Molded container with raised nipple and method for use
This invention container comprises a container shell comprising a body portion, adjoining cap portion and enclosed stopper, and an engineered separation site to facilitate separation of body and cap. The stopper has a raised nipple on the stopper, positioned such that a portion of the stopper is enclosed within the body portion and a portion of the stopper is enclosed within the cap portion. When the cap portion is removed from the body portion, a portion of the nipple therefore extends out of the body portion, allowing easy access to the stopper for cleaning or contents removal. In addition, there is an engineered separation site which includes a partial attenuation of the thickness of part of the container wall. Raised gussets are provided to enhance the cooperation between the instant invention and various needle-free connectors known in the art.
