Description

Background Art

[0001] Imaging systems such as printers, copiers, etc. can generate text, images, or objects on a print medium (e.g., paper, plastic, build material bed in the case of three-dimensional (3D) printing, etc.). In some examples, the imaging system can perform a printing job that includes printing text and / or graphics by transferring a printing substance (e.g., ink, toner, adhesive, etc.) to the print medium.

[0009] Printing substance containers, devices, and systems are described herein. For example, in some examples, the printing substance container can hold a printing substance for use in various imaging systems such as printers, etc. In some examples, the printing substance container can include an opening to allow air to be discharged from the printing substance container.

[0010] However, some printing substance containers include a passage for discharging air from the printing substance container. A printing substance container that includes only a limited number of passages for discharging air from the container may have no alternative way to discharge air when the passage is blocked. Thus, negative pressure and / or positive pressure may be formed in the container and cause the printing substance to leak from the container. In addition, some printing substance containers increase the volume of the printing substance container to absorb the spilled printing substance. However, increasing the volume of the printing substance container may increase the cost of manufacturing the container, increase the materials used to manufacture the container, and may still result in leakage due to negative pressure and / or positive pressure if the exhaust passage is blocked.

[0011] However, the printing material container described herein is structurally compact and includes multiple exhaust channels to ensure that air can be discharged from the printing material container to prevent leakage. For example, the printing material container may include an opening to allow air to enter and exit the printing material container. In some examples, a barrier film may cover the opening to prevent the printing material from leaving the printing material container via the opening. When the printing material is in the printing material container, an isolation region of the printing material container can hold the printing material. The printing material container may include multiple exhaust channels to allow air inside the printing material container to be discharged from the opening when the printing material container is in different orientations.

[0012] If air is not properly discharged from the container, a negative pressure and / or a positive pressure may form in the container. The accumulation of the negative pressure and / or the positive pressure may cause the printing material to leak from the container. Accordingly, the present embodiment describes a printing material container including multiple exhaust channels to allow air to be discharged from the printing material container when the orientation of the printing material container changes.

[0013] Figure 1 An example apparatus including a printing material container 102 is shown. For example, the apparatus may be implemented in various imaging systems (such as printers, copiers, etc.). In some examples, the printing material container 102 includes an isolation region 108 to hold the printing material. The isolation region 108 together with other elements of the printing material container 102 ensures that the printing material remains in the printing material container 102 when the printing material container 102 is moved (e.g., the orientation of the printing material container changes). For example, the apparatus includes multiple exhaust channels 104-1, 104-2, 104-3, 104-4 (the exhaust channels 104-1, 104-2, 104-3, 104-4 may be collectively referred to as the exhaust channels 104) to allow air to leave the printing material container 102 and keep the printing material contained in a specific region of the printing material container 102 (e.g., the isolation region 108). For example, the apparatus may include a primary exhaust channel 104-1, a secondary exhaust channel 104-2, and tertiary exhaust channels 104-3, 104-4. As used herein, an "exhaust channel" refers to a route, path, or trajectory along which air, gas, and / or liquid moves.

[0014] In some examples, when the printing material container 102 is in different orientations, multiple exhaust channels allow air to be discharged from the opening. That is, when the orientation of the printing material container 102 is changed, the multiple exhaust channels 104 prevent the printing material from leaking out of the printing material container 102 by allowing air to be discharged from the printing material container 102. In other words, the multiple exhaust channels 104 confine the printing material within the isolation region 108. As used herein, a "printing material container" refers to a container, bottle, bag, box, case, housing, or other suitable vessel adapted to transfer and / or contain printing material. As used herein, "confine" refers to the act of keeping or restricting an object within a certain spatial range.

[0015] In some examples, the use of multiple exhaust channels 104 ensures that air can be discharged through the opening 106 even if another exhaust channel 104 is blocked. Thus, when other exhaust channels are blocked, the printing material will remain in the printing material container 102 because air is discharged through one exhaust channel. As used herein, "printing material" refers to ink, toner, adhesive, etc. used to print text and / or graphics on a printing medium. As used herein, a "printing medium" refers to multiple sheets of paper, photosensitive polymers, plastics, composite materials, metals, wood, or other materials on which marks can be formed.

[0016] In some examples, air enters through a primary inlet 114-1, a secondary inlet 114-2, and a tertiary inlet 114-3 (the inlets 114-1, 114-2, 114-3 may be collectively referred to as the inlet 114) and flows along the exhaust channel 104. In some examples, the inlet 114 may be unblocked. That is, there may be no obstacle restricting access to the exhaust passage 104. However, the present disclosure is not limited to this. In some examples, there may be an obstruction 115 blocking the passage to the exhaust passage 104. The obstruction 115 can limit the material that can enter the exhaust passage 104. For example, the secondary inlet 114-2 has an obstruction 115 blocking the secondary inlet 114-2. The obstruction 115 limits the amount of material entering through the secondary inlet 114-2. The obstruction 115 may allow air to pass through the secondary inlet 114-2 but prevent the printing material from entering. The air in the printing material container 102 can be discharged through the opening 106. That is, each exhaust channel 104-1, 104-2, 104-3, 104-4 leads to the opening 106. The opening 106 allows air to enter and exit the printing material container 102. In some examples, leading the exhaust channel 104 to the opening 106 allows the air trapped in the printing material container 102 to escape from the printing material container 102 while the printing material remains in the isolation region 108 of the printing material container.

[0017] In some examples, the opening 106 is located on the lid 112 of the print material container 102. The opening 106 can be individually connected to each of the exhaust channels 104-1, 104-2, 104-3, 104-4 to allow air to escape through the opening 106. In some examples, as Figure 1 shown, the exhaust channel 104-3 can share a portion of the passage with another exhaust channel 104-4. However, the present disclosure is not limited thereto. For example, each of the exhaust channels 104-1, 104-2, 104-3, 104-4 can have a different and independent passage leading to the opening 106 of the print material container 102. For example, the passage (e.g., the tertiary exhaust channel 104-3) can pass through the bottom of the print material container 102 and through the first side 111 of the print material container 102 towards the lid 112 of the print material container 102 to the opening 106. In some examples, the passage (e.g., the secondary exhaust channel 104-2) can start near the second side 113 and lead to the opening 106 along the top of the print material container 102 (e.g., near the lid 112). In various examples, the passage (e.g., the exhaust channel 104-1) can lead from the isolation region 108 to the opening 106. Additionally, the passage (e.g., the exhaust channel 104-4) can be connected to another passage (e.g., the tertiary exhaust channel 104-3) and lead to the opening 106 from the connected passage.

[0018] Figure 1 The print material container 102 is shown in a first orientation. In some examples, the first orientation is a position where the side directly opposite the lid 112 is parallel to the ground. For example, when the print material container 102 is in the first orientation, if there is print material in the print material container 102, gravity will force the print material towards the side directly opposite the lid 112 of the print material container 102. That is, when the print material container is in the first orientation, the side directly opposite the lid 112 will be regarded as the bottom surface.

[0019] In the first orientation, when gravity pulls the print material towards the side directly opposite the lid 112, the primary inlet 114-1 remains open and unblocked. Similarly, the primary exhaust channel 104-1 also remains open and is not blocked by the print material in the print material container 102. Thus, air can escape through the unblocked opening 106, preventing the leakage of print material. In the first orientation, the primary exhaust channel 104-1 helps to keep the opening 106 isolated from the print material. That is, although other exhaust channels (e.g., exhaust channels other than the primary exhaust channel 104-1) may be blocked, the unblocked primary exhaust channel 104-1 ensures that air has a path to escape from the print material container 102. Therefore, the print material can be retained within the isolation region 108.

[0020] Setting a plurality of exhaust channels 104 in the printing material container 102 can prevent the leakage of the printing material when the posture of the printing material container 102 changes. That is, when the orientation of the printing material container 102 changes, air can still be discharged through one or more exhaust channels 104. Setting a plurality of exhaust channels 104 can ensure that air can be discharged from the printing material container 102 and ensure that there is no negative pressure or positive pressure in the printing material container 102. Negative pressure or positive pressure may cause the leakage of the printing material. In other words, ensuring that there is a channel for discharging air from the printing material container 102 can prevent the leakage of the printing material.

[0021] Figure 2 An example system 200 including a printing material container 202 is shown. Figure 2 May include elements similar or analogous to Figure 1 For example, Figure 2 May include an opening 206, a printing material container 202, and / or a lid 212.

[0022] In some examples, the lid 212 of the printing material container 202 may include a barrier film 210 disposed inside the printing material container 202. The barrier film 210 may be directly disposed below the opening 206. In some examples, the barrier film 210 may cover the opening 206 to prevent the printing material from leaving the printing material container 202. Conversely, the barrier film 210 allows air to be discharged from the printing material container 202. The barrier film 210 can be used to restrict the material escaping through the opening 206. For example, the barrier film 210 can prevent the printing material from leaking from the printing material container 202 via the opening 206. However, conversely, the barrier film 210 can allow air to be discharged through the opening 206. In other words, the barrier film 210 is impermeable to the printing material but permeable to air. The exhaust channels (e.g., Figure 1 the exhaust channels 104-1, 104-2, 104-3, and 104-4 in

[0023] In some examples, the barrier film 210 can be made of polypropylene or polyethylene material. For example, the barrier film 210 can be a polypropylene-based material for blocking the opening 206 to prevent the printing material from leaking from the opening 206 of the printing material container 202. Additionally, the barrier film 210 can be made of a polyethylene-based material for restricting the escape of a specific material in the printing material container 202. In some examples, the barrier film 210 can be a laminated flexible thin sealing film that is permeable to air but impermeable to the printing material. In other words, the barrier film 210 can be a vapor / oxygen barrier film that allows gas to escape from the printing material container 202. The barrier film 210 can cover the opening 206 inside the printing material container 202 to allow gas to escape from the printing material container 202 and prevent the printing material from leaking through the opening 206.

[0024] Figure 3A An example printing material container 302 in a specific orientation is shown. Figure 3A can include elements similar or like Figure 1 and Figure 2 For example, Figure 3A can include a system 300 that includes an opening 306, a printing material container 302, a tertiary exhaust passage 304-3, a tertiary inlet 314-3, an isolation region 308, a barrier film 310, and / or a cap 312.

[0025] Figure 3A The printing material container 302 in a second orientation is shown. In some examples, the second orientation is a configuration where the cap 312 is parallel to the ground. For example, when the printing material container 302 is in the second orientation, if there is printing material in the printing material container 302, gravity will force the printing material towards the cap 312 of the printing material container 302. That is, when the printing material container is in the second orientation, the cap 312 will be temporarily (e.g., when in the second orientation) regarded as the bottom surface.

[0026] In the second orientation, when gravity pulls the printing material towards the cap 312, the tertiary inlet 314-3 remains open and unblocked. Similarly, the tertiary exhaust passage 304-3 remains open and is not blocked by the printing material in the printing material container 302. When the printing material container 302 is in the second orientation, air can still escape from the printing material container 302. For example, air can escape from the isolation region 308 through the tertiary inlet 314-3, travel through the tertiary exhaust passage 304-3 to reach the barrier film 310, and then reach the opening 306. Thus, the printing material in the printing material container 302 remains in the isolation region 308 and does not leak from the printing material container 302.

[0027] As described herein, a print material container 302 including a plurality of exhaust channels 304 can ensure that a portion of the barrier film 310 and the opening 306 are isolated from the print material. Isolating the print material from a portion of the barrier film 310 and the opening 306 can ensure that air can be exhausted from the print material container 302. That is, other exhaust channels (e.g., exhaust channels other than the tertiary exhaust channel 304-3) are blocked by the print material and air cannot be exhausted through the blocked exhaust channels. In addition, in a second orientation, the print material may block the passage in other exhaust channels (e.g., exhaust channels other than the tertiary exhaust channel 304-3). However, even if other exhaust channels (e.g., exhaust channels other than the tertiary exhaust channel 304-3) are blocked by the print material, the tertiary exhaust channel 304-3 remains unblocked in the second orientation. In addition, the tertiary inlet 314-3 connected to the tertiary exhaust channel 304-3 also remains unblocked in the second orientation. Therefore, air can be exhausted from the print material container 302.

[0028] Figure 3B An example print material container 302 in a particular orientation is shown. Figure 3B may include elements similar or analogous to Figure 1 , 2 and 3A. For example, Figure 3B may include a system 300 that includes an opening 306, a print material container 302, a secondary exhaust channel 304-2, a secondary inlet 314-2, an isolation region 308, a barrier film 310, a first side 311, and / or a lid 312.

[0029] Figure 3B The print material container 302 in a third orientation is shown. In some examples, the third orientation is a configuration in which the first side 311 of the print material container 302 is parallel to the ground. For example, when the print material container 302 is in the third orientation, if there is print material in the print material container 302, gravity will force the print material toward the first side 311 of the print material container 302. That is, when the print material container is in the third orientation, the first side 311 will be temporarily (e.g., when in the third orientation) regarded as the bottom surface.

[0030] In the third orientation, when gravity pulls the printing material towards the first side 311, the secondary inlet 314-2 remains open and unblocked. Similarly, the secondary exhaust passage 304-2 remains open and is not blocked by the printing material in the printing material container 302. When the printing material container 302 is in the third orientation, air can still be discharged from the printing material container 302. For example, air can escape from the isolation region 308 through the secondary inlet 314-2, travel through the secondary exhaust passage 304-2 to the barrier film 310, and then reach the opening 306. Keeping at least one unblocked exhaust passage 304 can prevent the printing material from escaping from the printing material container and ensure that the printing material in the printing material container 302 remains in the isolation region 308.

[0031] In some examples, in the third orientation, the secondary exhaust passage 304-2 ensures that a portion of the barrier film 310 and the opening 306 are isolated from the printing material to allow air to flow through the opening 306 and the barrier film 310. In the third orientation, the printing material may block the passageways and the barrier film 310 connected to other exhaust passages (e.g., exhaust passages other than the secondary exhaust passage 304-2). However, even if other exhaust passages (e.g., exhaust passages other than the secondary exhaust passage 304-2) and the barrier film 310 connected to other exhaust passages (e.g., exhaust passages other than the secondary exhaust passage 304-2) are blocked by the printing material, the secondary exhaust passage 304-2 and the portion of the barrier film 310 connected to the secondary exhaust passage 304-2 remain unblocked in the third orientation. In addition, the secondary inlet 314-2 connected to the secondary exhaust passage 304-2 also remains unblocked in the third orientation. Therefore, air can be discharged from the printing material container 302.

[0032] Figure 3C An example printing material container 302 in a specific orientation is shown. Figure 3C May include elements similar or analogous to Figure 1 、 2 、3A and 3B. For example, Figure 3C May include a system 300, the system 300 including an opening 306, a printing material container 302, a primary exhaust passage 304-1, an isolation region 308, a barrier film 310, a second side 313, and / or a lid 312.

[0033] Figure 3CShows the print material container 302 in a fourth orientation. In some examples, the fourth orientation is a configuration in which the second side 313 of the print material container 302 is parallel to the ground. For example, when the print material container 302 is in the fourth orientation, if there is print material in the print material container 302, gravity will force the print material towards the second side 313 of the print material container 302. That is, when the print material container is in the fourth orientation, the second side 313 will be temporarily (e.g., when in the fourth orientation) regarded as the bottom surface.

[0034] In the fourth orientation, when gravity pulls the print material towards the second side 313, the primary inlet 314-1 remains open and unblocked. Similarly, the primary exhaust passage 304-1 also remains open and is not blocked by the print material in the print material container 302. When the print material container 302 is in the fourth orientation, air can still be discharged from the print material container 302 through the primary exhaust passage 304-1. For example, air can escape from the isolation region 308 through the primary inlet 314-1, travel through the primary exhaust passage 304-1, and reach the barrier film 310 and the opening 306 connected to the primary exhaust passage 304-1. In some examples, when in the fourth orientation, the primary exhaust passage 304-1 helps the print container 302 prevent print material leakage. Thus, the print material will remain in the isolation region 308.

[0035] In some examples, in the fourth orientation, the primary exhaust passage 304-1 ensures that a portion of the barrier film 310 and the opening 306 are isolated from the print material to allow air to flow through the opening 306 and the barrier film 310. In other words, in the fourth orientation, the print material may block the passageways and the barrier film 310 connected to other exhaust passages (e.g., exhaust passages other than the primary exhaust passage 304-1). However, even if other exhaust passages (e.g., exhaust passages other than the primary exhaust passage 304-1) and the barrier film 310 connected to other exhaust passages (e.g., exhaust passages other than the primary exhaust passage 304-1) are blocked by the print material, the primary exhaust passage 304-1 and the connected components remain unblocked in the fourth orientation. Specifically, the barrier film 310 and the primary inlet 314-1 connected to the primary exhaust passage 304-1 are not blocked by the print material. Setting the primary exhaust passage 304-1 and the primary inlet 314-1 connected to the primary exhaust passage 304-1 to be unblocked allows air to be discharged from the print material container 302.

[0036] Figure 3D Shows an example print material container 302 in a specific orientation. Figure 3D May include elements similar or analogous to Figure 1 、 2 、3A, 3B, and 3C. For example, Figure 3Dmay include system 300, which includes opening 306, printing material container 302, secondary exhaust passage 304-2, secondary inlet 314-2, isolation region 308, barrier film 310, and / or lid 312.

[0037] Figure 3D The printing material container 302 in the fifth orientation is shown. In some examples, the fifth orientation is a configuration in which the back side 317 of the printing material container 302 is parallel to the ground. For example, when the printing material container 302 is in the fifth orientation, if there is printing material in the printing material container 302, gravity will force the printing material towards the back side 317 of the printing material container 302. That is, when the printing material container is in the fifth orientation, the back side 317 will be temporarily (e.g., when in the fifth orientation) regarded as the bottom surface.

[0038] In the fifth orientation, when gravity pulls the printing material towards the back side 317, the secondary inlet 314-2 remains open and unblocked. Similarly, the secondary exhaust passage 304-2 also remains open and is not blocked by the printing material in the printing material container 302. When the printing material container 302 is in the fifth orientation, air can still be discharged from the printing material container 302. For example, air can escape from the isolation region 308 through the secondary inlet 314-2, travel through the secondary exhaust passage 304-2 to the barrier film 310, and then to the opening 306.

[0039] In some examples, in the fifth orientation, air can flow through the barrier film 310 and the opening 306 connected to the secondary exhaust passage 304-2. That is, in the fifth orientation, the barrier film 310 and the opening 306 connected to the secondary exhaust passage 304-2 are not covered by the printing material. Therefore, setting the opening 306 and the barrier film 310 to be connected to the secondary exhaust passage 304-2 can prevent the accumulation of negative or positive pressure, especially when the exhaust passage is blocked (e.g., exhaust passages other than the secondary exhaust passage 304-2). For example, in the fifth orientation, the printing material may block the passageway and the barrier film 310 connected to other exhaust passages (e.g., exhaust passages other than the secondary exhaust passage 304-2). However, even if other exhaust passages (e.g., exhaust passages other than the secondary exhaust passage 304-2) and the barrier film 310 connected to other exhaust passages (e.g., exhaust passages other than the secondary exhaust passage 304-2) are blocked by the printing material, the secondary exhaust passage 304-2 remains unblocked in the fifth orientation. In addition, the secondary inlet 314-2 connected to the secondary exhaust passage 304-2 also remains unblocked in the fifth orientation.

[0040] Figure 3E An example printing material container 302 in a specific orientation is shown. Figure 3E may include associated with Figure 1 、2 Elements similar or analogous to 3A, 3B, 3C, and 3D. For example, Figure 3E It may include system 300, which includes opening 306, printing material container 302, tertiary exhaust passage 304-3, isolation region 308, barrier film 310, and / or lid 312.

[0041] Figure 3E The printing material container 302 in the sixth orientation is shown. In some examples, the sixth orientation is a position where the front side 319 of the printing material container 302 (e.g., the side directly opposite to the Figure 3D rear side 317 described therein) is parallel to the ground. For example, when the printing material container 302 is in the sixth orientation, if there is printing material in the printing material container 302, gravity will force the printing material towards the front side 319 of the printing material container 302. That is, when the printing material container is in the sixth orientation, the front side 319 will be temporarily (e.g., when in the sixth orientation) regarded as the bottom surface.

[0042] In the sixth orientation, when gravity pulls the printing material towards the front side 319, the tertiary inlet 314-3 remains open and unblocked. Similarly, the tertiary exhaust passage 304-3 also remains open and is not blocked by the printing material in the printing material container 302. When the printing material container 302 is in the sixth orientation, air can still be discharged from the printing material container 302. When the tertiary exhaust passage 304-3, the barrier film connected to the tertiary exhaust passage 304-3, and the opening connected to the tertiary exhaust passage 304-3 remain unblocked, the examples described herein can hold the printing material in the isolation region 308 and prevent the printing material from leaking from the printing material container 302.

[0043] In some examples, in the sixth orientation, the tertiary exhaust passage 304-3 ensures that the opening 306 and a portion of the barrier film 310 are not blocked by the printing material to allow air to flow through the opening 306 and the barrier film 310. In the sixth orientation, the printing material may block the passageways and the barrier film 310 connected to other exhaust passages (e.g., exhaust passages other than the tertiary exhaust passage 304-3). However, even if other exhaust passages (e.g., exhaust passages other than the tertiary exhaust passage 304-3) and the barrier film 310 connected to other exhaust passages (e.g., exhaust passages other than the tertiary exhaust passage 304-3) are blocked by the printing material, the tertiary exhaust passage 304-3 remains unblocked in the sixth orientation. In addition, the tertiary inlet 314-3 connected to the tertiary exhaust passage 304-3 also remains unblocked in the sixth orientation.
