Discharging contents from a container while filling the same with gas

Abstract

Disclosed is a bottle for containing liquid content including a body portion, at least part or the entire portion of an upper portion of which is provided with a plurality of guides which protrudes inward from an inside surface thereof and is in a spiral pattern so that the liquid content can be guided towards an opening of a neck portion of the bottle while spirally revolving inside the bottle.

What is claimed is: 
     
         1 . A method of stably discharging liquid contents out of a bottle which includes a body portion and a neck portion, wherein said body portion defines an enclosed interior space and has an inside surface and wherein said neck portion extends from one end of said body portion and then terminates at an opening through which said liquid contents are discharged when said bottle is tilted, said method comprising the steps of:
 extending a plurality of guides along a longitudinal axis of said bottle by protruding inwardly into said body portion from said inside surface;   arranging said guides in a spiral pattern around said axis;   tilting said bottle; and   discharging said liquid contents out of said bottle through said opening while guiding said liquid contents along said guides and exerting centrifugal force on said liquid contents, thereby allowing ambient air to stably flow into said interior of said bottle through said opening and away from said guides during said discharging for said stably discharging.   
     
     
         2 . The method of  claim 1 , wherein said stably discharging includes one of the steps of:
 minimizing abrupt discharging of said liquid contents out of said bottle;   preventing abrupt discharging of said liquid contents out of said bottle;   minimizing gushing of said liquid contents out of said bottle; and   preventing gushing of said liquid contents out of said bottle.   
     
     
         3 . The method of  claim 1 , wherein said stably discharging includes one of the steps of:
 facilitating said allowing said air to stably flow into said interior; and   maximizing said allowing said air to stably flow into said interior.   
     
     
         4 . The method of  claim 1 , wherein said extending includes one of the steps of:
 starting said extending from another end of said body portion wherein said another end is opposite to said one end;   starting said extending from about a middle of said body portion; and   starting said extending from a location of body portion, said location closer to said one end than said another end.   
     
     
         5 . The method of  claim 1 , wherein said terminating includes one of the steps of:
 ending said extending on said opening;   ending said extending proximate to said opening; and   ending said extending in a preset distance from said opening.   
     
     
         6 . The method of  claim 1  further comprising the steps of:
 performing said protruding in such a way that cross-sections of at least some of said guides have asymmetrical shapes each having a shallow portion and a deep portion; and 
 performing said guiding in such a way that more amount of said liquid contents are guided by said deep portion than said shallow portion, thereby enhancing said stably discharging. 
 
     
     
         7 . A method of stably discharging liquid contents out of a bottle which includes a body portion and a neck portion, said body portion defining an inside surface, while said neck portion extending from one end of said body portion and terminating at an opening through which said liquid contents are discharged, said method comprising the steps of:
 extending a plurality of guides along a longitudinal axis of said bottle by protruding into said body portion from said inside surface;   arranging said guides in a spiral pattern around said axis; and   discharging said liquid contents out of said bottle through said opening while guiding said liquid contents toward said opening along said guides and exerting centrifugal force on said liquid contents, thereby allowing ambient air to stably flow into said bottle through said opening during said discharging for said stably discharging.   
     
     
         8 . The method of  claim 7 , wherein said allowing includes the step of allowing ambient air to flow into said interior of said bottle. 
     
     
         9 . The method of  claim 7 , wherein said stably discharging includes one of the steps of:
 minimizing abrupt discharging of said liquid contents out of said bottle;   preventing abrupt discharging of said liquid contents out of said bottle;   minimizing gushing of said liquid contents out of said bottle; and   preventing gushing of said liquid contents out of said bottle.   
     
     
         10 . The method of  claim 7 , wherein said stably discharging includes one of the steps of:
 facilitating said allowing said air to stably flow into said interior; and   maximizing said allowing said air to stably flow into said interior.   
     
     
         11 . The method of  claim 7 , wherein said extending includes one of the steps of:
 starting said extending from another end of said body portion wherein said another end is opposite to said one end;   starting said extending from about a middle of said body portion; and   starting said extending from a location of body portion, said location closer to said one end than said another end.   
     
     
         12 . The method of  claim 7 , wherein said terminating includes one of the steps of:
 ending said extending on said opening;   ending said extending proximate to said opening; and   ending said extending in a preset distance from said opening.   
     
     
         13 . The method of  claim 7 , wherein said stably discharging includes the steps of:
 discharging said liquid contents along said guides and closer to said inside surface; and   preventing said opening from being blocked by said liquid contents, thereby creating a path for said air to stably flow into said bottle.   
     
     
         14 . The method of  claim 7 , wherein said stably discharging includes the steps of:
 discharging said liquid contents along said guides in said spiral pattern;   subjecting said liquid contents to a centrifugal force; and   preventing said opening from being blocked by said liquid contents under said centrifugal force, thereby creating a path for said air to stably flow into said bottle.

         16 .
