摘要： The present invention generally provides a threaded tamper-evident closure having an annular hook-shaped flange extending radially inward from the inner surface of the tamper-evident band attached to the bottom edge of the closure body. The hook-shaped flange can be continuous or segmented and forms an upwardly angled surface for engaging the sealing flange on the bottle neck. A plurality of elevated areas extend upwardly from the tamper-evident band in spaced relation to the bottom edge of the closure body. The frangible elements connecting the tamper evident band to the lower edge of the closure depending annular flange may be configured to extend from these elevated areas as well as the non-elevated areas of the tamper-evident band. Pairs of cooperating ratchets may be used in lieu of or in combination with the elevated bridge areas to reduce the stress placed upon frangible elements and/or during cap application. A second preferred embodiment of the present invention provides a threaded tamper evident plastic closure having a tamper-evident band containing the above-described features, for use with a tamper evident push-pull resealable pour spout which is substantially leak proof. The present invention also optionally provides a dust cover which encloses the push-pull pour spout closure when inserted on the container. The dust cover may be optionally provided with a tamper-evident sealing band which remains intact upon initial installation of the dust cover onto the container and which is broken when the dust cover is initially disturbed. When the dust cover is provided with a tamper-evident sealing band, the use of a band on the lower edge of the pour spout closure for providing tamper-evidency may be eliminated.
摘要翻译：本发明通常提供一种带螺纹的防拆封闭件，其具有环形钩形凸缘，该环形钩状凸缘从附接到封盖体的底部边缘的防拆封带的内表面径向向内延伸。钩形凸缘可以是连续的或分段的，并且形成向上倾斜的表面，用于接合瓶颈上的密封凸缘。多个升高的区域从防盗显示带向上延伸，与封闭体的底部边缘成间隔开的关系。将显窃启带与封闭件的下边缘连接的环形凸缘连接的易碎元件可被配置成从防盗表带的这些升高区域以及未升高的区域延伸。可以使用配对棘轮的对来代替或与高架桥面组合，以减少放置在易碎元件上和/或在帽应用期间的应力。本发明的第二个优选实施例提供一种具有防窃启带的带螺纹的防拆封塑料封盖，其具有包含上述特征的防窃启带，用于基本上防漏的防篡改推拉可再密封倾倒口。本发明还可选地提供一种防尘盖，其在插入容器时包围推拉倾倒口封闭件。防尘罩可以可选地设置有防敏性密封带，其在初始将防尘罩安装到容器上时保持完整，并且当防尘罩最初被打扰时，防尘盖被破坏。当防尘盖设置有防窃启密封带时，可以消除倾倒口封闭口的下边缘处的带子用于提供防篡改性。
