Description

Technical Field

[0001] The utility model relates to the field of printing consumables, in particular to a film-breaking piece of a printer ink bottle and the printer ink bottle. Background Art

[0002] The printer is equipped with ink cartridges for ink supply and printing. When there is a need for large-scale printing, the existing ink cartridge capacity is no longer sufficient. In order to reduce the frequency of replacing the ink cartridge, an ink bottle is generally used to refill the ink cartridge without having to remove the ink cartridge.

[0003] Existing ink bottles for refilling printer cartridges typically include a bottle body with a thin film covering the bottle opening, a bottle cap mounted on the outside, and a membrane rupture member inside the bottle cap for puncturing the membrane. To operate, the entire ink bottle is placed upside down in the printer, and the bottle cap is lowered to connect to a conduit connected to the printer cartridge. The conduit is inserted through the opening of the bottle cap and pushes the membrane rupture member to puncture the membrane, allowing the ink to flow into the conduit. The membrane rupture member of this ink bottle comprises a hollow cylinder with multiple extension plates extending from one end of the cylinder toward the center. The extension plates converge to form a tip, which punctures the membrane, allowing the ink to flow through the gaps between the extension plates, through the cylinder, and ultimately into the conduit.

[0004] However, when the ink bottle is inverted and the tip of the membrane-breaking member pierces the membrane upward, the opening of the membrane is located at the tip, and the ink can only flow out from this center. In addition, the membrane-breaking member will stay at this center when piercing the membrane, which has a certain blocking effect on the area through which the ink flows. The area where the ink can circulate is very small, which seriously affects the ink flow rate and makes the ink discharge unstable. Utility Model Content

[0005] The first purpose of the utility model is to provide a membrane breaker for a printer ink bottle.

[0006] The second purpose of the utility model is to provide a printer ink bottle.

[0007] The first purpose of the present utility model is to provide a membrane rupture member for releasing the seal of a sealing membrane covering and sealing the bottle mouth of a printer ink bottle. The membrane rupture member is arranged inside the bottle cap of the printer ink bottle. The membrane rupture member is tubular with an extension direction perpendicular to the sealing membrane. One end of the membrane rupture member in the extension direction is provided with a membrane rupture portion for puncturing the sealing membrane. In the extension direction, the membrane rupture member includes a circumferential edge close to one end of the sealing membrane. The circumferential edge includes a first part and a second part sequentially arranged along the circumference of the bottle cap. The membrane rupture portion is a plurality of spikes arranged on the first part and protruding continuously toward the sealing membrane. The second part is not provided with spikes.

[0008] As can be seen from the above scheme, the membrane rupture element replaces the centrally located tip of the membrane piercing element with one located circumferentially within the tubular membrane rupture element, significantly increasing the opening area to the membrane. The end of the membrane rupture element is divided into a first portion with a spike and a second portion without a spike. When the membrane rupture element pierces the membrane, the membrane in the first portion is cut, while the membrane in the second portion is not cut and remains connected to the main membrane layer. The cut membrane deflects toward the uncut membrane, similar to the effect of opening a lid, significantly increasing the cross-sectional area through which ink can flow, greatly increasing the ink flow rate and preventing clogging. In addition, since a portion of the membrane is left uncut, the cut piece of membrane can remain connected to the main membrane layer after being cut, preventing it from falling off, thus preventing the detached membrane from clogging the catheter.

[0009] The second object of the present utility model is to provide a printer ink bottle for supplying ink outward through an external conduit, comprising a membrane rupture member and a bottle body and a bottle cap combined with each other, the bottle body containing ink, the bottle body comprising a sealing membrane covering and sealing the bottle body opening, the membrane rupture member being arranged inside the bottle cap, the end of the bottle cap away from the bottle body being provided with a socket for inserting the conduit, when the conduit is inserted into the bottle cap from the socket, the membrane rupture member will be forced to move and puncture the sealing membrane so that the ink in the bottle body can flow into the conduit, the membrane rupture member is tubular with an extension direction perpendicular to the sealing membrane, the membrane rupture member comprises a circumferential edge near one end of the sealing membrane, the circumferential edge comprising a first part and a second part sequentially arranged along the circumference of the bottle cap, the first part being provided with a plurality of spikes continuously protruding toward the sealing membrane, the second part being provided with no spikes, the spikes being used to puncture the sealing membrane.

[0010] As can be seen from the above scheme, the membrane rupture element replaces the centrally located tip of the membrane piercing element with one located circumferentially within the tubular membrane rupture element, significantly increasing the opening area to the membrane. The end of the membrane rupture element is divided into a first portion with a spike and a second portion without a spike. When the membrane rupture element pierces the membrane, the membrane in the first portion is cut, while the membrane in the second portion is not cut and remains connected to the main membrane layer. The cut membrane deflects toward the uncut membrane, similar to the effect of opening a lid, significantly increasing the cross-sectional area through which ink can flow, greatly increasing the ink flow rate and preventing clogging. In addition, since a portion of the membrane is left uncut, the cut piece of membrane can remain connected to the main membrane layer after being cut, preventing it from falling off, thus preventing the detached membrane from clogging the catheter.

[0011] A preferred solution is that the circumferential arc of the second portion along the circumferential edge accounts for more than one-fifth and less than one-half.

[0012] It can be seen from this that leaving at least one-fifth and no more than one-half of the sealing film uncut can reduce the probability of the cut sealing film falling off, prevent clogging of the catheter, and avoid cutting too little of the sealing film, resulting in insufficient flow.

[0013] A further solution is that the spike includes a first edge and a second edge extending from the tip thereof along the circumferential direction of the circumferential edge and away from the sealing membrane, and the helix angle of the second edge is smaller than the helix angle of the first edge.

[0014] It can be seen that along the spiral extension direction described in this scheme, the first edge is sharper and steeper, while the second edge is flatter, so that the film can be broken smoothly while being cut smoothly when cutting the film, preventing the film from being not lifted up due to cutting too quickly, and preventing small film residues from clogging the catheter and contaminating the ink due to cutting too quickly.

[0015] A further solution is that a first convex ring is provided on the inner wall of the bottle cap, and a locking protrusion is provided on the outer wall of the membrane rupture member. The first convex ring cooperates with the locking protrusion and restricts the membrane rupture member from moving toward the sealing membrane.

[0016] It can be seen that the cooperation between the convex ring and the clamping protrusion restricts the membrane rupture component during transportation of the ink bottle to avoid puncturing the membrane. When the ink bottle is used, the pressure of the catheter can cause the membrane rupture component to break through the restriction of the convex ring and puncture the membrane.

[0017] A further solution is that a blocking block is provided on the inner wall of the bottle cap protruding toward the sealing membrane, and the blocking block is closer to the sealing membrane than the spike.

[0018] It can be seen that the blocking block can prevent the film from bulging upward due to the evaporation of ink due to heat during high-temperature transportation, thereby avoiding tearing of the film.

[0019] A further solution is that the membrane breaker includes a first tube section close to the sealing membrane and a second tube section away from the sealing membrane, the inner diameter of the first tube section is larger than the inner diameter of the second tube section, and the circumferential edge is located at one end of the first tube section close to the sealing membrane.

[0020] It can be seen that the inner diameter of the second tube section is similar to the inner diameter of the catheter, which facilitates the abutment and pushing of the catheter. At the same time, the first tube section is set larger, which makes the tip range wider and the opening area larger to avoid blockage.

[0021] A further solution is that the membrane rupturing member is provided with a flow slot communicating with the inner and outer sides thereof, and the flow slot extends between the tube wall of the first tube section and the tube wall of the second tube section.

[0022] It can be seen that the longer flow slots are provided so that the ink can flow out fully, avoiding the accumulation and waste of ink between the membrane rupture piece and the inner wall of the bottle cap.

[0023] A further solution is to further include an outer cover which is detachably mounted on the outside of the bottle cap, and an inner wall of the outer cover is provided with a sealing plug. When the outer cover is mounted on the bottle cap, the sealing plug cooperates with the socket and seals the socket.

[0024] As can be seen, since the end of the bottle cap has a socket for inserting a catheter, when a bottle of ink is not completely used up but the ink cartridge is full, the ink bottle cannot be resealed, resulting in ink contamination and inability to refill the ink bottle, resulting in waste. Under this solution, when the ink bottle is not completely used up, the outer cap and the sealing plug on the inner wall of the outer cap can seal the socket of the bottle cap for the next use.

[0025] A further solution is to further include a self-sealing component, which is located between the insert and the membrane breaker. A second convex ring is provided on the inner wall of the bottle cap, which cooperates with the self-sealing component and limits the movement of the self-sealing component. The catheter can compress and pass through the self-sealing component. An extension body is also provided on the inner wall of the outer cover in the center of the sealing plug. When the outer cover is put on the bottle cap, the extension body abuts against the opening of the self-sealing component.

[0026] It can be seen that the self-sealing component can have a certain blocking effect on the flow of ink and prevent ink from overflowing. The outer cover not only includes a sealing plug that can block the socket, but also has a smaller extension body arranged in the center of the sealing plug to abut and support the central opening of the self-sealing component, thereby further preventing ink from overflowing from the self-sealing component when the ink bottle is stored.

[0035] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0036] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0037] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0038] Example 1: This example provides a printer ink bottle, such as Figures 1 to 3 As shown, it includes a bottle cap 1 and a bottle body 2 containing ink for supplying ink to a printer. The bottle mouth 21 of the bottle body 2 is covered and sealed by a sealing film 3. The bottle cap 1 is screwed onto the bottle mouth 21 of the bottle body 2. A membrane breaker 4 is also provided inside the bottle cap 1. There is a socket 11 on the top of the bottle cap 1. When in use, the ink bottle is turned upside down and the printer catheter is inserted into the socket 11 from bottom to top. The catheter will abut and push the membrane breaker 4 upward to pierce the sealing film 3. The ink in the bottle body 2 will flow out to the catheter and be supplied to the printer. In this embodiment, as Figure 3 As shown, a first protruding ring 12 is provided on the inner wall of the bottle cap 1, while a plurality of retaining protrusions 41 are provided on the outer wall of the membrane rupture member 4. The outermost ends of the retaining protrusions 41 extend beyond the innermost side of the first protruding ring 12. Therefore, the first protruding ring 12 and retaining protrusions 41 cooperate to restrict the membrane rupture member 4 from moving toward the sealing membrane 3. Only when the catheter pushes the membrane rupture member 4 will the retaining protrusions 41 be forced to pass over the first protruding ring 12 under pressure, thereby puncturing the sealing membrane 3. In addition, a plurality of blocking blocks 13 are provided on the inner wall of the bottle cap 1, extending toward the sealing membrane 3. When the membrane rupture member 4 has not passed over the first protruding ring 12, the blocking blocks 13 are closer to the sealing membrane 3, effectively preventing the sealing membrane 3 from bulging.

[0039] In this embodiment, if Figure 5 and Figure 6As shown, the membrane breaker 4 is not extended in a direction perpendicular to the tubular shape of the sealing membrane 3, and the ink can flow out along the hollow part of the tubular shape in the middle axis of the membrane breaker 4. When the ink bottle is placed upright, the lower part of the membrane breaker 4 is close to one end of the sealing membrane 3 and has a circumferential edge 42. The circumferential edge 42 is provided with a continuous first part 43 and a continuous second part 44 connected end to end along the circumference of the bottle cap 1, a total of two parts, wherein the first part 43 is provided with a plurality of spikes 45 that are continuously raised toward the sealing membrane 3, and the second part 44 is not provided with spikes 45. The spikes 45 can be used to puncture the sealing membrane 3 under the pressure of the catheter. It should be noted that the circumferential curvature of the second part 44 without spikes 45 in this embodiment along the circumferential edge 42 accounts for one third of the entire circumferential curvature, ensuring that the sealing membrane 3 is not completely divided. In addition, as Figure 5 and Figure 6 As shown, the spike 45 includes a first edge 451 and a second edge 452 that gradually extend spirally along the tip of the spike 45 along the circumferential direction of the circumferential edge 42 and away from the sealing membrane 3. When the ink bottle is placed upright, the helix angle of the second edge 452 with the horizontal plane is smaller than the helix angle of the first edge 451, making the second edge 452 relatively flat, while the first edge 451 is almost perpendicular to the plane of the sealing membrane 3 and relatively sharp.

[0040] In this embodiment, if Figure 5 and Figure 6 As shown, the membrane breaker 4 includes a first tube segment 46 proximal to the sealing membrane 3 and a second tube segment 47 distal to the sealing membrane 3. The inner diameter of the first tube segment 46 is larger than that of the second tube segment 47, and the circumferential edge 42 is located at the end of the thicker first tube segment 46 proximal to the sealing membrane 3. Furthermore, the membrane breaker 4 has three flow slots 48 extending from the wall of the first tube segment 46 and the wall of the second tube segment 47 for connecting the inside and outside of the membrane breaker 4.

[0041] Example 2: The printer ink bottle provided in this embodiment further includes an outer cover 5 detachably mounted on the upper part of the bottle cap 1 on the basis of Example 1. Figure 7 As shown, a sealing plug 51 is provided on the inner wall of the outer cover 5. When the outer cover 5 is put on the bottle cap 1, the sealing plug 51 is just inserted into the socket 11 and cooperates with the socket 11. The sealing plug 51 can seal the socket 11 to prevent ink from flowing out of the socket 11.

[0042] In addition, in this embodiment, Figure 1 and Figure 3As shown, a self-sealing member 6 is provided between the socket 11 and the membrane breaker 4. A soft opening 61 is provided in the center of the self-sealing member 6, making it difficult for liquid to flow out of the bottle body 2 through the self-sealing member 6. A second protruding ring 14 is also provided on the inner wall of the bottle cap 1. The inner diameter of the second protruding ring 14 is also smaller than the outer diameter of the self-sealing member 6, which can confine the self-sealing member 6 there to prevent it from moving. The catheter can pass through the central opening 61 of the self-sealing member 6 and push the membrane breaker 4. Furthermore, the membrane breaker 4 also includes a third tube segment 49 at its top. The outer diameter of the third tube segment 49 is smaller than that of the second tube segment 47, and can be sleeved onto the inner diameter of the self-sealing member 6, thereby improving the coordination of the entire device structure. When the catheter is inserted through the central opening 61 of the self-sealing member 6, it can also just abut against the top of the third tube segment 49, thereby pushing the membrane breaker 4. In this embodiment, the inner wall of the outer cover 5 is further provided with an extension body 52 at the center of the sealing plug 51. When the outer cover 5 is mounted on the bottle cap 1, the sealing plug 51 just blocks the socket 11, and the extension body 52 just extends into the bottle cap 1 from the center of the socket 11 and abuts against the opening 61 of the self-sealing component 6.

[0043] The above embodiment merely represents one embodiment of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be based on the appended claims.
