Liquid product e.g. cosmetic product, distribution device, has lip elastically applied against outer face to isolate passage with respect to atmosphere, and made of silicone naturally adhering with polybutylene terephthalate of support

摘要

The device has a distribution head (3) with a liquid product passage (10) opening towards an exterior and a core (14) extending within a nozzle housing. A nozzle (4) has a sealing lip (22) fitted on a rigid tubular support (18) cased in the head. The lip is elastically applied against an outer face (16) of the head for isolating the passage with respect to the atmosphere. The support is made of polybutylene terephthalate, and the lip is made of liquid silicone which naturally adheres with the polybutylene terephthalate. An independent claim is also included for a distribution nozzle of a liquid product distribution device.
