DESCRIPTION OF THE PREFERRED MODALITIES [043] Now with reference in detail to the preferred embodiments of the invention, examples thereof are illustrated in the accompanying drawings. While the invention will be described in conjunction with the preferred embodiments, it will be understood that it is not intended to limit the invention to these embodiments. On the contrary, the invention is intended to cover alternatives, modifications and equivalents that may be included within the spirit and scope of the invention, as described by the appended claims. [044] Turning now to the drawings, where similar components are designated by similar reference numbers throughout the various Figures, it is directed attention to Figures 1 to 4 showing a closure 30 according to the present invention mounted on a container 31. The container 31 is a conventional cardboard box of the type commonly used to distribute and supply beverages, including juice and milk. [045] The closure 30 includes an accessory 32 and a removable and resealable cover 36. As illustrated in FIG.

Figure 3, the accessory 32 is connected to the container 31 in known manner. Although the closure of the present invention is illustrated in combination with a carton, it will be aciated that the closure of the present invention is equally suitable for use with other types of containers including beverage bags, sacks and other visible packaging. In addition, the accessory described here is equally suitable for use with other types of containers and their closures. [046] Suitable materials for the accessory of the present invention, include but are not limited to low density polyethylene, linear low density polyethylene and high density polyethylene, polypropylene and other suitable materials. Suitable materials for the lid of the present invention include, but are not limited to, low density polyethylene, high density polyethylene, polypropylene, polyethylene and other suitable materials.

[047] With reference to Figure 2, the fitting 32 includes an annular spigot flange 37 and a spout neck 38 extending up therefrom. It will be aciated that the terms up and down as well as in and out are not intended to denote vertical and horizontal directions and are simply provided for clarity with reference to the drawings. The annular flange 37 is connected to the container 31 adjacent to an assortment orifice (not shown) by ultrasonic welding, adhesives or other convenient means. As shown in Figure 3, the neck 38 includes an opening defined by an interior wall 41 which, together with the orifice for dispensing the container, allows the contents of the container 31 to be dispensed. Preferably, the neck 38 also includes a coupling structure of external lid in the form of external threads 42 that are provided in an upper portion of the outer wall 43. [048] The lid 36 includes an upper portion 47 and an annular skirt 48 extending from the upper 47, adjacent to a periphery of the upper part, as illustrated in Figure 3. The internal spout coupling structure in the form of internal threads 49 extends inward from an inner wall 52 of the skirt 48. Internal threads 49 cooperate with external threads 42 to selectively detach and reattach the lid 36 with respect to the spout 32. In particular, the cap 36 is removed from the spout 32 by twisting the cap 36 or by screwing the cap 36 in a direction relative to the container 31 and unscrewing the cap 36 of the spout 32. The cap 36 it is reattached with the spout 32 by screwing the cap in the opposite direction with respect to the spout 32 and re-threading the cap 36 in the spout 32. In this way, if the contents of the container are not completely filled, the cap 36 It can be used for reclosure purposes. [049] The co-operating internal and external threads may be in the form of multi-string threads or a single-string thread extending partially or completely around the outer neck wall of the spout. It will be appreciated that the threads may already be continuous or segmented. Alternatively, the external closure treatment structure and the internal spigot coupling structure can take various other forms. For example, quick coupling strips of complementary coupling, instead of complementary threads, may be loaded on the closure and the spout respectively to form the external closure coupling structure and the internal spigot coupling structure for purposes of selectively interconnecting the closure and spit. [050] Preferably, the cap 36 includes a hollow annular plug 53 that is downwardly dependent from a surface interior of the lid 36 adjacent to the intersection of the top 47 and skirt 48, as illustrated in Figure 3. Although the embodiment illustrated shows the annular plug 53 extending from a portion of the lid 36 adjacent to the intersection of the top 47 and the skirt 48, it should be appreciated that the annular plug may extend either from the top or the skirt according to the present invention. [051] Preferably, an interference fit between an outer surface of the cap 53 and an upper portion of the inner wall 41, provides a resealable primary seal for the contents of the container 31. In the illustrated embodiment, the upper portion of the neck 38 includes a seal flange 54 which couples the plug 53 so as to provide a seal for fluid between the fitting 32 and the lid 36. In particular, the neck 38 has a thin wall portion that flares outward and inward to form the seal flange 54. This seal flange configuration 54 allows the seal flange to "yield" and distort to provide a tight interference fit between the seal flange 54 and the cap 53. In particular, the seal flange 54 has an outwardly tapered inner surface, which is complementary to an outer tapered surface of the plug 53. The lid 36 and the accessory 32 are formed of materials that are sufficiently flexible to allow the seal flange 54 to stretch and allow the plug 53 to be compressed enough to be received together and provide a fluid tight seal therebetween. [052] Advantageously, the complementary angled surfaces of the flange seal 54 and the cap 53, as well as the thin wall thickness of the flange seal 54, provide a configuration that provides a better compression fit and / or interference between the seal of flange 54 and cap 53, resulting in an improved fluid seal. [053] It will be appreciated that the plug can be provided in the form of a solid disc projecting from the interior surface of the top 47 as well as other convenient shapes. Alternatively, it will be appreciated that a closure without a plug also falls within the scope of the present invention. In the case where the closure is not provided with a plug, a liner of compressible material can be provided to seal the inner surface of the closure against the seal flange of the spout or alternatively, the flange seal can compress directly against a lower surface of the top part of the lid. [054] With continuous reference to Figures 2 and 3, the spout 32, preferably includes a frangible tamper indicating membrane 63, which seals the opening of tap 32 until a consumer initially opens the container. An outer periphery of the membrane 63 is frangibly connected with an intermediate portion of the inner wall 39 on a weakening line 64 in a well-known manner that allows a consumer to pull and tear the membrane 63 of the spout 32. There will be It will be appreciated that the tamper indicating membrane can be located at a bottom edge of the spout or at any desired location on the bottom edge. In the illustrated embodiment, the accessory 32 includes a weeding coupling structure in the form of a continuous weeding coupling strip 65. The weeding coupling strip 65 is provided to frictionally couple the exterior of an automatic equipment weeding, which is generally used to apply an accessory to a container in a manner similar to that described by the US Patents Nos. 6,129,228, 5,957,312 and 5,915,574, all issued to Adams et al., All the contents of these patents are incorporated herein by reference. [055] Accessory 32 includes a clamping member 69 that is provided in the frangible membrane 63 to allow a user to remove the frangible membrane 63 from the spout neck 38 in a well-known manner. According to the present invention, the clamping member 64 it is specifically adapted to make it easier for a user to grasp and detach the clamping member when the frangible membrane is removed. [056] As illustrated in Figure 2, the clamping member 64 includes a semi-circular segment 70 having first and second terminal ends. A first terminal end 71 is connected to the frangible membrane 63 adjacent the weakening line 64. A second terminal end or free end 74 is located remotely from the first terminal end 71. The second terminal end is a free end where the second terminal end is not connected to the first terminal end, the frangible membrane and any other structure of the accessory. Preferably, the clamping member is monolithically formed with the frangible membrane and the remaining portions of the fitting. [057] A portion of the clamping member 64 extends over an upper edge of the spout neck 38a as illustrated in Figure 3, so as to make it easier for a user to tighten or clamp the clamping member. In particular, a portion of the semi-circular segment 70 extends horizontally and slightly above the upper edge and seal flange 54. This location provides additional space below the semicircular segment 70 and enters the segment 70 and the frangible membrane 63. This location can facilitate a user insert the tip of a finger below the semicircular segment 70 in this manner facilitating a user to remove and hold the member 64 as discussed in more detail below. [058] To further facilitate a user to tighten the clamping member 63, the second terminal end 74 is provided with several outwardly extending ribs 75. It will be appreciated that one or more ribs may be employed in accordance with the present invention . Alternatively, the holding member may be free of these ribs that extend outwardly. Furthermore, it will be appreciated that the fastening member may be provided with a textured surface in order to facilitate a user in holding or tightening the fastening member. [059] In the illustrated embodiment, the clamping member 64 extends approximately 260 degrees on an arcuate path that is substantially concentric with the spout neck 38. The clamping member 64 extends in a defined space on the frangible membrane 63 and inside the interior wall 41 of the spout neck 38. It will be appreciated that a semicircular segment 70 of the fastening member 69 may extend over an arcuate route within the range of approximately 180 degrees, up, although slightly less than approximately 360 degrees. [060] In operation, a consumer will sometimes remove the lid 36 from the accessory 32 and verify that the frangible membrane is intact in order to ensure that the contents of the container 31 have not been tampered with. In order to initially open the container 31, the user will again remove the lid 36 from the accessory 32, if necessary to expose the fastening member 69 located inside the spout neck 38. The user inserts a finger under the semicircular segment 70, so that the user can bend or leverage a portion of the clamping member 64 upwardly from the spout neck 38. Advantageously, the clamping member 64 is flexible and allows the user to straighten the semicircular segment 70 to a certain degree, allowing that the segment better conforms to the contour of the user's finger. Since the semicircular segment 70 has a flat profile, a user can firmly grip the semicircular segment 70 between his index finger and thumb, thereby facilitating the removal of the frangible membrane 63 from the spout neck 38. Once the frangible membrane 63 is removed, the user can then partially or completely fill the contents of the container 31. In the event that a portion of the contents remains inside the container, the user can then reseal the container by screwing the lid 36 back into the accessory 32. [061] In certain aspects, parts of the closure of the present invention discussed above resemble two of the modalities discussed below. Accordingly, similar reference numbers have been used to describe similar components of the illustrated closures of the present invention. [062] In one embodiment, shown in Figures 4-8, a modified accessory 32a includes a modified fastening member in accordance with the present invention. In many other aspects, the structure of the accessory 32a resembles the accessory 32 discussed above. The fitting 32a includes an annular spigot flange 37a and a spout neck 38a extending up therefrom. The neck 38a has a thin wall portion that flares outwardly and upwardly to form a seal flange 54a. A frangible membrane indicating tampering 63a seals the opening of the accessory 32a in the same manner as discussed above. [063] Accessory 32a also includes a weed coupling structure, in the form of projections coupling discrete weeds 76, which are substantially semicircular in shape. In the illustrated embodiment, the accessory and 32a include eight projections of weeding coupling 76, however it will be appreciated that one or more weed coupling projections may be used, in accordance with the present invention. [064] Accessory 32a includes a holding member 69a having inwardly extending ribs 80 in place of the outwardly extending ribs described above. The ribs 80 are provided to improve the fastening of a user in the member 69a. It will be appreciated that the fastening member may include inwardly extending ribs in addition to outwardly extending ribs, in accordance with the present invention. The fastening member 69a also includes a tapered bottom surface 81 that can further facilitate a user to hold and remove the member 69a. [065] The overall structure and appearance of the clamping member 69a is more rounded than the clamping member 69 discussed above. The more rounded appearance has several advantages, including but not limited to increased aesthetics and improved form of demoulding. [066] In one embodiment shown in Figures 9-11, a modified accessory 32b includes another modified fastening member in accordance with the present invention. As shown in Figures 10 and 11, the holding member 69b extends in a helical path that is extends upwards and outwards from the spout neck 38b. The fastening member 69b is molded in its helical form. The fitting 32b is formed of materials that are sufficiently flexible to allow the fastening member 69b to be substantially frictional. In this way, when the fitting 32b is assembled with a lid, the flexibility of the clamping member 69b allows it to flex downwards and be placed within the space defined by a frangible membrane upper surface 63b, inner wall 41b of the spout neck 38b and an inner surface of the upper part of the lid, without damaging the frangible membrane 63b. [067] In one embodiment shown in Figures 12-13, a modified accessory 32c includes another modified fastening member in accordance with the present invention. As shown in Figures 12 and 13, the fastening member 69c includes a straight segment 82 that extends at an arcuate angle with respect to the frangible membrane 63c, i.e. up and out of the spout neck 38c. The clamping member 69c is molded in its straight form at an angle of approximately 30 degrees, with respect to the tangible membrane 63c. It will be appreciated that the fastening member 69c may extend from the frangible membrane at an angle of about 10 degrees to about 60 degrees, and preferably an angle of about 15 degrees. degrees up to about 45 degrees, in accordance with the present invention. [068] The holding member 69c includes a rib 85 that extends substantially perpendicular both from an upper surface and a lower surface of the straight segment 82 adjacent the second or distant term end 74c. It should be appreciated however that a rib may extend from one and / or the other of the upper and lower surfaces of the straight segment, to facilitate fastening by a consumer, in accordance with the present invention. [069] The fitting 32c is formed of materials that are sufficiently flexible to allow the fastening member 69c to flex substantially. In this way, when the fitting 32c is assembled with a lid, the flexibility of the clamping member 69c allows it to flex downwards and locate within the area defined by an upper surface of the frangible membrane 63c, the inner wall 41c of the neck spout 38c, and an inner surface of the upper part of the cap, without damaging the frangible membrane 63c. [070] In one embodiment shown in Figures 14-16, a modified fixture 32 includes another modified fixture member in the form of a clamping ring, a modified seal flange, and a mating projection. weed, according to the present invention. In many other aspects, the structure of the accessory 32d resembles that of the accessories discussed above. [071] In contrast to the above accessories, the accessory 32d includes a clamping ring 86, which is similar in some respects to the conventional release rings found in the previous accessories. The clamping ring 86 includes a circular portion 91 that extends within a substantially horizontal plane. Importantly and in contrast to the previous conventional release rings, a portion of the clamping member 86 extends over the upper edge of the spout neck 38d and the seal flange 54b. This positioning of the clamping ring 86 makes it more accessible and provides additional space below the ring and between the clamping ring 86 and the frangible membrane 63b in a manner similar to the location of the semicircular segment 70, discussed above. Accordingly, said positioning can make it easier for a user to insert the tip of a finger or a fingernail under the clamping ring 86, thereby facilitating the detachment of the clamping ring to the interior of the spout neck 38d, allowing the user to conveniently grip the clamping ring 86 and remove the frangible membrane 63d.

[072] As shown in Figure 15, the seal flange 54d includes a thin-walled section 92 having a substantially uniform wall thickness, being significantly less than the wall thickness of the spout neck 38d. This configuration defines an upper annular seal surface 93 in an upper portion of the spout neck 38, which is placed inwardly of the thin-walled section 92 and substantially below an upper edge of the thin-walled section 92. [073] ] Cover 36d includes an annular cap flange 53d, extending in and down from an interior surface of the skirt 48d adjacent the top 47d. The plug flange 53d has a curved profile that is complementary to that of the thin-walled section 92, as shown in Figure 16. The plug flange 53d and the seal flange 54d are dimensioned and configured to provide an interference between when the lid 36d is threaded onto and engages with the accessory 32d. In addition, a lower edge 96 of the cap flange 53d is dimensioned and configured to abut against the annular seal surface 93 of the spout neck 38d, to provide and / or supplement a fluid tight seal between the cap 36d and the cap. 32d accessory [074] The lid 36d further includes a modified weed coupling structure in the form of grooves that they connect vertically extending weeds 97, which extend radially inward from the inner wall 41d of the spout neck 38d. The weed coupling tabs 97 are provided to frictionally engage the weed outside of the automated equipment in a manner similar to that discussed above. [075] In a embodiment shown in Figures 17-18, a modified accessory 32e includes a modified frangible membrane in accordance with the present invention. In many other aspects, the structure of the accessory 32e resembles that of the accessories discussed above. [076] In contrast to the above embodiments, the frangible membrane 63e has a convex shape, as shown in Figure 18. A portion of the clamping ring 86e extends horizontally on an upper edge of the seal flange 54e in a form similar to the one discussed above. Because the frangible membrane 63e extends downwardly from the clamping ring 86e, the space below the clamping ring is further increased to further facilitate a user to insert the tip of a finger under the clamping ring 86e, in this way facilitating the user to hold and remove the clamping ring 86e. [077] In one embodiment shown in Figures 19-20, a modified accessory 32f includes another seal flange modified according to the present invention. In many other aspects, the structure of the accessory 32f resembles that of the accessories discussed above. [078] The seal flange 53f extends up and out of an upper portion of the spout neck 38f in a similar fashion to the seal flanges of the above embodiments. In this embodiment, however, the only portion of the seal flange 53f having an inner wall thickness other than that of the remaining portions of the spout neck 38f is the portion extending radially outwardly from the outer wall 43f of the neck of the neck. spout 38f, as shown more clearly in Figure 20. The hollow annular plug 53f has an increased wall thickness with respect to the above modes. [079] In one embodiment shown in Figures 21-22, a modified accessory 32g includes a modified spigot and cap, a modified frangible membrane and a modified clamping ring in accordance with the present invention. In many other aspects, the structure of the accessory 32g resembles that of the accessories discussed above. [080] As shown in Figure 22, the spout neck 38g terminates at an upper end with an upper annular seal surface 93g. The lid 36g includes an upper portion 98 having an internal diameter that is more smaller than that of the inner wall 41g of the spout neck 32g. The bottom edge of the upper portion 98 forms a shoulder facing downwardly 102. The shoulder 102 and the seal surface 93g are dimensioned and configured to buttly confine each other when the cap 36g is completely threaded onto the accessory 32g so as to to provide a re-sealable active hermetic seal or to reseal between them. [081] The frangible membrane 63g is frangibly attached on its periphery, with the inner wall 41g adjacent to the upper end of the spout neck 38g, which is immediately adjacent to the upper annular seal surface 93g, as shown in the Figure 22. As in the above embodiments, the frangible membrane 63g is connected to the spout neck 38g on a weakening line 64g. [082] As shown in Figure 22, four frangible connectors 103 interconnect the circular portion 91g of the clamping ring 86g and respective portions of the frangible membrane 63g. The frangible connectors 103 are circumferentially spaced over the circular portion 91g. Although the illustrated embodiment shows four frangible connectors, it will be appreciated that one or more frangible connectors may be used in accordance with the present invention.

[083] Frangible connectors 103 provide additional structural integrity between the clamping ring 86g and the frangible membrane 63g. This additional structural integrity is advantageous in this embodiment because once the cap 36g is removed from the accessory 32g the spout neck 38g offers little protection by a user accidentally twisting or detaching the ring 86g and accidentally tearing a portion of the weakening line 64g. [084] The clamping ring 86g is connected to the frangible membrane 63g adjacent the weakening line 64g and extends, almost entirely over the upper edge of the spout neck 38g and in particular, the upper annular seal surface 93g. The upper portion 98 of the cap 63g forms a deep chamber in order to accommodate the upper profile of the clamping ring 86g. This configuration provides a clamping ring that is substantially not obstructed by the spout neck, thereby facilitating a user to hold and detach the clamping ring. [085] The use and operation of the fittings 32a-g, including the removal of the frangible membranes 63a-g from the spout collars 38a-g, respectively, is similar to that of the accessory 32 discussed above. In particular, a user can hold and remove the clamping member to tear the frangible membrane from the spout neck to open Initially the accessory and allow assortment of the contents of the container to which the accessory is applied. [086] In a embodiment shown in Figures 23-30, a modified accessory 32h includes a modified spigot, a modified frangible membrane and a modified clamping ring, in accordance with the present invention. In many other aspects, the structure of the accessory 32h resembles the accessories discussed above. [087] As shown in Figures 23-25, a tapered lower edge 104 of the clamping member 69h is frangibly connected with an upper edge of the spout neck 38h. In particular, the frangible connection 107 interconnects the lower edge of the circular segment 70h of the fastening member 69h and the upper edge of the spout neck 38h. The frangible connection 107 extends between the first terminal end 71h and the second terminal end 74h. In this embodiment, the frangible connection 107 is in the form of an additional line of weakness extending substantially over the weakening line 64h of the frangible membrane 63h, as illustrated more clearly in Figure 26. [088] In the embodiment illustrated, the circular segment 70h, as well as the frangible connection 107, extend over a majority of the upper edge of the spout neck 38h and the adjacent weakening line 64h. From Preferably, the circular segment 70h extends over the upper edge of the spout neck 38h at least about 270 degrees and in the illustrated embodiment, almost the entire circumference of the spout fluid 38h. For reasons that will be apparent below, the frangible connection 107 extends over the upper edge of the spout neck 38h, by a distance slightly smaller than that of the circular segment 70h. [089] The clamping member 69h is positively connected to the frangible membrane 63h by a connecting frame 108, which is seen more clearly in Figure 27. The connecting frame 108 is a reinforced structure, the thickness of which is substantially the same as the wall thickness of the frangible membrane 63h and the wall thickness of the spout neck 38h. The structure of the connecting frame 108 shown in Figure 27 is much thicker than the thickness of the frangible connection 107 shown in Figure 26. [090] The spigot neck 38h further includes a stop 109 located in the adjacent frangible connection. to the connecting frame 108, as shown more clearly in Figure 28. The purpose of the stop 109 is to prevent and / or prevent propagation over the frangible connection 107 in the connecting frame 108. In the illustrated embodiment, the stop 109 is an opening located in the frangible connection 107 immediately adjacent to the connection frame 108. It will be appreciated that other ways of stop may be used in accordance with the present invention. For example, instead of an opening, the stop can take the form of a projection or other type of wall thickness increased, sized and configured to prevent propagation over the frangible connection in the connection frame. Alternatively, it will be appreciated that if the connection pattern is sufficiently voluminous or thick, this connection pattern may be sufficient to prevent propagation over the frangible connection in the connection frame, without need for a stop. [091] In the illustrated embodiment, the additional lid coupling structure in the form of an additional external lid coupling thread 113 is provided in an outer wall of the circular segment 70h of the clamping member 69h. The additional thread 113 is dimensioned and configured to cooperate with the internal threads 49h of the cap 36h, as illustrated more clearly in Figure 29. [092] In operation and use, a consumer will sometimes remove the cap 36h from the accessory 32h and it will verify that the frangible membrane is intact in order to ensure that the contents of the container, to which the closure 30h has been connected, have not been tampered with. The initial position of the lid 36h with respect to the accessories 32h, is shown in Figure 29. In order to initially open a container to which the closure 30h is connected, the user will again remove the lid 36h from the accessory 32h, in this way exposing the fastening means 69h. The user grasps the second terminal end 74h of the clamping member 69h, such that the user can tear the second terminal end 74h of the spout neck 38h over the frangible connection 107. The user continues to detach the second end 74h and to tear the circular segment 70h over the frangible connection 107, up to the stop opening 109, together with the thickened connecting frame 108, limits further propagation between the clamping member 69h and the upper edge of the spout neck 38h. The detachment force of the user is then transferred to the frangible membrane 63h over the connection frame 108, so that the user can securely hold the circular segment 70h firmly between his index finger and thumb and remove the frangible membrane 73h from the neck of tap 38h. Once the frangible membrane 63h is removed, the user can then partially or completely fill the contents of the container. [093] In the event that a portion of the contents remain inside the container to which the closure 30h is added, the user can then reseal the container by screwing the lid 36h back into the fitting 32h. Because the holding member 69h is no longer connected to the spout neck 38h, the cap 36h can be threaded more, thereby achieving a lower profile of the closure 30h as illustrated in Figure 30.
