The invention relates to a tube head equipped with an internal lining having a barrier effect, the internal lining consists of a multi-layered polymeric element fixed by an external surface layer of the element to a plastics annular covering of the head, the element also has one or more polymeric layers having a barrier effect and a total thickness of between 0.008 and 0.05 mm and an internal surface layer of polyolefin or of polyester. The invention also relates to such thermoformed monobloc becoming the internal lining element. The invention is suitable for the production of numerous tubes.

The invention relates to a strip or portion of a strip for deep drawing or drawing and ironing comprising a metallic layer carrying on one surface a surface coating of plastics material and on its other surface a coat of varnish characterized in that: the metallic layer is of aluminum alloy with each surface having a coating of anodic or chemical conversion oxide 20 to 80 nm thick; and the coat of varnish contains a solid lubricant consisting of particles which are harder than the varnish and less hard than the shaping tool or tools, which particles are of an average diameter greater than the thickness of the said coat after firing. The invention also has an object the use of this strip to produce various hollow bodies or containers, particularly with a height:diameter ratio in excess of 2.5 and for producing aerosol or pump distributors. Thus transformed, the strip according to the invention can be applied to various fields such as those of cleaning products, hygiene, foodstuffs, cosmetics and pharmaceuticals.

Aluminum-based composite and containers produced therefrom

A distributor for pasty products comprises a body having a tubular body (4) with a cylindrical barrel (5), a piston (7) with a flexible flared-out top lip (8) sliding in the barrel (5) and a top carrying an orifice through which the pasty product can pass, and also having a distribution head fixed on the tip. Pasty product is directed and expelled by a suction and compression effect. According to the invention, in order to allow air to be evacuated when the piston is being inserted into the tubular body (4), this body (4) comprises a transverse inner relief (35) having a minimal inside diameter which is 0.5 to 1.5 mm less than the inside diameter of the barrel (5) and, preceding it, a flared-out inlet zone (36) having an engagement diameter at least equal to the outside diameter of the flexible lip (8), the outside diameter of the middle part (40) of the piston (7) being at least 0.4 mm smaller than the minimal inside diameter of the relief (35).

In a dispenser, a tubular body carrying on its top a suction valve for suction of a pasty produce into a compression chamber, a distribution head between the chamber and a distribution pipe, a central orifice in the top surrounded by a bearing surface forming the seat of the suction valve, an actuator including the distribution pipe and a duct fitting the top of a deformable cap which defines the compression chamber; the deformable cap including a deformable web and an upper tube carrying a flexible lip forming a valve with the bottom of the duct for expelling the product into pipe.

Dispenser for pasty product

A closure device for both smooth necked and threaded necked containers includes a tamperproof cap frangibly affixed to the container for selective removal by manipulation of the cover. Upon breaking the tamperproof seal by cover manipulation, the cap may be retained within the cover to avoid disposal problems and to serve as a sealing component when the container is resealed after initial opening occurs.
