Eyelash curler

Abstract

An eyelash curler comprises a palm part ( 101 ) having a first end and a second end, a direction from said first end towards said second end defining a longitudinal direction ( 103 ), and a movable part ( 102 ) having a first end and a second end, attached to said palm part ( 101 ) with a sliding joint that enables movement of the movable part ( 102 ) with respect to said palm part ( 101 ) in said longitudinal direction ( 103 ). There are a first curling surface ( 104 ) at said first end of the palm part ( 101 ) and a second curling surface ( 105 ) at said first end of the movable part ( 102 ), configured to engage at least part of said first curling surface ( 104 ) upon said movement of the movable part ( 102 ). An electric heating element ( 712 ) is configured to heat said second curling surface ( 105 ). The eyelash curler comprises a battery compartment ( 702 ) for receiving a battery, and a control circuit ( 1801 ) configured to control the flow of electric current between a battery received in said battery compartment ( 702 ) and said electric heating element ( 712 ). Said electric heating element ( 712 ), said battery compartment ( 702 ), and said control circuit ( 1801 ) are allocated in said movable part ( 102 ).

1 . An eyelash curler, comprising:
 a palm part having a first end and a second end, a direction from said first end towards said second end defining a longitudinal direction,   a movable part having a first end and a second end, attached to said palm part with a sliding joint that enables movement of the movable part with respect to said palm part in said longitudinal direction,   a first curling surface at said first end of the palm part,   a second curling surface at said first end of the movable part configured to engage at least part of said first curling surface upon said movement of the movable part,   an electric heating element configured to heat said second curling surface,   a battery compartment for receiving a battery, and   a control circuit configured to control the flow of electric current between a battery received in said battery compartment and said electric heating element;   
       wherein said electric heating element, said battery compartment, and said control circuit are all located in said movable part. 
     
     
         2 . An eyelash curler according to  claim 1 , wherein said palm part and said movable part together constitute an elongated entity that is thicker towards said second end than said first end of the palm part, so that towards said second end said elongated entity constitutes a handle, a diameter of which is between 15 and 40 mm and a length of which is between 60 and 160 mm, to fit in a hand of a human user. 
     
     
         3 . An eyelash curler according to  claim 1 , wherein:
 said first curling surface is a part of a first plate, directed transversally with respect to said longitudinal direction and supported by a first support arm as a part of said palm part, and   said first support arm attaches to a middle part of said first plate, a transverse thickness of said first support arm being less than 10 mm at a location below said first plate in said longitudinal direction.   
     
     
         4 . An eyelash curler according to  claim 3 , wherein said second curling surface is a part of a second plate, directed transversally with respect to said longitudinal direction and supported by a second support arm as a part of said movable part. 
     
     
         5 . An eyelash curler according to  claim 1 , wherein towards said second end said palm part comprises a tubular section, so that said movement of the movable part with respect to said palm part in said longitudinal direction involves moving a portion of said movable part inside said tubular section. 
     
     
         6 . An eyelash curler according to  claim 1 , wherein:
 each of said first and second curling surfaces is limited on one side by a concave eyelid-side edge, and   at least said first curling surface extends for more than 8 millimetres from the respective eyelid-side edge towards a respective distal edge.   
     
     
         7 . An eyelash curler according to  claim 6 , wherein at least one of said first and second curling surfaces comprises one or more ridges or grooves directed parallel to the respective eyelid-side edge. 
     
     
         8 . An eyelash curler according to  claim 7 , wherein at least one ridge in one of the first and second curling surfaces is met by a corresponding groove in the other. 
     
     
         9 . An eyelash curler according to  claim 6 , wherein said first curling surface comprises a protruding ridge parallel to the eyelid-side edge of said first curling surface and displaced from said eyelid-side edge by less than 3 mm. 
     
     
         10 . An eyelash curler according to  claim 1 , wherein said electric heating element is located under at least one surface layer of said second curling surface. 
     
     
         11 . An eyelash curler according to  claim 1 , wherein said second curling surface comprises a piece of elastic material detachably attached to a support located at said first end of said movable part. 
     
     
         12 . An eyelash curler according to  claim 11 , wherein said support is a support box with a bottom and edges, and wherein said electric heating element is located in said support box and separated from said bottom by an array of protrusions in said bottom. 
     
     
         13 . An eyelash curler according to  claim 1 , wherein said movable part comprises a flex circuit that extends from said battery compartment to said electric heating element and carries all electric connections between discrete electric parts of the eyelash curler. 
     
     
         14 . An eyelash curler according to  claim 13 , wherein said electric heating element consists of resistors attached to that end of the flex circuit that extends to the first end of the movable part. 
     
     
         15 . An eyelash curler according to  claim 1 , wherein said movable part comprises a push pad formed of a surface oriented at least partially obliquely or transversally with respect to said longitudinal direction for enabling a human user to push said movable part in said longitudinal direction.
