  • Patent number: 8677682
    Abstract: The device is provided for collecting sap from a tapped hole of a tree. It includes a collector having a substantially frustoconical outer peripheral wall surface and an inner peripheral wall surface. The collector also has a portion that is removably insertable into the tapped hole with a frictional engagement. The material between the peripheral wall surfaces at the removably-insertable collector portion is elastically and temporality deformable in response to a peripheral pressure exerted inwardly on the outer peripheral wall surface when the removably-insertable collector portion is inserted with a forced frictional fit into the tapped hole.
