Abstract
The present discussion generally describes a liquid fuel burning device such as an oil lamp having a reservoir for holding the liquid fuel and a flange substantially covering the liquid fuel holding area of the reservoir. The flange is sized and located to provide an opening between a perimeter of the flange and an inner surface of the reservoir. The opening permits a level of the liquid fuel to be monitored and/or checked during filling of the reservoir. Thus, the chance of having an overflow of liquid fuel or an under-filled reservoir is substantially reduced. The flange is configured with a downward slope to allow liquid fuel to drain toward the opening, if liquid fuel gets on the flange during filling of the device.
Description
- 1. Technical Field
- This disclosure is generally related to a lamp device that burns a combustible substance by drawing the substance up through a wick, for example an oil lamp.
- 2. Description of the Related Art
- Candles, gel pots, and oil lamps are commonly used as decorative light sources and can also be used to disperse fragrances. These light sources typically produce a yellow flame by burning a combustible substance (e.g., wax, gel, oil, etc.), which is continuously drawn up through a wick by capillary action. In the case when a wax or gel is used as the combustible substance, the heat of flame melts a small pool of the wax in the vicinity of the wick stem to allow the melted wax to be drawn up through the wick.
- Unlike candles or gel pots, the oil in an oil lamp is already in a liquid state and does not need to be heated by the flame to invoke capillary action. The liquid form of the oil, however, makes an oil lamp more susceptible to spillage of the oil either during use or during refilling of the oil. Typically, the oil is held in a container and the only access to the oil is through the wick. A cover over the oil acts as barrier to prevent the flame from igniting the oil held in the container. The cover can be removable from or integral with the container.
- When the cover and container are integral, the process of filling or refilling an opaque (i.e., non-glass or non-transparent) oil lamp requires at least that the flame be temporarily extinguished and the wick removed. The wick is removed and oil is added into the container through the wick aperture, which often requires the use of a small or specialized funnel which is often misplaced or lost. Where the cover is removable, the flame must still be extinguished before refilling to prevent the oil in the container from igniting.
- A common purpose of oil lamps is to disperse fragrance molecules into the air. However, when the lamp is covered or when the container and cover are integral, the dispersal of fragrance molecules into the air is significantly restricted, if not nonexistent. Some devices propose to disperse the fragrance molecules through the wick. But, the fragrance molecules are usually destroyed or significantly altered when the oil is drawn up through the wick and burned by the flame. The combustion process tends to produce a “fuel” or “burnt” smell instead of the desired odor of the fragrance.
- One approach to an oil lamp that emits a fragrance when ignited is disclosed in U.S. Pat. No. 6,555,069, issued to Ferguson, in which the oil lamp includes a ceramic diffuser. The ceramic diffuser of the '069 patent functions as a secure top, absorbs some of the oil, and releases the absorbed oil into the surrounding air. A drawback is that this type of oil lamp still requires that the flame be extinguished and the top removed before more oil can be added to the container.
- Consequently, there remains a need to maintain the oil securely in the oil lamp, allow a sufficient number of fragrance molecules to be dispersed into the air while the oil lamp is burning, protect the oil from the open flame, and provide a means to easily fill and refill the oil lamp with a reduced risk of underfill, overflow, or leakage. Further, the filling and refilling of the oil lamp should be easy and quick without the need for specialized funnels or tubes to get the oil into the container.
- In one aspect of the invention, a liquid-fueled lamp includes a reservoir to hold liquid fuel, the reservoir having an outer surface and an inner surface; a wick holder supported within the reservoir; a flange coupled with the wick holder, the flange configured with a downward slope directed from the wick holder toward the inner surface of the reservoir; and an opening located between a perimeter of the flange and the inner surface of the reservoir, the opening sized to provide a visual indication of a fuel level of the liquid fuel in the reservoir.
- In another aspect of the invention, a lamp includes a reservoir comprising a wall having an interior surface and an exterior surface, the interior surface forming a reservoir for receiving a liquid fuel, the reservoir open at one end thereof and closed at an opposite end; a wick holder received in the reservoir and coupled to the reservoir, the wick holder forming at least one passage for supportably receiving a wick; a flange extending from the wick holder toward the interior surface, the flange having a perimeter, the perimeter being spaced from the interior surface to form a gap therebetween.
- In the drawings, identical reference numbers identify similar elements or acts. The sizes and relative positions of elements in the drawings are not necessarily drawn to scale. For example, the shapes of various elements and angles are not drawn to scale, and some of these elements are arbitrarily enlarged and positioned to improve drawing legibility. Further, the particular shapes of the elements as drawn, are not intended to convey any information regarding the actual shape of the particular elements, and have been solely selected for ease of recognition in the drawings.

FIG. 1 shows anoil lamp 10 having areservoir 12 and alid 14 according to one illustrated embodiment. Thereservoir 12 is bowl shaped with aninner surface 12 a and anouter surface 12 b. Theinner surface 12 a forms a reservoir to receive fuel, for example a liquid fuel such as oil (with or without fragrance), citronella (lemon odor), citronellol (rose-like odor), or any other like fuel that is slow burning and permissible in a liquid-fueled lamp. Thereservoir 12 has arim 12 c that forms an opening to at an upper end thereof to receive liquid fuel. Aflange 16 and awick holder 18 are positioned within thereservoir 12. Thereservoir 12 can be made out of metal (e.g., stainless steel, aluminum, bronze, copper, etc.), ceramic, or some other flame resistant, opaque material. Thelid 14 and theflange 16 can be made out of the same or an equivalent material. In the illustrated embodiment, thereservoir 12,lid 14, andflange 16 are made out of stainless steel and thewick holder 18 is made from bronze. It is appreciated and understood that thereservoir 12, thelid 14,flange 16, andwick holder 18 can vary in size and shape and the illustrated configuration is exemplary. - The
lid 14 may include adecorative handle 14 a to allow for easy removal and replacement of thelid 14. When theoil lamp 10 is lit, thelid 14 can be used to cover thereservoir 12 andwick holder 18 to substantially starve the flame for oxygen and ultimately extinguish the flame. In addition, leaving thelid 14 on when theoil lamp 10 is not in operation helps keep the oil from evaporating. -
FIG. 2A shows thereservoir 12 of theoil lamp 10 withoil 20 that is filled to anoil level 20 a. In the illustrated embodiment, thereservoir 12 is approximately semi-hemispherical and configured with a substantiallyflat bottom surface 22, which permits theoil lamp 10 to be placed in a stable configuration on a flat surface such as a coffee table, counter top, or shelf, for example. Alternatively, theoil lamp 10 may be supported by a holder such as a wrought iron base, for example. - The
wick holder 18 is supported on theinner surface 12 a of thereservoir 12. Although thewick holder 18 can simply rest on theinner surface 12 a, such would not be as desirable as awick holder 18 that is held stationary in thereservoir 12. In the illustrated embodiment, thewick holder 18 is mechanically coupled with thereservoir 12 to keep thewick holder 18 at least temporarily fixed. There are a variety ways to fixedly or removably mechanical couple thewick holder 18 to thereservoir 12, for example by complementary threads, complementary clipping elements, etc. - The
wick holder 18 includes afirst protuberance 24 that complementarily recesses into aclip 26 extending from thereservoir 12. Thewick holder 18 can be snapped or twisted into place. In an alternate embodiment shown inFIG. 2B , thewick holder 18 and aninner ring 28 are configured with complementary, helical threads that permits thewick holder 18 to selectively be rotationally engaged and disengaged from thereservoir 12. - Referring back to
FIG. 2A , thewick holder 18 further includes asecond protuberance 30. Thesecond protuberance 30 supports theflange 16. Theflange 16 is provided with anopening 16 a sized to fit around the perimeter of thewick holder 18 while not sliding down over thesecond protuberance 30. - In
FIGS. 2A and 2C , theflange 16 has a first height “A” and a second height “B,” both relative to thebottom surface 22 of thereservoir 12. The first height “A” is greater than the second height “B,” which means that theflange 16 is configured to slope downward from its support location on thewick holder 18 toward theinner surface 12 a of thereservoir 12. As shown in the illustrated embodiment, theflange 16 may even have a slight, concave curvature. The downward slope, with or without the curvature, encourages oil that is spilled onto or otherwise contacts theflange 16 to run off the flange and into thereservoir 12. - The
flange 16 further includes anouter perimeter 16 b sized to fit within thereservoir 12. In one embodiment, a cross-sectional area of thereservoir 12, taken parallel to the horizontal, may continually increase as one follows the contour of theinner surface 12 a of thereservoir 12 upward. One skilled in the art will appreciate and understand that cross-sectional area of thereservoir 12 increases exponentially as a function of the diameter (d) of theinner surface 12 a (area=π*d2/4). Theouter perimeter 16 b of theflange 16 is sized to form an opening orgap 32 with respect to theinner surface 12 a of thereservoir 12. Thus, theflange 16 will have a smaller radius andouter perimeter 16 b where theflange 16 is situated at a low elevation in thereservoir 12, while theflange 16 will have a larger radius andouter perimeter 16 b where theflange 16 is situated at a high elevation in thereservoir 12. In any case, theouter perimeter 16 b of theflange 16 is smaller than the perimeter of theinner surface 12 a of thereservoir 12 at a location on theinner surface 12 a opposed to theouter perimeter 16 b. Thegap 32 is large enough to receive theoil 20 during the filling or refilling process without causing theoil 20 to substantially back-up when theoil 20 is poured into thereservoir 12 at reasonable rate. In one embodiment, theoil 20 is poured directly onto theflange 16, but away from thewick holder 18, where theoil 20 then runs down theflange 16, through thegap 32, and into thereservoir 12. -
FIG. 2C illustrates an alternate embodiment in which anupper edge 18 a of thewick holder 18 is flush with aninner portion 16 c of theflange 16. In other words, thewick holder 18 is truncated to be flush with theinner portion 16 c of theflange 16. - One advantage of the
gap 32 is that it allows thelevel 20 a of theoil 20 to be observed during the filling/refilling process without removing thewick 34 or any associated components. It should be understood that thelevel 20 a may not be visible at all times during the refilling process, but as thelevel 20 a increases, thelevel 20 a will become observable through thegap 32 to auser pouring oil 20 into theoil lamp 10. In addition, due to the increasing cross-sectional area of thereservoir 12, as described above, the fill rate (i.e., the rate at which thelevel 20 a rises within the reservoir 12) actually decreases as long as a volumetric input rate of theoil 20 being added remains substantially constant during the filling or refilling process. Hence, a user can refill the reservoir by addingoil 20 at a relatively constant rate with much less concern that theoil 20 will suddenly overflow therim 12 c of thereservoir 12. In short, observing theoil level 20 a through thegap 32 during the filling or refilling process significantly reduces the risk of both overflowing and under filling thereservoir 12. - Another advantage is that the
gap 32 provides a region around theflange 16 where the fragrance molecules of theoil 20 can be directly dispersed into the air. This eliminates the need for special diffusers or other devices. - Yet another advantage is that the
gap 32 permits thereservoir 12 to be filled without removing the wick and/or without special tools. -
FIG. 3 shows thewick holder 18 withwick material 34 placed in thewick holder 18. Thewick holder 18 includes a plurality ofopenings 36 to receive theoil 20 in thereservoir 12. As previously discussed, theoil 20 wets the wickingmaterial 34 through capillary action. Theopenings 36 can be located and spaced around the bottom portion of thewick holder 18 or can be formed in thewick holder 18 slightly above the bottom region. Theopenings 36 can also correspond and align with any openings that are formed in theclips 26 orinner ring 28 used to secure the wick holder with thereservoir 12, as discussed above and illustrated inFIGS. 2A, 2B , and 2C. - Although specific embodiments of and examples for the oil lamp and method of filling the oil lamp are described herein for illustrative purposes, various equivalent modifications can be made without departing from the spirit and scope of the invention, as will be recognized by those skilled in the relevant art. The teachings can apply to any type of oil lamp or other lamp, lantern, or device that uses a combustible liquid for fuel. Additionally, any method described above may include additional steps, omit some steps, and perform some steps in a different order than illustrated and/or otherwise described.

All of the above U.S. patents, patent applications and publications referred to in this specification are incorporated herein by reference. Aspects of the invention can be modified, if necessary, to employ devices, features, and concepts of the various patents, applications and publications to provide yet further embodiments of the invention.
- These and other changes can be made to the invention in light of the above detailed description. In general, in the following claims, the terms used should not be construed to limit the invention to the specific embodiments disclosed in the specification and the claims, but should be construed to include all reusable card configurations and methods that operate in accordance with the claims. Accordingly, the invention is not limited by the disclosure, but instead its scope is to be determined entirely by the following claims.
