DETAILED DESCRIPTION

(18) Referring to FIGS. 1A-5 there is shown a first embodiment of a sealing cover in accordance with an aspect of the invention, generally indicated at 10. As best seen in FIG. 1B, sealing cover 10 may comprise a base 28 and a lid 32 that are engaged with each other via a flexible hinge or bridge 24. Bridge 24 may be integrally formed with base 28 and lid 32 or may be a separate component that is heat welded or otherwise connected to base 28 and to lid 32.

(19) Base 28 may be configured to be engaged with an upper rim of a beverage container 12 (FIG. 2A). Lid 32 may be movable about bridge 24 and relative to base 28 between an open position (FIG. 2A) and a closed position (FIG. 2B). When lid 32 is in the open position the contents of beverage container 12 may be accessed. When lid 32 is in the closed position, the contents of beverage container 12 may not be accessed. Sealing cover 10 will be described in greater detail below.

(20) It should be noted that when cover 10 is in the closed position, lid 32 is located vertically above and aligned with base 28. The bridge 24 that extends between lid 32 and base 28 may be folded back upon itself as shown in FIG. 3A. When lid 32 is moved to the open position, i.e., out of vertical alignment with base 28, bridge 24 unfolds to the position shown in FIG. 1B.

(21) It will be understood that instead of a flexible or living hinge, bridge 24 may be replaced with any other type of hinge or connecting mechanism to secure lid 32 and base 28 together and prevent them from becoming detached from each other.

(22) Sealing cover 10 may be fabricated from one or more plastic materials that are appropriate and approved for use in the food industry for coming into direct contact with solid or liquid foods and beverages. Suitable plastic materials for sealing cover 10 may include but not be limited to polypropylene, polyethylene, or polycarbonate.

(23) Base 28 may comprise a wall shaped and sized to be complementary to the beverage container 12 with which sealing cover 10 is to be engaged. Since beverage container 12 is illustrated as being generally circular in shape when viewed from a top end (i.e., the end that includes the opening through which the contents of container 12 are accessed), the wall of base 28 may be generally circular in shape when viewed from above. This can be seen in FIG. 1B. If beverage container 12 is differently shaped, when viewed from a top end, such as being square, rectangular, oval, triangular, or any other unique shape or configuration; the wall of base 28 will be fabricated to be complementary in shape to that top end of the container 12.

(24) An inner surface of the wall of base 28 bounds and defines an opening 28a through which the aperture defined in a top end of container 12 may be accessed. Opening 28a may extend from proximate an upper end of the wall to proximate a lower end of the wall. A first sealing member may be provided on base 28. As shown in FIG. 1B, the first sealing member may comprise a protrusion 22 provided on base 28. Protrusion 22 may be provided on an upper end of base 28 and may be shaped as a generally circular projection (FIG. 1A) that extends upwardly and outwardly from the upper end of the wall. Protrusion 22 may be an annular protrusion that is provided along substantially the entire circumference of the wall of base 28. It will be understood that protrusion 22 may be provided anywhere else on the wall of base 28 that will allow base 28 to be latched and ultimately sealed to lid 32.

(25) A lower end of the wall of base 28 defines a first channel 34 that may extend along substantially the entire circumference of the wall. First channel 34 may be configured to be complementary to a rim 12a (FIG. 4A) provided on container 12. FIG. 3A shows that first channel 34 may be defined by a generally U-shaped region of the lower end of the wall of base 28. When sealing cover 10 is engaged with container 12, rim 12a is snugly received within first channel 34 of base 28 and base 28 is retained on rim 12a by friction. Base 28 of cover 10 may be snap-fitted onto the rim 12a of container 12 after a consumer has purchased the container 12 and the cover 10.

(26) The inner surface of the wall of base 28 may also define an annular first groove 28b (FIG. 3A) that may extend around substantially the entire circumference of the wall. The outer surface of the wall of base 28 may also define an annular second groove 28c that may extend around substantially the entire circumference of the wall. Annular first and second grooves 28b, 28c may be provided proximate a lowermost region of protrusion 22. Grooves 28b, 28c ensure that protrusion 22 is able to flex from side-to-side during engagement of lid 32 with base 28 and during the progressive sealing of cover 10.

(27) One or more first flanges 36 (FIG. 1B) may extend radially outwardly from the outer surface of the wall of base 28. FIG. 1B shows two first flanges 36 that are laterally spaced a distance apart from each other and define a recessed region 37 between them.

(28) Lid 32 or at least a portion of lid 32 may be configured to be complementary in shape and size to base 28. So, as is illustrated in FIG. 1B, if base 28 is configured to be substantially circular in shape when viewed from above, then lid 32 or at least a portion of lid 32 may be substantially circular in shape. Obviously, if base 28 is differently configured, such as being square, rectangular, oval, elliptical, triangular or any other shape when viewed from above, then lid 32 or at least a portion of lid 32 may be substantially similarly configured.

(29) Lid 32 comprises a top wall 26 and an annular wall 27 that circumscribes top wall 26. Annular wall 27 defines a second channel 30 in a location that is complementary to the location of protrusion 22 on base 28. As illustrated, second channel 30 may be provided on a lowermost surface of annular wall 27. In accordance with an aspect of the invention, second channel 30 may be defined to be complementary in shape, size and location to protrusion 22 provided on base 28. When lid 32 is positioned vertically above and aligned with base 28 by moving lid 32 to the closed position (FIG. 3A), protrusion 22 may be snugly received in second channel 30 of lid 32 and be retained therein by friction. Lid 32 and base 28 may initially be latched together by protrusion 22 entering channel 30. However, lid 32 and base may subsequently be progressively sealed and thereby locked together in such a manner that even liquid may tend not to flow out of the sealed container 12. This will be described later herein.

(30) FIG. 3A shows that annular wall 27 (or top wall) of lid 32 defines a first annular shoulder 27a that is complementary shaped and sized to be received in first groove 28b of base 28; and defines a second annular shoulder 27b that is complementary shaped and sized to be received in second groove 28c of base 28.

(31) A second flange 38 may extend radially outwardly from an exterior surface of annular wall 27. Second flange 38 may be located in such a way on annular wall 27 that when lid 32 is moved to a closed position, second flange 38 is located laterally adjacent at least one of the first flanges 36. Preferably, second flange 38 may be seated in the recessed region 37 defined between the two first flanges 36.

(32) A first end of flexible bridge 24 may integrally formed with an exterior surface of base 28 and a second end of flexible bridge 24 may be integrally formed with an exterior surface of lid 32. As shown in FIG. 1B, a middle region of flexible bridge 24 may be narrower in width than either of the first end or second end thereof. Additionally, flexible bridge 24 is relatively thin and is therefore more readily able to flex and bend or fold over on itself.

(33) Sealing cover 10 may be formed as an individual component (FIG. 1B) that may be snap fitted onto beverage container 12 or any other type of can after the production of container and the purchase thereof by a consumer. So, a user may purchase sealing cover 10 and beverage container 12 separately, and engage sealing cover 10 on the rim 12a of container 12 either before container 12 is opened or after container 12 is opened.

(34) FIG. 2A shows a pull tab 16 on a top wall 14 of container 12 has been moved to an open position to provide access to an aperture 18 into the interior of container 12. A person may drink from container 12 or pour some of the contents thereof out through aperture 18 and then move sealing cover from the open position shown in FIG. 2A to the closed position shown in FIG. 2B. This is accomplished by rotating lid 32 in the direction of arrow B (FIG. 2A) to bring second channel 30 on lid 32 into alignment with protrusion 22 on base 28.

(35) Once lid 32 is moved to the closed position, a user may initially align first second channel 30 with protrusion 22 and press downwardly in the direction of arrow A (FIG. 3). This will cause protrusion 22 to at least partially enter into first second channel 30 thereby latching lid 32 to base 28. In order to ensure a close sealing engagement between lid 32 and base 28, the user may then progressively run his or her finger along the perimeter of the upper edge 27c of annular wall 27, and around the circumference thereof, applying a gentle downward pressure in the direction of arrow A. This motion will cause lid 32 to be progressively sealingly engaged with base 28 in a zipper type closure where protrusion 22 more or less fully enters into the complementary channel 30. This progressively application of pressure may ensure a tight seal between lid 32 and base 28. Because of the flexibility of the material used to fabricate sealing cover 10 and because of the side-to-side flexibility of protrusion 22 created by grooves 28b, 28c; lid 32 and base 28 are sealingly engaged with each other.

(36) During the sealing engagement of lid 32 and base 28, annular shoulder 27a on lid 32 enters into annular first groove 28b on base 28, thereby ensuring a close seal between lid 32 and base 28. This is shown in FIG. 4B where it can be seen that sealing cover 10 closes off access to the interior chamber 12b and thereby to the contents 13 retained therein. (The interior chamber 12b of container 12 is bounded and defined by the bottom wall and side wall of the container 12. An opening to the interior chamber 12b is provided at an end of the container opposite bottom wall. The opening may comprise a small region of a top wall of the container or the entire top wall may be omitted in which case the opening is bounded by an upper rim of the side wall of the container.)

(37) If a user later decides he or he wishes to gain access to the contents 13 in the interior chamber 12b (FIG. 4A) of container 12, he or she will engage first flange 36 with their finger and will push upwardly thereon in the direction of arrow C (FIG. 3B). This motion will move sealing cover 10 back into the open position shown in FIG. 4A.

(38) A method of resealing a container 12 in accordance with an aspect of the present invention, where the container 12 contains a substance, such as a beverage, food or another material in the interior chamber 12b thereof, and wherein the container has a side wall with an upper rim 12a, may comprise steps of engaging a base 28 of a cover 10 on the upper rim 12a of the side wall of the container 12; moving a lid 32 engaged with base 28 into a position vertically above base 28 (such as is shown in FIG. 4B); aligning a channel 30 (FIG. 1A), (or 52 (FIG. 6B) or 120 (FIG. 9)) defined in one of lid 32 and base 28 with a protrusion 22 (FIG. 1A) (or 50 (FIG. 6B or 122 (FIG. 9)) provided on the other of the lid and the base; pushing the lid 32 downwardly in the direction of arrow A (FIG. 3A) toward the base to engage the protrusion in the channel; progressively applying pressure (by way of a fingertip) to a perimeter of an outer surface of the lid; and sealing lid 32 and base 28 together.

(39) FIGS. 6A to 6C show a second embodiment of a sealing cover in accordance with an aspect of the present invention, generally indicated at 54. Cover 54 is illustrated as being engaged with a can 40 such as a can of pet food. Can 40 includes a side wall that has a rim at an upper end thereof. Sealing cover 54 comprises a base 48 and a lid 46 that may be fabricated as separate components. After fabrication of can 40, a small and inexpensive addition is made to can 40 in the form of overmolding the rim of side wall 41 with base 48. Base 48 and lid 46 are assembled with lid 46 positioned on top of base 48 and the two components are heat-sealed together, such as at molded tabs 56 and 58 (FIG. 6C). (t will be understood that any other suitable method of securing or welding the plastic base 48 and lid 46 may be utilized instead of heat-sealing.)

(40) FIG. 6A shows lid 46 rotated into an open position and the can's lid 42 in an open position. The can's lid 42 is moved to the open position by pulling on the pull tab 44. FIG. 6B shows the can 40 with the can's lid 42 completely disengaged from the can and the sealing cover 54 in the open position. It should be noted that after sealing cover 54 is moved to the open position, the can 40 may be opened and the can's lid 42 completely detached from the can without removing sealing cover 54 from its engagement with can 40. FIG. 6C shows lid 46 of sealing cover 54 moved to a closed and sealed position. Lid 46 is rotated into the closed position such that the protrusion 50 on base 48 is received in the channel 52 on lid 46. Lid 46 is initially latched by pushing downwardly thereon and then the user will run their finger around the perimeter of lid 46 progressively pushing downwardly to zipper lock lid 46 to base 48 in the same manner as lid 32 is locked to base 28. Cover 54 may easily be opened by engaging tab 56 and pushing upwardly thereon.

(41) If the user does not wish to reseal can, lid 46 may be disengaged from base 48 by applying a pulling force thereto to break the seal at tab 58.

(42) The can 40 will be purchased by the consumer looking the same way as is illustrated in FIG. 6C, i.e., in a closed position. Cover 54 keeps the can's lid 42 in a sanitary condition by preventing dust, dirt, debris etc. from accumulating on lid 42. Allowing dust, dirt, debris, etc. to accumulate on a can lid may present a health and safety hazard for consumers. Cans stored in warehouses, factories and shops may be exposed to mice and other rodents and there have been documented cases of E. coli contamination from consumers drinking directly from soda cans. Sealing cover 54 provides an inexpensive option to aid in preventing the can's lid 40 from being contaminated. Additionally, if the can 40 is a soda can, it is easy for the consumer to prevent bees and other insects from entering into can 40 when the consumer is not actively drinking therefrom by simply pushing lid 46 into the closed position. If the consumer desires to access the contents at a later time, the lid 46 may then be moved to the sealed and position by running their finger around the perimeter of lid 46 and gently applying pressure thereto.

(43) FIG. 7 illustrates a sealing cover 80 in accordance with an aspect of the present invention being used on a paint can 82. Cover 80 includes base 84 and lid 86 that are engaged with each other via a flexible bridge 88. Cover 80 may be substantially identical to cover 10 and therefore will not be described in any more detail herein. Base 84 may be engaged on a rim at an upper edge of the side wall of paint can 82 and lid 86 may selectively be moved between the open and closed positions in a similar manner as with the first and second embodiments described herein. Cover 80 may be provided as an aftermarket product that is purchased separately and then engaged by the consumer on paint can 82 in a similar manner to cover 10. Alternatively, cover 80 may be applied in the factory after fabrication of the paint can 82 by overmolding base 84 and then heat-sealing lid 86 thereto in a similar manner to cover 54.

(44) In use, lid 86 will be moved to the open position in order to gain access to the paint within paint can 82. When the consumer wishes to close and seal paint can 82 to prevent the paint from drying out or from becoming contaminated, lid 86 is moved to the closed position by pushing downwardly thereon until a protrusion on the base 84 is received in a channel on the lid 86. This latches lid 86 to base 84. The consumer will then push downwardly and move their finger along the top surface of the lid 86 and around the perimeter thereof to progressively zipper lid 86 closed to base 84. A flange 89 on lid 86 may be engaged and pushed upwardly to reopen lid 86 at a later time.

(45) It will be understood that the sealing cover disclosed herein is contemplated to be fabricated in any size or shape and to be used on cans or containers that contain any type of product, but particularly food and beverages.

(46) FIG. 8 shows a blister pack 90 that includes a sheet of material into which a plurality of sealing covers 92 are molded or stamped therein. Each sealing cover 92 comprises a base 94, a lid 96 and a flexible bridge 98 extending therebetween. The consumer may purchase blister pack 90 and selectively remove the sealing cover 92 therefrom for use. The single sealing cover 92 is removed from the rest of blister pack 90 by pushing on the lines of weakness 100 that circumscribe that particular sealing cover 92. The detached sealing cover 92 may then be used in a similar manner to sealing cover 10. Blister pack 90 may contain one or more sealing covers 92 thereon that may be individually detached from blister pack 90.

(47) FIGS. 1-6C show that the protrusion 22 or 50 may be provided on base 28 or 48, respectively; and that second channel 30 or 52 may be provided on lid 32 or 54, respectively. FIG. 9 shows a third embodiment of the sealing cover, generally indicated at 110. Sealing cover 110 may comprises a base 112 and a lid 114 that are connected together by a flexible bridge or living hinge 116. Cover 110 may be substantially identical to cover 10 with the exception that a protrusion 118 is provided on an underside of lid 114 and a second channel 120 is defined in the upper side of base 112. The cover 110 is engaged with a can or container by a rim on an upper end of the can or container being received in a complementary first channel 122 provided on a lower end of base 112. Base 112 and lid 114 of cover 110 may be latched and subsequently progressively sealed together in substantially an identical manner to the base and lid of cover 10.

(48) It will be understood that while this invention has been described mainly for use in conjunction with a metal can or container, the sealing covers disclosed herein may be engaged with the rims of glass or plastic jars or bottles or any other types of containers no matter the type of material from which those containers are fabricated.
