度を調節できるようにしてある。 This invention will be explained below with reference to the illustrated embodiment. Reference numeral 1 denotes a head body of a nozzle assembly according to this invention, in which an injection passage 11 is bored and a horizontal cylindrical beak 12 is projected on the front surface. The beak body 12 has a
The end of the injection passage 11 is bored. Reference numeral 2 designates a nozzle cap, a top wall 21 of which has an injection hole 22 axially bored therein, and a bottom wall 23 of which is rotatably fitted to the beak body 12 described above. 3 is an elastic valve body made of rubber or the like, which connects the end of the injection passage 11 and the injection hole 22.
inserted in between. Now, according to the illustrated example,
The entire circumferential surface of the head body 1 except for the beak body 12 is formed into a vertical cylindrical surface, but according to this invention, it is not necessarily necessary to form the entire circumferential surface into a vertical cylindrical surface, and it is not necessary to form the entire circumferential surface into a vertical cylindrical surface. It is sufficient that the front surface is formed on the vertical cylindrical surface 13. The end edge 24 of the skirt wall 23 of the nozzle cap is shaped to match the vertical cylindrical surface 13, as can be seen particularly in FIGS. 2 to 4. Thus, when the nozzle cap is rotated, the aforementioned end edge 24 of the nozzle cap moves back and forth under the guidance of the vertical cylindrical surface 13 of the head body, so that the opening degree of the injection valve by the elastic valve body 3 can be adjusted. be.

がある。 In addition, regarding the shape of the elastic valve body 3, there are some differences between the examples shown in FIGS. 1 to 3 and the examples shown in FIGS. 4 to 7. In other words, if we compare the former example and the latter example, both are similar in that notches 31 are provided at several locations on a thick disc, and a recessed hole 32 is bored in the center of the plate surface. However, the positions of the grooves 33 bored in the plate surface are different. In the latter example, the groove 33 is bored approximately in a tangential line with respect to the circle of the recessed hole 32, and therefore, the injection liquid entering from the groove 33 rotates in a whirlpool shape in the recessed hole 32 and exits from the injection hole 22. It has the characteristic of being sprayed.

いる弾性弁体3は当初の強圧状態、従つて、閉弁
状態から、回転後の非圧縮状態、従つて開弁状態
まで弁の開度を変化させることができる。 To explain in more detail the above-mentioned adjustment of the opening degree of the valve by rotating the axis of the nozzle cap 2, referring to FIGS. 3 and 4, X-Y is the center line of the nozzle portion. That is, since the end edge 24 of the skirt wall 23 of the nozzle cap 2 is formed in a shape that matches the vertical cylindrical surface 13 of the head body 1, the end edge 24 of the nozzle cap 2 is initially aligned with the right side of the center line X-Y. Edge 24 of skirt wall 23
is engaged with the vertical cylindrical surface 13 of the head body 1 over the entire area, the length of the hem wall 23 differs by the maximum value h, and therefore, if the nozzle cap 2 is rotated 90 degrees, The longest part of the skirt wall 23 overlaps the center line X-Y, and the entire nozzle cap 2 is pushed forward as shown on the left side of X-Y. Thus,
The elastic valve body 3 inserted between the end of the injection passage 11 and the injection hole 22 changes the valve opening from the initial high pressure state, ie, the valve closed state, to the non-compressed state after rotation, ie, the valve open state. The degree can be changed.

しても液もれや誤噴射が発生するおそれはない。 This invention is as described above, and by rotating the nozzle cap 2, the opening degree of the injection valve can be easily adjusted, so the valve is fully closed as shown on the right side of the X-Y line. Then, the injection passage 11
Therefore, even if the container containing the spray liquid is overturned or shaken violently during transportation, there is no risk of liquid leakage or erroneous spraying.

In this intermediate state, the valve is no longer closed until the internal pressure of the injection passage 11 increases to a certain extent, and the injection liquid starts to be discharged from the injection hole 22. In other words, injection begins only after a certain amount of pressure has accumulated inside.
Therefore, since atomization, which is injection under pressure, is performed from the beginning of injection, there is no dripping from the nozzle at the beginning of spraying, unlike in conventional atomizers. In conventional nozzles, the injection passage and injection hole are directly connected, so at least momentarily at the beginning of injection, the injection pressure is almost zero or close to zero. Dropping is likely to occur.

とができる。 This invention is also advantageous when applied to finger-push piston type atomizers that are used on a daily basis, mainly at home. That is, the finger-push piston type sprayer sucks up the injected liquid into the valve stem by a lifting stroke of a hollow valve stem crowned with a push button with a nozzle, and releases the sucked up liquid from the nozzle by a downward stroke. It's summery. In order to perform this suction and release action, a suction valve is installed in the cylinder at the lower end of the valve stem, and a release valve is installed at the upper end.
Each is provided with a check valve, but when this invention is applied, the elastic valve body 3 described above will be able to prevent the weak negative pressure even if the inside of the valve stem becomes negative pressure when the valve stem is pulled up. Since it is possible to keep the valve in the closed state, it is also used as the discharge valve, and therefore there is no need to provide a ball valve or other check valve on the upper part of the valve stem, which simplifies the piston mechanism with a valve. be able to.

などの優れた効果がある。 Thus, according to this invention, by operating the nozzle cap 2, the container can be kept tightly sealed when not in use, and leakage of the sprayed liquid can be completely prevented, and when the sprayer is in use, the spray can be maintained by operating the nozzle cap 2. By exerting an appropriate pressure accumulation effect in the passage, it is possible to prevent dripping at the initial stage of injection and to obtain a good mist. In addition, especially when applied to a finger-push piston type sprayer, the check valve at the upper part of the valve stem can be omitted, resulting in excellent effects such as the ability to simplify the injection mechanism.
