Definitions
- the present invention relates to a cap for a container neck.
- the invention relates, in general, to plugs comprising a skirt which surrounds the neck of a container and a lower part of which, when it is considered that this neck extends vertically with its upwardly directed mouth, is intended to to remain around the neck after the first opening of the cap, possibly in the form of a tamper-evident band.
- the remainder of the skirt that is to say its upper part, is provided removable relative to the neck, while being initially connected to the lower non-removable portion of the skirt by a weakening line capable of being broken when the cap is first opened.
- the weakening line serves as a witness of this first opening, for the attention of users.
- this kind of weakening lines is made by cutting or molding.
- An example of this type of weakening line plug is provided by WO-A-99/5841 1 on which the preamble of claim 1 is based.
- the nature of the removable connection between the upper skirt portion and the container neck is indifferent, so that the invention also aims, for example, the so-called “snap" caps, it that is to say the plugs able to be clipped around the neck, that the caps screwed.
- the object of the present invention is therefore to improve the performance of the control means of the first opening of a plug.
- the invention relates to a cap for a container neck, as defined in claim 1.
- One of the basic ideas of the invention is to seek, by means of arrangements that are easy to implement and advantageously resistant to the initial placement of the plug around the container neck, to cause, without undue effort, the part of the user, one or more local plastic deformations around the skirt during the first opening of the cap.
- This or these plastic deformations have the advantage of being irreversible, which leaves visible traces around the skirt, easily identifiable by the user.
- the invention provides, on the one hand, to maintain a first "traditional" weakening line, with the difference that it is associated with one or more more resistant frangible bridges. at the break that the remainder of this line and, secondly, to achieve at least a second line of weakening, less extensive than the first following the periphery of the skirt, so that this second line is designated here by the "weakening segment” expression: this or each weakening segment is located, when it is considered that the axis of the skirt is vertical with its non-detachable part directed downwards, vertically above or below , as well as laterally on either side of the above-mentioned frangible bridge or bridges associated with the main weakening line.
- the weakening line in a first phase, breaks except for its aforementioned frangible bridge or bridges, which resist without being able to be driven upwards by the removable skirt portion due to the retention of the non-removable skirt portion around the neck of the container.
- the upward movement of the removable skirt portion causes the plastic deformation of the strand interposed between the line of weakening and the weakening segment, more precisely the deformation of at least one the two lateral arms of this strand, arranged on either side of the associated frangible bridge, by relative distance of the edges of the weakening segment.
- the opening of the stopper passes into a second phase, in which the frangible bridge or bridges of the weakening line are broken in turn, thus making it possible to clear this removable skirt portion vis-à-vis the non-removable skirt portion retained around the neck.
- the cap is closed, that is to say if the removable skirt portion is repositioned around the container neck in its initial position before the first opening, it is impossible to reposition as in the origin or the strands because of their irreversible plastic deformation. This or these strands found at least partially projecting vis-à-vis the rest of the skirt, which provides a clear indication, so easy and quick to observe for the user.
- the invention provides, on the one hand, to maintain a first "traditional" weakening line, with the difference that, at the axial level of this weakening line, the skirt includes one or a plurality of non-breakable portions, which will not break during the breaking of the line of weakness and, secondly, to achieve at least a second weakening line, less extensive than the first following the periphery of the skirt so that this second line is referred to herein as the "weakening segment".
- this or each weakening segment is located, when it is considered that the axis of the skirt is vertical, vertically above or below the above-mentioned non-frangible skirt portion or portions.
- the strand of material located vertically between the line of weakness and the weakening segment, has a running portion which extends along the aforementioned non-breakable skirt portion, while the peripheral ends of this strand are frangibly connected, by two ad hoc opposed bridges, to the skirt portion, removable or non-removable, wherein the second weakening segment is delimited.
- the weakening line in a first phase, breaks while, at the same time, the aforementioned frangible bridges are sized to withstand, while undergoing each a plastic deformation stress related to the relative drive between the removable skirt portion and the non-removable skirt portion retained around the neck.
- the current portion of the aforementioned strand remains firmly attached to the skirt portion, removable or non-removable, wherein the weakening segment is not defined by the non-breakable skirt portion mentioned above.
- the opening of the stopper passes into a second phase in which the frangible bridges located at the peripheral ends of the strand in turn break, thus making it possible to completely disengage the portion skirt removable vis-à-vis the non-removable skirt portion retained around the neck.
- the running portion of the strand imparts a crenellated shape to the skirt portion to which this current portion is non-frangibly bonded.
- the stopper according to the invention can be handled reliably and efficiently before its first opening, then provide, during this first opening, a blunt opening indication, without increasing the opening force to be applied. by the user.
- the clear opening indication provided by the invention is of major interest when the non-removable portion of the skirt remains completely immobile with respect to the neck after breaking any connection with the removable skirt portion. This is particularly the case for plugs whose non-removable skirt portion has a large axial dimension, inducing immobilization interference with the neck.
- the weakening line and the weakening segment of the plug according to the invention can be made both by cutting and by molding.
- the realization of the weakening segment is simple and fast, especially when this segment is provided in that of the removable and non-removable skirt portions, which has a significant axial dimension.

- the skirt portion 1012i When the user first opens the stopper 1000 by rotating the skirt portion 1012i about the axis XX to unscrew it from the neck 2, the skirt portion 1012 2 is retained, in the direction of the axis XX, by the boss 6 while the skirt part 1012 ! is removed from the skirt portion 1012 2 upwards.
- the weakening line 1020 and the weakening segment 1028 are solicited together, as shown progressively in FIGS. 16 to 18.
- the ends 1032 2 and 1032 3 of the 1032 strand are deformed plastically, passing gradually from their initial configuration to a plastically stretched configuration, as can be seen by comparison of FIGS. 12, 16 and 17.
- the frangible bridges 1034 connecting the ends of strand 1032 2 and 1032 3 to the removable skirt portion 1012-1, undergo stresses of plastic deformation, without however breaking.
- the cross section of the bridges 1034 tends to decrease by stretching the material.
- the frangible bridges 1026 are broken while the frangible bridges 1034 deform plastically without breaking.
- the art jumpers 1026 are essentially subjected to shear stresses, which, in view of their design, quickly leads to their rupture when sufficient torque is applied between the removable skirt portions 1012-1 and non removable 1012 2 , while the bridges 1034 work essentially in tension-compression, which, in view of their design, leads to their progressive plastic deformation as the parts of skirt 1012 ⁇ and 1012 2 move away from each other in the direction of the XX axis.
- the effort required for the progressive plastic deformation of the bridges 1034 is limited, even negligible, compared to the overall effort that it must produce to rotate the removable skirt portion 1012. all the more the case when, advantageously, the peripheral dimension of the ends 1032 2 and 1032 3 of the strand 1032 is limited compared to that of the entire strand 1032.
- the peripheral extent of each end strand 1032 2 , 1032 3 is less than 10% of the total peripheral extent of the strand 1032, which is to say that the peripheral extent of the non-breakable skirt portion 1025 is at least 80% of the peripheral extent of the weakening segment 1028.
- the bridges 104 are designed to work in tension-compression and thus resist breaking more than the bridges 1026 working in shear, presents another interest: indeed, during the handling of the stopper 1000 before its first opening, in particular during its manufacture, as well as during its initial placement, in particular by screwing, around the container neck 2, the bridges 1034 reinforce the breaking strength of the weakening line 1020, which increases the mechanical resistance of all of this line of weakening and the weakening segment 1028, thus avoiding that line and this segment begin to break, which would alter their performance of subsequent indication of the first opening of the plug.
- the bridges 1034 make it possible, in a way, to protect the integrity of the frangible bridges 1026 during the manufacture and the initial installation of the plug 1000.
- the first opening phase is terminated in favor of a second phase of operation, during which the 1034 bridges break, as shown in Figure 18.
- the skirt portions 1012 ! and 1012 2 are then completely separated from each other and the unscrewing of the skirt portion 1012i can be continued until the complete disengagement of the threads 5 and 1016.
- the bridges 1034 can be used in the manner of hinges to tilt the skirt part 1012 !
- the bridges 1034 are then easily broken by hand by the user, in particular with a view to resealing the neck 2, repositioning by screwing the skirt part 1012i around this collar.
- the appearance of the stopper 1000 is that shown in FIG. 19: it is impossible to reposition the strand 1032 in its original configuration, due to the plastic deformation of its peripheral ends 1032 2 and 1032 3 . As a result, part of the strand 1032 then hangs in the void, protruding from the outer face of the skirt 1012.
- the skirt portions 1012i and 1012 2 can no longer be placed in a substantially contiguous manner, as they were before the first opening of the stopper 1000, in particular because of the interposition of one or both deformed ends 1032 2 and 1032 3 1032 stranded, as shown in Figure 19.
- a portion of the body 4 of the neck 2 is then directly observable, on the one hand, directly above the weakening segment 1028, and, on the other hand, between the skirt portions 1012-1 and 1012. 2 not joined: by choosing contrasting colors for the skirt 1012 and the body 4 of the neck 2, there is a better visual indication that the plug 1000 has already been opened a first time.
- the stopper 1000 in particular made of plastic material, it is possible to use either a molding and then a cutting process, or an exclusively molding process.
- cutting blades are used to perform, preferably concomitantly, the weakening line 1020, with the frangible bridges 1 026, and the weakening segment 1028, causing relative to each other the skirt 1012 and these rotating cutting blades around the XX axis.
- the skirt 1012 is molded by integrating the presence of the weakening line 1020 and the weakening segment 28.
- non-frangible skirt portions 1025 may be provided at the axial level of the line of weakness 1020, being distributed substantially uniformly around the skirt 1012 and respectively being associated with as many weakening segments 1028;
- the slot 1024 of the weakening line 1020 can be uninterrupted;
- the slot 1030 of the weakening segment 1028 can be interrupted by one or more frangible bridges connecting the current portion 1032 ! strand 1032 to the remainder of the removable skirt portion 1012-1 before the first opening of the stopper 1000; such frangible bridges can enhance the overall strength of the weakening segment 1028 during demolding and assembly of the cap around the container neck 2;
- weakening segment can be defined in the part of non-removable skirt 1012 2, which amounts to di re that su iva nt the orientation es Figures 12 and 13, the weakening segment is no longer disposed above the weakening line 1020, but below it; in this case, the current part of the strand is bonded in a non-friable manner to the part of ju pe a movible, while the peripheral ends of this strand are each connected to the non-removable skirt portion by respective frangible bridges. functionally similar to bridges 1034;
- the embodiment of the invention corresponding to the stopper 1000 is of particular interest for screw caps; however, the invention can be applied to plugs having other types of removable fastening on the container neck 2, such as clipping fastening, the skirt portion 10 being provided internally with a clipping band, optionally fragmented into several distinct clips, capable of being engaged with a projecting outer edge, provided at the upper end of the neck; and or
