Description of the Related Art A double cap is known which prevents a baby from inadvertently opening a lid of a container containing a liquid such as a drug which causes harm when touched or swallowed by a baby. A double safety cap described in Japanese Utility Model Application No. 60-66787 (Japanese Utility Model Application Laid-Open No. 61-183833) is one of them. The double safety cap disclosed in Japanese Utility Model Application No. 60-66787 has an inner lid that is screwed into the mouth of the container to close the mouth, and an elastically deformable outer lid that covers the inner lid.
The inner surface of the top plate of the outer lid and the outer surface of the inner lid top plate facing the outer cover are provided with ratchet teeth to be disengaged, respectively. A ridge is provided along each. When the outer lid is turned in a direction to close the mouth of the container with the inner lid, the ratchet teeth engage with each other to close the mouth of the container with the inner lid. Conversely, when the outer lid is turned in a direction to open the mouth of the container, the outer lid merely idles with respect to the inner lid due to the separating operation of the ratchet teeth.
When opening the mouth of the container, grasp the outer lid, push the peripheral wall of the outer lid against the inner lid with a finger to engage the ridges and integrate both lids, and open the outer lid in this state Rotate in the direction. The ridge is engraved on the entire peripheral surface of the inner wall of the outer lid and the outer surface of the peripheral wall of the inner lid.

る。The above double safety cap rotates the outer lid when the inner lid closes the container when the ratchet teeth which are disengaged from each other maintain a normal engagement. However, the ratchet teeth of the outer lid are provided on the inner surface of the outer lid top plate and the outer surface of the inner lid top plate facing thereto, so that the ratchet teeth of the outer lid are securely engaged with the ratchet teeth of the inner lid. In order to match, the separation distance between the inner surface of the outer lid top plate and the outer surface of the inner lid top plate needs to be always kept accurately. If this separation distance goes wrong, the engagement between the ratchet teeth becomes uncertain,
Simply turning the outer lid makes the outer lid run idle and cannot be closed.To close the lid, the outer lid must be rotated with the top of the outer lid pressed against the inner lid. However, there is a problem that an operation different from the original closing operation must be performed. Further, in the case of a double cap having a relatively small diameter, in the form in which the ratchet teeth are provided on the top plate on the lid, the length from the center of rotation of the lid to the ratchet teeth is shortened. There is a problem that the action to be transmitted to the inner lid is mechanically unreasonable.

を大きくすることなく高さを低く作ることができる。According to the present invention, the engagement between the engaging and disengaging projections provided between the outer lid and the inner lid and the engaged and disengaging projections is constant without giving any deformation to the outer lid. When the container is closed, not only is it necessary to grasp the outer lid with a finger and turn it, but also the engagement and disengagement projections and the engagement and disengagement projections are closed and closed. Are provided between the peripheral surfaces of the two, so that the engagement between them is always maintained in a good state. In addition, since the engagement / disengagement projection and the engagement / disengagement projection are provided between the outer lid and the inner cover, and the distance between the rotation center of the lid and the engagement / disengagement projection can be set to a maximum, even a lid having a relatively small diameter can be used. In terms of mechanics, the torque of the outer lid can be efficiently transmitted to the inner lid. Furthermore, the engagement relationship between the engagement / disengagement projection and the engaged / unengageable projection is always set to a state in which engagement is possible without giving any deformation to the outer lid. In, it is only necessary to push the pushing portion with a finger and turn the outer lid a little, and then remove the force from the pushing portion and turn the outer lid.
Such an operation can be achieved by partially providing the pushing portion which cooperates with the engaged / disengaged projection which can always be engaged with the engaging / disengaging projection, so that the effect of the pushing portion in the present invention is achieved. Is big. Furthermore, the height can be made lower without increasing the diameter dimension as compared with the conventional double cap in which ratchet teeth are provided on the top plate of each of the inner and outer lids.
