Abstract

A screw cap, especially one made of plastic, for closing a bottle or the like, with a cylindrical threaded section having a female thread to be screwed on the male thread of a bottle-neck, connected to the security ring via break points, on which there are inwardly-directed catches to engage with an outer collar on a bottle-neck. The free edge (14) of the cylindrical part (3) has at least one axial projection (15) which engages positively in a recess (17) in the opposite edge of the security ring (11) in the circumferential direction and releasably in the axial direction. This positive toothing ensures that, when the screw cap is first screwed on the neck of a bottle, the webs (10) are not sheared off by increased torques which can be applied if the catches run on the outer collar of the bottle-neck under tension.

Description

`:~ENT BY:BANNER & WITCOFF, LTD.; 9-25-96 ; 11:09 ;BANNER & WITCOFF,LTD~ 416 368 1645;# 3/ 7 " 21 865~4 A Screw Cap, s~,ecifi~,~lly co.l,l,,;scd of phstic, for closing a bonle or the like.

The i~ tion rclate~ to a screw cap of the lype ;~.~lir~t~l in the preamble of daim 1- for dosing a bottle or the like.

DE 41 08 453 Al reveals a scre v cap ofthe respeGtive type, ~ the inwardh~r ~ .,d catches are hook shapcd in order that, wben the ~crew cap is first s~.:ed on to ~e outer ~reat of a bottle neck, the catches ~nap on behind a circumf~e"t;al outer collar arranged on the bottle neck for s~u,it~ poses. When s~re..i,~ the screw cap off the bottle, the hook shaped catches keep the sec~ ring back from the outer collar on the bot~e neclc, so that the brealc points formed of thin webs between the sec~ty ling and the cylindrical part ofthe screw cap bre~k o*`, and thus the se~ nng remains behind on the bottle ~eck.
It i9 thus assured tllat the bottle has not previously been opened, since when the cap is unsc~red the security ring is held ba~k on the bottle neck in a lo.ose manner. It i~ thus ea~y for anyone to ~ecG~ ~Jhetl~r the bottle has already been opencd ODCe.

A disadvan~age to ~is known screw cap is that a relatively great torque is req~.~d when the hook shaped catches on the security ring are moved ov~ the outer collar on the bot~e neck. ks a re~ult ofthis i~ ,ased torque there is a risk that tbe break points formed of thin webs between the safety ring and the c3rlindrical part of ~e scrcw cap will shear of E; even as the cap is scle~.ed Oll, so that the security ring then rests loosely on the neclc ofthe bottle, just as in dle case where the bottle has been opened for the first time and has then been closed again. The filct ~at the co~ne~.~, of the bottle have never been opened is tllc~ ie not ecog.~ble or guaranteed.

The hJ~ tion has the task of devising a screw cap of the ~ c type~ whereby the danger of sheanng off the break points betwee~ ~e cylin~ical part of ~he scre v cap and the ~wil~ ~i~ is deerc~d du~ing the initial SCJ~,..h4; on ofthe cap.

SENT BY:BANNER & WITCOFF, LTD.; 9-25-56 ; 11:10 ;BANNER & WITCOFF,LTD~ 416 368 1645;# 4~ 7 21 ~365~34 The basic task ofthe invention is accomplished by thc illustrated teaching of the chara~,t~;.,t;c portion of daim 1.

The basic Col cept of the teaching consists of co~ ~c~-tin~ the c~ ~ ic~l part of ~he screw cap and the s~u~it~r ring in a finn locldng manner in the circumr~l~ ~' Ji,.,~ Lorl, bul p~ its removal in the direction ofthe threading. By positi~ely en~ the opposing edges of ~e cylindrical par~ and the security ring, great tor~ues can be t~ .;thout tbe Op~Ot ~ mo~w..ent ofthc two parts, so that there is no danger that ~e brealc points that connect tbe sccu.ity ring with the cylindrical part of the saew cap i~ the original condition can be sbeared or torn off.

The pr~ nn and the recess are e~pedient~ at nght angles, ..hc~ a plurality of p~ tinr^ and ,.~u.ss~ rc e,.p~r tl~ pn,~;~ed, prefe~ably engaging with each otber in meander sha~ed manner. The webs can basically be locatet at ar~r desired posi~on~ at is, for example, where no ~ je~l;c.nc and ~ces3es enga~e each other. Expedi~dy, the break points are located t.,h.~:ll cu~ y j~ pos~d surfaces of proje~ nQ ~nd ~e~s~s. The brealc points can also be fonned by means of webs arranged ~ the ~ j~io~
cce~ s~ The too~hing expediently extends over the entire ~w l.rc~e.

~ig. 1 shows a~n axial se~ion th~ou~h an exemplified ~ -~bo ~ of a screw cap according to the inven~on, tog IhFr with the a~c~ ?~ u~ neck ofthe botde.

Fig. 2 is an enlarged vie~v Il in ~igure 1 Figure 1 show~ a screw cap 1 co~ .;3ed of plastic 9~CC ~diug to ~
e~nbo~ of ehe im.c,llion. It ~dtules a bottom 2 and a cylindrical threaded part 3, witb an inner thread 4 to be s~ d onto an outer thread 5 of a bottle neck 6, which i`3 Ollly partially illustrated. A gasket 8 is located between the boltom 2 and a f~ce edge 7 ofthe bottle neck 6.

SENT BY:BANNER & WITCOFF, LTD.; 9-25-96 ; 11:11 ;BANNER & WITCOFF,LTD~ 416 368 1645;# 5~ 7 21 865(~4 A lower edge 9 of the cylin-~ir~ palt 3 i9 CQn~eCted tO a ~il~f ring 11 by means of webs 10, s~id sec~uity ring featuring inner Gatches 12.which engage an outer collar 13 on the bot~e ne~ 6 in thc ilhi"l.a,~ state where the c~p is to be s~ .cd on.

Figure 2 shows a view lI inFigure 1. Tt shows that a lower edge 14 of the cylindrical part 3 features ~ ~ iGUI~r projecdon~ 13 which engage fiush with the c~ ~Gn~ing rc~cs~3 16 in the seGur~ty nng l l. An h ediste spac~e l? is fonned ~.,h.~l~ ~e p~uje.,lio~ls 15 and the bottom oftbe .~ess~ t 1, ..h~. the webs 10 ~Nhich hold the se~ity ring 11 onto the cylinJ~ l part are allanged.

Durin~ the initial scre~,v on of a screw cap 1 au~r~lg to Figure 1 the ~>~ o;e~ ns 1 illust~ed in Figure 2 provide that the security nng 11 is taken along ~ithoul ar~r relative o~pOYI ~ move~ , even when thc torque is high, which is the case wh~n the catches 12 run onto the oute~ collar 13 and move over it under tension. The thin webslO are lh prevented from shearing or tealing off during tbe process of 5~ 8 on the cap.

The pr~ectionC 15 need only abut the opposing edges ofthe .,cc~s 16 in the dire~tion of sc e~u~g on thc cap, but not necessarily in the opposite direction, the removal dir~lioh At that pOS;1;~ for exunplein the uea ~el..ecn surfaces 18, 19 and sur~ces20, 21,as ;--~;r-t~ by dot-dash lines, break points 22, 23, ;~ ~ by shading, can then be _.o_d, serving the same p~l,o~c as the webs 10 that fonn ~e break points, and these Ivebs can then be elinunated.
