CAPPING ASSEMBLY FOR RECEPTACLES

Abstract

The present invention belongs to the technical field of closures with discharge devices for receptacles, focusing on hinged closures. It consists of a capping assembly intended to be attached to the gland of a liquid container. This assembly consists of a tubular neck (1) and a cylindrical hinged cap (2). The cap integrates a ring (3) linked to the neck, a hinged lid (4) for opening and closing the pouring hole, a hinge (5) for hinging the cap and frangible bridges (16) between the ring and the cap. Additional elements in the tubular neck, such as a lower collar and an upper washer, contribute to the efficiency and functionality of the assembly.

PREFERRED EMBODIMENT OF THE INVENTION

[0028] A detailed explanation of an example of a preferred embodiment of the subject matter of the present invention is given below with the aid of the figures referred to above.

[0029] The capping assembly for receptacles described is intended to be attached to the gland of a receptacle containing liquids, in which the gland has a pouring orifice for the outlet of the liquid. This capping assembly consists of a neck (1) axially attachable to the gland of the receptacle, and a hinged cap (2), substantially cylindrical, attached to the neck (1) and comprising a ring (3) linked to the neck (1), a hinged lid (4) for opening and closing the pouring orifice and a hinge (5) for hinging the lid (4) with respect to the ring (3).

[0030] The neck (1), shown in detail in FIG. 7, is made up of a tubular body comprising a lower support collar (6), which protrudes radially outwards, and an upper locking washer (7), which also protrudes radially outwards and which is arranged axially between the lower collar (6) and the pouring orifice. The lower collar (6) delimits a support and lower stop for the ring (3) of the cap (2) and the upper washer (7) forms an upper stop for the ring (3), so that it is retained in the neck (1) between the lower collar (6) and the upper washer (7).

[0031] An intermediate cylindrical part (8) is arranged axially between the lower collar (6) and the upper washer (7). This cylindrical part (8) is intended to face an inner face of the ring (3) of the cap. The internal diameter of the neck (1) is at its smallest at the height of its cylindrical part (8).

[0032] The cylindrical part (8) has a height (h), bounded between the lower collar (6) and the upper washer (7). The height (h) has a value in the range from 3.3 mm to 4 mm, including the upper and lower extreme values of this range.

[0033] The ring (3) of the cap (2) includes gripping means for its retention on the neck (1). The lid (4) comprises an upper base (9), flat and disc-shaped, joined to a curved perimeter wall (10) that extends from the lower part of the upper base (9). From an upper section of said perimeter wall (10) extends a transverse visor (11), designed to allow easy manual opening of the cap (2), as shown in FIGS. 2 and 3.

[0034] In accordance with the present invention, the visor (11) comprises a flap transverse thereto and in correspondence with a complementary recess provided in the upper edge of the ring (3). Furthermore, the flap comprises on the edge of its inner surface a cord arranged transversally to the axial axis of the cap (2) to effect the gripping of the lid (4) to the neck (1).

[0035] In this preferred embodiment, the upper base (9) comprises a cylindrical skirt (12) emerging from its inner face and sized for insertion inside the neck (1), as shown in FIG. 7.

[0036] FIG. 3 shows the back of the cap (2), where the hinge (5) that articulates the lid 4) with the ring (3) is located. As can be seen, on the perimeter wall (10) there are two pairs of vertical slits (13), arranged parallel to the axial axis of the cap (2), defining the formation of two flexible strips (14) connecting the two parts (3,4). The ring (3) may comprise a projection (15) arranged between the strips (14).

[0037] The ring (3) is, before the first opening of the cap cap (2), connected to the lid (4) by frangible bridges (16) intended to be broken by traction at this first opening as shown in FIG. 2. These frangible bridges (16) thus constitute tamper-evident seals and connect the upper edge of the ring (3) and a lower edge of the perimeter wall (10).

[0038] When the frangible bridges (16) break, the ring (3) is slightly separated from the lid (4), to which it is held together only by the hinge (5) as shown in FIGS. 4 and 5.

[0039] Due to the height of the cylindrical part (8) of the neck (1), which is higher than usual in this type of capping assembly, the gap between the ring (3) and the cap (2), once the frangible bridges (16) have been broken, is also higher than usual, thus generating a strip that leaves the surface of the cylindrical part (8) of the neck (1) partially exposed, as illustrated in FIG. 3. This generates evidence that makes it easy and quick to see that a first opening of the cap (2) has undoubtedly taken place.
