Thi-~ invention relate~ to a one piece pla~tic closure ~or fastening on a container comprising a lower part with a top ~urface in which a pouring opening is di~posed, a cap pivotably conn~cted thereto by a hinge sha~t, and a ~ecurity element connected i~ one piece to the olo~ure.
Plastic closures o~ the type mentioned above are known in many embodiment~. See, ~or example, U.S. ~etters Patent 3,441,1~1 and 4,487,324. A~ a rule, plastic alosures with a lower part and a cap pivotably connec~ed the:reto by a hinge sha~t alway~ employ ~ecurity bands which mu t be removed prior to the initial opening movement.

A similar plast~c closure i~ al~o taught by US
Letters Patent 4,696,408. Here, too, it i~ ~irst neaes~ary to tear of~ a ~ecurity band be~ore the closure can be opened. In contxa~t to the ~olution ln aacordance with the '3~ patent, this ~ecurlty band doa~ not op~ra e primarily by a positive ~it which ~ake~ the inltial opening impo~ible prior to the removal o~ the secur~ty ~and, but rather the security band mak~s it impo~slble to grip the cap as long a~
the ~ecurity band i~ still di~po~ed on th~ closure.
In aontrast to ~crew alosures having a ~curity ring at one end whlch i8 aonnect~d to an annular wall o~ the ~cxew cap by predeterminad break point~ and which ~ngage the back o~ an annular bead on the bottl~ne~k, it i~ n~ce~sary in connection with all Xnown pla~tlc closur~s havlng a lower part with a top surface in which a pouring opening i~
disposed and having a cap pivotably connected thereto by a hinge ~ha~t to perform an addit~onal manipulative ~tep prior to the initial opening mo~ement.
Manufacture o~ a one-piece pla3tia closure a~
described above, having a ~ec~rity band, i8 extremely problematlcal. For one thing, the ~ecurity bands often tear whe~ b~ing removed ~rom the in~Qation mold becau e they get caught in th~ cavitie~ o~ the in~ection mold. In addition~
the long and thin 6eaurity band~ have a tQndenay to de~or~, a~ a re~ult o~ which initial clo~lng i~ either made impossible or the ~ecurity band tear~ at ~o~ o~ the predetermined break points during initial closing. Also, pla tia closure~ w~th a security band ar~ ~ot e~thetically plea~ing. Although guaranteed ~ecura clo~ure~ are being dcmanded by the ~05m~tic~ ~dust~y~ th~ known guararlteed F~229 3 . .la!m/1 ~3~
s~ure closures with a eeaurity band have not been ~ucc:essful .
It has al~o be~n 3hown that ~any u~;ar~3 ~3tlll ~o not under~tand the function of securit~y bands and try unsuccess~ully to open the cloeure without re~ovinq the security band. For this reason, such closures are ~till wrongly torn orf ox unsarewed~

Acc:ordingly, it is an ob~ect oiE this invention to provid~ a one~piece plastic clo~ure a~ previously de~;~ribed with a ~ecurity elLement wh~ ch does not require an aclditional ~anipulation prior to initial op~ning. It is a further obiect o~ this invention to provide a one~-plece dOE~Ure whiah overcomea the above-cited difiadvantage~.
The~e ob~ ect~ are aktain~d by a one-piece plastic:

The closure lO has a low~r part 11 and a cap 12 connec~ed ~o the lower part by a hinge sha~t 13, The h~nge shaft 13 i3 pre~erably constituted as a ~ilm hlngen How~ver other hinge sha~ts which are ~ovable, ~uch a~ strip~, can also be used.

The ~ecurity element 21 has a sealing ~ur~ace in the ~hape o~ a small plate 23, on the undsr~lde o~ which a bar 2fl i8 iEorm~d. The lower end of the bar 24 i8 provided with a positiLvQ loaking mean~ 25 in the form o~ a hook or a protru~ion~ In the exemplary embodiment ~hown, the top of the small plate 23 constituting the seal is ~lu~h with the top o~ the top ~ur~ac~ 1~ o~ the cap 12. A rec~ss 26 i~ ~ormed in the top sur~aca 1~ of the lower part 11, which reces~ 26 is located undsrn2ath the small plate 23 and through which the bar 24 extends below the top surface 16 and a8 ~ar as below the ~a~tening bead 3 on the containar neck Z. In thi~ way, the bar 2~L extends into the ~ree ~pace F. It i8 obviou~ that the lower part 11 mu~t be sealed with re8pQCt to the ~onta~ner n~ck 2, ~or which purpose an annular wall 27 ~ealingly extending into th~ container neck 2 and surrounding the pouring op~ning 17 i~ provided on the under~ide o~ the top sur~ace 16.

The closure in accordance with one embodiment o~
thi~ invention ls shown in the ~tat~ o~ use in Fig. 2. ~he clo6ur~ attain~ thi~ ~tate by an initial openlng ~ove~ent~
This g~ner~l way o~ expresslng th$~ i~ ba~ed on the fact that the security element ~ i3 cha~ged ~rom a 5~cured state to a st~te o~ use independ~ntly o~ the type of openin~. In the normal ca~e, the user would open the cap 12 by pivoting it around the pivot ~ha~t 130 ~n thi~ ca~e, the tcp sur~ace 19 ~P the cap 12 moves upward~ with re~pect to ths low~r F-~29 9 l~DIf~

part 11 or the c:ontainer neck a. In thi~ case, the po~itive locking means 25 now engage~ the lower end o:~ the bar ~4 at the ~a~;tening bead 3 of the con~ainer neck 2. With the continuing operling move~ent, the predete~ined break points 22 tear and the ~ecurity element 21 fall~ downward, becau~e it i~ no longer held in th~ cap 12. T:his is po~silbls due to ~rae space F havlng su:Efiaient ~pace ~Qr the bar 24. It can therefore be observed through the ope~irlg 28 in the top sur~ace 19 o~ the cap, which i~ now eacpc3sed, that khe closure 10 i~ no longer in the ~ecured position.
An opening movement of the entire closure 10 has the same ef~ect. If lthe clo~ure 10 is designed aæ a Rorew ClQ8Url3, it iB turned with re~p~3ct to th~ contain~r 1 or the container neck 2 during the initial opening moven ent o~ the entire closure 10. During the initial opening ~nove.m~nt, the po~itive locking means 25 on the bar 24 initially glides only along the lower edge oP the iEa~tening 3: e~ad 3, wheraupon the positive lock:Lng means 25 again engage~ the bank of the ~a;~ening bead in the course o~E the ub~e: [uent upwar~
vertical ~ovement o~ he closur~ 10 and tha predetermined br~aak points 22 tear. H~:re, too, the entire ~eaurity el~ment 21 fall~ into a low~r position and frees a hole 28 in the top surface 19 o:e th2 cap lZ.
After initial opening, becau~s the ~ecurity element 21 has per~ormed it~; actual ~unc1:ion, it can be easily removed. However, i~ the recess 26 iG de~igned in ~uch a way that it i~ possible to mainta~n the mall plate 23, which in the secured ætate i~ u~ed as a ~eal, in a po~itiv~ly- a3ld/or ~orced locked ~anner in it, the se¢urlty ele~ent now take~ on an e~thetia task in that it cc)Yer~ the :-rece~s 26 ~l~gantly. In the simpl~t c~e, lt i~ po~3stble to push the ~ecurity element 21 manually into th~3 recess 2 F-229 10 la~/l 2 ~
aft~r ~he cap 12 i~ inltially open~d. Howev~r, b~cau~e many users do not arrive at thls concluE~ion, a ba~le 30, ~or example in ~h~ ~;hape o~ a ~pring arm0 may be provlded on the under~ide of the top ~ur~ace 19 o:f kh~ cap 12. A~ a r~sult, during the course of the initial opening moYement of the cap 12, thig3 baffle 30 will automatically 'pre~ on the E;~all plate 23 during the ~ubses~uent closing proce~ and pres~ it into the recess 2 6 .
The em~odiment herein de~crihed ~ there~ore ab~olutely fool-proo~ in it~ ~unction and Dake~ a wrong manipulation impo sibleO Because of th~ functlonal co~meckion between the seaurity ele:ment 21 and tha container 1 provided in this con~tructiorl, it 1~ not possibl~ to ~parate the ~ntire clolurli3 lo ~rom the corltainer 1 without the BeCUrity element belng visibly changed from the s~cured state to the ~tate o~ use. The re~uirement ~or ~lo ures whic:h permit opening by means of a c~p as well a~ by the complete separation of the alo ure îrom the contain~x ha~
risen lately particularly becau~e it is often required that plastia c:ontain~rs need to be x~3fillable. In sp~te o~ thi~, a larg~ nu~bQr o~ closures are al~o requir~3d ~or con~ain~sr~
which cannot b~ refilled, in which, therefore, an opening move~ent between the closure and the container doe~ not oacur at all. In such ca~e~, it i~ only neae~sary that the po~itiv~ locking means 25 on th~ bar ~ are in functional connection with the }ower part 11 of the closure. Di~erent embodi~ents o~ ~uch clo~ures axe ~hown and de~cribed in the ~ollowing examples although certain d~tails can al80 be realized on closures where the s~curlty element functionally con~cted to th~ oontainer 1.

While the lower part 11 approximately correspond~ to the e~bodiment shown in F~. 1 and 2, the cap 12 connected thereto by khs hlnge 13 is embodied to be relatively low, that is, the aasing wa.ll 20 o~ the cap i8 relatively ~hort. Accordingly, the security element ~1 is in positive connection with thP lower part 11 o~ the closure, but not with the`container.
In contra t to the previously de~crlbed embodiments, wherein the small plate 23 o~ the security element 21 i8 drawn downward from the secured 6tate in the top ~urface 19 of the cap 12 ko the top sur~ace 16 o~ the lower part 11, the small plate 23 remains in the cap 12 in the e~bodiments o~ the closure shown in Figs. 4 and 5. This requires two additional provisions. F.trst, hold:Lng claws 32 mu~t be di~posed below the top surPace 19 o~ the cap 12 to keep the small plate 23 in a lower position, which reprasenkR the ~tate o~ use. Thus, during the initial vp~ning movement of the entire cap 12, th~ bars aonskituting the predetermined break points ~2 are de~troyed. The small plate 23 glide~ downward between khe holdlng claws 3~ until it i~ ~topped there again, whereupon, during the continuation of tha oponing mov~menk, the bar 24 underneath the ~mall plate 23 tears at a predetermined break point 33 espe¢ially provided ~or thi~.

While the e~bodiments shown so ~ar always requixe an exten~ion of the ~e~uring element 21 through the top sur~ac~ o~ the lower part 11, the embodlment of the closure ~hown in Figs. ~ and 9 does not r~uire ~uch 0xten~ionO
Accordingly, ~ree ~pace below the top ~ur~acQ 1~ o~ the lower part 11 is not required. ~hus, the container can have an opening which in it~ 8ize exartly corre~ponds to the lower part 11 of the clo~urs.

Here, too, the sQcurity e~lement 21 has a emall plate ~3 used a~ a ~eal, as well a~ a bar 24 fa~t~ned to it, having a po~itive locking means 25 at the ~nd. In thi~ ca~e, the predetermined break point ~2 are d~sposed on th~ cap 12 or the ~mall pl~te 23 in such a way that tha lattQr can be pivoted around the pred~t~er~ined break points 22. In the manufacturing position in accordance with Fig. B, the small plate 23 extends vertically from the top ~urPace 19 o~ the cap 12.
Accordingly, in thi~ position the bar 24 extend~ parall~l to the top ~ur~ace 19. ~ hook 34 i~ ~olded on the tvp ~urface 16 o~ the lower part 11, the back of which can be engag~d by the positive locking mean~ 25, In a ~ir~t step in the injaction apparatus, khe ~mall plate 23 can be pivoted ~ar enough around ths predetermined break point 22, which i~ now used a~- a pivot point, ~ that the surfac~ o~ the ~mall plate 23 is ~lush with the top ~ur~ace 1~ o~ the cap 12. In a second step, which also takes place ~nside the inj2ction apparatu~, the cap 12 i~ pivoted clo~d, in the cour~e o~
which pre~sure i8 simultaneously ex~rted on the surface of the small plate 23, ~o ~hat thQ po~itiv~ lo~ki~g ~ean~ 25 snap~ b~hind th~ hook 34 without the s~all plat~ ~q~ baing F~229 13 lam/l moved from it position.

In principle, it is pos~ible to dispoE~e th~ hook 34 on the top of the container neak and provide a c:orresponding recess 26 in the top sur:Eace ~6 oî the lower part 11, through which the hook 34 c:an upwardly eactend beyond the top surIace. However, ~n this ~ase, an appropriate anJlular wall on the lower part 11 oî the closure 10 must be provided ~or ealing againet the cont,ainer neck, It is neaessary during th9 assembly oî such a c}o~ure to make sure that the ~3~curity element 21 cannot again pivot upward when plac:ed on the container.

part 11 or the c:ontainer neck a. In thi~ case, the po~itive locking means 25 now engage~ the lower end o:~ the bar ~4 at the ~a~;tening bead 3 of the con~ainer neck 2. With the continuing operling move~ent, the predete~ined break points 22 tear and the ~ecurity element 21 fall~ downward, becau~e it i~ no longer held in th~ cap 12. T:his is po~silbls due to ~rae space F havlng su:Efiaient ~pace ~Qr the bar 24. It can therefore be observed through the ope~irlg 28 in the top sur~ace 19 o~ the cap, which i~ now eacpc3sed, that khe closure 10 i~ no longer in the ~ecured position.
An opening movement of the entire closure 10 has the same ef~ect. If lthe clo~ure 10 is designed aæ a Rorew ClQ8Url3, it iB turned with re~p~3ct to th~ contain~r 1 or the container neck 2 during the initial opening moven ent o~ the entire closure 10. During the initial opening ~nove.m~nt, the po~itive locking means 25 on the bar 24 initially glides only along the lower edge oP the iEa~tening 3: e~ad 3, wheraupon the positive lock:Lng means 25 again engage~ the bank of the ~a;~ening bead in the course o~E the ub~e: [uent upwar~

After initial opening, becau~s the ~ecurity element 21 has per~ormed it~; actual ~unc1:ion, it can be easily removed. However, i~ the recess 26 iG de~igned in ~uch a way that it i~ possible to mainta~n the mall plate 23, which in the secured ætate i~ u~ed as a ~eal, in a po~itiv~ly- a3ld/or ~orced locked ~anner in it, the se¢urlty ele~ent now take~ on an e~thetia task in that it cc)Yer~ the :-rece~s 26 ~l~gantly.

aft~r ~he cap 12 i~ inltially open~d. Howev~r, b~cau~e many users do not arrive at thls concluE~ion, a ba~le 30, ~or example in ~h~ ~;hape o~ a ~pring arm0 may be provlded on the under~ide of the top ~ur~ace 19 o:f kh~ cap 12. A~ a r~sult, during the course of the initial opening moYement of the cap 12, thig3 baffle 30 will automatically 'pre~ on the E;~all plate 23 during the ~ubses~uent closing proce~ and pres~ it into the recess 2 6 .
The em~odiment herein de~crihed ~ there~ore ab~olutely fool-proo~ in it~ ~unction and Dake~ a wrong manipulation impo sibleO Because of th~ functlonal co~meckion between the seaurity ele:ment 21 and tha container 1 provided in this con~tructiorl, it 1~ not possibl~ to ~parate the ~ntire clolurli3 lo ~rom the corltainer 1 without the BeCUrity element belng visibly changed from the s~cured state to the ~tate o~ use. The re~uirement ~or ~lo ures whic:h permit opening by means of a c~p as well a~ by the complete separation of the alo ure îrom the contain~x ha~
risen lately particularly becau~e it is often required that plastia c:ontain~rs need to be x~3fillable. In sp~te o~ thi~, a larg~ nu~bQr o~ closures are al~o requir~3d ~or con~ain~sr~
which cannot b~ refilled, in which, therefore, an opening move~ent between the closure and the container doe~ not oacur at all. In such ca~e~, it i~ only neae~sary that the po~itiv~ locking means 25 on th~ bar ~ are in functional connection with the }ower part 11 of the closure.

While the lower part 11 approximately correspond~ to the e~bodiment shown in F~. 1 and 2, the cap 12 connected thereto by khs hlnge 13 is embodied to be relatively low, that is, the aasing wa.ll 20 o~ the cap i8 relatively ~hort. Accordingly, the security element ~1 is in positive connection with thP lower part 11 o~ the closure, but not with the`container.
In contra t to the previously de~crlbed embodiments, wherein the small plate 23 o~ the security element 21 i8 drawn downward from the secured 6tate in the top ~urface 19 of the cap 12 ko the top sur~ace 16 o~ the lower part 11, the small plate 23 remains in the cap 12 in the e~bodiments o~ the closure shown in Figs. 4 and 5. This requires two additional provisions. F.trst, hold:Lng claws 32 mu~t be di~posed below the top surPace 19 o~ the cap 12 to keep the small plate 23 in a lower position, which reprasenkR the ~tate o~ use. Thus, during the initial vp~ning movement of the entire cap 12, th~ bars aonskituting the predetermined break points ~2 are de~troyed. The small plate 23 glide~ downward between khe holdlng claws 3~ until it i~ ~topped there again, whereupon, during the continuation of tha oponing mov~menk, the bar 24 underneath the ~mall plate 23 tears at a predetermined break point 33 espe¢ially provided ~or thi~.

While the e~bodiments shown so ~ar always requixe an exten~ion of the ~e~uring element 21 through the top sur~ac~ o~ the lower part 11, the embodlment of the closure ~hown in Figs. ~ and 9 does not r~uire ~uch 0xten~ionO
Accordingly, ~ree ~pace below the top ~ur~acQ 1~ o~ the lower part 11 is not required. ~hus, the container can have an opening which in it~ 8ize exartly corre~ponds to the lower part 11 of the clo~urs. The manufacturing po~tion of the closure i8 shown in Fig. 8. It iB molded in the completely open position. Here, too, the sQcurity e~lement 21 has a emall plate ~3 used a~ a ~eal, as well a~ a bar 24 fa~t~ned to it, having a po~itive locking means 25 at the ~nd. In thi~ ca~e, the predetermined break point ~2 are d~sposed on th~ cap 12 or the ~mall pl~te 23 in such a way that tha lattQr can be pivoted around the pred~t~er~ined break points 22. In the manufacturing position in accordance with Fig. B, the small plate 23 extends vertically from the top ~urPace 19 o~ the cap 12.
Accordingly, in thi~ position the bar 24 extend~ parall~l to the top ~ur~ace 19. ~ hook 34 i~ ~olded on the tvp ~urface 16 o~ the lower part 11, the back of which can be engag~d by the positive locking mean~ 25, In a ~ir~t step in the injaction apparatus, khe ~mall plate 23 can be pivoted ~ar enough around ths predetermined break point 22, which i~ now used a~- a pivot point, ~ that the surfac~ o~ the ~mall plate 23 is ~lush with the top ~ur~ace 1~ o~ the cap 12. In a second step, which also takes place ~nside the inj2ction apparatu~, the cap 12 i~ pivoted clo~d, in the cour~e o~
which pre~sure i8 simultaneously ex~rted on the surface of the small plate 23, ~o ~hat thQ po~itiv~ lo~ki~g ~ean~ 25 snap~ b~hind th~ hook 34 without the s~all plat~ ~q~ baing F~229 13 lam/l moved from it position.

In principle, it is pos~ible to dispoE~e th~ hook 34 on the top of the container neak and provide a c:orresponding recess 26 in the top sur:Eace ~6 oî the lower part 11, through which the hook 34 c:an upwardly eactend beyond the top surIace. However, ~n this ~ase, an appropriate anJlular wall on the lower part 11 oî the closure 10 must be provided ~or ealing againet the cont,ainer neck, It is neaessary during th9 assembly oî such a c}o~ure to make sure that the ~3~curity element 21 cannot again pivot upward when plac:ed on the container.

I~ is Imable to pu~;h the pivot lever 50 sideways during the iniltial clos~ng process in the injection mold, because the pivot lever 50 is still ~3upported by the in~eçtion core part 60. This can be E;een in Figs. 22b and 22c. The po~;ition of the pivot lever in the through-hole 52, in wh~ ch it i~# supported by ~eing slightly cantad, i~ as~ured in ~3pite o~ the pre-stra.5~ed pressure of the small spring plate 54 against tlle pivot lever 50. During the ini.tial opening movement, the pivot arm surîace 53 iE3 pullad out o~ ~he through-hole 52 and the ~3~all spring plate 54, which i8 pre-stressed, simultaneou~;ly puc~hes the pivot leve~ 50 slightl~f in the direction toward the ls:~wer part lï. Due to a certain restorillg force, the pivot levex 50 i~3 able to turn approximately back into the original poE~ition~ as shown in Flg. 22f~. The visually recognizable state o~ usa i~ attained, even upon inltial opening, becau~e the through-hole 52 i~ now uncovered.
During subse~uent closing of the closure a~ter initial opening, the s2cur~d state in accordance with ~ig. 2~e can no longer be attained. During sub~equent clo~ing, the ba~le 54 now again pres~e~ on the pivot lever 50, but since the ~upporting e~ect o~ the inje~tion aore p~rt 60 i~ no long2r e~ective, the piVQt lever 50 i~ auto~atically pushed down t~ward the lower part 11. The rece~ 2~, through which the ln~tion core part 60 ~xtends dur~ng manugacture and ini~ial olo~ing, i3 now open.

The po~;ition of the pivot lever in the through-hole 52, in wh~ ch it i~# supported by ~eing slightly cantad, i~ as~ured in ~3pite o~ the pre-stra.5~ed pressure of the small spring plate 54 against tlle pivot lever 50. During the ini.tial opening movement, the pivot arm surîace 53 iE3 pullad out o~ ~he through-hole 52 and the ~3~all spring plate 54, which i8 pre-stressed, simultaneou~;ly puc~hes the pivot leve~ 50 slightl~f in the direction toward the ls:~wer part lï. Due to a certain restorillg force, the pivot levex 50 i~3 able to turn approximately back into the original poE~ition~ as shown in Flg. 22f~. The visually recognizable state o~ usa i~ attained, even upon inltial opening, becau~e the through-hole 52 i~ now uncovered.
During subse~uent closing of the closure a~ter initial opening, the s2cur~d state in accordance with ~ig. 2~e can no longer be attained. During sub~equent clo~ing, the ba~le 54 now again pres~e~ on the pivot lever 50, but since the ~upporting e~ect o~ the inje~tion aore p~rt 60 i~ no long2r e~ective, the piVQt lever 50 i~ auto~atically pushed down t~ward the lower part 11. The rece~ 2~, through which the ln~tion core part 60 ~xtends dur~ng manugacture and ini~ial olo~ing, i3 now open. Thu~ it is po~ibl~ ~or the pivot lever 50 to be pu~hed downward by the ba~ 54 toward F-229 20 lam/l 2 ~3~5 ~
, the lower part 11 ~ar enough that the pivot lever 50 plvots intQ the recess 26 and completely clo~e~ it o~ in the position of usa in accordancQ with Fig. 2~ ccordingly, no predetermined brçaX point~ are re~uir~d with this embodiment. ~owever, it i~ nece~ary agaln with this embodlment that th~re be a free ~pace ~F below the top ~urface 16 of the lower part 11 between the casing wall 14 and the ealing annular.wall ~7 around the ~pout 17.
The numerou3 exe~plary e~bodiments are intended to show the varied possibilitie~ o~ the general inventive concept. In each o~ the embodiment~, however, there i~ a ~ecurity element 21 which attains a visually recognizable dif~erent position or shape upon the initial opening movement o~ the closure, without any additional manipulation being r~quired other than the opening movement o~ the closure. Aacordingly, it i3 unimportant whether the security element 21 i8 conn~cted in one pieae to the cap 12 or the lower part 11 in the ~ecurad ~tate~ Th~ type o~
movemenk made by the security element duri~g the initial opening is al80 dif~erant. ~hi~ may be a more or le~s vertlcal tran~lational movement or a rotating movement around a horizontal axis or a vertical axi~.
