Description

Eine sich durch Wasser selbst öffnende Kunstoff-Folienverpackung. A plastic film packaging that opens itself through water .

Die .Bedeutung der Kunststoff-Folienverpackung ist sehr groß. Yiele Produkte lassen sich in solche Abpackung scnnell, rationell, nygienisch und haltbar verpacken.The importance of plastic film packaging is very great. Yiele products can be packed quickly, efficiently, hygienically and durably in such packaging.

Unter den zahlreichen Kunststoff-Folien werden sowohl wasserunlösliche Folien z.B. aus Polyäthylen, Polypropylen, Polyamid, Polyterephthalsäureester, Polyvinylchlorid, Polyvinyliden, als auch wasserlösliche Folien z.B. Polyvinylalkohol, Polyoxyäthylen, Carboxymethylcellulose verwendet. Um der Kunststoff-Verpackung besondere spezifischen Eigenschaften zu geben kann sie auch aus mehrere verschiedene miteinander verbundene Folien, so genannte Verbundfolien hergestellt werden.Among the numerous plastic films are both water-insoluble Films e.g. made of polyethylene, polypropylene, polyamide, polyterephthalic acid ester, Polyvinyl chloride, polyvinylidene, as well as water-soluble films e.g. polyvinyl alcohol, Polyoxyethylene, carboxymethyl cellulose used. In order to give the plastic packaging special specific properties They are also made from several different interconnected foils, so-called composite foils.

Die wasserlöslichen Verpackungen werden meist für Waschmittel, Badezusätze, Seifen und Reinigungsmittel verwandt und haben den Vorteil, daß man sie bei Gebrauch nicht zu öffnen braucht, sondern das Mittel samt der Verpackung zum Wasser geben kann. Diese Verpackung eignet sich als Dosierpackung auch für viele andere Substanzen, die in wässerige Lösung zur Anwendung kommen, z.B. Trockenbleichmittel, Kosmetika, landwirtschaftliche Chemikalien, Insektizide, Fungizide u.a. Für die Lagerung dieser Abpackung entsteht keine unmittelbare Gefahr durch die Luftfeuchtigkeit, da es eine Vielzahl von verschiedenen Typen gibt, z.B. an die Polyvinylalkoholfolien dadurch, daß sie sich in ihren Verseifungs-, Polymerisationsgrad, Weichmachergehalt unterscheiden und eine geeignete Folie durch Versuchen wählen kann.The water-soluble packaging is mostly used for detergents, bath additives, Soaps and detergents are related and have the advantage that you do not need to open them when you use them, but rather the means and the packaging for Can give water. This packaging is also suitable as a dosage pack for many other substances that are used in aqueous solution, e.g. Dry bleaching agents, cosmetics, agricultural chemicals, insecticides, fungicides, etc. Humidity hazard as there are a variety of different There are types, e.g. to the polyvinyl alcohol foils by the fact that they are in their Be able to differentiate between saponification, degree of polymerization and plasticizer content and to choose a suitable film through experiments.

iSs wurde nun gefunden, daß man die Gefahr, die eine Verpackung bestehend aus einer wasserlöslichen Folie der Luftfeuchtigkeit ausgesetzt ist weitgehenät vermeiden oder gänzlich verhindern kann, wenn man eine Verpackung verwendet, die aus einer durch kaschieren hergestellte Verbundfolie aus einer wasserlöslichen und einer wasserunlösliche Folie besteht, wobei die wasserlösliche Folie nach innen, die wasserunlösliche Folie zur Abschirrmung gegen die Luftfeuchtigkeit nach außen zu liegen kommt.
Beiliegende Zeichnung gibt ein Schnitt durch eine Verpackung dieser Art .It has now been found that the risk that a packaging consisting of a water-soluble film is exposed to atmospheric humidity can largely be avoided or completely prevented if a packaging is used which consists of a composite film made of a water-soluble and a water-insoluble film , with the water-soluble film on the inside and the water-insoluble film on the outside to shield it from the air humidity.
The accompanying drawing shows a section through this type of packaging.

Die aufeinander leigenden wasserlöslichen Folien können miteinander verklebt oder auch verschweißt werden ( A }. Berührt man diese Stelle mit Wasser, so würde die wasserlösliche Folie erweichen und sich an dieser Stelle öffnen. Wenn erwünscht, kann nur ein Teil der Verpackung auf diese Weise verschlossen werden.The water-soluble films lying on top of one another can be used with one another glued or welded (A}. If this point is touched with water, the water-soluble film would soften and adhere to it Open position. If desired, only part of the packaging can be closed in this way.

Durch entsprechende Einstellung und Wahl des Schweißgerätes können auch die beiden wasserunlöslichen Folien über den wasserlöslichen Folien hinweg verschweißt werden, diese Stellen bleiben gegenüber Wasser unverändert ( B ). Würde man z.B. eine Verbundfolie aus Polyvinylchlorid und Polyvinylalkohol wählen, so kann man bereits durch Verwendung eines Hochfrequenzschweißgerätes ( dadurch, daß dabei lediglich das Polyvinylchlorid erweichen würde ) eine Schweißnat der Art B leicht erziehslen.By setting and selecting the welding machine accordingly, you can also the two water-insoluble foils are welded over the water-soluble foils; these areas remain unchanged in relation to water (B). For example, if you were to choose a composite film made of polyvinyl chloride and polyvinyl alcohol, you can use a high-frequency welding device (in that only the polyvinyl chloride would soften in the process) a type B weld puddle is easy to develop.

Anspruchclaim Sich durch Wasser leibst öffnende Verpackungsart dadurch gekennzeichnet, daß sie aus einem Verbundmaterial, bestehend aus einer wasserlöslichen und einer wasserunlöslichen Folie, hergestellt wurde, wobei die wasserlösliche Folie nach innen, die wasserunlösliche Folie nach außen zu liegen kommt. An der vorgesehenen Stelle, die sich durch Wasser Öffnen soll, müßigen die aufeinanderliegende wasserlösliche Folien verbunden werden, der restliche Rand muß durch eine Schweißnat so verschlossen werden, daß sich die außenliegenden wasserunlöslichen Folien verbinden.Type of packaging that can easily be opened by water, characterized by that it was made of a composite material consisting of a water-soluble and a water-insoluble film, the water-soluble Foil on the inside, the water-insoluble foil on the outside. At the intended point that should be opened by water, the water-soluble foils lying on top of one another must be connected, the rest of the edge must be sealed with a weld seam so that the water-insoluble foils on the outside join.
