    • A valve closure for a container, having a body, a valve and a lid. The valve is positioned across the opening of the container and itself has an opening through which the contents of the container may be dispensed. The lid is moveable relative to the body between open and closed positions and is shaped to block the valve opening, when the lid is in its closed position. The lid has a projection, which forms a peripheral seal around the valve opening, when the lid is in its closed position, and within the periphery of the projection, the shape of the lid substantially conforms to the shape of the valve and / or body, to minimise the volume therebetween.
    • 用于容器的阀盖,具有主体,阀和盖。 阀定位在容器的开口处,并且其自身具有开口,容器的内容物可通过该开口分配。 盖子可在打开和关闭位置之间相对于主体移动,并且当盖子处于其关闭位置时,其形状可阻挡阀门开口。 盖子具有突起,当盖子处于其关闭位置时,该突起形成围绕阀门开口的周边密封件,并且在突出部分的周边内,盖子的形状基本上符合阀门和/或主体的形状 ,以最小化它们之间的体积。

    • A moulded polymeric container (10) includes a body portion (12) having a sidewall (18) and an integral champagne type base (16). The base (16) includes a lower end (20) that defines an annular contact ring (22) for supporting the container (10) with respect to an underlying surface. An annular step ring (24) is defined immediately radially inwardly of the annular contact ring (22) and has a radial length L S . The base (16) further has a central push-up area (26) and a generally concave transition region (28) interposed between the central push-up area (26) and the annular contact ring (22). The transition region (28) further includes a plurality of integrally moulded radially extending ribs (30), each of the ribs (30) having a length L R . According to one advantageous aspect of the invention, the ratio L R /L S is within a range of about 1.0 to about 4.0.
    • 模制的聚合物容器(10)包括具有侧壁(18)和整体式香槟型底座(16)的主体部分(12)。 基部(16)包括限定用于相对于下面的表面支撑容器(10)的环形接触环(22)的下端(20)。 环形阶梯环(24)被定义在环形接触环(22)的径向内侧,并且具有径向长度LS。 底座(16)还具有插入在中央上推区域(26)和环形接触环(22)之间的中央上推区域(26)和大致凹入的过渡区域(28)。 过渡区域(28)还包括多个整体模制的径向延伸肋(30),每个肋(30)具有长度LR。 根据本发明的一个有利方面,LR / LS的比值在约1.0至约4.0的范围内。
