    • The hinged flap of a plastic container closure is molded while in an open position and, during molding of the flap, hinged strips with depending pins are formed along the sides of the flap and are integrally connected with the flap by tearable webs. After the flap has first been closed, the pins are anchored to the top of the closure and prevent the flap from opening during shipment of the container. Initial opening of the flap is effected by swinging the flap upwardly with a substantial force to tear the webs and separate the webs from the strips and the anchor pins, the torn webs providing a visual indication that the flap has been opened.
    • 塑料容器封闭件的铰接翼片处于打开位置时被模制,并且在翼片成型期间,沿着翼片的侧面形成具有悬垂销的铰接条,并且通过可撕开的网片与翼片一体地连接。 在瓣片首先关闭之后,销钉被固定到封盖的顶部并且防止在容器运输期间瓣片打开。 翼片的初始打开是通过以相当大的力向上摆动翼片来实现的,以撕开腹板并将腹板与条和锚定销分开,撕开的腹板提供瓣片已打开的视觉指示。

    • Three hinged flaps of a plastic container closure are molded while in open positions and, during molding of the flaps, an elongated tear-away strip is formed along the front edges of the flaps and is integrally connected to the flaps by tearable webs. After the newly molded flaps have first been closed, the strip is anchored releasably to the top panel of the closure and prevents the flaps from opening during shipment of the container, the strip also serving as a visual indicator that the seal of the closure is intact. The closure is opened by lifting and pulling on the strip to tear the latter completely away from the top panel and the flaps and to free the flaps for swinging to open positions. The absence of the strip or the presence of a partially torn strip indicates that tampering has occurred and that the seal may not be intact.
    • 塑料容器封闭件的三个铰链翼片在打开位置时被模制,并且在翼片成型期间,沿翼片的前边缘形成细长的撕开条,并且通过可撕开的网一体地连接到翼片。 在新成型的翼片首先被关闭之后,条带被可释放地锚固到封盖的顶板上,并防止在容器运输过程中襟翼打开,条带也用作视觉指示器,使得封盖的密封完好无损 。 通过提起和拉动带材来打开封闭件,使封盖件完全远离顶板和襟翼,并释放襟翼以摆动到打开位置。 没有条带或部分撕裂的条带的存在表明已经发生篡改,并且密封件可能不完整。
