DETAILED DESCRIPTION OF THE INVENTION

The following description is provided, so as to enable any person skilled in the art to make use of said invention and sets forth the best modes contemplated by the inventor of carrying out this invention. Various modifications, however, are adapted to remain apparent to those skilled in the art, since the generic principles of the present invention have been defined specifically to provide a method for vertically stacking trays of at least two standard types and a method of using the same.

Reference is now made to FIG. 1, presenting an elemental vertical stack of trays. The aforesaid stack comprises trays of different types 210 and 220 which are vertically spaced apart by means of adapting members 100. The aforesaid members 100 provide stable and reliable connection between the trays of different types 210 and 220.

Reference is now made to FIG. 2, presenting a set of the adapting members 100 which should be disposed at corners of the trays 210/220.

Reference is now made to FIG. 3 presenting a detailed view of an exemplary embodiment of a first terminal 110 of the adapting member 100. In an unlimited manner, the first terminal 110 has a taper head comprising areas 130 and 140 at least two off-axis pins 150 oppositely disposed relative to the axis 190. In accordance with a preferred embodiment of the current invention, the first terminal 110 is received by a matching site in a lower side of the tray (not shown).

Reference is now made to FIG. 4, presenting a detailed view of an exemplary embodiment of a second terminal 120 of the adapting member 100. In an unlimited manner, the second terminal 120 is provided with recesses 170. In accordance with a preferred embodiment of the current invention, the second terminal 120 is received by a matching site in an upper side of the tray (not shown).

It should be emphasized that all adapting members 100 are standard and interchangeable.

Reference is now made to FIG. 5, presenting an open top container for loading, storing and shipping goods in bulk constituting an alternative embodiment of the present invention. A rectangular frame 310 comprises at least four frame members which define a perimeter of the frame. Four legs 300 extend from the four corners of the frame.

A bag has a main portion 320 for accommodating the goods in bulk and a rim portion 330 of the bag. The rim portion 330 is bent over the frame 310 and mechanically secured to outer surface of the main portion 320 of the bag. The portion 320 for accommodating the goods is downwardly housed into the rectangular frame 310 such that goods to be loaded, stored or shipped within the portion 320 can be placed in its internal volume so formed.

An alternative embodiment of the present invention, the rim portion 330 is mechanically secured to the perimeter of the frame 310 (not shown). The legs 300 can be provided with stacking means comprising male and female connectors disposed at opposite terminals thereof (not shown). The bag can be of a rectangular cross-section enlarging from a bottom to said rim portion. The bag is secured to the frame by means of glue, clamps, sutures and any combination thereof.
