- FIGS. 1-10 illustrate one embodiment of a lid of the present invention. As shown in FIGS. 1 and 2, the present invention may be utilized with a
cylindrical beverage container 10. Thecontainer 10 includes an opentop end 12, a closedbottom end 14, and asurrounding side wall 16 therebetween. The opentop end 12 is defined by an annular rim or lip 18 (see FIG. 2) of thecontainer 10. Thecontainer 10 used may be made in a variety of shapes and sizes which may correspond to different shapes and sizes of lids of the present invention. More particularly, theannular rim 18 generally has a predetermined dimension or diameter that is coordinated with the dimension or diameter of thelid 20, as described below. Thebeverage container 10 may be comprised of a variety of materials, including, but not limited to, a plastic material, Styrofoam, or a paper material. - The
lid 20 is adapted for releasably sealably engaging with thetop end 12 of thebeverage container 10. Referring to FIGS. 1-3, the illustratedlid 20 is generally circular in shape. Thelid 20 may be comprised of any shape that corresponds to thetop end 12 of thecontainer 10. Similar to thecontainer 10, thelid 20 may be made in a variety of sizes to accommodate a variety of differentlysized containers 10. Thelid 20 may also be designed to be used with different styles ofcontainers 10. Thelid 20 may be comprised of a variety of materials, including, but not limited to, plastic or composite material. - Referring to FIGS. 1-6, the
lid 20 includes at least atop wall 24 and an annular mountingportion 30 that surrounds a periphery of thetop wall 24. Thelid 20 is secured in place on thecontainer 10 by the mountingportion 30 engaging theannular rim 18 of thecontainer 10. The mountingportion 30 includes an annular, downwardly extending side wall orskirt 28 that forms the outer peripheral circumference of thelid 20, and aninner wall 29. The mountingportion 30 and itswalls portion 30 is capable of engaging theannular rim 18 of thecontainer 10. - As shown in FIGS. 1-3, a
portion 40 of thelid 20 may be torn back (hereafter “the tear-back portion 40”) to provide an opening 34 (see FIG. 2) in thelid 20 to enable drinking from thecontainer 10 without removal of thelid 20. The tear-back portion 40 comprises a portion of thetop wall 24 and a portion of the mountingportion 30 of thelid 20. Of thetop wall 24, the tear-back portion 40 may comprise a portion of a recessedportion 25 of thetop wall 24. The tear-back portion 40 includes a plurality of side edges 42 and 44. The tear-back portion 40 also extends from a lower edge of theside wall 28 through an arcuate section of the mountingportion 30 to a trough or hinge 48 formed in a medial portion of thelid 20. Thehinge 48 serves as a pivotal hinge axis for the tear-back portion 40 so that as the tear-back portion 40 is torn away from the remaining portion of thelid 20, the tear-back portion 40 will rotate away from the rim of thecontainer 10 while pivoting about thehinge 48. The tear-back portion 40 may comprise any art recognized shape. - As shown in FIGS. 1-5, a
flange 50 may extend from the lower edge of theskirt 28 away from thecontainer 10 on the tear-back portion 40 of thelid 20 to providing a gripping surface for a consumer to grasp and pull in order to tear open the tear-back portion 40. In order to facilitate tearing, a pair of cuts ornotches 31 may be formed in theskirt 28 on either side of theflange 50 to provide a starting point for tearing open the tear-back portion 40. In another embodiment, a pair of score lines (not shown) may be formed in theskirt 28 on either side of theflange 50 to provide a starting point for tearing open the tear-back portion 40. - As well known in the art, each
side edge side edge corrugations 54. Thecorrugations 54 may be formed in thetop wall 24 spaced from one or both sides of a raised protrusion 60 (discussed below). While four corrugations are shown in each plurality ofcorrugations 54 in these FIGS., one of ordinary skill in the art should appreciate that the number of corrugations may comprise any number of corrugations. Thecorrugations 54 may be provided to direct the tearing of the tear-back portion 40 in a predetermined manner and prevent accidental and random tear directions. As the tear-back portion 40 is torn open, portions of the side edges 42, 44 are formed within thecorrugations 54, often just within thecorrugations 54 relative to the juncture of thecorrugations 54 and the smooth material area between thecorrugations 54 and the raisedprotrusion 60. In one embodiment, thecorrugations 54 are tilted toward each other so that the side edges 42, 44 of the tear-back portion 40 converge inwardly when formed. - As shown in FIGS. 1, 3, and7-9, after the tear-
back portion 40 has been opened relative to thecontainer 10, thelid 20 includes structure to enable the tear-back portion 40 to be locked or latched in an open position. Thelid 20 includes a raisedprotrusion 60 extending from atop surface 41 of the tear-back portion 40. Thelid 20 also includes arecess 70 positioned radially inward from the tear-back portion 40. The raisedprotrusion 60 is shaped such that when the tear-back portion 40 of thelid 20 is opened and pivoted about thehinge 48, the raisedprotrusion 60 is received within therecess 70 to retain the tear-back portion 40 in the open position. - More particularly, as shown most clearly in FIGS. 7-9, the tear-
back portion 40 may be latched in the open position by inserting the raisedprotrusion 60 into therecess 70 so that first latchingmembers 62, 64 (see FIG. 8) formed in opposite side walls of the raisedprotrusion 60 engage withsecond latching members 72, 74 (see FIG. 7) formed in opposing side walls of therecess 70. In use, as shown in FIG. 9, thelid 20 is somewhat flexible so that, when the raisedprotrusion 60 is inserted into therecess 70, the latchingmembers members back portion 40 is then latched in the open position because each first latchingmember second latching members back portion 40, one exerts an upward force on the tear-back portion 40 (for example, by pulling upward on the flange 50) to enable the latchingmembers members - In one embodiment, referring to FIGS. 8 and 9, a
flexural region 61 is formed in an upper portion of the raisedprotrusion 60. As used herein, the term “flexural region” comprises a region of the upper portion of the raisedprotrusion 60 that has flexibility to allow the raisedprotrusion 60 to flex at its upper portion when pressure is applied to the raisedprotrusion 60. Theflexural region 61 may be formed of any art recognized shape or structure that is capable of providing flexibility to the upper portion of the raisedprotrusion 60. For example, theflexural region 61 may be provided by an indentation in the upper portion of the raisedprotrusion 60 or a protrusion from the upper portion of the raisedprotrusion 60. Theflexural region 61 may comprise an indentation having, for example, a notch shape, a V-shape, or a U-shape. As shown in FIG. 8, theflexural region 61 is provided by anindentation 66 having a notch or V-shape. - More particularly, the
flexural region 61 allows the raisedprotrusion 60 to flex, thereby allowing the latchingmembers members back portion 40 in the open position. Also, after the tear-back portion 40 is latched, theflexural region 61 provides resistance so that the latchingmembers members back portion 40, theflexural region 61 also allows the raisedprotrusion 60 and, in particular, its upper portion, to return substantially to its original configuration. - As shown in FIGS. 1-3, a
second recess 80 is also formed in thelid 20 radially inward from therecess 70. Thesecond recess 80 is formed for receiving the mountingportion 30 of thelid 20 when the tear-back portion 40 is retained in its open position. - Referring to FIGS. 1-3 and10, in one embodiment, the
lid 20 includes at least onedrain groove 82 or a pair ofdrain grooves 82. Thetop wall 24 of thelid 20 may include an indented rim or plug 32 (see also FIGS. 4 and 6). Theindented rim 32 is positioned radially inward from the mountingportion 30. Theindented rim 32 may be formed around a portion of the circumference of thelid 20. Theindented rim 32 serves as a primary seal to engage the inside surface ofcontainer 10 and is capable of collecting liquid to avoid spillage thereof. Eachdrain groove 82 may be provided so that any liquid that collects in theindented rim 32 may drain through theopening 34 formed in thelid 20 into thecontainer 10. Thedrain groove 82 may comprise any structure or shape that is capable of allowing liquid to drain from theindented rim 32 back through theopening 34 into thecontainer 10. - As shown in FIGS. 1-3 and10, at least one
drain groove 82 connects with one or more corrugations of at least one plurality ofcorrugations 54 to drain liquid from theindented rim 32 through theopening 34 into thecontainer 10. In one embodiment having a pair ofdrain grooves 82, eachdrain groove 82 connects with one or more corrugations of each plurality ofcorrugations 54. Afirst end 84 of eachdrain groove 82 connects with theindented rim 32, while asecond end 86 of eachdrain groove 82 connects with at least onecorrugation 58 of each plurality ofcorrugations 54. In use, liquid may drain from theindented rim 32 through eachdrain groove 82 through its at least onecorrugation 58 through theopening 34 formed in thelid 20 into thecontainer 10. - In use, after a beverage is poured into the
beverage container 10, thelid 20 is snapped into place onto thecontainer 10 to releasably, sealably engage thecontainer 10 and thelid 20 by engaging the mountingportion 30 with the rim of thecontainer 10. To drink from thecontainer 10, the user grasps theflange 50 and then pulls to tear the lid material to form the tear-back portion 40. The side edges 42, 44 of the tear-back portion 40 are then formed through each pair ofcorrugations 54. The tear-back portion 40 is torn until thehinge 48 is reached. The tear-back portion 40 then pivots about thehinge 48. - The tear-
back portion 40 is pivoted so that itstop surface 41 is folded over the top surface of thetop wall 24 of thelid 20. The raisedprotrusion 60 of the tear-back portion 40 is then inserted into therecess 70 for latching engagement of the tear-back portion 40 in the open position. In particular, the tear-back portion 40 is latched in the open position by first latchingmembers protrusion 60 being first pushed past and then engagingsecond latching members recess 70. As shown, first latchingmember 62 is pushed past and then engages second latchingmember 74, while first latchingmember 64 is pushed past and then engages second latchingmember 72. Once the tear-back portion 40 is opened and, preferably when latched in the open position, the user drinks the beverage from thecontainer 10 through theopening 34 formed in thelid 20. - In one embodiment, the
lid 20 includes a straw slot opening (not shown) that functions as a means for facilitating the insertion of a drinking straw (not shown) into thecontainer 10 for withdrawing liquid by suction. - At places where a user would buy a beverage in a cup, such as fast food establishments, gas stations, or convenience stores, the cups and lids may be stacked with a lid on each cup (“cup-on-lid stacking”), or by stacking a plurality of cups together and also stacking a plurality of lids together (“lid-on-lid stacking”).
- Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the following claims.
