Wide-dispersal package and cap assembly
View Patent ↗A wide-dispersal package cap includes a rim and a domed portion formed within the rim and mounted thereto. The domed portion includes a plurality of orifices each having an internal opening and an external opening relative to a thickness of the domed portion. The orifices are formed spaced apart from one another through the domed portion at an angle, such that the external opening of a particular orifice is off-set from the corresponding internal opening, to thereby enhance wide-dispersal of contents of a package to which the cap is attached.
1. A method of providing wide-spread dispersal of a packaged substance, the method comprising the steps of:
providing a package containing a substance of powdered, liquid or granular form;
providing a cap on the package, the cap having a rim and a domed portion formed within the rim and mounted thereto;
the domed portion including a plurality of orifices each having an internal opening and an external opening relative to a thickness of the domed portion, said internal opening having a first centrally located axis and said external opening having a second centrally located axis, said first and second axis being generally parallel and offset from one another, such that the external opening of a particular orifice is off-set from the corresponding internal opening;
inverting the package; and
permitting the contents of the package to flow outwardly through the orifices of the cap.
2. A method of increasing flow-rate of material from a package, the method comprising:
providing a package containing a substance of powdered, liquid or granular form;
providing a cap on the package, the cap having a rim and a domed portion formed within the rim and mounted thereto; the domed portion including a plurality of orifices each having an internal opening and an external opening relative to a thickness of the domed portion, said internal opening having a first centrally located axis and said external opening having a second centrally located axis, said first and second axis being generally parallel and offset from one another;
inverting the package; and
permitting the contents of the package to flow outwardly through the orifices of the cap.
3. A wide-dispersal package cap comprises:
a rim; and
a domed portion formed within the rim and mounted thereto;
the domed portion including a plurality of orifices each having an internal opening and an external opening relative to a thickness of the domed portion, said internal opening having a first centrally located axis and said external opening having a second centrally located axis, said first and second axis being generally parallel and offset from one another such that the external opening of a particular orifice is off-set from the corresponding internal opening.
4. The wide-dispersal package cap of claim 3 , further comprising a closure portion connectable to the rim to thereby selectively cover the domed portion and prevent inadvertent release of package contents.
5. The wide-dispersal package cap of claim 4 , and further including a living hinge connecting the closure portion to the rim.
6. The wide-dispersal package cap of claim 4 wherein the rim includes a depression and the closure portion has a perimeter that overhangs the depression to thereby provide a thumb grip to facilitate opening the closure portion of the cap.
7. The wide-dispersal package cap of claim 4 , wherein the rim has a surface which faces the closure portion and the closure portion has a surface that faces the rim, the surface of the rim having an annular groove and the surface of the closure portion having a correspondingly shaped annular projection to detentingly connect to the annular groove and thereby permit the closure portion to be sealed to the rim.
8. The wide-dispersal package cap of claim 4 , wherein the rim has a surface which faces the closure portion and the closure portion has a surface that faces the rim, the surface of the rim having an annular projection and the surface of the closure portion having a correspondingly shaped annular groove to detentingly receive the annular projection and thereby permit the closure portion to be sealed to the rim.
9. The wide-dispersal package cap of claim 3 , wherein the rim has a side wall for connection of the cap to a package, the domed portion being disposed at one end of the side wall and an edge located on the end of the side wall opposite the domed portion.
10. The wide-dispersal package cap of claim 9 , wherein the edge is serrated to interact with a package to inhibit removal of the cap from the package, for child safety purposes.
11. The wide-dispersal package cap of claim 3 , wherein the domed portion is provided with a centrally disposed vent hole to permit entrance of air through the cap and into a package to which the cap is connected.
12. The wide-dispersal package cap of claim 3 , wherein the plurality of spaced-apart orifices are arranged in at least one circular pattern on the domed portion.
13. The wide-dispersal package cap of claim 12 , wherein the circular pattern of orifices is centered around a central axis of the domed portion.
14. The wide-dispersal package cap of claim 13 wherein the plurality of orifices are arranged in two circular patterns concentrically around the central axis of the domed portion.
15. The wide-dispersal package cap of claim 3 , wherein each orifice of the plurality of orifices is formed through a thickness of the domed portion so as to have an area of overlap between a first level at the internal opening and a second level at the external opening of the orifice.
16. The wide-dispersal package cap of claim 3 wherein the external opening of each orifice of the plurality of orifices is vertically offset toward the periphery of the domed portion relative to the position of the corresponding internal opening of the particular orifice such that when a package bearing the cap is inverted with the domed portion generally downward the external openings of each of the orifices are directed radially outwardly, to thereby enhance widespread dispersal of package contents.
17. A combination of a package for dispersal of material and a package cap, the cap comprising:
a rim; and
a domed portion formed within the rim and mounted thereto;
the domed portion including a plurality of orifices each having an internal opening and an external opening relative to a thickness of the domed portion, said internal opening having a first centrally located axis and said external opening having a second centrally located axis, said first and second axis being generally parallel and offset from one another such that the external opening of a particular orifice is off-set from the corresponding internal opening.
