Abstract
A tree medication capsule is disclosed as including a vial having a medication sealed therein by means of an end cap; the vial, medication and end cap constitute a self-contained unit which is inserted into a predrilled hole in a tree. The vial is made of frangible material so that upon breaking, as by a mallet tap on the end cap, the medication is free to escape into the tree.

A tree medication capsule adapted to be inserted into a bore of a tree comprising
- a vial having a diameter smaller than the bore's diameter,
- a medication disposed in said vial,
- an end cap sealingly closing said vial to retain the medication therein,
- ridge means on said end cap having a diameter larger than the bore's diameter to retain said capsule in the bore of the tree,
- finger means extending from said end cap in spaced relation to said ridge means to grip adjacent portions of said vial,
- said vial, said medication and said end cap forming a self-contained capsule which is insertable as a unit into a bore in a tree, and

- a medication disposed in said vial,
- an end cap sealingly closing said vial to retain the medication therein,
- said end cap being made of semi-flexible plastic material and including a first end having a solid wall abutting said vial to close the same, an opposite end having a thin hollow wall conforming to and engaging a peripheral end portion of said vial, and a plurality of spaced fingers extending from said thin hollow wall to grip adjacent portions of said vial,
- a plurality of spaced annular ridges of said end cap, each of which has a diameter larger than said bore's diameter and tapers inwardly in a direction toward said spaced fingers, said annular ridges being adapted to be wedged into said tree bore to prevent leakage of the medication out of said tree bore, and one of said annular ridges cooperating with said solid wall to close and seal said tree bore,
- said vial, said medication and said end cap forming a self-contained capsule which is insertable as a unit into a bore in a tree, and
