Description

Technical Field

[0001] This utility model relates to the field of printer technology, and in particular to an ink bottle. Background Technology

[0002] In existing one-piece molded ink bottles, the nozzle and sealing plug are typically fitted together by setting the angle between the end face of the nozzle near the ink outlet and the peripheral wall to 90 degrees. The sealing plug is perpendicular to the nozzle, or the bottle mouth is directly blow-molded with a vertical opening, and a subsequent thermo-press sealing method is used to form the vertical angle. This prevents the ink supply needle from being pulled out after inverted filling and pulling out the sealing plug. When using the former method (the sealing plug is perpendicular to the nozzle), the sealing plug may be difficult to insert from the nozzle, and the sealing plug may deform significantly. When using the latter method (the bottle mouth is vertically molded by injection / blow molding, and a subsequent thermo-press sealing method is used to form the vertical angle), there are more processes and the cost is higher.

[0036] like Figure 1 As shown, an inkjet printer (not shown) includes an ink tank 20 that contains ink. This ink tank is connected to the ink supply tube of the inkjet printer, allowing ink to be supplied from the ink tank 20 to the print head of the printer, thus enabling inkjet printing on a recording medium (e.g., paper). The ink tank 20 can be located outside or inside the inkjet printer. There can be one or more ink tanks 20, and multiple ink tanks 20 can be arranged along their width. Multiple ink tanks 200 each contain inks of different colors. For example, multiple ink tanks 200 may contain black ink, yellow ink, magenta ink, and cyan ink, respectively. Alternatively, multiple ink tanks 20 may contain ink of the same color.

[0037] like Figure 1As shown, the ink tank 20 is provided with an ink storage cavity 21 for storing ink from the ink bottle 10. Above the ink storage cavity 21 is an ink inlet 22, and an ink supply needle 23 is provided inside the ink inlet 22. The ink tank 20 is used in an upright position, with its axis along the plumb line. When the ink in the ink tank 20 is empty or the ink volume is low, the ink bottle 10 can be connected to the ink tank 20 to inject ink from the ink bottle 10 into the ink storage cavity 21. In the connected state, the ink bottle 10 is inserted into the ink inlet 22 in an inverted position, and the ink supply needle 23 is inserted into the ink bottle 10. The axis of the ink bottle 10 overlaps with or is parallel to the axis of the ink tank.

[0038] like Figures 2 to 4 As shown, this embodiment provides an ink bottle 10 for refilling ink into an ink canister 20. The ink bottle 10 includes a bottle body, a sealing component 14, and a cap 13. The bottle body includes an integrally formed bottle body 11 and a bottle nozzle 12. The bottle body 11 is flat and has an internal space for containing ink. A support portion 111 is provided in the middle of the bottle body 11 to support it. Optionally, the support portion 111 can also partially penetrate the bottle body 11. It can be formed by recessing into one or two opposite surfaces of the bottle body 11 to serve as the support portion 111. The two recesses can be connected or not connected. One end of the bottle body 11 is open, and its open end is connected to the bottle nozzle 12. The ink in the bottle body 11 flows out through the bottle nozzle 12. The bottle body 11 and the bottle mouth 12 are integrally formed and connected by a connecting part 112. The bottom of the bottle body 113 is provided opposite to the connecting part 112. The connecting part 112 and the bottom of the bottle body 113 are nearly flat and are connected to the connecting part 112. A contact part 114 is provided near the bottle mouth. The contact part 114 extends at least partially along a direction perpendicular to the connecting part 112. This arrangement makes it easy to place the ink bottle 10 stably and prevents it from tipping over.

[0039] like Figure 5 As shown, the nozzle component 12 is a hollow tubular structure. The end of the nozzle component 12 away from the bottle body component 11 is provided with an ink outlet for ink to flow out. Viewed from the outside, the nozzle component 12 includes a first part 121, a second part 122 and a third part 123. The first part 121 is located away from the bottle body component 11, and the ink outlet is specifically located in the first part 121. The third part 123 is located close to the bottle body component 11, and its outer peripheral wall has an external thread 123a. The second part 122 is located between the first part 121 and the third part 123, and the inner diameter of the second part 122 is less than or equal to the inner diameter of the first part 121.

[0040] Specifically, such as Figure 6 , Figure 7As shown, a receiving space 125 is provided in the first part 121 of the bottle nozzle 12 near the ink outlet. The inner end face of the first end of the receiving space 125 near the ink outlet extends obliquely along the inner peripheral wall 121c of the receiving space 125 towards the central axis A near the ink outlet, forming an inclined surface 121a. The angle between the inclined surface 121a and the inner peripheral wall 121c of the receiving space 125 is greater than 90 degrees, which facilitates the insertion of the sealing component 14 from the ink outlet. In a specific implementation, the inner end face of the first end near the ink outlet can be blown into an inclined surface 121a by a direct blow molding process. This facilitates the insertion of the sealing component 14 while allowing for free deformation space of the sealing component 14. The sealing component 14 is subjected to less pressure from the end face of the first end, making it less prone to damage. Furthermore, the direct blow molding process for forming the inclined surface 121a involves fewer steps, which can reduce costs.

[0041] like Figure 6 and Figure 7 As shown, the second end of the receiving space 125 protrudes from the inner peripheral wall 121c of the receiving space 125 in the direction of the central axis A perpendicular to the ink outlet, and forms an abutting end face 121b, that is, a stepped structure is formed at the connection position of the first part 121 and the second part 122, and the abutting end face 121b is the end face of the stepped structure facing the ink outlet direction.

[0042] like Figure 6 and Figure 7 As shown, the sealing component 14 is disposed within the receiving space 125 of the nozzle component 12. When the sealing component 14 is placed into the receiving space 125 from the ink outlet, one end of the sealing component 14 abuts against the inclined surface 121a, and the other end abuts against the abutting end surface 121b.

[0043] like Figures 8-10 As shown, the sealing component 14 has a first segment 141, a second segment 142, and a third segment 143 arranged sequentially. The first segment 141 is furthest from the bottle body 11, the third segment 143 is closest to the bottle body 11, and the second segment 142 is located between the first segment 141 and the third segment 143. The first segment 141, the second segment 142, and the third segment 143 can be a one-piece molded structure. The outer diameter of the second segment 142 is larger than the outer diameters of the first segment 141 and the second segment 143, respectively.

[0044] like Figures 8-10As shown, the end of the first segment 141 away from the second segment 142 is provided with a first end face 141c. Opposite to the first end face 141c of the first segment 141 is a second end face 145, which is located at the end of the third segment 143 away from the second segment 142. The end of the second segment 142 away from the third segment 143 is provided with a third end face 142b. Preferably, the third end face 142b is parallel to the first end face 141c, and the third end face 142b and the third end face 141c are perpendicular to the central axis A of the ink outlet. The sealing component 14 is also provided with a valve plate 144, which is located on the inner side wall of the end of the third segment 143 away from the second segment 142. The valve plate 144 is provided with a self-closing notch (not shown in the figure). The self-closing notch can be a straight notch, a cross notch, a star notch, etc. In the absence of external force, the self-closing notch can be closed by its own elasticity, so that the sealing component 14 can seal the ink outlet.

[0045] Specifically, such as Figure 6 As shown, when the sealing member 14 is installed into the receiving space 125, the first end face 141c and / or the third end face 142b abut against the inclined surface 121a (usually the third end face 142b abuts against the inclined surface 121a, but there are also cases where the first end face 141c and the third end face 142b abut against the inclined surface 121a at the same time or the first end face 141c abuts against the inclined surface 121a), and the second end face 145 abuts against the abutting end face 121b.

[0046] In some other embodiments, the first end face 141c and the third end face 142b are configured as inclined surfaces that are not parallel to the central axis A of the ink outlet, and the first end face 141c and the third end face 142b are connected to form an inclined surface that abuts against the inclined surface 121a when the sealing member 14 is installed into the receiving space 125.

[0047] like Figure 10 As shown, the sealing component 14 is also provided with at least one rib. Specifically, a rib 142a is provided on the outer peripheral wall of the second segment 142, and a rib 143a is provided on the outer peripheral wall of the third segment 143. The ribs can be complete annular ribs or multiple short ribs on the same circumference. Multiple layers of ribs can also be provided axially on the outer peripheral walls of the second segment 142 and / or the third segment 143. When the sealing component 14 is installed in the receiving space 125, the ribs 142a and 143a abut against the inner peripheral wall 121c of the receiving space 125. This arrangement can prevent the sealing component 14 from moving up and down along the central axis A of the ink outlet.

[0048] like Figure 7 and Figure 9As shown, the inner diameter of the second part 122 of the nozzle component 12 is slightly larger than the outer diameter of the ink supply needle 23 and smaller than the inner diameter of the first part 121. A protrusion 141a is also provided on the inner wall of the sealing component 14. The protrusion 141a is farther from the second part 122 than the valve plate 144, meaning it is located near the ink outlet but lower than it. Preferably, at least two protrusions 141a are provided, and an air channel 141b is provided between adjacent protrusions 141a. When the ink bottle 10 is connected to the ink tank 20, the interior of the second part 122 abuts against the ink supply needle 23 in any radial direction, while the protrusion 141a also abuts against the outer peripheral wall of the ink supply needle 23. Furthermore, external air can enter the bottle body through the air channel 141b. This arrangement, on the one hand, ensures stable positioning between the ink bottle 10 and the ink tank 20, preventing the ink bottle 10 from tilting, and on the other hand, accelerates the ink filling speed, achieving ink filling. Alternatively, the protrusion 141a can also be a ring protrusion with a notch, which is the air passage 141b, and multiple notches can be made.

[0049] In addition, when the ink supply needle 23 passes through the self-closing cut of the valve plate 144 of the sealing component 14, part of the valve plate 144 will abut against the inner peripheral wall of the second part 122 under the pressure of the ink supply needle 23, thereby forming a positioning of the ink bottle 10.

[0050] Furthermore, the ink supply needle 23 can indirectly abut against the inner peripheral wall of the second part 122 through the valve plate 144. Specifically, the valve plate 144 has a thickness in the axial direction when it is closed. When the ink supply needle 23 passes through the self-closing cut, the valve plate 144 will be squeezed open and wrapped around the outer peripheral wall of the ink supply needle 23. At this time, in any radial direction, the inner diameter of the second part 122 will be equal to the sum of the outer diameter of the ink supply needle 23 and twice the thickness of the valve plate 144 of the sealing component. After the valve plate 144 is pushed open, its thickness in the axial direction is converted into its width in the radial direction. In the same radial direction, both sides of the ink supply needle 23 are wrapped with valve plates 144. Therefore, the outer diameter of the ink supply needle 23 plus twice the thickness of the valve plate 144 is equal to the inner diameter of the second part 122. The ink supply needle 23 abuts against the inner peripheral wall of the second part 122 (or indirectly abuts against the inner peripheral wall of the second part 122 through the valve plate 144 of the sealing member 14), which can play a positioning role for the ink bottle 10 in the connected state. Without setting any other positioning part or locking part, the ink bottle 10 and the ink tank 20 can be tightly locked together, the connection is stable, and ink leakage is prevented.

[0051] Alternatively, since the valve plate 144 is elastic, it can be squeezed by the ink supply needle 23 and the second part 122, i.e., compressed and sandwiched between the two. When the valve plate 144 is compressed, its thickness will decrease, i.e., the inner diameter of the second part 122 can be less than the sum of the outer diameter of the ink supply needle 23 and twice the thickness of the valve plate 144, but at least the inner diameter of the second part 122 must be greater than or equal to the sum of the outer diameter of the ink supply needle 23 and the thickness of the valve plate 144 of the sealing component.

[0052] like Figure 2 , Figure 3 , Figures 11 to 13 As shown, the ink bottle 10 also includes a cap 13, which has an opening at one end and is fitted onto the nozzle member 12 through the opening. Specifically, the cap 13 is detachably installed onto the nozzle member 12, and the inner peripheral wall 132 of the cap 13 has an internal thread 132a that mates with the external thread 123a of the nozzle member 12 (located on the outer peripheral wall of the third segment 123). When the cap 13 is installed onto the nozzle member 12, the cap 13 at least partially abuts against the sealing member 14 to ensure a seal between the sealing member 14 and the ink outlet. The bottle cap 13 has a top end 131 and a bottom end 133 that communicate with the inner peripheral wall 132. The bottom end 133 is one end of the bottle cap 13 opening, and the top end 131 is the other end opposite to the bottom end 133. A protrusion 1311 extending towards the bottom end 133 is provided at the middle position of the top end 131. The protrusion 1311 has an outer peripheral surface 1311a. When the bottle cap 13 is connected to the bottle mouth part 12, the protrusion 1311 is at least partially inserted into the space of the sealing member 14 and makes interference contact with the inner peripheral wall of the sealing member 14, but will not penetrate into the valve plate 144, so that the sealing member 14 can better seal the ink outlet and ensure a stable seal between the bottle cap 13 and the bottle mouth part 12.

[0053] like Figures 11 to 13 As shown, the bottom end 133 has an abutment surface 133a, and a plurality of teeth 134 are spaced apart on the inner peripheral wall near the bottom end 133. The teeth 134 have an end face 134a parallel to the abutment surface 133a. The teeth 134 are used to support the bottom end 133 of the bottle cap 13 and prevent deformation.

[0054] like Figures 11 to 13As shown, when the bottle cap 13 is connected to the bottle nozzle 12, the internal thread 132a on the bottle cap 12 is threadedly connected to the external thread 123a on the bottle nozzle 12. The bottom end 133 on the bottle cap abuts against the abutting portion 114 on the bottle body 11. That is, at least part of the abutting surface 133a on the bottom end 133 abuts against the end face on the abutting portion 114, so that the bottle cap 13 can be stably abutted against the bottle body 11. At the same time, the protrusion 1311 on the top end 131 of the bottle cap 13 is inserted into the space of the sealing member 14. At least part of the outer peripheral surface 1311a of the protrusion 1311 abuts against the inner peripheral wall of the sealing member 14 to seal and prevent ink from flowing out of the ink outlet.

[0055] When using the ink bottle 10 of this embodiment to replenish ink to the ink tank 20, the ink bottle 10 is inverted and then moved toward the ink inlet 22. The ink supply needle 23 on the ink tank 20 passes through the ink outlet and the self-closing cut on the sealing component 14 and communicates with the ink storage cavity 110 of the bottle body 11. After the valve plate 144 is squeezed open, it wraps around the ink supply needle 23. The ink supply needle 23 abuts against the inner peripheral wall of the second part 122 through the valve plate 144, forming a stable connection. The ink in the ink storage cavity 110 is replenished into the ink storage cavity 21 of the ink tank 20 through the ink supply needle 23.

[0056] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
