Offset corrugated sandwich construction

Abstract

A sandwich construction is disclosed that provides alternating offset and jacent corrugated strips secured between upper and lower face sheets. The peaks of one strip are adjacent the troughs of an adjacent strip. The peaks and troughs can have flattened portions and the face sheets can be secured to said portions.

What I claim is: 
     
       1. A sandwich construction comprising: offset corrugated means having a plurality of substantially parallel cells, each cell being formed by alternating peaks and troughs and having moisture communication with each other adjacent cell; and   face sheet means secured to opposite sides thereof.   
     
     
       2. A sandwich construction as described in claim 1 wherein each said peak is substantially flat. 
     
     
       3. A sandwich construction as described in claim 2 wherein each said trough is substantially flat. 
     
     
       4. A sandwich construction as described in claim 3 wherein said face sheet means is attached to the offset corrugated means at the flat peaks and troughs. 
     
     
       5. A sandwich construction comprising: adjacent corrugated strips arranged to have peaks of a first strip substantially next to troughs of a second strip to form an offset pattern; and   upper and lower face sheets secured thereto.   
     
     
       6. A sandwich construction as described in claim 5 wherein said corrugated strips are substantially one-half inch wide.
