positioned on a pouring spout 16 Pl~tl~nll;ng upwardly from an end wall 18 of the tamper-evident cont~;nf~r closure member 12.
The pouring spout 16 is comprised of a generally cylindrically-shaped side wall 20 ,~1ft~n(9;ng upwardly from the end wall 18 of the closure member 12 to a top end wall portion 22 ~lPf;n;ng an ;nt~r;~r chamber 24. Formed upwardly from the top end wall portion 22 and centrally positioned thereto, there is provided a conically-shaped plug portion 26. The top end wall portion 22 is formed with a circularly-shaped channel 28 ~- tPn~;n~
downwardly from a top surface 30 peripherally about the end wall portion 22. A plurality of elongated orifices 32, referring to Figure 3, are provided at the bottom of the channel 2 8 providing f luid communication to the chamber 24 of the pouring spout 16 .
The top end wall portion 22 is formed with an outwardly l~t~n~;ng ~5 annular flange 34. The side wall 22 is formed with a lower outwardly extending annular shoulder 38, as more fully hereinafter described .
The pull-push pouring spout closure member 14 includes a cylindrically-shaped side wall portion 40 extending upwardly to a top wall portion 42 having a centrally-formed opening 44 therein. The top wall portion 42 is formed with an annular ring 46 extending downwardly from an inner surface 48 shereof. Th~

~ 217~9~4 ~' annular ring 48 is sized to provide frictional fitting interrelationship within the annular channel 28 of the pouring spout 16 as more fully hereinaf ter discussed . The top wall portion g2 proximate the cylindrically-shaped side wall 40 is formed with an outwardly f.~tf~nrl;ng flange 50. The side wall portion 40 is connected to a tamper-evident ring 52 by a plurality of radially disposed frangible elements 54 (one shown). An inner surface 56 o~ ~he side wall 40 is provided with an inwardly r~ftPn~l;n~ annular shoulder 58. An inner gurface 60 of the tamper-evident ring 52 is provided with an inwardly exte~;:Lding annular shoulder 62.
The tamper-evident rrmt;i;n~ closure member 12 includes a closure portion similar to the closure member disclosed in U . S .
Patent 4,625,875, assigned to the same assignee as the present invention, and hereby incorporated by reference. The closure member 12 of the closure assembly lO is compri8ed of the upper end wall 18 including pouring spout 16 from which downwardly depends a cylindrically-shaped side wall 64 and a ring-shaped tamper-evident skirt member 66 ~rf~n~l;ng from the cylindrically-shaped side wall 64 by a plurality of frangible arm members 68. The frangible arm members 68 are angularly-disposed with reference to a center axis of the closure member 12 thereby 3~orminr~ a -~ 21~
ring-shaped opening 70 between the cylindrically-shaped side wall 64 and the tamper-evident skirt member 66.
The closure a6sembly 10 is formed o~ a suitable thermoplastic material, such as low density polyethylene or like thermoplastic materials possessing certain characteristics of flexibility, as will hereinafter become more apparent. The arm members 68 are configured and angularly disposed to provide a spring-like action betweer, the skirt memoer 66 and the gide wall 64 of the rr,nt;l;nPr closure member 14 of the closure assembly 10.
The end wall 18 of the closure 10 is formed with an outer surface portion 72 and an inner gurface portion 74 including a cylindrically-shaped ;ntPrn~l centering element 76 depending inwardly essentially co;nridPnt to the cylindrically-shaped side wall 64 to facilitate centering on a crnt~;nPr as more fully hereinafter discussed. An outer surface portion 78 of the internal rf'ntPr;n~ element 76 proximate the inner surface portion 74 of the end wall 18 ig provided with a groove 80. The cylindrically-ghaped side wall 64 is formed with an internal thread 84 and with a knurled or serrated outer surface portion 86 to f~ri 1 i t~te in clo8ure member removal and closure member tightening about a rrnt~inPr as more fully hereinafter discussed . _ ' ~ 2177g~4 ~
The tamper-evident skirt member 66 is formed with an inwardly extending annular shoulder 88, as more fully hereinafter discussed. The external diameter of the skirt member 66 is substantially equal to the external diameter of the closure member 12, and essentially equal to the ~tF~rn~ r^tPr of a knurled portion 86 of the closure memiber 12 thereby simplifying bottling assembly requirementg. An upper surface portion 90 of the skirt member 66 is formed with a plurality of wall sections 92 P7~tf~n~l;n~
partially upwardly into the opening 70.
In operation, the tamper-evident pouring spout closure member 14 is disposed over the pouring spout 16 and with a downward force, the pouring spout closure member 14 is caused to be downwardly displaced onto the pouring spout 16 to a point where the shoulder 58 of the upper side wall portion 40 and the shoulder 62, respectively, are positioned beneath shoulder 36 and 38 of the pouring spout 16, respectively. During such downward movement, the annular ring member 46 i8 caused to be positioned within the channel 28 of the pouring spout 16 in ~rictional engagement thereby sealing the orifices 32 between the closure member 14 and the chamber 24 of the pouring spout 16. In such position, the tamper-evident ring 52 affixed by the frangible . _ .
- 21~7904 ~
elements 54 to the side wall po~tion 40 of the pouring spout closure member 14 evi~lpnr;n~ integrity to the pouring spout 16.
The closure member 10 cooperates with container, generally ;nrl;~tPtl as 100 (e.g., a 16 oz. bottle cr~n~A;n;ng water, sports beverages or the like), referring particularly to Figure 1, ;n~ ;n~ a neck portion of 102, including P~PrnAl threads 104, an inwardly P~Pn~li ng lip portion 106 on an inner portion thereof and a skirt ridge or collar 108 formed on an P~tPn~lP~ surface thereof .
The internal threads 84 of the C~n~;nPr closure member 12 and the external threads 104 of the container 100 are preferably of the multiple thread type whereby the container closure member 16 asæumes a level position of suostantially coaxial alignment with the axis of the .-r,n~;nPr 100 when disposed on the neck 102 of the C~nti~;nPr 100. After such positioning, a downward longitudinal force is applied to the closure assembly 10 thereby to cause the closure member 10 to be displaced onto the neck 102 of the ~ n~AinPr 100, i.e., the container closure member 12 is pushed onto the neck 102 of the C~ntA;nPr 100 to a point where the annular shoulder 88 formed on the skirt member 66 overrides with the ridge or collar 108 formed on the neck 102 of the container 100. During such downward movement of the container closure _ f 217~
portion, the wall sections 92 of the skirt member 66 contact the lower surface portion of the side wall 64 to drive the skirt member 66 into the tamper-evident mode, i . e ., the crn~ n~r closure member 12 may not now be removed from the c~nt~;n,~r 100 without fracturing the frangible arm members 68. Removal of the crnt:l;ner closure portion from the rr,nt~;nf~r 10 retains the tamper-evident skirt member 66 about the neck portion 102 of the container 100 . ~dditionally, the inwardly ,~rrn~1i n~ lip 106 cooperates with groove 80 of the closure 10 to provide for additional cl,osure- integrity between the closure 10 and the container 100, particularly for uses relating to carbonate beverage bottling.
Conseriuently, after assembly onto a rrnt;l;n~r, rf~nt~;n~r and pouring spout integrity are ensured by the existence of intact frangible elements 68 between the side wall 64 and skirt member 66 of the rrnt;l;nPr closure member 12 and the existence of intact frangible elements 54 between the side wall portion 40 and skirt member 52 o~ the pouring spout closure r '^r 16.
An upward force on lower sur~ace portion of the annular flange 50 of the pouring spout closure member 14, such as by finger pressure, causes the frangible elements 54 to fracture as a result bf contact between the shoulder 62 of the skirt member g _ f~ 21~7~04 ~
52 with the shoulder 38 of the pouring spout 16 thereby cau8ing the skirt member 52 to remain positioned about a lower neck portion of the pouring spout 16. The side wall section 40 of the pourirg spout ~ nt~inf~r member 12 nnntin~ in upward mo~ement until arrested by contact of the shoulder 58 thereof with the annular flange 50 of the pouring spout 16 with concomitant fluid access to the chamber 24 of the pouring spout 16 via the ori~ices 32 and a fluid passage formed between the top surface 30 of the pouring spout 16 and a lower surface o~ the end wall portion 42 of the pouring spout closure member 14 thence through the opening 44 .
Positive closing of the pouring spout closure member 14 on the pouring spout 16 is effected by pushing the pouring spout closure member 14 downwardly on the pouring spout 16 to a point where the shoulder 58 overrides and is positioned in interlocking r~ t;r~n~h;p with shoulder 36 of the pouring spout 16.
Concomitant frictional ,,n~r~ nt exists between the annular ring 46 of the pouring spout closure member 16 within the channel 28 of the pouring spout 16. Data frictional fitting is achie~ed by forming the annular ring 46 of thickness slightly greater, e.g., 0 . 020 mm greater than the width of the annular channel 28 .
~. ~ 21~0~ ~
Once the cnnt~;nPr 100 re~uires refilling, it is necessary to destroy the integrity of the rnnt~;nPr closure member 12 with the rr,nt~;nPr 100 which is e~fected by counterclockwise rotation of the rr,nt;~inPr closure mem~er 12 about the neck portion 102 of the container 100 to a point where the frangible arm members 68 are fractured thereby leaving the tamper-evident ring 66 disposed about the neck portion 102 of the ront~;nPr 100. Turning of the rr,nt;~;nPr closure member 12 about the cnnt~;nPr 100 is rnnt;nllPfl to the point of removal of the closure assembly 10 from the cr~nt~;nPr 100 thereby permitting refilling of the container 100 with any preselected liquid. After refilling, the closure assembly 10 may be repositioned by twisting on the cnnt~;nPr 100 with the pull-push pouring spout closure member 14 cooperating with the pouring spout 16 of the closure assembly as hereinaf ter discussed.
While the present invention has been clescribed in connection with an exemplary ~ t thereof, it will be understood that many modifications will be apparent to those of ordinary skill in the art; and that this application is intended to cover any adaptations or variations thereof. Therefore, it is manifestly ;ntPn~ rl that this invention be only limited by the claims and the equivalents thereof.
Currently available closure members having pouring spouts are often inadequate, and are not leak-proof. For e~ample, in U.S.
Patent 5,104, 008 to Crisci, there is disclosed a closure member with a pouring spout which is pulled down over the pouring spout with the hope that in a closed position of the closure member to pouring spout, there is no leakage between the plug and cooperating central opening.

portion, the wall sections 92 of the skirt member 66 contact the lower surface portion of the side wall 64 to drive the skirt member 66 into the tamper-evident mode, i . e ., the crn~ n~r closure member 12 may not now be removed from the c~nt~;n,~r 100 without fracturing the frangible arm members 68. Removal of the crnt:l;ner closure portion from the rr,nt~;nf~r 10 retains the tamper-evident skirt member 66 about the neck portion 102 of the container 100 . ~dditionally, the inwardly ,~rrn~1i n~ lip 106 cooperates with groove 80 of the closure 10 to provide for additional cl,osure- integrity between the closure 10 and the container 100, particularly for uses relating to carbonate beverage bottling.
Conseriuently, after assembly onto a rrnt;l;n~r, rf~nt~;n~r and pouring spout integrity are ensured by the existence of intact frangible elements 68 between the side wall 64 and skirt member 66 of the rrnt;l;nPr closure member 12 and the existence of intact frangible elements 54 between the side wall portion 40 and skirt member 52 o~ the pouring spout closure r '^r 16.
An upward force on lower sur~ace portion of the annular flange 50 of the pouring spout closure member 14, such as by finger pressure, causes the frangible elements 54 to fracture as a result bf contact between the shoulder 62 of the skirt member g _ f~ 21~7~04 ~
52 with the shoulder 38 of the pouring spout 16 thereby cau8ing the skirt member 52 to remain positioned about a lower neck portion of the pouring spout 16. The side wall section 40 of the pourirg spout ~ nt~inf~r member 12 nnntin~ in upward mo~ement until arrested by contact of the shoulder 58 thereof with the annular flange 50 of the pouring spout 16 with concomitant fluid access to the chamber 24 of the pouring spout 16 via the ori~ices 32 and a fluid passage formed between the top surface 30 of the pouring spout 16 and a lower surface o~ the end wall portion 42 of the pouring spout closure member 14 thence through the opening 44 .
Positive closing of the pouring spout closure member 14 on the pouring spout 16 is effected by pushing the pouring spout closure member 14 downwardly on the pouring spout 16 to a point where the shoulder 58 overrides and is positioned in interlocking r~ t;r~n~h;p with shoulder 36 of the pouring spout 16.
Concomitant frictional ,,n~r~ nt exists between the annular ring 46 of the pouring spout closure member 16 within the channel 28 of the pouring spout 16. Data frictional fitting is achie~ed by forming the annular ring 46 of thickness slightly greater, e.g., 0 . 020 mm greater than the width of the annular channel 28 .
~. ~ 21~0~ ~
Once the cnnt~;nPr 100 re~uires refilling, it is necessary to destroy the integrity of the rnnt~;nPr closure member 12 with the rr,nt~;nPr 100 which is e~fected by counterclockwise rotation of the rr,nt;~inPr closure mem~er 12 about the neck portion 102 of the container 100 to a point where the frangible arm members 68 are fractured thereby leaving the tamper-evident ring 66 disposed about the neck portion 102 of the ront~;nPr 100. Turning of the rr,nt;~;nPr closure member 12 about the cnnt~;nPr 100 is rnnt;nllPfl to the point of removal of the closure assembly 10 from the cr~nt~;nPr 100 thereby permitting refilling of the container 100 with any preselected liquid. After refilling, the closure assembly 10 may be repositioned by twisting on the cnnt~;nPr 100 with the pull-push pouring spout closure member 14 cooperating with the pouring spout 16 of the closure assembly as hereinaf ter discussed.
While the present invention has been clescribed in connection with an exemplary ~ t thereof, it will be understood that many modifications will be apparent to those of ordinary skill in the art; and that this application is intended to cover any adaptations or variations thereof. Therefore, it is manifestly ;ntPn~ rl that this invention be only limited by the claims and the equivalents thereof.
