Abstract

Closure device for bottles (50) comprising a pouring spout (14) capturable to the mouth of the bottle (50) and having an upper portion (15) equipped with an external thread (16) and a lower portion (18), a stopper (11) having a lateral portion (13) internally equipped with a thread (17) for engaging with the external thread (16) of the upper portion (15) of the pouring spout (14), a cylindrical sleeve (20) for covering the lower portion (18) of the pouring spout (14), and an annular removable lug (19), wherein the cylindrical sleeve (20) is both capturable to rotate and to come off with respect to the pouring spout (14), the annular removable lug (19) being provided between the stopper (11) and the cylindrical sleeve (20) so that, before the first opening of the closure device, the sleeve (20) is integral with the stopper (11) preventing its rotation. The removable lug (19) is in the shape of a ring extending along the entire circumference of the closure and is delimited by a first upper rupture line (21) connected to the plug (11) and by a lower rupture line (22) connected to the sleeve (20). The sleeve (20) comprises a first upper abutment portion (28) for engaging with a seat formed in the pouring spout (14) at the neck of the bottle (50) and a second lower abutment portion (29) for housing the lower (22, 29) edge of the pouring spout (14).

Description

Closure device for bottles with easily removable safety lugs

Technical Field

The present invention relates to a closure device for bottles equipped with an easily removable safety lug.

Background

Several closures for bottles are currently known, generally consisting of a stopper and a pouring spout. Such closure devices are described, for example, in documents WO 99/21773 a1 and GB 2418910 a.

The stopper has an internal thread adapted to engage a corresponding thread provided on the outer surface of the pouring spout to open or close the bottle. The latter being pressure-fixed into an opening in the neck of the bottle or connected to the neck of the bottle by known means.

Furthermore, the stopper is usually connected downwards to a sleeve for covering the pouring opening, to which sleeve the stopper is also rotationally constrained. The connection between the sleeve and the plug is usually achieved by means of an annular rupture line or by means of a removable lug element.

The removable lug arrangement also has the advantage of providing evidence of the first opening of the bottle. However, a simple rupture line does not itself provide a striking visual evidence of the first opening of the bottle, with the advantage that no manual operation is required before the stopper is grasped. Accordingly, manufacturers strive to design lugs that are easily removable.

Disclosure of Invention

Starting from such prior art, the object of the present invention is to provide an alternative closure device to the known closure devices which can be easily opened, although the known closure devices are of the type with removable lugs.

This and other objects according to the present invention are achieved by providing a bottle with a convenient opening with a closure device as described below.

Further features of the closure for bottles with a convenient opening are described in the following detailed disclosure.

Detailed Description

With reference to the figures, the reference numeral 10 indicates a closure device for bottles according to the invention. Such a closure device 10 for a bottle 50 comprises:

a pouring spout 14, in single or multiple pieces, which pouring spout 14 will be confined to the mouth of the bottle and has an upper portion 15 equipped with an external thread 16;

a stopper 11 having a lateral portion 13, the lateral portion 13 being provided on its inner portion with a thread 17 for engaging with an external thread 16 of the pouring spout 14;

a cylindrical sleeve 20 covering the lower portion 18, wherein the cylindrical sleeve 20 is constrained both to rotate and to come off with respect to the pouring spout 14; and

a removable lug 19 arranged between the plug 11 and the cylindrical sleeve 20.

In this way, before the first opening of the closure 10, the sleeve 20 is integrated with the stopper 11 by means of the removable lug 19, preventing the rotation of this stopper 11. As shown in fig. 2, the plug 11 may be removed only after the lug 19 is removed.

FIG. 4 also shows an internal pour spout and valve, however in the embodiment of FIG. 8 the device 10 contains only a single pour spout that includes both an internal pour spout and an external pour spout.

According to the invention, the removable lug 19 is in the shape of a ring extending along the entire circumference of the closure device 10. The removable lug 19 is delimited by a first upper rupture line 21 connected to the plug 11 and by a lower rupture line 22 connected to the sleeve 20.

The removable lug 19 also comprises a horizontal clamping portion 23 disposed between the upper 21 and lower 22 fracture lines. In particular, the horizontal clamping portion 23 is housed in a seat formed in the removable lug 19 and faces a lowered portion 24 for supporting the clamping.

The upper 21 and lower 22 fracture lines are equipped with horizontal splits 25 for assisting in the removal of the removable lugs 19 and may be made by means of bridge abutments 30 or from sections of reduced cross-section. Preferably, the horizontal clamping portion 23 has a knurled surface for supporting clamping.

Sleeve 20 comprises a first upper abutment portion 28 for connection with a seat formed in pouring spout 14 at the neck of bottle 50. The sleeve 20 further comprises a second lower abutment portion 29 for receiving the lower edge of the pouring spout 14. Due to these upper 28 and lower 29 abutment portions, the sleeve is restricted from being removed relative to the pouring spout 14.

Furthermore, the relative rotation is prevented by means of a series of

inclined teeth

31 and 32 obtained inside the sleeve 20 and directed outwards to the pouring spout 14.

In the embodiment of fig. 9-11, the horizontal clamping portion 23 of the removable lug 19 is equipped with at least one spacer element 33 on its rear surface, i.e. the surface facing the pouring spout 14 in the assembled configuration of the closure device 10. As shown in fig. 10 and 11, the spacer element 33 is configured to abut the upper portion 15 of the pouring spout 14 to maintain the horizontal clamping portion 23 of the removable lug 19 in a protruding position with respect to the lateral surface of the sleeve 20. In this manner, the user can easily grasp the horizontal gripping portion 23 in conjunction with the knurled surface for supporting the grip or the removable lugs 19 in addition to the knurled surface for supporting the grip.

It has thus been seen that the closure device according to the present invention achieves the objects described above.

The closure device of the invention is therefore conceived to be susceptible of numerous modifications and variants, all belonging to the same inventive concept; moreover, all the details may be replaced with technically equivalent elements. In this implementation, the materials used, as well as their dimensions, may be any according to technical requirements.
