1. A wiper for a container, the wiper comprising:
- an upper part and a lower part, wherein the lower part is a sealing part;
wherein the sealing part extends from the upper part towards a distal end of the wiper, the sealing part comprises at least three sidewalls;
wherein the sealing part is capable of assuming a closed state and an open state;
wherein in the closed state, the at least three sidewalls converge towards a central longitudinal axis of the wiper such that free ends of adjacent sidewalls of the at least three sidewalls abut each other to form a Y-shaped seal at the distal end of the wiper;
wherein in the closed state, the adjacent sidewalls of the sealing part come together to define slits between the free ends of the adjacent sidewalls;
wherein all the slits meet one another at a point on the central longitudinal axis of the wiper;
wherein in an open state, the at least three sidewalls are deflected away from the central longitudinal axis of the wiper such that their free ends move apart from each other; and
wherein the at least three sidewalls are resilient and bias the sealing part towards the closed state.

Abstract
A wiper which seals the container upon withdrawal of an applicator from the container. The wiper comprises an upper part and a lower part which is a sealing part, and wherein the sealing part is a self-sealing resilient structure. In a closed state of the sealing part, the sealing part forms a seal at a distal end of the wiper and in an open state, an opening is formed at the distal end of the wiper, when the applicator is inserted into the wiper. The wiper of the present disclosure can be employed in the container used for application of cosmetic or care products include viscous cosmetics, mascara, eye liner, lip gloss, hair color and like products.
