Patent ID: 8371066

Claim:
A device with a store of water for growing a lawned surface, comprising: a trough having a bottom wall, side walls, and a plurality of sections, so as to allow said trough to contain a liquid; and a tray having a plurality of sections fitting into the trough, each section being configured to support a growing substrate while nested within said trough, and having at least one well with a bottom surface, the well communicating with the liquid contained in the trough, each section of the tray including a substantially flat portion surrounding a relatively upper portion of the at least one well, wherein the trough includes a frangible region between the sections and delimited by vertical partitions extending from the bottom wall, and the tray includes a frangible region between the sections and delimited by ribs traversing the tray and extending from said substantially flat portion over a lesser height than said partitions, said tray including a different geometry from said trough via at least a differences between respective positions and extents of said partitions and said ribs on said trough and said tray, wherein the vertical partitions and ribs create boundaries along the frangible regions of the trough and the tray respectively, the boundaries of the trough and the tray being in continuous alignment across and entire width of the tray, wherein the partitions and the ribs are disposed in substantial vertical alignment with each other, the frangible regions of the trough and the tray are disposed in substantial vertical alignment with each other, and a severing of the frangible regions divides the sections of the tray and trough from the device, wherein the trough has, in the side walls, a shoulder placed at a height equal to that of the partitions, and against which a periphery of the tray rests, and wherein at least one notch is made in a peripheral rim of the trough.
