DETAILED DESCRIPTION

Before turning to the figures, which illustrate the exemplary embodiments in detail, it should be understood that the present invention is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology is for the purpose of description only and should not be regarded as limiting.
Generally, various embodiments of a closure are provided. In specific embodiments, the closure is adapted for use with a container having a threaded, cylindrically shaped neck, such as the type often used for storing and dispensing foodstuffs, spices, seasonings, etc. commonly found in supermarkets and grocery stores. The closure includes a body and a fitment that is coupled to the body. As such, removal of the closure's body from the container, such as by unthreading the body from the neck of the container, correspondingly removes the fitment from the neck of the container, allowing ready access to the contents of the container with a kitchen tool, such as a measuring spoon, without the need to separately pry a tightly fitted fitment from the neck of the container itself. If the user desires to frequently use the container without a fitment, the user may remove the fitment from the body and then reapply the body to the container neck without a fitment. If the user desires to increase or decrease the rate at which the contents of the container are dispensed during a dispensing motion, such as by inverted shaking or sprinkling, the user may alternatively couple a different fitment with a different pattern of dispensing apertures to the body before reapplying the body to the container neck.
Referring to FIGS. 1 and 2 , various perspective views are shown of a closure 10. The closure 10 includes a fitment 20 coupled to a body 40. The body 40 includes a base 42 coupled to a cover 44 (e.g. a lid). In specific embodiments, cover 44 is coupled to base 42 by a hinge 45. In more specific embodiments, the hinge 45 is a butterfly hinge. The cover 44 is configured to transition from an open position, in which fitment 20 is at least partially uncovered by cover 44 to allow the dispensing of particulate matter through fitment 20, and a closed position, in which the fitment is covered by cover 44 to block the dispensing of particulate matter through fitment 20. In specific embodiments, a portion of cover 44, more specifically, a portion located opposite from hinge 45, is configured to snap fit to base 42 when the cover 44 is transitioned to a close position.
In specific embodiments, fitment 20 is snap-fit to base 42. As such, when the cover is in an open position and separated from the container neck, a user may apply downward pressure to the fitment 20 from above to release, or unsnap, fitment 20 from base 42. The user may likewise reapply the same fitment 20 or a different fitment by positioning the fitment within base 42 and applying an upward pressure from within base 42 to the fitment to secure, or snap, the fitment into base 42. As used here, directional terms, such as “upper,” “lower,” and “above,” are used with reference to the orientation of closure 10 shown and described in FIGS. 1-2 .
Referring to FIGS. 3-6 , various views are shown of the body 40 of closure 10. The interior of base 42 defines an upper base sidewall or upper sidewall 48 and a lower base sidewall or lower sidewall 50. In specific embodiments, the upper sidewall 48 and the lower sidewall 50 are annular sidewalls. In specific embodiments, upper sidewall 48 is angled inwardly such that the diameter of upper sidewall 48 at the top of upper sidewall 48 is smaller than the diameter of upper sidewall 48 at the bottom of upper sidewall 48, nearest lower sidewall 50. A groove 52 is defined in upper sidewall 48. In specific embodiments, the groove 52 is an annular groove that extends circumferentially around upper sidewall 48. Upper sidewall 48 is configured to releasably engage fitment 20, such as by means of a snap fit connection, upon assembly of closure 10. An interior ledge 54 is defined between upper sidewall 48 and lower sidewall 50. Upon assembly of closure 10, ledge 54 further secures the fitment against axial dislodgement from the base 42 during dispensing, such as by an inverted shaking or pouring motion.
Lower sidewall 50 extends below ledge 54 and is configured to releasably couple with the neck of a container, such as by screwing onto and off from the container neck. Lower sidewall 50 defines one or more interior threads 46 configured to releasably mate with corresponding grooves defined along the exterior of a container neck. In certain embodiments, the lower sidewall of the base may alternatively define one or more interior grooves configured to releasably mate with corresponding threads defined along the exterior of the container neck. In the embodiment shown, lower sidewall 50 defines a single thread 46.
Referring to FIGS. 7-9 , various views of the fitment 20 of closure 10 are shown. The fitment 20 includes a dispensing face 22 that defines one or more dispensing apertures 24. In the embodiment shown, five circular dispensing apertures 24 of substantially the same size are shown arrayed across the dispensing face 22. In certain embodiments, the dispensing face may define a different pattern of dispensing apertures to meet different dispensing needs, such as to achieve a faster or slower dispensing rate or a broader or narrower dispensing range, or to accommodate larger or smaller particulates being dispensed. For example, in certain embodiments, the dispensing face may define greater than or fewer than five dispensing apertures, larger or smaller dispensing apertures, dispensing apertures spaced closer or further apart from one another, differently shaped dispensing apertures (e.g. ovular dispensing apertures), etc. Should a user's dispensing needs require an alternate dispensing face, the user may readily interchange the fitment 20, as described above, for a fitment having a dispensing face that better meets the user's current dispensing needs.
A circumferential sidewall 26 extends from dispensing face 22. The exterior geometry of sidewall 26 is configured to complement the interior geometry of upper sidewall 48, such that when closure 10 is assembled, sidewall 26 engages upper sidewall 48 of base 42. A flange 34 extends radially outwardly from the sidewall 26. When closure 10 is assembled, the flange 34 engages ledge 54 of base 42.
Referring to FIGS. 10-15 , additional views of assembled closure 10 are shown. When assembled, fitment 20 nests within base 42. Referring to FIG. 10 , a circumferential edge of the dispensing face 22 abuts upper sidewall 48 of base 42. In specific embodiments, as shown in FIG. 11 , the flange 34 engages at least a portion of the ledge 54 (shown in FIG. 6 ), specifically engages more than 50% of ledge 54, and more specifically engages more than 75% of ledge 54 (see also FIG. 17 ). As such, when the closure 10 is applied to a container and inverted for dispensing, ledge 54 serves as an additional barrier to groove 52 in upper sidewall of base 42 against dislodgement or decoupling of fitment 20 from base 42 during an inverted dispensing motion, such as shaking or sprinkling. In other embodiments, the fitment may not include a ledge, such as ledge 54, and may be secured to the base solely by the engagement between the exterior sidewall of the fitment and the upper interior sidewall of the base, such as the snap-fit engagement of lip 32 with groove 52.
Referring to FIG. 16 , a cross section of the closure 10 is shown, with fitment 20 secured within base 42 of the assembled closure 10. FIG. 17 shows an enlarged detail of the cross section shown in FIG. 16 . As shown in FIG. 17 , the exterior geometry of sidewall 26 complements the corresponding geometry of upper sidewall 48. The sidewall 26 includes an upper portion 28 and a lower portion 30. An edge, projection, or lip 32 is formed between upper portion 28 and lower portion 30. Lip 32 engages groove 52 defined in upper sidewall 48. Additionally, an upper surface 36 of the flange 34 engages ledge 54 of base 42.
FIGS. 18-19 show various views of the detail of FIG. 17 with fitment 20 removed to show groove 52 formed in upper sidewall 48 in greater detail. In specific embodiments, groove 52 is concavely rounded. FIGS. 20-21 show various views of the detail of FIG. 17 with base 42 removed to show lip 32 formed in sidewall 26 in greater detail. In specific embodiments, lip 32 is convexly rounded. In more specific embodiment, at an edge of upper portion 28 nearest lip 32, upper portion 28 protrudes farther in the radially outward direction than lower portion 30 at an edge nearest lip 32.
