Method for equipping a plastic injection-molded transport or storage structure with a remote-readable escort memory and a plastic injection-molded transport or storage structure with a remote-readable escort memory 5

The invention relates to a method for equipping a plastic injection-molded transport or storage structure with a remote-readable escort memory. Previously known methods have been those in which an encapsulated enclosure, for example by gluing or screwing, is attached to a finished injection-molded and identifiable transport or storage structure, such as a box, container, transport base or similar structure, for example by gluing or screwing. There are several disadvantages and drawbacks to the above and other prior art methods.

The principle and at the same time the weakness of the known solutions is that the retrieval memory is subsequently placed in a product manufactured earlier in the manufacturing process, such as a plastic box, which is to be identified by the escort memory. In addition, the known methods are laborious in terms of production technology and, in addition, the external dimensions of transport or storage structures, such as boxes, produced by known methods can change, and this can complicate other handling of the box, for example on a production line. In known solutions, it is possible to remove the identifier, i.e. the accompanying memory, from the desired product for identification without breaking the product. This feature is particularly disadvantageous when the access memory is used for marking valuable or otherwise important products, because, for example, in cases of theft, it is still more difficult to verify the owner of the product if the access memory has been removed from the product itself.

It is an object of the present invention to provide a new type of method which avoids the problems associated with the known solutions.

This object is achieved by the method according to the invention, which is characterized in that the escort memory is first placed in connection with the escort memory protection structure, the injection molded plastic 10 completely or partially surrounds the pre-sealed protective structure including the escort memory and forms the protective structure and the escort memory as part of the wall structure.

The method according to the invention is based on the idea that the escort memory is integrated as an integral part of the product to be identified already at the product manufacturing stage.

The method according to the invention achieves several advantages. The integration of the escort memory into the structure of the injection-molded plastic box or similar product at the manufacturing stage ensures that the escort memory does not increase the external dimensions of the product. The permanence of the external dimensions as original is important so that the connection of the accompanying memory does not cause a problem situation in which the excessive external dimensions of the product may complicate other handling of the product. The transport memory of the transport-25 or storage structure is also located in a place that can withstand high wear, i.e. on the wall of the product and not on the surface of the wall, as in previously known methods. The persistence of the external dimensions also means that the surface of the product to be identified remains smooth, so that the product 30 does not leave seams which would be problematic in terms of mechanical wear, durability, tightness, cleaning or, for example, bacterial growth, the latter being of particular importance. the transport and storage structures to be identified, such as the box used in the food industry, fell 90850 3 in slaughterhouses. The method according to the invention also provides production advantages, since the pre-closing step does not require the treatment of the entire identifiable body. The use of a protective structure to protect the accompanying memory myds improves the ability of the components of the injection molding sensitive to the pressure and temperature of the injection molding to withstand the injection molding manufacturing process. The accompanying memory can also be placed invisible inside the structure if desired.

The reduction of mSarSn 10 of product thefts and the detection of thefts is facilitated by the fact that it is not possible to remove the escort memory identifying the product, such as a transport box, from the transport box without breaking the transport box itself.

The invention also relates to a plastic injection-molded transport or storage structure with a removable escort memory, such as a box, container, transport tray or similar structure, comprising an injection-molded wall structure and a removable escort memory for identifying the transport or storage structure.

With respect to the prior art structures and their epS sites, reference is made to the prior art methods and structures fabricated therein.

In order to eliminate the drawbacks of the known solutions, the transport or storage structure according to the invention is characterized in that a substantially uniform protective structure consisting of opposite structural parts and a protective structure and that the injection-molded plastic of the wall structure is adapted to form the final closure of the silent closure of the opposite components of the protective structure.

The advantages of the transport and storage structure 4 according to the invention are similar to those described above for the method.

The invention will now be described in more detail with reference to the accompanying drawings, in which Fig. 1 shows the escort memory and its reader device in a simplified schematic diagram, Fig. 2 shows the escort memory and its protective protection structure in separate parts, Fig. 3 shows the structure according to Fig. 2 and a first embodiment from the first half of the escort memory protection structure viewed from the outside, Fig. 4b shows a first embodiment from the second half of the escort-memory protection structure viewed from the inside; viewed from the inside of the half, Fig. 5 shows a protective structure assembled from the halves of the protection structure shown in Figs. 4a and 4b, Fig. 5a shows a cross-section Fig. 6 shows the arrangement of the escort memory with the protective structure on the wall of the plastic box; Fig. 7 90850 5 Fig. 9c shows a third embodiment of a guarded escort memory arrangement, Fig. 9d shows a fourth embodiment of an escorted memory arrangement.

Figure 1 shows a companion memory and its reader device in a simplified schematic diagram. Briefly, with reference to Figure 1, the structure of the identification system will be described. The identification system comprises a transmitter memory 1 and a reader device 2. The transmitter memory 1 comprises a transmitter / receiver unit 10 and a coil 4 connected thereto. . The operation of the detection system is based on the mutual induction between coils 4 and 6. However, the essential part of the present invention does not relate to the escort memories themselves and their technology, so reference is made to the prior art and, for example, to US-4,752,776 and DE-3 412 588. The escort memory can be inductive, RF sensor or ultrasonic. Thus, the data transmission between the accompanying memory 7 and the reader device takes place by means of an electromagnetic field or ultrasound.

Figure 2 shows the escort memory and the protection structure in separate parts. In Fig. 2, the escort memory is shown as a whole with reference numeral 7, which functionally corresponds to the escort memory 1 in Fig. 1. The escort memory 7 in Fig. 2 is as a whole and is a transmitter / receiver unit and a coil as in Fig. 1. Around the escort memory 7, two opposite structural parts 8a and 8b are formed, i.e. a protective structure comprising a half 8. The halves of the protective structure, i.e. the structural parts 8a and 8b, are substantially similar and are mirror-aligned against each other in Fig. 3, , 8a, 35 8b pre-closure by pre-closing the halves of the protective structure 6 together in a sealing seam 9, which in practice means, for example, a quick-fastened, ultrasonic hit or glued interface between the components 8a and 8b, i.e. the halves of the protective structure. In pre-closing, a so-called an insert thus consisting of an escort memory 7 and a protective structure 8 protecting it, in which the seam 9 between the components or halves of the protective structure is pre-closed.

Fig. 4a shows the first half of the accompanying memory protection structure 10, i.e. the structural part 8a, viewed from the outer surface side. In Fig. 4b the second component 8b is shown in the opposite direction, i.e. from the side of the accompanying memory, i.e. from the inside, it is seen from Fig. 4b that the component 8b comprises a pushed groove 10 coil and t-15 11 itself with exposed or encapsulated microcircuits and other possible components. The groove 10 for the coil and the space 11 for the microcircuit can be formed on both halves of the protective structure, if necessary. The access memory microcircuit may be, for example, a "read 20 only" type fixed code circuit or a programmable "read / write" type microcircuit.

Fig. 6 shows the arrangement of the escort memory 7 provided with the protective structure 8a, 8b in the wall 14 of the plastic box 13. Fig. 6 also shows on the right side 25 the escort memory 7 with its protective structures 8a, 8b still detached. Fig. 7, in turn, shows a mold 15 used in the manufacture of a plastic box, comprising an upper mold half 15a and a lower mold half 15b, which are divided or diverged along a dividing plane A, although the sloping part 30 in the middle belongs to the upper mold. In addition, the mold structure comprises a lower suction channel 16 for molten plastic and in addition a feeding means 17, i.e. a so-called The area 18 between the mold halves 15a and li 90850 7 15b in Figs. 7 and 8 is the area in which the injection molded plastic forms a wall structure similar to that shown in Fig. 6, in which the insert, i.e. the pre-enclosed accompanying memory and the assembly formed by the insert, can be placed in the mold structure 15. -to 14 plastic box 13.

Referring to Figures 2, 3, 6 and 7, in a method according to the invention, a plastic injection-molded transport or storage structure such as a plastic box 13 is provided with an readable escort memory, the escort memory 7 first being placed in connection with the escape memory protection structure 8, i.e. and 8b v & -10 line. Next, the access memory 7 is pre-closed by pre-closing the access memory protection structure 8, at which point in practice the closing seam 9 between the halves of the protection structure is, for example, welded or glued or the halves 8a and 8b are fastened together by a plurality of fastening means 12a and 12b. In the next step, the final sealing of the accompanying memory 7 and the protective structure 8, 8a, 8b, i.e. together the insert, is performed by injection molding, whereby the transport or storage structure such as the wall , 8a, 8b and forming the protection structure and the escort memory into the wall structure 14.

In a preferred embodiment of the method according to the invention, a protective structure containing a pre-closed escort memory 7 is placed in connection with a mold 15 used in injection molding of a transport or storage structure in a mold-delimited area 18 which is filled with molten plastic and forms a box wall 14.

The injection molding itself is carried out in a manner known per se. Injection molding, or injection molding, is the most widely used method, especially as a method of manufacturing thermoplastic products. However, injection molding is also suitable for disposable molds. In the injection molding of thermoplastics, the raw material is kSytetaé 35 solid granular plastic, i.e. granulate, which is initially plasticized by means of a lamina and mechanical mixing. The plasticized plastic mass is injected into the mold and, after a suitable cooling time, the mold is opened and the finished product, such as a thin-walled plastic box, is removed from the mold.

Figures 9a to 9d show different cross-sections of the plastic box wall 14. The figures show different ways of placing the insert, i.e. the pre-closed accompanying memory and the assembly 8a, 8b, as part of the thin-walled plastic box wall structure 14. Each half of the protection structure 10 a smooth planar outer side, wherein the first half 8a covers the outer side 8c and the second half 8b of the protective structure covers the outer side 8d. According to Figures 6, 9a and 9b, in a preferred embodiment of the method according to the invention, the wall 14 to be formed on an injection-molded transport or storage structure such as a box 13 is injection-molded substantially flush with at least the second outer side 8c, 8d of the access memory. In Fig. 9a, the wall 14 is injection molded 20 in the same plane as both the outer side 8c of the first protective structure half 8a and the outer side 8d of the second protective structure half 8b. In this way, the method becomes simple to implement, the thickness of the Silia taild insert substantially corresponds to the thickness of the box wall, and this allows the insert to be pressed directly onto both mold halves 15a and 15b.

In a preferred embodiment of the invention, before pre-sealing the protective structure 8a, 8b, the protective structure 8 is filled with a filler such as polyurethane, epoxy or silicone. In this way, gas bubbles are removed from inside the insert, which improves the environmental tolerance, manufacturability and yield of the insert.

According to the invention, a plastic injection-molded transport or storage structure 35 with a front-loading escort memory 7, such as a box, is shown in particular in Fig. 6.

II

90850 9 it should be noted that the term transport and storage structure should be understood to cover different and different types of products such as containers, tanks, pallets, pallets or similar structures used for the transport, transfer, storage or other similar purposes of other products or objects. The term transport and storage structure also includes a part of the transport or storage structure such as a cover or other similar functionally tSr part.

Referring to Figures 2 to 6 and 9a to 9d, a thin-walled plastic box 13 comprises an injection-molded wall structure 14 and a remotely readable escort memory 7 for identifying the box 13, or more broadly, the transport or storage structure 13. According to the invention, a substantially uniform protective structure 8 is formed around the accompanying memory 7 in the sealing seam 9 to be included in the pre-closure. As an integral part of the wall 14 and then the injection molded plastic of the wall structure 14 is adapted to form the final closure of the sealing joint 9 between the opposite structural parts 8a, 8b of the protective structure 8.

In a preferred embodiment of the plastic injection-molded transport or storage structure with the front-loading escort memory 25 according to the invention, e.g. the box 13, the opposite structural parts 8a and 8b of the escort memory 7 protection structure are thin injection-molded plastic sheets as shown in Figures 2-4. The thin plastic sheets forming the protective structure are, of course, injection molded in another context and much earlier than the injection molded wall structure 14 of the box 13 itself.

Thus, in said embodiment, both the protective structure 8, 8a, 8b and the product 13 to be self-identified, i.e. the box 13, are injection molded, whereby the implementation of the protective structure 10 is preferably performed from two opposing thin injection molded plastic sheets. Fig. 5 shows a unitary protective structure assembled from the components according to Figs. 4a and 4b, i.e. the halves 8a, 8b of the protective structure 8, inside which the access memory 7 is arranged in a manner corresponding to Figs. In Fig. 4a, the first half or component 8a of the protective structure is viewed from the outside, while in Fig. 4b the second half or component 8b is viewed from the inside, i.e. from the side of the accompanying memory 10 to be placed. In view of the above, it can be seen from Fig. 4b that in the protective structure, i.e. in practice, the second half 8b of the escort housing comprises the groove 10 along the escort coil and also the space 11 for the escort circuit itself and any other necessary components. Fig. 15 is fasted to the structure according to Fig. 5 when the first half 8a of the escort memory protection structure shown in Fig. 4a is placed against the second component 8b shown in Fig. 4b, but with an escort memory first attached to it, thus consisting of an escort circuit and a coil. It can be seen from Figures 2 to 6 and 9a to 9d that in a preferred embodiment of the invention a plastic injection-molded transport or storage structure 13 with a removable escort memory 7 is such that at least one of the opposite components 8a, 8b of the escort memory 7 improves adhesion. 19a, respectively 19b. Edge thinning is particularly easy to form, especially when the halves 8a, 8b of the protective structure 8 are also made of thin injection-molded plastic sheets as described above.

In a preferred embodiment of the invention, the edge thinning 19a, 19b comprises one or more gripping protrusions 19c according to Figures 4c and 9d. The adhesion protrusions improve the adhesion of the insert to the product itself, i.e. for example the box size 13, but when formed on the edge thinnings 19a and 19b, the adhesion protrusions 19c do not increase the external dimensions of the insert.

In a preferred embodiment of the invention, the escort memory 7 for pre-closing the opposite components 8a, 8b of the protective structure 8 encloses the fastening means 5 12a, 12b, 12c applied to the part of the components 8a, 8b corresponding to the edge thinning 19a. The fastening means preferably cover the first structural part 8a or the half-formed holes 12a and the fastening pins 12b to be fastened together by the halves 8a and 8b, which are formed as part of the second protective half-part, i.e. the structural part 8b. The fixing pins 12b are provided with flexible fixing projections 12c adapted to lock the structural parts 8a and 8b of the protective structure 8 together. The structure shown above forms an advantageous and easy-to-manufacture pre-closure of the access memory and the protective structure. Alternatively, the pre-sealing can be performed in another way, such as by ultrasonic welding or gluing. A cheap non-hermetic sealing method is sufficient for pre-sealing. The placement of the fastening means 12a, 12b in the edge-thinned area 19a, 19b is advantageous because the strength of the protective structure is the thinnest.

According to Figures 4c, 4d and 5a, in a preferred embodiment of the invention, the accompanying memory protection structure 8, 8a, 8b further comprises compression-adapted connecting means 23, 24 formed on opposite parts 25a, 8b of the protective structure 8 inside the protective structure 8. be embedded in, for example, the first structural part of the protective structure, i.e. the half 8a. The recesses 23 are shown in Fig. 4c by a broken line because they are on the neck side, i.e. inside, of the first structural part 8a of the protective structure 8, while Fig. 4c, on the other hand, shows the structural part 8a from the outside. In Figs. - 12c, because in this case the connecting means 23, 24 located inside the insert in the middle of the in-5 certificate stiffen and seal the structure of the insert.

Referring to Figures 9a and 9b, a plastic injection-molded transport or storage structure 13 according to the invention with an escort memory is preferably such that at least one of the opposite components 8a, 8b of the escort memory protection structure 8, i.e. in practice the outer edges 8c, 8d of the components with the transport or storage structure 13, i.e. the wall 14 of the box. The above structure is very easy to implement because with reference to Figures 7, 8 and 9a and 9b, the protective structure can be easily and simply placed directly against the opposite mold halves 15a, 15b through the insert core 17 in the area 18 delimited by the mold halves. is formed in wall 14. In Figures 9c and 9d, the wall thickness of the injection molded box is relatively thick with respect to the thickness of the insert. The insert thus consists of an escort memory and a protective housing 8, 8a, 8b protecting it. In the case of a thick wall 14, it may be appropriate to place the insert in the center of the wall, the insert being completely surrounded by the spray-imaged plastic. This embodiment forms the strongest fastening between the insert and the product, i.e. for example the box 13. In the preferred embodiment according to Fig. 9c, the protective structure, i.e. the insert housing structure 8, 30 8a, 8b, comprises pin-like projections 20 projecting from the protective structure 8 towards the mold 15a, 15b, by means of which the mold 15a, 15b can align the insert 20 at the desired location or symmetrically with respect to the wall they also improve the adhesion of the insert to the wall 14 of the injection mold 35. Thus, in the preferred embodiment, the protective structure 8, 8a, 8b comprises projections 20 for aligning the injection molded protective structure 8, which projections further form a marking 8 indicating the position of the protective structure 8, 8a, 8b containing the escort memory. 8a, 8b and thus the location memory of the accompanying memory 22 thus consists of the basic structure of a self-identifiable product such as a box 13, either physically or optically visible 22, the physically visible label 22 being essentially a storage or transport structure such as a box. a protrusion 20 or more in the plane of the wall 14. In the optically visible marking 22, the projections 20 comprise a warning which is clearly different from the basic structure of the product to be identified. The two methods are very easy to obtain and can withstand even heavy consumption, in contrast to the currently known solutions, in which case, in the case of the invention, the marking 22 is formed as an integral part of the identifiable transport and storage structure. According to the invention, the color is thus formed on the insert in the projections 20 and, if desired, on the myOs or, alternatively, on the sides 8c and 8d of the insert itself, whereby a darker insert can be easily seen inside the light plastic box. For the other parts shown in Figures 4c, 4d and 5a, reference is made to Figures 25a, 4b and 5, respectively.

Fig. 9d shows an embodiment in which the myds is a thick wall 14, but in this preferred embodiment the mold is provided with bidirectionally movable guide pins 21 which symmetrically align the in-30 with the certificate in the correct position. The guide pins 21 are in the position according to Fig. 9d during injection molding, after which the guide pins are pulled towards the mold 15a, 15b.

Although the invention has been described above with reference to the examples according to the accompanying drawings, it is clear that the invention is not limited thereto, but that the sitS 14 can be modified in many ways within the scope of the inventive idea set forth in the appended claims. The number and shape of the components of the transmission memory, for example the shape of the coil, may vary. Similarly, the shape of the accompanying memory protection structure may differ from the rectangular shapes shown in the figures and may be, for example, round.
