(en)CROSS-REFERENCE TO RELATED APPLICATION
This is the Regular U.S. Application corresponding to and claiming priority from U.S. Provisional Application Ser. No. 62/144,200 filed by the same inventors under the same title on Apr. 7, 2015, priority of which is claimed under 35 USC §§119, ff.


FIELD
This application relates to the portion dispensing field, and more particularly to universal apertured tube or bottle top assemblies having a flip, pop-up or twist-type closure in which is disposed an integrated LED light. The inventive tube/bottle top assemblies also include a battery power source and switch wherein the LED light is automatically turned-ON when the cap is actuated to open the aperture for portion dispensing. For a flip-lid, the LED light is located on the underside of the flip-lid, which upon opening is then automatically oriented to point both in the direction of dispensing of the bottle contents out of the bottle-top aperture and to point at the surface location on which the dispensing is directed, in order to illuminate the target area so that the contents are accurately disposed directly from the container in terms of target location and amount. In the pop-up and twist type cap assemblies, the LED is located on the exterior of the cap top, pointing in the direction of the target area. Actuating a movable cap member causes communication of a dispensing channel from the interior of the cap to the exterior and also closes a circuit contact to turn the LED light ON. In all these embodiments, closing the lid or the dispensing conduit, functions to turn OFF the LED.
BACKGROUND
There are a number of proposals for having lights incorporated in the lids or caps of containers, only a few of which have achieved commercial status. Most of the proposals have the lights pointing down into the container contents for a variety of purposes, primarily to illuminate the level of the contents in the container, for novelty, or for use of the contents to scatter light to the area on which the container is resting as a surrogate for a source of area lighting.
Examples are found in: U.S. 2011/0188229 A1 (Hernandez); U.S. Pat. No. 6,454,432 B1 (Avinger); and CN 203173075 U (Yu, 2013). Others, less pertinent, are: U.S. Pat. No. 5,311,413 A (Farmer); U.S. 2014/0071663 A1 (Callanan), see also http://www.thinkgeek.com/product/b4ad/; US 2005/0007773 A1 (Austin); U.S. Pat. No. 7,976,177 B2 (Dikopf); U.S. Pat. No. 7,740,368 B2 (Chiang); U.S. Pat. No. 7,040,776 B2 (Harrell); U.S. Pat. No. 5,178,450 A (Zelensky); and GB 2507293A (Ball, 2014).
U.S. 2014/0071663 is representative of the idea of incorporating LED lights in the lid pointing down to the container contents in order to scatter light. In its commercial embodiment, the lid includes a hanger, and the container is designed to hold potable water. See: http://www.tree-hugger.com/gadgets/self-filtering-water-bottle-also-acts-flashlight.html. When the LED lights are switched ON, the light directed into the water scatters. When the container is hung from a tent pole, the light is used to illuminate the tent. Of course, when the container is unscrewed from the lid, there is no scattered light effect, and that effect varies widely depending on the level of fluid in the container.
In many direct dispensing situations, particularly in low light or dark environments, it is important to dispense the contents of the container in a specified direction or area directly from the container without use of an intermediary tool, such as a brush or applicator wand (e.g., as in an iodine bottle). An example is dispensing liquor at bars, which normally have low ambient lighting. Another is dispensing oil or grease while doing repair work on a vehicle where overhead illumination is shielded by the hood of the vehicle. Still another example is dispensing glue while working on models. Other examples involve doing close work such as in electronics and the jewelry or watch-making trades. In those cases the worker or artisan's body shields the target area being worked-on from overhead illumination. Still another example is application of personal care products and medicaments, such as application of lubes, emollients, lotions or medications to targeted areas on the skin. In all these cases, proper illumination may be required which currently necessitates two-handed operation, one to hold a flash-light and the other to do the dispensing. However, in many cases one hand may be needed to do the dispensing and the other is otherwise occupied, such as by holding a tool, thereby not having a free hand available for also holding a light. Calling on another person is difficult, as the person working continuously has to direct the other person where to point the light, and more often the person holding the light cannot see the target area on which light is to be directed, or the worker or tool is in the way.
This need is well recognized, and the solution to date has been to provide a head-lamp or a light on the tool. Head lamps in many situations are unsuitable, require frequent adjustment as a result of aiming too high or low, interfere with head gear and may not give the target area good illumination. While lights integrated into tools are helpful, they clearly cannot be used in cases of dispensing applications.
Some cosmetics, such as lipstick, lip gloss, fingernail polish and teeth whitening gel are packaged in containers that use brushes for application. Lights have been incorporated in the brush-holder portion of the packaging to provide light at the tip of the brush when painting the cosmetic or polish. See, 2013/0176717. These applications do not involve direct dispensing from the container; rather they use an intermediary brush, wand or nozzle, and pose rather different problems.
Accordingly, there is a long felt and unmet need in the direct-from-the-container portion dispensing field for a solution to target area illumination during direct portion dispensing which frees a hand from holding a light while dispensing contents from a tube or bottle, is not interfered-with or occluded, is automatic ON/OFF, and is universally adapted to any type of direct portion dispensing container.
The Invention
SUMMARY
The invention is directed to universal tube or bottle top assemblies having actuatable closure lids in which is disposed an integrated LED light, which assemblies are adapted to cooperatingly engage direct-portion-dispensing containers.
In a first, flip-cap embodiment, the inventive tube/bottle cap assemblies comprise a two-part cap assembly, a lower portion that removably engages a portion dispensing container and which includes an aperture for dispensing product contents retained in the container. The second part of the cap assembly includes a flip-lid that is hinged to the lower portion, typically via a “butterfly-type” living hinge. The flip-lid typically includes a closure plug that is aligned with the dispensing opening in the lower section or portion of the cap assembly.
At least one LED light is disposed on the inner surface of the flip-lid so that it is hidden when the lid is closed. The LED(s) is/are located so as to not interfere with the aperture or the closure plug. The cap assembly also includes a battery power source and switch wherein the LED light is automatically turned-ON when the lid is flipped-open and OFF when closed. The LED light, being located on the underside of the flip-lid, upon opening of the lid is then automatically oriented to point light in the direction of dispensing of the bottle contents out of the bottle-cap aperture and to illuminate the surface location on which the dispensing is directed. The result is that the target area is clearly and adequately illuminated so that the contents are dispensed accurately in terms of target location and amount.
It should be understood that in alternative embodiments of the inventive assembly, the battery can be located in either the lower portion or the upper flip-lid portion of the cap assembly, or in the alternative one battery in each portion. In a first embodiment, the battery is located in a sealed section of the lower cap portion or section, and the wires leading to the LED in the flip-lid include a pressure contact switch that is in the NO state. That is, the switch elements are separated to insure the circuit is Normally Open, when the flip-lid is closed so that the light is OFF. Upon flipping the lid to the open position, pressure is released that holds the switch contacts apart, they spring back into contact with each other, closing the circuit to the ON condition, so that the battery energizes the LED, causing it to light up. In another embodiment, a contact may be embedded in the hinge of the flip-lid so that upon opening, the circuit goes Closed and the LED is activated ON. One skilled in this art will recognize that a wide range of suitable switch arrangements can be employed to effect the principles of the invention: that upon opening the flip-lid portion of the cap, the LED is energized to provide light.
In still another, alternative version of the flip-lid cap embodiment, the entire assembly of LED, battery and switch may be enclosed in the lower cap with the LED spaced from the dispensing aperture and pointing outward, that is, toward the direction of dispensing. The flip-lid portion may include a projection or plunger that presses on a portion of the upper surface of the lower cap so as to cause a leaf switch element to an NO state (OFF), preventing the LED from lighting when the lid is closed. Upon release of the lid, that is, opening it, the pressure is released, the circuit goes to the NC state (ON), and the LED lights up.
The lower portion of the flip-cap assembly may include threads for removably engaging a container. Thus, in accord with one aspect of this invention the cap assembly is universal, in that a set of standard cap sizes are produced to screw-onto matching standard containers. The invention thus includes the combination of the inventive cap assembly and a container to which it is threadedly mated, and into which any desired product may be retained. The inventive combination of cap light assembly and matching container may be provided, or individual cap assemblies having the inventive light system may be provided for after-market retrofit on tubes or bottles of product previously purchased by a user. Thus, for example, a homeowner, craftsman, artisan or tradesman may purchase a suite of the inventive cap assemblies of varying diameter for, or for retrofitting on product bottles already in his or her possession.
In second and third embodiments, the inventive target-illuminating cap light assembly of this invention is applied to both “pop-up” and “twist” type caps. A pop-up cap is one in which a top surface or lid assembly of the cap is pivotable on opposed edges (e.g., looking at the cap from above, the left and right edges include pivot members such as bosses). Pressing down on the movable top at a location 90° from the pivot (that is, seen from above, a back edge), causes that edge to depress, and the opposite edge to rise (that is, seen from above, a front edge), revealing a dispensing aperture. Typical commercial uses for pop-up caps are on shampoo bottles or body gels. These types of caps are ideal for one-handed operation. In this embodiment, the pop-up movable cap top includes an LED light facing outwardly and forwardly (toward the front edge). Depressing the back edge not only raises the opposed dispensing aperture, but it also closes the circuit to automatically power-ON the LED by a battery contained in the cap or lid assembly and illuminating the target area when the bottle is tilted to effect dispensing. The light being ON functions as a reminder to the user to close the cap by pressing on the edge adjacent the revealed dispensing aperture (front edge). After dispensing, closing the bottle by pressing on the front aperture edge automatically opens the circuit, turning off the light.
In one implementation of this embodiment, the pivoting lid assembly includes a lower recessed member (shallow cup) that contains the battery and circuit and an LED facing forward. This recessed member includes a vertical side wall, or dispensing direction portion of that side wall, that is made of transparent or translucent plastic. The LED, when ON is able to shine light through the plastic so as to illuminate the dispensing stream and the target area. The cup is closed by a lid member sealing the battery, circuit board and LED inside the hollow lid volume.
A third embodiment employs the inventive cap light assembly integrated into twist-type caps. Twist-type caps have an external dispensing aperture that is not covered by a closure. Rather, internal to the cap is a horizontal gate or valve assembly which, upon rotation of the cap with respect to the tube or bottle on which it is mounted, unblocks or blocks (depending on the direction of rotation) the dispensing channel from the interior of the cap to the external aperture. Typically a 1/16 th to ⅛ th rotational turn is all that is needed to open the valve to permit dispensing. Commercial uses include cosmetics, hair preparation and styling gels. As adapted with the inventive assembly, a twist-type cap includes an LED exposed on the exterior top of the cap. Rotation of the cap not only opens the conduit, but also closes the circuit to illuminate the LED by a battery included in the cap assembly. Counter-rotation turns off the light. The light being ON also functions in this embodiment as a reminder to close the container by rotating the cap.
While four principal embodiments are described herein, one skilled in this art will recognize that the principles of the invention may be applied in a straightforward engineering sense to a wide variety of cap types, functional operation and design, such that the invention is intended to cover such additional embodiments and adaptations. For example, it should be clear that various colors of LEDs may be used, for example red light in use environments where dark vision adaptation is to be preserved, such as photo labs. Where higher illumination levels are needed, and/or good color discrimination is required, such as in medical dispensing applications or tatooing, white LEDs may be used. Likewise, white LEDs may be used in bars for clarity in dispensing liquor. Different colors of LEDs may be used on an array of related liquids to be dispensed so that the user quickly learns to recognize that the wrong liquid is in hand because the light is not the correct color before dispensing, and the error caught.

DETAILED DESCRIPTION OF THE INVENTION
The following detailed description illustrates the invention by way of example, not by way of limitation of the scope, equivalents or principles of the invention. This description will clearly enable one skilled in the art to make and use the invention, and describes several embodiments, adaptations, variations, alternatives and uses of the invention.
In this regard, the invention is illustrated in the several figures, and is of sufficient complexity that the many parts, interrelationships, and sub-combinations thereof simply cannot be fully illustrated in a single patent-type drawing. For clarity and conciseness, several of the drawings show in schematic, or omit, parts that are not essential in that drawing to a description of a particular feature, aspect or principle of the invention being disclosed. All publications, patents and applications cited in this specification are herein incorporated by reference as if each individual publication, patent or application had been expressly stated to be incorporated by reference.
FIG. 1 illustrates a first embodiment of the inventive cap light and dispensing bottle assembly 10 . The cap assembly 12 is retained on dispensing container 14 that retains fluid composition 16 to be dispensed by the user. The lower dispensing portion 18 of the cap includes inner threads 20 that engage the threaded neck of the container 14 and a spout or aperture 22 that has a bore or lip 23 through which the fluid contents 16 of the bottle may be dispensed when the container is inverted. The cap assembly 12 also includes an upper lid portion 24 that is connected to the lower threaded dispensing portion 18 via a hinge 26 , in this example a living hinge of the butterfly type. The upper lid portion 24 includes at least one LED 28 and a battery compartment 30 , containing battery 36 plus necessary circuitry (not shown) including an ON/OFF switch automatically activated by opening and closing the lid 24 portion. The LED(s) are positioned on the inside surface of the upper lid portion 24 of the cap so that when the lid is opened, the circuit is closed causing the LED(s) to light up. An important aspect of the invention is that when the lid portion 24 is in the open position as shown in FIG. 1 , the LED(s) point at the target area for dispensing of fluid 16 so that the target area is illuminated. The LED(s) are not oriented to illuminate the contents 16 of the container 14 , nor are they intended-to. Finger notch 32 , assists in opening the lid section 24 . Interior contour 34 of the lid may include a projection 36 that serves to close the dispensing bore 23 when the lid is in the closed position.
FIG. 2 illustrates the cap assembly 12 , from the position of the butterfly living hinge 26 . The cap assembly lower dispensing portion 18 is threaded on the container 14 . The upper lid 18 is closed on the lower portion 18 , and shows the arrangement of the LEDs projecting from the inner surface of the lid 24 , and having a centrally located battery compartment including a battery 36 with the appropriate circuitry including lid-actuated pressure switch (as described above) to power the LEDs.
FIG. 3 illustrates the cap assembly 12 in the open position, top view. The LEDs in the lid portion 24 in this embodiment are positioned in an array around the central aperture plug 36 , and the battery 38 is centrally located in its compartment in the lid. When the lid is opened, the LEDs are pointing in the same general direction as the pour spout 22 , so that when the container is inverted and the bottle squeezed to dispense the bottle fluid contents, the light will be pointing at the target area for deposit of the dispensed fluid. It should be clear that while in this embodiment, four LEDs are shown, as few as one may be all that is necessary to provide suitable level of illumination, depending on the battery size and the efficiency of the LED element.
FIG. 4A and FIG. 4B show a two position lid version of the flip-lid embodiment of FIGS. 1-3 . In FIG. 4A , the contents will be dispensed in the direction shown by Arrow A when the bottle is inverted. When the lid 24 is opened to a first position, FIG. 4A , the LEDs (in this embodiment, two are shown) will be pointing in a direction shown by the Arrow B. The arrows converge generally at the target area C. In FIG. 4B , the lid can be opened to a second position and the area of convergence is farther away.
FIGS. 5A-C are to be considered together. They show a second embodiment of the inventive cap light assembly 10 , in which the cap 12 is dome-shaped. The lid is hinged at the back side as before. FIG. 5B shows the battery located in the lower, threaded cap portion 18 . The circuit 40 (shown schematically and in part as the drawing does not permit the detail that will be straight-forward to one skilled in this art) includes a switch assembly 42 disposed just below the upper, flexible surface of the cap, as shown. This switch 42 is activated from a NC state when the lid 24 is closed, to an NO state when the lid 24 is opened by means of a circuit breaker finger 44 . As shown in FIG. 5B the finger is located on the forward edge of the lid, opposite the hinge (see FIG. 5C ). In FIG. 5B the LED is shown in alternate positions, at 28 on the underside of the lid, and at 28 ′ on the top surface of the lower dispensing portion of the cap. The dispensing spout 22 and its closure plug 36 are also illustrated. FIG. 5C illustrates the cap assembly of FIG. 5B in which the cap is now fully opened so that the LED, either in the lid at 28 , or on the top surface of the lower portion at 28 ′ is directed to the target area on which fluid 16 is dispensed from the container 14 . Note in this alternative of this embodiment, the battery 38 is disposed in the domed lid, the switch 42 is located adjacent the hinge 26 in the lower portion 18 , and the actuating circuit breaker finger 44 is located adjacent the hinge on the lid, as shown. For details of an exemplary switch assembly, see FIGS. 7A and 7 B.
The FIGS. 6A-D drawings are to be considered together. They show still another embodiment of the inventive cap light assembly, in this case adapted for use with a “Pop-Up” type dispensing cap assembly. In this embodiment the lid portion of the cap assembly 12 comprises a disk-shaped pop-up cap element 46 that is pivoted on diametrically opposed bosses 48 having a common center-line CL of pivot. Upon pressing down on an area of the disk 46 opposite the spout area 22 , the bore 23 of the spout is raised permitting dispensing; this is best seen in FIGS. 6B and 6C . As shown in FIG. 6B , pressing down on the area marked “PRESS” (see FIGS. 6A, 6B and 6D ) closes the switch 42 , causing the LED to illuminate. The battery (not shown) may be located in any convenient place, such as in the disk 46 in the “PRESS” area, or vertically adjacent the threaded portion 20 of the lower portion of the cap 18 . The LED 28 is disposed in a raised hood portion 50 of the disk element 46 . FIGS. 6C and 6D clearly show that when the disk is pressed downwardly ( FIG. 6B ), the opposite end is raised above the lip of the lower cap portion 18 exposing the nozzle 23 , and the LED 28 disposed in the hood is pointed in the same direction as dispensing, even though the dispensing is orthogonal to the bottle neck 20 . Thus, the LED will illuminate the target area on which the fluid from bottle 14 will be dispensed. FIG. 6D shows a recess 62 in the outer wall of the cap lower portion 18 to facilitate pressing down on the disk element 46 . The recess 62 permits pressing with the pad of the finger, that is, the finger can be oriented horizontally, to effect full depression of the disk 46 to insure activation of the switch 42 ( FIG. 6B ).
FIGS. 7A and 7B show one example of a switch that advantageously may be used in the lighted cap assembly of the invention. In FIG. 7A , the cap lid 24 , 46 (depending on embodiment) is closed as indicated by Arrow C, in which case the circuit actuating finger 44 presses down on a flexible area 18 ′ of the top of the lower portion 18 of the cap 12 . The switch assembly in this exemplary embodiment includes a flexible or pivoted leaf 52 that is pushed out of contact with the opposite lead 54 by the action of finger 44 , as shown, thus putting the switch in the Normally Open, NO, state, in which case the LED is dark. In FIG. 7B , when the lid 24 , 46 is opened as indicated by Arrow O, pressure is removed from the area 18 ′ and the leaf 52 springs up to contact the other lead 54 , completing the circuit and energizing the LED to light up.
FIGS. 8A and 8B show another embodiment in which the cap assembly 12 includes an openable split or segmented lid portion 24 ′. In this embodiment, one or more LED(s) is/are disposed adjacent the central openable segment 24 ′ on the outer top surface of the cap, as at 28 . The segment 24 ′ may be opened by engaging a lip or fingernail notch 32 . In FIG. 8B the segment has been opened at hinge 26 and the LED lights up as the pressure from finger 44 has been relieved from the surface 18 ′ (see FIGS. 7A and 7B above). The spout 22 is now exposed for dispensing via its bore 22 from the container 14 . The LED 28 is directed to the target area and illuminates it for dispensing.
FIGS. 9-11 show another implementation of the third, Pop-up embodiment of the inventive cap assembly. FIG. 9A shows a Pop-up cap assembly 10 comprising bottle closure (cap) 12 in which the pivotable assembly 46 is housed. As shown, the pivoting member is in the OFF (circuit NO), closed position so that no contents of a bottle (not shown, but see FIG. 6B ) can be dispensed via lip 22 . In FIG. 9B the finger press area 74 of the back of the pivoting assembly 46 is depressed downwardly (see FIG. 6B ) and the assembly 46 pivots down, exposing the conduit 23 b that communicates with the interior of the bottle in order to permit dispensing of contents via the lip 22 . This is the ON position (circuit NC) so that the LED, positioned inside the assembly 46 shines light through the clear side wall area 76 , thus illuminating both the contents dispensing and the target area.
FIGS. 10A and 10B show the internals of the cap assembly 10 , showing the bottle threads 20 , the dispensing tube 23 a communicating from the inside of the bottle (not shown, see FIG. 6B ) yet not aligned with external dispensing conduit 23 b and closed-off by plug 36 . As seen in FIG. 10A , the pivotable assembly 46 comprises a lower, cup member 46 a (best seen in FIG. 11 ) which contains the LED 28 , battery 38 and circuit board 40 . A switch actuator 44 is spaced from a flexible diaphragm (gasket) so that the circuit board switch is open, and the LED 28 is OFF. In FIG. 10B , finger pressure on area 74 presses the back of the assembly 46 down, raising the plug from off the top of the tube 23 a and permitting connection to dispensing conduit 23 b. This permits dispensing contents out of the container via the lip 22 . At the same time projection 44 engages the diaphragm that pushes up to close the switch on the circuit board 40 , causing the battery 38 to energize the LED 28 . Since the side wall of the cup 46 a is transparent or translucent, the LED light shines on both the contents as delivered out of the container and on the target area onto which the contents are dispensed.
FIG. 11 shows the several parts of the cap assembly 10 in an exploded view, including the lower cap base containing the threads (see FIGS. 10A and 10B ) and the vertical tube 23 a. This view also shows the notch 62 at the back of the cap which permits pressing down on the lid 46 b at area 74 to pivot the assembly 46 . The front lip 22 is also shown. The pivoting Pop-up assembly 46 comprises lower cup 46 a, which includes a recess volume 30 formed by an upstanding perimeter wall, at least the front portion of which 76 is transparent or translucent. The circuit board assembly 40 , containing the battery, circuit, ON-OFF switch and LED is received in the recess 30 , and the top closed by a generally planar lid 46 b which may be ultrasonically sealed to the inner surface of the upstanding side wall adjacent the top. That is the circuit board assembly 40 , including battery and LED are sealed in the pivoting Pop-up assembly 46 , preventing leakage of fluid contents into contact with the circuit assembly 40 and shorting it out. The bottom surface of the cup 46 a includes an aperture 80 that is sealed with the flexible diaphragm 78 . Diaphragm 78 includes a central knob as shown to engage the switch on the circuit board 40 when actuated by the actuator 44 (compare FIGS. 10A and 10B ). The diaphragm 78 also serves as a gasket to seal the aperture 80 . Thus the entire Pop-up assembly 46 is sealed.
INDUSTRIAL APPLICABILITY
It is clear that the inventive cap light assembly of this application has wide applicability to the fluid dispensing industry, usefully so in the medical, personal care and personal hygiene fields. The inventive cap assembly provides additional functionality to a dispensing bottle, permitting one-handed use for targeted application of dispensed fluids in low light environments.
