DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for selecting one of a plurality of preset dispensing amount values for a content liquid contained in a container body having squeezability, and selecting the selected amount. The present invention relates to a metering / dispensing cap for measuring / dispensing a content liquid.

[0002]

2. Description of the Related Art A technique disclosed in Japanese Utility Model Laid-Open Publication No. Sho 62-093079 discloses a technique in which a liquid content contained in a squeezable container body is measured to a desired constant amount and then discharged.

In this prior art, in a metering container comprising a plastic container main body, a cup-shaped measuring portion and a cap provided above the opening, the measuring portion is fitted into the opening of the container main body, and a pipe is provided at the lower end. A variable amount member capable of rotating the injection amount variable cylinder that can be densely rotated and slid on the outer periphery of the outflow cylindrical body rising in the center of the fixed amount member, and a variable amount member that can rotate the injection amount variable cylinder fitted into the outer periphery. The metering member has an upper horizontal disk body of a fitting cylinder fitted to the container opening, the outflow cylinder rises integrally at the center, and there is a positioning stopper at the base side wall base of the outflow cylinder, The upper part has two types of slits with different lengths. The variable discharge amount cylinder rises above the horizontal disk body of the fixed amount member, and is rotatably slidably fitted around the outflow cylinder body, and has a window at the lower part. And a stopper, from the upper edge down Opposite cuts corresponding to the slits are provided toward the outside, fitted from the top on the outside of the variable discharge amount cylindrical body, the top plate has a discharge amount variable member provided with a stepped central ridge. Has become.

In this apparatus, a variable discharge amount cylinder is rotated to one of two rotation limit positions set by a stopper, whereby the variable discharge amount cylinder is provided. Is aligned with one slit of the metering member, and the content liquid is weighed out in an amount corresponding to the height position of this one slit. This is achieved by rotating the variable quantity cylinder to the other rotation limit position.

[0005]

However, in the above-mentioned prior art, since only two weighing values can be set, the desired dispensing amount and the actual dispensing amount are different.
In some cases, the entire area of the upper surface of the weighing chamber is open during the setting change operation of the dispensing amount and during the weighing operation. There is a problem that it is necessary to pay attention to the pouring operation so as not to be scattered, and it is difficult to obtain a proper and preferable use condition because foreign substances such as dust may enter the measuring chamber.

[0006] In addition, a changeable dispensing member, which is a dedicated member, is required for switching the setting of the dispensing amount. This dispensing amount variable member becomes unnecessary when the content liquid is dispensed and dispensed. There was a problem that it was troublesome.

Accordingly, the present invention has been made in order to solve the above-mentioned problems in the prior art, and it is possible to set two or more weighing values of the dispensing amount, and to set the inside of the main body of the dispensing cap. While forming a measuring chamber, from outside this measuring chamber,
The technical task is to make it possible to switch the setting of the weighing value, so that it is possible to select and set a weighing value close to a desired dispensing amount, and to obtain simple and proper handling and a favorable use situation. Aim.

The upper surface of the weighing body is partially covered with the top plate of the cap body having the pouring cylinder piece opened upright, so that the liquid content scatters to the outside during the weighing operation and foreign matter such as dust is weighed. There is no risk of entering the body.

The switching of the setting of the dispensing amount can be achieved only by rotating the knob head of the switching body without requiring a separate dedicated member, so that the handling is extremely simplified.

According to a second aspect of the present invention, a mark is provided on the top surface of the top plate adjacent to the picking head of the switching body as a guide for setting the switching rotation position according to the display of the switching body. is there.

According to the second aspect of the present invention, the setting of the dispensing amount can be easily and reliably switched by adjusting the display of the switching body to the mark on the top plate.

According to a third aspect of the present invention, there is provided a step for mounting the main body cylinder of the measuring body on the lower half of the container main body, which is closely fitted into the mouth cylinder, and on the upper end surface of the container main body. The upper half is formed so as to extend continuously in diameter, and the upper end of the upper half is abutted against the lower surface of the top plate of the cap body.

According to the third aspect of the present invention, the state in which the weighing body is tightly fitted into the container body cylinder portion can be firmly held by the cap body.

According to a fourth aspect of the present invention, the knob head of the switching body is formed into a thick polygonal plate having the same number of corners as the number of the measuring spouts. It is configured so as to be located immediately above any one of the measuring spouts.

According to the fourth aspect of the present invention, when the setting of the dispensing amount is switched, the turning operation by gripping the knob head piece is performed.
It can be done easily and reliably.
