The invention relates to a one-piece security seal and an _o-CEM Versiegelungssys

There are "already known various systems in which two elements to be sealed or sealed with one another are suitable for receiving a security seal, the Separation only in the event of an intentional or criminal breach of the seal enabled two basic types of Seals have hitherto been used, one of which is a one-piece, is a deformable seal with the help of a tool (e.g. "the particularly well-known lead seal or" the lead seal, which is deformed over the two ends of a cord closing a mailbag or the like) and a two-part seal, where one part is manually inserted into the other (e.g. those described in British Patents 1,312,300 and 1,400,760 Seal).

The object of the present invention is to create a one-piece security seal that is attached to the two

other elements to be sealed without need for use a tool for deforming the seal can be placed over these elements and that for separating the two Elements can be broken easily, the one-piece seal being the only element that is destroyed · Object of the invention it is also a particularly suitable one for such a security seal Sealing_system_ to be specified.

In this connection it should be noted that if a mailbag or the like sealed with a seal is opened, the string must be cut, which is then thrown away later. The same applies to the seal described in British Patent 1,312,300 . In the German patent application P 24 49 909 _e 0 a label holder is described which can be used together with a security seal similar to the seal disclosed in British patent specification 1 312 300 and has the advantage that the mailbag can be closed so that when Break open this., Seal that has a capsule and an insert onaas seal ^& * ^r

points / is the only element that is lost, while the string and label holder are both reusable «If the one-piece seal according to the present invention together with a correspondingly modified embodiment of the above is used, the one-piece seal is the only element that has to be thrown away of this, the seal according to the invention is also particularly easy to handle, since it is applied with light hand pressure can be.

According to the invention, a security seal has a single element which consists of an insert part, which is plastically deformable and attached to a second part via a weakened zone, which is broken off the weakened zone is removable. Preferably, the male part has a rectangular / base, a saddle part that extends extends perpendicularly from the center of the base and on the two opposite sides of the free end of the central part two elastically deformable arms that extend outwards and backwards towards the

609842/0342

26U126

The base is inclined, the second part having a blade, the width of which corresponds approximately to that of the base and is connected to this via the weakened zone _e

Furthermore, according to the invention, a sealing system two elements to be sealed or sealed with one another, the first of which has a first part with a first through opening and the second element has a second part with a second opening, the two Openings in the sealing or closed position of the two elements are aligned. Enclose in this position the two elements form a closed cavity behind the second opening on that side of the second part which is from the first part is removed. This cavity has, at least in the area of the second opening, a larger cross-section than the second opening and in the sealed position is only accessible from the outside through the two aligned openings, while it is freely accessible when the two elements are separated. This sealing system also includes a Security seal of the above-mentioned type, the plug-in part of which fits through the two openings j while being moved through undergoes elastic deformation through the second opening and then behind the second opening and within the Cavity is held, and wherein the weakened zone of the seal in the sealing position behind the first opening lies, i.e. on its side associated with the cavity.

As mentioned earlier, the security seal and sealing system is particularly useful for use with the in the German patent application P 24 49 909oO described Label holder, so that the invention is described here in connection with such a label holder. The content of the German Patent application P 24 49 909.0 is expressly made part of the disclosure of the present patent application. Further developments of the invention emerge from the subclaims.

The invention is illustrated below with the aid of partially schematic representations explained in more detail using two exemplary embodiments. Terms such as "horizontal" and "above" are used to mean that a label holder lying flat is considered. Show it:

Pigo 5 is a front view of the capsule and cap portion according to Pig. 4th

In Pig. 1 shows a molded plastic label holder with the novel one-piece security seal 1 is to be closed, which is shown in detail in Pig «3. The seal 1 has an insert part 2 and a detachable or detachable partition part 3. The plug-in part 2 has a rectangular base 4, a central part 5, which extends perpendicular to it from the center of the base, and two arms 6 and 7 'which are on opposite sides of the free end 8 of the middle part 5 and begin to move outwards

and extend backwards towards the base. The seal 1 is total designed flat.

The separating part 3 of the seal according to the invention has a blade 9 which has a thicker rectangular base end 10 of has the same thickness as the plug-in part 2. The base end 10 is attached to the base 4 of the male part via a weakened connection, the weakening of which in the case of the one shown here Seal in the form of two small webs 11 is shown.

The seal 1 is molded from a plastic so that the arms 6 and 7 have a certain flexibility that theirs allows elastic deformation when the seal is attached to a sealing system. As shown in Figures 1 and 3 shown, the flexibility of the arms 6 and 7 is thereby increased

609842/0342

26U126

facilitates that at the free end 8 of the central part 5 of the male part a small elongated recess 12 is provided, which is perpendicular to the plane of the male part.

The plastic material from which the seal is made is preferably polypropylene.

Figo 1 is a perspective view of a plastic molded label holder 13, which largely corresponds to that shown in German patent application P 24 49 909 · 0, so that only a brief description of the basic structure is provided here is given. As can be seen from the drawing, the label holder 13 has two parts 14 and 14 molded in one piece 15, which can be folded over one another and in the closed position are suitable for receiving a paper label, part 14 is with a fixed coil 16 molded in one piece, while part 15 with a cap 17 is formed in one piece, which when closed The label holder fits over the spool 16. One end of a string can be fastened in a hole 18 in part 14 while the cord is then looped around a mailbag or the like at the top and then wound around the spool before the parts 14 and 15 are closed will. The present invention relates primarily Line on the new system for sealing the cap 1? on the spool 16, which is substantially different from that in the above German patent application P 24 49 909.0 differentiates "

The sealing system essentially has a wall 19 which is formed on the top 16 'of the coil 16 and perpendicular to the Upper side 16 'fortragt, as well as a "capsule" 20, which is formed in the upper or peckel part 21 of the cap 17 and opposite the otherwise flat top of the cap 17 protrudes. The wall 19 has a rectangular through opening 22 of a slightly greater height than it corresponds to the thickness of the plug-in part 2 and of a width which is slightly smaller than the distance between the free ends 24 'of the arms 6 and 7 on the plug-in part and slightly larger than the width of the base 4. Consequently, by elastically deforming (compressing) the arms 6 and 7 through the opening 22, the male part 2 can be opened slide through. Behind the opening 22 are two shoulders 23 below inclined at an angle which essentially corresponds to the inclination of the

surfaces 6 * and 7 ^{f of} the arms 6 and 7 in. not deformed em state corresponds o These shoulders 23 can be clearly seen from FIG.

The capsule 20 is open on the inside or underside so that it is accessible from the inside of the cap 17. The upper Side of the capsule is through a lid or a flat top

circumferential

24 closed. The capsule also has a side wall 25 an opening 26 having substantially the same dimensions has like and can be aligned with the opening 22 when the label holder 13 is closed, the spool 16 is covered by the cap 17. The shape of the side wall 25 and the top 24 of the capsule is not extraordinary of great importance if an inner cavity 27 is formed when the cap is placed on the spool, the size of which is to accommodate of the plug-in part 2 is sufficient, the only possible access being through the openings 22 and 26 which are aligned with one another is required. In the embodiment shown here, the shape of the capsule generally corresponds to that of the plug-in part 2, and the side wall 25 has a small vertical inner rib 28 which in the sealing position extends into the recess 12 extends in the plug-in part 2 "

As can be seen from FIG. 2, when the label holder 13 is closed, the spool 16 is fitted into the cap 17 is, the wall 19 into the capsule, and the opening 22 comes to lie next to and behind the opening 26. It is recognizable, that the top 16 'of the coil closes the capsule 20 and serves as the bottom, and ensures that the only possible Access to the inner cavity 27 through the two openings 22 and 26 consists. Once the wall 19 has entered the capsule 20 is, the one-piece seal 1 can be attached to the system that the male part through the two openings 22 and 26 is inserted «, that is only by elastic compression the arms 6 and 7 possible, which, when they have reached the shoulders 23, open again, so that they are so behind

fi 0 9 8 A 11 0 3 4 2

_ 26U126

the shoulders grip so that the male part 2 remains within the cavity 27 in the capsule ". The base 4 of the male part remains within opening 22 and prevents any further element from entering through that opening. Likewise, the bear earth 10 of the blade 9 fills the opening 26 in the wall 25, so that the cavity 27 is even better secured against an attempted injury. The two weakened bars 11 of the seal 1 are in the gap between the two openings 22 and 26.

Pigβ 2 shows the seal already attached to the system, which is sealed in a secure and non-vulnerable manner. It should also be mentioned that the insertion of the insert part 2 in the cavity 27 is an extremely easy process, because it only needs the blade 9 held and the insert part through the openings 22 and 26 to be pressed. Only a small amount of force is required for this, since the arms 6 and 7 are correspondingly flexible so that the sealing process is only a matter of seconds. The flexibility of the arms 6 and 7 diminishes in in no way the security of the system, since a tensile force applied in the direction of pulling out the plug-in part 2 causes the arms 6 and 7 to tend to open further, whereby their engagement behind the shoulders 23 becomes even more secure.

The process of opening the label holder is also extremely simple. It is only necessary to use the blade 9 grasp and pull outwards and sideways, whereby the webs 11 are broken and the blade removed can, while the plug-in part 2 remains in the cavity 27. After removing the blade 9, it is possible to lift the cap 17 and to open the label holder. The plug-in part 2 is then on top of the spool 16 and can be easily removed will. The cord, not shown here, can then be unwound from the spool 16 and from the top of the mailbag, so that both the The label holder 13 itself and the cord are left in excellent condition for reuse. The only

The element to be thrown away is the seal 1.

To further improve the system, the upper side 16 'of the coil is designed with two ribs 29, the upper end surfaces of which align with the underside of the opening 22 in the wall, so that it is ensured that the plug-in part within of the cavity 27 is supported horizontally. The height of the ribs 29 also corresponds to the thickness of the cover part 21 of the cap 17, so that the top of the lid part 21, the bottom of the openings 22 and 26 and the top of the ribs 29 all lie in the same plane when the device is closed.

Even if in the drawings the webs 11 in the gap between the openings 22 and 26 are so that the label holder can be opened, if these are broken through, this can Weakening also lie within the opening 22 or even within the cavity 27, provided that the broken off Part is removable so that the device can be opened. However, it is not possible to weaken the ab to be provided within the opening 26 in the capsule, since it is broken of the seal, only the blade 9 could be removed while the spool and cap remained sealed together.

In Figures 4 and'5 is a label holder with a Seals of the same basic structure as shown in Figures 1 to 3, but with a few other, sometimes preferred aspects which have been found to be particularly useful in experiments. The reference symbols used in FIG also all appear in Fig. 4. In this embodiment there is opening 26 in the capsule on both sides 2o a protective wall 3o is provided, which extends at right angles to the plane of the opening 26. This is between them

60984 2/0342

_ ₉ _ 26U126

a passage through which the plug-in part 2 of the seal is pushed before it enters the capsule is formed on both protective walls. The two walls 3o preferably have a somewhat greater distance from one another than the distance between the end faces 6 'and 7 ^{1 of} the arms 6 and 7 of the seal 1 in the non-deformed state. This ensures that there is no difficulty in applying the seal because it would have to be pressed along the passage delimited by the walls 30.

It is possible to provide the walls 3o as planar structures standing upright from the cover part 21 of the cap 17; but they are preferably given an L-shaped section, as shown in FIG. 4, with one of the legs 31 of the L parallel to the cover part 21 is at a distance from this and points inward. It should also be mentioned that the legs 31 have a distance from one another, the corresponds approximately to the width of the blade 9 of the seal 1, as this makes the top of the blade clearly visible in practice is formed with an individual identification number for security reasons.

The seal itself according to FIG. 4 has two opposite lateral extensions or wing-like areas 32 in that area of the blade 9 which comes to lie between the protective walls 3o when the device is in the sealed position. The total width of the blade 9 in the area of the extensions 32 is preferably identical to the distance between the end faces 6 ¹ and T of the arms 6 and 7 of the insert part 2 or, in other words, slightly less than the distance between the protective walls 3o. In order to avoid an accumulation of tensions in the blade 9, where it is connected to the base end 1o, the seal 1 shown in FIG. 4 is also provided there with a transition bevel 33. This eliminates any possibility of the seal breaking in the wrong place when the label holder is opened.

It should be pointed out here that in the absence of protective walls 3o and extensions 32 there is a possibility could that the weakened zone 11 of the seal when

609842/0342

26U126

Transport breaks unintentionally. However, the provision of these additional features offers protection from such unintentional opening the seal.

It is obvious to a person skilled in the art that the seal according to the invention is also used in other sealing systems may be different from the one related to the label holder described differ. The seal according to the invention can be applied in any case in which two Elements to be sealed in the closed position, two aligned openings and one receiving an insertion part Have a cavity to which access is only possible through these openings. It is also essential that the cavity is easily accessible when the elements are separated so that the male part can be removed from the Blade has been severed to open the system. An example of a modified form of the system would be sealing a box comprising two open-ended boxes which telescopically fit one inside the other. The bigger box that surrounding the other in a telescopic Y-shape would have a projection on a side wall in the Hahe of the open end with an opening perpendicular to the longitudinal axis of the box. There is one near the closed end of the other box Side wall provided with an outwardly protruding part, which in a manner similar to the capsule shown in Fig. 1 is shaped. This capsule would then have a slot in the longitudinal direction of the box, into which the projection on the first box is inserted can be. The capsule would also have a side opening that would align with this protrusion. At this Arrangement, the one-piece seal according to the invention can be attached through the two aligned openings.
