DETAILED DESCRIPTION OF THE DISCLOSURE

[0017] The present disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the disclosure are shown. This disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

[0018] A package according to the present invention is shown by way of example by the number 10 on the attached drawings. Package 10 includes a base 11 and a plurality of wells or pockets 12 in base 11. As shown in FIG. 1, there are preferably two rows of pockets 12, row 20 and row 21, corresponding in turn to the upper and lower arch of a patient (not shown). Row 20 and 21 may be spaced apart by a top portion 22 of base 11. Top portion 22 may be used for example to carry indicia (not shown) corresponding to a treatment procedure.

[0019] It will be appreciated that a series of brackets such as bracket 30 (FIG. 3) can be individually placed in pockets 12 in a prescribed sequence, such as that corresponding to a patient's dentition, the order of use or the like.

[0020] Each pocket 12 is provided with an inclined floor 40. By inclined it is meant that floor 40 is tilted with respect to top portion 22 or the like. By such an inclined positioning, a bracket 30 placed within a pocket 12 will be induced by gravity toward the lower end of the inclined floor, depicted by the number 41 on the drawings. A back wall 42 is preferably provided to at least partially surround the lower end 41 of the pocket 12, thereby further holding the bracket 30 therein.

[0021] It is also preferred to provide each pocket 12 with a mechanical holding means or device to physically engage the bracket 30 in the pocket 12, thereby further securing the bracket 30 in the pocket 12. By mechanical holding means or device it is meant a structure that holds the bracket, preferably in a removable manner, by physical contact, without the need for an adhesive. By way of example, pins 51 may be provided in pocket 12 such that separate pins 51 are in a spaced arrangement such that the bracket 30 may be placed between them. By preferably being spaced apart a distance slightly less than that of bracket 30, pins 51 physically engage and hold bracket 30 there between by friction or by resilient force. By forming pins 51 from a suitable material such as a plastic, elastomer or the like, pins 51 may slightly deform as bracket 30 is placed there between and then exert a resilient force toward each other, impinging upon and holding bracket 30 in place.

[0022] As shown in FIG. 2, a suitable cover or lid 52 may be provided to enclose base 11 and cover each pocket 12 until desired use. When it is desired to use a given bracket 30, cover 52 is removed and a bracket 30 is removed from a pocket 12 by use of a tweezers or other tool. By being open and having inclined floor 40, such removal is facilitated.

[0023] Package 10 and its components as described above may be formed by any suitable means and from any suitable material. Preferably package 10 is formed from a plastic, elastomeric or other polymeric material by injection molding, vacuum or other thermo-forming, milling or any other conventional method.

[0024] As shown in FIGS. 4 and 6, an alternative embodiment of a package according to the invention is shown by the number 10, and includes a base 60 and a single well or pocket 61. Pocket 61 has an inclined floor 62 similar to floor 40 above described. In this embodiment, pocket 61 is elongate in shape and provided with a floor covering 70 having a plurality of individual and preferably regularly spaced bracket receiving apertures 71. Each aperture 71 is sized and configured to receive a bracket 30 and physically engage or touch bracket 30 to hold bracket 30 therein. Preferably floor covering 70 is made of a resilient material such as a foam rubber, polystyrene, polyurethane, paper, plastic or any other resilient material. Each aperture 71 is preferably sized and shaped to have at least one dimension that is slightly less than the outer dimension of at least a portion of a bracket 30 to be held therein, such that aperture 71 physically impinges upon or touches bracket 30 to hold bracket 30 therein. By being preferably formed from a resilient material, floor covering 70 and hence, apertures 71 can thus be slightly deformed when a bracket 30 is placed within an aperture 71, and then resiliently physically impinge upon bracket 30, securing it in place within aperture 71 until intentionally removed by a user. Such a configuration is an example of a mechanical locking device according to the present invention.

[0025] As with rows 20 and 21 of base 11 described above, base 60 may be provided with well 61 and a second well 62, each corresponding to an upper or lower arch of a patient. A flat area 63 may be provided to include indicia (not shown) as was similarly above described with respect to flat area 22. Further, although base 60 and floor covering 70 are shown and described as being separate materials, the structure could in fact be of a singular, monolithic manufacture, that is, made as a single piece and still have the characteristics as above described. It will additionally be appreciated that the shape, size and distribution of pockets 12, wells 61, 62 and apertures 71 may vary depending upon the desired end use and still fall within the scope of the present invention.

[0026] Each aperture 71 may also be provided with one or more cutouts 80. It will be appreciated that when it is desired to remove a bracket 30 from an aperture 71 wherein it is held, a tweezers or other tool (not shown) may be positioned in one or more cutouts 80 to engage and lift, pry or otherwise remove bracket 30 from the given aperture 71. The package 10 may be provided with a lid 81 similar to lid 52 above described.

[0027] It is often encountered in the orthodontic market that a bracket 30 is packaged and shipped to the end user with a bonding adhesive affixed to the bracket 30, which adhesive will be used to bond to the patient's tooth (not shown). In this circumstance, package 10, 10 and its associated lid 52, 81 may be made from an opaque material to restrict the transmission of light including UV light. This helps to prevent premature curing of the bonding material affixed to the bracket, especially when such material is cured by exposure to light. UV-cured bonding materials are common in the industry. In addition, a shield of material similar to lid 52, 81 could be provided that blocks the light that will cure the pre-pasted bonding material, but that allows the transmission of other light so that a user would still be able to view the contents of the package 10, 10. For example, the lid or shield 52, 81 could be made of a material that blocks UV light but allows visible light to be transmitted through to allow such viewing. Although lids 52, 81 are depicted in the drawings as closure lids for packaging 10, 10, the UV shield could just as well be a separate piece of material of any configuration placed within the package 10, 10.

[0028] In a still further embodiment of the package 10, floor covering 70 may be provided with an undercut 90 positioned generally juxtaposed to aperture 71. In FIG. 9, cutout 90 is shown as having top and bottom walls 91 and 92 respectively, and sidewalls 93 and 94 respectively. Although shown as being square, cutout 90 need not be of any particular shape as long as it meets the characteristics to now be described.

[0029] Cutout 90 is particularly suited for use with a bracket 30 having a base member 100 (FIG. 8) that is pre-pasted. By positioning bracket 30 having base member 100 in aperture 71 with cutout 90, bracket 30 is held in aperture 71 but the base member 100 is held at its edges only (FIG. 10). The pre-pasted bonding material (not shown) on base 100 would not be touched by a surface of package 10, thereby maintaining the integrity of the bonding material during storage of bracket 30 within package 10.

[0030] While only certain features and embodiments of the invention have been shown and described, many modifications and changes may occur to those skilled in the art (for example, variations in sizes, dimensions, structures, shapes and proportions of the various elements, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter recited in the claims. The order or sequence of any process or method steps may be varied or re-sequenced according to alternative embodiments. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention. Furthermore, in an effort to provide a concise description of the exemplary embodiments, all features of an actual implementation may not have been described (i.e., those unrelated to the presently contemplated best mode of carrying out the invention, or those unrelated to enabling the claimed invention). It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation specific decisions may be made. Such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure, without undue experimentation.
