Blister packs are used for exhibition, Sales and storage aids for small parts, such as needles, nails, screws, dowels, Thumbtacks and many other mass-produced items that are usually only available in smaller sizes to an end user Number of items acquired. The manufacturer of the small parts - but possibly also a wholesaler the packaging of the aforementioned small parts or other mass-produced items intended for this purpose Machines or vending machines and delivers items prepackaged in this way to the sales outlets, where the packaging on prepared display areas is good for the end consumer or customer are visibly offered for self-service purposes.

In order to make the most extensive possible use of the display or hanging space for many articles, i. H. To achieve a large range of goods, the aim is to use the smallest possible dimensions of the packaging sizes, in particular through standardization, spatial

to create bo-saving packaging. The packaging should present the offered small parts visibly and be so securely closed that the removal of small parts presupposes a partial destruction of the packaging and thus such a removal is recognizable power. This is intended to protect the end consumer from purchasing incomplete offers will. It is also desirable that the package is stable enough that the end user can

Has the option of using the packaging as a storage aid for a longer or shorter period of time to be able to. Packaging that is no longer required, on the other hand, should, for the most part, be rotting and thus be largely environmentally friendly.

Previously known packaging does not yet meet all requirements. This is especially true with the simple ones and relatively cheap blister packs are reliable in terms of reusability lockable hanging storage means the case.

A known blister pack (DE-Gbm 1870775) comprises a blister card, which over a fold line running at its upper edge is folded onto one another in two layers, with on the top the lower layer has a blister hood made of transparent plastic film with its edge flanges is permanently attached by gluing. The blister card has a rectangular shape. The blister hood is also rectangular. Their total width corresponds roughly to the width of the card and their height roughly corresponds to that of the card.

The lower layer of the card here has a closed surface, while the upper layer has a Has window-like recess. The surfaces of the two layers that face each other after folding are self-adhesive. When assembling the blister pack, the peripheral, The hood with edge flanges is inserted through the recess from the inside until the upper sides the flanges come to rest on the rear adhesive surface of the upper layer. Then the lower one Layer pressed against the underside of the flanges and the packaging is glued together.

In the case of this blister pack, the lower layer must be torn open for the purpose of removing small parts will. This removes the security guaranteeing that the contents of the packaging are complete and the hood space disclosed. Means for reclosing the removal opening are missing. The remaining contents of the packaging can easily fall out at any time; this is especially the case when the end user wants to keep the opened blister pack in his work area in such a way that the purchased small parts are visibly stored and can be found again quickly.

The same disadvantages are also present when there is a tearable surface part in the lower layer would be present, which initially keeps a pre-marked removal opening closed.

The invention is accordingly based on the object of providing a suspendable blister pack of the im To create the preamble of claim 1, in which the blister hood Formed packaging space initially secured against unauthorized access, but after opening can be reliably closed again. Furthermore, a method for simpler and more economical Production of such a blister pack will be shown.

As far as the objective part of this problem is concerned, its solution consists in the characteristic one Features of claim 1.

Such packaging is from the BIister-Hauber Enclosed packing area on the removal side doubly locked or secured. The part of the manufacturer intentionally with the lower layer,

d. H. the bottom part, firmly connected and therefore in its position unchangeable intermediate floor protects the surface part arranged so that it can be torn out in the base part in such a way that it is through random or also intended pressure loads do not tear and parts of the packaged contents are lost. He follows unauthorized tearing open or tearing out of the surface part that keeps the removal opening closed, the in

ίο items stored in the hood before immediately Access protected. Further efforts to get to the contents of the packaging require the Use of tools to separate the intermediate floor from the floor part, because only after Implementation of such additional measures, the intermediate floor can be pulled up and the Removal opening is released. Such manipulations for opening the packaging are, however Avoided by shoplifters because the supervisory staff or salespeople as well as customers on such attempted theft be more attentive and be able to prove the intention to steal more reliably.

For a buyer or end user of the packaged small parts, the blister pack according to the invention has the further advantage that when the removal opening is torn out Part of the surface area of the intermediate shelves initially prevents the small parts from falling out or being poured out unintentionally prevented. The intermediate floor must then only be separated from the base part of the card in order to Pull it out of the area of the removal opening by the desired amount in the guide grooves to be able to. The loosened intermediate floor is then easily and controllably retractable, so that spilling of the content does not occur. The intermediate floor remains as an indestructible means of reclosing the removal opening received. The arrangement of the intermediate floor between the lower layer of the The blister card and the blister cover give the intermediate floor a perfect guidance that the emergence lateral gap and thus a loss of small parts.

The intermediate floor pushed into the closed position is in the one above the blister hood The suspension section of the blister card is congruent with the lower layer of the blister card. Both layers have matching hanging openings. This is the resealed blister pack can be hung up again on a nail or hook, this nail or the like. The location of the Secures the intermediate floor in the closing division. At the same time is in connection with this type of suspension ensures that even a large removal opening in the bottom part of the blister card is complete is locked and can also be kept locked when the package is hung. This means that the end user can use these, which are usually disposable and relatively cheap, after they have been completely emptied In the meantime, blister packaging has been used as a reliably closable, hanging storage medium can use.

An advantageous embodiment of the packaging is that lower edge areas of the formed scnieber-like intermediate floor from the area of the blister hood preventing locking elements are. This training initially supports the fixation of the position of the intermediate floor under the BIi-

ster hood and is also a guarantee that that the intermediate floor remains connected to the blister card at the end user.

A useful further developing feature of the invention, which allows the complete extraction of the The intermediate base excludes the blister pack consists in the fact that the upper ends of the lateral The guide grooves of the blister hood are blocked by inwardly pointing stops. The inward Pointing stops can be formed by appropriate gluing or the like.

With reference to the procedural part of the task, its solution is characterized, namely already in terms of individual packaging, through the following features:

a) First, a size is approximately twice as large as the normal size of the packaging base Folding card cut or punched and the middle fold prefabricated (e.g. scored), one card half having the shape of the bottom part with a pre-marked (perforated) removal opening as well as a hanging hole and the other half of the card the shape of the slide-like intermediate floor and also a hanging hole receives;

then the halves of the cards are folded on top of one another, in particular by machine, and if necessary bonded;
Finally, the folded card is placed on the edges of the blister hood, which already has small parts; in the process, the slide-like intermediate floor is locked and secured as a result of the attachment of the hood edges to the base part between this base part and the hood.

With this training and use of a folding card, the particular one is currently planned Standardization prescribed smallest possible dimensions of the packaging adhered to. The unfolded The folding card is flat: almost twice as large as the base of the blister card a finished packaging, but the half of the card forming the intermediate bottom arrives after the folding in an approximately congruent position to the bottom part of the blister card and thus closes a useless enlargement of the packaging. A major advantage of the aforementioned manufacturing process is that the one connected to the bottom part of the blister card on the upper edge, through the folding together on the bottom part pivoted intermediate bottom when attaching the blister hood is set captive in its end position and thus the function of a double lock and a means for reclosing the removal opening takes over.

The basic design of the folding card intended for the production of the individual blister packs is particularly suitable for the series production of blister packs. One such improved method is characterized according to the invention in that

a) for the series production of blister packs, card strips of approximately double width are used are, with - in the transverse direction opposite one another - the bottom parts in one half of the strip lined up and lined up in the other half of the strip slider-like intermediate floor punched werb)

the;

Q)

A score line forming the fold line, a fold or the like is provided between the two strip halves will;

the strip halves are folded onto one another and then placed and fastened on a tape having a corresponding number of blister hoods, whereupon the packs are separated in a separating device.
The extension of a folding card to a card strip which is about a score line provided approximately in the middle of the card strip. B. is firmly connected by gluing, leads to a considerable improvement in the cost-effectiveness of the production of the double-secured and reclosable blister packs after opening.

With regard to the manufacturing process, an improvement is achieved in that the halves of the Fold card or the folding strip with an adhesive strip before folding (at least in one half) Adhesive dots or other adhesive means and thus placed close together after folding held and placed on the blister hoods.

With the help of such an adhesive strip or similar means it is ensured that the case cards or folding strip transporting device of a packaging machine or a packaging machine the already folded card or the folded strip so securely on the edges of the blister hoods so that the intermediate floors adhere to the predetermined J5 position.

According to a further feature of the method it is provided that the halves forming the base part the folding cards or the card strips in the area of the tearable ones closing the removal opening Area parts each received a hole and that after folding the cards or the strip by means of the transport device of the packaging machine provided via the holes attached suction cups Folding cards or the card strips are lifted by suction and transported over the blister hood where the connection with the latter takes place. This training the cards or strips with the hole for the suction cup of the transport device can be used alone or in combination with the adhesive tape or the like. Can be used.

10 to 13 show the manufacture of a blister pack (Single packaging);

14 to 17 show the series production of blister packs.

The blister pack has a bottom or bottom part a hanging cardboard blister card 1. There is an off on the top of the blister card transparent plastic film existing blister hood 2 with its side edge flanges 3 and the lower edge flange 4 by gluing od. The like. Permanently attached. The blister hood encloses you Packing room 5 for small parts 6. The packing room 5 is closed on all sides, which means that unauthorized persons Removal of small parts should be prevented. Taking out small parts sets the creation a removal opening 7 (Fig. 7 and 9) in the bottom part of the blister card 1 ahead. The removal opening 7 is pre-marked along a perforated line 8 in the bottom part of the blister card and thus initially held closed by the tearable surface part 9. At the top of the tearable A tear tab 10 is provided on the surface part 9.

In the case of the blister packaging described above with regard to the basic structure, the Blister card 1 is now double-layered. This card thus has a bottom part 11 forming lower layer of rectangular basic shape and one designed as a slide-like intermediate floor 12 upper layer. Above the hood 2, this upper layer is as wide as the lower part 11 of the blister card measured. In the area covered by the blister hood, the slide-like intermediate floor has 12 a width approximately corresponding to the packing space 5 of the hood, so that the packing space through the intermediate floor is underlaid over the entire extent. The edge flanges 3 and 4 of the hood 5 are on the outside the edge boundaries of the intermediate floor 12 and are directly on the corresponding Edge areas of the lower layer of the card, namely the bottom part 11, permanently attached.

The intermediate base 12, like the base part 11 of the double-layer card 1, has a hanging hole 13 on. These holes are exactly one above the other. Instead of the circular hole, a Slotted hole may be provided. In this double-layered blister card, the upper edges 14 are the intermediate base 12 and the bottom part 11 connected in one piece and thereby for the duration of their connection against any relative shift blocked. The intermediate floor is in the area of the blister hood 5 lying section between this hood and the bottom part 11 fitted. The removal opening 7 and the surface part 9 that closes it are located in the bottom part 11 of the double-layered Card 1 and are accordingly covered by the intermediate floor and thus additionally secured.

During the completion of the blister packaging after the blister hoods have been filled with small items is thus achieved by connecting the edge flanges 3 and 4 of the hood to the corresponding ones Edge areas of the bottom part 11 of the card created a double-secured blister pack. The removal opening 7 marked in the bottom part is closed by the surface part 9 and this is additionally covered by the slide-like intermediate floor 12 fitted into the packaging, whose upper edge 14 is integrally connected to the bottom part 11 of the card. That’s the unauthorized removal of small items by shoplifters is very difficult.

At the end user, the packaging is opened in the manner shown in FIG. It will the tear tab 10 is grasped between thumb and forefinger, for example, and the surface part 9 is removed the removal opening 7 torn out. The removal opening is still through the intermediate floor 12 completely closed. With a knife, scissors or another tool 15 is then the double-layer blister card is divided on the upper edge 14 and thus the intermediate base 12 separated from the bottom part 11. This separation is shown in FIG. 8. According to FIG. 9, the intermediate floor is then

12 in the longitudinal direction up to the stops 16. In this position the removal opening is free. With only partial emptying of the packing space of the hood 5 resealing and hanging up the blister pack is desirable. There is only the intermediate floor 12 to slide back to the bottom edge flange 4 of the hood; the removal opening is then completely closed. The hanging holes

13 in both layers 11 and 12 of card 1 are congruent. The hanging nail thus secures the Slider-like intermediate floor 12 in the closed position and thus prevents during the storage time Independent opening of the packaging and small items falling out.

In the preferred embodiment shown, a double-layered FaIt card is used as the blister card. card, with the fold at the top of the card

14 is provided.

The intermediate floor 12 has lateral locking elements or guide lugs 17 at the lower end. When the intermediate floor 12 is pulled out, these lugs 17 abut against the stops 16, which at the end the edge flanges of the hood 5 are formed. It is also provided that the long sides and the The bottom sides of the blister hood receive guide grooves 18 into which the corresponding edge areas of the intermediate floor 12 engage. The lateral guide lugs 17 of the lead in these grooves Intermediate floor.

The production of an individual package is illustrated in FIGS. 10 to 13. First, the in

so Fig. 10 shown blister card 1 than about twice as Folding card sized as large as the normal size of the packaging base, cut or punched. Approximately in the middle of this folding card, the fold or fold line 19 is pre-marked, for. B. scored, folded or perforated. One half of the card has the shape of the bottom part 11 with a pre-marked removal opening 7, and also the hanging hole 13. The other half of the card is given the shape of the slide-like intermediate floor 12 and also the hanging hole 13.

In practice, the halves are now with the help of an appropriate machine or an automatic machine of the folding card according to FIG. 11 folded on top of one another. Fig. 11 shows with the dash-dotted lines the Intermediate position of the intermediate floor in the folding movement and the end position. Fig. 12 now shows the approximately square blister hood 5, which has edge flanges 3 and 4, it being at the side flanges 3 and the lower flange 4

the mounting flanges. The upper flange forms a guide flange, which the Intermediate bottom 12 engages over only tightly.

According to FIG. 13, the hood from FIG. 12 is on the bottom part 11 of the folded blister card glued on or permanently attached in some other way. In this connection process between the hood and Bottom part 11 is the intermediate bottom 12 fitted tightly between the hood and the bottom part and is thus already finally fixed in its position.

Thus, during the machine placement process of the folding card 1 on the edge flanges of the hood 5 the two halves of the card are kept close together, it is intended to te on at least one halves of the card to attach an adhesive stick 20. Instead of the adhesive strip, glue dots or adhesives can also be used other form can be provided. The adhesive strips 20 are shown in FIGS. 4 and 5, for example illustrated.

Fig. 6 shows another method for holding the halves of the folding card together during the Transportes. In this case, in the half of the folding card forming the bottom part 11 in the area of the Removal opening 7 closing tearable surface part a hole 21 is provided. After folding of the card, the transport device of the packaging machine presses a suction device over this hole 21 and thereby sucks in the half of the card underneath. The folded one then arrives in this state Blister card in the area of the hood 5 filled with small parts and is in the already described Way pressed onto the edge flanges of the hood and permanently attached.

A process for the series production of blister packs can be seen from FIGS. 14 to 17. In this case, the card strips are roughly twice as wide 22 used. Between the two halves of the strip is a score line 19 forming the fold line, a fold or the like. Provided. They are therefore located opposite one another in the transverse direction in one half of the strip the bottom parts 11 lined up closely together. In the other half of the strip, the Punched slide-like intermediate base 12. These strip halves are made in accordance with the score line 19 folded on top of one another, as shown in FIG. The BIister hoods 5 are accordingly standard in a Deep-drawn tape made of transparent plastic film, as shown in FIG. 16. According to FIG. 17 is now the folded card strip is placed on the band forming the hoods 5 and in the already described Way permanently attached. With 23 suckers are indicated in a schematic representation, the transport device belong to a packaging machine and which the folded card strips over the Transport the belt with the hoods 5. Even with this series production, between the two to one another

place a strip of glue on the sides of the strip halves

20 may be provided. However, the card strips can also have holes in the manner shown in FIG

21 received, over which the suction cups 23 are pressed and the underlying card half during the Hold up the transport. The packagings mass-produced in the above manner are in a separating device, not shown, isolated, d. H. cut apart.
