Reuseable Spool

Abstract

A reusable spool has a base and an upper flange. The base has a basal flange and an outer tube having a first end, a second end opposite to the first end, and multiple assembling portions. The first end of the outer tube is connected to the basal flange. The multiple assembling portions are connected to the outer tube, disposed adjacent to the second end of the outer tube, and disposed distantly away from the basal flange. The upper flange is screwed with the base and has a plate and a connecting portion. The plate is disposed parallel to and spaced from the basal flange, and abuts against the second end of the outer tube. The connecting portion is formed at a middle portion of the plate and connected to the multiple assembling portions. The reusable spool is refillable and environmentally friendly.

   an upper flange detachably connected to the base and having
 a plate disposed parallel to and spaced from the basal flange, and abutting against the second end of the outer tube; 
 a connecting portion formed at a middle portion of the plate and connected to the multiple assembling portions; and 
   multiple bolts mounted through the upper flange and respectively screwed with the multiple assembling portions.   
     
     
         2 . The reusable spool as claimed in  claim 1 , wherein
 the base has
 an inner tube coaxially disposed within the outer tube; and 
 multiple connecting ribs disposed between the outer tube and the inner tube and connected to both the outer tube and the inner tube; and 
   the multiple assembling portions are disposed between the outer tube and the inner tube, separately arranged around the inner tube, and connected to the inner tube.   
     
     
         3 . The reusable spool as claimed in  claim 2 , wherein
 the multiple assembling portions each respectively have multiple threaded holes;   the connecting portion has multiple screwing holes; and   the multiple bolts are respectively mounted through the multiple screwing holes and respectively screwed with the multiple threaded holes to assemble the base and the upper flange.   
     
     
         4 . The reusable spool as claimed in  claim 3 , wherein
 the inner tube has two opposite ends and multiple engaging recesses separately formed at one of the two opposite ends of the inner tube; and   the connecting portion has multiple engaging protrusions respectively engaging with the multiple engaging recesses.   
     
     
         5 . The reusable spool as claimed in  claim 2 , wherein
 the inner tube has two opposite ends and multiple engaging recesses separately formed at one of the two opposite ends of the inner tube; and   the connecting portion has multiple engaging protrusions respectively engaging with the multiple engaging recesses.   
     
     
         6 . The reusable spool as claimed in  claim 1 , wherein a filament pack is mounted around the outer tube and disposed between the basal flange and the upper flange. 
     
     
         7 . The reusable spool as claimed in  claim 2 , wherein a filament pack is mounted around the outer tube and disposed between the basal flange and the upper flange. 
     
     
         8 . The reusable spool as claimed in  claim 3 , wherein a filament pack is mounted around the outer tube and disposed between the basal flange and the upper flange. 
     
     
         9 . The reusable spool as claimed in  claim 4 , wherein a filament pack is mounted around the outer tube and disposed between the basal flange and the upper flange. 
     
     
         10 . The reusable spool as claimed in  claim 5 , wherein a filament pack is mounted around the outer tube and disposed between the basal flange and the upper flange. 
     
     
         11 . The reusable spool as claimed in  claim 6 , wherein the filament pack has at least one restricting tie wrapped around a filament of the filament pack. 
     
     
         12 . The reusable spool as claimed in  claim 7 , wherein the filament pack has at least one restricting tie wrapped around a filament of the filament pack. 
     
     
         13 . The reusable spool as claimed in  claim 8 , wherein the filament pack has at least one restricting tie wrapped around a filament of the filament pack. 
     
     
         14 . The reusable spool as claimed in  claim 9 , wherein the filament pack has at least one restricting tie wrapped around a filament of the filament pack. 
     
     
         15 . The reusable spool as claimed in  claim 10 , wherein the filament pack has at least one restricting tie wrapped around a filament of the filament pack. 
     
     
         16 . The reusable spool as claimed in  claim 6 , wherein
 the filament pack has a replaceable spool for winding up a filament of the filament pack;   the replaceable spool has
 a tube mounted around the outer tube and having two opposite ends; and 
 two flanges respectively connected to the two opposite ends of the tube. 
   
     
     
         17 . The reusable spool as claimed in  claim 7 , wherein
 the filament pack has a replaceable spool for winding up a filament of the filament pack; and   the replaceable spool has
 a tube mounted around the outer tube and having two opposite ends; and 
 two flanges respectively connected to the two opposite ends of the tube. 
   
     
     
         18 . The reusable spool as claimed in  claim 8 , wherein
