Abstract: A housing (1, 1?) for a pressurized container, has a bottom (12, 12?) a stopper, sealing means (124, 124?) to ensure sealing between the stopper (2, 2?) and the housing (1, 1?) when the housing is provided with a stopper; and retaining means (126, 126?) to retain, when the container is pressurized, a stopper (2, 2?) closing the opening. The retaining means (126, 126?) are distinct from the stopper (2) and are in an inactive initial form (125, 126) and must, in order to fulfill their function, be activated (126, 126?) after the opening has been closed by a stopper.

Abstract: The invention relates to a dispensing module for two liquid products, comprising: a first chamber (20) having a first wall, said first chamber having a first opening; a first piston (61) which can be displaced while resting on the wall of the first chamber; a second piston (64) which can be displaced while resting on a wall of the second chamber, and coupling means (62) for coupling both pistons while the product is being dispensed are provided. According to the invention, in order to prevent functional dysfunctions in the event of a distortion of the shape of container and to freely select the shape of the container, said dispensing module comprises a second chamber, the wall of which can be displaced while resting on the second piston, said second chamber comprising a second opening. This is achieved by virtue of the fact that the distortion of the container no longer leads to functional dysfunctions of the dispensing module. Also, the outer shape of the container can be freely selected.

Abstract: An injection-molding press for overmolding a second part onto a first part (8) includes a movable portion and a fixed portion, with a first mold element (11, 12) on one of the press portions and a second mold element (20) on the other press portion so as to form a cavity (C) between the mold portions when the press is closed.

In the closed position of the press with a first part (8) in the first mold portion and the first support surface (125a) advanced in the working position, at least a portion (8b) of the front end of the first part (8) is clamped between the two support surfaces (125a, 22a), forming a tight seal for the cavity (C).

Abstract: A press for manufacturing a one-piece object includes two rotary plates (110, 210) which are parallel but offset, each carrying a mold (120, 220) having two portions. Each mold portion can be placed above or below, so that the mold portion (121) of the first mold situated above faces the mold portion (222) of the second mold situated below. First parts of the object, for example skirts, are inserted in the press in an insertion zone (Z1). In parallel, second parts, for example caps, are introduced into an introduction zone (Z2). In a common zone (Z3), third parts, for example dispensing heads, are overmolded on the first and second parts brought close in the common zone in the same position as in the finished object. After opening the press, the plates are turned so that the finished objects are in the portion of the second mold which is above.
