Pesticide delivery and dispensing system

摘要

A pesticide delivery system includes a service box and a plurality of tubular delivery and dispensing lines for carrying a pesticide from the service box to locations in a building structure and dispensing the pesticide in those locations to control and exterminate pests. The service box includes a plate with holes through which elastic end portions of the tubular delivery and dispensing lines pass. Each of the holes has a conical frustum shaped portion and an annular edge portion that has the smallest diameter of the hole and is less in diameter than an outside diameter, in an unstressed or unstretched state, of the elastic end portion of the tubular delivery and dispensing line passing through the hole whereby the annular edge portion of the hole grips and locks the tubular delivery and dispensing line in place.
