The present invention relates to a disposable applicator for applying different materials, and in particular to a disposable dental applicator having multiple tools used to apply dental materials.
Applicators such as brushes, foam pads, cotton fiber or other applicators, are used to apply a variety of materials in many applications. Such applicators are of particular use in dentistry for applying various dental materials. as many dental procedures require various dental materials, such as sealants, bonding agents and the like, to be painted onto a tooth in thin, even coatings or layers. Also, it invariably happens that after several uses, the dental materials would tend to accumulate onto reusable dental applicators resulting in a time-consuming cleaning problem. Moreover, because of the need for sterilization to prevent cross-contamination between patients, the use of multiple applicators requiring frequent cleaning have been used. Because the dental materials in current use include various materials that cure in a relatively short period, cleaning and/or sterilization of such dental devices proves difficult, costly and in some cases unsafe. With the advent of contagious and dangerous communicable diseases and the quick setting dental materials tools that can be readily disposed of are beneficial to dental procedures. In view of the above listed shortcomings, a disposable multi-functioning, interchangeable, multi-tooled applicator is desirable. As a result, it is necessary to produce a double-ended multiple-tooled dental applicator apparatus that is efficient and easy to handle at a low cost.
The present invention addresses the above-described deficiencies and others as described further below. Specifically, the present invention provides a dual-ended disposable multi-tool dental applicator apparatus with interchangeable tools that is disposable.
In accordance with an aspect of the present disclosure, the instant invention provides a low cost, easy to manufacture, disposable dental tool comprised of lightweight but sufficiently rigid, readily available material such as plastic.
The instant invention advantageously allows for the ability of at least three dental applicator tools all within a dual sided body having detachably interchangeable tools providing enhanced versatility and faster procedures.
In accordance with an aspect of the present disclosure, the instant invention provides a double ended, inexpensive, easily disposable device providing various tools that facilitate multiple functions within a unitary apparatus.
In accordance with another aspect of the present disclosure, the instant invention provides a multiple function applicator apparatus with enhanced gripping means for facilitating increased safety, speed and efficiency with performing dental procedures.
In accordance with another aspect of the present disclosure, the instant apparatus is a lightweight uncomplicated structure comprised of a dual sided, double tooled applicator apparatus with interchangeable tools that is easily discarded after use and is made of readily available materials allowing for easy and low cost manufacture.

Combinations of components or steps will also be considered as being noted, where terminology is foreseen as rendering the ability to separate or combine is unclear.
The DATR 100 comprises a cylindrical handle 105 having a proximal end 122 and a distal end 152 with a first dental application tool 120 at the proximal end, and tool receptacle 150 at the distal end 152. The handle 110 of the DATR 100 is substantially cylindrical and extends along a longitudinal axis and has a central axis along its length, and a width of approximately a quarter inch thick.
In this embodiment, the first dental application tool 120 is a spatula, however it is within the purview of one skilled in the art to recognize that the first dental application tool 120 can be any number of dental applicators such as for example any array of micro-brushes, long or short tipped applicators, and/or frangible tools, for providing ways of dispensing and distributing solutions, sealants, composites, and bonding materials during dental procedures.
In the embodiment shown in the figures, the first dental application tool 120 comprises a spatula having a wedged tool body 121 that is offset from the central axis of the cylindrical handle 105 at an offset angle ø of approximately 130 degrees, (plus or minus 5 degrees). The wedged tool body 121 of the spatula may have flat surfaces on both sides (as best seen in
On the opposite end of the DATR 100 at the distal end 152 is a tool receptacle 150 dimensioned and configured with recessed, interior circumferential beveled edges 153, a circumferential flange 154 and abutment 155 for receiving either of the set of tools on the proximal and distal ends of the DSDTA 200 (as can be best gleaned in the cross sectional
The DSDTA 200 comprises a cylindrical handle 205 having a proximal end 222 and a distal end 232, with dental tools on both ends, as shown in
As conceptually illustrated in
Conversely and alternatively, when the first dental applicator tool 220 of the DSDTA 200 is to be used, it is simply removed from the tool receptacle 150, and the cylindrical handle 205 is flipped such that the second dental applicator tool 230 of the DSDTA 200 may then be inserted within the tool receptacle 150 such that the dual-ended disposable multi-tool dental applicator apparatus with interchangeable tools 1000 may be handled by the user to employ both the use of the first dental applicator tool 220 of the DSDTA 200, along with the first dental applicator tool 120 of the DATR 100.
Upon completion of a given procedure, the dual-ended disposable multi-tool dental applicator apparatus with interchangeable tools 1000 is rendered readily disposable. In a preferred embodiment, the dual-ended disposable multi-tool dental applicator apparatus with interchangeable tools 1000 has a length of approximately 6-7 inches extending from the DATR's 100 most proximal end at 122 to the DSDTA's 200 most distal end 232.
To facilitate gripping and handling during dental procedures, the dual-ended disposable multi-tool dental applicator apparatus with interchangeable tools 1000 has three sets of frictional enhancement means. This is a great convenience to the user or dentist working in a wet environment with saliva, blood, detritus, and other debris culminating from the procedure. A first set of frictional enhancement means is on both ends of the DSDTA 200 and abuts both the first dental applicator tool 220 and the second dental applicator tool 230 at the proximal end 222 of the cylindrical handle 205, as well as the distal end 232 and comprises an array of a plurality of circumferential grooves or ridges 225 and 235, respectively.
The second set of frictional enhancement means extend longitudinally along both the DATR 100 and the DSDTA 200. Along the DATR 100 is a set of elongated grooves 110 along the entire length of the body of the cylindrical handle 105. Along the DSDTA 200 is another set of elongated grooves 210 which extend along the entire length of the cylindrical handle 205. The elongated grooves 110 and 210 are a set of repeating cored indentations each having approximate dimensions of about 0.07 inches in depth, 0.9 inches wide and 0.4 inches long in a preferred embodiment.
The third set of frictional enhancement means spiral about the entire length of both cylindrical handles 105 and 205 of the DATR 100 and DSDTA 200 respectively, and comprise a set of spiral grooves 115 and 215 having an approximate dimension of 0.03 inches deep, spiraling at an angle of 0.23 degrees relative to the central axis of cylindrical handles 105 and 205, and extend about the entire length thereof from the proximal and distal ends of both the DATR 100 and DSDTA 200.
On the DSDTA 200, the pair of plurality of circumferential grooves 225 and 235 are perpendicular to the elongated grooves 210, and the set of spiral grooves 215 extend diagonally relative to the elongated groves 210, and in some instances may intersect thereof. The intricacies of the frictional enhancement means further facilitates ease in turning and rotating the dual-ended disposable multi-tool dental applicator apparatus with interchangeable tools 1000 about the work environment as well as inverting the tool about opposite ends depending on which of the three tools the dentist or user needs during the procedure.
Moreover, both ends of the DSDTA 200 have dental applicator tools with tapered or beveled portions that contribute to gripping/friction. The first dental applicator tool 220 has a tapered portion 223 with a reducing diameter, which further facilitates gripping and manipulation while using the condenser during a procedure. This tapered portion 223 also facilitates fine motor movement of the fingers by the dentist or user for condensing bonding materials and the like during procedures and helps to improve visibility when working in small spaces, such as between or within teeth. This first dental applicator tool, which may be a ball burnisher condenser tool 221, is formed as a spherical ball in the preferred embodiment, however it may take the other geometric shapes.
The second dental applicator tool 230 on the opposite end of the DSDTTA 200 has a tapered portion 223 with a reducing diameter, which further facilitates gripping and manipulation while using the condenser during a procedure. This second dental applicator tool 230, which may be a micro-dental brush 231 in the preferred embodiment and is used in applying materials to a surface, may also have a tapered portion 233 that also facilitates fine motor movement of the fingers by the dentist or user for condensing bonding materials and the like during procedures and helps to improve visibility when working in small spaces, such as between or within teeth.
The dual-ended disposable multi-tool dental applicator apparatus with interchangeable tools 1000 having double and triple tools on either end of the apparatus always provides at least two dental applicator tools for use at any one time during procedures. Thus the dual-ended applicator permits the dentist to quickly rotate the apparatus along the procedure, greatly reducing the time needed to apply the various materials, which enhances efficacy. Accordingly, the dentist can alternately apply two or more different materials to a single patient quickly and easily with minimum waste of time and materials, greatly reducing cost to the patient.
The dual-ended disposable multi-tool dental applicator apparatus with interchangeable tools 1000 may be molded of a hard durable and rigid, and substantially rigid, solid plastic material. For example, it may be comprised of a suitable medical grade plastic having sufficient strength and rigidity, such as a Shore D rigid and hard plastic of a sufficient durometer to withstand the normal, tensile, tangential and other forces used when handling the apparatus during procedure. Although the dual-ended disposable multi-tool dental applicator apparatus with interchangeable tools 1000 is a disposable device, it may also be comprised of plastic materials that can be sterilized in an autoclave in the event that multiple uses are warranted.
Each of the distinct parts of the dual-ended disposable multi-tool dental applicator apparatus with interchangeable tools 1000, including the first dental applicator tool 120 of the DATR 100, the first and second dental applicator tools 220 and 230 of the DSDTA 200, as well as the handles 105 and 205 may have colors that is distinct from one another. For example, handle 105 may be black, and the handle 205 may be red, and the corresponding dental applicator tools 120, 220 and 230 could be white, green and yellow, as examples. However, any combination of distinct colors may be used. This is so that a user, such as a dentist, can easily distinguish either end. This is advantageous when different materials are being used for each applicator end. Moreover, in alternate embodiments, the dental applicator tools 220 and 230 may also contain one or more frangibly attached dental tool applicators extending from either or both of said first and second dental applicator tools 221 and 231, which may also be comprised of varying colors.
Accordingly, it should be appreciated that the present invention, in providing a relatively inexpensive, disposable applicator handle having an integrally formed, removable and interchangeable applicators on either end greatly reduces cost and waste; and, additionally, provides the user with flexibility in using a double ended applicator with either two or two or three independent and separate applicator tools.
The foregoing description of illustrated embodiments of the present invention, including what is described in the Abstract, is not intended to be exhaustive or to limit the invention to the precise forms disclosed herein. While specific embodiments of, and examples for, the invention are described herein for illustrative purposes only, various equivalent modifications are possible within the spirit and scope of the present invention, as those skilled in the relevant art will recognize and appreciate. For example, it should be appreciated that other geometric shapes of the handle portions, such as for example, hexagonal, may be used to form the shapes of the handles 105 and 205. Moreover, the first and second dental applicator tools 220 and 230 of the DSDTA 200 and the first dental applicator tool 120 of the DATR 100 may be formed of other shapes, such as for example an ovoid shape.
As indicated, these modifications may be made to the present invention in light of the foregoing description of illustrated embodiments of the present invention and are to be included within the spirit and scope of the present invention.
