Abstract: The invention relates to a container such as a bottle, flask, tank or similar for housing a product to be protected from light, said container being made from a thermoplastic material and produced by blowing or by draw-blowing of a preform, characterised in that said container has a layer of thermoplastic material loaded in a homogeneous manner with mica flakes at a level of 2 to 4% by weight with the addition of titanium oxide powder at a level of 2 to 4% by weight.

Abstract: The invention concerns a barrier coating to gases deposited on a polymer substrate by low pressure plasma, characterised in that it comprises a silicon oxide barrier which is coated with a protective hydrogenated amorphous carbon film.

Abstract: The invention concerns in particular a method using a low pressure plasma for depositing a barrier coating on a substrate to be treated, wherein the plasma is obtained by partial ionisation, under the action of an electromagnetic field, of a reaction fluid injected under low pressure in a treating zone. The method is characterised in that it comprises at least a step which consists in depositing on the substrate an interface layer which is obtained by bringing to plasma state a mixture comprising at least an organosilicon compound and a nitrogenous compound, and a step which consists in depositing, on the interface layer, a barrier layer, essentially consisting of a silicon oxide of formula SiOx.

Abstract: The invention concerns in particular a method for using low pressure plasma to deposit a coating on an object to be treated, whereby the plasma is obtained by partially ionising, under the action of an electromagnetic field, a reaction fluid injected under low pressure into a treatment zone. The invention is characterised in that the method comprises at least two steps: a first step during which the reaction fluid is injected into the treatment zone at a first flow rate and under a given pressure, and a second step during which the same reaction fluid is injected into the treatment zone at a second flow rate lower than the first.

Abstract: The invention concerns a device for controlling a fluid flow, characterised in that said device comprises second valve arrangement means interposed in the circuit in series with first valve arrangement means (20, 22, 34), and wherein a second mobile closure element (38) moves between a pressing position, wherein it is pressed on the seat (32) of a second threshold (30) and an opening position wherein the second closure element (38) is spaced apart from the second seat (32) to allow the fluid through the second threshold (30), and in pressing position, the second closure element (38) allows a reduced flow of the fluid through the second threshold (30).

Abstract: A filling machine including at least one filling tube (22), whereby a product flows through said filling tube and said filling tube is placed opposite the opening of a receptacle that is to be filled. The feed for the filling tube is controlled by a valve (30) which is arranged in a downward skewed position in relation to the tube and the valve is joined to the tube by a feed pipe (28).

Abstract: A filling machine (38) includes at least one filling tube (22), whereby a product flows through the tube, which tube is placed opposite the opening of a receptacle (12) that is to be filled. The filling tube is accommodated in a fixed housing that is joined to a support (34) for the filling tube; the housing possesses an orifice (48) whereby the filling tube is placed opposite thereto and the housing also includes a moveable obturating flap (50) that closes the orifice and seals the housing when in a closed position. The machine includes structure that enables a cleaning agent to be circulated inside the housing.

Abstract: A flowback method for a product contained in the distribution circuit of a filling machine. The distribution circuit (22, 24, 26, 28, 30) creates an upstream/downstream link between a storage tank for said product and a filling tube (22) that is placed opposite the opening of a receptacle (12) that is to be filled. The method includes a step whereby a closed area around the filling tube (22) is defined by a sealed housing (38). The method further includes a step whereby a circulating liquid is injected into the above-mentioned area under pressure. The liquid passes through an auxiliary port (70), whereupon the product contained in the distribution method (22, 24, 26, 28, 30) flows back in the direction of the storage tank.
