A container for use with a closure is provided, and includes a receptacle, a neck extending therefrom, a closure-engaging thread segment arranged on the neck of the container to engage the closure thread segment arranged on the closure, and a plurality of spaced apart protrusions protruding radially
A container for use with a closure is provided, and includes a receptacle, a neck extending therefrom, a closure-engaging thread segment arranged on the neck of the container to engage the closure thread segment arranged on the closure, and a plurality of spaced apart protrusions protruding radially toward the closure from the neck of the container, the plurality of spaced apart protrusions forming a protrusion pattern that has a composite orientation that is helically opposite that of the closure-engaging thread segment to engage and to separate the frangible tamper-evident band portion from the closure when the closure is rotated off of the neck. With this structure, the closure and container system provides an improved anti-backoff, tamper evident closure and container system that reduces torque used to initially apply the closure to the container and improves reliably by reducing stress on the component parts, while desirably preventing backoff from occurring.

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. 3. 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. 4. The container of claim 3, wherein a visual gap is formed between the separated frangible tamper-evident band portion and the closure when the closure is fully rotated back on to the neck of the container. 5. The container of claim 3, wherein the closure-engaging thread segment is oriented right handed. 6. The container of claim 3, wherein the orientation of the two or more band-engaging thread segment is left-handed. 7. The container of claim 3, wherein the closure thread segment helically encircles the neck at least once. 8. The container of claim 3, wherein each band-engaging thread segment is positioned at an elevation that is between those of the closure-engaging thread segment and the receptacle. 9. The container of claim 3, wherein the container is made of plastic, glass or metal. 10. The container of claim 3, wherein each band engaging thread segment partially encircle the neck in one or more helical patterns. 11. The container of claim 10, wherein each of the helical patterns is a substantially common helical pattern. 12. 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. 13. The container of claim 12, wherein beginning positions of the spaced apart band-engaging thread segments are at a substantially common elevation relative to an opening of the container. 14. The container of claim 12, wherein ending positions of the spaced apart band-engaging thread segments are at a substantially common elevation relative to an opening of the container. 15. The container of claim 3, wherein: the frangible tamper-evident band portion comprises a band and a plurality of flexible tabs coupled thereto; and the at least one band-engaging thread segment is profiled such that at least a portion of the plurality of flexible tabs of the frangible tamper-evident band portion are folded back while the closure is rotated on the neck. 16. 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. 17.
