Hermetically sealed container including a nozzle with a sealing bead |
摘要 |
A hermetically sealed, molded thermoplastic dispensing container is provided which includes a nozzle having a resilient and unitary annular bead about the periphery thereof. The nozzle is sized to receive the hub of a dispensing assembly in a mating relationship and the bead provides a secure friction fit and liquid seal between the hub and the nozzle. The method of forming a container with a nozzle having such a bead includes the use of seal molds having a groove conforming to the shape of the bead and a vacuum passage in communication with such groove and the step of creating a vacuum through the passage and the groove to pull a portion of a parison into the groove to form the bead.
