• These faces 303a and 303b have a curved shape and more particularly concave.
• the top 300 having a width less than the basal wall 302, the faces 303a and 303b therefore diverge more significantly at the level of the basal wall 302.
• These faces 303a and 303b in this preferred embodiment thus form two opposite faces in image mirror from a plane of symmetry A axially passing through the edges 301 of the shutter member 3.

• the element 31 has a generally cylindrical configuration which is advantageously frustoconical, but this configuration is not limiting, many forms being able to be envisaged.
• the section of the element 31 is preferably regularly decreasing from the gripping element.
• the removal element 31 also has the function of facilitating the replacement of the closure member on the base.
• the element 31 advantageously comprises a free lower end 313, a junction surface 310, a latching bead 311 and a sealing surface 312.
• the free lower end 313 may include means for retaining fluid.

• the junction surface 310 is located between the free lower end 313 of the element 31 and the snap-on bead 311 while the sealing surface 312 is located between the bead d 'snap 312 and the basal wall 42 of the gripping element.

• the height at which the free end 313 of the element 31 extends can vary greatly.

As shown in FIGS. 1a and 1b, the shutter member 3, at the outlet of the mold, is connected by a bridge of annular material 23 to 1 'base 2. More specifically, the material bridge 23 rehe the junction surface 310 of the element 31 at a peripheral edge 200 formed by the radial plate 20.
• This configuration has the advantage of guaranteeing first-use security, the product contained in the reservoir 4 which cannot be extracted before breaking of the material bridge 23. This material bridge, during the first use, must therefore be broken.
• This rupture is effected by a pulling, pushing or rotating movement of the shutter member 3 relative to the base. Such a rupture then has the effect of creating a hole 24 defined by the peripheral edge 200 of the radial plate 20.

• the peripheral edge forming the orifice initially serves as an attachment point for the brittle material bridge and then as an annular sealing zone in cooperation with the sealing surface 312 of the shutter member.
• the element 31 could not be used for sampling and application but could be used only as a guide rod intended to facilitate the replacement of the obturation member. once the distribution is complete. Indeed, when the distribution is finished, the shutter member 3 is replaced so as to close the orifice 24.
• the element 31 naturally facilitates this repositioning since it suffices to let go of the element 31 at the orifice 24 to guide the organ shutter in relation to the base.
• the obturation member can be replaced.
• the shutter member can then define a closed reclosing position as shown in Figures 2a and 2b. This position allows the shutter member 3 to be firmly held on the base 2.
• a latching system is provided. This latching system implements cooperation between the peripheral edge 200 of the base 2 and the latching cord 311 of the element 31. This cooperation takes place following a pressure from the shutter member that is sufficiently strong. so that the peripheral edge 200 crosses the latching cord 311.
• the peripheral edge 200 retained by the latching cord 311 keeps the shutter member in the closed reclosing position. In this position, the peripheral edge 200 is then in leaktight engagement with the sealing surface 312 of the element 31, thus avoiding any possibility of product leakage between the element 31 and the base 2.
• FIG. 5 shows another configuration for the gripping element 30.
• the faces 303a and b are less concave, but have an upper part favoring gripping with a view to pulling in order to remove the shutter member from the orifice of the base.
• a simple pull exerted on the closure member 3 will allow the edge peripheral 200 to pass the latching cord 311 and thus to extract the element 31.
