Abstract
A dilator for use in a bovine animal's teat for controlling the flow of fluid from the teat is packaged in an envelope containing a disinfectant solution. A collapsible dispensing bag containing material, as antibiotics, is located within the envelope. An elongated dispensing tube connected to the bag carries the material from the bag to the teat duct accommodating the dilator. The envelope has releasable seals which permit the envelope to be opened to expose the dilator. The envelope is used as a cover to maintain the dilator in a sterile condition as it is inserted into the duct of the teat. The material in the bag is moved from the bag by applying a squeezing force to the envelope and bag. After all of the material is squeezed from the bag, the dispenser and envelope are removed from the teat and dilator.
