DETAILED DESCRIPTION OF SOME EXAMPLE EMBODIMENTS Some example embodiments of the present invention will be explained with reference to the accompanying drawings. In general, such embodiments can be used in a variety of applications, and it should be noted that the following examples are not intended to limit the scope of the invention in any way. For example, embodiments of the invention can be used in applications such as injury treatment and rehabilitation, physical therapy, massage, diagnostic and other medical procedures, cosmetology, and nutrition. The materials used in such applications can include any materials suitable for topical application and/or transdermal delivery, examples of which include drugs, medicines, nutrients, vitamins, minerals, and beauty products. Other example materials include edible materials, and materials with industrial applications such as grease and other lubricants.
In many instances, such materials are in the form of, or carried by, a gel, lotion, balm, salve, cream or ointment that can be applied to the skin and/or other parts of a subject. When such materials are heated using embodiments of the invention, these materials may be applied to a subject and/or absorbed relatively more quickly by the subject than would otherwise be the case. Examples of such subjects include humans and animals, although embodiments of the invention can have uses that do not involve materials that can be applied to a human or animal.
Although various disclosed embodiments are contemplated for use with materials that could be applied to, or otherwise used by, humans and/or animals, it should be understood that the scope of the invention is not so limited. In fact, at least some of the disclosed embodiments can be used in connection with any material(s) that require, for example, one or more of heating, partial melting, or complete melting, for use. Thus, at least some embodiments of the invention could be used in applications as varied as food preparation and cooking applications, industrial applications, veterinary applications, and laboratory applications, to name a few examples. Still other applications will be apparent to the person of ordinary skill in the art having the benefit of this disclosure.
A. Aspects of Some Example Embodiments With attention now to FIGS. 1-3, details are provided concerning a heating system, example embodiments of which are indicated at 100 in the Figures. In general, the heating system 100 may include a container 200 that includes a container body 202 and a removable lid 204 attached to the container body. The removable lid 204 can attached to the container body 202 in any suitable way. For example, the removable lid 204 and container body 202 can each have complementary threads, or the removable lid 204 can remain in place on the container body 202 with a slip, friction or snap fit. In other embodiments, the removable lid 204 and/or container body 202 can be magnetic, or include one or more magnets, so that a magnetic force tends to retain the removable lid 204 on the container body 202.
In some instances, the container 200 may be a single-use disposable container that is pre-filled with one or more materials. In this example, the container 200 thus constitutes a consumable item that can be discarded and replaced with another container. In yet other embodiments, the container 200 may be made of recyclable materials. In still other embodiments, the container 200 may be made for repeated use. As well, the container 200 is made of biodegradable materials in some embodiments.
In terms of its construction, the container 200, including one or both of the container body 202 and a removable lid 204, can be made of any suitable materials, including any one or more of rubber, plastic, metal, glass, composites, ceramic, paper, or cardboard. Where permeable materials such as paper or cardboard are used in the construction of the container 200, including one or both of the container body 202 and a removable lid 204, those materials may be coated with a moisture-proof or moisture-resistant coating. The container 200, including one or both of the container body 202 and a removable lid 204, may be rigid, or semi-rigid. In some embodiments, part or all of the container 200 can include thermal insulation to aid in heat retention.
As indicated in FIGS. 1-3, some example containers 200 may have a generally cylindrical shape, although the scope of the invention is not limited to any particular shape. For example, other container shapes include square, rectangular, round, pyramidal, or conical. Likewise, dimensions such as the height, diameter and width of the container 200 can be selected as desired. While not specifically illustrated, containers in accordance with embodiments of the invention may be releasably lockable to the base so as to prevent removal of the container when the heating element, discussed below, is operating. Such locks can be configured to release the container once the heating element temperature has dropped to a defined temperature.
With continued reference to FIGS. 1-3, the example heating system 100 further includes a heating assembly 300 that includes a heating element (see FIG. 4) arranged for substantial contact with the container 200. In the example of FIGS. 1-3, the container 200 rests on top of the heating assembly 300. However, the positioning of these elements can be reversed such that the heating assembly 300 rests on top of the container 200. In this latter configuration, the heating assembly 300 can also serve as a removable lid 204 for the container 200. As further indicated in FIGS. 1-3, the container 200 and heating assembly 300 may be configured such that they fit closely together with each other to define a substantially continuous outer surface 102 of the heating system 100.
With particular reference to FIG. 2, at least some embodiments of the heating assembly 300 and/or the container 200 can include one or more heat sensitive elements 302 in thermal communication with the heating assembly 300 and/or container 200. In operation, the heat sensitive element 302 changes its color in relation to a relative temperature of one or more of the container 200, heating assembly 300, or material disposed in the container 200. For example, the heat sensitive element 302 may turn a first color when it is at a first temperature, or in a first range of temperatures, and the heat sensitive element 302 may turn a second color when it is at a second temperature, or in a second range of temperatures. The heat sensitive element 302 thus enables a user to verify whether or not the materials in the container 200 are at a desired temperature. It should be noted that any other device(s) having functionality comparable to that of the heat sensitive element 302 may alternatively be employed. Moreover, the heat sensitive element(s) 302 can be positioned in any location(s) on or in the heating system 100 that enables the aforementioned functionality.
B. Aspects of an Example Heating Assembly and Components Turning now to FIG. 4, further details are provided concerning an example heating assembly 300. As indicated there, the heating assembly 300 may include a base 304 that supports a heating element 306. The base 304 and heating element 306 may be integral with each other, or can be separate parts that are removably, or permanently, attached to each other. Where the base 304 and heating element 306 are removably attached to each other, such attachment can be effected, for example, by a threading engagement between the two parts. The base 304 may, alternatively, define a recess in which the heating element 306 can be removably placed. In this configuration, the weight of the heating element 306 may serve to retain it in the base 304.
The base 304 and/or heating element 306 can be made of, or include, any suitable materials, examples of which include metal, glass, or ceramic. As well, one or both of the base 304 and heating element 306 can be coated with one or more of the aforementioned materials, and/or with rubber, plastic, or paint for example. The base 304 and/or heating element 306 may include thermal insulation on their respective exterior portions. In some embodiments, the base 304 is weighted to provide resistance to being tipped or knocked over.
The heating element 306 can be electrically powered, such as by A/C or D/C current and, in one example embodiment, takes the form of a resistance heater that generates heat when power is applied to it. Other suitable heater types can additionally, or alternatively, be employed. For example, the heating element can be an induction-based heating element that remains cool to the touch and only generates heat when in contact with a metallic object, such as some embodiments of the container. In some instances, the heating element 306 comprises or includes a material with relatively high heat retention qualities, such as ceramic for example. Such configurations can be heated quickly, such as in a microwave oven for example, and then placed in thermal communication with the container 200, where the heating element 306 can transfer heat to the container for a relatively long period of time. These configurations of the heating element 306 may, or may not, also include an electrically powered heater.
With continued attention to FIG. 4, and directing attention now as well to FIGS. 5 and 6, further details are provided concerning aspects of example embodiments of the heating element 306. As indicated in those Figures, the heating element 306 and container 200 are generally configured so that the container 200 encloses a portion, which may be a substantial portion, of the heating element 306. As a result of this configuration and arrangement of the heating element 306 and container 200, and as best indicated in FIG. 6, the heating element 306 is operable to heat material in the container 200 from a location within the outer walls 206 of the container 200.
As further indicated in FIGS. 4-6, the heating element 306 may have a generally conical shape, although that is not required. Other shapes for the heating element 306 include cylindrical and pyramidal. As indicated in FIGS. 4-6, the outer surface of the heating element 306 may have a generally concave shape while the corresponding portion of the recess 208 that contacts the heating element 306 may be generally convex. However, the scope of the invention is not limited to any particular shape, or shapes, for the heating element 306 and recess 208. In some instances at least, the shape of the heating element 306 may be selected to achieve a heat transfer area of a desired size. Moreover, the scope of the invention is not limited to any particular dimensions or aspect ratios (such as, e.g., width:height) for a heating element.
As well, although the example heating element 306 is generally symmetric about its vertical axis A-A (FIG. 6), other embodiments of the example heating element 306 are asymmetric about their vertical axis. Further, although the example heating element 306 can be generally vertical in its orientation, that is not required, and one or more other embodiments of the heating element may have a non-vertical orientation. In all of the aforementioned example embodiments, the container 200 is configured to include a shape and orientation that are complementary to the shape and orientation of the heating element.
More generally, any configuration of the heating element 306 which enables at least a portion, and a substantial portion in some embodiments, of the heating element 306 to be enclosed by the container 200 can be employed. One example of such a configuration is the male (heating element 306)-female (recess 208) arrangement indicated in FIGS. 4-6, although the scope of the invention is not limited to this particular configuration.
While the Figures indicate a generally smooth outer surface 306a of the heating element 306, that configuration is not required. Thus, in other embodiments, the outer surface of the heating element can be textured and/or include other surface treatments.
As best indicated in FIG. 6, embodiments of the container 200 are generally configured to define a recess 208 whose shape and size are complementary with the shape and size of the corresponding heating element 306. This complementary relationship may, for example, facilitate relatively better heat transfer from the heating element 306 to the container 200, and may also provide stability to the heating system 100 by virtue of a relatively close fit between the heating element 306 and the recess 208.
In some embodiments, the heating element 306 can include one or more protruding elements, such as a substantially vertical fin (not shown) for example that is received in a corresponding groove of the recess 208. Such a protruding element can serve to prevent rotation of the container 200 relative to the heating element 306, and can also help to ensure that the container 200 is oriented in a particular way relative to the heating element 306, should such orientation be useful. One or more protruding elements can also provide for enhanced heat transfer from the heating element 306, inasmuch as the surface area of the heating element 306 is increased, and conductive heat transfer is a function of surface area.
Although a single centrally located heating element 306 is indicated in FIG. 6, the scope of the invention is not so limited. For example, some embodiments can include multiple heating elements, at least one of which may be located off-center relative to a vertical axis defined by the container 200. Yet other embodiments can include a single off-center heating element. The corresponding containers in these alternative embodiments are configured with a shape, size and orientation that complementary with the heating element(s).
With continued reference to FIG. 6, the container 200 includes, as noted above, outer walls 206 that cooperate with the recess 208 to define an interior 210 of the container 200. Any material(s) desired to be heated by the heating element(s) 306 can be placed in the interior 210 of the container 200. Examples of such materials are disclosed elsewhere herein. One useful aspect of the particular shape of the interior 210 of FIG. 6 is that when a user inserts one or more fingers into the interior 210, the outer walls 206 and recess 208 may cooperate to direct materials in the interior 210 upward where they are more readily accessed by the user.
With reference now to FIG. 6a, details are provided concerning a modified container 200a having a container body 202a configured to receive a lid 204a. The container body 202a includes an annular shoulder 203a upon which the lower edge 205a of the lid 204a can rest. This lid and shoulder configuration can be employed in any of the disclosed embodiments, but is not required to be.
C. Aspects of Additional Example Embodiments Directing attention now to FIGS. 7a to 11b, details are provided concerning various alternative embodiments of a heating system. It should be noted that still other example embodiments are discussed herein in connection with FIGS. 13a-38c, discussed below.
With attention first to FIGS. 7a and 7b, a heating system 400 is disclosed. The heating system 400 may be similar to, or the same as, any of the other disclosed embodiments, except for the respective shapes of the heating element 402, corresponding recess 404, base 406, container 408, and lid 410. With particular reference to the container 408, the embodiment in FIGS. 7a and 7b has a tapered shape that has a relatively smaller outside diameter at the base and a relatively larger outside diameter at the top. The lid 410 can be similarly tapered.
With attention now to FIGS. 8a and 8b, a heating system 500 is disclosed. The heating system 500 may be similar to, or the same as, any of the other disclosed embodiments, except for the substantially cylindrical shape of the heating element 502, corresponding recess 504, base 506, container 508 and lid 510.
With attention now to FIGS. 9a and 9b, a heating system 600 is disclosed. The heating system 600 may be similar to, or the same as, any of the other disclosed embodiments, except for the respective shapes of the heating element 602, corresponding recess 604, base 606, and container 608. The lid 610 may have a shape similar to the shape of other lids disclosed herein, such as lid 510 for example. Similar to other embodiments disclosed herein, the heating system 600 can include a heating element 602 that is electrically powered, and a power cord 612 can be provided for this purpose.
Turning now to FIGS. 10a and 10b, a further embodiment of a heating system 700 is disclosed. Similar to other embodiments disclosed herein, the heating system 700 includes a heating element 702, recess 704, base 706, and container 708. However, the heating system 700 differs somewhat from those embodiments in that the container 708 is fitted with a pump system 710. As indicated in FIGS. 10a and 10b, the pump system 710 can include a delivery tube 712 that may extend a substantial distance into the container 708, possibly near, or at the bottom of the interior of the container 708. The delivery tube 712 can be rubber, plastic and/or any other suitable material(s). A pump head 714, which can be spring loaded or otherwise biased, is connected to the delivery tube 712 by way of a pump head inlet 716. As the pump head 714 is depressed, pressure is exerted on the interior 708a of the container 708, causing the material in the container 708 to move upward in the delivery tube 712, and out of the pump head by way of the pump head outlet 714a.
