Abstract

A compressed coreless rolled product is described, including an inner surface defining a central cavity having an inner diameter and an outer surface having an outer diameter larger than the inner diameter. The outer diameter is at least five inches and a ratio of the inner diameter to the outer diameter is at least 0.35. Also described is a compressed coreless rolled product with similar inner and outer surfaces, wherein: a difference between the outer diameter and the inner diameter defining a thickness of at least 2.9 inches; and a ratio of the inner diameter to the outer diameter is at least 0.35. An associated method of producing the product is also described, including steps of: winding an absorbent sheet around a forming core member; removing the forming core member to form a coreless rolled product with a diameter ratio of at least 0.35; and compressing the product.

Claims

exact text as granted — not AI-modified
1 . A compressed coreless rolled product comprising:
 an inner surface defining a central cavity having an inner diameter; and   an outer surface having an outer diameter larger than the inner diameter,   wherein:
 the outer diameter is at least five inches; and 
 a ratio of the inner diameter to the outer diameter is at least 0.35. 
   
     
     
         2 . The product of  claim 1 , wherein the inner diameter is at least 1.75 inches. 
     
     
         3 . The product of  claim 1 , wherein the inner diameter ranges from 1.75 to 4.0 inches. 
     
     
         4 . The product of  claim 1 , wherein the inner diameter is at least 2.0 inches. 
     
     
         5 . The product of  claim 1 , wherein the inner diameter is 2.0 inches and the outer diameter is 5.0 inches. 
     
     
         6 . The product of  claim 1 , wherein the inner diameter is between 2.0 and 3.0 inches. 
     
     
         7 . The product of  claim 6 , wherein the inner diameter is 2.50 inches. 
     
     
         8 . The product of  claim 1 , wherein the outer diameter is 5.6 inches and the ratio is 0.36. 
     
     
         9 . The product of  claim 1 , wherein the outer diameter is 7.0 inches and the ratio is 0.40. 
     
     
         10 . The product of  claim 1 , wherein the outer diameter is between 7.0 and 12.0 inches. 
     
     
         11 . A compressed coreless rolled product comprising:
 an inner surface defining a central cavity having an inner diameter; and   an outer surface having an outer diameter larger than the inner diameter,   wherein:
 a difference between the outer diameter and the inner diameter defining a thickness of at least 2.9 inches; and 
 a ratio of the inner diameter to the outer diameter is at least 0.35. 
   
     
     
         12 . The product of  claim 11 , wherein the thickness is at least 4.0 inches. 
     
     
         13 . The product of  claim 11 , wherein the thickness is between 3.0 and 12.0 inches. 
     
     
         14 . The product of  claim 11 , wherein the thickness is 5.0 inches. 
     
     
         15 . The product of  claim 11 , wherein the thickness is 3.25 inches. 
     
     
         16 . The product of  claim 11 , wherein the ratio is at least 0.40. 
     
     
         17 . A method of producing a compressed coreless rolled product, the method comprising the steps of:
 winding an absorbent sheet around a forming core member until a rolled product having an outer diameter of at least five inches is formed;   removing the forming core member from the rolled product to form a coreless rolled product having a hollow central cavity with an inner diameter, a ratio of the inner diameter to the outer diameter being at least 0.35; and   compressing the coreless rolled product such that the hollow central cavity is substantially collapsed.   
     
     
         18 . The method of  claim 17 , wherein the forming core member is a tubular paperboard core. 
     
     
         19 . The method of  claim 18 , wherein the tubular paperboard core is re-usable. 
     
     
         20 . The method of  claim 17 , wherein a difference between the outer diameter and the inner diameter defines a thickness, the thickness being 3.0 and 12.0 inches. 
     
     
         21 - 25 . (canceled)
