Dental professionals often use liquid, gelatinous, or paste materials when providing dental care. Such materials include, for example, dental varnish, polishes, fillings, medications, and prophylactic remedies. It is desirable to have convenient access to such materials while administering dental care to a patient. Several devices have been developed that provide convenient access by putting the material directly in the hand of the dentist rather than placing the materials on a nearby tray which would require constant turning and shifting.
Certain devices, while in use, are pressed firmly against the user's finger, which can lead to discomfort. Moreover, such devices possess sharp edges that can damage examination gloves.
Other devices provide a dental care material in a disposable cup that can be snap fit into a reusable, secondary device that may be placed on the user's finger. The secondary device is not intended to be disposable and, therefore, must be sterilized between uses.

The terms “comprises” and variations thereof do not have a limiting meaning where these terms appear in the description and claims.
As used herein, “a,” “an,” “the,” “at least one,” and “one or more” are used interchangeably. Thus, for example, a receptacle that comprises a well can be interpreted to mean that the receptacle includes “one or more” wells.
The term “and/or” means one or all of the listed elements or a combination of any two or more of the listed elements.
Also herein, the recitations of numerical ranges by endpoints include all numbers subsumed within that range (e.g., 1 to 5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, 5, etc.).
Generally, the device (10), shown in
The device (10), generally, may be formed from any suitable material. In embodiments in which one or more materials (e.g., dental care materials) are to be stored in the device (10), the device (10) should be constructed from materials that are compatible with any material to be stored in the device (10). As used herein, a material from which the device (10) is formed is compatible with a material stored in the device (10) if it does not substantially degrade or compromise the effective use of material being stored in the device (10) over typical storage times. Suitable materials from which the device (10) may be formed include, for example, thermoplastic, thermosetting, and foil materials. Suitable materials for the device (10) include, for example, aluminum, polypropylene (PP), polyethylene (PE), polytetrafluoroethylene (PTFE), polyethylene terephthalate (PET), polyacrylamide (PA), polybutylene terephthalate (PBT), polyvinyl chloride (PVC), ethylene vinyl acetate (EVA), polyvinyl fluoride (PFV), and combinations thereof. Suitable foil materials include, for example, aluminum, tin, gold, silver, iron, and combinations thereof. Suitable materials further include, for example, foils that include an SiOx-containing layer. Moreover, the device (10) may include multiple layers of these materials (and/or other materials). For example, the device (10) may include a top layer of polyethylene, an intermediate layer of aluminum film and a bottom layer of polyethylene terephthalate.
The device may be formed using any method suitable for forming the materials described immediately above. Such methods are routine and known to those of ordinary skill in the art. Foil materials may be formed by, for example, rolling, embossing, stamping, etc. Polymeric materials may be formed by, for example, injection molding, thermoforming, vacuum forming (commonly known as vacuforming), etc. Also, combinations of suitable methods may be used, if desired.
In some cases, the device (10) may be a single integrated unit formed from similar—in some cases even identical—material throughout the entire device (10). In other embodiments, one portion of the device (10) may include different materials than one or more other portions of the device (10).
The receptacle (12) generally includes a top surface (14) into which a well (16) is formed. In use, the well (16) can hold, for example, dental care material. The well (16) also may be fashioned for storing dental care material prior to use. The well (16) may be of any suitable size or shape. Typically, the well (16) should have a size and depth adequate to establish a well capacity sufficient to hold a typical application of dental care material. For example, the well (16) may be of a size and shape to provide a well capacity of, for example, at least 0.25 milliliters (mL) to no more than 5.0 mL, although in many embodiments, the well (16) may provide a capacity outside of this range. In some embodiments, the well (16) may be of a size and shape to provide a well capacity of, for example, at least 0.25 mL, at least 0.5 mL, at least 1 mL, at least 2 mL, at least 5 mL, at least 10 mL, or greater. The well may have a capacity of, for example, no greater than 25 mL, no greater than 10 mL, no greater than 5 mL, no greater than 2 mL, no greater than 1 mL, or no greater than 0.5 mL. Also, devices intended for other applications, within or beyond the dental and/or health care-related arts, may include a capacity of, for example, at least 0.25 mL, at least 0.5 mL, at least 1 mL, at least 2 mL, at least 5 mL, at least 10 mL, or greater. The well may have a capacity of, for example, no greater than 25 mL, no greater than 10 mL, no greater than 5 mL, no greater than 2 mL, no greater than 1 mL, or no greater than 0.5 mL. Also, regardless of the particular application, the well (16) may be round, ovoid, rectangular, square or any other suitable shape.
The well (16) includes a bottom surface (18) that, in typical use, rests against a portion of the user's body such as, for example, a finger, a hand (particularly, but not exclusively, the back of the hand), a wrist, or an arm. As used herein, the term “finger” refers to any digit of the hand and, therefore, can include the thumb. Also as used herein, the terms “rests against” and “adhere to” a portion of the users body is not intended to mean, and should not be construed to require, direct contact between the bottom surface of the well and the user's body. The bottom surface of the well may rest against or adhere to a covering (e.g., a glove, gown, drape, or sleeve, etc.) that covers at least a portion of the user's body.
In some embodiments, shown in
In some embodiments, the well (16) may further include a cover film (26) adhered to at least a portion of the top surface (14) of the receptacle (12), as shown in
The cover film (26) may be made of any suitable material. In embodiments, in which, for example, material (e.g., dental care material) is stored in the well (16) and covered with a cover film (26), the cover film (26) should be compatible with the stored material—i.e., the cover film (26) material should not substantially degrade or compromise the effective use of the stored material over typical storage times. Suitable materials for the cover film (26) include, for example, aluminum, polypropylene, polyethylene, polyethylene terephthalate, and combinations thereof.
The cover film (26) and/or the top surface (14) of the receptacle (12) may include one or more features that permit the cover film (26) to be conveniently removed. For example, the cover film (26) may include a tab that overhangs and/or is not adhered to any portion of the top surface (14) of the receptacle (12). The cover film (26) tab may be grasped for convenient removal of the cover film (26). In other embodiments, the top surface (14) of the receptacle (12) may include a frangible section that may be broken to provide a tab that is readily grasped for removing the cover film (26).
In some embodiments, the receptacle can include a plurality of wells. Such embodiments may be useful, for example, for providing convenient access to a plurality of dental care materials that are to be simultaneous or sequentially administered to a patient. Alternatively, a plurality of wells may be useful for providing convenient access to a volume of, for example, dental care material that is greater than the capacity of a single well. In this way, various volumes of material can be provided without having to manufacture different sized wells. A plurality of wells also can permit storage of, for example, a dental care material in one well, which remains sealed during storage to reduce the likelihood and/or extent to which the dental care material is contaminated or otherwise compromised during storage. For use, the dental care material may be transferred to another well and, optionally, mixed with another material. Transferring the dental care material from the first well to a second well may include, for example, removing a cover film (26). Alternatively, dental care material may be transferred from one well to another via a selectively openable passage (42), describe in more detail below in connection with
The mounting portion (22) of the device (10) is generally constructed to fit, or may be reformed to fit, over and/or around a portion of the user's body. In certain embodiments, the device (10) may include a plurality of mounting portions (22) so that the device (10) can fit, for example, over a plurality of the user's fingers. In other configurations, a plurality of mounting portions (22) may be aligned so that more than one mounting portion (22) can fit over and/or around the same portion of the user's body. For example, two mounting portions may be aligned so that both mounting portions (22) can fit over and/or around a user's finger. The mounting portion (22) may assume various forms and, when a plurality of mounting portions (22) is present, the device (10) may include a plurality of mounting portion forms in any combination.
In some embodiment, as shown in
The mounting portion (22) may include a full ring (30), as shown in
In embodiments that include an at least partial ring (30), the device (10) may further includes a flexible connection (28) connecting the receptacle (12) and the mounting portion (22), as shown in, for example,
Typically, the at least partial ring (30) is generally co-planar with the top surface (14) of the receptacle (12) during storage. The flexible connection (28) permits repositioning of the mounting portion (22) with respect to the receptacle (12) so that the mounting portion (22) fits over and/or around a portion of the user's body and the receptacle (12) can rest on top of the a portion of the user's body. By bending the flexible connection (28), the mounting portion (22) may be repositioned to position at any suitable angle with respect to the receptacle (12) such as, for example, a position that is generally perpendicular to the top surface (14) of receptacle (12), although the mounting portion (22) may be repositioned at other angles if desired by the user. However, the flexible connection (28) need not necessarily precisely maintain its repositioned conformation. For example, in embodiments in which the flexible connection possesses spring memory (28), the flexible connection (28) may tend to return to its original position after being repositioned. The tendency to return to its original position may provide sufficient pressure against a part of the user's body to provide stability of the device (10) during use. Considerations such as, for example, sizing, stability, spring memory, and comfort may influence, at least in part, the particular angle at which the mounting portion (22) is repositioned with respect to the receptacle (12).
In some embodiments, the device (10) may include one flexible connection (28) between the receptacle (12) and a mounting portion (22), as shown in, for example,
In some embodiments, as shown in
In some embodiments, the device (10) can include a plurality of wells (16) and (16′), as shown in, for example,
Referring to
Features of the various embodiments described above may be combined with one or more features of other embodiments as appropriate. One such combination embodiment is shown, for example, in
Also, in embodiments that include a plurality of wells (16) and fewer mounting portions (22) than wells (e.g., two wells (16) and one mounting portion (22)), each mounting portion may be designed to be in close proximity to any well or, alternatively, located substantially equidistant from each of two wells. Thus, in embodiments such as that depicted in
In some embodiments, the mounting portion (22) includes at least two flexible mounting portions (34) in which each flexible mounting portion (34) includes a distal end (36). In such embodiments, the distal end (36) of at least one flexible mounting portion (34) includes a fastener system (38). The fastener system (38) may be used to fasten the distal ends (36) of the flexible mounting portions (34), thereby securing the device (10) around a portion of the user's body.
The fastener system (38) may include any suitable system that permits securing the device (10) to a portion of the user's body. Suitable fastener systems (38) include, for example, ties, slits, a tab and slot, adhesive, snap, button and button hole, hook and loop fasteners, and the like. In certain embodiments, the distal end (36) of only one flexible mounting portion (34) may require a fastener system (38) component (e.g., an adhesive). In other embodiments, the distal end (36) of a first flexible mounting portion (34) can include a first fastener system (38) component (e.g., slits, hook and loop, etc.) and the distal end (36) of a second flexible mounting portion (34) can include a second fastener system (38) component. Also, some fastener systems (38) may be well-suited for permitting variable sizing of the fastened mounting portions (22) (e.g., adhesive, hook and loop, etc.). Such embodiments may be able to be conveniently and comfortably used by wider variety of individuals possessing diverse dimensions of the portion of the user's body over and/or around which the device (10) should fit. In some embodiments, the fastener system (38) merely includes forming the flexible mounting portions (34) of a material that is shapable. As used herein, term “shapable” refers to a material that may be, for example, bent, flexed, or twisted to form a desired shape and, once shaped, will substantially hold its new shape until reshaped or for a period of time sufficient for typical use (e.g., at least three, ten, 30, 60 minutes).
In certain embodiments, the device (10) may be designed to so that the receptacle (12) is preferably positioned relative to each of the fastener system (38) component(s) used to fasten the device (10). For example,
In some embodiments, shown in
The applicator tray (112) and device (10) may be connected directly such as, for example, by a frangible connection (120). One such arrangement is shown in
Alternatively, the applicator tray (112) and the device (10) as described above may be connected indirectly such as, for example, each being adhered or affixed to a connecting material. The connecting material may include, for example, a cover film or a packaging component.
