Benefits of technology

[0004]A tamper-indicating package in accordance with one aspect of the present disclosure includes a container having a neck finish with at least one external thread segment, at least two angularly spaced sets of external ratchet teeth spaced from the thread segment and a circumferentially extending radial enlargement between the two sets of ratchet teeth. A closure includes a skirt with at least one internal thread segment engaging the external thread segment on the container neck finish, a tamper band frangibly connected to the skirt, and a

Problems solved by technology

However, it has been found that the tamper band of such a closure can ovalize into the areas between the sets of ratchet teeth on the container neck finish, resulting in uneven separation of the tamper band from the closure skirt.

Embodiment Construction

[0015]FIGS. 1-2 illustrate a package 20 in accordance with one exemplary embodiment of the present disclosure as including a closure 22 applied to the neck finish 24 of a container 26. Closure 22 includes a skirt 28 with at least one internal thread segment 30 engaged with at least one external thread segment 32 on container neck finish 24. (The term “thread segment” is used in its usual broad sense to include both single and multiple threads, and both continuous and discontinuous threads.) The bullet-nose geometry of neck finish 24 illustrated in FIGS. 1 and 5 (and the bullet-nose geometry of neck finish 54 in FIG. 9) is merely exemplary. Although closure 22 is illustrated in FIG. 1 as a multipiece closure, it will be recognized as the description unfolds that the principles of the present disclosure apply equally as well to one-piece closures.

[0016]A tamper band 34 is frangibly connected to skirt 28, such as by frangible leaders 36. Leaders 36 can be molded into closure 22 and / or ...

Abstract

A tamper-indicating package includes a container having a neck finish with at least one external thread segment, at least two angularly spaced sets of external ratchet teeth spaced from the thread segment and a circumferentially extending radial enlargement between the two sets of ratchet teeth. A closure includes a skirt with at least one internal thread segment engaging the external thread segment on the container neck finish, a tamper band frangibly connected to the skirt, and a circumferential array of internal engagement elements on the tamper band for engaging the ratchet teeth on the neck finish to prevent rotation of the tamper band with respect to the ratchet teeth and thereby sever the tamper band from the closure skirt upon first unthreading of the closure from the container neck finish. The circumferentially extending radial enlargement between the sets of ratchet teeth is slidably engaged by the engagement elements on the tamper band to prevent ovalization of the tamper band between the sets of ratchet teeth.

Description

[0001]The present disclosure relates to tamper-indicating closures and packages, and more particularly to a tamper-indicating package having a container with diametrically spaced sets of ratchet teeth on the neck finish and engagement elements on the tamper band of a closure applied to the container neck finish.BACKGROUND AND SUMMARY OF THE DISCLOSURE[0002]U.S. patent document 2005 / 0199574 discloses a tamper-indicating package that includes diametrically spaced sets of external ratchet teeth on the container neck finish. The closure has a tamper band frangibly connected to a closure skirt and a circumferential array of internal engagement elements in the form of flexible resilient wings on the tamper band. The wing-shaped engagement elements engage the ratchet teeth on the container neck finish to prevent rotation of the tamper band with respect to the neck finish so that the tamper band is at least partially severed from the closure skirt upon first removal of the closure from the ...
