Definitions
- the present invention relates generally to methods and devices for facilitating maintenance of good oral hygiene. More particularly, the present invention is related to novel instruments for maintaining oral hygiene, and packages and methods for storing and dispensing such instruments
- tongue cleaners are available and are used to scrape debris from the tongue as a separate practice from regular brushing and flossing. Nonetheless, tongue cleaning is perhaps the least practiced of these oral hygiene components. It is currently estimated that only one out of ten individuals clean their tongues each day.
- the tongue serves multiple purposes in the mouth including to taste, to transfer food between teeth during chewing, and to participate in speech.
- a distinctive layer of plaque, bacteria, tongue debris or other material builds on the tongue. Excessive plaque can interfere with taste, and cause bad breath. Mouthwash and mouth fresheners may help to reduce bad breath but they do not eliminate the root cause. Improved habits and devices are thus needed to eliminate that root cause—tongue plaque.
- the flexible bristles on the toothbrush do not provide sufficient resistance to effectively scrape away plaque on the tongue.
- the motion provided by the user may not be sufficiently symmetric about the tongue to cover most of its area.
- the use of a toothbrush to clean the tongue can lead to choking or gagging, especially in children and adolescents.
- the present invention provides a package for dispensing devices for cleaning tongue surfaces.
- the package includes a container having an opening, and a plurality of devices disposed within the container, wherein the devices each include at least one edge adapted to clean tongue surfaces.

- the body or central portion 302 of the device 300 may be deformed to a curved condition across the tongue using the handles 301 .
- the tongue is extended out from the mouth in a generally flat position, which allows for more complete scraping of the tongue with the central portion 302 .
- One or more scraping motions from top to bottom are performed to remove debris.
- the number of scraping motions or repetitions required may depend upon the duration between cleaning of the tongue and the kinds of foods that the individual eats or drinks, as excessively fatty foods may build plaque quicker than other foods. It is expected that at least three such motions will at times be needed to help remove plaque buildup on the tongue. Lesser repetitions may be used if a regular tongue scraping habit is developed. The result of good scraping is evidenced by the exposure of the underlying pink tissue of the tongue and the exposure of the taste buds contained in the numerous papillae on the tongue.
- the device 300 of the invention can be effectively used to clean substantial portions of the tongue without choking or other difficulties such as gagging, with trial and error by the user establishing the most effective and comfortable range of tongue cleaning. For children or adolescents, some supervision may be needed until safe and comfortable habits are established.
- central portion 302 is curved over and in contact with the tongue for effective scraping.
- Central portion 302 is of sufficient length to traverse the tongue and as shown is desirably sufficiently long to space handles 301 from the tongue for effective gripping by the user.
- the user can rinse the invention with water, optionally soapy water, and then use the device again for continued cleaning of the tongue.
- the device 300 may be inverted to use the opposite edge of the central portion 302 in similar fashion for tongue cleaning. The device 300 may then be disposed of after the cleaning operation is complete.

- The present invention relates generally to methods and devices for facilitating maintenance of good oral hygiene. More particularly, the present invention is related to novel instruments for maintaining oral hygiene, and packages and methods for storing and dispensing such instruments
- As further background, conventional oral hygiene practices are designed to protect and maintain in good health and condition three main components—the teeth, gums, and tongue. Brushing one's teeth has become a fairly routine practice in society, with medium to soft bristle brushes being recommended along with toothpaste to remove plaque and food particles on and in between the teeth and gums. Although perhaps less widely practiced, the use of dental floss to clean between the teeth and gums is also a common practice. Current recommendations include such use of dental floss at least once daily to help remove materials which may cause tooth decay and a consequent need for treatment.
- Dental practitioners recommend the use of a regular toothbrush with paste to brush the tongue. In addition, tongue cleaners are available and are used to scrape debris from the tongue as a separate practice from regular brushing and flossing. Nonetheless, tongue cleaning is perhaps the least practiced of these oral hygiene components. It is currently estimated that only one out of ten individuals clean their tongues each day.
- The tongue serves multiple purposes in the mouth including to taste, to transfer food between teeth during chewing, and to participate in speech. In the course of daily eating habits a distinctive layer of plaque, bacteria, tongue debris or other material builds on the tongue. Excessive plaque can interfere with taste, and cause bad breath. Mouthwash and mouth fresheners may help to reduce bad breath but they do not eliminate the root cause. Improved habits and devices are thus needed to eliminate that root cause—tongue plaque. While a substantial percentage of the population may attempt to use a toothbrush to clean their tongue, the toothbrush is not designed for this purpose. The flexible bristles on the toothbrush do not provide sufficient resistance to effectively scrape away plaque on the tongue. In addition, the motion provided by the user may not be sufficiently symmetric about the tongue to cover most of its area. Moreover, the use of a toothbrush to clean the tongue can lead to choking or gagging, especially in children and adolescents.
- While instruments have been proposed that are especially adapted for tongue cleaning, they have typically been inconvenient to use, to clean, and to store. Thus there exist needs for improved tongue cleaning instruments which are convenient to use, store and dispense. The present invention is addressed to these needs
- Accordingly, in one aspect, the present invention provides a package for dispensing devices for cleaning tongue surfaces. The package includes a container having an opening, and a plurality of devices disposed within the container, wherein the devices each include at least one edge adapted to clean tongue surfaces. In accordance with this aspect of the invention, the devices are connected to one another, but are separable from one another at breakaway points in between individual ones of the devices. These devices are dispensable through the opening in the container.
- Another embodiment of the invention provides an article of manufacture that includes a strip having a plurality of devices for cleaning tongue surfaces, wherein the devices each have at least one edge adapted to clean tongue surfaces. The devices are separable from one another at breakaway points on the strip that occur in between individual ones of the devices.
- In another embodiment, the invention provides a device for cleaning tongue surfaces that includes a central portion having at least one edge adapted to clean tongue surfaces. The device includes a first grip portion at a first end of the central portion, and a second grip portion at a second end of the central portion. The first and second grip portions each have a surface having proturbences therefrom to facilitate gripping during use. The central portion of the device is in a curved condition, or is deformable to a curve condition by manipulation of the first and second grip portions.
- Another embodiment of the invention relates to a package for dispensing devices for cleaning tongue surfaces. The package includes a container having an opening, and a strip disposed in the container and containing a plurality of devices for cleaning tongue surfaces. Each of the devices has at least one edge adapted to clean tongue surfaces. The strip is dispensable through the opening, and the package includes a cutting element arranged for cutting the strip to separate devices from the strip.
- In another embodiment, the present invention provides a package for dispensing devices for cleaning tongue surfaces. The package includes a container having an opening. A plurality of devices for cleaning tongue surfaces is disposed in the container, wherein each device has at least one edge adapted to clean tongue surfaces. The devices are dispensable through the opening and are arranged in the container in a fashion wherein dispensing a first device from the opening presents a second device at the opening for subsequent dispensing.
- The present invention is directed to a system with a yoke structure and a tongue scraping ribbon or strip attached thereto. In accordance with the embodiments of the invention the tongue scraping ribbon or strip detachably couples to the arms of the yoke structure and/or the yoke structure detachably couples to a handle portion. Tongue scraping ribbons or strips in accordance with the embodiments of the invention, are made from any number of materials or combination materials, such as plastics and foams. Tongue scraping ribbons or strips are contoured, patterned, textured or shaped in any number of different ways. The tongue scraping ribbons or strips are, in accordance with the embodiments of the invention, coated with and/or include a whitening agent, an anti-bacterial agent, an anti-microbial agent, a flavoring agent or a combination thereof.
- The system in accordance with the embodiments of the invention includes container unit or dispenser unit for dispensing the tongue scraping ribbons or strips from a spool of tongue scraping ribbons or strips. The container unit or dispenser unit, such as described above and below, has any number of different shapes and configuration. Preferably, the container unit or dispenser unit is also configured to dispense floss from a spool of floss that is concentrically position with respect the spool of tongue scraping ribbons or strips.
- In accordance with alternative embodiments of the invention, ribbons or strips that are dispensable from the container unit or dispenser unit, such as described above and below, are formed from gum, gelatine or any other chewable or eatable material or materials and include a whitening agent, an anti-bacterial agent, an anti-microbial agent, a flavoring agent or any combination thereof. Where the ribbons or strips are formed from gelatine, the ribbons or strips are preferably placed along a tooth and gum line within an oral cavity and dissolve to release the whitening agent, the anti-bacterial agent, the anti-microbial agent, the flavoring agent or the combination thereof. Where the ribbons or strips are formed from gum, the strips or ribbons are preferably chewed and release the whitening agent, the anti-bacterial agent, the anti-microbial agent, the flavoring agent or the combination thereof while in the oral cavity.

- With reference now to
FIG. 1 , shown are details of an individual's face with tongue extended in a position typical of a cleaning operation. The individual includes amouth 100 through which solid and liquid nutrients are consumed. Themouth 100 includes several anatomical sites including thetongue 200,teeth 201, and thegums 202. These three parts of the mouth are the most important in terms of oral hygiene. While the shape of the tongue may vary from individual to individual, its main features include the dorsum or upper surface of the tongue body, and the cecum, from which the thyroid gland originates. The dorsum of the tongue has several types of papillae bearing numerous taste buds. These are usually arranged in a V-shape. One type of papillae, called the fungiform papillae, also contains numerous taste buds which help to identify taste, touch, pain and temperature of any materials touching the same. To optimize the sense of taste, touch, pain and temperature, the papillae must be clean and free from plaque deposits that may form during normal eating habits. - With reference now to
FIG. 2 , shown is atongue cleaning device 300 of the invention. Thedevice 300 has twoends 301 which may or may not be identical to one another. Thedevice 300 further includes a body orcentral portion 302 connected to theend portions 301 by aneck region 308. In accordance with the invention,neck region 308 can be either a sharp transition or a gentle radius as shown in the illustrated embodiment. In certain embodiments, theends 301 are wider than the central portion of thebody 302. The ends 301 are used as handles during use of thedevice 300. Further, ends 301 may have extrusions, protrusions orother proturbences 303 on either one end or on both ends 301. The proturbences facilitate gripping by a user of the device, for example between the index finger and the thumb. Such surface gripping features assist in maintaining the user's grasp of the device during an operation wherein the body orcentral portion 302 is passed over the tongue in a scraping motion. In certain embodiments of the invention, typical dimensions of thedevice 300 and similar devices described herein are about 100 millimeters to about 125 millimeters (i.e. about four inches to about five inches) in total length, about 5 millimeters (i.e. about 0.2 inches) in breadth along thecentral portion 308, and less than about 1 millimeter in width (thickness), for example about 0.5 millimeters (i.e. about 0.02 inches) in width. The breadth of the ends or handleportions 301 may be the same as, or vary from, the breadth of thecentral portion 302. Preferably, the breadths of theend portions 301 will be greater than that of thecentral portion 302. It will be understood that these dimensions are illustrative of preferred embodiments and that the dimensions of devices of the invention may vary as determined by ergonomics, manufacturing concerns, and other similar factors. - With reference now to
FIG. 2 along withFIGS. 2A and 2B , as discussed above, thehandles 301 desirably include gripping surface features such as extrusions orprotrusions 303 or other proturbences. It will be understood that the depicted handles 301 and protrusions orextrusions 303 are illustrative in nature, and that they need not be symmetrical about the body orcentral portion 302 of thedevice 300 in accordance with the invention. Such extrusions can be of linear, cross-hatched, oblique or curved design, or any other pattern or configuration that provides for the grip needed between the index finger and the thumb to help in the scraping motion when thedevice 300 is used on the tongue. Additionally, other gripping features on handle portions of the devices may include non-skid laminations or secondary layers adhered to the handle surface, optionally using bonding agents such as medical grade glue. - With reference particularly to
FIG. 2A , shown is a cross-sectional view of the body orcentral portion 302 of thedevice 300. Thecentral portion 302 presents two edges which are configured to be smooth to help prevent injury to the tongue during use of thedevice 300. At the same time, at least one of these edges is radiused or otherwise adapted to present an edge that is effective in scraping debris from tongue surfaces. In one embodiment, both edges of thecentral portion 302 can be so adapted. - Generally, tongue cleaning devices of and used in packages and systems of the invention will be free of any sharp edges or corners that could cause injury to tongue or other tissues during handling and use. Tongue cleaning devices of and used in the invention can be made of any suitable biocompatible material having a ductility and yield strength sufficient to prevent breakage during use, including for example a plastic (e.g. a soft plastic such as silicone) a or metal that is not susceptible to rust. If made of plastic, devices of the invention may be manufactured in various colors and designs. Further, plastic used in tongue cleaning devices of the invention can be impregnated or coated with flavoring agents such as mint, spearmint, bubblegum, fruit flavors, etc., and/or with coloring agents, including the provision of varying color, art design, or patterns on the device, to make the device more appealing to adult, adolescent or child users.
- With reference now to
FIG. 3 , shown isdevice 300 of the invention in use. In particular,device 300 is used in a scraping operation upon the tongue. Typically, thedevice 300 will be used to scrape the tongue in a top to bottom (or back to front) fashion as indicated byarrows 305. The body orcentral portion 302 of thedevice 300 may be deformed to a curved condition across the tongue using thehandles 301. As shown inFIG. 3 , the tongue is extended out from the mouth in a generally flat position, which allows for more complete scraping of the tongue with thecentral portion 302. One or more scraping motions from top to bottom are performed to remove debris. The number of scraping motions or repetitions required may depend upon the duration between cleaning of the tongue and the kinds of foods that the individual eats or drinks, as excessively fatty foods may build plaque quicker than other foods. It is expected that at least three such motions will at times be needed to help remove plaque buildup on the tongue. Lesser repetitions may be used if a regular tongue scraping habit is developed. The result of good scraping is evidenced by the exposure of the underlying pink tissue of the tongue and the exposure of the taste buds contained in the numerous papillae on the tongue. Thedevice 300 of the invention can be effectively used to clean substantial portions of the tongue without choking or other difficulties such as gagging, with trial and error by the user establishing the most effective and comfortable range of tongue cleaning. For children or adolescents, some supervision may be needed until safe and comfortable habits are established. - With continued reference to
FIG. 3 , the illustration assists in understanding the effective design of thedevice 300. As can be seen,central portion 302 is curved over and in contact with the tongue for effective scraping.Central portion 302 is of sufficient length to traverse the tongue and as shown is desirably sufficiently long to space handles 301 from the tongue for effective gripping by the user. After an initial scraping of the tongue, the user can rinse the invention with water, optionally soapy water, and then use the device again for continued cleaning of the tongue. In addition, thedevice 300 may be inverted to use the opposite edge of thecentral portion 302 in similar fashion for tongue cleaning. Thedevice 300 may then be disposed of after the cleaning operation is complete. - Referring now to
FIG. 4 , shown is an article of manufacture including a strip containingmultiple devices 300 of the invention. The strip may contain, for example, fifteen or thirtydevices 300, which can thereby be packaged together. It will be understood that the number of devices in the strip or otherwise packaged together may vary and that systems containing two or more devices for tongue cleaning are considered as within the broader aspects of the invention. - With reference to
FIG. 4A , thedevices 300 are attached in sequence by two or moreslender filaments 307 on the end of afirst device 300 and two or moreslender filaments 306 on an end of asecond device 300, with the filaments made of the same material as thedevices 300. Thefilaments device handle 301.Intentional notches 309, providing breakaway points, are made on theslender filaments filaments area 309. This force to failure helps the user to separate one device of theinvention 300 from the remaining devices of the invention in the strip. These notched and other breakable areas that are relatively weaker against breakage than adjacent areas are contemplated for use in the present invention, including for example thinned wall areas, perforations, scores, or the like. - As explained below, a dispensing packaging system for the devices may also include an adaptation to aid in the separation of
devices 300 from one another. In the illustrated embodiment, thefilaments devices 300 and in particular thehandles 301. Other methods of attachment ofdevices 300 to one another such as removable glue, static attachment, etc., are also contemplated as within the present invention, wherein such attachments can be similarly used in the convenient sequential dispensing or presentation of devices from packages. -
FIG. 5 provides a perspective view of a container orpackage 400 providing a dispensing system for devices for cleaning tongue surfaces. The container orpackage 400 contains features including alid 401,body 402,lid handle 403,closure rim 408, and standinglegs 407.Lid 401 allows the container to be opened and closed as needed, which operation is facilitated by thelid handle 403.Lid 401 helps to prevent dust and other debris from entering and contaminating thedevices 300 stored within thecontainer 400.Lid 401 interacts with thebody 402 and in particular theclosure rim 408 to create a closure seal for such purposes. The standinglegs 407 may be provided in any number or configuration to allow for stable package standing during storage. At the same time, thelegs 407 should not be of a size or dimension that interferes with normal and easy storage of thecontainer 400. - With reference to
FIG. 5A , shown is a cross-sectional view of thedevice 400 ofFIG. 5 taken through the center of the container, generally along the plane defined by line D-D.Lid 401 ofdevice 400 is also cutaway in the view ofFIG. 5A .FIG. 5A shows an interior mechanism by which a dispensing system functions to provide a user withdevices 300 as needed. The internal mechanism includes aspindle 406 which can optionally be placed centrally within thecontainer 400 as shown. Thespindle 406 is free to move about its central axis in a rotational fashion. A strip containing a plurality ofdevices 300 attached together by means ofthin filaments 306 and 307 (seeFIGS. 4 and 4A ) is wound around the spindle. Particularly, the dotted or phantom line indicates the strip containing about fifteen to thirtydevices 300 wound around thespindle 406. Again, it will be understood that the number of devices in the strip may vary from this number in the present invention. The winding ofdevices 300 around the spindle provides a reel ofdevices 300 that can be conveniently stored and dispensed. As discussed further herein below, the plurality ofdevices 300 may be stored in the package and other arrangements including stacking on top of one another or other configurations that provide a convenient, preferably sequential, presentation of the devices for use. - Referring now to
FIG. 5B , shown is a perspective view of the package ofFIG. 5 , withlid 401 cut away. Anend 301 of afirst device 300 is looped through the outlet opening 404 of thecontainer 400. Theoutlet opening 404 may be of optimal shape and size to allow for the easy passage of thedevice 300. Theoutlet opening 404 may be padded with soft material if desired to prevent damage to thedevice 300 during removal. The location of outlet opening 404 may vary depending upon the location needed to provide efficient mechanical dispensation of devices from thecontainer 400. In the illustrated embodiment, theoutlet opening 404 is located on the top right of thecontainer body 402. This provides convenient mechanical action since thedevices 300 are wound about thespindle 406 in a counter-clockwise direction in the view presented. If thedevices 300 were wound about the spindle in a clockwise direction, the outlet could conveniently be placed on the top left corner of thecontainer body 402 in the view presented. As shown inFIGS. 6A and 6B , theend 301 of afirst device 300 is looped through theoutlet opening 404 and passed through the cuttingelement 405. The cuttingelement 405 may be made of a harder plastic material than that of thedevice 300, or made of a metal such as steel that is not susceptible to rust. Cuttingelement 405 may optionally include a knife edge on one of its corners to help the user to separate thedevice 300 fromother devices 300 in the strip at the breakaway notch 309 (seeFIG. 5A ). When used, the knife or other cutting edge may be placed in such a position where the user intends to separate thedevices 300 at thenotches 309 offilaments notch 309 of thefilaments device 300 from the strip in which it is contained. In addition, where cuttingelement 405 is adapted to sever a plastic or other material susceptible to cutting, a plurality of devices may be provided in the strip even where the strip is a continuous or uninterrupted web of material of sufficient length to provide multiple tongue cleaning elements. Thus, breakaway portions or other weakened areas are not necessary in such embodiments of the invention. Preferably, the cutting element is an integral part of thecontainer body 402. In addition, theoutlet opening 404 may include an anti-slip mechanism that restricts thedevice 300 and devices within the container from unintentionally retracting into the body ofcontainer 402 whereby they would be inaccessible or only difficulty accessible to the user. Such an anti-slip mechanism may include the creation of friction between the walls or edges of theoutlet opening 400 and the strip ofdevices 300, or other similar friction mechanisms. Further, thespindle mechanism 406 may include a spring mechanism to provide tension on the strip ofdevices 300 to help in the ease of dispensing and/or preventing retraction of the devices by the user. Suitable spring mechanisms for these purposes are known to those skilled in the art. Where the width ofdevice 300 varies along its length, the design of the outlet and cutting element will take this into account. Further, anti-slip and tension springs on thespindle 406 may help in accommodating such variations while achieving a smooth and convenient dispensing operation. - As discussed above, the
