BACKGROUND

Paper products and other paper product have been manufactured to be stored and dispensed in a rolled form. Typically, disposable paper products are wrapped in a roll form around a tube. In this way, depending on the amount of product wrapped around the roll, the various rolls may come in a variety of sizes, including length and circumference, depending on the paper product being dispensed, such as toilet paper, paper towels, or the like. Rolls allow for a compact packaging of long lengths of the paper products and dispensing of the same. However, the rolled design does not provide protection to the paper product on the roll. The material, especially the outer layer, is exposed to the elements, including water, which may hinder the performance of the paper product. As such, there exists a need for developing a paper product dispenser that provides adequate protection to the paper product.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

The present inventions are described in the following by referring to drawings of examples of how the inventions can be made and used. In these drawings, reference characters are used throughout to indicate like or corresponding parts. The embodiments shown are described herein are exemplary. Many details that are well known in the art are neither shown nor described.

Embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to elements throughout. Where possible, any terms expressed in the singular form herein are meant to also include the plural form and vice versa, unless explicitly stated otherwise. Also, as used herein, the term “a” and/or “an” shall mean “one or more,” even though the phrase “one or more” is also used herein. Furthermore, when it is said herein that something is “based on” something else, it may be based on one or more other things as well. In other words, unless expressly indicated otherwise, as used herein “based on” means “based at least in part on” or “based at least partially on.” Furthermore, the term paper products may include one or more other types of sheet material, such as cloth, steal, cardboard, or the like.

While the foregoing disclosure discusses illustrative embodiments, it should be noted that various changes and modifications could be made herein without departing from the scope of the described aspects and/or embodiments as defined by the appended claims. Furthermore, although elements of the described aspects and/or embodiments may be described or claimed in the singular, the plural is contemplated unless limitation to the singular is explicitly stated. Additionally, all or a portion of any embodiment may be utilized with all or a portion of any other embodiment, unless stated otherwise.

Embodiments of the invention relate to methods and apparatuses for protecting and dispensing a roll of sheeted material, namely disposable paper product material.

The invention may hold any type of rolled paper product where the paper product is formed in a cylindrical roll or other shape. Typically, the roll of paper product comprises a core (e.g. a cardboard roll) upon which the paper product is wound. The core may be a cylinder with two open ends. The paper product may consist of, but is not limited to, paper products, fabric, sheet metal, sheet composites, other sheet type material, and the like. For simplicity, herein the term “paper product” may include one or more of the above paper products. The roll of paper product may have a large diameter when full and a continually decreasing diameter upon use of the paper product. As such, as material is dispensed from the roll of paper product, the diameter of the roll reduces. Additionally, the roll of paper product may also have a given height that remains consistent regardless of the capacity of the roll. However, the height may change depending on the type of paper product on the roll, such as paper towels, toilet paper, napkins, drawing paper, cardboard, steel rolls, or the like.

FIG. 1A illustrates a prospective view of the apparatus 100. The apparatus includes a semi-flexible sheet 102. The semi-flexible sheet 102 is generally made of a semi-ridged plastic type material. In some embodiments, the semi-flexible sheet 201 may be made with a plurality of materials, such as plastic, composite material, metal, or combination thereof. In some embodiments, when the semi-flexible sheet 102 is made of plastic, the plastic may be a polyvinyl chloride.

The semi-flexible sheet 102 comprises a leading end 106, a distal end 108, a first side edge 110, and a second side edge 112. The semi-flexible sheet 102 is manufactured such that it is capable of being radially collapsible into a cylindrical shape or other shape over a roll of paper product 200. As illustrated, the roll of paper product 200 includes an inner core 204. In this way, the semi-flexible sheet 102 provides a spring like force upon radially collapsing that provides an inward tension onto the roll of paper product 200. Thus, completely surrounding the sides of the paper product and providing protection to the paper products. When the semi-flexible sheet 102 is radially collapsed into a cylindrical shape, the leading end 106 overlays the distal end 108 and a portion of the semi-flexible sheet 102. The leading end 106, the distal end 108, and the portion of the semi-flexible sheet 102 form a gap or slit longitudinally along the edge, that allows a single sheet or a portion of a single sheet of the paper product 202 to be positioned between the leading end and the distal end 108. In this way, allowing the paper product to be dispended from the apparatus.

In some embodiments, the corners formed by the first side edge 110, the second side edge 112, the leading end 106, and the distal end 108 may be rounded.

FIG. 1B illustrates a side view of the apparatus 101. As illustrated in FIG. 1B, the semi-flexible sheet 102 with a leading end 106, a distal end 108, a first side edge 110, and a second side edge 112 is illustrated. The semi-flexible sheet 102, as shown, is radially collapsed onto a roll of paper product 200. As illustrated, the semi-flexible sheet 102 is completely surrounding the sides of the paper product and providing protection to the paper products. As illustrated in FIG. 1B, when the semi-flexible sheet 102 is radially collapsed into a cylindrical shape, the leading end 106 overlays the distal end 108 and a portion of the semi-flexible sheet 102. The leading end 106, the distal end 108, and the portion of the semi-flexible sheet 102 form a gap or slit longitudinally along the edge, that allows a single sheet or a portion of a single sheet of the paper product 202 to be positioned between the leading end and the distal end 108. In this way, allowing the paper product to be dispended from the apparatus.

FIG. 1C illustrates a top view of the apparatus 103. As illustrated in FIG. 1C the semi-flexible sheet 102 is formed so that it radially collapses to form a cylindrical shape around the paper product 200 with inner core 204. As such, the first side edge 110 and the second side edge 112 forming a shape around the paper product 200. When the semi-flexible sheet 102 is radially collapsed into a cylindrical shape, the leading end 106 overlays the distal end 108 and a portion of the semi-flexible sheet 102. The leading end 106, the distal end 108, and the portion of the semi-flexible sheet 102 form a gap or slit longitudinally along the edge, that allows a single sheet or a portion of a single sheet of the paper product 202 to be positioned between the leading end and the distal end 108. As illustrated in FIG. 1C the top of the paper product 200 and inner core 204 are exposed. As such, the apparatus is covering the sides of the paper product 200 in this embodiment.

An operator may manipulate the semi-flexible sheet 102 to place a roll of paper product 200 within the cylindrical shape of the semi-flexible sheet 102. In some embodiments, the semi-flexible sheet 102 may collapse onto the roll of sheeted material or paper product 200 such that an inner surface of the cylindrical shape formed by the semi-flexible sheet 102 exerts pressure on the roll of paper product 200. In some embodiments, the inner diameter of the cylindrical shape formed by the semi-flexible sheet 102 when fully radially collapsed is larger than the diameter of the inner core 204 of the roll of the paper product 200.

In some embodiments, the semi-flexible sheet 102 may be designed based on the roll of paper product 200. As such, the measurements of the semi-flexible sheet 102 may be based on the roll of paper products 200 the semi-flexible sheet 102 is being designed to protect. In other embodiments, the material used to make the semi-flexible sheet 102 may be selected based on the roll of paper products 200 the semi-flexible sheet 102 is being designed to protect.

As such, in some embodiments, the overall width and length of the semi-flexible sheet 102 may be determined based on the type of roll being protected by the apparatus. As an example. An apparatus protecting toilet paper may be smaller in width than an apparatus protecting paper towels, steel sheets, drawing paper, or the like

In some embodiments, the width of the semi-flexible sheet 102 or the measurement of the leading end 106, may be equal to or greater than the height of the roll of paper product 200. As such, the semi-flexible sheet 102 may cover the entire outer surface area of the paper product. In this way, the measurement of the leading end 106 of the semi-flexible sheet 102 may be designed based on the height of the roll of paper product 200. In some embodiments, the measurement of the leading end 106 may be equal to the height of the roll of paper product 200. In other embodiments, the length of the leading end 106 may be greater than the height of the roll of paper product 200 to provide protection to the roll of paper product 200 and/or allow for additional features as will be explained herein. In some embodiments, the leading end 106 may be a length equal to the length of the distal end 108 of the semi-flexible sheet 102. In other embodiments, the distal end 108 of the semi-flexible sheet 102 may be shorter than the leading end 106.

In some embodiments, the length of the semi-flexible sheet 102 or the measurement of the first side edge 110 or second side edge 112 between the leading end 106 and the distal end 108 may also be determined based on the circumference of the roll of paper product. A larger roll of material or a thicker material may require a larger semi-flexible sheet 102. The semi-flexible sheet 102 is designed to cover the entire outside portion of paper product and overlap itself. As such, the length of the semi-flexible sheet 102 may be greater than the circumference of the roll of paper product at its capacity. As such the distance between the leading end 106 and distal end 108 may be designed to create a given diameter of the cylindrical shape around a roll of paper product 200 and include an overlap of material. For example, where a roll of paper product 200 has a given circumference, the distance between the leading end and the distal end 108 may be designed such that the circumference of the cylindrical shape formed by the semi-flexible sheet 102 when collapsed is greater than the circumference of the roll of paper product 200.

Furthermore, the radial collapsibility of the semi-flexible sheet 102 may be determined based on the roll of paper product 200. In this way, the semi-flexible sheet 102 may have a length long enough to overlap itself upon radial compression around a roll. Furthermore, the semi-flexible sheet 102 may, upon complete compression have an inner diameter that is slightly larger than the outer diameter of the core 204 of the roll of paper product 200. As such, as paper product 202 is removed from the roll of paper product 200 and the diameter of the cylindrical shape formed by the radial compression of the semi-flexible sheet 102 is reduce, the inner surface will apply at least an amount force or pressure on the roll of paper product 200, even after all of the paper product or sheet material has been dispensed.

In some embodiment, as disclosed above, while a variety of materials such as plastics, metals, fibers, polymers, or composites may be used to make the semi-flexible sheet 102, other factors associated with the material the apparatus is surrounding may play a role in determining the material used to create the semi-flexible sheet 102. Such factors might include protection requirements for the paper product 202, a rigidity of the semi-flexible sheet 102 required, an applied pressure requirement for the roll of paper product 200, whether an attachment mechanism is included, whether a gripping edge is included, and/or the like. In some embodiment.

In some embodiments, one factor to consider in selecting the material used for the semi-flexible sheet 102 is the type of product that the semi-flexible sheet 102 will protect. As such, the semi-flexible sheet 102 may be required to comprise water protection properties, dirt protection properties, be constructed to protect from excess force, temperature protection, element protection, or the like. In some embodiments, materials may be selected based on their ability to protect the paper product 202. For example, some materials must be protected from water damage. Materials such as plastics have a high ability to repel water. Other protections may include protection from dirt or other staining elements, protection from radiation such as ultraviolet (UV) light, protection from abrasion or other mechanical wear, and protection from punctures or cutting.

In some embodiments, one factor to consider in selecting the material may be the rigidity of the semi-flexible sheet 102 required. The rigidity of the material may be based on the modulus of elasticity of the material, the sheet strength of the material, and the like. These factors will be discussed to influence the design of the semi-flexible sheet 102 and the material from which the semi-flexible sheet 102 is manufactured.

In some embodiments, one factor to consider in selecting the material may be the applied pressure requirement for the roll of paper product 200. In this way, when the paper product 202 is rolled up into the roll of paper product 200, the material may apply a force causing the paper product 202 to maintain its shape and prevent it from unwinding. This force is applied radially across the entire roll evenly based on the spring like nature of the semi-flexible sheet 102. A greater presser may be required to prevent rolls of steel or other products from unwinding relative to disposable paper rolls.

Furthermore, the semi-flexible sheet 102 may include a pressure requirement that allows material from the roll to be removed through the slit or gap created. In some embodiments, the applied pressure may be such that there is a resistance between the gap, but still allows paper product 202 to be removed through the gap.

FIG. 2A illustrates a front view of the apparatus with clips 105, in accordance with one embodiment of the present invention. As illustrated in FIG. 2A, a semi-flexible sheet 102 is illustrated comprising a leading end 106, a first side edge 110, and a second side edge 112. The semi-flexible sheet 102 further comprises attachment mechanisms 124. The first attachment mechanism 124 is connected to the first side edge 110 of the semi-flexible sheet 102 and located proximate to the leading end 106. The second attachment mechanism 124 is connected to the second side edge 112 and located proximate to the leading end 106. In some embodiments, the attachments mechanisms 124 may be J shaped clips that form a gap between the clips and a surface of the semi-flexible sheet 102. A portion of the semi-flexible sheet 102 may be positioned into the gap between the clip and semi-flexible sheet 102 such that the clip applies pressure to a portion of the semi-flexible sheet 102 to inhibit movement of the semi-flexible sheet 102 but allow repositioning of the semi-flexible-sheet with sufficient force. Furthermore, allowing a user to remove one or more sheets of the paper product from the apparatus without the apparatus loosing tension around the paper product.

FIG. 2B is an expanded end view of the clips of the apparatus 107, in accordance with one embodiment of the present invention. FIG. 2B illustrates the attachment mechanism 124 attaching to a portion of the semi-flexible sheet 102B. As such, the leading end 106 with the attachment mechanism 124 and a portion of the semi-flexible sheet 102A overlaps the distal end 108 and a portion of the semi-flexible sheet 102B located proximate to the distal end 108. In this way, the attachment mechanism 124 forms a clip around the semi-flexible sheet 102B, securing the semi-flexible sheet 102B in a radially collapsed position about itself. Furthermore, a gap 145 is formed between the clipped semi-flexible sheet 102B and the semi-flexible sheet 102A such that paper product may be dispensed through the gap 145 created.

FIG. 2C illustrates a perspective view of an embodiment of the apparatus 109, in accordance with one embodiment of the present invention. As illustrated in FIG. 2C a semi-flexible sheet 102 comprises a leading end 106 a distal end 108, a first side edge 110, and a second side edge 112. The semi-flexible sheet 102 is manufactured such that it is capable of being radially collapsible into a cylindrical shape or other shape over a roll of paper product 200. As illustrated, the roll of paper product 200 includes an inner core 204 and a single sheet coming from the roll of paper product 202.

In some embodiments, the semi-flexible sheet 102 includes one or more end covers 120 and an attachment mechanism 124. The semi-flexible sheet 102 may include multiple end covers 120, where the end covers 120 are attached to and extend perpendicularly from the first side edge 110 and the second side edge 112. The end covers 120 are located such that they cover at least a portion of the roll of paper product 220. The end covers 120 comprise angled spaces 122 between the end covers 120 that create notches and allow semi-flexible sheet 102 to be collapsed into a cylindrical shape without causing the end covers 120 to bind. When the semi-flexible sheet 102 is radially collapsed into a spherical shape, the notches 122 of the end cover 120 are reduced in size until the inside edges of the angled spaces 122 are in contact with one another either end-to-end or overlapping. Thus, the angled spaces 122 provide a completely closed area when the semi-flexible sheet 102 is radially collapsed into the cylindrical shape around the roll of paper products 200.

In some embodiments, the semi-flexible sheet 102 comprises one or more attachment mechanisms 124. These attachment mechanisms 124 create a clip or hinge configured in a J shape. The attachment mechanism 124, in this embodiment, extends from the end cover 120 along the leading edge and create the J shaped clip. The attachment mechanisms 124 are utilized to attach to a portion of the semi-flexible sheet 102 and/or one or more end covers 120 at a point along the semi-flexible sheet 102 away from the leading end 106. As such, when the semi-flexible sheet 102 is radially collapsed into the cylindrical object, the attachment mechanism 124 may be releasably attached to another portion of the semi-flexible sheet or the end cover 120. As the roll of paper product 200 is dispensed, the attachment mechanisms 124 when releasably attached to the one or more end covers 122, move along the one or more end covers 120 closer in proximity to the leading edge 106. When the roll of paper products 200 is at maximum capacity, the attachment mechanisms 124 are releasably attached to one or more end covers 120 proximate to the distal end 108.

FIG. 2D is an expended view of an embodiment of the apparatus 111, in accordance with one embodiment of the present invention. As illustrated in FIG. 2D the flexible sheet 102 comprises a leading end 106 and a first side edge 110. The semi-flexible sheet 102 further comprises end cover 120 with angled spaces 122 between each end cover 120. Referring the FIG. 2D, the semi-flexible sheet 102 may have multiple attachment mechanisms 124, where each attachment mechanism is attached to at least one of the end covers 120.

FIG. 2E illustrates an expended view of the attachment mechanism of the apparatus 115, in accordance with one embodiment of the present invention. The attachment mechanism 124 is attached and perpendicular to the end covers 120. While only one attachment mechanism 124 is illustrated in FIG. 2E, one of ordinary skill in the art will appreciate that multiple attachment mechanisms 124 may be present. The attachment mechanism 124 is attached to the end cover 120 on the leading edge 106 of the semi-flexible sheet 102. The expanded view illustrated in FIG. 2E illustrates the attachment mechanism 124 on the first side edge 110 of the semi-flexible sheet 102. As illustrated in FIG. 2E, the attachment mechanism 124 forms a J shape clip. The attachment mechanism 124 comprises a top surface 126 that connects to and is located perpendicular to the end cover 120 and a front surface 128 which is connected to and perpendicular to the first edge 126 of the attachment mechanism 124.

In some embodiments, the attachment mechanism 124 may be a clip that is connected to the first side edge 110 of the semi-flexible sheet 102 such that a portion of the clip is designed to apply pressure to a portion of the semi-flexible sheet 102 against another portion of the semi-flexible sheet 102. In various embodiments, the clip may be made of the same material of the semi-flexible sheet 102 and be formed from the first side edge 110 of the semi-flexible sheet 102.

The clip may include a top surface 126 and a front surface 128. The top surface may connect with the first side edge 110 (as illustrated in FIG. 2A-2B) or the end cover 120 (FIG. 2C-2E) of the semi-flexible sheet 102. The top surface 126 may be located in a face-to-face relation with the semi-flexible sheet 102 such that a gap is formed between the front surface and the semi-flexible sheet 102. In some embodiments, the gap is sized depending on the thickness of the semi-flexible sheet 102 and the paper product held therein. In other embodiments, the gap is smaller than the thickness of the semi-flexible sheet 102. The attachment mechanism 124 functions as a J shaped clip that is operated by placing a portion of the semi-flexible sheet 102 between attachment mechanism 124 and the semi-flexible sheet 102 when the semi-flexible sheet 102 is radially collapsed. Thus the clip retains the semi-flexible sheet 102 in a cylindrical shape of a given dimension. The portion of the semi-flexible sheet 102 positioned in the gap of the clip may be operatively removed at any time, thus allowing a user to insert a roll of paper product into the apparatus.

In this way, after inserting the roll of paper product, the user may place the semi-flexible sheet 102 in to the clip and thus retain the semi-flexible sheet 102 in the collapsed radial position tight around the roll of paper product. Furthermore, the gap created between the two portions of the semi-flexible sheet between the attachment mechanism allows a single sheet of the paper product to be dispensed through the gap. As the paper product is dispensed and the outer diameter of the roll of paper product is reduced, the clip may be positioned such that an inner diameter of the semi-flexible sheet 102 is equal to the outer diameter of the roll of paper product.

In other embodiments, the attachment mechanism may include multiple attachment regions in order to operate. Examples of such a mechanism might include, but is not limited to, zippers, magnets, adhesive, buttons, clasps, snaps, straps, hock, eyelets, Velcro®, and the like. Where the attachment mechanism requires multiple attachment regions, the attachment mechanism may comprise a first attachment region that attaches to at least a second attachment region. The first attachment region may be located along an edge or end of the semi-flexible sheet. The location of the second attachment mechanism may be located at one or more positions along the first or second edge of the semi-flexible sheet. For example, where the attachment mechanism is a snap, the snap may consist of at least an insertion piece located at a corner next to the leading end, multiple receiving pieces. The insertion piece may be located where the leading end 106 and the first side edge 110 form a corner. The multiple receiving pieces may be located along the first side edge 110 such that the insertion piece may be connected with any one of the multiple receiving pieces. By connecting the insertion piece with a given receiving piece, the diameter of the cylindrical shape may be adjusted. While attachment mechanisms are generally described above as being on the first side edge 110, one of ordinary sill in the art will appreciate that the attachment mechanisms may also be the same or similar along the second side edge 112.

FIG. 2F illustrates the attachment mechanism 124 attaching to a multiple portions of the semi-flexible sheet 102B. As the roll of sheet material 200 is dispensed, the semi-flexible sheet 102 radially contracts. As the radius of the semi-flexible sheet 102 is reduced, the leading end 106 travels tangential to the curvature of the semi-flexible sheet 102. When enough of the sheet material 200 has been dispensed, the leading end 106 travels passed the distal end 108 for a second time and the attachment mechanism 124 is configured to hold multiple portions of the either the first side end 110 or the second side end 112.

As illustrated in FIG. 3, the taper may begin at any point located near or at the leading end 106 and travels along the first side edge 110 and the second side edge 112, thus forming a consistent taper along the first side edge 110 and the second side edge 112. The taper may be symmetric to a center line of the semi-flexible sheet 102 formed by the leading edge 106 and the distal edge 108. In other embodiments, the taper is located on either the first side edge 110 or the second side edge 112 but not both. In some embodiments, the taper may be small and make the leading end 106 only slightly longer than the distal end 108. In some embodiments, the taper may be larger and make the leading end 106 significantly longer than the distal end 108. The taper is then designed to fit into the paper product, this allowing for easy alignment of the apparatus onto and over the roll of paper product. Furthermore, this taper allows a sheet of the paper product to be dispensed through the gap created by the apparatus, such that a single sheet may be dispensed at a time.

In some embodiments, a length between the first side edge and the second side edge is greater than the circumference of a full roll of paper product. Therefore, the length between the first side edge 110 and the second side edge 112 is sufficient that a portion of the semi-flexible sheet 102 entirely covers the roll of paper product.
