Tamper-evident container closure with flip-top cap

A tamper-evident closure comprising

• a body adapted to mount onto a container formed to include an outlet opening into an interior region formed in the container,
• a cap configured to be mounted on the body in a closed position overlying the outlet and separated from the body in an opened position uncovering the outlet, and
• tamper-evident means coupled to the cap and to the body for breaking in response to movement of the cap relative to the body from the closed position toward the opened position to provide a tamper-evident signal visible to an observer that the cap has been moved relative to the body from the closed position toward the opened position, wherein the tamper-evident means includes
• at least one radially extending not S-shaped frangible connector arranged to interconnect the body and the cap and at least one S-shaped frangible strap, each S-shaped frangible strap having an inner portion coupled to the cap, an outer portion coupled to the body, and a serpentine portion arranged to interconnect companion inner and outer portions and wherein the cap is a flip-top cap and further comprising hinge means coupled to the body and to the flip-top cap for supporting the flip-top cap for movement relative to the body from the closed position to the opened position to break, in series, first all of the radially extending frangible connectors and then each of the S-shaped frangible straps during first time movement of the flip-top cap relative to the body from the closed position to the opened position to provide the tamper-evident signal.

• at least one radially extending not S-shaped frangible connector arranged to interconnect the body and the cap and
• at least one S-shaped frangible strap, each S-shaped frangible strap having an inner portion coupled to the cap, an outer portion coupled to the body, and a serpentine portion arranged to interconnect companion inner and outer portions and wherein the serpentine portion of each S-shaped frangible strap is arranged to lie in a horizontal plane that is orthogonal to a vertical central axis extending through the body and the cap when the cap is located in the closed position and to lie between and in spaced-apart relation to the body and the cap in the closed position of the cap.

• wherein the cap is a flip-top cap and further comprising hinge means coupled to the body and to the flip-top cap for supporting the flip-top cap for movement relative to the body from the closed position to the opened position to break the serpentine portion of the undulating frangible strap during first time movement of the flip-top cap relative to the body from the closed position to the opened position to provide the tamper-evident signal, and
• wherein the flip-top cap includes a side wall having a rearwardly facing rear portion coupled to the hinge means and an opposite forwardly facing front portion arranged to lie in close proximity to the body in the closed position of the cap, the side wall of the flip-top cap further includes a first concave portion arranged to lie between the front and rear portions and in spaced-apart relation to the body in the closed position of the cap to form a first strap-receiving space therebetween, and the first undulating frangible strap is arranged to lie unbroken in the first strap-receiving space coupled at an outer end thereof to the body and at an inner end thereof to the first concave portion of the side wall of the flip-top cap until first-time movement of the flip-top cap from the closed position to the opened position to provide the tamper-evident signal.
