Technical Field

[0002] The present application relates to the technical field of printers, and in particular to an ink bottle. Background Art

[0003] Printers are widely used as an important part of office automation. The printer is equipped with an ink tank that can hold ink. The ink tank is connected to an ink supply pipe of the printer, so that ink can be supplied from the ink tank to the printer's print head, thereby performing inkjet printing on a recording medium (such as paper).

[0004] In the prior art, an ink bottle is used to refill ink tanks. The ink bottle comprises a bottle body and a sealing component. The bottle body comprises an integrally formed body and mouthpiece. The end face of the mouthpiece near the ink outlet is angled 90° with the inner circumference of the mouthpiece. The sealing component passes through the ink outlet and abuts against the end face of the mouthpiece near the ink outlet. During production, the end face of the mouthpiece near the ink outlet is first formed vertically by blow molding and then heat-sealed to a perpendicular angle.

[0005] However, when the sealing component is installed with the bottle mouth, the sealing component will be greatly deformed, and the sealing component will be subjected to a large abutment pressure from the end face of the bottle mouth close to the ink outlet, causing the sealing component to be easily damaged, affecting the sealing performance of the sealing component.

DETAILED DESCRIPTION

[0051] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0052] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0053] In this application, unless otherwise specified or limited, the terms "installed," "connected," "fixed," and the like should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections, electrical connections, or communication between them; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0054] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0055] In the above description, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0056] As described in the background art, when the sealing component is installed with the bottle mouth piece, it will cause significant deformation of the sealing component. Furthermore, the sealing component is subjected to high abutment pressure from the bottle mouth piece's end face near the ink outlet, which can easily damage the sealing component and affect its sealing performance. The inventors have discovered that this problem arises because the bottle mouth piece has a small accommodating space, which causes significant deformation of the sealing component when installed with the bottle mouth piece. Furthermore, the angle between the bottle mouth piece's end face near the ink outlet and its inner circumference is set at 90°. This results in high abutment pressure from the bottle mouth piece's end face near the ink outlet when the sealing component is installed with the bottle mouth piece. This can easily damage the sealing component and affect its sealing performance.

[0057] To address the aforementioned issues, an embodiment of the present application provides an ink bottle, comprising a bottle body and a sealing component. The bottle body is provided with a mouthpiece, the mouthpiece having an ink outlet for ink to flow out and a receiving space disposed proximate the ink outlet, the receiving space having an inclined surface and an abutting surface. The volume of the receiving space is increased by positioning the end of the receiving space of the ink bottle mouthpiece proximate the central axis of the ink outlet closer to the ink outlet than the end of the receiving space distal to the central axis of the ink outlet. This reduces deformation of the sealing component when the sealing component is mounted on the mouthpiece, and reduces abutment pressure on the sealing component from the inclined surface of the mouthpiece, thereby making the sealing component less susceptible to damage and ensuring the sealing performance of the sealing component.

[0058] The ink bottle provided in the embodiments of the present application is described in detail below with reference to specific embodiments.

[0059] As shown in Figure 1, a printer (not shown) is provided with an ink tank 20 for containing ink, which is connected to the ink supply tube of the printer so that ink can be supplied from the ink tank 20 to the print head of the printer, thereby performing inkjet printing on a recording medium (e.g., paper). The ink tank 20 can be arranged outside the printer or inside the printer. The ink tank 20 can be arranged as one or more ink tanks, and multiple ink tanks 20 can be arranged along the width direction thereof. Multiple ink tanks 20 respectively contain inks of different colors. For example, multiple ink tanks 20 respectively contain black ink, yellow ink, magenta ink, and cyan ink. In addition, there is also a case where multiple ink tanks 20 contain inks of the same color.

[0060] As shown in FIG1 , the ink tank 20 is provided with an ink storage chamber 21 for storing ink from the ink bottle 10 (see FIG2 ). An ink inlet 22 is located above the ink storage chamber 21, and an ink supply needle 23 is disposed within the ink inlet 22. The ink tank 20 is in an upright position during use, with its axial direction aligned with the plumb bob. When the ink in the ink tank 20 is depleted or the ink level is low, the ink bottle 10 can be connected to the ink tank 20 to inject the ink from the ink bottle 10 into the ink storage chamber 21. In this connected state, the ink bottle 10 is inserted in an inverted position into the ink inlet 22, and the ink supply needle 23 is inserted into the interior of the ink bottle 10, with the axial direction of the ink bottle 10 overlapping or parallel to the axial direction of the ink tank 20.

[0061] As shown in FIG. 2 to FIG. 6 , an embodiment of the present application provides an ink bottle 10 for replenishing ink into an ink tank 20 of a printer. The ink tank 20 is provided with an ink supply needle 23 for ink to flow into.

[0062] The ink bottle 10 includes a bottle body and a sealing component 14 . The bottle body is provided with a bottle mouth 12 . The bottle mouth 12 has an ink outlet 1201 for ink to flow out and a receiving space 1202 communicated with the ink outlet 1201 .

[0063] As shown in Figure 7, the accommodating space 1202 has an inclined surface 121a and an abutting surface 121b. The inclined surface 121a is closer to the ink outlet 1201 than the abutting surface 121b, and the end of the inclined surface 121a close to the central axis A of the ink outlet 1201 (see Figure 4) is closer to the ink outlet 1201 than the end away from the central axis of the ink outlet 1201.

[0064] The sealing member 14 is disposed within the accommodation space 1202, with both ends of the sealing member 14 abutting against the inclined surface 121a and the abutting surface 121b, respectively. Specifically, when the sealing member 14 is placed from the ink outlet 1201 into the accommodation space 1202, one end of the sealing member 14 abuts against the inclined surface 121a, and the other end abuts against the abutting surface 121b.

[0065] The bottle body is further provided with a bottle body part 11 integrally formed with a bottle mouth part 12 .

[0066] As shown in FIG3 , the bottle body 11 is flat and has a space for holding ink therein. A support portion 111 is provided in the middle thereof and extends through the bottle body 11 to support the bottle body 11. The support portion 111 may be a support rod. In other embodiments, the support portion 111 may extend partially through the bottle body 11. Alternatively, the support portion 111 may be formed by inwardly recessing one surface or two opposing surfaces of the bottle body 11. The two recesses may be connected or disconnected.

[0067] One end of the bottle body 11 is open, and the open end is connected to the bottle mouth 12. Ink in the bottle body 11 flows out through the bottle mouth 12. As shown in FIG4 , a connecting surface 112 is provided at the integral connection between the bottle body 11 and the bottle mouth 12. A bottle body bottom surface 113 (see FIG6 ) is provided opposite the connecting surface 112. The connecting surface 112 and the bottle body bottom surface 113 are substantially planar. An abutment portion 114 is provided in communication with the connecting surface 112 and near the bottle mouth 12. The abutment portion 114 extends at least partially in a direction perpendicular to the connecting surface 112. This arrangement facilitates the stable placement of the ink bottle 10 and prevents it from tipping over.

[0068] As shown in Figure 5, the cross section of the bottle mouth 12 is circular. The bottle mouth 12 is a hollow tubular structure. The end of the bottle mouth 12 away from the bottle body 11 is provided with an ink outlet 1201 for ink to flow out.

[0069] As shown in Figure 7, the accommodating space 1202 also has an inner circumferential surface 121c, which is connected between the inclined surface 121a and the abutting surface 121b in the axial direction of the ink outlet 1201. The inclined surface 121a extends obliquely along the inner circumferential surface 121c toward the central axis A of the ink outlet 1201 (see Figure 4). The inclined surface 121a is not perpendicular to the inner circumferential surface 121c, and the outer circumferential wall of the sealing part 14 abuts against the inner circumferential surface 121c.

[0070] As shown in Figures 6 and 7, the accommodating space 1202 has a first end facing the ink outlet 1201 and a second end away from the ink outlet 1201. The inner end face of the first end of the accommodating space 1202 extends obliquely along the inner circumferential surface 121c of the accommodating space 1202 toward the central axis A close to the ink outlet, forming an inclined surface 121a. The angle between the inclined surface 121a and the inner circumferential surface 121c of the accommodating space 1202 is greater than 90°, which facilitates the insertion of the sealing component 14 from the ink outlet 1201. In practice, the inner end surface of the first end facing the ink outlet 1201 can be blown into an inclined surface 121a through a direct blow molding process. This facilitates the placement of the sealing member 14 while also increasing the volume of the accommodating space 1202. This reduces deformation of the sealing member 14 when assembled with the bottle mouth 12, and reduces the abutment pressure exerted by the inclined surface 121a on the bottle mouth 12, thereby preventing damage to the sealing member 14 and ensuring its sealing performance. Direct blow molding to form the inclined surface 121a reduces the number of steps and reduces costs. In this embodiment, the inner circumferential surface 121c is cylindrical.

[0071] In a possible embodiment, as shown in FIG8 , the sealing component 14 includes a first section 141 , a second section 142 and a third section 143 arranged in sequence, and the outer diameter of the second section 142 is larger than the outer diameters of the first section 141 and the third section 143 .

[0072] The sealing component 14 may be made of rubber and may have a circular cross section.

[0073] In the axial direction of the ink outlet 1201, the first section 141 is farthest from the bottle body 11, the third section 143 is closest to the bottle body 11, and the second section 142 is located between the first section 141 and the third section 143. The first section 141, the second section 142 and the third section 143 can be an integrally molded structure.

[0074] As shown in Figure 10, the end face of the first section 141 away from the second section 142 is the first end face 141c, and opposite to the first end face 141c of the first section 141 is the second end face 145. The second end face 145 is arranged at the end of the third section 143 away from the second section 142, and the end face of the second section 142 away from the third section 143 is the third end face 142b.

[0075] When the sealing member 14 is installed in the accommodating space 1202, the first end surface 141c and / or the third end surface 142b abut against the inclined surface 121a. Specifically, when the sealing member 14 is installed in the accommodating space 1202, the first end surface 141c may abut against the inclined surface 121a; or, when the sealing member 14 is installed in the accommodating space 1202, the third end surface 142b may abut against the inclined surface 121a; or, when the sealing member 14 is installed in the accommodating space 1202, the first end surface 141c and the third end surface 142b may simultaneously abut against the inclined surface 121a.

[0076] The first end surface 141c is parallel to the third end surface 142b, and both the first end surface 141c and the third end surface 142b are perpendicular to the central axis A of the ink outlet 1201. In other embodiments, the first end surface 141c and the third end surface 142b are coplanar, and the first end surface 141c and the third end surface 142b are connected to form an inclined surface. The inclined surface is not parallel to the central axis A of the ink outlet 1201, and the angle between the inclined surface and the central axis A of the ink outlet 1201 is less than 90°. That is, the angle between the first end surface 141c and the central axis A of the ink outlet 1201 is less than 90°. When the sealing component 14 is installed in the accommodating space 1202, the inclined surface abuts the inclined surface 121a.

[0077] In one possible embodiment, the abutment surface 121b is perpendicular to the central axis A of the ink outlet 1201, and the end surface of the third section 143 away from the second section 142 is the second end surface 145. When the sealing component 14 is installed in the accommodating space 1202, the second end surface 145 abuts against the abutment surface 121b.

[0078] As shown in Figure 7, the end face of the second end of the accommodating space 1202 protrudes from the inner circumferential surface 121c of the accommodating space 1202 toward the central axis A of the vertical ink outlet 1201, and is formed with abutment surface 121b, that is, a step-like structure is formed at the connection position between the first part 121 and the second part 122, and the abutment surface 121b is the end face of the step-like structure facing the ink outlet 1201.

[0079] In one possible embodiment, the outer circumferential wall of the second section 142 and / or the third section 143 is provided with a rib that abuts the inner circumferential surface 121c of the accommodating space 1202. With this arrangement, when the sealing component 14 is installed in the accommodating space 1202, the rib abuts the inner circumferential surface 121c of the accommodating space 1202. This arrangement can increase the friction between the sealing component 14 and the inner circumferential surface 121c of the accommodating space 1202, thereby preventing the sealing component 14 from moving up and down along the central axis A of the ink outlet 1201.

[0080] The sealing component 14 is provided with at least one convex rib.

[0081] The sealing component 14 may be provided with a rib abutting the inner circumferential surface 121c of the accommodating space 1202 only on the outer circumferential wall of the second section 142, and the third section 143 may not have a rib. Specifically, the outer circumferential wall of the second section 142 may be provided with a first rib 142a abutting the inner circumferential surface 121c of the accommodating space 1202; or, the sealing component 14 may be provided with a rib abutting the inner circumferential surface 121c of the accommodating space 1202 only on the outer circumferential wall of the third section 143, and the second section 142 may not have a rib. Specifically, the outer circumferential wall of the third section 143 may be provided with a A second convex rib 143a abutting against the inner circumferential surface 121c of the accommodating space 1202; or, as shown in Figure 10, the sealing component 14 can be provided with convex ribs abutting against the inner circumferential surface 121c of the accommodating space 1202 on the outer circumferential walls of the second section 142 and the third section 143. Specifically, the outer circumferential wall of the second section 142 can be provided with a first convex rib 142a abutting against the inner circumferential surface 121c of the accommodating space 1202, and the outer circumferential wall of the third section 143 can be provided with a second convex rib 143a abutting against the inner circumferential surface 121c of the accommodating space 1202.

[0082] Multiple layers of first ribs 142a may be provided on the outer peripheral wall of the second section 142 along the axial direction of the ink outlet 1201. The first ribs 142a may be complete annular ribs or multiple short ribs on the same circumference.

[0083] Multiple layers of second ribs 143a may be provided on the outer peripheral wall of the third section 143 along the axial direction of the ink outlet 1201. The second ribs 143a may be complete annular ribs or multiple short ribs on the same circumference.

[0084] In a possible embodiment, as shown in Figure 5, observing the bottle mouth piece 12 from the outside, the bottle mouth piece 12 includes a first part 121, a second part 122 and a third part 123, the first part 121 is arranged away from the bottle body piece 11, the ink outlet 1201 is located on the first part 121, the third part 123 is arranged close to the bottle body piece 11, the second part 122 is located between the first part 121 and the third part 123, the inner diameter of the second part 122 is less than or equal to the inner diameter of the first part 121, and when the ink bottle 10 is connected to the ink tank 20, the inner circumferential surface 121c on the second part 122 abuts against the side walls of the ink supply needle 23 in each radial direction.

[0085] A receiving space 1202 is provided in the first portion 121 of the bottle mouth 12 near the ink outlet 1201 .

[0086] The third portion 123 has an external thread 123 a on its outer peripheral wall.

[0087] The sealing component 14 is installed in the first portion 121. As shown in Figures 9 and 10, the sealing component 14 further includes a valve plate 144. The valve plate 144 is provided on the inner side wall of the third section 143 at one end away from the second section 142.

[0088] The valve plate 144 is provided with a self-closing notch (not shown in the figure). The self-closing notch can be in a closed state due to its own elasticity, so that the sealing component 14 can seal the ink outlet 1201. Specifically, the self-closing notch can be a straight notch, a cross notch, or a Pozigzag notch. In the absence of external force, the self-closing notch can be in a closed state due to its own elasticity, so that the sealing component 14 can seal the ink outlet 1201.

[0089] For example, as shown in Figures 7 and 9, the inner diameter of the second part 122 of the bottle mouth piece 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, and a protrusion 141a is also provided on the inner side wall of the sealing component 14. The protrusion 141a is farther away from the second part 122 than the valve plate 144, that is, the protrusion 141a is provided close to the ink outlet 1201, but its position is lower than the ink outlet 1201.

[0090] Optionally, as shown in FIG9 , there are at least two protrusions 141 a, with air passages 141 b disposed between adjacent protrusions 141 a. When the ink bottle 10 is connected to the ink tank 20, the interior of the second portion 122 abuts the ink supply needle 23 in any radial direction. Simultaneously, the protrusions 141 a abut the outer peripheral wall of the ink supply needle 23, allowing external air to enter the bottle through the air passages 141 b. This arrangement stabilizes the ink bottle 10 and the ink tank 20, preventing the ink bottle 10 from tilting. Furthermore, it accelerates ink filling, ensuring effective ink filling. Alternatively, the protrusions 141 a may be a ring-shaped protrusion with a notch, which serves as the air passage 141 b. Alternatively, multiple notches may be provided.

[0091] In addition, when the ink supply needle 23 passes through the self-closing incision of the valve plate 144 of the sealing component 14, part of the valve plate 144 will abut against the inner circumferential surface 121c on the second part 122 under the pressure of the ink supply needle 23, thereby positioning the ink bottle 10.

[0092] Furthermore, the ink supply needle 23 can indirectly abut the inner circumferential wall of the second part 122 through the valve plate 144. Specifically, the valve plate 144 has a thickness in the axial direction in the closed state. When the ink supply needle 23 passes through the self-closing incision, the valve plate 144 will be squeezed open and wrapped around the outer circumferential 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 squeezed 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 the valve plate 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 circumferential surface 121c on the second part 122 (or indirectly abuts against the inner circumferential surface 121c on the second part 122 through the valve plate 144 of the sealing component 14), which can position the ink bottle 10 in the connected state. Without setting any other positioning part or locking part, the ink bottle 10 can be tightly locked with the ink tank 20, and the connection is stable to prevent ink leakage.

[0093] Optionally, since the valve plate 144 is elastic, it can be squeezed by the ink supply needle 23 and the second part 122, that is, it can be compressed and sandwiched between the two. When the valve plate 144 is compressed, its thickness will become smaller, that is, the inner diameter of the second part 122 can be smaller 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 14.

[0094] In one possible embodiment, as shown in Figures 2, 3, and 11 to 13, the ink bottle 10 further includes a bottle cap 13 having an opening at one end and being sleeved onto the bottle mouth piece 12 through the opening. Specifically, the bottle cap 13 is detachably mounted on the bottle mouth piece 12, and an inner peripheral wall 132 of the bottle cap 13 has an internal thread 132a that mates with the external thread 123a of the bottle mouth piece 12 (disposed on the outer peripheral wall of the third portion 123). When the bottle cap 13 is mounted on the bottle mouth piece 12, at least a portion of the bottle cap 13 abuts against the sealing component 14 to ensure a seal between the sealing component 14 and the ink outlet. The bottle cap 13 has a top portion 131 and a bottom portion 133 connected to the inner circumferential wall 132. The bottom portion 133 is one end of the bottle cap 13 opening, and the top portion 131 is the other end opposite to the bottom portion 133. A protrusion 1311 extending toward the bottom end 133 is provided in the middle position of the top portion 131. The protrusion 1311 has an outer circumferential surface 1311a. When the bottle cap 13 is connected to the bottle mouth piece 12, the protrusion 1311 is at least partially inserted into the space of the sealing component 14 and is in interference contact with the inner circumferential wall of the sealing component 14, but will not penetrate into the valve plate 144, so that the sealing component 14 can better seal the ink outlet and ensure a stable seal between the bottle cap 13 and the bottle mouth piece 12.

[0095] As shown in Figures 11 to 13, the bottom end portion 133 has an abutting end surface 133a, and a plurality of teeth 134 are spaced apart on the inner peripheral wall near the bottom end portion 133. The teeth 134 have an end surface 134a parallel to the abutting end surface 133a. The teeth 134 are used to support the bottom end portion 133 of the bottle cap 13 to prevent deformation.

[0096] As shown in Figures 11 to 13, when the bottle cap 13 is connected to the bottle mouth piece 12, the internal thread 132a of the bottle cap 13 is threadedly connected to the external thread 123a on the bottle mouth piece 12, and the bottom end portion 133 of the bottle cap 13 abuts against the abutting portion 114 on the bottle body piece 11, that is, the abutting end surface 133a on the bottom end portion 133 at least partially abuts against the end surface on the abutting portion 114, so that the bottle cap 13 can stably abut against the bottle body piece 11; at the same time, the protrusion 1311 on the top end portion 131 of the bottle cap 13 is inserted into the space of the sealing component 14, and at least a portion of the outer peripheral surface 1311a of the protrusion 1311 abuts and seals against the inner peripheral wall of the sealing component 14 to prevent ink from flowing out of the ink outlet.

[0097] When using the ink bottle 10 of this embodiment to replenish ink into the ink tank 20, the ink bottle 10 is turned upside down and then moved toward the ink inlet 22. The ink supply needle 23 on the ink tank 20 passes through the ink outlet 1201 and the self-closing incision on the sealing component 14 and is connected to the ink cavity 110 of the bottle body 11. The valve plate 144 is squeezed open and wraps around the ink supply needle 23. The ink supply needle 23 abuts against the inner circumferential surface 121c on the second part 122 through the valve plate 144 to form a stable connection. The ink in the ink cavity 110 is replenished into the ink storage cavity 21 of the ink tank 20 through the ink supply needle 23.
