Abstract: An elongate hollow body of frusto conical tubular formation having a plurality of internal prongs resiliently projecting obliquely into the hollow of the body obliquely away from the larger body end, and a closure on the smaller body end, the body being constituted of longitudinal sections swingable relative to each other for opening the body to remove an occupant.

Abstract: A plant container adapted to be fabricated from an integral blank of plastic sheet material and comprising a bottom wall, a peripheral side wall upstanding about the bottom wall, and a cover of a plurality of flaps extending laterally inwardly from the side wall with opposed flaps terminating short of each other to define therebetween a central passageway for the stem of a plant, the flaps being spaced below the top of the side wall to effectively limit the quantity of falling water received in the container by causing excess to overflow.

Abstract: A sheet cutting method and apparatus wherein a fluid pervious die plate or wall having projecting cutting edges is located facing a sheet to be worked, and a vacuum is transmitted through the wall to draw the sheet against the cutting edges for severance of the sheet.

Abstract: A handling system fabricated essentially of sheet material including a container defined by a tube of polygonal cross section having end tabs extending into overlapping relation with their overlapping portions secured together; a tray for a plurality of said containers including a lower support wall, upstanding flaps extending in end to end relation about the support wall and fastener means also fabricated of sheet material and securing together the ends of the flaps; a generally cylindrical tube adapted to rest endwise on the support wall with portions generally tangent to the flaps, and similar fastener means secured to the adjacent flap and cylinder portions; and the fastener means specifically including overlying sheet portions having cuts defining overlying strips displaceable away from the remainder of the sheet portions, an insert extendable through and beyond the space between displaced strips and adjacent sheet portions, and a tool for guiding the insert into position and removable from the insert to

Abstract: A container system for plant husbandry including a plurality of trays having removable partitions subdividing the trays into relatively small growing compartments, a plurality of open-ended tubes removably upstanding in said trays and having additional removable partitions subdividing the tubes into intermediate growing compartments, the tubes providing large growing compartments upon removal of the tube partitions.
