Transverse and axial double-layer sealing structure of ink bottle
By using a double-layer sealing structure in both the lateral and axial directions, the ink bottle forms a double seal by utilizing the contact between the outer ring and the end face of the bottle mouth and the interference fit between the inner ring and the inner cavity of the bottle mouth. This enhances the sealing performance of the ink bottle and solves the problem of poor sealing performance in traditional ink bottles.

AI Technical Summary
Traditional ink bottles rely on a single contact surface for sealing, and their sealing performance depends heavily on the manufacturing precision of the cap and the user's tightening force, resulting in poor sealing.
The ink bottle adopts a double-layer sealing structure with both lateral and axial sealing. The axial seal is achieved by the outer ring contacting the end face of the bottle mouth, while the lateral seal is achieved by the inner ring interfering with the inner cavity of the bottle mouth. The sealing performance is further enhanced by a temporarily formed cavity.
It achieves a double seal between the bottle mouth and the bottle cap, improving sealing performance and solving the problem of poor sealing performance of traditional ink bottles.

[0020] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0021] Referring to Figures 1-6 A kind of ink bottle transverse and axial double -layer sealing structure, including bottle body 1, bottle nozzle 2 and bottle cap 3, the cylindrical bottle mouth 21 is provided on the bottle nozzle 2, and sealing ring 211 is provided on bottle mouth 21.Bottle cap 3 is respectively provided with the outer ring 31 and inner ring 32 of adaptive sealing corresponding bottle mouth 21, slope 321 is provided on inner ring 32, and compartment 33 is separately provided between outer ring 31 and inner ring 32.
[0022] The bottle body 1, the bottle nozzle 2 and the bottle cap 3 are modularly arranged in a split mode, and the bottle body 1, the bottle nozzle 2 and the bottle cap 3 are all provided with threads that are adapted to engage with each other and are connected through thread engagement.
[0023] The end surface of the bottle mouth 21 is in contact with the outer ring 31, the outer ring 31 is provided with a sealing groove 311, and the sealing groove 311 is adapted to the sealing ring 211. Through the adaptation and sealing between the sealing ring 211 and the sealing groove 311, the axial sealing between the bottle mouth 21 and the bottle cap 3 can be achieved.
[0024] The inner cavity 212 is formed in the bottle mouth 21, and the inner ring 32 is in contact with the inner cavity 212. Through the adaptation and sealing between the inner wall of the inner cavity 212 and the outer wall of the inner ring 32, the transverse sealing between the bottle mouth 21 and the bottle cap 3 can be achieved.
[0025] The outer wall of the inner ring 32 is provided with an annular slope 321, and the slope 321 is contracted from top to bottom. Through the setting of the annular slope, the outer wall of the inner ring 32 is essentially a slope. In this way, when the inner ring 32 is inserted into the inner cavity 212, the outer wall of the inner ring 32 and the inner cavity 212 will form an interference contact, thereby improving the sealing performance of the transverse sealing.
[0026] The slope 321 is provided with a groove 322, and the groove 322 is adapted to the bottle mouth 21. Through the setting of the groove 322, the interference locking of the bottle mouth 21 can be achieved, so as to further ensure the sealing performance between the bottle mouth 21 and the inner ring 32.
[0027] In this embodiment, the bottle body 1, the bottle nozzle 2 and the bottle cap 3 are modularly arranged in a split mode, and the bottle body 1, the bottle nozzle 2 and the bottle cap 3 are all provided with threads that are adapted to engage with each other and are connected through thread engagement.
[0028] When the bottle nozzle 2 and the bottle cap 3 are sealed and installed, the bottle cap 3 is only needed to be installed on the bottle nozzle 2 through thread engagement, so as to realize the sealing between the bottle cap 3 and the bottle mouth 21.
[0029] When the bottle cap 3 is installed, the outer ring 31 on the bottle cap 3 will be in contact with the end surface of the bottle mouth 21, so that the sealing ring 211 can be adapted to be clamped in the sealing groove 311, so as to realize the axial sealing between the bottle mouth 21 and the bottle cap 3.
[0030] The inner ring 32 is also gradually inserted into the inner cavity 212, and the transverse sealing between the bottle mouth 21 and the bottle cap 3 can be realized through the adaptive sealing between the inner wall of the inner cavity 212 and the outer wall of the inner ring 32. And through the setting of the slope surface 321 and the groove 322, the transverse sealing performance between the bottle mouth 21 and the bottle cap 3 can be further improved.
[0031] When the bottle cap 3 is completely installed on the bottle mouth 2, the outer ring 31 is in contact sealing with the end face of the bottle mouth 21, and the inner ring 32 is in contact sealing with the inner wall of the bottle mouth 21. At this time, the annular separation cavity 33 is formed between the outer ring 31 and the inner ring 32. Since the temporarily formed separation cavity 33 is also sealed, the sealing performance of the product can be further ensured through the setting of the separation cavity 33.
[0032] In the utility model, the axial sealing is realized through the contact between the outer ring 31 and the end face of the bottle mouth 21, the transverse sealing is realized through the interference fit between the inner ring 32 and the inner cavity 212 of the bottle mouth 21, the transverse and axial double-layer sealing structure can be formed between the bottle mouth 2 and the bottle cap 3, the sealing performance can be further enhanced through the temporarily formed separation cavity 33, and the problem of poor sealing performance of the single contact surface on the bottle cap 3 of the traditional ink bottle is solved.
