Definitions
- the invention relates to an essentially gas-tight package for packaging lumpy, possibly subdividable or subdivided packaging material with a sleeve formed from a flat, foldable packaging material, on which two edge regions of the packaging material on the inside of the packaging material within a particularly strip-shaped connection area by a releasable seal are interconnected.
- the packs according to the invention are preferably not designed exclusively as tubular bag packs.
- the two edge regions of the packaging material which are connected to one another by such a releasable seal then form the longitudinal sealing seam of the tubular bag package, referred to as Finns.
- a tubular bag pack of this type which is used in particular for packaging chocolate bars, is known from DE-OS 24 58 462.
- the longitudinal sealing seam lies in particular on a dividing notch of the chocolate bar on the rear side of the packaging envelope facing away from this notch.
- the chocolate bar is bent at this division notch so that the longitudinal sealing seam comes to rest on the outside of the crease.
- the two edge areas of the packaging material connected to each other in the longitudinal sealing seam are peeled off from the inside of the package as the seal connection is broken, with progressive kinking of the package, and finally give in Packing sleeve has an opening.
- the invention is based on the object of creating a package of the type mentioned at the beginning, in which the sealing seam in which the two packaging material edge regions are connected to one another can be arranged independently of the position of a dividing notch or location of the package material and di e can easily be opened with one hand, if necessary, without breaking the packaged goods.
- the object on which the invention is based is achieved in the pack according to the invention, which is characterized in that the packaging material edge regions which are connected to one another by sealing in a strip-shaped connecting region are turned over onto the surface of the packaging envelope, the outside of the edge region lying against the surface of the packaging envelope at least over part their surface is connected by gluing to the packaging envelope surface, and that, at least at the edge region not glued to the packaging envelope surface, the strip-shaped connecting region does not extend to the edge of the packaging material.
- the above-mentioned bonding is carried out with the packaging envelope surface advantageously by a hot melt adhesive.
- the package according to the invention is a tubular bag package, in which the packaging material edge areas connected to one another by a seal and folded over on the packaging sleeve surface form the longitudinal bag sealing seam, and in which the outside of the folded-over edge area lying against the packaging sleeve surface is only on the or in the area of the transverse sealing seams (s) of the tubular bag pack is connected to the surface of the pack casing by gluing.
- this is a tubular bag pack with longitudinal and transverse sealing seams produced by cold sealing.
- this is characterized in that in the edge region which is not glued to the surface of the package cover, between the strip-shaped connection region and the edge of the packaging material, the packaging material forms a fold in which the inside of the packaging material abuts one another. These inner sides of the packaging material are advantageously connected to one another by cold sealing.
- FIG. 1 illustrates the production of a preferred embodiment of the pack according to the invention in the form of a
- a fold 3 is first formed on a packaging material web 1 pulled off the roll, which is provided on one side with a cold sealing layer optionally applied in the profile, at an edge 2, the inside of the packaging material lying against one another in the region of the fold 3 being connected to one another by cold sealing become.
- the packaging material web 1 which is provided with an edge fold 3 in its longitudinal direction (i.e. perpendicular to the plane of the drawing in FIG. 1), is now used in the usual way to form a packaging material tube around the successively supplied packaging items, e.g. Chocolate bars 4, folded over in the direction of the arrows 5, after which the edge regions 6, 6 '(FIG. 2) of the packaging material web 1 are connected to one another to form a longitudinal sealing seam.
- FIG. 2 shows a chocolate bar 4 enclosed by the packaging material tube in a partial representation in section.
- the cold seal connection of the two edge regions 6, 6 takes place via a strip-shaped connection region 7 running in the longitudinal direction of the web (i.e. in FIG. 2 in the direction perpendicular to the plane of the drawing).
- a hot melt adhesive 8 (hot melt) and immediately afterwards the two edge areas 6, 6' connected to each other for longitudinal sealing seam are turned in the direction of arrow 10 onto the packaging envelope surface 9 and the outside of the hot melt adhesive provided Edge area 6 'is glued to the packaging envelope surface 9 before the hot melt adhesive solidifies (see FIG. 3).
- the packaging material tube enclosing the chocolate bars 4 is now provided in each case between two successive chocolate bars with two cross-sealing seams 21 running parallel to one another and divided into individual tube packs by separating cuts between these two cross-sealing seams.
- FIG. 3 The tubular bag pack produced in this way is shown in FIG. 3 in a partial representation in section and in FIG. 4 in a perspective representation.
- FIGS. 5 and 6 which - in each case in a partial representation analogous to FIG. 3 - show two different phases of the opening process.
- the edge area 6 is grasped at the fold 3, raised in the direction of the arrow 12 (FIG. 3) and pulled further in the direction of the arrow 12 ′ or 12 ′′ (FIGS. 5 and 6) 5, the edge region 6 can be seen by opening the sealing connection 7 of the longitudinal sealing seam is peeled off from the edge region 6 'until finally (FIG. 6) the two edge regions 6 and 6' are completely separated from one another.
- an increasingly widening opening 13 is formed in the packaging envelope.
- the longitudinal seam is - depending on the structure of the packaging material or the level of the sealing seam strength - in the area 14 (FIG. 4) the transverse sealing seams 21 of the fins 11 are peeled off or the packaging material in this area 14 tears on these fins 11.
- this packaging material consists of a 0.012 to 0.015 mm thick film 17 made of biaxially oriented polypropylene (OPP), a coated paper 18 with a grammage of 40 to 60 g / m 2 , a 0.007 to 0.009 mm thick aluminum film 19 and a latex-based cold adhesive coating 20 preferably applied in profile (2 to 7 g / m 2 solid).
- OPP biaxially oriented polypropylene
- Another advantageous packaging material structure consists of a 0.01 to 0.015 mm thick OPP film, to which a metallized OPP film with a thickness of 0.020 to 0.025 mm or a metallized 0.012 to 0.020 mm thick film made of polyethylene terephthalate (PETP) and attached to the inside of the pack the cold adhesive coating connects.
- PETP polyethylene terephthalate
- a composite can advantageously be chosen as the packaging material for producing a relatively inexpensive package which - starting from the outside of the pack - consists of 0.007 to 0.009 mm aluminum foil, paper with a grammage of 35 to 60 g / m 2 and the cold adhesive coating.
- FIG. 7 now shows a perspective view of a tubular bag pack in the half-opened state.
- This pack differs from the pack according to FIG. 4 in that on the outer side of the edge area 6 'with the pack casing surface 9 only within the areas indicated at 15 on the transverse sealing seams 21 of the fins 11 e.g. is connected to the packaging casing surface 9 by gluing by means of a hot melt adhesive 8 applied in a punctiform manner.
- a hot melt adhesive 8 applied in a punctiform manner.
- the package is opened by touching the end 16 of the edge area fold 3 and peeling it off in the direction of the arrow 12 ′′ ′′, advantageously being followed once or twice along the fold 3 for a complete opening.
- the peeled surfaces of the longitudinal sealing seam 7 or the transverse sealing seam 21 of a fin 11 are indicated by puncturing.
- the substantially gas-tight and easy-to-open package according to the invention preferably in the form of a tubular bag package, can advantageously be used for packaging chocolate, waffles or other products in the form of bars.
