[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely in conjunction with the drawings of the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0022] Referring to Figures 1-7 A kind of ink bottle high sealing transverse and axial sealing structure, including bottle nozzle 1 and bottle cap 2, bottle nozzle 1 is installed with bushing 31 by bushing seat 3, and the top in bottle cap 2 is fixedly arranged with extruding piece 21 adapted with bushing 31. Columnar bottle mouth 11 is provided on bottle nozzle 1, and inclined plane 22 and sealing ring 23 are provided on extruding piece 21, and inclined plane 22 and sealing ring 23 are all in contact with bottle mouth 11 and sealed.

[0023] ​​The sleeve seat 3 is fixedly installed on the inner wall of the bottle mouth 11, and the sleeve 31 is installed on the sleeve seat 3. The sleeve 31 is provided with an annular mounting portion 32, and the mounting portion 32 is connected with the sleeve seat 3. Through the arrangement of the sleeve seat 3, the installation of the sleeve 31 can be realized. The sleeve 31 is made of flexible material, and the ink passes through the outer edge of the sleeve 31. After the ink bottle is poured, the liquid in the ink bottle presses on the sleeve 31, so that the sleeve 31 expands outward, so as to increase the pressure of the interference portion of the sleeve 31, and the sealing performance is better. And through the arrangement of the mounting portion 32, the deformation performance of the sleeve 31 can be guaranteed, so as to further guarantee the pressure of the interference portion of the sleeve 31.

[0024] The annular inclined surface 22 is arranged on the extrusion piece 21, and the inclined surface 22 is in contact with the inner wall top end surface of the bottle mouth 11. Through the contact sealing between the inclined surface 22 and the inner wall top end surface of the bottle mouth 11, the axial sealing of the bottle mouth 11 can be realized.

[0025] The annular sealing ring 23 is arranged on the extrusion piece 21, and the sealing ring 23 is in contact with the inner wall of the bottle mouth 11. Through the contact sealing between the sealing ring 23 and the inner wall of the bottle mouth 11, the lateral sealing of the bottle mouth can be realized.

[0026] The cross section of the sealing ring 23 is a downwardly inclined semi-elliptical shape, and when the extrusion piece 21 is in contact with the bottle mouth 11, a temporary cavity 24 is formed between the inclined surface 22 and the sealing ring 23. When the sealing ring 23 is in lateral sealing with the inner wall of the bottle mouth 11, the sealing ring 23 will deform, so that the structure is a line-to-face interference fit, and the pressure at the sealing position is increased, and the sealing effect is better.

[0027] In this embodiment, the bottle nozzle 1 and the bottle cap 2 are provided with matching threads, and the engagement and installation of the bottle nozzle 1 and the bottle cap 2 can be realized through the thread engagement. This is a prior art, so it will not be described in detail.

[0028] When the bottle cap 2 is installed, the bottle cap 2 is only needed to be installed on the bottle nozzle 1 through thread engagement, so that the sealing of the bottle mouth 11 can be realized. During the installation of the bottle cap 2, the axial sealing of the bottle mouth 11 can be realized through the contact sealing between the inclined surface 22 and the inner wall top end surface of the bottle mouth 11. The lateral sealing of the bottle mouth can be realized through the contact sealing between the sealing ring 23 and the inner wall of the bottle mouth 11.

[0029] When the bottle cap 2 is installed, a sealed cavity 24 is formed between the inclined surface 22 and the sealing ring 23, and the sealing performance of the product can be further improved through the arrangement of the cavity 24. After the installation of the sealing ring 23, the sealing ring 23 will deform upwardly due to interference, and the deformation of the sealing ring 23 can compress the cavity 24, so as to further enhance the sealing performance of the cavity 24, and further improve the sealing performance.

[0030] Further, after the ink bottle is poured, the liquid inside the ink bottle presses on the bushing 31, so that the bushing 31 expands outward, thereby increasing the pressure of the interference of the bushing 31, and the sealing is more effective.

[0031] In the utility model, the axial sealing is realized through the contact between the inclined surface 22 and the top end surface of the inner wall of the bottle mouth 11, the transverse sealing is formed through the contact between the sealing ring 23 and the inner wall of the bottle mouth 11, and the temporary cavity 24 is formed between the two, and the interference sealing is enhanced by the expansion of the bushing 31 under pressure when pouring, thereby solving the problem of poor sealing and easy leakage caused by the single contact surface of the traditional ink bottle, and the sealing effect of the ink bottle is improved.

[0032] The above is only the preferred specific implementation mode of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art should be covered in the protection scope of the utility model according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, and the equivalent replacement or change of the utility model is carried out.
