摘要:
A method for the compression molding of a plastic part including a neck which is equipped with an orifice, in which a blank is created and compressed. The part is molded with a neck which is equipped with a top wall including a thin area with a notch, the contour of this thin area defining the orifice, and two zones which can withstand the mechanical stress necessary in order to break the top wall at the notch. One of the two zones is intended to transmit the mechanical stress and the other is used as a support. The section of the notch is slightly inclined in relation to the axis of the neck. After molding, mechanical stress is applied to one part of the top wall, other than the thin area, so that the top wall tears at the notch, 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 axes 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.

A hinged-lid closure equipped with a lid and a base including a plate, an attachment skirt and an external lateral skirt, where the attachment skirt is thicker than the plate and the external lateral skirt. The base is equipped with a radial longitudinal rib attached to an internal surface of the external lateral skirt and located in a plane mid-perpendicular to the hinge.

摘要:
A double dispensing container including an outer container and an inner container, each container including a body and a head provided with a neck and a shoulder linking the neck to the body, the neck having a side wall and one or more dispensing orifices, the neck of the inner container being housed inside the neck of the outer container and having a section such that it provides one of more outflow passages for a pasty product A and, in combination with the inner surface of the outer container neck, one or more outflow passages for a pasty product B emerging onto a single or multiple orifice dispensing the product B. The inner neck is extended by a summit portion which is linked to the inner neck via a thin annular zone and which closes the single or multiple orifice dispensing product A.
摘要:
A metal capsule stopper placed over the cork, more especially on bottles for champagne and sparkling wines and in general, all bottles containing aerated or carbonated liquids or beverages, to eliminate conventional cork wiring without a change in the appearance of the bottles. This capsule is crimped on the bottle, which has a screw-ring. It has, on its outer surface, ribbings which are substantially parallel to the vertical axis of symmetry of the bottle and capsule and into which the cork may expand.

The preparation of blanks from which stampings are formed by forming a sandwich of at least two foils, at least one of which is a thermoplastic material and in which the foils are adhered one to the other at least temporarily only in the regions from which the stamping blanks are to be formed to enable the blanks to be cut out while leaving the remainder free for separation and recovery to prevent waste.

This invention relates to the production of an elongated rolled rim on a metal container in which, in a first operation, the rim of the container blank, which has previously been leveled off, is rolled over by a tool which is displaced parallel to the axis of the container and the end of the operating travel of which is determined by its distance from the plane of the outside face of the bottom of the container, and in a second operation, the rolled-over portion is pushed downwardly by a second tool whose operational engagement surface is different from the first tool and whose operating travel is also limited by its distance from the plane of the outside face of the bottom of the container, the difference between the two distances determining the height of the rolled rim of the container.
