Freezer Rack

Abstract

Liquids are frozen and stored in a freezer in individual flexible sealable plastic bags by providing a storage rack comprising a frame having flat bottom and sides and a plurality of removable flat shelves which can be inserted into the frame to lie parallel to the bottom. The frame is placed into the freezer with the bottom and shelves horizontal with the bags on the shelves for freezing so that the liquid freezes with a flat bottom. The sides of the frame and the shelves are perforated with holes to allow penetration of cooled air within the freezer with the holes.

1 . A method for storing liquids in a freezer comprising:
 storing the liquids in individual flexible sealable plastic bags;   providing a storage rack comprising a frame having at least a flat bottom and sides and a plurality of flat shelves one or more of which is removable which can be inserted into the frame to lie parallel to the bottom;   inserting the frame into the freezer with the bottom and shelves horizontal;   placing the freezer bags on the shelves for freezing;   the sides of the frame and optionally the shelves being perforated with holes to allow penetration of cooled air within the freezer with the holes;   and placing a bag containing liquid on the bottom and/or shelves so that the liquid freezes with a flat bottom.   
     
     
         2 . The method according to  claim 1  including labelling the shelves to identify the liquids. 
     
     
         3 . The method according to  claim 1  including storing the liquid in the bags on the shelves. 
     
     
         4 . The method according to  claim 1  including removing some of the shelves to store the bags directly on top of one another. 
     
     
         5 . The method according to  claim 1  wherein the bottom and sides are perforated to allow cooling air to pass. 
     
     
         6 . The method according to  claim 1  wherein the frame includes top and rear panels which are perforated to allow cooling air to pass. 
     
     
         7 . The method according to  claim 1  wherein the frame includes a top locating tab arrangement to enable stacking. 
     
     
         6 . The method according to  claim 1  wherein the shelves slide into slots in the sides. 
     
     
         7 . The method according to  claim 1  wherein the shelves include a flat front edge wider than the thickness of the shelf for receiving labels. 
     
     
         8 . The method according to  claim 1  wherein each shelf has a width of the order of 18 to 20 cms to receive a single bag across the full width. 
     
     
         9 . The method according to  claim 1  wherein the shelves are tapered toward the rear. 
     
     
         10 . The method according to  claim 1  wherein each shelf has a length of the order of 20 cms. 
     
     
         11 . The method according to  claim 1  including, after freezing is complete, turning the frame and shelves to a vertical orientation to store the bags therebetween. 
     
     
         12 . The method according to  claim 1  including, after freezing is completed, storing the bags in directly side by side relationship with the flat sides in contact. 
     
     
         13 . The method according to  claim 1  wherein the shelves are perforated with holes.
