Therefore, by pressing down the pressing plate 42 while the container main body A is tilted or releasing the hand from the pressing plate 42, the content liquid can be poured out and stopped at a single touch instantly.
[0020]
Furthermore, by adjusting the pressing amount of the operation member E, the gap between the valve plate 37 and the upper wall 17 of the fitting cylinder portion C1 is adjusted, and the outflow amount can be adjusted.
Further, since the atmosphere is introduced from the air introduction hole 26, the inside of the container does not become negative pressure, and a large amount of content liquid is poured out from the dispensing hole 25 of the dispensing nozzle 21 without any trouble. Can do.
Further, when the cap C is rotated with respect to the inner plug B, the direction of the pouring nozzle 21 can be changed, and as shown in FIG. By operating E, the content liquid can be dispensed.
[0021]
When the content liquid has been dispensed, the inner stopper B is rotated to unscrew and remove from the container mouth 1, and the content liquid is put in from the refill container, and the inner stopper B is again attached to the mouth of the container body A. When screwed to 1, the liquid dispensing container can be used many times.
[0022]
Next, a second embodiment of the liquid dispensing container will be described.
In the present embodiment, a cap is attached to a container mouth by plugging.
Hereinafter, the difference will be mainly described.
[0023]
As shown in FIG. 8, the liquid dispensing container includes a container main body Aa, a cap Ca, a valve body Da, and an operation member Ea.
The container body Aa includes a mouth portion 1a and a shoulder portion 2a, and a trunk portion 3a and a bottom portion. A fitting protrusion 50 is provided on the outer periphery of the mouth portion 1a, and a neck ring 51 is provided below the fitting protrusion 50a. Is provided.
[0024]
As shown in FIGS. 8 and 9, the cap Ca includes a fitting cylinder part C1a and a dispensing cylinder part C2a. The fitting cylinder part C1a is formed on the inner peripheral surface of the outer cylinder 55 and the container mouth part 1a. An inner cylinder 56 that engages to the lower end and an upper wall 57 are provided.
The outer cylinder 55 is provided with a bulging ring 58 that engages with the fitting protrusion 50 of the mouth portion 1a at the lower end of the inner periphery, and a knob portion extending in the circumferential direction at a predetermined position on the outer periphery. 59 is continuously provided.

The root portion 62 of the knob portion 59 is provided with a notch groove 63 connected to the groove 60 of the upper wall 57, and when the knob portion 59 is pulled outward, the outer periphery of the outer cylinder 55 is cut through the notch groove 63. Further, the thin portion 61 at the bottom of the groove 60 is cut, and the outer cylinder 55 is cut off from the upper wall 57.
[0026]
The configuration and mutual relationship of the extraction cylinder part C1a, the valve body Da, and the operation member Ea of the cap Ca are the same as those in the first embodiment, and the same reference numerals are attached with the suffix “a”. Description is omitted.
[0027]
Next, usage modes and effects of the liquid dispensing container of the present embodiment will be described.
The liquid dispensing container of the present embodiment is assembled by fitting the cap Ca to the mouth 1a of the container main body Aa with a stopper after the content liquid is stored in the container main body Aa.
[0028]
In dispensing the content liquid, as in the first embodiment, the operation liquid Ea can be operated, and the content liquid can be poured out, stopped, and the amount dispensed can be adjusted by tilting the container body Aa.
[0029]
When it is desired to change the direction of the dispensing nozzle, the outer tube 55 is removed and the cap Ca and the container main body Aa are fitted together as shown in FIG. Since only the inner cylinder 56 is provided, the fitting is loosened and the direction of the dispensing nozzle can be changed.
Further, when all the contents have been poured out, the cap Ca can be removed, the contents liquid can be put in from the refill container, the cap Ca can be attached again, and the liquid dispensing container can be reused.
[0030]
【The invention's effect】
Since this invention is comprised as mentioned above, there exists the following effect.
The operation member that is linked to the valve body is attached, and the discharge channel is opened by pressing the pressing plate of the operation member, and the discharge channel is closed by releasing the hand. Liquid can be poured out and stopped.
[0031]
Moreover, since the pouring hole and the air introducing hole are provided in the pouring nozzle, a large amount of content liquid can be efficiently poured by introducing air simultaneously with the pouring.
[0032]
Since the cap can be rotated with respect to the container, the direction of the pouring nozzle can be changed, and the container can be laid down on a table and operated by operating the operation member. It was.
In addition, the cap was removed from the container mouth so that it could be easily attached, so that the liquid contents could be refilled and the liquid dispensing container could be reused for a long time.
