Claim 4
Dependent Claim
31 words
A foldable container according to claim 1 wherein said means for releasable securing said pin means includes at least one of a split pin, a bolt, a screw, and a wedge.
Claim 5
Dependent Claim
79 words
A foldable container according to claim 1 wherein said oblong slots are open in the upper region thereof and said means for releasably securing said pin means includes a means disposed on one of said first and second walls defining said oblong slot for constricting the opening thereof to a width which is smaller than the cross-sectional size of said pin means, said pin means for constricting being elastically enlargeable to release said pin means from said oblong slot.
Claim 6
Dependent Claim
31 words

Claim 8
Dependent Claim
50 words
A foldable container according to claim 4 wherein one of said first and second walls defining said oblong slots is of a greater vertical height than the other of said walls and is provided with a spring-pretensioned means for constricting the opening of said oblong slots to a smaller width.
Claim 9
Dependent Claim
22 words
A foldable container according to claim 7 wherein the opening of said oblong slots is arranged toward the interior of the container.
Claim 10
Dependent Claim

Claim 11
Dependent Claim
22 words
A foldable container according to claim 1 wherein said oblong slots are formed in respective corner brackets fixed to said frame member.
Claim 12
Dependent Claim
47 words
A foldable container according to claim 1 wherein one of said walls defining said oblong slots is a portion of a side edge of one of the walls forming the sides of the container and said pin means are hinge bolts threadably engageable with said side edge.
Claim 13
Dependent Claim
44 words
A foldable container according to claim 11 wherein said means for releasably securing includes in the other of said walls defining said oblong slot includes an opening the cross-sectional size of which is at least equal to the cross-sectional size of said hinge bolts.
Claim 14
Dependent Claim
