Description

MULTI-COLOR DRY-ERASE MARKER APPARATUS AND INSERTSCROSS REFERENCE TO RELATED APPLICATION(S)

[0001] This application relates to and claims the benefit of priority from U.S. Provisional Patent Application No. 63 / 667,461, filed on July 3, 2024, the entire disclosure of which is incorporated herein by reference.FIELD OF THE DISCLOSURE

[0002] The present disclosure relates to a multi-color dry erase marker(s) with integrated eraser(s), insert(s) associated therewith, and a method for making and / or using the same.BACKGROUND INFORMATION

[0003] A dry-erase marker is a marking instrument which deposits ink that dries quickly, and can be easily removed from smooth surfaces simply by rubbing away, typically without the need for a liquid cleaning agent. Dry-erase markers were originally invented in the 1970s and have become ubiquitous cognitive tools in classrooms and offices as they are safe, mostly hygienic and easy to use.

[0004] The construction of a dry-erase marker is essentially the same as other types of pens and markers, although an important difference being the type of ink. The ink of such dry-erase marker is a specialized mixture of components that allows the ink to flow out of the marker and create a quick drying, vibrant, and non-permanent color marking on the writing surface. There are a number of components provided for the dry-erase marker ink: a) Pigment (i.e., powder pigment dye that dissolves into the solvent), b) Resin which suspends pigment and makes sure the marker writes smoothly, c) Release agent soluble in solvent but insoluble in resin / pigment mixture, and which facilitates the pigment to be wiped away from board once solvent dries, d) Solvent which dissolves resin / pigment and release agent and makes it flow out pen nib, whereas the solvent in dry erase markers can be commonly isopropanol, and e) Wax which keeps marker from drying out when left uncapped.

[0005] While writing, the ink flows out of the dry-erase marker’s nib onto the writing surface. As the solvent quickly evaporates in air the release agent and pigment / resin mixture areleft behind and quickly separate into two layers. The release agent forms between the writing surface and the pigment, so that the pigment does not strongly bond to the surface. When wiped with a dry eraser, the pigment / resin layer sticks to the eraser leaving behind only the clear release agent on the writing surface.

[0006] The wax portion of the ink serves to coat the dry-erase marker nib when the marker is left uncapped for long periods of time and creates a barrier on the nib preventing solvent evaporation. When the nib is pressed to a writing surface, friction causes the wax to release from the nib and allows ink to flow out of the marker.

[0007] Dry-erase markers are often preferred over other writing options, such as chalk and chalkboards. This is the case for a number of reasons. For example, chalk is brittle and often breaks when used. Chalk also is messy and can end up on a user’s hands and / or clothes, and chalk dust can even end up in a user’s eyes or be inhaled. Moreover, traditional chalk sticks are relatively small, and therefore, do not fit in the hand as well as some dry-erase markers. Further, chalk can provide an uncomfortable tactile feedback for some users. Chalk also is less vibrant on a traditional chalkboard as compared with dry-erase markers on a white dry-erase board. Cleaning is another advantage for dry-erase markers, whereas chalk leaves a cloudy residual after erasing.

[0008] Although being preferrable over other writing options, prior dry-erase markers have drawbacks. For example, in many settings, users have a need for different color dry-erase markers to illustrate differences in diagrams, drawings, graphs, text, etc. This requires a user to have multiple markers, and to continually switch between the different color markers. In practice this can be cumbersome and inefficient. Moreover, erasing can be problematic with prior dry-erase markers. Traditionally, dry-erase boards include a ledge at the bottom where markers and erasers are placed. However, erasers tend to be lost over time. The end result is that a user may not have access to an eraser when needed. The user is then forced to decide between wasting time searching for an eraser or using his or her hand as a substitute eraser.

[0009] Thus, it may be beneficial to provide exemplary methods and apparatuses which can centralize multiple colors and an eraser into a single dry-erase marker, and address at least some of the deficiencies of the prior dry-erase markers.SUMMARY OF EXEMPLARY EMBODIMENTS

Moreover, while the present disclosure will now be described in detail with reference to the figures, it is done so in connection with the illustrative embodiments and is not limited by the particular embodiments illustrated in the figures and the appended claims.DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

[0047] The following description of exemplary embodiments provides non-limiting representative examples referencing numerals to particularly describe features and teachings of different aspects of the present disclosure. The exemplary embodiments described should be recognized as capable of implementation separately, or in combination, with other exemplary embodiments from the description of the exemplary embodiments. A person of ordinary skill in the art reviewing the description of the exemplary embodiments should be able to leam and understand the different described aspects of the present disclosure. The description of the exemplary embodiments should facilitate understanding of the exemplary embodiments of the present disclosure to such an extent that other implementations, not specifically covered but within the knowledge of a person of skill in the art having read the description of embodiments, would be understood to be consistent with an application of the exemplary embodiments of the present disclosure.

[0048] Referring to Fig.. 1, an exemplary embodiment of a dry-erase marker 100 of the present disclosure is depicted. Exemplary dry-erase marker 100 can facilitate deployment(s), extension(s) and / or dispensing of dispense multiple different marker colors from a single device.

[0049] Dry-erase marker 100 can include a plurality of individual marker segments that can have individual or shared housings, which together can form dry-erase marker 100. Each marker segment of dry-erase marker 100 can include a separate aperture 105, 110, 115, 120 at a proximal end thereof. As a result, each color wick or nib from a respective segment can be separately and / or simultaneously extended and / or deployed as shall be further discussed herein.For example, Fig. 1 depicts dry-erase marker 100 with one marker segment activated, resulting in deployed nib 116 extending through aperture 115. The other marker segments are each depicted in a retracted position. Each marker segment can be activated and the corresponding nib deployed by pressing down one of the plunger caps, 125, 130, 135, 140 at a distal end of the marker.

[0050] Dry-erase marker 100 can be fully modular. For example, the colors and configuration of dry-erase marker 100 can be changed by the user. When more than one color is concurrently deployed, dry-erase marker 100 can provide multiple concurrent colors by extending multiple wicks / nibs of the respective segments. The orientation and combination of colors used while writing or drawing can be selected by the user through color deployment (e.g., by pressing a combination of plunger caps 125, 130, 135, 140) and through user selection of which colors to include in dry-erase marker 100, as well as the orientation of those colors within Dry-erase marker 100. Dry-erase marker 100 can be modular in color selection and orientation, as well as in a design of the nibs / wicks. For example, nib 116 depicted in Fig. 1 is a standard fine point, although the user can change the nib to one of any other nib shape such as chisel, super fine, semi-broad, calligraphy, round, brush, etc. Dry-erase marker 100 can be configured with different colors and / or nib shapes. For example, dry-erase marker 100 can be configured with four green sections, all with different nib shapes, four different colors all with the same nib shape, or any combination in-between.

[0051] Deployed nib 116 can be retracted by pressing the corresponding retraction button 145. Each discrete marker segment in dry-erase marker 100 can have its own retraction button.

[0052] Further, detail erasers 150, 155 can be provided proximal to each aperture 105, 110, 115, 120, respective. . The detail eraser 150, 155 can be convenient when writing or drawing with dry-erase marker 100. For example, if a person is drawing with deployed nib 116 and wants to erase some portion, feature, etc. of what they have drawn, then traditionally, the person would have to find an eraser and then erase that portion, feature, etc. If no eraser is available, the person would generally use their hand or fingers, which can create a mess. In addition, if the detail to be erased is small, a traditional eraser is often ill-suited and can erase more than intended. Detail eraser 155 proximal to deployed nib 116 provides quick, convenient, and accurate eraser capabilities. The person using dry-erase marker 100 does not even need to lower dry -erase marker 100 from the white board or re-orient dry-erase marker 100 in the person’shand. A slight bend of the wrist is all that is needed to engage detail eraser 155 with the white board, as opposed to deployed nib 116. Detail eraser 155 can be replaceable, as necessary, so as to extend the useful like of dry -erase marker 100.

[0053] In addition to detail erasers proximal to each nib, dry-erase marker 100 can be designed to incorporate a full-size eraser as well. Dry-erase marker 100 can include a latch between an interface of two adjacent housing sections. The latch can be a positive lock, friction, magnetic, and / or any other suitable way in which to secure dry-erase marker 100 in the form illustrated in Fig. 1. The two adjacent housing sections forming the latch can include a groove 160 that provides leverage for a user to apply the force necessary to disengage the latch. The remaining interfaces between adjacent housing sections may include hinges. Upon disengaging the latch, dry-erase marker 100 can be unfolded, unrolled, laid flat, etc. This action can reveal an eraser element that is disposed on the inside surfaces of each discrete housing section of dryerase marker 100.

[0054] Dry-erase marker 100 can provide four discrete colors, but it should be appreciated that dry-erase marker 100 can be configured to include more or less colors (e.g., 1, 2, 3, 5, 6, 7, 8, etc.).

[0055] Turning to Fig. 2, an exploded view illustrating the construction of an exemplary dryerase marker 200 is provided. Dry erase marker 200 can include marker body 205 that can be constructed of any suitable material including injection molded plastic, metal, etc. Marker body 205 can have a rounded, beveled, tapered, or otherwise reducing form on a proximal end to maximize protrusion of nibs 225 when deployed and to ensure the greatest potential angle achievable between a white board and any of the nibs 225 during writing, drawing, etc. Such exemplary design can improve and / or maximize the ergonomics for all users.

[0056] Marker body 205 can include cartridge housing sections 205(a), 205(b), and 205(c) which can accommodate the plunger cartridges. As shown in Fig. 2, cartridge housing section 205(b) includes two plunger cartridges while 205(a) and 205(c), each having one plunger cartridge. It should be noted that other configurations are possible with one or more plunger cartridges per housing section.

[0057] Fig. 2 shows that hinges 210 are located between cartridge housing sections 205(a) and 205(b) as well as between 205(b) and 205(c). Hinges may be any flexible material suitable for allowing relative movement between the relevant adjacent housing sections, such as rubber,fabric, etc. A latching mechanism is located between 205(a) and 205(c). In exemplary Fig. 2, the latching mechanism can be magnetic, as implemented, e.g., by magnets 215. While magnets 215 are used as the latching mechanism in this exemplary configuration, it should be appreciated that other types of latches or connections can be employed.

[0058] Detail erasers 220 can be affixed to the outside of the marker body 205 proximal to each aperture, e.g., where the nib of a deployed color segment extends from the marker body 205.

[0059] Nibs 225 can be part of plunger cartridges 230, and can be replaced as a complete assembly. Alternatively, nibs 225 can be provided separate from plunger cartridges 230, where each of nibs 225 and plunger cartridges 230 can be separately replaceable. Nibs 225 may insert into a proximal end of plunger cartridges 230 in order to transmit the marker ink from plunger cartridges 230 through the tips of nibs 225 onto a writing surface when the nib is in a deployed configuration. Springs 235 can be configured to surround a shaft portion of plunger cartridges 230. Springs 235 can be configured to be retained within cartridge housing sections 205(a), 205(b), and 205(c). Alternatively, springs 235 can be configured to remain attached to plunger cartridges 230 in order to protect lubricant on the shaft portion of plunger cartridges 230 from being touched when handling plunger cartridge 210.

[0060] Plunger cartridges 230 can be configured to fit within housing sections 205(a), 205(b), and 205(c). Further, plunger cartridges 230 can be configured to interface with housing sections 205(a), 205(b), and 205(c), as well as with cartridge release buttons 250 to control the orientation of nibs 225 - either in a deployed or retracted configuration. In some exemplary embodiments of the present disclosure, cartridge release buttons 250 can be bonded to housing sections 205(a), 205(b), and 205(c). Cartridge release buttons 250 can be plastic, metal or any other rigid or semi-rigid material.

[0061] A proximal end of ink packs 240 can be inserted into a distal end of plunger cartridges 230 in order to provide the ink for nibs 225. Ink packs 240 can be individually replaceable. Alternatively, or in addition to, ink packs 240 can be replaced as an assembly with plunger cartridges 230. In some exemplary embodiments, if a color runs out for one of the color segments of dry-erase marker 200, the corresponding ink pack 240 may be replaced. However, if the user wants to change a color, e.g., from blue to red, then the entire cartridge, nib, and ink pack assembly should be replaced. This is because the nib soaks up the ink, and therefore likelycannot change color without replacement. Exemplary methods and apparatuses according to the exemplary embodiments of the present disclosure can provide for ink refills and color swaps in each discrete marker segment.

[0062] For example, plunger caps 245 attach to the distal ends of ink packs 240, and can also create a friction fit with the distal end of plunger cartridges 230. Plunger caps 245 can serve to deploy nibs 225 when pressed by a user. Pressing a plunger cap 245 with an axial force results in an axial movement along the length of dry-erase marker 200. This axial movement can result in a plunger cartridge 230 engaging with one of the cartridge release buttons 250 such that the plunger cartridge 230 is held in a position when the nib 225 is in a deployed state. Each plunger cap 245 can control a single marker segment. Plunger caps 245 can be plastic, metal, or any other material depending on design goals for overall weight, feel, balance, quality, etc. of dryerase marker 200.

[0063] As described in more detail herein, when nibs 225 are in a retracted configuration, seal sub-assemblies 255 can seal or prevent the nibs 225 from being exposed to the air.

[0064] Each housing section, 205(a), 205(b), 205(c) can include housing covers 260 that attach to the housing sections, and close and / or seal the housing section. Housing sections 205(a), 205(b), 205(c), along with housing covers 260, can provide the cavity that receives springs 235, nibs 225, plunger cartridges 230, ink packs 240, and seal sub-assemblies 255.

[0065] Main eraser 265 can be made partially or entirely of a felt material, or any other material suitable for removing dry-erase marker ink from a surface such as a white board. Main eraser 265 may be attached to housing covers 260 by any number of means. For example, main eraser 265 can be attached via adhesive, clips, Velcro, or any other ways. Main eraser 265 can be replaceable so as to extend the useful life of dry-erase marker 200. Main eraser 200 can comprise any shape that mimics the housing covers 260, and may include one or more creases perforations, or independent sections as necessary such that the dry-erase marker 200 may be folded or rolled up into the general shape of dry-erase marker 100 in Fig. 1. The material specifications of main eraser 200, including material type, material thickness, and / or attachment is selected to allow for dry-erase marker 200 to be folded or rolled up into the general shape of dry -erase marker 100 in Fig. 1.

[0066] As shown in Fig. 3, dry-erase marker 300 can be fully modular. Each discrete marker segment of dry-erase marker 300 can accommodate a plunger cartridge assembly. For example,Fig. 3 illustrates plunger cartridge assembly 310 removed from its discrete housing section of dry -erase marker 300. Plunger cartridge assembly 310 can include one or more of a nib 315, a spring 320, a plunger cartridge 325, an ink pack 330, and a plunger cap 335. In some exemplary embodiments, plunger cap 335 may be removable from plunger cartridge 310 and / or ink pack 330. In some exemplary embodiments according to the present disclosure, ink pack 330 can be removable from plunger cartridge 325. In this exemplary way, dry-erase marker 300 is fully modular. For example, if a marker segment of dry-erase marker 300 has run out of ink or otherwise run dry, ink pack 330 may be replaced independent of plunger cartridge assembly 310, either with or without plunger cap 335. Further, if the user prefers to change a color or nib tip shape, then the entire plunger cartridge assembly 310 can be removed and replaced. A replacement cartridge assembly 310 can be provided with or without spring 320.

[0067] As indicated herein, plunger cartridge 310 can include spring 320. Alternatively, spring 320 can remain in the housing when plunger cartridge 310 is removed. In some methods and apparatuses according to exemplary embodiments of the present disclosure, it can be preferred for plunger cartridge 310 to retain spring 320 in order to help protect the lubricant on plunger cartridge shaft from being touched when handling plunger cartridge 310.

[0068] Figs. 4(a) - 4(d) illustrate transparent views of dry-erase marker 400 where marker segment 410 is in the deployed configuration and other marker segments, such as segment 420, are in the retracted configuration. Fig. 4(a) provides a transparent perspective view of dry-erase marker 400 while Figs. 4(b), 4(c), and 4(d) provide transparent side, front, and back views, respectively. As illustrated in Figs. 4(a) - 4(d), marker segment 410 can include plunger cartridge assembly 430, and such assembly can include a nib 435, a spring 440, a plunger cartridge 445, an ink pack 450, and a plunger cap 455. In the deployed state, spring 440 is in a maximally compressed state. This is in contrast to spring 460 from retracted market segment 420, which is in a minimally compressed or uncompressed state. Fig. 4 further illustrates that in the deployed configuration, seal sub-assembly 475 of marker segment 410 is depicted in the open position, thereby facilitating nib 435 to pass through seal sub-assembly 475 and to protrude from aperture 465 in body 470 of dry-erase marker 400. This is in contrast to seal sub-assembly 480 from retracted marker segment 420 which is depicted in the closed position. The closed position can protect a retracted nib from the open air which can dry out and ultimately damage nib 435.

[0069] Figs. 5(a)-5(h) show cross sections of a single marker segment 500 of a dry-erase marker according to exemplary embodiments of the present disclosure, and illustrate the deployment, retraction, and removal of a plunger cartridge assembly of a dry-erase marker in exemplary methods and apparatuses according to exemplary embodiments of the present disclosure. For example, Fig. 5(a) illustrates the condition where a nib is in the retracted position. In this position, a spring force applied by spring 510 to plunger cartridge assembly 515 is at a minimum. Cartridge release button 520 can include a proximal and a distal end, and can be connected to a marker body 505 in a central location. The cartridge release button 520 can include a tooth 525 on the proximal end and a release button 526 on the distal end. Tooth 525 can engage with a first shoulder 530 of plunger cartridge assembly 515 to prevent removal of plunger cartridge assembly 515 from the dry-erase marker.

[0070] Exemplary Fig. 5(b) illustrates the condition where a user is applying an axial force to plunger cap 560. In this case, plunger cartridge assembly 515 has begun to move in an axial direction congruent with the applied axial force. The movement of the plunger cartridge assembly 515 causes a second shoulder 535 of plunger cartridge assembly 515 to engage with tooth 525 and push the proximal end of cartridge release button 520 away from plunger cartridge assembly 515 in a radial direction. As the proximal end of cartridge release button 520 moves away from plunger cartridge assembly 515, the distal end of cartridge release button 520 simultaneously moves closer to plunger cartridge assembly 515. Thus, cartridge release button 520 can pivot like a see-saw. During this axial movement, the spring force applied by spring 510 (not shown) against plunger cartridge assembly 515 is increasing.

[0071] In Fig. 5(c), the nib of plunger cartridge assembly 515 reaches the deployed state. In this configuration, the force applied by spring 510 (not shown) against plunger cartridge assembly 515 is at a maximum. Further, in this configuration, the cartridge release button 520 has returned to a neutral position relative to the plunger cartridge assembly 515. This can result in the second shoulder 535 of plunger cartridge assembly 515 being fully engaged with tooth 525, thereby preventing nib retraction into the dry-erase marker.

[0072] Fig. 5(d) illustrates the case where the user begins the process to place the marker segment in a retracted position. IN this exemplary case, a user can push the release button 526 thereby forcing the distal end of cartridge release button 520 closer to plunger cartridge assembly 515 and the proximal end of cartridge release button 520 away from plunger cartridge assembly515. The movement of the proximal end of cartridge release button 520 away from plunger cartridge assembly 515 causes tooth 525 to disengage from second shoulder 535. Once tooth 525 is no longer engaged with second shoulder 535, the spring force applied to plunger cartridge assembly 515 by spring 510 (not shown) causes axial motion of plunger cartridge assembly 515 in a direction congruent with the spring force.

[0073] Fig. 5(e) illustrates the transition of the plunger cartridge assembly 515 from a deployed position to a retracted position upon the user pressing button 526. In this exemplary scenario, the nib is retracting and the force generated by spring 510 (not shown) is decreasing as the plunger cartridge assembly 515 is moving back to is retracted state. A cam can force the distal end of cartridge release button 520 back into a neutral position before the plunger cartridge assembly 515 fully retracts.

[0074] Fig. 5(f) shows the starting position and is the same configuration as illustrated in Fig. 5(a).

[0075] Fig. 5(g) illustrates the process of removing plunger cartridge assembly 515 from marker body 505. Starting from the retracted position illustrated in Figs. 5(a) and 5(f), the user can push button 526 which causes the proximal end of cartridge release button 520 to move away from plunger cartridge assembly 515. This movement causes tooth 525 to fully disengage first shoulder 530. At this point, a user may pull plunger cartridge assembly 515 out of marker body 505 via a plunger cap. As illustrated in Figs. 5(g) and 5(h), as the plunger cartridge assembly 515 is being removed from marker body 505, second shoulder 535 can engage with a ramp feature under the distal end of cartridge release button 520, thereby causing or forcing cartridge release button 520 back into a neutral position. It should be noted that while some embodiments of the present disclosure include a novel single button configuration for nib retraction and cartridge removal, other embodiments are possible. For example, some exemplary embodiments of the present disclosure can include separate nib retraction buttons and cartridge release buttons, levers, etc.

[0076] In some exemplary embodiments, the plunger cap and ink pack can be removed from the marker body without removal of the entire plunger cartridge assembly. This may be accomplished by, starting from the retracted position of Figs. 5(a) and 5(f), simply pulling on the plunger cap without first pressing button 526 to release plunger cartridge assembly 515.

[0077] Fig. 6 illustrates the shape and features of a plunger cartridge assembly 610. Tn this Fig., ink pack 615 and plunger cap 620 have been removed. In some embodiments, the ink pack 615 and plunger cap 620 can form a portion of the plunger cartridge assembly 610 that can be independently replaced. Plunger cartridge 625 of plunger cartridge assembly 610 illustrates features for mechanical interaction with a cartridge release button, such as first shoulder 630 and second shoulder 635, as well as a spring shoulder 640.

[0078] Fig. 7 illustrates a cross sectional view of plunger cartridge assembly 710. Plunger cap 715 is provided which can be attached to plunger cartridge 720 through an annular snap-fit and interference seal. This type of positive connection can provide a seal sufficient to avoid ink leakage or evaporation. Plunger cartridge 720 and plunger cap 715 can be injection molded plastic, or any other material sufficient to achieve a design goal, such as cost, size, weight, balance, appearance, etc.

[0079] Figs. 8 and 9 illustrate exemplary function of seal sub-assemblies within exemplary dry -erase markers according to exemplary embodiments of the methods and apparatuses of the present disclosure. In particular, Fig. 8 shows an axial cross section showing two marker segments 805 and 810, one in the deployed state, and one in the retracted state 810. Marker segment 805 includes plunger cartridge 815 with nib 820 installed therein. A shaft 816 of plunger cartridge 815 can be configured to move axially when deployed and / or retracted. In marker segment 805, seal sub-assembly 825 is in an open position and shaft 816 is passing therethrough. Seal sub-assembly 825 has a seal cap 830 that is forced open by shaft 816 and held in an open position by shaft 816 for as long as marker segment 805 is in a deployed state. Seal cap 830 of seal sub-assembly 825 can be spring loaded such that its natural resting state is a closed position. In the retracted state of marker segment 810, shaft 840 of plunger cartridge 835 is not forcing seal cap 850 of seal sub-assembly 845 into an open state. As a result, seal cap 850 is in its resting state which can be a closed position. The closed position can protect nib 855 from drying out. Seal sub-assemblies 825 and 845 can include a hinge for seal caps 830 and 850 as well as a thin rib, 860 and 865, for improved sealing of seal caps 830 and 850. It should be appreciated that seal sub-assemblies 825 and 845 can be installed within the marker housing, or alternatively can be attached to, and therefore part of, a plunger cartridge assembly.

[0080] Fig. 9 shows a perspective transparent view of a dry-erase marker with a cross- sectional cut near the seal sub-assemblies for better visibility. Fig. 9 illustrates the samecomponents and operation as Fig. 8, although with a three-dimensional view of the seal subassemblies.

[0081] Figs. 10(a) - 10(d) illustrate a seal sub-assembly 1005 relative to a plunger cartridge shaft and nib assembly 1025 according to exemplary methods and apparatuses of the present disclosure. Figs. 10(a) and 10(b) provide a three dimensional view of a seal sub-assembly 1005 in a closed position, where Fig. 10(a) is a transparent seal sub-assembly 1005 and Fig. 10(b) is an opaque seal sub-assembly 1005. Fig. 10(c) shows an exemplary view of opaque seal subassembly 1005 in an open position. Fig. 10(d) shows a different angle of seal sub-assembly 1005.

[0082] Figs. 10(a) and 10(b) show side transparent and non-transparent view of the seal subassembly relative to the plunger cartridge assembly, illustrating that seal sub-assembly 1005 can have a wire spring 1010. For example, a first end of wire spring 1010 can be embedded and / or installed into seal sub-assembly 1005. A second end of wire spring 1010 can be positioned over seal cap 1015. The first end can be captive, and / or the second end can be held in torsion by virtue of the captive first end and the routing of the wire spring 1010 such that the second end terminates over seal cap 1015. As a result, wire spring 1010 can apply torsional force against seal cap 1015. This torsional force can be sufficient to maintain a seal between seal cap 1015 and a seal sub-assembly body 1020 when seal sub-assembly 1005 is in a closed position. The torsional force likely increases as the plunger cartridge shaft and nib assembly 1025 are forced through seal sub-assembly 1005. As the plunger cartridge shaft and nib assembly 1025 are forced through seal sub-assembly 1005, wire spring 1010 can slide over the top of seal cap 1015.

[0083] As provided in Figs. 10(a) - 10(d), seal sub-assembly body 1020 can include a rubber portion 1021 and a hard plastic portion 1022. Rubber portion 1021 can facilitate a creation of a seal between the seal sub-assembly 1005 and the plunger cartridge shaft of the plunger cartridge shaft and nib assembly 1025. The annular seal geometry in the rubber portion 1021 can facilitate sealing and also relative movement between rubber portion 1021 and the plunger cartridge shaft. As a result, the plunger cartridge shaft can prefer to have at least some lubrication to avoid wear and ultimately failure.

[0084] Rubber portion 1021 can also provide a thin rib 1023 on the sealing surface of rubber portion 1021 where seal cap 1015 rests when in the closed position. Hard plastic portion 1022 can help maintain torsion on wire spring 1010, as well as hold the rubber position 1021 in place.Seal cap 1015 may include hard plastic as well. Seal cap 1015 and hard plastic portion 1022 of seal sub-assembly body 1020 can be one continuous plastic part separated by a hinge 1030. Hinge 1030 can be molded into the plastic.

[0085] Figs. 11(a) and 11(b) show dry-erase marker 1100 in a folded-out configuration for use as an eraser. Fig. 11(a) shows an inner unfolded surface of dry-erase marker 1100 along with surface 1105 of the eraser. Fig. 11(b) shows the reverse side of dry-erase marker 1100 (e.g., generally the outer surface held in hand by the user). When dry-erase marker 1100 is folded-out, the surface 1105 of the eraser is flat to ensure maximum contact with a surface to be erased, such as a white board. Magnet 1110 can be located on the side of dry-erase marker 1100 and a complementary magnet (not visible) can be located on the other side of dry-erase marker 1100. These magnets can work together to latch dry-erase marker 1100 when in the closed writing configuration. In some exemplary embodiments, a series of features 1115 formed into the dryerase marker 1100 can be provided. These exemplary features can facilitate an engagement with features on the other side of dry-erase marker 1100 (not visible) such that when dry-erase marker 1100 is folded into the closed configuration, the features 1115 mechanically interlock to help align and fix dry-erase marker 1100 in the closed configuration. Grooves 1120 provide the user with leverage to apply the force necessary to open dry-erase marker 1100 from its closed position. The force required to open dry-erase marker 1100 can be calibrated based on the size and strength of magnets 1110 as well as the features 1115. In some embodiments, it can be preferrable to configure the latch such that the user can open dry-erase marker 1100 with one hand while avoiding contact with eraser surface 1105. For example, when dry-erase marker 1100 is in the unfolded configuration, there is nothing stopping a user from deploying one or more marker segment and drawing on a surface.

[0086] Fig. 12 depicts a partially exploded view of dry-erase marker 1200 in the unfolded configuration. Eraser material 1210 can be attached to dry-erase marker 1200, and can be fully replaceable. Eraser material 1210 can be attached in any number of ways, and in some exemplary embodiments, the eraser material 1210 can include an adhesive backing. This can provide for the thinnest possible part, and can facilitate the user to peel eraser material from dryerase marker 1200 and replace with adhesive backed replacement eraser pads. The thickness of eraser material 1210 can be 0.4mm - 0.8mm. This thickness can facilitate dry-erase marker1200 to fold into the closed position. Dry-erase marker 1200 can include a third magnet 1215 inthe middle of dry-erase marker 1200. This third magnet 1215 can work together with the other latch magnets 1220 to hold dry-erase marker 1100 in the closed configuration, and can assist holding the eraser to a dry erase white board.

[0087] Fig. 13 illustrates a section view of dry-erase marker 1300 in the folded-out configuration. Bump outs 1305 can make space for the cartridge release buttons and create a hard-stop to ensure that the assembly folds out and stops at the right angle.

[0088] Fig. 14 shows another exemplary embodiment of a dry-erase marker 1400 of the present disclosure. The exemplary dry-erase marker 1400 can facilitate deployment s), extension(s) and / or dispensing of dispense multiple different marker colors and / or tips from a single device.

[0089] For example, the dry-erase marker 1400 can include a plurality of individual marker segments that can have a shared housing (e g., a shared marker body), which together can form the dry-erase marker 1400. The marker segment of dry-erase marker 1400 can include a single aperture 1405 at a proximal end thereof. As a result, each color wick or nib from a respective segment can be separately and / or simultaneously extended and / or deployed as shall be further discussed herein. For example, the dry-erase marker 1400 of Fig. 14 with one marker segment activated, resulting in deployed nib 1416 extending through the single aperture 1405. The other marker segments are each depicted in a retracted position, as reflected by retracted nibs 1417, 1418, and 1419. Each marker segment can be activated and the corresponding nib deployed by pressing down one of the plunger caps, 1425, 1430, 1435, and a fourth plunger cap (not visible in Fig. 14), at a distal end of the marker.

[0090] The exemplary dry-erase marker 1400 can be fully modular. For example, the colors, nib shape, and configuration of the dry-erase marker 1400 can be changed by the user. When more than one nib is deployed, the dry-erase marker 1400 can provide multiple concurrent lines, colors, and or line shape / thickness by extending multiple wicks / nibs out of aperture 1405 of the dry-erase marker 1400. The orientation and combination of colors used while writing or drawing can be selected by the user through color deployment (e.g., by pressing a combination of plunger caps 1425, 1430, 1435, etc.) and through user selection of which colors and / or nib shapes to include in the dry-erase marker 1400, as well as the orientation of those colors and / or nib shapes within Dry-erase marker 1400. The exemplary dry-erase marker 1400 can be modular in color selection and orientation, as well as in a design of the nibs / wicks. For example, nib 1416depicted in Fig. 1 is a standard blunt tip, although the user can change the nib to one of any other nib shape such as chisel, super fine, semi-broad, calligraphy, round, brush, etc. As indicated, the dry -erase marker 1400 can be configured with different colors and / or nib shapes. For example, the dry-erase marker 1400 can be configured with four green sections, all with different nib shapes, four different colors all with the same nib shape, or any combination in-between. Exemplary dry-erase marker 1400 is depicted with 4 discrete sections but other exemplary embodiments may include more or less discrete sections.

[0091] A deployed nib can be retracted by pressing a corresponding retraction button such as a retraction button 1445. Each discrete marker segment in the dry-erase marker 1400 can have its own retraction button for independent operation.

[0092] Further, a circumferential detail eraser 1450 can be provided adjacent to the proximal end of the dry-erase marker 1400. As the detail eraser 1450 extends around the circumference of the dry-erase marker 1400, it is adjacent to each nib that is in a deployed state. The detail eraser 1450 can be convenient when writing or drawing with the dry-erase marker 1400. For example, in operation, if a person is drawing with deployed nib 1416 and wants to erase some portion, feature, etc. of what they have drawn, then traditionally, the person would have to find an eraser and then erase that portion, feature, etc. If no eraser is available, the person would generally use their hand or fingers, which can create a mess. In addition, if the detail to be erased is small, a traditional eraser is often ill-suited and can erase more than intended. The detail eraser 1450 proximal to deployed nib 116 provides quick, convenient, and accurate eraser capabilities. The person using the dry-erase marker 1400 does not even need to lower the dry-erase marker 1400 from the white board or re-orient the dry-erase marker 1400 in the person’s hand. A slight bend of the wrist is all that is needed to engage the detail eraser 1450 with the white board, as opposed to deployed nib 1416. The detail eraser 1450 can be replaceable, as necessary, so as to extend the useful like of dry-erase marker 1400.

[0093] Additionally, the dry-erase marker 1400 can include a cap 1470. This cap 1470 can be configured to enclose all of the nibs of dry-erase marker 1400 when not in use. The cap 1470 can be configured to snap onto the proximal end of the dry-erase marker 1400 to prevent the nibs from drying out due to air exposure. In some exemplary embodiments, the cap 1470 can be configured to attach to the proximal end of dry-erase marker 1400 via threaded engagement, press fit, positive lock, or any other manner in which to ensure that the cap 1470 remainsinstalled on the dry-erase marker 1400 when the marker is not in use and all nibs are in the retracted state. In order to prevent potential damage to any of the nibs, e.g., the cap 1470 can be designed to be deep enough to engage and seal the proximal end of the dry-erase marker 1400 without touching a nib in the deployed state. As shown in Fig. 14, the cap 1470 can be configured to attach to a distal end of dry-erase marker 1400 when the marker is in use. In some exemplary embodiments, the cap 1470 can include a male tab or female socket configured to mate to a reciprocal part on the distal end of the dry-erase marker 1400. In the exemplary dryerase marker 1400, the cap 1470 can include a female tab configured to attach to a male tab on the distal end of the dry-erase marker 1400. This interface can be a press fit, threaded, snap fit, or any other way to ensure positive retention of the cap 1470 when the dry-erase marker 1400 is in use.

[0094] Dry-erase marker 1400 can provide four discrete colors, but it should be appreciated that dry-erase marker 100 can be configured to include more or less colors (e.g., 1, 2, 3, 5, 6, 7, 8, etc.).

[0095] Fig. 15 shows a side view of the exemplary dry erase marker of Fig. 14. This figure shows the cap 1570 installed on the proximal end of the dry erase marker, thereby sealing all of the nibs (regardless of deployed or retracted position). A threaded stopper 1575 on the distal end of the dry erase marker for retaining the cap 1570 is also visible. The threaded stopper 1575 can help to ensure positive retention of each a cartridge body in the dry erase marker.

[0096] Fig. 16 illustrates an exploded view of an exemplary construction of the exemplary dry-erase marker 1600 is provided. The dry erase marker 1600 can include a marker body 1615 that can be constructed of any suitable material including injection molded plastic, metal, etc. The marker body 1615 can be relatively uniform in diameter from a proximal to a distal end. A marker body front end 1610 can be configured to mate to the proximal end of marker body 1615. The marker body front end 1610 can attach to the marker body 1615 via engaging threads or any other way of ensuring positive retention.

[0097] The marker body front end 1610 can have a rounded, beveled, tapered, or otherwise reducing form on a proximal end to maximize protrusion of nibs 1640 when deployed and to ensure the greatest potential angle achievable between a white board and any of the nibs 1640 during writing, drawing, etc. Such exemplary design can improve and / or maximize the ergonomics for all users. The marker body front end 1610 can include an internal frame withapertures for passage of each nib 1640 and a portion of each cartridge body 1645 therethrough. The internal frame of marker body front end 1610 and the respective apertures can serve as a bearing surface and support for each cartridge body 1645, and to reduce or minimize a deflection of each nib 1640 when pressed against a white board at any angle of incidence common for writing or drawing. The exemplary dry erase marker 1600 can further include an elastomeric seal 1605 that can be pressed into the internal frame of the marker body front end 1610. Elastomeric seal 1605 can work in conjunction with the internal frame of the marker body front end 1610 to guide and support each cartridge body 1645. The internal frame of marker body front end 1610 can also serve as a bearing surface on a proximal end for a proximal end of cartridge springs 1635. Each cartridge spring 1635 can interface on a distal end with a spring retaining shoulder of each cartridge body 1645. The cartridge springs 1635 can provide a retracting force for each cartridge body 1645 and each respective nib 1640 when a user presses a release button 1630 when the corresponding nib 1640 is in the deployed position.

[0098] The detail eraser 1650 can be installed circumferentially on the outer diameter of marker body front end 1610. The detail eraser 1650 can be configured to be removable for replacement so that the life of the dry erase marker 1600 is not limited by the life of the detail eraser 1650.

[0099] The cap 1670 can be configured to mate with a proximal end of marker body front end 1610. As discussed with respect to Fig 14, the cap 1670 can attach to the marker body front end 1610 via threaded engagement, snap, press fit, and / or any other way in which to ensure positive cap retention.

[0100] The back frame 1620 can be configured for installation into the distal end of the marker body 1615 and can serve as the male tab for retention of the cap 1670 when the dry erase marker 1600 is in use. Back frame can include threads for receiving a threaded stopper 1625 that can serve as a positive retention for each cartridge body 1645. In some exemplary embodiments, back frame 1620 and threaded stopper 1625 can be consolidated into a single piece. The back frame 1620 can provide internal bracing for the dry erase marker 1600 and also serve to separate each cartridge body 1645 and guide each plunger cap 1655 when pressed by a user to cause deployment of the nib 1640. Each plunger cap 1655 can be attached to a respective cartridge body 1645, where each cartridge body 1645 is configured to house an ink pack 1655.

[0101] An assembly of a nib 1640, a cartridge body 1645, an ink pack 1655, either with or without a plunger cap 1655 can comprise a replacement cartridge assembly for the dry erase marker 1600. Such a replacement cartridge assembly can initially include the cartridge cap 1680 to ensure nib freshness prior to installation in the dry erase marker 1600. The cartridge cap 1680 can be discarded upon installation of the replacement cartridge assembly into the dry erase marker 1600.
