Cosmetic material container

Abstract

A cosmetic material container constituted by a main body and a lid member is configured such that one of a pair of abutment surfaces that abut each other when fitted is a cam surface and the other is a follower surface. The cam surface and the follower surface are configured to relatively move the main body and the lid member in a direction of a rotational axis in response to rotation of the lid member with respect to the main body. The main body and the lid member move between a fitted position at which the abutment surfaces abut each other and are held together by magnetic force, and a separated position at which the abutment surfaces are separated from each other against the magnetic force, by rotation of the lid member with respect to the main body.

1 . A cosmetic material container, comprising:
 a main body that houses a cosmetic material;   a lid member which is fitted onto the main body in a relatively rotatable manner; and   at least one set of magnets that maintain a fitted state between the main body and the lid member;   the main body and the lid member respectively having abutment surfaces that abut each other during a fitting operation;   the abutment surfaces being configured to separate and approach each other between a position at which the main body and the lid member are positioned at a predetermined position in a rotational direction of the lid member such that the abutment surfaces abut each other, and a position other than the predetermined position at which the main body and the lid member are separated in a direction of a rotational axis;   the lid member being movable between a fitted position at which the abutment surfaces abut each other and the main body and the lid member are maintained in a fitted state by magnetic force, and a separated position at which the abutment surfaces are in the position other than the predetermined position, separated from each other against the magnetic force, by rotating the lid member.   
     
     
         2 . A cosmetic material container, comprising:
 a main body that houses a cosmetic material;   a lid member which is fitted onto the main body in a relatively rotatable manner; and   at least one set of magnets that maintain a fitted state between the main body and the lid member;   the main body and the lid member respectively having abutment surfaces that abut each other during a fitting operation;   one of the abutment surfaces including a cam surface, and the other of the abutment surfaces including a follower surface that follows along the cam surface;   the cam surface and the follower surface being configured to move the main body and the lid member in a direction of a rotational axis in response to relative rotation of the lid member with respect to the main body; and   the lid member being movable between a fitted position at which the abutment surfaces abut each other and the main body and the lid member are maintained in a fitted state by magnetic force, and a separated position at which the abutment surfaces are separated from each other against the magnetic force, by rotating the lid member.

         6 . A cosmetic material container as defined in  claim 1 , wherein:
 an outer peripheral surface of the lid member and an outer peripheral surface of the main body are coplanar in the fitted state.   
     
     
         7 . A cosmetic material container as defined in  claim 1 , wherein:
 the cross sectional shapes of the main body and the lid member perpendicular to the direction of the rotational axis are linearly symmetrical with respect to one line.   
     
     
         8 . A cosmetic material container as defined in  claim 1 , further comprising:
 a plurality of the sets of magnets.   
     
     
         9 . A cosmetic material container as defined in  claim 1 , wherein:
 one of the sets of magnets is provided at one of the abutment surfaces, and the other of the sets of magnets is provided at the other of the abutment surfaces.   
     
     
         10 . A cosmetic material container as defined in  claim 9 , wherein:
 the one of the sets of magnets at one of the abutment surfaces has an N pole facing the other abutment surface, and the other of the sets of magnets at the other of the abutment surfaces has an S pole facing the one of the abutment surfaces.   
     
     
         11 . A cosmetic material container as defined in claim  1 , wherein:
 magnetic force that leaks from the set of magnets in the fitted state is being 500 gauss or less.   
     
     
         12 . A cosmetic material container, comprising:
 a main body that houses a cosmetic material;   a lid member which is fitted onto the main body; and   at least one set of magnets that maintain a fitted state between the main body and the lid member;   the main body and the lid member respectively having abutment surfaces that abut each other during a fitting operation; and   one of the abutment surfaces including a cam surface, and the other of the abutment surfaces including a follower surface that follows along the cam surface.   
     
     
         13 . A cosmetic material container as defined in  claim 2 , wherein:
