Definitions

  • the invention relates to a packaging for bulk goods, such as liquids Packaging for bulk goods, such as liquids or free-flowing fine granules, the blow molded from an inner one that holds the goods to be packaged Hollow plastic body with neck-shaped closable opening and with rounded head and bottom part and from a surrounding the plastic hollow body, sleeve-shaped wrapping made of cardboard, which is on the plastic hollow body is positively fixed, with the plastic hollow body at least has an indentation on the outer edge, which during assembly for Lockable, pre-punched area of the wrapping Carton corresponds.
  • Such packaging is known from DE-A-39 21 258 by the applicant.
  • This packaging makes it possible to use the two even when the blow molding process is separate Packaging parts, namely the plastic hollow body on the one hand and the wrapper on the other hand, in the right way, in the correct position to form a secure bond assemble and also easy to dismantle after use, to dispose of both packaging components separately to be able to.
  • It is preferably very thin-walled blow molded plastic containers made of polyethylene (PE) with a very thin wall thickness in the range from 0.1 to 0.3 mm and a covering made of a bottom and lid-free support jacket Cardboard is used, but the wall thickness in the head area of the hollow plastic body for strength reasons must be dimensioned much larger.
  • PE polyethylene
  • This creation of a hollow plastic body with different areas Wall thicknesses are basically possible in a blow molding process, difficult however, the manufacturing process.
  • US-A-3 160 326 describes a package consisting of a hollow plastic body with indentations, a support jacket placed over the hollow body and an outer carton. There is a push-through opening at the top of the outer carton provided for the neck of the container. At the neck-shaped opening is a Blown ring. However, the ring is neither tapered nor is it a locking element suitable for the head area of the casing because of the push-through opening at the top of the outer carton a larger diameter than the ring Has.
  • the object of the present invention is a generic packaging to improve so that the plastic content without impairing the dimensional stability the composite packaging further reduced and the blow molding process further can be simplified, with a particularly firm connection of the composite packaging should be reached and after emptying the packaging Plastic and cardboard parts are still easy to separate.
  • This task is performed in the case of packaging of the type described at the outset solved according to the invention in that the plastic hollow body is completely thin-walled is formed and the cover made of cardboard for a positive fit on the head part of the hollow plastic body in the head area, forming a Push-through opening for the neck-shaped opening is closed, with the neck-shaped opening of the blow-molded plastic hollow body in the direction of insertion slightly tapered, as a locking element for the head area of the Enclosure trained receiving ring is blown.
  • the plastic hollow body both in the Side wall areas as in the top and bottom part thin with the same Wall thickness can be formed.
  • the head part opens into a neck-shaped Opening.
  • plastic hollow bodies made of polyethylene (PE) or also polypropylene (PP) or polyethylene terephthalate (PET)
  • PE polyethylene
  • PET polyethylene terephthalate
  • the neck-shaped opening is locked against the punched hole. This will do so achieved that at the neck-shaped opening of the blow-molded hollow plastic body Blown-on mounting ring tapers slightly conically in the direction of insertion. This leads to a particularly firm connection of the composite packaging in the Filling, transport and usage position. After emptying the packaging plastic and cardboard parts can be easily separated.
  • the manufacturability of the hollow plastic body is rounded off by a Training of the head and / or bottom part improved. So step in corner edge areas no more thin areas with undesirably thin walls.
  • the plastic material lies in the Blow molding in all areas, both in the side wall areas and in the Area of the head and bottom part evenly to the blow molds, so that no longer form unwanted thin spots in corner or edge areas.
  • the total wall thickness of the hollow plastic body advantageously only about 0.1 to 0.3 mm.
  • the present invention Hollow plastic body also in the area of the headboard with the uniform, very thin wall thickness between 0.1 and 0.3 mm, since the necessary Strength in this area also by positive engagement of the head part of the Plastic hollow body on the head area of the closed wrapping made of cardboard is achieved.
  • the weight of the plastic hollow body is a nominal volume of 1 l only approx. 15-18 g and is therefore approx. 25-40% under the weight of previously known plastic hollow bodies without complete thin-walled training.
  • the plastic hollow body therefore weighs no more than one Refill foil pouches with the same content, but offers a lot more Better handling properties, the plastic hollow body is also resealable.
  • the surface of the hollow plastic body is structured. This is used for thin-walled plastic hollow bodies in a known from DE-U-92 10 022 structured the stiffness in the trained areas increased and countered bulging. In addition a more even wall thickness profile is achieved during production and the Strength increased.
  • the neck-shaped opening is closed with a tamper-evident ring provided at the bottom.
  • the head region of the wrapping be in shape a foldable flap is formed.
  • At least the flaps of the Cover attached to the hollow plastic body with an adhesive layer.
  • the composite packaging can thus immediately after the production of the hollow plastic body assembled using a specially developed automatic assembly machine and then get to the filling line like the usual plastic bottles and be filled there on conventional systems.
  • Packaging for bulk goods can be done in the simplest way and be fed to pure material recycling.
  • Hollow plastic bodies and the cardboard wrapping can be easily removed Tear the cardboard wrapping apart slightly, separating the cardboard wrapper then the waste paper recycling, which completely emptied Plastic hollow body can be fed to plastic recycling.
  • the Separation between the two substances can be costly without the use Bring technology to consumers themselves.
  • the composite packaging generally designated 1 consists in the shown Example of a cross-sectionally essentially square hollow plastic body 2 and a support jacket 3 made of cardboard or a comparable Material.
  • FIG 1 two different head and bottom part designs of Plastic hollow body 2 shown, a rounded in the corner and edge areas Bottom part 4 and a ball-shaped head part 5, that opens into a neck-shaped closable opening 6.
  • the neck-shaped Opening 6 has an externally blown, slightly conical in the direction of insertion tapered receiving ring 7.
  • the embodiment shows in Outlet area of the rounded bottom part 4 an indentation on the outer edge 8th.
  • the wrapper 3 is shown from cardboard. This points first four side surfaces 9. At the upper edges 10 of the side surfaces 9 are each flap 11 folded inwards at an angle of 90 °, which folded in the embodiment in the form of a machine floor and are glued together. The machine floor points exactly in the middle a centered hole punch 12.
  • Figure 3 shows the composite composite packaging 1 from the plastic hollow body 2 and the cardboard wrapping 3.
  • the plastic hollow body 2 is inserted into the cardboard wrapping 3 open from below, the neck-shaped Opening 6 of the hollow plastic body 2 is blown with the receiving ring 7 inserted through the through opening 12 of the cardboard wrapper 3, then the foldable, pre-punched area 13 of the cardboard wrapper 3 folded and engages in the recess 8 on the outer edge of the plastic hollow body 2, which locks both packaging parts against each other become.
  • the plastic hollow body 2 slips out of the cardboard wrapping 3 is thus avoided.
  • the head part 5 of the hollow plastic body 2 lies after inserting the plastic hollow body 2 into the cardboard casing 3 and pushing the neck-shaped opening 6 through the push-through opening 12 form-fitting in the head area of the folded and glued flaps 11 of the cardboard wrapper 3.
  • the assembled packaging 1 is visible to the outside except for the neck-shaped opening 6 with a reclosable closure 14 is provided, no plastic parts in the position of use.
  • the cardboard wrapping 3 can, if necessary, be formed in multiple layers neck-shaped opening 6 can be located elsewhere on the plastic hollow body 2 and the push-through opening 12 is provided elsewhere in the cardboard wrapper 3 be.
  • the foldable area 13 or the entire carton wrapper 3 can additionally on the hollow plastic body 2 with an adhesive layer (e.g. hot melt) attached and secured.
  • the closure 14 used can be used in a simple design but also with an originality ring at the bottom, which at the same time the sheath 3 in the area of the push-through opening 12 under the receiving ring 7 presses.
