Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a jet button body in which a vertical central flow passage portion fitted at a base end to a discharge pipe protruding from a container head is stored in a container side when not in use, and is stored in a container side when in use. The present invention relates to an ejection button with a long nozzle for an aerosol container or a container with a pump provided with a long nozzle set at a position protruding forward from a peripheral surface.
[0002]
[Prior art]
As this type of ejection button with a long nozzle, the base end of the long nozzle is connected to the ejection button via a rotary coupling, and the rotary coupling is moved from a storage position along a container peripheral surface to a use position in front. In this case, according to Japanese Utility Model Laid-Open Publication No. Hei 5-7366, the injection mode is set to a rotary valve so that the fuel is injected forward as usual without passing through the long nozzle at the storage position where the long nozzle is not used. It is also well-known to switch over.
[0003]
However, in the case of such a long nozzle, it is necessary to provide a structure of a rotating part in which liquid leakage is considered. Therefore, according to Japanese Utility Model Publication No. 58-21555, a returnable coil spring is provided on a flexible pipe portion at the base end portion of a long nozzle, and the coil spring is stored in a pipe locking device of a cover cap along the container. It is well known that when the coil spring is disengaged, the coil spring is automatically set to the use position facing forward by the elastic return force of the coil spring.
[0004]
[Problems to be solved by the invention]
However, in this case, if it is intended to accurately set the nozzle at the use position, there arises a problem that the structure of the long nozzle itself having elasticity or the structure of restraining against elasticity at both the storage and use positions becomes complicated. .
[0005]
In view of the above, an object of the present invention is to provide an ejection button with a long nozzle which can be set to a use position by a slide operation.
[0006]
[Means for Solving the Problems]
In order to achieve this object, according to the present invention, the present invention provides a jet button body in which a vertical central flow passage portion fitted at a base end to a discharge pipe protruding from a container head is formed. A long nozzle which is stored in the container when not in use and is set at a use position protruding forward from the peripheral surface of the container when in use is attached, so that the content is elongated by pressing down the ejection button body. In the ejection button with a long nozzle that ejects forward from the ejection port at the tip, a cover body having both side walls that covers both side surfaces of the ejection button body is attached to the container head, and the ejection button body is attached to the ejection button body. A guide groove is formed before and after the upper end of the central flow passage portion, extends in the front-rear direction, and communicates with the central flow passage portion, and has a closed rear end, and the long nozzle is sealed in the guide groove. Guided to slide The slide pipe has a distal end connected to the distal end of the slide pipe and extending along the slide pipe, thereby covering the upper surface of the injection button body and being guided by the side wall so as to be slidable in the front-rear direction. When the slide operation piece is slid forward, the slide pipe is set to the use position in conjunction with the slide operation piece, the upper surface is opened, and the upper surface is pressed down. In addition, the injection is performed from the injection port at the tip of the slide pipe via the central flow path, the guide groove, and the inside of the slide pipe.
[0007]
In the non-use state, the slide pipe is housed in the guide groove, and the slide operation piece covers the upper surface of the injection button main body, so that the push-down operation cannot be performed. At the time of use, when the slide operation piece is slid forward, the slide pipe protrudes forward from the container peripheral surface, and the upper surface portion of the injection button main body is opened so that the push-down operation can be performed.

A guide pipe 15 forming a guide groove is fitted into the storage groove, and the length thereof is set to a value after the storage groove 13 in a state where the flange-shaped head portion 15a is in contact with the distal end peripheral surface of the storage groove 13. The length is set to leave a gap 15c at the end. The front half of the guide pipe 15 is engaged with the peripheral surface of the storage groove 13 in a sealed state, and the projection is locked in the engagement groove 13a. In addition, the outer diameter of the rear half of the separate guide pipe 15 is reduced, so that an annular flow path 15b communicating with the gap 15c can be formed between the inner peripheral surfaces of the storage grooves 13.
[0011]
The cover body 20 covers the shoulder of the aerosol container 1 and the circumference of the mounting cup 2 by externally fitting to the fastening portion 4a, and covers the side surface of the injection button body 10 following the cylindrical base portion 21 and the upper portion thereof. It has side walls 22 on both sides. As shown in FIG. 3, the side wall portion has an outer peripheral surface 22a having the same curved surface as the base portion 21 and an inner peripheral surface having a flat surface parallel to each other along both side surfaces of the transverse flow path portion 16 with a gap. 22b, and an upper surface portion 22c that covers a space formed by these. Flanges 24 and 24b are formed before and after the upper portion of the base 21 to partially connect between the side walls 22 on both sides. The front flange portion 24 is connected to the lower end of the peripheral surface portion 14 at the front of the injection button main body 10 via an integral hinge portion 24a. That is, the injection button body 10 is formed integrally with the cover body 20 by a synthetic resin in a swingable manner.
[0012]
The long nozzle 30 includes a slide pipe 33 which is slidably housed in the guide pipe 15 in a sealed state, an injection port member 32 having an injection port 31 by engaging a distal end thereof, and an inner pipe at an upper end of the cover body 20. It is composed of a plate-shaped slide operation piece 35 that is slid forward and backward along stepped guide rails 25 on both sides formed at corners of the peripheral surface 22b and the upper surface portion 22c. By engaging an engagement groove 32a formed on the outer periphery of the nozzle member 32 with an engagement hole 36a formed in the front portion 36 bent at the front end into an L shape, the nozzle member 32 can be slid. It is assembled to the piece 35.
[0013]
Thus, in a state where the slide pipe 33 is stored in the guide pipe 15, the slide operation piece 35 extends along the slide pipe 33 to which the distal end is connected, and covers the upper surface portion 18 of the injection button body 10. I do. A recess 35 a for setting a finger is formed at the rear end of the slide operation piece 35. Further, on both sides of the rear end of the slide operation piece 35, a projection 39 which slides along a guide groove 25a provided on the side surface of the guide rail 25 is formed, and is restricted by a stopper 25b formed at a front end of the guide groove 25a. It is supposed to be.
[0014]
The operation of the injection button with the long nozzle configured as described above is as follows. In the non-use state shown in FIGS. 1 and 2, the injection port member 32 occupies a position slightly protruding forward from the peripheral surface of the aerosol container 1, and the rear end of the slide pipe 33 occupies the rear end position of the guide pipe 15. At the same time, the entire area of the upper surface portion 18 of the cross flow path portion 16 is covered by the slide operation piece 35, and the pressing operation thereof cannot be performed.
[0015]
At the time of use, as shown in FIG. 4, as shown in FIG. 4, the slide operation piece 35 is pushed forward by putting a finger on the concave portion 35 a and advanced until the projection 39 is restrained by the stopper 25 b formed at the front end of the guide groove 25 a. The slide pipe 33 moves forward while being guided by the guide pipe 15 in a sealed state, and the injection port member 32 is set at a position protruding forward from the peripheral surface of the aerosol container 1 by a length corresponding to a substantial diameter thereof.
