Description

Technical Field

[0001] The utility model belongs to the technical field of printer ink bottles, in particular to an ink bottle which prevents ink leakage. Background Art

[0002] In daily study and work, ink bottles are an important component of writing tools and are widely used in stationery such as pens. However, during the production and use of ink bottles, especially during transportation, ink bottles often face leakage problems caused by factors such as temperature changes and external impact. When the ink bottle is exposed to high temperatures, the liquid inside the ink may generate vapor pressure, which can cause the sealing film to bulge upward. When the ink bottle encounters bumps or rough handling during transportation, the liquid in the bottle will continuously impact the film, and in severe cases, it may even cause the film to rupture, causing ink leakage. This not only affects product quality but also causes inconvenience to users. Most existing ink bottles use simple sealing structures, such as rubber stoppers or plastic caps to seal the bottle mouth. However, these structures often cannot effectively cope with the complex situations during transportation. Moreover, with people's increasing awareness of environmental protection, the requirements for packaging materials are becoming increasingly stringent. This requires ink bottles to not only have good sealing performance but also consider the sustainability of the packaging. Therefore, it is necessary to design an ink bottle that can prevent ink leakage during transportation. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides an ink bottle structure which prevents ink leakage, thereby eliminating the possibility of leakage due to bulging of the sealing film of the ink bottle during transportation.

[0019] The embodiments of the present invention are described in detail below. Figures 1 to 3 , an embodiment of the present invention provides an ink bottle 100 for preventing ink leakage, comprising: an ink chamber 100, an ink supply nozzle 200 and a sealing film 300, the ink supply nozzle 200 can be rotatably sleeved on the bottle mouth 110 of the ink chamber 100, the sealing film 300 is fixed to the bottle mouth 110, an anti-collision device 210 is provided in the ink supply nozzle 200, the anti-collision device 210 protrudes from the inner end surface 220 of the ink supply nozzle 200, when the ink supply nozzle 200 rotates relative to the ink chamber 100, it can drive the anti-collision device 210 to move upward or downward, after the ink supply nozzle 200 and the ink chamber 100 are tightened, the anti-collision device 210 is located above the sealing film 300, when the sealing film 300 is not bulging, the anti-collision device 210 does not contact the sealing film 300, when the sealing film 300 is bulging, the anti-collision device 210 contacts its surface, and the anti-collision device 210 can limit the upward movement of the sealing film 300. By setting one or more raised anti-collision walls inside the ink supply nozzle 200 of the ink bottle, the sealing film 300 is prevented from excessively bulging due to the increase in internal pressure, thereby preventing the sealing film 300 from being torn. The sealing film 300 is effectively prevented from bulging due to the increase in internal pressure during transportation of the ink bottle, thereby avoiding the sealing film 300 from rupturing and ink leakage. This not only improves the product reliability and user experience, but also reduces environmental pollution and resource waste caused by ink leakage.

[0020] Furthermore, the ink chamber 100 is a device for containing ink, referring to Figure 2 The ink supply nozzle 200 can be rotatably sleeved on the ink cavity 100. The ink supply nozzle 200 has a through hole 240 so that the ink in the ink cavity 100 can flow into the printer. Of course, the present invention does not limit the specific connection structure of the ink cavity 100 and the ink supply nozzle 200. Preferably, the upper part of the ink cavity 100 is provided with a first thread 120. Figure 1The inner wall of the ink supply nozzle 200 is provided with a second thread 230. The first thread 120 and the second thread 230 can be tightened to fix the ink supply nozzle 200 to the upper end of the ink cavity 100 to ensure the sealing of the ink bottle. The sealing film 300 is fixed to the bottle mouth 110 of the ink cavity 100. Of course, the utility model does not limit the specific fixing method of the sealing film 300 and the bottle mouth 110. Preferably, the sealing film 300 is fused with the bottle mouth 110 of the ink cavity 100 by hot melting to form a sealed end face to ensure that the ink does not leak. Furthermore, the ink supply nozzle 200 is fixed to the upper end of the ink cavity 100 to ensure the sealing of the ink bottle. An anti-collision device 210 is provided in the ink nozzle 200, which can limit the upward movement of the sealing film 300. Of course, the utility model does not limit the specific position of the anti-collision device 210. Preferably, the anti-collision device 210 protrudes from the inner end surface 220 of the ink supply nozzle 200. When the ink supply nozzle 200 rotates relative to the ink cavity 100, it can drive the anti-collision device 210 to move upward, or drive the anti-collision device 210 to move downward. When the ink supply nozzle 200 and the ink cavity 100 are tightened, the anti-collision device 210 is located above the sealing film 300.

[0021] Furthermore, the vaporization phenomenon generated by the liquid in the ink chamber 100 under a high temperature environment will cause the sealing film 300 to bulge upward. Coupled with the bumpy transportation route and violent express delivery methods, the liquid will continuously impact the film upward. In severe cases, the film will be torn and leak. At this time, the raised anti-collision fence can prevent the sealing film 300 from bulging upward too much, thereby avoiding pulling the fusion surface of the sealing film 300 and the sealing end surface of the bottle mouth 110 when bulging, and thus preventing the sealing film 300 from being torn, thereby preventing ink leakage. Of course, the present invention is not limited to the specific structure of the anti-collision device 210. Preferably, the anti-collision device 210 is a single protrusion, and the area of ​​the single protrusion is larger than the area of ​​the bottle mouth 110, so that when the sealing film 300 bulges, the single protrusion can apply a uniform load to the sealing film 300, thereby preventing the sealing film 300 from breaking due to uneven force. Of course, the anti-collision device 210 can also be multiple protrusions, refer to Figure 3 , multiple protrusions form an anti-collision fence, and there is a cavity in the anti-collision fence. The diameter of the cavity is smaller than the diameter of the bottle mouth 110, so that the anti-collision fence can apply a uniform load to the surface of the sealing film 300, thereby preventing the sealing film 300 from breaking due to uneven force under the structure of multiple protrusions. Furthermore, the utility model does not limit the specific connection method between the anti-collision device 210 and the ink supply nozzle 200. Preferably, the anti-collision device 210 and the ink supply nozzle 200 are made in an integral molding manner. Of course, the anti-collision device 210 and the ink supply nozzle 200 are movably connected, such as screwed or clipped, to adapt to different models of ink bottles.
