    • The application describes breakable seal for a container, bag, pouch or reusable envelope which is closed by one part locating over a second part, the second part having an opening for receiving the head of the breakable seal which locks into the opening in such a manner that it cannot be removed without breaking, the seal in its inserted position locking the first part in place over the second part in a tamper evident fashion. The seal has an extended neck portion between the line of weakness and the main body part of the seal. Typically said one part is the fastener tab of the zipped opening of a reusable envelope and the second part is the enclosure or chamber of a lock unit mounted on the envelope, adjacent one end of the zipped opening.
    • 本申请描述了容器,袋,小袋或可重复使用的信封的可破坏的密封件,该容器,袋子,袋或可重复使用的封套由位于第二部分上的一个部分封闭,第二部分具有用于接收以这种方式锁定到开口中的可破坏密封件的头部的开口 它不能在不破裂的情况下被移除,其插入位置中的密封件以明显的篡改方式将第一部分锁定在第二部分上。 密封件在弱点线与密封件的主体部分之间具有延伸的颈部。 通常所述一个部分是可重复使用的信封的拉链开口的紧固件突出部,并且第二部分是安装在信封上的锁定单元的外壳或室,邻近拉链开口的一端。

    • There are disclosed two embodiments of a fastener, a method of using a fastener, and a fragmentary portion of a mold. The fastener has a socket and a head joined by a flexible filament. The socket has a disc-shaped body, a transverse opening through the body, projections extending into the opening, and a post joined to each projection. The posts extend into the space within a side wall of the opening. The projections flex when the head is inserted through the opening, but the posts prevent attempted withdrawal of the head through the opening thereby preventing uncoupling of the head from the socket. The projections are so close that when the head is inserted into the socket, some of the plastics polymeric material of the projections deforms permanently, thereby work hardening the projections at the deformation.
    • 公开了紧固件的两个实施例,使用紧固件的方法和模具的部分部分。 紧固件具有插座和由柔性灯丝连接的头部。 插座具有盘形主体,穿过主体的横向开口,延伸到开口中的突起和连接到每个突起的柱。 柱延伸到开口的侧壁内的空间中。 当头部穿过开口插入时,突出物弯曲,但是柱防止了头部通过开口的尝试撤回,从而防止头部与插座脱开。 突出部分非常接近,当头部插入插座时,突起的一些塑料聚合物材料永久地变形,从而在变形时对突起进行硬化。

    • A seal formed of molded resilient plastic material, including a housing through which a shackle is passed, said housing having internal integral shackle engaging fingers. The shackle is provided with annular shoulders for engagement by the fingers so that the shackle can be drawn through the housing in one direction, but is prevented from retrograde movement. The end portion of the shackle is provided with annular enlarged portions which may be drawn through the housing without excessive pulling force being required, yet provides a surface providing for gripping by the fingers. A portion of the shackle between two adjacent annular shoulders is provided with a weakened portion to insure that when sufficient tension is applied, the shackle will fracture at that position, with said position being predetermined for the application in which the seal is to be used, so that the fracture occurs within the housing.
