ABSTRACT:
The disclosure herein describes a device for collecting sap from trees which has a sap-collecting section adapted to be inserted into the outer layers of a tree; this section displays thereon an annular recess in which is received an expansible sealing element. A second member is partially mounted over the sap-collecting section of the first member and is adapted to be moved against the sealing element so as to expand the element when the device is inserted into a tree cavity to thereby prevent air infiltration in the device when the sap-collecting system is operating under vacuum conditions.
