Abstract

Dropper including a first element which may be associated with a container mouth, the first element including a support for an elastically deformable suction cap sealedly coupled to a pipette, a push button which slides axially in relation to the first element to compress the suction cap, a selector rotatably constrained to the first element, with one thereof—i.e. either selector or push button—being fitted with at least two grooves with different depths and with the other—i.e. either button or selector—equipped with at least one flap cooperating with grooves so, when the flap is associated with a groove, following rotation of the selector, button stroke length is limited to depth of the groove associated with the flap, to adjust the amount of a fluid suctioned and/or dispensed by the dropper, the first element and button torsionally coupled.

Dependent claims

A dropper comprising a first element configured to be associated with a container,

the first element comprising a support of an elastically deformable suction cap sealedly coupled to a pipette,
a push button axially slidable relative to the first element for compressing the suction cap,
a selector rotatably constrained to the first element, one between the selector and the push button having at least two grooves of different depth and the other between the button and the selector being provided with at least one flap cooperating with said grooves so that, when the flap is associated with a groove, following a rotation of the selector, a stroke of the button is limited to the depth of the groove to which the flap is associated, so as to adjust the volume of a fluid aspirated and/or dispensed by the dropper, the first element and the button being torsionally fixed, so that a rotation of the selector do not induce a corresponding rotation of the button.
