The present invention provides a method and system for efficiently storing and dispensing rolled paper products.
For many years, since the advent of the use of disposable paper products, consumers have been faced with the problem storing the often bulky products. With the rise of warehouse-style shopping, many consumers purchase paper products in bulk in order to save money and reduce the frequency of shopping trips. Bulk packaging of paper products may include as many as twelve or more individually-packaged rolls of the paper product. Unfortunately, bulk packaging of paper products results in packages that are too large to store conveniently in many homes and businesses. The volume of space taken up by the many rolls of paper products makes a bulk purchase space-prohibitive despite a savings in price and time. As a result, consumers forgo reduced prices and distributors and bulk retailers lose business. Accordingly, consumers, distributors and bulk retailers have recognized a need for an inexpensive system and method for convenient storage and dispensing of paper products.
One embodiment of the present invention comprises an enclosed rectangular collapsible container (“dispenser”) for storing and dispensing one or more rolls of paper towels. The dispenser has dimensions appropriate for holding up to twelve horizontally-placed rolls of paper towels in two vertical stacks of up to six rolls each. The width of the dispenser is at least equal to the height of a standard roll of paper towels, the height of the dispenser is approximately six times the diameter of a standard roll of paper towels, and the depth of the dispenser is approximately two times the diameter of a standard roll of paper towels. A dispensing aperture is included proximal to the bottom of the front piece of the dispenser for manual extraction of the enclosed paper-towel rolls. The dispensing aperture has dimensions corresponding to the approximate height and approximate diameter of a horizontally-placed roll of paper towels. The dispensing aperture further contains a projection cut out along the top edge large enough for a user to manually reach into the dispenser and extract a roll of paper towels. Removal of a paper towel roll from the dispensing aperture causes any paper towel rolls directly above the extracted paper towel roll to shift downward to the bottom of the dispenser, positioning a new roll of paper towels directly inside of the dispensing aperture for later removal from the dispenser.
Various alternate embodiments of the dispenser include a viewing aperture, placed on the front piece of the dispenser, for viewing the contents of the dispenser and a shaped bracket that extends upward from the back piece and that is flush with the dispenser for mounting of the dispenser to the top edge of a door. In various embodiments, the top and bottom pieces of the dispenser can both be opened for convenient loading of the dispenser with paper towel rolls from either end. When both the top and bottom pieces are simultaneously opened in various embodiments, the dispenser may be folded flat for efficient storage when the dispenser is not is use.
One embodiment of the present invention comprises a hanging, collapsible paper towel roll dispenser.
The front piece 108 of the paper towel roll dispenser 102 includes a dispensing aperture 116 for extracting paper towel rolls from the dispenser 102. The dispensing aperture 116 includes an extraction space 118 for manually reaching into the dispenser 102 to pull out a paper towel roll through the dispensing aperture 116. The front piece 108 of the dispenser 102 further includes a viewing aperture 120 providing an opening for visually inspecting the contents of the dispenser 102. A mounting bracket 122 is attached to the back piece 106 of the dispenser 102. The mounting bracket 122 extends upward, flush with the back piece 110 of the dispenser 102 and provides a means for mounting the dispenser 102 to a door.
In an alternative embodiment of the dispenser, not shown, the top piece is horizontal, as shown in
Two top stiffening flaps 208 and 210 are pivotably attached to the dispenser 102 along the top edges of two opposing vertical pieces, such as the front piece 108 and the back piece 110. The top stiffening flaps 208 and 210 have lengths of slightly less than the width of the vertical pieces to which the stiffening flaps 208 and 210 are attached, the front piece 108 and the back piece 110 respectively. The difference between the widths of vertical pieces 108 and 110 and the attached top stiffening flaps 208 and 210 create an open strip 212 perpendicularly abutting side piece 114. The width of the open strip 212 is approximately equal to the thickness of top flap 202.
Two top pivoting tabs 214 and 216 extend from the proximity of the top edge of the vertical piece opposite to the vertical piece attached to the top piece 104.
Closing the top piece may be done in several orderly steps. First, the pivoting tabs 214 and 216 are pivoted outward from attached side piece 114, along the base pivot 218 and 220. Next, the top stiffening flaps 208 and 210 are folded inward as indicated by directional arrows 234 and 236. Each top stiffening flap 208 and 210 contains a tab avoidance aperture 238 and 240 respectively along the edge of the top stiffening flap 208 and 210 adjacent to the pivot tabs 214 and 216 when the stiffening flaps 208 and 210 are folded inward. The tab avoidance apertures 238 and 240 are of width at least equal to the width of the pivoting tabs 214 and 216 and are positioned such that, when the top stiffening flaps 208 and 210 are folded horizontally, the tab avoidance apertures 238 and 240 align with the pivoting tabs 214 and 216 respectively.
In a next step, the top piece 104 is folded inward as indicated by directional arrow 242. As the top piece 104 is brought to a horizontal position, the top flap 202 may be tucked inside of side piece 114 along open strip 212. Insertion slits 204 and 206 align with pivoting tabs 214 and 216 respectively when the top piece 104 is properly closed in a horizontal position. Once the top piece 104 is closed, the top piece 104 may be secured by manually pressing the leading edges 226 and 228 of the pivoting tabs 214 and 216 through the insertion slits 204 and 206 until the bottom half of the pivoting tabs 214 and 216 are flush with the side piece 114. Note that, when the top piece 104 is securely fastened, the pivoting tabs 214 and 216 are at approximately right angles, bending along the middle pivot 222 and 224. Also note that, when the top piece 104 is securely fastened, the top half of the pivoting tabs 214 and 216 are in a horizontal plane with the top stiffening flaps 208 and 210, inside of the tab avoidance apertures 238 and 240, providing a rigid plane underneath the top piece 104 to help maintain the rectangular shape of the dispenser 102.
Opening the top piece of the dispenser may be performed by reversing the above orderly steps for closing the top piece, beginning with manually reaching into the grabbing apertures 230 and 232 flanking the pivoting tabs 214 and 216 and applying an outward force to separate the leading edges 226 and 228 of the pivoting tabs 214 and 216 from the insertion slits 204 and 206, lifting up the top piece 104 in a motion opposite to directional arrow 242, then lifting the top stiffening flaps 208 and 210 in directions opposite to directional arrows 234 and 236.
In the embodiment shown in
The second embodiment, illustrated in
An inner section 308 extends from the inner terminus 304 inside the dispenser 102, through a mounting slit 310 in the back piece 110 of the dispenser 102, to a resting edge 312 flush with the exterior of the back piece 110. From the resting edge 312, the bracket 302 bends upward along a first vertical section 314 running approximately parallel to, and flush with, the back piece 110 of the dispenser 102. Note that the angle 316 between the inner section 308 and the first vertical section 314 is not greater than ninety degrees to prevent the dispenser 102 from losing contact with the resting edge 312 when the dispenser 102 is in an upright position. The first vertical section 314 extends upward beyond the plane of the horizontal top piece 104 of the dispenser 102. The bracket 302 bends approximately ninety degrees away from the dispenser 102 extending along a horizontal section 316 of the bracket 302 before bending approximately ninety degrees for a second time, extending down a second vertical section 318 in a direction parallel and opposite to the first vertical section 314, to the outer terminus 306.
The first vertical section 314 and the second vertical section 318 are spaced apart to fit snugly along the two main faces of a standard two-inch-thick door (about one and three-fourths inches). When the dispenser 102 is properly mounted to a door, as shown in
A stiffening flap 408 is pivotably attached to the dispenser 102 along the bottom edge of one of the vertical pieces, such as back piece 110, adjacent to the vertical piece pivotably attaching the bottom piece 106. The bottom stiffening flap 408 has a length of slightly less than the width of the vertical piece to which the stiffening flap 408 is attached, shown in
Two bottom pivoting tabs 412 and 414 extend from the proximity of the bottom edge of the vertical piece opposite to the vertical piece attached to the bottom piece 106.
Closing the bottom piece may be done in several orderly steps. First, the pivoting tabs 412 and 414 are pivoted outward from attached side piece 114, along the base pivot 416 and 418. Next, the bottom stiffening flap 408 is folded inward as indicated by directional arrow 432. The bottom stiffening flap 408 contains two tab avoidance apertures 434 and 436 along the edge of the stiffening flap 408 adjacent to the pivot tabs 412 and 414 when the stiffening flap 408 is folded inward. The tab avoidance apertures 434 and 436 are of width at least equal to the width of the pivoting tabs 412 and 414 and are positioned such that, when the bottom stiffening flap 408 is folded horizontally, the tab avoidance apertures 434 and 436 align with the pivoting tabs 412 and 414 respectively.
In the next step, the bottom piece 106 is folded inward as indicated by directional arrow 438. As the bottom piece 106 is brought to a horizontal position, the bottom flap 402 may be tucked inside of side piece 114 along open strip 410. Insertion slits 404 and 406 align with pivoting tabs 412 and 414 respectively when the bottom piece 106 is properly closed in a horizontal position. Once the bottom piece 106 is closed, the bottom piece 106 may be secured by manually pressing the leading edges 424 and 426 of the pivoting tabs 412 and 416 through the insertion slits 404 and 406 until the bottom half of the pivoting tabs 412 and 414 are flush with the side piece 114. Note that, when the bottom piece 106 is securely fastened, the pivoting tabs 412 and 414 are at approximately right angles, bending along the middle pivot 420 and 422. Also note that, when the bottom piece 106 is securely fastened, the bottom half of the pivoting tabs 412 and 414 are in a horizontal plane with the bottom stiffening flap 408, inside of the tab avoidance apertures 434 and 436, providing a rigid plane underneath the bottom piece 106 to help maintain the rectangular shape of the dispenser 102.
Opening the bottom piece of the dispenser may be performed by reversing the above orderly steps for closing the bottom piece, beginning with manually reaching into the grabbing apertures 228 and 430 flanking the pivoting tabs 412 and 414 and applying an outward force to separate the leading edges 424 and 426 of the pivoting tabs 412 and 414 from the insertion slits 404 and 406, lifting up the bottom piece 106 in a motion opposite to directional arrow 432, and then lifting the bottom stiffening flap 408 in a direction opposite to directional arrow 438.
The second embodiment, illustrated in
Alternate embodiments of the dispenser 102 may be fabricated from any number of materials, both pliable and non-pliable, including corrugated cardboard or other heavy paper material, plastic, Coroplast™, metal, wood, sturdy fabric, and laminate material. If a pliable material, such as cardboard, is used, then simultaneously opening up the top piece and bottom piece of the dispenser 102 allows the dispenser 102 to fold flat for convenient storage of the dispenser 102 when not in use.
