BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to cookware apparatus, and more particularly pertains to a new and improved balanced cookware construction wherein the same includes a forwardly positioned counter-balance weight to offset the moment of force created by a conventionally associated handle. 
     2. Description of the Prior Art 
     The use of cookware and the like is well known in the prior art and as may be appreciated, these devices have normally been of conventional construction with a main open container formed within a fixed handle thereto. Conventional cookware is formed of typical metal forming means, such as stamping, casting, and/or spinning. Resultantly, the main cooking container portion is balanced about a central center of gravity positioned somewhat medially of the bottom cooking surface of the pan with an attendant handle offsetting this balance and thereby positioning the center of gravity of the cookware towards a rear vertical wall of such cookware proximate the handle positioning. With limited cooking material positioned within the cookware, the cookware tends to tip towards the handle portion and is thereby does not presenting a full cooking surface in association with a conventional heating element, such as in a gas or electric stove. In this connection, there is extensive history of cookware which is utilized to provide efficient and effective cooking of various foods and the like positioned within such cookware. For example, U.S. Pat. No. Des. 230,460 illustrates a conventional cooking pan with a forwardly positioned tab with a hole therethrough apparently for the positioning tab with a like therethrough for storage of the pan. The patent is of interest only in the positioning of a forwardly oriented off-center tab in relation to a frypan. 
     U.S. Pat. No. 1,398,655 to Smith illustrates a turnover pan with a forwardly overlying lip in opposed relationship to a handle whereby the lip is utilized in the patent environment and teaching for the turning of an egg or the like, but the Smith patent does set forth an interesting forwardly oriented offset weight for a different purpose and structure to the instant invention. 
     U.S. Pat. No. 2,788,561 to Mueller sets forth a method of firing pottery with transmitting elements described as firing feet associated with a pan but of incidental construction in the cookware contemplated by Mueller. 
     U.S. Pat. No. 4,352,324 to Noh presents a frying pan with a removable grease catcher for the prevention of the accumulation of hot cooking oil or the like in the utilization of the frying pan. An opening positioned proximate and underlying the handle of the frypan presents itself to an underlying catch basin for the capture of grease but the Noh patent, as is typical of prior art teachings, merely aggravates the already unbalanced condition of the frypan and as typical of such construction, may in fact be dangerous as the grease and hot foods contained within such a frypan effect a greater tendency of the pan to tip. 
     As such, it may be appreciated that there exists a continuing need for a new and improved balanced cookware construction wherein the same presents construction for the balancing of an associated handle attached to such cookware for improved cooking, storage, and ease of use of such cookware, and in this respect, the present invention substantially fulfills this need. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of conventional cookware now present in the prior art, the present invention provides an balanced cookware construction wherein the same provides a forwardly positioned counter-balanced weight sandwiched between walls of an associated cooking utensil which may be readily stored, washed, and enables effective surface contact and, especially, a flat cooking surface with a cooking unit during use.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 7 thereof, a new and improved balanced cookware construction embodying the principles and concepts of the present invention and generally designated by the reference numerals 10 and 10a will be described. 
     More specifically, it will be noted that the balanced cookware construction 10 essentially comprises a conventional cooking utensil which includes a handle 11, a base 12, terminating upwardly into a flare 13 with a wide forward edge flare 14. A peripheral side wall 15 has secured in a forwardmost position a counter-weight 16, as illustrated in FIGS. 4 and 6, in the shallow part of FIG. 1 and a counter-weight 16a in the deeper balanced cookware 10a. The counter-weight 16 of illustration in FIG. 4 and 6 and counter-weight 16a of FIGS. 5 and 7 is sandwiched in a laminated manner between an exterior wall 18 and an interior wall 17, as illustrated in FIGS. 4 and 6. It is contemplated that side wall 15 be divided to form the interior and exterior walls respectively 17 and 18, and 17 and 18a, per FIGS. 5 and 7. If desired, however, the cookware of the instant invention may be formed with a double wall that may simply part at first and second terminal portions 19 and 20, as illustrated in FIG. 6 and 19a and 20a, as illustrated in FIG. 7. 
     The weight of counter-weight 16 or 16a is carefully selected dependent upon the application and may possess a density greater or less than that utilized in the fabrication of the cookware to balance same. With attention to FIG. 4, the selection of the appropriate weight of counter-weight 16 shall be described. M(2) presented as the center of gravity of handle 11 with M(1) as the center of gravity of counter-weight 16. The center of gravity of the central bowl-like portion formed of side walls 15 and base 12 is illustrated centrally positioned as M(3). A typically tipping portion 23 is illustrated as conventional positioning of the fulcrum of a utensil that is prone to tipping. Accordingly, to balance the present moments of force, the equation may be written as follows where: M(1)=(M(2)×L(2))-(M(3)×L(3))/L(1). This equation and the relationship it expresses assumes that the cookware would otherwise balance if the counterweight and handle were not present. 
     However, if this is not the case, the mass and necessary position of the counterweight can still be precisely determined - the mathematics are more complicated is all. 
     In the equation above L(1) is the distance from M(1) to portion 23 and may be expressed as the linear distance between M(1) and portion 23 multiplied by the cosine of angle 22 and L(2) is the distance from M(2) to portion 23 multiplied by the cosine of angle 21. Accordingly, L(3) is the distance from M(3) to portion 23 and is at linear distance multiplied by the cosine of indicated angle 24. To simplify the equation as the acceleration of gravity is constant, the mass in this environment is equal to the weight expressed in a desired form, such as ounces, pounds, etc. 
     It is to be understood the counter-weight material utilized with the instant invention is preferably of a denser material then the material utilized in the construction of the balanced cookware 10. Ideally, the counter-weight 16 will be formed of material of a relatively high melting point preferably greater than that of the boiling point of water. The counter-weight may also be merely formed of the same type of material, be it metal or ceramic, as is the basic cookware 10 forming the base and side wall portions. 
     As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly no further discussion relative to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be restored to, falling within the scope of the invention.
