The present invention pertains generally to disposable sanitary barriers for temporarily covering the hand, and more particularly to a hand protection barrier dispenser for dispensing such barriers.
People today are becoming increasingly mindful of the sanitary conditions of public facilities such as public restrooms. While most people wash their hands after using such facilities, it is common knowledge that many people do not do so. this fact has been established by a number of studies that show that as many as thirty to forty percent of people using a restroom do not wash their hands prior to leaving the restroom. In addition, such studies have also shown that those individuals that do wash their hands, only about half use soap.
Thus, harmful bacteria may often be present on the hands of public restroom users, and such harmful bacteria can be and are left behind on the restroom door handle by such users as they are exiting the restroom. Bacteria can survive sufficiently long to be passed on to subsequent restroom users even though they have washed their hands by touching the door handle as they leave the restroom. Most public restroom users would be happier with the knowledge that they can leave a restroom without picking up bacteria from previous users unwashed hands that may have been left on the restroom door handle.
For years, public restroom users have been improvising ways to exit a public restroom without touching the door handle with their bare hands. For example, such users may use a paper towel or other material to form a barrier with which to grasp the restroom door handle as they exit the restroom. However, paper towels and the like are not necessarily available in all restrooms at all times, and often there is no convenient place near the door for the restroom user to dispose of the used paper towel. Also, the porous material of a paper towel may not provide restroom users with a high degree of confidence that a protective barrier is being provided between their hand and the restroom door handle, especially if their hand and/or the door handle is even slightly wet.
As might be expected, various potential solutions to this problem have been attempted in the past. One such potential solution over this improvised method is described, for example, in U.S. Pat. No. 6,925,763, to Stark et al. The Stark et al. patent provides a tissue dispenser and separate tissue receptacle that are both mounted on or near the door handle of a restroom door. Upon exiting the restroom, a restroom user may easily grasp a tissue from the tissue dispenser, use it to open the restroom door, and dispose of the tissue in the tissue receptacle. Of course, the sheets of tissue used in the Stark et al. patent do not provide a complete hand protection barrier.
At best, such a tissue sheet only provides a barrier for the front surface of the restroom user's hand. To provide even this protection, the restroom user must take a sheet of tissue from the dispenser and manipulate it to a position that covers the restroom user's hand so that no part of the restroom user's hand touches the restroom door handle. Many restroom users using the sheet of tissue do not take the time or care to properly position the tissue to provide an effective protective barrier.
A more complex potential solution to this problem is described in U.S. Pat. No. 4,997,139, to Menard. The Menard patent provides a mechanical dispensing device that automatically dispenses a continuous sanitary covering for a restroom exit door handle. After each use of the door, the mechanical devise advances the sanitary covering to provide a new sanitary covering surface for the door handle. Although this solution may be effective, it is also much more mechanically complex and expensive to implement and is also at least potentially subject to mechanical failure.
Still another potential solution to this problem is described in U.S. Pat. No. 6,912,728, to Panella. The Panella patent provides a hygienic pocket of material that may be placed on a restroom user's hand, and has an adhesive used to temporarily retain the hygienic pocket of material on the restroom user's hand while the door handle of a restroom door is being grasped. The hygienic pockets of material are dispensed from a dispenser that is only minimally disclosed. The hygienic pocket of material consists of two sheets retained together to define the pocket, with the sheet having the adhesive thereupon being longer than the other sheet. Dispensing such hygienic pockets of material that each include adhesive does not appear to be addressed by the Panella patent.
What is desired, therefore, is a simple, inexpensive, and yet effective hand protection barrier dispenser for use by public restroom users and the like to dispense hand protection barriers. The hand protection barriers dispensed by the hand protection barrier dispenser must provide a one hundred percent complete hand protection barrier for substantially the entire hand. The hand protection barrier dispenser for dispensing such hand protection barriers must also be easy and intuitive to use, and reliably implemented.
The hand protection barrier dispenser of the present invention must also be of construction which is both durable and long lasting, and it should also require little or no maintenance to be provided by the user throughout its operating lifetime. In order to enhance the market appeal of the hand protection barrier dispenser of the present invention, it should also be of inexpensive construction to thereby afford it the broadest possible market. Finally, it is also an objective that all of the aforesaid advantages and objectives be achieved without incurring any substantial relative disadvantage.
The present invention takes the form of a hand protection barrier dispenser for dispensing hand protection barriers which may be located at any convenient location. The hand protection barrier dispensed by the hand protection barrier dispenser of the present invention is made of a thin, impermeable material such as plastic that defines a hand protection barrier. The hand protection barriers may be defined by two rectangular sheets that are sealed on three sides and are open on a fourth side, and they may be dispensed from a roll of such hand protection barriers that are perforated to allow a single hand protection barrier to be dispensed at a time. The open fourth side of each of the hand protection barriers may be located adjacent the perforations between each adjacent pair of the hand protection barriers.
Such hand protection barriers provide a user-friendly way for restroom users to exit a public restroom without directly contacting a potentially germ covered restroom door handle. The hand protection barrier dispenser that is used to dispense these hand protection barriers from the roll of hand protection barriers may be mounted on a door, such as a public restroom door, adjacent to the door handle or knob, or on an adjacent wall. The hand protection barrier dispenser could of course also be mounted in other convenient locations where the dispensing of hand protection barriers is desirable. Examples of such other locations include locations in grocery store produce, meat, and bakery departments, as well as at self-service gas stations.
The hand protection barriers are dispensed from a roll of hand protection barriers located in the hand protection barrier dispenser, which has a housing cover hingedly mounted on a housing back that may be mounted on a door, a wall, or some other support. The roll of hand protection barriers are dispensed individually, with a single one of the hand protection barrier being exposed through the housing cover at a time for donning by a user. The exposed hand protection barrier is supported in a position allowing a used to easily access it by slipping the user's hand into it and pulling it from the hand protection barrier dispenser, which action also pulls the next hand protection barrier into position to be dispensed.
The hand protection barrier dispenser preferably operates in a manner allowing only a single hand protection barrier to be removed at a time. A series of rollers adjacent to the roll of hand protection barriers may be used both to place tension on the stream of hand protection barriers as they are pulled off of the roll of hand protection barriers, as well as to allow only a single hand protection barrier to be dispensed at a time. Thus, as a hand protection barrier is pulled from the hand protection barrier dispenser, it will be torn off at the perforations, leaving the next hand protection barrier presented in the position for easy donning.
In another aspect, the hand protection barrier dispenser is arranged and configured to open each of the hand protection barriers as it is brought into position to be dispensed. This may be accomplished wising either or both of two different mechanisms. One such mechanism uses a ruffling roller mounted above a hand protection barrier as it is pulled into position for dispensing. The ruffle roller 104 is supported at an angle causing the bottom edge of the hand protection barrier to be pushed somewhat to assist in opening it. Another mechanism uses a segment of magnetically attractable material on each hand protection barrier near its opening. Magnets mounted in the housing cover attract this segment of magnetically attractable upwardly, opening the hand protection barrier as it moves into position to be dispensed.
It will thus be appreciated that the hand protection barrier dispenser of the present invention may be mounted on or near a restroom door such that it is in a convenient location to dispense hand protection barriers to restroom users as they are about to leave the restroom. Such a hand protective barrier dispenser may be used in other applications, such as in grocery stores in the produce, meat, and/or bakery departments, to protect users' hands from direct contact with meat, fruit, vegetables, and/or bakery products, thereby enabling purchasers to purchase uncontaminated food. The hand protection barrier dispenser of the present invention may also be used at self-service gas stations, to prevent gasoline, oil, or other substances from contacting the user's hands. Still another potential use of the hand protection barrier dispenser of the present invention is use in cleaning pet liter containers.
It may therefore be seen that the present invention teaches a simple, inexpensive, and yet effective hand protection barrier dispenser for use by public restroom users and the like to dispense hand protection barriers. The hand protection barriers dispensed by the hand protection barrier dispenser provide a one hundred percent complete hand protection barrier for substantially the entire hand. The hand protection barrier dispenser for dispensing such hand protection barriers is also easy and intuitive to use, and it is reliably implemented.
The hand protection barrier dispenser of the present invention is of a construction which is both durable and long lasting, and which will require little or no maintenance to be provided by the user throughout its operating lifetime. The hand protection barrier dispenser of the present invention is also of inexpensive construction to enhance its market appeal and to thereby afford it the broadest possible market. Finally, all of the aforesaid advantages and objectives of the hand protection barrier dispenser of the present invention are achieved without incurring any substantial relative disadvantage.
These and other advantages of the present invention are best understood with reference to the drawings, in which:
An exemplary embodiment of the hand protection barrier dispenser of the present invention is illustrated in the figures and may be discussed in conjunction therewith. Referring first to
The housing cover 34 has a large opening 38 that is located therein such that it is accessible from roughly the left half of the housing cover 34 (as best viewed in the cross-sectional view of
Referring now primarily to
Located to the left of the bag roller 52 on the housing back 36 is a timing roller 60 that is also mounted in a vertical orientation. The timing roller 60 is supported by a top timing roller bracket 62 at the top end thereof and a bottom timing roller bracket 64 at the bottom end thereof, both of which are also mounted onto the housing back 36. The bottom timing roller bracket 64 may also be of two-piece construction to allow the installation and removal of the timing roller 60. Alternately, any other suitable construction to allow for the installation and removal of the timing roller 60 may instead be used. The function and operation of the timing roller 60 will be discussed below in conjunction with a description of the operation of the hand protection barrier dispenser 30.
Movably suspended to the left of the centerline of the timing roller 60 is a spring roller 70. The spring roller 70 is supported by one end of a top spring bracket support arm 72 at the top end thereof and by one end of a bottom spring bracket support arm 74 at the bottom end thereof. The other end of the top spring bracket support arm 72 is pivotably supported on the top timing roller bracket 62 about the axis of the timing roller 60, and the other end of the bottom spring bracket support arm 74 is pivotably supported under the bottom bracket 64 about the axis of the timing roller 60. A spring roller biasing spring 76 urges the top spring bracket support arm 72 in a clockwise direction as viewed from the top thereof. Optionally, another the spring roller biasing spring (not shown herein) may be used to urge the bottom spring bracket support arm 74 in a counterclockwise direction as viewed from the bottom thereof. The function and operation of the spring roller 70 will be discussed below in conjunction with a description of the operation of the hand protection barrier dispenser 30.
Prior to discussing the remainder of the components mounted on the housing back 36, a description of the roll of hand protection barriers 50 in conjunction with
The hand protection barriers the hand protection barriers 80 of the present invention are preferably made of a thin, impermeable material such as plastic that defines a hand protection barrier. For example, the hand protection barriers 80 may be made of polypropylene or any other suitable plastic film.
In an optional implementation, each of the hand protection barriers 80 has a segment of magnetically attractable material 88 located on the front side 82 near the opening thereof (shown at a central position adjacent the right side of the hand protection barriers 80 in
Returning now to
The spring roller 70 is biased by the spring roller biasing spring 76 (shown in
As the hand protection barriers 80 come off of the spring roller 70 and extend over the surface of the housing back 36, they are retained in place along the top edge thereof by a continuous sliding track 90 that is mounted on three spaced-apart rollers 92, 94, and 96. The rollers 92, 94, and 96 are respectively mounted above the housing back 36 by three track roller brackets 98, 100, and 102. The sliding track 90 retains the top edge of the hand protection barriers 80 close adjacent the surface of the housing back 36, and allows the hand protection barriers 80 to be pulled to left (as shown in
As the hand protection barriers 80 come off of the spring roller 70 and extend over the surface of the housing back 36, their lower edges move under a ruffle roller 104 that is mounted above the housing back 36 by a ruffle roller support 106. Rather than being oriented about an axis parallel to the movement of the hand protection barriers 80, the ruffle roller 104 is supported by the ruffle roller support 106 at an angle tending to cause the bottom edge of the hand protection barriers 80 to be pushed somewhat upwardly to ruffle it as the hand protection barriers 80 are pulled to the left. The movement will tend to assist in the opening of each hand protection barrier 80 on the right side thereof, and acts to break any static seal that may exist between the front side 82 of the hand protection barriers 80 and the back side 84 of the hand protection barriers 80.
Referring now to
Located on the underside of the housing cover 34 on the bottom side of the angled wall 44 are two magnets 116 and 118. The magnets 116 and 118 extend downwardly over the central portion Of the hand protection barriers 80 as they are pulled to the left from the rollers that are mounted on the housing back 36. The magnets 116 and 118 are spaced above the housing cover 34 sufficiently close to be able to attract the segment of magnetically attractable material 88 on each of the hand protection barriers 80, but sufficiently far to cause the magnets 116 and 118 to pull the segment of magnetically attractable material 88 and the edge of each of the hand protection barriers 80 up to open them as the segment of magnetically attractable material 88 passes below the magnets 116 and 118 (as best shown in

In the preferred embodiment, only a single one of the hand protection barriers 80 is dispensed by the hand protection barrier dispenser 30 at a time. While the perforated connection 86 between adjacent hand protection barriers 80 allows a single hand protection barrier 80 to be torn off at a time, it may be appreciated that if there is no resistance to pulling out more than a single hand protection barrier 80 at a time, more than one hand protection barrier 80 may inadvertently be removed at a time. In order to prevent this from occurring, the preferred embodiment uses the timing roller 60 (shown in
The timing roller 60 is arranged and configured such that it will be effective to allow only a single hand protection barrier 80 to be dispensed at a time, and may contain a mechanism therewithin or adjacent thereto to operate in this manner. It may do so by placing a tension on the stream of the hand protection barriers 80, or by momentarily stopping rotation when the timing roller 60 has been rotated an amount indicating that a single hand protection barrier 80 has been dispensed. Such mechanisms are relatively well known in the art of paper towel dispensers, and thus will not be disclosed herein in detail.
One such example of such a mechanism is found in U.S. Pat. No. 3,647,159, to Bump, which discloses a towel dispenser having automatic towel length controlling means and roll support tensioning means. Thus, the timing roller 60 is arranged and configured to rotate sufficiently far to allow the exposed hand protection barrier 80 to be pulled to the left to the point at which the next hand protection barrier 80 from the roll of hand protection barriers 50 is in position to be dispensed. At this point, the timing roller 60 will momentarily stop rotating, causing the perforated connection 86 between the exposed hand protection barrier 80 and the next hand protection barrier 80 to tear, allowing the removal of the exposed hand protection barrier 80 from the next hand protection barrier 80. U.S. Pat. No. 3,647,159, to Bump, is hereby incorporated herein by reference.
