A device for fixing a dispenser member such as a pump on the neck of a receptacle containing a substance to be dispensed, the device being characterized in that it has a single fixing element made of a deformable material and disposed in the neck of the receptacle between the inside surface of the receptacle neck and the outside surface of the body of the dispenser member, the fixing element being, in the assembled state of the fixing device, deformed and/or compressed by the body of the dispenser member being engaged in the neck of the receptacle in such a manner that it exerts a radial force on the body of the dispenser member and on the neck of the receptacle, the radial force providing reliable and leakproof fixing of the dispenser member to the neck of the receptacle.
A combination of components comprising (1) a receptacle containing a substance to be dispersed and having a neck with an inside surface (2) a dispenser member having a body defining an outside surface, and (3) a fixing element wherein the dispenser member is fixed on the neck of the receptacle said fixing element being disposed in the neck of the receptacle between the inside surface of said receptacle neck and the outside surface of the body of the dispenser member, said fixing element being, in the assembled state of the combination of components, deformed and/or compressed by the engagement of the body of the dispenser member in the neck of the receptacle in such a manner that the fixing element exerts a radial force on said body of the dispenser member and on said neck of the receptacle, said fixing element being a single fixing element made of a deformable flexible material, said radial force providing reliable and leakproof fixing of the dispenser member to the neck of the receptacle, said fixing element having a bottom end and holding means at said bottom end for fixing said fixing element beneath said receptacle neck inside the receptacle after the dispenser member has been engaged.
A combination of components comprising (1) a receptacle containing a substance to be dispensed and having a neck with an inside surface, (2) a dispenser member having a body defining an outside surface, and (3) a fixing element wherein the dispenser member is fixed on said receptacle neck, said fixing element being disposed in said receptacle neck between said inside surface of said receptacle neck and said outside surface of said dispenser member body, said fixing element being, in the assembled state of the combination of components, deformed and/or compressed by the engagement of said dispenser member body in said receptacle neck in such a manner that said fixing element exerts a radial force on said dispenser member body and on said receptacle neck, said fixing element being a single fixing element made of a deformable flexible material, said radial force providing reliable and leakproof fixing of said dispenser member to said receptacle neck, said fixing element having a bottom end and holding means at said bottom end for fixing said fixing element beneath said receptacle neck inside said receptacle after said dispenser member has been engaged, and said holding means being made in the form of tabs, each tab having a swelling of deformable material at its bottom end.
A combination of components comprising (1) a receptacle containing a substance to be dispensed and having a neck with an inside surface, (2) a dispenser member having a body defining an outside surface, and (3) a fixing element wherein the dispenser member is fixed on said receptacle neck, said fixing element being disposed in said receptacle neck between said inside surface of said receptacle neck and said outside surface of said body of said dispenser member, said fixing element being, in the assembled state of the combination of components, deformed and/or compressed by the engagement of said dispenser member body in said receptacle neck in such a manner that said fixing element exerts a radial force on said dispenser member body and on said receptacle neck, said fixing element being a single fixing element made of a deformable flexible material, said radial force providing reliable and leakproof fixing of said dispenser member to said receptacle neck, said fixing element having a bottom end and holding means at said bottom end for fixing said fixing element beneath said receptacle neck inside said receptacle after said dispenser member has been engaged, said holding means comprising one or more swellings of material which, prior to said dispenser member being engaged, project towards the inside of said fixing element and which, during engagement of said dispenser member, are forced under said reciptacle neck by the body of said dispenser member, and said body of the dispenser member having an external groove which, in the assembled state of the components after the dispenser member has been engaged, is situated level with said holding means, a portion of said holding means being received in said groove to fix the dispenser member relative to said fixing element.
