Description

    This device relates to a device for collecting and collecting contents of a spray can.

The conventional methods for discharging and collecting residual liquid and residual gas such as paint and insecticide remaining in spray cans differ between processing specialists and general users. They are processing specialists that use large devices such as Patent Publication 2003-340310 and Patent Publication 2003-161594, and cases where they are processed in large quantities, and use simple jigs like ordinary users. There are two cases. The former apparatus is suitable for mass processing of hundreds to thousands, and the latter processes one by one. In order for the general user to use the jig for processing, it is necessary to continue spraying the residual liquid, which is the contents of the spray can, until it disappears on the newspaper or waste cloth, and then use the jig after confirming that the contents are gone. It was. These jigs include, for example, a registered utility model No. 3098232 spray can drilling tool and Japanese Patent Publication No. 2000-177786 degassing caps, which discharge residual gas one by one. Another method is to carefully open a small hole with a nail or the like in the upper part of the container of the remaining spray can, and then open the can with a can opener to remove the residual liquid. If the door is opened, there is a danger that the residual liquid will erupt vigorously. For those using simple jigs as described above, it takes a long time until the gas pressure drops, and it is inconvenient and dangerous because the contents cannot be taken out without confirming that the gas pressure has dropped. It was a thing.
In addition to the large-scale equipment used by specialized processors, the simple equipment and treatment that can process all cans and spray cans with the contents as in the present invention in a short time without being aware of the remaining amount of residual liquid. There were no ingredients. The spray can contents discharge and recovery device of the present invention is suitable for processing several to several tens of treatments at one time, and industrially uses spray cans such as paints mainly in paint factories. Can be used in the workplace. There are no conventional degassing jigs or devices suitable for processing several to several tens of pieces, and an inexpensive and simple device such as the spray can contents discharge and recovery device of the present invention is desired. It was.

The following is a simple and safe method for discharging and collecting the residual liquid and remaining gas in the spray can.
(1) By simply dropping the spray can into the spray can contents discharging and collecting device, a hole is opened in the bottom of the spray can in the device, and the remaining liquid can be safely discharged and recovered without releasing the residual liquid outside the device. Can do.
(2) The device is small enough to be carried and can be easily used by anyone at the work site without requiring large equipment.
(3) When processing using the conventional method, it is necessary to continue spraying until there is no content in the newspaper or waste cloth, and after confirming that there is almost no residual liquid, it is necessary to attach a gas vent cap or spray can punch. However, the remaining spray can can be put into the spray can contents discharging and collecting apparatus as it is, and the processing time is instantaneous and the time required for the work can be shortened.

In order to solve the above problems, the present invention is summarized as follows.
(1) A) Discharge of spray can with a container having a circular cylindrical wall that is slightly larger than the spray can, and B) a needle-like body with a sharp tip provided so as to hit the center of the bottom of the spray can container It is a recovery device.
(2) The gap between the circular cylindrical wall of A) and the spray can is adjusted so as to secure an outlet for residual gas and prevent the residual liquid from being discharged out of the apparatus, and the residual liquid can be stored in the apparatus. It is the spray can contents discharge collection device constituted as mentioned above.
(3) B) Spray can in which the tip of a needle-like body capable of making a hole in the center of the bottom of the spray can container has a maximum diameter of 1.5 mm or less and a pointed needle-like body fixed to the center of the bottom. It is a contents discharge collection device.
(4) The circular cylindrical wall has a gap of 2 to 10 mm between it and the spray can, and is within 30 to 50 mm from the lower end of the circular cylindrical wall to the position of the pointed end of the needle-like body. Item 4. The spray can content discharge and recovery device according to any one of Items 1 to 3.

    According to the present invention, unlike the above-described gas vent cap and spray can hole punch, it can be processed without checking the remaining amount of the spray can, and it is safe without the residual liquid being discharged outside the apparatus. . There is no need for electricity or air, and it is easy to carry around when using a large device. The cost of the spray can contents discharge and collection device is slightly higher than the degassing cap and spray can hole punch, etc., but it is 1/100 compared to the large-scale devices and large-scale automatic devices used by disposal specialists. It is a low-priced product of about 1/1000, and the processing time is about 10 to 60 seconds per can, which is equivalent to a large apparatus. In addition, there is no need for maintenance as in the case of large-sized devices, and no running cost is required.

Embodiments of the present invention will be described in detail below.
1) The device of claim 1 comprises: A) a container having a circular cylindrical wall that is slightly larger than the spray can; and B) a needle-like body having a sharp tip provided so as to contact the center of the bottom of the spray can container. The gist of the spray can contents discharge and recovery device provided. A) A container having a circular cylindrical wall that is one size larger than a spray can has a cylindrical portion that is slightly wider than the spray can on the top plate of a 4L capacity, for example, a tin can, for example, a quarter liter. It is a container with a built-in round can. The circular cylindrical wall is slightly wider than the spray can so that there is no gap in the spray can being inserted vertically. At the same time, when the spray can is introduced, residual liquid and residual gas are ejected all at once. In addition, it is effective as means for discharging only residual gas to the outside through the gap between the spray can and the circular cylindrical wall. B) There is no problem if you can make a hole in the bottom center of the spray can container, as long as it is a nail or needle-like one with a sharp tip, and fix it vertically to the bottom of the spray can contents discharge and collection device The purpose can be obtained. The fixing position needs to be fixed at a position corresponding to the center of the bottom of the spray can to be charged.

    2) The invention of claim 2 is such that the gap between the circular cylindrical wall of A) and the spray can is adjusted so as to secure an outlet for residual gas and prevent the residual liquid from coming out of the apparatus. The gist of the spray can content discharge and recovery device is configured to be able to store. As described above, the gist of the present invention is that the bottom structure of the spray can has an arc-shaped concave shape, and by making a hole in the center of the bottom of the spray can, the ejection of residual liquid and residual gas is almost from the bottom of the container. It can be ejected vertically underneath. Even if there is a residual liquid that bounces, the residual liquid does not rise in a slight gap between the spray can and the circular cylindrical wall, and the residual liquid does not come out of the apparatus. Therefore, only residual gas is released to the outside. The reason why the gap between the circular cylindrical wall of the present invention and the spray can is slightly opened is to store only the residual liquid at the bottom of the apparatus.

    3) The invention of claim 3 is characterized in that the bottom of the needle-like body with the tip having a maximum diameter of 1.5 mm or less at the tip of the needle-like body capable of making a hole in the center of the bottom of the spray can container. The gist of the spray can contents discharge collection device fixed in the center. When a spray can is put into the spray can contents discharge and collection device, a needle-like body with a sharp tip hits a hole at the bottom of the spray can. Slightly different. The reason why the diameter of the tip of the needle-like body having a sharp tip is 1.5 mm or less is that if a large hole of 1.5 mm or more is opened, the residual liquid and the residual gas will jump out vigorously. In this case, the residual gas cannot be released gently only by the gap between the circular cylindrical wall and the spray can, and there is a risk that the residual liquid may also be released outside the device. Is. If the diameter of the tip of the needle-shaped body is 1.5 mm or less, even if the gap between the circular cylindrical wall and the spray can is 2 mm, the residual liquid will not be discharged outside the device and it will be safely discharged. Collection processing is possible.

    4) The invention of claim 4 is such that the circular cylindrical wall is provided with a gap of 2 to 10 mm between the spray can and the position of the lower end of the circular cylindrical wall and the tip of the sharp needle-like body is 30. It is within 50 mm. The gist of the spray can content discharging and collecting apparatus according to claim 1. The width of the gap between the circular cylindrical wall and the spray can is important. When the gap is 2 mm or less, when the spray can is put in, it easily comes into contact with the circular cylindrical wall and does not drop smoothly, and a predetermined hole is made. I can't. If it exceeds 10 mm, the spray can does not fall vertically but falls diagonally and a hole cannot be made in the center of the bottom of the spray can, and the residual liquid and residual gas are ejected at an oblique angle. As a result, rebound increases and the residual liquid may spout out of the apparatus beyond the circular cylindrical wall. As a result of repeated experimentation of the charging process, it is preferable that the gap that allows the smoothest charging and prevents the residual liquid to be ejected outside the apparatus is in the range of 3 to 6 mm. In addition, the depth of the circular cylindrical wall needs to be 30 to 50 mm or less from the lower end of the wall to the uppermost position of the needle-like body having a sharp tip. If it is more than 50 mm, the spray can tilts slightly, and a hole cannot be made in the center of the bottom of the spray can, and similarly, residual liquid and residual gas are ejected at an oblique angle. In the case of 30 mm or less, when the number of treatments is increased, the residual liquid is accumulated in the apparatus, and the liquid level approaches the tip of the needle-like body. Then, it is not preferable because the liquid surface is easily shaken and scattered under the influence of the ejection of the residual liquid and the residual gas, and the residual liquid is ejected outside the apparatus. Next, the length in the height direction of the circular cylindrical wall is shorter than the height of the spray can, and the upper part of the charged spray can protrudes about 10 to 50 mm from the top of the spray can contents discharge and recovery device. , It becomes easy to take out an empty spray can after processing, and workability is improved.

    Below, the punching type spray can content discharge | emission collection | recovery apparatus of this invention and the discharge | emission method using the same are demonstrated based on an Example. There are two types of paint spray cans that are widely available on the market: 300 ml cans and 430 ml cans. As for the contents, the spray can with the ratio of paint and spray gas is mainly 1: 1. The 300ml spray can has 150ml paint and 150ml propellant, and the latter 430ml spray can has 215ml paint. The propellant is 215 ml. Therefore, if 10 cans of new or nearly all remaining spray cans are treated, a maximum of 1.5 l to 2.15 l of paint can be recovered. If the size of the spray can contents discharge and recovery device is approximately 4 to 6 L in capacity, about 2.5 L of residual liquid can be recovered. It is also possible to install a plurality of circular cylindrical walls in the spray can contents discharge and collection device, and it is possible to process a plurality of sprays at the same time, thereby improving workability. In this case, it is necessary to increase the capacity by 4 to 6 L or more. Next, the normal paint spray can has a height of 60 mm and a height of 140 mm for a 300 ml capacity can, and a height of 157 mm for a 430 ml capacity of the same 430 ml can. Therefore, the height of the circular cylindrical wall of the spray can contents discharge and collection device is 30-50 mm shorter than the height of the spray can 140 mm to 157 mm, and when the height is about 110 to 127 mm, the spray can is about 10 to 50 mm higher. Thus, it becomes easier to take out the empty spray can after the processing is completed, and the workability is improved. Since the various spray cans other than the paint have different diameters and heights, it is one method to make a slide structure so that the height and diameter of the circular cylindrical wall can be arbitrarily changed. For example, to adjust the height of a circular cylindrical wall, there is a method of sliding two cylinders. To change the diameter of the cylindrical wall, cut one side in the direction of the height of the cylindrical wall and wind it up. If the structure can be changed to a diameter by entraining, it becomes possible to cope with spray cans of various shapes.

    An embodiment of the invention will be described with reference to the drawings. FIG. 1 is a schematic perspective view of a spray can contents discharging and collecting apparatus according to the present invention, FIG. 2 is an end view of a circular cylindrical wall and needle-like body of the spray can contents discharging and collecting apparatus, and FIG. 3 is a plan view. .

    The spray can contents discharging and collecting apparatus of the present invention is constructed by integrating the needle can 4 into the spray can inlet 8, the circular cylindrical wall 2 and the bottom of the apparatus shown in FIG. The needle-shaped body is made of metal, but the others may be made of synthetic resin such as PP / PE.

    The needle-like body 4 of the spray can content discharging and collecting apparatus shown in FIG. 3 is supported by a reinforcement 7 so as not to fall down and is fixed to the bottom.

    FIG. 4 is a schematic diagram showing a state immediately before the spray can is dropped into the spray can contents discharging and collecting apparatus. When the spray can 9 is dropped into the inlet 8 that is opened slightly wider than the spray can, the needle-like body 4 is pierced in the center of the bottom of the spray can, so that a hole can be surely formed.

    The needle-like body 4 in FIG. 3 is made of a steel rod having a diameter of 2 to 5 mm, and the tip portion 5 is sharply sharpened between 2 to 5 mm from the front end and processed to a maximum diameter of 1.5 mm. 5 is provided.

    FIG. 5 is a schematic view for explaining a state in which the spray can is dropped into the spray can contents discharging and collecting apparatus of the present invention, the hole 13 is opened in the center of the bottom of the can, and the residual liquid and the residual gas 14 are ejected. is there. When a spray can is inserted, it falls smoothly vertically by a circular cylindrical wall and an appropriate gap, a hole is opened in the center of the bottom of the circular arc shape of the bottom, residual liquid remains in the device, and only the residual gas is released outside the device I understand.

    It is preferable that the discharge port 6 of the spray can contents discharging and collecting apparatus of the present invention is attached to the upper part as much as possible. If the spray can is continuously treated, the residual liquid will remain in the apparatus, and the residual liquid must be discharged out of the apparatus before the tip of the needle-like body is filled with the residual liquid. If necessary, the spray can can be treated in an open state. In this case, the remaining gas can be discharged out of the apparatus more smoothly.

    As a safety measure, it is recommended that the spray can contents collection / recovery device of the present invention be attached to a ground wire while paying attention to fire in a well-ventilated area.

    Multiple processes, such as spray cans with a large amount of residual liquid and 10 or more at a time, which were difficult to process with conventional degassing caps such as degassing caps and spray can drilling tools, can be handled safely and easily. This is a spray can content discharge and recovery device that can easily recover the residual liquid of waste spray cans that are generated in large numbers in paint factories that consume a relatively large amount of spray cans, such as automobile repair paint factories. .

    This device relates to a device for collecting and collecting contents of a spray can.

    The conventional methods for discharging and collecting residual liquid and residual gas such as paint and insecticide remaining in spray cans differ between processing specialists and general users. They are processing specialists that use large devices such as Patent Publication 2003-340310 and Patent Publication 2003-161594, and cases where they are processed in large quantities, and use simple jigs like ordinary users. There are two cases. The former apparatus is suitable for mass processing of hundreds to thousands, and the latter processes one by one.

JP2003-340310 JP2003-161594

In order for the general user to use the jig for processing, it is necessary to continue spraying the residual liquid, which is the contents of the spray can, until it disappears on the newspaper or waste cloth, and then use the jig after confirming that the contents are gone. It was. These jigs include, for example, a registered utility model No. 3098232 spray can drilling tool and Japanese Patent Publication No. 2000-177786 degassing caps, which discharge residual gas one by one. Another method is to carefully open a small hole with a nail or the like in the upper part of the container of the remaining spray can, and then open the can with a can opener to remove the residual liquid. If the door is opened, there is a danger that the residual liquid will erupt vigorously. For those using simple jigs as described above, it takes a long time until the gas pressure drops, and it is inconvenient and dangerous because the contents cannot be taken out without confirming that the gas pressure has dropped. It was a thing.

In addition to the large-scale equipment used by specialized processors, the simple equipment and treatment that can process all cans and spray cans with the contents as in the present invention in a short time without being aware of the remaining amount of residual liquid. There were no ingredients. The spray can contents discharge and recovery device of the present invention is suitable for processing several to several tens of treatments at one time, and industrially uses spray cans such as paints mainly in paint factories. Can be used in the workplace. There are no conventional degassing jigs or devices suitable for processing several to several tens of pieces, and an inexpensive and simple device such as the spray can contents discharge and recovery device of the present invention is desired. It was.
The following is a simple and safe method for discharging and collecting the residual liquid and remaining gas in the spray can.
(1) By simply dropping the spray can into the spray can contents discharging and collecting device, a hole is opened in the bottom of the spray can in the device, and the remaining liquid can be safely discharged and recovered without releasing the residual liquid outside the device. Can do.
(2) The device is small enough to be carried and can be easily used by anyone at the work site without requiring large equipment.
(3) When processing using the conventional method, it is necessary to continue spraying until there is no content in the newspaper or waste cloth, and after confirming that there is almost no residual liquid, it is necessary to attach a gas vent cap or spray can punch. However, the remaining spray can can be put into the spray can contents discharging and collecting apparatus as it is, and the processing time is instantaneous and the time required for the work can be shortened.

In order to solve the above problems, the present invention is summarized as follows.
(1) A) Discharge of spray can with a container having a circular cylindrical wall that is slightly larger than the spray can, and B) a needle-like body with a sharp tip provided so as to hit the center of the bottom of the spray can container It is a recovery device.
(2) The clearance between the circular cylindrical wall of the container A) having a circular cylindrical wall that is slightly larger than the spray can and the spray can are adjusted so as to secure a residual gas outlet and prevent the residual liquid from exiting the apparatus. The apparatus for discharging and collecting contents of a spray can according to claim 1, wherein the apparatus is configured so that residual liquid can be stored in the apparatus.
(3) The tip of the needle-like body B) having a sharp tip provided so as to hit the center of the spray can container bottom is made to have a maximum diameter of 1.5 mm or less. It is a spray can content discharge collection device of description.
(4) The circular cylindrical wall has a gap of 2 to 10 mm between the spray can and within 30 to 50 mm from the lower end of the circular cylindrical wall to the position of the tip of the sharp needle-shaped body. It is a spray can content discharge | emission collection | recovery apparatus in any one of Claims 1-3.

    According to the present invention, unlike the above-described gas vent cap and spray can hole punch, it can be processed without checking the remaining amount of the spray can, and it is safe without the residual liquid being discharged outside the apparatus. . There is no need for electricity or air, and it is easy to carry around when using a large device. The cost of the spray can contents discharge and collection device is slightly higher than the degassing cap and spray can hole punch, etc., but it is 1/100 compared to the large-scale devices and large-scale automatic devices used by disposal specialists. It is a low-priced product of about 1/1000, and the processing time is about 10 to 60 seconds per can, which is equivalent to a large apparatus. In addition, there is no need for maintenance as in the case of large-sized devices, and no running cost is required.

Embodiments of the present invention will be described in detail below.
1) The device of claim 1 comprises: A) a container having a circular cylindrical wall that is slightly larger than the spray can; and B) a needle-like body having a sharp tip provided so as to contact the center of the bottom of the spray can container. The gist of the spray can contents discharge and recovery device provided. A) A container having a circular cylindrical wall that is one size larger than a spray can has a cylindrical portion that is slightly wider than the spray can on the top plate of a 4L capacity, for example, a tin can, for example, a quarter liter. It is a container with a built-in round can. The circular cylindrical wall is slightly wider than the spray can so that there is no gap in the spray can being inserted vertically. At the same time, when the spray can is introduced, residual liquid and residual gas are ejected all at once. In addition, it is effective as means for discharging only residual gas to the outside through the gap between the spray can and the circular cylindrical wall. B) There is no problem if you can make a hole in the bottom center of the spray can container, as long as it is a nail or needle-like one with a sharp tip, and fix it vertically to the bottom of the spray can contents discharge and collection device The purpose can be obtained. The fixing position needs to be fixed at a position corresponding to the center of the bottom of the spray can to be charged.

2) The invention of claim 2 is such that the gap between the circular cylindrical wall of A) and the spray can is adjusted so as to secure an outlet for residual gas and prevent the residual liquid from coming out of the apparatus. The gist of the spray can content discharge and recovery device is configured to be able to store. As described above, the gist of the present invention is that the bottom structure of the spray can has an arc-shaped concave shape, and by making a hole in the center of the bottom of the spray can, the ejection of residual liquid and residual gas is almost from the bottom of the container. It can be ejected vertically underneath. Even if there is a residual liquid that bounces, the residual liquid does not rise in a slight gap between the spray can and the circular cylindrical wall, and the residual liquid does not come out of the apparatus.
Therefore, only residual gas is released to the outside. The reason why the gap between the circular cylindrical wall of the present invention and the spray can is slightly opened is to store only the residual liquid at the bottom of the apparatus.

3) The invention of claim 3 is characterized in that the bottom of the needle-like body with the tip having a maximum diameter of 1.5 mm or less at the tip of the needle-like body capable of making a hole in the center of the bottom of the spray can container. The gist of the spray can contents discharge collection device fixed in the center. When a spray can is put into the spray can contents discharge and collection device, a needle-like body with a sharp tip hits a hole at the bottom of the spray can. Slightly different. The reason why the diameter of the tip of the needle-like body having a sharp tip is 1.5 mm or less is that if a large hole of 1.5 mm or more is opened, the residual liquid and the residual gas will jump out vigorously. In this case, the residual gas cannot be released gently only by the gap between the circular cylindrical wall and the spray can, and there is a risk that the residual liquid may also be released outside the device. Is.
If the diameter of the tip of the needle-shaped body is 1.5 mm or less, even if the gap between the circular cylindrical wall and the spray can is 2 mm, the residual liquid will not be discharged outside the device and it will be safely discharged. Collection processing is possible.

4) The invention of claim 4 is such that the circular cylindrical wall is provided with a gap of 2 to 10 mm between the spray can and the position of the lower end of the circular cylindrical wall and the tip of the sharp needle-like body is 30. It is within 50 mm. The gist of the spray can content discharging and collecting apparatus according to claim 1. The width of the gap between the circular cylindrical wall and the spray can is important. When the gap is 2 mm or less, when the spray can is put in, it easily comes into contact with the circular cylindrical wall and does not drop smoothly, and a predetermined hole is made. I can't. If it exceeds 10 mm, the spray can does not fall vertically but falls diagonally and a hole cannot be made in the center of the bottom of the spray can, and the residual liquid and residual gas are ejected at an oblique angle. As a result, rebound increases and the residual liquid may spout out of the apparatus beyond the circular cylindrical wall. As a result of repeated experimentation of the charging process, it is preferable that the gap that allows the smoothest charging and prevents the residual liquid to be ejected outside the apparatus is in the range of 3 to 6 mm. In addition, the depth of the circular cylindrical wall needs to be 30 to 50 mm or less from the lower end of the wall to the uppermost position of the needle-like body having a sharp tip. If it is more than 50 mm, the spray can tilts slightly, and a hole cannot be made in the center of the bottom of the spray can, and similarly, residual liquid and residual gas are ejected at an oblique angle. In the case of 30 mm or less, when the number of treatments is increased, the residual liquid is accumulated in the apparatus, and the liquid level approaches the tip of the needle-like body. Then, it is not preferable because the liquid surface is easily shaken and scattered under the influence of the ejection of the residual liquid and the residual gas, and the residual liquid is ejected outside the apparatus. Next, the length in the height direction of the circular cylindrical wall is shorter than the height of the spray can, and the upper part of the charged spray can protrudes about 10 to 50 mm from the top of the spray can contents discharge and recovery device. , It becomes easy to take out an empty spray can after processing, and workability is improved.

Below, the punching type spray can content discharge | emission collection | recovery apparatus of this invention and the discharge | emission method using the same are demonstrated based on an Example. There are two types of paint spray cans that are widely available on the market: 300 ml cans and 430 ml cans. As for the contents, the spray can with the ratio of paint and spray gas is mainly 1: 1. The 300ml spray can has 150ml paint and 150ml propellant, and the latter 430ml spray can has 215ml paint. The propellant is 215 ml. Therefore, if 10 cans of new or nearly all remaining spray cans are treated, a maximum of 1.5 l to 2.15 l of paint can be recovered. If the size of the spray can contents discharge and recovery device is approximately 4 to 6 L in capacity, about 2.5 L of residual liquid can be recovered. It is also possible to install a plurality of circular cylindrical walls in the spray can contents discharge and collection device, and it is possible to process a plurality of sprays at the same time, thereby improving workability. In this case, it is necessary to increase the capacity by 4 to 6 L or more. Next, the normal paint spray can has a height of 60 mm and a height of 140 mm for a 300 ml capacity can, and a height of 157 mm for a 430 ml capacity of the same 430 ml can. Therefore, the height of the circular cylindrical wall of the spray can contents discharge and collection device is 30-50 mm shorter than the height of the spray can 140 mm to 157 mm, and when the height is about 110 to 127 mm, the spray can is about 10 to 50 mm higher. Thus, it becomes easier to take out the empty spray can after the processing is completed, and the workability is improved. Since the various spray cans other than the paint have different diameters and heights, it is one method to make a slide structure so that the height and diameter of the circular cylindrical wall can be arbitrarily changed. For example, to adjust the height of a circular cylindrical wall, there is a method of sliding two cylinders. To change the diameter of the cylindrical wall, cut one side in the direction of the height of the cylindrical wall and wind it up. If the structure can be changed to a diameter by entraining, it becomes possible to cope with spray cans of various shapes.
