    • A closure fitting is provided for a container which itself has no threads or equivalent closure securing means formed on it. The fitting, which can be pressed down over the mouth of a container, provides its own securing means by which a generally outer closure portion of the fitting can be removed from and resecured to a separable inner portion which remains attached to the container after opening. The closure fitting has a distendable conical hoop (22) moulded inside a surrounding skirt (20). Cooperating sets of threads, lugs, or the like (29, 28) are formed on the outer face of the hoop and on the inner face of the skirt. In the closure as formed, the closure securing means of the hoop and skirt do not operably engage one another. However, they are progressively brought into cooperating engagement as the hoop expands while the fitting is being press-fitted onto a container. The hoop is severably joined to the skirt; twisting or otherwise moving the closure portion in relation to the hoop in the first user operation breaks a separable connection (24) between the hoop and the skirt, so that the closure portion can be removed from the hoop. The closure portion can thereafter be used in the same manner as a conventional closure.
    • 为容器提供闭合配件,该容器本身没有形成在其上的螺纹或等效的闭合件固定装置。 可以将其压在容器的口部上的配件提供其自身的固定装置,通过该固定装置,配件的大致外封闭部分可以从打开后保持附接到容器的可分离的内部部分移除并固定。 封闭配件具有模制在周围裙部(20)内的可膨胀的圆锥形环(22)。 在箍的外表面和裙部的内表面上形成有一组螺纹,凸耳等(29,28)。 在形成的封闭件中,环箍和裙部的封闭固定装置不可操作地彼此接合。 然而,当配件被压配合到容器上时,它们逐渐变得配合接合,因为箍膨胀。 箍与裙子分开连接; 在第一用户操作中相对于环箍扭转或以其他方式移动封闭部分会破坏箍和裙部之间的可分离连接件(24),从而能够将封盖部分从箍环上移除。 之后可以以与常规封闭件相同的方式使用封闭部分。
