Description

The invention relates to the field of closures intended for closing vessels, usually bottles intended for storing alcoholic beverages, usually hard liquors, aperitifs, liquors. The invention mainly relates to the field of composite closures, so called because they are equipped with means complementary to the fixed assets of the “standard” closures, including, in particular, fasteners to the neck and sealing means. The invention relates, in particular, to screw closures containing a screw insert or screw element cooperating with a thread on the neck of a vessel.

From French patent FR 2802181, issued in the name of the Pechiney Emballage Alimentaire, the former name of the Applicant, a composite closure cap is known. This cap contains a plastic liner provided with a seal, a threaded skirt and a metal sheath covering the liner, as well as means for imparting weight and / or volume to the portion of the cap located above the gasket forming it with a tight seal.

The present invention is directed, like the capping caps of French patent FR 2802181, to provide the manufacturer of strong drinks, spirits and liquors with new means of capping these products using, in particular, a capping cap that functions as known capping caps, but, in addition to In addition, giving the opportunity to update the product in other aspects with the provision of new functionality. The present invention aims to solve the problems posed in the French patent FR 2802181, by other means than proposed in this patent. It is also aimed at offering many options for solving assigned tasks. Indeed, given the particular importance of brands in the trade in spirits, spirits and other liquors, it is desirable that each brand has its own specific closure cap, which would distinguish it from others.

In addition, the invention is directed to giving the closure caps an individual appearance that distinguishes them from traditional closure caps.

In accordance with the invention, a composite closure cap for sealing the neck of a bottle, typically an alcoholic beverage, includes a lower glass thickening and an external thread, wherein said composite closure cap has an axial height H and contains:

a) a metal closure cap equipped with a metal head and a metal skirt with a height Hc <H and an average diameter Dm, comprising a seaming zone for said metal closure cap usually around the neck of the bottle or around a part intended to be installed on said neck, and means for first easily opening said a composite closure cap, wherein the lower portion of said metal skirt remains connected to said neck when said composite closure cap c screwed with the first opening of said neck,

b) a liner of plastic material connected to the upper part of said closure metal cap, said liner comprising a head and a skirt with an internal thread with an axial height Hi <Hs,

c) at least one first outer part connected to said metal closure cap, said first outer part having at least one peripheral part with a diameter Dp> Dm for manual gripping in such a way that when the composite closure cap overlaps said neck, manual rotation of said outer part causes rotation of said metal closure cap and rotation of said liner, thereby providing screwing of said composite cap and opening said bottle,

and differs in that it also contains a second outer part connected to said metal skirt in order to close and mask the lower part of said metal closure cap.

The closures of the invention completely renew the appearance of traditional closures. They present with the first and second parts mentioned two additional substrates for applying any type of decor, which opens up great opportunities for distinguishing the proposed closures from traditional closures, adding to them the appearance or decor elements that are usually inherent in the highest quality bottle packaging.

Said composite closure cap comprises a metal closure cap, a part also called a “casing” consisting of a head and a metal skirt. A metal skirt is a zone, usually annular, of seaming the shell around the lower part of the annular protrusion of glassware, or seaming around the intermediate part, which is rigidly fixed to the neck, as an internal part, indicated by 81 and shown in Fig. 7 as an irreplaceable device.

According to the invention, said composite closure cap comprises a second outer part connected to a metal skirt of the sheath, the second part usually having a decorative pattern on its outer surface. Said second outer part may be formed in the form of a tubular cylindrical part of diameter Ds, the value of which lies between Dp and Dm, while the inner diameter of said cylindrical tubular part has a value usually close to Dm.

Said second outer part may also be articulated with the lower part of the metal skirt of the sheath so that said second outer part remains axially articulated with said lower part during said first opening of the aforementioned neck.

Said outer part can be rigidly axially connected to the metal skirt of the sheath, for example with its lower part, usually due to the adhesive layer, while its axial height Hs is at least 0.5 height H in the lower part of the sheath skirt so that cover most of the lower part during the capping operation. This fixed part is placed in such a way that it leaves free access to the seaming zone, usually an annular, mentioned metal skirt.

Said outer part may also be movable, which moves axially and which has two predetermined stable positions relative to said metal skirt due to the positioning means. These two positions have a lower position in which said movable part leaves free access to the gripping zone, usually an annular, metal skirt of the sheath, and an upper position in which said movable part axially raised in the direction of the first outer part after rolling at least masks the seaming zone of said metal skirt. When it is in the upper position, the said movable part interacts with the lower part of the metal skirt of the sheath in such a way as to remain in interaction with the specified neck after unscrewing the composite closure cap.

The positioning means used for the second upper movable part can axially interact with the axial locking means of said movable part with the axial locking means of the metal skirt. This positioning means may comprise or form reverse snapping means to provide a reverse transition from one position, upper or lower, to another position, respectively, lower or upper. This positioning means is designed in such a way that even when the second outer part is in the upper position, unscrewing said composite closure cap can be carried out, while said second outer part remains rigidly connected to the neck due to the axial locking means for the upper position. However, the axial locking means used for said lower position allows said second outer part to remain rigidly connected to the metal skirt of the sheath when the closure cap is not yet rolled over the neck. Preferably, said positioning means is designed so that the second outer part, after being lowered to facilitate access of the rolling tool to the rolling area of the metal skirt of the sheath, is set to the upper position and held locked in this upper position to block access to the rolled area.

In accordance with the invention, the second outer part may be made of a material selected from plastic materials, metals, metallized plastic. Preferably, it may contain at least one transparent zone, usually the upper transparent part, in order to show the line of weakening or the line of the jumper, as well as to make visible the first opening of the said neck.

Preferably, the closure cap of the invention comprises at least one first outer part connected to said metal closure cap by means of communication, said first outer part having at least one peripheral part for manual grip with an average diameter Dp > Dm with a ratio of Dp / Dm, typically between 1.1 and 1.5, wherein said average diameter Dp is the diameter of the axial surface, called the surface of the shell, covering said first outer tal so that when said composite closure cap closes said neck, manually rotating said outer part rotates said metal closure cap and rotates said liner, thereby ensuring that said composite closure cap is unscrewed and said neck opens.

Preferably, said first outer part is made of a material selected from the following list: metal, plastic material, glass, ceramic, refractory material, composite material, pressed or sintered material, or a combination of one or more of these materials; it may be an integral part formed by injection molding into a mold or processing and / or removal of material, said integral part comprises or forms a cavity for accommodating said upper part of said metal closure cap. This part may also be not integral, but made of the source material in the form of a tape or sheet, usually a metal source material by extrusion or sheet stamping. Preferably, said first outer part forms or comprises means for weighting the composite closure cap.

The peripheral part of said first outer part may have a cylindrical shell. But it can also to facilitate manual grip and rotation of the composite closure cap:

- be elongated along the main direction;

- contain many N-axial grooves or axial grooves with N ranging from 3 to 18, with an angular clearance of 360 ° / N;

- contain many N 'annular recesses or annular grooves with N' comprising from 1 to 10, placed at an equal distance along the axial direction.

Typically, said liner is rigidly connected to said metal closure cap by a layer of adhesive material, but it can also be rigidly connected to said closure cap by thermally pressing the skirt with the thread of said liner into the metal skirt of said metal closure cap, and at least said metal skirt said closure cap is coated from the inside with an inner layer of varnish or a thermoplastic material selected depending on the mentioned layer Cesky material of said insert and able to be pressed into said insert. Preferably, said inner layer of said metal closure cap comprises, in a separate state, the plastic material of said liner, the properties of which allow thermopressing said liner in said metal closure cap.

Typically, said first outer part is rigidly connected to said metal closure cap using a layer of adhesive material.

In a particular embodiment of the invention, the upper part of said metal skirt comprises a plurality of radial holes so that said liner and said first part can be thermally pressed through said many radial holes, all or part of said liner and said outer first part being of a chemical nature , allowing to carry out the mentioned thermal pressing.

Said liner made of plastic material preferably contains a gasket forming a corresponding part, rigidly connected to said liner and designed to provide a tight seal for the said neck. Since the neck of the bottle should be equipped with a pouring device or a device that prevents filling, said liner is preferably connected to the gasket. The insert contains, for example, a head made of plastic material, which includes at least one annular sponge interacting with said seal or said gasket to provide a tight seal for said neck.

In another embodiment, the metal skirt of the sheath comprises a shoulder forming an axial stop for said outer part, typically for the lower edge of said first upper part, said shoulder separating said metal skirt into an upper part of a smaller diameter and a lower part of a larger diameter.

In a large number of variants of the invention, said first outer part has a lower edge that tangentially connects to the metal skirt of the sheath in such a way that said lower edge and said metal skirt are connected without breaks and have, as a rule, the same diameter.

A composite closure cap according to the invention may comprise a device called a “pouring device” designed to facilitate the flow of said liquid, wherein said pouring device comprises a flexible annular sponge and can be movably connected to said composite closure cap, typically due to axial contact friction removing said liner and an inner skirt cooperating with the inside of said neck typically due to at least -stand annular rib for tight connection with said neck.

The composite closure cap of the invention may also comprise a device called an “excluding device” designed to prevent fraudulent filling of said bottle through said neck, wherein said excluding device is provided with reversible connection means with said integral closure cap so that the device to avoid fraudulent filling, it is fixed on the neck during the capping operation and remains rigidly fortified on the specified neck when screwing the composite closure cap. In a particular embodiment, this device may be non-reversibly mounted directly on the ring of a glass vessel. In this case, the external thread of the neck is not located on the ring of the glass vessel, but in the upper part of this device to exclude fraudulent filling irreversibly mounted on the neck, this upper part has a thread for additional screwing of the device onto the thread of the insert.

Depending on the type of decor, the above-mentioned external first (5) and second (6) parts were decorated either before joining or after joining when forming said closure cap (1).

Hereinafter, the example 3 shown in FIG. 5 will be described in detail 3, taking into account that this closure cap includes general features of the invention, which can be detailed and / or illustrated by other drawings.

The composite closure cap 1 of this embodiment comprises a pouring device 9 having in its upper part a flexible annular sponge 90 and an inner skirt 91 designed to be sealed with force in the neck 2 due to the plurality of ribs 910.

The composite closure cap 1 comprises a metal closure cap (or “sheath”) 3 provided with a metal skirt 31 having a seaming zone (36) of said metal closure cap around the neck (Fig. 5 shows a skirt 31 rolled up at position 36 'on the shoulder 210 of the lower parts of the annular protrusion 21), as well as the line of weakening 330, used as a means of first easy opening of the said composite closure cap.

The composite closure cap 1 comprises a liner 4 of plastic material rigidly connected to the upper part 32 of the sheath 3, said liner comprising a sealing head 40 and a skirt with an internal thread 41 ', in this case, especially thin with an axial height Hi <Hc.

The composite closure cap 1 comprises a first outer part 5 connected to a metal closure cap 3, which is a peripheral part 50 for manual gripping with an average diameter Dp> Dm, so that when said composite closure cap overlaps the neck, manual rotation of the said outer part leads to rotation a metal closure cap and the rotation of said liner, thereby providing for loosening said composite closure cap and opening said the neck.

The composite closure cap 1 comprises a second outer part 6 connected to the metal skirt 21 in such a way as to overlap and mask the lower portion 35 of said metal closure cap. This second outer part 6 is a movable part 61, which moves axially and has two predetermined stable positions relative to the metal skirt 31: the lower position, in which the movable part 61 leaves free access to the annular seaming zone of the metal sheath skirt, and the second upper position, in which said movable part 61 axially raised in the direction of the first outer part 5 after seaming, at least masking the seaming zone 36 'of said metal skirt. The movable part 61 in the upper position interacts with the lower part 35 of the metal skirt 31 of the sheath 3 in such a way as to remain on the neck 2 after unscrewing said composite closure cap 1.

The positioning means 18 used for the second outer movable part 61 axially interacts with the axial locking means 64 and 631 located on the movable part and the axial locking means 311 and 312 carried by the metal skirt 31. This positioning means can form a reversible snap means providing a reverse transition from one position, upper or lower, to another position, respectively, lower or upper. In this case, the positioning means 18 is made in such a way that said second movable outer part 61, after being held in the lower position to facilitate access by the rolling device to the seaming zone of the metal skirt of the sheath, is moved to the upper position and held locked in this upper position to prevent access to the zone seaming 36 '.

As shown in FIG. 5, the second outer part 61 is held in the upper position due to interaction with the axial locking means 64 and 311. It is held in the lower position due to interaction with the axial locking means 631 and 312. These axial locking means used in the lower position, allow said second outer part 61 to remain rigidly connected to the metal skirt 31 of the sheath 3 when the closure cap has not yet been rolled up on the neck. Figure 5 shows that the metal skirt 31 carries exactly under the seaming zone 36 or seaming zone 36 'the first metal ring 37, the two tilts of which 311 and 312 serve as a snap means, while the first tilt 311 in the upper position serves as an irreversible snap stop in the sponge 64 of the movable part 61, and the second 312 serves in the lower position as a stop for irreversibly snapping the inclined wall 631 extending from the upper edge of the said part 61.

Unscrewing the composite closure cap can be accomplished, with the first outer part 5 remaining connected to the upper part 32 of the sheath 3, and the second outer part 61 remaining connected to the lower part 35 of the metal skirt 31, which itself is connected to the lower part of the annular protrusion 21, onto which she rolled up.

The second outer part 61 is made of a polyolefin, typically polypropylene. It is not made transparent (metallization, varnishing, application of paint, etc.) in its upper part 63, since the latter is transparent and the line of weakening 330 can be seen when said external movable part 61 is in the upper position. In an embodiment, to improve the transparency of the upper part 63, the second outer part 61 is made of crystalline polystyrene. The upper part 63 is provided with annular ribs 630 to improve the manual grip of the second outer part 61.

The second outer part 61 must move a fairly large distance in order to reach its lower position in order to provide sufficiently wide access to the seaming zone so that the seaming rollers or other seaming devices can approach the shoulder 210 of the lower part of the annular protrusion 21 without affecting other parts closure cap. This distance is usually between 5 and 15 mm. As can be seen in FIG. 2c, the lower position may correspond to the installation of the lower outer edge 611 of the second outer part 61 on the neck of the bottle 2, which has a taper for this purpose. In this case, the second outer part 61, which is in the form of a cylinder, should have an inner diameter greater than 1 mm in diameter of the lower part 35 of the metal skirt 31. Preferably, said metal skirt 31 has a second ring 38, the radial height of which is 0.5 mm, which allows the second outer part 61 to move along the axis 10, while remaining centered.

The composite closure cap of Example 3 (FIG. 5) contains a pouring device 9 designed to facilitate fluid flow and which contains a flexible annular sponge 90, while it is rigidly and movably connected to the composite closure cap 1 by means of an insert 4 by axial friction force the periphery 45 of the outer ring 47, articulated with the liner 4. This pouring device 9 also contains a lower skirt 91 for interacting with the inner part of the neck 2 due to at least one annular rib at 910 tightly connects with a neck 2. In this case the edges 910 are represented schematically, "members" in the glass without upward angling.

On the closure cap of example 4 (figa-6c) is also placed a fixture 9 ', which also performs the function of a fixture to prevent pouring. It is also provided with a flexible annular sponge 90, which interacts with the liner 4. It also contains an inner skirt 91, which interacts with the inner surface of the neck 2 due to the plurality of annular ribs 910 that deform when inserted with the force of the device into the neck (Fig. 6a).

A tight seal is provided by the action of the annular sponge 470 of the outer ring 47, which causes the flexible annular sponge 90 to abut the thin portion 22 of the neck.

Composite closures in examples 4 and 5 (Fig.6 and 7) contain devices to prevent pouring 8 and 9 '.

Devices for the prevention of pouring 8 and 9 'are designed to prevent any unauthorized filling of the bottle through the neck 2. They are rigidly connected to the composite closure cap 1:

- the device 8 has a threaded part that allows it to be screwed onto the insert 4 (in this case, the screwing of the composite closure cap is no longer carried out on the glass ring: the external thread 20 'of the neck belongs to the device 8, which cannot be removed from the neck).

- the device 9 ', which also performs the function of a pouring device, as in Example 3, is connected to the liner 4 by means of a bevel of the contact creating friction along the axial periphery 45 of the ring 47, articulated with the liner 4.

These devices are installed in the neck 2 during the closure operation and remain connected to the neck when said closure composite cap 1 is unscrewed.

The device 8 to exclude the pouring of example 5 contains:

a) the upper part 80, containing a ring 800 with a thread interacting with the threaded skirt 41 of the liner 4;

b) a lower part 81 comprising an engaging skirt 810 cooperating with a lower part of the glass annular protrusion 21 and an inner wall forming a cavity 811 containing a lower hole 812;

c) a movable member 82, in this case a ball 820, capable of moving in said cavity for overlapping due to gravity of said lower hole 812, when said composite closure cap 1 is in a vertical position, forming an anti-return device.

In the aforementioned device 8 for excluding pouring:

a) said upper part 80 comprises an upper mesh 801,

b) said lower part 81 comprises a bulge 813 provided with side openings for fluid passage.
