DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to relates to two-way dispenser closures with openings of different cross-sections for dispensing the container contents at different rates.

The presently disclosed subject matter will now be described more fully hereinafter with reference to the accompanying drawings and examples, in which representative embodiments are shown. The presently disclosed subject matter can, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. The subject matter of our invention should be accorded the widest scope consistent with the features described herein. These embodiments are provided so this disclosure will be thorough and complete, and will fully convey the scope of the embodiments to those skilled in the art. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this presently described subject matter belongs.

As used herein the specification and the claims, the term “container”, also known as bottle, flagon, flask, jug or vial, an object that can be used to hold or transport liquids, solids, or gases. In the present invention, the container and the closure are independent entities.

The container closure described herein has several openings for dispensing fluids from the container at different rates. The closure has two parts, a cap and a pivotable top component. The cap has a base plate configured to seal the opening of the fluid container, and a pair of cylindrical tube apertures extending from the base plate which are in fluid communication with the contents of the container. The pivotable top component, moveable between a closed and two opened positions, is mounted on the cap for pivotable motion about a horizontal hinge axis and has a top plate and pair of dispensing pathways aligned with the cylindrical tubes of the cap. The dispensing pathways has cylindrical plugs (preferably hollow) extending from the top plate which are sized to sealingly engage the inner surface of the associated cylindrical tube of the cap, as well as cylindrical sleeves extending from the top plate being sized to sealingly engage the outer surface of the associated cylindrical tube of the cap. A pair of channels is formed by annular voids between the cylindrical plugs and cylindrical sleeves which lead to a pair of dispensing openings, wherein the dispensing openings are in fluid communication with the cylindrical tube and thereby the associated container. To allow for dispensing the container contents at different rates, the first dispensing opening and associated channel has a smaller cross section, perpendicular to a flow direction, than a second dispensing opening and associated channel

The two-way dispenser closure is designed to be attached to a container which contains a substance, preferably the top of the container. The substance may be a liquid including consumer products such as soaps, shampoos, sunscreens, lotions, cosmetics, and the like.

Referring now to the drawings wherein like reference numerals designate corresponding parts throughout the several views, FIG. 1 illustrates a side view of an embodiment of a fluid dispensing bottle 10 of the present invention. Dispensing bottle 10 includes a container 20 and a closure 30. Container 20 may be made of glass, metal, or plastic, in different shapes, colors, and sizes. Plastics include, but are not limited to, polyethylene terephthalate (PET), High-Density Polyethylene (HDPE), Polyvinyl Chloride (PVC), Low-Density Polyethylene (LDPE), or Polypropylene (PP). Plastics such as HDPE or LDPE are especially useful if dispensing bottle 10 is a squeeze bottle. A squeeze bottle is a type of bottle for dispensing a fluid, that is powered by squeezing the container through pressure exerted, e.g., by the user's hand. Its fundamental characteristic is that manual pressure applied to a resilient container is harnessed to compress fluid within it and thereby expel the fluid from the bottle.

Closure 30 has two parts, a cap 40 and a pivotable top component 60. FIG. 2 is an exploded perspective view of a first embodiment of a container closure 30, showing a pivotable top component embodiment 60, and a cap embodiment 40.

Pivotable top component 60, shown in perspective view in FIG. 2, and in bottom view in FIG. 3, has a top plate 61, a pivotable top component rim 65, a rocker arm 68, a pin 69, a first dispensing opening 86, and a second dispensing opening 96. Top plate 61 has a first surface 62 and a second surface 63. Pivotable top component rim 65 has a first surface 66 and a second surface 67. Protrusions 64 are disposed on second surface 67 of pivotable top component rim 65.

FIG. 3 also shows a first channel 84 and a second channel 94, as well as a horizontal hinge axis 70, cylindrical plugs 72a, 72b and cylindrical sleeves 76a, 76b. Cylindrical plugs 72a, 72b and cylindrical sleeves 76a, 76b extend from second surface 63 of top plate 61. The figure also shows that second dispensing opening 96 and associated second channel 94 have larger cross sections, perpendicular to a flow direction, than first dispensing opening 86 and associated channel first channel 84.

While the first channel 84 and second channel 94 are shown with substantially rectangular cross-sections, other cross-sections are contemplated including other quadrilateral forms (e.g., trapezoidal, square, and the like), triangular, continuous curves (e.g., circular, oval, and the like), and slots (having a width dimension substantially larger than a height dimension and with curved or substantially squared-off ends).

The cross-sectional area can be selected to dispense the contents of the container at a desired rate. For example, first dispensing opening 86 and associated channel first channel 84 may have a cross-sectional area of approximately 40% to 75% of a corresponding cross-sectional area of the second dispensing opening 96 and associated second channel 94. Preferably, the cross-sectional area of the first dispensing opening 86 and associated channel first channel 84 is approximately 60% to 70% of a corresponding cross-sectional area of the second dispensing opening 96 and associated second channel 94.

In one preferred embodiment, first dispensing opening 86 has a rectangular cross-section of 2 mm by 4 mm, and the second dispensing opening 96 has rectangular cross-section of 2 mm by 6 mm. Thus, the cross-sectional area of the first dispensing opening 86 is approximately 67% of a corresponding cross-sectional area of the second dispensing opening 96.

Horizontal hinge axis 70, as will be shown subsequently, provides the pivot axis for pivotable top component 60.

Cap 40, shown in perspective view in FIG. 2, in section view in FIG. 4, and in top view in FIG. 5, has an outer surface 41, an inner surface 42, a base plate 44, a rocker arm stabilizer 47, and a pin receiver 48. Protrusion guides 43 are blind holes disposed on inner surface 42 of cap 40. Rocker arm stabilizer 47, guides and limits the pivot path of the rocker arm 68, acting as a support point in the opening movement that releases first dispensing opening 86 and second dispensing opening 96. Base plate 44 has a top surface 45 and a bottom surface 46, a pair of cylindrical tubes 50a, 50b extending from top surface 45 of base plate 44, a container sealing ring 56, and a snap fit 57. Apertures 53a and 53b are defined by a cylindrical tube 50a and cylindrical tube 50b, respectively.

As seen in FIGS. 2 and 3, pivotable top component 60 includes protrusions 64 disposed next to each dispensing opening (86, 96). Cap 40 includes protrusion guides 43 disposed on cap inner surface 42. In this embodiment, protrusion guides 43 are racetrack shaped, having two lateral sides, and two vertical ends.

When cap 40 and a pivotable top component 60 are coupled together to form the closure 30, protrusions 64 are disposed inside their respective protrusion guides 43. The length of protrusion guides 43 is sufficient to allow the displacement of protrusions 64 during the movement of pivotable top component 60, and functions to provide guidance to the motion of pivotable top component 60. In addition, the end of the protrusion guides 43 are stop blocks when the pivotable top component 60 reaches its open position.

Closure 30 is designed to be attached to the top of container 20. Sealing ring 56 and snap fit 57 extend from bottom surface 46 of base plate 44. Snap fit 57 is the means of attaching closure 30 to container 20, and sealing ring 56 is a means of preventing leakage of the substance (e.g. liquid) disposed in container 20. Although a snap fit is described here as the means of attaching closure 30 to container 20, other means, such as screw threads or adhesives may also be used. The seal between closure 30 and container 20 may, in some embodiments, include a gasket.

Cylindrical tubes 50a, 50b extending from top surface 45 of base plate 44, each have an outer surface 51a and 51b, respectively, and an inner surface 52a and 52b, respectively. Cylindrical tubes 50a, 50b, as mentioned above, define a pair of apertures 53a, 53b through base plate 44. Apertures 53a, 53b are in fluid communication with the contents of container 20.

FIGS. 6 and 7 show views of the first embodiment of assembled closure 30. FIG. 6 is a section view of assembled closure 30, and FIG. 7 is a top view of assembled closure 30 when closure 30 is in the closed position. The figures show cylindrical plugs 72a, 72b which extend from second surface 63 of top plate 61, are sized to sealingly engage inner surfaces 52a and 52b, respectively, of the associated cylindrical tubes 50a, 50b of cap 40. Cylindrical sleeves 76a, 76b, which also extend from second surface 63 of top plate 61, are sized to sealingly engage outer surfaces 51a and 51b, respectively, of the associated cylindrical tubes 50a, 50b of cap 40. The result is that when closure 30 is in the closed position, there is no pathway for the substance disposed in container 20 to be dispensed from fluid dispensing bottle 10.

FIGS. 8 and 9 show section view of the first embodiment assembled closure 30. FIG. 8 is a section view of assembled closure 30 when closure 30 is in a first opened position. FIG. 9 is a section view of assembled closure 30 when closure 30 is in a second opened position. In each opened position, pivotable top component 60 has been pivoted about horizontal hinge axis 70. In the first opened position, the pivot is in the clockwise direction, while in the second opened position, the pivot is in the counterclockwise direction.

In FIG. 8 (the first opened position), cylindrical plug 72a, which is associated with first channel 84 and first dispensing opening 86, has been displaced so that cylindrical plug 72a is no longer sealingly engage with inner surface 52a of cylindrical tube 50a. Cylindrical sleeves 76a, 76b remain sealingly engage with outer surfaces 51a, 51b of cylindrical tubes 50a, 50b, respectively. Also, cylindrical plug 72b associated with second channel 94 and second dispensing opening 96, remains sealingly engage with inner surface 52b of cylindrical tube 50b. First annular void 82 is formed. The result is that when closure 30 is in the first opened position, first dispensing pathway 80 is created, and the substance disposed in container 20 passes through first channel 84 and is dispensed from fluid dispensing bottle 10 through first dispensing opening 86.

In FIG. 9 (the second opened position), cylindrical plug 72b, which is associated with second channel 94 and second dispensing opening 96, has been displaced so that cylindrical plug 72b is no longer sealingly engage with inner surface 52b of cylindrical tube 50b. Cylindrical sleeves 76a, 76b remain sealingly engage with outer surfaces 51a, 51b of cylindrical tubes 50a, 50b, respectively. Also, cylindrical plug 72a associated with first channel 84 and first dispensing opening 86, remains sealingly engage with inner surface 52a of cylindrical tube 50a. Second annular void 92 is formed. The result is that when closure 30 is in the second opened position, second dispensing pathway 90 is created, and the substance disposed in container 20 passes through second channel 94 and is dispensed from fluid dispensing bottle 10 through second dispensing opening 96.

As mentioned earlier second dispensing opening 96 and associated second channel 94 have larger cross sections, perpendicular to a flow direction, than first dispensing opening 86 and associated channel first channel 84. This allows for more substance to be dispensed from fluid dispensing bottle 10 when closure 30 is in the second opened position than when it is in the first opened position. If dispensing bottle 10 is a squeeze bottle, then a similar amount of manual pressure applied to container 20 yields more substance from fluid dispensing bottle 10 when closure 30 is in the second opened position than when it is in the first opened position.

In some embodiments, indicia may be disposed on first surface 62 of top plate 61 of pivotable top component 60 near first dispensing opening 86 and second dispensing opening 96 to indicate that more substance will disperse from fluid dispensing bottle 10 when closure 30 is in the second opened position than when it is in the first opened position.

FIGS. 10 and 11 show views of an assembled second closure embodiment. FIG. 10 is a section view of an assembled closure 130 in the closed position, while FIG. 11 is a section view of assembled closure 130 in a first opened position.

Aperture 153 is defined by cylindrical tube 150.

Sealing ring 156 and snap fit 157 extend from bottom surface 146 of base plate 144. Snap fit 157 attaches closure 130 to a container, and sealing ring 156 prevents leakage of the substance (e.g. liquid) disposed in the container. Although a snap fit is described here, screw threads or adhesives may also be used to attach closure 130 to a container, and the seal between closure 130 and the container may, in some embodiments, include a gasket.

Cylindrical tube 150, extending from top surface 145 of base plate 144 has an outer surface 151 and an inner surface 152. Cylindrical tube 150, as mentioned above, defines an aperture 153 through base plate 144. Aperture 153 is in fluid communication with the contents of the container.

The pivotable top component portion of cap 140 has a top plate 161, a pivotable top component rim 165, a pin 169, a first dispensing opening 186, a first channel 184 and a second channel 194. The pivotable top component also has a rocker arm and a second dispensing opening (not shown).

Top plate 161 has a first surface 162 and a second surface 163. Cylindrical plug 172 and cylindrical sleeve 176 extend from second surface 163 of top plate 161.
