BeschreibungDescription
Die Erfindung betrifft einen im Wege der Blasformgebung aus thermoplastischem Kunststoff hergestellten Behälter für die Aufnahme von in bezug auf Entflammung und/oder Explosion sicherheitsbedürftigen fließfähigen Medien. - Bei den fließfähigen Medien kann es sich um Flüssigkeiten, um Gase oder auch um feinteilige Medien handeln. Die elektrostatische Aufladung ist bekanntlich eine Reibungsaufladung. Sie kann verhältnismäßig hohe Spannung und beachtliche Energien aufweisen, so daß eine Funkenentladung zu zündfähigen Funken führt.The invention relates to a container made of thermoplastic material by blow molding for holding flowable media that require safety in terms of ignition and/or explosion. - The flowable media can be liquids, gases or finely divided media. Electrostatic charging is known to be a frictional charge. It can have a relatively high voltage and considerable energy, so that a spark discharge leads to ignitable sparks.
Der Erfindung liegt das technische Problem zugrunde, einen Behälter des eingangs beschriebenen Aufbaus und der eingangs beschriebenen Zweckbestimmung auf einfache Weise so zu gestalten, daß eine Entflammung und/oder Explosion der sicherheitsbedürftigen fließfähigen Medien nicht mehr stattfinden kann.The invention is based on the technical problem of designing a container of the structure and intended purpose described above in a simple manner so that ignition and/or explosion of the flowable media requiring safety can no longer occur.
Zur Lösung dieses technischen Problems ist Gegenstand der Erfindung ein im Wege der Blasformgebung aus thermoplastischem
Kunststoff hergestellter Behälter für die Aufnahme von in bezug auf Entflammung und/oder Explosion
sicherheitsbedürftigen fließfähigen Medien mit den Merkmalen
25To solve this technical problem, the subject of the invention is a container made of thermoplastic material by blow molding for holding flowable media that require safety with regard to ignition and/or explosion, with the features
25
a) die Außenoberfläche des Behälters weist ein nach der Blasformgebung aufgebrachtes Netz aus sich kreuzenden, bandförmigen Sicherheitsstreifen auf,(a) the external surface of the container has a network of intersecting, band-shaped safety strips applied after blow moulding,
• · · 4· · 4
b) die Sicherheitsstreifen bestehen aus einem leitfähigen Pulver,b) the security strips consist of a conductive powder,
c) das leitfähige Pulver ist in die Oberfläche des Behälters eingesintert,c) the conductive powder is sintered into the surface of the container,
wobei der Sintervorgang so geführt ist, daß die Sicherheitsstreifen eine für die Verhinderung einer elektrostatischen Aufladung ausreichende elektrische Leitfähigkeit aufweisen.the sintering process is carried out in such a way that the security strips have sufficient electrical conductivity to prevent electrostatic charging.
Behälter aus thermoplastischem Kunststoff, die antistatisch ausgerüstet sind, sind bekannt. Nach dem Stand der Technik werden leitfähige Substanzen in den Werkstoff eingebettet, aus dem der Behälter aufgebaut ist. Das kann zu Beeinträchtigungen der Festigkeit führen, was sich insbesondere bei durch Blasformgebung hergestellten Behältern negativ auswirkt. Demgegenüber geht die Erfindung von der Erkenntnis aus, daß es zur antistatischen Ausrüstung eines 0 im Wege der Blasformgebung hergestellten Behälters aus thermoplastischem Kunststoff nicht erforderlich ist, antistatisch wirkende Substanzen in den Kunststoff einzumischen. Es ist überraschenderweise ausreichend, sich kreuzende, bandförmige Sicherheitsstreifen anzubringen, wenn diese so aufgebaut sind, wie es sich aus den Merkmalen b) und c) des Schutzanspruches 1 ergibt. Die Festigkeit des Behälters wird dadurch nicht störend beeinflußt.Containers made of thermoplastic material that are antistatic are known. According to the state of the art, conductive substances are embedded in the material from which the container is constructed. This can lead to impairments in strength, which has a negative effect, particularly in containers made by blow molding. In contrast, the invention is based on the knowledge that in order to make a container made of thermoplastic material that is made by blow molding antistatic, it is not necessary to mix antistatic substances into the plastic. It is surprisingly sufficient to attach intersecting, band-shaped security strips if they are constructed as follows from features b) and c) of claim 1. The strength of the container is not adversely affected by this.
Im einzelnen bestehen im Rahmen der Erfindung mehrere Möglichkeiten der weiteren Ausbildung und Gestaltung des erfindungsgemäßen Behälters. So handelt es sich bei dem leitfähigen Pulver nach bevorzugter Ausführungsform der Erfindung um Metallpulver, beispielsweise Kupfer- und/oder Zinkpulver. Um die Einbettung des Pulvers bzw. der Pulverteilchen zu verbessern, empfiehlt es sich, z. B. durch eine Beflammung oder eine Koronaentladung, ggf. aber auch durch eine mechanische Behandlung, die Oberflächenhaut des Behälters zumindest im Bereich der Sicherheitsstreifen aufzubrechen. Die Sicherheitsstreifen werden nach bevorzugter Ausführungsform der Erfindung mit Hilfe eines Plasmastrahls eingesintert. Das führt zu einer Struktur, die am fertigen Behälter ohne weiteres erkennbar ist.In detail, there are several possibilities within the scope of the invention for further design and construction of the container according to the invention. For example, the conductive powder according to the preferred embodiment of the invention is metal powder, for example copper and/or zinc powder. In order to improve the embedding of the powder or powder particles, it is recommended to break up the surface skin of the container at least in the area of the security strips, e.g. by flame treatment or corona discharge, but possibly also by mechanical treatment. According to the preferred embodiment of the invention, the security strips are sintered in using a plasma jet. This leads to a structure that is easily recognizable on the finished container.
Die Maschenweite des Netzes, welches aus den Sicherheitsstreifen gebildet ist, soll maximal 15 cm, vorzugsweise aber 10 cm oder weniger, ausmachen. Das gilt insbesondere, wenn es sich bei dem Kunststoff um einen solchen handelt, der sich leicht elektrostatisch auflädt, beispielsweise um Polyethylen.The mesh size of the net made from the safety strips should be a maximum of 15 cm, but preferably 10 cm or less. This is especially true if the plastic is one that is easily electrostatically charged, such as polyethylene.
Im folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung ausführlicher erläutert. Es zeigen in schematischer DarstellungThe invention is explained in more detail below using a drawing that merely shows an exemplary embodiment. It shows a schematic representation

Der in den Figuren dargestellte Behälter 1 wurde im Wege der Blasformgebung aus thermoplastischem Kunststoff geformt. Er ist für die Aufnahme von in bezug auf Entflammung und/oder Explosion sicherheitsbedürftigen fließfähigen Medien bestimmt.The container 1 shown in the figures was made from thermoplastic material by blow molding. It is intended for holding flowable media that require safety in terms of ignition and/or explosion.
Die Außenoberfläche des Behälters 1 weist ein nach der Blasformgebung aufgebrachtes Netz aus sich kreuzenden, bandförmigen Sicherheitsstreifen 2 auf. Die Sicherheitsstreifen 2 bestehen aus einem leitfähigen Pulver. Bei dem leitfähigen Pulver mag es sich um ein Metallpulver handeln. Der Sintervorgang ist so geführt, daß der Sicherheitsstreifen 2 eine für die Verhinderung der elektrostatischen Aufladung ausreichende elektrische Leitfähigkeit aufweist. Das bedeutet, daß die Sicherheitsstreifen 2 ausreichend 0 breit sind und eine ausreichende Menge an leitfähigem Pulver aufweisen. Als leitfähiges Pulver wird vorzugsweise Kupferpulver und/oder Zinkpulver verwendet. Aus Maßstabsgründen nicht erkennbar ist die Tatsache, daß die Oberflächenhaut des Behälters 1 zumindest im Bereich der Sicherheitsstreifen 2, z. B. durch eine Beflammung oder eine Koronaentladung, aufgebrochen sein kann. Das verbessert die Haftung des leitfähigen Pulvers in den Sicherheitsstreifen 2. Das leitfähige Pulver wird zweckmäßigerweise mit Hilfe eines Plasmastrahls eingesintert. DieThe outer surface of the container 1 has a network of intersecting, band-shaped security strips 2 applied after blow molding. The security strips 2 consist of a conductive powder. The conductive powder may be a metal powder. The sintering process is carried out in such a way that the security strip 2 has sufficient electrical conductivity to prevent electrostatic charging. This means that the security strips 2 are sufficiently wide and have a sufficient amount of conductive powder. Copper powder and/or zinc powder are preferably used as conductive powder. For reasons of scale, it is not possible to see the fact that the surface skin of the container 1 may have broken open at least in the area of the security strips 2, e.g. by flame or corona discharge. This improves the adhesion of the conductive powder to the security strips 2. The conductive powder is expediently sintered in using a plasma jet. The
Sicherheitsstreifen 2 müssen ausreichend breit angelegt sein.Safety strips 2 must be sufficiently wide.
Im Ausführungsbeispiel und nach bevorzugter Ausführungsform der Erfindung mag die Maschenweite des Netzes der Sicherheitsstreifen 2 maximal 15 cm, vorzugsweise jedoch 10 cm oder weniger betragen. Im Rahmen der Erfindung können die Normen für den elektrostatischen Schutz an Kunststoffoberflächen ohne weiteres eingehalten werden. Sie verlangen z. B. eine Größe der eingegrenzten Fläche von 100 cm2 . Das erlaubt Flächen von z.B. 10 cm mal 10 cm, aber auch von 5 cm mal 20 cm.In the exemplary embodiment and according to the preferred embodiment of the invention, the mesh size of the network of safety strips 2 may be a maximum of 15 cm, but preferably 10 cm or less. Within the scope of the invention, the standards for electrostatic protection on plastic surfaces can be easily complied with. For example, they require the enclosed area to be 100 cm 2 . This allows areas of 10 cm by 10 cm, for example, but also 5 cm by 20 cm.
