Abstract
Partially insulated dishware and cookware may be provided with selected areas of insulation to provide the user with the ability to grasp the dishware or cookware without the use of an oven mitt or other external device. The selected areas of insulation may also maintain a desired temperature for the dishware or cookware contents, provide sealing capability, and provide resistance to damage by way of shock absorption.
Description
- The above-referenced application claims priority benefits of U.S. provisional patent application serial No. 60/377,931, filed on May 3, 2002.
- The disclosure generally relates to dishware and cookware and, more particularly, relates to disposable dishware and cookware.
- Disposable dishware is widely used. For example, paper plates are ubiquitous at such events as picnics, barbecues and many other social gatherings. Paper cups are used for everything from in-home drinks to dentists offices to fast food restaurants. Milk cartons and restaurant take-out packages are often made of paper material coated with a fluid impermeable layer.
- In other forms of disposable or semi-disposable dishware, relatively thin layers of polypropylene or the like are used to form the dishes. Such dishes can be manufactured at such a low cost that they can be treated by the consumer as disposable, but if desired, washed and reused.
- One difficulty associated with such items, however, is related to temperature exposure. For example, when such items are used within a microwave, it is common for the side of the dish to be heated sufficiently to require a consumer to use an oven mitt or the like for removal. Handles or thick insulating coats can be employed, but such steps result in added cost, potentially removing the items from the popular disposable market. Moreover, the handles and insulating coats often detract from the appearance of the dish or, in the case of a clear dish, prevent viewing of the dish contents.
- Exposure to cold temperatures is equally problematic. In the case of thin polypropylene, the material becomes brittle upon freezing, such that the dish may tend to crack, especially if dropped or otherwise roughly handled. In the case of paperboard, the expansion of the contents of the dish, upon freezing, is often sufficient to rip the paper dish.
- Another area which has not yet been optimized in such dishware, serveware, and cookware is in regard to food warming. After cooking, it is often desirable to maintain the food at an elevated temperature. Traditionally, warming trays with open flame heat sources, or electric heating pads have been employed. Such added equipment, however, adds additional expense and thus prohibits disposable use. Moreover, such heat sources are often in excess of the combustion or melting point of traditional disposable dishware.
- In accordance with one aspect of the disclosure, a dish is disclosed which may comprise of food retaining surface made of cellulosic material and an insulated layer mounted to the food retaining surface.
- In accordance with another aspect of the disclosure, a dish may be provided which may comprise a food retaining surface, an insulated layer mounted to the food retaining surface, and a shock absorbent layer mounted to the food retaining surface.
- These and other aspects of the disclosure will become more apparent upon reading the following detailed description when taken in conjunction with the accompanying drawings.
- FIG. 1 is a schematic representation of a dish constructed in accordance with the teachings of the disclosure;
- FIG. 2 is a schematic representation of a second dish constructed in accordance with the teachings of the disclosure;
- FIG. 3 is a schematic representation of a third dish constructed in accordance with the teachings of the disclosure;
- FIG. 4 is a schematic representation of a fourth dish constructed in accordance with the teachings of the disclosure;
- FIG. 5 is a schematic representation of a fifth dish constructed in accordance with the teachings of the disclosure;
- FIG. 6 is a schematic representation of a sixth dish constructed in accordance with the teachings of the disclosure;
- FIG. 7 is a schematic representation of a seventh dish constructed in accordance with the teachings of the disclosure;
- FIG. 8 is a schematic representation of a eighth dish constructed in accordance with the teachings of the disclosure;
- FIG. 9 is a schematic representation of a ninth dish constructed in accordance with the teachings of the disclosure;
- FIG. 10 is a schematic representation of a tenth dish constructed in accordance with the teachings of the disclosure; and
- FIG. 11 is a schematic representation of an eleventh dish constructed in accordance with the teachings of the disclosure.
- While the disclosure is susceptible to various modifications and alternative constructions, certain illustrative embodiments thereof have been shown in the drawings and will be described below in detail. It should be understood, however, that there is no intention to limit the disclosure to the specific forms disclosed, but on the contrary, the intention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the disclosure.
- Referring now to the drawings, and with specific reference to FIG. 1, a dish constructed in accordance with the teachings of the disclosure is generally referred to by
reference numeral 20. While thedish 20 is depicted in the form of a bowl in FIG. 1, it is to be understood that the dish could be provided in any other form wherein insulation properties are desirable such as, but not limited to, plates, bowls, saucers, servers, casseroles, platters, and the like, many of which are depicted in later figures. - As shown therein, the
bowl 20 may include anexterior wall 22 and a bottom wall 24. Theexterior wall 22 may include arim 26 defining anopen mouth 28 to allow for access to aninterior content space 30. A layer orcoating 32 of insulation such as, but not limited to foam styrene, may be selectively positioned on thebowl 20 to provide for the aforementioned benefits. For example, as shown in FIG. 1, thelayer 32 is provided about alower section 34 of thebowl 20. In so doing, the user is provided with an area to grasp the bowl without risk of burning. Moreover, if theexterior wall 22 is made of a translucent cellulosic material, placement of thelayer 32 about thelower section 34 still leaves anupper section 36 to serve as a area through which to view the contents of thebowl 20. - FIG. 2 depicts a similar embodiment to that of FIG. 1, but illustrates a
cubic dish 38. It is to be understood that myriad other shapes are possible and encompassed within the scope of the present disclosure. Such shapes include, but are not limited to, cross-sectionally hexagonal, pentagonal, triangular, or otherwise polygonal cylinders. - FIG. 3 illustrates a
cup 40 having acylindrical side wall 42 and a closedbase 44. Afirst band 46 of insulation is positioned about acentral portion 44 of thecup 40, while asecond area 48 of insulation is positioned about thebase 44. Thefirst band 46 provides an area allowing a consumer to grasp thecup 40 without subjecting the hand of the user to burning, while thesecond area 48 insulates thecup 40 from heat loss, and as described in further detail herein, provides shock absorption capabilities. - FIG. 4 depicts an alternative embodiment similar to the
cup 40 of FIG. 3. More specifically, FIG. 4 depicts abowl 50 having afirst area 52 of insulation about abase 54 of thebowl 50, and asecond area 56 of insulation about arim 58 of thebowl 50. Thebowl 50 may be made of transulcent material with amiddle section 60 between the first andsecond areas 56 being left unencumbered by the insulation for viewing purposes. - Similarly, FIGS.5-8 depict plates with similar selective application of insulation. For example, FIG. 5 illustrates a
plate 62 having abase 64 with a layer ofinsulation 66 thereon, while FIG. 6 illustrates aplate 68 having anupper surface 70 treated with a layer ofinsulation 72. The embodiment of FIG. 6 could be used as a warming plate, while the embodiment of FIG. 5 would provide a plate having shock absorption and an area for the user to safely grasp. - The
plate 72 of FIG. 7 is the same as that of FIG. 6, but further includes alid 74 which may be entirely insulated to maintain the temperature of the food placed on theplate 72. Finally, aplate 76 of FIG. 8 is similar to that of FIG. 5, but further includes aheat source 78 embedded therein. Theheat source 78 may be any conventional form of heat source including, but not limited to, AC powered or battery powered induction coils or the like. Theplate 76 may include a layer ofinsulation 80 about abase 82 thereof to hinder heat dissipation through thebase 82, and rather conduct the heat generated by thesource 78 through atop surface 84 and ultimately to food held thereon. - Not only can the insulation be used to insulate the contents of the dish from temperature dissipation, but the elastic or resilient nature of such materials also tends to make such dishes more shock absorbing and leak-resistant. For example, in each of the embodiments listed above wherein insulation is provided around a base thereof, the elastic or cushioned nature of the insulation lends itself toward absorbing the force of impact should such a dish be dropped, for example.
- With regard to improved sealing capability or leak resistance, the embodiments of FIGS.9-11 are illustrative. Starting with FIG. 9, it can be seen that a
container 86 is provided that includes acylindrical side wall 88 terminating in arim 90. Alid 92 is provided for closing the container by way of frictional interference between its outer edge and thecontainer rim 90. By providing alayer 94 of resilient insulation about therim 90, a more leak resistant and sealed connection between therim 90 andlid 92 is formed. More specifically, the insulation is sufficiently compressible to allow thelid 92 to connect to therim 90, and sufficiently elastically resilient to move radially outwardly against thelid 92 to thereby form a more leak resistance seal. - The embodiment of FIG. 10 is similar to that of FIG. 9, but rather provides the insulation on the
lid 92 as opposed to therim 90. Finally, the embodiment of FIG. 11 provides the insulation on both therim 90 and thelid 92. Not only do such embodiments provide leak resistance, but also enable the contents of thecontainer 86 to be viewed if made of a clear material. Moreover, the features of any of the foregoing embodiments can be combined with the presently discussed embodiments, and vice-versa, to tailor the dishware, serveware, or cookware to the needs of the particular user. - From the foregoing, one of ordinary skill in the art will readily appreciate that partially insulated dishware, serveware, and cookware can be constructed based on the teachings of the present disclosure. Moreover, one of ordinary skill in the art will understand that variations on the disclosed embodiments can be produced without departing from the scope and protection afforded by the disclosure.
