Claim:
A container system comprising a plurality of containers assembled to form a two-dimensional composite having a positive connection between adjacent containers of said plurality of containers, each container of said plurality of containers being fillable with a liquid and comprising: a lock; at least one plane surface; an irregular first form molded onto and projecting from a basic form of said container, said irregular first form having a first geometry comprising a first constriction; an irregular second form molded onto and projecting from said basic form of said container, said irregular second form having a second geometry comprising a second constriction; an irregular third form projecting into said basic form of said container to form a first recess comprising a first narrowing, said irregular third form having a third geometry corresponding to said first geometry of said first irregular form; wherein at least one of said irregular first form, said irregular second form, said irregular third form and said irregular fourth form is provided with a bore and a stopper sealing said bore, wherein said bore is arranged in a trough formed in said at least one of said irregular first form, said irregular second form, said irregular third form and said irregular fourth form an irregular fourth form projecting into said basic form of said container to form a second recess comprising a second narrowing, said irregular fourth form having a fourth geometry corresponding to said second geometry of said second irregular form; wherein said first geometry of said first irregular form is different from said second geometry of said second irregular form and said third geometry of said third irregular form is different from said fourth geometry of said fourth irregular form; wherein in order to connect said container to a first adjacent container of said plurality of containers, said irregular first form of said container engages the irregular third form of said first adjacent container and extends into the plane surface of said first adjacent container; and wherein in order to connect said container to a second adjacent container of said plurality of containers, said irregular second form of said container engages the irregular fourth form of said second adjacent container and extends into the plane surface of said second adjacent container.
