Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
166 words
A container for packaging liquids adapted to interengage with an identical container to define a right parallelpiped form whereby interengaged containers interlock to restrict relative displacement therebetween comprising a hollow body having first and second spaced parallel sides of right angle trapezoid form, first and second nonparallel lateral sides, and parallel upper and lower sides, said first lateral side being perpendicular to said lower side, the spacing between said lateral sides being greater adjacent said lower side than at said upper side, first engaging means defined on said second lateral side adjacent said upper side, second engaging means defined on said second lateral side adjacent said lower side, said engaging means including surfaces transversely disposed to said second lateral side and of complimentary mating configuration, third engaging means defined on said first parallel side of trapezoid form, and fourth engaging means defined on said second parallel side of trapezoid form, said third and fourth engaging means being complimentary and interengageable for engagement with adjacent like containers.
Claim 2
Dependent Claim
166 words
