Abstract
The present invention concerns an adaptor device for coupling a suction nozzle to a container, preferably containing chemical products, comprising:—an at least partially elastic disc (1), provided with a through hole (2), one or more tongues (4) coupled to the disc (1) and projecting from one surface of the disc (1), the disc (1) being capable to transmit a pressure exerted onto a perimeter of the through hole (2) so that a free end of each one of said one or more tongues (4) bends towards a central portion of the disc (1).
Claims9
Adaptor device for coupling a suction nozzle to a container, preferably containing chemical products, comprising:
- an at least partially elastic disc (1), provided with a through hole (2),
- one or more tongues (4) coupled to the disc (1) and projecting from one surface of the disc (1),
- the disc (1) being capable to transmit a pressure exerted onto a perimeter of the through hole (2) so that a free end of each one of said one or more tongues (4) bends towards a central portion of the disc (1).
Adaptor device according to any one of the preceding claims, characterised in that the through hole (2) of the disc (1) is delimited by an annulus subdivided into a plurality of sectors, preferably equal to each other, more preferably equal to four.
Adaptor device according to any one of the preceding claims, characterised in that said one or more tongues (4) are integrally coupled to the disc (1).
Adaptor device according to any one of the preceding claims, characterised in that it further comprises a cover (7) provided with a through hole (8).
