Abstract
The invention relates to a so-called “anti-drip” cap (10) for a flexible bottle (12) including a base (16), in communication with the bottle, covered by a cover (26), including an outlet opening (30), the cover (26) being movable between a bottom blocking position and a top dispensing position, characterized in that the cover (26) is mobile between a first angular position associated with the bottom blocking position and a second angular position, in which the cover (26) is mobile under the pressure of a product feeding the base, between an intermediate position for venting the bottle (12) and the top dispensing position, an elastic return element (38) with a predetermined stiffness being inserted in the second angular position between the cover and the base.

An “anti-drip” cap (10) for a deformable bottle (12), notably a flexible bottle, containing a cosmetic, pharmaceutical, industrial or food product in liquid or cream form, including:
- a substantially tubular base (16) that is adapted to be fixed and sealed to a complementary tubular neck (14) of the bottle (12) and an “upper” transverse wall (22) of which includes at least one inlet orifice (24) communicating with the neck (14) of the bottle (12),
- a substantially tubular cover (26) that caps the base (16) in sealed manner and an “upper” transverse face wall (28) of which includes at least one product outlet orifice (30),
- the cover (26) and the base (16) defining a sealed chamber (32) through which the product passes disposed between the inlet orifice (24) of the base (16) and the product outlet orifice (30),
- said cover (26) being mobile vertically between at least:
- a low blocking and locking position in which the cover (26) is locked onto the base (16) and in which the product outlet orifice (30) is lowered over a blocking member (34) that projects coaxially from the upper transverse wall (22) of the base (16), said blocking member (34) blocking the product outlet orifice (30),
- a high dispensing position in which the outlet orifice (30) is disposed with a particular high clearance (J) above the blocking member (34) to allow the product to pass through the inlet orifice (24), the outlet orifice (30) and the chamber (32),
- characterized in that the cover (26) is mounted to be pivoted manually between:
- a first angular position in which the cover (26) is locked in the lower blocking and locking position by an upper abutment (36) integral with the base (16),
- a second angular position in which the cover (26), released from the abutment (36), is vertically mobile between at least:
- an intermediate position in which the cover (26) is disposed at a distance from the base (16) equal to a small clearance (j) to allow the product outlet orifice (30), which is disposed at a distance from the blocking member (34) equal to said small clearance (j), to vent the bottle (12),
- the high dispensing position in which the cover (26) is disposed at a distance from the base (16) equal to the particular high clearance (J) to allow the product outlet orifice (30), which is disposed at a distance from the blocking member (34) equal to said high clearance (J), to allow the product to pass through the inlet orifice (24), the outlet orifice (30) and the chamber,
- elastic means (38) of particular stiffness being disposed in the second angular position between the cover (26) and the base (16) to allow the cover (26) to be returned toward its vertical intermediate position and to allow raising of the cover (26) toward its high dispensing position as soon as product injected from the neck (14) of the bottle (12) exerts sufficient pressure on the upper wall (28) of the chamber (32) for the resulting force to overcome the force of said elastic return means (38).
