INSTRUCTIONS: I: TECHNICAL FIELD OF THE INVENTION The present invention relates to a technique for filling an ink pen. 5 [Prior Art] Background of the Invention It is sometimes desirable to deliver different volumes of ink in an inkjet ink pen. Inkjet ink pens are also commonly referred to as ink cartridges. In many conventional ink pens, a piece of foam is used to hold the ink inside the pen and to help create the back pressure required to regulate the flow of ink to the print head. In the case of a special ink pen, the foam block has a fixed size and a maximum ink capacity corresponding to the size of the plastic block. A suitably sized foam block is inserted into the pen body and a desired volume of ink is injected into the foam. Using conventional filling methods, the ink can be properly injected into the foam at any location between the minimum fill volume required to make a functional pen and the maximum capacity of the 15 pieces of foam. When the volume of the ink is much lower than the maximum capacity of the foam block, the foam is clearly not completely filled, resulting in insufficient use of the foam. Although different sizes of foam blocks can be used for different ink fill volumes to more efficiently utilize the foam plastic, it is necessary to specially trim each of the 20 different sizes of foam plastic blocks to insert the foam into the pen body. In addition, the pen body may have to be redesigned to properly retain foam blocks of different sizes. Therefore, the use of different sizes of foam blocks may result in multiple pen body designs and trims that are not interchangeable in real time, and may still leave unused foam in the design of some pens. 200918345 SUMMARY OF THE INVENTION Summary of the Invention In order to more effectively utilize different ink filling volumes in an ink pen, embodiments of the present disclosure have been developed. In the following embodiments, a fifth, more sensitive material, such as a small bubble plastic block, is placed in the body of the pen to cover the outlet from the ink containment chamber to the print head. Then, a second less sensitive material, such as a yarn or a shredded foam, impregnated with ink is placed in the body of the pen until the desired volume of ink is obtained. The higher density material covering the exit produces sufficient capillary action to wick the ink 10 to the exit, while the ink impregnated with the fill material helps to more efficiently use the different ink fill volumes in the ink pen. Illustrative embodiments of the invention are shown and described, but are not intended to limit the disclosure. Other forms, details, and embodiments can be made and implemented. Therefore, the description should not be construed as limiting the scope of the disclosure, which is defined by the scope of the appended claims.

Embodiment 3 Detailed Description of Preferred Embodiments Fig. 1 is an enlarged perspective view showing an ink pen ίο according to an embodiment of the present invention. Fig. 2 is a front cross-sectional view along the side of the first line 2-2. Referring to Figures 1 and 2, the ink pen 10 includes a row of print heads 12 located below the ink receiving chamber 14 at the bottom of the pen 10. The print head 12 includes an orifice disk 16 having two arrays 18, 20 of ink ejection orifices 22. In the embodiment shown, each array 18, 20 15 is a single column of apertures 22. A starter resistor formed in the thermal printer 10 of the integrated circuit chip (not shown) or an ink injector of the other type of ink jet printer 10 is placed behind the ink ejection orifice 22. The flex circuit 24 carries electrical traces from the external contact pads 26 to the ink injectors. When the ink pen 10 is placed in the printer, the pen 10 is electrically connected to the printer controller through the contact pads 26. 20 In operation, the printer controller selectively energizes the ink emitter with the signal traces in the flex circuit 24 to eject ink droplets through the aperture 22 to the print medium. Ink flows from the ink containing chamber 14 through the outlet 28 to the print head 12. The ink chamber 14 is generally defined by a pen body 200918345 30 that includes a front wall 32, side walls 34, a back wall 36 and a bottom plate 38. The print head 12 is placed below the exit 28 in the front recess 40 of the bottom plate 38. The pen body 30, which is typically molded plastic, can be molded into a single unitary 'mold two parts (eg, a lid 42 and a bottom 44) or any number of separate portions that are fastened to each other. Construct the desired configuration. A filter 46 covering the outlet 5 can be used to prevent influx of contaminants, bubbles and ink into the print head 12. A small foam block 48 or other suitable denser, absorbable ink retaining material covers the outlet 28. A less sensitive, absorbable ink retaining material 50, such as a yarn or shredded foam, fills the remainder of some or all of the cavities 14 10 to the desired volume of ink. The higher density of material 42 covering the outlet 28 produces sufficient capillary action to cause the ink to move toward the outlet 28 via capillary action, while the less dense material 5〇 helps to more efficiently use the different ink fill volumes in the cavity 14. . As the ink is replenished from the foam, the increased capillary action near the outlet 28 tends to draw ink from the material 5 to maximize the amount of ink drawn from the chamber 14. Although a single color pen 10 having only one ink chamber 14 is shown and described, the disclosed embodiments are also applicable to two-color and other multi-chamber pens in which a composite ink retaining material can be used in more than one ink chamber. Configuration. 3A-3E shows an embodiment of a method 20 of filling a pen having a varying ink volume. In Figure 3A, a small piece of foam 48 is placed into the ink chamber 14 above the filter 46 and outlet 28. In Fig. 3B, ink is introduced into the foam 48 by, for example, injecting ink into the foam 48 with a needle 52. In Fig. 3C, the pen 1 is filled with ink by forcing ink through the aperture 22 into the print head 12. Filling used in this document 200918345 Ink pen ίο means removing sufficient air from the ink delivery zone, nozzles and/or other areas of the printhead 12 so that any remaining bubbles do not degrade the print quality. Figure 3C shows only one method of loading the pen 1〇. Any suitable method for filling the pen 1 can also be used. For example, a low pressure can be applied to the orifice plate 16 to draw ink from the bead plastic 28 into the print head 12. In Figure 3D, an ink absorbing yarn 5 is dispersed into the ink chamber 14 from a spool 54 or other suitable dispersing unit. One of the benefits of this new filling method is that the ink retaining material can be pre-impregnated with ink (in this embodiment, the yarn 5 〇> with the ink pre-impregnated yarn 5 〇 helps to ensure that the entire ink of the ink in the chamber 14 is 1 〇 Maintaining a uniform distribution within the material helps to avoid undesired zones of free ink gelation in the amine 14 and helps control the volume of ink held in the cavity 14. Figure 3D generally shows how the pre-impregnated yarn 5〇 The bobbin 5 4 immersed in the ink reservoir 56 as part of the dispersing unit 58 is scattered into the cavity 14. Although it is expected that in most of the filling methods, the continuous reduction of the medium of the length of 15 money, such as (4) , would be desirable, "any suitable dispersion can be made. Another part of this new filling method is not only the amount of ink holding material that can be dispersed into the cavity, but also the ink holding material in the cavity 14 For example, the directional arrows 6 〇 and 62 represent the actuation or swing of the pen body 30 relative to the yarn 50 (or the yarn 50 2 〇 relative to the pen body 3 〇) in the disperser 58. By controlling the pen body 30 and yarn 50: relative movement 'in the ink chamber 14 A variety of yarn laminate patterns are created: by controlling the image of the alternating yarns from substantially vertical to substantially parallel, it is possible to achieve different yarn densities and holes, and corresponding capillary action. 200918345 Finally, In Fig. 3E, the cover 42 is attached to the pen body 3〇 to complete the filling of the pen 1〇. The above method embodiment of the Macquarie 3A-3E diagram is illustrated in the flow chart of Fig. 4. Referring to Fig. 4, 'in-ink In the filling method 64, a denser ink retaining material, the foam block 48 of Figs. 3A-3E, is placed above the ink outlet 28 in the ink chamber 14 (block 66). The ink is injected or added. Foam 48 (block 68). Ink pen 10 is filled with ink (block 7〇) and a relatively dense ink retaining material pre-impregnated with ink, and the ink-impregnated yarn 5 4 ' of FIG. 3D is dispersed into In the cavity 14 (block 7 2). The yarn used in this document means 10 natural or man-made fibers of any continuous strand. As previously described in Figure 3D, the yarn 50 is dispersed into the cavity 14 (block 72) The action may include the relative movement of the pen body 3〇 and the yarn 50 to form a pattern and a layer. The desired yarn 5 〇 density and / or hole degree (and corresponding capillary action) and the required ink filling volume. By determining the amount of yarn impregnated by the ink of the dispersion process, from the same 15 yarn goods, Various levels of ink fill are possible. While it is contemplated that the actions in the water fill method 64 will be performed in the order shown in Figure 4, in some cases it may be desirable to change the order of display. For example, By inserting ink into the bead plastic (block 68) and filling the pen 10 (block 70) after the dispersion yarn 50 enters the cavity 14 (block 72), some of the automated processes used in the conventional filling process can be more effective. Used in the embodiment of the new filling process. As another example, the ink is injected into the foam (block 68) simultaneously with the loading pen 1 (block 70). Therefore, the actions shown in Fig. 4 are not implemented in the order shown. 200918345 Figures 5A-5C show an illustration of the dispersion yarn 50 entering the ink chamber 丨4. By controlling the swing of the pen relative to the yarn, or vice versa, controlling the swing of the yarn relative to the pen to change the primary direction of the layer, a variety of densities can be achieved. In Figure 5A, the alternating layers of yarn are substantially perpendicular to each other to cause a lower density of yarn defects in the water chamber 14 of the ink. In Figure 5B, the alternating layers are substantially parallel to one another to create a higher density yarn 50 in the cavity 14 than the vertical pattern of Figure 5A. Fig. 5C shows the yarn of varying density 5 , and, therefore, the corresponding varying hole and capillary action in the yarn 5 。. By controlling the rate of relative movement between the yarn 5〇 and the pen body 3〇, (4) the dispersed yarn% enters the cavity (4), and the higher density yarn 50 can be dispersed into a portion of the ink chamber 14 and the lower density yarn 50 in the other part of the ink chamber 14 towel. This duty gradient forms a corresponding capillary action gradient within the yarn 5〇 in the cavity 14. Figures 6A-6E show another embodiment of a method of filling a pen 1' with a variable volume of ink. In Figure 6A, the thin bubble bead block 74 is placed over the receptacle 46 and outlet 28 in the ink chamber 14 and along the bottom plate of the cavity 14. In the first embodiment, ink is introduced into the bead plastic 74 by ejecting ink into the bead plastic 74, for example, by the needle 52. In Fig. 6C, the pen 1Q is filled with ink by forcing ink through the aperture U into the print head 12. The first _ is displayed by the slogan _ method. Any method known as pen filling can be used. In Figure 6D, the ink absorbing foam sheet % is dispersed into the ink chamber μ from the hopper 78 or other suitable dispersing unit. An advantage of this new method of filling method is that the ink retaining material (the bead plastic sheet 76 in this embodiment) can be pre-impregnated with ink. Pre-impregnated foam sheet with ink %. Helps ensure consistent distribution of ink throughout the ink holding material in the chamber, 11 200918345 Helps avoid unwanted areas of free ink gelation in chamber 14, and helps control be maintained The volume of ink in cavity 14. In this embodiment of the filling method, if desired, by mixing the foamed plastic sheets having different/changing densities and voids, different foam densities and voids can be achieved, and the capillary action of the sheets should be achieved. Finally, in Fig. 6E, the cover 42 is attached to the pen body 30 to complete the filling pen 10. The embodiment of the method described with reference to Figs. 6A-6E is illustrated in the flow chart of Fig. 7. Referring to Fig. 7, in an ink filling method 8A, a denser ink retaining material, the foam block 74 of Figs. 6A-6E, is placed over the ink outlet 28 in the water chamber 14 of the ink 10 and covered. The chamber 14 is seated (block 82). Ink water is injected or raked into the foam 74 (block 84). The ink pen 1〇 is filled with ink (block 86) and a relatively dense ink retaining material pre-impregnated with ink, and the ink-impregnated foam plastic sheet % in the 6D is dispersed into the cavity 14 (square 88). Although it is contemplated that the actions in the ink filling method 8 will be performed in the order shown in Figure 7, in some cases it may be desirable to change the order shown. For example, by adding ink to the foam (block 84) and loading the pen (block 86) after the dispersing foam sheet 76 enters the cavity 14 (block 88), some of the automated processes used in conventional filling processes can be more effective. Used in the embodiment of the new filling process. Another example is that the ink is injected into the foam 2 〇 plastic (block 84) and the filling pen 1 〇 (the squares are called simultaneously. Therefore, the actions shown in Fig. 7 are not necessarily implemented in the order shown. By controlling the dispersion into the cavity The number of &'unplastic sheets 76 in 14 can achieve the desired ink volume maintained in the chamber 10. The individual ink pens 10 can have a certain amount of ink fill determined by the number of foam sheets 76 dispersed into the chamber 14. 12 200918345 Figure 8 shows an embodiment in which the size of the foam sheet 76 is varied to vary the density of the ink retaining material in the chamber 12 and the capillary action characteristics of the corresponding ink retaining material. Referring to Figure 8, the smaller foam The sheet 76a is dispersed into the bottom of the ink chamber 12 to form a more dense, higher capillary action zone 90, 5 and the larger foam sheet 76b is dispersed into the top of the cavity 12 to form a less dense, lower capillary action zone 92. In the example of the ink retaining material, the sizes of the bubble plastic sheets 76a and 76b range from 2 mm to 10 mm.

Other types, details, and embodiments may be made without departing from the spirit and scope of the present disclosure as defined in the following claims. I.
