In another embodiment of the present invention, as shown in fig. 24 to 27, the main differences between this embodiment and the above embodiment are as follows: the cover body 20 of the embodiment cancels the extrusion hole 23, the fastening ring cancels the buckling part 32, the acting surface is directly arranged at one side of the notch 31-b far away from the case body 41, the key 40 extends towards the central line direction to form a convex block which can be directly buckled with the groove 12-a, the sealing part 70 is cancelled, the inner container 80 is added, and the opening of the inner container 80 is provided with a covered edge 81 which is detachably connected with the connecting part 12 through a buckling mechanism 82.

Specifically, the structure of the present embodiment includes: bottle 10, lid 20, retainer ring 30 and button 40. The bottle body 10 is a hollow structure and comprises a bottle body 11 and a connecting part 12 which are communicated with each other, the connecting part 12 is positioned at the opening side of the bottle body 10, and a groove 12-a along the cross section direction is arranged at the outer side of the connecting part 12. The cover 20 has a cover slot 21 that can be fastened to the connecting portion 12, and a key hole 22 that is conducted with the cover slot 21 is formed on the side wall of the cover 20. The fixing ring 30 is detachably installed in the cover groove 21, a radial gap is formed between the fixing ring and the cover groove 21, notches 31-b are formed in two sides of the fixing ring 30, and the notches 31-b are located on two sides of the center line of the key hole 22. Since the key hole 22 is formed in the side surface of the lid body 20, the center line direction of the key hole 22 is perpendicular to the axial direction of the lid groove 21. In addition, in the drawings of the present embodiment, the bottle body 10, the cover 20 and the fixing ring 30 are all located on the same center line, and the cross-sectional direction is circular, and other shapes can be designed in practical applications.

Further, the key 40 includes a key main body 41 and an abutting portion 42 connected to each other, and the key main body 41 is located in the middle of the abutting portion 42 and is matched with the key hole 22. The abutting part 42 is an open ring structure, two ends of the abutting part extend along the inner wall of the cover groove 21 towards the direction far away from the key hole 22, the tail end of the abutting part abuts against the action surface 32-b of the notch 31-b, and two ends of the abutting part 42 are respectively provided with a boss facing the groove 12-a, and the bosses correspond to the notches 31-b.

In the actual use process, two states exist, in the natural state, a gap is reserved between the key body 41 and the fixing ring 30, the boss is matched with the groove 12-a through the notch 31-b, and a first radial distance is reserved between the two bosses. In a pressed state, the key body 41 moves towards the fixing ring 30 under the action of external force, two sides of the abutting part 42 expand outwards, the bosses exit from the grooves 12-a, a second radial distance exists between the two bosses, and the second radial distance is larger than the first radial distance. The first radial distance and the second radial distance are not explicitly identified in the drawings of this embodiment, because the abutting portion 42 is an open ring structure, when the key main body 41 is pressed, the end of the abutting portion 42 is simultaneously subjected to the reaction force of the notch 31-b of the fixing ring 30, at this time, the key main body 41 moves inward along the center line direction of the key hole 22, the size of the abutting portion 42 along the center line direction of the key hole 22 decreases, the distance between the two bosses of the abutting portion 42 increases, that is, the second radial distance is greater than the first radial distance. Thereby enabling the boss of the abutting part 42 to exit the groove 12-a and realizing the separation of the cover body 20 and the bottle body 10.

The abutting portion 42 of the present embodiment has a similar open ring structure as the abutting portion 42 of the previous embodiment, and the protruding portion of the abutting portion 42 is directly engaged with the groove 12-a of the present embodiment, while the engaging portion 32 of the fixing ring 30 is engaged with the groove 12-a of the previous embodiment. However, in all the embodiments described above, the abutting portion 42 and the notch 31-b or the engaging portion 32 are pressed against each other to deform the abutting portion 42 or the engaging portion 32, thereby achieving the detachment of the cap 20 and the bottle 10 from each other.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
