Definitions

  • the invention relates to a method for the environmentally sealed connection of a first at least partially flexible container with a second at least partially flexible container according to the preamble of claim 1, known from WO 2008/078221 ,
  • a risk of contamination of the working environment of humans and / or in general the environment and / or the corresponding burden on the people themselves is particularly given when the raw materials are present as a powdery or granular material.
  • Such raw materials must be handled in appropriate containers.
  • Containers of flexible containers or containers of sturdy racks containing flexible containers are used.
  • Foil tube sections made of endless packages, so-called endless liners, which are separated in sections depending on the portioning of the raw materials, are preferably used as flexible containers. As individually filled containers, they are available to customers who continue to use them without contamination.
  • the customer connects such containers with each other, to raw materials contained therein continuously a method available to deliver.
  • This "connecting together” is a so-called docking.
  • the connection must be made in an environmentally friendly manner to avoid contamination of the environment.
  • peelable films have long been known, which are firmly welded on one side and less firmly welded on an inside. A weld of such peelable insides can be released by pulling perpendicular to the plane of the film without damaging the walls of the film itself. Consequently, the walls in the area of the dissolved weld remain environmentally sealed.
  • chip bags for potato chips for potato chips that an opening is possible in that a weld at one end of the chip bag can be solved by lateral pulling and so the chip bag is opened clean up.
  • the object of the invention is consequently to provide a cost-effective, easy-to-use and absolutely clean, in particular contamination-free, method for the environmentally sealed connection of two flexible containers.
  • the invention enables an environmentally sealed connection, hereinafter called contamination-free docking, a first at least partially flexible container with a second at least partially flexible container. Between containers docked in such a manner without contamination, flow through a raw material in a flow direction is made possible by a method according to the invention.
  • the containers consist at least in a docking area of foils with firmly welded outer sides and inner sides which are detachably weldable with an inner seam. These are preferably containers from the above-mentioned internally peelable films. At least one of the containers is usually filled with the raw material at the beginning of the procedure. Regardless of the type of filling at least one end is welded detachable inside each container.
  • the containers to be joined together are arranged to reach a starting position opposite each other with a receiving end of the second container and a penetrating end of the first container in a docking area.
  • two alternative method steps are provided, which are carried out starting from this starting position up to a first welding in order to arrive at a comparable result of interconnected containers.
  • the receiving end is inverted, so that a receiving area arises. This is followed by insertion of the penetrating end into the receiving area.
  • the ends are or are thus interlocked.
  • the inside turned outsides of the receiving end overlap in a welding area located within the receiving area, the outsides of the penetrating end. In this position, the ends are prepared for welding.
  • either a band circulating around the ends or two bands not connected to one another are arranged in parallel direction to the course of the ends over their entire width or beyond on both sides of the container.
  • the at least one band thus covers the area between the ends of the containers on both sides and protrudes in the direction of flow beyond end sections of the ends, so that complete overlapping of the band with both ends is ensured.
  • the bands or the circulating band consist at least partially of films with firmly welded inner sides.
  • Such bands may in particular consist of the aforementioned one-sided peelable films, with a peelable outer side initially remaining unused.
  • the ends thus protrude between the bands, which can be carried out particularly advantageously as a continuous band, and are accommodated in this way in a receiving area between the bands.
  • the bands or the circumferential band overlap in a welding region which lies within the receiving region, the outer sides of both ends penetrating between the bands. In this position, the ends are prepared for welding to the bands or circulating band in the weld area.
  • the containers are connected to each other, but still closed to each other. A flow from one container into the other container is not yet possible.
  • the inner sides of the penetrating end and the inner sides of the receiving end are each detachably welded together. These releasable connections are the only obstacle to flow after welding.
  • a lateral pulling takes place at the ends.
  • the detachably welded inner sides of the ends are preferably peelable. Accordingly, the lateral pulling leads to opening the container to each other.
  • the tight welds on the outsides of the ends remain and the walls of the bundles are not damaged.
  • the containers are thus outside the dissolved inner seams after the lateral pulling hose-like and environmentally sealed together, so that the outward environmentally-friendly flow is possible.
  • the inventive method allows a hose-like connection with very simple means, namely only a device for welding, in particular heat sealing.
  • the hose-like connection between the containers docked in this way is made contamination-free or environmentally sealed.
  • the enclosed inside the container Raw material at no point in the process has the opportunity to contaminate a surrounding work environment.
  • properties of the peelable films are optimally utilized. It is particularly cleverly solved according to the first of the alternative method steps that the different properties of the inner and outer sides of the films are used by the respective sides of the two containers are selectively placed on each other and welded in a single step at a suitable location.
  • the method can advantageously be extended after the lateral drawing by a first additional welding and a first separation on a first side of the receiving region, in particular by a separating weld.
  • the first container is present after the first separation at a first separation point as at the beginning of the process separately with an end closed on the inner sides.
  • the receiving area is closed on a first side. Again, two inner sides of the film are detachably welded together.
  • the first container after the first separation again in a state in which it can be docked by the method according to the invention to a third container.
  • the initial situation is therefore restored to the first container.
  • no contamination could take place, since the first separation in the welded area of the first additional welding takes place in such a way that the detachably welded inner sides remain sealed together on both sides of a first parting line, as long as no lateral tension acts on the inner sides.
  • the ideal situation is that the weld seams can be made sufficiently wide. As a general rule a separation between two welds produced can be provided, but this carries the risk of minor contamination.
  • the method takes place, in particular in addition to the first additional welding and first separation, on a second side of the receiving area at a second separation point, a second additional welding and a second separation, in particular by a Trennsch spaung.
  • the second container is again closed clean.
  • the receiving area is present after the first and second additional welding and the first and second separation separately and closed, so that no contamination could take place here.
  • Such a closed receiving area can be disposed of separately.
  • the first and second separation is to be understood as at least partial, in particular also sectional, over the entire Ouerrough performed at the separation points separation. It is particularly advantageous to provide the separation points as perforated lines. The user can thus flexibly decide whether and when the containers are completely separated from each other, in particular when the closed receiving area is completely separated from one of the containers.
  • An inventive method is advantageously carried out with a corresponding device, in particular a device for heat sealing and / or a device for particular perforating separation or a combination of such devices.
  • FIGS. 1 to 5 are intermediate results after necessary process steps a, b.1.1, b.1.2, c and d of the method according to the invention shown according to a first embodiment, as they correspond to the numbering of FIGS. 1 to 5 follow one another.
  • FIGS. 1 . 7 . 9 and 10 or in the FIGS. 1 and 8th to 10 are intermediate results after necessary process steps a, b.2, c and d of the inventive method according to a second and a third embodiment shown as they follow one another in accordance with the aforementioned numbering of the figures.
  • the FIG. 8 is thus an alternative to FIG. 7 and to consider as a third embodiment.
  • a penetrating end 16 of a first flexible container 10 and / or a receiving end 16 'of a second flexible container 10' are changed until they are finally docked to one another.
  • the containers 10, 10 'each have firmly weldable outer sides 12 and releasably weldable inner sides 14.
  • the different properties having outer and inner sides 12, 14 are stacked in the course of the process selectively in pairs with the same properties and finally heat-sealed.
  • the flexible containers 10, 10 'each consist of a special foil on at least one end 16, 16'.
  • the special film is treated on one side so that the two sides of the film have different adhesion after heat welding. It should be generated during docking a predetermined breaking, which firmly welded only the outer sides 12 of the films, while the inner sides 16 are detachably welded. Such films are also called peelable films.
  • Both the first container 10 and the second container 10 'according to the invention have peelable inner sides 14 and firmly welded outer sides 12.
  • the receiving end 16 ' is recessed according to a first of the alternative process steps b.1.1, so that a receiving area F for the penetrating end 16 is formed.
  • the first container 10 is introduced with its penetrating end 16 into the receiving region F, so that the penetrating end 16 is located in a welding region S in the receiving end 16 '.
  • the ends 16, 16 ' are joined together according to method step c by lateral pressing and heat sealing. It is important to ensure that the heat sealing takes place only in the welding area S and not outside in an area by the two outer sides 12 of the container 10 'lie on one another because of the invagination, without being spaced from the penetrating end 16 of the first container 10 from each other are. Corresponding welds between the inner and outer sides are in the sectional views of FIGS. 4 and 5 indicated by dots. In principle, in the case of compounds according to the invention, welding is carried out without applying additional material, while at the same time the walls of the films are pressed laterally onto one another with their inner or outer sides.
  • FIG. 4 shows the after the welding c interconnected container 10 ', 10th
  • a second of the alternative method steps b.2 begins according to a second embodiment of a method according to the invention according to an arrangement a of the closed containers 16, 16 'according to FIG FIG. 1 as an alternative to method step b.1.1, b.1.2 with an arrangement b.2 of two bands 32, 34 parallel to the ends 16, 16 '.
  • FIG. 7 These are two mutually parallel bands 32, 34, which receive the ends 16, 16 'between them.
  • the bands 32, 34 have the ends 16, 16 'facing a firmly weldable surface.
  • FIG. 8 is in accordance with a third embodiment of a method according to the invention in step b.2 a continuous belt 36 is disposed around the ends 16, 16 '.
  • the band 36 may be formed by forming the bands 32, 34 FIG. 7 are connected together at both ends.
  • the circulating belt 36 can also be made as a section of an endless hose, the inside of which is firmly welded to the ends 16, 16 '.
  • the bands 32, 34, 36 from the FIGS. 7 or 8 become due to lateral pressing and heat sealing c according to FIG. 9 connected to the ends 16, 16 '. It is important to ensure that the heat sealing takes place in a welding area in which the respective end 16, 16 'of the band 32, 34, 36 is overlapped. Corresponding welds are indicated between the bands 32, 34, 36 and the outer sides 12 and between the inner sides 14 of the ends 16, 16 'in the sectional views of Figures 9 to 11 by dots. In principle, in the case of compounds according to the invention, welding is carried out without applying additional material, while at the same time the walls of the films or strips are pressed laterally onto one another with their inner and outer sides.
  • FIG. 10 shows the after the first welding c interconnected container 10 ', 10. There is a lateral pulling at the ends 16, 16' according to the method step d, thereby breaking the predetermined breaking points between the inner sides 14 of the first container 10 and between the inner sides 14 of the second container 10 ', so that the passage for the flow between the two containers 10, 10' is provided. At the same time, the fixed connection of the outer sides 12 of the containers 10, 10 'with the bands 32, 34 or the band 36 remains. The result is in FIG. 10 shown schematically.
