[Technical field to which the invention belongs]

 The present invention relates to a spray used for spraying a liquid agent such as a lubricating oil, an insecticide and a hairdressing agent.

[0002]

[Problems to be solved by conventional technology and device]

 As a conventional spray of this type, there is one in which a jet nozzle is attached so that it can be freely replaced between the side of the head and the top of the head of the container that contains the liquid to be sprayed. If you want to insert the injection nozzle sideways on the upper surface, insert it on the side of the head and use it. As a result, even when it is desired to inject upward, the container does not fall sideways, and thus it is possible to avoid inability to inject. However, in such a configuration, it is necessary to change the direction of the injection nozzle every time the direction of the injection nozzle is changed, and thus there is a problem that the usability is poor.

Therefore, as an alternative spray, a spray has been developed in which the base end side of the spray nozzle is pivotally supported on the container so that the spray nozzle can swing up and down. However, even with the spray having such a configuration, when the liquid agent is to be sprayed laterally in the narrow gap, the spray nozzle cannot be directed to the lateral side in the gap unless the container is in a horizontal position. There was a problem that it was impossible to inject with the posture.

[0004]

[Problems to be solved by the device]

An object of the present invention is to solve such problems and to provide a spray in which the direction of the injection nozzle can be easily changed up, down, left, and right while the container containing the injection liquid agent is in an upright posture. To do.

[0006]

[Means for Solving the Problems]

 The spray according to the first aspect of the present invention is a spray having a straw-shaped injection nozzle, wherein the injection nozzle is a joint tube having a ball joint on the mounting base end side, and the spray nozzle is vertically and horizontally centered on the ball joint. It can swing freely. With this configuration, the orientation of the spray nozzle can be easily changed not only up and down but also left and right while the container containing the spray liquid is standing upright, so the spray nozzle can be installed laterally in a narrow gap. Can be plugged and jetted. According to a second aspect of the present invention, in the structure of the first aspect of the invention, the injection nozzle is a ball joint having a through hole passing through a center thereof, and a thin tubular member inserted into and connected to the through hole of the ball joint. And a nozzle body of the same. In the case of this configuration, the injection nozzle having the ball joint can be easily manufactured only by inserting the nozzle body into the through hole of the ball joint, so that the cost can be reduced. According to a third aspect of the present invention, in the configuration of the second aspect of the invention, a reinforcing pipe for externally fitting the nozzle body to the nozzle body insertion side opening of the ball joint to reinforce the mounting base end side of the nozzle body. It is a projecting part. With this configuration, the base end side of the nozzle body that is connected to the ball joint is reinforced by the reinforcing pipe section, so even if the nozzle diameter of the nozzle body is small, as the direction of the injection nozzle is repeatedly changed, It can prevent the main body from bending or breaking at the base end. Further, since the insertion margin of the nozzle body with respect to the ball joint becomes long, it is possible to reliably prevent the nozzle body from coming off from the ball joint. According to a fourth aspect of the present invention, in the configuration according to any one of the first to third aspects, an operation knob for changing the direction of the injection nozzle is attached to the injection nozzle so as to be slidable in the axial direction of the injection nozzle. It is a thing. In the case of this configuration, since it is possible to change the direction of the injection nozzle by grasping the operation knob, it is possible to prevent the operation nozzle from bending due to the operation force being concentrated on a part of the injection nozzle. Further, since the operation knob can be slid, the knob portion of the injection nozzle can be freely changed so as not to apply an unreasonable force to the injection nozzle.

An operation button 9 for injection operation is provided at the center of the upper portion of the cap 5. The operation button 9 is made of a molded product such as resin, and a lower portion thereof is provided with a vertical pipe portion 11 connected to a vertically movable conducting pipe 10 penetrating the center of the top of the container body 4 and the vertical pipe portion 11. And a lateral pipe portion 12 that communicates with the outer pipe and extends in the outer diameter direction are integrally formed. The conduit tube 10 is connected to a pump device (not shown) arranged in the upper portion of the container body 4, and the conduit tube 10 is pushed down by the operation button 9 to pump up the liquid agent of the pump device. The action is taken. Further, a lead-out path 13 which is connected to the lateral pipe portion 12 of the operation button 9 and opens at the outer peripheral surface of the cap is formed on the outer periphery of the upper portion of the cap 5. The connecting portion of the lateral tube portion 12 of the operation button 9 with the outlet path 13 is a thin portion 12a, so that the operation button 9 can be vertically swung.

The injection nozzle 3 is connected to the opening 13 a of the outlet path 13 on the outer periphery of the upper portion of the cap 5. The injection nozzle 3 is composed of a thin tube-shaped nozzle body 14 and a ball joint 15 having a through hole 15a passing through the center thereof, and the base end of the nozzle body 14 is inserted into the through hole 15a of the ball joint 15 so as to be mutually connected. Connected to. With such a configuration, the injection nozzle 3 having the ball joint 15 can be easily and inexpensively assembled. As shown in an enlarged view in FIG. 2, a spherical seat 16 that rotatably supports the ball joint 15 of the injection nozzle 3 is formed in the opening 13a of the lead-out passage 13 on the upper outer periphery of the cap 5, and Thus, the injection nozzle 3 is supported on the cap 5 so as to be swingable vertically and horizontally about the ball joint 15. Further, an O-ring 17 is interposed between the ball joint 15 and the enlarged diameter stepped portion 13a1 of the opening 13a of the outlet passage 13 to seal the connecting portion between the injection nozzle 3 and the outlet passage 13. Has been.

An operation knob 19 for changing the direction of the injection nozzle 3 is attached to the nozzle body 14 of the injection nozzle 3. By grasping the operation knob 19 and changing the direction of the injection nozzle 3, it is possible to avoid that the external force due to the operation is concentrated and applied to a part of the nozzle body 14, and the injection nozzle 3 is bent or bent by the external force. Can be prevented. The operation knob 19 has a sleeve 19a into which the nozzle body 14 is inserted at the base end thereof, and is thereby slidable in the axial direction of the nozzle body 14. By making the injection nozzle 3 slidable in this way, when the direction of the injection nozzle 3 is changed, the picked portion of the injection nozzle 3 can be freely changed so that an unreasonable force is not applied to the injection nozzle 3. Further, the operation knob 19 can also be laid down in its thickness direction.

In the case of this spray 1, since the ball joint 15 of the injection nozzle 3 is rotatably supported by the spherical seat 16 of the opening 13a of the lead-out path 13 on the upper outer periphery of the cap 5, the posture in which the container 2 is erected is shown. As it is, the direction of the injection nozzle 3 can be easily rocked not only vertically but also horizontally as shown in FIGS. 4 to 6, and the liquid agent can be sprayed vertically and horizontally in the gap. The liquid agent contained in the container body 4 is pushed by the operation button 9 to push down the conduit tube 10, and the pump device disposed in the upper part of the container body 4 causes the liquid agent to be released from the operation tube 9 through the conduit tube 10. It is led out to the vertical pipe portion 11, the horizontal pipe portion 12, and the outlet passage 13 and is jetted from the jet nozzle 3.

In the above embodiment, the through hole 15a of the ball joint 15 has substantially the same diameter over its entire length, but the opening side of the through hole 15a facing the lead-out path 13 may be opened widely. In this case, even if the swing angle of the injection nozzle 3 is further increased, the injection nozzle 3 and the outlet passage 13 can communicate with each other, and the injection can be performed.

Further, in the above-described embodiment, the ball joint 15 of the injection nozzle 3 is a substantially perfect sphere, but if the swinging angle range of the injection nozzle 3 may be limited to some extent, the nozzle main body of the ball joint 15 may be used. A part of the protruding side 14 and a part of the side facing the outlet path 13 may be aspherical.
