Claims17
A container and lid assembly, including a container comprising a base and four side walls extending upwardly therefrom and terminating at an upper annular rim, and a lid having a closed top portion and an inverted U shaped ledge extending along the periphery of said top portion, said ledge having an interior wall, an exterior wall, and a top wall, said ledge having an internal dimension cooperative with an external dimension of said container annular rim so as to snugly engage said container annular rim, said improvement comprising:
- first and second elevated reinforcement means, oriented on said lid top portion, for assisting in preventing deformation of said lid upon an impact, said first elevated reinforcement means disposed approximately adjacent the entire perimeter of said ledge interior wall and said second elevated reinforcement means being substantially X shaped and oriented centrally on said lid, said second elevated reinforcement means intersecting with said first elevated reinforcement means approximately adjacent to the corners of said lid, the height of said first and said second elevated reinforcement means being approximately equal, said ledge having substantially C shaped recesses formed in approximately said lid corners, such that the internal dimensions of said ledge in said corners are less than the internal dimensions of the remainder of said ledge.
A container and lid assembly including a container comprising a base and four side walls extending upwardly therefrom and terminating at an upper annular rim, and a lid having a closed four sided top portion and an inverted U shaped ledge extending along the periphery of said four sided top portion, said ledge having an interior wall, an exterior wall, and a top wall, said ledge having an internal dimension cooperative with an external dimension of said container annular rim so as to snugly engage said container annular rim, said improvement comprising:
- first and second elevated reinforcement means, oriented on said lid top portion, for assisting in preventing deformation of said lid upon an impact, said first elevated reinforcement means oriented adjacent said ledge interior wall end said second elevated reinforcement means being X shaped and oriented centrally on said lid, said second reinforcement means extending towards the corners of said lid, said ledge having C shaped recesses formed in approximately said lid corners, said first and second reinforcement means forming at least one triangularly shaped section on said lid top portion;
- said ledge interior wall further including two recesses disposed in each side of said ledge;
- at least one retaining means oriented adjacent said ledge exterior wall on each side of said lid and extending in a substantially downward direction from said ledge exterior wall, said retaining means positioned to underlie said annular rim when said container end said lid are secured together, said container and said lid being secured together until two adjacent retaining means are simultaneously released from said annular rim.
A container and lid assembly comprising a container having a base and an outer wall extending upwardly therefrom and terminating at an upper rim, and a lid having a closed top portion and an inverted U shaped peripheral ledge defining a wall of said top portion, said ledge having an interior wall, top wall, and an exterior wall, said ledge having dimensions cooperative with dimensions of said upper rim such that said upper rim is engaged by said ledge, the improvement comprising:
- said lid having elevated first reinforcement mean and a second reinforcement means said first reinforcement means oriented on said top portion for assisting in preventing deformation to said lid upon an impact, said first reinforcement means being elevated with respect to said top portion and said first reinforcement means extending in a substantially outward direction towards said ledge interior wall from a center of said lid top portion, and said second reinforcement means oriented adjacent said ledge interior wall and engaging said first reinforcement means interiorly of said ledge interior wall, the elevation of said first and second reinforcement means being approximately equal, said first reinforcement means further comprising first rib members forming a substantially X shape centrally oriented on said lid top portion, and second rib members forming a substantially spoke shape centrally oriented on said lid top portion, said first and second rib members extending in a substantially outward direction from said center of said lid top portion.
A container and lid assembly comprising a container having a base and an outer wall extending upwardly therefrom and terminating at an upper rim, and a lid having a closed top portion and an inverted U shaped peripheral ledge defining a wall of said top portion, said ledge having an interior wall, top wall, and an exterior wall, said ledge having dimensions cooperative with dimensions of said upper rim such that said upper rim is engaged by said ledge, the improvement comprising:
- said lid having elevated first reinforcement means and a second reinforcement means said first reinforcement means oriented on said top portion for assisting in preventing deformation to said lid upon an impact, said first reinforcement means being elevated with respect to said top portion and said first reinforcement means extending in a substantially outward direction towards said ledge interior wall from a center of said lid top portion, and said second reinforcement means oriented adjacent said ledge interior wall and engaging said first reinforcement means interiorly of said ledge interior wall, the elevation of said first and second reinforcement means being approximately equal, said lid further comprising at least three retaining means oriented adjacent said ledge exterior wall, said retaining means positioned to underlie said annular rim when said container and lid are secured together, said retaining means preventing said container and said lid from being separated unless two adjacent retaining means are simultaneously released from said annular rim.
A quadrilateral container comprising a bottom and four side walls extending upwardly therefrom and terminating at an upper rim, and a lid having a top portion surrounded by a U shaped ledge on a periphery of said top portion, said improvement comprising:
- said ledge having internal dimensions in the four corners which are substantially less than the internal dimensions of the remainder of said ledge such that the corners of said rim are more securely retained by said ledge corners than the remainder of said rim is retained by remainder of said ledge.
