Description

Beschreibungdescription

Blisterbord Die Erfindung bezieht sich auf ein Blisterbord mit einer aus thermoplastischer Kunststoffolie bestehenden Mulde, die mit ihrem Rand an einem tragenden Rahmen befestigt ist. Blister board The invention relates to a blister board with a made of thermoplastic plastic film trough, which with its edge on a load-bearing frame is attached.

Solche bekannten Blisterbords haben sich zur Verpackung von Massenartikeln allgemein durchgesetzt. Es hat sich nun gezeigt, daß aufgrund der Eigenschaft von thermoplastischem Kunststoff elektrischen Strom extrem schlecht zu leiten, Nachteile für in solche Blisterbords verpackte Artikel auftreten können. Solche Nachteile ergeben sich dadurch, daß die Mulde aus thermoplastischem Kunststoff bei hoher statischer Ladungsdichte sich plötzlich zum verpackten Artikel hin entladt. Handelt es sich bei dem verpackten Artikel z. B. um einen solchen, der elektronische Schaltungen aufweist, wie z. B.Such known blister boards have been used for the packaging of mass-produced articles generally enforced. It has now been shown that due to the property of Thermoplastic plastic conducts electricity extremely poorly, disadvantages for articles packed in such blister boards. Such disadvantages result from the fact that the trough is made of thermoplastic at high static Charge density suddenly discharges towards the packaged article. Is it in the packaged article e.g. B. to one of the electronic circuits has such. B.

MOS-Bausteine, so kann unter Umständen durch eine solche Entladung der Artikel zerstört werden. Aufgabe der vorliegenden Erfindung ist es deshalb, gattungsgemäße Blisterbords so zu verbessern, daß eine Gefährdung der verpackten Artikel durch plötzliche Entladung statischer Elektrizität ausgeschlossen ist.MOS devices can, under certain circumstances, be caused by such a discharge the item will be destroyed. Object of the present invention it is therefore to improve generic blister boards so that a hazard of the packaged items excluded from sudden static electricity discharge is.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst" daß die Kunststoffolie antistatische Leitfähigkeit aufweist. Durch die erfindungsgemäße Verwendung einer antistatischen Folie wird erreicht, daß elektrische Ladung, die auf der thermoplastischen Kunststoffolie entsteht, sofort zum Rahmen des Blisterbords hin abgeleitet wird, so daß erstens keine hohen Ladungsdichten mehr auftreten können und zweitens eine plötzliche Entladung ausgeschlossen ist. Erfindungsgemäß ausgebildete Blisterbords sind demzufolge auch für die Verpackung hochempfindlicher elektronischer Geräte geeignet.According to the invention, this object is achieved in that the plastic film Has antistatic conductivity. By using a Antistatic film is achieved that electrical charge is applied to the thermoplastic Plastic film is created, is immediately diverted to the frame of the blister board, so that firstly no more high charge densities can occur and secondly one sudden discharge is impossible. Blister boards designed according to the invention are therefore also used for packaging highly sensitive electronic devices suitable.

Aus der DE-AS 25 42 650 ist ein Schichtstoff mit einer Kernschicht aus Kunststoff und einem Oberflächenüberzug in dem die elektrische Leitfähigkeit beeinflussende Partikel gleichmäßig verteilt sind, bekannt. Ein Hinweis auf die Verwendung eines solchen Schichtstoffes zur Herstellung eines Blisterbords findet sich in dieser Druckschrift jedoch nicht.DE-AS 25 42 650 discloses a laminate with a core layer made of plastic and a surface coating in which the electrical conductivity influencing particles are evenly distributed, known. A note on the Use of such a laminate for the production of a blister board is found however not in this publication.

Aus der DE-OS 30 43 539 ist ein elektrisch leitfähiger Schichtstoff bekannt, der eine erste Schicht mit im wesentlichen räumlich konstanter transversaler Leitfähigkeit aufweist und eine zweite Schicht, die als volumenleitfähige Substratschicht ausgebildet ist.From DE-OS 30 43 539 an electrically conductive laminate is known to have a first layer with essentially spatially constant transverse Has conductivity and a second layer, which acts as a volume conductive substrate layer is trained.

Der aus dieser Druckschriftschrift bekanntgewordene leitfähige Schichtstoff wåre für die Verwendung zur Her- stellung eins Blisterbords nicht geeignet, da durch den hohen Verformungsgrad, dem die als Ausgangsmaterial verwendete thermoplastische Folie bei der Bildung der Mulde unterworfen ist, ein über die gesamte Oberfläche konstanter Oberflächenwiderstand nicht erreichbar wäre.The conductive laminate known from this publication would be for use in making position of a blister board not suitable because of the high degree of deformation that was used as the starting material thermoplastic film is subjected to the formation of the trough, one over the entire Surface constant surface resistance would not be achievable.

Eine vorteilhafte Weiterbildung erfährt ein erfindungsgemäßes Blisterbord dadurch, daß die antistatische Leitfähigkeit durch Einlagerung von Kohlenstoffpartikeln, insbesondere Ruß, in einem thermoplastischen Kunststoff hervorgerufen ist. Dabei ist es vorteilhaft, eine solche Partikelmenge zu verwenden, daß der Oberflächenwiderstand der antistatischen Schicht nicht größer als 10 Ohm wird. Die elekrische Leitfähigkeit läßt sich jedoch über diesen Wert hinaus erhöhen, indem elektrische Oberflächenwiderstände bis her-3 unter zu 103 Ohm und weniger durch entsprechende Einlagerung von Kunststoffpartikeln eingestellt werden.A blister board according to the invention experiences an advantageous further development in that the antistatic conductivity is achieved by the inclusion of carbon particles, in particular soot, is caused in a thermoplastic material. Included it is advantageous to use such an amount of particles that the surface resistance the antistatic layer does not exceed 10 ohms. The electrical conductivity however, it can be increased beyond this value by adding electrical surface resistances up to -3 under 103 ohms and less due to the corresponding inclusion of plastic particles can be set.

Bei einer bevorzugten Ausführungsform eines erfindungsgemäßen Blisterbord ist die Kunststoffolie eine an sich bekannte Zweischichtfolie, deren eine Schicht, bevorzugt die dickere antistatische Leitfähigkeit aufweist. Hierdurch oder alternativ durch die Wahl eines unterschiedlichen Materials kann die Festigkeit der antistatischen Schicht höher sein als die der zweiten Schicht.In a preferred embodiment of a blister board according to the invention the plastic film is a known two-layer film, one layer of which preferably has the thicker antistatic conductivity. Through this or alternatively by choosing a different material can increase the strength of the antistatic Layer higher than that of the second layer.

Vorzugsweise ist die zweite Schicht als Haftschicht ausgebildet und liegt demnach am tragenden Rahmen des Blisterbords an.The second layer is preferably designed as an adhesive layer and is therefore on the supporting frame of the blister board.

Sowohl die antistatische Schicht als auch die Haftschicht sollen vorzugsweise als Polyethylen bestehen.Both the antistatic layer and the adhesive layer are preferred exist as polyethylene.

Ein Ausführungsbeispiel eines erfindungsgemäßen Blisterbords ist in der beigefügten Zeichnung dargestellt.An embodiment of a blister board according to the invention is shown in FIG shown in the accompanying drawing.

Die Zeichnung zeigt einen Querschnitt durch ein Blisterbord vergrößert. Das Blisterbord besteht aus einem tragenden Rahmen 1, an dem mit ihrem Rand eine aus thermoplastischem Kunststoff bestehenden Mulde befestigt ist, wobei die Befestigung durch Verschweißung erfolgt. Die Mulde des Blisterbords besteht aus einer thermoplastischen Zweischichtfolie mit einer Haftschicht 2 und einer antistatischen Schicht 3. Die Haftschicht 2 liegt am tragenden Rahmen 1 an, während die antistatische Schicht 3 außen liegt. Die Haftschicht 2 und die antistatische Schicht 3 sind unlösbar miteinander verbunden. Wie aus der Zeichnung zu ersehen, ist die antistatische Schicht die dickere Schicht, wobei vorzugsweise die Dicke der antistatischen Schicht 3 etwa das zehnfache der Dicke der Haftschicht 2 betragen soll. Beide Schichten bestehen aus Polyethylen, wobei für die Haftschicht 2 ein Polyethylen mit niedrigerem Schmelzpunkt verwendet ist als bei der antistatischen Schicht. Ein Vergleich des Oberflächenwiderstands einer nach der in der Fig. dargestellten Art ausgeführten Mulde, bei der die anti statische Schicht aus Polyethylen mit Rußfüllung eine Dicke von 0,41 mm, die Haftschicht eine Dicke von 0,04 mm aufwies mit einer normalen nur aus Polyethylenfolie von 0,45 mm Stärke bestehenden Mulde und mit Wellpappe ergab folgende Werte in Ohm: Normale Polyethylenfolie 10 Antistatisch ausgerüstete Poyethylenfolie 104 Wellpappe 109.The drawing shows an enlarged cross section through a blister board. The blister board consists of a supporting frame 1, on which one with its edge made of thermoplastic plastic trough is attached, the attachment takes place by welding. The cavity of the blister board consists of a thermoplastic Two-layer film with an adhesive layer 2 and an antistatic layer 3. The Adhesive layer 2 rests on the supporting frame 1, while the antistatic layer 3 is outside. The adhesive layer 2 and the antistatic layer 3 are inseparable from one another tied together. As you can see from the drawing, the antistatic layer is the thicker one Layer, preferably the thickness of the antistatic layer 3 about ten times the thickness of the adhesive layer 2 should be. Both layers are made of polyethylene, a polyethylene having a lower melting point is used for the adhesive layer 2 than the antistatic layer. A comparison of the surface resistance a trough executed in the manner shown in the figure, in which the anti static layer of polyethylene with carbon black filling a thickness of 0.41 mm, the adhesive layer 0.04 mm thick with a normal only polyethylene film of 0.45 mm thickness and with corrugated cardboard resulted in the following values in ohms: Normal Polyethylene film 10 Antistatic polythene film 104 Corrugated cardboard 109.
