Laterally-actuated fluid product dispensing device

A fluid dispenser device comprising:

• a body, a reservoir;
• a dispenser head incorporating a dispenser orifice;
• and
• a dispenser member that is mounted on said reservoir by means of a fastener ring, said dispenser member comprising a dispenser-member body and a movable member that moves axially in said dispenser-member body while said dispenser member is being actuated;
• said device further comprising a lateral actuator system that is secured to said body, said system including an actuator element that is movable, substantially transversally to the direction of movement of said movable member, between a rest position in which said dispenser member is not actuated, and an actuated position in which said dispenser member is actuated;
• said body including at least two axial guide surfaces for guiding said actuator element during an actuation stroke, said at least two axial guide surfaces being straight and stationary relative to said dispenser head and parallel to a movement axis of the movable member in the dispenser-member body while said dispenser member is being actuated;
• said actuator element including an end edge that co-operates with said at least two axial guide surfaces;
• said device further comprising an intervening profile or shoulder between said at least two axial guide surfaces that modifies the co-operation between said end edge of said actuator element and said at least two axial guide surfaces, such that, in order to be passed over, said profile or shoulder requires the user to act on said lateral actuator system with an actuation force that is higher than an actuation force required without the profile or shoulder;
• and
• wherein said end edge of said actuator element that co-operates with said at least one axial guide surface is a convex rounded surface that defines a distal end shape of the actuator element.

A fluid dispenser device comprising:

• a body;
• a reservoir;
• a dispenser head incorporating a dispenser orifice;
• a dispenser member mounted on the reservoir by a fastener ring, the dispenser member comprises a dispenser-member body and a movable member that moves axially in the dispenser-member body while the dispenser member is actuated;
• and
• a lateral actuator system secured to the body, the lateral actuator system comprising an actuator element movable, substantially transversally to the direction of movement of the movable member, between a rest position in which the dispenser member is not actuated, and an actuated position in which the dispenser member is actuated;
• the body comprises an axial guide surface that guides the actuator element during an actuation stroke in sliding movement, the axial guide surface is straight and stationary relative to the dispenser head and substantially parallel to a movement axis of the movable member in the dispenser-member body while the dispenser member is being actuated;
• the actuator element comprises an end edge that co-operates with the axial guide surface;
• the fluid dispenser further comprising a profile immediately followed by the axial guide surface, the profile projects away from the axial guide surface and towards the actuator element so as to engage the end edge of the actuator element, such that, in order for the profile to be passed over by the actuator element, an actuation force on said lateral actuator system is required that is higher than an actuation force that otherwise would be required without the profile;
• and
• wherein said end edge of said actuator element that co-operates with said axial guide surface is a convex rounded surface that defines a distal end shape of the actuator element.

A fluid dispenser device comprising:

• a body, a reservoir;
• a dispenser head incorporating a dispenser orifice;
• and
• a dispenser member that is mounted on said reservoir by means of a fastener ring, said dispenser member comprising a dispenser-member body and a movable member that moves axially in said dispenser-member body while said dispenser member is being actuated;
• said device further comprising a lateral actuator system that is secured to said body, said system including an actuator element that is movable, substantially transversally to the direction of movement of said movable member, between a rest position in which said dispenser member is not actuated, and an actuated position in which said dispenser member is actuated;
• said body including at least one axial guide surface for guiding said actuator element during an actuation stroke, said at least one axial guide surface being straight and stationary relative to said dispenser head and parallel to a movement axis of the movable member in the dispenser-member body while said dispenser member is being actuated;
• said actuator element including an end edge that co-operates with said at least one axial guide surface, wherein said at least one axial guide surface includes a portion having resistance means, wherein said resistance means comprises a modification to the portion of the at least one axial guide surface, the modification to the portion locally modifying friction between the end edge of the actuator element and the at least one axial guide surface, such that, in order to be passed over, said portion having resistance means requires the user to act on said lateral actuator system with an actuation force that is higher than an actuation force required without the resistance means;
• wherein all of the at least one axial guide surface is on or along the same axis;
• and
• wherein the modification to the portion of the at least one axial guide surface is positioned to come into contact with the end edge of the actuator element after a first predetermined portion of the actuation stroke.
