[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0023] Referring to Figures 1-7The application discloses an interference fit sealing bottle cap of an ink bottle, which comprises a bottle body 1, a detachable bottle mouth 2 arranged on the top of the bottle body 1, and a detachable bottle cap 3 arranged on the outer side of the bottle mouth 2, and a sealing ring column 13 arranged on the top of the bottle body 1. The bottle mouth 2 is internally provided with a sealing cavity 21, the sealing ring column 13 is arranged in the sealing cavity 21 to form a seal, and the sealing cavity 21 is internally provided with a sealing inclined surface 22 and a sealing convex ring 23 matched with the sealing ring column 13.

[0024] The top of the bottle body 1 is provided with a bottle mouth 11, and the outer side of the bottle mouth 11 is provided with an external thread 12. The inner wall of the bottle mouth 2 is provided with an internal thread 24 matched with the external thread 12. The detachable assembly of the bottle body 1 and the bottle mouth 2 can be realized through the clamping of the matched engagement between the external thread 12 and the internal thread 24.

[0025] Further, the bottle mouth 2 and the bottle cap 3 are fixedly connected and sealed through the thread engagement, which is the prior art and does not belong to the main technical problems to be solved in the application, and thus will not be described in detail.

[0026] The sealing ring column 13 is arranged on the top of the bottle mouth 11 and is integrally formed between the sealing ring column 13 and the bottle mouth 11. The sealing cavity 21 is arranged in a ring shape, the sealing convex ring 23 is integrally formed on the inner wall of the sealing cavity 21, and the sealing inclined surface 22 is arranged on the top of the sealing cavity 21.

[0027] When the sealing ring column 13 is located in the sealing cavity 21, the sealing ring column 13 is in interference fit contact with the sealing inclined surface 22 and the sealing convex ring 23, and the cavity 25 is formed between the sealing inclined surface 22 and the sealing convex ring 23.

[0028] In the embodiment, when the ink bottle is sealed, the bottle cap 3 is only arranged on the bottle mouth 2 through the thread engagement. Then, the bottle mouth 2 is arranged on the bottle mouth 11 through the matched engagement between the internal thread 24 and the external thread 12.

[0029] Further, during the arrangement of the bottle mouth 2, the sealing ring column 13 on the bottle body 1 will continuously enter the sealing cavity 21 in the bottle mouth 2 along with the continuous engagement between the internal thread 24 and the external thread 12.

[0030] When the sealing ring column 13 completely enters the sealing cavity 21, the sealing ring column 13 is in interference fit contact with the sealing inclined surface 22 and the sealing convex ring 23. At this time, the horizontal sealing of the bottle body 1 can be realized through the interference sealing between the sealing ring column 13 and the sealing inclined surface 22, and the vertical sealing of the bottle body 1 can be realized through the interference sealing between the sealing ring column 13 and the sealing convex ring 23.

[0031] And at this time, the sealing cavity 25 is formed between the sealing slope 22 and the sealing convex ring 23 through the sealing ring column 13, and the sealing performance of the bottle body 1 can be further ensured through the sealing cavity 25. Through the multiple sealing structure in the scheme, similar sealing effect to the sealing ring and the sealing film can be achieved, so that the sealing ring and the sealing film are not needed in the structure, the cost is saved, and the cumbersome operation of tearing the sealing film by the user at the first use is avoided.

[0032] In the utility model, the sealing ring column 13 is in interference fit with the sealing slope 22 and the sealing convex ring 23 in the sealing cavity 21, the double sealing of the horizontal and vertical directions of the bottle body 1 can be realized, the sealing effect is further enhanced by the sealing cavity 25, the traditional sealing film and the independent sealing ring are omitted in the structure, the material and assembly costs are reduced, the film tearing operation is not needed at the first use of the user, the cover is opened and used, and the convenience and experience are improved.

[0033] The above is only the preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the technical field according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model can be equivalently replaced or changed, and all should be covered in the protection scope of the utility model.
