The invention concerns a double dispensing container (200) comprising an outer container (210) and an inner container (220), each container including a body (211; 221) and a head (212; 222) provided with a neck (213; 223) and a shoulder (214; 224) linking said neck to said body, said neck having a side wall and one or more dispensing orifices, the neck (223) of the inner container being housed inside the neck (213) of the outer container and having a section such that it provides one of more outflow passages for the pasty product A and, in combination with the inner surface of the outer container neck, one or more outflow passages for the pasty product B emerging onto a single or multiple orifice dispensing the product B. The invention is characterized in that said inner neck is extended by a summit portion (226) which is linked to said inner neck via a thin annular zone (227) and which closes the single or multiple orifice dispensing product A.

The invention concerns a method for making flexible tube skirts comprising a step of making a cylindrical sleeve from a planar web including several plastic or metallic layers followed by a step whereby said cylindrical sleeve is cut out to the desired length to obtain said skirts. It comprises a step prior to the step of making the cylindrical sleeve, wherein the web is subjected to a plastic deformation resulting in its being thinned by at least 0.5 % or in producing a raised surface whereof the amplitude ranges at least between 1/30 and 5 times the thickness. The web is for instance passed through the air gap between two substantially parallel rolls. Typically, the rolls exert on the web a force ranging between 2.5 and 500 newtons per millimeter of web width.

The invention relates to a method for the compression moulding of plastic parts (1) comprising a neck (3) which is equipped with an orifice. The inventive method comprises a first step involving the creation of a blank (20) and a second step involving the compression of said blank. The part is moulded with a neck (3) which is equipped with a top wall (4) comprising: a thin area with a notch (5), the contour of said thin area defining the orifice; and two zones which can withstand the mechanical stress (F) necessary in order to break the top wall (4) at the notch (5). One of said two zones (7) is intended to transmit the aforementioned mechanical stress and the other (8) is used as a support. The section of the notch (5) is slightly inclined in relation to the axis of the neck. According to the invention, after moulding, the mechanical stress (F) is applied to one part of the top wall (91), said part being different to the above-mentioned thin area (6), so that the top wall tears at the notch (5), thereby producing the dispensing orifice.

A method for decorating the cylindrical walls of receptacles, comprising the following steps: a) moveable mandrels are arranged in a loop and are displaced, keeping their axis parallel to a direction D; b) each receptacle is engaged by the cylindrical wall thereof on the mandrel; c) the mandrel is brought into the vicinity of a marking cylinder which turns about a fixed axis parallel to direction D; d) the mandrel is rotated at a speed which is correlated with that of the marking cylinder; e) a transfer film support strip is displaced between the marking cylinder and the mandrel; f) the marking cylinder and mandrel are placed in contact with each other such that the marked area of the transfer film adheres to the cylindrical wall; g) the support strip is removed from the cylindrical wall of the receptacle. The inventive method is adapted to the manufacture of flexible tubes and can be easily implemented on existing devices such as capping machines.

Tube souple (210) ayant une tête de distribution (230) et une jupe cylindrique (220) en matière plastique ou métalloplastique, de diamètre supérieur à 40 mm, caractérisé en ce que ladite jupe cylindrique a une épaisseur inférieure à 0,40 mm, en ce qu'elle comprend au moins 70% en poids, de polyéthylène haute densité (PE.HD), de masse spécifique comprise entre 0,935 g/cm3 et 0,97 g/cm3, et en ce qu'elle comprend au plus 30% en poids, de polyéthylène basse densité (PE.BD), de masse spécifique comprise entre 0,86 g/cm3 et 0,93 g/cm3, et dont plus de 50% est un PE.BD linéaire. Capsule-service (240) exempte de nervures radiales, possédant une jupe de fixation (246) plus épaisse que le reste de la paroi de la capsule-service et une coiffe ayant, au regard de la partie supérieure de la prise de doigt, une paroi inclinée vers l'intérieur de la base de la capsule, avec un angle d'inclinaison inférieur à 35°. L'ensemble tube et capsule-service fournit un conditionnement particulièrement léger parfaitement machinable en grandes cadences.

The invention also concerns a convenience closure (240) free of radial ribs comprising a fixing skirt (246) thicker than the rest of the wall of the convenience closure and a cap having, opposite the upper part of the finger hold, a wall sloping inward of the closure base, at an angle of inclination less than 35°. The tube and convenience closure assembly provides a particularly lightweight conditioning perfectly capable of being machine-shaped at high rates.
