Definitions
- the present invention relates to a tamper-evident device for a stopper, in particular a plastic stopper intended for closing a bottle.
- This cap can be fixed on the bottle by screwing, snap-fastening or any other means.
- tamper-evident devices intended to allow viewing of a first opening of a stopper closing a bottle.
- the tamper-evident band has an internal annular ring, elastically deformable, intended to snap into place under a fastening collar provided at the lower periphery of the neck.
- the object of the present invention is therefore to provide a tamper-evident device which prevents any fraudulent re-use.
- the tamper-evident device which it proposes is intended for a stopper having a bottom and a skirt intended to be fixed on a neck of a bottle or the like. Additional fixing means are provided on the skirt and on the neck.
- This device comprises a tamper-evident ring intended to cooperate with a stop produced on the neck to remain around the latter, and according to the invention, it further comprises:
- the belt is advantageously connected to the tamper-evident ring by a tearable zone.
- This also has the advantage of having a connection between these two parts which can transmit relatively high torque or traction.
- Other embodiments allow the transmission of such a torque or such a tensile force.
- One can for example conform the facing edges of the tamper-evident ring and the notched belt and connect these two parts with breakable bridges. When a force must then be transmitted, the shape concordance of the slots makes it possible to transmit a torque while the bridges provide tensile strength.
- the device according to the invention preferably comprises, at the level of its belt, at least one plastic deformation zone.
- the stresses imposed on the belt cause an irreversible plastic deformation, making this belt unusable for new use.
- the axial stop is ruptibly connected with the belt.
- the device is then composed of three distinct elements: the tamper-evident ring, the belt and the axial stop.
- the axial stop advantageously takes the form of a cross member which extends diametrically over the bottom of the plug. This makes it difficult to access the bottom of the plug and makes it possible to produce an effective stop.
- the cross member preferably comprises a gripping tab to facilitate its removal by a user. This gripping tab can for example extend parallel to the skirt of the plug.
- the belt has an axial slot in which the gripping tab is housed and a ruptible connection is provided between the gripping tab and the belt on each side of the gripping tab. This allows the gripping tab to be integrated into the tamper-evident device and therefore to have an ergonomic and compact device at the same time.
- the tamper-evident ring has on its inner face protrusions extending radially intended to cooperate with at least one projection extending radially outwardly disposed on the neck of the bottle or the like to prevent rotation around the neck of the tamper-evident ring.
- the tamper-evident device according to the invention is particularly suitable for caps having a threaded skirt intended to cooperate with a thread produced on a neck of a bottle. However, it also adapts to snap-on caps, or fixed in any other way.
- FIG. 1 is a perspective view of a neck provided with a screw cap and a tamper-evident device according to the invention
- FIG. 2 is an exploded perspective view showing the three elements of the preceding figure separately,
- Figure 3 is an exploded perspective view showing the three components of the tamper-evident device described
- Figures 4 to 6 are sectional views along the section line IV-IV of Figure 1 showing a plug respectively equipped with a device of complete inviolability, of a tamper-evident device without cross and of a tamper-proof device without cross and without belt,
- Figure 7 is a view corresponding to Figure 2 for an alternative embodiment
- Figure 8 is a sectional view along the section line VIII-VIII of Figure 1 for the variant of Figure 7.
- Figure 2 shows a bottle neck 2 provided with an outer annular ring 4 and a thread 6 , a plug 8 having a bottom 10 and a tapped skirt 12 intended to cooperate with the thread 6 of the neck, and a tamper-evident device 14 intended to take place on the plug 8.
- All of these elements are preferably made of synthetic material and obtained by molding.
- the plug 8 is screwed in a conventional manner onto the neck 2.
- a chimney 16 is provided to seal between the plug and the neck. It extends parallel to the skirt 12 of the plug, from the bottom 10, and is of a diameter substantially equal to the inside diameter of the neck 2.
- the tamper-evident device 14 comprises a tamper-evident ring 18, a belt 20 and a crosspiece 22.
- the tamper-evident ring 18 is intended to come to take place essentially under the annular ring 4 of the neck 2 by surrounding the latter. It has on its inner face projections 24 extending radially inward. These protrusions 24 thus form notches which allow a first force fitting using a machine of the ring 18 on the neck 2 but which prevent a subsequent removal of this ring 18. These protrusions 24 also cooperate with stops 26 extending radially outwards, arranged on the neck 2 just below the annular ring 4, in order to prevent rotation of the ring 18 around the neck 2.
- the belt 20 comes to take place at the height of the skirt 12 of the plug. It surrounds the latter and extends substantially over the entire height thereof.
- a slot 30 substantially in the shape of a V and extending in the axial direction is formed in the belt 20.
- the point of the V is on the side of the tamper-evident ring 18.
- the crosspiece 22 extends above the bottom 10 of the plug. It comprises a bar 34 which passes diametrically through the plug. One end of the bar is at the level of the slot 30 and the other end is placed between the two plastically deformable zones 32.
- the end located on the side of the slot 30 is provided with a gripping tab 36 which is received in the slot 30.
- This tab 36 is thus substantially perpendicular to the bar 34. It is connected to the belt 20 by breakable bridges 38 which are therefore on the edges of the slot 30.
- the end of the bar 34 opposite to the gripping tab 36 is connected to the free upper edge of the belt 20 by means of breakable bridges 40 (FIG. 2).
- Ribs 42 extending here axially, are 8
- the entire tamper-evident device 14 is put in place on the cap 8 after filling the bottle and screwing the cap 8 onto the neck 2. It is therefore not possible to unscrew the cap to access the contents of the bottle without removing at least part of the tamper-evident device.
- the cap either by grasping it at the skirt 12, or by acting on the bottom 10.
- the belt 20 covers the skirt 12. By applying pressure on the belt, one can pass a couple of unscrewing on the skirt of the cap.
- the belt 20 is connected to the tamper-evident ring 18 which itself is blocked in rotation by the projections 24 and the stops 26.
- the tearable zone 28 is designed not to yield in the event of tangential shearing, even relatively large.
- the plug 8 would move axially and would then come into abutment against the bar 34 of the crosspiece 22. As long as the bar 34 is not removed, it cannot move axially because it is retained by the tamper-evident ring 18 via the belt 20.
- the plug 8 cannot therefore be unscrewed in this way for two distinct reasons, on the one hand because the belt 20 is locked in rotation and on the other hand because the plug 8 is blocked in translation.
- the tamper-evident device 14 In order to be able to unscrew the plug 8, it is therefore necessary to at least partially remove the tamper-evident device 14. The latter is designed to be removed as indicated below, with reference to FIGS. 4 to 6.
- FIG. 4 shows in section the neck 2 provided with its cap 8, itself covered with the tamper-evident device 14.
- the bar 34 is released by pivoting for example around the bridges 40 connecting the opposite end to the gripping tab 36 to the belt 20.
- the bridges 40 break during this pivoting, thus releasing the bar 34.
- the tearable zone 28 gradually yields over the entire periphery of the tamper-evident ring 18. During this separation of the belt 20 of the tamper-evident ring 18, the plastically deformable zones 32 are deformed under the effect of the constraints which are imposed on them.
- FIGS. 7 and 8 differs from the embodiment described above only at the level of the tamper-evident ring and therefore also at the level of the neck of the bottle.
- the same references used previously are therefore used for this variant.
- FIG. 1 The external perspective view of FIG. 1 corresponds both to this variant embodiment and to the embodiment described above.
- the tamper-evident ring 18 has two peripheral ribs 44 (only one is visible in Figure 7) intended to cooperate with the annular ring 4 to prevent withdrawal of the tamper-evident ring 18 of the neck 2.
- These ribs 44 only prevent axial movement of the ring 18 while leaving the latter a degree of freedom in rotation about the axis of the neck 2.
- the operation of this device is the same as that described more high. The only difference is that in case 11
- the tamper-evident ring 18 is not locked in rotation with respect to the neck 2. As explained above, it is still not possible to unscrew the plug because it comes to abut at its bottom 10 against the crosspiece 22.
- this tamper-evident device is very secure for the consumer, who can easily see whether the bottle offered for sale has already been opened or not.
- the belt can have another shape and for example not be provided with a slot.
- a tear-off area or ruptible bridges could replace this slot.
- a separate gripping tab can also be provided for the belt in order to facilitate the gripping of one end of the belt for tearing the connection zone with the tamper-evident ring.
- the shape of the bar illustrated in the drawing is given by way of example. Any other form can be considered.
- the bar does not necessarily join two diametrically opposite zones of the belt.
- a star-shaped barrette with three (or more) branches would be perfect.
- the means for blocking the rotation of the tamper-evident ring are not limited to protrusions facing counter-stops. A shape match can be chosen.
- the ring then has a shape which is not a shape of revolution, for example polygonal, and a complementary shape is produced on the neck.
- This device can also be adapted to another type of cap. It may be a plugged stopper, or intended to be fixed by any other means. This device can also be adapted to stoppers provided with pouring means and it is therefore unnecessary to remove from the neck of the bottle to dispense the liquid contained therein.
