3, but as shown in FIG. A flow rate regulator 13 is placed on the inner surface via a suitable elastic ring 12, and when the residual gas pressure is high, it is compressed, reducing the flow rate of pressurized fluid passing through per unit time, and when the residual gas pressure is low, the density is reduced. However, it is made of a material that increases the flow rate of residual gas passing through per unit time, such as wire mesh, sponge, and felt. One side of the flow rate regulator 13 is pressed by a piston 15 provided by connecting the communication passage 14 to the exhaust passage 7, and an opening 16 communicating with the communication passage 14 is connected to the piston 15 near the flow rate regulator 13. A flow rate regulating body 13 that is open on the side and presses residual gas or contents flowing out from this opening 16 with a piston 15.
Through the discharge port 9, the fluid can be discharged.

Furthermore, the suppressor 8 may be one in which an insert for suppressing exhaust gas is inserted into the exhaust path 7 of the driving needle 2 to suppress the amount of residual gas flowing out, without using the piston, covering, etc. good.

In addition, an engagement flange 4 protrudes from the side surface of the driving needle 2, which engages with the aerosol container 1 after driving into the aerosol container 1 and prevents it from coming off.
If the driving needle 2 is rotated half a turn after driving, the engaging flange 4
is caught on the inner surface of the aerosol container 1, and due to the injection pressure of the residual gas injected after injection,
This prevents the driving needle 2 from flying off from the aerosol container 1 and causing injury to the face, etc., and enables reliable discharge of residual gas.

Effects of the invention Since the invention is configured as described above, when the handle is held by hand, the nozzle is located on the opposite side of the handle, and the nozzle does not face the operator. Enables safe degassing of contents, etc.

In this gas venting, if a suppressor for suppressing exhaust gas is provided in a part of the exhaust path from the outer surface of the opening of the driving needle to the outer surface of the discharge port of the exhaust nozzle, residual gas can be removed.
The jetting power of the residual contents is weakened, preventing them from being spread over a wide area, allowing safe and clean degassing without spreading contamination of the surrounding area.

Furthermore, if this suppressor is configured by covering the discharge port with a covering such as a rubber tube, the injection pressure of the residual gas can be suppressed with a simple mechanism, so that the residual gas and contents can be suppressed with an inexpensive device. Prevents widespread scattering.

In addition, this suppressor is compressed by the increase in residual gas pressure to increase its density and reduce the flow rate of the residual gas passing through it per unit time. If you use a structure that increases the flow rate,
Even if the residual gas jetting pressure changes, the jetting amount per unit time is always constant, and the residual gas, contents, etc. do not scatter over a wide range, making stable and safe jetting possible.

Furthermore, if the suppressor for the exhaust suppressor is inserted into the exhaust path of the driving needle to reduce the cross-sectional area through which the exhaust path can flow, there will be no protrusion to the outside of the covering, and operability will be improved. It is good, and the external design is also favorable.

In addition, if an engaging flange is protruded from the side of the driving needle to engage with the aerosol container and prevent it from separating after driving into the aerosol container, the injection pressure of the residual gas that is injected will cause the driving needle to stick. This prevents the needle from flying out of the aerosol container and causing injury to the face, etc., and allows the residual gas to be discharged reliably.
