Description

Safety device for beverage cans.

Object of the invention.

The present invention relates to a safety device for beverage cans, especially applicable to those beverage cans provided with a perimeter flange in their upper zone; said safety device being the type of those comprising a passive emitter for the activation of an anti-theft alarm when passing through the area of influence of an antenna or detection device.

Field of application of the invention.

This device is applicable in the sector dedicated to the manufacture of anti-theft security device for products in commercial establishments.

Background of the invention.

It is currently a common practice to incorporate various articles of security devices intended to be fixed on diverse products, in order to prevent their theft in commercial establishments.

These safety devices comprise a passive emitter that causes the activation of an alarm when passing through a control zone provided with an antenna or detection device.

Depending on the technology applied, the passive emitter can be activated by an AM (acoustic-magnetic), RF (radiofrequency) or RFID (radiofrequency with identification) emission antenna.

Depending on the item to be protected, safety devices with different configurations are used.

In some cases, this safety device adopts an adhesive label configuration that is fixed directly on the item to be protected so that it is as concealed as possible.

In other cases, for example in garments, it is usual to use safety devices consisting of two half-shells, one of them having a punch to pass through the garment to be protected and the other a hole for receiving the end of the aforementioned awl; being said punch associated with blocking means magnetically operated bias.

The incorporation of these safety devices in certain products such as beverage cans is not adequate since in the case of using an RFID adhesive label, said label is in a visible position, so it can be easily removed, leaving the can unprotected against Theft.

The safety devices provided with two pieces and a joint punch to pass through the article in question and establish the union of said pieces on two opposite sides of the article are not applicable, for obvious reasons, in beverage cans.

An example of this type of safety element is described in document ES 1074794 specifically referring to a multifunctional alarm label.

The technical problem that arises is the development of a safety device for beverage cans that allows its application on the can, without deteriorating it and that cannot be easily released, for example by peeling, as is the case with adhesive RFID tags.

Description of the invention

The safety device for beverage cans object of this invention is especially applicable to those beverage cans provided with a perimeter flange in its upper zone, said safety device comprising a passive emitter for the activation of an alarm when passing through the zone of influence of an antenna or detection device.

To achieve the proposed objectives, and according to the invention this safety device comprises a rigid housing that has:

-

an inner cavity, closed, in which the passive emitter is housed;

-

a lower, open cavity, for receiving the upper end of a beverage can, said lower cavity having fixed teeth and a retractable tooth associated on its lateral surface with locking means in an outstanding operative position in which said retractable tooth it forms, together with the fixed teeth, means for blocking the perimeter flange of the beverage can inside said lower cavity and;

-

an upper, open cavity, forming a seat for the stable support of the lower end of a beverage can stacked superiorly.

With the indicated characteristics, to place the safety device on the beverage can to be protected, it is enough to position it on the upper end of the can, so that the fixed teeth and the retractable tooth located inside the lower cavity of the can lower the perimeter flange, defined in the upper part of the can by the union of its side wall with the upper cover, preventing said teeth from being removed from said safety device until the means of blocking the retractable tooth are released and this can be released go back to an inoperative position.

The means for locking the retractable tooth in the outstanding operating position may be constituted by a magnetic key, analogous to those used in other safety devices, widely known and used for the protection of clothing, or by any other means of blocking that they are considered adequate and cannot be fraudulently manipulated by the general public; since the nature of these blocking means does not constitute an essential feature of the invention.

The definition in the housing of the device of said upper cavity, forming a seat for the stable support of the lower end of a beverage can stacked superiorly, is an important feature since it allows the beverage cans provided with the safety device of The invention can be arranged stacked, as usual in commercial establishments.

In an embodiment of the invention, the upper cavity of the housing is delimited inferiorly by a closing lid of the inner cavity, said closing lid being permanently fixed, for example glued or heat-welded to the housing of the device.

Description of the figures.

To complement the description that is being made and in order to facilitate the understanding of the features of the invention, a set of drawings is attached to the present specification in which, for illustrative and non-limiting purposes, the following is represented:

-

Figure 1 shows a perspective view of an embodiment of the safety device for beverage cans according to the invention.

-

Figure 2 shows a bottom plan view of the safety device for beverage cans according to the invention.

-

Figure 3 shows a perspective view of the security device of the previous figure in which the closing cover that inferiorly delimits the upper cavity has been removed and in which the passive emitter, constituted in this case by an RFID tag has been represented extracted from the inner cavity.

-

Figure 4 shows an elevation view of the safety device of the previous figures sectioned by a vertical plane, positioned on the upper end of a beverage can, the upper end of a second beverage can stacked vertically stacked in this figure. and supported with its base on the seat or upper cavity of the security device of the invention.

Preferred embodiment of the invention.

As can be seen in the attached figures, the protection device for beverage cans object of this invention comprises a housing (1) in this case of cylindrical configuration having a closed inner cavity (11); a lower cavity (12) open for receiving the upper end of a beverage can (L); and an open upper cavity (13).

A passive emitter (2) represented in this case by an RFID tag is housed in the inner cavity (11), this inner cavity being closed

(eleven)

superiorly by means of a cover (14) constituting the bottom of the upper open cavity (13). As can be seen in figures 1 and 4, this cover (14) has an inverted truncated conical configuration so that the upper cavity

(13)

It forms a seat for the stable support of a second can of beverage stacked vertically as shown in Figure 4.

The lower cavity (12) intended to receive the lower end of the beverage can to be protected has laterally fixed teeth (15) that can be seen in Figure 2, and a retractable tooth (16) associated with blocking means ( 3) constituted in this specific case by a magnetic key.

As can be seen in Figure 4, in the position of use the fixed teeth (15) and the retractable tooth (16) of the device act on the lower area of the flange (R) usually defined in the upper area of the cans (L ) of drink in correspondence with the area of union of the side wall and the upper lid of the can, preventing said teeth (15, 16) from releasing the safety device positioned on the can (L) of beverage.

By releasing the blocking means (3), for example, by exposing it to a magnetic field, it is possible for the retractable tooth (16) to move towards the outside of the device, releasing the perimeter flange (R) and consequently allowing the release of The can of drink.

Once the nature of the invention has been sufficiently described, as well as a preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not imply an alteration. of the essential features of the invention that are claimed below.
