Tamper evident flip top closure

A package comprising

• a container and
• a closure coupled to the container to control release of product therefrom, the closure including a closure body coupled to the container and formed to include a discharge aperture and a flip-top cap coupled to the closure body and configured to pivot relative to the closure body between a closed position blocking access to the discharge aperture and an opened position allowing access to the discharge aperture,
• wherein the closure body includes an outer body sidewall, an inner body sidewall spaced radially inward from the outer sidewall relative to a central axis of the closure body and having a retainer segment and a tab-locking segment spaced circumferentially from the retainer segment relative to the central axis, and a body top wall coupled to an upper end of both the outer body sidewall and the inner body sidewall and formed to include a tab-receiving aperture opening into a space located radially between the outer body sidewall and the tab-locking segment of the inner body sidewall,
• wherein the flip-top cap includes a cap sidewall, a cap top wall coupled to an upper end of the cap sidewall, and a retainer tab including a cap-lifting segment coupled to at least one of the cap sidewall and the cap top wall, a breakaway segment extending away from the cap-lifting segment and through the tab-receiving aperture when the flip-top cap is in the closed position, and a frangible border connecting the breakaway segment to at least one of the cap-lifting segment and the cap sidewall,
• wherein the flip-top cap is configured change from an unused, closed configuration in which the breakaway segment of the retainer tab is coupled to at least one of the cap-lifting segment and the cap sidewall by the frangible border, to a first-use, opened configuration in which the breakaway segment is separated from at least one of the cap-lifting segment and the cap sidewall after rotation of the flip-top cap about a cap pivot axis to provide tamper evidence,
• wherein the container includes a filler neck having external threads and both the tab-locking segment and the retainer segment of the inner body sidewall include internal threads that correspond to the external threads to install the closure on the filler neck, and
• wherein the tab-locking segment includes a segment wall, the internal threads, and a ramp coupled to an inner surface of the segment wall below the internal threads.

A closure configured to control release of product from a container, the closure comprising

• a closure body formed to include a discharge aperture and,
• a flip-top cap coupled to the closure body and configured to pivot relative to the closure body between a closed position blocking access to the discharge aperture and an opened position allowing access to the discharge aperture,
• wherein the closure body includes an outer body sidewall, an inner body sidewall spaced radially inward from the outer sidewall relative to a central axis of the closure body and having a retainer segment and a tab-locking segment spaced circumferentially from the retainer segment relative to the central axis, and a body top wall coupled to an upper end of both the outer body sidewall and the inner body sidewall and formed to include a tab-receiving aperture opening into a space positioned radially between the outer body sidewall and the tab-locking segment of the inner body sidewall,
• wherein the flip-top cap includes a cap sidewall, a cap top wall coupled to an upper end of the cap sidewall, and a retainer tab including a cap-lifting segment coupled to at least one of the cap sidewall and the cap top wall, a breakaway segment extending away from the cap-lifting segment and through the tab-receiving aperture when the flip-top cap is in the closed position, and a frangible border connecting the breakaway segment to at least one of the cap-lifting segment and the cap sidewall,
• wherein the flip-top cap is configured change from an unused, closed configuration in which the breakaway segment of the retainer tab is coupled to at least one of the cap-lifting segment and the cap sidewall by the frangible border, to a first-use, opened configuration in which the breakaway segment is separated from at least one of the cap-lifting segment and the cap sidewall after rotation of the flip-top cap about a cap pivot axis to provide tamper evidence, and
• wherein the closure is configured to change from a pre-installation configuration, in which the breakaway segment of the retainer tab is received in the tab-receiving aperture when the flip-top cap is in the closed position and the closure is separated from a container, and a container-installation configuration, in which the tab-locking segment of the inner body sidewall is pushed radially outwardly towards the outer body sidewall when the closure is screwed onto a container so that the breakaway segment of the retainer tab remains between the outer body sidewall and the inner body sidewall when the flip-top cap is in the closed position and the opened position.

A closure configured to control release of product from a container, the closure comprising

• a closure body formed to include a discharge aperture and,
• a flip-top cap coupled to the closure body and configured to pivot relative to the closure body between a closed position blocking access to the discharge aperture and an opened position allowing access to the discharge aperture,
• wherein the closure body includes an outer body sidewall, an inner body sidewall spaced radially inward from the outer sidewall relative to a central axis of the closure body and having a retainer segment and a tab-locking segment spaced circumferentially from the retainer segment relative to the central axis, and a body top wall coupled to an upper end of both the outer body sidewall and the inner body sidewall and formed to include a tab-receiving aperture opening into a space positioned radially between the outer body sidewall and the tab-locking segment of the inner body sidewall,
• wherein the flip-top cap includes a cap sidewall, a cap top wall coupled to an upper end of the cap sidewall, and a retainer tab including a cap-lifting segment coupled to at least one of the cap sidewall and the cap top wall, a breakaway segment extending away from the cap-lifting segment and through the tab-receiving aperture when the flip-top cap is in the closed position, and a frangible border connecting the breakaway segment to at least one of the cap-lifting segment and the cap sidewall,
• wherein the flip-top cap is configured change from an unused, closed configuration in which the breakaway segment of the retainer tab is coupled to at least one of the cap-lifting segment and the cap sidewall by the frangible border, to a first-use, opened configuration in which the breakaway segment is separated from at least one of the cap-lifting segment and the cap sidewall after rotation of the flip-top cap about a cap pivot axis to provide tamper evidence,
• wherein both the tab-locking segment and the retainer segment of the inner body sidewall include internal threads that correspond to external threads of a container to install the closure on the container, and
• wherein the tab-locking segment includes a segment wall, the internal threads, and a ramp coupled to an inner surface of the segment wall below the internal threads.
