こうした従来の噴出ヘッドは、ヘッド本体に設けられた突出部に条溝を形成し、この突出部外周にノズルチップの周壁内側を嵌合させることで、開孔に通じる流路を形成しているが、例えば、内容物を噴霧するときに、条溝と流路の位置によっては、霧の状態や噴霧角度等によって規定される噴射パターンが安定しないことがあった。   In such a conventional ejection head, a groove is formed in a protrusion provided in the head body, and a flow path leading to the opening is formed by fitting the inner periphery of the nozzle tip to the outer periphery of the protrusion. However, for example, when spraying the contents, depending on the position of the groove and the flow path, the spray pattern defined by the fog state, the spray angle, and the like may not be stable.

本発明の目的とするところは、噴射パターンの安定した噴射ヘッドを提供することにある。   An object of the present invention is to provide an ejection head having a stable ejection pattern.

Each of the two grooves 4g 1 is connected to a spin groove 4g 2 formed in the partition 4a as shown in FIG. Thereby, each of the spin channels P 2 communicating with the opening A 3 communicates with each of the two inflow channels P 1 as described above.

加えて、環状流路Ｐ4は、図４に示すように、中間部材４の隔壁４ａに形成された環状溝４ｇ4で形作られている。環状溝４ｇ4は、２つの条溝４ｇ1を連通させる。これにより、流入路Ｐ1及びスピン流路Ｐ2はそれぞれ、上述のとおり、環状流路Ｐ4を通して一体に連通する。 In addition, as shown in FIG. 4, the annular flow path P 4 is formed by an annular groove 4 g 4 formed in the partition wall 4 a of the intermediate member 4. The annular groove 4g 4 allows the two groove grooves 4g 1 to communicate with each other. As a result, the inflow channel P 1 and the spin channel P 2 communicate with each other through the annular channel P 4 as described above.

更に、中間部材４の周壁４ｂには、その内側に形成された空間Ｃに通じさせる２つの貫通孔Ａ2が形成されている。２つの貫通孔Ａ2はそれぞれ、２つの条溝４ｇ1それぞれと連通する。 Furthermore, two through holes A 2 are formed in the peripheral wall 4 b of the intermediate member 4 so as to communicate with the space C formed inside thereof.
