CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    The present application is a U.S. National Phase of PCT/IL2013/050673 filed on Aug. 8, 2013, the disclosure of which is hereby incorporated by reference into the present Application. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention is related to the field of disposable pans; more specifically but not exclusively, the invention may be applied to the field of disposable baking pans having a baking paper layer. 
       BACKGROUND OF THE INVENTION 
       [0003]    Baking panes come in a variety of shapes and sizes, disposable baking pans are often used for baking and serving foods. As most of the disposable pans are made of aluminum, other disposable pans are sometimes made by partial or by totally recyclable material such as cured cardboards. Although disposable baking pans are designed for cooking purposes, they are often used as trays for serving foods whether hot or cold. 
         [0004]    Baking paper is sometimes referred to by the art as baking parchment is often used to eliminate the need to grease the pans in order to prevent the food from sticking to the pans. Modern baking paper is made by paper rolls rolling through a bath of sulfuric acid or zinc chloride. This process yields a sulfurized cross-linked material with properties such as; high density, stability, and heat resistance, thus having a non-stick quality. Alternatively, the non-stick quality can be obtained by coating a paper with a suitable agent such as silicone having a low surface energy and the capability to withstand high temperatures. Although baking paper can be also used as a wax paper for wrapping sandwiches for example, wax paper cannot be used as baking paper as it lacks the quality to withstand high temperatures. Baking paper is sometimes used for steaming or cooking within closed pouches made from the baking paper itself, a technique which is sometimes referred to as en papillote cooking. Baking paper is usually purchased by the consumer in rolls or in pre-cut rectangle, thereby requiring the user to cut or to fold the baking paper to fit the pan in which it is to be used. Folding the baking paper may be quite tricky as it is somewhat shape remembering material. Some attempts have been made to facilitate the baking procedures associated with baking papers. 
         [0005]    U.S. Pat. No. 5,721,022 to MORITA teaches of two types of disposable pans made from a paper sheet material by press means, particularly designed to prevent its paper configuration from easily deforming or to prevent its bottom portion from easy burning. In order to prevent the paper configuration from deforming, a plurality of folds are provided on the opening divergent part to have the overlapped width small, and/or a synthetic resin is laminated on said paper sheet material. In order to prevent the bottom portion from easily burning, the inner upper surface of said bottom portion is provided with one or plural projections, a metallic foil or sheet is laminated on the outer back surface of said bottom portion, and/or the paper sheet material is impregnated with a surface active agent or the like. 
         [0006]    Japanese patent application JP2010207117 to KEI teaches a process for making a baking paper for preventing the inner surface of a container from directly contacting bread dough, and having a glazed surface with a treating agent for easy peeling off from the formed bread after the maturing treatment. 
         [0007]    U.S. Pat. No. 7,163,120 to BLUCHER teaches of an apparatus, system, and method for forming an improved barrier between a pan and a substance, such as food, contained therein using a contour fit pan liner. The apparatus includes a pan liner having a contoured bottom edge that is custom fit within a food service pan to cover an interior surface of the pan. The contoured edge of the pan liner conforms to the shape and size of the food service pan and does not have any dog ears, ears, or tails that are typical of conventional pan liner. The liner is disposed within the food receptacle area of the pan to cover the interior surface of the pan and the top of the liner is folded over the top opening of the pan. 
         [0008]    The invention hereof improves some of the needs associated with baking containers. 
       SUMMARY OF THE INVENTION 
       [0009]    The invention hereof discloses a disposable baking set made by press means, the disposable baking set may comprise a disposable baking pan and a corresponding baking paper detachably attached to it. The detachable attachment may be achieved merely by placing the disposable baking paper on top of the baking pan or by using a soft adhesive to ensure simple manual detachment of the baking paper form the baking pan if so required. The adhesive may be based on edible material to refrain from an adverse effect should the food come in contact with the remains of the adhesive after detaching the baking paper and reusing the disposable baking pan without the baking paper. 
         [0010]    Few disposable baking sets may be nested one inside of the other to reduce space while shipping and storing a stack of the disposable baking sets. 
         [0011]    The disposable baking pan may include sealing lips to enable manual attachment of a lid to the disposable baking pan. The lid may also be made by baking paper thus enabling steam cooking. The baking paper lid may be substantially in the shape of the baking paper which corresponds to the shape of the baking pan and nests inside the baking pan when not in use. The baking paper lid can be detached from the baking pan or the baking paper over which it rests and placed upside down on top of the baking pan, the baking paper lid can then be manually attached to the baking pan by the baking pan&#39;s attachment lips. 
         [0012]    The disposable baking set may come in a variety of shapes and sizes and may include a few cupcake shaped cavities for baking cupcakes. 
         [0013]    The disposable baking paper may further include precut slits for manually detaching predesigned shapes from the baking paper, thus eliminating the needs to; use scissors or other cutting means, sizing up the required shaped to be cut from the baking paper and shaping the baking paper to try and fit the disposable pan. 
         [0014]    The invention hereof discloses a method for using a set of a disposable baking pan and a detachably attached corresponding disposable baking paper, the method may comprise the following steps: 
         [0015]    a) placing food on the disposable baking set on the surface of the disposable baking paper; cooking or serving the food via the disposable baking set; and 
         [0016]    b) disposing the disposable baking set after the use; or alternatively 
         [0017]    c) detaching the detachably attached baking paper from the baking pan; and 
         [0018]    d) reusing the disposable baking pan.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0027]    For a better understanding of the invention and to show how the same may be carried into effect, reference will now be made, purely by way of example, to the accompanying drawings. With specific reference to the drawings in detail, it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of preferred embodiments of the present invention only, and are presented for the purpose of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the invention. In this regard, no attempt is made to show structural details of the invention in more detail than is necessary for a fundamental understanding of the invention. From the description taken together with the drawings it will be apparent to those skilled in the art how the several forms of the invention may be embodied in practice. Moreover, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting the scope of the invention hereof. 
         [0028]      FIG. 1  schematically shows a disposable pan depicted by the prior art. U.S. Pat. No. 5,721,022 to MORITA teaches of a disposable pan  101  made from a paper sheet material and form a paper having a plurality of wrinkles  102 . 
         [0029]      FIG. 2  schematically shows an apparatus for forming an improved barrier between a pan and food as depicted by the prior art. U.S. Pat. No. 7,163,120 to BLUCHER teaches of an apparatus, system, and method for forming an improved barrier between a pan  201  and a food substance by a plastic liner  202 . 
         [0030]      FIG. 3  schematically shows a perspective view of a disposable pan  301  with a detachable corresponding disposable baking paper  302 . Disposable pan  301  and disposable baking paper  302  have corresponding lips  303  and  304  respectively. Disposable pan  301  and disposable baking paper  302  are attached by an adhesive applied to a few areas  305   a ,  305   b ,  305   c ,  305   d  of disposable pan  301  before disposable baking paper  302  is placed over it during the manufacturing process. The adhesive  305   a - 305   d  is applied to merely hold the baking paper in place and to assist separating a set of a disposable pan  301  with the disposable baking paper  302  from a nested stack of such sets as further depicted in  FIG. 6 . The adhesive  305   a - 305   d  is based on an edible material based on Tylos powder for example. The adhesive can alternatively be sprayed, smeared or applied any other way to the surface, to the sides or to the lips of the disposable container to hold the disposable baking paper  302  in place. The use of a disposable pan  301  together with a corresponding disposable baking paper  302  as a set simplifies the need to cut the disposable baking paper from a roll trying to fold it and to fit it to the contour of a disposable pan. Moreover, the detachability of the baking paper  302  from the disposable pan  301  allows one to use the disposable pan  301  not once but twice. 
         [0031]    That is, the disposable pan can be used once with the baking paper  302  and then again after detaching the baking paper  302  from the disposable pan  301 . Because the edible adhesive  305   a - 305   d  is attached softly to the disposable pan  302  one can simply peel-off the baking paper  302  from the disposable pan  301  to allow another use of the disposable pan  301 . The edible adhesive  305   a - 305   d  ensures that remains of the edible adhesives  305   a - 305   d  over the disposable pan  301  after the disposable baking paper  302  had been peeled-off will not have an adverse effect when coming in direct contact with food placed on the disposable pan  302  during the second use. The disposable pan  301  is made by aluminum; alternatively, the disposable pan  301  can be made by other materials such as paper. 
         [0032]      FIG. 4 a    and  FIG. 4 b    schematically shows a perspective view of a disposable pan  401  with a corresponding disposable baking paper  402  and a corresponding disposable baking paper lid  403 . The disposable pan  402  includes a lip with a vertical contour  404  to allow manual attachment of the disposable baking paper lid  403  to the disposable baking pan  401  if so desired. The attachment of the disposable baking paper lid  403  can be used for steam cooking, sometimes also referred to as en papillote cooking. In this configuration, the food does not come in contact with the disposable pan  401  at all. After the cooking, the user can choose whether to detach the baking paper  402  which is attached to the baking pan by a soft edible adhesive  405  and to reuse the baking pan  401  or to dispose the disposable baking pan  401  along with the disposable baking paper  402  and the disposable baking paper lid  403 . The disposable baking paper lids can be provided with the set of the disposable baking pans with the disposable baking papers or can be provided as a separate stack or manually cut from a baking paper roll. The disposable baking paper pans and their corresponding disposable baking papers and lids can come in variable shapes and sizes, with or without lips and with or without a lip having a vertical contour for attaching a lid. 
         [0033]      FIG. 5 a    and  FIG. 5 b    schematically shows a perspective view of a disposable cupcake pan  501  with a corresponding disposable baking paper  502  having partial precuts in the forms of the cupcakes. The disposable baking paper  502  includes a plurality of cavities which are achieved by a press during the manufacturing process. The disposable baking paper  502  can be attached with a soft heat resistant adhesive to the baking pan  501  or alternatively, placed inside the baking pan  501  without an adhesive, the corresponding cavities between the baking pan  501  and the baking paper  502  will ensure that the baking paper  501  is kept in place. Detaching the baking paper  502  form the baking pan  501  after cooking is much simpler due to the fact that the baking paper  502  is made by a single paper sheet rather than precut cupcake shaped baking papers which are sometimes used. Moreover, detachment of the cupcakes after cooking from the single baking paper  502  sheet is also much simpler due to the same reason.  FIG. 5 b    depicts a set of precut cupcake shaped baking papers  503  which come as a set inside a disposable baking pan  501 , alternatively, the baking paper single sheet  502  can have precut slits around each cavity to allow detachment of individual cupcake shaped baking papers  503  as required. 
         [0034]      FIG. 6 a   - FIG. 6 c    schematically shows a perspective view of sets of disposable pans with corresponding baking paper nesting one inside of the other. Disposable baking trays made of aluminum  601  and having a corresponding disposable baking paper  602  attached to them are provided as sets nested one inside of the other  603 . The nesting of the sets facilitated shipping and storing of large numbers of the disposable pans and liners. In addition, the nesting also ensures that each baking paper is kept in place inside its corresponding baking pan without the need to use adhesives or alternative attachment means.  FIG. 6 b    depicts disposable paper pans  604  with corresponding disposable baking papers  605  nested one inside of the other.  FIG. 6 c    depicts disposable cupcakes paper pans  606  with corresponding disposable cupcake shaped single baking paper sheets  607  nested one inside of the other. 
         [0035]      FIG. 7 a    and  FIG. 7 b    schematically shows a perspective view of disposable pans having two corresponding disposable backing papers one of which serves as a lid when attached upside down to the disposable pan. Disposable pan  701  comes as a set with two corresponding disposable baking papers, one of the disposable baking papers (not shown) is attached on to the disposable baking pan  701  and the other disposable baking paper  702  is turned upside down and attached as a lid to the disposable baking pan  701  via a lip with a vertical contour  703  to allow manual attachment of the disposable baking paper lid  702  to the disposable baking pan  701 . The attachment of the disposable baking paper lid  702  can be used for steam cooking, sometimes also referred to as en papillote cooking. In this configuration, the food does not come in contact with the disposable pan  701  at all. After the cooking, the user can choose whether to detach the baking paper which is attached to the baking pan  701  by a soft edible adhesive (as depicted in  FIG. 4 ) and to reuse the baking pan  701  or to dispose the disposable baking pan  701  along with the disposable baking paper (not shown) and the disposable baking paper lid  702 .  FIG. 7 b    depicts a rounded shaped disposable baking pan  704  with a set of two corresponding disposable baking papers as depicted in  FIG. 7 a    mutatis mutandis.
