Description

[Detailed description of the invention] (Industrial application field) This invention attaches to an elastically deformable container such as a plastic bottle and presses the container so that the content liquid can be metered and poured into the measuring chamber. Related to the measuring cap.

(Prior Art) Conventionally, various types of measuring caps for dispensing a constant amount of a solution in a squeeze bottle are known, and are roughly classified into types in which a measuring chamber is located in a bottle mouth (for example, Japanese Patent Publication No. 63-44630).
JP, JP-A-61-99568), those located outside the bottle mouth (for example, JP-B-63-30700, JP-B-63-3)
No. 5973). These conventional measuring caps,
The measuring chamber has a double wall for assembly, making it difficult to observe the inside of the measuring chamber, and has a problem in that the structure is complicated and molding, assembling, or capping to a container is troublesome.

In addition, in any conventional squeeze bottle, the liquid outlet of the pouring pipe for pouring the liquid into the measuring chamber is always open, and by pressing the bottle, the content liquid is always supplied to the measuring chamber. Can be poured out. For this reason, the content liquid is poured into the measuring chamber by an inadvertent pressing due to vibration during transportation, collapse of the load, or the like. As a result, a state in which the liquid has accumulated in the measuring chamber is observed from the outside, resulting in poor appearance, which not only reduces the commercial value, but also has a disadvantage that the liquid is dried to lower the measuring accuracy.

(Problems to be solved by the present invention) The present invention was created to solve the above-mentioned drawbacks of the conventional measuring cap, and the liquid was inadvertently poured into the measuring chamber during transportation or during display. Without being molded,
It is an object of the present invention to provide a measuring cap which is easy to assemble and to cap on a container.

(Means for Solving the Problems) To achieve the above object, a measuring cap according to the present invention includes a cap body having a bottle engaging portion and a measuring chamber formed above the bottle engaging portion, and a separate body from the cap body. And a lid member having a cover lid integrally formed with the inner lid and a hinge via the inner lid and a hinge fitted to the upper portion of the peripheral wall of the measuring chamber of the cap body. A discharge pipe having a lower end opened and a liquid outlet provided in the vicinity of an upper end portion is formed in the chamber bottom wall so as to protrude therefrom. An outlet is formed,
In addition, the problem is solved by a configuration in which the lid member is formed with a cylindrical liquid outlet plug that is fitted to an upper end portion of the pouring tube and closes the liquid outlet.

As an attachment form of the liquid outlet plug to the lid member, an appropriate means such as protruding molding on the inner surface of the cover lid or detachably provided inside the liquid injection port of the inner lid can be adopted.

(Operation) When the cover lid is provided with a liquid outlet plug, the liquid outlet plug always closes the liquid outlet of the pouring tube when the cover lid is closed. Further, when the liquid outlet plug is detachably provided on the inner lid, the liquid outlet plug closes the liquid outlet of the pouring tube unless the liquid outlet plug is disconnected. Therefore, in these states, even if the bottle is pressed, the content liquid is not poured into the measuring chamber. Therefore, even if the bottle is pressed by a shock during transportation, the liquid does not jump out into the measuring chamber, and the measuring chamber is not contaminated with the liquid until the consumer uses it. I do not.

In use, when the cover lid is opened or the liquid outlet plug is separated from the inner lid, the liquid outlet of the discharge pipe is opened, and the liquid can be discharged. By squeezing the bottle in this state, the internal solution is sucked up into the measuring chamber through the pipe. When the liquid in the measuring chamber reaches the level up to the liquid outlet of the discharge pipe, excess liquid returns to the bottle when the bottle is restored to its original shape. The liquid of the volume up to the lower end is stored, and can be dispensed quantitatively.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.
