发明名称 Tamper evident container closure
摘要 A tamper evident container closure has a skirt for permanent attachment to the mouth end of a container and a closure crown supported by the skirt. A cover on the closure is displaceable for exposing a well on the closure crown normally closed by the closure. The well has a floor which may be part of a crown panel of the container closure and the well floor has a dispensing opening therein. A rip-out tamper evident element is fixed in closing relation to the opening and requires destructive removal for dispensing access to the opening. A digitally manipulatable handle attached to the element is confined within the well in the closed condition of the cover and is accessible when the cover is displaced from the well for digital manipulation of the handle for forcibly destructively displacing the element from the opening. The portion of the cover over the well may have a sealing surface engageable about the well in the closed position of the cover.
