Description

The present invention refers to an anti-theft and safety mechanism for bottles.

Anti-theft mechanisms are known, typically with a magnetic operation, adapted to contain therein objects offered for sales, such as compact discs, DVDs, musicassettes, videocassettes and the like, or applied outside various items, such as, for example, glasses and clothes.

These mechanisms are typically activated on the product to be protected, when this latter one is exhibited for its sale, and are removed, generally through suitable magnetic or electromagnetic devices, upon the payment of the product itself.

However, such known mechanisms still have some inconveniences, one of which being that they can be removed relatively easily and with unspecialized tools, to be inserted between the mechanism itself and the neck of a bottle, for example, in order to disconnect the locking mechanism.

Documents US-A1-2012/152883 and CN-U-203 499 390 disclose anti-theft and safety mechanisms for bottles according to the preamble of claim 1.

Therefore, object of the present invention is solving the above prior art problems, by providing an anti-theft and safety mechanism, which allows obtaining a strong amount of safety against the unauthorized removal with respect to prior art mechanisms.

Another object of the present invention is providing an anti-theft and safety mechanism for bottles which can be applied, in an extremely simple and quick way, also with a single hand.

The above and other objects and advantages of the invention, as will result from the following description, are obtained with an anti-theft and safety mechanism for bottles, in compliance with claim 1, of the type comprising a case and first locking and unlocking means of such mechanism, contained inside the case, these first locking and unlocking means being adapted to be magnetically attracted by external magnetic or electromagnetic means to the case for unlocking the mechanism, wherein the first locking and unlocking means are adapted to be actuated, when locking, with the simple insertion of the mechanism on the neck of the bottle, second locking and unlocking means being provided, which are adapted to be actuated, when locking, through a manual action, after such mechanism has been inserted on the neck of the bottle and, when unlocking, as consequence of the unlocking action exerted with the magnetic or electromagnetic means on the first locking and unlocking means, so that the only application of the external magnetic or electromagnetic means generates the complete unlocking of the first and second locking and unlocking means, allowing the removal of the mechanism from the bottle neck.

Preferred embodiment and non-trivial variations of the present invention are the subject matter of the dependent claims.

It is intended that all enclosed claims are an integral part of the present description.

It will be immediately obvious that numerous variations and modifications (for example related to shape, sizes, arrangements and parts with equivalent functionality) could be made to what is described, without departing from the scope of the invention, as will appear from the enclosed claims.

The present invention will be better described by some preferred embodiments thereof, provided as a non-limiting example, with reference to the enclosed drawings, in which:

FIG. 1 is a perspective view of an anti-theft and safety mechanism for bottles according to the present invention;

FIG. 2 is an exploded perspective view of the anti-theft and safety mechanism for bottles of FIG. 1;

FIGS. 3 and 4 are two sectional views of the anti-theft and safety mechanism for bottles according to the present invention;

FIGS. 5, 6 and 7 show the insertion and locking procedure for a bottle through the mechanism according to the present invention; and

FIG. 8 shows a sectional view of the anti-theft and safety mechanism for bottles according to the present invention in its unlocking position.

With reference to FIGS. 1 and 2, reference number 1 designates a preferred, but not limiting, embodiment of an anti-theft and safety mechanism for bottles, according to the invention.

With reference to the preferred embodiment shown in the Figures, the mechanism 1 substantially comprises a case 2 inside which first locking and unlocking means 3 and second locking and unlocking means 4 are contained.

The first locking and unlocking means 3 are adapted to be actuated, when locking, with the simple insertion of the mechanism 1 on the neck of the bottle and, when unlocking, through an action exerted from outside, with magnetic or electromagnetic means.

The second locking and unlocking means 4 are adapted to be actuated, when locking, through a manual action, after the mechanism 1 has been inserted on the neck of the bottle, and, when unlocking, as consequence of the unlocking action exerted with the magnetic or electromagnetic means on said first locking and unlocking means 3.

The first locking and unlocking means 3 comprise a hook 5, sliding on guides 6 obtained in a support 2a which is inserted into the case 2. The hook 5 is subjected to the action of elastic means, for example a helical spring 7, which counteract the backward movement of such hook 5 when a thrust is exerted onto the tip of the hook 5, as will be better described below. On the back of the hook 5 an element 8 made of ferromagnetic material, fr example iron, is made integral, which element 8, subjected to the action of magnetic or electromagnetic means of a known type (not shown), makes the hook 5 move backward, winning the reaction of the helical spring 7.

In order to allow an easy sliding of the hook 5 due to the thrust of the collar 10 of the bottle 9, it is preferable that the sliding of the hook 5 occurs on a plane comprising the axis of the neck of the bottle 9 and is slanted by an angle of about 45° with respect to the axis of the neck of the bottle 9.

The second locking and unlocking means 4 comprise a first half-circular element 11, integral with a push-button 12 which is inserted into an opening 13 made on the case 2. The first half-circular element 11 is sliding on guides 14 obtained in the support 2a inserted in the case 2 and is subjected to the action of elastic means which counteract its backward movement, for example two helical springs 15. A toothing is obtained on a side of the push-button 12, which toothing engages a corresponding toothing obtained on an element 16, sliding transversally to said push-button 12 and subjected to the action of elastic means, for example a helical spring 17. The shape of the tooth is such as to allow the sliding of the push-button due to a thrust applied in order to push it towards the neck of the bottle 9, but to prevent its return due to the only reaction of the helical springs 15.

The element 16 is shaped in such a way that, when the hook 5 moves backward due to the action exerted thereon by the ferromagnetic element 8, subjected to the action of magnetic or electromagnetic unlocking means, the element 16 moves away from the push-button 12, winning the reaction of the helical spring 17, thereby unlocking the push-button 12.

According to a preferred embodiment, the use of a second half-circular element 18 is provided, sliding substantially together with the first half-circular element 11 and, therefore, adapted to be actuated through the push-button 12, but further sliding axially with respect to said push-button 12 and subjected to the action of elastic means, for example a helical spring 19 which tends to compress it against the neck of the bottle 9.

For a correct operation of the semi-circular element 11, actuated by the push-button 12, it is advisable that the sliding axis is perpendicular with the neck of the bottle 9. Moreover, for a correct operation of the push-button 12 itself as regards the toothed element 16, it is advisable that the sliding direction of the toothed element 16 and the sliding direction of the push-button 12 are coplanar. Definitely, for the correct operation of the whole mechanism, it is advisable that the sliding directions of all elements and the axis of the neck of the bottle 9 are coplanar.

In practice, as shown in FIGS. 5 and 6, the anti-theft and safety mechanism 1 is inserted on the neck of a bottle 9 till a collar 10 of the bottle 9 presses on the hook 5 and makes it move backwards, winning the reaction of the helical spring 7. When the collar 10 of the bottle 9 has passed the tip of the hook 5, this latter one, pushed by the helical spring 7, again advances in order to block the neck of the bottle 9 inside the anti-theft and safety mechanism 1. Afterwards (as shown in particular in FIG. 7), by exerting a pressure onto the push-button 12, the half-circular elements 11 and 18 are taken in contact with the neck of the bottle 9, preventing the access to the tip of the hook 5.

By acting with magnetic or electromagnetic means on the ferromagnetic element 8 (as shown in particular in FIG. 8), the hook 5 moves backwards winning the reaction of the helical spring 7, interacts with the toothed element 16 which, by winning the reaction of the helical spring 17, unlocks the push-button 12 and the bottle 9 can be extracted.

Finally, in order to make the anti-theft action efficient, inside the case 2 at least one detecting system is advantageously placed, of the radiofrequency (RF), electromagnetic (EM) or acoustic-magnetic (AM) type with a ferrite core (not shown) or their combinations, cooperating with the anti-theft detecting barriers and/or at least one RFID element (not shown), according to the prior art.

The operation of the anti-theft and safety mechanism 1 of the invention will now be described, which is applied according to the following procedure:

• • placing the mechanism 1 on the neck of the bottle 9;
  • inserting the mechanism 1 on the neck of the bottle 9 till the hook 5 has passed the collar 10, thereby blocking the neck of the bottle 9 inside the case 2 of the mechanism 1;
  • sliding the push-button 12 towards the neck of the bottle so that the first half-circular element 11, and the second half-circular element 18, if present, are compressed against the neck of the bottle 9, such half-circular elements remaining pressed against the neck of the bottle 9 for engagement of the toothing of the side of the push-button 12 in the toothing of the toothed element 16.

As can be noted, the whole operation of application of the mechanism 1 to the neck of the bottle 9 can be performed by grasping the mechanism 1 with a single hand, inserting it onto the neck of the bottle 9 for actuating the hook 5 and pressing with the hand palm against the push-button 12 when the hook 5, pushed by the helical spring 7, snaps in order to block the collar 10.

Under this situation, it is not possible to tamper with the mechanism 1 in order to extract it from the bottle, since, due to the presence of the first half-circular element 11 and, possibly, of the second half-circular element 18, which are placed in front of the hook 5, the attempts of exerting a pressure onto the tip of the hook 5 to make it move backwards are inefficient.

The unlocking of the mechanism 1 can be performed with the external magnetic or electromagnetic means which, by acting on the ferromagnetic element 8, make the hook 5 go backwards, with the consequent unlocking of the collar 10 and the lifting of the toothed element 16. The lifting of the toothed element 16 generates the unlocking of the push-button 12 which, under the thrust of the helical springs 15, moves backwards, detaching the half-circular elements 11 and 18 from the neck of the bottle 9.

From the previous description, it is clear how the mechanism according to the present invention can be applied to any type and shape of bottles in such a way as to prevent possible thefts, and above all to already visually dissuade possible thieves, such mechanism being able to be easily and quickly removed, as occurs for existing anti-theft mechanisms, through its suitable detaching device. The mechanism according to the present invention is further adapted to prevent an accidental or unauthorized consumption of the contents of a bottle, as occurs, for example, when such contents are an obnoxious substance, a drug or an alcoholic beverage: such mechanism is therefore also extremely useful, for example, in a house in which, unfortunately to frequently, liquid detergents and various obnoxious substances (hydrocarbons, disinfectants, insecticides, alcoholic beverages) are placed in anonymous bottles, to avoid an accidental or unauthorized consumption or use of such substances.
