  • Patent number: 5379550
    Abstract: A carrier for bulbous plants on which the bulbs are disposed mutually adjacently according to a predetermined pattern, comprising a number of individual bulb holders for each bulb which are disposed in that pattern on the carrier, in addition to a liquid reservoir which belongs to each or a number of holders and which in use lies under the holders, wherein the or each liquid reservoir is provided with an overflow edge for defining the maximum liquid level in the reservoir.In preference the bulb holders are provided with fixation means for fixing the bulb.The fixation means are usually formed by protrusions, for instance pins, onto which the bulb is fixed.It is thus possible to keep constant the distance between the underside of the bulb and the water level, and use no longer has to be made of culture material and sand.

  • Patent number: 4567985
    Abstract: Nestable and stackable box comprising a rectangular bottom, two side walls and a back wall, which walls diverge, starting at the bottom, a lowered front wall and a fold-away stacking support. The front of each side wall has been bevelled off to make an obtuse angle with the top of the side wall, and each side wall has been provided with an opening near its front, the vertical plane bounding the opening at the front being totally before the perpendicular dropped from the vertex of the obtuse angle between the front and the top of the side wall upon the bottom. The part of the wall section between the opening and the front of the side wall goes outward as it goes downward, to a distance of one to three times its horizontal wall thickness, to form a ridge having a width of one to three times the horizontal wall thickness.
