Golf bag with corrugated internal wall

Abstract

A golf bag including a cylindrical bag body having the structure of a corrugated board, a rigid base plate to close a bottom of the cylindrical bag body, and a rigid frame at an opening of the cylindrical bag body. The corrugations are upright, which strengthens the cylindrical bag body's capacity against distortion. This golf bag has significantly stronger loading capacity than it done by the technology in existence for the same thickness of internal walls; that is to say, under the same circumstances of loading capacity, the thickness of internal wall for this golf bag will be extremely reduced. The corrugations can be either continuous or non-continuous in the circumference direction. The cross sectional shape of the upright corrugations can be arc, rectangles or triangles, each of which having effect to enhance the rigidity of the internal wall.

1 . A golf bag comprising: 
 a cylindrical bag body having an internal wall with a corrugated board structure;    a rigid base plate to close the bottom of the cylindrical bag body; and    a rigid frame at the opening of the cylindrical bag body.    
   
   
       2 . The golf bag as recited in  claim 1 , wherein corrugations of the corrugated board of the internal wall are parallel to a longitudinal axis of the bag body.  
   
   
       3 . The golf bag as recited in  claim 2 , wherein the corrugations of the corrugated board of the internal wall are continuous in a circumference direction of the bag body.  
   
   
       4 . The golf bag as recited in  claim 2 , wherein the corrugations of the corrugated board of the internal wall are non-continuous in a circumference direction of the bag body.  
   
   
       5 . The golf bag as recited in  claim 2 , wherein the corrugations of the corrugated board of the internal wall are intermittent continuous in a circumference direction of the bag body.  
   
   
       6 . The golf bag as recited in  claim 2 , wherein a cross sectional shape of the corrugations of said internal wall are arcs.  
   
   
       7 . The golf bag as recited in  claim 2 , wherein a cross sectional shape of the corrugations of said internal wall are rectangles.  
   
   
       8 . The golf bag as recited in  claim 2 , wherein a cross section of the upright corrugation of said internal wall are triangles.
