DETAILED DESCRIPTION

[0021] It is to be understood that the inventions are not limited to the details of construction in the arrangement of the components set forth in the following description or illustrated in the drawings. The inventions are capable of other embodiments or of being practiced or carried out in various ways. It is also to be understood that the terminology employed in this application is for the purpose of description and should not be regarded as limiting.

[0022] FIG. 1 illustrates a container 10 having a receptacle 12 and a cap or cover 14. As shown, cover 14 includes a shaker flap 16 that covers (when closed) shaker openings 18 disposed in planar top portion (or end) 20 of the cover. Cover 14 also includes a spooning flap 22 that similarly covers a larger spooning opening 24 also disposed in top portion 20.

[0023] The cover (as shown in FIG. 2) is in the form of a substantially cylindrical portion 26, and top portion 20 which is coupled to an upper end of cylindrical portion 26 to cover cylindrical portion 26. As shown in FIG. 1, threads 28 are provided on the inner surface of cylindrical portion 26 for coupling cover 14 to the outside of the top of a receptacle 12. As shown in FIG. 1, mating threads are disposed on an outer indented top portion of receptacle 12 to engage threads 28. Alternatively, cylindrical portion 26 may be equipped with an inner detent or a raised ring to allow it to be snap connected to the top portion of receptacle 12. According to an exemplary embodiment as shown in FIG. 2, an elongate recess 19 is provided in which shaker flap 16 will fit when flap 16 is in a closed position, to provide a substantially flat upper surface of top portion 20 on which a similar container can be stacked.

[0024] As shown in FIG. 1, receptacle 12 includes a substantially planar bottom portion 30 that is adapted to engage a lip 32 of cover 14. The bottom portion 30 is adapted to engage lip 32; a plurality of containers (see FIGS. 1 and 13) can be stacked one atop the other, lip 32 serving to orient the bottom of the next higher container and intended to keep the containers in proper alignment when stacked. In FIG. 1, two containers are shown (partially) in this stacked arrangement, the bottom of the upper container being shown as dashed line 34 engaging rim 32 when the flaps of the lower container are in a closed position (shown in FIG. 1 as dashed lines when in their closed positions). Bottom portion 30 of receptacle 12 (and hence bottom portion of container 34) and top portion 20 of cover 14 with lip 32 are adapted to engage one another. As shown in FIGS. 1, 3, and 13, lip 32 is disposed at an outer edge of cover 14 to engage a recess 36 at the junction of bottom 30 and wall 38 of receptacle 12. By disposing both lip 32 and recess 36 to engage each other near the outer periphery of the container, containers are more easily stacked (and when stacked tend to self-center). A portion of lip 32 is preferably disposed on shaker flap 16, spooning flap 22 and on the non-hinged sides of top portion 20 as shown in FIG. 4. Each of these portions is preferably disposed at an outer edge of cover 14 (and have substantially the same diameter).

[0025] Referring to FIGS. 1 and 2, a plurality of shaker openings 18 (preferably substantially circular as shown) are provided to allow foodstuffs within the container to be shaken out when shaker flap 16 is opened. Openings 18 are (preferably) shown arranged along an arc (as shown in FIG. 2). On the underside of shaker flap 16 is an arcuate flange 40 adapted to engage and seal central shaker opening 18 which extends for about 30 degrees around the periphery of its mating opening 18 when in a closed position (as shown in FIG. 5). Flange 40 engages the inner surface of opening 18 and holds the shaker flap closed.

[0026] FIG. 3 shows cover 14 in cross-section along a diametral line of the cover. The cross section is shown perpendicular to both the shaker flap hinge 50 and the spooning flap hinge 58. Flange 40 extends, downward from the underside of shaker flap 16 (and outward) at an angle of between 9 and 25 degrees (preferably of between 5 and 20 degrees) with respect to the longitudinal axis of container 10. This angular relationship allows the cover, including the flaps, to be readily and integrally molded as a single monolithic piece (in the orientation shown generally in FIGS. 1 and 13, e.g. with flaps as depicted at approximately 15 to 20 degrees from vertical). In addition, this angle allows flange 40 to releasably lock into central opening 18 when shaker flap 16 is closed.

[0027] Shaker flap 16 also includes a skirt 46 that extends downwardly from shaker flap 16. Skirt 46 is disposed at an outer edge of shaker flap 16. Skirt 46 is shown as indented into the cap to provide (together with the outer surface of cylindrical portion 26), a substantially right circular cylindrical wall.

[0028] Skirt 46 has an indentation 48 shown as disposed at a central outer portion of skirt 46 and is configured to receive a finger or finger nail of the user to allow the user to grasp shaker flap 16 at the indentation and readily open container 10 by lifting upward.

[0029] Skirt 46 preferably extends around cover 14 for an arcuate length of between 60 and 120 degrees (see FIG. 4). According to an exemplary embodiment shown in FIG. 4, skirt 46 forms between 60 and 120 degrees of the circumference of the upper part of cover 14. Skirt 46 is arcuate (rather than straight) to distribute the grasping load more evenly around the outer edge of shaker flap 16 and is less likely to be bent when the cover is grasped and opened. The arcuate configuration of skirt 46 allows shaker flap 16 to be made thinner and therefore to require less plastic when manufactured.

[0030] Referring to FIG. 3, when the shaker flap 16 is closed, flange 40 engages an outer portion of shaker opening 18 to releasably lock shaker flap 16 to top portion 20 in a closed position. While only a single flange 40 is shown in cross section in FIG. 3, each of the other openings 18 may also have a flange (not shown) to provide additional engagement surfaces for holding the shaker flap closed.

[0031] As shown schematically in FIG. 4, shaker flap 16 is coupled to top portion 20 by a flexible and integrally formed hinge 50 preferably extending the entire length of shaker flap 16.

[0032] As shown schematically in FIG. 4, spooning flap 22 is coupled to top portion 20 by a flexible and integrally formed hinge 58 preferably extending the entire length of spooning flap 22. Hinges 50 and 58 are disposed adjacent to a diametral line of cover 14 to allow the flaps to hinge upward and toward the middle of cover 14.

[0033] According to an exemplary embodiment shown in FIG. 3, spooning flap 22 covers spooning opening 24. Spooning flap 22 has a flange 52 depending from a lower surface of spooning flap 22 that engages and locks against the inside of opening 24. Flange 52 extends at an angle (preferably between 9 and 25 degrees) outward and downward from the underside of spooning flap 22.

[0034] As with flange 40 of the shaker flap, by disposing flange 52 at an angle, cover 14 can be manufactured in a single piece with spooning flap 22 formed integrally with cover 14. Flange 52 preferably has an arcuate length of between 20 and 180 degrees (shown as approximately 20 degrees). Over this length, flange 52 is intended to engage the inside edge of spooning opening 24 to releasably lock spooning flap 22 to top portion 20 when spooning flap 22 is in a closed position.

[0035] As shown schematically in FIGS. 1 and 3, spooning flap 22 includes a skirt 60 (like skirt 46 of shaker flap 16). Skirt 60 is shown extending downwardly from spooning flap 22 near an outer edge of spooning flap 22 and has an arcuate shape to define an outer substantially vertical surface of cover 14 when spooning flap 22 is in a closed position. Skirt 60 has an indentation 61 shown disposed at a central outer portion of skirt 60 and configured to receive a finger or fingernail of the user to allow the user to grasp spooning flap 22 at the indentation and readily open container 10. Skirt 60 preferably extends around the circumference of cover 14 when in the closed position for an angle pi of between 100 and 150 degrees (see FIG. 4). Skirt 60 is arcuate (rather than straight) to distribute the grasping load more evenly around the outer edge of spooning flap 22 and is less likely to be bent when the cover is grasped and opened. The arcuate configuration of skirt 60 allows spooning flap 22 to be made thinner and therefore to require less plastic when manufactured. According to an exemplary embodiment shown in FIG. 4, the arcuate length of skirt 60 is greater than the arcuate length of skirt 46 and therefore provides additional strength to spooning flap 22.

[0036] A recess 62 (shown in FIG. 2) is provided in the cylindrical portion of cover 14 to receive skirt 46 of shaker flap 16, so that skirt 46 can be set into an outer surface of cover 14 when shaker flap is closed, to reduce the risk that skirt 46 will be accidentally jostled and caught, shaker flap 16 opened and the contents of container 10 spilled; a recess 64 is provided on the opposite side of cover 14 from recess 62 to receive skirt 60 of spooning flap 22. Skirts 46 and 60 form a smooth and contiguous part of the outer surface of the cylindrical portion of cover 14.

[0037] As shown schematically in FIGS. 1 and 3, rim 70 of receptacle 12 has an upper sealing surface 72 that abuts a projection (shown as sealing ring 74) of the cover when the cover is screwed onto the receptacle. According to an exemplary embodiment shown in FIGS. 10 through 12, sealing ring 74 is spaced apart from cylindrical portion 26 of cover 14 to form a gap 77. According to an exemplary embodiment shown in FIGS. 13 and 15, a sealing projection 74a provides a sealing surface that extends from the underside of top portion 20 of cover 14 (within cylindrical portion 26 to provide a gap 77).

[0038] As shown in FIGS. 1, 3 and 5 through 12, sealing ring 74 has several separate and distinct sealing surfaces 76; surfaces 76 are flat and separated from adjacent sealing surfaces by cylindrical walls 79 (shown as circular and parallel to the longitudinal axis of the cap so that sealing surfaces 76 are arranged in a “stair step” fashion, see FIG. 7). Each sealing surface defines a plane that is substantially perpendicular to the longitudinal axis of the receptacle and cover. As shown schematically in FIGS. 6 and 7, a “warped” bottle with an oval rim 70 and sealing surface 72 may be screwed into cover 14.

[0039] FIGS. 10-12 show (schematically) a receptacle rim 70 as it approaches sealing surface 76 of cover 14 (as the cover and receptacle are rotated with respect to each other).

[0040] As shown in FIGS. 7 and 9, there are four sealing surfaces 76a and 76b and 76c and 76d on cover 14 (each having a slightly smaller diameter) so that cover 14 may be attached to receptacles with different rim diameters (e.g. receptacles with a smaller rim diameter will rest on sealing surfaces that also have smaller diameters and receptacles with a larger diameter will nest on sealing surfaces with larger diameters).

[0041] According to alternative embodiments, the arrangement of the cover is intended to accommodate a receptacle having variety of mouth sizes by providing several sealing surfaces against which the mouth of the receptacles can seal and/or to correct the shape of warped bottles (e.g., used with automatic capping machines).

[0042] The present inventions are intended to embrace all alternatives, modifications and variations that fall within the spirit and broad scope of the claims.
