Abstract
Thermoformed double tray system for cultivation of plants including a top tray which is stacked with a bottom tray. The top tray has cells for receiving a substrate. The bottom tray provides rigidity to the double tray system. The bottom tray has a baseplate which is provided with support elements to support the top tray. The baseplate has an outer edge which defines the outer contour of the bottom tray. A groove shaped deepening in the baseplate is extending in parallel with the outer edge. The deepening increases a bending stiffness of the bottom tray and provides rigidity to the double tray system. The deepening is provided with a reinforcing ribs which cross the deepening.
Claims15
A double tray system for cultivation of plants comprising:
- a top tray including a plurality of cells for receiving a substrate, wherein each cell includes a cell space which is defined by a circumferential cell wall and a cell bottom;
- and
- a bottom tray for supporting the top tray, the bottom tray including a baseplate, wherein the baseplate comprises:
- a bottomside;
- a topside;
- a plurality of supporting elements for supporting the top tray, said supporting elements project at the topside away from the baseplate, wherein the baseplate has an outer contour which is delimited by an outer edge;
- and
- a groove shaped deepening which is open at the bottomside of the baseplate, said groove shaped deepening protrudes at the topside away from the baseplate, said groove shaped deepening is elongated and extends in a longitudinal direction in parallel with the outer edge of the baseplate,
- wherein the groove shaped deepening includes a plurality of ribs formed on the bottomside of the baseplate, the ribs and the supporting elements separating the groove shaped deepening into a plurality of groove shaped pockets and each rib extends in a direction transverse the longitudinal direction of the respective groove shaped pocket,
- wherein the ribs are positioned external from the supporting elements,
- wherein each groove shaped pocket is positioned adjacent to at least one of the plurality of supporting elements,
- wherein each rib is positioned between a pair of neighboring supporting elements of said plurality of supporting elements, and
- wherein the outer edge surrounds and is spaced from the groove shaped deepening.
A bottom tray for a double tray comprising:
- a baseplate including:
- a bottomside;
- a topside;
- a plurality of supporting elements for supporting a top tray, said supporting elements project at the topside away from the baseplate, wherein the baseplate has an outer contour which is delimited by an outer edge;
- and
- a groove shaped deepening which is open at the bottomside of the baseplate, said groove shaped deepening protrudes at the topside away from the baseplate, said groove shaped deepening is elongated and extends in a longitudinal direction in parallel with the outer edge of the baseplate,
- wherein the groove shaped deepening includes a plurality of ribs formed on the bottomside of the baseplate, the ribs and the supporting elements separating the groove shaped deepening into a plurality of groove shaped pockets and each rib extends in a direction transverse the longitudinal direction of the respective groove shaped pocket,
- wherein the ribs are positioned external from the supporting elements,
- wherein each groove shaped pocket is positioned adjacent to at least one of the plurality of supporting elements,
- wherein each rib is positioned between a pair of neighboring supporting elements of said plurality of supporting elements, and
- wherein the outer edge surrounds and is spaced from the groove shaped deepening.
