This present application claims priority from U.S. Provisional Application No. 61/243,695 filed Sep. 18, 2009, which is titled “Paper-Towel Apparatus for Reusing Non-Structured Paperless Paper-Towels and from U.S. Provisional Application No. 61/243,705 filed Sep. 18, 2009, which is titled “Paper-Towel Apparatus for Reusing Non-Structured Paperless Paper-Towels,” the entire contents of each of which are incorporated by reference.
TECHNICAL FIELDThis document relates to an apparatus configured to enable reuse of paperless paper-towels.
BACKGROUNDDisposable paper-towels are commonly found in households and commercial businesses. For example, a long flat paper sheet is stamped into numerous loosely connected tissue paper sections (or tissues) and wrapped around the circumference of a cardboard tube to form a traditional paper-towel roll. The tissues of a traditional paper-towel roll are structured in that they are organized as a circumferential wrapping which spirals around the cardboard tube. Each tissue can be unwrapped and detached from the next tissue by a slight physical force.
Also, tissue paper sections can be separated and structured in an enclosed container with a thin opening during manufacturing so as to enable removal of tissues one at a time. In particular, the tissues can be stacked in a box, one directly on top of another, such that removal of the final tissue pulls the next tissue to expose a flap of the tissue for ease of handling through the thin opening. In this configuration, the tissues are not connected after manufacture.
SUMMARYIn general, in some aspects, a reusable towel dispenser includes a reusable towel holding compartment and a reusable towel output of the reusable towel holding compartment, the reusable towel output being configured to enable a reusable towel to be removed from the reusable towel holding compartment. The dispenser also includes a reusable towel input of the towel holding compartment, the reusable towel input being configured to allow reusable towels to be loaded in the reusable towel holding compartment. The dispenser further includes a mounting structure configured to mount the reusable towel dispenser to a paper-towel holding-rod of a paper-towel holder using a clamp. The clamp includes a crevice configured to hold the paper-towel holding-rod. Also, the clamp includes opposing pieces that are configured to be pushed toward each other such that the opposing pieces substantially surround the paper-towel holding-rod.
In other implementations, some aspects include a reusable towel dispenser which includes a reusable towel holding compartment and a reusable towel output of the reusable towel holding compartment, the reusable towel output being configured to enable a reusable towel to be removed from the reusable towel holding compartment. The dispenser additionally includes a reusable towel input of the towel holding compartment, the reusable towel input being configured to allow reusable towels to be loaded in the reusable towel holding compartment. Furthermore, the dispenser includes a mounting structure configured to mount the reusable towel dispenser to a paper-towel holder.
This and other implementations can optionally include one or more of the following features, which also may optionally be in any combination. For example, the mounting structure can include a fastener configured to fasten the reusable towel dispenser to a paper-towel holding-rod. The dispenser can include an operating mechanism of the fastener. To fasten the reusable towel dispenser to the paper-towel holding-rod, the fastener can be configured to apply pressure around the paper-towel holding-rod as an operating mechanism is rotated. The operating mechanism can be a cap.
Also, the mounting structure can include a clasp configured to clasp the reusable towel dispenser to a paper-towel holding-rod of the a paper-towel holder. The clasp can include two opposing curved arms and a spring configured to push the opposing arms towards each other. To clasp the reusable towel dispenser to the paper-towel holding-rod, the opposing curved arms can be configured to be able to be moved outward such that the paper-towel holding-rod can pass between the opposing curved arms. The clasp can include a metal spring configured to form a loop. To clasp the reusable towel dispenser to the paper-towel holding-rod, the spring can be configured to be able to be opened such that the loop becomes large enough to allow passage of the paper-towel holding-rod.
Further, the mounting structure can be configured to mount the reusable towel dispenser to an ear-muff style paper-towel holder. The mounting structure can include a cable configured to wrap around one or more ends of the ear-muff style paper-towel holder. The dispenser can include a spring-loaded rod configured to retract slack from the cable into the reusable towel dispenser. The mounting structure can include a grip configured to be placed around ends of the ear-muff style paper-towel holder. The grip can be configured to press the ends of the ear-muff style paper-towel holder inward towards the reusable towel dispenser. In addition, the dispenser can include a locking mechanism configured to lock the mounting structure in a position where the reusable towel dispenser is mounted to the paper-towel holder.
Moreover, the dispenser can include a hollow cylindrical center of the reusable towel dispenser configured to allow passage of a paper-towel holding-rod of the a paper-towel holder. An inner surface of the hollow cylindrical center can be covered with an elastomer. The mounting structure can include a clamp configured to clamp the reusable towel dispenser to a paper-towel holding-rod. The clamp can include a crevice configured to hold the paper-towel holding-rod. The clamp can include opposing pieces that are configured to be pushed toward each other such that the opposing pieces substantially surround the paper-towel holding-rod.

DETAILED DESCRIPTIONTraditional paper-towels are paper-based tissues which are briefly used and then discarded. Therefore, all of the energy and resources used to manufacture, transport, sell, and dispose of each tissue goes towards a single use. In the aggregate, the environmental impact of a society reliant on disposable paper-towels is massive. Reusable paper-towels, however, can be manufactured out of various materials which can be washed without being destroyed. A paper-towel system allowing for the reuse of paper-towels could cut this environmental impact to a small fraction of its current state.
Paper-towels wrapped around a paper-towel roll are structured as a loosely connected number of sections which are tightly spiraled around a cylindrical center. This spiral structuring is put in place during manufacturing. Because the paper-towel roll requires each separate tissue to be connected in series, a consumer could not reuse the paper-towel roll as a dispenser for reusable paper-towels. Therefore, once the paper-towels are used, the paper-towels and the paper-towel roll are not reusable by the consumer and are all discarded.
Products like Kleenex™ tissues are sold in a container with the tissues disconnected and stacked on top of each other. The structure of the stacked tissues enables the tissues to be removed from a small opening without being replaced. The small opening is wide enough to allow passage of a tissue vertically with respect to the small opening, though not its length. Tissues can only be removed if directly pulled. As structured, each tissue is placed flat atop the preceding tissue and a portion of each tissue is folded into the proceeding tissue. As the tissue closest to the opening is removed, the next available tissue is pulled to expose an end which can also be easily removed through the small opening.
This structuring of Kleenex™ tissues is directed to a one-time use of disposable tissues. The small opening enables tissues to be removed but does not enable a consumer to replace a tissue once removed. Moreover, even if a consumer could somehow replace the tissue, the consumer would be forced to replicate the stacked and folded structure to be able to again easily remove the tissues through the small opening. It is not practical to expect consumers to fold small tissues in this manner. Therefore, these containers are not suitable for a reusable paper-towel system using conventional tissues.
In order to enable a consumer to easily use and reuse a reusable a paper-towel, a paper-towel container can be used which allows reusable paper-towels to be refilled without a particular structuring of the paper-towels. That is, a consumer can place an unorganized mass of cleaned paper-towels in the container even if the reusable paper-towels are not attached to each other in a spiral formation and are not placed flat on top of each other or interlaced. By not requiring a structuring of refilled paper-towels, the paper-towel container aids consumer adoption of reusable paper-towels.
Various materials can be used to construct the reusable paper-towels. For example, non-woven cotton can be manufactured relatively cheaply with various properties advantageous for use as a reusable paper-towel. In particular, non-woven cotton can be made to dry relatively quickly to prevent or limit development of mold after use. Also, non-woven cotton can be manufactured to be relatively coarse for scrubbing or relatively soft for comfort. Microfiber can also be used. Microfiber can be useful to avoid staining and for longevity. Reusable paper-towels can be color coded based on properties, such as materials, size, or shape. However, the size of the reusable paper-towel can be used to control the ease with which the reusable paper-towels are unloaded. For example, a towel size that is too large can promote a group of towels to wrap together such that a single towel is not easily separated. Moreover, a towel size that is too large can inhibit the ease with which a towel is removed from an opening of a reusable paper-towel apparatus. In contrast, a towel size that is too small can increase the likelihood that towels fall out or are otherwise accidentally removed from an opening of a reusable paper-towel apparatus. Therefore, a consumer can you use color identification to select one or multiple non-structured reusable paper-towels from a paper-towel container for a given situation.
One example of such a paper-towel container is the reusable paper-towel holding apparatus 100 with a protruding portion shown in
The inner circumferential casing 111 can be configured to allow passage of a paper-towel roll holding-rod (not shown). In particular, the inner circumferential casing 111 can define an inner hollow space 114 which is open at either end. By being open at either end, a paper-towel roll holding-rod can pass through the inner hollow space 114 such that the apparatus 100 can be mounted on a paper-towel roll holder. The outer circumferential casing 112 largely surrounds the inner circumferential casing to define the paper-towel holding compartment 113.
The apparatus 100 enables reusable paper-towels to be reloaded with a front loading mechanism. In particular, the outer circumferential casing 112 is able to move with respect to the inner circumferential casing 111 to provide a large input opening 115 with which reusable paper-towels can be loaded into the paper-towel holding compartment 113. By using a front loading mechanism, the apparatus 100 may be easily reloaded without being removed from a mounting with a paper-towel holding-rod. To enable convenient loading when non-structured, the input opening 115 created by the front loading mechanism must be of a substantial size relative to the side-length of the reusable paper-towel. By being a substantial size, a group of reusable paper-towels can be conveniently loaded at the same time, even when clumped or otherwise disorganized. In some implementations, to enable ease of loading, the span of the input opening 115 created by the front loading mechanism should be large enough so that at least three clumped reusable paper-towels can be loaded. Particularly flexible or thin reusable paper-towels may be loaded with less span of the input opening 115 while particularly inflexible or thick reusable paper-towels may load easily only with more span of the input opening 115.
The outer circumferential casing 112 includes a protruding portion 116 which defines an output opening 117 to the reusable paper-towel holding compartment 113 which allows access to reusable paper-towels stored in the reusable paper-towel holding compartment 113. The output opening 117 serves as the primary mechanism from which reusable paper-towels are removed from the apparatus 100 for each use. Since the reusable paper-towels are pulled out of the apparatus 100 rather then being pushed in, the size required of the opening 117 is smaller than that required for the input opening 115 created by the front loading mechanism to load the apparatus 100. However, because the reusable paper-towels in the reusable paper-towel holding compartment 113 are not structured, the user may need to reach partially inside the apparatus 100 to grab on to a portion of a reusable paper-towel and remove it from the apparatus 100. Therefore, the output opening 117 can be made wide enough to allow a portion of a thumb and finger to pass, such as a span of one to two inches. The output opening 117, however, is generally not made significantly larger than required to prevent reusable paper-towels from unintentionally falling or sliding out of the apparatus 100.
The output opening 117 is located on the bottom of the apparatus 100, as mounted. This location allows gravity to progressively move reusable papers towards the output opening 117 as the reusable paper-towels are withdrawn. In particular, when filled, reusable paper-towels fill much of the volume of the reusable paper-towel compartment 113. As reusable paper-towels are removed from the apparatus 100, an empty space is made at the bottom of the apparatus 100. Due to gravity, the reusable paper-towels fall toward the bottom of the apparatus 100, filling the empty space and placing additional reusable paper-towels close to the output opening 117 for ease of removal. As shown, the output opening 117 is located at the bottom of the apparatus 100 but does not open to expose the underside of the apparatus 100. Also, the output opening 117 is not oriented vertically as mounted. Rather, the output opening is positioned at approximately a 45 degree angle above a horizontal planar direction. This non-vertical and non-horizontal positioning of the output opening 117 further minimizes the unintentional removal of reusable paper-towels. Also, this non-horizontal position of the output opening 117 enables a somewhat larger width of the output opening 117 while minimizing unintentional removal than would be enabled if the output opening 117 exposed the underside of the apparatus 100.
The above description of the apparatus 100 as well as the below description of additional features are examples. Other implementations may be configured differently and with different features. For example, other implementations of the apparatus 100 may include a substantially cone shape with the output opening 117 at the bottom of the apparatus 100 to emphasize the use of gravity in bringing towels closer to the output opening 117.
The apparatus 200 is configured to be mounted using ear-muff holders 229 without necessarily passing a paper-towel holding-rod 228 through the apparatus 200. In particular, the outer circumferential casing 222 defines mounting openings 224 which can be used to allow passage of a paper-towel holding-rod 228 (similar to the inner circumferential casing 111 of
The outer circumferential casing 222 defines an output opening 227 to the reusable paper-towel holding compartment which allows access to reusable paper-towels stored in the reusable paper-towel holding compartment, but does not include a protruding portion 116. Similar to
In some implementations, the mounted apparatus 300B is able to be rotated, similar to a conventional paper-towel role. Therefore, including only a single output opening would require the user to rotate the apparatus 300B such that the single output opening is in front of the user in order to extract a reusable paper-towel. However, the multiple output-openings 332B-338B shown in
Also, regardless of whether the apparatus 300B can be rotated, the multiple output openings 332B-338B can allow for the user to extract reusable paper-towel from multiple directions, as mounted. Therefore, in any given situation, extraction of a reusable paper-towel is more likely to be convenient to a user than extraction with an apparatus with only a single output opening. This feature can be particularly useful for reusable paper-towel mounts which do not allow for rotation of a reusable paper-towel holding apparatus after mounting. The apparatus 300B can also be mounted with a paper-towel holding rod, ear-muffs, or other mounting styles discussed above and below.
As discussed above, a reusable paper-towel holding apparatus may not be shaped identically to a conventional paper-towel roll. Nevertheless, it may be convenient for a user to mount the reusable paper-towel holding apparatus on a conventional paper-towel holding-rod.
The mounting mechanisms of
The flexible circumference 510 may be formed with such dimensions that the paper-towel holding-rod presses against the flexible circumference 510 when slid through the hollow cylinder 520. In general, the diameter of the hollow cylinder 520 may be slightly larger to slightly smaller than the diameter of a paper-towel holding-rod. A diameter of the hollow cylinder 520 which is about the same size or slightly smaller than the diameter of a paper-towel holding-rod can be used to create a pressure from the flexible circumference 510 on the paper-towel holding-rod. The pressure on the paper-towel holding-rod can create friction which keeps the reusable paper-towel holding apparatus 500 in place on a paper-towel holding-rod. Moreover, the surface of the flexible circumference 510 may be uneven or ruff to augment the amount of friction.
When a paper-towel holding-rod is pushed into the protruding portion 614A, the semi-flexible shape responds by opening slightly, enabling the rod to be mounted securely inside the crevice 613A. A further force is required to pull the paper-towel holding-rod out of the mounting in the crevice 613A. The holding-rod clamp 612A can be placed at the ends of the reusable paper-towel holding apparatus 610A. In one implementation, the holding-rod clamp 612A is configured to be mounted on the paper-towel holding-rod by being pushed inward towards the center of the device. Once pushed inward, the holding-rod clamp 612A is even with the surface 616A of the reusable paper-towel holding apparatus 610A such that the holding-rod clamp 612A exhibits no profile.
The teeth 624B can then be used to lock the end-pieces 626B in the pressed inward position such that they are pressed around the paper-towel-holding-rod. When locked by the teeth 624B, the end-pieces 626B can apply a pressure to the paper-towel holding-rod. In this manner, a reusable paper-towel holding apparatus 620B can be mounted on a paper-towel holding-rod. The locking by the teeth 624B can later be reversed through a further user manipulation of, for example, a cap or lever. In some implementations, the end-pieces 626B are made out of a flexible material and flex partly around the paper-towel holding-rod when forced.
User manipulation by, for example, the twisting of a cap or pressing of a button or lever is used to create a pressure on the arm pieces 714A. This pressure on the arm pieces 714A presses the adjacent round pieces 716A inward. As the round pieces 716A are pressed inward, the round pieces 716A are pushed against a paper-towel holding-rod which has been slid through the hollow center of the reusable paper-towel holding apparatus 710A. The pressure between the round pieces 716A and the paper-towel holding-rod is used to mount the reusable paper-towel holding apparatus 710A on the paper-towel holding-rod.
The spring 815A is configured to continuously apply pressure forcing the opposing arms 813A and 814A together. In some implementations, the opposing arms 813A and 814A are metal so as to ensure strength. In other implementations, the opposing arms 813A and 814A are rubber or plastic, so as to maintain flexibility.
To operate the holding-rod clasp 812A, the opposing arms 813A and 814A are pulled apart to create an opening in which the paper-towel holding-rod can slide through. The opposing arms 813A and 814A can be pulled apart through, for example, turning of a cap, pressing of a leveler, direct user manipulation, or through other means. Once the paper-towel holding-rod is slid through, the opposing arms 813A and 814A are released. Thereafter, the pressure created by the spring 815A forces the opposing arms 813A and 814A to wrap around and place pressure on the paper-towel holding-rod. This pressure is used to mount the reusable paper-towel holding apparatus 810A on the paper-towel holding-rod.
In one implementation, the holding-rod clasp 822B is formed with a metal spring that includes a rubber grip. The metal spring is formed to continuously apply pressure to shrink the loop. To insert the paper-towel holding-rod through the loop, the user must first operate a cap or lever to force open the spring, increasing the size of the loop. Thereafter, the user releases the cap or lever and the metal spring returns to its original shape, squeezing the paper-towel holding-rod.
In another implementation, the holding-rod clasp 822B is formed with a rubber line. As mounted on the reusable paper-towel holding-rod apparatus, the rubber line maintains a loop larger than a paper-towel holding-rod, enabling a user to simply insert the paper-towel holding-rod through the loop. Thereafter, the user must operate a cap or lever connected to locking teeth to tighten the loop. The tightened loop squeezes the paper-towel holding-rod.

The reusable paper-towel holding apparatus 940D of
In various implementations, the reusable paper-towel holding apparatus can use flexible end-caps along with, or in lieu of, the features described with respect to
Depending upon the circumstance, a reusable paper-towel may be used multiple times before being cleaned. For instance, while a reusable paper-towel used to wipe food parts may not remain sanitary after a single use, a reusable paper-towel used to dry a washed dish may remain sanitary after multiple uses. For various reasons, however it may not be practical for the user to simply reinsert a used but sanitary reusable paper-towel into a reusable paper-towel holding apparatus.
As discussed above, many implementations of reusable paper-towel holding apparatus are configured to maintain non-structured paper-towels which can be removed through an opening which is configured to allow ease of removal but not ease of insertion. As such, to easily reinsert a used reusable paper-towel, a user may be required to open a separate loading mechanism and/or dismount the reusable paper-towel holding apparatus. Such a requirement may not facilitate using a reusable paper-towel multiple times before washing.
Moreover, after a use, a reusable paper-towel may be wet. Reinserting a wet reusable paper-towel into an enclosed compartment may facilitate the growth of mold or otherwise lead to non-sanitary conditions. Therefore, a user may wish to dry the towel before placing the towel in the reusable paper-towel holding apparatus of reusing.
Accordingly, in order to enable a user to use a reusable paper-towel multiple times before cleaning, external reusable paper-towel holding structures may be used.
The reusable paper-towel holding apparatus 1020B of
In some implementations, the reusable paper-towel holding apparatus is configured to hold both used (i.e., soiled) and unused (i.e., cleaned) reusable paper-towels internally. Such implementations can be convenient in that they can allow for reusable paper-towels to be kept together, both before and after they are used. Moreover, such implementations can be particularly useful for portable reusable paper-towel apparatus.
