STOPPER HAVING A SLIDING PLUG AND COMPRISING MULTIPLE DISTRIBUTION HOLES
A stoppering device to be secured to a container neck comprises a tubular spout (18) defining a passage opening (24), and a plug. The plug (12) has an outer tubular shell (42) sliding on the tubular spout (18), and a bottom (44) provided with a sealing skirt (52) and multiple distribution holes (54). The bottom (44) of the plug engages with the connecting wall of the tubular spout (18) in the plugging position, while preserving an annular retention space (60) between the bottom (44) of the plug and the tubular spout (18). The bottom (44) comprises radial ribs (56) which are in an alternating arrangement between the distribution holes (54), and constitute retention facets retaining the liquid held in the retention space by adhesion. The small volume of liquid which, during the plugging phase, would be prevented from flowing back into the container closed by the stoppering device, can remain in the annular retention space without any particular risk of abrupt ejection, said retention being promoted by the presence of multiple walls in the chamber, in particular the retention facets.
The invention relates to a cap (10), comprising a first portion (12) made of a plastic material and forming a bottom (16) for covering a container neck (36) and a protective side wall (18) for surrounding the container neck, and a second portion (14) made of a flexible material that is compatible with the plastic material of the first portion and separate from the plastic material of the first portion, the second portion being annular and consisting of a flexible seal, which projects from the bottom (16) toward the interior of the side wall and which is welded to the first portion. The first portion may comprise an annular projection projecting from the bottom, the second portion being welded to the annular projection. Thus, the manufacture of the stopper by molding consists of the following plurality of consecutive steps: in a first phase, a flexible material is injected in order to produce the flexible annular seal; and then the movable portions of the mold are placed such that the flexible material is arranged in a groove that is set back from the planar surface of the mold, thereby defining the inner surface of the bottom of the stopper. When the plastic material is injected into the mold, the plastic material fills the available space in the groove above the flexible material. The groove ensures the integrity of the shape of the interface between the two materials.
A stopper device (10) has a base (14) and a cap (12), the base having at least one housing (34). At least one first-opening marker (46). The base (14) has a cover (40) separating the outer radial opening (38) from the upper axial opening (36) and delimiting an upper part (34S) of the housing, the first-opening marker (46), in the closed position of the cap (12), being located in the upper part (34S) of the housing and concealed by the cover (40), the first-opening marker (46) being able, after the opening marker (46) and the cap (12) have been separated, to drop into a lower part (341) of the housing, the radial opening (38) being disposed so as to render the first-opening marker (46) that has dropped into the lower part (341) visible.

According to the invention, the bottom includes a plurality of holes flaring towards the outside of the cap and arranged radially outside the annular lip (5).
The present invention relates to a stopper for affixing to the neck of a container of liquids, comprising: a main body provided internally with a means of connection to said neck and surmounted by a tubular projection having an outer wall defining a reference axis; a cap covering said tubular projection and provided internally with elastic engagement means which engage with a groove in the tubular projection; a tamper-resistant ring continuing on in the distal direction from said cap, to which it is connected by evenly spaced frangible bridges separated from one another by incisions. According to the invention, said ring is provided with teeth shaped to engage with evenly spaced mating protuberances on a proximal end of the main body, the teeth and/or protuberances having a chamfered prismatic profile.
The present invention relates to a cap to be secured on the neck of a container for liquids, including: a spout (100), a tubular stopper (2), and a bottom (3) formed with one or more holes (4), characterised in that the outer wall (12) of the annular projection (1) and the guiding skirt (20) of the stopper are shaped so as to slide relative to each other so that, in a first opening phase starting from the blocked position up to an intermediate position between the blocked position and the open position, the guiding skirt (20) slides on the outer wall (12) with an resultant axial friction not exceeding a predetermined threshold value F1, and so that, in an eventual opening phase, the annular elastic skirt (5) is not in contact anymore with the tubular wall (11), wherein the resultant axial friction between the outer wall (12) and the guiding skirt (20) increases continuously up to a maximum value F2 such that 10N < F2-F1 < 20N.
The invention relates to a plug that comprises two parts, the first part (2) Defining a base and including an annular groove (5) defining a geometrical mounting axis and an elastically deformable latching relief (18), the second part defining a hood (6) and including a fixation ring (80) inserted in said groove (5) and maintained in position by the latching relief (18), a cap (60) formed with a top blocking wall (19) and at least one sealing skirt (22), and means (7) for pivoting the cap (60) relative to the ring (80) between an open position for accessing the pouring shaft (50) and a blocking position in which the sealing skirt (22) interacts with the base while the blocking wall covers said shaft (50). The hood (6) includes an abutment (70) and the base includes a counter buffer (71) interacting with the abutment (70) for indexing the angular position of the base (3) relative to the hood (6) about the mounting axis. It is thus possible to mount the two parts according to a simple method that combines a translation closing-in movement of the two parts and a rotation movement that is interrupted when the abutment is in contact with the counter buffer.
