    • The assembly comprises a container (1) and a removable closure (2) that can be screwed onto the plastic container. Said plastic preform container (1) comprises a hollow body (11) and a neck finish (10) terminated by a wide-mouth opening (100). Said neck finish comprises a neck support ring (102) and a neck portion (101) extending between the wide-mouth opening (100) and the neck support ring (102). The neck portion (101) is provided with a thread (12) for screwing the removable closure onto the neck portion (101), and comprises an upper portion (1010) and a reinforced lower portion (1011). The inner face (1011 b) of the reinforced lower portion (1011) is transitioning to the inner face (1010b) of the upper portion (1010) along a transition step (1011 c) in such a way that said reinforced lower portion (1011) is thicker than the upper portion (1010) at least in a top part of the reinforced lower portion (1011). The removable closure (2) comprises a deformable sealing material (20) and once the removable closure is being screwed onto the neck finish of the container (1), the upper portion (1010) of the neck portion (101) is in contact with the deformable sealing material (20) and a seal is achieved only between this upper portion (1010) of the neck portion (101) and the removable closure (2).
    • 该组件包括容器(1)和可移除的封盖(2)确实能够在塑料容器被拧。 所述中空的塑料预制件的容器(1)包括主体(11),并通过一个广口开口(100)终止的颈口(10)。 所述颈口包括颈部支撑环(102)和所述广口开口(100)和所述颈部支撑环(102)之间延伸的颈部(101)。 颈部(101)上设置有用于拧可拆卸闭合走上上部(1010)和一个加强下部部分(1011)的颈部(101)和包括螺纹(12)。 增强下部的内表面(1011 b)中(1011)被转换到沿的过渡步骤(1011℃)的上部(1010)的内表面(1010B)(以寻求其中所说加强的下部1011的方式 )至少比在钢筋下部(1011)的顶部部分的上部(1010)厚。 所述可移除的封闭件(2)包括可变形的密封材料(20),并且一旦可移动封闭件被拧到容器的颈口(1),所述颈部部分(101)的上部(1010)与接触 所述可变形的密封材料(20)和一个密封件实现仅颈部(101)和所述可移除的封闭件(2)的该上部分(1010)之间。
