BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a fluid dispenser provided with a dual-purpose safety device, and in particular a fluid dispenser having a safety device providing safety both in transport and in first-use.
The term "transport safety" is used to refer to a device which prevents untimely or accidental actuation of the dispenser, particularly while it is being transported. The term "first-use safety" is used to refer to a device which informs the user whether the fluid dispenser has already been used for the first time.
Transport safety devices for fluid dispensers are well known in the state of the art. In particular, U.S. Pat. Nos. 3,148,806 and 3,402,862 disclose transport safety devices in which actuation of the dispenser is prevented by pivoting a portion of the pushbutton into a locking position, and to actuate the dispenser, it is necessary for said pushbutton to be pivoted back into its unlocking position. In the locking position, a portion of the pushbutton bears against a fixed element of the dispenser, thereby preventing any actuation of said pushbutton. When the pushbutton is moved into its unlocking position, it no longer co-operates with said fixed element of the dispenser and the pushbutton can be actuated to dispense the fluid.
First-use safety devices, also referred to as "guarantee", devices, are also known in the state of the art. For example, document FR-2 697 505 discloses the use of an external ring placed around the actuator member of the dispenser, said ring including a tongue that must be torn off before first use of the dispenser, with the external ring being removable once the tongue has been torn off, thereby enabling the dispenser to be actuated.
Those two distinct devices nevertheless give rise to complication in the manufacture and the assembly of dispensers, and they therefore increase cost.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a fluid dispenser having a safety device both for transport and for first use. With known dispensers, combining both kinds of safety measures implies using two distinct safety devices, one providing transport safety and the other first-use safety. Manufacture and assembly of such a dispenser is consequently more complicated, thus implying a higher cost.
An object of the present invention is to overcome the drawback and to provide a fluid dispenser which advantageously combines both types of safety measures in a single device, so as to simplify manufacture and assembly and thus reduce cost.
The present invention thus provides a fluid dispenser comprising a receptacle, a dispenser member, and an actuator member for actuating the dispenser member to dispense said fluid selectively, said actuator member being movable between a rest position and an actuation position for actuating the dispenser member, and including a body portion and a fluid expulsion portion provided with an outlet orifice, said fluid expulsion portion being movable relative to said body portion between a locking position in which it prevents the actuator member moving towards its actuation position, and an in-use position in which it allows the actuator member to move towards its actuation position, said fluid expulsion portion including a tongue which, in the locking position, co-operates with a fixing element that is fixed relative to the receptacle, co-operation taking place through a slot formed in said body portion, said slot including, before first use of the dispenser, at least one bridge of material acting as a first-use safety device and adapted to break when said fluid expulsion portion is moved for the first time from its locking position to its in-use position.
Preferably, the fluid expulsion portion is movable relative to said body portion in rotation about an axis perpendicular to the direction in which said actuator member is movable, said fluid expulsion portion in its locking position extending substantially parallel to said direction in which the actuator member is movable, and in its in-use position ex
