A solid composition stick applicator is provided. The applicator comprises an applicator body having a first and second end, the second end having an opening through which a solid composition stick is dispensed. Within the applicator is housed a helical tension spring having a first spring end and a second spring end, the first spring end, second spring end, or both the first and second spring end held at a fixed position with respect to the applicator body. The helical tension spring is wound around a guide system that is housed within the applicator body. A pushing assembly is attached to the helical tension spring and the pushing assembly is movable from a first position at or near the first end of the applicator body, to a second position at or near the second end of the applicator body. Tension within the helical tension spring is greater in the first position than in the second position thereby urging the pushing assembly towards the second end of the applicator body. The use of a helical tension spring within the applicator greatly increases the life of the applicator under field conditions.

Solid composition stick applicator

An applicator for a circular arc-shaped solid composition comprises a housing defining a conduit that is sized to accept the circular arc-shaped solid composition stick. The conduit has a first end and a second end, the second end being open, and has a continuous circular arc-shape from the first end to the second end. The housing also contains one, or more than one opening for engaging a fastener. Each one of the one, or more than one opening is of a sufficient size to permit at least partial lateral movement of the fastener. Also included in the housing are an inlet and an outlet in communication with the conduit, the outlet being in communication with the second end, and a biasing assembly for advancing the circular arc-shaped solid composition stick within the conduit. The position of the applicator of the present invention relative to a surface to be treated can be easily adjusted by laterally sliding the housing of the applicator relative to its mounting bracket.
