发明名称 Flexible syringe with nozzle closure
摘要 A closure for a syringe of the feminine type wherein the nozzle of the syringe is intended to be transported separately from the flexible bag. The bag has a neck portion with a passageway adapted to receive the head of a faucet for purposes of filling the bag. The neck includes a flexible washer section and also a wall section surrounding the passageway into the neck. A hollow nozzle member has a hollow stem portion and the lower inlet end thereof has outwardly extending tooth portions and said stem portion is dimensioned to be placed in the neck portion. An outwardly extending ring portion is formed on the stem portion of the nozzle member and engages the washer section surrounding the passageway. A ring-like member is formed on the nozzle stem and in a second embodiment extends outwardly from the nozzle member and in proximity to the nozzle inlet end seats in a like sized groove formed in the neck portion of the bag. The lower tooth portions on the stem in an inserted and mounted condition in the first embodiment engages a wall section inside the bag to provide a fluid-tight engagement and a fitment so that that once the nozzle member is inserted into the neck it can only be removed with extreme difficulty.
