The metering cap 4 is pulled upward while rotating counterclockwise. When the rotation of the measuring cap 4 advances and the measuring cap 4 moves upward, the screwing of the female screw portion 42a and the male screw portion 3a is released. At this time, the female screw portion 42 a is screwed only with the finger hook portions 11 and 12.

  Furthermore, when the rotation of the measuring cap 4 proceeds, the screwing between the female screw portion 42a and the finger hook portions 11 and 12 is released. Since the finger hooks 11 and 12 are disposed 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 stopper 6 is exposed, the fingers are hooked on the finger hook portions 11 and 12 of the inner stopper 6 to rotate the inner stopper 6 in the circumferential direction. The rotation direction may be either left rotation or right rotation. For example, when the inner plug 6 rotates clockwise and moves in the circumferential direction, the side surface 21a of the first engagement convex portion 21 moves along the side surface 61a of the first engagement concave portion 61 as the inner plug 6 moves. The side surface 22a of the second engagement convex portion 22 moves along the side surface 62a of the second engagement concave portion 62 and is guided upward. The movement of the first engagement convex portion 21 and the second engagement convex portion 22 is performed at the same timing and the same locus.

  Thereby, as shown in FIG.13 and FIG.14, the inner stopper 6 moves to the upper side (+ Z side) with respect to the opening | mouth part 3. FIG. As described above, when the inner stopper 6 moves upward in the circumferential direction, the inner stopper 6 is moved to the mouth 3 (container body 2 by moving the fingers holding the finger hooks 11 and 12 upward. ) Can be removed.

  Since the finger hooks 11 and 12 are arranged at intervals of 180 ° with the axis C interposed therebetween, the finger hooks 11 and 12 can be removed in a balanced state without the inner plug 6 being inclined. Further, since the finger hooks 11 and 12 are provided to protrude radially outward from the flange portion 32 of the inner plug 6, the contents do not adhere to the fingers on the fingers hooked on the finger hooks 11 and 12. The stopper 6 can be detached from the mouth 3.

  When the inner plug 6 is removed and the opening 3 is opened, for example, the contents can be replenished from the refill container into the container body 2 through the opening 3. Since the opening of the mouth portion 3 has a large diameter with respect to the nozzle 34 and the communication portion 36, the replenishment of the contents can be performed easily and quickly.

Next, a procedure for mounting the removed inner plug 6 to the container body 2 will be described.
The inner plug 6 with the fingers 11 and 12 gripped by fingers is inserted into the opening of the mouth portion 3 from the bottom wall portion 33, and the first engagement convex portion 21 and the second engagement convex portion 22 are connected to the first engagement portion. Insert into the mating recess 61 and the second engagement recess 62, respectively. At this time, since the circumferential position of the finger hanging portion 11 is the same as that of the first engaging convex portion 21 and the circumferential position of the finger hanging portion 12 is the same as that of the second engaging convex portion 22, The first engagement convex portion 21 and the second engagement convex portion 22 can be easily inserted into the first engagement concave portion 61 and the second engagement concave portion 62 using the positions of 11 and 12 as indices.

  Further, with respect to the circumferential direction, the maximum length L1 of the first engagement convex portion 21 is longer than the maximum length L4 of the second engagement concave portion 62, and the first engagement convex portion 21 becomes the second engagement concave portion 62. Since the insertion is impossible, it is possible to avoid an erroneous assembly in which the first engagement convex portion 21 is inserted into the second engagement concave portion 62 and the second engagement convex portion 22 is inserted into the first engagement concave portion 61.

Further, the circumferential position of the first engaging convex portion 21 and the second engaging convex portion 22 is shifted, and the side surface 61 a of the first engaging concave portion 61 and the second engaging concave portion 62 are shifted from the upper surface of the mouth portion 3. It is assumed that the side surface 62a may be slid.

  In this case, the difference between the maximum length L1 of the first engagement convex portion 21 and the maximum length L2 of the first engagement concave portion 61 is the maximum length L3 of the second engagement convex portion 22 and the second engagement concave portion. 62, the radius r1 of the side surface 21a of the first engagement convex portion 21 and the radius r3 of the side surface 22a of the second engagement convex portion 22 are the same. Furthermore, since the radius r2 of the side surface 61a in the first engagement recess 61 and the radius r4 of the side surface 62a in the second engagement recess 62 are the same, the top surface of the mouth portion 3 by the first engagement convex portion 21 is illustrated. The movement of the first engagement recess 61 shown in FIG. 11 to a predetermined position, and the movement of the second engagement protrusion 22 from the upper surface of the mouth 3 to the predetermined position of the second engagement recess 62 shown in FIG. Are performed with the same timing and the same movement trajectory. For this reason, when at least one of the movement timing and the movement locus is different, it is possible to prevent the inner plug 6 from being inclined and causing troubles such as hindering insertion into the mouth portion 3.

  When the first engaging convex portion 21 is inserted into the first engaging concave portion 61 and the second engaging convex portion 22 is inserted into the second engaging concave portion 62, the inner plug 6 is moved downward via the finger hook portions 11 and 12. The push fitting part 37 is fitted to the inner peripheral surface 3 b of the mouth part 3. Thereby, the inner stopper 6 is attached to the container main body 2 (mouth part 3).

  When the inner plug 6 is attached to the container main body 2 (mouth 3), the measuring cap 4 is rotated to the right, and the female screw portion 42a and the finger hooks 11 and 12 in the measuring cap 4 are screwed together. When the rotation of the measuring cap 4 proceeds and the measuring cap 4 moves downward, the female screw portion 42 a is screwed with the male screw portion 3 a of the mouth portion 3. At this time, since the measuring cap 4 rotates in a state of being screwed to the finger hook portions 11 and 12 disposed in the extension regions 51a and 52a of the male screw portion 3a, the female screw portion 42a is smoothly screwed to the male screw portion 3a. Then, the initial state shown in FIG. 1 can be obtained by further rotating the measuring cap 4 to engage with the container main body 2 (mouth 3) from above.

  As described above, in the container 1 with a measuring cap of the present embodiment, the finger hook portions 11 and 12 are provided on the radially outer side of the flange portion 32 of the inner plug 6, and the periphery of the inner plug 6 with respect to the mouth portion 3 is provided. As the direction moves, the first engaging convex portion 21 and the second engaging convex portion 22 of the inner plug 6 are guided upward by the side surface 61a and the side surface 62a, so that the contents adhere to the fingers. It is easy to remove the inner plug 6 by moving it upward.

  Moreover, in the container 1 with a measuring cap of this embodiment, since the finger hook parts 11 and 12 do not protrude outside the extension regions 51a and 52a of the male screw part 3a, the finger hook parts 11 and 12 are flange parts. Even if protruding outward in the radial direction of 32, it is possible to avoid hindering the attachment / detachment of the measuring cap 4 to / from the container body 2.

  Moreover, in the container 1 with a measuring cap of this embodiment, since the external thread part 3a is formed with the multi-threaded screw, it is possible to provide the several finger hook part 11 and 12.

  Further, in the container 1 with the measuring cap of the present embodiment, the first engagement convex portion 21 and the second engagement convex portion 22 provided in the inner stopper 6 are provided with the first engagement concave portion 61 provided in the mouth portion 3. And the second engaging recess 62 respectively, the inner plug 6 can be easily positioned in the circumferential direction with respect to the container body 2. For example, the opening of the nozzle portion 34 has a predetermined position in the circumferential direction. Can be prevented from being arranged at different positions. Furthermore, in the container 1 with a measuring cap of the present embodiment, the first engagement convex portion 21 has a maximum length L1 longer than a maximum length L4 of the second engagement concave portion 62 in the circumferential direction. The convex portion 21 is not inserted into the second engaging concave portion 62. Therefore, in the present embodiment, it is possible to avoid an erroneous assembly in which the first engagement convex portion 21 is inserted into the second engagement concave portion 62 and the second engagement convex portion 22 is inserted into the first engagement concave portion 61.

  In addition, in the container 1 with the measuring cap of the present embodiment, the difference between the maximum length L1 of the first engagement convex portion 21 and the maximum length L2 of the first engagement concave portion 61 is the second engagement convex portion 22. Is equal to the difference between the maximum length L3 and the maximum length L4 of the second engagement recess 62, and the radius r1 of the side surface 21a of the first engagement protrusion 21 and the second engagement protrusion 22 The radius r3 of the side surface 22a is the same, and the radius r2 of the side surface 61a in the first engagement recess 61 and the radius r4 of the side surface 62a in the second engagement recess 62 are the same. Therefore, when the inner plug 6 is removed, when the inner plug 6 is moved (rotated) in the circumferential direction, the first engagement convex portion 21 is guided upward by the first engagement concave portion 61, and the first The trajectory of the second engagement convex portion 22 directed upward by being guided by the two engagement concave portions 62 can be made the same. Further, when the inner plug 6 is attached, the first engagement convex portion 21 moves from the upper surface of the mouth portion 3 to the predetermined position of the first engagement concave portion 61, and the second engagement convex portion 22 causes the upper surface of the mouth portion 3 to move. To the predetermined position of the second engaging recess 62 can be made the same timing and the same movement locus.

  Therefore, in the container 1 with a measuring cap of the present embodiment, it is possible to prevent problems such as tilting of the inner plug 6 when the inner plug 6 moves in the Z direction when the inner plug 6 is removed and attached. Moreover, in the container 1 with a measuring cap of this embodiment, since the side surface 61a of the 1st engagement recessed part 61 and the side surface 62a of the 2nd engagement recessed part 62 are formed in the circular arc shape by which the curvature center was arrange | positioned at the upper side.
