Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an aerosol can hole punching device for extracting contents such as residual gas in a can when disposing of various used aerosol cans and the like. In addition, the aerosol can according to the present invention, the contents of the liquefied gas in the can or the pressure of the compressed gas, the contents are discharged to the outside of the container through a valve by itself in the form of a mist or foam, the cassette It is assumed that the content in the can is divided into a gas phase and a liquid phase, such as a gas cylinder for a stove, from which gas is released to the outside.
[0002]
[Prior art]
[Patent Document 1] Japanese Utility Model Publication No. 7-43020
When discarding an aerosol can often used in general households after use, gas or the like is not completely discharged to the outside in the aerosol can, and is often discarded in a slightly remaining state.
[0004]
When disposing of the waste from these aerosol cans, there is a high risk of explosion due to residual gas, which is extremely dangerous for workers engaged in the work. When finished, it prompts the user to extract the remaining contents.
[0005]
Against this background, various devices and piers have been developed to pierce the aerosol can with a needle or the like in order to extract residual contents from the used aerosol can. If they are not safe and easy, there is no user cooperation.
[0006]
As an example, Japanese Utility Model Publication No. Hei 7-43020 discloses a V-shaped pedestal provided inside a container for accommodating an aerosol can, which seals the movement of the aerosol can at the time of drilling and determines the position thereof. A piercing device is shown in which a piercing needle is provided opposite to the base and the piercing needle is pierced into the aerosol can, or the aerosol can is pressed against the piercing needle to make a hole.
[0007]
In this piercing tool, since the V-shaped pedestal is used to determine the position of the aerosol can, the aerosol can of various sizes can be stably positioned. Further, a lid is provided on the container, and a V-shaped pedestal and a piercing needle are provided on the container bottom and the lid so as to face each other. When the hole is opened, the entire aerosol can can be stored inside the container. The residual contents of the aerosol can are prevented from flowing out of the container, thereby ensuring the safety of the boring operation.
[0008]
[Problems to be solved by the invention]
However, in the apparatus disclosed in Japanese Utility Model Publication No. 7-43020, in which the entire aerosol can is housed in the container to make a hole, the container needs to be large so as to be compatible with a large aerosol can which is commercially available. The punch itself becomes large, and the simplicity of the drilling operation is lost.
[0009]
There are many types of commercially available aerosol cans depending on the application such as paint and gas cylinders.In order to accommodate a part of the aerosol can and perform perforation as in the present invention, a large can inlet is provided in advance in the container. Although aerosol cans of different sizes are accommodated, it is not easy to regulate the excess opening of the can inlet according to the size of the aerosol can with a lid or the like, and the form thereof is not disclosed.
[0010]
In addition, when drilling a hole when not only gas but also a chemical solution remains in the aerosol can, the chemical solution etc. scatters inside the container, but there is no means to collect and discharge it. This is inconvenient, and the inside of the container is soiled, which causes a malfunction of the device.
[0011]
Furthermore, when the piercing needle is pierced into the aerosol can, a pierced needle with a round bar and a mere taper-shaped piercing tip goes beyond the tapered portion and pierces the aerosol can to a straight line portion. May come into contact with the edge of the hole of the aerosol can and become difficult to come off.
[0012]
Therefore, in the present invention, when a part of the aerosol can is inserted into the container to make a hole, the size of the aerosol can can be accommodated, and the inside of the container is sealed as much as possible to keep the residual contents of the aerosol can. An object of the present invention is to provide an aerosol can piercing device which is provided with a means for preventing an object from flowing out of a container and discharging residual contents, and which can perform easy and safe piercing.

Since only the conical taper portion 13c is pierced, there is no possibility that the perforating needle 13 pierces the aerosol can 30 more than necessary and does not become difficult to come off.
[0019]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. However, the following description is merely an exemplification of the present invention, and the technical scope of the present invention is not limited by the following description.
[0020]
FIG. 1 shows an aerosol can piercing device according to the present embodiment, which mainly includes a container 1, a slide cap 10 located above the container 1, and a bottom lid cap 20 serving as a tray member located below. . In the present embodiment, the purpose is to house and punch four types of aerosol cans 30 having diameters of about 70 mm, about 50 mm, about 40 mm, and about 25 mm, which are often used in ordinary households. It has a substantially cylindrical shape with a diameter of about 115 mm and a height of about 265 mm.
[0021]
The container 1 accommodates a part of the aerosol can 30 and performs perforation inside the container. The container 1 mainly includes a container main body 2, a receiving table 3, an upper partition plate 4, and a lower partition plate 5 therein. .
[0022]
The container body 2 is formed by winding a thin steel plate into a cylindrical shape, and joining the both ends in the winding direction to be welded. The cylindrical shape is substantially a perfect circle, the cylindrical axis is vertical, and a can inlet for inserting the lower part of the aerosol can 30 substantially perpendicularly to the center axis of the container body 2 on the circumferential side surface slightly below the middle. 2a is provided.
[0023]
In order to accommodate several types of aerosol cans having different diameters, the can inlet 2a of the container body 2 needs to be large enough to insert the largest aerosol can of the type of the target aerosol can. In this embodiment, the size of the can inlet 2a is approximately circular with a diameter of about 75 mm when viewed from the insertion direction of the aerosol can 30, so that the aerosol can 30 having a diameter of about 70 mm can be inserted.
[0024]
In the lower inside of the container main body 2, there is provided a receiving stand 3 for supporting the aerosol can 30 inserted from the can inlet 2a from below and determining the position. The cradle 3 is formed by bending a rectangular thin steel plate into a substantially V-shape. The V-groove extends in the direction of the center axis of the aerosol can, and is fixed by welding or the like so that the upper top portion is in contact with the inner diameter of the container body 2. .
[0025]
In addition, by making the receiving table 3 V-shaped, even aerosol cans having different diameters can be supported in contact at the inner valleys, and the positioning thereof becomes easy. When the receiver 3 is fixed inside the container body 2, the container body is slightly inclined in one of the V-groove directions so that the residual contents of the aerosol can 30 do not accumulate in the V groove of the receiver 3. It is desirable to fix to 2.
[0026]
An upper partition plate 4 and a lower partition plate 5 of a substantially circular steel plate corresponding to the inner diameter of the cylinder of the container main body 2 are provided in the upper part and near the middle of the container main body 2 respectively. In the vicinity of the center of the upper partition plate 4 and the lower partition plate 5, support holes 4a and 5a for vertically passing the puncture needle 13 are provided, and unnecessary play in the lateral direction of the puncture needle 13 is prevented to ensure the play. Be supportive.
[0027]
A slide cap 10 is provided above the container 1 so as to cover the cylindrical upper end.
The slide cap 10 mainly includes a cap tube 11, an upper lid 12, a piercing needle 13, and the like. The slide cap 10 slides up and down along the cylindrical central axis direction of the container 1, toward the aerosol tube 30 stored below the container 1. The perforating needle 13 inside the container 1 is lowered or raised.
[0028]
The cap tube 11 is a hard vinyl chloride tube having an inner diameter slightly larger than the outer diameter of the cylinder of the container main body 2, the center axis of which is vertical, and the upper end 12 of a circular thin steel plate adhered to the upper end so as to be horizontal. Then, the upper part of the container 1 is inserted from below.
[0029]
In the vicinity of the center of the lower surface of the circular upper lid 12, a vertical perforating needle 13 is provided to go downward. The perforating needle 13 is a thin circular steel bar whose upper end in the axial direction is welded to the upper lid 12, and the lower part passes through the support holes 4a and 5a provided in the upper partition plate 4 and the lower partition plate 5 of the container 1 as described above. So that the lower end thereof reaches slightly below the lower partition plate 5.
[0030]
A flat surface 13b perpendicular to the longitudinal direction is provided near the lower end, which is the end of the puncture needle 13 that pierces the aerosol tube 30, and a flat surface 13b is provided between the flat surface 13b and the tip of the puncture needle 13 rather than the flat surface 13b. A small bottom conical taper 13c is provided so that the top is the tip of the puncture needle 13 and is stepped.
[0031]
By making the vicinity of the distal end of the puncture needle 13 stepped in this manner, when the puncture needle 13 pierces the aerosol can 30, the flat surface 13b contacts the aerosol can 30 to prevent penetration and prevent the flat surface 13b from penetrating. Since only the conical tapered portion 13c at the tip of the surface 13c is pierced, the perforation needle 13 is prevented from being pierced into the aerosol can 30 more than necessary and hardly coming off.
[0032]
Further, in order to extract the remaining contents of the aerosol can 30, it is only necessary to make a small hole in the side surface of the aerosol can 30, and the height of the conical tapered portion 13c at the tip of the perforating needle 13 may be sufficient if it can penetrate the thickness of the side surface of the aerosol can 30. Increasing the height of the conical taper portion 13c and increasing its bottom portion may require useless force to penetrate the side surface of the aerosol can 30, increasing the cost of the perforating needle 13.
[0033]
Therefore, in this embodiment, it is assumed that the thickness of the commercially available aerosol can 30 is generally about 0.35 mm to 0.5 mm, and the height of the conical tapered portion 13 c of the perforating needle 13 is 0.5 mm to 10 mm. It is assumed that the following are appropriate lengths, the diameter of the straight portion 13a of the puncture needle 13 is 6 mm, the diameter of the bottom of the conical taper portion 13b is 2 mm, and the height of the conical taper portion 13b is 3 mm.
[0034]
Inside the container 1 separated by the upper partition plate 4 and the lower partition plate 5, a stopper 14 fixed to a predetermined position of the perforating needle 13, and a vertical compression spring between the stopper 14 and the lower partition plate 5. 15 are provided. The stopper 14 is a metal pipe having a vertical axis. A horizontal portion is provided inside the upper portion of the stopper 14 through which the needle 13 passes, and a compression spring 15 is inserted from below the stopper 14 to the lower surface of the horizontal portion. I do.
[0035]
When the perforating needle 13 slides up and down while being supported by the support holes 4a and 5a of the upper partition plate 4 and the lower partition plate 5, the upper end of the stopper 14 fixed to a predetermined position of the perforating needle 13 is placed on the upper partition plate. The lower end of the stopper 14 contacts the upper surface of the lower partition plate 5 and serves as the lower end of the slide.
[0036]
In the above configuration, the slide cap 10 slides up and down so that the support holes 4 a and 5 a of the upper partition plate 4 and the lower partition plate 5 serve as guides for the puncture needle 13 and cover the upper part of the container 1. . The slide cap 10 is always positioned at the upper end of the slide by the reaction force of the stopper 14 and the compression spring 15 provided inside the container 1 and separated by the upper partition plate 4 and the lower partition plate 5. . That is, when the upper surface of the upper lid 12 at the upper end of the slide cap 10 is pushed downward, the perforation needle 13 inside the container 1 is lowered, and when released, the slide cap 10 returns to the original position and the perforation needle 13 rises. Become.
[0037]
Further, since the upper and lower ends of the slide of the slide cap 10 are determined by the stoppers 14 provided at the upper end of the compression spring 15, the slide cap 10 does not unnecessarily descend, but rises and the slide cap 10 is It does not come off.
[0038]
On the other hand, a bottom cover cap 20 as a pan member provided below the container 1 mainly includes a regulating ring 21, a bottom tube 23, and a bottom cover 23.
[0039]
The restricting ring 21 is formed by winding a thin steel plate into a cylindrical shape in the same manner as the container main body 2, and joining the both ends in the winding direction and welding them. Keep it slightly larger. Therefore, when the regulating ring 21 is fitted into the container 1 so that the center axis thereof coincides with the container 1, the regulating ring 21 can freely rotate around the outer circumference of the container 1.
[0040]
Openings 22 a, 22 b, 22 c, and 22 d are provided on the circumferential side surface of the regulating ring 21 at predetermined intervals as a plurality of openings 22 having different sizes corresponding to several types of aerosol cans 30 having different diameters. The openings 22a, 22b, 22c, and 22d are positioned so that when the regulating ring 21 is rotated outside the circumference of the container 1, the openings 22a, 22b, 22c, and 22d respectively overlap the can inlets 2a of the container 1, and the lower ends thereof coincide with each other. Let it. In other words, when the regulating ring 21 is slightly rotated to the right when viewed from below when the opening 22a of the regulating ring 21 overlaps, the opening 22b overlaps the can inlet 2a so that the lower end thereof coincides, Further rotation causes the openings 22c and 22d to sequentially overlap the can inlet 2a in the same manner.
[0041]
The openings 22 a, 22 b, 22 c, and 22 d are set to have a minimum size necessary for inserting the aerosol can 30 adapted to each of them substantially perpendicularly to the central axis direction of the regulating ring 21.
[0042]
With the above configuration, the can inlet 2a can be sequentially changed in size as viewed from the outside by the regulating ring 21 provided on the outside of the container 1, and the aerosol can 30 can be any one of the openings 22a, 22b, 22c, and 22d. The heel is inserted through the can inlet 2a, and is supported by the receiving table 3 inside the container 1. Furthermore, when the aerosol can 30 is accommodated in the container 1, an extra opening between the can inlet 2a and the aerosol can 30 is closed by the restriction ring 21, so that the airtightness inside the container 1 can be improved. .
[0043]
In the regulation ring 21 of the present embodiment, an opening 22a corresponding to the target aerosol can having a diameter of about 70 mm is provided, and an opening 22b corresponding to an aerosol can having a diameter of about 50 mm is provided next to the opening 22b. An opening 22c corresponding to an aerosol can having a diameter of about 40 mm and an opening 22d corresponding to an aerosol can having a diameter of about 25 mm were sequentially provided next to the opening 22c.
[0044]
Below the regulating ring 21, a bottom pipe 23 of a hard vinyl chloride pipe is fitted and bonded to the outside, and a bottom lid 24 made of a horizontal circular steel plate is bonded to a lower end of the bottom pipe 23.
[0045]
As shown in FIG. 8, the bottom cover cap 20 as a receiving member constitutes a receiving container having the bottom cover 24 as a bottom by a regulating ring 21, a bottom tube 23 and a bottom cover 24, and the regulating ring 21 is accommodated. Since the bottom cover cap 20 as a pan member can be freely pulled out from the container 1 because it is merely fitted into the outside of the container 1 from below. Therefore, the residual contents of the aerosol tube 30 scattered inside the container 1 flow down due to gravity and accumulate inside the bottom cover cap 20 as a receiving member, but the bottom cover cap 20 as a receiving member is removed from the container 1. The accumulated residual contents can be easily disposed of.
[0046]
Next, as an example, a method of using the aerosol can piercing device of the present invention when piercing the aerosol can 30 having a can body 30a having a diameter of 65 mm will be described together with its operation.
[0047]
The general aerosol can 30 mainly has a cylindrical shape with a vertical central axis and includes a can 30a in which a chemical solution or a propellant is sealed, and an injection nozzle 30b for injecting the contents of the can 30a above the can 30a.
[0048]
First, the aerosol can piercing device of the present invention is placed on a horizontal floor or the like, and the restricting ring 21 overlapping the can inlet 2a of the container 1 is previously rotated to control the aerosol can having a diameter of about 70 mm. The opening 22a of 21 is made to overlap the can inlet 2a.
[0049]
Then, as shown in FIG. 1, the aerosol can 30 is turned sideways in the direction of the arrow, and inserted into the opening 22a from the bottom side of the can 30a. The aerosol can 30 is inserted until its bottom comes into contact with the inner wall at the back of the can inlet 2a of the container 1, and is placed in the V-groove of the receiving table 3 inside the container 1.
[0050]
Next, when the upper lid 12 which is the upper end surface of the slide cap 10 is pressed down with a foot or the like, the perforation needle 13 vertically located above the aerosol can 30 in the container 1 is lowered, and the cone at the lower end of the perforation needle 13 is formed. The tapered portion 13c pierces the can 30a of the aerosol can 30.
[0051]
The operation of pushing down the slide cap 10 can be easily carried out by hand if the compression spring 15 inside the container 1 is soft and the aerosol can has a small thickness. If the punching device is placed on the floor and the slide cap 10 is pressed down with the foot, no force is required, and the drilling operation can be performed with ease.
[0052]
As soon as the perforating needle 13 pierces the aerosol can 30, residual contents such as gas are ejected from the hole, but as described above, the extra opening of the can inlet 2 a of the container 1 with the aerosol can 30 is restricted by the restriction ring. Since the closed contents are restricted by the opening 22a of the aerosol can 21, the residual contents of the jetted aerosol can 30 do not flow out of the container 1 in large quantities.
[0053]
When the aerosol can 30 is perforated and the slide cap 10 that has been pushed down is released, the slide cap 10 is raised to the original position by the reaction force of the stopper 14 and the compression spring 15 provided inside the container 1, and the container 1 The inner puncture needle 13 will also rise.
[0054]
If the liquid residual contents are scattered inside the container 1 when the aerosol can 30 is opened, the residual contents are scattered by gravity in the bottom lid cap 20 as a pan member below the container 1. Therefore, the bottom cap 20 serving as a receiving member may be withdrawn from the container 1 and the remaining contents may be discarded, and the cleaning and the like are easy.
[0055]
Further, in the above description, an example was shown in which a hole is formed in the aerosol can 30 in which the diameter of the can 30a is 65 mm. However, in order to form a hole in an aerosol can having a diameter of 50 mm or 40 mm, the regulation ring 21 is rotated. By moving it, the one having the size closest to the diameter of the can is selected from the openings 22a, 22b, 22c, and 22d so as to overlap the can inlet 2a of the container 1, and if the hole drilling operation is performed in the above procedure, Good.
[0056]
The present invention is not limited to the above embodiment, and various changes can be made within the scope of the gist. For example, four rings 22a, 22b, 22c, and 22d are provided in the regulating ring 21 for the purpose of accommodating and drilling four types of aerosol cans 30 having diameters of about 70 mm, about 50 mm, about 40 mm, and about 25 mm. Although the above example has been described, the types of the openings 22 may be increased by increasing the cylindrical diameters of the container 1 and the regulating ring 21 or the types of the aerosol cans 30 to be perforated by reducing the number may be narrowed down.
[0057]
Also, an example is shown in which the aerosol can 30 inserted from the can inlet 2a of the container 1 is supported from below by the V-shaped pedestal 3, but the can inlet 2a penetrates in a direction perpendicular to the central axis of the container 1. Similarly, the regulating ring 21 is also provided so as to penetrate in a direction perpendicular to the central axis and through an opening 22 corresponding to the diameter of the aerosol can 30 so as to overlap with the can inlet 2a. The can inlet 2a and the opening 22 may be inserted and supported.
[0058]
The opening 22 corresponding to the aerosol cans of different sizes provided in the regulating ring 21 needs to be slightly larger than the diameter thereof in order to insert the aerosol can 30, and the gap between the can body 30a of the aerosol can 30 and the opening 22 is required. Is difficult to eliminate completely. However, a packing such as a sponge may be provided at the edge of the opening 22 of the regulating ring 21 so as to increase the hermeticity inside the container 1.
[0059]
In order to provide a perforating device at low cost, an example was shown in which the container body 2 and the regulating ring 21 were made of a thin steel plate, and the cap tube 11 and the bottom tube 23 were made of a hard vinyl chloride tube. The bottom cover cap 20 serving as a pan member and the components of the container 1 may be made of an integrated plastic, resin, or the like. If the container 1 is made of transparent resin, The interior can be seen to give the user a sense of security, and the design can be excellent.
[0060]

A plurality of openings having different sizes are provided on the side surface of the regulating ring, and the size of the opening is the same as or smaller than the size of the can inlet of the container, and the size of the can inlet of the container is reduced. It is possible to regulate by the opening of the regulating ring, aerosol cans of different sizes can be fixedly inserted in the predetermined position of the container, and the extra opening of the container inlet of the container can be made even when drilling holes. By restricting, it is possible to prevent a large amount of residual contents from flowing out of the container. Therefore, it is possible to prevent the surroundings from being soiled at the time of drilling, and to safely perform the drilling operation of the aerosol can.
[0061]
According to the invention of claim 2, both ends of the container in the direction of the central axis of the cylinder are located vertically, and the container is provided with a detachable pan member covering the lower end thereof, and the pan member is removed.
