Abstract

A tray having wells or depressions therein for holding a medicament or material and an applicator for applying the medicament or material. The applicator well has one open end from which a portion of the applicator extends. A cover seals the medicament or material well and the applicator well and a portion of the applicator. In one embodiment, the cover is a thin sheet or film that adheres or is heat sealed to substantially the entire surface of the tray. The portion of the applicator extending beyond the applicator well is used to facilitate the removal of the cover whereby the extended portion of the applicator acts as a lever to pry the cover form the body of the tray. Additionally, packaging material required to form the tray can be substantially lessened in those cases where the applicator that is relatively large in comparison with the amount of material to be packaged. Therefore, a larger applicator that is easy to use is associated with the material without unnecessary packaging. The dispenser or package permits small quantities of material to be easily dispensed for a single use or a single patient dose. Retaining means are provided for securing the applicator by friction fit within the applicator well. In another embodiment, a hinged cover is used in combination with a tray having multiple material wells which may be jointed or separately opened and closed.
