The difference between the maximum length L1 of the first engaging convex portion 21 and the maximum length L2 of the first engaging concave portion 61 in the circumferential direction is the maximum length L3 of the second engaging convex portion 22 and the second engaging. The difference from the maximum length L4 of the recess 62 is set to be the same. Since the above differences are the same, the locus from the upper surface of the first engaging convex portion 21 to the insertion into the first engaging concave portion 61 and the second engaging convex portion 22 are the mouth portion 3. The locus from the upper surface to the insertion into the second engaging recess 62 can be made the same.

Further, the circumferential length of the plane 21b connecting the lower ends of the side surfaces 21a on both sides of the first engaging convex portion 21 and the circumference of the plane 61b connecting the lower ends of the side surfaces 61a on both sides of the first engaging concave portion 61.

Therefore, the first engaging convex portion 21 cannot be inserted into the second engaging concave portion 62, and can be inserted only into the first engaging concave portion 61.

Next, in the container 1 with a measuring cap having the above configuration, a procedure for attaching and detaching the inner plug 6 to the mouth portion 3 (container main body) will be described with reference to FIGS. 4, 11 to 14.
As shown in FIG. 4, the finger hook portions 11 and 12 project radially outward from the flange portion 32 in a state where the male screw portion 3a is arranged in the extended region.

Further, the first engaging convex portion 21 projecting radially outward from the tubular portion 31 is inserted into the first engaging concave portion 61, and the second engaging convex portion 22 projecting radially outward from the tubular portion 31 is second. As shown in FIGS. 11 and 12, the inner plug 6 is positioned in the circumferential direction with respect to the container body 2 by being inserted into the engaging recess 62 and restricting the movement in the circumferential direction, respectively.

In this way, the female screw portion 42a is screwed with the male screw portion 3a from the initial state shown in FIG. 1 with respect to the container body 2 in which the inner plug 6 is mounted on the mouth portion 3 in the state of being positioned in the circumferential direction. Pull the measuring cap 4 upward while rotating it counterclockwise.

At this time, the female screw portion 42a is screwed only with the finger hook portions 11 and 12.

Further, as the rotation of the measuring cap 4 progresses, the screwing between the female screw portion 42a and the finger hook portions 11 and 12 is released. Since the finger hook portions 11 and 12 are arranged in the extension regions 51a and 52a of the male screw portion 3a, the measuring cap 4 can be smoothly removed from the container body 2.

When the measuring cap 4 is removed from the container body 2 and the inner plug 6 is exposed, a finger is placed on the finger hook portions 11 and 12 of the inner plug 6 to rotate the inner plug 6 in the circumferential direction. The rotation direction may be either left-handed rotation or right-handed rotation. For example, when the inner plug 6 rotates clockwise and moves in the circumferential direction, the side surface 21a of the first engaging convex portion 21 moves along the side surface 61a of the first engaging concave portion 61 with the movement of the inner plug 6. The side surface 22a of the second engaging convex portion 22 moves along the side surface 62a of the second engaging concave portion 62 and is guided toward the upper side. The movements of the first engaging convex portion 21 and the second engaging convex portion 22 are performed at the same timing and at the same locus.

As a result, as shown in FIGS. 13 and 14, the inner plug 6 moves upward (+ Z side) with respect to the mouth portion 3. In this way, when the inner plug 6 moves upward as it moves in the circumferential direction, the inner plug 6 is moved upward by moving the finger holding the finger hooks 11 and 12 upward, so that the inner plug 6 is moved to the mouth 3 (container body 2). ) Can be removed.

Since the finger hooks 11 and 12 are arranged at intervals of 180 ° across the axis C, the inner plug 6 can be removed in a well-balanced state without tilting. Further, since the finger hooking portions 11 and 12 are provided so as to project radially outward from the flange portion 32 of the inner plug 6, the contents do not adhere to the fingers hanging on the finger hooking portions 11 and 12 and are inside. The stopper 6 can be detached from the mouth portion 3.

When the inner plug 6 is removed and the mouth portion 3 is opened, for example, the contents can be replenished from the refill container into the container main body 2 via the mouth portion 3.
