Description

Technical Field

[0001] This invention relates to the field of containment technology, specifically to a sealed container, and also to an ink bottle. Background Technology

[0002] Because fluids, whether gases or liquids, are fluids, they can easily leak into the external environment through gaps. Therefore, the container must be kept airtight during fluid storage. In existing single-use products where fluids are the primary consumable, a puncture-resistant membrane structure is usually installed at the bottle or tube opening to store and protect the liquid or gas before use, such as during transportation and sale. When in use, the membrane is punctured using an external tip or a pointed part of the cap to allow the liquid or gas inside the product to flow out.

[0003] For example, ink bottles are consumables used in inkjet printers. During use, the printer uses the tip of a syringe to puncture the thin film on the ink bottle to draw the ink stored inside for use in printing. Currently, ink bottles are sealed at the ink outlet with a rubber stopper. Before drawing ink, the printer punctures the film on the rubber stopper to insert itself into the bottle and draw the ink.

[0004] Existing rubber stoppers are generally divided into internal and external types. In the internal type, refer to... Figure 9 Since the rubber stopper 700 is located inside the ink outlet 600, the piercing force generated during the needle piercing the rubber stopper 700 will push the rubber stopper 700 along the inner wall of the ink outlet 600. This may not only push the rubber stopper 700 between the cap and the bottle, but may even result in the inability to pierce it, making it difficult to use the ink bottle.

[0005] Similarly, in the use of some beverages or other products, if the tip is not sharp enough or the rubber stopper is not installed tightly, the film may not be able to be pierced or the stopper may be pushed into the container, causing some inconvenience to the user. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a sealed container to solve the technical problem that the plug is pushed into the container during the puncture process, so as to avoid affecting the use of the container product.

[0007] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0008] A sealing container is provided, comprising: a receiving body having a receiving cavity disposed therein and a first connecting portion disposed thereout, the first connecting portion having a fluid through hole communicating with the receiving cavity; a connecting body including a fluid output portion, a second connecting portion engaging with the first connecting portion, and an internal channel penetrating the second connecting portion and the fluid output portion, the fluid output portion having a fluid output port communicating with the internal channel; and a puncture-resistant sealing plug disposed within the fluid output portion, the puncture-resistant sealing plug comprising a... The fluid outlet includes a sealing portion and a puncturable sealing layer disposed within the sealing portion; and a stop member, the stop member including a through-hole connection portion, a stop portion, and an internal flow channel penetrating the through-hole connection portion and the stop portion, the through-hole connection portion being used to seal the fluid through-hole, wherein, when the through-hole connection portion is sealed on the fluid through-hole and the first connection portion and the second connection portion are engaged, the stop portion abuts against the puncturable sealing plug, or the stop portion is close to the puncturable sealing plug and located in the force direction of the puncturable sealing plug when it is punctured.

[0009] Compared with existing technologies, this sealed container has at least the following beneficial effects: In the direction of the puncture force of the punctureable sealing plug, this sealed container prevents the punctureable sealing plug from entering the internal space of the connector or even the container through the fluid outlet or internal channel, thus effectively avoiding contamination of the liquid or gas inside the sealed container by the punctureable sealing plug. It can also effectively ensure the sealing of the external tip when punctured, so as to allow the syringe to extract liquid or gas and prevent leakage.

[0010] Optionally, a first step is provided at the junction of the fluid outlet and the internal channel, and the blocking part includes a first part disposed in the fluid outlet and a second part disposed in the internal channel, wherein the second part and the first part form a second step for abutting against the first step.

[0011] Optionally, when the through-hole connection is blocked on the fluid through-hole and the first connection and the second connection are engaged, the stop portion pushes against the puncturable sealing plug so that the second step seals against the first step.

[0012] Optionally, the end of the stop portion is provided with a pushing step. When the through hole connection portion is blocked on the fluid through hole and the first connection portion is engaged with the second connection portion, the pushing step pushes against the second part of the blocking portion so that the second step seals against the first step.

[0013] Optionally, the sealing portion has a fluid output channel, the puncturable sealing layer is disposed in the fluid output channel and the sealing portion forms a joint opening facing the stop portion. When the through hole connection portion is sealed on the fluid through hole and the first connection portion is engaged with the second connection portion, the end of the stop portion passes through the joint opening and abuts against the outer edge of the puncturable sealing layer, so that the second step seal abuts against the first step.

[0014] Optionally, the sealing portion has a fluid output channel, the punctureable sealing layer is disposed in the fluid output channel and the sealing portion forms a joint opening facing the stop portion, the inner side of the joint opening is provided with an inner stepped surface, when the through hole connection portion is sealed on the fluid through hole and the first connection portion is engaged with the second connection portion, the end of the stop portion passes through the joint opening and abuts against the inner stepped surface, so that the second step seals against the first step.

[0015] Optionally, the first connecting part has an external thread structure on the outside of the first connecting part, and the second connecting part has an internal thread structure on the inside of the second connecting part, wherein the internal thread structure is adapted to the internal thread structure so that the first connecting part and the second connecting part are engaged.

[0016] Optionally, the sealed container further includes a protective cover, which includes a cover body for receiving the fluid output portion, the cover body being detachably connected to the first connecting portion of the connector or the container.

[0017] Optionally, the through-hole connection portion has a sealing plate and a joint portion protruding from the bottom side of the sealing plate. The joint portion engages with the fluid through-hole and forms a sealing step with the sealing plate. The sealing plate abuts against the outside of the fluid through-hole.

[0018] Optionally, both the fluid through-hole and the sealing plate are circular, the joint is a cone coaxially arranged with the sealing plate, the joint is interference-fitted onto the fluid through-hole, and the diameter D1 of the sealing plate is greater than the maximum diameter D2 of the joint.

[0019] To achieve the above objectives, the present invention also provides an ink bottle, comprising: a bottle body having an ink cavity disposed therein and an outer portion disposed thereout, the outer portion having an ink through hole communicating with the ink cavity; a connector including an ink output portion, an inner portion engaging with the outer portion, and a connecting channel penetrating the inner portion and the ink output portion, the ink output portion having an ink output port communicating with the ink through hole via the connecting channel; and a puncture-resistant stopper disposed within the ink output portion, the puncture-resistant stopper covering... The device includes a plug for sealing the ink outlet and a leak-proof membrane disposed within the plug; and a thrust member, the thrust member including an ink guide portion, a thrust portion, and an ink guide channel penetrating the ink guide portion and the thrust portion, the ink guide portion being used to seal the ink through hole, wherein, when the ink guide portion seals the ink through hole and the outer portion engages with the inner portion, the thrust portion abuts against the puncturable plug, or the thrust portion is close to the puncturable plug and located in the direction of force when the puncturable plug is punctured.

[0020] Compared with existing technologies, this ink bottle has at least the following beneficial effects: This ink bottle utilizes a puncture-resistant stopper to seal the ink inside, preventing leakage during transport and maintaining good ink sealing. When the printer needle punctures the stopper, the thrust member on the thrust block uses the location of the ink guide as the bearing point to hold the stopper in place, preventing it from moving further into the bottle and contaminating the ink. Furthermore, the ink guide channel inside the stop member guides the ink to the ink outlet, preventing ink accumulation and residue in the connecting channel of the connector. Simultaneously, it keeps the stopper in the needle position, maintaining good sealing and preventing waste caused by liquid leakage from the ink outlet and contamination of the printer's internal structure.

[0045] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0046] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0048] The sealed container provided in the embodiments of the present invention will now be described with reference to the accompanying drawings.

[0049] Please see Figures 1 to 8b A sealed container for holding fluids such as beverages, ink, and oxygen includes a container 100, a connector 200, a puncturable sealing plug 300, and a stop 400. The container 100 has a receiving cavity 110 inside, which is used to hold the aforementioned fluids.

[0050] The container 100 has a first connecting portion 120 on its outer side, and a fluid through hole 121 on the first connecting portion 120. The fluid through hole 121 is connected to the container cavity 110 and serves as the outlet for the internal fluid within the container cavity 110. The connector 200 includes a fluid output portion 210, a second connecting portion 220, and an internal channel 230 that passes through the second connecting portion 220 and the fluid output portion 210. The fluid output portion 210 has a fluid output port 211 that communicates with the internal channel 230. The second connecting portion 220 is used to engage with the first connecting portion 120 so that the connector 200 and the container 100 can be detachably connected. In this case, the fluid output port 211 is connected to the fluid through hole 121 through the internal channel 230.

[0051] A puncturable sealing plug 300 is disposed within the fluid output section 210. The puncturable sealing plug 300 includes a sealing portion 310 for sealing the fluid output port 211 and a puncturable sealing layer 320 disposed within the sealing portion 310. The sealing portion 310 is disposed within the fluid output port 211, wherein a fluid output channel 311 is provided within the sealing portion 310, which communicates with the internal channel 230. The puncturable sealing layer 320 is disposed within the fluid output channel 311, thereby preventing the fluid flowing into the fluid output port 211 from flowing out. It should be noted that the puncturable sealing layer 320 is made of a puncturable material such as rubber or sealing paper, and can be a layered or film-like puncturable structure. Its placement on the puncturable sealing plug 300 can be integrally molded or externally fixed, to ensure the sealing of the fluid.

[0052] A stop 400 is disposed between the fluid outlet 211 and the fluid through hole 121. It includes a through hole connection 410, a stop 420, and an inner flow channel 430 that passes through the through hole connection 410 and the stop 420. The through hole connection 410 is used to block the fluid through hole 121, so that the fluid inside the container 100 is restricted from flowing out of the original fluid through hole 121 to flowing out through the inner flow channel 430.

[0053] When the through-hole connection 410 blocks the fluid through-hole 121 and the first connection 120 and the second connection 220 are engaged, i.e., when the container 100, the connector 200, and the stop 400 are in the assembled state, the stop 420 abuts against the puncturable sealing plug 300, bearing the thrust when the puncturable sealing plug 300 is punctured. Alternatively, the stop 420 is close to the puncturable sealing plug 300 and located in the direction of force when the puncturable sealing plug 300 is punctured, so that the puncturable sealing plug 300 has a short-distance buffer movement when punctured, preventing impact damage to the puncture tip, and finally, the stop 420 prevents the puncturable sealing plug 300 from continuing to move, so that the puncturable sealing plug 300 cannot leave the fluid outlet 211. At this time, when the fluid flows out from inside the container 100, it flows out through the inner flow channel 430 into the fluid outlet channel 311, and the inner flow channel 430 guides the fluid.

[0054] Compared with the prior art, this sealed container prevents the puncturable sealing plug 300 from entering the internal space of the connector 200 through the fluid outlet 211 or the internal channel 230, or even into the container 100 through the fluid through hole 121, in the direction of the puncture force of the puncturable sealing plug 300. This effectively avoids the contamination of the liquid or gas inside the sealed container by the puncturable sealing plug 300, and also effectively ensures the sealing of the external tip when punctured, so as to allow the needle to extract liquid or gas and prevent leakage.

[0055] Example 1

[0056] Figure 4a and Figure 4b This is one embodiment of the present invention, in which reference is made to... Figure 4a The puncture-resistant sealing plug 300 is press-fitted onto the fluid outlet 211 of the connector 200. The stop portion 420 of the stop member 400 abuts against the end of the puncture-resistant sealing plug 300 near the internal channel 230. When the external tip punctures the puncture-resistant sealing layer 320 on the puncture-resistant sealing plug 300 along the X direction, refer to... Figure 4b When the puncturable sealing plug 300 is punctured by an external tip, the resulting thrust prevents the stop portion 420 from moving further along the X direction.

[0057] Example 2

[0058] Figure 5a , Figure 5b , Figure 6a , Figure 6b , Figure 7a , Figure 7b , Figure 8a and Figure 9In another embodiment of the present invention, a first step 231 is provided at the junction of the fluid outlet 211 and the internal channel 230. The sealing part 310 includes a first part 312 and a second part 313. A second step 314 is formed between the first part 312 and the second part 313, facing the fluid outlet 211. The first part 312 is located inside the fluid outlet 211 and abuts against the inner wall of the fluid outlet 211. The second part 313 is located inside the internal channel 230 and abuts against the inner wall of the internal channel 230. The second step 314 abuts against the first step 231, thereby sealing the fluid outlet 211. Of course, the sealing part 310 can also seal the fluid outlet 211 simply by the sealing abutment of the second step 314 against the first step 231. In this case, the first part 312 no longer needs to abut against the inner wall of the fluid outlet 211 and / or the second part 313 no longer needs to abut against the inner wall of the internal channel 230. The above method is the internal structure of the puncturable sealing plug 300 on the fluid outlet 210. That is, by utilizing the structural design of the first step 231 and the second step 314, it can prevent the puncturable sealing plug 300 from being removed from the fluid outlet 211, can withstand the pushing force of the internal fluid on the puncturable sealing plug 300, ensure the sealing performance of the puncturable sealing plug 300 to the internal fluid, and also prevent the external tip from being punctured and carried away from the fluid outlet 211.

[0059] In one embodiment of Example 2 above, when the through-hole connection 410 is sealed on the fluid through-hole 121 and the first connection 120 and the second connection 220 are engaged, the stop 420 pushes against the punctureable sealing plug 300 so that the second step 314 seals against the first step 231, thereby clamping the punctureable sealing plug 300 between the first step 231 and the stop 420 and fixing it between the fluid outlet 211 and the stop 400. At this time, the stop 420 applies force to the punctureable sealing plug 300, and the second step 314 and the first step 231 directly generate a corresponding engagement force, improving the sealing effect of the punctureable sealing plug 300 on the fluid outlet 211. When the punctureable sealing plug 300 is made entirely of a deformable material such as rubber, the second step 314 uses its own deformable properties to seal against the first step 231, resulting in a stronger sealing effect on the fluid.

[0060] One preferred option is to refer to Figure 5aThe end of the stop portion 420 is provided with a push step 421. When the through hole connection portion 410 is blocked on the fluid through hole 121 and the first connection portion 120 is engaged with the second connection portion 220, the push step 421 pushes against the second part 313 of the blocking portion 310, so that the stop portion 420 provides a pushing force to the force-applying surface of the puncturable sealing plug 300, so that the second step 314 on the puncturable sealing plug 300 seals against the first step 231. In this preferred embodiment, the push-down step 421 can be sealed to the end face of the second part 313. When the fluid flows through the inner flow channel 430 to the fluid output channel 311 that can puncture the sealing plug 300, it cannot leak from the joint between the push-down step 421 and the second part 313 into the inner channel 230, further ensuring the sealing performance of the sealed container for the fluid and preventing the fluid from accumulating and remaining in the inner channel 230 between the fluid output part 210 and the first connection part 120.

[0061] When the outer tip punctures the punctureable sealing layer 320 on the punctureable sealing plug 300 along the X direction, refer to Figure 5b When the puncturable sealing plug 300 is punctured by an external tip, the resulting thrust prevents the stop portion 420 from moving further along the X direction.

[0062] Another preferred option is to refer to Figure 6a The piercing sealing layer 320 can be pierced in the fluid output channel 311 of the sealing part 310 to form a joint opening 315 in the direction of the stop part 420. When the through hole connection part 410 is blocked on the fluid through hole 121 and the first connection part 120 is engaged with the second connection part 220, the end of the stop part 420 passes through the joint opening 315 and pushes against the outer edge of the piercing sealing layer 320, providing a pushing force so that the first step 231 seals against the second step 314. In this preferred embodiment, the end of the stop portion 420 can be sealed to the outer edge of the punctureable sealing layer 320. When the fluid flows through the inner flow channel 430 to the fluid output channel 311 of the punctureable sealing plug 300, it cannot leak from the junction of the end of the stop portion 420 and the outer edge of the punctureable sealing layer 320 into the inner channel 230. This further ensures the sealing performance of the sealed container for the fluid and prevents the fluid from accumulating and remaining in the inner channel 230 between the fluid output portion 210 and the first connecting portion 120.

[0063] When the outer tip punctures the punctureable sealing layer 320 on the punctureable sealing plug 300 along the X direction, refer to Figure 6b When the puncturable sealing plug 300 is punctured by an external tip, the resulting thrust prevents the stop portion 420 from moving further along the X direction.

[0064] In yet another preferred embodiment, the two preferred methods described above are combined, with reference to... Figure 7a A push-up step 421 is provided at the end of the stop portion 420. When the through hole connection portion 410 is blocked on the fluid through hole 121 and the first connection portion 120 and the second connection portion 220 are engaged, the push-up step 421 pushes against the second part 313 of the blocking portion 310. The end of the stop portion 420 passes through the engagement opening 315 and pushes against the outer edge of the punctureable sealing layer 320, together providing a pushing force so that the first step 231 seals against the second step 314, making the punctureable sealing plug 300 more evenly stressed and achieving a better sealing effect on the fluid outlet 211. In this preferred embodiment, the push-down step 421 can be sealed to the end face of the second part 313. When fluid flows through the inner flow channel 430 to the fluid output channel 311 of the puncturable sealing plug 300, it cannot leak from the joint between the push-down step 421 and the second part 313 into the inner channel 230. Alternatively, the end of the stop part 420 can be sealed to the outer edge of the puncturable sealing layer 320. When fluid flows through the inner flow channel 430 to the fluid output channel 311 of the puncturable sealing plug 300, it cannot leak from the joint between the end of the stop part 420 and the outer edge of the puncturable sealing layer 320 into the inner channel 230. This further ensures the sealing performance of the sealed container for the fluid and prevents fluid from accumulating and remaining in the inner channel 230 between the fluid output part 210 and the first connecting part 120.

[0065] When the outer tip punctures the punctureable sealing layer 320 on the punctureable sealing plug 300 along the X direction, refer to Figure 4b When the puncturable sealing plug 300 is punctured by an external tip, the resulting thrust prevents the stop portion 420 from moving further along the X direction.

[0066] In the alternative scheme of the second preferred method, see [link / reference]. Figure 8a The sealing layer 320 can be punctured in the fluid output channel 311 of the sealing part 310 to form a joint opening 315 in the direction of the stop part 420. The inner side of the joint opening 315 is provided with an inner stepped surface 316. When the through hole connection part 410 is blocked on the fluid through hole 121 and the first connection part 120 is engaged with the second connection part 220, the end of the stop part 420 passes through the joint opening 315 and pushes against the outer edge of the inner stepped surface 316, providing a pushing force so that the first step 231 seals against the second step 314. In this preferred embodiment, the end of the stop portion 420 can be sealed to the inner stepped surface 316. When the fluid flows through the inner flow channel 430 to the fluid output channel 311 that can puncture the sealing plug 300, it cannot leak from the end of the stop portion 420 to the inner stepped surface 316 into the inner channel 230, further ensuring the sealing performance of the sealed container for the fluid and preventing the fluid from accumulating and remaining in the inner channel 230 between the fluid output portion 210 and the first connecting portion 120.

[0067] When the outer tip punctures the punctureable sealing layer 320 on the punctureable sealing plug 300 along the X direction, refer to Figure 8b When the puncturable sealing plug 300 is punctured by an external tip, the resulting thrust prevents the stop portion 420 from moving further along the X direction.

[0068] Of course, the above preferred method can also be combined with the first preferred method to form a new implementation. In addition, other implementation methods can also be used to achieve the stopping and sealing effect of the stop part 420 on the puncturable sealing plug 300. All of these are within the scope of the present invention and will not be described in detail here.

[0069] In another embodiment of the present invention, the first connecting portion 120 has an external thread structure disposed on the outer side of the first connecting portion 120, and the second connecting portion 220 has an internal thread structure disposed on the inner side of the second connecting portion 220. The internal thread structure is adapted to the internal thread structure so that the first connecting portion 120 and the second connecting portion 220 are engaged. By selecting the threaded connection method between the first connecting portion 120 and the second connecting portion 220, the connection sealing of the connecting body 200 on the receiving body 100 can be guaranteed. At the same time, it can also be applied in embodiment 2, where the locking direction of the second connecting portion 220 when threadedly connected to the first connecting portion 120 is the same as the pushing direction of the stop portion 420 against the puncturable sealing plug 300. This allows the pushing force of the stop portion 420 against the puncturable sealing plug 300 to gradually increase during the connection process between the connecting body 200 and the receiving body 100, and ultimately strengthens the sealing of the puncturable sealing plug 300 against the fluid outlet 211.

[0070] Furthermore, the first connecting part 120 and the second connecting part 220 can also achieve a detachable connection between the connecting body 200 and the receiving body 100 through snap-fit ​​connection or other means, all of which are within the scope of the present invention.

[0071] In another embodiment of the present invention, the sealed container further includes a protective cover 500, which includes a cover body 510. The cover body 510 has a third connecting portion 511 disposed at its bottom and a receiving cavity 512 disposed therein. The receiving cavity 512 is used to accommodate the fluid output portion 210 so that the cover body 510 protects the fluid output portion 210. The third connecting portion 511 is detachably connected to the first connecting portion 120 of the connecting body 200 or the receiving body 100.

[0072] Reference Figure 2 and Figure 3The inner side of the third connecting part 511 is provided with an internal connecting thread, and the outer side wall of the second connecting part 220 is provided with an external connecting thread for connecting with the internal connecting thread. The threaded connection can seal the receiving cavity 512 and prevent fluid splashed on the outside of the connecting body 200 from leaking from the connection between the second connecting part 220 and the first connecting part 120.

[0073] In another embodiment of the present invention, the through hole connection portion 410 has a sealing plate 411 and a joint portion 412 protruding outward from the bottom side of the sealing plate 411. The joint portion 412 is fastened to the fluid through hole 121 and forms a sealing step 413 between it and the sealing plate 411. The cross-section of the sealing plate 411 is larger than the cross-section of the fluid through hole 121, so that it abuts against the outside of the fluid through hole 121. At this time, the sealing step 413 blocks the fluid through hole 121, so that the fluid inside the container 100 flows out from the inner flow channel 430.

[0074] Furthermore, the fluid through-hole 121 is a circular through-hole, the sealing plate 411 is a circular plate, and the joint 412 is a cone coaxially arranged with the sealing plate 411. The cone has an inverted frustum structure with a slight tilt angle, which can be 1 to 5°, allowing the minimum diameter of the joint 412 to be inserted into the fluid through-hole 121, while its maximum diameter is larger than the diameter of the fluid through-hole 121. The joint 412 is interference-fitted onto the fluid through-hole 121. In this embodiment, the diameter of the sealing plate 411 is D1, the maximum diameter of the joint 412 is D2, the minimum diameter is D3, and the diameter of the fluid through-hole 121 is D4, wherein D1 > D2 > D4 > D3.

[0075] Of course, the through-hole connection part 410 can also achieve sealing of the sealing plate 411 by other means such as threaded connection, which is also within the scope of the present invention.

[0076] When the fluid contained in the sealed container is ink, the sealed container is implemented as an ink bottle for use as printing feed in an inkjet printer. The ink bottle according to a second aspect embodiment of the present invention will be described below.

[0077] An ink bottle includes a bottle body, a connector, a puncture stopper, and a thrust member. The bottle body has an ink cavity inside and an outer connecting part outside. The ink cavity is used to contain ink. The outer connecting part has an ink through hole communicating with the ink cavity. The connector includes an ink output part, an inner connecting part that engages with the outer connecting part, and a connecting channel penetrating the inner connecting part and the ink output part. The ink output part has an ink outlet that communicates with the ink through hole via the connecting channel. The bottle body and the connector are detachably connected to form the main structure of the ink bottle.

[0078] A puncture-resistant sealing plug is installed inside the ink output section, including a plug body for sealing the ink output port and a leak-proof membrane disposed within the plug body. An ink flow channel is provided in the center of the plug body, and the leak-proof membrane is disposed within the ink flow channel to seal the ink bottle before use. A thrust member includes an ink guide portion, a thrust portion, and an ink guide channel penetrating the ink guide portion and the thrust portion. The ink guide channel is used to seal the ink through-hole, allowing ink in the ink chamber to flow from the ink guide channel to the ink output section.

[0079] Specifically, when the ink guide portion blocks the ink through hole and the outer and inner portions are joined, i.e., when the bottle body is connected to the connector, the thrust portion abuts against the puncture stopper, resisting the puncture stopper in the direction of the puncture force, thus preventing the puncture stopper from moving inward. Alternatively, the thrust portion is close to the puncture stopper and located in the direction of the force when the puncture stopper is punctured, so that after a short buffer distance, the inward movement of the puncture stopper is stopped.

[0080] Compared to existing technologies, this ink bottle utilizes a puncture-resistant stopper to seal the ink inside, preventing leakage during transport and maintaining a good seal. When the printer needle punctures the stopper, the thrust member on the thrust block uses the location of the ink guide as a bearing point to hold the stopper in place, preventing it from moving further into the bottle and contaminating the ink. Furthermore, the ink guide channel inside the stopper directs the ink to the ink outlet, preventing ink buildup and residue within the connector's connection channel. Simultaneously, it holds the stopper in the needle position, maintaining a good seal and preventing waste and contamination of the printer's internal structure caused by leakage from the ink outlet.

[0081] Example 3

[0082] In one embodiment of the ink bottle of the present invention, the punctureable stopper is sealed to the ink outlet of the connector by an interference fit. The thrust portion of the stopper abuts against the end of the punctureable stopper near the connecting channel. When the external tip punctures the leak-proof membrane on the punctureable stopper, the punctureable stopper is subjected to the thrust force generated by the external tip puncturing it. At this time, the thrust portion prevents the punctureable stopper from moving further along the puncture direction.

[0083] Example 4

[0084] In another embodiment of the ink bottle of the present invention, an upper step is provided at the junction of the ink outlet and the connecting channel. The stopper includes an upper stopper and a lower stopper, forming a lower step facing the ink outlet. The upper stopper is disposed within the ink outlet and abuts against the inner wall of the ink outlet, while the lower stopper is disposed within the connecting channel and abuts against the inner wall of the connecting channel. The lower step abuts against the upper step, thereby sealing the ink outlet. Of course, the stopper can also seal the ink outlet solely through the sealing abutment of the lower step against the upper step. In this case, the upper stopper no longer necessarily abuts against the inner wall of the ink outlet, and / or the lower stopper no longer necessarily abuts against the inner wall of the connecting channel. The above method is an internal structure of the puncture stopper on the ink output section. It uses an upper and lower stepped structure design to prevent the puncture stopper from being removed from the ink output port. It can withstand the pushing force of the internal ink on the puncture stopper, ensure the sealing of the puncture stopper to the internal ink, and prevent the external tip from being punctured and carried away from the ink output port.

[0085] In one embodiment of Example 5 above, when the ink guide portion blocks the ink through-hole and the outer connecting portion engages with the inner connecting portion, the thrust portion pushes against the punctureable plug to make the lower step seal against the upper step, so that the punctureable plug is clamped by the upper step and the thrust portion and thus fixed between the ink outlet and the stop member. At this time, the thrust portion applies force to the punctureable plug, and the lower step and the upper step directly generate a corresponding engagement force, improving the sealing effect of the punctureable plug on the ink outlet. When the punctureable plug is made entirely of a deformable material such as rubber, the lower step uses its own deformable properties to seal against the upper step, and its sealing effect on the ink is even stronger.

[0086] In one preferred embodiment, the end of the thrust portion is provided with a pushing step. When the ink guide portion is sealed on the ink through-hole and the outer connecting portion is engaged with the inner connecting portion, the pushing step pushes against the lower plug of the plug body, serving as the force-applying surface of the thrust portion on the punctureable plug body, providing a pushing force so that the lower step on the punctureable plug body seals against the upper step. In this preferred embodiment, the pushing step can be sealed with the end face of the lower plug body. When ink flows through the ink guide channel to the ink output channel of the punctureable plug body, it cannot leak from the joint between the pushing step and the lower plug body into the connecting channel, further ensuring the ink bottle's seal against the ink and preventing ink from accumulating and remaining in the connecting channel between the ink output portion and the outer connecting portion.

[0087] When the external tip punctures the leak-proof membrane on the puncture plug, the puncture plug is subjected to the thrust generated by the puncture by the external tip. At this time, the thrust stop prevents the puncture plug from moving further in the puncture direction.

[0088] In another preferred embodiment, the leak-proof membrane forms a joint opening in the ink output channel of the stopper, facing the thrust portion. When the ink guide portion blocks the ink through-hole and the outer connecting portion engages with the inner connecting portion, the end of the thrust portion passes through the joint opening and pushes against the outer edge of the leak-proof membrane, providing a thrusting force to seal the upper step against the lower step. In this preferred embodiment, the end of the thrust portion can be sealed with the outer edge of the leak-proof membrane. When ink flows through the ink guide channel to the ink output channel that can puncture the stopper, it cannot leak from the joint between the end of the thrust portion and the outer edge of the leak-proof membrane into the connecting channel, further ensuring the ink bottle's seal against the ink and preventing ink accumulation and residue in the connecting channel between the ink output portion and the outer connecting portion.

[0089] In another preferred embodiment, the two preferred methods described above are combined, with a pushing step provided at the end of the thrust portion. When the ink guide portion is blocked on the ink through hole and the outer connecting portion is engaged with the inner connecting portion, the pushing step pushes against the lower plug of the plug body. The end of the thrust portion passes through the joint opening and pushes against the outer edge of the leak-proof membrane, providing a pushing force so that the upper step seals against the lower step, making the puncture plug body more evenly stressed and achieving a better sealing effect on the ink outlet. In this preferred embodiment, the push-down step can be sealed to the end face of the lower stopper, so that when ink flows through the ink guide channel to the ink output channel of the puncturable stopper, it cannot leak from the joint between the push-down step and the lower stopper into the connecting channel; or, the end of the thrust portion can be sealed to the outer edge of the leak-proof membrane, so that when ink flows through the ink guide channel to the ink output channel of the puncturable stopper, it cannot leak from the joint between the end of the thrust portion and the outer edge of the leak-proof membrane into the connecting channel, further ensuring the ink bottle's seal on the ink and preventing ink from accumulating and remaining in the connecting channel between the ink output section and the outer connecting section.

[0090] In the alternative of the second preferred embodiment, the leak-proof membrane forms a joint opening in the ink output channel of the stopper, oriented towards the thrust portion. The inner side of this joint opening has an inner stepped surface. When the ink guide portion seals the ink through-hole and the outer connecting portion engages with the inner connecting portion, the end of the thrust portion passes through the joint opening and pushes against the outer edge of the inner stepped surface, providing a thrusting force to seal the upper step against the lower step. In this preferred embodiment, the end of the thrust portion can seal against the inner stepped surface. When ink flows through the ink guide channel to the ink output channel that can puncture the stopper, it cannot leak from the end of the thrust portion and the joint of the inner stepped surface into the connecting channel, further ensuring the ink bottle's seal against the ink and preventing ink accumulation and residue in the connecting channel between the ink output portion and the outer connecting portion.

[0091] Of course, the above preferred method can also be combined with the first preferred method to form a new implementation. In addition, other implementation methods can also be used to achieve the blocking and sealing effect of the thrust portion on the puncturable plug. All of these are within the scope of the present invention and will not be elaborated here.

[0092] In another embodiment of the invention, the outer connecting part has an external thread structure located on its outer side, and the inner connecting part has an internal thread structure located on its inner side. The internal thread structure is adapted to the internal thread structure so that the outer connecting part and the inner connecting part engage. Using a threaded connection between the outer connecting part and the inner connecting part ensures the sealing of the connector on the thrust member. Furthermore, this method can also be applied in Embodiment 5, where the locking direction of the inner connecting part when threaded onto the outer connecting part is the same as the pushing direction of the thrust member against the puncturable stopper. This gradually increases the pushing force of the thrust member against the puncturable stopper during the connection process between the connector and the bottle, ultimately strengthening the seal of the puncturable stopper on the ink outlet.

[0093] Furthermore, the outer connecting part and the inner connecting part can also achieve a detachable connection between the connector and the bottle body through snap-fit ​​connections or other means, all of which are within the scope of the present invention.

[0094] In another embodiment of the present invention, the ink bottle further includes a protective cap, the protective cap including a cap body, the cap body having a cap connecting portion at its bottom and a receiving cavity inside therein, the receiving cavity being used to accommodate the ink output portion so that the cap body protects the ink output portion, the cap connecting portion being detachably connected to a connector or an outer connecting portion of the bottle body.

[0095] The inner side of the cap connector is provided with an internal connecting thread, and the outer side wall of the inner connector has an external connecting thread for connecting with the internal connecting thread. The threaded connection can seal the storage cavity and prevent ink splashed on the outside of the connector from leaking from the connection between the inner and outer connectors.

[0096] In another embodiment of the invention, the ink guide portion has a baffle and a joint portion protruding outward from the bottom side of the baffle. The joint portion engages with the ink through hole and forms a blocking step between it and the baffle. The cross-section of the baffle is larger than the cross-section of the ink through hole, thereby abutting against the outside of the ink through hole. At this time, the blocking step blocks the ink through hole, allowing the ink inside the bottle to flow out from the ink guide channel.

[0097] Furthermore, the ink through-hole is a circular through-hole, the baffle is a circular plate, and the joint is a cone coaxially arranged with the baffle. The cone has an inverted frustum structure with a slight tilt angle, which can be 1 to 5°. The minimum diameter of the joint can be inserted into the ink through-hole, and its maximum diameter is greater than the diameter of the ink through-hole. The joint is interference-fitted onto the ink through-hole. In this embodiment, the diameter of the baffle is D5, the maximum diameter of the joint is D6, the minimum diameter is D7, and the diameter of the ink through-hole is D8, wherein D5 > D6 > D8 > D7.

[0098] Of course, the ink guide can also achieve sealing of the baffle through other means such as threaded connection, which is also within the scope of this invention.

[0099] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
