  • FIG. 18 is a diagram to be compared with FIG. 5 in the above-described comparative example.
  • the torque peak P shown in FIG. 5 passes when the inner plug 40 and the cap 50 are assembled, and when the inner plug 40 and the cap 50 are assembled, the inner plug 40 is assembled.
  • the lid portion 421 is in the receiving portion 52 of the cap 50 and on the upper surface side of the cap 50 with respect to the protruding portion 53. Therefore, when the cap 50 is opened for the first time, the torque peak P shown in FIG. 5 does not appear, and the force (torque) for turning the cap 50 increases when the cap 50 pushes the lid 421. For this reason, a consumer who is opening the inner plug 40 and removing the cap 50 will not be mistaken for the inner plug 40 being opened. Realize.
  • cap assembly according to a second embodiment of the present invention will be described. Since the cap assembly of the second embodiment is easy to understand when compared with the above-described comparative example, the elements corresponding to the respective elements of the cap assembly 1A of the comparative example have a comparative example even if there are some differences in shape and the like.
  • the same reference numerals as those used in the drawings (FIGS. 1 to 4) of the cap assembly 1A are shown, and only the differences will be described.
  • FIG. 19 is a longitudinal sectional view of a cap assembly according to a second embodiment of the present invention.
  • the cap 20 receives the lid 121 in the receiving portion 22, the projection 23 is positioned below the lid 121, and the lid 121 is located inside the receiving portion 22.
  • the inner plug 10 is combined with the inner surface of the shell portion 21 in a state of being spaced from the inner surface of the shell portion 21.
  • the cap assembly 1C of the second embodiment in order to assemble the inner stopper 10 and the cap 20, as in the comparative example, after filling the bottle 30 with the contents and plugging the inner stopper 10, the cap 20 is removed. The procedure is to install.
  • an actual bottle 30 is used instead of the jig 70 shown in FIGS. 10 to 13, and the assembly method described with reference to FIGS. That is, the lid 121 is moved to the upper surface side of the shell 21 over the projection 23 in the receiving portion 22, and then the cap 20 is rotated in the reverse direction so that the lid 121 is immediately placed on the projection 23. An assembling method of positioning on the top is adopted.
  • FIG. 20 and FIG. 21 are explanatory diagrams of scenes where the cap is opened for the first time in the cap assembly 1C of the second embodiment.
  • the consumer turns the cap 20 in the closing direction. Then, as shown in FIG. 20, the cap 20 pushes down the lid portion 12 of the inner plug 10, thereby breaking the joint portion 121 b. Thereafter, when the cap 20 is rotated in the opening direction, the cap 20 is removed while the lid portion 121 of the inner plug 10 is held in the receiving portion 22 of the cap 20 as shown in FIG. At that time, the mouth of the inner plug 10 is already open.
  • the torque peak P shown in FIG. 5 In a state in which the inner plug 10 and the cap 20 are assembled, the lid portion 121 of the inner plug 10 is in the receiving portion 22 of the cap 20 and on the upper surface side of the cap 20 with respect to the protruding portion 23. Therefore, when the cap 20 is opened for the first time, the torque peak P shown in FIG. 5 does not appear, and the force (torque) for turning the cap 20 increases when the cap 20 presses the lid 121. For this reason, there is no possibility that the consumer who opens the inner plug 10 and removes the cap 20 will misunderstand that the inner plug 10 is opened. Realize.
