[0031] In existing technologies, ink bottle caps have complex structures. During the ink filling process, the ink nozzle often requires the coordination of spring mechanisms, limiting mechanisms, buttons, etc. within the ink bottle cap to control the opening and closing of the ink bottle cap's opening. This results in complex operating steps during the ink filling process and also increases the manufacturing cost of the ink bottle cap.

[0032] Based on this, this utility model provides a bottle cap and an ink bottle for sealing ink bottles. It features an inner cap structure and a self-closing sealing assembly. The inner cap structure includes a top surface and a side wall, forming an inner cap opening. The top surface has an ink filling opening and an ink conveying component. The ink conveying component is a hollow cylinder, with its lower opening connecting to the bottom of the top surface. The ink conveying component serves as a transmission interface for supplying ink from the ink bottle to the printer. The self-closing sealing assembly is nested between the inner cap opening and the inner cap structure. It has a self-closing opening connected to the ink filling opening, serving as a self-closing channel for filling the ink bottle. This allows direct control of the connection between the cap and the ink bottle, eliminating the need for complex mechanical devices. This simplifies the ink filling process and reduces the cap manufacturing cost. Furthermore, the ink conveying component, compatible with the printer, optimizes the ink supply process from the ink bottle to the printer.

[0033] Therefore, the embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0034] Reference Figure 1 and Figure 2 As shown, Figure 1 This is an exploded view of a bottle cap for sealing ink bottles provided in some embodiments of this utility model. Figure 2 This is a bottom view of the inner cap structure provided in some embodiments of the present invention. The cap 1000 for sealing the ink bottle 2000 is provided with an inner cap structure 1100 and a self-closing sealing component 1200.

[0035] The inner cover structure 1100 includes an inner cover top surface 1110 and an inner cover side wall 1120. The inner cover top surface 1110 and the inner cover side wall 1120 form an inner cover opening. The inner cover top surface 1110 is provided with an ink filling opening 1111 and an ink conveying component 1112. The ink conveying component 1112 is a hollow cylinder. The lower opening of the ink conveying component 1112 connects to the bottom of the inner cover top surface 1110. The ink conveying component 1112 is used as a transmission interface for ink bottle 2000 to supply ink to the printer. Thus, based on the ink conveying component 1112 adapted to the printer, the steps of ink bottle 2000 supplying ink to the printer are optimized.

[0036] Furthermore, the self-closing sealing assembly 1200 is based on the inner cap opening and the inner cap structure 1100 being interlocked. The self-closing sealing assembly 1200 is provided with a self-closing opening 1210, which is connected to the ink filling opening 1111. The self-closing opening 1210 is used as a self-closing channel for filling the ink bottle 2000 with ink. Thus, the connection between the bottle cap 1000 and the ink bottle 2000 can be directly controlled based on the self-closing sealing assembly 1200. When the external inkjet printhead fills the ink bottle 2000 with ink, the external inkjet printhead can be directly inserted into the self-closing sealing assembly 1200 for filling. After the filling is completed, the external inkjet printhead leaves the self-closing sealing assembly 1200. At this time, the self-closing sealing assembly 1200 returns to its original closed state due to elastic deformation, thus eliminating the need for complex mechanical devices for connection and opening control, simplifying the steps of filling the ink bottle 2000 with ink, and reducing the manufacturing cost of the bottle cap 1000.

[0037] Furthermore, the self-closing sealing assembly 1200 includes a sealing base 1220 and a protruding member 1230, the protruding member 1230 being disposed above the sealing base 1220, and the self-closing opening 1210 being disposed on the top surface of the protruding member 1230.

[0038] Furthermore, the self-closing sealing assembly 1200 is also provided with an ink supply hole 1240. The ink supply hole 1240 is located on the top surface of the protruding member 1230. The ink supply hole 1240 is connected to the lower opening of the ink supply member 1112, so that the ink in the ink bottle 2000 can be transferred to the ink supply member 1112 through the ink supply hole 1240. Then, the ink supply member 1112 is inserted into the ink supply end of the printer to transfer ink to the printer.

[0039] Furthermore, refer to Figure 1 and Figure 3 As shown, Figure 3 This is a bottom view of a self-closing sealing assembly provided in some embodiments of the present invention. The interior of the protruding component 1230 is a hollow cavity. The upper part of the hollow cavity is connected to the self-closing opening 1210 and the ink supply hole 1240, respectively. The sealing base 1220 has a base hole 1221 in the middle, which is connected to the lower part of the hollow cavity. The base hole 1221 is used as a connecting component for the ink bottle 2000, thereby connecting the self-closing opening 1210 and the ink supply hole 1240 to the ink bottle 2000 through the base hole 1221 and the hollow cavity, respectively.

[0040] It is worth noting that the self-closing sealing assembly 1200 is made of plastic, which allows the self-closing sealing assembly 1200 to provide sufficient elastic deformation when the external inkjet printhead leaves the self-closing sealing assembly 1200.

[0041] Furthermore, the inner cover sidewall 1120 is provided with a plurality of first threads 1121 and a plurality of second threads 1122. Each first thread 1121 is provided on the outer wall surface of the inner cover sidewall 1120, and each second thread 1122 is provided on the inner wall surface of the inner cover sidewall 1120. The first threads 1121 are vertical threads, and the second threads 1122 are horizontal threads. The first threads 1121 are used to increase the rotational friction of the inner cover structure 1100, and the second threads 1122 are used as fitting parts for the ink bottle 2000, thereby improving the detachability between the bottle cap 1000 and the ink bottle 2000.

[0042] Furthermore, the bottle cap 1000 also includes an outer cap structure 1300, which includes an outer cap top surface 1310 and an outer cap side wall 1320. The outer cap top surface 1310 and the outer cap side wall 1320 form an outer cap opening. The inner cap structure 1100 is detachably connected to the outer cap structure 1300 based on the outer cap opening. The bottom of the outer cap top surface 1310 is fitted with the upper opening of the ink supply component 1112.

[0043] Furthermore, the outer wall surface of the outer cover sidewall 1320 is provided with a plurality of screw grooves 1321. The screw grooves 1321 are used to increase the rotational friction of the outer cover structure 1300, which can improve the detachability between the outer cover structure 1300 and the inner cover structure 1100.

[0044] Secondly, referring to Figure 4 As shown, Figure 4 This is an exploded view of an ink bottle provided in some embodiments of the present invention. The present invention also proposes an ink bottle 2000, which includes a bottle cap 1000 and a bottle body 2100 as described in the first aspect above. The bottle body 2100 includes a bottle mouth 2120 and a bottle cavity 2130. The outer surface of the bottle mouth 2120 is provided with a bottle mouth thread 2121, which is engaged with the second thread 1122 of the inner cap structure 1100 of the bottle cap 1000.
