This invention relates generally to dispensing a web material; and more particularly to a method and apparatus for dispensing toilet paper in a sanitary, ergonomic and convenient fashion; and more particularly still to a toilet paper roll dispenser that includes U.V. germicidal light, a heat source to warm the toilet paper and a courtesy light.
There are many types and styles of toilet paper dispensers. For example, there are single spindle arm holders, spring loaded and pivoting spindle arm holders, locking holders, recessed holders and commercial holders for single and double rolls, among others. In general, each type of holder includes a spindle which extends through the roll of toilet paper such that the toilet paper is rotatably positioned on the spindle.
The toilet paper itself generally is manufactured using paper in sheets or on a roll for wiping oneself clean after urination or defecation. More specifically, it is generally a tissue paper product typically used to clean the anus and surrounding area of feces after defecation and/or to clean the perineal area of urine after urination or other bodily fluid. In addition to cleaning and absorbing feces and urine, the toilet paper acts as a layer of protection for the hands during these processes. Usually, it is supplied as a long strip of tissue paper wrapped around a paperboard core in a dispenser near a toilet. The resulting roll of web materials may be referred to by a variety of names including toilet paper, toilet tissue, wipes, toilet roll and/or loo roll (referred to collectively herein as “toilet paper” or “toilet tissue”).
One toilet paper holder is described in U.S. Pat. No. 5,697,577. In that patent the toilet paper is premoistened and the toilet paper is located in a chamber that is substantially sealed to prevent evaporation of the moisture on the toilet paper roll. A door is provided to selectively provide access to the chamber and to the moistened toilet paper. Heating the moistened toilet paper is accomplished through wires attached to the inside of the housing or a light bulb located below the toilet paper. A button is located on the front of the housing to initiate heating. In either case, however, due to the methods of heating, there is a significant drain of power and time associated with warming the outer-most layer of toilet paper.
Another toilet paper holder is described in U.S. Pat. No. 6,476,365. In this holder, toilet paper with an anti-bacterial lotion is heated by using a heating element positioned in the bottom portion of the housing. The housing pivots to an open position to provide access to the toilet paper. The heating element is not described.
Therefore, there is a need in the art for a method and apparatus for providing a toilet paper dispenser with improved sanitary, ergonomic and convenience features. The present invention addresses these and other needs in the art.
A preferred embodiment of a method and apparatus constructed in accordance with the principles of the present invention is a device that provides additional comfort and a more sanitary environment when using toilet paper. More specifically, the device includes various features and options to warm the toilet paper and irradiate the toilet paper with germicidal UV light. Further, an additional light may be provided for the convenience of the user at night or other low light applications. Each of the foregoing may be initiated by the user, initiated by a motion or touch sensor, and/or initiated by a timer. To further increase flexibility, the device may be powered by a battery pack or may be plugged into a wall outlet.
The device includes optional housings to locate the toilet paper within the housing, on a face of the housing, adjacent to or above an existing toilet paper holder. Thus, the device may be installed as an initial fixture within a bathroom (e.g., a bathroom being constructed or remodeled) or as a retrofit addition for those bathrooms already having fixtures.
One advantage of the device is that the device uses a heating methodology for the toilet paper that quickly warms the several outermost layers. It does this by using a heater element with a fan blowing across the heater element. Using this type of convection heat in close proximity to the toilet paper warms the outermost layers of the toilet paper rapidly. Another type of heating that may be used is a polyimide heater film. Such films provide fast preheating speed, are durable, lightweight and may include an adhesive to provide specific desired placement of the heating element.
Another advantage of the device is that use of a germicidal UV light reduces the risk of transmission of germs between users of the toilet paper and toilet paper dispenser.
Still another advantage of the device is that the device can include electronic controls, thereby building in a variety of optional control functions. The control functions can be preprogrammed or can be provided as options for individual users. An optional feature of the device is use of an app (or application program), which may be operated on a smart device to control the toilet paper dispenser functions. More specifically, various functions may be performed and user preferences established—such as whether to use each function, how long and when to turn on the UV lights, how long and when to turn on the heater (as well as the preferred temperature), how long and when to turn on the low light level courtesy light and whether to initiate the functions by motion, touch or time, among others.
Therefore, according to one aspect of the invention, there is provided: an apparatus for dispensing toilet tissue, comprising: a housing; a heating element located on or within the housing and proximate the toilet tissue; a germicidal lamp within the housing, and arranged and configured to irradiate the toilet tissue; and a control device operatively connected to the heating element and the germicidal lamp, the control device enabling operation of the heating element and the germicidal lamp.
Further in accordance with some embodiments, the aspect of the invention described in the previous paragraph further includes one or more of the following additional features: wherein the toilet tissue is rotatably mounted within at least a portion of the housing and the housing includes a first void through which the toilet tissue is dispensed; wherein the housing is located above an existing toilet tissue holder, the housing including one or more second voids within a bottom portion of the housing, the heating element includes a fan to direct heated air through the voids and onto the toilet tissue; wherein the control device includes a timer for the heating element and/or the control device includes a timer for the germicidal lamp; wherein the control device includes a microprocessor and memory, the microprocessor being programmable to enable individual user preferences on duration and temperature of the toilet tissue heating and to store the individual preferences in the memory location; further comprising a motion sensor, the motion sensor initiating operation operatively connected to the control switches and arranged and configured to initiate at least one of the heating element and the germicidal lamp; wherein the motion sensor is located on the top of the housing, whereby a user motion triggers the motion sensor with a gesture above the housing; wherein the motion sensor is located on the bottom of the housing, whereby a user motion triggers the motion sensor with a gesture below the housing; and further comprising a courtesy light.
In accordance with still further embodiments, the aspect of the invention described above may further include wherein the control device is arranged and configured to communicate with a smart device and to receive user selected preferences from the smart device related to at least one of the heating element, the germicidal lamp, and the courtesy light. In other embodiments, the heating element is a polyimide heater film. And in still further embodiments, the heating element is mounted on an external surface of the housing.
According to another aspect of the invention, there is provided: a method of dispensing toilet tissue in an ergonomic manner, comprising: transmitting heat to at least the outer layers of a roll of toilet tissue from a heating element located on or within a housing; shining a germicidal lamp on the outer layers of a roll of toilet tissue from a light source located within the housing; and providing a control device, the control device operatively connected to the heating element and the germicidal lamp and enabling a user to selectively operate the heating element and the germicidal lamp.
While the invention will be described with respect to preferred embodiment configurations and with respect to particular components and structures, it will be understood that the invention is not to be construed as limited in any manner by either such components and structures described herein. Instead, the principles of this invention extend to any method and apparatus in accordance with the claims.
These and other variations of the invention will become apparent to those skilled in the art upon a more detailed description of the invention. The advantages and features which characterize the invention are pointed out with particularity in the claims annexed hereto and forming a part hereof. For a better understanding of the invention, however, reference should be had to the drawings which form a part hereof and to the accompanying descriptive matter, in which there is illustrated and described a preferred embodiment of the invention.

The heater 13 warms the toilet paper 12 to a temperature higher than the ambient temperature. Preferably, the time for the toilet paper 12 to be heated to the designated temperature is almost immediate (e.g., within several seconds) or may be based on pre-planned usage. In order to preserve battery life, preferably the heat function is not continuous. However, use of the optional AC power 17 enables more continuous operation and for use in commercial or other high use environments.
The heater 13 may be based on a number of different types of heating. A preferred embodiment uses heat transfer by thermal convection or radiation but the heater 13 may use conduction methods as well. In addition to the heat generation element, a fan mechanism may be provided to concentrate and direct heated air to the target area (e.g., the toilet paper 12). Internal structural elements within the housing 11 may be included to further focus heated air to the outer plies of the toilet paper 12. Depending on the housing material, a heat shield may be utilized to protect the housing 11 and shield the housing 11 from becoming hot to a user's touch.
In one embodiment the heater 13 uses convection heat where the heater 13 comprises a coil energized by the battery 16 (or other source). Preferably, the toilet paper 12 is heated to between 100 degrees F. to 120 degrees F. (i.e., corresponding to 25-50 degrees F. above a typical ambient temperature). The heater 13 heats the air surrounding the coil and the air is then directed to heat the targeted toilet tissue 12. In another embodiment, the heating component utilizes conduction, with a mode using infrared heating. Here the heat generating components are targeted at the toilet tissue 12. Targeted air may also be used in this embodiment to spread heat more evenly at the intended target. In one embodiment, use of targeted air may function to rotate the toilet paper 12 in order to more uniformly heat the toilet tissue 12 and/or to dispense the same to a user. The timing and air trajectory may be adjusted in order to dispense an optimal amount.
In yet another embodiment, the heater 13 may include a polyimide heater film. It will be appreciated that such heater film includes a polyimide as an outer insulator and a thermos foil as an inner electric heating element. The insulator and heating elements are then sealed using high temperature and high pressure. Advantages of using polyimide film include it being thin, light weight and flexible. This type of heater may operate at 12V DC and include an adhesive film on one side to locate and place the film at a desired location. Such heaters are commercially available, for example under model designation 988704 and manufactured by Icstation of Shenzhen, China.
It will be appreciated by those of skill in the art that sensors and limits may be employed to communicate with the various controls. For example, timers, thermal controls, temperature testing, etc. may be used. More specifically, in the event that various types of devices are utilized as part of the heater 13, a temperature sensor and/or a controller device may be employed to control the heat output.
The germicidal lamp 13 is intended to sterilize the toilet paper 12 and may comprise an ultraviolet C (UVC) light or lights. In some embodiments, multiple lights may be employed to better target the circumference of the toilet paper 12 roll. The germicidal lamp(s) 13 is powered by the battery 16 (or optional AC power 17). It will be appreciated that the germicidal lamp 13 could be either a UV tube lamp(s), UV bulb(s), UB Diode(s), or other UV light sources.
Battery 16 is a preferred power source for the dispenser 10 and is sized and configured to supply power to the various components within the housing 11. Preferably battery 16 is located within the housing 11 to enable removal—either to be recharged or replaced. For example, battery 16 may be accessible through access door 43 and may be interchangeable with one or more similar batteries, such that as one battery charges the other powers the dispenser 10. Battery 16 may also be charged in place by various means such as induction charging or connecting an AC power charger via a connector (not shown) or with optional AC power 17. It will be appreciated that in the case of an AC connection that electrical codes may require distance, ground fault requirements and/or stepping down and converting the voltage to DC.
Controls 15 enable the heater 13 and germicidal lamp 14. Providing input to controls 15 is motion sensor 20, heater on/off switch 18 and germicidal lamp on/off switch 19. It will be appreciated that the external buttons 42 (e.g., buttons or other switches providing user input control) may be preferably located on the exterior of the housing 11 for operation by the user. However, a remote-control panel (not shown) may be utilized. In addition, indicator lamps 41 are provided to assist the user with operation of the dispenser 10.
Motion sensor 20 may operate with a wide range so that a user approaching the dispenser 10 turns on the heater 16 and germicidal lamp 14 for a predetermined period of time and/or based on time preferences. Alternatively, the motion sensor 20 may have a limited range that requires waving a hand directly in front of the sensor 20. The latter embodiment may be preferred in higher volume settings. Further, the external buttons 42 may be utilized by a user to override the motion sensor or to otherwise turn on or turn off the various components.
In some embodiments, preference levels may be set for the various components. For example, the temperature of the heated toilet paper 12 may be adjusted, the components that are turned on by the motion sensor, and/or the amount of time that the components remain turned on may be adjusted. The preference levels may be set by a programmable chip included in the controls 15 or may be set through use of an app on a smart device (e.g., a smart phone). In some embodiments the controls 15 may include a smart device and be connected to an internet, intranet, or close proximity communication (e.g., such as Bluetooth). Further, the operation of the various components, including the charge level of the battery 16, may be monitored as well as other statistics. Accordingly, the controls 15 may comprise a microcontroller and/or microprocessor for the ability to operate and regulate the components within the housing, as well as provide alerts, shut down operations due to malfunction, among others.
Housing 11 provides the structure for the dispenser 10 and houses the various components. As described above, a preferred embodiment housing 11 includes an opening on the bottom through which the toilet paper 12 is dispensed. In operation, the user may grasp the free end of the outermost layer of toilet paper to rotate and dispense the toilet paper through the open bottom. Alternatively, air may be used to rotate the toilet paper or a motor activated by a second motion sensor or “dispense” button (not shown) may be used to engage and rotate the spindle on which the toilet paper 12 is mounted.
