SELF-EXTRACTING CAP

Abstract

The invention relates to a self-extracting stopper which can be accommodated inside the neck of the bottle, and which does not require a corkscrew or any other tool for the extraction thereof, formed by an assembly of parts preferably made of a plastic material and which, once assembled, permit a bottle or container to be stoppered. The face of the drum (8) and the surface of revolution of the flexible cylinder (4) can also carry marks that are engraved or in shallow relief. In this way, the assembly of the self-extracting stopper is formed by six elements and a cork cover (1), a nut (2), a flexible cylinder (5), a drum (8), a screw (12) and a wing nut (15), all of which are disposed and assembled according to their axial geometry, and which permit a method and process to be provided whereby bottles and/or containers can be stoppered or opened manually or automatically, and said self-extracting stopper being reusable.

Claims

1. Self-extracting cap consisting of a set of parts and sealed in the base by a cork cover (1) on the nut (2) and between it and the drum (8) integrate the flexible cylinder (5) of the screw (12) which rotates by turning and fastening the wing nut (15). The cork cover (1) is welded to the nut (2). The nut (2) has fins (3) attached to the neck of the nut (4). The flexible cylinder (5) has an axial inner hole and on both sides, nut (2) and drum wings fittings (7). The drum (8) has anti-rotation fittings (9) on its side, and wings on the back incorporated radially on the drum guide neck (6), which is aligned with the drum hole (10) around which the tread area of the male screw is located. The screw (12) has a section of coils with grooves (13), another section of a flat and cylindrical male (14), which ends in a square head (16); in turn, with a square hole of the inner screw (19). The wing nut has wing nut fins (17), a squared wing nut fitting (18) and a tab (20) run inside and along its axis to withdraw it from the bottle and, or, container.

2. Self-extracting cap in accordance with the above patent claim, with the particularity that the cork cover (1) may or may not be perforated in its central part, so the oxygen may or may not get inside the bottle and/or container.

3. Self-extracting cap according to patent claim 1, with the particularity that the drum guide neck (6) embraces the neck of the nut (4) allowing it to slide up and down the axial direction but preventing rotation.

4. Self-extracting cap according to patent claim 1, with the particularity that the flexible cylinder (5), when pressed between the nut (2) and the drum (8), expands towards the walls of the bottleneck and, or, container, putting pressure on them.

5. Self-extracting cap according to patent claim 1, with the particularity that the screw (12) is screwed onto the nut (4) by turning it to the right and by means of the wing nut (15) axially along its entire length, it has a wing nut fitting (18) which rotates the screw (12) on its square head (16).

6. Self-extracting cap according to patent claim 1, with the particularity that the wing nut (15) slides on the screw (12) thus having at least two positions: one lowered to the male height (14) in the transport position of the bottle and/or container AND two, sliding to the top so that the wing nut fins (17) are left outside the neck and rotate out of the neck so it can be opened by decompressing the flexible cylinder (59) by turning the screw (12) counter-clockwise.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to understand the range of features and advantages of the purpose of the invention, the model, application and brief includes a drawing that complements the description of a preferred mode of execution that will be carried out next, the content of which is not limiting but merely illustrative.

[0017] FIG. 1 shows the entire set, and the inner lines of the parts in the hidden devices are shown using slides.

DESCRIPTION OF PREFERRED MODE OF EXECUTION

[0039] FIG. 1. The self-extracting cap is sealed on the side touching the liquid, with a cork cover (1) welded to the nut (2) which has radially distributed anti-rotation fins (3) resting on the neck of the nut (4).

[0040] The flexible cylinder (5) has holes for the nut (2) fins (3) to prevent the nut from rotating when introducing the screw (12).

[0041] The flexible cylinder (5) is axially perforated to allow the drum guide neck (6) and its wings into the drum wings' fittings (7).

[0042] The drum (8) has two opposing anti-rotation fittings (9) to prevent the drum (8) from rotating when the flexible cylinder (5) expands inside the bottleneck.

[0043] In turn, the drum (8) has a central hole, drum hole (10) for the screw to get through (12) and around the drum hole (10) there is a tread area, tread area of the male screw (14) where it rests and the whole screw does not get through, (12) thus causing the nut (2) to compress the flexible cylinder (5).

[0044] The screw (12) in turn has grooves in its coils, (13) and on the series of coils, a cylindrical male (14) which ends in a hollow square head (16) with screw square hollow (19).

[0045] The wing nut (15) equipped with protrusions, fins of the wing nut (17) upon which to rest the fingers: thumb and index and make it turn, has a square shaped hollow inside it, as a squared wing nut fitting (18) for the square head (16) of the screw, which extends along the entire wing nut (15).
