Description

Waterproof screw cap for wine bottles and closure method with said cap.

Object of the invention

The present invention relates to a plug sealed thread for wine bottles that allows a better wine conservation and, therefore, a decrease in the number of bottles to be discarded, as it provides a tightness total, unlike other plugs.

The screw cap is comprised of an outer body or capsule, a threaded inner body and a deformable disk inside the threaded body
fallen

Characterize the plug that the distance between Thread steaks lead to a game that allows the vertical displacement of the cap relative to the bottle, which at its It also allows the compression of the inner body to decrease deformable disc and that together with a lower retention means of the vertical descent ensures this deformable disk compression and therefore the tightness of the plug.

Background of the invention

The traditional plugs of Cork sausages in the neck of the bottle. These plugs, without However, they may have the following disadvantages: wine cork, leaks, dust or debris, drilled plugs or plugs that sink when the corkscrew is inserted.

Mixed plugs are also known Cork-plastic that solve some of the Disadvantages listed above, but still present lacks Reference is made to the patent with number of publication ES 2074856 "Usable composition for manufacture of plugs and their manufacturing procedure "which refers to an agglomerated cork composition consisting of cork particles and a binder or glue that improves the properties physical of this type of plugs, such as lack of elasticity and the low gas permeability of wine. The recommended plug It is characterized in that the plastic material is constituted by microspheres and has a closed honeycomb structure, the alveoli containing an expanding fluid.

There are also caps composed of following three elements: an outer material capsule metallic, a threaded inner body of plastic material and a Expanded polyethylene disc internal to the outer capsule. Be EP patents are mentioned as background of this type of plugs 1201553 "Waterproof metal plug with inner body plastic "and WO2005012126" Enhanced capping capsules and manufacturing procedure. "These plugs achieve a greater tightness and better preservation of liquors than Traditional plugs described above.

The conservation characteristics and the maintenance of the wine in perfect hygienic conditions for the consumption are guaranteed by the cap described in this invention, by presenting a plug and a closure method that improves notably the tightness.

The recommended cap is formed by a outer capsule of metallic material, a threaded inner body of plastic material and a deformable disk inside the threaded body and is characterized because the distance between fillets of the thread gives rise to a game that allows the displacement vertical cap with respect to the bottle, which in turn allows for lowering of the inner body the deformable disc compression and which together with a lower retention means of vertical descent this compression of the deformable disc is ensured and therefore the plug tightness.

Description of the invention

The present invention consists of a plug sealed thread for wine bottles, which allows a better content conservation

The plug consists of at least three parts, an outer body or capsule, a threaded inner body and a deformable disk located inside the cap and in its upper part.

The outer capsule is metallic, preferably  Aluminum and can be decorated.

The deformable disk is manufactured in expanded polyethylene and the face that is in contact with the liquid  It is covered with a film that increases its tightness.

The threaded inner body is made of plastic material, preferably high density polyethylene. The initial outer diameter of the threaded body is larger than the internal diameter of the metal capsule setting both pieces a degree of tightening that prevents them from rotating with each other.

The thread of the bottle allows a game between consecutive fillets, that is, a fillet of the cap can support, either, at the bottom of a bottle steak, or, in the top of the steak immediately below, but not simultaneously on both steaks.

As a summary it can be stated that the plug is defined because the distance between fillets of the thread gives place to a game that allows the vertical movement of the cap regarding the bottle, which in turn allows for lowering of the inner body the compression of the deformable disc and that together with a lower retention means of the vertical descent ensures this deformable disk compression and therefore the tightness of the cap.

The closure of the cap would occur at least the following stages:

\ sqbullet

Cap Threading

\ sqbullet

By plug pressure against the bottle, its descent is forced thanks to the game of thread fillets described above. On the disk occurs a deformation due to the partial insertion of the neck of the bottle, which ensures the tightness of the cap.

\ sqbullet

Lower retention of the capsule at the bottom of the shoulder of the bottle neck, by notching maintaining deformable disc compression, which guarantees the fixation of the cap.

For the opening of the bottle a cut in the capsule with attachment points, which will break when performing the opening operation by unscrewing, so it would not be it is necessary to use a cutting instrument to perform the uncapped from the bottle.

Another possibility for opening the bottle is the realization of a weakening line, proceeding after cutting the capsule with a suitable instrument, which allows unscrewing it. This process of uncapping the bottle allows you to enjoy the ritual of the Opening a bottle of wine.

Either of the two previous systems ensures the impossibility of refilling the bottle, since the Capsule would reveal that it has been previously opened.

Detailed presentation of an embodiment

The present invention consists of a plug sealed thread for wine bottles, which allows a better content conservation

The plug according to this particular example is formed by at least three pieces, an outer body or capsule (1), a threaded inner body (2) in PE and a deformable disk (3) located inside the cap and on top.

The outer capsule (1) is metallic, preferably aluminum and can be decorated.

The deformable disk (3) is made of expanded polyethylene, the face being in contact with the liquid (3.1) coated with a film that increases its tightness

The threaded inner body (2) is manufactured in  plastic material, preferably high polyethylene density.

The initial outside diameter of the threaded body (2) is larger than the inner diameter of the metal capsule (1) establishing both pieces (1, 2) a degree of tightening that prevents turn each other.

The thread (2.1, 4.1) allows a play between consecutive fillets, so a fillet (2.1.1) of the plug (2) can support, or at the bottom of a steak (4.1.1) of the bottle (4) or on the top of the steak immediately lower (4.1.2) depending on whether the plug is found without being pressed down, see figure 1, or with this pressure, see figure 2, moving the cap vertically between these two ends with respect to the bottle (4).

By pressing the cap against the bottle (4) the deformable disc (3) supports compressions combined with possible push-ups In closing situation the deformable disk (3) supports a circular compression strain due to pressure exerted by the edge of the mouth of the bottle (4.3), a perimeter compression deformation caused by the pressure that exerts the disc (3) on the upper wall of the threaded element (2) and a partial flexion in the perimeter zone. These compressions  and deformations of the deformable disc (3) in conjunction with the means of Bottom retention ensure the tightness of the cap.

The lower retention means consists of a notch (1.1) made in the capsule (1) intended to remain immediately below the shoulder (4.4) of the neck of the bottle on which it rests.

In this preferred example the opening of the cap  threading is done, or, through a cut with points of union practiced in the capsule (1) in the lower part of the body (2), or, through a line of weakening and subsequently cutting with a suitable element.

The closing process of the cap is carried out at  less, the following stages:

First stage, screw capping;

Second stage, by pressing on it and thanks to the thread fillet set (2.1, 4.1), its decrease with respect to the bottle (4) forcing the compression of the deformable disc (3) and partial penetration of the edge of the mouth of the bottle (4.3) in it (3).

Third stage, lower fixation or retention of the capsule (1) of the cap by compressing the disc deformable (3).

The vertical displacement of the fillets of plug thread (2.1.1) is made using the set of the thread (2.1, 4.1) from the bottom of the fillets of the bottle (4.1.1) to the top of the steak immediately Bottom of the bottle (4.1.2), in this way the deformation of the disc (3) located between the edge of the mouth of the bottle (4.3) and the bottom of the cap (2).

The notch (1.1) is made by pressure, preferably by means of a rulinado of the capsule (1) in the part bottom of the shoulder (4.4) of the bottle neck (4).

The bottle opening operation is produced by unscrewing overcoming the resistance of a cut with junction points practiced in the capsule (1) in the lower area of the body (2), which makes unnecessary the use of an instrument of cutting to unclog the bottle.

Another opening option is by cutting the capsule (1) with a suitable instrument above the protrusion (4.4) of the bottle (4) where a line has previously been made of weakening, which allows the subsequent unscrewing of the plug. Cutting with the right instrument also allows Enjoy the ritual of opening a bottle of wine.

Both systems ensure the impossibility of refilling the bottle, since the capsule (1) would reveal that it has been previously opened

During the cap unscrewing maneuver, the disc (3) is attached to the upper part of the neck (4.3) of the bottle while the threaded body (2) rotates and rises, until circular projections (2.2) of the piece (2) drag the disc (3) by detaching it from the neck (4.3) of the bottle.
