Abstract: A tamper-resistant dispensing structure including a closure for selectively closing an opening in a wall forming a portion of a container. Retaining structure is provided for maintaining the closure in association with the wall and with a stopper portion thereof maintained suitably for accurate fit with the opening in the wall during a closing operation. A flange is provided on the container for controlling the lateral disposition of the closure on the wall. In one form of the closure, the container flange is turned to cause the distal end thereof to retain the periphery of the closure against the wall.

Abstract: A closure is provided for selectively closing an opening of a container, including a base element arranged to be affixed to a container adjacent an opening therein. In one embodiment, the closure is provided with tamper-evident film fixed to the base element, and a control element is pivotally movable relative to the base element between open and closed position. When the base element is affixed to the container, the tamper-evident film obstructs the container opening. When the control element pivots to the open position, the tamper-evident film is visible, and can be punctured or otherwise removed. According to another embodiment of the invention, a closure is provided for a container having a tamper-evident film secured thereto overlying the opening in a container.

Abstract: Closure for selectively closing an opening in a wall, including a base element arranged to be affixed to the wall adjacent the opening therein. In one form, the closure includes an insert having a through opening and defining a recess adjacent the through opening. The insert is urged sealingly against the wall about the wall opening thereof, with the through opening of the insert being aligned with the wall opening. A control element is provided having a connecting portion swingably mounting the control element to the base element, a stopper portion adapted to be received in the insert opening when the control element is pivoted to a first, closed position, and a presser portion adapted to be engaged by a user's fingertip to pivot the control element to withdraw the stopper portion from the insert opening and dispose the presser portion within the recess in a second, open position of the control element.
