Definitions
- This invention is in the field of holders for plates and more particularly holders for inexpensive readily bendable disposable paper plates or plate liners which can easily tip or deform in use causing spills of the food, such plate holders being applicable for plates and liners used by both persons and pets.
- Plate holders are known, particularly for pets and infants who are likely to tip or overturn plates from which they are eating. Such plate holders are typically bowl-like articles with an open top to hold a plate and a wide base to provide stability against tipping. It is common to use removable or disposable plate liners that contain the food and sit in a top recess of the plate holder. Plate liners usually have side walls inclined upwardly and outwardly for reasons of functionality, strength, aesthetics and because such is most suitable for efficient manufacture. Plate holders for such plate liners would typically have generally conical walls that define a recess of an inverted truncated cone open and wider at the top and truncated to define a flat surface at the bottom, corresponding to the generally flat bottom of the typical plate liners.
- the outside walls of the plate holder may be vertical or inclined outward so that the base is wider than the top.
- Plate liners are most commonly of molded plastic or paper board or cardboard pressed to define upwardly inclined side walls with a top lip or flange. Such plate liners are supported on or in the plate liner by the top lip of the plate liner overlying and resting on a corresponding surface on the plate holder and/or by the inclined side walls of the plate liner resting against the conical walls of the plate holder.
- U.S. Pat. No. 5,653,362 discloses a disposable pet animal feed container and holder.
- the liner is inserted into a holder until dimples engage the bottom end of skirt on the holder.
- This holder requires the structure of an internal shoulder and skirt to support the liner, and the bottom of the skirt extends into the space within the holder, thus limiting the liner to a size substantially less than the nominal diameter of the holder.
- U.S. Pat. No. 1,922,992 discloses a protector ring used in a restaurant that is placed on the top of a filled plate which allows a second filled plate to rest on the top of the protector while not interfering with the presentation of food on the first plate.
- the top plate will not shift relative to the bottom plate when the two (or more) filled plates are carried by a waiter.
- rigid plates are placed on top of and outside the top of the ring, with no teaching or suggestion to position a paper plate to be rested inside the ring.
- the bottom edge is a stepped-out flange with a vertical wall, while the top edge is a stepped-in flange with a vertical wall.
- U.S. Pat. No. 2,213,837 discloses a child's eating dish and shows several different embodiments all constructed to enable a dish to be placed within a base, made of heat insulating material, with an inner seat. Each of the configurations has a closed bottom and thus cannot be used in an inverted orientation to hold a plate.
- U.S. Pat. No. 2,585,445 discloses a base for supporting a drinking cup. As with U.S. Pat. No. 2,213,837 described above, this base has a closed bottom and thus cannot be used in a inverted orientation to support a cup or other container of another size.
- the present invention seeks to provide an improved plate holder, particularly for persons using disposable paper or plastic plates or plate liners of different sizes at different times.

- the present invention in a preferred embodiment is a reversible plate holder in the form of a circular tube open at both ends, where these ends are of different diameters and each end is tapered as a truncated cone with the diameter of the tube decreasing from the top edge downward and from the bottom edge upward.
- the conical walls of the top truncated conical part flow into and are contiguous with the conical walls of the bottom truncated conical part.
- the bottom edge has diameter less than that of the top edge, and the central area between these opposite ends has a diameter less than the diameters of both the top and bottom edges.
- This plate holder is reversible so that it can hold and support paper plates of different diameters, depending on whether its orientation is upright or upside down. Also, this plate holder may have various heights, as needed. It should be understood that this invention is a holder for plates, plated or container liners and/or other container elements, and reference made herein to one or another of these elements is intended to cover the others.
- the new plate holder be esthetically pleasing with a smooth clean appearance.
- the tube or annulus has walls of generally uniform thickness from the top end to the bottom end. It is further preferable that the inside and outside wall surfaces be smooth and devoid of radially inward extending parts or projections. It is a further object that the outer surface be adaptable to receive graphics for advertising purposes or to present messages for other reasons.
- the new reversible plate holder operable to hold and support selectively first and second plates of first and second diameters respectively, is defined as an annulus or tubular article having axially spaced top and bottom parts with top and bottom edges of diameters D1 and D2 respectively and a neck part of diameter D3 axially between the top and bottom parts where D1>D2 and D2>D3.

- the plate usually has tapered side walls corresponding generally to the tapered walls of the conical surface of the plate holder; however, a plate could be adequately supported so long as at least a portion of the plate's outer surface of its side wall engages at least a portion of the plate support surface.
- the plate could be supported by the rim on the top edge of the annular plate support, but preferably the plate would be supported by both the conical walls and the rim.
- the tapered walls of the opposite conical forms join in a continuous and congruent wall which defines a smooth curved surface on the inside and on the outside of the annulus.
- the opposite conical forms may have generally straight walls which join at the central or neck part of the annulus.
- the preferred embodiment is formed as an annulus or hollow tube having walls of uniform thickness; however, it is possible for the plate holder to be a solid block, either of circular or square or other shape, with a conical recess in each end, one recess having nominal diameter larger than the other.

Description
- 1. Field of the Invention
- This invention is in the field of holders for plates and more particularly holders for inexpensive readily bendable disposable paper plates or plate liners which can easily tip or deform in use causing spills of the food, such plate holders being applicable for plates and liners used by both persons and pets.
- 2. Prior Art
- Plate holders are known, particularly for pets and infants who are likely to tip or overturn plates from which they are eating. Such plate holders are typically bowl-like articles with an open top to hold a plate and a wide base to provide stability against tipping. It is common to use removable or disposable plate liners that contain the food and sit in a top recess of the plate holder. Plate liners usually have side walls inclined upwardly and outwardly for reasons of functionality, strength, aesthetics and because such is most suitable for efficient manufacture. Plate holders for such plate liners would typically have generally conical walls that define a recess of an inverted truncated cone open and wider at the top and truncated to define a flat surface at the bottom, corresponding to the generally flat bottom of the typical plate liners.
- Notwithstanding the conical recess inside walls, the outside walls of the plate holder may be vertical or inclined outward so that the base is wider than the top. Plate liners are most commonly of molded plastic or paper board or cardboard pressed to define upwardly inclined side walls with a top lip or flange. Such plate liners are supported on or in the plate liner by the top lip of the plate liner overlying and resting on a corresponding surface on the plate holder and/or by the inclined side walls of the plate liner resting against the conical walls of the plate holder.
- The use of paper plates for food service both at home for pets and for people, and in restaurants and elsewhere as at picnics and in moving vehicles is massively widespread for a variety of obvious reasons. Such plates are inexpensive and disposable so that washing, drying and storing are unnecessary. They are light weight and thus can be easily transported in standard packaged units and easily carried by persons at dining events whether they be casual meals in a cafeteria or formal events. They can be easily and inexpensively decorated in any color and design simply by printing or other graphic techniques. They can be made in a variety of sizes, styles and qualities including waterproofing.
- U.S. Pat. No. 5,653,362, for example, discloses a disposable pet animal feed container and holder. The liner is inserted into a holder until dimples engage the bottom end of skirt on the holder. This holder requires the structure of an internal shoulder and skirt to support the liner, and the bottom of the skirt extends into the space within the holder, thus limiting the liner to a size substantially less than the nominal diameter of the holder. There is no teaching of reversibility, and furthermore the liner would not work in the reversible orientation due to the extension of the skirt which would be likely to interfere with use in the reversed configuration.
- U.S. Pat. No. 1,922,992 discloses a protector ring used in a restaurant that is placed on the top of a filled plate which allows a second filled plate to rest on the top of the protector while not interfering with the presentation of food on the first plate. Thus, the top plate will not shift relative to the bottom plate when the two (or more) filled plates are carried by a waiter. Here rigid plates are placed on top of and outside the top of the ring, with no teaching or suggestion to position a paper plate to be rested inside the ring. Also, the bottom edge is a stepped-out flange with a vertical wall, while the top edge is a stepped-in flange with a vertical wall.
- U.S. Pat. No. 2,213,837 discloses a child's eating dish and shows several different embodiments all constructed to enable a dish to be placed within a base, made of heat insulating material, with an inner seat. Each of the configurations has a closed bottom and thus cannot be used in an inverted orientation to hold a plate.
- U.S. Pat. No. 2,585,445 discloses a base for supporting a drinking cup. As with U.S. Pat. No. 2,213,837 described above, this base has a closed bottom and thus cannot be used in a inverted orientation to support a cup or other container of another size.
- The present invention seeks to provide an improved plate holder, particularly for persons using disposable paper or plastic plates or plate liners of different sizes at different times. An object of this invention is to provide a plate holder which is a single article designed to accommodate different sized plates and liners by merely inverting the plate holder, and which will retain the characteristics of stability, support, aesthetics and economy of manufacture whether it is upright or upside down. In this application, the term plate holder is intended to mean a holder for plates or plate liners or both.
- The present invention in a preferred embodiment is a reversible plate holder in the form of a circular tube open at both ends, where these ends are of different diameters and each end is tapered as a truncated cone with the diameter of the tube decreasing from the top edge downward and from the bottom edge upward. In a preferred embodiment the conical walls of the top truncated conical part flow into and are contiguous with the conical walls of the bottom truncated conical part. The bottom edge has diameter less than that of the top edge, and the central area between these opposite ends has a diameter less than the diameters of both the top and bottom edges. This plate holder is reversible so that it can hold and support paper plates of different diameters, depending on whether its orientation is upright or upside down. Also, this plate holder may have various heights, as needed. It should be understood that this invention is a holder for plates, plated or container liners and/or other container elements, and reference made herein to one or another of these elements is intended to cover the others.
- It is an object of the present invention to provide a plate holder that will not only hold, support and stabilize a paper plate, but will be reversible by a simple inversion, so that it can hold plates of different sizes. Whether for pets, at home or picnics outside or for restaurant establishments, it is believed quite practical and useful to be able to provide plate holders selectively for large and small portions. Also, the new plate holder will help retain the hot or cold temperature of the food in the plate or liner being supported. The plate holders must, of course, be quite stable from tipping or collapsing. Also, these new plate holders need to be most simple in construction to achieve minimum cost of manufacture. Typical manufacturing is by high speed injection molding if plastic, and by other molding or pressing technologies if the plate holder is made of other material.
- Last, but not least, it is an object that the new plate holder be esthetically pleasing with a smooth clean appearance. In one such reversible plate holder, the tube or annulus has walls of generally uniform thickness from the top end to the bottom end. It is further preferable that the inside and outside wall surfaces be smooth and devoid of radially inward extending parts or projections. It is a further object that the outer surface be adaptable to receive graphics for advertising purposes or to present messages for other reasons.
- In one preferred embodiment the new reversible plate holder, operable to hold and support selectively first and second plates of first and second diameters respectively, is defined as an annulus or tubular article having axially spaced top and bottom parts with top and bottom edges of diameters D1 and D2 respectively and a neck part of diameter D3 axially between the top and bottom parts where D1>D2 and D2>D3. In this annulus the top part has inner wall surfaces that define a truncated top cone, and the bottom part has inner wall surfaces that define a truncated bottom cone generally coaxial with the top cone, whereby the annulus in upright position has the top cone at the top for supporting the first plate, and the annulus in inverted position has the bottom cone at the top for supporting the second plate, where the rims of the plates overlie the top and bottom edges respectively and the side walls of the plates overlie the conical wall surfaces respectively.
- Accordingly, it is an object to provide a plate holder that can be used in an upright orientation for a plate of a first diameter, or inverted to be used for a plate of a second different diameter.
- In each orientation the plate holder has a conical shaped inner wall to receive, support and hold the tapered outer wall of the sides or flange of a paper plate, with the outer rim of the plate overlying the terminal top or bottom edge of the annulus for further support. The plate usually has tapered side walls corresponding generally to the tapered walls of the conical surface of the plate holder; however, a plate could be adequately supported so long as at least a portion of the plate's outer surface of its side wall engages at least a portion of the plate support surface. Alternatively, the plate could be supported by the rim on the top edge of the annular plate support, but preferably the plate would be supported by both the conical walls and the rim.
- In another preferred embodiment the tapered walls of the opposite conical forms join in a continuous and congruent wall which defines a smooth curved surface on the inside and on the outside of the annulus. Alternatively, the opposite conical forms may have generally straight walls which join at the central or neck part of the annulus.
- As described above, the preferred embodiment is formed as an annulus or hollow tube having walls of uniform thickness; however, it is possible for the plate holder to be a solid block, either of circular or square or other shape, with a conical recess in each end, one recess having nominal diameter larger than the other. Such block could be inverted to allow selection of the opposite end to support a plate of smaller diameter. The new plate holder may be made preferably of silicone rubber or plastic, but also of paper or cardboard material or even ceramic, wood or metal.
- This invention of a plate holder is also useful as a holder for frozen foods or microwavable dishes to help stabilize them whether they are being used during eating, storage, freezing, heating or cooking.
- Other objects, features and characteristics of the present invention, as well as the methods of operation and function of the related elements of the structure, and the combination of the parts and economies of manufacture, will become more apparent upon consideration of the following detailed description and appended claims with reference to the accompanying drawings, all of which form a part of this specification.

These angles may vary along with the heights of the top and bottom parts respectively; however, some standard size plates for which this plate holder is intended, have nominal diameters six, seven and ten inches. The new reversible plate holder can accommodate plates of many different heights, because the conical receiving area will simply engage the portion of a plate's outside circumferential wall surface which corresponds in diameter and height to inside conical wall surfaces of the plate holder. Some plate walls are relatively straight, while others are generally convex. Either can be well supported by the plate holders' inside wall surfaces.

Thisplate holder 70 is reversible by inverting the base similarly as with the plate holder ofFIGS. 1-4 . The solid walls add bulk and weight which enhances stability regardless of which end is positioned downward. -
FIGS. 9 and 10 are representative of a solid reversible plate holder having opposing co-axial conical recesses as seen inFIG. 4 or 5, and having any outer shape which may be for example, round, oval, rectangular, square or octagonal that are concentric with the conical recesses, or may be non-concentric therewith. Also, the conical top and bottom recesses are not required to be co-axial. - In the various reversible plate holders illustrated, if the top and bottom edges are thinner than the width of the plate rim, the rim will readily fit over and engage the edge, tending to center the plate on the edge. Where the edge is wider than the plate rim, the edge will overlie and be supported, but not engage the rim in a manner that tends to center the plate in the recess.
-
FIGS. 11 and 12 represent afurther embodiment 82 of a reversible plate holder similar to that ofFIGS. 9 and 10 except that theouter surface 84 is square. InFIGS. 11 and 12 the side walls are square or rectangular, and the upper and lower truncatedconical areas areas FIGS. 9 and 10 . Also, the plate holders ofFIGS. 9-12 could be hollow instead of solid. - It should be appreciated that the objects of the invention have been fully and effectively accomplished by the present invention and it will be realized however that the forgoing preferred embodiments have been shown and described for the purpose of illustrating the structural and functional principles of the present invention and are subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit of the following claims.
