Manual strip applicator, in particular a corrector

Abstract

A manual strip applicator that includes a grippable casing; a mobile application head which moves in relation to the casing and which projects from the casing when in the use configuration; a supporting strip bearing a material to be applied to a substrate; a strip-moving device arranged in the casing and designed to move over the application head; where the applicator additionally includes a return device connected to the casing and to the application head, the return device includes at least a first magnetic member (A) and a second magnetic member (M), the first and second magnetic members being arranged in the use configuration to be substantially facing one another and to generate magnetic field lines in opposite directions, the return device being adapted to allow, in the use configuration, a displacement of the application head between a proximal position and a distal position relative to the casing; and exert, in the use configuration, a return force urging the application head towards the distal position.

         16 . A manual strip applicator, comprising:
 a grippable casing;   a mobile application head which moves in relation to the casing and which projects from the casing when in the use configuration;   a supporting strip bearing a material to be applied to a substrate;   a strip-moving device arranged in the casing and designed to move the strip over the application head; and   a return device connected to the casing and to the application head, the return device comprising at least a first magnetic member and a second magnetic member, the first and second magnetic members being arranged in the use configuration to be substantially facing one another and to generate magnetic field lines in opposite directions,   wherein the return device is adapted to allow, in the use configuration, a displacement of the application head between a proximal position and a distal position relative to the casing; and   exert, in the use configuration, a return force urging the application head towards the distal position.   
     
     
         17 . The applicator according to  claim 16 , wherein the second magnetic member is integrally attached to the strip-moving device and is designed to generate field lines that are substantially parallel to a direction of displacement of the application head in the use configuration. 
     
     
         18 . The applicator according to  claim 17 , wherein the casing has members for guiding a translational motion of the strip-moving device, which are designed so that in the proximal position of the application head, the second magnetic member comes nearly in contact with the first magnetic member. 
     
     
         19 . The applicator according to  claim 17 , wherein the first magnetic member is connected to a manual activating member designed to control a rotation of the first magnetic member between a first position in which the applicator is in the use configuration and a second position in which the applicator is in a retracted configuration of the application head. 
     
     
         20 . The applicator according to  claim 19 , wherein the first magnetic member and the second magnetic member each have a substantially flat side facing each other in the use and retracted configurations. 
     
     
         21 . The applicator according to  claim 20 , wherein the first magnetic member has two opposite ends each defining a monopole face, and the rotation of the first magnetic member occurs around an axis perpendicular to the direction of the displacement of the application head. 
     
     
         22 . The applicator according to  claim 20 , wherein the second magnetic member has a substantially flat side, which is at least dipolar, facing the first magnetic member, and the first magnetic member has an axis of rotation parallel to the direction of displacement of the application head. 
     
     
         23 . The applicator according to  claim 16 , wherein the application head and the strip-moving device are integrally attached and are guided in translational motion by guiding members of the casing, the first magnetic member being fixed to the casing and the second member being fixed to the strip-moving device. 
     
     
         24 . The applicator according to  claim 19 , comprising a member for adjusting the position of the first magnetic member in the use configuration along the direction of displacement of the application head. 
     
     
         25 . The applicator according to  claim 17 , wherein the amplitude of the displacement of the application head between the distal position and the proximal position is between 2 and 10 mm. 
     
     
         26 . The applicator according to  claim 16 , wherein the return force towards the distal position of the application head is between 0.5 and 12 Newtons, between the distal position and the proximal position, and increases very significantly as the proximal position is approached. 
     
     
         27 . A manual strip applicator, comprising:
 a grippable casing;   a mobile application head which moves in relation to the casing and which projects from the casing when in the use configuration;   a supporting strip bearing a material to be applied to a substrate;   a strip-moving device arranged in the casing and designed to move the strip over the application head; and   a magnetic device comprising a first magnetic member connected to the casing and a second magnetic member connected to the application head, the magnetic device being designed to activate a displacement of the application head from a position within the casing which corresponds to a retracted configuration to a protruding position which corresponds to the use configuration.   
     
     
         28 . The applicator according to  claim 27 , wherein the magnetic device comprises a manual activating member with two adjustment settings, the first magnetic member being connected to the manual activating member, and the second magnetic member being integrally attached to the strip-moving device.
