The present invention relates generally to devices for cleaning teeth and to processes for using same. Specifically, the present invention relates to portable tooth cleaning devices that allow for discreetly cleaning one's teeth when conventional tooth cleaning products and/or water are unavailable or inconvenient as well as the use of those devices.
Good dental hygiene is advantageous for health and cosmetic reasons. Various means exist by which individuals may clean their teeth. The vast majority of tooth cleaning devices are designed consistent with in-home use. For example, conventional tooth brushes are large enough to fit conveniently within a fully clenched hand and have bristles exposed to the open air. Storage of these devices requires containers that are several inches in length and more than one or two inches in diameter. The large size of conventional tooth brushes provides a durable and reusable product that may be used numerous times before the device is substantially degraded to the point necessitating disposal. Although the large size and durability of conventional tooth brushes render them well suited for repeated home use, these characteristics make them inconvenient when away from home or “on-the-go.” In addition, water and tooth paste are typically required for the use of conventional tooth brushes, making their use inconvenient or impossible when water and tooth paste are not readily available.
Various other means have been created in attempts to address the need for a more portable tooth cleaning device. For example, U.S. Pat. No. 6,397,860 discloses a disposable, waterless tooth brushing assembly that includes a toothbrush, a non-foaming, saliva-activated, oral care composition pre-applied to the bristles of the toothbrush, a small moistened disposable towel for use after tooth cleaning, and a compact, lightweight, two-layer heat-sealed packaging container for pre-use sanitary storage of the toothbrush and towel.
U.S. Pat. No. 7,182,542 discloses a waterless disposable toothbrush that includes a handle having a toothpick connected thereto to enable cleaning between teeth, and a rupturable dispenser containing a dentifrice and being connected in a bristle portion of the toothbrush head for dispensing the dentifrice to the teeth.
U.S. Pat. No. 7,478,959 discloses an oral care toothbrush that includes a head mounted to one end of the handle containing a plurality of oral care elements. An oral care accessory is mounted to the opposite end of the handle. An oral care composition dispenser is mounted to the head within the cleaning field defined by the oral care elements.
U.S. Pub. No. 2011/0239387 discloses an oral care toothbrush that includes a handle having a head at one end of the handle, the head having at least one cleaning element and at least one oral care dispenser. The oral care dispenser releases the oral care matter within about five seconds when exposed to water.
Various packaging methods have also been created in an attempt to conveniently house portable tooth cleaning devices. For example, U.S. Pub. No. 2010/0230312 discloses a package for displaying a plurality of items where the package has first and second containers connectable between an open position and a closed position, each container having an outer surface having at least one elongated protrusion, with the head end extending further outwardly from the package than the tail end. The head end of the at least one protrusion of the first container is proximate to the tail end of the at least one protrusion of the second container in the closed position.
Portable tooth freshening and cleansing devices are becoming more common. For example, “portable” concentrated mouthwash strips have become popular among those who are concerned with dental freshness.
Gum products have also tried to capitalize on the desire to clean teeth while on the go. Many modern chewing gum manufacturers market at least one significant line of chewing gum as “whitening” or “dental cleaning” gums.
In an effort to cosmetically improve tooth appearance, consumers have increasingly turned to tooth bleaching or whitening. There are many commercially available methods for whitening teeth, such as brushing, bleaching strips, bleaching pens, bleaching gels, laser bleaching, and natural bleaching. Traditionally, at-home whiteners use overnight trays containing a carbamide peroxide gel which reacts with water to form hydrogen peroxide. Some whitening techniques may undesirably open dentinal tubules causing increased tooth sensitivity and potentially resulting in temporary tooth stains after drinking certain dark colored liquids such as coffee, tea or red wine.
In view of the foregoing, the need exists for compact, ready-to-use tooth cleaner and freshener devices that may be used quickly and discretely in social settings preferably without the need for additional material such as separate tooth paste, cleanser or water. The need also exists for portable and discrete devices for removing dental stains and, in particular, for removing temporary tooth stains resulting from dark colored liquids. The need also exists for improved packaging for such tooth cleaning devices that allow the tooth cleaning devices to be kept clean and fresh until time for use.
In one embodiment, the present invention is directed to a tooth cleaning device, comprising a substantially planar base having opposing first and second sides; a grip member extending proximally from the first side; a plurality of first bristles attached to and distally extending from the second side; optionally a plurality of second bristles attached to and distally extending from the second side; and an oral care composition disposed within a housing or on the first bristles.

The optional second bristles may be attached in rows along the one or more perimeter edges of the distal side of the device. In one embodiment, the device comprises at least one row of second bristles, e.g., at least two rows, at least three rows, or at least four rows. For example, in one embodiment, second bristles are provided in parallel rows on the base, but on opposing perimeter edges. In one embodiment, the base has a lateral cross-sectional shape having four perimeter sides, wherein a first pair of parallel sides oppose one another and a second pair of parallel sides oppose one another, and wherein a first perimeter side area comprises the first pair of sides and a second perimeter area comprises the second pair of sides. In this embodiment, the central region may be disposed between the first pair of sides and the second pair of sides. In a preferable embodiment, the first bristles are disposed along the first perimeter area of the base, and the second bristles are disposed along the second perimeter area of the base. The second bristles may also be provided in perimeter rows along the entire perimeter of the base.
The optional second bristles may be cylindrical in shape with a flat tip or may have a conical shape or other shape, so long as the second bristles are otherwise distinguishable in some respect from the first bristles. The second bristles may be the same color as the first bristles or may be a different color. In one aspect, the second bristles are formed of the same material as the first bristles, but have a different shape, color or angle (relative to the base), or other distinguishing characteristic from the first bristles. In another aspect, the second bristles are formed of a different material than the first bristles, and may or may not have the same shape, color or angle as the first bristles. In some embodiments, the second bristles are comprised of the same material as the first bristles. In other embodiments, the first bristles are made from a different material than the second bristles. For example, the second bristles may be made of a thicker material than the first bristles, or vice versa, but also preferably formed of a material selected from plastic, polypropylene, silicone, nylon, and combinations thereof. Additionally or alternatively, the second bristle may vary in length, color or angle from the first bristles.
In addition to the second bristles, any combination of additional bristles may optionally be included, e.g., third bristles, fourth bristles, etc. Each of these additional types of bristles may differ in a physical characteristic from the first bristles and/or second bristles in any of the above-described ways that the first and second bristles may differ, e.g., length, arrangement, cross-sectional shape, or material.
It is to be understood that the specific illustration of the bristles is merely for describing one non-limiting embodiment of the present invention. The invention can, however, be practiced with various combinations of the same or different bristles configurations. It is thereby possible to select the combination of bristle configurations, bristle materials and bristle orientations to achieve specific intended results, such as enhanced cleaning, tooth polishing, breath freshening, tooth whitening and/or massaging of the gums.
In a first embodiment, shown in
In a second embodiment, shown in
In one aspect, shown in
Tab 19 is preferably removable by the user, e.g., by twisting, bending, snapping, back and forth motion, breaking or other digital action. Removal of the tab creates an opening in the housing, through which the oral care composition may be dispensed by the user, preferably by squeezing the housing between the user's fingertips but optionally otherwise by application of pressure or force. The capsule preferably includes a conduit channel 20 and contains one or more perforations for facilitating tab removal. In the embodiment shown in
In preferred embodiments, capsule 17 is held in place by a plurality of prongs 21. These prongs extend from the grip member to create a rim about the proximal boundary of the capsule, which secures the capsule in the device by frictional forces. The prongs may take the form of one singular prong that is circumferential about the proximal boundary of the capsule, or it may take the form of a plurality of smaller prongs that do not surround the proximal boundary of the capsule, e.g., two prongs (shown) 13a/13b, three prongs, or four prongs.
In preferred embodiments, capsule 17 is replaceable. In these embodiment, the capsule may be removed from its position in the grip member, preferably through the opening at proximal end of the grip member formed in the space between the plurality of prongs but optionally through any other opening in the device. A new capsule containing the oral care composition may then be inserted into the device. This would allow for the user to make repeated use of the same device.
In a third embodiment, as exemplified in

In some embodiments, the plunger locks into place when fully depressed into the second position. This may be accomplished by a plurality of prongs within the cavity that hold the bottom portion in place, a plurality of prongs within the grip member that hold the top portion in place, and/or by any other convenient means.
In another embodiment, the invention is directed to a packaging device for storing and transporting any of the above-described tooth cleaning devices. The packaging device comprises a substantially rigid sleeve 71 and an insert 79, slidably engaged therewith, optionally containing multiple tooth cleaning devices 1. The sleeve preferably is formed of a paperboard or plastic material having a rectangular cross-section and configured for mating with the insert, as shown in
Insert 79 preferably comprises a housing, preferably formed of a plastic material, having multiple cavities, each for housing a respective tooth cleaning device. Each tooth cleaning device is individually sealed within the insert. A sealing material, preferably formed of a metallic foil, is adhered to the housing, optionally by an adhesive or fusing, and covers the multiple cavities such that the tooth cleaning devices are securely stored therein. Upon application of pressure to the housing in the region of a cavity, for example by a user's finger, a tooth cleaning device breaks through the sealing material and into the user's hand for subsequent tooth cleaning.
The insert is slidably engaged with the sleeve between a first position and a second position. In the first position, the insert is substantially fully contained within the sleeve. Preferably, dispensing of the tooth cleaning devices is restricted or prevented when in the first position. In the second position, as shown in
Insert 79 preferably is formed of a housing 72 comprising a plastic material, preferably in the form of a sheet that defines a plurality of cavities 77, each for housing a respective tooth cleaning device 1. The housing also comprises a sealing material 74, preferably a foil sheet, adhered to housing 72 and covering each of the cavities. An adhesive, not shown, may be used at the interface 75 between housing 72 and sealing material 74. The housing may be opaque, translucent, substantially clear or clear. The housing is shaped to include a plurality of cavities, allowing for placement of each of the individual tooth cleaning devices within a respective cavity for individual storage. The foil is optionally perforated around the perimeter of the each tooth cleaning device cavity to facilitate dispensing thereof. This allows for easy separation of individual tooth cleaning devices from the insert without disturbing the seal of the remaining devices in the package. The tooth cleaning devices can be released from the insert by application of pressure by a user to the outside of the plastic cavity that houses a tooth cleaning device, thereby forcing the tooth cleaning device through the sealing material on the opposite side of the insert.
In another embodiment, the invention is directed to a process for using any of the above-described tooth cleaning devices. In one aspect, for example, the process involves the use of a device of the type above described and shown in
In a second aspect, for example, the process involves the use of a device of the type described above and shown in

The disposable tooth cleaning devices of the present invention advantageously provide many benefits, including the cosmetic benefits of cleaning one's teeth while “on the go,” without a toothbrush and/or toothpaste or without a source of water. The cosmetic benefits achieved by the present invention include the broad surface cleaning of one's teeth with the matrix material(s), e.g., sponge, and/or bristles, breath freshening with the oral care composition, and the cleaning of debris between teeth with bristles and/or one or more matrix materials.
As discussed above, the tooth cleaning device preferably comprises an oral care composition. The oral care composition may be impregnated, coated, layered, or otherwise preloaded into or onto the device. An exemplary oral care composition is disclosed in U.S. Pat. No. 8,715,625, which is incorporated herein by reference in its entirety. Unless otherwise stated, amounts listed in percentage are in weight percent (“wt. %”), based on the total weight of the composition.
The oral care composition may comprise one or more of the following: carriers, cleaning agents, surfactants, thickening agents, buffering agents, whitening agents, sweeteners, and/or flavorants.
As in many commercially available oral care compositions, an inert carrier may be the primary ingredient in the oral care compositions. The amount of the carrier in the overall oral care composition may vary from 30% to 75%, e.g. from 35% to 70%, from 40% to 60%, from 50% to 75%. The common inert carrier is water. Other examples of carriers may include sorbitol, glycerol, vegetable glycerin, and combinations thereof.
The cleaning agent, optionally a cleaning solvent, may be used to remove stains from teeth and should be orally acceptable (non-toxic). The amount of the cleaning agent in the overall oral composition may vary from 0.1% to 5%, e.g., from 0.1% to 3%, 0.5% to 3%, from 1% to 4%. Preferably, the cleaning agent is water miscible and hydrophilic. Without being bound by theory, the cleaning agent preferably improves the wetting properties of the overall oral care composition to allow for better penetration of the tooth surface and thereby improved stain removal. Examples of cleaning agents include water, deionized water, purified water, ethanol, glycerol, propylene glycol, PEG-60, PEG-400, PEG-600, benzyl alcohol, methyl salicylate, phenol, acrylic acid, orange oil, acetic acid, vinegar, acetone, formic acid, methanol, propanol, ethanolamine, lactic acid ethyl ester, propionic acid, diethanolamine, triethanolamine, diethylene glycol, diethylamine, triethylamine, tetraethylene glycol, formaldehyde, 1-octanol, and mixtures thereof. In some embodiments, the cleaning agent comprises water and/or ethanol.
The amount of optional surfactant in the overall oral composition may vary from 0.1% to 5%, e.g., from 0.1% to 3%, 0.5% to 3%, from 1% to 4%. The surfactant may comprise non-ionic surfactants, cationic surfactants and/or anionic surfactants. Examples of surfactants include sodium lauryl sulfate (SLS), sodium-N-lauroyl sarcosinate, Pluronic F68, Pluronic F88, poloxamer 188, poloxamer 124, poloxamer 338, poloxamer 407, dioctyl sodium sulfosuccinate, ethylene oxide polymer, polyethyloxylated castor oil, cremophor 40, hydrogenated castor oil, and mixtures thereof.

Anionic and amphoteric surfactants may include, but are not limited to, derivatives of aliphatic secondary and tertiary amines in which the aliphatic component may be a straight chain or branched. The aliphatic substituents may contain from about 8 to about 18 carbon atoms and one may contain an anionic water-solubilizing group, e.g., carboxylate, sulfonate, sulfate, phosphate, phosphonate, betaines (e.g., cocamidopropyl betaine), or a mixture thereof. Many of these nonionic and amphoteric surfactants are disclosed in U.S. Pat. No. 4,051,234, which is incorporated herein by reference in its entirety.
Cationic surfactants that may be useful in the oral care composition may be broadly defined as derivatives of aliphatic quaternary ammonium compounds having one long (e.g., C8-18) alkyl chain. The cationic surfactant may also act as a germicide. Examples of cationic surfactants include lauryl trimethylammonium chloride, cetyl pyridinium chloride, cetyl trimethylammonium bromide, di-isobutylphoxyethyl-dimethylbenzylammonium chloride, coconut alkyltrimethylammonium nitrite, and those described in U.S. Pat. No. 3,535,421, the entirety of which is incorporated herein by reference.
Additional surfactants may include sodium carbonate (anhydrous), sodium bicarbonate (baking soda), potassium iodide, and mixtures thereof. In one embodiment, the surfactant is a combination of a block co-polymer of polyoxyethylene and polyoxypropylene, e.g., poloxamer 407, and hydrogenated castor oil.
A buffering agent may be used to adjust the pH of the oral care composition. The amount of the buffering agent in the overall oral composition may vary from 0.1% to 5%, e.g., from 0.1% to 3%, 0.5% to 3%, from 1% to 4%. Preferably, the amount of buffering agent will be sufficient to adjust the pH of the oral care composition to an acceptable range, e.g., from 4 to 9, from 5 to 8, from 6 to 8. Examples of buffering agents include potassium hydroxide (KOH), ammonium hydroxide, sodium citrate, sodium bicarbonate (baking soda), sodium hydroxide, calcium hydroxide, calcium phosphate tribasic, dipotassium phosphate, sodium monobasic phosphate and sodium dibasic phosphate (optionally anhydrous), sodium aluminum phosphate, sodium tripolyphosphate, sodium benzoate, acetic acid, sodium acetate, citric acid, sodium citrate, benzoic acid, sodium hexametaphosphate, and mixtures thereof.
Thickening agents may be used to adjust the viscosity of the oral care composition. The amount of thickening agents in the overall oral composition may vary from 0.1% to 5%, e.g., from 0.1% to 3%, 0.5% to 3%, from 1% to 4%.
