Sheet package

Abstract

Provided is a sheet package including a stack of sheets having a plurality of folded sheets and a receptacle for packaging the stack of sheets. The stack of sheets includes first folded sheets and second folded sheets. The first folded sheets and the second folded sheets are alternately stacked in such a manner that the bottom flap portion of the first folded sheet is interfolded with the top flap portion of the second folded sheet, and one pair of the first and second folded sheets and the other pair of the first and second folded sheets next to one pair are so arranged as to interfold the bottom flap portion of the second folded sheet of one pair with the top flap portion of the first folded sheet of the other pair.

What is claimed is:  
     
         1 . A sheet package comprising: 
 a stack of sheets including a plurality of folded sheets arranged in a vertically stacked configuration;    a receptacle for packaging said stack of sheets, said receptacle made of hard or soft material and having a dispensing opening in a top surface thereof;    said stack of sheets including first folded sheets and second folded sheets, each of said first folded sheets having upper and lower central portions folded into two about a first fold line, a top flap portion folded about a second fold line upon said upper central portion, and a bottom flap portion folded about a third fold line under said lower central portion, each of said second folded sheets having a central portion, a top flap portion folded about a fourth fold line upon said central portion, and a bottom flap portion folded about a fifth fold line under said central portion;    wherein said first folded sheets and said second folded sheets are alternately stacked in such a manner that said bottom flap portion of said first folded sheet is interfolded with said top flap portion of said second folded sheet, and one pair of said first and second folded sheets and the other pair of said first and second folded sheets next to said one pair are so arranged as to interfold said bottom flap portion of said second folded sheet of said one pair with said top flap portion of said first folded sheet of said the other pair; and    wherein each of said folded sheets are interfolded so that said top flap portion of each second folded sheet lies between said lower central portion and said bottom flap portion of overlying first folded sheet, and so that said bottom flap portion of each second folded sheet lies between said upper central portion and said top flap portion of underlying second folded sheet.    
     
     
         2 . The sheet package as set forth in  claim 1 , 
 wherein the first fold line of each first folded sheet is located at a position to divide a length of an unfolded sheet into two equal parts so that said upper and lower central portions have substantially equal areas.    
     
     
         3 . A sheet package as set forth in  claim 1 , 
 wherein said top flap portion and said bottom flap portion of each first folded sheet have a length one half or less of that of said top flap portion and said bottom flap portion of each second folded sheet.    
     
     
         4 . A sheet package as set forth in  claim 1 , 
 wherein an overlap portion between said top flap portion of each second folded sheet and said bottom flap portion of each first folded sheet, and an overlap portion between said bottom flap portion of each second folded sheet and said top flap portion of each first folded sheet, are symmetrically arranged about a center line O-O of said stack of sheets.    
     
     
         5 . A sheet package as set forth in  claim 1 , 
 wherein the individual sheets of said first folded sheets are interfolded so that said top flap portion and said bottom flap portion of each odd-numbered sheet and said top flap portion and said bottom flap portion of each even-numbered sheet are prevented from mutually overlapping on the center line O-O.    
     
     
         6 . A sheet package as set forth in  claim 1 , 
 wherein one of said first folded sheets is located at an uppermost position within said receptacle.    
     
     
         7 . A sheet package comprising: 
 a stack of sheets including a plurality of folded sheets arranged in a vertically stacked configuration;    a receptacle for packaging said stack of sheets, said receptacle made of hard or soft material and having a dispensing opening in a top surface thereof, said stack of sheets including; 
 a first W-folded sheet including essentially V-shaped first central portion, a first top flap portion extending from upper end of said first central portion in a first direction and a first bottom portion extending from a lower end of said first central portion in said first direction;  
 a second reversed Z-folded sheet including a substantially straight second central portion, a second top flap portion extending from an upper end of said second central portion in a second direction opposite to said first direction and a second bottom flap portion extending from a lower end of said second central portion in said first direction, said second top flap portion overlapping with said first bottom flap of said first W-folded sheet for interlinking said first W-folded sheet and said second reversed Z-folded sheet so that said second top flap portion is at least partly pulled out of said receptacle through said dispensing opening when said first W-folded sheet is dispensed;  
 a third reversed W-folded sheet including essentially V-shaped third central portion, a third top flap portion extending from an upper end of said third central portion in said second direction and a third bottom flap portion extending from a lower end of said third central portion in said second direction, said third top flap portion overlapping with said second bottom flap portion of said second reversed Z-folded sheet for interlinking said second reversed Z-folded sheet and said third reversed W-folded sheet so that said third top flap portion is at least partly pulled out of said receptacle through said dispensing opening when said second reversed Z-folded sheet is dispensed; and  
 a fourth Z-folded sheet including a substantially straight fourth central portion, a fourth top flap portion extending from an upper end of said fourth central portion in said first direction and a fourth bottom flap portion extending from a lower end of said fourth central portion in said second direction, said fourth top flap portion overlapping with said third bottom flap portion of said third reversed W-folded sheet for interlinking said third reversed W-folded sheet and said fourth Z-folded sheet so that said fourth top flap portion is at least partly pulled out of said receptacle through said dispensing opening when said third reversed W-folded sheet is dispensed;  
   said first W-folded sheet, said second reversed Z-folded sheet, said third reversed W-folded sheet and said fourth Z-folded sheet forming a series; and    said fourth bottom flap portion of one series overlapping with said first top flap portion of said first W-folded sheet of next series for interlinking a plurality of series.
