A portion 241 is provided.
More specifically, by deforming the elastically deformed portion 34 to the outside of the outer peripheral wall 33 of the lid, the elastically deformed portion upper surface 342 of the elastically deformed portion 34 engages with the undercut portion lower surface 242 of the undercut portion 241 and is elastically deformed portion. By the action of 34 pressing the undercut portion 241 inward from the outside, the elastically deformed portion 34 and the engaging portion 24 are engaged, and the lid 3 is not opened (the lid 3 is closed). It is in the state of).

Next, with reference to FIG. 4B, a procedure for releasing the first locked state and opening the lid 3 will be described. Here, in FIG. 4B, i indicates the first operation, and ii indicates the second operation.

When the knob portion 25 is first pushed in the direction of the arrow of i (first operation), the engaging portion 24 is interlocked with the knob portion 25, so that the engaging portion 24 also moves in the direction of the arrow of i, and the elastic deformation portion 34 And the engaging portion 24 (undercut portion 241) are separated from each other, and the elastic deforming portion 34 and the engaging portion 24 are disengaged. That is, the first locked state is released. Next, the lid 3 can be opened by holding the elastically deformed portion 34 and lifting it in the direction of the arrow of ii (second operation).
The engaging portion 24 may be directly pushed in the direction of the arrow i to disengage the elastically deformed portion 34 and the engaging portion 24. Further, when the lid 3 is lifted in the direction of the arrow of ii after the elastically deformed portion 34 and the engaging portion 24 are disengaged, the lid 3 may be lifted while holding the vicinity of the elastically deformed portion 34.

In order to return to the first locked state again, the elastically deformed portion 34 and the engaging portion 24 may be engaged when the lid body 3 is closed. That is, the lid 3 may be pushed in the direction of the bottom surface portion 11 (FIG. 3 or the like) until the upper surface surface 342 of the elastically deformed portion 34 of the elastically deformed portion 34 and the lower surface 242 of the undercut portion of the undercut portion 241 are engaged.

In this way, in the first locked state, the elastically deformed portion 34 and the engaging portion 24 can be easily disengaged by simply operating the knob portion 25, so that the characteristics of the contents contained in the container can be understood. For adults who are doing this, it is easy to open the lid when opening the container.

Next, the second locked state will be described with reference to FIGS. 5 and 6. The parts that overlap with FIG. 4 will be omitted in detail and will be described mainly on the different parts.

A cross-sectional view at the time of transition from the first locked state to the second locked state is described.

The second locked state is a state for enabling the so-called child resistance function, which can prevent a child or the like from unnecessarily removing the lid of the container.
As shown in FIGS. 5A and 5B, in the second locked state, the positional relationship between the elastically deformed portion 34 and the engaging portion 24 is different from that in the first locked state.

In the second locked state, the elastically deformed portion 34 is inverted inward of the outer peripheral wall 33 of the lid, so that the engaging portion 24 (inner wall 243 of the engaging portion) is engaged from the outside of the elastically deformed portion 34 and the lid. The body 3 cannot be opened (the lid 3 is closed). In other words, the elastically deformed portion 34 is suppressed inward by the engaging portion 24 and deformed so as to be recessed, and is engaged with the engaging portion 24. Therefore, the lid body 3 is in a state where it cannot be easily removed. As a result, the structure is such that the child resistance function works effectively.
Therefore, even if a child or the like tries to lift and open the lid 3 in the direction of the arrow shown in FIG. 5 (B), the lid 3 cannot be easily removed and therefore cannot be opened.

Finally, a procedure for shifting from the first locked state to the second locked state and a procedure for releasing the second locked state and opening the lid 3 will be described.
6 (A) to 6 (C) are cross-sectional views at the time of transition from the first locked state to the second locked state.
FIG. 6A shows a cross-sectional view of the first locked state portion. If it is not desired for a child or the like to open the lid 3, it is necessary to enable the child resistance function in the second locked state. In that case, it is necessary to shift from the first locked state to the second locked state.

FIG. 6B shows a procedure for transitioning from the first locked state to the second locked state (FIG. 6C). In FIG. 6B, i indicates the first operation and ii indicates the second operation.

From the state of FIG. 6 (A), as shown in FIG. 6 (B), when the knob portion 25 is lifted in the direction of the arrow of i (first operation), it comes into contact with the inner peripheral surface of the elastically deformed portion 34. The engagement of the engaging portion 24 with the undercut portion 241 is released. After that, when the elastically deformed portion 34 is pushed in the direction of the arrow of ii (second operation), it is inverted inward and stored in the engaging portion 24. The elastically deformed portion 34 housed in the engaging portion 24 comes into contact with a part of the inner wall 243 forming the inner surface of the engaging portion 24, that is, the upper end surface portion of the inner wall 243 of the engaging portion 24. The second locked state is completed by engaging with and engaging with (FIG. 6 (C)).

To release the second locked state, the grip portion 25 may be lifted in the direction of the arrow i from the state shown in FIG. 6C, and then the elastically deformed portion 34 may be pulled up. Then, the lid 3 can be opened (Fig. 3).

In this embodiment, the knob portion 25, the engaging portion 24, and the elastically deformed portion 34 are provided on the front side (FIG. 1 (B)) of the container A with the closing tool, but even if they are formed on the side surface side. good. It is also possible to provide it at a plurality of locations.
