Detailed Description
The utility model is further illustrated by the following figures and examples.
Embodiment one:
as shown in fig. 1-9. The separation preventing structure for the inner and outer upper covers of the combined bottle cap comprises an outer upper cover 1, an outer upper cover top piece 13, an inner upper cover 2, a bottle mouth 3 and a lower cover 4.
The mouth 3 is fixedly connected with the lower cover 4 (welding or fastening, which is a common fixing connection in the art, for simplicity of description, only welding is used as an example in this embodiment).
The inner side of the lower cover 4 is provided with a back-off 41 which points obliquely upwards (which is matched with a locking collar 51 of the bottle neck 5 to prevent the lower cover 4 from being pulled up), and a lower cover anti-rotating rib 42 (which is matched with an anti-rotating rib 52 of the bottle neck 5 to prevent the lower cover 4 from rotating).
The outer side of the bottle mouth 4 is provided with bottle mouth threads 41.
The inner side of the outer upper cover 1 is provided with a blocking piece 11, and the blocking piece 11 is in a circular ring shape. The blocking piece 11 and the outer upper cover 1 are fixedly connected by one-time injection molding.
The outer upper cover 1 is covered outside the bottle mouth 4 from top to bottom.
The inner side of the inner upper cover 2 is provided with an inner upper cover thread 22 matched with the bottle mouth thread 41.
The inner cap 2 is introduced from the upper end into the outer cap 1 so that it is screwed outside the mouthpiece thread 41 and above the stop 11.
The inner diameter of the blocking member 11 is smaller than the maximum outer diameter of the inner upper cover 2, so that the inner upper cover 2 cannot pass through the blocking member 11 from top to bottom.
The outer upper cover top 13 extends downwardly a sleeve 14.
The sleeve 14 is a hollow cylinder, and the inner wall of the sleeve is provided with a sleeve anti-rotation rib 15 corresponding to the inner upper cover anti-rotation rib 21.
After the bottle mouth 3 is screwed on the inner upper cover 2, the sleeve 14 is pressed on the inner upper cover 2, so that the sleeve 14 covers the outer side of the inner upper cover anti-rotating rib 21, and the outer upper cover top piece 13 is fixedly connected with the outer upper cover 1. The connection mode includes but is not limited to welding and buckling. At this time, the inner upper cover 2 is sealed inside the outer upper cover 1.
After the bottle cap is assembled, the outer upper cover 1, the outer upper cover top piece 13 and the inner upper cover 2 are connected into a whole. The outer upper cover 1 is rotated, the inner upper cover anti-rotation rib 21 is driven to rotate through the sleeve anti-rotation rib 15, and the bottle cap can be unscrewed.
When the bottle cap is fitted with the bottle neck 5, since the inner diameter of the stopper 11 in the outer cap 1 is smaller than the maximum outer diameter of the inner cap 2, the inner cap 2 cannot be pulled out from the inner cap 1, i.e., the outer cap 1 cannot be separated from the inner cap 2, in the case of forcibly pulling the outer cap 1.
The shape of the hole of the blocking member 11 is a most commonly used shape, but not exclusively, but may be a polygon, and if the hole is a polygon, the inner diameter of the blocking member 11 refers to the diameter of the inscribed circle of the polygon.
In order to make the bottle cap have anti-counterfeiting function, an anti-counterfeiting whisker 43 can be arranged at the upper part of the lower cover 4, a corresponding notch 12 is arranged at the lower part of the upper cover 1, and when the bottle mouth 3 is arranged on the outer upper cover 1, the notch 12 is required to be aligned with the anti-counterfeiting whisker 43, so that the anti-counterfeiting whisker 43 is arranged in the notch 12. When the outer cap 1 is rotated to open the bottle cap, the anti-counterfeit whisker 43 is squeezed and broken, leaving an opening trace.
Embodiment two:
as shown in fig. 2, 5, and 7-13. A flange 23 can be arranged below the anti-rotation rib 21 of the inner upper cover on the outer side of the inner upper cover 2, a blocking piece 11 is arranged at the corresponding position of the outer upper cover below the flange, the blocking piece 11 is supported at the bottom of the flange 23, and the inner diameter of the blocking piece is smaller than the outer diameter of the flange 23. The blocking piece 11 and the outer upper cover 1 are fixedly connected through integral injection molding. When the outer cap 1 is pulled up after the cap is mounted, the flange 23 and the stopper 11 block each other, and the inner cap 2 cannot be pulled out from the outer cap 1 as well.
In this embodiment, except for the shape of the inner upper cover 2 and the shape and position of the blocking member 11, which are different from those of the first embodiment, other components and cooperation principles are the same as those of the first embodiment, and will not be described again.
Embodiment III:
as shown in fig. 14 and 15. The engagement of the sleeve 14 of the cover top with the rotatable member 24 of the upper portion of the inner cover can be accomplished in a number of ways, only one of which is provided by the engagement of the anti-rotation ribs in the first embodiment. The same effect can be achieved by providing the rotor 24 as a polygonal column and by having the shape of the inner cavity of the sleeve 14 of the cover top sheet correspond to the rotor 24.
In addition, it is obvious equivalent to interchange the positions of the sleeve and the rotating member, i.e. to arrange the rotating member below the cover top sheet and the sleeve above the inner upper cover.
The above description is only of the preferred embodiments of the present utility model, and is not intended to limit the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
