Definitions

  • the invention relates to a packaging for plasticizers with side walls, bottom and top wall, in which at least that area of the top wall, to which an opening device is attached, is provided with thermoformed plastic and the opening device has an inner part and a cover cap.
  • the invention also relates to a method for manufacturing such packaging and a device for performing this method.
  • cuboid packaging made from a web of plastic coated paper, e.g. either have a substantially flat top wall or a top wall with a gable shape.
  • opening devices have a cylindrical inner part with an external thread and a cover cap with an internal thread. To open, the user unscrews the cover cap and the inner part is open at the top, so that the contents can be poured out or poured out.
  • opening devices of this type seal off the end of the inner part that is open at the top via a circular edge and then tend to leak if the sealing ring has a defect or is not structurally engaged with a good sealing seat.
  • opening devices of the known type are often complex and therefore expensive to manufacture.
  • Elastic packs are also known, the side walls of which consist of paper coated with plastic, but the lid and base of which consist of thermoplastic material without a carrier material.
  • opening devices are already molded in one piece with the top wall, generally by an injection molding process, without the plastic being thermoformable.
  • Other opening devices are not perfectly liquid-tight because, in the case of a cheaply produced cover cap, it is pressed only fleetingly into a collar as the inner part, with the risk of gaps remaining. In the case of elaborately manufactured opening devices, inexpensive production is not possible.
  • the object of the invention is therefore to provide a packaging, a method and a device for producing a packaging of the type mentioned at the outset, in which the opening device is guaranteed to be liquid-tight, easy to open and at the same time simple and inexpensive to produce before first opening.
  • the inner part of the opening device is formed in one piece with the plastic region of the upper wall from this region by thermoforming and consists of the same plastic and has an approximately cylindrical or conical shape.
  • the invention is based on the idea of producing the top wall at least in a certain area from thermoformed plastic, with the opening device being provided in this area with plastic.
  • the material of which can be deep-drawn, thermoforming and in particular deep-drawing can cause a change in the design of the wall so that the inner part of the opening device is formed.
  • this is evidently made of the same plastic as the plastic area of the top wall and is integral with it.
  • the shape of this inner part is cylindrical or conical or frustoconical. The person skilled in the art can then use other methods known per se for designing a practical opening device.
  • thermoforming or deep-drawing of the opening device is of course also successful if the entire top wall is made of plastic without a carrier material, in particular if this plastic is thermoformable Plastic are made:
  • the cylinder of the inner part of the opening device is closed to the outside by a disk, communicates with the inside of the packaging and has an external thread on the side, onto which the cover cap can be screwed.
  • an inner part with an external thread it is expedient to provide the shape of this inner part similar to a cylinder in order to unscrew a cover cap to facilitate with internal thread.
  • the inner part of the opening device according to the invention created by deep-drawing or thermoforming is guaranteed to be liquid-tight before the first opening, especially if the cylinder of the inner part is closed towards the outside.
  • the plastic area of the upper wall is deformed so that it remains closed so that when the cylindrical inner part is finished, it looks closed on the top outside as if it were a disk.
  • the inner part has never been open at the top, but is formed by the configuration as a cylinder by the measures according to the invention.
  • the inner volume of this cylindrical inner part is then also evidently connected to the inside of the packaging, so that after the upper disc has been separated off, a pouring opening results and the filling material flows through the cylindrical inner part of the opening device during pouring
  • Proposals have already been considered to provide simple devices for opening the opening device according to the invention by attaching one or more knives inside the cover cap, i.e. to cut the window so that the end user finds an extremely easy opening.
  • the bottom of the package has a recess which extends into the interior of the package.
  • a major disadvantage of known plasticizer packs with the opening device protruding outwards and upwards from the upper wall is frequently that such packs are difficult to stack or valuable transport volume is lost. So that on the one hand the stackability of plastic packaging is improved by using essentially flat top walls, but on the other hand the opening device according to the invention can even be used when the opening device projects outwards beyond the top wall and thus also beyond the outer contour of the packaging above, the recess in Floor provided. If you stack one package over the other, the opening device protruding upwards from the top wall can be accommodated in the recess in the bottom of the package arranged above it. This ensures perfect stackability
  • the recess is arranged near one side of the bottom of the pack, which is essentially flat, and has the shape and dimensions of the outer contour of the opening device, which is correspondingly provided near one side of the essentially flat top.
  • the superplasticizer has, for example, a cuboid shape with a substantially flat top wall and a substantially flat bottom.
  • cover cap is attached or screwed onto the inner part of the packaging below and that the recess in the floor of the packaging located above is so large that the entire opening device, ie the cover cap placed on the inner part can also be accommodated in the recess in the base.
  • an opening device includes both an inner part with and one without a thread, the cover cap then being designed with or without an internal thread. It is only important that the cover cap comes into engagement with the inner part from the outside in such a way that the inner part is encompassed by the cover cap. In contrast to the known opening devices, it is precisely a feature of the invention that the inner part is not sealed by the cover cap must, because the inner part is closed to the outside by the above-mentioned disc.
  • the invention also relates to a method for producing an eluent pack of the type mentioned at the outset.
  • the method according to the invention provides that the inner part of the opening device is made in one piece by deep drawing from the area of the wall made of plastic is formed outwardly above and after removal from the mold a cover cap is placed, preferably during and / or after the deep-drawing or / s of the inner part, a recess is produced from the substantially flat-shaped bottom by deep-drawing into the interior of the package.
  • the most important feature of the method according to the invention is thermoforming, preferably by deep drawing, of the inner part of the opening device from the area of the upper wall of the packaging made of plastic.
  • an opening device is created which the consumer can open and close easily and well. This is particularly successful when the opening device protrudes from the top wall. It is therefore expedient and preferred if, according to the invention, the inner part is shaped outwards from the top wall. After the top wall thus finished, ie after the product has been removed from the mold, a cover cap is put on, be it that it is pressed on by clamping, or be it that it is screwed on with the aid of shaped threads. The fitting of the cover cap should be understood in this sense.
  • the thermoforming or deep drawing of such an inner part automatically results in an inner part which is closed at the top and which - if it has the shape of a cylinder - is closed at the top by a kind of disk. It goes without saying that with plug-in or other pressure connections between the cover cap and the inner part, other designs of the inner part and also the inside of the cover cap are possible, for example oval or elliptical structures in cross section.
  • a recess is also produced from the bottom at the same time by thermoforming or deep-drawing, because then the preferred embodiment of an eluent pack described above can be produced which: on the one hand, it can be stacked well and, on the other hand, it can also be produced without bulging walls if the opening device and or the recess in the bottom are molded after filling.
  • the entire packaging is produced from a sheet of thermoformed plastic.
  • the plastic can be used to produce webs with a thickness of 0.5 to 3 mm, preferably 1 to 2 mm.
  • a thermoplastic is advantageously used as the plastic, preferably polypropylene, propene comopolymer or ethylene-propene copolymer. This plastic is also known in the art as polypropene.
  • the packaging according to the invention then consists of perfectly reprocessable and easily rotten parts and materials.
  • the plastic material for example the polypropene, can also be filled, the fillers here being chalk, mica, talc, plaster or the like. In practice, filling levels of up to 70%, preferably 60%, have proven to be favorable.
  • filled plastic materials of this type are easily rotted on the one hand, can of course also be easily reprocessed or recycled using simple methods and on the other hand do not impair the properties of a plastic, so that such filled plastic materials are particularly deep-drawable and also sealable.
  • Such packaging made from a sheet of thermoformable plastic has the further advantage that, according to the invention, the area of the upper wall consisting of plastic is heated after the filling of the packaging with flow agent for the thermoforming process.
  • the conventional machines and the known methods can even be used in a simplified manner to the extent that no measures for the provision of opening devices have to be taken and observed.
  • a plasticizer pack can be filled and manufactured to be perfectly liquid-tight, preferably even gas-tight, which is not provided with any opening device.
  • the opening device is created by the method according to the invention, rather, after filling, that the upper wall, which is then made entirely of plastic material, is heated to a temperature sufficient for deep-drawing and then the opening device is created in the manner described above by deep-drawing and fitting the cover cap.
  • the invention relates to a device for producing a plastic packaging with essentially flat side walls, bottom and top wall, in which at least that area of the top wall to which an opening device is attached is provided with thermoformed plastic and the opening device has an inner part and a cover cap
  • the manufacturing device is characterized in that an upper tool with an outwardly open recess with a shape corresponding to the outer contour of the inner part of the opening device is provided movably relative to the upper wall of the packaging and that the recess has openings with the fluid lines leading outside the upper tool are connected.
  • the manufacturing device is thus characterized by an upper tool which has a recess provided with openings.
  • the purpose of the depression is to form a deep-drawing mold into which the softened plastic is drawn in via a vacuum using the openings, with the result that the plastic material in the heated plastic area lies against the inner surface of the depression, as a result of which the inner part of the opening device is formed by itself .
  • the top tool is related to the product to be machined, i.e. the packaging, arranged movably so that a relative movement between the upper wall of the packaging on the one hand and the upper tool on the other hand is always possible
  • the design of the depression is important with regard to its inner surfaces, since these form the inner wall of the deep-drawing tool and the softened plastic bears against it to form the inner part of the opening device.
  • the shape of the recess must therefore correspond to the desired product, i.e. correspond to the opening device. It is important that the recess of the upper tool is placed at that point on the upper wall of the packaging at which the opening device is to be formed, ie where the heated plastic area is located. This area must therefore come to lie around the depression when the upper tool is moved relative to the upper wall of the packaging.
  • the openings in the recess of the upper tool must be small enough that no annoying marks occur when the plastic material is applied to the inner wall of the recess.
  • a sufficient number of very small openings with a diameter of e.g. 1/10 mm to 5/10 mm is sufficient to extract a sufficient volume of gas, preferably air, in a sufficiently short time so that the deep-drawing process can be carried out quickly and effectively.
  • the fluid lines leading outside of the upper tool are particularly useful preferred embodiments for conveying air, both conveying directions being possible here, depending on whether vacuum is to be applied behind the depression or compressed air is to be introduced in the opposite direction. It is also conceivable to pump liquids that have not yet been used in previous attempts.
  • the inner part of the opening device is to be made essentially cylindrical and preferably if the inner part of the opening device is to carry an external thread, it is expedient to design the upper tool in two parts in order to ensure easy removal from the mold after deep drawing.
  • a lower tool with a projection projecting outwards towards the upper tool with a shape corresponding to the outer contour of the opening device relative to the bottom of the packaging is provided movably and if the extension has openings which are connected to fluid lines leading outside the lower tool.
  • the packaging is moved between the upper and lower tools, then the upper tool is moved against the upper wall and the lower tool against the bottom of the packaging, vacuum is applied to the depression and compressed air is introduced at the base.
  • the plastic material lies against the inner walls of the recess and forms the inner part of the opening device, while the base is deformed to form the recess described to reduce the volume of the packaging.
  • the plastic material deforms itself in this way. It is preferred if the increase in volume of the packaging in the region of its opening device corresponds to the reduction in volume in the region of its recess in the base.
  • the devices for heating the top wall and / or the floor or the relevant area of the floor or the top wall are not described here. Devices known per se can be used here. But it is interesting that you can use these known heating devices, even if the packaging is filled.
