  According to such a configuration, when the discharge device 1 is mounted on the container main body 6, the second engagement portion 32 is moved to the second axial position by fitting the jig 37 to the covering cap 3, and in this state By grasping and twisting the jig 37 and the covering cap 3, the torque is transmitted to the mounting cap 2 via the first engaging portion 29 and the second engaging portion 32 of the annular body 4, and the inner cylinder 12 of the mounting cap 2 is transmitted. Can be attached to the mouth portion 7 of the container body 6.

  In the state where the discharge device 1 is mounted on the container body 6, the operation portion 35 of the annular body 4 is disposed in a narrow gap between the lower end of the outer cylinder 21 and the step portion 36 of the container body 6. The operation part 35 cannot be pushed up with a finger, and the state in which the second engagement part 32 is in the first axial position is maintained. Therefore, even if a person who does not have the jig 37 grasps the cover cap 3 and twists it, the mounting cap 2 cannot be rotated only by the rotation of the cover cap 3, and the discharge device 1 cannot be rotated by the container body 6. You cannot leave.

  Further, when a person having the jig 37 causes the discharge device 1 to be detached from the container body 6, the second engagement portion 32 is moved to the second axial position by fitting the jig 37 to the covering cap 3. In this state, the jig 37 and the covering cap 3 are grasped and twisted in the opposite direction at the time of mounting, and the torque is applied to the mounting cap 2 via the first engaging portion 29 and the second engaging portion 32 of the annular body 4. In other words, the inner cylinder 12 of the mounting cap 2 can be detached from the mouth portion 7 of the container body 6.

  Thus, in this embodiment, since the 1st engaging part 29 is comprised by the convex part 30 extended in an up-down direction, the structure is simplified. Moreover, since the 2nd engaging part 32 is comprised by the convex part 33 extended in an up-down direction, the structure is simplified. Moreover, since the annular body 4 has the operation part 35, the structure of the contact part 38 of the jig | tool 37 is simplified. Further, since the discharge device 1 includes the urging member 44, the second engagement portion 32 can be maintained at the first axial position even when the discharge device 1 mounted on the container body 6 is tilted. Therefore, it is possible to more reliably prevent a person who does not have the jig 37 from detaching the discharge device 1 from the container body 6. Further, since the urging body 44 is configured by the leaf spring 45 of the annular body 4, the configuration is simplified.

  Next, the cap 51 according to an embodiment of the present invention will be described in detail with reference to FIG. In FIG. 8, the same components as those shown in FIGS. 1 to 7 are denoted by the same reference numerals. As shown in FIG. 8, the cap 51 according to the embodiment includes an inner cap 52, an outer cap 53, and an annular body 4, and is configured to be detachable from the mouth portion 7 of the container body 6. In the present embodiment, the cap 51 further includes a jig 37 that is used for the attachment / detachment operation of the cap 51 with respect to the mouth portion 7. In the present embodiment, the inner cap 52 and the outer cap 53 are each a molded product (injection molded product) made of a synthetic resin material. However, the inner cap 52 and the outer cap 53 are not limited to such molded products. In the present embodiment, the content of the container body 6 is a solid such as a drug. However, the content is not particularly limited, and may be a liquid such as a chemical solution.

  The inner cap 52 integrally has an inner cylinder 12 in which an internal thread 11 is formed on the inner peripheral surface as an engaging portion that can be attached to and detached from the mouth portion 7 of the container body 6. The engaging portion may be a convex portion or a concave portion that can be attached to and detached from the mouth portion 7 by snap-fit fitting instead of the female screw 11. A top wall 54 extending radially inward is integrally connected to the upper end of the inner cylinder 12. In the present embodiment, the top wall 54 covers the open end of the mouth portion 7 of the container body 6. However, the top wall 54 may have an opening. In addition, for example, a top plate (not shown) that covers the open end of the mouth portion 7 of the container body 6 may be formed separately from the inner cap 52 and assembled to the inner cap 52.

  The outer cap 53 integrally has the outer cylinder 21 disposed on the radially outer side of the inner cylinder 12. The outer cap 53 is rotatably held by the inner cap 52. A ceiling wall 55 extending inward in the radial direction is integrally connected to the upper end of the outer cylinder 21. The ceiling wall 55 is disposed along the top surface of the top wall 54 of the inner cap 52, and a slide for reducing sliding resistance between the ceiling wall 55 and the top wall 54 is provided on the bottom surface of the ceiling wall 55. A moving convex portion 23 is formed.

  According to such a configuration, when the cap 51 is attached to the container body 6, the second engagement portion 32 is moved to the second axial position by fitting the jig 37 to the outer cap 53, and in this state, the cap 51 is cured. By grasping and twisting the tool 37 and the outer cap 53, the torque is transmitted to the inner cap 52 via the first engaging portion 29 and the second engaging portion 32 of the annular body 4, and the inner cylinder 12 of the outer cap 52 is transferred. It can be attached to the mouth 7 of the container body 6.

  In the state where the cap 51 is attached to the container body 6, the operation part 35 of the annular body 4 is arranged in a narrow gap between the lower end of the outer cylinder 21 and the step part 36 of the container body 6. Thus, the operation unit 35 cannot be pushed up, and the state where the second engagement unit 32 is in the first axial position is maintained. Therefore, even if a person who does not have the jig 37 grasps and twists the outer cap 53, the inner cap 52 cannot be rotated only by rotating the outer cap 53, and the cap 51 is removed from the container body 6. It cannot be removed.

  Further, when a person having the jig 37 removes the cap 51 from the container body 6, the second engagement portion 32 is moved to the second axial position by fitting the jig 37 to the outer cap 53. By gripping the jig 37 and the outer cap 53 and twisting in the opposite direction at the time of mounting, the torque is transmitted to the inner cap 52 via the first engaging portion 29 and the second engaging portion 32 of the annular body 4. The inner cylinder 12 of the inner cap 52 can be detached from the mouth portion 7 of the container body 6.

  Thus, in this embodiment, since the 1st engaging part 29 is comprised by the convex part 30 extended in an up-down direction, the structure is simplified. Moreover, since the 2nd engaging part 32 is comprised by the convex part 33 extended in an up-down direction, the structure is simplified. Moreover, since the annular body 4 has the operation part 35, the structure of the contact part 38 of the jig | tool 37 is simplified. In addition, since the cap 51 includes the biasing body 44, the second engagement portion 32 can be maintained at the first axial position even when the cap 51 attached to the container body 6 is tilted. Further, it is possible to more reliably prevent a person who does not have the jig 37 from detaching the cap 51 from the container body 6. Further, since the urging body 44 is configured by the leaf spring 45 of the annular body 4, the configuration is simplified.

  The above description is merely an example of an embodiment of the present invention, and it goes without saying that various modifications may be made without departing from the gist of the invention.
