Definitions
- the invention relates to a packaging container according to the preamble of claim 1 and to a method for producing such a packaging container according to the preamble of claim 10.
- Packaging containers of plastic film in the form of bags or sacks are provided on a large scale and in great variety of designs for different packaging purposes.
- multilayer films in which about an inner layer of a polyolefin, especially a low melting point polyethylene ensures that the film on the side of this layer is sealable and at the same time a Moisture barrier results, while a polyester layer on the outside on airtightness, tear resistance and printability is tuned.
- the closure itself in the case of slider closures, is an extrudate which is generally not gas- and aroma-tight with a thermoplastic material, especially since the latch itself does not constitute a reliable seal.
- it can be sealed head end in such a packaging container as a slider closure with continuously connected terminal lugs, which terminal lugs can then be formed from a material which has a sufficiently high gas and / or aroma resistance and which on the other hand with a low melting, einiegelba - ren outer layer or provided with appropriate welding ribs.
- the object of the invention is therefore to design a packaging container of the known type in an embodiment with multi-layered, also provided with sufficient barrier properties plastic film so that a given gas and aroma resistance can be achieved, with such a packaging container with minimal labor and material costs and should be produced as far as possible using familiar and proven production technologies.
- this object is achieved on the one hand by a multi-packaging container according to the preamble of claim 1, starting with the characterizing features of claim 1 and on the other hand by a method according to the preamble of claim 10 starting with the characterizing features of claim 10.
- the invention is based on the finding that the sealing seams in any case, where transitions are to be overcome by the number of layers of the plastic film, represent weak points in suitable barrier materials. These lead namely with special barrier layers to greater thickness of the individual layers and thus to greater total thickness of sealing seams. In addition, the barrier layers cause greater stiffness and bulkiness of the plastic film. This is particularly noticeable on the folded edges of the gusseted walls noticeable in terms of points of failure in the top seal, then very easily enters a leak.
- This weak point can be eliminated according to the invention by a closure plug of a hot melt compound, which is provided immediately before each folding edge of the gusseted walls within the sealed seam.
- a plug of a hot melt is applied to one of the sealable surfaces, such as the fold itself or easily and reliably on one of the sealable neighboring surfaces, such as the inside of one of the main walls or an adjacent outer wall of a slider terminal lug and then in the execution melted the top seal to close the cross section of the top seal not only with existing sealable layers of the adjacent walls but in particular with this stopper.
- the hot melt compound can basically be a low melting point polyethylene (PE), as it is also used for the surface or the welding ribs of slider terminal lugs. But it can also be used another thermoplastic material low melting point.
- PE polyethylene
- the often used for the sealable inner layers of plastic film for such packaging containers and optionally also in one of the present container polyethylene is not regularly useful because it usually pulls threads and thus is difficult drop-shaped metered, and since it is also in stocking in the molten state decomposes for a long time. It is also quite advantageous if the hotmelt composition has a lower melting point than the sealable layer of the adjacent plastic films in order to achieve melting and optionally also a thin liquid in an inner region which is relatively far away from the sealing jaws of an externally gripping tool.
- FIG. 1 front view of a packaging container in a first embodiment
- Fig. 2 enlarged section along line U-II in Fig. 1 and
- Fig. 3 is a Fig. 1 corresponding view of a modified embodiment with the top side shortened side folds.
- a packaging container 1 is shown in an aroma-tight embodiment with its upper part unfilled in front view, wherein a front wall 2, with a congruent rear wall forms the two main walls of the plastic bag 1, is connected on both sides with folded in side gusseted walls 3 and 4 via lateral sealing seams 5 and 6, which in turn protrude to a folding edge 7 and 8 inwardly into the packaging container 1.
- a strip-shaped reclosure with two interlocking profile strips 10 at the upper end and with a slider 10a for opening or closing with double-ply contiguous terminal lugs 11 up to a folding edge 12 parallel to an upper edge 13 of the front wall 2 a.
- the gussets end flush with the upper edge 13 on the upper side.
- a top seal seam 14 is executed, which does not have to comply with a minimum width, but generally relatively wide for safety, preferably over the entire area between the folded edge 12 and the top edge 13 of the side seam 5 bis extends to the side seam 6.
- a cross-sectional area through the top seal 14 in a left, the gusset 4 enclosing area is shown.
- the side fold 4 is here with a half of the fold against one of the front wall 2 corresponding rear wall 2a of the packaging container, with the other half of the fold against a terminal lug 11a, which is congruent with the terminal lug 11 and related to this in the region of a lower fold 12.
- a first opening of the container for putting the terminal lugs 1 1a and 11 are separated by cutting or tearing along a predetermined line of weakness. Until then, they form a continuous wall in the head area.
- the terminal lug 11 in turn rests against the front wall 2.
- the film walls shown in cross section are all at least on one side with a sealable surface, such as a low-melting polyolefin layer such as PE and PP provided, which lies on the side facing the container interior.
- a sealable surface such as a low-melting polyolefin layer such as PE and PP provided, which lies on the side facing the container interior.
- the container rear wall 2a with the adjacent gusset half of the side gusset wall 4 is tightly sealed and sealed, while the other gusset half 4 is sealed with the container 11a directed towards the container interior half of the reclosure.
- the terminal lug 11 of the reclosure is in turn connected to the front wall 2.
- the two halves of the side gusset wall 4 are unconnected to each other, but are completed by the folding edge 8, while the upwardly unconnected expiring terminal lugs 11 a and 11 are closed at the bottom by the folding edge 12.
- the top seal seam has to overcome a problematic transition in the region in front of the fold edge 8 of the side fold wall 4, where a vertical gusset space 15 is formed.
- barrier layers that reinforce these films in thickness and / or rigidity.
- This danger is met according to the invention with a plug 16 of a hot melt, which is located within the sealed seam immediately in front of the folding edge 8 (and just before the folding edge 7) and the gusset space 15 closes off during sealing.
- the position of the plug 16 can be selected higher or lower in front of the folding edge 8, as long as it is still in the area of the head seam 14 and during sealing leads to the fact that the plug is softened and the gusset space 15 closes. Also, the size of the plug allows for choices as long as the closure is achieved. Excess material is pushed up and down during sealing.
- the plug 16 consists of a hot melt, which should be easy to process.
- it is to be selected from a group of known hotmelt compositions which are to be kept warm mechanically for a long time, can be metered well and, in particular, do not draw threads, as is customary in polyethylene for the materials intended for layers of plastic films for the packaging container area.
- the melting point of the hot melt is also chosen lower than the melting point of the sealable layers, so that premature melting and a good distribution of the plug is possible and in an internal situation in which the heat of the welding jaws must be approached by several layers.
- Such a melting temperature also does not interfere with the gradation of the melting points of the layers in the plastic films used for the packaging container in which, for example, an inner layer of polyethylene melts much lower than an outer layer of polyester, so that only the inner layer at the seal is involved.
- FIG. 3 of a packaging container 21 An embodiment shown in Fig. 3 of a packaging container 21 is largely consistent with that of Figures 1 and 2, so that the reference numerals used there are taken over.
- the gusseted walls have shortened upper edges 17, 18 that end within the top seal 14. This is a measure to close the gussets internally. However, this measure has not proved sufficient to exclude the above-described leakage in the top seal 14 before the folded edges 7 and 8.
- There escaping gas for example, can not escape upwards because the seal seam here runs continuously and after elimination of the gussets 4, the terminal lugs 11 and 11a to the main walls 2 and 2a connects tightly.
- the leakage problem solved here also occurs when the reclosure 9 is dispensed with at the top of the packaging container 1, that is to say when the packaging container is closed with the top-seal seam and remains open when the top seal seam is removed or another opening of the packaging container. Although omitted in Fig. 2, the intermediate walls 11 and 11 a, but then the leakage problem occurs between the remaining layers and is also to be solved with the plug 16.
- the plug is applied during the joining of the walls of the bag, after gussets are fixed at least on one of the main surfaces and the folded edges of the gusseted walls are fixed.
- the plug 16 is then applied in each case before the fold edges.
- the sealing of the corresponding problem area is then carried out with a seal of conventional type, without the need for special further steps or special mechanical precautions during sealing.
