1. Field of the Invention
Orthodontic brackets are small metal appliances that are adhered to the surface of a tooth. Frequently, such brackets are sold as a set. There is a unique bracket shape and design for each tooth. Some brackets have features, such as tie wings, not possesses by others. Some types of brackets have moving parts. Examples of various types of bracket design are shown in Hagelganz et al., U.S. Pat. No. 7,878,802, and in Hagelganz, published application US2011/0039225.
Brackets are tiny metal pieces and as such are easy to lose. Further, many bracket types are similar and if the parts of a set become jumbled together, it may be inconvenient to separate and positively identify each type according to its function.
Traditionally brackets have been packaged for sale in trays having square cut-out wells covered by a plastic transparent cover that either slides over the wells or snaps into place. However, the wells are a single size and shape, which means that the larger items may fit, but not snugly, and the smaller items rattle freely and may fall out.

None.
A package for a set of orthodontic appliances includes a tray having a plurality of open pockets in which each pocket is sized and shaped to receive a selected orthodontic bracket according to its shape and dimensions such that each bracket is held snugly therein. The tray includes a tab at one end adapted to be grasped between a user's thumb and forefinger, and a cover is provided which is adapted for slideable engagement with the tray for covering the open pockets.
The foregoing and other objectives, features, and advantages of the invention will be more readily understood upon consideration of the following detailed description of the invention, taken in conjunction with the accompanying drawings.
According one embodiment, a package for a set of orthodontic brackets is provided which includes a tray and a cover. The tray contains sized and shaped pockets for a full set of orthodontic brackets. Each pocket is uniquely sized and shaped to fit a particular bracket type in a set, which includes a bracket for each tooth. A slideable cover contains the brackets within the pockets and may be transparent so that the user can see the entire set within. The set is arranged so that the pockets and associated brackets correspond to the exact order of a set of human teeth; that is, the brackets for the molars are at the ends of the package and brackets for the premolars, cuspids and incisors are placed in order toward the middle of the tray. The packaging of brackets in this way provides protection from counterfeiting of bracket sets because the package uniquely fits only brackets manufactured to exact tolerances and shapes. Thus, cheap imitation goods cannot fit in packaging designed only for manufacturers brackets made to specifications and thus cannot be passed off as genuine. Further by its position in the package the orthodontist knows exactly which tooth the bracket fits.
In addition, the trays are compact and stackable, which makes them especially useful in vending machines. Vending machines are used in orthodontic clinics as a means of inventory control, but such use requires careful packaging of the product. The low rectangular profile of the package lends itself to easy loading and manipulation in machines designed to eject small regularly shaped objects.
A tab or thumb pad at an end of the package permits it to be pulled out of a stack without causing the cover to slide off. This is accomplished by having a boss at the same end of the tray as the thumb pad. The boss locks to the cover by engaging a notch. Further, the covers have side bottom flanges, which are directed inwardly. These flanges have inner surfaces that are in sliding engagement with shaved or beveled bottom side edges on the trays.
Referring now to the drawings, a package 10 has two parts, a cover 12 and a tray 14. The tray 14 has a set of pockets 16. As shown best in
The cover 12 has a top 13, which is transparent, and sides 20 and 22 which fit the outer dimensions of the tray. The cover 12 slides onto the tray and the top 13 covers the pockets preventing the brackets, such as brackets 18, from dropping out of their pockets. The cover 12 is held in place by a boss 24 on the tray, which fits into a notch 26 in the cover 12. Also as shown best in
For ease of manipulation by a user, a thumb pad 35 is provided so that the package may be carried between thumb and forefinger. Depending upon the design of the vending machine holding the packages the thumb pad 35 may also be used to extract the package from the machine. The boss 24 is at the same end of the tray 14 as the thumb pad so that one may hold the thumb pad and pull back on the cover sliding it back to expose the pockets.
The terms and expressions that have been employed in the foregoing specification are used therein as terms of description and not of limitation, and there is no intention, in the use of such terms and expressions, of excluding equivalents of the features shown and described or portions thereof, it being recognized that the scope of the invention is defined and limited only by the claims which follow.
