Description

[Detailed description of the invention] Industrial application field This invention sprays aerosol contents such as insecticides into areas that are difficult to spray with a normal spray nozzle, such as between furniture or narrow walls. The present invention relates to a long nozzle for an aerosol container, which is used when spraying an aerosol agent for local spraying, such as a lubricant, to a limited target area.

BACKGROUND ART Conventionally, long nozzles for aerosol containers have existed that spray aerosol contents into areas where it is difficult to spray with a normal spray nozzle, such as between furniture or narrow parts of a wall surface. However, since the nozzle is long, it protrudes from the side of the aerosol container and gets in the way when it is stored or transported, and if it is removed from the aerosol container, it may take a lot of effort to attach or be lost. It had the disadvantage of

In addition, in order to eliminate these drawbacks, there are also devices in which the elongated nozzle can be bent so that it becomes parallel to the side surface of the aerosol container. In this case as well, Utility Model Application No. 57-28758, Utility Model Application No. 57-123661, Utility Model Application No. 53-146118, Utility Model Application No. 53-146119,
As in the invention described in Japanese Patent No. 58-8367, since the long nozzle is rotatably bent, the connecting portion between the long nozzle side and the main body side of the aerosol container is formed into a spherical curved surface. Therefore, a high degree of machining precision is required to achieve good sealing performance, but the nozzle mechanism of extremely small aerosol devices has poor machining precision, and due to poor contact between the spherical curved surfaces, etc. It had the disadvantage of leakage.

Furthermore, in the conventional example described above, the communication connection between the long nozzle side and the main body side of the aerosol container is only possible when the long nozzle is positioned at a certain angle, such as when the nozzle is positioned at right angles to the aerosol container. It becomes possible. However, in order to spray the aerosol contents in areas that are difficult to spray with a normal spray nozzle, such as between furniture or narrow parts of the wall, the connection angle between the aerosol container and the long nozzle must be specified. In order to spray the aerosol contents, the user is often forced to do so in an unnatural position. Furthermore, the aerosol container is often injected at an angle, and the propellant or propellant gas comes into contact with the outlet of the contents inside the aerosol container, and only these propellants or propellant gases are injected. However, it is likely to be misused, making it impossible to spray the contents.

Problems that the invention attempts to solve This invention attempts to solve the problems mentioned above, and is intended to spray in areas where it is difficult to spray with a normal spray nozzle, such as between furniture or narrow parts of walls. , capable of spraying the aerosol contents;
When storing or transporting a long nozzle for an aerosol container, it should be placed parallel to the side of the aerosol container without being removed, and it may protrude from the side of the aerosol container and get in the way, or it may be difficult to install. Of course, it is important to ensure that there is no damage or loss, and there is no need for a high level of precision.
The purpose is to ensure good sealing performance during injection and to reliably prevent liquid leakage.

Another purpose is to make it possible to spray the aerosol contents at a position where the connection angle between the aerosol container and the long nozzle is not specified, and to spray unnaturally in areas where it is difficult to spray with a normal spray nozzle. The purpose is to make it possible to easily spray the contents of the aerosol without having to take a difficult posture.

Another purpose is to prevent misuse caused by spraying an aerosol container at an angle, and to make it possible to easily change only the direction and angle of the aerosol contents while keeping the aerosol container in an upright position. That is.

Means for solving the problems In order to solve the problems mentioned above, the present invention
A rotating shaft of a support body to which a long nozzle is fixed is rotatably fixed to a fixed body protruding from one side of the cap of the aerosol container, and a fixed body is formed at the axis of this rotating shaft. One end of the communication path that constantly communicates with the stem via the lead-out path is opened, and the other end of this communication path is communicated with a long nozzle fixed to the support body, and a seal portion provided on the outer periphery of the rotating shaft is connected. , in planar contact with the fixed body.

In addition, the communication passage and the stem are connected via an outlet passage, and a stopper located facing a part of this outlet passage is pressed by a pressing protrusion protruding from a part of the outer surface of the support body, so that the elongated nozzle It is also possible to close the outlet path by pressing when the aerosol container is positioned parallel to the aerosol container.

Function In the device configured as described above, in order to spray the aerosol contents, the long nozzle located parallel to the aerosol container is raised upward at an arbitrary angle, and the push button is pressed to release the aerosol. When the valve mechanism of the container is opened, the aerosol contents are injected from the stem through the communication path and from the elongated nozzle. Since the communication passage has one end opened at the axis of the rotation shaft, the rotation of the support at any angle when the long nozzle is raised will cause the long nozzle to The connection state with the stem can be maintained at all times. Therefore, it is possible to spray the aerosol contents at a position where the connection angle between the aerosol container and the long nozzle is not specified, and it takes an unnatural posture even in areas where it is difficult to spray with a normal spray nozzle. To easily spray aerosol contents without any trouble.

In addition, no matter what the connection angle between the long nozzle and the aerosol container, spraying is always possible, so the direction and angle of spraying the aerosol contents can be freely determined while keeping the aerosol container upright. It is possible to inject only the propellant and propellant gas, and there is no possibility of misuse that would make it impossible to inject the contents.

In addition, the seal part provided on the outer circumference of the rotating shaft,
Since it is in planar contact with the fixed body, there is no airtightness that occurs when arcuate surfaces come into contact with each other, and the sealing performance during injection is good and liquid leakage is reliably prevented. can. Further, after the spraying operation is completed, the elongated nozzle can be positioned parallel to the aerosol container by rotating from the rotation axis.

Embodiment An embodiment of the present invention will be described below. Reference numeral 1 denotes an aerosol container, and a cap 4 is fixed to the upper end of a body 2 via a seaming portion 3, and a mounting cup 5 is attached to the cap 4. A stem 6 protrudes from the center of the mounting cup 5, which is fixed and connected to an internal valve mechanism. Press button 7 on this stem 6
is fixed, and the push button 7 is connected and fixed to the fixed main body 11 via the outlet path 9 of the bendable outlet tube 8.

This fixed body 11 partially protrudes from one side of the cap 12 of the aerosol container 1, and this protruding portion 13
A rotating shaft 16 of a support body 15 to which a long nozzle 14 is fixed is rotatably supported and fixed. One end of a communication path 17 that communicates with the stem 6 via the lead-out path 9 is opened at the axis of the rotation shaft 16, and the other end of the communication path 17 is bent by 90 degrees to form a support body 15. It communicates with a long nozzle 14 fixed to.

Further, the lead-out passage 9 that communicates the communication passage 17 with the stem 6 is connected to the stem 6 at one end, collides with the collision wall 18 of the fixed body 11 at right angles, and then is bent into an L-shape. It is connected to 17. Further, a seal portion 20 is formed by an O-ring on the outer circumferential position of the rotation shaft 16 that forms the communication path 17, and this seal portion 20 and the inner surface of the retaining wall 21 of the fixed body 11 are in planar contact with each other. There is.

In the configuration as described above, in order to spray the aerosol contents, the aerosol container 1
The long nozzle 14 located parallel to the support body 1
5 to an arbitrary angle upward, and press push button 7. By pressing the push button 15, the valve mechanism of the aerosol container 1 is opened, and the aerosol contents are injected from the long nozzle 14 from the stem 6 through the outlet path 9 and the communication path 17.

Further, since the communication passage 17 is in continuous communication with the stem 6 via the outlet passage 9 and has one end opened at the axis of the rotation shaft 16, the long nozzle 1
No matter what angle the support body 15 rotates as the support member 4 is raised, the elongated nozzle 14 can always remain connected to the stem 6. Therefore, it is possible to spray the aerosol contents at a position where the connection angle between the aerosol container 1 and the long nozzle 14 is not specified, and it is possible to spray the aerosol contents even in areas where it is difficult to spray with a normal spray nozzle. To make it possible to easily dispense the contents of an aerosol without removing the contents.

In addition, no matter what the connection angle between the elongated nozzle 14 and the aerosol container 1, injection is always possible, so the direction and angle of the injection of the aerosol contents can be freely determined while the aerosol container 1 is kept upright. It is possible to inject only the propellant and propellant gas, and there is no possibility of misuse that would make it impossible to inject the contents.

In addition, since the seal portion 20 provided on the outer periphery of the rotating shaft 16 is in planar contact with the inner surface of the retaining wall 21 of the fixed body 11, a high degree of machining accuracy is achieved as in the case of mutual contact between spherical curved surfaces. without being asked,
It is possible to maintain airtightness, improve sealing performance during injection, and reliably prevent liquid leakage. In addition, after the spraying operation is completed, by rotating from the rotation shaft 16 and positioning the long nozzle 14 parallel to the aerosol container 1, the nozzle 14 does not protrude from the side of the aerosol container 1 and become a hindrance. Furthermore, since the elongated nozzle 14 does not need to be removed, there is no risk of it being lost.

In the above embodiment, the connection between the stem 6 and the communication path 17 via the lead-out path 9 is always connected, so that if the push button 7 is pressed by mistake during storage or transportation, etc. , the possibility of ejection of the aerosol contents arises. In order to prevent this danger, in other different embodiments, as shown in FIGS. 4 and 5, a thin, bendable collision wall 18 is used.
Then, the stopper 22 is protruded, and the stopper 22 is positioned so as to face a part of the outlet passage 9 connecting the communication passage 17 and the stem 6. Then, the stem 6 and the communicating path 17 are connected to each other through the outlet passage 9 through the stopper 22 , and the stopper 22 is pressed tightly against the outlet passage 9 on a part of the outer surface of the support body 15 via the collision wall 18 . , the pressing protrusion 23 protrudes.

This pressing protrusion 23 presses the stopper 22 with the long nozzle 14 positioned parallel to the aerosol container 1.
is pressed against the lead-out path 9 to close the lead-out path 9 and protrude to a position where communication between the stem 6 and the communication path 17 is cut off. Further, when the elongated nozzle 14 moves in the aerosol content spouting direction, the protruding length of the pressing protrusion 23 is adjusted so as not to press the collision wall 18. Further, when the aerosol contents are injected, the outlet passage 9 is released by this pressure release and the jetting pressure of the aerosol contents.

Effects of the invention Since the present invention is configured as described above, the long nozzle and the stem are always connected even when the support body is rotated at any angle as the long nozzle is raised. can be maintained. Therefore, it is possible to spray the aerosol contents at a position where the connection angle between the aerosol container and the long nozzle is not specified, and it takes an unnatural posture even in areas where it is difficult to spray with a normal spray nozzle. To easily spray aerosol contents without any trouble.

In addition, no matter what the connection angle between the long nozzle and the aerosol container, spraying is possible at all times, so the direction of spraying the aerosol contents can be freely determined while keeping the aerosol container upright. Only the propellant and propellant gas are injected, and there is no possibility of misuse that would make it impossible to inject the contents.

In addition, the seal part provided on the outer circumference of the rotating shaft,
Since it is in plane contact with the fixed body, it is possible to maintain airtightness without requiring a high level of machining precision in extremely small nozzle mechanisms, as in the case of mutual contact between spherical curved surfaces, and prevents airtightness. This does not occur, and the sealing performance when injecting the aerosol contents is good, and the occurrence of liquid leakage can be reliably prevented. Also, after the spraying work is completed, it rotates from the rotation axis,
By positioning the nozzle body parallel to the aerosol container, it will not protrude to the side of the aerosol container and become an obstruction, and since the nozzle body does not need to be removed, there is no risk of losing it. It is something.
