Carrier and method
A foldable carrier is provided with a vertical support panel structure made as a first component, and an external side wall structure as a second component. The vertical support panel structure and the external side wall structure are joined together to form two separate receptacles extending from opposite sides of said vertical panel structure to hold objects to be carried in the carrier. Preferably, the vertical support panel structure is made of an untreated and relatively inexpensive material, and the external side wall structure is made of a material treated to give it good resistance to weakening when wet.
1. A foldable carrier, said carrier comprising
(a) a first component comprising an external side wall structure, said external side wall structure comprising
(1) a pair of long side panels, each having first and second ends;
(2) a first pair of shorter side panels, equal to one another in length, interconnecting one end of each of said long side panels together along fold lines; and
(3) a second pair of shorter panels, each being of the same length as said first shorter panels and being connected to one of said ends of said long side panels opposite the end connected to one of said first pair of shorter side panels,
(4) each of said side panels having a lower edge and a bottom-forming flange connected to said lower edge along a fold line, and
(b) a second component separate from said first component and comprising an internal support structure, said internal structure comprising:
(1) a pair of central support panels, each having a top edge, a bottom edge and two side edges; and
(2) each of said central support panels having a bottom-forming flange connected to said bottom edge along a fold line;
(c) said internal support structure being secured to said external side wall structure, and in which each of said flanges extending from said lower edges of said shorter side wall panels is foldable diagonally and is secured to an adjacent one of said flanges extending downwardly from one of said long side wall panels and one of said central support panels.
2. A carrier as in claim 1 in which said first component and said second component are made of materials selected from the group consisting of materials having the same wet-strength characteristics and materials having different wet-strength characteristics.
3. A carrier as in claim 2 including a handle structure secured to said top edges of said central support panels, and including a pair of side flanges, each extending from the outermost side edge of one of said second pair of shorter panels, said side flanges being secured together and to said handle structure, and to said central support panels.
4. A foldable carrier, said carrier comprising
(a) an external side wall structure, said side wall structure comprising
(1) two external side wall panel constructions, each comprising a long side wall panel with two opposed ends and a pair of shorter side wall panels each having a first side edge attached to one of said opposed ends along a fold line,
(2) each of said shorter panels having a second side edge opposite said first side edge,
(b) an internal wall structure, separate from said external wall structure, said internal structure comprising
(1) a pair of central support panels, each having a top edge, a bottom edge and two side edges,
(2) each of said central support panels being approximately the same length as one of said long side panels of said external side wall structure,
(c) said second side edge of each of said shorter panels in each of said external sidewall panel constructions being secured to one side edge of one of said central support panels, to form two separate receptacles, and
(d) a flange extending from the bottom edge of each of said external side wall panels and from each of said central support panels, said flanges being secured together to form a separate automatic-opening bottom structure for each of said two receptacles.
5. A carrier as in claim 4 including a handle structure comprising a pair of handle panels formed with one of said external side wall constructions, said handle panels being joined along a fold line, said central support panels being joined together along a fold line along said top edge, each of said central support panel structures and said handle panels having a handle hole, each of said central support panel structures being secured to one of said handle panels with said handle holes aligned, said central support panels being joined together.
6. A pair of blanks for forming a carrier, said blanks comprising
(a) a first blank forming a vertical support panel structure comprising two panels made of a first material,
(b) a second blank for forming external side wall panel structure made of a second material,
(c) said external side wall structure being adapted to be secured to said vertical support structure and having a plurality of panels adapted to be secured together to form two separate folding receptacles extending from opposite sides of said vertical support panel structure when said carrier is assembled and unfolded,
(d) each of said vertical support panels and each of said panels of said external side wall structure having a lower edge and a flange extending from said lower edge, selected ones of said flanges being adapted to be secured to an adjacent one of said flanges and diagonally foldable to form two separate automatically-unfolding bottom structures, one for each of said two receptacles,
(e) said second material being selected from the group consisting of (a) a material of the same strength as said first material, and (b) a material of a strength different from that of said first material.
7. A pair of blanks as in claim 6 said vertical support panels each having an upper edge and a lower edge and two side edges, and being secured to the other of said vertical support panels along a fold line forming said upper edges.
8. A pair of blanks as in claim 6 in which each of said vertical support panels has at least one fold-out portion positioned to extend into one of said receptacles and to be secured to one of said external side wall panels to form a divider for said receptacle.
9. A pair of blanks as in claim 6 in which one of said flanges for each of said receptacles is adapted to engage with structure within said receptacle so as to hold said receptacle open when said carrier is unfolded.
10. A pair of blanks as in claim 6 in which said second blank comprises two groups of side wall panels joined along fold lines, said side wall panels forming a pattern selected from the group consisting of (1) joined end-to-end, with said flanges in a linear array along one edge of said blank, and (2) parallel to one another with said flanges extending in two parallel arrays on opposite edges of said blank.
