Description
Technical Field
The utility model belongs to the technical field of bottle caps, and particularly relates to a bottle cap capable of preventing an outer upper cap from being pulled out.
Background
The common multi-piece combined bottle cap in the market generally comprises an outer upper cover, an inner upper cover, a lower cover and a bottle mouth. The bottle mouth is fixedly connected with the lower cover; the outer side of the bottle mouth is provided with bottle mouth threads; an inner upper cover thread is arranged on the inner side of the inner upper cover and is matched with the bottle neck thread to be screwed on the outer side of the bottle neck, and an anti-rotation rib is arranged on the outer side of the inner upper cover; the inner side of the outer upper cover is provided with an anti-rotation rib corresponding to the outer side of the inner upper cover; the outer upper cover is tightly matched with the inner upper cover; the lower cover is fixedly connected to the bottleneck.
The bottle cap has the defect that when the bottle cap is integrally pressed on the bottle neck, the outer upper cap is pulled up by force, so that the outer upper cap is separated from the inner upper cap, and when the outer upper cap is held by a user with larger size errors (the fit of the inner upper cap and the outer upper cap is not too tight), the bottle and the rest part of the bottle cap slide from the outer upper cap.
Disclosure of Invention
In view of the above-mentioned shortcomings of the prior art, an object of the present utility model is to provide a bottle cap with firmly combined inner and outer caps, which can prevent the outer cap from being pulled out.
The technical scheme of the utility model is as follows:
a bottle cap for preventing an outer upper cover from being pulled out comprises an outer upper cover, an outer upper cover top sheet, an inner upper cover, a lower cover, a bottle mouth and a nut; the bottle mouth is fixedly connected with the lower cover; the outer side of the bottle mouth is provided with bottle mouth threads; an inner upper cover internal thread is arranged on the inner side of the inner upper cover and is matched with the bottle neck thread to enable the inner upper cover to be screwed on the outer side of the bottle neck, an inner upper cover anti-rotation rib is arranged on the lower portion of the outer side of the inner upper cover, and an inner upper cover external thread is arranged on the upper portion of the inner upper cover; the outer upper cover is fixedly connected to the outer side of the inner upper cover, an outer upper cover anti-rotating rib corresponding to the inner upper cover anti-rotating rib is arranged on the inner side of the outer upper cover, a nut supporting table is further arranged on the inner side of the outer upper cover, and a hole is formed in the middle of the nut supporting table; the nut supporting platform is positioned at the outer side of the inner upper cover; the external threads of the inner upper cover penetrate through the holes from bottom to top and protrude out of the nut supporting table; the inner side of the nut is provided with a nut thread corresponding to the external thread of the inner upper cover, and the nut is screwed on the outer side of the external thread of the inner upper cover; the aperture of the nut supporting table is smaller than the outer diameter of the nut; the outer upper cover top piece is fixedly connected with the outer upper cover.
Wherein, the inner side of the lower cover is provided with an inverted buckle and a lower cover anti-rotating rib, and the inverted buckle points to the obliquely upper side.
Wherein, the upper part of the lower cover is provided with an anti-counterfeiting whisker.
Wherein, the lower part of the outer upper cover is provided with a notch corresponding to the anti-counterfeiting whisker.
The beneficial effects are that:
when the inner upper cover is screwed on the bottle mouth, the inner upper cover is tightened on the outer upper cover through the nut, the top piece of the outer upper cover is fixedly connected with the outer upper cover, the nut is sealed in the outer upper cover, and a user cannot touch the bottle mouth. Compared with the tight fit of the background art, the screw thread fit between the nut and the inner upper cover can not separate the outer upper cover from the inner upper cover in a drawing mode, so that the outer upper cover is prevented from being pulled out.

Detailed Description
The utility model is described in further detail below with reference to the accompanying drawings.
Examples:
as shown in fig. 1-10. The bottle cap for preventing the outer upper cap from being pulled out comprises an outer upper cap 1, an outer upper cap top piece 14, an inner upper cap 2, a nut 3, a bottle mouth 4 and a lower cap 5.
The mouth 4 is fixedly connected with the lower cover 5 (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 5 is provided with a back-off 51 (which is matched with a locking collar 61 of the bottleneck 6 to prevent the lower cover 5 from being pulled up) and a lower cover anti-rotating rib 52 (which is matched with an anti-rotating rib 62 of the bottleneck 6 to prevent the lower cover 5 from rotating).
The outer side of the bottle mouth 4 is provided with bottle mouth threads 41.
The inner side of the inner upper cover 2 is provided with an inner upper cover internal thread 22 corresponding to the bottle neck thread 41, the outer side of the inner upper cover 2 is provided with an inner upper cover external thread 23, and an inner upper cover anti-rotation rib 21 is arranged below the inner upper cover external thread 23.
The inner upper cover 2 is rotatably connected to the outer side of the bottle mouth 4.
The outer upper cover 1 is fixedly connected to the outer side of the inner upper cover 2.
The inner side of the outer upper cover 1 is provided with an outer upper cover anti-rotation rib 11 corresponding to the inner upper cover anti-rotation rib 21, and the inner side of the outer upper cover 1 is also provided with a nut supporting table 12.
The middle of the nut support table 12 is provided with a hole.
The nut support table 12 is located outside the inner upper cover 2.
The inner upper cover external thread 23 of the inner upper cover 2 passes through the hole from bottom to top and protrudes out of the nut supporting platform 12.
The inner side of the nut 3 is provided with a nut thread 31 corresponding to the inner upper cover external thread 23, and the nut 3 is rotationally connected to the outer side of the inner upper cover external thread 23.
The aperture of the nut support table 12 is smaller than the outer diameter of the nut 3 so that the nut 3 cannot pass through the nut support table 12.
After the nut thread 31 is screwed with the external thread 23 of the inner upper cover, the inner upper cover 2 is fixed on the outer upper cover 1 and cannot be pulled out, and the outer upper cover anti-rotation rib 11 and the inner upper cover anti-rotation rib 21 are matched to prevent relative rotation between the two.
After the outer upper cover top sheet 14 is fixedly connected with the outer upper cover 1 (including but not limited to welding or fastening, etc.), the nut 3 is enclosed in the outer upper cover 1, so that the nut cannot be accessed by a user. Because the nut 3 is matched with the inner upper cover 2 in a screwing mode, after the bottle cap presses the bottle neck 6, a user cannot separate the outer upper cover 1 from the inner upper cover 2 in a mode of strongly pulling out the outer upper cover 1.
In order to make the bottle cap have anti-counterfeiting function, an anti-counterfeiting whisker 53 can be arranged at the upper part of the lower cover 5, a corresponding notch 13 is arranged at the lower part of the upper cover, and when the outer upper cover 1 presses the inner upper cover 2, the notch 13 is required to be aligned with the anti-counterfeiting whisker 53 to be pressed down, so that the anti-counterfeiting whisker 53 is arranged in the notch 13. When the outer upper cover 1 is rotated to open the bottle cap, the anti-counterfeiting whisker 53 is squeezed and broken, and an opening trace is left.
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.
