    • A reseable flexible thermoplastic bag including a front wall (21) and a back wall (22), said walls being joined along the major portions of their opposite longitudinal edges and bottom; an open mouth adjacent to the top edge of said bag; a closure near the open mouth of said bag including an adhesive strip (30) affixed to a first inner surface of one of a front wall or rear wall of a bag at a preselected distance from the opening of the bag; and a flap member strip (40) affixed to a second inner surface of one of a front wall or rear wall of a bag at a preselected distance from the opening of the bag; said flap member of said bag being pressable against and into said adhesive strip on said first inner surface, whereby a seal is formed by contacting said adhesive strip with said flap member of said second inner surface.
    • 一种可重复的柔性热塑性袋,包括前壁(21)和后壁(22),所述壁沿其相对的纵向边缘和底部的主要部分连接; 邻近所述袋的顶部边缘的开口; 在所述袋的开放口附近的封闭物包括粘合剂条(30),该粘合剂条(30)以与袋的开口预选的距离固定到袋的前壁或后壁之一的第一内表面; 以及折叠构件条(40),其以与袋的开口预选的距离固定到袋的前壁或后壁之一的第二内表面上; 所述袋的所述折板构件可压靠在所述第一内表面上的所述粘合带中,由此通过使所述粘合带与所述第二内表面的所述折板构件接触而形成密封。

    • A reclosable fastener assembly having two interlocking profiles with uppermost closure elements and bottommost closure elements and a slider for moving between a closed position and an open position along the profiles in straddling relation. The slider has a top and side walls depending from opposite sides of the top for receiving the profiles therebetween. The side walls extend downward from the top to a point at or below the profiles, and the side walls extend from a separating end of the slider to a pinching end. The side walls have a greater spacing at the separating end than at the pinching end, but close enough at the pinching end to press the first and second profiles into an interlocked relationship as the slider is moved toward the closed position. The slider has a separating leg depending from the top between the first and second side walls at the separating end of the slider. The separating leg is inserted past at least one of the uppermost closure elements of the profiles, but not between the bottommost closure elements. In a second aspect, the fastener assembly includes means for holding the bottommost closure elements in interlocked relationship when the slider is in the closed position, such that the bottommost closure elements are in interlocked relationship throughout their entire length.
    • 具有两个互锁轮廓的可重新闭合的紧固件组件,其具有最上面的闭合元件和最底部的闭合元件,以及滑块,用于沿着跨接关系沿着轮廓在关闭位置和打开位置之间移动。 滑块具有从顶部的相对侧悬垂的顶壁和侧壁,用于接收它们之间的轮廓。 侧壁从顶部向下延伸到在轮廓处或下方的点,并且侧壁从滑块的分离端延伸到夹持端。 侧壁在分离端处比在夹持端处具有更大的间隔,但是在夹持端处足够接近以在滑块朝向关闭位置移动时将第一和第二轮廓压紧成互锁关系。 滑块具有从滑块分离端处的第一和第二侧壁之间的顶部分离的分离腿。 分离腿被插入到轮廓的至少一个最上面的闭合元件中,而不是在最下面的闭合元件之间。 在第二方面,紧固件组件包括用于当滑块处于关闭位置时将互锁关系中的最底部的闭合元件保持的装置,使得最底部的闭合元件在整个长度上处于互锁关系。
