[0043] The bottle mouth clamp ring 4 is clamped in the annular gap between the annular protrusion 17 and the bottle body 7. The lower end of the outer side of the bottle mouth 14 is provided with an annular protrusion 17. The outer side of the annular protrusion 17 is clamped with an anti-theft clamp 19. The upper end surface of the anti-theft clamp 19 is connected to the lower end surface of the bottle cap 2 through a plastic strip. It is similar to the disposable breakable anti-theft ring at the bottle mouth of Nongfu Spring.

[0044] The outer circumferential surface of the bottle mouth 14 is connected to the bottle cap 2 through a thread. The outer circumferential surface of the bottle cap 2 is provided with two locking pin running grooves 21 upright at the bottom of the bottle body 7. The rotating locking pin 9 slidably connected to the surface of each lifting ear 8 can be slidably inserted into the corresponding locking pin running groove 21, which is convenient for the user to press the rotating locking pin 9 toward the middle of the bottle cap 2 and insert the locking pin roller 91 at the top of the rotating locking pin 9 into the groove of the locking pin running groove 21; it is convenient to hold the handle 1, and then slowly drag the handle 1 and rotate it along the bottle mouth 14. During the rotation of the handle 1, the bottle cap 2 is driven to rotate synchronously through the rotating locking pin 9.

[0045] Specifically, in the present embodiment, when the device is used for storing and transporting oil, the bottle mouth is tightly sealed and oil leakage will not occur, and the outer surface of the cylinder is provided with a pressure-resistant layer, which is convenient for stacking. At the same time, when opening the bottle cap, the user can use the handle as a lever to easily open the bottle cap 2; the bottle mouth clamp 4 is installed on the bottle mouth by press-fitting, and the provision of the handle 8 facilitates the rotation adjustment of the handle, and the bottle body 7 can be easily lifted by the handle.

[0046] A through circular hole is provided on the surface of the lifting ear 8, and a through center hole is provided on the surface of the lifting ear hook 15. The circular hole on the surface of the lifting ear 8 is coaxially connected with the center hole on the surface of the lifting ear hook 15.
