The container comprises a frame and a thin removable and discardable sleeve in all embodiments. The planting system further includes methods of planting the containers. Also, hand tools for planting the containers are disclosed.

Abstract: Multipackaging devices made of a resilient plastics-material such as low density polyethylene. The devices are made in strip form and are integrally interconnected longitudinally of the strip for continuous machine application to adjacent rows of containers with selective transverse severance of the applied strip to form individual packages of selected members of containers. The strip comprises a row of bands along each side thereof with intersecting and diagonally arranged substantially straight-line band segments extending between the side bands. The band segments cooperate with each other and with the side bands to define additional intermediate bands between the side bands. The strip is substantially narrower than the width of the rows of containers so that substantial transverse stretching of the strip is required to apply the side and intermediate bands to the rows of containers.

Abstract: A wind machine comprising a fixed or controlled pitch blade assembly to drive a variable displacement or variable clearance fluid compressor. Means which may be mechanical, hydraulic, pneumatic or electrical interconnect the blade assembly and the compressor to vary the fluid displacement or clearance volume of the compressor as a function of the drag or lift forces of the wind on the blade assembly.

Abstract: The present invention relates generally to improvements in plastic preforms adapted for telescopic association with a complementary smooth surfaced mandrel such as is used in conventional plastic blow molding machines. More particularly, the present invention contemplates a novel type of plastic preform as herein, which comprises an elongate hollow plastic member, the inner surface of which in the aggregate conforms generally with the shape defined by the smooth peripheral surface of a complementary mandrel. The inner peripheral surface of the hollow plastic member or preform below the rim portion presents a plurality of circumferentially spaced surface portions adapted for initial direct impingement with restricted areas of the peripheral surface of a complementary smooth surfaced mandrel, the spacing between the said surface areas of impingement providing passageways extending generally longitudinally throughout substantially the entire longitudinal extent of the plastic member.
