Abstract
A soil-sampling tool extends along a longitudinal axis and includes a barrel having a soil-penetrating distal end, and a cap for closing the end. In the improvement, the barrel has a seal surface spaced from the end and also has a tapered lead portion between the surface and the end. The lateral dimension of the lead portion is less than that of the seal surface. The cap includes an abutment face and a seal spaced therefrom. The barrel seal surface is spaced from the barrel end by a dimension not greater than that between the cap seal and its abutment face. In a highly preferred embodiment, the barrel has a stop shoulder between the barrel seal surface and the barrel end. The cap includes a lip bearing against the stop shoulder and a tapered cap face substantially contacting the barrel face of the tapered lead portion. The tool also relates to a new method.
