Description

"Device for the production and filling of transparent packs".

@ie @@ finding refers to a device for making and Filling of clear packaging, especially for a multitude of retail items, such as @@@ rauben, @@@@, @ a- @ letten. Such clear view packs consist of one hood-shaped cling film, which makes the sales type visible are, and a bottom made of peppe or the like, which for support and closure of the interior of the Kla @ transparent film is used.

Transparent packs are known as blister packs or skin packs to a large extent on the @market. You will also become completed and @lcheren Pre-packing of individual larger items such as zengen, hammers and tweezers used.

As a rule, this is a so-called disposable pack, i.e. such a pack that, after opening and removal of the object of sale is thrown away.

Among them there is also a pack with an item for sale receiving clear film part, which has a rectangular bottom part made of cardboard or the like. With bent side edges. Both parts are attached to each other in such a way that that opening the pack also destroys it- These Packs have the nac @ part, @@@ they @@@ storage @@@ and a multitude of small items, which are withdrawn in partial amounts at indefinite intervals, not suitable because the packaging will be destroyed prematurely or for further storage Laughing opening can not be closed @@@@.

If it is a packaged single item, e.g. a pair of pliers, Another disadvantage is that do: affect the subject in de closed pack @@@ or not ground in the @and genom @@@@ for testing purposes can, olme <2- cTio \ Ter1-r; 'c: iiii »% - oln ..0i t £ -' ro? bor '- £ n rC C L-, nO 0 P tbro, uo'iio, r Ci.:1,C:1t wiro-.

The purpose of the invention is for the above-mentioned way @@@ fpackung, with which cling film surrounds the floor with soitlicij unbent edges, to enable a simple creation device through which the production the packaging and its filling can be carried out by very einfacke @@ ttel, and The transparent packaging should also be reliably closed again after opening can, so that they can be used to @ ntnah @@ of subsets of the object of sale and to any long storage of the remaining amount is suitable. For hanging in a clear In shop fittings, the display packs are provided with a hanging eyelet.

According to the invention, this creation device is characterized by a horizontal guide, which is open at the top, for inserting one of a plurality of one behind the other to form a common one anyway eestrei'en merged 1C / t4 itieet-hurry, as well as an edge bending device with transport and pressing rollers which are made from tapes or the like adjustable lacquer rails supported bending, on which the selected foil edge is bent into a groove as the foil strip moves forwards.

Further advantages and mer @@@ ale of the invention result from the the following description of exemplary embodiments of the invention.

Goats in the accompanying drawings: Fig. 1 is a diagrammatic one @night of a transparent package with a rectangular bottom piece, which on the sides is encompassed by the bent edges of the transparent film strip, Lbb. 2 one schematic representation of the device according to the invention in a side view and a top view, Fig. A side view of the film strip next to a cross section through him, Fig. 4 a side view with a cross section of the floor strip, bb 5 a diagrammatic view of the bending curve.

The transparent pack 1 (Fig. 1) consists of a flat piece of foil 2, on which there is a hood-shaped bulge 3 to cover the to be packaged small sales items or the like. Raises. The side edges 4 of the flat film part 2 become from its starting position 4 ', the dash-dotted line in Figure 1 has been drawn, bent by means of the bending curves 12 so that on each side results in a groove 5 in which a rectangular bottom part 6 made of cardboard Or the like. Can be inserted, which completes the booking out 3 below.

The film strips 7 and the floor strips 6 ′ are in rolls 15 or 16 wound 1 suspended over the device according to the invention (Figure 2).

Such a Str @ if @ ns 7 (FIG. 3) is produced in a known manner Way according to the suction or pressure method, in which a heated film strips is sucked on a mold or pressed into a mold, which is for the to be produced Bulges 3 has a corresponding number of recesses.

The individual rectangular bottom parts 6 are also considered coherent strip 6 '(Figure 5) produced.

The film strips 7 are drawn into a guide 8 with a roller 9. The guide 8 consists of upright sheet metal walls 8a and 1Db, which with the help of two spindles 18 and 19 can be moved parallel to each other to one to be able to adjust the desired width of the guide 3.

The film strip 7 runs through a working section 17 on which manually insert the parts to be packed into the uXus indentations.

3 can be inserted. After running through the working section 17, the floor strip 6 ′, which runs off the roll 16, is placed on the film strip 7. One Lo serves to introduce the floor strip 6 ', a pendulum weight 22 presses the floor strip 6' onto the foil strip 7. As FIG. 1 shows, the floor strip 6 is narrower than the foil strip 7.

The edge of the film strip 7 now runs over two heating jaws that heat the bending zone of the film strip 7, so that the edge 4 is when passing through the bending curve 12 can be turned over to form a groove 5. The heating jaws 11 are at Can be folded to the side when stationary. After going through the die curve 12 the bent edge strips 4 of the film strip 7 from the transport and pressure rollers 13 or 14 pressed firmly against the floor strip 6 '. The drive of the transport rollers 13, which cause the transport processes of strings 6 'and 7, takes place via a stepless ## adjustable gear. The pressure rollers 13 are by means of adjustable springs pressed on top of the transport rollers 14. Between the transport rollers 15 and the Pressure rollers 14 run through the bent edge strips 4 from the transport. and pressure rollers 13 and 14, the now closed film strip 7 in the punching and cutting device 20 is pushed. The one with the floor strip 6 ' closed o film strip 7 is in front of and behind the known punching and cutting device 2o horizontally guided around the punching and cutting edges to reach. The tool attached in the punching and cutting device 20 punches the required hanging hole @a and cuts the respective one at the same time Blister off. Control of this facility takes place about one on The microswitch attached to the outlet side, scans directly on the flister. One The addition of transport errors is thus excluded. The now trimmed and punched transparent pack 1 now falls into the inclined drainage channel 21, which protrudes slightly from the machine so that a container can be placed underneath can.

The guide 8, the heating jaws 11, the bending curves 12, the transport and pressure rollers 13 and 14 and the guides in front of and behind the S punching and cutting device 2o are infinitely adjustable in their parallel spacing from one another, sodaPj: on this device for #production and filling of transparent blister packs different sizes can be processed.

To prevent small items from slipping out, such as S Hadeln, between the flat film part 2 and the bottom part 6 L'ii prevent a label can be glued around the back of the transparent packaging, so that part of the label chain glued to the flat Klaxsichtteil 2 and the other part of the label the back of the bottom part 6 is glued. The label part on the transparent part could carry information for type and price while on the back part of the The instructions for opening the transparent packaging could be on the label.

These transparent packs are filled and sealed. By pulling it out You can open the rectangular bottom part be so that the filled contents are exposed for complete or partial removal. To The transparent packaging can be closed again to remove any remainder keep the filling as long as you like.

The 3ode part 6 can on its lower surface and also on the upper Area in the area of the upper part 2 be printed with information that the filling objects affect. The bulge 3 can have any shape and length, and the bottom part 6 can be made much larger than the hood part.
