     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to re-sealable plastic kitchen bags and, more particularly, to an expandable, foldable device for holding food storage bags during the filling thereof. 
     2. Description of the Related Art 
     The introduction and use of the food storage bag with a plastic zipper-like seal in recent times has been a welcome solution to food storage problems. The ability to completely seal out air from the food storage bag has permitted increased storage times and greater food freshness when compared to other food storage means. As useful as these bags are however, they do have one drawback, in that they are difficult to fill, especially when storing sauces or similar type food products. A person is forced to enlist the help of another to help hold the bag open while filling. This solution however is impractical for those who live alone. Even the manufacturers have begun to address this shortcoming with the recent introduction of flat-bottom storage bags, with a higher cost of course. 
     A search of the prior art did not disclose any patents that read directly on the claims of the instant invention; however, the following references were considered related. 
     The following patents disclose a food storage bag holder for supporting the bag in an open position: 
     U.S. Pat. No. 5,416,834 issued in the name of Bales et al. 
     U.S. Pat. No. 4,975,941 issued in the name of Morganstein et al. 
     The following patents describe the design and function of a holding device for sacks or the like to keep them open: 
     U.S. Pat. No. 5,380,081 issued in the name of Vogt 
     U.S. Pat. No. 4,469,300 issued in the name of Valesko 
     U.S. Pat. No. 4,322,048 issued in the name of Vollman

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The best mode for carrying out the invention is presented in terms of its preferred embodiment, herein depicted within the Figures. 
     1. Detailed Description of the Figures 
     Referring now to FIG. 1, a re-sealable food storage bag filling device  10  is shown in a utilized state, according to the preferred present invention. All components of the invention may be made of steel, plastic, nylon, or similar material, or a combination thereof. The main supporting structure of the invention is formed by a first “X”-shaped support stand  15  and a second “X”-shaped support stand  20 , which stand in a vertical position, directly fore and aft, respectively. The furthest members of each arm on the first “X”-shaped support stand  15  and the second “X”-shaped support stand  20  are joined together by a pair of fixed connecting rods  25  on the bottom and a pair of adjustable connecting rods  30  on the top. The fixed connecting rods  25  are held to the first “X”-shaped support stand  15  and the second “X”-shaped support stand  20  by a mechanical fastening method such as adhesive, press-fitting or the like, depending on the material of construction. The adjustable connecting rods  30  are held to the first “X”-shaped support stand  15  and the second “X”-shaped support stand  20  by a series of sliding adjustment knobs  35  which will be described in greater detail herein below. The sliding adjustment knobs  35  thus allows each adjustable connecting rods  30  to slide up and down in a slot  40  which is provided in both the first “X”-shaped support stand  15  and the second “X”-shaped support stand  20 . This path of travel is indicated by a first travel path  45  and a second travel path  50  which operate independent of one another. On each adjustable connecting rod  30 , there is a pair of spring operated bag clips  55  provided which are permitted to slide along the cylindrical shape of the adjustable connecting rods  30  as depicted by a third travel path  60 , of which only one of two is shown for sake of clarity. At the crossover point of the first “X”-shaped support stand  15  and the second “X”-shaped support stand  20 , a clamping adjustment knob  65  is provided. The clamping adjustment knob  65  provides for a width adjustment of the re-sealable food storage bag filling device  10  to accommodate various size storage bags as will be shown herein below, as well as to collapse the re-sealable food storage bag filling device  10  for storage. In the fully open position, the adjustable connecting rods  30  as well as the fixed connecting rods  25  are furthest apart from one another and capable of receiving the largest storage bag. In their closed position, the adjustable connecting rods  30  and the fixed connecting rods  25  are in close proximity, so as to be almost touching one another. 
     Referring next to FIG. 2, a re-sealable food storage bag  70  is located on the interior of the re-sealable food storage bag filling device  10  and is shown in an upright and open manner. The re-sealable food storage bag  70  is envisioned to be of the type with a continuous joining strip or “zipper” along its opening, though it can be seen that virtually any type of food storage bag could be used with equal effectiveness. The re-sealable food storage bag  70  is held open by the four spring operated bag clips  55  in such a stance as to allow food items such as sauces, vegetables, pasta, fruit and the like as well as virtually any item commonly stored in plastic bags to be used. The spring operated bag clips  55  form no permanent degradation of the re-sealable food storage bag  70  and thus allow it to be used over and over again. 
     Referring next to FIG. 3, a sectional view, as seen along a line I—I as seen in FIG. 1, is depicted. This FIG., depicts the first “X”-shaped support stand  15  in partial view, and is directly applicable to the second “X”-shaped support stand  20  utilizing a mirror reference. The first “X”-shaped support stand  15  is comprised of a first arm  75  and a second arm  80 , which are in close sliding contact with one another around a rotational center point defined by locking shaft  85 . The locking shaft  85  is provided with a retaining cap  90  in much the same manner as a conventional screw. The locking shaft  85  is provided with an outer covering of threads, which extend through a hole  95  in both the first arm  75  and the second arm  80 . The clamping adjustment knob  65  then engages these threads, and with a rotational action of the clamping adjustment knob  65 , thus allows for the securement of the first arm  75  and the second arm  80  in a fixed position, which can be adjusted at a later point by simply reversing the rotational action of the clamping adjustment knob  65 . Such action would be performed on both clamping adjustment knob  65  on the first “X”-shaped support stand  15  and the second “X”-shaped support stand  20  (as shown in FIG. 1) in an identical manner, to provide for symmetry of the re-sealable food storage bag filling device  10  (as shown in FIG. 1) 
     Referring now to FIG. 4, a sectional view as seen along a line II—II as seen in FIG. 2 is depicted. The end of the sliding adjustment knobs  35  is provided with exterior threads  100  which engages an interior locking nut  105 . An interior washer  110  is provided next on the sliding adjustment knobs  35 , next to the interior locking nut  105  to increase contact surface area and associated friction with the second arm  80 . On the opposite side of the second arm  80 , an exterior washer  115  and the sliding adjustment knobs  35  is provided. This arrangement allows placement adjustment of the sliding adjustment knobs  35  anywhere along the slot  40  (not shown in this FIG.) of the second arm  80 , by a simple rotational loosening of the sliding adjustment knobs  35  and the subsequent sliding of the sliding adjustment knobs  35  to an infinitely variable position. When said position is reached, the sliding adjustment knobs  35  is simply tightened in a conventional matter to hold the sliding adjustment knobs  35  in position by a friction fit. Such action would be performed on all four sliding adjustment knobs  35  as shown in FIG.  1 . 
     Referring finally to FIG. 5, an isomeric view of the re-sealable food storage bag filling device  10  shown in a collapsed state for storage is shown. Such a depicted state would be used when storing the re-sealable food storage bag filling device  10  in a kitchen cabinet or drawer. It would also be useful when transporting the re-sealable food storage bag filling device  10  from one location to another such as to and from a work site or harvest area on a farm or where canning was being done. The collapsed state of the re-sealable food storage bag filling device  10  is obtained by loosening both clamping adjustment knob  65  and allowing the first “X”-shaped support stand  15  and second, “X”-shaped support stand  20  to collapse on itself in a scissor-like fashion. 
     2. Operation of the Preferred Embodiment 
     The present invention is designed with ease of operation features in mind that allow it to be setup and utilized by a common individual with little or no training. To use the present invention, the user simply clips the re-sealable food storage bag  70  into the re-sealable food storage bag filling device  10  using the four spring operated bag clips  55 . The re-sealable food storage bag  70  is then opened or spread to the desired position, followed by the action of locking the two clamping adjustment knob  65 , thus setting the opening width. The user then adjusts the re-sealable food storage bag filling device  10  to the desired height by using the four sliding adjustment knobs  35  to adjust the placement of the two adjustable connecting rods  30 . At this point the user is ready to begin filling the re-sealable food storage bag  70  with the desired contents such as food or other material. 
     When filled, the process is reversed, by first loosening the two clamping adjustment knob  65  and closing the re-sealable food storage bag filling device  10  in a scissor-like manner. The user may then systematically remove the four spring operated bag clips  55  while closing or “zipping” the bag close. Portions of the bag that are not yet closed, would be held together by the re-sealable food storage bag filling device  10  thus yielding additional assistance to the user.
