DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

FIGS. 1-3 illustrate a package 20 in accordance with one exemplary embodiment of the present disclosure. Package 20 includes a closure 24 secured to a container 22. Container 22 has a body 26 from which a neck finish 28 axially extends. Neck finish 28 preferably is cylindrical and typically is coaxial with body 26, although this need not necessarily be the case. Body 26 may be of any suitable geometry such as cylindrical or rectangular. Neck finish 28 has an open end 30 and an external crown or bead 32. External bead 32 preferably is circumferentially continuous. Container 22 may be made by any suitable technique, and the geometries of FIGS. 1-3, 8-12, 15, 17 and 19-20 are exemplary. Although the closure and package of the present disclosure are particularly suitable for wide-mouth container applications as illustrated in FIGS. 1-3, 8-11 and 19-20, the disclosure also can be implemented in other applications, such as narrow-neck container applications (FIGS. 12-18). Container 22 preferably is of glass construction (FIGS. 1-3, 12, 15, 17 and 19-20), but may be of plastic construction (FIG. 10).

Closure 24 preferably is of one-piece integrally molded plastic construction, and includes a mounting base or ring 34 connected to a lid 36 by a hinge 38. Hinge 38 may be of any suitable type, but preferably is formed by a pair of laterally spaced hinge elements. This lateral spacing between the hinge elements contributes to the stability of lid 36 with respect to ring 34. The specific exemplary hinge 38 illustrated in the drawings is disclosed in U.S. Pat. No. 6,041,477. Other types of hinges, such as single element hinges and film hinges, can be employed. Closure 24 may be of any suitable one-piece integrally molded plastic.

Ring 34 (FIGS. 3-7) is circumferentially continuous and has a circumferentially continuous internal recess 40 that is received by snap fit in assembly over external bead 32 on container neck finish 28. A conical internal surface 42 (FIGS. 3 and 6) on ring 34 cooperates with a conical external surface 44 (FIG. 3) on container neck finish external bead 32 for guiding and resiliently stretching ring 34 onto neck finish 28 until bead 32 is received by snap fit into recess 40. Adjacent to the end of ring 34 remote from surface 42, there is a ledge or shoulder 46 (FIG. 6) that extends radially inwardly from an internal channel 48. A conical surface 50 extends radially and axially from a position adjacent to channel 48 for purposes to be described.

Lid 36 has a base wall 52 and a peripheral skirt 54. Skirt 54 preferably is circumferentially continuous except as hinge 38. At the free edge of skirt 54 spaced from base wall 52 there is a conical surface 56 (FIG. 7) that extends radially inwardly and axially away from base wall 52. Conical surface 56 terminates at a circumferential external bead 58. Bead 58 preferably is circumferentially continuous except at hinge 38 and latch 60. Latch 60 is provided on lid 36, preferably at a position diametrically spaced from hinge 38. Latch 60 extends from skirt 54 of lid 36, and is adapted to engage a corresponding latch element 62 on ring 34 diametrically spaced from hinge 38. Latch 60 and latch element 62 may be of any suitable type, being illustrated only schematically in the drawings.

A foil seal 64 (FIGS. 2-3) may be received over the open end 30 of container finish 28. Foil seal 64 may comprise a suitable disk, such as a multilayer disk having adjacent metal and plastic layers for induction heat-sealing securement of seal 64 to the end of the container finish.

In use, closure 24 is secured to container neck finish 28 either before or after filling the container with product. Container 22 can be filled with product and seal 64 secured to end 30 of container neck finish 28 before securement of closure 24. Closure 24 can be secured to container neck finish 28 by urging mounting ring 34 along surface 44 of bead 32 resiliently to expand the ring until the ring snaps over bead 32. This securement of ring 34 to bead 32 may be accomplished with lid 36 open or, more preferably, closed. To open lid 36 and dispense product, a user's thumb is positioned beneath latch 60 and lid 36 is pushed upwardly (in the orientation of FIGS. 1-3). Foil seal 64 then is removed from container neck finish 28, which provides a tamper indication that the package has been opened. After product has been dispensed from the package, lid 36 is pivoted toward the closed position. As the lid approaches the closed position, bead 58 on lid skirt 54 engages surface 50 on ring 34 to center lid 36 with respect to mounting ring 34. Further downward pressure on lid 36 snaps bead 58 into channel 48, so that the lid is secured to the mounting ring by snap fit and the edge of skirt 54 engages shoulder 46 on ring 34. Conical surfaces 50, 56 are in facing engagement with each other. Because ring 34 is disposed beneath the end of neck finish 28 in this embodiment (FIG. 3), the inside edge of lid skirt 54 engages the outside edge of surface 44 so that skirt 54 is captured between surface 44 and ring 34. This contributes to the stability of the closure on the container. Bead 58 cooperates with channel 48 to provide a seal when the lid is in the closed position.

FIGS. 8 and 9 illustrate a package 66 in accordance with a second exemplary embodiment of the disclosure. Reference numerals employed in FIGS. 8 and 9 (and FIGS. 10-25) that are identical with those employed in FIGS. 1-7 illustrate correspondingly identical or related components. The primary difference between the package of FIGS. 8-9 and the package of FIGS. 1-7 is that the neck finish 68 of container 70 has a pair of axially spaced external beads 72, 74. In the particular embodiment illustrated in FIG. 9, lower bead 74 has a greater outside diameter than upper bead 72. Mounting ring 34 is received by snap-fit over lower bead 74. The internal surface of skirt 54 on lid 36 engages the radially outer edge of upper bead 72 in the closed position of lid 36, as illustrated in FIG. 9. In this way, bead 72 cooperates with lid 36 to stabilize the lid in the closed position of the package and to center the lid during closure. Container 70 preferably is of glass construction (FIGS. 8-9), but may be of plastic construction (FIG. 11).

FIG. 12 illustrates a package 80 in accordance with a further embodiment of the disclosure. Package 80 includes a container 82 having a narrow-neck finish 84 with an external crown or bead 32. A closure 86 includes a base or ring 88 with an external flange or skirt 90 having an internal bead 94 forming recess 40 received by snap fit over external bead 32 on neck finish 84. Closure ring 88 also has a deck 96, preferably flat and annular, that is received against the end of neck finish 84. An annular pour lip 97 has an inner portion 98 that extends from deck 96 and is received within neck finish 84, and an outer portion 100 that extends from inner portion 98 and deck 96. Closure 86 also includes a lid 102 connected by hinge 38 to ring 88 for movement between an open position illustrated in FIG. 12 and a closed position overlying deck 96 and external portion 100 of pour lip 97. Lid 102 has in internal bead 104 adapted to be received by snap-fit over an external bead 106 on ring 88 adjacent to deck 96 to hold lid 102 in the closed position.

FIGS. 13 and 14 illustrate a closure 110 that is a modification to closure 86 in FIG. 12. In closure 110, there is a tube 112 integrally mounted within the inner portion 98 of pour lip 97 by means of angularly spaced radially extending spokes 114. Tube 112 vents air into the package as product flows between spokes 114 when the package is tilted for dispensing. As shown in FIG. 14, bead 94 in the ring 116 of closure 110 (and bead 94 in ring 88 of closure 86 in FIG. 12) preferably is buttressed by a plurality of angularly spaced gussets 118. Gussets 118 both assist application of closure 116 (and closure 88) to the container neck finish, and resist distortion of flange 90 and thereby help prevent unintentional removal of the closure from the container neck finish.

FIG. 15 illustrates a package 120 that includes a closure 122 (FIGS. 15 and 16) applied to the neck finish 126 of a container 124. Closure 122 includes a base or ring 128 received by snap-fit over the external bead 90 on the container neck finish as previously described. A lid 130 is coupled to base 128 by a hinge 38. Ring 128 has an external skirt or flange 132 with internal bead 94 and a deck 134 with a dispensing opening 136 surrounded by an annular wall 138. Lid 130 has an outer peripheral skirt 140 and an inner protrusion 142 for sealing dispensing opening 136 in the closed position of the lid. Protrusion 142 in FIGS. 15 and 16 comprises an annular wall that externally engages annular wall 138 above deck 134 when lid 130 is closed (FIG. 15). Skirt 140 of lid 130 and skirt 132 of ring 128 have polygonal geometries that align with each other in the closed position of the lid (FIG. 15). In the embodiment of FIGS. 15 and 16 (and the embodiment of FIGS. 17 and 18), these geometries are octagonal. In the embodiment of FIGS. 15 and 16, a corner 143 of the polygonal geometry of ring 128 is disposed opposite hinge 38, and a corner 144 of lid 130 is disposed opposite the hinge. A thumb recess 146 on skirt 132 at corner 143 enables corner 144 of lid 130 to be used for opening the lid. Package 148 and closure 150 in the embodiment of FIGS. 17-18 are similar to package 120 and closure 122 in FIGS. 15-16 except that a flat section 152 of skirt 153 on ring 154 is disposed opposite hinge 38, and a flat section 156 on the skirt 158 of lid 160 is disposed opposite hinge 38. A thumb tab 162 extends outwardly from flat skirt section 156 to overlie flat skirt section 152 on ring 154 for opening the lid.

FIGS. 19-20 illustrate a package 170 that includes a closure 172 applied to the neck finish 68 of a container 70. Container 70 is similar to that illustrated in FIGS. 8 and 9. Closure 172 includes a base or ring 174 having a recess 176, formed in part by a snap bead 178, received over ring 74 on neck finish 68. A lid 180 is integrally connected to ring 174 by a hinge 38 as previously described. Lid 180 has a peripheral skirt 182 that is received by snap-fit against ring 174 as previously described. In this embodiment, a seal disk 184 is captured on lid 180 between an internal bead 186 that extends around skirt 182 and a plurality of ribs or other support structures 188 that extend from the underside of the base wall 190 of lid 180. Thus, ribs 188 press disk 184 into sealing engagement with the end of container neck finish 68 when lid 180 is closed, and bead 186 on lid skirt 182 lifts seal disk 184 off of the end of the container neck finish as the lid is opened. Bead 186 may be circumferentially continuous or discontinuous.

FIGS. 21-25 illustrate a feature than can be implemented in closure 172 (FIGS. 19-20) to help align lid 172 with ring 174 as lid 172 is pivoted toward the closed position. Either the lid 172 or ring 174 (lid 172 in the illustrated embodiment) has at least one notch 192, and preferably a plurality of angularly spaced notches 192 around its periphery. The other element (ring 174 in the illustrated embodiment) has at least one lug 194, and preferably a plurality of angularly spaced lugs 194. As lid 172 is moved to the closed position over ring 174, lugs 194 align with notches 192, as shown in FIG. 25, to align lid 172 with ring 174 both circumferentially and laterally. This feature is particularly useful in conjunction with closures of large diameter adapted for use in conjunction with wide-mouth containers.

There thus have been disclosed a plastic closure for a container, particularly a glass container, and a plastic-closure/glass-container package that fully satisfy all of the objects and aims previously set forth. The neck finish of the container has a reduced overall height as compared with prior art constructions having threads or the like for mounting a closure on the container and/or having tamper-indicating means on the container neck finish beneath the thread or crown for mounting the closure. The package of the present disclosure can increase closure application speeds while reducing closure application issues. The closure is a low-profile closure. The exemplary embodiments provide sealing between the closure and the container neck finish, and the preferred laterally spaced hinge element construction provides stability between the closure lid and the closure base.

The disclosure has been presented in conjunction with two presently preferred embodiments, and a number of additional modifications and variations have been described. Other modifications and variations readily will suggest themselves to persons of ordinary skill in the art in view of the foregoing discussion. For example, the exemplary disclosed embodiments are free to rotate around the axis of the container neck finish. However, the closure could be made non-rotatable on the container neck finish, such as by providing internal lugs on ring 34 that are received in external recesses on bead 32 or 74, without departing from the disclosure in its broadest aspects. The disclosure is intended to embrace all such modifications and variations as fall within the spirit and broad scope of the appended claims.
