Device for dispensing a liquid or pasty product, comprising a wringer part
First Claim
1. A device for dispensing a liquid or pasty product, comprising a product reservoir having a longitudinal axis surmounted by a neck and provided with a wringer part made of a resiliently deformable material;
- anda cap to close the neck of the reservoir, the cap having a rod passing through the wringer part, one end of the rod being provided with an applicator part extending into the reservoir when the cap is in the closed position;
the wringer part being so shaped that during the extraction of the applicator part out of the reservoir, the wringer part first wipes the rod and is subsequently expanded under the pressure of the applicator part, the applicator part having a cross-section (S) measured perpendicularly to the longitudinal axis that is distinctly greater than that (s) of the rod;
wherein in the wringer part has a portion in the shape of an inner portion of a torus whose convexity is turned towards the longitudinal axis of the reservoir and with one end of the torus being free.

Abstract
A device (D) for dispensing a liquid or pasty product (P) comprises a reservoir (1) of product equipped with a neck (2), and a cap (4) to close the neck of the reservoir. The cap (4) is provided with a rod (9) carrying an applicator part (7) extending into the reservoir when the cap is in the closed position. The neck (2) of the reservoir is equipped with a wringer (5) in the shape of an hourglass (10) made of a deformable elastic material through which the applicator part (7) passes as it is drawn out of the reservoir (1). The wringer (5) being designed to wipe the rod (9) and enlarge the cross-section of its opening to allow the applicator part (7) to pass through. The cross-section (S) of this applicator part being distinctly greater than that (s) of the rod (9).
