Description
BACKGROUND

1. Field


The present invention relates to the field of paper, plastic or other rolled substrates and more particularly to roll kits that include a clamshell-shaped storage facility and dispensing feature for rolls along with a separate compartment(s) for utility items, wherein the storage facility includes or does not include a handle.


2. Description of the Related Art


Multiple existing designs of paper rolls are provided that are suitable for various purposes. One of the existing designs of paper rolls includes a hollow base or core made of material such as cardboard or plastic or may be wound without a core. Paper of a defined length, type, and size is wound around the hollow base. The end of the wound roll thus formed is finally sealed and or packaged to be opened whenever required for use. Consumers remove the seal and use the paper roll for the desired purposes. When all of the paper wound around the core is consumed, the cardboard or plastic core can be discarded, reused or recycled. However, according to the technologies of existing paper rolls, the hollow space inside the base material have not been used for any reason than as a means of wrapping the paper around and to add extra stability or certain functionality to the product itself. Further, paper rolls available in the market are merely a simple source of paper for an intended purpose and a custom designed kit whereby the core itself is used as a storage compartment while the paper is still wrapped around a core or a hollow space is not available in the existing art. Furthermore, a paper roll placed in a clamshell dispenser with a built-in storage will dispense rolled paper in a similar fashion to a wound paper roll.


An unmet need and opportunity, therefore, exists for the improved design, functionality and reusability of paper roll kits that also utilize the hollow space inside the core or clamshell dispenser with built-in compartment(s) in order to maximize space, avoid wastage of paper and packaging, reduce the need for extra carry containers to hold the same utility items and other objects which may be custom designed for various applications and may act as a source of various elements of daily use.


SUMMARY

System and apparatus of the present invention provide a paper roll kit that includes a core adapted to receive utility elements. The core is rotatable along an axis of rotation, which may be coincident with the axis of the core. A length of paper may or may not be wrapped around the core about the axis of rotation. Likewise, a length of paper either wrapped or not wrapped around a core, may placed inside and be dispensed through a slot in the outside core or dispenser by rotating the inside core about the axis of rotation or by being pulled from a clamshell dispenser providing the same results. The hollow space inside the core or built-in compartment(s) may facilitate storage of utility elements in it regardless of whether or not it is wound around a core. Further, in one embodiment one or more caps or plugs may be provided for storing the utility elements in the outer tube or dispenser; the one or more caps or plugs may also act as a cover to the outside tube or dispenser. One end of the core may also be sealed permanently while the other end contains a removable cap or plug. The plug or cap may be designed such that the center of the cap may be inserted into the center of the roll to be used not only as a way to secure the end of the inside or outside tube but also as a means to turn or spin the paper roll thus causing the paper to be dispensed or refracted as desired. In addition, the center cap may or may not have a turning mechanism or attached flip top protruding from the top of the cap. The mechanism may enable the center cap to be easily removed or opened in order to access the contents stored inside the center tube as well as act as a means of turning the inside core thus dispensing or retracting the paper. The cap may be designed so that it is taught with the outside edge of the core yet spins the inside core. The cap may also spin about the outside of the core as well as the inside core concurrently. The cap designed to turn the central core may be situated on the top or the bottom of the core. In all configurations the Center most tube may be used as a storage facility for utility elements.


The utility elements may be writing utensils, stationery elements, eatables, toys and the like depending on the kit and requirements and use of the paper.

DETAILED DESCRIPTION

While the specification concludes with the claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the drawings and figures, in which like reference numerals are carried forward.


As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure. Further, the terms and phrases used herein are not intended to be limiting but rather to provide an understandable description of the present invention.


The terms “a” or “an” as used herein, are defined as one or more than one. The term “another,” as used herein, is defined as at least a second or more. The terms “including” and/ or “having” as used herein, are defined as comprising (open transition).


The present disclosure relates to improved designs of paper rolls and clamshell dispensers for dispensing the rolls, along with kits that also utilize the hollow space inside the paper roll core or within the clamshell design in order to maximize space, provide convenient dispensing benefits and avoid wastage of paper and packaging. The paper roll may come in many embodiments, such as with or without a core at the center and with or without a surrounding sleeve, wherein the sleeve may have one or more of a slot for dispensing, an angled cutting edge, and a serrated cutting edge, the sleeve may enclose the ends, and the sleeve and any associated cap may have any ornamental design. The paper roll may come with a rip strip for cutting the paper, or an associated flat surface that is rolled around the paper. In some embodiments, a flexible display may roll up to create a tube inside which utility elements may be stored as described herein with or without the use of caps or any combination of caps described herein. The paper roll may be dispensed from a clamshell-shaped package that may also house utility items stored in a separate built-in compartment accessible without interfering with the roll or its ability to be dispensed from the core or clamshell. The cap may fit inside the core or may fit over the paper roll and they may be flat or have a protrusion. The cap may have an internal space for storing items that may be accessed by opening the cap or simply removing the cap from the paper roll. The cap may also have a rotary tool such that the cap can be used to rotate the paper roll when affixed to a substantially stationary object. Indeed, the paper roll may be any sort of paper. Alternatively, the roll may be wound with a dry-erase material, a chalkboard material, a plastic material, or any other useful material, either in a continuous roll or as separate sheets of material, with a writing surface.



FIG. 1 illustrates a paper roll kit 100 in accordance with an embodiment of the present invention. The paper roll kit 100 may include a core, a paper wrapped around the core and one or more caps attached to the core.


The core may form a base to wind a length of paper. The length of paper may vary as per the needs and requirements. The shape of the core is usually hollow and cylindrical. However, it should be understood that the shape of the core does not limit the present invention and other possible shapes of the outside core or dispenser may also be used. The core may be made of cardboard, plastic, wood, metal, bio-degradable material, a wire mesh, or some other type of material. The core may be rotatable around an axis of rotation. The axis of rotation may coincide with the axis of the core. In embodiments, the orientation of the axis of rotation may be horizontal, vertical or inclined at an angle to the horizontal or vertical side.


In embodiments, the paper may be wrapped around the outside of the core. In yet another embodiment, as shown in FIG. 5, a wound paper roll with or without a core may be inserted inside the core or clamshell and dispensed from a slot, 503, in the core or the entire roll may be removed and used without using the slot. The slot, 503, may be configured in the best way to insure the paper can be easily dispensed and rerolled if needed. To insure the dispensed paper will tear easily, any angle such as a 45 degree angle may be cut at the top and or bottom of the slot as seen in FIG. 7. In embodiments, such an angle will cause a remaining protruding piece of paper to be left after the sheet is torn from the roll. This remaining piece of paper provides a means for the user to access the paper to manually dispense additional paper from the roll. The length of paper unwound may be manually or mechanically determined based on an extent of rotation. Further, a portion of the length of the paper may be dispensed or unrolled by rotating or spinning the center core around the axis of rotation or the paper may be retracted through the slit, 503, when turned in the reverse direction. Likewise, the length of the paper dispensed or unrolled may depend on the extent of the rotation. In embodiments, a circular, oval or other shape, 700, may be cut into the outside tube on both sides of the slot to provide a means of access to the paper in the tube. In other embodiments a circular, oval or other shape, 700, may be cut into the outside tube on one side of the slot to provide a means of access to the paper in the tube. In embodiments, the circular, oval or other shape may be located on the right side of the slot while in other embodiments it may be located on the left side of the slot. In embodiments, a serrated slot, 700, may be used to provide a means of tearing a length of paper. In embodiments, the serrated edge may contain a circular, oval or other shape on one side of the slot to provide a means of access to the paper. In embodiments, the circular, oval or other shape may be located on the right side of the serrated slot while in other embodiments it may be located on the left side of the serrated slot. It should be clearly understood that the terms dispensing and unrolling of the paper are interchangeably used throughout the description without any change in meaning When the paper roll is wound around the core it may be secured to maintain tautness by using strings, taut bars, bands such as hair bands, bracelets, elasticized band watches, stickers and the like. Further, the end caps may also be used for securing purposes, and or applications whereby the cap or plug is made in such a way to serve as a tube and a plug at the same time. In addition, the plug or exterior tube may be customized in a variety of ways and in the form of an eraser, sharpener, crayon, caricature, action figure, hanging tab, clip, and the like. The plug may be completely removed from the core or may be attached using a string or other accessory.


The paper wound around the core may be used for various purposes and accordingly size, shape and design aspects of the paper may vary. For example, the paper wound around the paper roll may be used as for arts and crafts, gift-wrap, presentations, stationery and the like. The paper may be utilized for tracing, sketching, painting, writing, coloring, scratching, sniffing, artwork, or as a cardstock, construction paper, poster, magic/chemically active or adhesive paper or other substrates and the like. Hence, the paper type may accordingly vary depending on the purpose. The wound paper may be white or colored, coated or uncoated; plain to write on or may be provided with artwork on one or both sides, or with pictures of celebrities, sceneries, themes, and scenes, printed with defined texts, quotes or ideas. The paper may also be used by children or adults for coloring and accordingly pictures, charts, lines, graphs may be provided on the paper to color. In case the paper is used as a magic/chemically active paper, it may be treated with certain chemicals. The magic paper may include invisible coloring pictures with a combination of water or any other fluid. The invisibly colored pictures may act as a ‘magical’ element while they react with the disposed chemicals. In an embodiment, the paper may be a digital paper or an interactive paper which may be employed for writing with the help of a digital pen.


In embodiments, the dispenser may be used to hold paper made for sticking or pasting purposes. In such a case, the paper may be provided with an adhesive material either on the whole area, a predetermined area or edge(s) of the paper only. The adhesive paper wound around a core, or inserted into the core may create a vertical or horizontal dispensing system determined by the orientation of the paper roll kit. In embodiments, the kit may be placed, attached or adhered to any surface in a vertical orientation creating a vertical dispensing system or in a horizontal orientation creating a horizontal dispensing system. The adhesive paper may be configured in a roll wound around the core or inserted into the core, or the adhesive paper may be configured in multiple pre-cut or perforated sheets wound around the core or inserted into the core. In embodiments where a single sheet is wound around the core or inserted into the core, the user may manually or mechanically dispense any length of sheet in vertical or horizontal orientation. In embodiments where precut sheets are wound around the core or inserted into the core or clamshell dispenser, the user may manually or mechanically dispense a single sheet at a time in vertical or horizontal orientation.


The paper may be used for gift wrapping purposes and accordingly it may be provided with aesthetic features and built-in compartment(s) for accessory or utility items. Proper color schemes and themes such as birthday, marriage and the like may be depicted on the paper or dispenser packaging. The paper used may be rough, smooth, colored, perforated, thick, and thin or the like. In an embodiment the paper roll kit may be made of a recyclable material so as to conserve trees by reusing and or recycling the paper, the tube and its' contents. It should be understood by a person ordinarily skilled in the art that the word paper does not limit to the term of paper only as is conventionally used. However, other similar items may also fall within the scope of the term paper without limiting the spirit and scope of the present invention, such as lamination plastic and the like.


In embodiments, the paper may be written with content as suitable for various purposes. The content may be written on either front side or both sides of the paper. Some examples of the content are creative ideas, quotes, thoughts, jokes, instructions, education, wishes and the like. The paper may be used for branding, advertisement or promotional purposes. In such an embodiment, the paper may be provided with ideas that may help in building a brand or adding to an advertisement of a company. For example, the company may advertise its goals and achievements on the paper. The paper may then be cut and distributed as and when required thereby aiding in branding and advertisement. In another embodiment, a manufacturer may provide its contact numbers and address on the back side of the paper, the cap, or the plug. This helps in advertising of the manufacturer. It should be understood by a person ordinarily skilled in the art that several branding and advertising methods of this kind may be employed with the content provided on the paper. Licensed characters or comic articles may be written on the paper. The paper may also be used as coupons such as a meal coupon and the like or as a template for a desired purpose.


In embodiments, the paper may have printed instructions for guiding tourists, for navigating routes; time tables for transportation means such as for trains, buses, airlines; may be sold in a travel-oriented environment, and the like. Likewise, the paper may include printed drawings to form a coloring book, drawing sheet, and the like that may be utilized in various art and other similar competitions. Alternatively, a continuous or perforated roll of paper may be blank to allow the user to use it for multiple purposes.


In embodiments, the size of the paper and clamshell package along with built-in storage compartment(s) such as width, length, depth and other dimensional parameters may also vary in accordance with various embodiments of the present invention depending on requirements and contents. For example, large sized paper may be required for posters, family games, large drawings, pictorial games and the like; and small sized paper may be required for a kid's roll to be used for coloring, portability purposes and the like. In this scenario, marking may be provided in the paper to allow the large sized paper to be foldable or rewound after retrieving it from the paper roll kit to form it as a book or other similar item. The folded or rewound paper may be inserted inside the hollow core for storage and or protection from damage or future use. (The hollow space of the wound paper roll may also vary and accordingly the core may be required to be compatible to the required hollow space of the paper roll.) The diameter of the core may also be fixed based on selection of utility elements to be stored inside the core as will be described herein.


In embodiments, the core may be extendible and may be resized according to the dimensions of the paper which is wound around the core. For example, if the width of the paper is 15 centimeters while the width of the core is 25 centimeters, the extra 10 centimeters of length may be overlapped around the outside core. Conversely the overlapped section may be unwound and used as a writing surface for paper dispensed from the paper roll. Conventional folding or rolling arrangements may be employed to achieve this objective such as through foldable substrate that is flexible enough to wrap around the roll yet rigid enough to extend and serve as a writing surface. It should be understood that at several instances the core may be permanently or temporarily mounted to the rigid substrate. It should be further understood that this is done merely for descriptive purposes without limiting the spirit and scope of the present invention. In this configuration the paper roll with or without a center core may also be stored in a tube or clamshell dispenser so it may spin on axis without moving around the outside core or clamshell package. The inside core and clamshell may also be used as a storage facility for writing instruments and the like. In multiple configurations the paper roll may be replaced in order to continue use of the core or clamshell dispenser.


In embodiments, the core may be extended or retracted telescopically to adjust to and securely hold various widths of the paper. In other embodiments, the core or clamshell may be any fixed length to accommodate various paper widths. For example a tube or dispenser that includes a roll of three inches, may be used for holding paper suitable for recording note reminders, a tube or dispenser that includes a roll of 6 inches may be suitable for holding even wider paper for more detailed note taking and convenient travel, and a tube or dispenser that includes a twelve inch roll may be used in a paper roll kit for holding larger width paper suited for attachment to and display on an easel or any other use. It should be understood that this is done merely for descriptive purposes without limiting the spirit and scope of the present invention. The length of the core and paper wound around the core or placed inside the dispenser may be configured in an infinite number of lengths for various purposes including but not limited to all described herein.


In embodiments, the inner core or roll may be inserted into a preformed base or preformed dispenser as a means of holding various widths of paper or rolled materials with various lengths of paper or materials in place. The element may be made out of cardboard, plastic, wood, metal, or some other type of material. It may lock into place through a mechanism including an interlocking, clipping or any other mechanism. In other embodiments, as a means to hold the paper roll in a particular orientation within the paper roll kit, the paper alone or the paper around the inner core may be received in the receiving element, 600, of the bottom cap. In embodiments, an adjustable ridge attached to the inner core may positioned along the axis of the core perpendicular to the axis and set at a specified distance suitable for holding a particular width of paper on the core. The ridge may be locked into place, may rest at the base of the receiving element, 600, or may be fastened or adhered to the core through a mechanism including an interlocking, clipping or any other mechanism. The ridge may be made of cardboard, plastic, wood, metal, or some other type of material. In embodiments it may be fixed to the core or formed as a protrusion of the core, and in other embodiments it may be movable and separate from the core.


In embodiments, the core may be made of cardboard, plastic, wood, metal, bio-degradable material, or some other type of material. The material of the mounting or structure designed to hold the roll in place, while still allowing it to spin freely does not limit the spirit and scope of the present invention. Further, in accordance to other embodiments, the paper may be self wound without any requirement of all or part of the core or mounting.


In embodiments, the assembly of the core and the wound paper or roll may be closed using the caps or contained inside the dispenser. The caps are fitted on the sides of the core thereby closing the whole assembly, while the dispenser with a storage element allows for the roll or be dispensed while still providing access to the utility elements either by removing the cap or accessing the elements via a separate compartment without needing to open dispenser and remove the roll. The assembly hereinafter may refer to the core along with the wound paper roll. It should be understood that only one cap may be used in accordance with an embodiment of the present invention while the other side remains closed or attached permanently to a surface and the closing forms a part of the core to provide a storage facility for utility items. The caps may also be referred to as end caps in this disclosure for descriptive purposes without limiting the spirit and scope of the present invention. One or both end caps may preferably be removable and attached to the core by threading arrangements, close fitting or any other similar arrangements. In addition to keeping the contents of the tube inside, the end caps help in protecting the inside paper rolls and core at the sides and corners while the clamshell dispenser protects the entire roll and its contents. End caps may also be used for decorative purposes or as a way of communicating a theme or message to consumers via design, content, graphics or other means. Therefore, the corners, ends or sides of the papers which are usually torn and damaged in unprotected conventional paper rolls may be protected with the help of embodiments of the present disclosure.


In embodiments, the diameter of the end caps may range in such a way that the end caps completely fit the core diameter or inside the clamshell dispenser. However, in other embodiments, the diameter of the end caps may be increased to an extent that the end caps fit the core diameter as well as the wound paper roll diameter. Further, the diameter of the end caps may also vary depending on the requirement of protection of the paper. For, example, in an embodiment, the diameter of one of the end caps may fit half the assembly. Therefore, the two end caps together protect the whole end or the paper and contents thereby avoiding any scratches or damage to the paper or the possibility of the contents falling out of the inside core. Further, the paper roll kit may be used as an easel or convenient dispenser by mounting the outside tube or container to a wall, door, refrigerator door, window or glass, or the like using an attachable magnet, repositionable or other type of glue or adhesive, permanent adhesive, reusable adhesive, hook and rope assembly or by suction on a mounted surface, to perform various drawing and coloring operations.


Referring to FIG. 20A and FIG. 20B, the clamshell dispenser is designed in such a way so no tape, glue, suction cup, or other securing elements are needed due to the novel clamshell design and inclusion of formed undercuts that enable the clamshell dispenser with or without a built-in storage facility to be snapped in or locked into a writing board made of a rigid or flexible substrate. In FIG. 20A, the clamshell dispenser 2002 is shown separate from a rigid material 2004 to be used as a writing board. The rigid material 2004 has an opening 2008 sized to receive and secure, either in a temporary or permanent manner, the clamshell dispenser 2002. Elements of the clamshell dispenser 2002 are designed to mate with elements of the rigid material 2004. For example, undercuts 2104, as shown in FIG. 21B, are designed to engage the rigid material 2004 via a protrusion 2010 of the rigid material 2004. As such the tube or clamshell dispenser may be used as a portable easel for coloring, presentations, large easel for games, home schooling and the like. In other embodiments, the core itself could serve as the dispenser by simply affixing a magnetic or self sealing strip to the back of the roll. In an embodiment, the paper roll may be mounted on a desktop dispenser or the clamshell dispenser may have a built-in writing board element or surface that enables users to dispense paper or other material and have a rigid surface to write or work on.


In an embodiment, the paper or roll kit may be further stored in a packaging, such as a box, a bag, a sleeve, and the like that provides a dispensing element or feature.


In embodiments, the hollow space inside the core or built-in feature to the clamshell dispenser may act as a storage facility to store utility elements depending on the requirements. The utility elements may for example be selected out of stationery elements, toys, plastic figures, army men, writing instruments, paint set, eatables like candy and the like, or any other element depending on the requirements and use of the paper.


The tubes or clamshell dispenser used in embodiments described herein may be made from paper, plastic, wood or other substrates. In embodiments, the tubes and or dispensers may be injection molded tubes. In other embodiments, the storage or dispensing tubes or dispenser may be constructed from a paper or plastic sheet to which printing is applied, die cut and folded and secured into the desired shape. In other embodiments the tubes described herein may be substrate formed into the desired shape. A printed insert card may be used in combination with the tube or dispenser to create virtually any desired graphic design, theme, licensed content, image or the like. The utility elements inside the storage tube or clamshell dispenser may be included to coincide with the theme and or used to increase functionality, usefulness or value to user.


In embodiments, the shape of the paper roll kit may be made to look like other objects, such as using a colored conical cap to make the combination of paper roll and cap look like a crayon.


In embodiments, some examples of stationery elements that may be stored in the hollow space of the core may include, without limitation, crayons, pencils, pens, markers, chalk, poster paints, ink stamps, digital pen, finished drawings, stickers, glue, stapler, measuring tape, ruler, compass, protractor, eraser, sharpeners, shape templates, stickers, tapes, adhesives, written notes, sticky notes, decorating supplies, rolled zipper bag, sponges, water container and the like. Further, a complete water coloring system may also be stored inside the hollow space. In such cases, the hollow space may be portioned in accordance to the requirements. For example, the hollow space may be partitioned into several parts in which there may be sections to keep water colors, paint brush, water containers, sponges and other such accessories. Similarly, other such customized hollow spaces may be designed based on the nature of use of the paper. The stationery elements as stated above may be used in cases when the paper is designed to be used for stationery purposes such as by school going children, teachers, business people or the like. Caps and or plugs may be used in the ends of each embodiment as may a clamshell dispenser with one or more compartments for storage of a roll and or other utility elements. A built-in handle may or may not be utilized as a convenient means of transporting the dispenser or to reinforce a clear message of portability to user. The different sections of the tube may be built as one contiguous tube with multiple compartments or in an alternative embodiment two or more individual tubes may be connected using a snap, twist or other means of attaching the individual sections or using a replaceable divider between two or more sections within the outside dispenser or tube.


In embodiments, some examples of food and eatables that may be stored inside the core are but not limited to candies, snacks, beverages, water, juice and the like.


In embodiments, few examples of make-up accessories may include but are not limited to jewelry, bangles, bracelets, comb, hair band, rubber band, ribbon, strings, skin moisturizers, creams, powders, and the like.


It may be understood by a person ordinarily skilled in the art that several other utility elements may also be stored inside the core without limiting the spirit and scope of the present invention. Some more such examples are but not limited to toys, tearing or cutting accessories, first aid kit, travel supplies, games including video games, map games, drawing games, a watch, a calculator, toothpaste, cases, casings, waterproof carrying cases, covering cloth and the like.


In embodiments, the end caps inserted into the center of the outside and or inside tubes in addition to the clamshell dispenser may also serve as a storage facility in which the utility elements as described above may be stored for various purposes. The utility elements and the various purposes have already been described above. However, it should be understood that since the storage capacity of the end caps is relatively smaller than the storage capacity of the outside core, therefore all the utility elements as stated above should fit in the inside core and or end caps. The utility items stored inside the center tube may be accessed by removing the entire outside end cap and or an attached or inserted center plug or cap. The cap may be a flip top, screw cap or removable cap. The paper roll stored inside the tube may be removed by taking off the entire end cap The inner diameter cap, 500, may be plugged, screwed, interlocked or otherwise secured into the entire cap assembly, 501, as seen in FIG. 5. The inner diameter cap, 500, may be rotated to turn the inside tube, 504, and unwind a length of paper to protrude from a slot in the outside tube. In embodiments, the entire cap assembly, 501, may rotate as a means of dispensing paper. In other embodiments, only the inner diameter cap, 500, may rotate as a means of dispensing paper. The lip, 502, of the entire cap assembly may act as a barrier to prevent the paper roll from falling out of the tube. In embodiments, the lip, 502, of the entire cap assembly may be extended to project perpendicular to the plane of the lip in order to secure the cap to the outside tube. In embodiments, the inner diameter cap, 500, may be a screw cap flip top cap, interlocking, clip on or other cap that allows access to the inside core and utility elements while the lip of the cap, 502, remains in place and acts to keep the paper roll in place. While specific dimensions are listed in this FIG. 5, these are for illustrative purposes. In embodiments various dimensions may be used.


In embodiments, the inside core may be inserted into or around a receiving element, 600, in the top or bottom cap as a means of holding the core in place as seen in FIG. 6. In embodiments, the cap, 502, may be inserted around the inside tube or plugged, screwed or otherwise fastened in or around the inside tube. In embodiments, the caps on both ends may be identical to the entire cap assembly, 501. In other embodiments, one cap may be a screw cap without an inner diameter cap, 601, as seen in FIG. 6. In other embodiments, one cap may be identical to 501 while the other is a permanent cap. In addition a built in or secondary hang tab affixed to the end cap may be used in order to provide an additional way of hanging or displaying the entire roll from its hang tab.


In embodiments, the end caps may have built-in recesses and customized designs to store specific utility elements. For example, the end caps may have built-in sharpeners, built-in erasers, toys, and the like all of which may be customized and or molded into a specific design or configuration. A cutting mechanism may also be provided in the end caps which may directly be employed for tearing or cutting purposes. In addition, the clamshell dispenser design may have one or more storage compartments white the clamshell dispenser flanges may have one or more tearing features such as serration, wavy edges, and the like.


In embodiments, the kits such as paper roll FIG. 13 and any display platforms may be provided with hanging arrangements such as clamps, magnets, clips, pins, permanent or removable tape and the like that may cause the kits and the display platforms to be deployable on walls, doors, trees and other similar structures.


In embodiments, the paper roll kits may be used in, purchased or distributed from grocery stores, drug stores, toy stores, art stores, office supply stores, fundraising organizations, restaurants, doctor's office, hotels, and the like. Several marketing and business strategies may be employed for selling kits such as FIG. 2. One such strategy that may be adapted is to provide free gifts and puzzles to win a prize along with customized end caps. The paper roll kits may also be purchased online through websites. The prizes with the end caps may be a good source of attraction to customers.


In embodiments, flexible displays designed for input and output, games coloring, drawing by means of using a limb, finger, pen, crayon, pencil, stylus, or any other instrument may replace the paper in the paper roll kit. In embodiments, the flexible display may roll up to create a tube inside which utility elements may be stored as described herein with or without the use of caps or any combination of caps described herein. In other embodiments flexible materials may be included in the roll kit, such as with embedded sensors or electronics enabling the tracking of movement of writing instrument (either conventional or a digital or “smart pen” that is capable of tracking movement), such as used in digital whiteboard applications. Thus, whether on a flexible display or other flexible material, user actions of writing may be tracked and captured, such as by an associated processor and memory. References to the paper roll kit throughout this disclosure should be understood to possibly include substitution or addition of such flexible displays or other flexible materials for paper in the paper roll kits described herein. Thus, in embodiments, the paper roll kit may be provided with a controlling unit that has a processor and a memory. The controlling unit may be connected to a network. In embodiments, the network may be a LAN, WAN, MAN, Internet and the like. A security facility associated with paper roll kit may facilitate authentication of communication between the external network and the paper roll kit. For example, a user using the paper roll kit as a doodle roll kit may perform certain tasks and submit the tasks in some prize winning competition available on various online portals directly from the platform. The user may then receive a response regarding the competition or any prizes if won directly from the competition organizing authority. An example of websites that may receive such tasks or work may be DOODLEROLL.COM. This embodiment would be built using a known technology of a paper thin, bendable computer screen resembling paper. The purpose is to replicate the physical experience of coloring using utility items such as crayons, markers and the like by using a stylus or fingers and coloring on the interactive computer screen. Options to select predetermined colors, designs, themes, games or other activities would all be loaded in the micro chip processor used to operate the device. All of these features could be down loaded or uploaded from a home page.


In embodiments, the paper roll kit may be integrated with other devices such as with a home printer, a fax machine, a telephonic device and the like. The integration may be performed by the user or the user may also get a customized integrated device according to the needs. The communication with other devices may be performed either through a wired medium or wireless. Accordingly various protocols such as WAP, Bluetooth, RFID and the like may be employed for facilitating the communication.


In embodiments, paper roll kits as described in detail above may find several applications. Some examples of such applications are given below. However, a person ordinarily skilled in the art may understand that various other applications are also possible without limiting the spirit and scope of the present invention.


In embodiments, the paper roll kits may be used for purposes such as painting, drawing, note taking, coloring, wrapping, doodling, tracing, sketching, banners, brainstorming, digital paper applications, decoration applications, placements such as table covering and the like.


In embodiments, the paper roll kits may be used for entertainment purposes, gifts, party favors, promotions, fund raisers and advertising.


In embodiments, the paper roll kits may be employed in restaurants, planes, day care facilities, schools, doctor's offices, business settings, homes, toilets, kitchens and the like places.


In embodiments, the paper roll kit as described by the present invention has several advantages. The paper roll kit saves paper which may be a very costly resource. For example, the user may dispense or pull form the roll and cut a specific amount of required paper and use it for printing purposes rather than using a predetermined size sheet which is most commercially readily available in virtually all configurations, sizes and retail locations selling paper related products. This process can only be achieved when dispensing paper in roll form which makes the current invention unlike any known means of dispensing paper. However, in conventional modes the user uses only the standard sheets for printing irrespective of the data that needs to be printed. Therefore, wastage of the paper may be avoided. Further, the user may purchase customized kits for various purposes such as for arts and crafts, doodling, kitchen and the like. The user may also get related accessories along with the kits, most of which are readily available at many stationary, office supply, department stores, toy stores and the like. Another advantage is the utilization of the space inside the core which otherwise may remain unused in the conventional applications. The space inside the end caps or utility storage compartments built-in to the clamshell dispenser may also be utilized thereby making more use of the available space in addition to or in lieu of the inside tube. The clamshell design provides a simple platform for a replacement roll or utility elements to be replaced once the original contents are consumed by the user.


In embodiments, the paper roll kits may be purchased in the market for various applications by their specific names that reflect the nature of use. For example, a paper roll kit for doodling may be termed as doodle roll kit and a paper roll kit for painting may be termed as painting roll kit. However, the term of a particular paper roll kit does not limit the area of its applications and it may be used for any desired purposes as seems fit to the user.


In embodiments, the hollow space inside the core may be divided into two separate compartments equal or unequal in size by inserting a barrier in the hollow tube perpendicular to the axis of the core. The addition of the barrier will result in two separate, compartments for storage of various elements. Separate compartments can also be made by inserting a cylindrical object into the tube, thus providing the option to choose the desired space in each side(s) of the tube. This option allows for storage of different size utility items. For example, the hollow space inside a paper roll kit for doodling may be divided into two separate compartments where elements such as crayons, markers, and scissors or toys such as army men and a slinky are stored in one side of the kit and dispensable or non-dispensable paper is stored in the other side as described further in FIG. 2. The paper in the paper compartment or the cap on one side of the roll may extend to shield the compartment such that the elements in the compartment are not visible, thereby creating a “secret compartment” to prevent the identification of elements if desired


In embodiments, an element suitable for tearing paper may be attached, fastened or built-in to the paper roll kit for the purpose of tearing any length of paper from the roll as described in FIG. 3. The tearing element may be constructed as part of the paper roll kit or fastened, attached or adhered to the paper roll kit with an adhesive including glue, tape or any other adhesive or it may be fastened or attached to the paper roll kit through a mechanism including an interlocking, clipping, or any other mechanism. The tearing element may be made of cardboard, plastic, wood, metal, or some other type of material. In embodiments, the element suitable for tearing paper will create friction or resistance against the paper to prevent an over abundance of paper from being removed from the paper roll kit at one time as well as make it easier for the user to tear off paper. The clamshell dispenser may be made in any length thus allowing for any size paper or other roll to be torn against one or two of flanges by which paper or roll is dispensed between.


In embodiments, the dispensable or non-dispensable paper used with the paper roll kit may be used for sticking or pasting purposes. In such a case, the paper may be provided with an adhesive material either on the whole area or on the corners or edges of the paper only. The paper may be used for the purpose of taking short notes and adhering the note to another object for the purposes of creating a reminder or the paper may be used in any other setting including a business meeting where a larger piece of paper is removed and adhered to an object such as an easel, wall, board or door for use in recording notes, images or ideas. In embodiments, the hollow space inside the core or in the storage compartments built-in to the clamshell design may contain elements such as highlighters, markers, pens, pencils, paper clips, binder clips, a stapler, staples, rubber bands or any other element. In embodiments, the paper roll kit may be equipped with an element suitable for tearing various lengths of adhesive paper. In embodiments, the hollow space inside the core may be divided into two separate compartments equal or unequal in size by inserting a barrier in the hollow tube perpendicular to the axis of the core and one compartment may contain dispensable or non-dispensable adhesive paper used for sticking or pasting purposes or any other paper and the other compartment may contain elements such as highlighters, markers, pens, pencils, paper clips, binder clips, a stapler, staples, rubber bands or any other element and the paper roll kit may or may not be equipped with an element suitable for tearing various lengths of adhesive or non adhesive paper.


In embodiments, a hollow tube, as described in FIG. 4, may be inserted into the hollow space inside the core for holding elements including crayons, pencils, markers, erasers, ink or paints, or other elements of appropriate size.

In embodiments, and referring to FIG. 17A (side view), FIG. 17B (face view with open utility compartment), and FIG. 17C (face view with closed utility compartment), the paper roll kit may be packaged in a clamshell dispenser where additional items for use with or without the paper roll kit may be included in the packaging. In FIG. 17A, FIG. 17B, and FIG. 17C, the packaging for the paper roll kit includes one or more storage compartments 1702 for utility items such as crayons, however, this space could just as easily house a snack or some other item. This compartment 1702 may vary in size and shape to accommodate various items. In embodiments, a circular or non- circular compartment 1704 may be disposed in the packaging so that the paper roll may be held in place and unwound and dispensed from the packaging. This compartment 1704 may vary in size and shape to accommodate variously sized rolls.


The clamshell packaging may include an attachment facility, such as removable tape or double-sided tape, for adhering the packaging and its contents to a surface, such as a wall, easel, desk, refrigerator, or the like. In embodiments, the clamshell may have holes by which the dispenser may be mounted or hung from an easel or other areas in order to suspend the clamshell so the roll material may be dispensed. In embodiments, the packaging can be attached such that paper is pulled from the packaging to the desired length vertically up, vertically down, or horizontally in any direction.


In embodiments where the packaging is attached to an easel, this configuration allows users to write on a roll continuously and keep pulling paper up and over the top of the easel or keep pulling the paper down and allowing it to collect below the easel. In embodiments where the paper roll comprises adhesive, or sticky, paper, the paper may stay flat on the easel while writing or can be clipped in place if the paper is not adhesive. In embodiments, the easel may comprise a dry erase surface.


In embodiments and according to FIG. 18 or FIG. 20A or FIG. 20B, the clamshell dispenser packaging may include an insert card 1808 inside the package which also serves as the label. This card may have one or two headers suspended from the flanges of the dispenser. The headers may be suspended at a desired length and formed in any shape, height, design or form. In an embodiment, when the headers are removed, the dispenser package no longer needs to be opened and the paper may be pulled directly from the clamshell without opening the clamshell. The insert card may serve as graphic packaging for the top and bottom of the package, end caps, and instruction card and may be secured inside the package by built in formed snaps. In embodiments, messages may be embossed into the package reducing the need for additional exterior or interior labels in some cases.


In embodiments, the clamshell dispenser may be thermoformed from appropriate material to form a dispenser with one or more compartments with built-in storage for items and paper, wherein the clamshell packaging may have one or two serrated, straight, or wavy edges, or different patterns used for the top and or bottom flange for easy tearing. The thermoforming process starts with blank thermoplastic material that is processed so as to form all the necessary functional and engagement features in a continuous operation. There are interlocking features that are formed into the clamshell dispenser that are male on one half and female on the other half These engage with an interference fit to provide a tight fit of the opposed sides of the clamshell dispenser along the length of the engagement. The material at the hinge point of the clamshell dispenser enables the two halves of the clamshell dispenser to fit together and function for its intended purpose(s)


A process for manufacturing the clamshell dispenser commences with a die-cut or otherwise formed shape punched from thermoplastic material appropriate to the thermoforming process and of a close approximation to the overall dimension of the clamshell dispenser. The thermoplastic material be clamped between an upper clamping fixture and a mold cavity and heat may soften the material to the point where it is formable but before it reaches the point of uncontrolled deformation. The heat deforms the center of the thermoplastic shape and air pressure, positive above the sheet and negative below, may begin to elongate the material into the cavity of the mold. The fine detail of the clamshell dispenser may be created in the cavity of the mold but may be assisted by a rigid or compliant insert tool with additional heat, mechanical pressure, air pressure and/or vacuum pressure to apply high resolution detail including additional features such as interlocking features or to apply modifications in depth or configuration of the roll or utility item compartments. Using various interchangeable insert tools, it should be apparent that many different variations of the clamshell dispenser are possible to accommodate various uses and various dimensions of rolls and dimensions and quantity of utility items without having to modify the mold. Of course, for an overall differently dimensioned clamshell dispenser, a different mold may be required. For example, and referring now to FIG. 21, wherein FIG. 21A shows an embodiment of a 4 inch clamshell dispenser in a laid open view, FIG. 21B shows the closed embodiment in a face view, and FIG. 21C shows the closed embodiment in a side view, embodiments of the clamshell dispenser may have undercuts 2104 built into the outside package design which allow for the clamshell to be snapped/locked into a writing board or other surfaces without the need for tape, glue, clasps, welding, or the like. Further, the clamshell is designed so paper can be dispensed and torn off by tearing paper either up or down and still not need to reopen the clamshell due to the finger holds 2108 in the extended flange. Finger holes can be formed or die cut into clamshell to aid in opening compartments or guiding paper through or in between flanges. Flanges can be designed in a way such that one of the flanges is notched, curved or designed in such a way that if the paper is torn the paper can still be dispensed because the user still has access to pulling out the paper without opening the package. Furthermore, if an adhesive or sticky paper is used in the clamshell, by leaving one flange a little shorter or creating a notch of some sort to help guide the paper out, the problem of the paper sticking to surface of the sticky side flange is reduced.


Additionally, small nicks 2110 may remain attached in a few places on the utility compartment cover 2112. Nicks 2110 are very small pieces of plastic that are left uncut when the clamshell is die-cut. Thus, no fastener over the utility compartment cover 2112 is needed to hold it in place. The nicks 2110 allow the lid to stay closed until the first time the package is opened. Different flanges 2114, 2118 are possible in a single clamshell dispenser. For example, flange 2114 has a straight edge while flange 2118 has a wavy edge. It should be understood that any pattern of flange edge is possible, such as serrated and the like. Also, the top and or bottom flanges may be shorter than the other so when a piece of paper is torn off against the longer flange, paper may still be pulled out without opening the package. In embodiments, a ruler may be embossed, drawn, painted or adhered to a surface of the dispenser such as at the flange or at the hinge point.


In embodiments, once the paper or roll is dispensed from the clamshell and torn against the top or bottom flange with or with a serrated, wavy, or straight edge, the paper can be guided out of the clamshell past the flanges using the built in ovals 2108 in the top flanges thus eliminating the need to open the clamshell to pull out an additional piece or paper.


In embodiments of the clamshell dispenser packaging may include protruding male undercut features 2104 which allow the clamshell to be snapped in or affixed to a separate writing board or rigid substrate without the need for glue, tape, magnets, adhesives, sonic welding or other way separate components may be attached. Once attached, the board can be easily removed or put back on by simply snapping it in. In embodiments, snaps or button locks 2120, as well as undercuts, may be included for better in-store security and reduced likelihood of opening in store. In embodiments, a hang hole 1804 allows presenting the clamshell dispenser to merchandise on peg, clipstrip, or the like.


In embodiments, the clamshell packaging for the paper roll may have an integral handle 1910, such as an opening formed in the packaging as in FIG. 19A or a molded piece extending from an edge of the clamshell. In embodiments, the handle may be detachable, made of different shapes, designed, dimensions. The handle may be a molded semi-circle or semi-rectangle that clips, snaps onto, or adheres to the clamshell packaging. In the embodiment shown in FIG. 19A, a 24 inch clamshell packaging includes one or more button locks 1902 to secure the two halves of the clamshell to each other, a built-in storage compartment 1904 for holding utility items, a finger relief 1908 for enabling easy access to the compartment 1904, a handle 1910 for transporting the dispenser, a roll compartment 1912 for holding a roll of material to be dispensed, a flange 1914 for dispensing the paper and, optionally, tearing the paper, and a stiffening rib 1918 to provide additional rigidity to reduce the likelihood of crushing and to improve tearing. In embodiments, the ribs may 1918 be used on the sides of the compartments 19041912 as well to improve rigidity as well as any other surface on the clamshell. Another version of the rib 2202 is shown in FIG. 22. FIG. 19B shows a face view of the 24 inch clamshell packaging. FIG. 19C shows the clamshell dispenser in use with a roll of writing material being dispensed from the compartment 1912.


Referring now to FIG. 23A, FIG. 23B, and FIG. 23C, an embodiment of a 4 inch clamshell dispenser is shown in a front view (FIG. 23A), laid open view (FIG. 23B), and a face view (FIG. 23C). Another 4 inch clamshell dispenser is shown in FIG. 24, now with variations of a hang hole 2402, 2404.


Referring now to FIG. 25A and FIG. 25B, an embodiment of one-piece clamshell dispenser is shown in a laid open view (FIG. 25A) and a closed view (FIG. 25B).


Referring now to FIG. 26A-F, embodiments of a clamshell dispenser with a built-in easel are shown where the dispenser folds to reveal a surface useful as an easel. FIG. 26A shows a top-down view of the laid open dispenser, FIG. 26B shows an end version of the laid open dispenser, FIG. 26C shows a side view of the closed and folded version of the dispenser with easel revealed, FIG. 26D shows a face view of the closed and folded version of the dispenser with easel revealed. FIG. 26E shows a front view of the closed dispenser, and FIG. 26F shows a side view of the closed dispenser.


In embodiments, the clamshell dispenser may be formed from two separate pieces forming the front and back of the dispenser instead of a single piece that folds to engage the two sides of the dispenser. One flip-top version is shown in FIG. 27A in a side view of the two separate pieces and FIG. 27B in a front view of the joined pieces. The fronts of the compartments may flip open to reveal their contents. Optional hinges 2702, 2704 transform this two-piece embodiment to a one-piece embodiment. Additionally, hinges on any of the sides may transform this two-piece embodiment to a one-piece embodiment. In this embodiment, printed or plain paper, dry erase material, playing cards, flash cards, or anything else could be placed in one of the compartments. The other compartment could be used for any utility items like crayons, markers, dice, stamps, etc. In addition, the flat surface could be used to write on as well. A slot could be made in the larger or smaller flat surface for paper to be dispensed from. Instead of paper being in a roll, it could be folded in accordion style or some other fashion so it could be pulled from a slot. Another two-piece clamshell design is shown in FIG. 30.


Referring now to FIG. 28, a front view (FIG. 28A), side view (FIG. 28B), and back view (FIG. 28C) of a 4 inch clamshell dispenser is shown.


Referring now to FIG. 29, a front view (FIG. 29A) and face view (FIG. 29B) of a 6 inch clamshell dispenser is shown.



FIG. 31A shows the clamshell dispenser in action dispensing paper and crayons and FIG. 31B shows paper being torn along an edge.


In embodiments, using certain angles of curvature of the roll compartment of the clamshell dispenser as it meets the space just prior to the dispensing channel between the flanges enables the roll to dispense easier. A curvature at a 90% angle will be more difficult to dispense than if the radius is closer to 45%.


In embodiments, using button locks, snaps, hinges, channels, or other connection features, a gap can be created between the top and bottom flange. The distance between flanges also can play a factor in how easy or difficult it is for paper to be dispensed. Further, these connection features will not disconnect without externally applied force and will thus serve to keep the clamshell dispenser closes, such as in a retail environment.


It should be understood that any of the features or benefits described with respect to one size of clamshell dispenser may be possible with any other size of clamshell dispenser.


While the invention has been disclosed in connection with the preferred embodiments shown and described in detail, various modifications and improvements thereon will become readily apparent to those skilled in the art. Accordingly, the spirit and scope of the present invention is not to be limited by the foregoing examples, but is to be understood in the broadest sense allowable by law.
