Reusable straw storage device

Abstract

A reusable straw storage device includes a storage unit, and a winding unit mounted in said storage unit and rotatable to roll up a reusable straw, enabling the reusable straw to be received in the storage unit in a roll.

What is claimed is: 
     
         1 . A reusable straw storage device, comprising:
 a storage unit comprising an outer casing and a bushing, said outer casing comprising an accommodating space defined therein and at least one placement slot in communication between said accommodating space and the space outside said storage unit, said bushing being mounted in said accommodating space of said outer casing, said bushing comprising an upright dust wall and at least one opening cut through said upright dust wall; and   a winding unit comprising a covering device and a positioning member, said covering device being capped on said outer casing over said accommodating space, said positioning member being connected to said covering device and comprising a plurality of clamping plates suspending in said accommodating space;   wherein said bushing is rotatable in said outer casing between an open position where said at least one opening is kept in alignment with said at least one placement slot, and a close position where said at least one opening is blocked by said outer casing; when said at least one opening is kept in alignment with said at least one placement slot, one end of a reusable straw is insertable through said at least one placement slot and said at least one opening into a gap between said clamping plates of said positioning member for letting the inserted said reusable straw be rolled up by said positioning member upon rotation of said covering device relative to said storage unit and then received inside said storage unit.   
     
     
         2 . (canceled) 
     
     
         3 . (canceled) 
     
     
         4 . The reusable straw storage device as claimed in  claim 1 , wherein said covering device of said winding unit comprises a pivot hole, said positioning member comprises a pivot pivotally coupled to said pivot hole, said pivot comprising a top driven component rotatable by an external force; said clamping plates are downwardly extended from a bottom end of said pivot for rotation with said pivot. 
     
     
         5 . The reusable straw storage device as claimed in  claim 4 , wherein said top driven component of said positioning member is 5 provided with a transverse through hole; said winding unit further comprises an operating plate and a pin, said operating plate comprising a grip portion, two connection portions respectively extended from two opposite ends of said grip portion and disposed at two opposite sides relative to said top driven component of said pivot and a positioning hole located on each said connection portion, said pin being mounted in said transverse through hole and said positioning holes to pivotally connect said operating plate to said positioning member above said covering device, allowing said operating plate to be biased between a horizontal position where said operating plate is closely disposed in contact with a top surface of said covering device and a vertical position where said operating plate is kept perpendicular to said covering device. 
     
     
         6 . The reusable straw storage device as claimed in  claim 1 , wherein said bushing further comprises a base and a pivot hole located on said base, said base being forced integral with a bottom side of said upright dust wall and disposed in said outer casing far from a bottom wall of said accommodating space; said clamping plates are inserted through said pivot hole of said base of said bushing into said accommodating space when said covering device is covered on said outer casing. 
     
     
         7 . The reusable straw storage device as claimed in  claim 1 , wherein said positioning member comprises two said clamping plates, a pivot, a top driven component, a first crown gear and a second crown gear, said clamping plates extending from a bottom edge of said pivot, said first crown gear being located on an opposing top edge of said pivot, said first crown gear comprising a clamping element located at the center thereof and a first series of teeth disposed around a bottom side of said clamping element, said second crown gear being set on a bottom surface of said top driven component, said top driven component comprising an accommodation chamber located at the center of a bottom surface thereof and a locating element suspending in said accommodation chamber, said second crown gear having a through hole, said second series of teeth being disposed around said through hole, said through hole communicating with said accommodation chamber, said first series of teeth being disposed corresponding to said second series of teeth, said locating element being pivotally connected to said clamping element, said covering device being provided with a pivot hole, said pivot being pivoted to said pivot hole, said first series of teeth being engaged with said second series of teeth so that rotating said top driven component causes rotation of said clamping plates. 
     
     
         8 . The reusable straw storage device as claimed in  claim 7 , wherein said top driven component is provided with a transverse through hole; said winding unit further comprises an operating plate and a pin, said operating plate comprising a grip portion, two connection portions respectively extended from two opposite ends of said grip portion and a positioning hole located on each said connection portion, said two connection portion being disposed at two opposite sides of said top driven component, said pin being mounted in said transverse through hole and said positioning hole, said operating plate being liftable from said covering device and operable to rotate said clamping plates relative to said covering device. 
     
     
         9 . The reusable straw storage device as claimed in  claim 1 , wherein said clamping plates each comprise a clamping portion connected to said pivot and a curved tip extended from said clamping portion remote from said pivot, the said curved tips of said two clamping portions being set in a reversed and staggered manner, so that a clamping space is formed between said curved tips of said two clamping portions.
