Description

The invention relates to a search container for receiving non-fluid, toxic, explosive or otherwise dangerous substances with a housing body which surrounds an interior and a closable interior access opening, the interior access opening having a sieve-like insert and a removable one Closure cap according to the preamble of claim 1.

For the education and training of sniffer dogs, the use of real substances of the corresponding substances is necessary in order to ensure that the substances are actually found in the event of a search.

The usually solid substances are placed in search containers for training purposes, which are then hidden at the search location.

The transport from the storage location of the substances to the search location usually takes place in a vehicle. The transport of search substances, which are mostly hazardous substances, is subject to the relevant dangerous goods regulations.

The search containers are usually closed with a lid after the search material has been introduced. This forms the closed inner packaging prescribed and permitted for the transport of dangerous goods.

Before the search begins, the cover is removed to allow the scent molecules of the search substances to flow out. The container is then positioned at the search location.

In almost all cases, the search substances show more or less strong toxic properties. In this respect, narcotics represent toxins. Search dogs, which are particularly suitable for this search, have a strong prey and play instinct. In practice, this leads to the dogs knocking over the opened container and even picking up search substances with their snouts. Such an occurrence can lead, on the one hand, to an undesired distribution of the search substance at the search location and, on the other hand, to oral or inhalative intake by the dog with ultimately fatal consequences. Furthermore, there is an unnecessary burden on the environment at the search location.

In usual practice, attempts have been made to avoid the risk of leakage of the search substances by only partially opening the cover, that is to say not removing it completely. It is also possible to use a special search cover with openings instead of the original transport cover.

A partial opening leads to only a small outflow of fragrance molecules and to non-reproducible conditions. An inserted lid with holes is usually contaminated when the search container tips over or the container cannot be positioned vertically for the search.

Before being transported with the top lid, it must also be packed as hazardous goods or cleaned, which entails considerable additional effort.

Furthermore, if the cover is tipped over and changed frequently, there is a risk that the search material will get stuck in the screw thread. During search tasks with explosive detection dogs, this can lead to an explosion when removing or attaching the lid, because undesired friction can already initiate the explosive material.

From the DE 10 2015 004 712 B4 a real material test body for training explosives detection dogs is previously known. The real material test body comprises an explosive accommodated by a carrier material in a housing and in this respect simulates the prior art DE 10 2009 029 787 A1 further.

The known real material test body should allow long and repeated use union.

The test body comprises an explosive contained in a solid or liquid carrier material in the aforementioned housing, which has an interior space. There is also a closure for reversible, gas-tight closure of the interior.

The carrier material with the explosive is located in the interior.

The real material test body has a gas-permeable means for preventing the carrier material from escaping from the interior space if it is not closed in a gas-tight manner by means of the closure.

Due to the gas-tight closure by means of the closure, fragrances released by the explosive cannot get from the interior to the outside of the real substance test body and cannot be perceived there by the explosives detection dog.

The closure can be implemented as a lid, cap or stopper, for example.

If the solid carrier material is in powder form, the means for preventing the carrier material from escaping from the interior can be an odor-free or at least low-odor filter material, such as glass wool and / or glass filter paper, which is placed in an opening in the interior to prevent the powdery solid from trickling out To prevent carrier material.

The housing and / or the closure of the real material test body consist essentially of glass or a metal.

The closure can be designed as a screw closure.

The interior space for receiving the search substance can be closed with a grid, which represents a means for protecting the gas-permeable component of the real substance test body for protection against mechanical damage.

The previously known real substance test body described above, however, has several significant disadvantages.

In principle, all carrier materials used for search substances potentially involve the risk of the tracking dog being unintentionally conditioned on the carrier material in the training of sniffer dogs.

There is a risk that a dog will not find the explosives installed in a booby trap, for example, because the carrier material is missing.

Furthermore, the smallest impurities with a characteristic odor in the carrier material can lead to incorrect training of the dog and its failure to detect it.

Search dogs that are only trained with very small numbers can be very irritated when searching for real, larger numbers.

It became known that dogs reported a find a hundred meters in front of a loaded explosives truck, because a sufficient number of scent molecules were perceived that were carried by the wind.

Another problem is the use of test specimens made of a glass or a metallic material. In the event of an unintentional explosion of the search container, due to the material used, high-energy fragments of their own can penetrate deep into the human or animal body and ultimately cause lethal injuries.

In addition, a dangerous, problematic chemical reaction is possible between metallic substances that are attacked by the search substance or that form third substances that distract the search dog.

In addition, it is not excluded with the previously known real substance test body that the search substance collects between the closure and the grid in the existing or remaining space when the search container is exposed to vibrations or movements, for example during transport. If the closure is removed in such a case, a large amount of search substance will escape and contaminate the environment.

From the above, it is therefore the object of the invention to provide a further developed search container which avoids the described disadvantages of the prior art and, moreover, can be manufactured inexpensively.

The object of the invention is achieved with a search container according to the combination of features according to claim 1, the subclaims representing at least useful configurations and developments.

A search container for receiving non-fluid, for example powdery, toxic, explosive or otherwise dangerous substances is assumed.

The search container consists of a housing body which surrounds an interior.

The corresponding search material is then recorded in the interior.

The housing body has a closable interior access opening, the interior access opening having a sieve-like insert. Furthermore, there is a removable, in particular screwable, closure cap.

A sieve-like insert is understood to mean a means which has openings with a cross-section or diameter which, on the one hand, securely hold back the search substance, but on the other hand, allow the escape of corresponding scent molecules.

According to the invention, the sieve-like insert, when the closure cap is in place, is closed without gaps and tightly over the entire sieve surface by a surface formed on the inside of the cap.

This measure according to the invention ensures that the search substance remains in the interior of the housing body even under difficult transport conditions and does not penetrate the basically necessary openings in the sieve-like insert, even if the grain size of the search substance changes due to transport or storage conditions.

In a further development of the invention, the sieve-like insert is designed as a sandwich construction.

The sieve-like insert has a coarse sieve section oriented towards the interior space and a fine sieve section oriented towards the access opening.

This exemplary two-stage or multi-stage design of the sieve sections achieves a high degree of security in terms of avoiding the escape of the respective search substance. At the same time, clogging of the sieve-like insert or inserts is avoided, so that, in principle, sufficient scent molecules can leave the search container in order not to endanger the training success.

Even if the coarse sieve section is possibly partially closed by search substance particles, there are smaller-volume particles in the space between the coarse sieve and fine sieve section, so that ultimately enough fragrance molecules can still leave the search container. Pushing or shaking the search container has a cleaning effect on any closed openings in the respective sieve-like insert.

It is within the meaning of the invention that the sieve-like insert is fixed in an exchangeable or detachable manner in the housing body, in particular in a force-fitting and / or form-fitting manner.

As already mentioned, the area between the coarse screen section and the fine screen section forms a safety retention space for the search material.

In a further development of the invention, the sieve-like insert has a convex or concave shaped surface which is complementary to a concave or convex counter-shaped surface in the closure cap.

In particular, this combination of the shaped surfaces enables the sieve-like insert to be sealed tightly when the search container is closed by means of the closure cap designed in this regard.

In the case of touching mold surfaces in connection with the rotary movement, with a preferred embodiment of the closure cap by means of screwing, particles may push back into the openings of the insert. In this way, an undesired escape of fine or very fine particles through the openings necessary for gas molecules to escape is prevented under all circumstances.

As explained, the closure cap can be brought into contact with the housing body via a threaded connection. There is also the option of providing a safety catch to prevent the search container from being opened unintentionally.

In one embodiment of the invention, the formation of a screw, latch or clamping means is provided on the housing body base and / or on the housing body wall. In this regard, the closure cap can be captively attached to the housing when the search container is in use.

After completion of the respective use and search process, the closure cap is then removed from the bottom of the housing body and, as described, the opening of the housing body, that is to say the interior access opening, is screwed.

The mating surface in the closure cap can have elastic or plastic properties, so that an optimal closure of the openings in the sieve-like insert is possible.

According to the invention, all search container components consist of a non-metallic material, in particular a plastic material.

In the event of an explosion of the search container when an explosive is used as a search substance, this avoids high-energy fragments of its own.

As a result of the gap-free and tight closure design, it is impossible for search material to become stuck in the area above the sieve-like insert, for example in the screw thread of the closure cap. This effectively eliminates the risk of an explosion in the thread caused by stray material particles.

The interior of the search container is designed in terms of its volume in such a way that sample and search substances, that is, real substances, free of carrier media, can be accommodated in an amount equal to or greater than 5 g.

In order to be able to check the content of the samples or search substances taken in with regard to quantity and presence, the housing body is made at least partially transparent.

In an embodiment of the invention, it is possible to provide a scale for identifying the filling quantity on the housing body. Furthermore, there is the possibility of forming a surface on the housing body which enables relevant information about the search substance, the filling date, the use or the like, possibly also in coded form, to be recorded.

According to the invention, the use of the search container in the described embodiment for training and further training of sniffer dogs by means of real substances is furthermore.

The invention is to be explained in more detail below using an exemplary embodiment and a figure.

The figure shows a basic sectional illustration through an exemplary search container, which is designed as a cylindrical vessel with a closure cap.

It is therefore from a housing body 1 assumed in an exemplary cylindrical shape.

The housing body surrounds an interior space 2 .

At an upper end of the case body 1 there is an interior access opening.

The interior access opening has a sieve-like insert 3rd on.

There is also a removable cap 4th available.

Through a thread formation in the upper area of the housing body 1 as well as inside the cap 4th with a right-hand thread configuration, as indicated by the curved arrow, the closure cap 4th on the case body 1 be fastened by screwing.

When an end position is reached, there is a safety catch 5 to the effect of an undesired loosening of the sealing cap 4th to prevent.

By screwing on the cap 4th on the housing body 1 the cap moves 4th in the direction of the arrow (shown on the right in the figure).

The inside of the cap is a surface 6th formed, which with the reaching of the end position of the cap 4th based on their position in relation to the housing body 1 the entire surface of the sieve-like insert 3rd , i.e. the screen surface, closes tightly and without gaps.

The sieve-like use 3rd owns one to the interior 2 oriented coarse screen section 7th and a fine screen section directed towards the access opening 8th .

Between the coarse screen section 7th and the fine sieve section 8th a safety restraint remains 9 , in which possibly through the coarse sieve section 7th Penetrated particles of the search substance are caught and retained.

The openings in the fine sieve section 8th have a significantly smaller diameter than the openings in the coarse sieve section 7th .

The entire sieve-like operation 3rd is in the housing body that is open at the top 1 Pressed in in a force-fitting or form-fitting manner, specifically up to a circumferential stop formed on the inner circumference 10 .

In the example shown, the sieve-like insert 3rd a concave free-form surface 11 on, which leads to a convex counter-shape surface 12th in the cap 4th is complementary.

It is in the sense of the invention that an inversely complementary design of the counter-form surface and free-form surface can also be implemented, whereby the desired tight and gap-free closure of the screen surface, i.e. in the example shown, the one with the fine screen section remains decisive.

There is a section on the housing body base and / or on the at least lower housing body wall 13th for the formation of screwing, latching or clamping means, in order to ensure that the closure cap cannot be lost 4th (shown in dashed lines in the figure) when using the search container.

The case back can 14th have a shape that of the corresponding counter-shape surface 12th in the cap 4th is complementary.

The counter-form surface 12th in the cap 4th has elastic or plastic properties in order to optimally close and seal the openings in the sieve-like insert 3rd to guarantee.

All components of the search container are made of a non-metallic material, in particular a plastic material.

The interior 2 of the search container forms a volume for receiving carrier material-free, i.e. pure sample and search substances in an amount greater than or equal to 5 g.

At least parts of the housing body 1 are transparent and / or have a scale to indicate the filling quantity.

The closure cap can be on the outer circumference 4th another knurling 15th for easier screwing, especially when working with gloves for safety reasons.

In order to avoid confusion when assigning sealing caps to the search container, there is the option of color coding, for example by coloring the plastic materials used. This also prevents contamination of the search substances through, for example, incorrectly used sealing caps or unsuitable sieve-like inserts. These can also be included in the color coding.

Depending on the temperature, the search substances are known to give off fragrance molecules to a small or significant extent. When searching with the objective search body, the dog trainer can control the amount of molecules flowing out by simply opening the lid slightly or removing it completely, in order to provide the dog with an approximately identical scent, even at very different temperatures.

The cover can be completely removed in winter and only slightly screwed on in summer to partially break the seal. A different material configuration, which could irritate the dog, does not exist in the present search container.
