The status is released. Therefore, it is possible to prevent the lock state of the lid from being released when the pressing operation of the conventional operation button is inadvertent (so-called one operation).

Further, in the bottle cap structure 3 of the present embodiment, since it is not necessary to provide a safety stopper or the like as in the related art, the number of parts does not increase, and the case where the lid body 9 is inadvertently opened can be prevented from being inadvertently operated.

Further, in the cap structure 3 of the present embodiment, when the operation knob 27 is slid, the operation can be performed under the continuous operation of pressing the operation knob 27. Therefore, the cap of the present invention can be operated without first removing the cap from the prior art, operating the operating button, or operating the operating button 27 after releasing a safety stop. Structure 3 further enhances usability.

Further, in the cap structure 3 of the present embodiment, since the hook portion 35 protrudes from the outer side (front side) between the slits 9d only when the lock state of the lid body 9 is released, the lock cover body 9 is locked. In the state in which the hook portion 35 is located inside the slit 9d, it is difficult to release the locking state at the hook portion 35. Apply force in the direction. Further, the hook portion 35 is hard to be broken.

As described above, in the beverage container 1 having the cap structure 3 of the present embodiment, it is possible to prevent the lid 9 from being opened due to careless handling, and further improvement in usability can be achieved.

The present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit and scope of the invention. For example, the beverage container 1 is not limited to have the above-described external shape, and can be appropriately changed in accordance with the size, function, design, and the like.

Moreover, the present invention is applicable to the beverage container 1 having the temperature and cold retention function by the container body 2 having the above-described vacuum heat insulating structure. However, the present invention is not limited to the container body 2 having the vacuum heat insulating structure. That is, the present invention can be widely applied to a beverage container in which the cap structure is detachably attached to the neck of the container body.
