Lockable dispensing head
A dispensing head which can be mounted on a receptacle. The dispensing head includes a pump, for surmounting the receptacle, with an actuating rod having a longitudinal axis X. A diffuser is mounted on the pump, and includes a tube opening at a dispensing orifice, with the tube being elongated along an axis Y distinct from the axis X. A lever arm controls the actuation of the pump, with the lever arm including a portion capable of coming to bear on the diffuser in order to actuate the pump. In addition, a locking member is configured such that, in a first position, the locking member allows actuation of the pump and, in a second position, the locking member prevents actuation of the pump. In a disclosed example, in the second position the tube abuts against a portion of the locking member to prevent actuation of the pump.
1. A dispensing head for a receptacle, the dispensing head comprising:
a substantially cylindrical mounting band configured for attachment to the receptacle;
a substantially cylindrical locking member arranged within the mounting band;
a pump arranged within the mounting band, the pump comprising an actuating rod arranged along a vertical axis X;
a substantially cylindrical diffuser mounted on the pump and arranged within the locking member, the diffuser comprising a tube that extends horizontally away from a remainder of the diffuser and opens at a dispensing orifice; and
a lever arm having a first end and a second end, the first end being hingedly mounted to the mounting band;
wherein:
a portion of the lever arm between the first end and the second end bears down on the diffuser and actuates the pump when a user applies pressure to the second end of the lever arm;
the locking member is provided in the dispensing head so as to be rotatable within the mounting band and about the diffuser;
the locking member has an upper edge including a recessed portion that is lower than adjacent portions of the upper edge;
an uppermost portion of the upper edge of the locking member is situated below the tube of the diffuser when the diffuser is not being pressed to actuate the pump;
when the locking member is rotated so that the recessed portion of the upper edge is situated below the tube of the diffuser, the diffuser may freely move up and down to actuate the pump; and
when the locking member is rotated so that the recessed portion of the upper edge is not situated below the tube of the diffuser and the user applies pressure to the second end of the lever arm, a bottom surface of the tube abuts the upper edge so that the diffuser may not freely move up and down to actuate the pump.
2. The dispensing head according to claim 1 , wherein the locking member comprises at least one tab extending radially outwardly from a remainder of the locking member.
3. The dispensing head according to claim 2 , wherein the locking member comprises two diametrically opposed tabs extending radially outwardly from a remainder of the locking member.
4. The dispensing head according to claim 2 , wherein:
the mounting band includes a recess that receives the at least one tab of the locking member;
the at least one tab abuts against a first side of the recess when the locking member is rotated so that the recessed portion of the upper edge is situated below the tube of the diffuser; and
the at least one tab abuts against a second side of the recess when the locking member is rotated so that the recessed portion of the upper edge is not situated below the tube of the diffuser.
5. The dispensing head according to claim 4 , wherein the locking member comprises two radially extending tabs that are respectively received in two recesses provided on the mounting band.
6. The dispensing head according to claim 1 , wherein the lever arm comprises a window traversed by the tube.
7. The dispensing head according to claim 1 , wherein the pump is mounted onto the mounting band.
8. The dispensing head according to claim 1 , wherein the lever arm includes a first descending portion descending downwardly toward the first end and a second descending portion descending downwardly toward the second end.
9. A device, comprising a receptacle and the dispensing head according to claim 1 .
10. The device according to claim 9 , further comprising a cosmetic product provided in the receptacle.
11. The device according to claim 10 , wherein the cosmetic product comprises a cream, a foam, a gel or a spray.
