In order to sell items in the containers is displayed, they are usually made of a transparent plastic material.

If goods are paid properly, it is removed by the sales staff using only this available special tool to the container and can then trigger by the customer without an alarm be taken out of the shop. The vessel remains in the store and can be filled with a new subject will be returned back to the display. STATE OF THE ART

Security container of the type mentioned above are known for example from EP O 616 103 B1 or EP 1496179 A1. In the known containers also a cup-shaped bottom part is articulated to a shell-shaped cover part by means of hinges. The adjustable bar is in a narrow compartment between the

Front wall of the lid portion and a partition wall is housed in this part. With a closed container the bolt engages in its locking position in EP 0616103 projecting lugs with protruding contours at the bottom part. In EP 1496179 it engages in this position, into overlapping eyelets at the top and at the bottom part a.

For securing the latch in its locking position against displacement in its unlocked position with the known securing containers, a fixedly arranged in said compartment metal strip with three resilient tongues is present which engage in the locking position of the latch into recesses of the bar. For releasing the engagement of the spring tongues as a special tool shown in EP 0616103 B1 specific mechanical key is required with three angled hook.

From EP 0508201 B1 an anti-theft device comprising a container and a slidable in the container, the article to be secured enclosing with a strap bolt of a magnetic material is known, which in a in its locking position having disposed on a resilient leg locking lug engages locking slot of the container. This locking can be released as a special tool having a round on the resilient legs from the outside through the wall of the container acting magnets.

In addition to the above a number of other Diebstahlssicherungs- are devices with mechanical and / or magnetic locks known and in practical use.

It has been found that the prior art designs no longer meet the increased demands on the security completely in some cases. On the one hand are now sufficiently strong, yet very small permanent magnets relatively easily available which can unlock the magnetic locks. On the other mechanical key can get into the wrong hands and be made where necessary.

WAYS OF IMPLEMENTING THE INVENTION

The container 10 illustrated in the figures is used for securing an object, which may be in principle of any type and is not shown in the figures. The object to be protected, if necessary, including its packaging must be able to be received by the container 10th Preferably, the container of its size and shape with respect to adapted to the object to be secured, in order to apply as little as possible with respect to this. A typical dimension for the container is, for example a length of 20-30 cm, a width of 10-20 cm and a thickness of 2-5 cm. So that the matter within the container is visible, it is made of a transparent plastic material.

is designated 70 in Fig. 2 is arranged in the container tag of an electronic security system (EAS = Electronic Article Surveillance) that is detectable in a theft attempt at the output of a vehicle equipped with such a system retail store. In the event of such an attempt, an alarm is triggered. The container 10 has a cup-shaped bottom part 20 and a likewise cup-shaped lid portion 30 which are pivotably articulated by hinges 40 in the region of their rear walls 21 and 31 together.

In the cover part 30 is some distance away from its front wall 32, a partition 33 is provided, through which a narrow compartment is delimited 34th In the compartment 34 is available as a functional part of the container closure, a locking 50th The latch 50 is stamped from a metal sheet material and / or embossing produced industrially, and has two projecting noses 51. In the compartment 34 of the lid portion of the latch 50 is held by one hand, two formed on the partition wall 33 into two cams 35

engage recesses 52 of the bolt 50 and the other part is integrally formed on the front wall 32 of the cover portion 30, hold against the partition wall 33 projecting towards ribs 36 the bolt 50 in abutment against the partition 33 and thus into engagement with the cam 35th As a further functional parts of the container closure 22 hooks 23 are formed on the bottom portion 20 behind the front wall.

The bolt 50 is adjustable in the compartment 34 between an unlocking and a locking position. The two recesses 52 of the bolt are to run as longitudinal slots. Figures 2, 3, 5 b) and 8 show the latch 50 in its locking position. Only Fig. 5a) shows the bolt 50 in its unlocked position.

With a closed container 10 and the latch 50 engage around in its locking position and engage behind the two hooks 23 on the bottom part 20, the lugs 51 on the bolt 50 as b) is apparent in Fig. 5, so that opening of the container 10 is not possible , Only when the latch is brought into its Entriegelungstellung 50, the hooks 23 are no longer in engagement with the lugs 51 and the container 10 can be opened.

For adjustment of the bolt 50 serves a in the compartment 34, however, the lid part 30 fixed rotatably mounted threaded spindle 60, which is die with a permanent magnet 61 and on which a spindle nut is threaded 62nd The polar axis of the electromagnet 61, ie its north-south direction is aligned perpendicular to the spindle axis. The spindle nut 62 is fixed to the bolt. Therefore, the latch 50 can only move when the spindle nut rotates.

The displacement between the locking position and the unlocking position is, for example 7 mm. The threaded spindle 60 can be a commercially available bolt with a normal thread type M3 with a pitch of 0.5 mm in this case. then 14 revolutions are required for the said adjustment. This number is only an example. The number of rotations necessary for security reasons should not be less than 3 and vorzusweise greater than 10 degrees. It can also be greater than 50 is selected by using a screw with a fine thread entirely.

When the container is closed, the spindle nut 60 is not accessible. To rotate it from outside the container, a special tool is required. Such a tool 80 is shown in Figures 6 - illustrated. 8 With the tool 80 the spindle 60 is rotated by magnetic interaction with the magnets attached to their 61st The tool 80 forms functionally the stator of a stepping motor whose rotor is formed by the spindle.

The tool 80 is designed as a hand-held device and has a thereto correspondingly shaped housing 81. The housing 81 is provided with a retracted area, which is formed by two mutually perpendicular walls 82 and 83 thereof. Inside the housing 83 are two electromagnets in these walls 82, 84 and 85 arranged in a corner and with their poles perpendicular to these walls. Connected are the Elektromagnente 84, 85 with an electronic controller 86 which is powered by a battery or a rechargeable battery 87 with electric power. It would be possible also to connect the tool 80 via a cable to an external power source.

Due to the described geometry of the tool 80, as shown in Figures 6 can - be seen 8, are applied so with its retracted corner on one of the edges of the container 10, for example, the front outer edge 37 of the cover member 30 such that the wall 82 in contact with the lid plate 38 and the wall 83 comes to lie in contact with the perpendicular to the cover plate 38 front wall 32 of the lid part 30th In this case, the two electromagnets 84 and 85 come separated only by the walls 82 and 83 into abutment against these walls of the container to lie 10th

In the compartment 34 of the lid part 30, the threaded spindle is arranged parallel to these walls 32 and 38 and also about the same distance from this with its spindle axis 60th The threaded spindle 60 is thereby positioned at the applied tool 80 with its spindle axis perpendicular to the polar axis of the two electromagnets 84, 85 as well as about an equal distance to these.

For the function of the tool 80, it is advantageous if this is so applied to the container, that the polar axes of the two electromagnets 84, 85 come to rest approximately at the level of the spindle magnet 61st Such positioning of the tool can also be enforced by engaging, for example, a same on the tool 80 protruding pin in abutment of the tool on the container 10 in an opening. A corresponding opening in the cover part 30 of the container 10 can be seen in Figures 2 and 3 and is designated by the 39th

With the tool 80, the threaded spindle is set in rotation by the controller 86 by the two electromagnets 84, 85 are energized with current so that sectional area of ​​their pole axes and thus a rotating magnetic field produced in the region of the spindle magnet 61st Fig. 9 shows the time course of two suitable excitation currents 11 and 12, is being used as the scale along the time axis of the rotation angle of the spindle magnet 61. The value "0" corresponds to a rotational position of the spindle magnet 61, wherein its polar axis at an angle of 45 ° to the polar axes of two electromagnets 84, is aligned 85th The two streams 11 and 12 change their polarity and corresponding to the arrangement of the Elektromagente a corner of about 90 ° shifted in phase. By changing the polarity or change of the phase shift, the rotating direction of the rotary field and thus of the threaded spindle can be changed 60th

As can be seen in Figure 7, the rear end of the cores of the electromagnets 84, 85 each formed tapered. It is thereby achieved that the field lines of the magnets pass through the respective other magnet as good as not to give a lower mutual interference of the two magnets and an improved rotary field is achieved.

In the aforementioned dimensioning of the threaded spindle 60 and of the adjustment of the bolt 50 of the polarity change of currents at a frequency in the range between about 5 - 20 Heart low, and it is also desirable to increase the frequency during an adjusting. For the displacement of the latch 50 about 1 sec is required.

The tool 80 is further preferably provided with at least an operating knob 88, are activated by actuation of which the controller 86 and via this, the electromagnets 84, 85, and a displacement of the latch is triggered 50th

Of course, the controller must know 86, respectively, which direction of rotation of its respective position is dependent on a displacement of the latch 50 is required. That it might be communicated by the user by, for example two, assigned to the different directions of rotation operation buttons are provided 88th Preferably, however, means are provided by which the control of the respectively required direction of rotation can identify itself 86th

As such a means, the slider 50 could position with a small magnet 53 and the tool with a sensor for this magnet, for example in the form of a Hall probe (not shown) may be provided. The position of the bolt is then given by the relative position of the position magnet 53 to the sensor, but this presupposes that the tool 80 is always applied in approximately the same position on the container 10th but can, as described above, this can be easily ensured.

As another means for determining the respectively required direction of rotation in the container 10, a RFID tag and in the tool 80, a write and read head could (not shown) may be provided for such RFID tag. This would offer particular design the aforementioned day 70 as a RFID tag. In the RFID tag, the information about the current position of the bolt 50 could be electronically stored and read out with the read and write head before each adjustment. After each successful adjustment, the RFID tag would have to be written with the writing and reading head.

The use of an RFID tag 70 in the container 10 and at least one reading head for one such day in the tool 80 would have the further advantage that in the RFID tag, a code could be stored electronically. This code could read with the read head from the RFID tag in particular before each unlocking and compared by the controller with a stored in their code. Only if they match both codes unlocking could then be executed. In this way, a particular tool may for example be prevented be assigned 80 functionally a group of, for example, in a particular store existing containers 10 and that these containers can be opened with one another, for example coming from another store, or even recreated tool.

The tool 80 also includes means could be provided to detect the rotation of the threaded spindle and to signal for example in the clamping spindle a fault. As a motion sensor for example, the spindle could be a interconnected with the control inductor (not shown) may be provided in the region between the two electromagnets, in which by the spindle magnet during its rotation caused voltage pulses are induced. As a means for signaling a fault could be attached to the tool 80, a signal lamp 89 which could be used for signaling, however, also other disorders and / or vice versa for signaling a successful function.

Difficulties in the current replica of the tool the housing 81 could be also filled with a potting compound.

The handling of the inventive tool 80 for unlocking the inventive container, especially if use is made of the above-described preferred embodiments, very simple and requires no special skill of the operator. Hence, the inventive system from tank 10 and tool 80 is particularly suitable to be operated by the customer of a retail store, if necessary, even after they have paid for the goods contained in the container at a cash register properly.

In the embodiment described above, the latch is moved in both directions between its locked position and its unlocked position by means of the spindle. It would also mögich however, carry only the release of these and to provide another mechanism for locking.

It would be possible also to rotate in a kinematic reversal of the above described principle, a screw closure in a fixed in the container thread and thereby to screw the Behäter quasi.
