Abstract: A synthetic resin article includes a translucent or semitranslucent external portion (10) and an internal portion (1) having on its external surface an ornament, in particular a gold or silver metallization. The external and internal portions (10 and 1) comprise complementary assembly structure (8, 14; 5, 11) and are assembled by wedging and ultrasonic welding. The internal portion (1) is formed of a thermoplastic resin selected from the group consisting of polyolefin, polyamide, PVC, polyethylene terephthalate and methylpentene resins. The external portion (10) is constituted of a translucent or semitranslucent synthetic resin. The internal portion (1) is a tubular element comprising a bottom (2) of larger transverse cross section than a tubular portion (3) of the internal portion (1) and which has a bent-back edge (4) extending along the tubular portion (3) of the tubular element creating a recess (5).

Abstract: Double dispensing receptacle with deformable walls comprising two compartments (4, 4') separated from each other and connected to a distributing head (8). The tubular body (1) of the receptacle has a substantially oval shape whose ends are formed by the two compartments (4, 4'). At least one free space (5) is provided between the compartments (4, 4'). The free space (5) deforms under the influence of manual pressure by escape of the air via an opening provided in the receptacle. The receptacle is made of an elastically deformable material, so that it resumes its original shape upon release of pressure, the outside air re-entering the free space through the opening in the receptacle. The compartments are circular in cross section and are spaced apart by the free space (5).

Abstract: A proportioning device for a double dispenser has a double receptacle and a dispensing head (1), the device having, facing outlet openings (6) for the products, openings (5) of different or equal diameters. The proportioning device has a capsule (2) screwed on the dispensing head (1), having a constriction (3) holding a disk (4) having at least one pair of openings (5) of different or equal diameters which are diametrically opposed. The capsule (2) and disk (4) are covered by a ring (8) driving the disk (4) in rotation the disk (4) by teeth on the external periphery of the disk meshing with teeth on the internal surface of the ring. Use for the distribution of liquid or pasty cosmetic products.

Abstract: A case such as a cosmetic case has a base and a lid hinged on the edge of the base. Adjacent the hinge (4) of the case (1), the base (2) has at least one flexible tongue (8) of limited elasticity. The lid (3) has, facing that tongue (8), at least one rigid protuberance (6), such that during closure of the case (1), the protuberance (6) of the lid (3) will come into abutment against the flexible tongue (8) of the base (2). The limited elasticity of the flexible tongue (8) ensures that closure of the lid on the base will be stopped whilst not yet complete, thereby to leave a small gap between the lid and the base into which the fingernail can be inserted to reopen the case.

Abstract: A double dispenser for fluid products, comprising, in a single casing (1), two chambers (2) filled with different fluids and each closed by a pump (3) provided with a valve, the two valves being actuated by a single pusher (5). The pusher (5) has a chamber into which open the outlets of the two valves. This chamber is divided by a wall (7) so as to form two separate chambers (6', 6") into which open respectively the outputs of the two valves. The wall (7) has two outlet openings (8', 8") respectively connected to the separate chambers (6', 6"). These outlet openings (8', 8") open into cavities (10', 10") of a dispensing nose (11) of elastically deformable material. The dispensing nose (11) has an outlet slot (12) sealingly closed by two lips (13) arranged to spread under the pressure of the mixed fluid arriving respectively in the cavities (10', 10") during depression of the pusher (5). The dispensing nose (11) comprises an intermediate partition (14) separating the cavities (10', 10").

Abstract: A dispenser for a liquid or pasty product, comprising a casing (1) containing at least one reservoir of product to be dispensed, a pump associated with the reservoir and actuated by a pusher (3) and a dispensing nose (2) of thermoplastic material on the pusher (5) and adapted to receive the product from an outlet of the pump. The nose (2) comprises two sealing lips (4) arranged to spread elastically under the pressure of the product. The nose (2) is molded of one piece with a tongue (5) to which the nose is connected by at least one thin tab (6). The tongue (5) is disposed between the nose (2) and the casing (1) in such a way as to block the pusher until such time as the tongue (5) is torn from the nose (2) by severing the thin tab or tabs (6).

Abstract: A dispensing packing for stick-shaped pasty products which is made from synthetic material and includes a hollow body inside of which the pasty stick is guided in the longitudinal direction, a device for displacing the stick formed of a sliding piston to which the stick is connected and of a screw for displacing the piston, a drive cap for rotating the screw mounted at one end of the body opposite to the closure cap of this body. The body has on the one hand an internal jacket defining both longitudinal ends of the body and made from a resiliently deformable material compatible with the pasty product as well as an external case partially surrounding the jacket and assembled to the latter. The packing is intended for the conditioning of sanitary or cosmetic products such as deodorants or lipsticks.

Abstract: A gas/liquid heat exchanger is provided which comprises means for circulating gas and/or liquid and a plurality of hollow fibres, adapted to receive said gas or said liquid, said fibres being of polymeric material which is inert with respect to said liquid and are permeable to said liquid. Such a heat exchanger considerably improves the efficiency/volume ratio of the appratus, largely as a result of the liquid which permeates through the fibres vaporizing.
