DETAILED DESCRIPTION

(16) Referring now to the drawings, where like numerals identify like elements, there is shown in FIG. 1 a package which is generally referred to by the numeral 10. In FIG. 1, the package 10 is comprised of a container or base 12 and a lid or cap 14. The lid 14 is shown positioned on and fixed to an upper portion of the base 12. In FIG. 2, the lid 14 is exploded away from the base 12, exposing retaining structures 16 on the upper or top end 18 of the base 12. A rim 20 on the lid 14 is contoured to fit onto and mater with the tope end 18 of the base 12. In FIG. 3, the lid 14 is inverted, exposing a portion volume 22 defined within the interior of the lid 14. Lid engagement structures 24 are formed within the interior of the lid 14, adjacent to the rim 20. Arrows 26 are shown in FIG. 3 representing an opening or release force that is applied to a pair of activation buttons 28 on opposite sides of top end 18 of the base 12. The release operation is described in further detail below. The interior of the base 12 forms a retaining volume 30 for storage of a consumable product or goods (not shown). Access to the retaining volume 30 is provided through an opening defined in the top end 18 of the base 12. The access opening is surrounded by a base rim 32.

(17) In FIG. 4, the package 10 is shown in an exploded condition, with both the base 12 and lid 14 supported in a generally illustrated cup holder 34. The holder 34 of the type generally shown is typically provided at various positions within automobiles, on furniture, or as part of other devices and is generally use for supporting a drink cup and other objects. A typical cup holder has an internal diameter of about 2.5 inches to 3 inches. Various spring loaded structures (not shown) may be provided to resiliently secure a cup or other object and to deter release of the cup, etc based on movement, vibration or the like. In FIG. 4, it is shown that the preferred outside dimensions of the base 12 and the lid 14 are set to be snuggly received within the cub holder 34. The base 12 is separated from the lid 14, with the portion volume 22 of the lid 12 exposed to receive contents from the retaining volume 30 of the base 14. The contents in the lid 12 may be accessed by the user, such as a driver, passenger or the like (not show).

(18) In FIGS. 5 and 6, the package 10 is shown in side elevation. In FIG. 5, one activation button 28 is visible, with a second similarly formed button provided on the opposite side of the container base 12. In FIG. 6, the package 10 is rotated 90 degrees about a central vertical axis from the view in FIG. 5 and two buttons 28 are shown in profile on opposite sides of the base 12. In both figures, the lid 14 is retained on the top end of the base 12. In FIG. 7, the lid 14 is released from the top end 18 of the base 12, exposing the contours of the rim 20 of the lid 12. A shoulder or lip 36 is provided in the sidewall of the base 12. The shoulder 36 is formed to receive the rim 20 of the lid 12 to create a smooth or integrated outside surface for the package 10, when assembled (such as that shown in FIGS. 5 and 6).

(19) In FIGS. 8-11, the assembled package 10 is shown in cross section with various features of the engagement structures 16 illustrated. As shown in FIG. 7, for example, there are two retainer grooves 38 positioned on opposite sides of the activation button 28. In FIG. 3, for example, the inside surface of the sidewall 40 of the lid 14 includes a retainer bar 24 extending between the cutouts or contour slots 42 on the rim 20 that receive the buttons 28 on the base 12. The engagement structures 16 are detailed in FIG. 9 and include the retainer bars 24 on the lid 12 and the receiving grooves 38 on the top end 18 of the base 12. The grooves 38 receive a portion of the bar 24 and form a friction fit for retaining the lid 14 on the top end 18 of the base 12. The rim 20 of the lid 14 is preferably secured against the shoulder 36 within the sidewall of the base 12. The top end 18 of the base 12 extends upwardly from the shoulder 36. There is an overlap created of the sidewall 40 of the lid 14 and the top end 18 of the container 12. This overlap by the extension of the top end 18 of the base 12 serves to maximize the retaining volume 30. The height of the sidewall 40 of the lid 14 serves to fix the lid volume 22 and set the maximum serving portion for product or goods.

(20) In FIG. 10, the container rim 32 is shown spaced from the top wall 42 of the lid 14. This spacing is optional. An engagement of the rim 32 with the lid top wall 42 may assist in sealing the interior volume 30 of the base 12. A stabilizing ridge 44 is shown in the corner of the sidewall 40 and top wall 42 of the lid 14. This ridge 44 is positioned adjacent the rim 32. A sealing engagement by the rim 32 with the ridge 44 may also be formed. Alternatively or in addition to the engagement between the rim 32 and the lid 14, a membrane (not shown) may be releaseably fixed to the base rim 32 for sealing the contents of the base container 12. The membrane is typically removed by the user during initial opening of the package 10, with the lid 14 preferably forming a freshness seal after the opening. An outer wrapper (not shown) may also be provided for sealing the package. For example, a shrink wrap label may surround the package, securing the base and lid and providing decorative graphics. Further, an extended ledge or shelf (not shown) may be provided on the rim 32 of the container 12 for supporting or suspending a dip cup or the like. The dip cup preferably holds a complimentary sauce for application to the contents of the container base during consumption.

(21) The retaining grooves 38 are shown to be discontinuous around the perimeter of the top end 18 of the base 12. The grooves 38 are tapered away from the position of the buttons 28. The tapering of the grooves 38 assists in release of the lid 14 from the base 12. In FIGS. 12-14, there is shown the engagement of the retainer bar 24 on the lid 14, outside the channel formed by the retainer grooves 38. In FIG. 12, the buttons 28 are shown in cross section with the retainer grooves 38 positioned adjacent the buttons 28. The contours of the rim 20 of the lid 14 define a pair of slots 46 that surround the buttons 28 upon assembly. The opposite side retainer bars 24 discontinue in the area of the contour slots 46. A space 48 is provided between the receiving grooves 38 on the top end 18 of the base 14. This space 48 is formed without grooves or engagement ridges. As shown in more detail in FIG. 14, the retainer bar 24 contacts the wall of the top end 18 of the base 12 in the space 48 between the grooves 38. In addition, the thickness of the relatively central portion 24a of the retainer bar 24 is preferably less than the thickness of the bar portions received within the grooves 38. A comparison of FIGS. 9 and 14 further identifies this dimensional difference and the corresponding engagement between the lid 14 and the top end 18 of the base 12.

(22) The engagement structures 16 on the top end 18 of the container base 12 provide means for engagement of the retainer bars 24 on the lid 14 to fix the lid 14 to the top end 18 of the base 14 and to form the assembled package 10. The retainer bar 24 engages within the grooves 38 in a friction fit. The central portion 24a of the retainer bar further engages the sidewall of the top end 18 of the base 14.

(23) The retained lid 14 is released from the base 12 by application of the release force 26 (see arrows in FIG. 3). The release force 26 causes a flexing and deformation of the sidewall of the base 12, reducing the lateral dimension at the buttons 28 and increasing the lateral dimension at the location of the space 48, between the grooves 38. The increase in dimension causes the retainer bar 24 to move out of the grooves 38, preferably with a release pop being created.

(24) Based on the contemplated dimensions and materials of the package 10, a typical user will be able to squeeze the base 12 with one hand, applying the release force 26 at the buttons 28. The release of the lid 14 will move into the user's hand, providing easy removal and then inversion of the lid 14. The contours 46 on the rim 20 of the lid 14 may assist in gripping the released lid. Once inverted, the portion control volume 22 of the interior of the lid 14 is accessible. A portion of the retained contents within the interior volume 30 of the base 12 may then be easily poured into the volume 22 of the lid 14.

(25) Replacement of the lid 14 onto the top end 18 of the base 12 is easily accomplished by a downward force 50 (FIG. 12) on the top wall 42 of the lid 14, causing the engagement structures 16 to interact. The contour slots 46 provide for proper alignment of the lid 14 with the base 12. The slots 46 preferably surround and mate with the projecting buttons 28 on the top end 18 of the base 12.

(26) As a non-limiting example, the base 12 of the package 10 may be dimensioned to retain a overall volume 30 of goods of about eight (8) ounces, with the lid volume 22 formed to receive about two (2) ounces. Hence, the package 10 retains about four (4) individual servings. The size of the lid 14 defines the serving portion and additional portions may be consumed only after pouring an additional amount into the portion volume 22 defined by the lid 14. The additional step of dispensing a new portion has been found to deter excess consumption.

(27) In the drawings and specification, there has been set forth a number of embodiments of the invention and, although specific terms are employed, these terms are used in a generic and descriptive sense only and not for purposes of limitation. The scope of the invention is set forth in the following claims.
