Definitions

• the present invention relates to a capsule for the hermetic sealing of a container with an attachment flange.
• Traditional capsules are produced by molding and generally include a cover surmounting a side skirt which is provided, in its lower part, with snap-fastening means under said collar and, in its upper part, with a removable tamper-evident band made on a portion of the periphery of the skirt where it provides temporary connection with said cover by providing a hinge on the complementary portion.
• the cover does not remain in its fully open position.
• the plastic material used in particular for producing the hinge has a shape memory which tends to recall it towards its original position when it leaves the mold, corresponding to a closing of the cover.
• the equilibrium position of the cover corresponds to an opening which is only partial, which hinders the distribution of the product.
• the present invention aims to solve this technical problem satisfactorily.
• said hinge consists of two bridges delimiting between them a lumen in which extends said locking tab.
• each of said bridges comprises a cavity delimiting a preferential zone of elastic deformation allowing the pivoting of the cover.
• said cavity is bordered laterally by two reinforcing ribs.
• said stud is located below the level of said cavity in the closed position of the cover.
• said stud extends radially outward in the closed position of the cover.
• said stud has a bevelled outer lateral face guiding the tab in contact with said flange.
• said stud has a trapezoidal cross section forming a hook.
• said locking tab is provided with a stiffening element resting on its internal face to prevent it from bending inwards.
• one of the ends of the tamper-evident band is provided with a tongue.
• said tongue is housed in a corresponding cutout in the side skirt.
• said means for latching the skirt under the collar consist of a partially peripheral internal ring while the lower edge of said skirt abuts against a lower shoulder of the neck of the container.
• said side skirt is attached to the cover plumb with its peripheral edge so as to define before snapping onto the container a cylindrical envelope.
• the capsule is capable of further comprising a cylindrical sleeve integral with the underside of said cover and intended to be inserted inside the container in leaktight contact with its upper internal wall.
• peripheral edge of the cover is provided, in the zone diametrically opposite the hinge, with a cutout.
• the capsule of the invention offers a stable full opening position allowing easy distribution of the product in all circumstances.
• the passage of the cover from the closed position to the fully open position is carried out without significant effort.
• the capsule of the invention is particularly simple and therefore easy to produce and offers a complete set of functionalities for an economic cost price.
• FIG. 1 shows a side view of an embodiment of the capsule of the invention
• - Figure 2 shows a sectional view along AA of the capsule of Figure 1 during mounting on a container
• - Figure 3 shows a sectional view along BB of the capsule of Figure 1 after mounting on the container;
• FIG. 4 shows a sectional view along CC of the capsule of Figure 1 after removal of the tamper-evident band
• FIG. 5 shows a sectional view along BB of the capsule during the opening of the cover
• FIG. 6 shows a sectional view of the capsule, still along BB after locking the cover in the fully open position.
• the capsule of the invention is intended to ensure the tight closure of a container whose upper part or neck is provided with a hooking collar.
• This capsule is preferably produced by injection or compression molding of an elastically deformable plastic.
• the embodiment of the capsule shown in Figure 1 consists of a cover 1 surmounting a side skirt 2 which is provided in its lower part with latching means under the flange C of the container R (see Figure 2).
• the skirt 2 is also provided, in its upper part, with a removable tamper-evident band 12.
• the skirt 2 is attached to the cover 1 directly above its peripheral edge 1a.
• the tamper-evident band 12 provides the removable and temporary connection between the cover 1 and the skirt 2.
• the band 12 is attached to the cover 1 and to the skirt 2 by a fragile peripheral film 20 capable of being broken or torn.
• the tamper-evident band 12 carries a tongue 22 which extends downwards and at least part of which, here the bottom part, is free, that is to say free of film 20.
• the tongue 22 is produced at one of the ends of the strip 12 and is housed at rest in a coplanar manner with the skirt 2 and the strip 12 in a corresponding cut 2a so as to define, before snap-fastening on the container R , a substantially cylindrical envelope.
• the strip 12 is produced only on a portion of the periphery of the side skirt 2 by providing a hinge 21 on the complementary portion.
• the hinge 21 consists of two bridges 21a, 21b delimiting between them a lumen 26. As is also apparent in FIG. 4, each of the bridges 21a, 21b comprises a cavity 210 delimiting a preferred zone of elastic deformation and / or bending allowing the pivoting of the cover 1 upwards.
• the cavity 210 is bordered laterally by two reinforcing ribs 211.
• the cover 1 carries a locking tab 24 whose free end is provided with a retractable projection or stud 25 capable of cooperating with the flange C of the container to retain the cover 1 in the fully open position.
• the locking tab 24 is housed in the slot 26 and the stud 25 extends radially outward when the cover 1 is closed.
• FIGS. 3 and 4 show a sectional view of the embodiment of Figure 1 at the start of installation on the container R.
• the capsule further comprises a cylindrical sleeve 10, integral with the underside of the cover 1.
• This sleeve 10 is intended to be inserted inside the upper part or the neck of the container R, in leaktight contact with its internal wall (see FIGS. 3 and 4).
• the latching means of the skirt 2 are not yet locked under the flange C of the container R.
• These means consist of an internal ring 23 partially peripheral which is, in this position, in support on the flange C.
• the tamper-evident band 12 and its tongue 22 are attached to the underside of the cover 1 at a distance from its peripheral edge 1a which corresponds substantially to the thickness of their projecting external parts, in order to obtain a substantially cylindrical envelope.
• the external face of the tongue 22 is here produced in the form of a cylinder portion comprising, where appropriate, an internal cavity.
• the lower and upper edges of the strip 12 and the tongue 22 are preferably bevelled.
• the internal face of the tongue 22 of the tamper-evident band 12 is provided with a boss 22a.
• the boss 22a is located on the skirt 2 at substantially the same height as the internal ring 23, so that in the position shown in FIG. 2, it is, like him, in abutment on the flange C.
• the boss 22a has a profile with at least two and preferably three planar facets.
• the upper facet 220 and the lower facet 221 are inclined at an angle between 20 ⁇ and 40 ⁇ relative to the vertical axis of the boss.
• the central facet 222 is in turn parallel to this axis.
• the upper facet 220 is inclined in order to facilitate the ejection of the mold during the manufacture of the capsule.
• FIG. 3 shows the same embodiment of the capsule after snap-fastening in its final mounting position.
• the geometry of the boss 22 is determined as a function of that of the flange C to obtain the amplitude of the desired pivoting.
• the snap-fastening therefore makes it possible to automatically put the tongue 22 projecting relative to the plane of the side skirt 2, and thus to offer a means of gripping the tamper-evident band 12.
• the lower edge 2b of the side skirt 2 is in abutment against a lower shoulder T of the neck of the container R.
• the locking tab 24 is substantially perpendicular to the lower periphery of the cover 1 and is provided with a stiffening element 27 inclined outwards and downwards by pressing on the internal face of said tab 24.
• the stud 25 has a trapezoidal cross section forming a hook and has an outer side face 25a bevelled.
• the stud 25 is located below the level of the cavities 210 of the bridges 21a, 21b.
• FIG. 4 still represents the same embodiment of the capsule after removal of the tamper-evident band 12 and of its tongue 22 by tearing and then by trimming the film 20.
• FIG. 5 shows the same embodiment of the capsule during the opening of the cover 1.
• the user lifts the cover 1, for example by grasping its peripheral edge 1a by the cutout 2a.
• the elastically deformable nature of the material constituting the capsule makes it possible to obtain the opening of the cover 1 by bending and / or deformation of the bridges
• the container R is opened by pivoting the cover 1 upwards around an axis passing through the hinge 21, driving the sleeve 10.
• the sleeve 10 is gradually released by sliding and, if necessary, being elastically deformed in contact with the internal wall of the neck of the container. Jointly, the stud 25 of the locking tab 24 comes into bearing contact on the flange C of the container.
• the stiffening element 27 acts on the back of the tab 24 to prevent it from bending inwards, but given its inclination, it leaves the tab 24 free to bend outwards.
• the pivoting of the cover 1 upwards therefore causes the tab 24 to bend outwards, which has the effect of retracting the stud 25 whose bevelled face 25a guides the tab 24 in contact with the flange C.
• FIG. 6 shows the capsule in the open position with the cover 1 which extends about 90 ° from its initial closing position.
• This blocking which is reinforced by the action of the stiffening element 27 ensures the stable maintenance of the cover 1 in the fully open position regardless of the orientation of the container R.
• the return of the cover 1 in the closed folded position is effected by manual pressing on its external face by slightly forcing its side wall and the stud 25 when the flange C.
