A tamper-evident closure () is provided for a container. In one particular embodiment, the closure () has a body () and a hinged lid (), and has the following additional features as next described. A tamper-indicating tab () is connected to the lid () by a frangible junction (). A pressing member () is connected to the closure body () for movement from an initial unactuated configuration and to an inwardly deformed, actuated configuration. A post () is provided on either the pressing member () or tab (), and a slot () is defined in the other of the pressing member () and tab (), wherein the slot () non-releasably receives the post () when the lid () is first closed. The closure body () also has an inwardly located retention wall () defining an aperture (). When the pressing member () is pressed inwardly, the frangible junction () is broken to allow the lid () to be lifted, and an end portion of the post () is non-releasably received in the retention wall aperture ().

Closure with tamper-evident feature

A closure that can be threadingly screwed onto an associated container includes a body having a thread form for engaging a thread form on the container. The body has a wall with projecting hook-like ribs. By the provision of the hook-like ribs, the closure exhibits an enhanced capability for being gripped by the rollers of an automatic capping machine, to accommodate a relatively high torque installation without slipping in an automatic capping machine.

Closure for high torque installation on a container

A toggle-action dispensing closure for a container is provided for manipulation between a closed, non-dispensing orientation and an open, dispensing orientation. The closure includes an actuator pivotally mounted along a tilting axis on a body secured to the container. The actuator is tiltable by applying force to the actuator on one side of the tilting axis so as to move the actuator from a non-dispensing position to a dispensing position. The actuator includes a flange having an engagable surface. The closure body includes an annular wall in which the actuator is received, and the annular wall includes an inwardly projecting interference member which underlies the actuator engagable surface and prevents tilting of the actuator unless a sufficient predetermined, initial opening force is exerted on the actuator to cause permanent, plastic deformation of the engagable surface is and/or interference member. Thereafter, the actuator can be tilted to the open dispensing position a second or subsequent times in response to subjecting the actuator to a force less than the predetermined, initial opening force.

A closure structure is provided for a container that has an opening to the container interior. The closure structure includes a closure base for extending around the container opening. A lid is provided on the closure base and is connected to the base by a hinge web. The hinge web has a first end connected to the closure base, a second end connected to the lid, and two sides which each extends between the first and second ends. A frangible, reduced-thickness section of material initially connects the lid to the closure base and initially connects both of the hinge web sides to the closure base or to the lid for initially holding the lid sealed closed at a tamper-evident, first closed position and for subsequently accommodating movement of the lid relative to the first closed position to break the frangible connection and become selectively located at one of the following positions: (1) a second closed position inwardly of the first closed position, and (2) an open position outwardly of both the first closed position and second closed position.

One-piece tamper-evident closure system with a resealable, hinged lid

A removal torque-resistant closure and container assembly is provided with the container having a thread extending around the opening. The closure includes a thread for engaging the container thread. The container includes a projection that extends from the thread root between two adjacent thread crests on the container and that defines an outer edge for temporarily deforming the closure thread during relative rotational movement of the container and closure when the container and closure are screwed together. Upon termination of the screwing action, the container projection edge is engaged with a deformed region of the closure thread so as to resist closure removal by unscrewing.
