BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to adjustable volume and collapsible containers and more particularly pertains to a new adjustable container for providing a storage container whose volume may be adjusted to suit the size and amount of items held therein. 
     2. Description of the Prior Art 
     The use of adjustable volume containers is known in the prior art. More specifically, adjustable volume and collapsible containers heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements. 
     Known prior art adjustable volume and collapsible containers include U.S. Pat. No. 4,157,103; U.S. Pat. No. 5,333,761; U.S. Pat. No. 5,407,093; U.S. Pat. No. Des. 347,359; U.S. Pat. No. 5,447,110; and U.S. Pat. No. 4,865,211. 
     While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new adjustable container. The inventive device includes a base with a perimeter side wall extending around the base outer perimeter to define an interior space.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new adjustable container embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     As best illustrated in FIGS. 1 through 4, the adjustable container 10 generally comprises a base 12 with a perimeter side wall 16 extending around the base 12 outer perimeter to define an interior space. The perimeter side wall 16 has a height (defined between the terminal edge 19 of the perimeter side wall 16 and the base 12) which is adjustably extendible to increase or decrease the volume of the interior space. A removable lid 24 is provided for substantially covering the opening into the interior space. 
     In closer detail, the base 12 is generally rectangular and has generally planar first and second surfaces 13,14. The base 12 also has a pair of lateral sides and a pair of longitudinal sides extending between the lateral sides of the base 12 with a corner being formed between each intersection of adjacent lateral and longitudinal sides. Together, the lateral and longitudinal sides of the base 12 defining a base outer perimeter. Ideally, the lengths of the lateral sides of the base 12 are substantially equal to the lengths of the longitudinal sides of the base 12 so that the base is generally square in shape. 
     The perimeter side wall 16 is outwardly extended from first surface 13 of the base 12 around the base outer perimeter. The perimeter side wall 16 defines the interior space of the container. The interior space is designed for containing items in it. The perimeter side wall 16 has inner and outer surfaces, a terminal edge 19, and preferably a plurality of rectangular side panels 20 with a corner edge located between each adjacent pairs of the side panels 20. The terminal edge 19 of the perimeter side wall 16 defines an opening into the interior space. The perimeter side wall 16 has a height which is defined between the terminal edge 19 of the perimeter side wall 16 and the base 12. The height is adjustably extendible such that the volume of the interior space may be adjustably increased and decreased. To permit this adjustable extension of the perimeter side wall 16, the perimeter side wall 16 preferably has a pleated portion 21 extending around it. The pleated portion 21 has a plurality of longitudinal folds that are arranged in an accordion fashion between the base 12 and the terminal edge 19 of the perimeter side wall 16. With reference to FIG. 3, the perimeter side wall 16 has a sealing ridge 22 extending around it, preferably from the outer surface 18 of the perimeter side wall 16. The sealing ridge 22 is preferably located adjacent the terminal edge 19 of the perimeter side wall 16. 
     The removable lid 24 substantially covers the opening into the interior space. The lid 24 is generally rectangular and has an outer perimeter, inner and outer surfaces 25,26, and a plurality of corners. In the preferred embodiment of the invention, the corners of the base 12 and lid 24 are rounded as well as the corners edges of the perimeter side wall 16. 
     The outer perimeter of the lid 24 has a lip 27 which is extended around it. A first portion of the lip 27 is outwardly extended from the inner surface 25 of the lid 24 while preferably, a second portion of the lip 27 outwardly extends from the outer surface 26 of the lid 24. The first portion of the lip 27 is positionable adjacent the outer surface of the perimeter side wall 16 around the terminal edge 19 of the perimeter side wall 16 when the lid 24 is covering the opening into the interior space. In the preferred embodiment, the first portion of the lip 27 has a groove 28 extending around it which is matingly engagable to the ridge 22 of the perimeter side wall 16 when the lid 24 is covering the opening into the interior space. This engagement forms a substantially air tight seal between the groove 28 and the ridge. This air tight seal helps to hold the height of the perimeter side wall 16 in place by air pressure in the interior space. The second portion of the lip 27 is adapted for accepting a base 12 of another the container therein such that a plurality of the containers 10 may be easily stacked upon each other. 
     As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating 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 resorted to, falling within the scope of the invention.
