Description

Packaging device

The invention relates to a packaging device with a box that can be closed in a form-fitting manner with a lid, an inflatable film bag being provided in the box closed with the lid, which in its inflated state holds the packaging goods stored in the box in their position.

Such a packaging device is known from DE 38 13 309 AI.

Boxes which are in circulation and which can be closed with a lid, whether made of cardboard, plastic or metal, must also be filled with a filler which fixes and cushions the packaged goods in their position, particularly for packing piece goods in the box, for example. Such fillers today generally consist of synthetic foams such as styrofoam and the like, paper or cardboard snippets or flakes made of natural material such as popcorn or also holding and / or reinforcing shells which consist of cardboard or styrofoam . Often even a complete inner box made of synthetic foam, e.g. Styrofoam, positively inserted. Such internal packaging and support means make a significant contribution to environmental pollution since they generally have to be disposed of or recycled separately from the box and the lid.

DE-GM 66 09 223 in FIGS. 3 and 4 does not contain a membrane held on the underside of the cover however, a film bag detachably held on the underside of the lid is described. 5 shows an elastic gas container which would correspond to a foil sack, but this elastic gas container is not detachably held on the underside of the cover, but rather is provided on the bottom of the container. In addition, the elastic gas container according to FIG. 5 of DE-GM 66 09 223 has an outwardly projecting filling and emptying valve, but this is not guided through an opening in the lid, but is held in the bottom wall. The filling and emptying valves provided in accordance with FIGS. 3 and 4 are in turn not part of an elastic film bag, but only parts of the lid.

A major disadvantage of the packaging device described in DE 38 13 309 AI is that this device is used only for disposable packaging that can be automated. This is evident from the fact that the tube-like mouthpiece of the film bag must in principle be welded after being inflated, so that the film bag is not reusable. In addition, it is expressly mentioned in the publication mentioned that the packaging device described is not designed for repeated use.

The known device also has the disadvantage that the filling of the foil bag and subsequent welding of the tubular mouthpiece require a relatively complicated and expensive device. Furthermore, in the known packaging device, the film bag must first be placed over the commissioned goods in the box, whereupon the lid is placed on the still empty bag and glued, and only then is the film bag inflated and the mouthpiece must be welded. However, this does not guarantee a clear position of the film bag relative to the commission material and relative to the lid, but the position of the film bag depends on how it is inserted into the container. Therefore, proper protection of the goods to be transported is not necessarily ensured when the film bag is inflated.

Finally, it is only possible to check the tightness of the known film pouch in the inflated state and with additional devices, it not being readily possible to see whether a freshly inserted film pouch is actually tight.

In contrast, the present invention has the task of presenting a packaging device of the type described in the introduction, which can be recycled as often as desired and is therefore inexpensive and environmentally friendly. The filling and emptying of the film bag should be able to be automated in a simple manner, the film bag being intended to assume a defined, fixed position relative to the cover when the packaging device is positively closed with the lid. It should be ensured that the film bag always ensures proper protection of the goods to be transported when inflated. Finally, in the case of the packaging device according to the invention, a tightness check should be possible immediately before the lid is placed on the packaging device by means of a simple visual inspection without a special test system.

This object is achieved according to the invention in a surprisingly simple and inexpensive manner by the fact that the film bag on the underside of the lid is detachably supported and has a filling and emptying valve protruding through an opening in the cover.

In the inflated state, such a film sack lies around the packaged goods inside the box and presses forcefully on a good stored in the box, so that its position is fixed. This avoids any type of additional filling or support material, and there are no recycling or environmental problems. The film bag can advantageously be used several times and can preferably be transported and stored together with the lid. For this reason, the foil bag is held on the underside of the lid.

Because the lid forms a unitary part together with the film bag, it can also be used for other boxes to form a corresponding packaging device, the different boxes possibly also having different box depths. The packaging device according to the invention permits multiple use of the cover with a film bag as an individual part in a reusable packaging system. The lid with the foil sack detachably attached to it, like the boxes, can be used individually and in different combinations again and again. The packaging device according to the invention is thus particularly cost-saving and environmentally friendly.

For example, after the safe transport, the goods can remain in the box, while after the film bag has been evacuated, the lid can be removed and returned to a reusable transport organization.

Due to the detachability of the foil bag from the lid, one is easy interchangeability, cleanability and possible patching of a damaged film bag and thus an even longer service life of the unit is possible. This also encourages separate recycling of the film bag and lid.

The provision of an outwardly projecting filling and emptying valve through an opening in the lid enables simple, automated filling and emptying of the film bag from the outside through the lid. This ensures a very simple "handling" of the packaging system according to the invention. The possibility of filling and emptying the film bag through the valve also leads to an almost unlimited reusability of the system.

The fixation of the valve in the cover (through an opening) makes automatic filling and emptying much easier because of the defined, fixed position of the valve relative to the cover. In addition, due to its detachable holder on the lid, the film bag is always in a clear position relative to the lid and relative to the goods to be packaged when the packaging device is closed. It therefore never stands in the way and always guarantees proper protection of the goods to be transported after inflation. In addition, the foil bag is largely protected against damage when the lid-foil bag unit is handled separately due to its mounting on the lid.

A particularly simple tightness check of the film sack is made possible by evacuating the sack, directly before the bag is inflated when the box is closed It is easy to see whether the sack rests on the lid and is therefore tight if, after the film sack has been evacuated, the filling and emptying valve is closed, for example with a cap. A complex overpressure test device for the tightness of the film bag is therefore unnecessary.

The above-mentioned advantages of the packaging device according to the invention compared to the packaging device described in DE 38 13 309 A1 cannot be achieved even with the box-shaped transport container described in DE-GM 66 09 223. Although a gas container arranged below the cover is shown in FIG. 4 of this publication, this gas container does not consist of an exchangeable film bag with a filling and emptying valve protruding through the cover, but of a membrane which is pressure-tight by means of a sealing strip is attached to the lid. Such a device has nothing to do with the foil sack detachably held on the underside of the lid with a filling and emptying valve protruding through an opening in the lid. In particular, the known device does not have the advantages according to the invention. The same applies to the device shown in FIG. 5 of said publication, in which an elastic gas container is provided on the bottom of a box.

The material of the film bag according to the invention preferably consists of a flexible film which is sufficiently strong that even relatively strongly pronounced edges on the packaged goods cannot tear the film.

In a preferred embodiment of the packaging device according to the invention, the filling / emptying valve is a safety valve against excess pressure in the interior of the film bag educated. If, for example, the film bag is inflated very tightly with air, an increase in temperature can result from an increase in temperature, which is then blown off by the pressure relief valve. A pump which can be operated both as a pressure pump and as a suction pump, but which is not to be counted among the present invention, can also be provided with a pressure relief valve, so that the pressure when the film bag is inflated does not exceed a certain nominal value can. When the air is sucked out, the film sack lies in a wrinkled or bellows-like manner on the underside of the lid. In this state, the foil bag can be leaked.

The underside of the lid preferably has a fastening device for releasably fastening the film bag. Such a releasable attachment can e.g. a clamping rail which clamps the film bag on two side edges or a Velcro strip provided on the film bag and on the underside of the lid or also a strip provided directly on the film bag with push buttons which engage in corresponding counter press buttons on the underside of the lid.

The box and the lid are preferably approximately cubic or approximately cuboid in shape; the box has sloping side walls so that several empty boxes can be stacked one inside the other.

In order to make the fit of the lid on the box inexpensive and at the same time to stabilize the shape of the box, the box preferably has a peripheral edge on its upper side, which is drawn down on two opposite sides and is U-shaped in cross section. In the case of a rectangular box with longer longitudinal and shorter broad sides, the downwardly drawn edges are provided on the shorter broad sides and can serve as handle elements.

The lid preferably has a circumferential, U-shaped edge which is designed such that it completely engages around the box edge.

Inside the lid edge, the lid preferably has a recess, the dimension of which is selected such that the box bottom can be positively adjusted therein. In this way, several boxes closed with the lid can advantageously be stacked one above the other and secured against slipping sideways.

In addition, the recess of the lid is designed so that several lids can be stacked on top of one another in a form-fitting manner.

The lid and the box are preferably closed on all sides, and the lid closes the box in a dustproof and / or watertight manner. For this purpose, the edge sections on the underside of the cover can have a circumferential seal.

An edge section of the box can be provided with at least one nose protruding from the side of the box, and the lid edge resting thereon has at least one opening matched to the nose, so that the lid edge engages over the nose when closing the lid and the latter protrudes through the opening. In particular, two parallel lugs on the edge of the box and two matching openings on the edge of the lid are provided. A pair of lugs can also be designed such that they engage in corresponding openings in the lid of a box next to it, the boxes being coupled to one another.

To adapt the packaging device to the usual grid dimensions, the size of the packaging device is preferably selected in the grid of the euro pallets. Alternatively, the packaging device can also have dimensions that correspond to the mailing sizes. The material of the box and the lid preferably consists essentially of recycled plastic. The film material and the size of the inflatable film bag can, because the film bag is detachably and exchangeably attached to the lid, be selected, for example, to be adapted to the external shape and / or the weight of the goods to be packaged. A box-in-box system can be selected for sensitive packaging goods, for example refrigerated goods or liquids, the outer box serving as a cooling or collecting trough. The box can also be used for sales warehouses, as it can easily be placed side by side and one above the other with and without a lid. The box is also suitable as a storage box on the customer shelf, without having to unpack and repack. As mentioned above, the lid and the lower part of the box can be stored, used and shipped separately in the pool, and the film bag, if it can be detached from the lid, can also be stored, sent and used separately in the pool. As a rule, however, the lid is stored, shipped and used together with the foil bag attached and emptied.

A plastic, hollow rivet-like seal can be inserted through holes in the edge of the box and in the lid edge. A locking bolt that axially in the hollow rivet pre-assembled against the seal ensures that the seal cannot be removed without destroying it.

To remove the seal, a removal tool is used which contains a shaving head which shears off the seal head so that the tubular part of the seal can be pulled out of the bores.

The packaging device according to the invention thus has the following advantages:

a) Not only is there no filling material, but above all also shipping boxes in large quantities, since the new box can be used very frequently. This solves many disposal problems;

b) Coupling the boxes on pallets eliminates the need for straps, tensioning foils and shrinking foils;

c) With a watertight lid, foil packaging is not required; and

d) By means of a security seal, the box according to the invention can be sealed with the lid in such a way that unauthorized opening of the box without destroying the seal or the seals is excluded.

Further advantageous features are explained in more detail below in a preferred embodiment of the packaging device according to the invention with reference to the drawing. From the drawing figures show: 1 shows a schematic representation of a complete packaging device 1 in cross section;

1, which shows a schematic overall illustration of the packaging device 1 according to the invention in section, is a rectangular or square box 2 closed with a lid 3, which consists of a bottom 5, sloping side walls 6 and a peripheral edge 7 with a Packaged goods 9 filled, which according to the proposal is fixed in its position by an inflated film bag 10. The edge 7 is U-shaped on two opposite sides angled downwards. The film bag 10 is releasably clamped or stapled on at least two edges by fastening strips 11 _x and 11 ₂ on the underside 3 _{2 of} the cover 3, as will be explained in more detail below with reference to FIGS. 2 and 3a to 3d.

The cover 3 has a circumferential U-shaped to ge below plated wide edge, consisting _χ of sections 1, 14 _2, 14 ₃ and 14 ₄ (FIG. 2), the U-shape is bent downwards and the edge 7 overlaps the box 2. Where the lid edge with the sections 14 ₂ and 14 ₄ overlaps the edge of the box 2 which is angled downward in a U-shape, the decorative and box edges can have holes (not shown) aligned with one another for the sealing of the packaging device 1.

Further, the cover 3 on its upper side 3 _χ a Ver¬ indentation 13, whose shape and dimensions are selected so that the base 5 fits form-locking of the box 2 and further that a stackability of the cover 3 is ensured alone, in which case the Bottom 3 ₂ of another cover fits into the recess 13 of the top 3 of the cover 3.

A filling and emptying valve 12 protrudes through the middle of the wall of the cover 3, so that the film bag 10 can be inflated and also pumped out from the outside when the packaging device 1 is closed. The valve 12 is also designed as a pressure relief valve, so that an excess pressure which arises in the interior of the film bag 10 can be blown off.

All side walls 6 of the box 2 are slightly inclined, so that several empty boxes can be stacked one inside the other to save space. According to FIG. 1, the good 9 to be packaged can also be underlaid with a non-slip pad 100 with which the stabilization of the position of the packaged good 9 is further improved.

Alternatively, the inside of the bottom 5 of the box 2 can also contain an attached, non-slip pad or be roughened on this side. On all side walls 6 of the box 2, wells A _χ , 4 _{2 are also provided} for labeling fields or shipping addresses at defined locations. 2, the right and left edge portions 14 ₂ and 14 _{4 of} the cover 3 and ₂ each have two openings 15 ₁ , 15 ₂ , 15 ₃ and 15 ₄ , which, as will be explained in more detail below, of locking lugs 8 _χ and 8 _{2 of} the box 2 are penetrated. In addition, the left edge section 14 _{4 of} the cover 3 has further openings 17 ₁ and 17 ₂ which are further out.

The foil bag 10 is releasably secured in Fig. 2 at two outer sides of the underside of the cover 3 by _two mounting strips ll ll ₁ and _2. Possible variants of a detachable fastening of the film bag 10 are explained in more detail below with reference to FIGS. 3a to 3d.

In Fig. 3a, a section of the lid 3 is shown with a terminal strip II- _] _ for fastening the edge region of the film bag 10. The strip 11 ₁ has a clamping tongue 28 which clamps the film bag 10 against the underside of the cover 3 ₂ . The terminal strip 11-L can for example be screwed to the underside 3 _{2 of} the cover 3 or can also be welded or glued on. The edge of the film bag 10 can be pulled out of the cavity formed below after lifting the clamping tongue 28. 3b shows a different type of fastening of the film sack 10 to the underside 3 _{2 of} the cover 3. Co-operating Velcro strips 21 and 22 are provided on the underside of the cover 3 ₂ and on the edge of the film sack 10, respectively.

The fastening strip 1 ^ shown in FIG. 3c consists of a strip which is directly welded to the film bag 10 or integrally connected to it. The strip ll-_ has several incorporated push buttons 23, 24 which are snap pressed on corresponding counter-buttons on the underside of the cover 3. ₂ Of course, the edge of the film bag 10 adjoins the bar 11 _{luft in} an airtight _manner .

Another way of releasably attaching the Foli¬ ensacks 10 on the underside of the cover 3 is in Figure ₂ provides 3d. Darge. A flat ring or washer 27 is seen vor¬ to the valve 12 around on top of the film bag 10, ie, between the foil bag 10 and the underside of the cover ₂ and can be 3 to fix the latter fastening means by means of conventional Be¬. Of course, the fastening of the film bag 10 shown in FIG. 3d can also be combined with one of the fastening types shown in FIGS. 3a to 3c. In any case, the foil bag 10 is placed be¬ vorzugt releasably attached to the underside of the cover 3. ₂ In the pumped-out state, the material of the film bag 10 lies on the underside of the lid in a bellows-like or wrinkled manner. In this state, a tightness check of the film bag can be carried out. The size of the film sack 10 can be adapted to the inner volume of the box 2 closed with the lid 3, so that the film sack 10 in the inflated state, as shown in FIG. 1, presses against the packaged goods 9. It is not always required that the film bag 10 also laterally encloses the packaged goods 9, as shown in FIG. 1. In many cases it is sufficient if the film bag 10 exerts pressure on the upper side of the packaged goods 9 in the inflated state and presses the latter against the inside of the box bottom 5.

4 finally shows a preferably used locking catch of the cover 3 on the box 2 and a device for locking two boxes standing side by side. As already explained with reference to FIG. 2, the cover 3 has openings 15 and 17 on the right and left sides of the edges 14 ₂ and 14 ₄ which are pulled downwards. The edge 7 of the box 2 has, on the one hand, with the openings 15- _L and 15 ₂ aligned and fitting in them longer, parallel locking lugs 8 _χ and 8 ₂ and on the opposite side shorter snap lugs 16, 16 ₂ , which pass through the openings 17- _! and 17 ₂ go on. For closing the box 2, the lid 3 is initially kelrand with the DEK- 14 ₂ placed on the box edge 7, so that the longer locking lugs 8 and 8 _χ ₂ through the openings 15 ₁ and 15 ₂ in DEK- kelrand 14 ₂ go. These locking lugs 8 and 8 ₂ protrude so far beyond the outer surface of the lid 3 that they engage or hook into the openings 15 ₃ and 15 ₄ in the edge 14 _{4 of} the lid 3 of the box next to it, so that on a pair lette several boxes can be stored locked together without additional tensioning straps, tensioning foils or covering means.

When the cover 3 is closed, the shorter snap lugs 16- _L , 16 ₂ slide into the openings 11 and 17 _{2 of} the lid edge 14 ₄ by means of the sliding bevels 29 formed on the top of the snap lugs 16- _L and 16 ₂ .

4, sealing strips or profiles 26 are also shown. points to the airtight or watertight closure of box 2 and lid 3. These sealing strips 26 run around the edge of the box.

5a and 5b, a simple airbag filling and emptying valve 12 is shown in the open, closed and pressed-in state. Such valves are e.g. known for inflatable swimming animals, swimming tires and the like. The valve 12 is seated in a preferably round opening 33 of the cover 3 by means of a circumferential double bead forming a sealing collar, which forms an outer sealing collar 31 and an inner sealing collar 32. The valve socket can be pressed inwards, for example, after the airbag has been filled, a plastic flap 30 acting as a check valve being pressed into the interior of the airbag. A plug-like cap 34 closes the opening of the valve stub. To pump out or empty the valve 12, the check valve 30 is pushed back with a suction nozzle. The valve 12 is thus watertight, but releasably snapped into the opening 33 of the cover 3.

The outer dimensions of the packaging device, which is preferably matched to the grid of Euro pallets or alternatively to the grid of postal delivery sizes, is outstandingly suitable for all common packaging and storage purposes and has the essential advantage that both the box and the lid with the film bag are used several times can be used, stored and shipped separately and can be exchanged with one another with the same size. Due to the inflatable and pumpable film bag, inner fillers that are harmful to the environment or difficult to dispose of, as they have been used up to now to stabilize the position of the packaging goods in trans- port boxes were avoided.

6a shows a security seal 40 which can be plugged through bores in the box edge 7 and the lid edge 14. This seal 40 is made of plastic and, starting from a head 42, has a tubular body 41 which is like a hollow rivet and is slotted in the manner of a plastic plug and which has several resilient fastenings - claws with barbs at the end. A securing bolt 47 is preassembled in the coaxial position in the tubular body 41. The tubular body 41 of the seal 40 is inserted through the openings in the box edge 7 and in the lid edge 14, the barbs of the tubular body 41 snapping resiliently behind the box edge 7. The securing bolt 47 is then pressed inwards (on the right in FIG. 6a). In this case, bulging projections on the inner wall of the resilient fastening claws snap into an annular groove 48 of the securing bolt 47 and hold this securing bolt in its pressed-in position. The seal head 42 is connected in one piece to the tubular body 41 via a shear area 45. Centering sections 43, 44 for a removal tool are provided on the side of the seal head 42 facing the cover edge 14 and coaxially to the axis of the tubular body 41. Reference number 46 denotes a customer lettering (sender) which serves to protect against unauthorized opening and attachment of a new seal and which has the lettering of the sender printed or injected.

The sealing head can be pulled off and sheared off using suitable special pliers or a shearing and pulling tool. FIG. 6b shows a preferred pulling tool 50 in engagement with the seal head 42. The removal tool 50 has a removal bracket 52 which has a fork-shaped slot 53 at its front, open end has to reach behind the seal head 42 in the centering portion 43. At its rear end, the pull-off bar 42 has a tubular insert provided with a multi-start internal thread 56, in which a shear pin 51 provided with an external thread is screwed. The shear pin 51 has a sharp cutting shear head 54 at its front end. To shear off the seal head 42, the shear pin 51 is turned against the seal 40 by means of a wing 55 or the like, which is firmly attached to the rear end of the shear pin 51 , the cutting edges of the shaving head 54 shearing off the seal head 42 at the shearing area 45. The seal 40 can therefore only be removed by destruction, which is achieved by the action of the pull-off tool 50 shown in FIG. 6b.
