CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims priority to U.S. Provisional Application Ser. No. 61/855,727, filed May 22, 2013. 
     
    
     FIELD OF THE INVENTION 
       [0002]    This invention relates to the field of single serve coffee pods. More specifically, the invention comprises a potentially disposable coffee pod, which allows the user to use it as a scoop and fill the pod themselves with the coffee or tea grounds of their choice and if preferred, freshly ground coffee or tea. It replaces the pre packaged coffee pods lowering the cost of a single serve pod as well as providing more choices and provides an option to use freshly ground coffee. 
       BACKGROUND 
       [0003]    There are limited pre packaged coffee options available in disposable coffee pods, which are expensive relative to bulk purchased coffee. And there are some reusable pod options that allow coffee drinkers to load their own bulk purchased coffee without the convenience and ease provided by the pre packaged coffee options. The reusable options require cleaning after each use and create difficulty to maintaining them. Many do not have the lids attached nor can many have the support necessary to use them to scoop the grounds into their filter cavity nor do they have enough space on the lid to grip the pod so it may be used as a scoop. 
       BRIEF SUMMARY OF THE INVENTION 
       [0004]    The present invention relates to a disposable coffee pod that the user fills with their preferred grounds and is not limited by what is available in pre packaged forms that are available on the market. The Self Fill Disposable Coffee Pod provides a means to brew fresh ground coffee in the single serving coffee makers and to custom mix coffee or tea blends. Additionally, any percentage of decaf coffee may be included in the user&#39;s customized mixture. The invention&#39;s design allows it to be made wholly of cardboard or other fibrous biodegradable material and remain strong enough in structure to be used as a scoop in filling it&#39;s cavity and withstand the pressure and stress applied by a single serve coffee maker. Since the filter cavity can fold or be pressed against the bottom of the lid, the invention can be packaged and stored using less space than many of the hard plastic pods available.

       DETAILED DESCRIPTION 
       [0013]    The following detailed description is merely exemplary in nature and is not intended to limit the described embodiments or the application and uses of the described embodiments. 
         [0014]      FIG. 1  shows a perspective view of the present invention with the hinge lid  12 , that can be a live hinge, raised to an opened position allowing access to the interior of the pod that can be filled with coffee or tea grounds for brewing. The hinge lid  12 , can be a separate shaped cardboard, biodegradable or other material with a sheet of paper or other material adhered to both the hinged lid  12 , and the secured lid portion  18 , with the sheet of paper to be used as the connector and hinge to allow the free moving portion of the lid to open and close. The secured lid portion  18 , is permanently secured to the rim top surface  16 , providing additional strength to the structure and convenience to the user. The permanently secured lid portion  18 , of the top lid may cover as much as seventy five percent of the top lid area or as small of an area as required to still provide the desired strength to the invention. The hinged lid  12 , can be the size and shape able to fit in the space of the top lid which the permanently secured lid portion  18 , does not cover of the top portion of the invention including the area of the rim top surface  16 . The water entry point  10 , provides an area where a coffee maker can penetrate the lid and dispense heated water for brewing of the coffee grounds contained in the pod. The water entry  10 , can be partially carved into the cardboard, biodegradable material or other material of the hinged lid  12 , to allow penetration of the coffee maker so that water can be dispensed into the pod. The water entry  10 , could also be partially carved into the secured lid portion  18 , with the secured lid portion  18 , enlarged to allow the water entry  10 , to be centered in the pod top surface rather than in the hinged lid  12 , as shown in  FIG. 1 . The water entry  10 , may be fully carved or drilled into either the hinged lid  12 , or the secured lid portion  18 , depending on where the centering of the hole is located for the water entry  10 , and may then be covered by a sheet of paper, cardboard, biodegradable material or other material and allow the coffee maker&#39;s penetration to deliver the heated water for brewing. The rim support wall  14 , provides support for the rim top surface  16 , and provides a connection point for the filter material  20 . The rim support wall  14 , may be made from the same sheet of card board, biodegradable material or other material as the rim support wall  14 , by bending down the material while shaping it to the round rim top surface  16 . Making incisions into the rim support wall  14 , could assist in the desired shaping. The filter material  20 , used to prevent the coffee grounds or other brewing material from entering the user&#39;s cup is attached to the inside or outside of the rim support  14  that may utilize an adhesive. The filter material  20 , may be made of cotton, biodegradable material or other material and shaped into a cylinder shape and may be woven, glued or use of other means to reach its desired shape and secured to the rim support wall  14 . A resin, wax, glue or other material that may be biodegradable may be applied to all or parts of the invention to provide additional strength. 
         [0015]      FIG. 2  shows a perspective view of the present invention with the hinged lid  12 , closed. With the pod filled with coffee or other desired brewing substance the Coffee Self Fill Disposable Pod is ready for installation into the coffee maker. 
         [0016]      FIG. 3  shows a top view of the present invention with the hinged lid  12 , opened to a  90  degree angle exposing the cavity of the pod. Shown in the drawing is the rim support wall  14 , with optional dissected lid support sections  28 , to allow for shaping of the rim support wall  14 , to accommodate the round shape of the rim top surface  16 . Also shown is the reinforced filter bottom  22 , which provides added strength for filter material  20 , that may be needed to handle the pressure of the water stream injected into the pod from the coffee maker. The reinforced filter bottom  22 , can be made of cardboard, biodegradable material or other material and may cover a portion or the entire bottom of the filter material  20 . The reinforced filter bottom  22 , may be strengthened with a resin, wax, glue or other material. The reinforced filter bottom  22 , can be different shapes that adequately diffuses the pressured water entering the cavity of the filter material  20 , so that tearing or ripping of the filter material  20 , doesn&#39;t result. The pressured water is diffused once it comes into contact with the reinforced filter bottom  22 . The reinforced filter bottom  22 , may or may not be required for the invention to function satisfactorily. 
         [0017]      FIG. 4  shows a bottom view of the present invention with the filter material  20 , shown and the bottom view of the rim top surface  16 , shown. 
         [0018]      FIG. 5  shows a perspective view of the present invention with tape covering  30 , partially unattached from the adhesive material  32 , which allows the optional securing of the hinged lid  12 , to the rim support wall  14 . The tape covering  30 , for the adhesive material  32 , allows the user to fill the invention with coffee grounds without the grounds adhering to the adhesive material  32 . Once the desired amount and mixture of brewing grounds are placed into the invention&#39;s cavity the tape may be removed and the freely moving hinged lid  12 , can be pressed to the rim top surface  16 , securing it for the brewing process. 
         [0019]      FIG. 6  shows a perspective view of the present invention with the optional shape of the optional lid  24 , that provides a smaller opening for loading coffee grounds for brewing and provides additional strength to the structure due to the increased surface area that is secured on the rim top surface  16 . 
         [0000]    The Self Fill Disposable Coffee Pod can be filled with desired coffee, tea or other substances that may be brewed by the user allowing many more options than what is offered on the market with the pre filled coffee pods. The invention can be composed of cardboard, fiberous or biodegradable material that allows the invention to be compostable. Since the invention can be made to be disposable it could provide more convenience for the user than the reusable coffee pods on the market, that require cleaning and maintaining after use. The Self Fill Disposable Pod can be comprised completely or partially of a material suitable for composting. The design of its partially permanently affixed lid provides additional strength and can be used as a scoop to fill its cavity with coffee or tea grounds directly from a bulk container without the use of a separate spoon, scoop or other implement saving time. The permanently attached portion of its covering lid could be as little as 15% of the pod&#39;s opening or as much as 75% of pod&#39;s opening with the hinged free moving portion of the lid to be of size and shape to fit in the remaining uncovered pod opening and covering the support rim top surface. Buying in bulk can save significant money for the user. The portion of the lid secured to the rim for added strength also provides an area for the user to grip the invention when scooping coffee or tea grounds into its cavity. The attached free moving portion of its lid can be secured after filling the filtered cavity. A tape covering adhesive on the rim can be removed once the pod is filled with preferred coffee or tea grounds and the free moving portion of the lid may be secured to the rim prior to insertion into the coffee maker. The invention&#39;s optional reinforced filter bottom aids in its resistance to tearing when a pressured stream of water is applied by the coffee maker and may be applied to either side of the filter material. The rim may be manufactured from one piece of cardboard in the shape of a circle with the center removed and the inner portion of the ring of cardboard being pressed or bent downward resulting in increased strength for the rim and a connection point for the filter material. The inner portion of the rim may have slits cut into it to allow for desired shaping. This invention reduces time required for its use compared to reusable coffee pods as it is disposable and doesn&#39;t require cleaning, has a pre attached lid and adhesive applied rim for immediate lid attachment after filling the filter cavity. The pod filter can be reinforced at the bottom diffusing the water pressure applied by the coffee maker allowing the filter to require a less strong fibrous filter. A tape covering the adhesive applied to the rim portion can be removed once the coffee or tea grounds are scooped into the invention. Once the lid is pressed down on the exposed adhesive, a secure seal is made. For additional containment of the water in the pod, an additional seal may be placed over or under the manufactured hole in the lid created as the water entry point. 
         [0020]    It is an objective to have a Self Fill Disposable Coffee Pod that can effectively be filled with the user&#39;s coffee or brewing choice and be utilized in a single serve coffee maker. 
         [0021]    It is another object to have a Self Fill Disposable Coffee Pod that can be disposed so cleaning or maintaining after use is not necessary. 
         [0022]    It is another object to have a Self Fill Disposable Coffee Pod, which is reinforced by design so that it can be utilized as a scoop to load coffee grounds in its filter cavity without breaking or bending. 
         [0023]    It is another object to save time by being able to fill the pod with coffee or tea grounds quickly without spillage or waste. 
         [0024]    It is another object to save money by being less expensive to manufacture than many of the pre filled plastic pods. 
         [0025]    It is another object for the invention not to require plastic elements so it can be wholly biodegradable or compostable. 
         [0026]    It is another object to have the Self Fill Disposable Coffee Pod filter reinforced with fibrous or other material at the bottom of the filter portion to prevent pressurized water applied by a single serve coffee maker from forcing a hole in the filter. 
         [0027]    It is another object to have the Self Fill Disposable Coffee Pod have as an option adhesive on its rim where the lid connects when closed to secure the lid which may aid in the brewing process of the single serve coffee maker. 
         [0028]    It is another object for the Self Fill Disposable Coffee Pod to have a top lid that is attached to the rim of the pod saving time for the user. 
         [0029]    It is another object for the Self Fill Disposable Coffee Pod to have a portion of the top lid permanently secured to the rim providing added strength to the rim permitting the pod to be filled by scooping it into the coffee or tea grounds. It also serves as a gripping area for the user&#39;s fingers or thumb.
