BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention is related to the field of sanitary disposable articles and, more particularly, to a sanitary disposable writing instrument, a method of making such writing instrument, and a dispenser therefore, to prevent cross-contamination of bacteria, viruses and/or chemicals from one person to another in public locations.
Numerous studies have been performed to determine the levels of bacteria or microbes found on commonly used products. It has been found that one of the highest levels of bacteria can be found on writing instruments used by the public in medical environments such as doctors offices, medical clinics or hospitals, or other high traffic areas such as hotels, cruise ships, banks, restaurants, stores and the like. In medical environments, when a patient is signing the register or writing down his/her medical history, patients who are usually ill, commonly use the same writing instrument. Transference of bacteria, viruses and/or chemicals can occur between medical personnel amongst themselves, as well as, with other patients. In other public environments, such as hotels, restaurants, or banks, people, who may have a cold or the flu, commonly use the same writing instrument. Thus, cross-contamination of germs from one person to another is very common.
In an article entitled “The Cold Wars” in the December 2005-January 2006 edition of Real Simple magazine, the author states that as a means of preventing colds and the flu, one should “keep hands clean by avoiding well-handled objects like the pens at banks and restaurants (bring your own)”. Papermate® has also recently developed a product called the FlexGrip® Elite which is a pen having anti-bacterial protection. This product is being marketed as a device to “Guard Against Gross” which is supposed to keep the pen's surface bacteria free.

DETAILED DESCRIPTION OF THE INVENTION
Before describing the invention in detail, the reader is advised that, for the sake of clarity and understanding, identical components having identical functions have been marked where possible with the same reference numerals in each of the Figures provided in this document.
Referring now to FIGS. 1-2 and 5-6, there is shown the sanitary disposable writing instrument, generally indicated as 10, for reducing the transfer of bacteria, viruses and/or chemicals from one person to another. The sanitary disposable writing instrument 10 comprises a strip of flexible holding material 12 having a predetermined size and shape. The strip of holding material 12 may be formed from any well known material such as paper, plastic, neoprene, and the like. The strip of holding material 12 has a first portion 14 and a second portion 16. A writing implement 18 having a first end 20 and a second end 22 is provided. The first end 20 of the writing implement 18 extends along and is secured to the first portion 14 of the holding material 12. This writing implement 18 is secured to the holding material 12 by any well known means such as adhesive, fusion, and the like. The second end 22 of the writing implement 18 extends beyond and in a perpendicular direction with respect to an edge 24 of the holding material 12 to form a writing tip 26. A writing means 28 is associated with the writing tip 26. Any well known writing means may be employed as the writing implement 18, such as a pen, pencil, marker, and the like. Preferably the writing implement 18 comprises a hollow tube and the writing means comprises either an ink source or graphite filled member, which is capable of being inserted within the hollow tube. A grasping means 30 is formed from one of the second portion 16 and the first portion 14 of the holding material 12. This grasping means 30 acts as an anchor and enables a user to grasp one of the first portion 14 and the second portion 16 of the holding material 12 within his/her hand and write with the writing tip 26.
According to a first embodiment, as illustrated in FIGS. 1-2, the first portion 14 of the holding material 12 can comprise a first edge area 32 of the holding material 12 and the second portion 16 of the holding material 12 can comprise a second edge area 34 of the holding material 12. A securing means 36, such as a pressure sensitive adhesive, can be provided along the second edge 34 of the holding material.
The sanitary disposable writing instrument may be prepared for use by several methods. The first of these methods are shown in FIG. 4A wherein the second edge area 34 is rolled up into a cylinder 38 to enclose the writing implement 10 therein and to form an area for the user to grasp the instrument. The second edge area 34 is secured by means of the pressure sensitive adhesive 36. The second method of preparation is shown in FIG. 4B. This method can be employed for users who are in a hurry and may only need to use the implement to write something quick, such as signing their name. In this method, the user simply folds the second edge area 34 onto the first edge area 32 to enclose the writing implement and form the grasping means 30. Again, the pressure sensitive adhesive 36 provided on the second edge area 34 secures the second portion 16 of the strip 12 to the first portion 14.
As shown in FIG. 4C, a modification may be made to the sanitary disposable writing instrument wherein the first portion 14 of the holding material 12 comprises a first edge area 32 of the holding material 12. This first edge area 32 of the holding material 12 is capable of being one of folded and rolled to enclose the writing implement 18 and to form the grasping means 30. The second portion 16 of the holding material 12 is removable from the first portion by means of a frangible and/or perforated area 39 extending between the first 14 and second 16 portion. This second portion 16, which can be removed from the first portion 14, can be in the form of a coupon or advertisement 41 that the pen user may remove from the sanitary disposable writing instrument. Note that although the pressure sensitive adhesive would not be available for securing this first portion 14 in place, this first portion 14 of the holding material 12 can be held by the user simply by the action of writing with the instrument 10. This advertising product could supplement the cost of the disposable writing instruments and provide a novel technique for store, restaurant, and hotel owners to advertise their product as well as reduce their cost of purchasing the disposable writing instruments 10.
As shown in FIG. 3, at least a second writing instrument 10 may be secured thereto to form a series, generally indicated as 40, of sanitary disposable writing instruments 10. This series 40 of sanitary disposable writing instruments 10 are preferably secured to one another by means of the pressure sensitive adhesive strip 36 which runs along the second edge area 34 of the holding material 12.
According to an alternative embodiment, as illustrated in FIGS. 5-6, the strip of holding material 12 can comprise a pair of layers 42, 44 and the writing implement 18 is enclosed and sealed between these layers 42, 44. These layers may be sealed by any well known means, such as adhesive, plastic fusion, and the like. As shown in FIGS. 7A and 7B, the first portion 14 of the strip 12, which holds the writing implement 18, can either be an edge portion 46 or a center portion 47.

With continuing reference to FIG. 20, the combination dispenser and holding member 300 can include a removable lid 150, also formed from any well-known material, adapted for closing the top opening 132 of the holding member 130.
FIG. 21 shows an outer perspective view of a combination dispenser and holding member, generally indicated as 400, for dispensing a series of sanitary writing instruments 200 according to another design of the present invention. This design is particularly useful for placement on a horizontal surface, such as a desk top or a sign-in window, such as at a doctors' office, or a counter, such as at a bank, hotel, or check-out line.
With continuing reference to FIG. 21 and with reference to FIGS. 21A, 22 and 22A, the dispenser, generally indicated as 160 comprises a container 162 for holding the series of writing instruments 200. The container 162 at least partially encloses the series of writing instruments 200 so as to minimize contamination the writing instruments 100. As discussed above, the container 162 can be formed from any well-known, disposable material, such as cardboard or flexible plastic material to form a sleeve-like enclosure for containing the series of writing instruments 200. The container 162 includes an opening 163 extending therethrough for feeding the writing instruments.
A lid 194, which can be removable, can be provided having a top open portion 164 extending through a top portion 166 of the lid 194. This top open portion 164 is aligned with the opening 163 and is adapted for feeding the series of writing instruments 200, one at a time, there through to allow a user to remove a single writing instrument 100 from the combination dispenser and holding member 400, wherein removal of this single writing instrument 100 positions a subsequent writing instrument 100′ for removal from the combination dispenser and holding member 400. As shown in FIG. 22A, a bottom open portion 168 extends through a bottom portion 170 of the container 160. The bottom open portion 168 is adapted for receiving a biasing member therein.
With reference to FIGS. 21B and 22B, a cylindrical holding member generally indicated as 176 is provided having a top portion 178 including an opening 180 extending there through, a bottom closed portion 182, and sidewalls 184 extending between the top portion 178 and the bottom closed portion 182. The top portion 178, bottom closed portion 182 and sidewalls 184 define a space, generally indicated as 186, adapted for receiving the container 162 and adapted for removal of the container 162 during replacement of the container 162. The top opening 164 is provided in the lid 194 and is in alignment with opening 163 in the container 162 such that one can access and/or remove the individual writing instruments 100 from the series of writing instruments 200. Upon depletion of the series of writing instruments 200 from the container 162, the lid 194 can be removed from the cylindrical holding member 176 and the container 162 can be removed and replaced with a new container 162 filled with another series of writing instruments 200.
According to the design shown in FIGS. 22, 22A, and 22B, a biasing member, such as a spring 172, can be associated with the cylindrical holding member 176. This biasing member or spring 172 is adapted for entering within the bottom open portion 168 of the container 162 and applying a biasing force to the series of writing instruments 200. According to one embodiment, the biasing member or spring 172 is attached to the bottom closed portion 182 of the cylindrical holding member. Spring support members 188 as shown in FIGS. 22 and 22B, can be provided for supporting the spring against tilting to one side and also to prevent stretching of the spring. Although the drawings show a spring 172 as the biasing member, it can be appreciated that any known type of biasing member may be used in the present invention.
At least one coil binding stop 190 may be associated with the spring to prevent or stop the downward motion of the container 162 during placement within the holding member, to prevent the spring 172 from entering too far within the container and applying too great of a force to the series of writing instruments 200. The at least one coil binding stop 190 can include a plurality of stop members 190a, 190b, 190c, and 190d positioned on the inside of the bottom closed portion 182 of the holding member. Alternatively, the at least one coil binding stop 190 or plurality of coil binding stops 190a-190d can be attached to an inside portion of the sidewalls 184 toward the bottom of the holding member 176.
Mounting members 192 may optionally be provided for mounting the combination dispensing and holding member 400 on the horizontal support surface. These mounting members 192 can be in the form of clips, adhesive pads, or any other known type of mounting members. Alternatively, the combination dispensing and holding member 400 may be placed onto the support surface without any type of mounting member. In this design, anti-slip rubber members may be positioned adjacent an outside surface of the bottom closed portion 182 of the holding member 176 to prevent the combination dispensing and holding member 400 from sliding off the support surface.
As stated above, the top portion 178 of the cylindrical holding member 176 can include a removable lid 194 mounted thereon which can be removed to facilitate the replacement of containers 162 therein.
Reference is now made to FIG. 23 which shows a lid 194a, according to an alternative design, which may be used with the combination dispenser and holding member of FIGS. 21 and/or 22. The lid 194a comprises a large opening 164a extending through the top portion 166a of the lid 194a. This large opening would leave the majority of the top portion of container 162 exposed and allow for easy access to the opening 163 extending through container 162 as well as easier access to the writing instrument 100. The lid 194a includes a frame portion 195 which is sized slightly larger than the container 162, and may be shaped differently than the container 162, such as in the size of a hexagon and the like, so as to prevent inadvertent removal of the container 162 from the holding member. A plurality of snaps 196 may be provided for cooperation with the top portion 178 of the cylindrical member 176, as shown in FIGS. 21B and 22B, for securing the lid 194a to the cylindrical member 176.
The holding member 176 can be formed from any well-known material, such as a hard plastic material. The material can be of any color, transparency or translucency and/or include any type of indicia thereon, such as advertising information, holiday décor, decorative designs, and the like.
As discussed in detail above, the invention provides a novel and inexpensive sanitary disposable writing instrument, a dispenser therefore and a method of producing the writing instrument that minimizes the transfer of bacteria, viruses, chemicals and numerous other contaminants from one person to another.
