Description

Packaging and dosing system for detergents and other water treatment and / or process chemicals

The invention relates to the subject matter specified in the claims.

The invention relates in particular to novel packaging and metering systems for powdered or granular or liquid or pasty washing, cleaning, bleaching, disinfecting, preserving and / or other water treatment and / or process chemicals such as hardness stabilizers , Corrosion inhibitors, slime control agents, water softeners and the like or flocculation aids for waste water (= filling goods), comprising a specially shaped, refillable, flexible container, which is in particular bag or bag-shaped and made of water vapor-tight and transparent plastic material, a dosing or flushing device for storing or buffering the filling goods and for controlled dissolving or flushing and

Dosing the same, if necessary a measuring and control device, a holding device for attaching and adjusting the storage bag, the dosing or induction device, and if necessary the measuring and control device at the point of use, as well as, if necessary, chemically and mechanically stable receptacles for collecting and returning - port the emptied bag-shaped containers, whereby these receptacles should meet the criteria of the Dangerous Goods Ordinance.

The invention also relates to methods for flushing and dosing detergents, cleaning agents, bleaching agents, disinfectants, preservatives and / or other water treatment and / or process chemicals.

Detergents, cleaning agents, bleaching agents, disinfectants, preservatives and other water treatment chemicals have long been used as liquid, pasty, solid, lumpy and powdery or granular products. A general overview is e.g. in the publication by H. E. Tschakert, soaps, oils,

Fette, Wachsen 98, (1972), 793-801, 845-849 and ibid. 99, (1973), 3-7 contain.

More recently, the patent literature has dealt with processes for the production of shaped solid cleaning agents by filling a heated melt or solution into molds and solidifying on cooling, e.g. European patent applications 3 769 and 307 587, and German patent applications DE 35 19 353, DE 35 19 345, DE 35 19 355 and DE 36 34 812.

Due to the increasing amount of waste, there is an increased need for packaging systems that manage with as little packaging volume as possible in relation to the filling quantity. In addition, the requirement for Monoverpak materials that can be easily and reliably emptied, especially when filled with hazardous substances. One possibility for chemical products such as cleaning agents is to fill them with concentrates instead of highly diluted mixtures. In the area of cleaning agents, it should be possible to reduce the packaging requirement by factors 2 to 5. A further reduction is conceivable through the use of reusable containers, ie through refilling or recycling in single-variety recycling. As a result, reduction factors of 5 to 10 should be possible again.

DE-PS 42 04489 describes reusable containers which contain detergents or cleaning agents in the form of either compressed powder mixtures with or without a top layer or granule mixtures held by a water-soluble barrier layer. The required amount of detergent or cleaning agent is removed by spraying with water. However, the manufacture of the reusable container with detergents or cleaning agents is very complex. Furthermore, the detergent or cleaning agent product formulations are restricted, since the manufacturing process (casting, melting, pressing) can lead to reactions of individual components which are incompatible with one another. The recyclable used according to DE-PS 42 04 489

Reusable containers filled with the product and delivered to the customer must be transported back to the manufacturer after use. This requires well-organized logistics, which cannot always be accomplished.

Finally, it has to be taken into account that high return transport costs are incurred with such reusable containers and high production costs are to be estimated for the containers themselves.

The presentation in powder and granule form therefore offers manufacturers

Advantages of a very flexible recipe design and a favorable cost / performance ratio due to the relatively simple production process drive. Incompatibilities of individual ingredients, which can lead to product decomposition or reduced storage stability in the production and presentation in liquid, pasty or solid piece-like form, can be avoided more easily in the production as powdered or granular mixtures. Especially in the case of products for commercial use, which often require high product performance with very low use concentrations and short exposure times, the powdered or granular products mentioned, but also liquid or pasty products, often contain constituents which are in direct contact can cause irritation or even burns with the skin. For this reason, manufacturers of such products have been trying for a long time to offer them in a packaging form which, when used as intended, avoids the risk of direct skin contact with the products. Special dosing and dissolving devices for the products are usually required for this.

Dosing systems for machine dishwashing consisting of a dosing cartridge and a console for rinsing out the cleaning agent are also known (eg systems from Diversey GmbH, product Divopak PS in a 6 kg dosing bottle with dosing system Diverforce 2000; system from Lever Sutter, product Sumazon extra in a 4 kg dosing bottle with the matching dosing system; system from Holluscheck dosing bottle (2.5 kg).

The detergent or cleaning agents are contained in the aforementioned dosing cartridge as a powder mixture. The dosing cartridge is essentially a bottle-shaped container, which is closed at its opening with a protective screw cap. For use, the protective screw cap is removed, the bottle-shaped container with the powder or granule mixture is inserted, clamped or screwed into a suitable console, that is to say a flushing-in or injection device. By spraying with water through the sieve arranged in the container, the amount of detergent or cleaning agent required in each case, ie a concentrate, is detached and fed to the washing liquor. Common to all these systems is the disadvantage that the containers used for filling with powder have a shape similar to that of a wide-mouth bottle and therefore take up the same volume in the emptied state as in the filled state, so that both when storing the emptied container and during transport a high storage or freight volume is used either for disposal or for recycling. On the other hand, due to the design of the containers as dimensionally stable bottles, there is a relatively unfavorable mass ratio of container material. Filling content of approx. 1:20.

In the as yet unpublished German patent application P 43 13 984.1 an attempt is made to avoid these disadvantages by, inter alia, powder and granular products in a recyclable, stackable reusable container with conically designed side walls and two closable openings on the opposite sides of the cone-like Container body are filled, the smaller opening is closed with a sieve and the powder or granular products can be rinsed out of the container through this sieve by means of a suitable flushing device. Although this configuration eliminates the disadvantage existing in the aforementioned embodiments that the emptied containers cannot be stacked one inside the other during storage and transport, i.e. thus it enables a significant reduction in the storage or transport volume; the mass ratio of container material. Filling compound is still very unfavorable because of the required massive design of the container. On the other hand, here too, each individual container, like the aforementioned containers, contains a sieving device, which, due to the complex production, leads to high production costs and thus to an additional increase in the cost of products. Incidentally, it is also not appropriate from an ecological point of view to incorporate elaborate elements into a packaging system that do not serve the purpose of securing storage or transport, but rather the use by the consumer.

From DE-OS 2 518 744 a dosing device with a device is known it enables a continuous hose filled with dishwashing detergent to be passed through this metering device. There is a slotted blade in the metering device, which continuously slits open the hose and presses it into the device as it advances, deforming the hose so that the dishwashing agent can fall from the open hose into a funnel located underneath and from there into the dishwasher reached. The packaging and dosing system described in DE-OS 2 518 744 is very elaborately constructed and little or not suitable for practical use for dishwashers and washing machines, since dishwashing detergent can adhere to the blade or bake, and moreover still remains of the

Dishwashing detergent can remain in the film tube, so that it can only be insufficiently wound up on the subsequent spool.

Also known is an electronically controlled so-called permatic dosing system for powdered dishwashers, which consists of an electronic control unit and a dosing unit. The dosing device or the storage container is filled or refilled by loose goods or by portion bags. The portion packs are slit open with a blade in the dosing device and empty when the bag is pulled out of the

Storage container. This will completely destroy the portion pack. By means of a dosing mechanism, which is driven by an electric motor, the dishwashing agent is then dosed by the dosing device into a induction bowl and washed directly into the tank of the washing system with water. Although this permatic system has the advantage of simple filling, in practice it can never be completely ruled out that the operating personnel come into contact with the very aggressive cleaning agent.

The storage container of the dosing device is closed with a lid and a special powder lock and is intended to protect the powder against moisture; However, this is not the case in practice, because it was found that moisture on the dosing mechanism or in the storage container precipitation and a crusting of the cleaning powder, especially when standing for a long time overnight or on weekends.

It is also known, so-called bulk goods, i.e. Granules, agglomerates, granular and coarse pearl-shaped goods such as Fertilizers, salts, chemicals,

Pack plastic granules, feed and food in large bags with a filling volume of 300 to 2000 (300-2000 kg) liters and then transport them. These large sacks are available in many shapes and sizes, whereby in a construction form of these large sacks the sack has four hanging loops and in the bottom area for emptying various valves or side gussets / configurations (so-called four-loop sack).

A disadvantage of these large sacks filled with 300 to 2000 kg is that dosing from these containers is difficult for the consumer, i.e. usually the entire contents of the bag, for example in one

Reaction container into which this large bag can be portioned.

Another major disadvantage of all of these systems for dosing detergents and chemicals, etc., is the fact that it is generally only possible to replace the emptied bottles or cartridges or reusable containers when they are completely emptied by rinsing out the contents, and thus there is practically no reserve left to maintain the product dosage during the replacement process. In the event of delays, underdosage and process or performance disruptions (e.g. insufficiently cleaned dishes) cannot be ruled out. It is therefore desirable to have a system which, even when the completely emptied original product container is replaced, still allows a certain product supply to maintain trouble-free operation.

The invention is therefore based on the object of a system for filling, transporting, dosing and dissolving washing, cleaning, bleaching, disinfecting To provide fection, preservatives or other water treatment chemicals, with the help of which such products can be safely and without contact with human skin to the point of consumption, for example a commercial dishwasher, and fixed there, whereupon in a targeted and controlled manner the required amount of product in one Dispensed and dissolving device and can be transported from there with a liquid stream as a pre-dissolved concentrate to the workplace, for example the washing zone of a dishwasher. The system also requires that the proportion of packaging in mass is small in relation to the packaged product, that the emptied packaging can be significantly reduced in volume in a simple manner and that it can be safely stored and transported. Further requirements are that the elements of the dosing and induction system are simple and inexpensive to manufacture, because of the often restricted space at the place of use, require only a small assembly space, and can be easily and safely dismantled into individual elements for inspection, cleaning and maintenance work are and are largely stable against mechanical destruction.

According to the invention, these tasks are achieved by the packaging and dosing system for powdery and granular filling goods with the specially shaped, refillable, flexible container, the dosing or induction device

Holding device, possibly the measuring and control device and possibly the receptacle for storing and transporting the emptied container, according to claim 1; by the packaging and dosing system for liquid or pasty filling goods according to claim 19 or by the method for flushing and dosing powdered or granular or liquid or pasty

Detergents, cleaning agents, bleaching agents, disinfectants, preservatives and / or other water treatment and / or process chemicals according to claims 18 and 22, respectively.

Advantageous refinements of the invention are contained in the subclaims. Surprisingly, it has been shown that for powdered and granular fillings, the system according to the invention ensures full effectiveness of all substances of the cleaning agent or of the water treatment and / or process chemicals, this being compared without additional consumption of fresh water and cleaning powder to conventional systems is accomplished. It is essential that the personnel no longer come into contact with the detergent powder and that the flexible bags are not completely destroyed by slitting, so that they can be collected, stored and transported back to the manufacturer for refilling. Due to the transparent design of the dosing device cover or

The fill level is controllable. It is also advantageous that the water supply for supplying the spray nozzles can be controlled with the aid of the novel measuring and control device (50) so that the cleaning agent is pulsed on and an interval metering with adjustable spraying times and pause times of the cleaning agent concentrate can be achieved. This is particularly appropriate when cleaning products are used which are in solution, i.e. Conduct the electrical current well in the cleaning liquor. It is particularly advantageous that the bag (1) according to the invention has a very favorable mass ratio of container material: filling material of approximately 1:50.

Likewise, surprisingly, it has been shown that for liquid and pasty filling goods such products can be provided and dosed from a flexible container safely and without contact with human skin using a system according to claim 19.

The invention will now be explained in more detail with reference to the figures.

8 a metering and buffering device according to the invention for liquid detergents and / or water treatment and / or process chemicals with

Supply (106) and removal (1 10) spout, ventilation pipe (105) for level compensation and vacancy indicator (109). The system according to the invention can consist of the following elements:

(a) A holding device (40) for attaching and adjusting the storage bag (1, 102), the dosing or induction device (20) or the buffering and dosing device (120) and the measuring and control device (50) , consisting of mechanically and chemically stable material, preferably of stainless steel profile. The holding device (40) consists of a carrier or back element (41) with a cross member (46) attached to the upper section (42), which has holding or clamping devices, in particular height-adjustable hooks (44). The hooks are e.g. through a

The screw thread can be adjusted in height in order to enable the bag (1, 102) with the contents to be adjusted relative to the induction device. In the lower section (45) there are means for receiving the metering device (120, 20), in particular bores (47) for the housing. In another embodiment, the height of the upper cross member (44) can be adjusted by means of a rotating device on the back element or cross member, so that an adjustment of the bag suspended thereon is made possible relative to the induction unit.

Bolt locking holes for wall mounting can be provided on the back of the carrier or back element (41).

The holding device (40) can be designed as a wall or stand system.

(b) A refillable bag or sack-shaped product container (1) made of flexible, water vapor-tight material, preferably made of plastic, particularly preferably made of halogen-free plastic such as polyethylene, polypropylene, polyamide or the like or so-called natural

Plastics such as starch (s) or modified starches from blends of starch (s) with the aforementioned materials. The plastic material should preferably transparent or at least partially transparent in order to be able to recognize the fill level. A plastic material is particularly suitable, which can be welded in a manner known per se by suitable temperature effects. The bag-shaped or bag-shaped containers (1) can have any filling volume adapted to the requirements, for example approximately 500 cm ³ to approximately 1000 dm ³ . However, filling volumes between 2.5 dm ³ and about 50 dm ³ are particularly preferred for the system according to the invention, since simple handling is possible here.

The wall thickness of the flexible container wall (s) must be adapted to the stability requirements as a function of the filling quantity; e.g. With a continuous double-wall design and a filling mass of 5 kg, the outer wall thickness can be approx. 100 / m and the inner wall thickness approx. 50-70 μm. The wall thicknesses are to be optimized in such a way that reliable security during transport and use is achieved with the least possible use of material. The essential elements in the design of the bag-shaped or sack-shaped container (1) are as follows:

1 . At least in the drain part (13) double-walled side walls

(2), which enclose the longitudinal axis (L) of the container (1) and are configured in the manner of a hose in the connecting part (4) of the outlet part (13). The inner part (8) of the container wall in the lower outlet part (13) is designed in such a way that it is independent of and separate from the outer container wall (14) by sewing, gluing, binding, clipping or particularly preferably by welding can be closed at (7).

In a special embodiment, the bag-shaped or sack-shaped container (1, 102) can be designed with double walls in the entire container wall area. Furthermore, the lower part of the container (1) is tubular. In the case of the system for granular or powdery filling materials, the inner wall (8) is in a form-fitting or flush manner against the inner wall of the inlet connection (22) of the induction or dosing device, while the outer wall (14) is outside on the connection ( 22) is present.

2. On the two opposite sides of the container (1) a closure (5) at the upper edge of the container (1) and possibly a closure (7) for the inner part (8) of the container wall at the lower end of the hose-like Drain section (4). The closure (5) and possibly the closure

(7) at the top or at the bottom of the container can have been accomplished by sewing, binding, clipping or a so-called plastic zipper or particularly preferably by welding.

3. At least two hanging means incorporated at the upper edge, in particular eyelets for hanging the container (1) onto the hanging hooks of the holding device (40). These eyelets preferably consist of the same material as the walls of the container and in particular are tightly welded to it.

4. A releasable closure device (6) for jointly closing the inner (8) and the outer (14) tubular container section above the closure (7) for the inner tubular container section (4). This closure device (6) can be connected by

Clamping or, in a particularly preferred embodiment, can be achieved by a so-called clamp closure strip (cf. FIG. 5). This clamp closure bar consists of a relatively rigid, but nevertheless expandable on the open side (53) C-profile-shaped rail (51), preferably made of suitable plastic material such as polyamide and a flexible plastic cord (52) that fits into the profile or rubber. To close the double-walled tubular container section (4), the C-profile rail (51) is brought perpendicular to the hose direction on one side of the container section and from the other side the flexible cord (52) with the now fourfold flexible container walls in this rail is pressed so that a tight seal results.

Before the sack or bag-shaped container (1) is filled, in one embodiment it is closed with a closure (7) for the inner drain hose (8) and a detachable common closure (6) for the inner (8 ) and see the outer (14) hose drain, so that the lower hose section is closed; the filling material is then poured in and the upper edge of the bag-shaped or bag-shaped container at (5) is closed, in particular by welding.

In another embodiment, the upper edge at (5) of the bag-shaped or bag-shaped container can first be closed, in particular by welding, and then the container can be filled with the filling material from the other side, whereupon the releasable closure (6) is attached becomes. With this procedure, no closure is attached to the inner drain hose (8) at (7).

In the case of the system for powdered or granular filling materials, the filled bag is hung in the hooks of the holder by means of the eyelets described above, and opened if necessary in a suitable manner

Way, for example by cutting the weld seam (7), the inner wall section (8) and leads the lower tubular part of the container (4) into the inlet connection (22) such that the inner hose section (8) on the inner wall of the inlet connection (22) fits positively or flush and the outer hose section (14) rests on the outside of the inlet connection and there with a clamping device, which can be ring-shaped or semicircular, for example, or by means of springs is fixed. Then the releasable closure device (6) is released and the powder and granular product can trickle freely over the inlet connection (22) into the induction and dosing device (20). In a preferred embodiment, the sack or bag-shaped container contains approximately 5 kg of detergent. In the embodiment adapted to this bag size (5 kg bag), the filling and dosing device can hold approximately 2 kg of detergent in its powder buffer volume, so that the remaining powder product remains in the storage bag. After completely emptying, the sack-shaped or bag-shaped container (1) is detached from the inlet connection (22), taken out of the mounting hooks (44), rolled up and brought into the storage containers belonging to the system, which are to be produced according to the criteria of the dangerous goods regulation. In another embodiment, for example, plastic bags can also be used to hold the rolled-up bags (1).

(c) A induction or dosing device (20) (see FIGS. 3 and 4) for storing or buffering the powdered and granular detergents and water treatment chemicals and for inducting and dosing the same, comprising a tightly closable container ( 20) with a cover (21) and an inlet connection (22) integrated therein, a powder buffer volume (23), a tapered lower part (24), one in the tapered lower part (24) and its height Slidable sieve plate (26), which is intended to receive the substances to be dissolved, which may be in the buffer volume (23), is designed in a block-shaped manner to be screwed in under the sieve plate (26) in the tapered lower part (24) Nozzle and drain insert. The lid of the dosing and induction device (20) can be made transparent in a special embodiment. In a very particularly preferred embodiment, the housing for the dosing or induction device is also designed to be transparent. The inlet connector (22) carries one

Clamping safety device and a film detection device in the form of a snap-in sensor with mounting hole and electronic Low voltage control.

The dosing device (20) has a continuous internal screw thread (27) in the lower tapered part (24) and, if appropriate, a matching sieve insert (26) with an external screw thread (28) or with another latching mechanism. The external screw thread (28) is either an inch thread (Whitworth thread) or a metric thread according to DIN 2999. The width of the thread is 20 mm to 200 mm, preferably 25-70 mm.

The lid on the housing of the metering device can be made of metal or plastic, preferably of transparent plastic, e.g. Polyacrylate, polycarbonate, PVC exist. The diameter of the inlet connector integrated in the lid must be adapted to the diameter of the drain hose of the sack or bag-shaped container and contains one

Fixing device, e.g. a clip for the outer drain hose and a receiving hole for a bag wall filler, which is connected via an electronic circuit, e.g. a low-voltage detector that only releases the control for the water supply if and as long as the receiving hole is covered by the film of the outer drain hose, so that the sensor cannot snap into the receiving hole.

The sieve bottom insert can be made of metal, preferably stainless steel or plastic, and has on its outer circumference a screw thread adapted to the inner screw thread of the base body and

Guiding or engaging elements on both surface edges so that this sieve bottom insert can be screwed into the screw thread of the base body from below or from above and its height position can be easily changed there depending on the spray conditions required. The mesh size of the sieve must be adapted to the grain structure of the powder or granular material introduced and, on the one hand, is to prevent undissolved particles from entering the alkali drain drop, on the other hand let enough water to rinse and dissolve the required amount of product in the required time. For example, the mesh size can be approximately 0.5 mm and the wire thickness used can be approximately 0.3 mm.

The unscrewable water supply and solution drain element (30) (Fig. 4) is made as solid as possible and can be milled or assembled from individual parts and welded or injection molded from plastic. In the upper area it contains an external thread adapted to the screw thread of the base body, by means of which this element is closed

Inspection, cleaning, maintenance or repair purposes can easily be dismantled without the entire induction and dosing device having to be dismantled. This is particularly advantageous since faults can be remedied without the powder or granulate residues lying on the sieve bottom, which e.g. have to be corrosive or harmful to health.

A screw thread receptacle for spray nozzles is worked into the solid body, e.g. made of brass, stainless steel, polypropylene or Teflon and on the outside a holder for a water supply

Quick-release coupling with non-return valve, which as a "self-locking quick-release coupling" enables disassembly while operation is otherwise running. This also applies to a threaded receptacle attached to the lower end for a quick-release coupling for draining off the concentrate solution produced.

With reference to Fig. 4 for the function of the nozzle and drain insert (30), it should be stated that through the injection nozzle (31) the product quantity required in each case by controlled spraying on the screen surface on which the contents, in particular the powdered or granular cleaning product medium, are dissolved with a solvent, e.g. water. Rinsing is done automatically. The amount of each increases dosing amount of dissolved filling material, in particular of dissolved powdered or granular filling material, depending on the respective application process, controlled either by dosing time impulses and / or by the electrical conductivity in the solution contained by dissolving in water. The concentrate solution thus obtained is supplied via the drain line (62). The injection nozzle (31) in turn contains a screw thread, so that it can be screwed into the base body (33) of the water supply and solution drain element (30). In addition, a feed pipe (34) which is guided to the side is attached in the base body.

As a control device or as a measuring and regulating device (50) for the water supply and / or product supply, especially when using products which conduct the electrical current well in solution, preferably conductance-controlled control electronics with interval dosing, i.e. adjustable spraying times and pause times.

(d) In the system, known sacks, barrels, drums or boxes made of chemically and mechanically resistant material, preferably made of plastics such as polyethylene, are used as storage containers for storing and transporting the emptied sack or bag-shaped containers or polypropylene. A secure design is essential for this, so that the legal requirements, e.g. in accordance with the Dangerous Goods Ordinance, for the storage and transport of emptied sack-shaped or bag-shaped containers with possible build-up of harmful or hazardous substances.

In a further embodiment for liquid or pasty filling goods, the filled bag (102) is hung into the hook (s) of the hanging device (101) by means of one or more hanging device (s), opened when the reversibly releasable shut-off device is closed (1 15), e.g. a pinch valve, the lower end of the hose Shaped drain part (104), for example by cutting a weld, connects the tubular drain part in a liquid-tight manner to the filler nozzle (106) of the metering device (120) and then opens the reversibly releasable shut-off device. The liquid product contained in the flexible storage container (102) empties, especially after

Loosen the screw cap on the filler neck (100) automatically up to level compensation by means of the ventilation pipe (105) in the hollow cylinder (108) of the metering device. A particular advantage of this embodiment lies in the fact that, by suitably dimensioning the volume or the height of the hollow cylinder (108) after the vacancy indicator device (109) has responded, there is still a sufficient supply of filling material for the flexible container to be replaced and a new one connected filled storage container required period is available.

Any contained in the system for liquid or pasty filling goods

Mixing device is preferably designed according to the injector system, in which, depending on the amount of diluent medium flowing in, e.g. Water, an adjustable proportional amount of liquid or pasty filling materials is added and mixed with the diluent. It is a flow or volume of

The amount of paste-like or liquid filling materials supplied to the dilution medium is regulated independently of the amount of the dilution medium supplied or flowing in.

The system for liquid or pasty filling goods also contains a holding device (40) for attaching and adjusting the flexible filling material container (102) as well as the metering and admixing device and possibly the measuring and control device (50). The above general description of the refillable bag or sack-shaped container (1) also applies here analogously to the container (102), which is preferably of double-walled design.

The above description for the measuring and control device (50) and the receptacle for storage and transport of the emptied Containers also apply to the system for liquid or pasty filling goods.

The containers (1, 102) according to the invention can be equipped with filling goods which are solid, powdery and / or granular and / or liquid and / or pasty washing, cleaning, bleaching, disinfecting and / or

Preservatives and / or other water treatment agents and / or process chemicals include. Conventional fillings known to the average person skilled in the art are used, e.g. in DE-PS 4 204 489 cited above. However, powdered and / or granular fillings are particularly preferred. Water-soluble, basic or acidic substances, such as e.g. Caustic soda or citric acid can be used.

The following are examples of compositions for the fillings (each in% by weight).

With the help of the packaging and dosing system described above, viscous and pasty auxiliaries, cleaning agents and in particular skin treatment creams can also be packaged and dosed. For this purpose, the metering device must be designed specifically for liquid and pasty products by providing special means such as flaps, flap valves, extrusion presses and extrusion devices. Furthermore, in the case of pasty filling goods, a squeezing press for the bag (1), i.e. one or two squeeze rollers can be provided so that the pasty filling material is transported in the direction of the metering device.

A further advantageous embodiment of the invention, in particular in the system for liquid, viscous or pasty filling goods, consists in the fact that a preferably transparent, movable shielding or protective device, for example a protective shield made of unbreakable, chemical-resistant plastic material, surrounds the entire metering system is attached around in order to avoid endangering the operating personnel as a result of mechanical damage to the bag-shaped or bag-shaped flexible storage containers.
