A prismatic container is used for insertion into a notch in an element in order to release a chemical agent from a container volume into the element. The container includes a plurality of first sides inclined outwardly relative to each other from at least one junction. These first sides form lateral sides of the container. A pair of second sides, parallel to each other, form longitudinal ends of the container. At least one of the first and second sides forms at least part of a cap for closing off an opening which provides access to the container volume for storage of the chemical agent. The second sides are formed of a biodegradable material which dissolves in order to release the chemical agent. Pyramidal and conical container configurations can also be utilized. |
