HERMETICALLY SEALED CONTAINER INCLUDING NOZZLE WITH SEALING BEAD

摘要

PROBLEM TO BE SOLVED: To induce secure friction fitting and liquid seal between a hub and a nozzle by providing a hermetically sealed container with a removable closure which is integral with a nozzle which defines a dispensing aperture and an elastic annular bead which is integral with the nozzle and encloses the circumference of the arranged nozzle apart a spacing from the dispensing aperture. SOLUTION: This hermetically sealed thermoplastic container 10 comprises a main body part, a neck portion which is integral with the main body part, the nozzle 16 which extends in the direction parting from the neck portion and includes the top end defining the dispensing aperture 18 and the removable closure 20 which closes the dispensing aperture 18 and is integral with the nozzle 16. The nozzle 16 includes an outer peripheral surface 24 and the elastic and integral annular bead 26 which extends around the outer peripheral surface 24 in a circumferential direction and out side a radial direction. The bead 26 parts by a specified distance from the dispensing aperture 18 of the nozzle 16 and exists on a plane nearly parallel with the dispensing aperture 18. The bead 26 has a nearly triangular shape or fin-like cross section and includes a lower plane surface 28 and upper plane surface 30 which are apart from each other.
