Abstract
Abstract A combination container and utility tray in which a tray is supported in and secured to an outer container. The interrelationship of the tray and the container together with the design of the tray is such as to permit the tray to be thermally formed of otherwise unacceptably thin sheet material thus saving in amount of materials used with resulting reduction in manufacturing costs while still providing a convenient and firm support for shipping and use of articles. The firmness of support is achieved by forming around the periphery of the tray a downwardly extending flange and forming in the main body of the tray a plurality of depressions for holding different objects with some of the depressions having a depth such that the bottom of the depression is in the same plane as the edge of the downwardly extending flange. The tray is held in a cardboard container having a bottom and sides, the cardboard container being only slightly larger than the tray so that the downwardly extending flange of the tray contacts the sides of the container with the bottom of the deeper depressions resting on the bottom of the container and being secured thereto. The tray, which is designed for storing and holding articles used in tooth treatment including stacked mixing trays and fluid containing vials, is formed with specially designed depressions for these articles. The depressions for the stacked mixing trays have an access through the side of the tray with their bottoms being secured to the bottom of the container. The depressions for the vials are in the form of wells each having a shallow portion, which fits the outer contour of the vial when in a prone position and a deeper portion which fits the contour of the base of thevial and is adapted to support the vial in an upright position.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
269 words
A combination container and utility tray comprising an outer container having sides and a bottom, a tray formed of relatively thin flexible material supported by said container and secured thereto said tray having a downwardly extending flange around the periphery thereof the width of said flange being greater than the width of the sides of said container and said downwardly extending flange contacting the sides of said container, said tray having a plurality of depressed areas formed therein for holding articles to be used, at least one of said depressed areas being positioned near one side of said tray and having an access thereto through said downwardly extending flange the bottom of said depressed area being on the same plane as the edge of said flange and the bottom of said depressed area being secured to the bottom of said container, and at least one of said depressed areas being in the form of a well designed for holding a vial having an upper portion and a lower portion with said well having a shallow portion and a deep portion the shallow portion of said well having substantially the same configuration as that of the upper portion of said vial and the deep portion of said well having substantially the same configuration as that of the lower portion of said vial whereby the vial may be supported in a prone position in the shallow portion of said well and in an upright position in the deep portion of said well and raised from its prone position to its upright position by pressure on the lower portion of said vial.
Claim 2
Dependent Claim
269 words
A combination container and utility tray comprising an outer container having sides and a bottom, a tray formed of relatively thin flexible material supported by said container and secured thereto said tray having a downwardly extending flange around the periphery thereof the width of said flange being greater than the width of the sides of said container and said downwardly extending flange contacting the sides of said container, said tray having a plurality of depressed areas formed therein for holding articles to be used, at least one of said depressed areas being positioned near one side of said tray and having an access thereto through said downwardly extending flange the bottom of said depressed area being on the same plane as the edge of said flange and the bottom of said depressed area being secured to the bottom of said container, and at least one of said depressed areas being in the form of a well designed for holding a vial having an upper portion and a lower portion with said well having a shallow portion and a deep portion the shallow portion of said well having substantially the same configuration as that of the upper portion of said vial and the deep portion of said well having substantially the same configuration as that of the lower portion of said vial whereby the vial may be supported in a prone position in the shallow portion of said well and in an upright position in the deep portion of said well and raised from its prone position to its upright position by pressure on the lower portion of said vial.
Claim 3
Dependent Claim
34 words
A container and utility tray of claim 1 in which some of said depressed areas are designed for holding articles other than vials and have a depth less than the width of said flange.
Claim 4
Dependent Claim
49 words
A container and utility tray of claim 1 in which at least one of said depressed areas has a depth equal to the width of said flange and has no access through the side of said tray said depressed area having three substantially perpendicular sides and one sloping side.
Claim 5
Dependent Claim
34 words
A container and utility tray of claim 3 in which the sloping side of said depressed area slopes upwardly towards the side of said tray which contains the access through the downwardly extending flange.
Claim 6
Dependent Claim
266 words
In a utility tray formed of relatively thin flexible material and having front and rear portions a downwardly extending peripheral flange, supporting depression adapted to contain articles and help support said tray the bottoms of said supporting depressions being on the same plane as the edge of said flange with the bottoms of said supporting depressions and the edge of said peripheral flange adapted to rest on any flat surface on which said tray may be placed, at least one of said supporting depressions being positioned in the front portion of said tray with access thereto through said flange, another of said supporting depressions being more centrally located with respect to said flange and having no access therethrough said other of said supporting depressions having three substantially perpendicular sides and one sloping side with the sloping side sloping towards the side of said tray for easy removal of items therefrom, and a plurality of wells adapted to hold vials each well having a shallow portion and a deep portion the shallow portions of said wells having substantially the same configuration as that of the upper portion of a vial to be contained therein and the deep portion of said well having substantially the same configuration as that of the lower portion of said vial to be contained therein whereby the vial may be supported in a prone position in the shallow portion of said well and in an upright position in the deep portion of said well and raised from its prone position to its upright position by pressure on the lower portion of said vial.
