It is stored in a closed state. Then, when the extension tube 200 is taken out from the internal space S, the end portion of the extension tube 200 is pulled out from the upper open portion of the tubular frame body 40. At this time, the extension tube 200 is a constituent portion of the push button main body. Since the tubular inner wall 45 prevents the connection tool 30 and the push-down operation unit 20 from interfering with or being caught by the connection tool 30, the extension tube 200 is not only easy to take out, but also the connection tool 30 and the push-down operation unit 20 are pushed down. The operation unit 20 will not be damaged.

Similarly, before using the push button 100, as shown in FIG. 2, the printed paper piece 400 such as the instruction manual is stored in a folded state and sandwiched between the internal spaces S of the tubular frame 40. ing. Therefore, the user can take out the printing paper piece 400 and check the material, specifications, usage, and the like of the push button 100 if necessary. Further, as shown in FIG. 2, an elongated shape is provided across the cylinder wall 41 at a position above the connector 30 between the receiving portions 47, 47 provided at two locations of the cylinder wall 41 of the cylinder frame body 40. A cover body 300 having a shape is bridged over. As a result, the connector 30 is protected by the elongated cover 300, so that the connector 30 interferes with foreign matter and is damaged before use, or dust or dirt adheres to the connector 30 and the connector 30 is attached. The internal passage of the body is not blocked, and the extension tube 200 can be prevented from being accidentally detached from the tubular frame body 40 by the cover body 300. The situation in which a foreign object hits the connector 30 and damages it is also exhibited by the fact that the height of the tubular wall 41 of the tubular frame 40 is higher than the height of the connector 30 protruding from the mounting portion 10. Further, the height of the cylinder wall 41 is higher than the height of the connector 30 protruding from the mounting portion 10, and an elongated cover 300 is deployed across the cylinder wall 41 at a position above the connector 30. This configuration also prevents the push-down operation unit 20 of the push button 100 from being accidentally pushed down. Needless to say, these covering bodies 300 and the printing paper piece 400 need to be removed in advance when the extension tube 200 is taken out from the internal space S.

FIG. 5 is a schematic perspective view showing a usage state of the push button 100. The push button 100 mounted on the aerosol container 1 is operated according to, for example, the following procedure. In the first stage, as shown in FIG. 5, the connection port 202 of the extension tube 200 is inserted into the connector 30 of the push button 100 to connect, and the extension tube 200 is routed to position the spray nozzle 201 in a predetermined spray area. .. Next, by pushing down the push-down operation portion 20 of the push button 100 with a finger, the stem 2 is pushed through the mounting portion 10 to spray the chemicals and gas contained in the aerosol container 1 into the spray nozzle of the extension tube 200. Inject from 201. Since it is not necessary to remove the cap from the aerosol container 1 at the start of the injection, the operability or the handleability at the start of the injection is improved as compared with the conventional case.

When the injection is interrupted or stopped, the finger of the hand is released from the pressing operation unit 20 of the push button 100 to release the pressing force. Then, the injection is stopped even though the stem 2 returns to the original position, and at the same time, the mounting portion 10 also returns to the original position. When the extension tube 200 is to be reused, the extension tube 200 is removed from the connection port 202, then wound in a circular shape and stored in the above-mentioned internal space S (see FIG. 3). In this way, since it is not necessary to remove the push button 100 itself from the aerosol container 1, the situation that the push button 100 is lost and the extension tube 200 is not lost does not occur.

In this embodiment, the push button 100 includes an engagement mechanism 60 for locking the stem 2 at the push position. Therefore, the engaging mechanism 60 can be used to hold the pressing operation unit 20 in the pressing position without using human power, thereby injecting the contents of the aerosol container 1 as a one-time use-up. It is possible to make it. That is, when the contents of the aerosol container 1 are jetted as a one-time use, the push-down operation unit 20 is pushed down as shown by the arrow P in FIG. Engage with the protrusion 62. By doing so, even if the finger of the hand is separated from the pressing operation unit 20, the stem 2 is held as it is at the pressing position, so that the contents of the aerosol container 1 can be sprayed as a one-time use. Become.

The push-down operation portion 20 of the illustrated example is formed in the shape of a tongue piece and projects laterally from the mounting portion 10.

The cylindrical frame 40 is cylindrical and has a bottomed tubular wall 41. As shown in FIGS. 1 to 3, the bottom wall 42, which is the bottom portion of the tubular wall 41, has a small-diameter circular protrusion 43 in a plan view at the center portion of the protrusion 43. One location in the circumferential direction of the mounting portion 10 is integrally connected to one location in the circumferential direction by a plate piece-shaped hinge portion 44 shown in FIG. The plate-shaped push-down operation portion 20 described above projects laterally from the mounting portion 10 on the opposite side of the hinge portion 44.

As shown in FIGS. 1 to 3, the tubular frame body 40 is provided with a tubular inner wall 45 that is raised upward from the protrusion 43. The tubular inner wall 45 is located inside the cylindrical wall 41 of the tubular frame body 40 and surrounds the mounting portion 10. Further, receiving portions 47 and 47 are provided at two locations on the opposite sides in the circumferential direction with the tubular wall 41 of the tubular frame 40 spaced apart from each other. Two ends of the elongated cover 300 shown in FIG. 1 on one side and the other side can be separately fitted into these receiving portions 47, 47, and thus can be fitted in this way. When the two ends of the elongated cover 300, one side and the other side, are fitted into the receiving portions 47, 47, the covering portion 300 is received by these receiving portions 47, 47, and the covering body 300 is connected as described above. It is deployed in a posture of crossing the cylinder wall 41 in the radial direction at a position above the tool 30.

The push button 100 including the mounting portion 10 corresponding to the constituent portion of the push button main body, the push-down operation portion 20, the tubular frame body 40, the tubular inner wall 45, the hinge portion 44, and the like is made of an integrally molded synthetic resin. The mounting portion 10 is insert-molded together with the metal fitting 30. Therefore, for the reason of molding technology, the push button 100 is formed with an arcuate opening 51 located below the receiving portions 47, 47 on the bottom wall 42 (see FIG. 2), and the upper surface of the protruding portion 43 is formed. Also, an opening 52 located below the mounting portion 10 is formed (see FIGS. 2 and 3).

In the push button 100 described above, the connector 30 is flexible with the extension tube 200 shown in FIG. 1, specifically, a spray nozzle 201 at the end and a connection port 202 with the connector 30 at the start. The connection port 202 of the extension tube 200 having a length of 500 mm or more is removable. In this embodiment, the space between the tubular inner wall 45 and the tubular wall 41 of the tubular frame 40 is formed in the circumferential region inside the tubular wall 41 of the tubular frame 40. The extension tube 200 obtained by winding the space S (see FIG. 3) in a circular shape as shown in FIG. 1 can be used as a storage space. To explain this more specifically, the extension tube 200 in which the connection port 201 is separated from the connection tool 30 and wound in a circular shape is stored along the entire circumference of the inner peripheral surface of the cylinder wall 41. The possible space is formed by the internal space S of the tubular frame body 40 surrounded by the entire circumference of the inner peripheral surface of the tubular inner wall 41, and moreover, the tubular inner wall 45 and the tubular frame body 40 are tubular. The space between the wall 41 and the wall 41 is made available as the internal space S. Further, the internal space S (see FIG. 2) can also be used as a space in which the printing paper piece 400 shown in FIG. 1 can be stored. The printed paper piece 400 includes a printed instruction indicating the material, specifications, usage, etc. of the push button 100, and depending on the size of the printed paper piece 400, it can be folded into a size that can be stored in the internal space S. ..

Next, as shown in FIG. 3, the fitting portion 48 is integrally provided with the small-diameter projecting portion 43 provided on the tubular frame body 40. The fitting portion 48 is formed in a tubular shape, and has a ring-shaped protrusion 49 protruding inward at the lower end portion thereof. Further, the inner diameter of the lower end portion of the tubular wall 41 of the tubular frame body 40 is sized so that it can be fitted to the caulking portion 3 provided in the upper portion of the body of the aerosol container 1.

Further, in this embodiment, a part of the tubular wall 41 and the tubular inner wall 45 of the tubular frame 40 is cut off at a portion facing the push-down operation unit 20 described above, and the cut-off portion thereof is pushed down. It is formed as an insertion opening 53, 54 for a finger that pushes down the operation unit 20 (see FIGS. 1 and 2). Further, the push button 100 has an engagement mechanism 60 for locking the stem 2 of the aerosol container 1 at the push-in position. As shown in FIG. 1 or 4, the engaging mechanism 60 is provided on the side of the first protrusion 61 provided on the push-down operation unit 20 and the tubular frame body 40 so that the first protrusion 61 can be engaged and disengaged. The first protrusion 61 is configured to get over the second protrusion 62 and engage with the second protrusion 62 by pushing down the push-down operation unit 20 with a finger.

The push button 100 described above is attached to the aerosol container 1 as shown in FIG. Specifically, by pushing the fitting portion 48 of the tubular frame body 40 into the mounting cup 4 of the aerosol container 1, the ring-shaped protrusion 49 of the fitting portion 48 is engaged with the outer peripheral edge of the mounting cup 4. As a result, the push button 100 is attached to and fixed to the aerosol container 1. When the fitting portion 48 is engaged with the outer peripheral edge of the mounting cup 4, the stem 2 of the aerosol container 1 faces the stem insertion port 11 provided in the mounting portion 10 of the push button 100, and the internal passage of the stem 2 is reached. The internal passage of the connector 30 of the mounting portion 10 communicates with the inside passage. In this embodiment, as described above, the push button 100 is attached to and fixed to the aerosol container 1 by engaging the ring-shaped protrusion 49 of the fitting portion 48 with the outer peripheral edge of the mounting cup 4. The push button 100 is attached to the aerosol container 1 by providing a protrusion or the like on the inner wall of the lower end of the tubular wall 41 of the tubular frame 40 and engaging the caulking portion 3 provided on the upper part of the body of the aerosol container 1. It may be attached and fixed.

On the other hand, before using the push button 100 , the connection port 202 is separated from the connection tool 30 in the internal space S of the tubular frame body 40 in the push button 100, as shown by a virtual line in FIG. The extension tube 200 wound in a circular shape is housed in a state of being positioned along the entire circumference of the inner peripheral surface of the tubular wall 41 of the tubular frame body 40 . Then, when the extension tube 200 is taken out from the internal space S, the end portion of the extension tube 200 is pulled out from the upper open portion of the tubular frame body 40. At this time, the extension tube 200 is a constituent portion of the push button main body. Since the tubular inner wall 45 prevents the connection tool 30 and the push-down operation unit 20 from interfering with or being caught by the connection tool 30, the extension tube 200 is not only easy to take out, but also the connection tool 30 and the push-down operation unit 20 are pushed down. The operation unit 20 will not be damaged.

Similarly, before using the push button 100, as shown in FIG. 2, the printed paper piece 400 such as the instruction manual is stored in a folded state and sandwiched between the internal spaces S of the tubular frame 40. ing. Therefore, the user can take out the printing paper piece 400 and check the material, specifications, usage, and the like of the push button 100 if necessary. Further, as shown in FIG. 2, an elongated shape is provided across the cylinder wall 41 at a position above the connector 30 between the receiving portions 47, 47 provided at two locations of the cylinder wall 41 of the cylinder frame body 40. A cover body 300 having a shape is bridged over. As a result, the connector 30 is protected by the elongated cover 300, so that the connector 30 interferes with foreign matter and is damaged before use, or dust or dirt adheres to the connector 30 and the connector 30 is attached. The internal passage of the body is not blocked, and the extension tube 200 can be prevented from being accidentally detached from the tubular frame body 40 by the cover body 300. The situation in which a foreign object hits the connector 30 and damages it is also exhibited by the fact that the height of the tubular wall 41 of the tubular frame 40 is higher than the height of the connector 30 protruding from the mounting portion 10. Further, the height of the cylinder wall 41 is higher than the height of the connector 30 protruding from the mounting portion 10, and an elongated cover 300 is deployed across the cylinder wall 41 at a position above the connector 30. This configuration also prevents the push-down operation unit 20 of the push button 100 from being accidentally pushed down. Needless to say, these covering bodies 300 and the printing paper piece 400 need to be removed in advance when the extension tube 200 is taken out from the internal space S.

FIG. 5 is a schematic perspective view showing a usage state of the push button 100. The push button 100 mounted on the aerosol container 1 is operated according to, for example, the following procedure. In the first stage, as shown in FIG. 5, the connection port 202 of the extension tube 200 is inserted into the connector 30 of the push button 100 to connect, and the extension tube 200 is routed to position the spray nozzle 201 in a predetermined spray area. .. Next, by pushing down the push-down operation portion 20 of the push button 100 with a finger, the stem 2 is pushed through the mounting portion 10 to spray the chemicals and gas contained in the aerosol container 1 into the spray nozzle of the extension tube 200. Inject from 201. Since it is not necessary to remove the cap from the aerosol container 1 at the start of the injection, the operability or the handleability at the start of the injection is improved as compared with the conventional case.

When the injection is interrupted or stopped, the finger of the hand is released from the pressing operation unit 20 of the push button 100 to release the pressing force. Then, the injection is stopped even though the stem 2 returns to the original position, and at the same time, the mounting portion 10 also returns to the original position. When the extension tube 200 is reused, the connection port 202 of the extension tube 200 is removed from the connector 30 and then wound into a circular shape and stored in the above-mentioned internal space S (see FIG. 3). I will do it. In this way, since it is not necessary to remove the push button 100 itself from the aerosol container 1, the situation that the push button 100 is lost and the extension tube 200 is not lost does not occur.

In this embodiment, the push button 100 includes an engagement mechanism 60 for locking the stem 2 at the push position. Therefore, the engaging mechanism 60 can be used to hold the pressing operation unit 20 in the pressing position without using human power, thereby injecting the contents of the aerosol container 1 as a one-time use-up. It is possible to make it. That is, when the contents of the aerosol container 1 are jetted as a one-time use, the push-down operation unit 20 is pushed down as shown by the arrow P in FIG. Engage with the protrusion 62. By doing so, even if the finger of the hand is separated from the pressing operation unit 20, the stem 2 is held as it is at the pressing position, so that the contents of the aerosol container 1 can be sprayed as a one-time use. Become.

In this embodiment, although the example in which the tubular inner wall 45 is provided on the tubular frame body 40 and is located inside the tubular wall 41 of the tubular frame body 40 and surrounds the mounting portion 10 has been described, the cylinder It is also possible to omit the shape inner wall 45.

Regarding the push button for the aerosol container, which not only makes it possible to improve, but also makes it possible to store the extension tube before use out of the way.

Many conventional aerosol containers are provided with a stem that projects upward at the top of a cylindrical container that stores spray components such as drugs and gas as contents, and this stem is equipped with a push button equipped with a spray nozzle. Is installed. In this type of aerosol container, when the stem is pushed in through the operation of pushing down the push button with the finger of the hand, the valve linked to the stem opens and the contents are ejected from the spray nozzle of the push button and injection is started, and the injection is started from the push button. When the hand is released, the stem returns from the pushed position to the initial position, the valve closes, the contents are not ejected from the spray nozzle, and the injection is stopped. In an aerosol container having this configuration, a cap that covers the push button and spray nozzle attached to the stem is generally attached to and detached from the container, and when in use, the cap is removed from the container. After that, the push button is operated.

On the other hand, when spraying the contents of an aerosol-type injection device such as a drug into a certain area in an automobile, a resin tube is used to guide the contents to the spray area (for example, Patent Document 1). reference). In addition, in an aerosol container in which a cap that covers the push button and spray nozzle as described above is attached to and detached from the container, accessories such as nozzles and brushes, instruction manuals, etc. are stored in the storage section provided on the cap. This is also done (see, for example, Patent Document 2). Further, the instruction manual is also stored in the annular groove-shaped storage chamber provided in the cap (see, for example, Patent Document 3).

As shown in FIG. 1 or 4, the engaging mechanism 60 is provided on the side of the first protrusion 61 provided on the push-down operation unit 20 and the tubular frame body 40 so that the first protrusion 61 can be engaged and disengaged. The first protrusion 61 is configured to get over the second protrusion 62 and engage with the second protrusion 62 by pushing down the push-down operation unit 20 with a finger.

The push button 100 described above is attached to the aerosol container 1 as shown in FIG. Specifically, by pushing the fitting portion 48 of the tubular frame body 40 into the mounting cup 4 of the aerosol container 1, the ring-shaped protrusion 49 of the fitting portion 48 is engaged with the outer peripheral edge of the mounting cup 4. As a result, the push button 100 is attached to and fixed to the aerosol container 1. When the fitting portion 48 is engaged with the outer peripheral edge of the mounting cup 4, the stem 2 of the aerosol container 1 faces the stem insertion port 11 provided in the mounting portion 10 of the push button 100, and the internal passage of the stem 2 is reached. The internal passage of the connector 30 of the mounting portion 10 communicates with the inside passage. In this embodiment, as described above, the push button 100 is attached to and fixed to the aerosol container 1 by engaging the ring-shaped protrusion 49 of the fitting portion 48 with the outer peripheral edge of the mounting cup 4. The push button 100 is attached to the aerosol container 1 by providing a protrusion or the like on the inner wall of the lower end of the tubular wall 41 of the tubular frame 40 and engaging the caulking portion 3 provided on the upper part of the body of the aerosol container 1. It may be attached and fixed.

On the other hand, before using the push button 100, the connection port 202 is separated from the connection tool 30 in the internal space S of the tubular frame body 40 in the push button 100, as shown by a virtual line in FIG. The extension tube 200 wound in a circular shape is housed in a state of being positioned along the entire circumference of the inner peripheral surface of the tubular wall 41 of the tubular frame body 40. Then, when the extension tube 200 is taken out from the internal space S, the end portion of the extension tube 200 is pulled out from the upper open portion of the tubular frame body 40. At this time, the extension tube 200 is a constituent portion of the push button main body. Since the tubular inner wall 45 prevents the connection tool 30 and the push-down operation unit 20 from interfering with or being caught by the connection tool 30, the extension tube 200 is not only easy to take out, but also the connection tool 30 and the push-down operation unit 20 are pushed down. The operation unit 20 will not be damaged.

Similarly, before using the push button 100, as shown in FIG. 2, the printed paper piece 400 such as the instruction manual is stored in a folded state and sandwiched between the internal spaces S of the tubular frame 40. ing. Therefore, the user can take out the printing paper piece 400 and check the material, specifications, usage, and the like of the push button 100 if necessary. Further, as shown in FIG. 2, an elongated shape is provided across the cylinder wall 41 at a position above the connector 30 between the receiving portions 47, 47 provided at two locations of the cylinder wall 41 of the cylinder frame body 40. A cover body 300 having a shape is bridged over. As a result, the connector 30 is protected by the elongated cover 300, so that the connector 30 interferes with foreign matter and is damaged before use, or dust or dirt adheres to the connector 30 and the connector 30 is attached. The internal passage of the body is not blocked, and the extension tube 200 can be prevented from being accidentally detached from the tubular frame body 40 by the cover body 300. The situation in which a foreign object hits the connector 30 and damages it is also exhibited by the fact that the height of the tubular wall 41 of the tubular frame 40 is higher than the height of the connector 30 protruding from the mounting portion 10. Further, the height of the cylinder wall 41 is higher than the height of the connector 30 protruding from the mounting portion 10, and an elongated cover 300 is deployed across the cylinder wall 41 at a position above the connector 30. This configuration also prevents the push-down operation unit 20 of the push button 100 from being accidentally pushed down. Needless to say, these covering bodies 300 and the printing paper piece 400 need to be removed in advance when the extension tube 200 is taken out from the internal space S.

FIG. 5 is a schematic perspective view showing a usage state of the push button 100. The push button 100 mounted on the aerosol container 1 is operated according to, for example, the following procedure. In the first stage, as shown in FIG. 5, the connection port 202 of the extension tube 200 is inserted into the connector 30 of the push button 100 to connect, and the extension tube 200 is routed to position the spray nozzle 201 in a predetermined spray area. .. Next, by pushing down the push-down operation portion 20 of the push button 100 with a finger, the stem 2 is pushed through the mounting portion 10 to spray the chemicals and gas contained in the aerosol container 1 into the spray nozzle of the extension tube 200. Inject from 201. Since it is not necessary to remove the cap from the aerosol container 1 at the start of the injection, the operability or the handleability at the start of the injection is improved as compared with the conventional case.

When the injection is interrupted or stopped, the finger of the hand is released from the pressing operation unit 20 of the push button 100 to release the pressing force. Then, the injection is stopped even though the stem 2 returns to the original position, and at the same time, the mounting portion 10 also returns to the original position. When the extension tube 200 is reused, the connection port 202 of the extension tube 200 is removed from the connector 30 and then wound into a circular shape and stored in the above-mentioned internal space S (see FIG. 3). I will do it. In this way, since it is not necessary to remove the push button 100 itself from the aerosol container 1, the situation that the push button 100 is lost and the extension tube 200 is not lost does not occur.

In this embodiment, the push button 100 includes an engagement mechanism 60 for locking the stem 2 at the push position. Therefore, the engaging mechanism 60 can be used to hold the pressing operation unit 20 in the pressing position without using human power, thereby injecting the contents of the aerosol container 1 as a one-time use-up. It is possible to make it. That is, when the contents of the aerosol container 1 are jetted as a one-time use, the push-down operation unit 20 is pushed down as shown by the arrow P in FIG. Engage with the protrusion 62. By doing so, even if the finger of the hand is separated from the pressing operation unit 20, the stem 2 is held as it is at the pressing position, so that the contents of the aerosol container 1 can be sprayed as a one-time use. Become.
