- Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. While the invention will be described in conjunction with the preferred embodiments, it will be understood that they are not intended to limit the invention to those embodiments. On the contrary, the invention is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the invention as defined by the appended claims.
- Turning now to the drawings, wherein like components are designated by like reference numerals throughout the various figures, attention is directed to FIGS.1-4 which show a
closure 30 in accordance with the present invention mounted upon acontainer 31.Container 31 is a conventional paperboard carton of the type commonly used for distributing and dispensing beverages, including juice and milk. -
Closure 30 includes afitment 32 and a removable andresealable cap 36. As shown in FIG. 2,fitment 32 is attached tocontainer 31 in a known manner. Although the closure of the present invention is illustrated in combination with a paperboard carton, one should appreciate that closure of the present invention is equally suited for use with other types of containers including beverage bags, sacks, and other flexible packaging. Furthermore, the fitment described herein is equally suited for use with other types of containers and closures therefore. - Suitable materials for the fitment of the present invention include, but are not limited to, low density polyethylene, linear low density polyethylene, high density polyethylene, polypropylene, and other suitable materials. Suitable materials for the cap of the present invention include, but are not limited to, low density polyethylene, high density polyethylene, polypropylene, polystyrene, and other suitable materials.
- Referring to FIG. 2,
fitment 32 includes anannular spout flange 37 and aspout neck 38 extending upward therefrom. On should appreciate that the terms upward and downward as well as inward and outward are not intended to denote vertical or horizontal directions and are merely provided for clarity with reference to the drawings.Annular flange 37 is attached tocontainer 31 adjacent a dispensing hole (not shown) thereof by ultrasonically welding, adhesives, or other suitable means. As shown in FIG. 3,neck 38 includes an opening defined by aninner wall 41 thereof that, together with the container dispensing hole, allows dispensing of the contents ofcontainer 31. Preferably,neck 38 also includes an external cap engaging structure in the form ofexternal threads 42 provided on an upper portion ofouter wall 43. -
Cap 36 includes a top 47 and anannular skirt 48 extending downward from from top 47 adjacent a periphery of the top, as shown in FIG. 3. Internal spout-engaging structure in the form ofinternal threads 49 extend inward from an inner wall 52 ofskirt 48.Internal threads 49 cooperate withexternal threads 42 to selectively disengage and reengagecap 36 with respect to spout 32. In particular, cap 36 is removed fromspout 32 by twistingcap 36 in one direction relative tocontainer 31 andunthreading cap 36 fromspout 32.Cap 36 is reengaged withspout 32 by twisting the cap in the opposite direction relative to spout 32 andre-threading cap 36 ontospout 32. Thus, if the contents of the container are not completely dispensed,cap 36 may be used for reclosure purposes. - The cooperating internal and external threads may be in the form of multi-lead threads or a single lead thread extending partially or completely around the outer neck wall of the spout. One should also appreciate that the threads may be either continuous or segmented. Alternatively, the external closure-engaging structure and the internal spout-engaging structure may take various other forms. For example, complementary interengaging snap beads, instead of complementary threads, can be located on the closure and the spout respectively to form the external closure-engaging structure and the internal spout-engaging structure for the purpose of selectively interengaging the closure and the spout.
- Preferably,
cap 36 includes a hollowannular plug 53 depending downwardly from an inner surface ofcap 36 adjacent the intersection of top 47 andskirt 48, as shown in FIG. 3. Although the illustrated embodiment showsannular plug 53 as extending from a portion ofcap 36 adjacent the intersection of top 47 andskirt 48, one should appreciate that the annular plug can extend from either the top or the skirt in accordance with the present invention. - Preferably, an interference fit between an outer surface of
plug 53 and an upper portion ofinner wall 41 provide a resealable primary seal for the contents ofcontainer 31. In the illustrated embodiment, the upper portion ofneck 38 includes a sealingflange 54 which engagesplug 53 in order to provide a fluid seal betweenfitment 32 andcap 36. In particular,neck 38 has a thin-walled portion which flares outwardly and inwardly to form sealingflange 54. Such a configuration of sealingflange 54 allows the sealing flange to “give” and distort to provide a tight interference fit between sealingflange 54 and plug 53. In particular, sealingflange 54 has an outwardly tapered inner surface which is complementary to an inwardly tapered outer surface ofplug 53.Cap 36 andfitment 32 are formed of materials that are flexible enough to allow the sealingflange 54 to stretch and to allowplug 53 to compress sufficiently to receive one another and provide a fluid tight seal therebetween. - Advantageously, the complementary angled surfaces of
flange seal 54 and plug 53, as well as the thinned wall thickness offlange seal 54, provide a configuration which provides a better interference and/or compression fit betweenflange seal 54 and plug 53 resulting in an improved fluid seal. - One should appreciate that the plug may be provided in the form of a solid disk projecting from the inner surface of top47 as well as other suitable forms. Alternatively, one should appreciate that a closure without a plug also falls within the scope of the present invention. In the event that the closure is not provided with a plug, a liner of compressible material may be provided to seal the inner surface of the closure against the sealing flange of the spout or, alternatively, the flange seal may compress directly against a lower surface of the cap top.
- With continued reference to FIGS. 2 and 3, spout32 preferably includes a tamper-indicating
frangible membrane 63 which seals the opening ofspout 32 until a consumer initially opens the container. An outer periphery ofmembrane 63 is frangibly connected to an intermediate portion of inner wall 39 along a line ofweakness 64 in a well known manner which allows a consumer to pull and tearmembrane 63 fromspout 32. One should appreciate that the tamper-indicating membrane may be located at a bottom edge of the spout or at any desired location above said bottom edge. In the illustrated embodiment,fitment 32 includes a spud-engaging structure in the form of a continuous spud-engagingbead 65. Spud-engagingbead 65 is provided to frictionally engage the exterior of a spud of automatic equipment which is generally used to apply a fitment to a container in a manner similar to that disclosed by U.S. Pat. Nos. 6,129,228, 5,957,312 and 5,915,574, all to Adams et al., the entire contents of which patents are incorporated herein by this reference. -
Fitment 32 includes a grippingmember 69 which is provided onfrangible membrane 63 to allow a user to removefrangible membrane 63 fromspout neck 38 in a well known manner. In accordance with present invention, grippingmember 64 is specifically adapted to facilitate a user in gripping and pulling the gripping member when removing frangible membrane. - As shown in FIG. 2, gripping
member 64 includes a semicircular segment 70 which has first and second terminal ends. A firstterminal end 71 is connected tofrangible membrane 63 adjacent line ofweakness 64. Second terminal end orfree end 74 is remotely located from firstterminal end 71. The second terminal end is a free end in that the second terminal end is not connected to the first terminal end, the frangible membrane nor any other structure of the fitment. Preferably, the gripping member is monolithically formed with the frangible membrane and the remaining portions of the fitment. - A portion of gripping
member 64 extends above an upper edge ofspout neck 38 a as shown in FIG. 3 in such a manner that it may facilitate a user in clenching or grasping the gripping member. In particular, a portion of semicircular segment 70 extends horizontally and slightly above the upper edge of sealingflange 54. Such positioning provides additional space below semicircular segment 70 and between segment 70 andfrangible membrane 63. Such positioning may facilitate a user in inserting a fingertip below semicircular segment 70 thus facilitating a user in pulling and grippingmember 64 as discussed in greater detail below. - To further facilitate a user in clenching gripping
member 63, secondterminal end 74 is provided with several outwardly extending ribs 75. One should appreciate that one or more ribs may be used in accordance with present invention. Alternatively, the gripping member may be free of such outwardly extending ribs. One should further appreciate, that the gripping member may be provided with a textured surface in order to facilitate a user in grasping or clenching the gripping member. - In the illustrated embodiment, gripping
member 64 extends approximately 270° along an arcuate path which is substantially concentric withspout neck 38. Grippingmember 64 extends in a space defined abovefrangible membrane 63 and withininner wall 41 ofspout neck 38. One should appreciate that a semicircular segment 70 of grippingmember 69 may extend along an arcuate path within the range of approximately 180° up to but slightly less than approximately 360°. - In operation an use, a consumer will sometimes remove
cap 36 fromfitment 32 and verify that frangible membrane is intact in order to ensure that the contents ofcontainer 31 have not been tampered with. In order to initiallyopen container 31, the user will again removecap 36 fromfitment 32, if necessary, to expose grippingmember 69 located withinspout neck 38. The user inserts a finger under semicircular segment 70 in such a manner that the user can bend or pry a portion of grippingmember 64 upward fromspout neck 38. Advantageously, grippingmember 64 is flexible and allows the user to straighten semicircular segment 70 to some degree allowing the segment to better confirm to the contour of the user's finger. As semicircular segment 70 has a flat profile, a user can securely grip semicircular segment 70 firmly between his or her index finger and thumb thus facilitating the removal offrangible membrane 63 fromspout neck 38. Oncefrangible membrane 63 is removed, the user may then partially or wholly dispense the contents ofcontainer 31. In the event that a portion of the contents remains within the container, the user may then reseal the container by threadingcap 36 back ontofitment 32. - In some respects, parts of the closure of the present invention discussed above resemble those of the embodiments discussed below. Accordingly, like reference numerals have been used to describe like components of the illustrated closures of the present invention.
- In one embodiment shown in FIGS.4-8, a modified
fitment 32 a includes a modified gripping member in accordance with the present invention. In many other respects, the structure offitment 32 a resembles that offitment 32 discussed above.Fitment 32 a includes anannular spout flange 37 a and aspout neck 38 a extending upwardly therefrom.Neck 38 a has a thin-walled portion which flares outwardly and upwardly to form a sealingflange 54 a. A tamper-indicatingfrangible membrane 63 a seals the opening offitment 32 a in the same manner as discussed above. -
Fitment 32 a also includes a spud-engaging structure in the form of discrete spud-engagingprotrusions 76 which are substantially semicircular in shape. In the illustrated embodiment, fitment and 32 a includes eight spud-engagingprotrusions 76, however, one should appreciate that one or more spud-engaging protrusions may be utilized in accordance with present invention. -
Fitment 32 a includes a gripping member 69 a having inwardly extendingribs 80 instead of the outwardly extending ribs described above.Ribs 80 are provided to improve a user's grip on member 69 a. One should appreciate that the gripping member can include inwardly extending ribs in addition to outwardly extending ribs in accordance with the present invention. Gripping member 69 a also includes a taperedbottom surface 81 which may further facilitate a user in gripping and pulling member 69 a. - The general structure and appearance of gripping member69 a is more rounded than that of gripping
member 69 discussed above. The more rounded appearance has several advantages including, but not limited to, increased aesthetics and an improved de-molding shape. - In one embodiment shown in FIGS.9-11, a modified fitment 32 b includes another modified gripping member in accordance with the present invention. As shown in FIGS. 10 and 11, gripping member 69 b extends in a helical path extending upward and outward from spout neck 38 b. Gripping member 69 b is molded in its helical shape. Fitment 32 b is formed of materials that are flexible enough to allow gripping member 69 b to flex substantially. Thus, when fitment 32 b is assembled with a cap, the flexibility of gripping member 69 b allows it to flex downwardly and position itself within the space defined by an upper surface of frangible membrane 63 b, inner wall 41 b of spout neck 38 b, and an inner surface of the top of the cap without damaging frangible membrane 63 b.
- In one embodiment shown in FIGS.12-13, a modified
fitment 32 c includes another modified gripping member in accordance with the present invention. As shown in FIGS. 12 and 13, grippingmember 69 c includes astraight segment 82 which extends at an arcuate angle with respect tofrangible membrane 63 c, namely, upwardly and outwardly fromspout neck 38 c. Grippingmember 69 c is molded in its straight shape at an angle of approximately 30° with respect tofrangible membrane 63 c. One should appreciate that grippingmember 69 c can extend from frangible membrane at an angle of approximately 10° to approximately 60°, and preferably at an angle of approximately 15° to approximately 45° in accordance with the present invention. - Gripping
member 69 c includes arib 85 which extends substantially perpendicular from both an upper surface and a lower surface ofstraight segment 82 adjacent the distal or second terminal end 74 c. One should appreciate, however, that a rib can extend from one and/or the other of the upper and lower surfaces of the straight segment to facilitate gripping by a consumer in accordance with the present invention. -
Fitment 32 c is formed of materials that are flexible enough to allow grippingmember 69 c to flex substantially. Thus, whenfitment 32 c is assembled with a cap, the flexibility of grippingmember 69 c allows it to flex downwardly and position itself within the area defined by an upper surface offrangible membrane 63 c, inner wall 41 c ofspout neck 38 c, and an inner surface of the top of the cap without damagingfrangible membrane 63 c. - In one embodiment shown in FIGS.14-16, a modified
fitment 32 d includes another modified gripping member in the form of a gripping ring, a modified sealing flange, and spud-engaging projections in accordance with present invention. In many other respects, the structure offitment 32 d resembles that of the fitments discussed above. - In contrast to the above fitments,
fitment 32 d includes agripping ring 86 which is similar in some aspects to conventional pull rings found on prior fitments. Grippingring 86 includes acircular portion 91 that extends within a substantially horizontal plane. Importantly and in contrast to prior conventional pull rings, a portion of grippingring 86 extends above the top edge of spout neck 38 d and sealingflange 54 d. Such positioning of thegripping ring 86 makes it more accessible and provides additional space below the ring and between grippingring 86 andfrangible membrane 63 d in a similar manner as the positioning of semicircular segment 70 discussed above. Accordingly, such positioning may facilitate a user in inserting a fingertip or a fingernail below grippingring 86 thus facilitating pulling gripping ring up from the interior of spout neck 38 d allowing the user to conveniently grasp grippingring 86 and removefrangible membrane 63 d. - As shown in FIG. 15, sealing
flange 54 d includes a thin-wall section 92 that has a substantially uniform wall thickness that is significantly less than the wall thickness of spout neck 38 d. Such configuration defines a upperannular sealing surface 93 on an upper portion ofspout neck 38 which is disposed inwardly of thin-wall section 92 and substantially below an upper edge of thin-wall section 92. -
Cap 36 d includes an annular plug flange 53 d which extends inwardly and downwardly from an inner surface of skirt 48 d adjacent top 47 d. Plug flange 53 d has a curved profile that is complementary to that of thin-wall section 92, as is shown in FIG. 16. Plug flange 53 d and sealingflange 54 d are dimensioned and configured to provide an interference therebetween whencap 36 d is screwed onto and engaged withfitment 32 d. Furthermore, alower edge 96 of plug flange 53 d is dimensioned and configured to abut against annular sealingsurface 93 of spout neck 38 d to provide and/or supplement a fluid-tight seal betweencap 36 d andfitment 32 d. -
Cap 36 d further includes a modified spud-engaging structure in the form of vertically extending spud-engagingsplines 97 which extend radially inwardly from inner wall 41 d of spout neck 38 d. Spud-engagingsplines 97 are provided to frictionally engage the exterior of the spud of automatic equipment in a manner similar to that discussed above. - In one embodiment shown in FIGS.17-18, a modified
fitment 32 e includes a modified frangible membrane in accordance with present invention. In many other respects, the structure offitment 32 e resembles that of the fitments discussed above. - In contrast to the above embodiments,
frangible membrane 63 e has a convex shape, as shown in FIG. 18. A portion of gripping ring 86 e horizontally extends above an upper edge of sealingflange 54 e in a manner similar to that discussed above. Becausefrangible membrane 63 e extends downwardly from gripping ring 86 e, the space below gripping ring is further increased to further facilitate a user in inserting a fingertip below gripping ring 86 e thus facilitating the user in gripping and pulling gripping ring 86 e. - In one embodiment shown in FIGS.19-20, a modified fitment 32 f includes another modified sealing flange in accordance with present invention. In many other respects, the structure of fitment 32 f resembles that of the fitments discussed above.
- Sealing flange53 f extends upwardly and outwardly from a upper portion of spout neck 38 f in a similar manner as the sealing flanges of the above embodiments. In this embodiment, however, the only portion of sealing flange 53 f that has a thinner wall thickness than that of the remaining portions of spout neck 38 f is the portion which extends radially outward of outer wall 43 f of spout neck 38 f, as most clearly shown in FIG. 20. Hollow annular plug 53 f has an increased wall thickness with respect to that of the above embodiments.
- In one embodiment shown in FIGS.21-22, a modified
fitment 32 g includes a modified spout and cap, a modified frangible membrane and a modified gripping ring in accordance with present invention. In many other respects, the structure offitment 32 g resembles that of the fitments discussed above. - As shown in FIG. 22, spout neck38 g terminates at an upper end thereof with an upper annular sealing surface 93 g. Cap 36 g includes an
upper portion 98 having a smaller inside diameter than that of inner wall 41 g of spout neck 38 g. The bottom edge ofupper portion 98 forms a downward facingshoulder 102.Shoulder 102 and sealing surface 93 g are dimensioned and configured to abut against one another when cap 36 g is fully threaded ontofitment 32 g in order to provide a resealable fluid-tight seal therebetween. - Frangible membrane63 g is frangibly joined along its periphery to inner wall 41 g adjacent the upper end of spout neck 38 g, that is immediately adjacent upper annular sealing surface 93 g, as shown in FIG. 22. As in the above embodiments, frangible membrane 63 g is attached to spout neck 38 g along a line of weakness 64 g.
- As shown in FIG. 22, four
frangible connectors 103 interconnectcircular portion 91 g of gripping ring 86 g and respective portions of frangible membrane 63 g.Frangible connectors 103 are circumferentially spaced alongcircular portion 91 g. Although the illustrated embodiment shows four frangible connectors, one should appreciate that one or more frangible connectors can be utilized in accordance with the present invention. -
Frangible connectors 103 provide additional structural integrity between gripping ring 86 g and frangible membrane 63 g. Such additional structural integrity is advantageous in this embodiment because, once cap 36 g is removed fromfitment 32 g, spout neck 38 g offers little protection from a user inadvertently twisting or pulling ring 86 g and accidently tearing a portion of line of weakness 64 g. - Gripping ring86 g is connected to frangible membrane 63 g adjacent line of weakness 64 g and extends, almost entirely, above the upper edge of spout neck 38 g and, in particular, upper annular sealing surface 93 g.
Upper portion 98 of cap 63 g forms a deep chamber in order to accommodate the higher profile of gripping ring 86 g. Such configuration provides a gripping ring which is substantially unobstructed by the spout neck thereby facilitating a user in grasping and pulling the gripping ring. - The use and operation of
fitments 32 a-g, including the removal offrangible membranes 63 a-g fromspout necks 38 a-g, respectively, are similar to that offitment 32 discussed above. In particular, a user may grip and pull the gripping member to tear the frangible membrane from the spout neck to initially open the fitment and allow dispensing of the contents of the container to which the fitment is applied. - In one embodiment shown in FIGS.23-30, a modified
fitment 32 h includes a modified spout, a modified frangible membrane and a modified gripping ring in accordance with present invention. In many other respects, the structure offitment 32 h resembles that of the fitments discussed above. - As shown in the FIGS.23-25, a tapered
lower edge 104 of grippingmember 69 h is frangibly connected to an upper edge ofspout neck 38 h. In particular,frangible connection 107 interconnects the lower edge ofcircular segment 70 h of grippingmember 69 h and the upper edge ofspout neck 38 h.Frangible connection 107 extends between firstterminal end 71 h and secondterminal end 74 h. In this embodiment,frangible connection 107 is in the form of an additional line of weakness which extends substantially along line of weakness 64 h offrangible membrane 63 h, as most clearly shown in FIG. 26. - In the illustrated embodiment,
circular segment 70 h, as well asfrangible connection 107, extends along a majority of the upper edge ofspout neck 38 h and adjacent line of weakness 64 h. Preferably,circular segment 70 h extends along the upper edge ofspout neck 38 h at least approximately 270 degrees, and in the illustrated embodiment, nearly the entire circumference ofspout neck 38 h. For reasons that will become apparent below,frangible connection 107 extends along the upper edge ofspout neck 38 h for a distance slightly less than that ofcircular segment 70 h. - Gripping
member 69 h is positively attached tofrangible membrane 63 h by a connectingweb 108, most clearly seen in FIG. 27. Connectingweb 108 is a reinforced structure, the thickness of which is substantially the same as the wall thickness offrangible membrane 63 h and the wall thickness ofspout neck 38 h. The structure of connectingweb 108 shown in FIG. 27 is much thicker than the thickness offrangible connection 107 shown in FIG. 26. -
Spout neck 38 h further includes astop 109 located in the frangible connection adjacent connectingweb 108, as most clearly shown in FIG. 28. The purpose ofstop 109 is to prevent and/or prohibit propagation alongfrangible connection 107 into connectingweb 108. In the illustrated embodiment, stop 109 is an aperture located infrangible connection 107 immediately adjacent connectingweb 108. One should appreciate that other forms of stops can be utilized in accordance with present invention. For example, instead of an aperture, the stop may take the form of a protrusion or other type of increased wall thickness dimensioned and configured to prevent propagation along the frangible connection into the connecting web. Alternatively, one should appreciate that if the connecting web sufficiently bulky or thick, such connecting web may be sufficient to prevent propagation along the frangible connection into the connecting web without the need for a stop. - In the illustrated embodiment, additional cap-engaging structure in the form of an additional external cap-engaging
thread 113 is provided on an outer wall ofcircular segment 70 h of grippingmember 69 h.Additional thread 113 is dimensioned and configured to cooperate withinternal threads 49 h ofcap 36 h, as most clearly shown in FIG. 29. - In operation and use, a consumer will sometimes remove
cap 36 h fromfitment 32 h and verify that frangible membrane is intact in order to ensure that the contents of a container, to whichclosure 30 h has been attached, have not been tampered with. The initial position ofcap 36 h with respect tofitment 32 h is shown in FIG. 29. In order to initially open a container to whichclosure 30 h is attached, the user will again removecap 36 h fromfitment 32 h thereby exposing grippingmember 69 h. The user grips secondterminal end 74 h of grippingmember 69 h in such a manner that the user can tear secondterminal end 74 h fromspout neck 38 h alongfrangible connection 107. The user continues to pull secondterminal end 74 h and to tearcircular segment 70 h alongfrangible connection 107 untilstop aperture 109, together with the thickened connectingweb 108, limits further propagation between grippingmember 69 h and the upper edge ofspout neck 38 h. The user's pulling force is then transferred tofrangible membrane 63 h along connectingweb 108 such that the user can securely gripcircular segment 70 h firmly between his or her index finger and thumb and removefrangible membrane 63 h fromspout neck 38 h. Oncefrangible membrane 63 h is removed, the user may then partially or wholly dispense the contents of the container. - In the event that a portion of the contents remains within the container to which
closure 30 h is attached, the user may then reseal the container by threadingcap 36 h back ontofitment 32 h. Because grippingmember 69 h is no longer attached to spoutneck 38 h, thecap 36 h can be screwed down further thus achieving a lower profile ofclosure 30 h as shown in FIG. 30. - For convenience in explanation and accurate definition in the appended claims, the terms “up” or “upper”, “down” or “lower”, “inside” and “outside” are used to describe features of the present invention with reference to the positions of such features as displayed in the figures.
- In many respects the modifications of the various figures resemble those of preceding modifications and the same reference numerals followed by subscripts a, b, c, d, e, f, g and h designate corresponding parts.
- The foregoing descriptions of specific embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and its practical application, to thereby enable others skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the Claims appended hereto and their equivalents.
