    • A one-piece pull-tight or strap-type security seal adapted for closing bags or the like that is designed to be easily applied in comparison with existing ones. One seal of this type has a lever operation in which a closure strap (4) is integral with a central or operating portion (2) that is, its turn, integral with a lever member (6) to which the strap may be fixed during application around the neck of a bag to be closed. The lever member is then pivoted outwardly and backwardly over the operating portion, tightening the loop so formed by means of a lever action, and then locked by security locking formations (16, 19) to effect sealing. According to the invention, the closure strap is for all effects flat, its formations for fixing it to the lever member (6) comprising a series of orifices (7) distributed along its length, whereas the immobilising formation for the closure strap comprises a first protuberance (15) adapted, on formation of the loop (25), to be received in one of the said orifices (7). The operating member (2) may be provided with an elastic hook (24) that, in the closed position of the seal, passes through another of the orifices (7) in the closure strap so as to maintain the seal closed even if the locking formations are damaged or broken. A separate seal (26) is also described, in one embodiment, so as to permit uses of the one-piece seal (1) after the first use when the security locking formations 816, 19) have already been damaged or broken.
    • 适用于封闭袋子等的一体式拉紧或带状安全密封件,其设计成与现有的相比容易应用。 这种类型的一个密封件具有杠杆操作,其中关闭带(4)与中心或操作部分(2)成一体,中心或操作部分(2)与杠杆构件(6)成一体,在该部件 应用在一个袋子的颈部封闭。 杠杆构件然后在操作部分上向外和向后枢转,通过杠杆作用紧固如此形成的环,然后由安全锁定结构(16,19)锁定以实现密封。 根据本发明,封闭带用于所有效果平坦,其结构用于将其固定到杠杆构件(6),其包括沿着其长度分布的一系列孔口(7),而用于封闭带的固定装置包括第一 在所述孔(7)中的一个上接纳的循环(25)形成的突起(15)。 操作构件(2)可以设置有弹性钩(24),其在密封件的关闭位置中穿过封闭带中的另一个孔(7),以便即使锁定 地层损坏或破损。 在一个实施例中,还描述了单独的密封件(26),以便当安全锁定结构816,19)已经被损坏或破裂时允许在第一次使用之后使用一体式密封件(1)。
