Summary:The invention relates to a dispensing device that is intended to be mounted on a container to form a dispenser for a fluid product, the dispensing device comprising a polyester composition consisting essentially of a mixture of components A and B which are defined as follows: A: a copolyether ester elastomer (COPE) consisting essentially of hard segments of polyester and soft segments of aliphatic polyether and having a hardness of less than 50 shore D; and B: a polyethylene terephthalate (PET) or a copolyester, or a mixture of both. Dispositif de distribution destiné à être monté sur un récipient pour constituer un distributeur de produit fluide, le dispositif de distribution comprenant une composition de polyester consistant essentiellement en un mélange des composants A et B définis comme suit : A : un élastomère de copolyéther ester (COPE) constitué essentiellement de segments durs de polyester et de segments mous de polyéther aliphatique et ayant une dureté inférieure à 50 shore D, et B : un polyéthylène téréphtalate (PET) ou un co-polyester, ou un mélange des deux.
