However, the conventional measuring cap has the following problems.
For example, when pouring the contents into the measuring cup, the relative position and posture of the container side where the cap body is attached and the measuring cup are not stable, and the contents cannot be poured into the measuring cup with high accuracy. Or the contents spilled out of the measuring cup. In particular, when the contents are filled in the container and relatively heavy, or when the operator's force is weak, the position of the spout with respect to the measuring cup fluctuates and the operation is easy to make.
Further, it may be possible to stabilize the mutual position by bringing the measuring cup into contact with the dispensing cylinder, but in this case, it is difficult to accurately determine the position of the outlet with respect to the measuring cup.

  This invention is made | formed in view of such a situation, The objective is to provide the measuring cap which can pour the contents into a measuring cup accurately.

In order to solve the above problems, the present invention proposes the following means.

When removing and injecting the contents from the spout of the spout tube into the measuring cup, the diameter of the other end of the peripheral edge of the cap body and the outer peripheral surface of the peripheral wall of the measuring cup Direction And it is characterized in that it is formed to be brought into contact from the side.

According to the measuring cap according to the present invention, since the recess is formed in at least one of the opening edge of the peripheral wall portion of the cap body and the outer peripheral surface of the peripheral wall portion of the measuring cup, the measuring cup is removed from the cap body. When the contents are poured into the measuring cup from the spout of the dispensing cylinder, the cap body and the measuring cup are brought into contact with each other by bringing the wall defining the recess into contact with the other from the outside in the radial direction. Contact at a plurality of points, line contact, or surface contact can be performed, and the cap body and the measuring cup can be relatively positioned.
From the above, when injecting the contents from the spout into the measuring cup, it becomes possible to stabilize the relative position and posture between the container side on which the cap body is mounted and the measuring cup, and the contents are put into the measuring cup. Can be poured accurately.

  Further, the wall surface defining the recess may be a concave curved surface having a radius of curvature equal to or greater than the other outer radius.

Therefore, when the contents are poured into the measuring cup from the spout, it is possible to reliably stabilize the relative position and posture between the container side on which the cap body is mounted and the measuring cup.

  The dispensing cylinder is formed with a slit extending in the direction of the central axis of the cap body, and the portion located on the opposite side of the slit with the central axis in the radial direction at the outlet is the central axis. It may be a sharpened portion that protrudes outward in the radial direction as it goes outward in the direction.

In this case, since the said slit is formed in the extraction pipe | tube, when extracting content, the content can be poured out, making air approach into a container from a slit. Therefore, the contents can be easily poured out, and the accuracy of weighing the contents poured into the measuring cup is ensured.
In addition, by pouring the contents along the sharpened portion, the contents can be easily guided into the measuring cup, and the contents can be prevented from jumping to the outside in the radial direction of the measuring cup.

  Moreover, the said recessed part may be formed in the position corresponding to the said sharp part along the circumferential direction in the opening edge part of the surrounding wall part of the said cap main body.

  In this case, since the concave portion is formed at a position corresponding to the sharpened portion along the circumferential direction at the opening edge portion, when the content is poured into the measuring cup from the spout of the spout tube while being measured. It is possible to relatively position the measuring cup and the cap body so that the sharpened portion protrudes toward the inside of the measuring cup by simply bringing the wall defining the recess into contact with the outer peripheral surface of the measuring cup. Become. Therefore, when pouring the contents from the spout into the measuring cup, the contents can be poured into the measuring cup with high accuracy while facilitating the relative positioning of the measuring cup and the cap body.

  According to the measuring cap according to the present invention, the contents can be poured into the measuring cup with high accuracy.
