[0019]
Next, the function and effect of the liquid ejection container of the present invention will be described.
When the liquid ejection container is used, the contents are ejected by directing the container mouth 1 downward in a desired direction and pressing the weight of the content liquid or the body 2.
When the open / close lid B3 is opened and the container A is tilted when the content liquid is ejected, a shocking hydraulic pressure is applied to the inner surface of the upper wall 5 of the cap B due to the water hammer action of the content liquid. Since the shielding plate 26 is provided, the content liquid collides with the shielding plate 26 and flows in the lateral direction, and no shocking liquid flow is transmitted to the dispensing opening 12.
Therefore, when the container A is tilted, the content liquid does not temporarily jump out.
[0020]
When the container opening 1 is directed downward, as shown in FIG. 4, the opening valve 15 is opened by the weight of the content liquid to form a conical cylindrical opening, and the content liquid is formed on the conical surface of the conical valve section 16. Along the ring.
When the opening valve 15 is opened to the lowermost end and the opening is wide, air is introduced from a part of the opening, so that ejection is continued.
Then, as the fall occurs, the conical cylinder ring is divided, converged into a trickle, and falls into a shower shape.
[0021]
When a large amount of content liquid is ejected, when the body portion 2 is pressed, the content liquid is ejected from a conical cylindrical opening in a ring shape or a shower shape.
When the pressing of the body part 2 is stopped, the ejection of the content liquid stops, the body part 2 is restored, and the inside of the container becomes low pressure, whereby air is introduced from the conical cylindrical opening, and the next pressing and ejection of the content liquid Will be prepared.
[0022]
When the container A is erected after the ejection and the open / close lid B3 is closed, the opening valve 15 is pressed by the pressing ring 33, so that the opening valve 15 is not opened even if the container A is laid down or inverted.
[0023]
Next, examples of the dispensing opening and the opening valve will be described.
In the above embodiment, the dispensing opening is formed as a conical cylindrical opening and ejected in a ring shape, but in this embodiment, the dispensing openings are ejected in two rows inside and outside and ejected in a double shower shape. It is what I did.
[0024]
As shown in FIGS. 5 and 6, the conical valve seat 13 of the dispensing opening 12 is provided with protrusions 40 at equal intervals in the circumferential direction, and the conical valve 16 of the opening valve 15 has A concave groove 41 with which the protrusion 40 engages is engraved.
The height of the protrusion 40 is such that the crest surface 40a is located in the concave groove 41 even when the opening valve 15 is opened.
The space | interval, height, and width | variety of the protrusion 40 and the protrusion 40 can be selected suitably, and can change the position of a jet nozzle by it.
[0025]
As shown in FIG. 6, when the opening valve 15 is opened, the liquid content is between the peak surface 40 a of the ridge 40 and the valley surface 41 a of the groove 41, and between the conical valve seat 13 between the ridges 40. It is ejected from between the conical valve part 16 and is ejected as a double shower inside and outside.
[0026]
In the above embodiment, if the peak surface of the protrusion 40 is lowered, the pour opening will be continuously U-shaped on the inside and outside, and will be ejected as a shower with a width between the inner and outer circumferences. The
Moreover, in the said Example, although the protrusion 40 and the concave groove 41 were combined, it is not restricted to this, As shown in FIG. By changing the shape, it is possible to obtain various shapes and other shower-like jets.
[0027]
【The invention's effect】
Since this invention is comprised as mentioned above, there exists the following effect.
Since the opening valve support member is provided with a blocking plate for the dispensing opening, the liquid flow caused by the water hammer action can be prevented from being transmitted to the dispensing opening.
