Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an injection button fitted to a discharge pipe such as a valve stem of an aerosol container or a suction piston of a pump. Long nozzle is connected,
When the long nozzle is bent by the elastic pipe part and is detachably locked to the container side by the pipe locking piece in the retracted state along the container and released from the pipe locking tool, the elastic return force of the elastic pipe part The present invention relates to an ejection button with a long nozzle that protrudes forward.

[0002]

2. Description of the Related Art As an injection button with a long nozzle of this kind, according to Japanese Utility Model Publication No. 58-21555, a coil spring capable of returning to a flexible pipe portion at the base end portion of the long nozzle is provided. It is well known that the pipe locking device of the cover cap is locked along the container in a retracted state, and when it is released, the elastic locking force of the coil spring automatically sets it to a use position in which it faces forward.

[0003]

As a result, an insecticide or the like can be sprayed to a target position at a front position separated by a simple operation without being sprayed in the middle region, but the length of the long nozzle is long. The premise is that the height width of is not exceeded.

In view of the above points, an object of the present invention is to provide an injection button with a long nozzle which can be easily set at a position further apart in front by utilizing an elastic return force.

[0005]

In order to achieve this object, the present invention provides, according to claim 1, a flow passage formed inside a discharge pipe projecting from a container head at a base end thereof. By connecting the elastic pipe portion at the base end portion of the long nozzle to the flow path outlet formed on the peripheral surface portion of the injection button, the long nozzle is bent by the elastic pipe portion and extends along the container. In the stored state, it is detachably locked to the pipe locking piece on the container side, and when released from the pipe locking device, it projects forward due to the elastic restoring force of the pipe part, and the contents are pressed by pressing the injection button. At least one of the long nozzles is used in the injection button with the long nozzle adapted to discharge
An elastic pipe part having an elastic return force is also interposed in the middle position of the part, and the middle position is set so that the elastic pipe part folded back in the stored state does not exceed the bottom surface of the container. It is characterized in that it is provided with a pipe locking piece for removably locking the long nozzle portion to the container side.

In the retracted state, the long nozzle is bent by the elastic pipe portion at the base end and locked by the pipe locking piece, and the elastic pipe portion interposed at an intermediate position does not exceed the bottom surface of the container. It is folded back and the other end is locked to the pipe locking piece. When it is disengaged from the pipe locking piece during use, it is automatically set forward by the elastic restoring force of the elastic pipe portion.

BEST MODE FOR CARRYING OUT THE INVENTION An injection button with a long nozzle according to an example of an embodiment of the present invention will be described with reference to FIGS. This injection button is constructed by surrounding a button 9 mounted on the discharge pipe of the aerosol container 1 with a long nozzle 20 protruding from the button cap 10 with a cover cap 10 mounted on the head of the aerosol container 1. ing.

The cover cap 10 is formed with a recess 15 having a cylindrical central opening 16 between the peripheral wall portions 19 on both sides thereof, and the outer peripheral surface 11 has a curl of the shoulder portion of the aerosol container 1 and the eyeglass lid. Surrounding the part 2, the intermediate peripheral surface 12 is engaged with the curl part 3 of the mounting cup by an annular projection 12a at the lower end. The button 9 is inserted into the inner peripheral surface 13 forming the central opening 16 so that the longitudinal flow path 6 is fitted to the stem 4 and the notch 14 formed in the inner peripheral surface 13. The protruding piece 5 of the button 9 is inserted to prevent the button 9 from coming off.

A lateral flow path 7 communicates with the tip of the vertical flow path 6, and the flow path outlet has an engagement groove 7a whose inner diameter changes stepwise on the peripheral surface of the front surface of the button 9. Form,
The base end portion is fitted to the long nozzle 20.

The elongated nozzle 20 is connected to a flexible pipe 22 having a plug pipe 21 of a corresponding shape which engages with the engagement groove 7a at its base end, and a non-flexible pipe connected via a connector 26. Pipe 23, a flexible pipe 24 connected to this pipe via a connector 26, and a tip 27 fitted to this pipe via a connector 26 and having an injection port at its tip. A bendable pipe 25, so that the pipes 22, 24 form an elastic pipe section.
A coil spring 28 is attached to the outer circumference of the.

The outer peripheral surface 11 of the front portion of the cover cap 10
At the lower end portion of the pipe 22, a pipe locking piece 17 is formed in an arc shape having an inner diameter corresponding to the outer diameter of the pipe 22 so as to be engaged with the connector 26 of the pipe 22 and slightly larger than a semicircle. On the outer peripheral surface 11 adjacent to this locking piece,
A similar arcuate pipe locking piece 18 for engaging the pipe 25 near the base of the tip 27 is provided in a protruding manner.

The lengths of the non-bendable pipes 23 and 25 are set according to the height and width of the aerosol container 1, and the pipe 2
By folding back 4, the long nozzle 20 is attached to the pipe locking piece 17,
18 in a state of being locked and stored, the pipe 2 in the middle position
4 is in a folded state so as not to exceed the bottom surface of the aerosol container 1.

The operation of the jet button with the long nozzle thus configured is as follows. In the storage state of the long nozzle 20 shown in FIG. 2, the base end portions of the long nozzle 20 are elastic pipe portions 22 and 2.
The connector 26 is bent at 8 and the connector 26 is
7, the elastic pipe portions 24 and 28 are folded back at a position slightly above the bottom surface of the aerosol container 1, and the tip end of the pipe 25 at the end is folded into the pipe locking piece 1.
It is locked to 8.

In use, when the long nozzle 20 is detached from the pipe locking pieces 17 and 18, the elastic pipe portions 22 and 2 are released.
8; 24, 28 are linearly returned by the elastic return force reinforced by the coil spring 28, so that the long nozzle 20 moves forward in a direction substantially orthogonal to the aerosol container 1 as shown in FIG. It is set automatically. As a result, it becomes possible to spray directly to the front position at a distance that is sufficiently longer than the height width of the container, and it becomes easy to kill insects on the back side of the refrigerator.

As another embodiment, the pipe locking piece is not limited to the cover cap, but may be an annular shoulder cover that covers the shoulder portion of the container with the button protruding or the peripheral surface itself of the aerosol container. It is possible to project it. In addition, the elastic pipe portion does not use a coil spring, and in some cases, the elasticity of the material of the pipe is used as it is,
Other configurations such as bellows are possible. Further, it may be possible to provide three or more elastic pipe portions and pipe locking pieces interposed in the middle position and to fold the elastic pipe portions and the pipe locking pieces in two or more stages.

Further, the injection button of the present invention can be configured to be attached to a discharge pipe such as a suction piston of a container with a pump, instead of the valve stem of the aerosol container.

[0017]

EFFECTS OF THE INVENTION According to the present invention, the long nozzle can be set to be sufficiently long, particularly, the height width of the container or more by being able to be bent so that it can be automatically returned even in the middle position.
