摘要： An apparatus for molding a plastic closure includes a male mold assembly including a forming pin and an outer pin sleeve which cooperate with a female mold for defining a mold cavity. To facilitate mechanical stripping of a molded closure from the forming pin, pressurized air is introduced into the molded closure through at least one air passageway which extends axially between the forming pin and pin sleeve. By outwardly expanding and forming the plastic closure during ejection from the forming pin, forces to which the closure is subjected during ejection are significantly reduced, thereby desirably reducing the amount of cooling of the closure that is required during the molding cycle prior to ejection. Significantly increased operating speeds for the compression molding apparatus can thus be achieved.

摘要： The present invention is directed to a closure having a top wall which has a base cross-sectional thickness, a threaded portion and an annular skirt depending therefrom which includes tamper-evident means frangibly connected thereto. The top wall further comprises a stiffening block from which an inner annular seal and an outer annular seal depend. The inner annular seal is characterized by depending from a point of the stiffening block which is midway between the inner and outer periphery of the stiffening block and which is positioned to sealingly engage the inner wall of the opening of a container to which the closure is applied. The outer annular seal depends from the stiffening block in a manner such that the outer wall of the seal defines the outer periphery of the stiffening block. The stiffening block contains also a groove which defines the point of attachment of the inner wall of the outer seal and the sealing block and a step between the inner and outer seal which impinges the opening of a container to which the closure is affixed. This arrangement provides improved sealing and decoupling of stresses placed on the closure top wall from the sealing means.
摘要翻译：本发明涉及具有顶壁的封闭件，该顶壁具有基部横截面厚度，螺纹部分和从其垂下的环形裙部，其包括与其易于连接的防窃动装置。顶壁还包括加强块，内部环形密封件和外部环形密封件从该加强块构成。内部环形密封件的特征在于，从加强块的位置，该加强块位于加强块的内周和外周之间的中间，该加强块位于与密封件应用于的容器的开口的内壁密封接合。外环形密封件以加强块的方式使得密封件的外壁限定加强块的外周。加强块还包括限定外部密封件的内壁和密封块的连接点的凹槽，并且在内部和外部密封件之间的台阶，该内部密封件和外部密封件冲击盖子所固定的容器的开口。这种布置提供了改进的封闭顶壁上的应力与密封装置的密封和解耦。
