Claims
- 1. A carrier comprising:
a central support structure having at least one support panel and a handle structure; a pair of foldable side wall structures each extending outwardly from one of said central support structure when unfolded to form a side wall for a retainer structure; each of said side wall structures comprising a plurality of panels attached together and to said support structure along vertical fold lines, each of said side wall panels having an upper edge and a lower edge, said side wall panels including one panel spaced from and opposing said central support structure; each of said central panel structure and said one side wall panel having a foldable flange structure extending outwardly from the lower edge thereof and overlapping the other flange to form a bottom support structure for said retainer structure when unfolded.
- 2. A carrier as in claim 1 including at least one foldable divider wall having two ends and extending between and secured to said central support structure at one of said ends, and to said one panel at the other of said ends.
- 3. A carrier as in claim 1 in which each of said side wall structures includes four walls, each having a flange extending from its bottom edge, each of said flanges being secured to an adjacent flange with a diagonal fold line to permit folding of said flanges, to provide support for said flanges to form a bottom for said retainer structure.
- 4. A carrier as in claim 1 in which said central support structure comprises a panel folded to form two panels with the fold line forming the upper edge of said central support structure, each of said retainer structures extending outwardly from one of said panels of said support structure.
- 5. A carrier as in claim 2 in which said divider wall has an upper edge and a lower edge, said lower edge being spaced upwardly from the lower edges of said side wall panels to permit downward unfolding of said flanges.
- 6. A carrier as in claim 2 in which each of said divider walls is formed as a hinged cut-out from one of said central support structure panels.
- 7. A carrier as in claim 1 in which at least one of said flanges has a lateral edge positioned to contact another surface to hold said side walls in the unfolded position and deter said carrier from returning to its folded position.
- 8. A carrier as in claim 7 in which said other surface is a lateral edge on the other of said flanges.
- 9. A carrier as in claim 8 in which each of said flanges has a projection which has said lateral edge so that when said flanges are unfolded said lateral edges engage one another to hold said side walls in the unfolded position.
- 10. A carrier comprising:
a plurality of separate carrier units coupled together to form a single carrier; each of said units comprising a vertical panel support structure with a pair of receptacles extending from adjacent the lower area of said support panel structure, said support panel structure having a handle hole adjacent the upper edge of said panel and extending relatively near at least one side edge of said panel; and a tray having a central slot long enough to embrace the panels of said units simultaneously, said tray being fitted over at least two of said support panels to join said units together with said handle holes close to one another so that both can be grasped by a person using one hand.
- 11. A carrier as in claim 10 in which each of said units has at least two receptacles, one on each side of said support panel, and each receptacle has a plurality of side-folding side wall panels forming a rectilinear enclosure, and a plurality of flanges at the bottoms of said side wall panels, said panels overlapping one another and selectively secured together to form a bottom wall for a receptacle when unfolded.
- 12. A carrier as in claim 10 in which each of said support panel structures comprises a single panel folded over to form two panels hinged together along the top edge of said support panel structure.
- 13. In a folding carrier for containers or food, said carrier having a carrying support structure with a handle and at least one folding receptacle secured to said support structure,
said receptacle having a foldable side wall structure having a plurality of side walls joined together along fold lines to form a foldable enclosure, each of said side walls having an upper edge and a lower edge and corners at said fold lines, and a bottom structure formed by foldable flanges extending from said lower edge of at least two adjacent ones of said side walls, said flanges being secured to one another adjacent one of said corners.
- 14. A carrier as in claim 13 including a diagonal fold line for at least one of said flanges adjacent said one corner.
- 15. A carrier as in claim 13 in which said foldable enclosure has a generally rectangular shape with four opposed corners, said bottom structure including two other flanges extending from others of said side walls and secured together at a corner opposite said one corner.
- 16. A carrier as in claim 13 at least one of said flanges at each of said corners having a diagonal fold line extending outwardly from the corner.
- 17. A carrier as in claim 14 said flanges being secured together only on one side of said diagonal fold line.
- 18. A carrier as in claim 13 in which each of said flanges has two opposite ends, one of said ends of one of said flanges being secured to the other of said flanges, and the opposite end of said one flange being cut off at an angle.
- 19. A carrier as in claim 13 in which said enclosure has a length and a width, and one of said flanges extends for substantially the entire width of said enclosure.
- 20. A carrier as in claim 19 in which said one flange has a far edge which frictionally engages an opposed one of said side walls when said side walls are unfolded, thereby to held said one flange in place and form a first layer of a multi-layer bottom wall resting on at least one other flange.
- 21. A carrier as in claim 20 including two other flanges secured together adjacent a corner of said enclosure opposite to the first-named corner.
- 22. A carrier as in claim 13 including a least one divider secured at one end to one of said side walls, and at the other end to said support structure.
- 23. A folding carrier for containers or food, said carrier having a central support structure with a pair of opposed receptacles extending from opposite sides of said central support structure, each of said receptacles having:
a foldable side wall structure having a plurality of side walls joined together along fold lines to form a foldable enclosure, each of said side walls having an upper edge and a lower edge and corners at said fold lines; a bottom structure formed by foldable flanges extending from said lower edge of at least two adjacent ones of said side walls, said flanges being secured to one another adjacent one of said corners; including a diagonal fold line for at least one of said flanges adjacent said one corner; and in which said foldable enclosure has a generally rectangular shape with four opposed corners, said bottom structure including two other flanges extending from others of said side walls and secured together at a corner opposite said one corner.
- 24. A carrier as in claim 23 in which said enclosure has a length and a width, and one of said flanges extends for substantially the entire width of said enclosure.
- 25. A carrier as in claim 24 in which said one flange has a far edge which frictionally engages an opposed one of said side walls when said side walls are unfolded, thereby to hold said one flange in place and form a first layer of a multi-layer bottom wall resting on at least one other flange.
- 26. A carrier as in claim 25 including slots in said opposed side wall and projections from said far edge to fit into said slots to hold said one flange down.
- 27. In a folding carrier for containers or food, said carrier having a carrying support structure with a handle and at least one folding receptacle secured to said support structure,
said receptacle having a foldable side wall structure having a plurality of side walls joined together along fold lines to form a foldable enclosure, each of said side walls having an upper edge and a lower edge and corners at said fold lines, and a bottom structure formed by foldable flanges extending from said lower edge said flanges being shaped so as not to interfere with one another during unfolding of said receptacle and overlie one another, at least partially, so as to form a multi-ply bottom for said receptacle, adjacent ones of said flanges being attached to one another and having fold lines to allow said flanges to fold up but form reinforced bottom corners for the bottom of said receptacle when unfolded.
- 28. A carrier as in claim 27 including means for holding said flanges against folding up again after being unfolded.
