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.
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: US 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); US 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).
US 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 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 1/16th to ⅛th 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.
