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. A closing system for large and small bottles comprising a single piece that acts as a cap or closing, integrated by three parts: a cover, a screw and an elastic part, the cover and the screw are made of a rigid material and the elastic part is overpressed on the cover and the screw; the piece is manufactured using a food grade material: the cover covers an opening of the bottle, the cover has a narrowing of material at one of the diameters defining covering half fins, the covering half fins starting at a top of the cover and stem out from a neck that enters an opening of the bottle, inside the neck is an inner threaded hole and outside the neck is a lip that acts as a circular groove, the neck ends with an inverted tapered shape, an interior of the inner threaded hole is joined to the screw in an inverted position by a fine strip of material, to form a joint, the joint between the inner threaded hole and the screw will break when the screw is fastened inside the inner threaded hole of the neck: a drive shape on a head of the screw allows using a tool to fasten the screw to the inner threaded hole the head of the screw has a clamping line on the elastic part, the elastic part is overpressed on the cover and the screw from the lip to the clamping line, the elastic part has perimeter grooves so when the threaded part of the screw is inserted into the inner threaded hole in the neck, the elastic part is compressed and the screw attaches to the lip of the neck by the fastening ring which opens the perimeter grooves of the elastic part with a suction effect and the piece is attached to the walls of the neck of the bottle.

2. A method for opening the closing system for large and small bottles as described in claim 1 comprising the steps of: first, the covering half fins are folded so they lift up; second, the covering half fins are turned by hand in the opposite direction to the thread to decompress the elastic part so an unscrewing clearance is left; third, the piece is pulled up and the large or small bottle is opened.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) 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.

(2) FIG. 1.shows a cross-section of the piece with its different parts.

(3) FIG. 2.shows a plan view of the piece

(4) 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.

(5) 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.

(6) FIG. 5.shows a plan view of the piece with the covering half fins lifted.

(7) 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

(9) 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.

(10) 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).

(11) 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.

(12) 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.

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

(14) 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.

(15) 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).

(16) 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.

(17) 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.
