Abstract

Carton construction comprising an outer sleeve member and at least one inner tray member adapted to be inserted within the outer sleeve member to provide an assembled container and closure. Each of the inner and outer members being formed from separate blanks of pasteboard or like material provided with a finished and/or printed surface on one side of each of the blanks and an unfinished surface on the opposite side of the blanks. Each of the inner and outer members in the respective assembled condition thereof having no exposed or visible raw edges along the exterior thereof.

Claims

1. A tray member suitable for containing articles therein in combination with an outer sleeve member into which said tray member is adapted to be inserted, said tray member comprising a bottom panel having pairs of opposite side edges and opposite end edges, an outer side wall panel extending upwardly from said bottom panel and integral therewith along each of said side edges, an outer end wall panel extending upwardly from said bottom panel and integral therewith along each of said end edges, each of said outer side wall panels having an upper edge and opposite end edges, each of said outer end wall panels having an upper edge and opposite side edges, each of said outer side wall panels further having an inner side wall panel integral therewith along said upper edge thereof and opposite end flaps integral therewith along said opposite end edges thereof, each of said outer end wall panels further having an inner end wall panel integral therewith along said upper edge thereof and opposite side flaps integral therewith along said opposite side edges thereof, said end flaps of each of said outer side wall panels being formed as an independent and separate piece apart from an adjacent side flap on said inner end wall panels, one of each adjacent end flap and side flap being folded 180°

along the edge along which it is integral with an outer side or end wall panel and secured to an inner surface of said outer side or end wall panel, the other of each adjacent end flap and side flap being folded 90°

along the edge along which it is integral with an outer side or end wall panel and secured to said adjacent flap along confronting surfaces thereof, said inner side and end wall panels each being folded inwardly 180°

along the upper edges of the outer side and end wall panels, respectively, whereby said tray in its assembled condition has no exposed or visible raw edge along the exterior thereof, said outer sleeve member comprising a plurality of wall panel portions and of which each panel portion is formed of at least two-ply thickness with all exposed or externally visible edges thereof being folded and thereby showing no raw cut edges, said combination with said tray member inserted in said outer sleeve member may be adaptable to being placed on a shelf in a position on an end with the bottom panel of said tray extending vertically, said outer sleeve member in the storage condition of said combination including a generally elongated opening which may be directed toward the back of a book shelf and a generally elongated wall section opposite to said opening, and said wall section being finished along its exterior surface as a facsimile portion of a book cover.

2. The tray member of claim 1 in combination with a cover member adapted to be placed over said tray in telescoped fashion, said cover being identical in construction to that of said tray, but of slightly greater dimension.

3. The combination of claim 1 wherein prior to inserting said tray member into said outer sleeve member for storage said tray member is inserted in telescoped fashion into a cover member, said cover member being identical in construction to that of said tray, but of slightly greater dimension.

4. A blank for forming a container sleeve member comprising a bottom liner surface on which is provided a first main panel, a second main panel integral with said first main panel along a first edge, a third main panel integral with said second main panel along a second edge, an assembly flap integral with said third main panel along a third edge, a fourth main panel integral with said first main panel along a fourth edge on the side opposite to said second main panel, a reinforcement panel integral with said fourth main panel along a fifth edge or fold line, all of said edges being generally parallel to each other, said blank further including auxiliary panels extending from lower edges of said first, second and third main panels, a fifth main panel integral with and extending along an upper edge of said first main panel, an auxiliary panel extending along the upper edge of said third main panel, a reinforcement panel extending along the upper edge of said fifth main panel, said fifth main panel having trapezoidal end flaps extending from opposite ends thereof, said reinforcement panel having trapezoidal cutouts at opposite ends thereof in which said end flaps may be received, foldable flaps extending along upper edges of said second and fourth main panels and formed by cutting at least along two sides of said trapezoidal end flaps, and a foldable flap extending from the lower end of said fourth main panel.

5. The blank as defined in claim 4 wherein notches are formed along sides of said first and third main panels and said auxiliary panels extending from said first and third main panels.

6. The blank as defined in claim 5 wherein said foldable flap extending from the lower end of said fourth main panel and said reinforcement panel integral with said fourth main panel each include edge portions formed along a common line whereby said edge portions will be complementary to each other when folded along side each other in a commmon plane.

7. A container sleeve member comprising five main panels, each of which is reinforced by at least a second layer of material folded and lapped over each of said five main panels to provide at least a double thickness of material, each of said five main panels being generally rectangular in shape and including portions folded along each edge of each of said panels so that raw edges will not be visible along the exterior thereof, one of said main panels including a first extension along one edge thereof and a second extension along a second edge adjacent to said first edge, said first and second extension including portions formed along a common line with said portions extending alongside each other in complementary angle portions against said one of said main panels in the assembled condition of said sleeve.

8. The sleeve member as defined in claim 7 wherein a second one of said main panels is provided with folded extensions on opposite ends thereof and an additional folded extension on an additional side thereof, said additional folded extension being provided with cutouts on opposite ends thereof complementary to said folded extensions on opposite ends of said second one of said main panels whereby in the assembled condition said extensions of said second one of said main panels are folded thereagainst without overlap between either of said end extensions and said additional folded extension.
