Both the flossing material and flossing material holder are made of a biologically acceptable, biodegradable and preferably digestible material.
2. Background and Related Disclosures
Dental floss, dental floss containers and flossing devices are known in the art and, typically, they are provided in large packaging for multiple uses in the privacy of a home or bathroom. However, in many social situations, the use of these flossing devices is not socially acceptable and would be embarrassing to a user. Consequently there is a need for an unobtrusive single use flossing means.
Additionally, flossing is difficult for children and training children to floss and getting children to floss on a regular basis presents a substantial problem for parents.
The current invention provides a single use, unobtrusive miniature dental flossing packet suitable for use in a social setting without causing embarrassment to the user. The miniature dental flossing packet comprises a small holder for flossing material that can be easily held between a thumb and forefinger of each hand, and easily separated into two portions, thereby releasing the flossing material stored within into its full length. The length of the flossing material is such that it is sufficient to remove food from between the teeth while covering the mouth with both hands. Following the use, the packet containing used flossing material and the holder is rolled into a small easily disposable bundle or, when both the holder and the flossing material are made of edible material, the used packet can be swallowed.
It is therefore a primary object of this invention to provide a simple, inexpensive means for unobtrusive removal of food from between teeth without causing a socially unacceptable embarrassment to an adult user and the means for encouraging children's flossing and flossing training.

I. A Miniature Dental Floss Packet
A miniature dental flossing packet provides a convenient, comfortable and hygienic means for an adult user for removal of food or food debris from between the teeth in social settings. It is small and inconspicuous, easily storable and usable and can be offered in restaurants, hotels, restrooms or carried in the purse, pocket, wallet or be a part of any hygienic kit for travel and instant use. For children's use, it can be used as an incentive for a child's flossing and/or for training small children to floss.
A miniature flossing packet of different shapes ready for use is shown in FIGS. 1A-1D. FIGS. 1A-1C show a side view of three representative shapes of the packet, namely a square, oval or circular packet 10 in their respective assembled form for use. A rectangular shape would be a sideways extended square shape. FIG. 1D shows a side view of a child's ready to use packet having a shape of a teddy bear, but could have a shape of any cartoon character, toy, animal, star, sports ball, or any other shape attractive to children. In addition, any of the shapes of FIGS. 1A-1C can be decorated with attractive designs, including any of the above listed shapes, or patterns or colors for use by adults or children.
The packet 10 is fabricated from two substantially flat and opposing sheets, the front sheet 12, seen in FIGS. 1A-1D, and the same size back sheet 14, seen in FIGS. 2A-2E, forming a front and back side of the packet. The two sheets have essentially the same size and shape and when assembled, form a pocket holding the floss. In FIGS. 1A-1D only the front sheet 12 is visible.
The sheets 12 and 14 are further each divided into two portions 16 and 18 separated by a perforation 32 centered along the axis 22. Thus each packet 10 can be held or gripped by the two portions 16 and 18 and easily separated and torn apart along the perforation 32 by pulling.
FIGS. 2A-2E show a precut sheet or sheets of holder material for fabrication of the miniature flossing packet. The precut may be one piece of material (FIGS. 2A and 2C-2E) that has the two opposed sides 12 and 14 connected at a common edge along the axis 22. Upon assembly, the two sides 12 and 14 are bent or folded over onto each other along an axis 22 that also forms a common edge 22. Alternatively, the packet 10 may be made of two separate sheets 12 and 14 (FIG. 2B) that are assembled together (after the flossing material is attached to each portion). As seen in FIGS. 2A-2E, the sheets or sides 12 and 14 are both perforated with centered perforation 32 such that, upon assembly, the perforation on both sides are joined in one perforation line for easy separation. The perforation 32 separates the sides 12 and 14 into two portions 16 and 18 that are, upon assembly, facing each other. The sheets 12 and 14 are co-joined and attached along their edges 22, 24, 26 and 28, for example, by gluing, pressing, adhesion, sealing or using any other chemical, physical or mechanical method, and form an internal pocket between sheets 12 and 14 for attachment and pre-use storage of the flossing material. FIGS. 2A-2B show the precut material for square packets. FIGS. 2C-2E show the precut material for oval, circular and teddy bear shaped packets.
FIG. 3A shows an unassembled precut sheet defining the two sides 12 and 14 with a pair of attachment points sites 44 for attaching two ends of the flossing material 40 to the two sides of the packet. One end of the floss is attached at a attachment point 44 in portion 16 and the second end is attached at the attachment point 44 in portion 18, both on one side of sheet 12. One side of the sheet 12 wherein the floss is attached is then covered with the sheet 14 and co-joined thereby forming a pocket harboring the stored floss 40. The sheets 12 and 14 both have a perforation 32 that enables easy separation of the assembled packet 10 into two portions 16 and 18, each having one end of the floss attached thereto.
One end of flossing material 40 is thus attached to portion 16 and the other end is attached to portion 18 so that when the two portions are separated by tearing along the perforation 32, the floss material extends between portions 16 and 18 across the perforation 32.
In its storable assembled form, the flossing material is attached to sites 44 inside the pocket created by assembling sheets 12 and 14 into the packet 10 with the excess of the flossing material stored as a flossing material bundle 42. Since FIG. 3A shows an unassembled packet, the flossing material seems to be extended, however, in the assembled form for use, the flossing material will be stored as a bundle or folded between the two sides 12 and 14. In the assembled form seen in FIGS. 1A-1D, the flossing material is not visible since it would be stored inside of the pocket under the sheet 12 of the packet 10. In FIGS. 2A-2E the flossing material has not yet been attached.
For use, the packet 10 is provided to the user, who holds the packet between the thumb and forefinger of each hand, pulls and tears the two portion 16 and 18 from each other thereby releasing the folded or bundled flossing material from its place between the two sheets of the packet. The packet separated into two portions for use is shown generally in FIG. 4. FIG. 4A shows a square packet separated into two portions wherein both ends of the flossing material remains attached to the portions 16 and 18 during the use, providing the user with about 3 to about 10 cm of flossing material that can be easily used while covering the mouth with both hands. The use of the miniature flossing packet thus provide the user with discreet means for flossing without exposing the flossing material.
Due to its miniature size and shape, the packet can be easily disposed of by simply rolling it into a small bundle or swallowing it if the material is digestible.
The miniature packet can be conveniently packaged for hygienic use in the paper cover that may be esthetically ornamental for placement on the table in restaurants, homes, hotel rooms, restrooms or carried in the purse, wallet, pocket or in a travel or hygienic kit.
II. Fabrication of a Miniature Dental Floss Packet
A miniature dental floss packet is fabricated using a method of the invention. The method basically comprises of several process steps, consisting of selecting suitable materials for both the holder and the floss, preparing the floss holder, attaching the floss to the floss holder and assembling the miniature dental floss packet.
A. Flossing Material Holder
The flossing material holder may be made of a single material or two different materials processed or molded into a sheet. Such material may be a paper, cellophane, foil, film, foam polymer sheet or any other material that is thin, pliable, biodegradable and preferably digestible and edible. The material used for fabrication of the holder may be flavored or unflavored. Also, a surface of the dental floss holder may be decorated with any design to make it attractive to be placed on the table or it may be decorated with a cartoon figure, animal, toy, star, ball or any other design that is attractive to children.
The holder is typically prepared from a biodegradable and preferably edible materials that are suitable to be produced in flat form, such as laminar sheets, wafers, films or foams made of or containing edible grade cellulose or other food grade cellulosic material, triglyceride material, collagen, gelatin, polypropylene, proteins, starch or any other edible material as may be conveniently used for preparation of the holder, each alone or in combination. In alternative, the material may be a composite of an edible film, foam, wafer or laminate sheet further covered with another edible material.
The selected material is precut into a single sheet or two sheets having a size and shape of the holder, having, typically, a square, rectangular, circular, tubular or oval shape as illustrated generally in FIG. 2. In alternative, it may have a shape of a cartoon figure or a toy.
Typically, each sheet is perforated in the middle before the flossing material is attached or affixed thereto, as seen in FIG. 2 to permit easy separation of the two portions for use. However, such perforation may also be made after the floss is attached provided that the care is taken to preserve the integrity of the flossing material.
The flossing material is then attached to two portions of the packet as illustrated generally in FIG. 3 showing an unfolded two sheets 12 and 14, each having two portions 16 and 18. After each end of the flossing material is attached to the two portions of the holder, the two sheets are folded over each other thereby forming a pocket completely hiding, concealing and sheltering the bundled or folded flossing material.
The method thus comprises a) selection of a length of dental floss, b) forming a dental floss holder separable, along a line extending between the pair of attachment points for a floss, into two separate portions that can be gripped as tabs by a user to utilize the dental floss extending between the two tabs, wherein said two portions are separated by perforating said holder along the line along which the holder is separable to facilitate tearing, as described above, c) attaching two ends of the dental floss to said holder at a pair of attachment points, and d) joining a pair of substantially flat opposed sides of the two sheets together along the edges after the two ends of the length of dental floss have been attached to one of the sides.
B. Size of the Miniature Floss Holder
Size of the flossing material holder is such that is provides for comfortable use and yet is inconspicuous when used. Typically, the size of the holder, before use, is from about 1.5-3 cm in width and about 1.5-5 cm in length.
C. Flossing Material
Flossing material suitable for preparation of dental floss is any suitable material for use as a dental floss. Dental floss is generally made out of polymeric synthetic compounds. Such materials are typically biologically acceptable materials such as nylon, Teflon, polyamide, polyethylene, high density polyethylene, polytetrafluoroethylene, chitosan, alginate, silk or cotton, each able to be produced as a fiber, string, thread, strand or filament. For example, nylon is defined as a fiber-forming substance of a long-chain synthetic polyamide. A polyamide is a polymerizable compound characterized by more than one amide group. Teflon is the polymerized polytetrafluoroethylene. The flossing material is preferably biodegradable, digestible and/or edible.
D. Attachment of the Floss to the Holder
The flossing material can be attached to the holder material by mechanical, chemical, physical, electrical or any other means known in the art. Such means may be, for example, gluing, adhesion, pressing, sewing, stitching, chemical or physical attachment.
E. Length of the Flossing Material
The flossing material has a reasonable length to permit its use for easy and convenient food removal. The length cannot be too short as it must permit the floss manipulation but it also cannot be too long as it might become entangled, knotted, etc., that would defeat the purpose of the invention.
Consequently, the length of the floss is between about 3 to about 10 cm, preferably between 4 and 7 cm and most preferably about 5 to 6 cm. For use by children, the length of the floss is between 3 and 8 cm, preferably between 4 and 7 cm and most preferably about 5 cm, when unfolded for use.
III. Use of the Miniature Dental Floss Holder
The miniature dental floss packet is used in the manner described above. The user, typically, picks up the packet with thumbs and forefingers of both hands, pulls on two outer portions of the packet, tears the packet into two portions along the perforation, and pulls the two portion from each other thereby releasing the folded floss and uses it to remove the food from between the teeth with the floss hidden behind the users hands. After flossing, the user rolls the packet into a small bundle and discretely disposes of it. In case when both the holder and floss material is digestible, the user can swallow the used packet without any detrimental health and safety effects.
