Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 237 words
A two piece produce box comprising: a base tray having a generally rectangular bottom panel and upstanding end walls and side walls, said end walls and said side walls being trapezoidal in shape with the narrow end of each trapezoidal wall being at the bottom of said base tray such that the perimeter of the top of said tray is larger than the perimeter of the bottom thereof, each said end wall having a pair of spaced slots therein adjacent the top edge thereof while each side wall includes a central recess in the top edge thereof and a generally rectangular lid of smaller width than the width of the base tray at the top thereof, said lid having two spaced extension fingers projecting from each end thereof for insertion into a corresponding pair of slots in each end wall of said base tray, said rectangular lid further including a central T-shaped projection extending horizontally from each side thereof for engagement with a corresponding one of said recesses in each side wall of said base tray whereby when said lid is removably locked in place in said base tray, with said T-shaped projections engaged in said recesses, the sides of the base tray apply pressure against the top of said T-shaped projections to hold said projections and the lid in place, and said T-shaped projections also function to support the intermediate span of the lid against collapse.
Claim 2
Dependent Claim 237 words
A two piece produce box comprising: a base tray having a generally rectangular bottom panel and upstanding end walls and side walls, said end walls and said side walls being trapezoidal in shape with the narrow end of each trapezoidal wall being at the bottom of said base tray such that the perimeter of the top of said tray is larger than the perimeter of the bottom thereof, each said end wall having a pair of spaced slots therein adjacent the top edge thereof while each side wall includes a central recess in the top edge thereof and a generally rectangular lid of smaller width than the width of the base tray at the top thereof, said lid having two spaced extension fingers projecting from each end thereof for insertion into a corresponding pair of slots in each end wall of said base tray, said rectangular lid further including a central T-shaped projection extending horizontally from each side thereof for engagement with a corresponding one of said recesses in each side wall of said base tray whereby when said lid is removably locked in place in said base tray, with said T-shaped projections engaged in said recesses, the sides of the base tray apply pressure against the top of said T-shaped projections to hold said projections and the lid in place, and said T-shaped projections also function to support the intermediate span of the lid against collapse.
Claim 3
Dependent Claim 58 words
A two piece box as in claim 1 wherein each of said end walls comprises: (a) an outer trapezoidal panel integrally formed with and hingedly attached to the bottom panel of said base tray, and (b) an inner lid locking panel having said spaced slots therein for receiving said extension fingers projecting from the end of said lid.
Claim 4
Dependent Claim 81 words
A two piece box as in claim 2 wherein said inner lid locking panel comprises: (a) first and second flaps each integrally formed with and hingedly attached to a corresponding one of said side walls whereby said flaps may be folded inwardly and attached to said outer trapezoidal panel to form an end wall, and (b) at least one slot in each of said flaps for receiving a corresponding one of said extension fingers projecting from the end of said lid.
Claim 5
Dependent Claim 48 words
A two piece box as in claim 1 wherein: (a) the leg of each said T-shaped projection is inserted in a corresponding one of said recesses whereby the side wall of said box is interposed between the top of said T-shaped projection and the body of said lid.
