Low application torque, tamper evident plastic closure and container system with enhanced visual tamper evidency

A closure and container system, comprising:

• a container including:
• a receptacle,
• a neck extending from the receptacle,
• a closure-engaging thread segment of a first helical orientation, and
• a plurality of circumferentially spaced apart protrusions protruding radially outward from the neck of the container, the plurality of spaced apart protrusions forming two or more repeating helical protrusion patterns that each have a common elevation relative to an opening of the container and a composite orientation that is helically opposite that of the closure-engaging thread segment;
• and
• a closure including:
• a cap portion,
• a closure thread segment provided on said cap portion to engage the closure- engaging thread segment, and
• a frangible tamper-evident band portion such that when the closure is rotated off of the neck of the container, the frangible tamper-evident band portion engages at least a portion of the spaced apart protrusions to separate the frangible tamper-evident band portion from the cap portion of the closure.

A container for use with a closure having a closure thread segment and a frangible tamper-evident band portion, said container comprising:

• a receptacle;
• a neck extending from the receptacle;
• a closure-engaging thread segment that at least partially helically encircles the neck for engaging the closure thread segment of the closure;
• and
• two or more circumferentially spaced apart band-engaging thread segments that partially helically -encircle the neck at a same elevation relative to an opening of the container in an orientation opposite the closure-engaging thread segment, for engaging the frangible tamper-evident band portion, and for separating the frangible tamper-evident band portion from the closure when the closure is rotated off of the neck.

A container for use with a closure having a closure thread segment and a frangible tamper-evident band portion, said container comprising:

• a receptacle;
• a neck extending from the receptacle;
• a closure-engaging thread segment that at least partially helically encircles the neck for engaging the closure thread segment of the closure;
• and
• two or more band-engaging thread segments that partially helically encircle the neck at a common elevation relative to an opening of the container in an orientation opposite the closure-engaging thread segment, for engaging the frangible tamper-evident band portion, and for separating the frangible tamper-evident band portion from the closure when the closure is rotated off of the neck, wherein the two or more band engaging thread segments are circumferentially spaced apart and each partially encircles the neck in one or more substantially uniform helical patterns and wherein a plurality of helical lines helically encircle the neck of the container and define a respective helical pattern such that corresponding ones of the band-engaging thread segments are positioned along a respective one of the helical lines.

A closure and container system, comprising:

• a container including:
• a receptacle,
• a neck extending from the receptacle,
• a closure-engaging thread segment that at least partially helically encircles the neck, and
• two or more circumferentially spaced apart band-engaging thread segments, helically opposite that of the closure-engaging thread segment having a same elevation relative to an opening of the container;
• and
• a closure including:
• a cap portion,
• a closure thread segment provided on said cap portion to engage the closure-engaging thread segment, and
• a frangible tamper-evident band portion coupled to the cap portion, and having a band and at least one tab directed inwardly and upwardly with respect to the band and coupled therewith, for engaging the two or more band-engaging thread segments of the neck of the container,
• wherein the two or more band-engaging thread segments separate the frangible tamper- evident band portion from the cap portion when the closure is rotated off of the neck.

A container for use with a closure having a closure thread segment and a frangible tamper-evident band portion, said container comprising:

• a receptacle;
• a neck extending from the receptacle;
• a closure-engaging thread segment that at least partially helically encircles the neck for engaging the closure thread segment of the closure;
• and
• at least two band-engaging thread segments that partially helically encircle the neck in repeating patterns at a common elevation relative to an opening of the container in an orientation opposite the closure-engaging thread segment, for engaging the frangible tamper-evident band portion, and for separating the frangible tamper-evident band portion from the closure when the closure is rotated off of the neck, wherein the at least one band-engaging thread segment is n band-engaging thread segments such that n-1 gaps are formed between circumferentially adjacent band-engaging thread segments, where n is an integer number two or greater.

A container for use with a closure having a closure thread segment and a frangible tamper-evident band portion, said container comprising:

• a receptacle;
• a neck extending from the receptacle;
• a closure-engaging thread segment that at least partially helically encircles the neck for engaging the closure thread segment of the closure;
• and
• two or more band-engaging thread segments that are spaced apart, have beginning positions of respective ones of the spaced apart band-engaging thread segments at a same elevation relative to an opening of the container, and at least partially helically encircle the neck in an orientation opposite the closure-engaging thread segment, for engaging the frangible tamper-evident band portion, and for separating the frangible tamper-evident band portion from the closure when the closure is rotated off of the neck,
• wherein a plurality of helical lines helically encircle the neck of the container and define a respective helical pattern such that corresponding ones of the band-engaging thread segments are positioned along a respective one of the helical lines.
