Container for produce and the like having releasably securable flaps

Claim 2

A container for produce or the like comprising: a floor panel; a pair of sidewalls; at least one cover flap movable between open and closed positions and having at least one end tab; a pair of endwalls to which said floor panel and said sidewalls are attached, at least one of said endwalls having a recess on a top surface thereof to receive said tab when said flap is in said closed position, said recess including an undercut portion adapted to interlock with said tab and prevent said flap from moving toward said open position; and a joiner strip bendably connected to one of said sidewalls along one edge thereof and bendably connected to said flap along an opposite edge thereof, whereby said joiner strip permits both lateral and pivotal movement of said flap to engage and disengage said tab from said undercut portion.

Claim 3

The container of claim 1 wherein said recess includes an additional undercut portion arranged to interlock with said tab and prevent movement of said tab and flap toward said open position upon lateral movement of said tab away from said first-mentioned undercut portion.

Claim 4

The container of claim 1 wherein said flap, said joiner strip and said sidewall to which said joiner strip is connected are integrally formed of a single piece of material and are divided from each other by scorelines.

Claim 5

The container of claim 3 wherein said endwalls are plastic.

Claim 6

The container of claim 3 wherein said endwalls are formed of expanded polystyrene.

Claim 7

The container of claim 1 wherein said recess has an entrance portion of reduced lateral dimension such that said end tab must be bowed to be inserted therein.

Claim 8

The container of claim 6 wherein said joiner strip does not extend the full width of said flap, leaving an indentation at each end thereof that facilitates flexing of said flap.

Claim 9

A generally rectangular container for produce or the like comprising: a floor panel; a pair of parallel sidewalls extending upwardly; a pair of cover flaps each movable between an open position and a closed position, each of said flaps having an end tab on each of two opposite ends thereof; a pair of endwalls to which said floor panel and said sidewalls are rigidly secured, each of said endwalls having a pair of recesses that receive said tabs when said flaps are in said closed positions, said recesses having undercut portions adapted to interlock with said tabs to prevent said flaps from moving toward said open positions; and a pair of elongated joiner strips each bendably connected to one of said sidewalls along one edge thereof and bendably connected to one of said flaps on an opposite edge thereof, whereby said joiner strips permit both lateral and pivotal movement of said flaps to engage and disengage said tabs and said undercut portions.

Claim 10

A generally rectangular container for produce or the like comprising: a floor panel; a pair of parallel sidewalls extending upwardly; a pair of cover flaps each movable between an open position and a closed position, each of said flaps having an end tab on each of two opposite ends thereof; a pair of endwalls to which said floor panel and said sidewalls are rigidly secured, each of said endwalls having a pair of recesses that receive said tabs when said flaps are in said closed positions, said recesses having undercut portions adapted to interlock with said tabs to prevent said flaps from moving toward said open positions; and a pair of elongated joiner strips each bendably connected to one of said sidewalls along one edge thereof and bendably connected to one of said flaps on an opposite edge thereof, whereby said joiner strips permit both lateral and pivotal movement of said flaps to engage and disengage said tabs and said undercut portions.

Claim 11

The container of claim 8 wherein each of said recesses includes an additional undercut portion arranged to interlock with a corresponding one of said tabs and prevent movement of said tab toward said open position upon lateral movement of said tab away from a corresponding one of said first-mentioned undercut portions.

Claim 12

The container of claim 8 wherein said flaps, said joiner strips and said sidewalls are integrally formed of a single piece of material and are divided from each other by scorelines.

Claim 13

The container of claim 8 wherein said floor panel, sidewalls, joiner strips and flaps are integrally formed of a single sheet of corrugated paperboard and are divided from each other by scorelines.

Claim 14

The container of claim 11 wherein said endwalls are formed of expanded polystyrene.

Claim 15

The container of claim 8 wherein each of said endwalls is generally rectangular having an upwardly projecting center lug and a pair of upwardly projecting end lugs, each of said recesses being between one of said center lugs and one of said end lugs.

Claim 16

The container of claim 8 wherein each of said recesses has an entrance portion of reduced lateral dimension such that said tabs must be bowed to be inserted therein.

Claim 17

The container of claim 14 wherein each of said joiner strips does not extend the full width of the connected one of said flaps, leaving an indentation at each end thereof that facilitates flexing of said flap.

Claim 18

A generally rectangular container for produce or the like comprising: a corrugated paperboard wrapper divided by scorelines into a floor panel, a pair of parallel sidewalls, a pair of elongated joiner strips of lesser width connected to the sidewalls, and a pair of cover flaps connected to said joiner strips, each of said cover flaps having a pair of tabs on opposite ends thereof; and a pair of expanded polystrene endwalls to which said floor panel and said sidewalls are rigidly connected, each of said endwalls having a pair of upwardly projecting end lugs and a center lug of equal height defining a pair of recesses in which said tabs can be received, each of said recesses having an entrance portion dimensioned to permit said tabs to enter said recesses when slightly bowed and a pair of undercut portions at opposite ends thereof positioned to interlock with said tabs to prevent said tabs from moving upwardly toward open positions.

Claim 19

A generally rectangular container for produce or the like comprising: a corrugated paperboard wrapper divided by scorelines into a floor panel, a pair of parallel sidewalls, a pair of elongated joiner strips of lesser width connected to the sidewalls, and a pair of cover flaps connected to said joiner strips, each of said cover flaps having a pair of tabs on opposite ends thereof; and a pair of expanded polystrene endwalls to which said floor panel and said sidewalls are rigidly connected, each of said endwalls having a pair of upwardly projecting end lugs and a center lug of equal height defining a pair of recesses in which said tabs can be received, each of said recesses having an entrance portion dimensioned to permit said tabs to enter said recesses when slightly bowed and a pair of undercut portions at opposite ends thereof positioned to interlock with said tabs to prevent said tabs from moving upwardly toward open positions.
