Abstract

Blister pack for packaging/displaying small articles has a suspendable cardboard base on the top surface of which a transparent plastics blister is bonded by glueing or welding along its flange. A portion of the bottom concealing a pre-marked aperture can be ripped out of the bottom. Bottom is a two-ply laminate, a base lamina being formed by the bottom ply, and an intermediate slide-type layer between the base lamina and the blister being formed by the upper lamina. The intermediate layer is connected with the corresp. edge of the base lamina to prevent longitudinal displacement. Relatively easy and inexpensive prodn. yields an attractive display which is tamperproof.

Description

Blister packaging for small parts and

Process for producing the packaging In the case of blister packs are exhibition, sales and storage aids for small parts, such as needles, nails, screws, dowels, tacks and many other mass-produced items, which, as a rule, an end consumer only purchases in small numbers. Of the The manufacturer of the small parts - but possibly also a wholesaler - runs the packaging of the aforementioned small parts or other mass-produced items for this Purpose-specific machines or automats and delivers such pre-packaged Items to the sales outlets, where the packaging is placed on prepared display areas Offered clearly visible to the end consumer or customer for self-service purposes will. To make the most extensive possible use of the display and hanging areas for many articles, i.e. for a large range of goods, one strives to through the specified minimum dimensions of the packaging sizes, in particular through shaping, to create space-saving packaging. The packaging should contain the small parts offered present visibly and be so securely closed that the removal of Small parts require a partial destruction of the packaging and thus a makes such removal recognizable. This is intended to help the end user before purchasing incomplete offers are protected. On the other hand, it is desirable that the packaging is so stable that the end user has the possibility of fl. the packaging as a storage aid for one more or to be able to use less for a long time. Packaging that is no longer required should in contrast, for the most part, they can be rotted and therefore largely environmentally friendly. Previously known packagings of the aforementioned type do not yet meet all requirements. This is particularly the case with regard to the simple and relatively cheap blister packs the usability as a reliably lockable, hanging storage aid the case.

The invention relates to a blister pack of the type which has a cardboard blister card that can be hung up as the bottom part, on whose Top a made of transparent plastic film blister hood with their Edge flanges are permanently attached by gluing, sealing, welding or the like, with a pre-marked removal opening in the blister card under the hood is provided that can be pulled out and held closed. The blister card usually has a rectangular shape. The blister hood is also rectangular, its width corresponds roughly to the width of the card, its height is slightly less than that the map. The hanging opening. is located above the blister hood in one relatively narrow or low upper section of the map.

In the case of the known blister packaging of the type required is used for the purpose of removing small parts from the bottom part of the removal opening initially closed holding area torn out. This means that it is complete the contents of the packaging guaranteeing fuse removed and the hood space exposed. Means for reclosing the removal opening are missing. The remainder of the packaging can easily fall out at any time; this is especially the case when the end user would like to keep the opened blister pack in his workspace in such a way that the purchased small parts are visibly stored and can be found again quickly permit.

The object of the invention consists in the known blister pack to improve and to show a way to produce them cheaply. It should be a cheap hangable card-like blister packaging can be created by The closed packing space formed by the transparent hood against unauthorized access initially secured twice, but after opening by means of a slide-like Intermediate floor can be reliably closed again.

According to the invention, a corresponding blister pack is thereby achieved achieved that the blister card is designed in two layers, with the lower one Position the bottom part and from the top layer one between the bottom part and the one on it attached blister hood fitted slide-like intermediate bottom are formed and the latter connected at one edge to the corresponding edge of the bottom part and is thereby locked against longitudinal displacement for the duration of the connection.

In this packaging, the one enclosed by the blister cap Packing area on the removal side, i.e. towards the bottom of the card, double-locked or secured. Intentionally on the part of the manufacturer: with the lower layer of the Blister card firmly connected and therefore in its position unchangeable intermediate floor protects the surface part arranged in the base part in such a way that it can be torn out does not tear out due to accidental or intentional pressure loads and Some of the packaged contents are lost. If there is an unauthorized opening or Tearing out the surface part that keeps the removal opening closed, so becomes due to the intermediate floor, the articles stored in the hood are still in front of immediately Access protected. Further efforts to get to the contents of the packaging, require the use of tools to separate the false floor from the Floor part, because the intermediate floor only after such additional measures have been carried out pulled up can be and the removal opening is released. Such strange manipulations for opening the packaging are so-called Shoplifters avoided because supervisors or salespeople as well as customers Attention is more likely to be drawn to such attempted theft and then to the intention to steal can also prove more reliably.

For a buyer or end user who has packaged small parts the new blister packaging has the further advantage that when you pull out the The removal opening closing surface part of the intermediate floor first of all Prevents small parts from falling out or being poured out. The intermediate floor must now only be separated from the bottom part of the card in order to get the desired To be able to pull the measure out of the area of the removal opening. The loosened slide is then easily and controllably retractable, preventing spillage of the contents does not occur. The slide-like intermediate floor remains as an indestructible medium received for reclosing the removal opening. The arrangement of the false floor between the lower layer of the blister card and the blister cover is the intermediate floor a flawless leadership, the emergence of lateral gaps and thus a loss of small parts.

The intermediate floor pushed into the closed position is in the one above The suspension section of the blister card lying on the blister hood is congruent with the the lower layer of the blister card. Both layers have matching hanging openings. The resealed blister pack is then back on a nail or Hook can be suspended, this nail od. Like. The position of the intermediate floor in the Secures the closed position, at the same time is in connection with this type of suspension ensures that even a large removal opening of the bottom part of the blister card is completely closed and also be kept locked can when the packaging is hung. This ensures that the end user this, after total emptying, mostly disposable, relatively cheap blister packaging in the meantime as a reliably lockable, hangable storage medium can use.

An advantageous embodiment of the packaging is that the blister card is designed as a double-layer folding card, the folding is provided on the upper edge of the card. This training of the blister card as Folding card leads to a simple, cheap production, the slide-like Intermediate part through the blister hood glued to the lower layer of the blister card is immediately fixed in the safety position.

It is also provided according to the invention that the slide-like Intermediate floor has transversely directed locking elements that allow complete pulling out the intermediate floor from the area of the blister hood. This training initially supports the fixing of the position of the intermediate floor under the blister hood and is also a guarantee that the intermediate floor for the end user remains connected to the blister card.

An advantageous embodiment provides that the longitudinal sides and the bottom side of the blister hood has guide grooves for the corresponding edge areas have the slide-like intermediate bottom. This training also serves to secure the position of the intermediate floor, especially to prevent the formation of lateral gaps, through which small parts could be lost if the removal opening is torn open.

A simple embodiment that allows full extraction excludes the intermediate floor from the blister packaging, consists in that the slide-like intermediate floor with lower lateral guide approaches engages in the lateral guide grooves of the blister hood and that the upper ends the lateral guide grooves of the blister hood by inwardly pointing stops are locked. The inward-facing stops can be replaced by a corresponding Gluing or the like. Be formed.

The process for making the blister pack, and already the individual packaging, is characterized by the following features: a) First of all a folding card about twice as large as the normal size of the packaging base cut or punched and the middle fold prefabricated (e.g. scored), one half of the card has the shape of the bottom part with pre-marked (perforated) Removal opening and a hanging hole and the other half of the card has the shape of the schieberartien'intermediate floor and also received a hanging hole; b) then be in particular by machine folding the halves of the cards onto one another, if necessary brought into custody; c) Lastly, the folded card is placed on the rounder of the Blister hood with small parts already in place; thereby the slide-like Intermediate floor due to the attachment of the hood edges to the floor part between this bottom part and the hood locked and secured.

In this training and use of a folding card, the in particular due to the currently planned t-shape specified smallest possible dimensions of the packaging adhered to. The unfolded folding map is almost twice in terms of area as large as the layout of the blister card of a finished packaging, However After folding, the half of the card forming the intermediate floor comes into an approximate position congruent position to the bottom part of the blister card and thus closes a useless one Enlargement of the packaging. A major advantage of the aforementioned preparation process consists in the fact that the one connected to the bottom part of the blister card on the upper edge, Intermediate floor pivoted by folding onto the base part during fastening the blister hood is fixed captive in its end position and thereby the Function of a double safety device and a means for reclosing the removal opening takes over.

The one intended for the production of the individual blister packs Basic training of the folding card is particularly suitable for series production of blister packs.

Such an improved method is characterized according to the invention in that a) for the series production of blister packs about twice as wide Card strips are used, whereby - in the transverse direction opposite one another - in one half of the strip the bottom parts are lined up and in the other half of the strip is lined up with the slider-like 7wischb8den punched will; b) a score line forming the fold line between the two halves of the strip, a fold or the like is provided; c) the strip halves folded and then placed on a tape having a corresponding number of blister caps and attached, whereupon the packages are separated in a separating device will.

The extension of a F & ltkarte to a strip of cards that around an incised line or the like provided approximately in the middle of the card strip a double-layer card strip folded up and so over a A group of blister hoods forming a band is placed on top and with the latter e.g. through Gluing is firmly connected, leads to a considerable improvement in profitability the production of the double-secured and reclosable after opening Blister packs.

This improves the manufacturing process achieved that the halves of the folding card or

of the folding strip before folding (at least in half) an adhesive strip, adhesive dots or other adhesive and thus held tightly together after folding and so on the blister hoods be put on.

With the help of such an adhesive strip or similar means ensures that the device transporting the folding cards or folding strips a packaging machine or a packaging machine that has already been folded Card or

the folded strip so securely on the edges of the blister hoods imposes that the intermediate floors adhere to the predetermined position.

According to a further feature of the method it is provided that the Bottom part forming halves of the folding cards or the card strips in the area of the the removal opening closing tearable surface parts each have a hole received and that after the folding of the cards or the strip by means of the transport device The suction cups provided over the holes of the packaging machine, the lower ones Halves of the folding cards or the card strips held up by suction and so be 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 cups the transport device can od alone or in combination with the adhesive strips. like

be used.

The blister packaging has a suspendable bottom or bottom part Cardboard blister card 1. On the top of the blister card is a transparent one Plastic film existing blister hood 2 with its side edge flanges 3 and the lower edge flange 4 by gluing or the like.

permanently attached. The blister hood encloses a packing space 5 for small parts 6. The packing space 5 is closed on all sides, whereby unauthorized removal of small parts is to be prevented. Removing Small parts sets the creation of a removal opening 7 (Fig. 7 and 9) in the bottom part the blister card 1 ahead. The removal opening 7 is along a perforated Line 8 is pre-marked in the bottom part of the blister card and thus initially through the tearable surface part 9 kept closed. At the top of the tearable A tear tab 10 is provided on the surface part 9.

When described above with regard to the basic structure Plister packaging, the blister card 1 is now made up of two layers. These The card thus has a lower layer of rectangular basic shape which forms the bottom part 11 and an upper layer designed as a slide-like intermediate floor 12. This upper one The position above the hood 2 is as wide as the lower part 11 of the blister card. 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 is underlaid by the intermediate floor in the entire wrstreckun. The edge flanges 3 and 4 of the hood 5 are on the outside of 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 bottom 12, like the bottom part 11, has the double-layered Card 1 has a hanging hole 13. These holes are exactly one above the other. Instead of A slotted hole can also be provided in the circular hole. With this double-layer The upper edges 14 of the intermediate base 12 and the base part are blister cards 11 connected in one piece and thereby against any for the duration of their connection Relative shift locked.

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 closing it are located in the bottom part 11 of the double-layer card 1 and are accordingly covered by the intermediate floor and thus additionally secured.

When the blister hoods are filled with small parts The blister pack is thus completed by connecting the edge flanges 3 and 4 of the hood with the corresponding edge areas of the bottom part 11 of the card a double-secured blister pack was created. The one pre-marked in the bottom part Removal opening 7 is closed by the surface part 9 and this is additional covered by the slide-like intermediate base 12 fitted into the packaging, whose upper edge 14 is integrally connected to the bottom part 11 of the card. In order to the unauthorized removal of small parts by shoplifters is very difficult.

At the end user, the packaging is opened in the from Fig. 7 evident way. The tear-open flap 10 is, for example, between The thumb and forefinger are detected and the surface part 9 is torn out of the removal opening 7. However, the removal opening is still complete through the intermediate floor 12 locked. With a knife, scissors or another tool 15 is then divided the double-layer blister card at the upper edge 14 and thus the Intermediate base 12 separated from base part 11. This separation is shown in FIG. 8. According to 9, the intermediate floor 12 is then shifted in a longitudinal direction up to the stops 16. In this position the removal opening is free. If the packing area is only partially emptied of the hood 5, it is desirable to reclose and hang up the blister pack. For this purpose, only the intermediate base 12 is up to the base edge flange 4 of the hood to push back; the removal opening is then completely closed. The hanging holes 13 are in both layers 11 and 12 of card 1 congruent. Of the The hanging nail thus secures the slide-like intermediate floor 12 in the closed position and thus prevents the automatic opening of the during the storage period Packaging and small parts falling out.

The preferred embodiment shown serves as a blister card a two-ply folding card, the fold being provided on the upper edge of the card 14 is.

The intermediate floor 12 has lateral locking elements at the lower end or leadership approaches 17. These approaches 17 hit when pulling out the intermediate floor 12 against the stops 16 which are formed at the end of the edge flanges of the hood 5. It is also provided that the long sides and the bottom side of the blister hood Guide grooves 18 received, in which the corresponding edge areas of the intermediate floor 12 intervene. The lateral guide lugs 17 also run in these grooves of the intermediate floor.

The production of a single package is shown in Figs.

10 to 13 illustrated. First, the blister card shown in FIG 1 folding card that is approximately twice as large as the normal size of the packaging base cut or punched. The fold is roughly in the middle of this folding map or folding line 19 pre-marked, e.g. scored, folded or perforated. One half of the card has the shape of the bottom part 11 with a pre-marked removal opening 7, furthermore the Suspension hole 13. The other half of the card takes the form of the slide-like intermediate floor 12 and also the hanging hole 13.

In practice, now with the help of an appropriate machine or a machine, the halves of the folding card according to FIG. 11 are folded onto one another. Fig. 11 shows with the dash-dotted lines the intermediate position of the in Folding movement located intermediate floor and the end position. Fig.

12 now shows the approximately square blister hood 5, which edge flanges 3 and 4, the side flanges 3 and the lower flange 4 is about the mounting flanges. The upper flange forms a guide flange, which overlaps the intermediate floor 12 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 the base part 11, the intermediate base is located 12 fits tightly between the hood and the bottom part and is therefore already final fixed in position.

So that during the machine placement process of the folding card 1 on the edge flanges of the hood 5 the two halves of the card stay close to each other, it is provided that an adhesive strip 20 is attached to at least one half of the card.

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.

Figure 6 shows another method of holding the halves together the folding card during transport. In this case, the bottom part 11 is in the forming half of the folding card in the area of the removal opening 7 closing A hole 21 is provided for the tear-out surface part. After folding the card presses the transport device of the packaging machine a suction cup over this hole 21 and thereby sucks in the underlying half of the card. Got into this state then the folded blister card in the area of the hood filled with small parts 5 and is pressed onto the edge flanges of the hood in the manner already described and permanently attached.

A process for the series production of blister packs is over FIGS. 14 to 17 can be seen. In this case, the card strips are roughly twice as wide 22 used. Between the two halves of the strip is a score line forming the fold line 19, a fold or the like. Provided. They are thus located across from each other in the transverse direction in one half of the strip, the bottom parts 11 are lined up closely together. In the other Strip half are also lined up next to the slide-like intermediate floors 12 punched. These halves of the strip are folded onto one another according to the score line 19, as shown in Fig.15. The blister hoods 5 are accordingly standard in a Deep-drawn tape made of transparent plastic film, as shown in FIG. 16. Corresponding FIG. 17 now shows the folded card strip on the band forming the hoods 5 placed and permanently attached in the manner already described. At 23 are indicated in a schematic representation of the suction device for the transport device Packaging machine include and which the folded card strips silver the Transport the belt with the hoods 5. Even with this series production, between a strip of glue 20 is provided on the sides of the strip halves that are to be placed on top of one another be. However, the card strips can also be used in the manner shown in FIG Holes 21 received through which the suckers 23 are pressed and the underlying Hold up half of the card during transport. The series in the above way Manufactured packaging is in a separating device, not shown isolated, i.e. cut apart.
