Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid pouring stopper for refilling a small container, which is provided so as to be attached to a large container for containing a liquid such as a beverage or a seasoning.

[0002]

2. Description of the Related Art Recently, a supporting cylinder is erected from a base cylinder that is fitted in a liquid-tight manner to the neck of a container body, and a holding cylinder having front and rear end face openings is attached to the upper end of the supporting cylinder so as to communicate with the inside of the supporting cylinder. With the plug body,
A member with a handle in which the nozzle middle part of the rear end face is closed is inserted into the holding cylinder in a liquid-tight manner, and a handle is projected outward from the rear part of the nozzle, and is attached to the stopper body via a strip-shaped part. It consists of a palate that is detachably fitted to the front end of the nozzle. When the handle is tilted to one side and the nozzle is rotated with respect to the holding cylinder, a through hole provided in the nozzle and a liquid introduction hole at the upper end of the support cylinder are formed. And the liquid inside the container flows out from the nozzle, and when the handle is turned and tilted to the other side, the nozzle rotation causes the above-mentioned through hole and liquid introduction hole to be blocked and the liquid to stop flowing. In addition, a pawl is fitted to the tip of the nozzle after the outflow of the liquid to prevent dust and the like from entering and keep the inside of the nozzle clean. In such a liquid pouring stopper, if a handle that touches another object during transportation stands up from the stopper body, it may become bulky or the handle may break, so at the time of shipment from the factory, a separate stopper is elastically deformed to stop the stopper. It is fitted to the body and the handle is locked in the closed position.

[0003]

By the way, since the stopper is a specification for transportation and is thrown away after the liquid spouting plug is attached to the mouth and neck, the above-mentioned conventional liquid spouting plug after attachment has a different property. May touch the handle and open the cap. Therefore, when transferring the liquid in the container to the refill container, the liquid may spill if the palate is removed without noticing the opening, or if the opening is noticed and the handle is returned to the closed position, the palate should be removed. However, there is a drawback that the liquid accumulated in the nozzle spills though it is a small amount. In order to solve this drawback, it is sufficient to fit the stopper main body at the time of closing without discarding the stopper, but in this case, it is necessary to store it in a storage place so that a separate stopper removed from the stopper main body at the time of opening is not lost. It must be noted that, after the stopper is closed, it is necessary to fit the palate and then the stopper, which causes a troublesome and troublesome problem.

According to a first aspect of the present invention, a liquid pouring plug has a plug main body in which a nozzle projects forward from a peripheral edge of a through hole formed in an intermediate portion of the main cylinder, and an inner cylinder rotatable on the inner surface of the main cylinder. And a member with a handle in which the top plate of the inner cylinder is attached to the front end of the handle extending forward through a thin hinge, and the top plate of the inner cylinder is fitted to the outer surface of the front end of the nozzle after the lid is closed. Thus, the handle is locked to prevent accidental opening, and the palate does not obstruct the pouring liquid when opening.

According to a second aspect of the present invention, a liquid pouring plug is provided with a plug main body having a nozzle projecting forward from a peripheral edge of a through hole formed in an intermediate portion of the main cylinder, and a transparent main body having an intermediate hole formed in the main cylinder. The nozzle projects forward from the peripheral edge of the hole, and a rotatable inner cylinder is fitted to the inner surface of the main cylinder. The inner cylinder extends in any direction other than the front of the top plate to form a handle. It is composed of a member with a handle with a palate attached to the front end of the elastically deformable strip that protrudes forward, and the handle is locked by accidentally fitting the palate to the outer surface of the front end of the nozzle after closing the cap. Prevent the opening and make sure that the palate does not obstruct the pouring liquid when opening.

According to a third aspect of the present invention, the inner cylinder is fitted to the main cylinder when the palate is fitted to the front end of the nozzle, to the lower end of the inner cylinder and the inner wall surface portion of the main cylinder fitted to the lower end of the inner cylinder. From the position, the stoppers that engage with each other are provided at both ends of the rotation range where the inner cylinder can be rotated until the second through hole and the base end through hole of the nozzle communicate with each other, and the handle is rotated without positioning the handle. So that it can be adjusted to the open position and the closed position.
