CLOSING SYSTEM FOR BOTTLES AND SMALL BOTTLES AND METHOD FOR THE USE THEREOF FOR THE OPENING OF SAID BOTTLES

Abstract

Closing system for bottles and small bottles and method for the use thereof for the opening of said bottles integrated by a single piece with three differentiated parts, two of them, inner threaded hole and screw (7), made of rigid material and joined by a pre-cut line, used as a base on which an elastic part (10) is overpressed. This elastic part (10) has some perimeter grooves (18) that, when fastening the screw (11) in the inner threaded hole (4) of the neck (3), presses the elastic part (10) and secures it against the walls of the bottleneck (3). The bottle can be opened by just lifting the covering half fins (9) and turning them in the opposite direction to the thread, so the elastic part (10) is decompressed and can be easily removed, leaving the bottle opened. All materials are food grade materials.

Claims

1. Closing system for large and small bottles with the particularity of being a single piece that acts as a cap or closing, integrated by three parts: a cover (1), a screw (11) and an elastic part (10). The first two are made of a rigid material and the third one overpressed on them; all of them are manufactured using a food grade material: the cover (1) covers the opening of the bottle and it (1) has a narrowing of the material (2) at one of the diameters defining some covering half fins (9) that, starting at the top of the cover (1) stem out from the neck (3) that enters the bottle opening. Inside this neck (3) there is an inner threaded hole (4) and outside there is a lip (5) that acts as a circular groove. The neck (3) ends with an inverted tapered shape (6). The interior of the inner threaded hole (4) is joined to the screw part (11) in an inverted position by a fine strip of material. This joint between the inner threaded hole and the screw will break when the screw (11) is fastened inside the inner threaded hole (4) of the neck (3): the screw has a drive shape (8) on its head that allows using a tool to fasten the screw (11) to the inner threaded hole (4). In addition, the head of the screw (13) has a clamping line (15) on the elastic part (10). the elastic part (10) is overpressed on the cover (1) and the screw (11) from the lip (5) to the clamping line (15) and it has some perimeter grooves (18) so when the threaded part of the screw (11) is inserted into the inner threaded hole (4) in the neck (3), the elastic part is compressed (10) and it attaches to the lip (5) of the neck (3) by the fastening ring (18). This opens the grooves of the elastic part with a suction effect (12) and the piece is attached to the walls of the bottleneck.

2. Operating instructions for opening large and small bottles as described in the first patent claim with the particularity that the opening occurs in three steps: first, the cover semi-fins (9) are folded so they lift up; second, the covering half fins (9) are turned by hand in the opposite direction to the thread to decompress the elastic part (10) so an unscrewing clearance (17) is left; third, the entire piece is pulled up and the large or small bottle can be opened without difficulty.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to understand the scope of the features and advantages of the purpose of the invention, the object, application and brief include six drawings that complement the description of a preferred execution mode that will be carried out next, the content of which is not limiting but merely illustrative.

[0021] FIG. 1.—shows a cross-section of the piece with its different parts.

[0022] FIG. 2.—shows a plan view of the piece

[0023] FIG. 3.—shows the screw part screwed in the threaded hole part and pressing the elastic part. The figure also includes a cross-section of the set.

[0024] FIG. 4.—shows a cross-section of the screw part fastened to the threaded hole part pressing the elastic part and the covering half fins already lifted to facilitate unfastening the screw and opening the bottle.

[0025] FIG. 5.—shows a plan view of the piece with the covering half fins lifted.

[0026] FIG. 6.—shows the cap piece already extracted from the bottle and it shows a cross-section of the screw partially unscrewed and the decompressed elastic part.

DESCRIPTION OF A PREFERRED EXECUTION MODE

[0052] FIG. 1. The cover (1) has a narrowing of the material (2) that will act as a hinge, pivoting over the neck (3) that has an inner threaded hole (4) inside.

[0053] On the outer cylindrical surface of the neck (3) a lip (5) can be noticed that acts as a groove. Said neck (3) ends in an inverted tapered shape (8).

[0054] This part of the closing system piece shows a kind of circular section, joining the inner threaded hole and the screw, and it is very thin, so it can be cut, releasing both parts, cover and screw, in order to fasten them together. This break occurs when the fastening starts.

[0055] FIG. 2. The fastening is completed using a flat head screw driver or similar tool, introduced into the drive shape (8) in an inverted position, that is, with the head below, holding the covering half fins (9) in their position.

[0056] FIG. 3. When fastening the screw into the inner threaded hole, the elastic part (10) is compressed and stays like this.

[0057] When this occurs, the grooves with suction effect (12) attach this part to the walls of the bottleneck. The element pressing the screw (11) against the inner threaded hole (4) is the screw head (13) with a tapered shape and this facilitates pushing out the elastic part (10) towards the bottleneck.

[0058] FIG. 4. The screw thread (14) matches that of the inner threaded whole (4) and the clamping line (15) of the screw head (13) so it allows choking and securing the compressed elastic part (10) to stop the pressure of the liquid contained from opening the bottle. The elastic part (10) is secured against the neck (3) by the fastening ring (18) of the elastic part (10) inserted into the lip (5).

[0059] FIG. 5. To unscrew the piece and open the bottle, the covering half fins (9) must be lifted, so the thumb and index fingers can hold them and turn them in the opposite direction of the thread, opening the bottle.

[0060] FIG. 6. When the cap has been released, there will be an unscrewing clearance (17) that allows decompressing the elastic part (10), so the perimeter grooves (18) have no pressure and the part recovers the original diameter. Then, it can be removed from the bottle.
