referring to fig1 and 2 , a one - piece closure 10 is molded of plastic , such as polypropylene , and comprises a base wall 11 and a peripheral skirt 12 . the skirt and base wall are joined at an upper edge radius 13 . inside skirt 12 are means such as internal threads 14 which are adapted to interengage corresponding means on a container 15 such as threads 16 along the circular upper finish 17 of container 15 . a tamper - indicating band portion 18 is joined to the lower edge of the skirt 12 by a rupturable means , one form being illustrated on fig1 and 4 as an annular weakening provided by score line 26 cut to partial depth through the circumference , or cut alternately partial depth spans and full cut dept spans of the material of the upper part of band portion 18 and just below the lower edge of skirt 12 . in this fashion , the band 18 is attached to the closure by a frangible means along a weakened line . along the interior of band portion 18 there is formed series of inwardly facing projections , herein called &# 34 ; beads &# 34 ;, 20 and arranged around the interior circumference in plural tiers or levels . the beads 20 are arranged in a series each at a different level in the band . one such series is shown on fig3 indicated as 20a , 20b and 20c . the uppermost bead 20a repeats in the next adjacent series , and so forth , and the last or lowermost bead 20c lies adjacent an uppermost bead 20a . the beads 20a - 20c of each series is disposed along a pitch line that is inclined by angle &# 34 ; p &# 34 ; from horizontal radial line on fig3 . the angle &# 34 ; p &# 34 ; will be the same as the pitch of threads of the container finish . as an example , the thread pitch angle of container threads is 20 ° from horizontal angled in the direction of rotation of the closure for applying it onto the container finish . as seen on fig4 this pitch angle &# 34 ; p &# 34 ; is provided in the upper surface 21 of the bead 20 . the compound surfaces below surface 21 extend into the wall of band and provide a cammed surface 22 that is sloped downwardly from surface 21 to meet the band wall . this compound surface 22 , as it meets the surface of the threads 14 of the container , is at a much steeper angle with the horizontal . as the closure is being removed from the container , the uppermost beads 20a come into contact with a circumferentially disposed lower transfer bead 23 located lowermost on the bottle finish . bead 23 provides a locking ring on the container for the tamper - indicating band of the closure . as the closure is unscrewed from the full &# 34 ; on &# 34 ; position , fig5 the uppermost beads 20a each engage the lower transfer bead 23 at its undersurface . the gripping of beads 20a on the transfer bead of the container halt the lifting of the band 18 of closure 10 . the annular score line of weakening , shown in the embodiment of fig1 - 3 and 5 , will cause a rupture between band 18 and skirt 12 along score line separating the band and skirt . the closure 10 will be unscrewed from container 15 and band 18 will be retained on the neck 17 below the transfer bead 23 . beads 20 are solid which will prevent collapsing them against the band by someone tampering with the package . the staggered tier arrangement of the beads in sets distributed circumferentially on band 12 increase the difficulty to defeat the tamper - indicating feature of the invention . the arrangement of beads 20 prevents the &# 34 ; tiring &# 34 ; of the band past the circular bead on the bottle by inserting a shim - like device between the band and container for successively displacing the beads past the retaining surface of the container . the &# 34 ; tiring &# 34 ; technique is used on some tamper - indicating closures to defeat them ; that , is , remove the closure without separating the band from the closure . as shown on the drawings , four sets of beads 20 are employed totaling 12 of beads 20 around the inside of band 18 . in this arrangement , the beads are angularly arranged 30 ° apart , center to center . the projecting beads may vary in number and in the number in each tier or set . for the ease of application of the closure , equal angular spacing of the beads around the band is preferred . the invention provides an advantage in capping the container . in most of the present tamper - indicating closures in use the capper must utilize an axial top pressure along with the rotary movement to apply the closure to a threaded container . the top pressure is necessary to force the tamper band devices or projections past the threads . in the present invention , the sustained top pressure by the capping head is no longer necessary because the projecting beads lie along a thread pitch line comparable with the container threads . in essence , beads 20 are arranged to thread themselves by their surface 21 riding under container threads 16 until they pass the end of the thread . at this point , the threads 14 in the closure skirt are engaged with container threads 16 and drive the closure to the full &# 34 ; on &# 34 ; position ( see fig5 ). in the downward rotary movement of the closure , the lower surface 22 of the beads 20 ride over the circumferential bead or beads on the container ( see fig8 - 10 ). the preferred arrangement shown in the present disclosure provides two such annular beads on the container . the lowermost annular bead 23 is spaced below uppermost annular bead 24 along the container neck and below threads 16 thereon . the annular space between the circumferential beads 23 and 24 provides a smooth transition groove 25 , the base of groove 25 being slightly greater in diameter than the container neck below bead 23 . in practice , beads 23 and 24 on the container serve as transfer beads in molding the container ; that is , the neck molds include the beads and the latter are used in transferring the container in the container manufacturing process . the container finish 17 should herein include the two transfer beads 23 and 24 for an advantage in providing a tamper - indicating package . should one level of the beads 20 on the closure band be manipulated above the lower container bead 23 , it will become isolated below bead 24 and is virtually assured against manipulation intact past the uppermost bead 24 . as is illustrated on fig8 - 10 , threads 14 of the closure move along threads 16 of the container and the lower beads 20c on band 18 each engage upper locking ring 24 . the lower surface 22 of the beads ride over the surface of ring 24 and below it . in succession , mid - level beads 20b do the same ; and finally upper beads 20a follow suit . the sequence is repeated at the lower locking ring 23 on the container . where the closure 10 is fully applied , beads 20 are all located below ring 23 , as shown on fig5 and 6 . in this full &# 34 ; on &# 34 ; position the gasket 28 in the top wall 11 of the closure seals against rim 29 of the container . the apex 30 of rim 29 forces itself into the yieldable gasket material and make a full annular seal against leakage of product . in the embodiment of fig5 the inside wall of the closure skirt 12 and band 18 is continuous and straight in an axial direction . the weakening line 26 is a v - shaped groove formed in the outside of the band wall . this groove is formed after the closure is molded by known technique using either continuous cutting wheel or serated cutting wheel . as the sealed closure is unscrewed on the container threads , the upper level of beads 20a raise to engage the under - surface of locking ring 23 . should band 18 distend itself , the other levels of beads 20b and 20c will similarly engage ring 23 . this will hold band 12 from further axial movement and the stress imparted by unscrewing the closure further causes the band wall to break at the line of weakening at the annular groove 26 . a second type of rupturable connecting means is disclosed on fig6 . the tamper - indicating band of this embodiment is outwardly disposed and offset slightly from the interior of the skirt wall such that an annular series of circumferentially spaced - apart bridges 32 are formed between the lower edge 12a of the skirt and the band 18 . the bridges 32 are molded as axial columns or posts of thin section and are rupturable . as shown on fig8 - 10 , bridges 23 flex outwardly when the closure is applied and permit the several beads 20 to move over locking rings 23 and 24 on the container . in the opposite direction as the closure is unscrewed from the container , the bridges fail in tension and torsion as the beads 20 engage under the container &# 39 ; s locking rings . another embodiment of the invention is shown on fig7 in which molded bridges 32 are integrally formed with a thickened band 33 . there is a step 34 from each of the bridges 32 reaching outwardly to the upper end of band 33 thicker in cross - section . this band includes a lower annular section 34 that is substantially thicker than the wall of band 33 and is continuous circumferentially . the thick circular lower section 34 at the bottom of the band will assist initial capping of the closure on the container . the extra material also offers a heat shrink option to the bottler . applying heat locally to the band section 34 will shrink it circumferentially adding further tamper - indicating assurance in the package . the invention provides for progressively engaging beadlike projections of the closure tamper band with one or more annularly disposed locking rings on the neck finish of the container as the closure is unscrewed . as more beads come into contact with the container the band is separated from the closure along its weakened line leaving the band on the container as evidence it has been opened . the band inside diameter is greater than the exterior diameter of the container neck below the locking ring . the band will drop when severed or separated from the closure skirt and is not readily matched up and held in place when the closure is reapplied . while the container illustrated is a glass container , it should be apparent the principles of this invention could be used with a plastic container or container of another material . the foregoing description is by way of example and constitutes a teaching of the best mode known for applying the principles of the invention . it is not intended to limit the scope of the invention to any extent greater than that set forth in the appended claims .
