Abstract

A thermally insulated cup or container (30) includes a smooth outer shell (12S), a smooth inner shell (13S), a corrugated layer (11L) sandwiched therebetween, and a bottom closure (14). The inner shell, corrugated layer, and outer shell are formed by simply winding a continuous elongated paper sheet (10) in a three-layered spiral, then sealing them together. The corrugated layer forms many air pockets between the shells to thermally insulate the contents of the cup, and also provide structural strength. The paper construction of the cup makes it biodegradable and recyclable, and the simple construction method of the cup makes it easy and inexpensive to manufacture.

Description

BACKGROUND OF THE INVENTION
1. Field of Invention
This invention relates generally to disposable cups, specifically to an insulated paper cup.
2. Prior Art
There are three main types of disposable cups: paper, expanded resin, and polystyrene. Polystyrene cups are aesthetically pleasing, but they can only be used for holding cold drinks, and are not biodegradable or recyclable. Cups of expanded synthetic resin material, sold under the trademark Styrofoam, are excellent thermal insulators, so that they can maintain the temperature of a drink, whether hot or cold, for long periods of time. They are comfortable to handle because their exteriors stay close to ambient temperature, regardless of the temperature of the drink. However, they are environmentally unfriendly, because they are not biodegradable or recyclable. As a result, they are being banned from many municipalities.
Standard single-layer paper cups are recyclable, and therefore more environmentally sound. However, they are poor thermal insulators, so that a beverage in a paper cup quickly looses its cold or heat. They are also uncomfortable to handle, because a hot drink can burn a hand, whereas a cold drink will cause condensation on their outsides, making them slippery and difficult to hold. Their single-layer construction makes them fragile, so that large cups filled with liquid easily crumble after prolonged handling.
Multi-layered paper cups have been designed for providing thermal insulation and increased strength. U.S. Pat. Nos. 2,661,889 to Phinney (1948), 4,993,580 to Smith (1991), 5,092,485 to Lee (1992), and 5,205,473 to Coffin (1993) show three-layered cups with smooth outer and inner shells, and a corrugated middle layer. The corrugated layer provides air pockets for thermal insulation and added strength to withstand prolonged handling.
Although strong and thermally efficient, these cups are all expensive to manufacture, because their three layers are formed separately and then assembled together. This requires at least three glue joints for the forming the layers into tapered cylinders, two glue joints for assembling the layers together, and a glue joint for attaching the bottom. Some cups require even more glue joints. The liberal use of glue renders the cups difficult or impossible to recycle. The layers are usually formed from arc-shaped sheets cut separately from blanks, so that they do not make the most efficient use of paper. Furthermore, the many manufacturing steps required make them too expensive to market. As a result, these cups have never achieved commercial success.
OBJECTS AND ADVANTAGES
Accordingly, several objects and advantages of the invention are to provide a cup which is thermally insulated for comfortable handling and for maintaining the temperature of its contents, which is sturdy enough for withstanding prolonged handling, which is biodegradable and recyclable, and which is easy and inexpensive to manufacture.
Further objects and advantages will become apparent from a study of the following description and the accompanying drawings.

SUMMARY OF THE INVENTION
In accordance with the present invention, a thermally insulated cup is formed from one continuous sheet of paper having two smooth portions and a corrugated portion therebetween. The sheet is wound into a three-layered spiral, then the ends of each smooth portion are glued together for forming cylindrical inner and outer shells that sandwich the corrugated portion therebetween. A bottom closure is attached to the inner shell. The resulting three-layered cup is strong, and offers good thermal insulation for comfortable handling and maintaining the temperature of its contents.
DESCRIPTION--FIGS. 1A TO 1C--PAPER SHEETS
In accordance with a first embodiment of the invention shown in the exploded side view in FIG. 1A, a cup or container (FIG. 3) begins as a continuous, homogeneous sheet 10, which is die cut from blank paper stock (not shown). Sheet 10 includes a rectangular, corrugated portion 11, and two wider, arc-shaped, smooth portions 12 and 13 extending from either side of corrugated portion 11. Smooth portions 12 and 13 have proximal ends 12P and 13P, respectively, free ends 12F and 13F, top edges 12T and 13T, and bottoms edges 12B and 13B. Cutting corrugated portion 11 as a straight piece allows multiple sheets 10 to be cut very closely from the same blank, which makes the most efficient use of the paper stock. A round, bottom closure 14 is cut separately. The corrugations in portion 11 are clearly shown in the edge-on view in FIG. 1B. They are formed by methods well known in the art.
In accordance with a second embodiment of the invention shown in the exploded side view in FIG. 1C, a continuous sheet 20 can be formed by gluing together the appropriate edges of a corrugated piece 21 and separate smooth pieces 22 and 23. Bottom closure 24 is also cut separately. Corrugated piece 21 is slightly longer than corrugated portion 11 shown in FIG. 1A, so that its ends slightly overlap smooth pieces 22 and 23 for gluing. Cutting the three pieces separately may allow them to be cut even more efficiently from the paper stock.
DESCRIPTION--FIGS. 2A AND 2B--MANUFACTURING PROCESS
The cup (FIG. 3) is formed by winding sheet 10 into a spiral, as shown in FIG. 2A. Free end 13F is glued or otherwise joined to proximal end 13 P to form a tapered cylindrical inner shell 13S. Then free end 12F is joined to proximal end 12P to form a tapered cylindrical outer shell 12S, as shown in FIG. 2B. Corrugated portion 11 is thus sandwiched between the shells to form a corrugated layer 11L. Bottom closure 14 is attached within inner shell 13S, as will be explained in conjunction with FIG. 3.
Smooth portion 13 is slightly longer than the circumference of inner shell 13S, so that the excess at its ends overlap for gluing. Although corrugated portion 11 (FIG. 1A) is rectangular, it can be wrapped around tapered inner shell 13S by spreading its corrugations wider at its top. Smooth portion 12 is longer than smooth portion 13, so that after they are formed into cylinders, outer shell 12S is larger in diameter than inner shell 13 S for accommodating the thickness of corrugated layer 11L. End portion 12 is also longer than the circumference of outer shell 12, so that the excess at its ends overlap for gluing. Although sheet 10 is used in this example, sheet 20 (FIG. 1C) can also be used.
Thus constructed, corrugated layer 11L forms many thermally insulating air pockets 15 between itself and the shells. After the cup is assembled, it is coated with a suitable waterproofing material 16, such as plastic or wax. The inside surface of middle layer 11L is optionally coated with a reflective material 17. This will reflect radiant heat back to its source, whether from the cup's contents or from the air outside the cup, so that thermal efficiency is further improved. Because the three layers of the cup are constructed by simply winding sheet 10 into a spiral, it is very easy and economical to manufacture.
DESCRIPTION--FIGS. 3--SIDE SECTIONAL VIEW
As shown in the side sectional view in FIG. 3, cup 30 includes three layers formed by outer shell 12S, corrugated layer 11L, and inner shell 13S. Top edges 12T and 13T are crimped together and rolled outwardly to form a rim. Bottom edges 12B and 13B are folded inwardly, and glued to the inside of a rim 14R on bottom closure 14 for a watertight seal. Because corrugated portion 11 (FIG. 1A) is narrower than smooth portions 12 and 13 (FIG. 1A), the top and bottom edges of corrugated layer 11L stay clear of the crimped top and bottom of cup 30.
SUMMARY, RAMIFICATIONS AND SCOPE
Accordingly the reader will see that I have provided a thermally insulated cup or container which will maintain the temperature of its contents much longer than non-insulated cups. When it is holding a hot beverage, it will maintain its outer shell at close to ambient temperature, so that the cup will be comfortable to handle. When it is holding a cold beverage, it will prevent condensation from forming on its outer shell, so that it will not become slippery. The corrugated, three-layered construction makes it strong enough to withstand prolonged handling. Its paper construction and its minimal use of glue makes it biodegradable and recyclable. Its design make very efficient use of paper stock, so that it consumes a minimal amount of natural resources. Because its three layers are constructed by simply winding a single piece of paper around in a spiral, it can be easily and inexpensively manufactured.
Although the above descriptions are specific, they should not be considered as limitations on the scope of the invention, but only as examples of the preferred embodiment. Many other ramifications and variations are possible within the teachings of the invention. For example, instead of paper, other suitable materials, such as plastic, if available, can be used. The reflective coating can be eliminated. The three separate elongated pieces shown in FIG. 1C can be crimped instead of glued together. The construction method of forming a three-layered cup from a continuous sheet can be used for creating types of insulated containers, such as milk cartons, ice cream cartons, etc. The corrugations of the middle layer, instead of vertical ribs, can take other forms, such as an array of dimples, horizontal ribs, etc. Therefore the reader is requested to determine the scope of the invention by the appended claims and their legal equivalents, and not by the examples given.
