摘要： The claimed invention relates to a container assembly for applying grease to the ball of a trailer hitch. Specifically, the grease applicator comprises a lower housing with an upper concave surface and an upper housing with an upper concave surface further comprising at least one aperture. Grease is introduced between the upper concave surface of the lower housing and the upper concave surface of the upper housing such that when the two surfaces are pressed together grease is emitted from the at least one aperture in the upper concave surface.

摘要： A fletching system including a sleeve positionable about an outer surface of an arrow shaft and at least one archery vane mounted to an outer surface of the sleeve. The sleeve has an initial inner diameter greater than an outer diameter of the arrow shaft and the sleeve is shrinkable to secure the fletching system to the arrow shaft. Methods for constructing a fletching system include mounting a shrinkable sleeve and at least one archery vane on an outer surface of the shrinkable sleeve and also attaching the fletching system with respect to an archery arrow.
