1. A wiper device for containers of cosmetic products, comprising:
- a wiper element (10) to be mounted in a casing (2) of a container (1) of cosmetic products, and designed to come into contact with an applicator (6) of cosmetic products housed in the casing (2), at least during pulling out of said applicator (6) from the casing (2);
at least one seal (12) connected to the wiper element (10), said at least one seal (12) being adapted for installation close to an opening (3) of the casing (2) and being susceptible of abutment against a closing cap (4) of the container (1);
a main tubular body (13) to be engaged in the opening (3) of the casing (2) and having a first edge (14) carrying said at least one seal (12),said at least one seal (12) and the wiper element (10) being made of a material having a lower stiffness than that of the main tubular body (13);
wherein the wiper element (10) has a substantially frustoconical and annular shape,wherein the wiper element (10) is installed on a second edge (24) of the main tubular body (13),wherein the second edge is opposite to the first edge.

Abstract
A wiper device for containers of cosmetic products comprises a wiper element (10) to be mounted in a casing (2) of a container (1) for cosmetic products and designed to come into contact with an applicator (6) housed in the casing (2), at least during pulling out of the applicator (6) from the casing (2). The wiper device further comprises means (11) for engagement of the wiper element (10) with the casing (2) and at least one seal (12) to be installed close to an opening (3) of the casing (2) and adapted for abutment against a closing cap (4) of the container (1), to ensure hermetic tightness of the container (1) and avoid escape of the cosmetic product.

11. A process for manufacturing a wiper device for cosmetic product containers, wherein said process comprises the following steps:
-
moving two moulding dies (30) close to each other, said dies delimiting a duct (31) having a first opening (32) and a second opening (33) opposite to the first one (32) and internally having a shape matching the outer shape of a main tubular body (13); inserting a first core (34) into the first opening (32); inserting a second core (35) into the second opening (33) and make the second core (35) abut against the first core (34);
said first (34) and second (35) cores and duct (31) delimiting a first inner annular volume (37) having the shape of a main tubular body (13) of a wiper device;introducing a first material in a fluid state into the first inner volume (37), waiting for solidification and formation of the main tubular body (13); removing the first (34) and second (35) cores; inserting a third core (40) into the first opening (32); inserting a fourth core (41) into the second opening (33) and make the fourth core (41) abut against the third core (40);
said third (40) and fourth (41) cores, duct (31) and main tubular body (13) delimiting a second inner volume (43) located close to a first edge (14) of the main tubular body (13) and a third inner volume (44) located close to a second edge (24) of the main tubular body (13);introducing a second material in a fluid state into the second and third inner volumes (43, 44), waiting for solidification and formation of a seal (12) in the second inner volume (43) and of a wiper element (10) in the third inner volume (44), said seal and wiper element together with said main tubular body (13) forming a wiper device (9); removing the third (40) and fourth (41) cores; and pulling the wiper device (9) out of the moulding dies (30). - View Dependent Claims (12)
