Description

Background of the Invention

This invention relates to a cooking utensil kit, and more particularly to a kit of only a few parts which may be combined to serve a wide range of cooking functions.

In the usual home kitchen, a wide variety of kitchen utensils must be stored so that each utensil will be available for the special use for which that utensil is designed. Hence, a large amount of space is wasted in storage of a large number of utensils which are seldom used. For example, one such special purpose utensil is a large pan having a center post therein which is generally used for baking angel food cakes and other cakes having a hole therethrough.

This invention provides a bowl and a post adapted to be centered within the bowl to form a pan.

This invention further provides a cooking utensil kit of only four components which can be combined in different manners to provide a wide range of cooking utensils.

Summary of the Invention

In accordance with principles of this invention various kit parts are provided which can interrelate with one another. These include a large bowl with an internal, centered hemispherical protuberance adapted in size and shape to receive a complementary post member, a conical post member adapted to fit within the bowl base with a complementary indentation in its base for centering the post on the protuberance in the bowl, a serving dish adapted to interfit with the bowl periphery so that each is adapted for use as a cover to the other, and a trivet which can be used separately beneath either the bowl or dish to interfit in centered position within the bowl. The removable center post is adapted to be centered in either of the first components.

Description of a Preferred Embodiment of the Invention

Each of FIGS. 1-4 shows an individual component of the cooking kit. Specifically, FIG. 1 shows a large mixing bowl 22; FIG. 2 shows a center post 28; FIG. 3 shows a serving dish 24; and FIG. 4 shows a trivet 26. Each component is adapted to interfit with each other component of material suitable for use in a microwave home oven. Preferably, the material is a ceramic which is transparent to the microwaves and sufficiently heat resistant for use in a conventional oven. Heat resistant plastic may also be used.

Referring now to FIG. 1, the large bowl 22 comprises a base 30 and closed sides 32. The sides define a rim 34 opposite to the base 30. For reasons to be noted subsequently, the inner surface of sides 32 is irregular, having concave portions 36 around the entire inner surface. The concave portions are bordered by pairs of inwardly protruding ridges 37. Each two ridges 37 define a narrow groove therebetween. Further, for purposes to be discussed, a small central protuberance 38 in the form of a knob is formed in the base 30 at its center. This protuberance 38 is centered in the inner bottom surface of the bowl and is adapted to interengage with a complementary portion on the bottom of the center post. For convenience in handling, handles 40 are also provided.

The post 28 of FIG. 2 comprises a wide base 62 and a narrow, open mouth 64. The post is generally in the shape of a truncated cone with a base outlined by a number of radial extensions 63 defining grooves 65 therebetween. As best shown in FIGS. 5 and 6, a concave indentation 66 is provided at the center of the base. The indentation has a lower diameter corresponding to the largest diameter of the protuberance 38 in the bowl 22 and depth of at least the height of the protuberance 38. By means of the complementary fit between the protuberance 38 on the bottom surface of the bowl and the indentation 66, the center post is adapted to be centered in the bowl to provide a cake pan. Due to the respective spherical concave and convex surfaces of the indentation 66 and the protuberance 38, when the post is moved near the center of the bowl to within the radius of the protuberance, the indentation easily slides down over the protuberance thereby centering the post.

Due to the conical shape of the post, it is very stable when centered in either the bowl or the dish. And because the post has a closed base and open mouth, it may be used separately as a container for syrup or the like. In this regard, it is significant that the indentation and not the protuberance is provided in the base surface of the post since the protuberance would interfere with the stability of the post in its separate use as a container.

In perparing a cake, the batter is first mixed in the bowl with the post removed. Then, the post is held at its top and is plunged into the batter. The closed base of the post easily separates the thin batter and, due to the spherical configuration of the protuberance 38 and the indentation 66, the post is quickly and easily centered in the bowl. The bowl, which was first used for mixing, is then placed with the batter and post into the microwave oven for baking, thereby reducing the number of utensils required.

Once a cake or the like has been baked in the bowl with the center post, the bowl may be inverted in accordance with the usual practice to deposit the cake from the bowl onto a platter. Because the center post sits loosely on the base surface of the bowl it does not interfere with movement of the cake from the bowl but remains centered in the cake. Subsequently, the post is removed axially from the cake. Due to its conical shape, contact between the post and cake is immediately broken as the post is pulled from the cake. This would not be the case with a cylindrical post which would tend to continue to grip the cake.

The serving dish 24, which may be used as a pie pan, comprises a base 42 which also has a protuberance 44 formed therein. Hence, the post is also adapted to be centered in the serving dish for baking a meat loaf or the like. Closed sides 46 surround the base and define a rim 48. Sides 46 are substantially the same size and shape as the rim 34 of the large bowl. That is, because the rim of the bowl in FIG. 1 is circular, the rim 48 is also circular and of about the same diameter.

Lip 50 is formed on rim 48. The inner diameter of lip 50 is slightly larger than the outer diameter of rim 34 on the bowl so that the rims of the bowl and serving dish are adapted for interfitting engagement. Accordingly, the serving dish may be used as such or as the lid to the bowl 22. Alternatively, the bowl may be used as a lid on the serving dish. The serving dish also includes handles 52.

The trivet of FIG. 4 comprises a plate 54 having a rim 58 of the same general shape as rims 34 and 48 on the bowl and serving dish respectively. Plate supporting extensions 56, better shown in FIG. 6, extend from one side of the plate. A floral design on the top surface of the plate provides radial extensions 60. When the trivet is placed inside the large bowl 22 on the base 30 as shown in FIG. 7, the extensions 60 engage complementary concave surface 36 thereby stabilizing the trivet within the bowl. If the trivet is slightly lifted from its position in FIG. 7 and rotated 22.5 degrees relative to the bowl the radial extensions 60 may be rested against the ridges 37. These ridges serve to raise the trivet to the position shown in FIG. 10 to provide a larger space between the trivet and the base 30 of the bowl for drippings and the like.

In the configurations shown in FIGS. 5 and 6, the center post 28 is placed in the large bowl 22 and the serving dish 24, respectively, to provide pans for preparing ring-shaped foods such as angel food cakes.

It is known that the reflecting microwaves in the microwave oven do not provide a uniform wave pattern. There is, in effect, a hole in the wave pattern centrally of the lower portion of the oven. With the dish 24 positioned in the oven on the trivet 26, as shown in FIG. 6, the dish, and thus the food therein, is held substantially above this hole in the wave pattern. With the post in the bowl or dish and the latter positioned centrally in the oven, the food is also held away from the central region of the oven where the hole in the pattern is most likely. The trivet and post thus provide for more uniform cooking. As shown in FIG. 9, the bowl 22, with the dish 24 used as a cover, may also be positioned on the trivet for more uniform microwave cooking. With the pan configuration supported on the trivet 26, the trivet would also protect a heat sensitive surface from the hot serving dish. The trivet may and should be used in this manner for any configuration which does not require the trivet to be placed inside the bowl or dish.

As shown in FIGS. 7 and 8, the trivet 26 may be placed inside either the bowl 22 or dish 24 to support a roast or the like. With the trivet thus positioned the food is held above the hole in the microwave pattern just as before and a space is further provided for drippings. The space may also be used for a liquid when steaming vegetables or the like.

In FIG. 7 the serving dish 24 serves as a cover for the bowl 22 and in FIG. 8 the bowl 22 serves as the cover. Alternatively, each utensil could be used separately without the cover.

Although only six cooking configurations have been shown, it is clear that many more are possible by simply rearranging the four components of the kit.

For storage or shipping the four components of the kit may be compactly stacked as shown in FIG. 11. The trivet is inverted and placed in the bowl with the radial extensions 60 engaging the complementary surfaces 36. The post is then placed centrally on the inverted trivet with radial extensions 63 from the post extending between the plate supporting extensions 56 of the trivet. In this manner, the grooves 65 rest against the supporting extensions 56 to hold the post in a raised position relative to the trivet plate 54. Finally the serving dish 24 is placed as a lid over the bowl. The components are dimensioned so that the protuberance 44 in the serving dish rests in the open mouth 64 of the post 28. With the serving dish placed over the bowl as shown, axial movement of the post and trivet within the bowl is prevented. And the radial extensions 63 from the post and the extensions 60 from the trivet prevent rotational movement of the two components within the bowl.

With the components arranged as shown in FIG. 11 they may be placed in a box with only a minimal amount of packing material for shipping. Alternatively a number of four-component kits may be stacked vertically without packaging for display.

In the home, the kit may be stored in the configuration shown in FIG. 11, thereby substantially reducing the amount of dust collecting on the food-contacting portions of the kit components. Or the bowl may be set upright in the upright serving dish with the trivet and cone placed in the bowl.

While the invention has been particularly shown and described with reference to a preferred embodiment thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims:
