Stackable bottle system

Abstract

A bottle having a storage chamber defined by spaced upper and lower surfaces and planar sidewalls; a conical ceiling in said upper surface having an opening at the top thereof; a conical convex recess in said lower surface for receiving the conical ceiling of the next adjacent bottle when stacking said bottles, and means for interlocking the sides and upper and lower surfaces of the bottles when stacked.

1 . A system of interlocking storage bottles comprising: 
 (a) a plurality of storage bottles, each bottle having a storage chamber with an upper surface, a lower surface and at least four generally planar side walls;    (b) a central conical ceiling extending upwardly from the upper surface;    (c) a cylindrical neck extending from the center of the ceiling having an opening at its top end and protrusions for attachment thereto of a cap;    (d) a conical recess in the lower surface of a size sufficient to envelop the ceiling, neck, and a cap of another storage bottle insertable therein;    (e) vertical interlocking means for releasably connecting each side wall to the side wall of another storage bottle stackable adjacent thereto;    (f) horizontal interlocking means for releasably connecting the upper surface to the lower surface of another storage bottle disposable thereabove.    (g) at least one indentation to form a handle    
   
   
       2 . The system of interlocking storage bottles of  claim 1  wherein each storage bottle may be stacked in an upright position above, below or beside another upright storage bottle to for a stable bottle stack.  
   
   
       3 . The system of interlocking storage bottles of  claim 1  further comprising at least one indentation in each of at least two adjacent side walls to form a handle.  
   
   
       4 . The system of interlocking storage bottles of  claim 1  further comprising a recess in at least one side wall for application thereto of a label.  
   
   
       5 . The system of interlocking storage bottles of  claim 1  wherein each of the storage bottles is manufactured of a PET plastic material.  
   
   
       6 . The system of interlocking storage bottles of  claim 1  wherein the vertical interlocking means comprises at least one recess on the side wall for engaging a corresponding protrusion on the side wall of another storage bottle.  
   
   
       7 . The system of interlocking storage bottles of  claim 1  wherein the horizontal interlocking means comprises at least one recess in the lower surface for engaging a corresponding protrusion on the upper surface of another storage bottle.  
   
   
       8 . The system of interlocking storage bottles of  claim 1  wherein the bottles in the stack of bottles are fillable with a consumable material.  
   
   
       9 . The system of interlocking storage bottles of  claim 1  wherein the bottles in the stack of bottles further comprises ribs in the conical ceiling to improve bottle strength.  
   
   
       10 . The system of interlocking storage bottles of  claim 1  wherein the bottles in the stack of bottles further comprises ribs in the conical ceiling and in the conical recess to improve bottle strength.  
   
   
       11 . A consumables storage bottle having a storage chamber, a conical ceiling in an upper surface, a lower surface, and at least four generally planar side walls comprising: 
 (a) a cylindrical neck extending upwardly from the center of the conical ceiling and having an opening at its top end and protrusions for attachment thereto of a cap;    (b) a conical recess extending upwardly from the lower surface of a size sufficient to envelop the ceiling, neck and a cap of another storage bottle insertable therein;    (c) vertical interlocking means for releasably connecting each side wall to the side wall of another storage bottle stackable adjacent thereto;    (d) horizontal interlocking means for releasably connecting the upper surface to the lower surface of another storage bottle disposable thereabove.    
   
   
       12 . The storage bottle of  claim 11  further comprising at least one indentation in each of two adjacent side walls to form a handle.  
   
   
       13 . The storage bottle of  claim 11  wherein the vertical interlocking means comprises at least one recess on the side wall for engaging a corresponding protrusion on the side wall of another storage bottle.  
   
   
       14 . The storage bottle of  claim 11  wherein the horizontal interlocking means comprises at least one recess in the lower surface for engaging a corresponding protrusion on the upper surface of another storage bottle.  
   
   
       15 . The storage bottle of  claim 11  wherein each of the bottles is blow-moulded.  
   
   
       16 . A bottle as claimed in  claim 11  further comprising ribs to improve bottle strength and allow the bottle to be collapsible at the end of the life cycle.  
   
   
       17 . A bottle as claimed in  claim 16  wherein the ribs are located within the conical ceiling and the conical recess.  
   
   
       18 . An assembly comprising a plurality of the bottles of  claim 16 , wherein only the side walls of each bottle are adjacent each other bottle, to form a generally quadrilateral assembly.  
   
   
       19 . The assembly of  claim 18 , further comprising at least one band of a flexible wrapping material encircling the exposed side walls of the assembly.  
   
   
       20 . The assembly of  claim 19 , further comprising a strap of a flexible material extending between opposed sides of the assembly, each end of the strap connected to the band to form a handle for the assembly.
