The inner diameter of the first tubular portion 87 has a size corresponding to the outer diameter of the inner lid 31, and the inner lid 31 can be received. On the inner peripheral surface of the first tubular portion 87, a slightly raised vertical convex strip 91 extending in the vertical direction of the tubular portion 87 is provided corresponding to the vertical groove 39 of the inner lid 31. By fitting the vertical ridges 91 into the vertical grooves 39, the inner lid 31 received inside is the outer lid 5
It is stopped against 5. At a position near the second tubular portion 89 on the inner peripheral surface of the first tubular portion 87, a slightly raised ridge 93 extending in the circumferential direction is formed as a pull-out preventing locking portion. The height dimension from the inner side surface of the top wall 85 to the slip-out preventing locking portion 93 is determined corresponding to the height of the inner lid 31. Therefore, the pullout preventing locking portion 93 is locked to the lower end portion of the inner lid 31 received inside, and the inner lid 31 is prevented from being pulled out and is integrally held by the outer lid 55. In another embodiment, the inner surface of the top wall 85 of the outer lid 55 and the outer surface of the top wall 37 of the inner lid 31 may be bonded with an adhesive. Further, in the case of a container having a relatively large diameter, the inner lid 31 can be formed by combining the above-mentioned structure for retaining and preventing rotation and adhesion.

The tubular portion 89 of the fitting member 53 is fitted to the outside of the second tubular portion 69 of the mounting member 53, and at that time, the locked projection 97 rides over the locking projection 75 of the mounting member 53, and the outer lid 55. The attachment member 53 is hooked.

FIG. 5 is a sectional view of the inner lid 101 mounted inside the inner lid 31. The inner lid 101 includes a tubular portion 102 including a large diameter portion 103 and a small diameter portion 105, and a tubular portion 10.
It has a bottom wall 107 that closes the bottom of No. 2 and a flange 109 that extends radially outward at the upper end of the large diameter portion 103. A ridge 115 extending in the circumferential direction is formed on the inner peripheral surface of the large-diameter portion 103, and the ridge 115 is fitted into the circumferential groove 43 of the inner lid 31 to attach the inner lid 101 to the inner lid 31. . Tube 1
A moisture-proofing agent 120 or the like is appropriately stored in the inner cavity 117 of 02,
The tongue piece 45 of the inner lid 31 presses it down. Bottom wall 107
A through hole 111 is formed in the inner wall surface of the bottom wall 107.
A plurality of shallow grooves or depressions 113 having an appropriate planar shape are formed in a state of communicating with each other, and a large contact area of the moistureproof agent with air is secured.

FIG. 6 shows a state in which the lid 5 is attached to the container body 3 and the female screw 35 of the inner lid 31 is screwed into the male screw 11 of the container body 3 to completely close the container body 3. The cross-sectional view corresponds to FIG. In order to attach the lid body 5 to the container body 3 first, the inner lid 31 is fixed in the outer lid 55, and the outer lid 55 is placed on the attachment member 53.
That is, it is fitted into the neck portion 7 of the container body 3 in the closed position. In order to facilitate the fitting at this time, as shown in FIG. 6, the cylindrical portion of the attachment member 53 is provided with a slit 70 from the lower surface side to a predetermined position as shown in FIG. It has a heavy structure. Alternatively, the cylindrical portion of the attachment member 53 may be divided at one place in the circumferential direction. During the fitting work, the rotation prevention stopper 19 of the container body 3 and the rotation prevention locking portion 79 of the attachment member 53 are attached.
It is necessary to perform positioning by taking into consideration the positional relationship between and in the rotation direction. When the retaining contact portion 77 of the attachment member 53 gets over the flange portion 15 of the container body 3 and fits into the lid mounting portion 13, the lid body 5 is then rotated in the closing direction to close the female screw 35 of the inner lid 31. The male screw 11 of the container body 3 is screwed into the container body 3 to be tightened and sealed.

In this state, the lid mounting portion 13 of the container body 3 and the attachment member 53 fitted to the lid mounting portion 13 are unfolded to form the container body 3
The positional relationship among the collar portion 15, the rotation prevention stopper 19, the slide prevention stopper 23, the retaining contact portion 77 of the attachment member 53, the rotation prevention locking portion 79, and the slide prevention locking portion 81 is shown as a schematic diagram. What is shown is (a) of FIG. As is clear from the figure, the retaining contact portion 77 is not in contact with the collar portion 15, and the rotation prevention locking portion 77 is not the rotation prevention stopper 1.
9, the slide prevention locking portion 81 is not placed on the slide prevention stopper 23.

In this closed state, the inner lid 10
The flange 109 of No. 1 is compressed between the inner surface of the inner lid 31 and the end surface of the opening 9 of the container main body to enhance the airtightness of the container. Further, since the tongue piece 45 pushes the moisture-proofing agent 120 in the inner lid 101 downward and presses it against the bottom wall 107 of the inner lid 101, even if the container 1 is tilted, the medicine inside will pass through the through hole 11.
It is prevented from entering the inside of the inner lid 101 through 1.

When the lid body 5 is rotated in this state in the opening direction, the entire lid body 5 rises as shown in FIG.
The female screw 35 and the male screw 11 of the container body 3 are disengaged from each other. In addition, in the present embodiment, as described above, the screw is a four-threaded screw, and the screwing is disengaged by rotating about 90 degrees from the tightened state. It is in a state in which it is slightly further rotated in the same direction after it is disengaged.
This state corresponds to (b) in FIG. At this time, the lid attachment portion 13 of the container body 3 and the attachment member 53 of the outer lid 55 are unfolded, and the flange portion 15, the rotation prevention stopper 19, the slide prevention stopper 23 of the container body 3 and the attachment member 53 are prevented from coming off. Contact portion 77, rotation prevention locking portion 79, slide prevention locking portion 81
FIG. 8B is a schematic diagram showing the positional relationship between and. As is apparent from the figure, the rotation prevention locking portion 79 contacts the left end surface 21 of the rotation prevention stopper 19 to restrict further rotation in the opening direction, and the slide prevention locking portion 81 functions as the slide prevention stopper. The slide prevention stopper 23 supports the entire lid body 5 underneath. At this time, the retaining contact portion 77 and the collar portion 15
Although there is a slight gap between and, even if the lid body 5 is pulled upward in this state, the retaining contact portion 77 abuts on the flange portion 15 and is retained. Further, at this time, the retaining contact portion 7
The left end surface 78 of one 77b of 7 is the rotation preventing stopper 1
It is located in the immediate vicinity of the right side end face 20 of 9. This prevents the lid 5 from rotating carelessly in the closing direction. FIG. 9 is a partially enlarged cross-sectional end view taken along line 9-9 of FIG. As can be understood from FIGS. 8 and 9, when the lid body 5 moves from the state of FIG. 8A to the state of FIG. 8B, one of the retaining contact portions 77b is a rotation preventing member. It rides on the stopper 19 and moves to reach the state of (b). In order to facilitate this riding, the right end surface of the retaining contact portion 77b is an inclined surface 80. Even when the stopper is closed, the stopper contact portion 77b has the rotation prevention stopper 19b.
The left end surface of the retaining contact portion 77b is formed as an inclined surface 78 in order to make it easier to move to the state of (a). The right end surface of the rotation prevention stopper 19 is also an inclined surface 20. Both the surfaces 20 and 78 are inclined, but a certain amount of force is required for the slip-out preventing contact portion 77b to ride on the rotation preventing stopper 19. 5 is careless (b)
It is prevented from rotating from the state of (1) to the state of (a), that is, in the closing direction.

In the state shown in FIG. 7, the lid main body 30, that is, the outer lid 55 and the inner lid 31 are opened together by removing the locked projection 97 from the locking projection 75 of the attachment member 53. It can be opened to the position and opened as shown in FIG. At this time, since the spring member 63 has a snap action, the opening operation can be performed by one-touch operation, and the lid body 30
Is convenient because it acts to hold the open position. Reverse the above procedure to close the cap. If the slide prevention stopper 23 and the slide prevention locking portion 81 are not provided, when the lid main body 30 is opened to the open position, the attachment member 53, and thus the entire lid body 5 is lowered downward, and the lid is then closed. When returning the main body 30 to the closed position, the main body 30 buffers the tip of the neck portion 7 of the container main body 3 and cannot be closed as it is. Therefore, it is extremely effective to provide the slide prevention stopper 23 and the slide prevention locking portion 81.

In the embodiment described above, since only one anti-rotation stopper 19 of the container body 3 and one anti-rotation locking portion 79 of the attachment member 53 are provided, as described above. When attaching the lid body 5 to the container body 3, it is necessary to perform the operation in consideration of the positional relationship between the rotation prevention stopper 19 and the rotation prevention locking portion 79. Depending on the container, there is a case where a storage case for storing the instruction manual of the drug is attached to the outer side of the container, for example, the front side. In such a case, because of the relationship with this storage case, the front surface of the lid body 5 having a label or the like including the indication of the drug on the top surface is located at a specific position with respect to the container body 3. It is desirable that the above-mentioned embodiment be adopted, and it is recommended to adopt the configuration as in the above-described embodiment.

On the other hand, when such a storage case is attached to the bottom of the container body, the lid does not need to be attached so that its front surface is located at a specific position with respect to the container body, but rather in this case. In addition, the work of attaching the lid body to the container body becomes easier if it is not set at a specific position. FIG. 10 shows a container body 151 according to the second embodiment having such a configuration.

The container body 151 is provided with four rotation preventing stoppers 153 arranged at equal intervals in the circumferential direction and four slide preventing stoppers 155 similarly provided at equal intervals in the circumferential direction. There is. On the other hand, although not shown,
Correspondingly, the lid body is provided with four rotation prevention locking portions and slide prevention locking portions, which are described in the first embodiment, at equal intervals in the circumferential direction. The rotation prevention stopper 153 may have the same structure as that in the first embodiment, and the structure of the rotation prevention locking portion and the slide prevention locking portion of the lid body can be easily described from the description of the first embodiment. Since it can be understood, its explanation is omitted.

FIG. 11 is an enlarged front view showing details of the slide prevention stopper 155, and FIG. 12 is a sectional view. The slide prevention stopper 155 has one slide prevention locking portion 171A of the lid body when the lid body is in the opening position.
Is provided with a flat portion 157 to be placed thereon and an inclined portion 159 connected to the flat portion 157. The inclination of the inclined portion 159 is formed substantially corresponding to the lead of the screw of the container body 151, and when the lid is rotated, the slide prevention locking portion 171 of the lid moves substantially along this.

As shown clearly in FIG. 12, the flat portion 1
57 and a part of the inclined portion 159 connected to this,
In the lower part, there is a recess 161 that is recessed in the radial direction of the container body.
Are formed. And when the lid is in the closed position,
The slide prevention locking portion 171B adjacent to the slide prevention locking portion 171A is at least partially accommodated in the recess 161 as shown in FIG.
With this configuration, the rotation angle of the cover body of about 90 degrees is secured.

In the above description, four rotation preventing stoppers 153 of the container body 151 are provided, and four rotation preventing locking portions of the lid are provided correspondingly, but one of them is one. There is no problem in just doing it. Further, four slide preventing stoppers 155 of the container main body and corresponding slide preventing locking portions of the lid body are provided, but the number is not necessarily limited to this number.

Various modifications can be made to the above-described embodiment within the scope of the present invention.
