    • BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • This invention relates to dispensing closures that one would utilize in sprinkling solid particulate such as spices or mixtures of spices.
  • 2. Description of the Related Art
  • Dispensing closures for spice containers traditionally depend on the underside of its lid having projections that close off the orifices when the lid is in the sealing or storage mode. Such arrangements, although theoretically functional, are not practicable owing to the plurality of orifices and cooperating projections that require precise alignment to make sealing effective. Additionally, frequently there is entrapment of residual particles between the lid and the web. As a result, the projections cannot mesh precisely within the orifices to accomplish a true seal. This problem is especially prevalent among mixtures of spices that contain salt, and accordingly are hygroscopic—the particulate then may agglomerate and clog the orifices, preventing the spices from being freely dispensed. Furthermore, any inadequate sealing will permit moisture from ambient humidity to enter the container and agglomerate the particulate inside. In some cases oxygen combined with humidity may promote degradation of the contained product.
    • OBJECT OF THE INVENTION
  • It is an object of the present invention, therefore, to provide a new and improved sealing efficacy of hinged covers over the web that contains the dispensing orifices of the spice container.
    • SUMMARY OF THE INVENTION
  • As will become clear from the following description, the spice dispensing closure of the invention provides a circumferential valve seal between the underside of the lid and the orifice-containing web to prevent moisture from entering. As will be seen, the seal is so designed that no components of the lid and the web are able to contact one another to prevent the efficacy of the valve seal which follows. The seal is enabled even should there be an inclusion of particulate between the lid and the web.
  • In a first embodiment of the invention, a male member of the seal extends downward from the lid and circumvents the center of the lid near its extreme circumference. A female cooperating member is located in the web to receive the male member.
  • In a second embodiment, a second valve seal arrangement is presented in which the location of the male and female cooperating components are reversed—the male portion being located within the dispensing web, and the female component being located within the underside of the lid.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • These and other features of the present invention will be more clearly understood from a consideration of the following description, taken in connection with the accompanying drawings, in which:
  • FIG. 1 is a top view of the spice dispensing closure of the invention with its lid fully opened to 180°;
  • FIG. 2 is a lateral view of the closure cross-sectioned through its center without the lid in place;
  • FIG. 3 is a lateral view of the cross-sectioned closure with the lid opened to approximately 135°;
  • FIG. 4 is a lateral view of the cross-sectioned closure with the lid fully opened to substantially 180°;
  • FIG. 5 is a lateral cross-sectioned view of the spice dispensing closure of the invention with the lid in a closed, or sealed, orientation;
  • FIG. 6 is a detail helpful in an understanding of the snap-lock operation of the embodiment of the invention shown in FIGS. 1-5; and
  • FIG. 7 is a lateral cross-sectioned view of a second embodiment of the invention in a closed, sealed orientation, utilizing a double valve seal.
    • DETAILED DESCRIPTION OF THE INVENTION
  • In FIGS. 1 through 6, a circular lid or cover for the dispensing closure 10 is shown at 12 joined by a toggle hinge 14 to a cylindrical cap 16. The dispensing orifices in a circular web 28 are illustrated at 18, 20—with reference numeral 22 identifying a male snap-lock projection member extending downwardly from the underside of the lid 12 and with reference numeral 24 representing a female snap-lock well, extending downwardly in the web. A further orifice 26 is provided in the snap-lock well 24 to prevent any spice product from collecting there, falling instead into a cylindrical spice container or bottle beneath (not shown).
  • In the lateral view of FIG. 2, the wall of the cap 16 is shown at 30, a female valve seat encircling the web 28 is shown at 32, and a continuous thread for joining with the spice container or bottle is illustrated at 34. Reference numeral 36 identifies an injection mold gate for forming the dispensing closure of plastic.
  • (As previously noted, FIG. 1 represents a top view of the dispensing closure with its cover-lid 12 fully opened to substantially 180°, while FIG. 2 is a lateral view only of the cap 16, cross-sectioned through its center.)
  • As the lateral cross-sectioned views of FIGS. 3, 4 and 5 illustrate a male valve seal ring 40 extends downwardly from the underside of the cover-lid 12 near its extreme circumference 15 (see FIG. 1), and is configured to fit within the female valve seat 32 encircling the web 28 to which it is joined. As FIGS. 3-5 illustrate, the male snap-lock projection member 22 is configured to fit within the female snap-lock well 24, and a locking ring 44 within the well 24 retains the male member in place. Closing the lid 12 locks the male and female members 22, 24, and seals the ring 40 within the seat 32. Reference numeral 42 identifies a finger detent for then opening the cover-lid 12, and reference numeral 46 identifies a stacking ring on the top side of the lid 12 for arranging the closure for storage.
  • As will be understood, the orifices 18-20 of FIG. 1 are of different size for dispensing spices of different diameters or characteristics. The hinge 14 is constructed in three dimensions to give to it a toggle action as the cover-lid 12 opens and closes. The product passage orifice 26 within the female locking well 24 allows passage of the product back into the dispensing container should there be a tendency of particulate to build up within the well. The continuous thread 34 is in the nature of a screw thread for attaching the dispensing closure to the container or bottle. The circumferential valve seal formed by the ring 40 within the seat 32 between the underside of the cover-lid 12 and the web 28 prevents any component of the lid and web contacting one another to affect the efficacy and positive nature of the seal. The snap-lock that maintains the closure when the cover-lid 12 is depressed prevents any moisture from getting into the container and agglomerate the spices or mixtures of spices within. FIG. 6 is helpful in an understanding of the snap-lock operation.
  • In the configuration shown in the lateral cross-sectioned view of FIG. 7, a second female valve seat 50 is illustrated along with a second male valve seal ring 52. With all other component parts remaining the same, the male seal ring 52 will be understood to extend upward from the web 28 and the female valve seat 50 will be understood to be located within the underside of the lid 12 to provide a second seal encircling the seal formed by the ring 40 within the seat 32. This is just the opposite with respect to the orientation of FIGS. 1-5. With this arrangement, an even increased positive seal results.
  • While there have been described what are considered to be preferred embodiments of the present invention, it will be readily appreciated by those skilled in the art that modifications can be made without departing from the scope of the teachings herein. For at least such reason, therefore, resort should be had to the claims appended hereto for a true understanding of the scope of the invention.
