Definitions
- the present invention relates tomaschinesbe- Q container for receiving flowable products and insbe ⁇ sondere to packaging containers for holding f nowadaysfähi ⁇ gene products having a volume of more than 200 liters.
- c has a sterile sealing outlet device with respect to the environment, which penetrates the casing and which consists of an outlet bung firmly connected to the film bag and a removal device which can be placed thereon.
- the packaging container according to the invention makes it possible / that partial quantities can be removed from a large amount of a food product over weeks without a
- the configuration of the packaging container according to the invention permits simple manufacture and preparation and safe transport of the product, the sterile seal required for maintaining the product quality
- the outlet device 35 of the film bag is guaranteed at all times by the outlet device.
- Product quantities of up to over 1000 liters can be packed without any particular difficulty.
- the outlet device is sterile sealed solely by the outlet bung.
- a closure plate made of plastic is welded into this, which is opened for removal.
- the simplest way to produce this closure plate is when the outlet bung, which is made of plastic and is essentially circular, is welded directly onto the film sack made of film.
- the advantageous embodiment of the outlet bung according to the invention provides for the outlet bung to be closed with a separate closure plate.
- connection between the outlet bung and the film of the film bag can be made considerably cheaper, which, as will be described below, enables the outlet device to be operated advantageously.
- Another advantage of the outlet bung to be preferred according to the invention is that the thickness of the closure plate can be selected independently of the thickness of the film bag. The resulting advantages are also described below. Since, according to the invention, the film bag is inserted into the covering in the folded state, it can be difficult to insert the outlet bung into the corresponding opening of the covering.
- the invention therefore provides for the outlet bung to be provided with a transverse web which is preferably arranged in the upper third of the bung. The outlet bung can be grasped at this crosspiece and inserted into the bore of the casing.
- the outlet bung can furthermore have a circumferential groove on its outer circumference, which is designed in such a way that after the bung has been carried out, it can be held in a simple manner by means of a horseshoe-shaped holding device.
- a protective cap can be placed on the outlet bung, which can also serve as a customs cap.
- an absorbent material for example a corresponding gauze pad, can be introduced, which is soaked with an insect repellent or with an insecticide.
- insects are unable to penetrate the cardboard from which the casing is constructed. However, they can succeed in piercing the relatively soft plastic of the closure plate. This is prevented by the appropriately soaked absorbent material between the protective cap and the closure plate.
- the outlet bung and the removal device must always seal the product sterile to the environment.
- the closure plate in the outlet bung must therefore be able to be opened and the removal device must be able to be placed on the outlet bung without this sterile seal being impaired.
- the invention therefore proposes to integrate a push rod provided with a knife edge into the removal device, by means of which the closure plate is pierced after the removal device has been put on. This creates the problem that the removal device can be sterilized in a suitable manner beforehand in a sterilizing bath or the like, but that the sterility can already be lost again when the removal device is placed on the outlet bung.
- the invention therefore further provides
- the sterility of the outlet device must be ensured during the entire removal time of the product. This results in the problem that the translatory movement of the push rod must be sealed in a suitable sterile manner from the environment. Furthermore, a sterile seal must be provided on the connection between the removal device and the outlet bung as well as on the other part joints of the housing of the removal device.
- the usual, known seals such as O-ring seals for sealing v against each other non-moving parts and Stopf ⁇ o book seals for relatively moving parts are not readily usable because these gaskets do not provide adequate security for a through growth of bacteria through the sealing gap.
- the invention therefore proposes to wash these seals in a constant cycle with a disinfectant liquid.
- the removal device itself takes place according to the invention through a membrane, which is fixed on one side with the push rod and on the other side with the housing 1 of the removal device and which causes a complete, sterile seal between the inside of the removal device and the surroundings.
- This membrane seal can be designed differently depending on the respective circumstances. It is crucial that the membrane enables sufficient movement of the push rod to achieve a reliable opening of the closure plate of the container. This can e.g. B.
- a bellows membrane which can be made of stainless steel or plastic, depending on the product and the sterilization process.
- a membrane to be used as a membrane which, if necessary,
- . _ loaned can be designed so that the deformation of the membrane facilitates and thus a better movement of the push rod is possible.
- the opening cutting edge is designed like a fish mouth. This means that an opening is cut out of the closure plate, which essentially the
- the essentially semi- circular design reached a particularly far downward removal opening of the film bag.
- the upper part of the closure plate can remain connected to the film bag in this embodiment, so that the closure plate forms a kind of flap valve with the partially cut-open lower part, which prevents the diaphragm pump that is used to pump out the film bag that is in the film bag contained gas, the task of which will be explained below, sucks.
- this design of the removal opening a particularly extensive emptying of the film sack is achieved, wherein, in cooperation with further design suggestions of the invention, explained below, up to 99.75 percent removal of the product is possible.
- the Invention is the design of the film bag.
- the foil bag must be designed in such a way that it optimally adapts to the generally rectangular format of the enclosing container.
- the design must allow the
- Foil sack which is placed in the wrapping in the folded state, unfolds as automatically as possible during filling, so that manual support of the unfolding by an operator is not necessary.
- the simplest way of producing such a film bag is obtained by placing two rectangular film sheets on top of one another and welding them together at the edges.
- This foil bag has the shape of a pillow, for example, if you fill it with air. Since the film bag cannot withstand the stresses caused by the product itself, the size of the wrapping must be chosen so that the film bag lies as evenly as possible on the inside of the wrapping. The inner volume of the film bag must therefore be significantly larger than the volume of the wrapper.
- the invention therefore proposes a completely different design of the film bag.
- Two sheets of film are also placed one on top of the other, but are given a special fold when they are laid one on top of the other.
- the shape of the film bag according to the invention is described below by the process of its production.
- the edges of the superimposed film webs are referred to as longitudinal or transverse edges, although the edges can have the same length.
- the folding according to the invention is achieved by first spreading out the lower film web. Then the film is folded symmetrically inwards in the longitudinal direction on both sides, so that an area remains as the bottom layer, which is approximately a quarter of the previous width of the transverse edge.
- the parts of the film web that are initially folded inward are then folded over again, in such a way that the part of the film web that is now the most uppermost and projects outward protrudes significantly above the lowest part of the film web.
- the film web then has two envelopes directed symmetrically inwards and, lying thereon, two envelopes likewise symmetrically designed on the outside.
- a correspondingly folded upper sheet is placed on this sheet in such a way that the parts of the folded sheets which face outward lie on one another.
- the sheets are welded all around, the folds being welded in at the transverse edges. There is thus an area in which the Six layers of foils lie on top of each other.
- the resulting shape of the sack can be optimally adapted to rectangular wrappings.
- the corners remaining in the corners are considerably smaller than in the embodiment described above, so that the amount of product which cannot be removed and remains in the container is significantly smaller.
- Another advantage of the design of the film bag according to the invention is that the weld seam is located in the middle of the container after the container has been filled, i.e. in other words, at a point where the pressure exerted by the product on the wrapper is only half that on the underside of the container.
- the weld seam can lie optimally against the container walls in this area, so that the pressure of the product acting on the weld seam can be passed on directly to the casing without problems for the durability of the weld seam.
- Another advantage of this form of the film bag lies in its easy unfolding.
- the foil bag straightens itself up when filling, without forming twists or the like and therefore does not require any additional effort to bring the bag into the correct shape.
- Another advantage is that the production of this film bag is particularly inexpensive to do. Since the film sack is relatively narrow in comparison to its volume due to the multiple folding, the production can be carried out on a narrow welding table despite the wide film web used, as a result of which the production is considerably cheaper. A further cost saving is achieved in that, owing to the good adaptation of the sack to the rectangular container shape, for which the same container volume is used, considerably less film is used.
- the invention proposes to insert wedge-shaped molded parts into the covering, which cause a groove-shaped inclination of the lower part of the film bag, the molded parts being designed such that the lower edge this gutter runs exactly on the outlet bung.
- these molded parts can easily be punched * out of cardboard and folded.
- the cutting die consists of an elongated rectangle, which is laterally connected in one piece to two right-angled triangles, which taper towards the shorter center line of the rectangle. The elongated rectangle extends beyond the hypotenuse of the triangles by the same amount as the length of the cathete corresponds to the side of the triangle facing away from the center line.
- a molded part is formed which is inclined in both directions and which rests on the longer cathets.
- the molded part is inclined inwards by the acute angle of the triangles and thus supports the drainage of the product.
- several such molded parts can be inserted next to one another.
- the wrapping is expediently made of cardboard.
- special care must be taken with the design, since the container size and the resulting weight of the filled container place high demands on the strength of the casing.
- the invention therefore proposes to construct the envelope from three corrugated cardboard boxes.
- the outer part of the wrapping is a cardboard box made of corrugated cardboard with a vertically running corrugation, which is usually provided with a lower and upper cover.
- Two L-shaped, right-angled pieces of cardboard are placed in this box, which lie against the four side walls of the outer box. It is essential that these two reinforcement parts are provided with a transverse shaft so that they can optimally absorb the pressure exerted by the product on the side walls.
- Foil bag container can cause problems with larger dimensions.
- the invention proposes a
- the device is e.g. made of steel bars or wood and corresponds in its outer dimensions to the inner dimensions of that on the
- the top of this device is roof-shaped in order to adapt to the course of the inclination of the molded parts.
- the device also has a milling device, the function of which will be described later.
- Outlet bung already when cutting the individual carton parts would be punched into this, since then relatively large tolerances would have to be provided in order to ensure that the individual bores lie one above the other in such a way that the outlet bung fits through. In this case, the outlet bung is not held by the box, which results in a greater load on the film near the outlet bung. This load is completely absorbed by the wrapping when the wrapping of the film bag is prepared according to the invention.
- the removal of the product from the packaging container can, as already mentioned, e.g. be carried out with a diaphragm pump.
- the problem may arise that the film bag, which collapses more and more during the removal, prevents the desired complete removal of the product.
- the invention therefore proposes to keep the film bag constantly under a slight overpressure during removal in order to avoid the film bag collapsing.
- care must be taken to ensure that the introduction of the excess pressure into the film bag does not impair the sterility of the product. It has therefore been found necessary to introduce sterile gases, such as sterilized air, nitrogen or carbon dioxide, into the film bag.
- a pressure bottle which is connected to the film bag by a sterile line via a throttle valve and an overpressure safety valve.
- the overpressure within the film bag must be such that, on the one hand, the collapse of the bag is reliably prevented, but on the other hand, the stress on the film bag by the supplied gas is not increased.

- FIG. 32 shows a simplified illustration of a device for the preparation of the film bag container according to FIGS. 10 to 22 in a side view; 33 shows the device for the preparation according to FIG. 32 in a front view;
- the packaging container consists of a wrapping 1, which encloses a film bag 2. In order to simplify transportation, the wrapping with the film bag located therein is arranged on a pallet 3. An outlet bung 4 is welded onto the film bag 2 and is connected to a removal device 5. The removal device 5 is connected to a membrane pump, not shown here, which sucks the product out of the container. A gas bottle 6 is attached to a side wall of the envelope and is connected to the film bag 2 via a line 7 by means of a pressure control device 8 (not shown here) and a pressure gauge 9.
- the gas bottle contains nitrogen, carbon dioxide or sterile air under high pressure, the selection of the gas used in each case primarily depends on the product in the container.
- the pressure of the gas bottle is reduced to a pressure of 0.05 bar via the pressure regulating devices, wherein the overpressure and thus the function of the entire device for pressurizing the film bag can be controlled by the manometer 9.
- the gas bottle remains connected to the film bag during the entire removal period. This not only has the advantage already described above that the film bag cannot collapse when removed, but also has the further advantage that a leak in the film bag is noticed immediately, since the pressure on the pressure gauge then drops accordingly. This avoids that an unnoticed leak of the film sack can lead to the product spoiling. This is particularly important if the container has a large internal volume, since otherwise an unnoticed leak can spoil a large amount of product. 1
- the pressure gauge is therefore an important indicator for the consumer of the product that the entire facility is functioning properly.
- FIGS. 2 to 6 An embodiment of an outlet bung according to the invention is shown in FIGS. 2 to 6.
- the outlet bung is made of plastic and is made in one piece. It has a tubular body 20 to which the flange 21 connects for welding the outlet bung onto the film bag 2.
- the transverse web 22 is attached, which serves for the outlet bung to be held and guided through the opening of the casing.
- a closure plate 10 is welded onto the offset surface 24 of the 5 bung. However, it can of course also be formed in one piece with the outlet bung.
- In front of the closure plate 10 is the cavity 12, into which an absorbent material soaked with a corresponding liquid can be introduced in order to prevent damage to the closure plate 10 by insects.
- the groove 23 runs around the outlet bung and serves to hold the outlet bung and for connection to the removal device.
