An “anti-drip” cap for a deformable bottle including a base, connecting with the bottle, covered by a cover, including an outlet opening, the cap being movable between a sealing and locking configuration corresponding to a first angular position and a low vertical position of the cover, an intermediate configuration for venting the cap by an escape element corresponding to a second angular position and the low vertical position of the cover, and a dispensing configuration of the cap corresponding to the second angular position and a high vertical position of the cover in which the outlet opening is released, the cap passing from the intermediate configuration to the dispensing configuration once the cover is moved by the pressure of a product supplying the base, and returning to the intermediate configuration when the cover is returned under the effect of an elastic return element interposed between the cover and the base. |

1. An anti-drip cap for a deformable bottle (12) containing a cosmetic, pharmaceutical, industrial or food product in liquid or cream form, including:
a substantially tubular base (16), which is intended to be fixed on a complementary tubular neck (14) of the bottle (12), and an inlet transverse wall (22) of which that seals the neck (14) of the bottle (12) which includes at least one inlet opening (24) connecting with the inside of the bottle (12), a substantially tubular cover (26), which covers the base (16), and an upper transverse wall (28) of which includes at least one product outlet opening (30),the cover (26) and the base (16) defining an impermeable passage chamber (32) for the passage of the product, interposed between the inlet opening (24) of the base (16) and the outlet opening (30) for the product,said cap being likely to occupy at least:
a sealing and locking, first configuration, associated with a first angular end position of the cover and with a first low axial position of said cover (26) with respect to the base (16), in which the cover (26) is immobilized on the base (16) and in which the product outlet opening (30) is lowered onto a sealing element (34) which projects coaxially with the base (16) from the inlet transverse wall (22), an end bearing area (36) of the sealing element (34) sealing the product outlet opening (30), a dispensing, second configuration, associated with a second angular end position of the cover (26) and with a second high axial position of said cover (26) with respect to the base (16) in which the outlet opening (30) is placed with a high clearance (J) above the sealing element (34) in order to allow the product to pass through the inlet and outlet openings (24) and (30) and the passage chamber (32), once product is ejected from the deformable bottle (12),passing through a venting, third intermediate configuration in which the relative positions of the cover (26) and of the base (16) an escape path (38) with small dimensions connecting the passage chamber (32) with the outside in order to ventilate the deformable bottle (12), in particular, allowing the deformable bottle (12) to regain shape after having been deformed,wherein the venting, third intermediate configuration, is associated with the second angular end position of the cover (26) and with the first low axial position of said cover (26) with respect to the base (16), and in that, in the second angular position of the cover, a defined-stiffness elastic return means (40) is interposed between the cover (26) and the base (16) in order to allow the cap (10) to pass from the third to the second configuration, the cover (26) raising towards the dispensing high position once an injection of product coming from the neck (14) of the bottle (12) exerts on the upper wall (28) of the passage chamber (32) a pressure that is sufficient for the resulting force to exceed the force of said elastic return means (40), and the automatic return of the cap from the third to the second configuration, the cover (26) being returned towards the low vertical position on the base (16) once the pressure of the product is released. |
