Switching structure capable of changing a discharging amount of a soft tube package

Abstract

A switching structure outer capable of changing a discharging amount of a soft tube package comprises a connecting head and an outer cap. A switching cap is movably disposed on the connecting head. At least one arch-shaped hook is formed on an outer peripheral wall of the connecting head. The connecting head has a neck which forms a seat downward from an upper end thereof Through holes are formed at a bottom of the seat, and a protrusion is disposed at a center of the seat. The switching cap includes a large cover fitting the arch-shaped hook and a small cover formed inside the large cover. A discharge outlet is formed at a center of the switching cap. This switching structure is capable of controlling an extruding amount of contents of the soft tube package effectively.

I claim: 
     
         1 . A switching structure capable of changing a discharging amount of a soft tube package comprising a connecting head integrated with a soft tube body and an outer cap covering said connecting head, wherein a switching cap is movably disposed on said connecting head, at least one arch-shaped hook being formed on an outer peripheral wall of said connecting head, a neck with external threads being disposed on said connecting head, said neck forming a seat which goes downward from an upper end thereof, through holes being formed at a bottom of said seat and communicating with said soft tube body, a protrusion being disposed at a center of said seat and having an upper surface disposed level with an upper edge of said neck, said switching cap being a cover body which covers said connecting head and including a large cover and a small cover, said large cover forming an inner wall on which a locking part is formed to fit said arch-shaped hook and having a depth corresponding to a height of said connecting head, said small cover with internal threads being formed inside said large cover and disposed to engage with said neck, a discharge outlet being formed at a center of said switching cap and providing an inner diameter smaller than an outer diameter of said protrusion. 
     
     
         2 . The switching structure capable of changing the discharging amount of the soft tube package as claimed in  claim 1 , wherein said connecting head includes a step portion opposite to said soft tube body and a shoulder post formed when said step portion has a reduced diameter, a flange being formed on an outer peripheral wall of said shoulder post to lock with said outer cap. 
     
     
         3 . The switching structure capable of changing the discharging amount of the soft tube package as claimed in  claim 2 , wherein a reduced diameter seat is formed on said shoulder post, said at least one arch-shaped hook being disposed on an outer peripheral wall of said reduced diameter seat, said neck being formed on said reduced diameter seat. 
     
     
         4 . The switching structure capable of changing the discharging amount of the soft tube package as claimed in  claim 3 , wherein said large cover of said switching cap is disposed to face said shoulder post, an inner diameter of said large cover matching to an outer diameter of said reduced diameter seat, a depth of said large cover corresponding to a height from said reduced diameter seat to a top end of said connecting head. 
     
     
         5 . The switching structure capable of changing the discharging amount of the soft tube package as claimed in  claim 1 , wherein said switching cap has a plurality of annular grooves formed on a top surface thereof. 
     
     
         6 . The switching structure capable of changing the discharging amount of the soft tube package as claimed in  claim 1 , wherein a functional head is mounted on said switching cap. 
     
     
         7 . The switching structure capable of changing the discharging amount of the soft tube package as claimed in  claim 6 , wherein said switching cap has a plurality of annular grooves formed on a top surface thereof. 
     
     
         8 . The switching structure capable of changing the discharging amount of the soft tube package as claimed in  claim 1 , wherein a concave-convex pattern is arranged on an outer peripheral wall of said switching cap for rotating easily.
