Abstract
ABSTRACT OF THE DISCLOSURE
For tent-type paperboard containers as well as other containers, a spout fitment is attached surrounding a hole in the container. The fitment spout has internal threads and an external flange which seals around the hole and is fixed to the container by thermal means, adhesive or the like. The cap has a top disk from which an externally threaded skirt depends.
The exterior of the skirt has gripping ribs to assist in screwing ad unscrewing the cap. The lower edge of the skirt seals against a sealing membrane on the spout. Surrounding the skirt is a tamper-evident band attached to the lower edges of the ribs by frangible bridges. The tamper-evident band has locking means engaging complementary locking means on the fitment.
Thus, the cap cannot be unscrewed without removing the tamper-evident band. By unique design, the fitment and cap may be molded in one mold cavity.

3 ~$) SPOU~ FI~ENT CI~SURE l?WG
I~v~ntor: Daniel Luch Brian M. Adams BACX~ROUND OF THE II~TION -~ield of he Invell~iQn ~rhl6 inventiorl rel~te~ to a new and improsred spout ~lt:ment and plug for clo~ing the fiame!. More particularly the invQntion relatQ~ to a ~ltment which fitE~ arouncl a hole in a panel o~ a paperboard carton or around a hole in a flexible contalnert or th~ like, 6uch a~ u~ed ~or packaging li~uid producte and powders and to a closure for ~uch I ~ t~ent .
Descriptlon o~ R~late~_~
A typical prior art ~ltiment ~nd cap i~ shown ln Fig. l of the ~ccompanying drawinys and i8 discu6sed in the pr~rred embodiZnents portion o~ thi~ ~pecifica-tion. Generally peaking, pxior fit:ment~ have ~pout6 with ~x~ernal thread~ closed by oap3 w~ th interrlal ~hreads. So~e fitment~ are used in con~unction with pla~tio bag oontainer~, the fitment bein~ lntegr~lly welded to the pl~tic bag. Oth~r prior art ~ltment~
are attach~d to a polym~r-coated paperbo~xd co~tainer ~uch ~ a gable~topped hal~-~allon cont~lner.
~enerally, prior art fit~e~ts ~or paperboard cartons include a ~in ~lange which i8 welded ~o ~he 6ur~ace of the contain~r. The closure include~ a ~oll ~eal which A-54104/JC ~l-~eal~ the ~outh of tha spout and a liner for the cap which ~erves a resealing ~unction. Attachment to the polymer-coated paperboAr~ i8 accompli~hed by welding the flange o~ the ~pout to the polymer coating. Upon initial removal, the tamper evident foil ~eal i8 removed and di~ards~.
Fitment~ of the prior art have a number of deficiencies as compared with the present ~vention.
In the ~ir~t place, they employ multiple componenta which increa~e the cost o~ the combination very greatly over the 6imple ~tructure cf the present lnven~ion.
Secondly, a~sembly i~ dif~icult and involves rotary equipment whioh i~ dif~icult to control in praetice and i8 axpen~iv~ to in~tall. Thirdly, because o~ th~ ~act tha.t the prior art spout~ are ~xternally threaded, the diameter o~ the open~ ng in the ~pout iB restricted ina~much a~ there i~ only limited spaae on the panel of the container on which the flange can be located, thereby reducing the diameter o~ the fitment flange and corre6pondingly the diameter of the 6pout. Finally, commercially available fltm2nt-closure combinations have no ~xternal tamper--avident features (as contra~ted with th~ intarnal fo~ al of the ~pout op~ning3.
SUM~ARY OF ~HE_INVEN~ION
~5 one e~bodi~ent Or ths pre~nt invention employs a fi~ment having ~ spout which i~ int~rnally threa~ed an~ having a flanga or other ~aans which ~
welded or otherwi~ adhered to the container panel on which the ~itment i8 in~tall~d. ~h~ clo~ur~ i~ an externally threaded plug closure whiah ~eals again~t membr~n~ on the fitment, which membrane al o protect~
the exposed edge o~ th~ holQ formed in the conta$ner panel. A tamper-evident band on tha clo~ure i~ joined to tha clo~ure by a plurality o~ ~rangible bridges or ~5 the parts ~y ba ~niti~lly connected by other frangible ~ean~ embly of the cap on th~ ~itm~nt ~e preferably performed by a direct axlal pushing movemen~, the thraad~ slipping past each other during the ~xial movement. Th~ lower edge o~ the tamp~r-evident band has ~ngagem~nt meana wh~ch fit into complementary engagem2nt maan~ on the ~poutO The inter-engagement o~ these ~ean~ prevent~ rot~tion of the cap 80 long aa the bridyes whi~h ~oin tha band to the cap are intact. Thu~, ~fter axia~ a~sembly the threaded plug cannot be removed prior to re~oval of the ta~par evident band.
A~ an additional feature, the plug and 6pout may be mold d ~imultaneou~ly in a ~ingle cavity in an in~ection molding machine. Further, a6 the part~ are e~ec~ed from the cavity, the threaded plug may be moved axially 80 that it fits in~de the spout and the threads of the 6pout and plug lntar engage.
In another e~bodiment, the parts ~ay be inter~itted by a ~riction fit between the exterior of the plug and the interior o~ the 6pout.
As those 6k~11ed in the art will realize, materials such as polyolefins having relatively high flexibility and toughnes~ will be most ~uitable in praotice of the invantion~

~ESCRI~TION OF P~EFERRED EMBODI~NTS
Re~erence will now be ~adQ in detail to the preferred e~bod~ents o~ th~ lnvention, exampl~ o~
which are illu~tra~ed ln the accompany$ng drawlngs.
~hile the invsntion will be de~cribed in con~unction with the pre~erred embodimQnts~ it will ~e understood that they are not intended to l~mit the inventlon to A-54104/JC -4~
~J ~ 3~?~.3 tho6e embodlment~. On the contrary, the ~vention is intended to cover alternatives, modiEication~ and egulvalent~, which may be lncluded within the 6pirit and acope of the invention as de~in~d by the app~nded claims.
Directing attention now to tha typical prlor art ~tructure shown in Fig. 1, a ~arton o~ paperboard coated with a Eultable polymer ha~ a panel 2l ~ormed with a hole 22. Surrounding hole 22 i~ a ~itm~nt ~3 10 having an upstanding spout 24 ~or~ed with ~xternal threads 2~. The lower edge o~ spout 24 ha~ an external ~lange 27 which iB cau~ed to adhere to the panel 21 by welding, adhesive or other 6uit2ble means.
The prior art cap 3l has a top di6k 32 ~rom 15 which depend~ a ~kirt 33 having internal thxead~ 34 mating with th~ threads 26. Init~ally, the cap 31 may be provided with a liner 36 which ~unction~ a~ a re-closure ~eal and al~o with a ~oil ~eal 37 which ~eal~ against the upp~r end o~ thQ ~pout 24 and 20 provides ta~per-evident fQature~. Once the seal 37 ifi removed, the liner 36 perform~ a sealing function on re-closure.
Some o~ the advantage~ of the pre88nt inventlon over prior art structures such as thQ typical 25 a~sembly ~hown in Fig. 1 have heretofore be2n described.
A preferred ~tructure of ~h~ present invention i~ sho~ in F~gB. 2 - ll. Fitment 41 hae an upstanding spout 42 ~ormed with a top edge 43 and 30 having int~rnal ~hreads 44. Prsferably the thr2ad~ 44 ~rQ multipl~ lezd ~hreade, ~ince ~ h~r~inafter deæcribed) thi~ ~alances the gating of tha 6pout (~ae below description~ o~ Fig~. l0 ~nd ll).
~low thread~ 44~ ~pout i~ ~ormed with a 35 downward-inward slanted æeal membrane 48 which, as ~hown in Fig. 3, p~rforms a ~ealing funation with ths cloæure a~ hereinafter ~ppaars. Diametrically opposed 2 ~
ratchets 46 are ~ormed $n the top edge 43 for the purpose of locking with the tamper-2vident band o~ the clo~ura as hereina~ter appear6. At the bottom of the fitment i~ an enlarged peripheral flange 47, the underside Or which i~ aaufied to adhere to the panel 21.
Clo~ur~ 51 functions a~ a plug to clo~ the ~pout 42. It i~ ~ormed with a top di6k ~2 h~vlng a rounded corner 53 ~rom whiah depends a ekirt 54. The upper pnrt$on of ~Xirt 54 i~ formed with vertioal ribs 56 which extend around the corner 53 and partially inward o~ the di~k 52. Rlbs 56 are ~eparated by ~paoes 57. By gripping the rib~ 56 ~h~ user may ~urn the clo~ure 51. Midway o~ th~ sklrt 54 and imm~dlately below the ribs 55 i6 an external wall 58 and below the wall 58 are thread~ 59 which mate with the threads 44.
8urround~ng the ~klrt 54 i8 a narrow tamper-evid~nt band 61 which ia conn2ct~d to the lower end~ o~
~oma of the ribs 56 by horizontal frangtble bridg~s 62.
At diametrically ~paced position6 on the undex ~ide of band 61 are depending pawl~ 63 which engage the ratchet~ 46 of 6pout 4a to re~trai,n rotation of closure 51 relative to ~itment 41 60 long as the bridge~ 62 are intaat. One or more t~ar tab~ 64 ~h~re ~hown ~ two in numb~r and depending ~rom band 61. immediately outward of pawls 63) are attached to the band 61. By pulling the tab 64 u~ward, the band 61 ~ay be ~i connected ~rom the closure 51 and the closure ~ay be turned relative to the fitment since th pawls 63 are out of engagement with the ratchet6 46. ~owever, the removal o~ band 61 or any tQaring o~ th~ bridge~ 62 gives evldencQ o~ tampering with the contsnts of ths cont~iner. To facilitats removal, bridge~ 62 arQ
o~itted in the ~icinity of tsar tabs 63 (See Figs. 3, 5 and 6) The consumer ~ay turn clos~r~ 51 to open and close th~ aontain~r. In the clo6ed condition, the ~nd A~54104/JC -6~
~ 3~.3 66 of the ~kirt 54 seal~ against the ~eal ~ember 48 o~
~itment 41.
One preferred ~ean~ for the production of the fitmant ~l and clo6ure 51 i8 ~hown in Fig8. 10 and 11 whereby the two parts may be made simultaneously in a ~ingle cavity of a pla tic $njection mold. Thu~ in the mold, the fitment 41 i~ positioned below tha ~106ure 51. A~ 6hown in Fig. ll, there are gate~ 71 connectin~
the fitment to the clo~ure. Gate~ 71 ar2 po~tioned to coinclde with the theoretical pro~ections o~ the lower end~ (or run-out6) of h~lical threads 59. The plastio i~ in~ectQd at the top o~ the clo~ur~ and the ~olten pla6tic extend~ through the gate 71 into the top o~ the spout 42. Acoordingly the two part~ may be molded simul~aneously. In order to ~eparate the part~, the gate 71 is fxactured. Such ~racture ~ay be accompli~hed merely by ~ushing axially downward on the closure, the threads 59 olipping over the thread~ 44.
It will be understood, however, that the parts may be molded separately. When molded simultaneously/ by proper ~old construction, tha parts may be as~emblsd before being e~ected ~rom the mold.
Fig. 12 illustrat~s an alt~rnate cons'ruction. In thi~ modification, ~ oontinuou~
frangible web conneotion 76 oonno~t~ the plug to the ~op adga 43a cirau~fer~ntially around the part~. ~he parts may be installed on the container in the condition ~hown in Fig. 12. So long as th~ ~onnector 76 i8 lntact, the consumer iR a~sured that th~rs has 3C been no tampering with the container. ~t th~ time of con~mption, the user fracture~ the connection 76 - either by tw~stlng the closura 51a or other conven~ent mean~O ~h~ closurQ 51a m~y be ~nstalled on the ~itment 41a after par~ o~ the contents o~ tha container have been di~pen~sd merely by screwing ~he closure 51~ $nto the spout ~a.

More particularly the invQntion relatQ~ to a ~ltment which fitE~ arouncl a hole in a panel o~ a paperboard carton or around a hole in a flexible contalnert or th~ like, 6uch a~ u~ed ~or packaging li~uid producte and powders and to a closure for ~uch I ~ t~ent .
Descriptlon o~ R~late~_~
A typical prior art ~ltiment ~nd cap i~ shown ln Fig. l of the ~ccompanying drawinys and i8 discu6sed in the pr~rred embodiZnents portion o~ thi~ ~pecifica-tion. Generally peaking, pxior fit:ment~ have ~pout6 with ~x~ernal thread~ closed by oap3 w~ th interrlal ~hreads. So~e fitment~ are used in con~unction with pla~tio bag oontainer~, the fitment bein~ lntegr~lly welded to the pl~tic bag. Oth~r prior art ~ltment~
are attach~d to a polym~r-coated paperbo~xd co~tainer ~uch ~ a gable~topped hal~-~allon cont~lner.
~enerally, prior art fit~e~ts ~or paperboard cartons include a ~in ~lange which i8 welded ~o ~he 6ur~ace of the contain~r. The closure include~ a ~oll ~eal which A-54104/JC ~l-~eal~ the ~outh of tha spout and a liner for the cap which ~erves a resealing ~unction. Attachment to the polymer-coated paperboAr~ i8 accompli~hed by welding the flange o~ the ~pout to the polymer coating. Upon initial removal, the tamper evident foil ~eal i8 removed and di~ards~.
Fitment~ of the prior art have a number of deficiencies as compared with the present ~vention.
In the ~ir~t place, they employ multiple componenta which increa~e the cost o~ the combination very greatly over the 6imple ~tructure cf the present lnven~ion.
Secondly, a~sembly i~ dif~icult and involves rotary equipment whioh i~ dif~icult to control in praetice and i8 axpen~iv~ to in~tall. Thirdly, because o~ th~ ~act tha.t the prior art spout~ are ~xternally threaded, the diameter o~ the open~ ng in the ~pout iB restricted ina~much a~ there i~ only limited spaae on the panel of the container on which the flange can be located, thereby reducing the diameter o~ the fitment flange and corre6pondingly the diameter of the 6pout. Finally, commercially available fltm2nt-closure combinations have no ~xternal tamper--avident features (as contra~ted with th~ intarnal fo~ al of the ~pout op~ning3.
SUM~ARY OF ~HE_INVEN~ION
~5 one e~bodi~ent Or ths pre~nt invention employs a fi~ment having ~ spout which i~ int~rnally threa~ed an~ having a flanga or other ~aans which ~
welded or otherwi~ adhered to the container panel on which the ~itment i8 in~tall~d. ~h~ clo~ur~ i~ an externally threaded plug closure whiah ~eals again~t membr~n~ on the fitment, which membrane al o protect~
the exposed edge o~ th~ holQ formed in the conta$ner panel. A tamper-evident band on tha clo~ure i~ joined to tha clo~ure by a plurality o~ ~rangible bridges or ~5 the parts ~y ba ~niti~lly connected by other frangible ~ean~ embly of the cap on th~ ~itm~nt ~e preferably performed by a direct axlal pushing movemen~, the thraad~ slipping past each other during the ~xial movement. Th~ lower edge o~ the tamp~r-evident band has ~ngagem~nt meana wh~ch fit into complementary engagem2nt maan~ on the ~poutO The inter-engagement o~ these ~ean~ prevent~ rot~tion of the cap 80 long aa the bridyes whi~h ~oin tha band to the cap are intact. Thu~, ~fter axia~ a~sembly the threaded plug cannot be removed prior to re~oval of the ta~par evident band.
A~ an additional feature, the plug and 6pout may be mold d ~imultaneou~ly in a ~ingle cavity in an in~ection molding machine. Further, a6 the part~ are e~ec~ed from the cavity, the threaded plug may be moved axially 80 that it fits in~de the spout and the threads of the 6pout and plug lntar engage.
In another e~bodiment, the parts ~ay be inter~itted by a ~riction fit between the exterior of the plug and the interior o~ the 6pout.
As those 6k~11ed in the art will realize, materials such as polyolefins having relatively high flexibility and toughnes~ will be most ~uitable in praotice of the invantion~

~ESCRI~TION OF P~EFERRED EMBODI~NTS
Re~erence will now be ~adQ in detail to the preferred e~bod~ents o~ th~ lnvention, exampl~ o~
which are illu~tra~ed ln the accompany$ng drawlngs.
~hile the invsntion will be de~cribed in con~unction with the pre~erred embodimQnts~ it will ~e understood that they are not intended to l~mit the inventlon to A-54104/JC -4~
~J ~ 3~?~.3 tho6e embodlment~. On the contrary, the ~vention is intended to cover alternatives, modiEication~ and egulvalent~, which may be lncluded within the 6pirit and acope of the invention as de~in~d by the app~nded claims.
Directing attention now to tha typical prlor art ~tructure shown in Fig. 1, a ~arton o~ paperboard coated with a Eultable polymer ha~ a panel 2l ~ormed with a hole 22. Surrounding hole 22 i~ a ~itm~nt ~3 10 having an upstanding spout 24 ~or~ed with ~xternal threads 2~. The lower edge o~ spout 24 ha~ an external ~lange 27 which iB cau~ed to adhere to the panel 21 by welding, adhesive or other 6uit2ble means.
The prior art cap 3l has a top di6k 32 ~rom 15 which depend~ a ~kirt 33 having internal thxead~ 34 mating with th~ threads 26. Init~ally, the cap 31 may be provided with a liner 36 which ~unction~ a~ a re-closure ~eal and al~o with a ~oil ~eal 37 which ~eal~ against the upp~r end o~ thQ ~pout 24 and 20 provides ta~per-evident fQature~. Once the seal 37 ifi removed, the liner 36 perform~ a sealing function on re-closure.
Some o~ the advantage~ of the pre88nt inventlon over prior art structures such as thQ typical 25 a~sembly ~hown in Fig. 1 have heretofore be2n described.
A preferred ~tructure of ~h~ present invention i~ sho~ in F~gB. 2 - ll. Fitment 41 hae an upstanding spout 42 ~ormed with a top edge 43 and 30 having int~rnal ~hreads 44. Prsferably the thr2ad~ 44 ~rQ multipl~ lezd ~hreade, ~ince ~ h~r~inafter deæcribed) thi~ ~alances the gating of tha 6pout (~ae below description~ o~ Fig~. l0 ~nd ll).
~low thread~ 44~ ~pout i~ ~ormed with a 35 downward-inward slanted æeal membrane 48 which, as ~hown in Fig. 3, p~rforms a ~ealing funation with ths cloæure a~ hereinafter ~ppaars. Diametrically opposed 2 ~
ratchets 46 are ~ormed $n the top edge 43 for the purpose of locking with the tamper-2vident band o~ the clo~ura as hereina~ter appear6. At the bottom of the fitment i~ an enlarged peripheral flange 47, the underside Or which i~ aaufied to adhere to the panel 21.
Clo~ur~ 51 functions a~ a plug to clo~ the ~pout 42. It i~ ~ormed with a top di6k ~2 h~vlng a rounded corner 53 ~rom whiah depends a ekirt 54. The upper pnrt$on of ~Xirt 54 i~ formed with vertioal ribs 56 which extend around the corner 53 and partially inward o~ the di~k 52. Rlbs 56 are ~eparated by ~paoes 57. By gripping the rib~ 56 ~h~ user may ~urn the clo~ure 51. Midway o~ th~ sklrt 54 and imm~dlately below the ribs 55 i6 an external wall 58 and below the wall 58 are thread~ 59 which mate with the threads 44.
8urround~ng the ~klrt 54 i8 a narrow tamper-evid~nt band 61 which ia conn2ct~d to the lower end~ o~
~oma of the ribs 56 by horizontal frangtble bridg~s 62.
At diametrically ~paced position6 on the undex ~ide of band 61 are depending pawl~ 63 which engage the ratchet~ 46 of 6pout 4a to re~trai,n rotation of closure 51 relative to ~itment 41 60 long as the bridge~ 62 are intaat. One or more t~ar tab~ 64 ~h~re ~hown ~ two in numb~r and depending ~rom band 61. immediately outward of pawls 63) are attached to the band 61. By pulling the tab 64 u~ward, the band 61 ~ay be ~i connected ~rom the closure 51 and the closure ~ay be turned relative to the fitment since th pawls 63 are out of engagement with the ratchet6 46. ~owever, the removal o~ band 61 or any tQaring o~ th~ bridge~ 62 gives evldencQ o~ tampering with the contsnts of ths cont~iner. To facilitats removal, bridge~ 62 arQ
o~itted in the ~icinity of tsar tabs 63 (See Figs. 3, 5 and 6) The consumer ~ay turn clos~r~ 51 to open and close th~ aontain~r. In the clo6ed condition, the ~nd A~54104/JC -6~

One preferred ~ean~ for the production of the fitmant ~l and clo6ure 51 i8 ~hown in Fig8. 10 and 11 whereby the two parts may be made simultaneously in a ~ingle cavity of a pla tic $njection mold. Thu~ in the mold, the fitment 41 i~ positioned below tha ~106ure 51. A~ 6hown in Fig. ll, there are gate~ 71 connectin~
the fitment to the clo~ure. Gate~ 71 ar2 po~tioned to coinclde with the theoretical pro~ections o~ the lower end~ (or run-out6) of h~lical threads 59. The plastio i~ in~ectQd at the top o~ the clo~ur~ and the ~olten pla6tic extend~ through the gate 71 into the top o~ the spout 42. Acoordingly the two part~ may be molded simul~aneously. In order to ~eparate the part~, the gate 71 is fxactured. Such ~racture ~ay be accompli~hed merely by ~ushing axially downward on the closure, the threads 59 olipping over the thread~ 44.
It will be understood, however, that the parts may be molded separately. When molded simultaneously/ by proper ~old construction, tha parts may be as~emblsd before being e~ected ~rom the mold.
