Abstract

A soil sampler liner with areas of reduced wall thickness is defined by a continuous wall that has a reduced area extending along at least a portion of the length of the liner. The liner is inserted into the inner bore of a sampler probe, and a soil sample is taken by vertically inserting the probe and liner into the ground. The wall of the liner has at least two distinct areas of varying thickness; a reduced wall area and wall areas adjacent to the reduced wall area. The walls are sufficiently strong to withstand the forces applied to the liner when taking relatively large-diameter soil samples. The thickness of the wall at the reduced wall area is less than the thickness of the wall at the adjacent areas to permit a user to easily and safely cut through the wall at the reduced wall area and remove a large-diameter soil sample from the liner. The liner is also radially compressible into a flattened shape for compact and economical packaging and shipment of liners in relatively large quantities.
