摘要:
A closure for a device comprises a base 50 including a valve seat 34 and configured to sealingly engage an open end of a device and form a fluid tight seal therebetween and thereby close the device; and a support 54 configured to sealingly engage the base and form a fluid tight seal therebetween. The base and the support are configured such that when the support sealingly engages the base, a one-way valve 28 is configured (a) to define an interference fit between a flexible or elastic valve member 30 and the valve seat 34 or (b) so that a portion of the valve member is not spaced away from the closed position substantially throughout any period of dispensing to maintain a hermetic seal between an inlet to the valve opening and the ambient atmosphere.
摘要(中):
用于装置的封闭件包括基座50,基座50包括阀座34并且构造成密封地接合装置的开口端并且在其间形成流体密封并由此关闭装置; 以及构造成密封地接合底座并在其间形成流体密封的支撑件54。 底座和支撑件构造成使得当支撑件密封地接合底座时,单向阀28被构造成(a)以限定柔性或弹性阀构件30与阀座34之间的过盈配合,或者(b) 使得阀构件的一部分基本上在分配的任何时间段内基本上不与闭合位置间隔开,以保持阀开口的入口与环境大气之间的气密密封。
