Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a discharge amount adjusting inner plug provided at an extraction port formed in a container for accommodating a liquid material and adjusting the discharge area of the liquid material by changing the opening area of the extraction port. About.

[0002]

2. Description of the Related Art Liquid substances such as lotion, milky lotion, and liquid detergent contained in a container can be extracted from the extraction port by removing a cap of the extraction port and turning the container upside down at the time of use. Has become. An opening set to an assumed discharge amount is formed in the extraction port, and the amount of extraction of the liquid material is adjusted by the opening.

However, in some cases, the amount of liquid material to be extracted may be large or small depending on the use of the liquid material. Therefore, it is preferable that the amount of liquid can be adjusted. A structure with a variable amount is disclosed. That is, in this discharge amount variable structure, the opening degree is changed by covering the opening formed in the rotating inner plug with the fixed plate provided in the extraction port.

[0004]

However, in such a conventional variable discharge amount structure, the rotating inner plug is supported by a fixed plate, and the center of the inner plug and the fixed plate is rotated. It is rotatably supported via a moving shaft. For this reason, the opening formed in the inner plug is formed at the peripheral edge thereof, avoiding the center portion which is rotatably supported.

As described above, since the center portion of the inner plug is closed by the rotation supporting portion, an opening cannot be formed in the center portion of the inner plug, so that the opening ratio is reduced, and a predetermined opening area is secured. As a result, the inner plug becomes larger in diameter as a whole, and the inner plug becomes larger.

In view of the foregoing, the present invention has been made in view of the above-mentioned conventional problems, and makes it possible to increase the aperture ratio of an opening area by effectively utilizing a central portion and to smoothly extract a discharged liquid material. It is an object of the present invention to provide an inner plug for adjusting a discharge amount.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a discharge apparatus for adjusting the discharge amount of a liquid material by changing the opening area of an extraction port formed in a container for storing the liquid material. In the volume adjusting inner plug, an inner plug main body attached to the extraction port, a central opening provided in the inner plug main body, having a central opening communicating with the inside of the container at a central portion, and a peripheral opening around the central opening. A weir plate having an opening for opening and closing partially in the direction, a rotating nozzle rotatably mounted on the inner plug main body, and a central through hole provided in the rotating nozzle and having a central portion that is always in communication with the central opening. A shutter plate slidably rotated on the dam plate by the rotation of the rotary nozzle to increase or decrease the opening degree of the opening / closing opening.

According to this structure, the central opening and the central through-hole are formed at the center of the weir plate and the shutter plate, and the central opening and the central through-hole are always communicated with each other. Thus, an opening having a considerable opening area can be secured. On the other hand, when the rotating nozzle is rotated by rotating the rotating nozzle, when the rotating nozzle is rotated, the opening of the opening / closing opening formed in the weir plate of the rotating stopper is mounted on the inner opening body in which the rotating nozzle is rotatably mounted. Is changed, and the discharge amount can be adjusted.

Further, a stopper is provided between the inner plug body and the rotary nozzle for stopping the rotation of the rotary nozzle at the fully open position and the fully closed position of the opening / closing opening.

According to this configuration, when the rotary nozzle is stopped rotating by the stopper at the fully closed position, the minimum discharge amount is obtained,
The maximum discharge amount is obtained when the rotation is stopped by the stopper at the fully open position. Therefore, since the minimum discharge amount and the maximum discharge amount can be automatically determined at the rotation stop position of the rotary nozzle, the operability of discharge amount adjustment can be improved.
