CROSS REFERENCE TO A RELATED PATENT APPLICATION [0001] This application is a continuation-in-part application of my co-pending U.S. application Ser. No. 10/849,262 filed on May 20, 2004 and entitled Pleated Disposable Paper Cup BACKGROUND [0002] 1. Technical Field [0003] The present application relates to disposable cups or like containers or receptacles, methods of manufacture thereof, and the use of such cups. [0004] 2. Background Information [0005] Disposable cups and like containers are in use at most of the common fast food outlets and are accordingly in wide-spread use. The main concern with such cups is the safe handling of the cup when it contains a hot liquid such as coffee. [0006] Thus, one manner to protect a user of a cup containing a hot liquid comprises double-cupping which is widely used in the industry to solve the problem of cups being too hot to handle safely. Further, supplementary insulating sleeves such as shown in U.S. Pat. No. 5,205,473 represent another method that has been employed to make paper cups safer to use when filled with hot contents. Multi-layered paper cups have also been designed to provide insulation between hot liquid contents and a user's hand, such as, in U.S. Pat. No. 3,908,523 to Shikaya, 1995; No. 5,205,473 to Coffin, Sr., 1993; No. 5,547,124 to Mueller, 1996; No. 5,769,311 to Norika et al., 1998; No. 5,775,577 to Titus, 1998; and No. 6,378,766 to Sadlier, 2002. [0007] The coffee industry is further organized in such a way that larger quantities of coffee are brewed, say in espresso machines or brewing vessels, and portions of hot coffee are dispensed for a buyer. Thus there arises the problem that the coffee may be held in a state of a heated condition that possibly may render the dispensed portion of coffee in a somewhat stale condition when dispensed for a buyer. OBJECTS [0008] It is a primary object of the present application to provide a disposable paper cup which is of a more effective and efficient configuration in terms of insulating a user from the hot liquid than those mentioned herein above, and to alleviate the problems associated with the need to provide insulation between cups or containers which contain hot or cold contents and a hand of a user. [0009] It is still another object of the present application to provide a disposable paper or card-stock material cup which is aesthetically attractive, distinctive, and simple in construction, and in which insulation qualities have been incorporated into the structure and design of the cup to protect the hand of a user from the hot or cold content of the cup, without the need for supplementary insulating sleeves or double-cupping. [0010] It is also an object to provide an arrangement enabling a user to prepare a personal cup of a freshly prepared and non-aged coffee or similar drink. SUMMARY [0011] The primary feature of the present application provides a substantially improved insulation quality by a main, cylindrical body component with a wall structure that has a zigzag pleated shape to allow airflow between the full body of the cup and a hand of a user. Also, contact between a hand of a user and the main body of the cup is minimized to the outer points of the pleats or ridges of the body, thereby substantially reducing the surface area of the cup which may be heated or cooled by the content of the cup while also contacting a hand of a user. Accordingly, safety and ease of use are greatly improved. [0012] The object may also be accomplished by a container for holding hot liquids, cold liquids, food items, and the like, said container comprising: a wall structure comprising a plurality of ridges and valleys being interior ridges and valleys in the finished condition of said container and said interior ridges and valleys being configured to be in direct contact with a content of said container; and said wall structure comprising a plurality of ridges and valleys being exterior ridges and valleys in the finished condition of said container, said exterior valleys being configured to permit flow of air to cool the exterior of said container and said exterior ridges being configured to minimize exposure to heat or to cold to a hand of a user. [0013] In one aspect at least one object may further be accomplished by a disposable container for holding hot liquids, cold liquids, food items, and the like, said container comprising: a structure having a length dimension and a width dimension greater than said width dimension in the unassembled condition of said container and being configured to form a cylindrical shaped body with a top and a bottom remote from said top by said width dimension; said structure comprising a plurality of ridges and valleys being interior ridges and valleys in the assembled condition of said container and said interior ridges and valleys being configured to be in direct contact with a content of said container; said structure comprising a plurality of ridges and valleys being exterior ridges and valleys in the assembled condition of said container, said exterior valleys being configured to permit flow of air to cool the exterior of said container and said exterior ridges being configured to minimize exposure to heat or to cold to a hand of a user; a bottom structure being configured and disposed to close said bottom of said container; and an arrangement being configured and disposed to form a mouth portion at said top of said container. [0014] There is also provided a disposable container wherein said stock structure comprises a card stock, a paper stock or a paper-like material as known in the art with at least one moisture repellant side. Such material may, in one embodiment of my application, be a biodegradable material. In one embodiment, the cup is made of a paperboard having a coating comprising a thin layer of polyethylene. In one embodiment, the paperboard is coated on both sides with polyethylene. It will be appreciated that the present application is fully applicable to a cup such as is known as a cup having the marking: NO. 2346P37636 DIXIE.RTM.

FORT JAMES CORPORATION, MADE IN U.S.A. E; or as a cup having the marking: DART A00 o77 12J12. Such cups are widely used at least in Canada by various fast food outlets. Such cups and their material of construction are hereby incorporate by reference as if set forth in their entirety herein. [0015] There is also provided a disposable container according to one embodiment wherein said ridges and valleys comprise at least one of isosceles ridges and valleys and rounded ridges and valleys. [0016] There is also provided a disposable container wherein said ridges and valleys have a height dimension of approximately one quarter of an inch. [0017] There is also provided a method of producing a container with a zigzag shaped, pleated body or sidewall component of a paper or card stock material, or paper-like material, which method comprises placing the blank cut to predetermined dimensions across the cavity of a die set, and then lowering the top part of the die set on top of the card stock or blank so that the weight of the top part of the die set pushes the card stock into the shape of said cavity to form a predetermined piece of pleated cardstock. The piece of card stock thereby shaped and produced will herein also be called the cylindrical sidewall component of the container.
