Description

BOTTLE CLOSURE DEVICE
The present invention refers to a bottle closure device".
Various bottle closure devices generally made up of a cap and a dispenser or diffuser are currently known. The cap has an inner thread suitable for being engaged, for opening and closing the bottle, with a corresponding thread provided on the outer surface of the dispenser.
This latter is pressure-fixed in the opening of the bottle neck or, through known means, on the bottle neck .
Furthermore, a further sleeve is generally provided for covering the cap, made of aluminium or plastic film.
Thus, the assembly of such closure devices provides for a first step of screwing the cap on the diffuser and subsequently inserting the cap/diffuser assembly into the covering sleeve which adheres to the cap achieving an embedding engagement with the same.
Generally, in the production lines, once assembled, the aforementioned closure devices are subsequently applied on the respective bottles.
In some cases it is possible that during the moving of the closure device the covering sleeve and the cap disengage from each other causing the slipping of the cap and of the diffuser connected thereto inside the covering sleeve.
This may cause the occurrence of defects in the assembly of the single closure device on the respective bottle and damage on the very device, determining a production drop and a cost increase. In fact, in these cases the bottles not correctly assembled are discarded and possibly reintroduced into the production line in order to be subsequently closed through a new closure device.
Furthermore, it is worth to underline that the closure devices currently known do not permit to guarantee the wholeness state of the bottles which they are applied to. In fact, the covering sleeve of such devices may be slipped off without being damaged thus permitting the unscrewing of the cap and the ensuing opening of the bottle to alter the content of the very bottle.
An object of the present invention is that of overcoming the aforementioned drawbacks and in particular that of providing a bottle closure device capable of permitting a simple and safe capping of such bottles .
These and other objects according to the present invention are achieved by providing a bottle closure device as outlined in claim 1.
Further features of the bottle closure device are subject of the dependent claims.
Features and advantages of a bottle closure device according to the present invention shall appear clearer from the following non- limiting and exemplifying description with reference to the schematized attached drawings wherein:

- figure 10 is a perspective view of the closure device of figure 1;
figure 11 is a perspective view of a further embodiment of the closure device according to the present invention
With reference to the figures, a bottle closure device is shown, which is wholly indicated with 10.
Such closure device 10 comprises a cap 11, having a first flat upper portion 12 and a side tubular portion 13, and a covering sleeve 20.
The closure device 10 develops along an axial direction A as indicated in the figures.
The closure device 10 may comprise a diffuser 14 possibly provided with at least one drop breaker (not illustrated). Such diffuser 14, in particular, may be made as an independent element or it may coincide with the end portion of a neck of a bottle.
Should the diffuser 14 be obtained as an independent element, such diffuser 14 is arranged to be coupled - at the upper part - with the cap 11 and - at the lower part - with a bottle neck (not illustrated) .
As observable in figure 3, the side tubular portion 13 of the cap 11 is provided with an inner thread 40, suitable for being engaged with a corresponding thread 41 of the diffuser 14.
The engagement between the thread 40 of the inner side portion 13 of the cap 11 and the thread 41 of the diffuser 14 results in the closing of the cap 11 on the diffuser 14 and hence of the closure device 10 on the bottle neck.
Obviously, other types of coupling different from those described above and shown in the figures are also provided in the invention.
Preferably, the threading 40 is of the multi principle type and it is obtained in such a manner that the cap 11 may be fitted on the diffuser 14 without requiring using means for the orientation and positioning of the cap 11 with respect to the diffuser 14.
The covering sleeve 20 comprises an upper portion 21 and a lower portion 22 connected to each other along a breaking line 23 provided with a plurality of connecting bridges 24, which are, necessarily, lacerated during the first opening of the bottle. In particular, as observable in figures 7b or 9b, the connecting bridges 24 are advantageously obtained within the covering sleeve 20, leaving the lower edge of the upper portion 21 and the upper edge of the lower portion 22 free and entirely facing each other.
Thus, the upper portion 21 and the lower portion 22 may be obtained through a cut of the covering sleeve which is continuous along the entire annular perimeter line. Furthermore, the upper portion 21 may be positioned at any distance from the lower portion 22.
Preferably, the upper portion 21 is arranged at contact with the lower portion 22, conferring greater compactness to the closure device 10.
The covering sleeve 20, when the closure device is assembled, is coupled to the cap so that the upper portion 21 at least partially covers the side portion 13 of the cap 11.
In the particular illustrated embodiment the side portion 13 of the cap 11 extends - at the lower part - beyond the breaking line 23, though it is possible to make a covering sleeve 20 so that the upper portion 21 entirely covers the side portion 13 of the cap 11.
Furthermore, the upper portion 21 of the covering sleeve 20 is closed at the upper part. At the top part of the aforementioned upper portion 21 of the covering sleeve 20 at least one perimetrally developing opening 33 is preferably made.
According to the present invention, the plurality of connecting bridges 24 comprises means 25 for constraining to the axial movement of the cap 11 with respect to the covering sleeve 20.
Thus, once the covering sleeve 20 is applied on the cap 11 coupled to the diffuser 14, the constraining means 25 stop the movement of the cap 11 with respect to the covering sleeve 20 along the axial direction A, guaranteeing the coupling stability between them.
In a preferred embodiment of the present invention such constraining means 25 comprise a plurality of abutment portions 25 made on the plurality of connecting bridges 24; such abutment portions 25, in particular, protrude towards the inside of the covering sleeve 20 so as to form a stopping abutment for the cap 11.
Alternatively, the constraining means comprise an annular abutment portion 36 made on the inner surface of the covering sleeve 20 at the lower end of the cap 11. . In this case, the annular abutment portion 36 may be made as an enbloc with the connecting bridges 24 ; otherwise the connecting bridges 24 may lie against the annular abutment portion 36 as illustrated in figure 9b.
Preferably, the abutment portions 25, 36 are made at the lower portion 22 of the covering sleeve 20, as observable in particular in figure 7b.
Alternatively, should the upper portion 21 of the covering sleeve 20 be made so as to entirely cover the side portion 13 of the cap 11, the abutment portions 25, 36 can be obtained at the upper portion 21.
Advantageously, the upper portion 21 of the covering sleeve 20 comprises a first weakening line 26 which extends axially for a first tract, a second weakening line 27 placed side by side to the first weakening line 26 which extends axially for a second tract shorter with respect to the first tract, and a third weakening line 28 which connects the aforementioned first 26 and second 27 weakening lines extending beyond at least one of them.
By weakening line it' is to be intended a portion of the sleeve configured so as to lacerate before the remaining portion of the very sleeve.
By the term "axially" it is to be intended the fact that the weakening lines are obtained along some generatrices of the side portion of the outer sleeve. Preferably the weakening lines 26, 27 and 28 are made by means of respectively a first, a second and a third slot which define a gripping and tearing lip 29.
Such a gripping and tearing lip 29, as shown for example in figure 1, can be provided - at the upper part - with a fin portion 35 to facilitate the holding of the lip 29.
Alternatively, the weakening lines 26, 27 and 28 can be made, for example, by means of thinning of the upper portion 21 of the covering sleeve 20.
As observable for example in figure 1, the third slot is preferably perpendicular to the first 26 and to the second 27 slot, but more generally it can be transverse along any direction with respect thereto, thus making a kind of L- shaped portion for gripping and tearing the outer sleeve.
Preferably, the first 26 and the second 27 slot extend starting from the upper free edge 30 of the upper portion 21 of the covering sleeve 20.
In such case, preferably, the third slot 28 is made at such upper free edge 30.
Advantageously, the first slot 26 extends axially from the upper free edge 30 up to the breaking line 23 without leaving any bridge of residue material on the upper portion 21 of the covering sleeve 20.
Preferably, as illustrated in figure 9a, the third slot 28 extends beyond the second slot 27 and it is separated from the at least one slot 33 by at least one connecting arc 37. In such a way the upper portion 21 is weakened and this facilitates its breakage upon grasping the tearing lip 29.
Furthermore, with the aim of facilitating the grasp on the tearing lip 29 and further weakening the upper portion 21 the second slot 27 may be obtained as a V- shaped slit having at least one of the two arms inclined with respect to the axial direction A, as illustrated in figure 11.
Furthermore, in the particular embodiment illustrated in the attached figures the lower portion 22 of the covering sleeve 20 comprises an blocking internal annular projection 31 suitable for being engaged with a corresponding external annular projection 32 made on the diffuser 14 when the closure device 10 is assembled.
Thus, following the first opening of the bottle once the upper portion 21 of the covering sleeve 20 has been removed, the lower portion 22 remains coupled to the diffuser 14.
The description outlined above clearly shows the features of the bottle closure device subject of the present invention, as well as the relative advantages. Actually, according to the present invention, the means for constraining to the axial movement of the cap with respect to the covering sleeve allow mounting the closure device on a bottle in a simple and safe manner thus guaranteeing the sealing of the assembly of the very closure device.
Such constraining means prevent the covering sleeve from being slipped off even only partially during the capping process, ensuring the correct mounting of the closure device on the bottle.
Furthermore, the constraining means constrain the opening of the bottle to the breakage of the breaking line between the upper portion and the lower portion of the covering sleeve and to the subsequent removal of the very upper portion. Thus, the opening of the bottle is revealed.
According to the present invention, the gripping and tearing lip defined by the three slots can be easily pulled in order to break the connecting bridges along the breaking line and to remove the upper portion of the covering sleeve from the closure device. In fact, the third slot intersects the first and the second slot extending beyond at least one of them as observable in the attached figures; this weakens the upper portion of the covering sleeve, facilitating the breakage once the gripping and tearing lip has been gripped.
Lastly, it is clear that the bottle closure device as conceived can be subjected to numerous modifications and variants, all falling within the scope of the invention; furthermore, all details can be replaced by technically equivalent elements. In practice, the materials used, as well as the dimensions, may vary depending on the technical needs .
