Description

Herstellungsverfahren Aerosoldosenböden mit gasdichten und druckfesten Sichtfenstern aus transparentem Kunststoff auszustatten, zur Inhaltskontrolle.Manufacturing process aerosol can bottoms with gas-tight and pressure-resistant To equip viewing windows made of transparent plastic, for content control.

Äerosoldbsen aus Metall haben den Nachteil, daß die Inhaltsmenge ohne äußere Hilfsmittel nicht kontrolliert werden kann. Die Inhaltsmenge läßt sich z.B. mit Feinwaagen errnitteln; diese Methode ist jedoch für den Be-Kutzer zu umständlich und setzt Kenntnis des genauen Dosengewichtes voraus um Aussagen über die Inhaltsmenge zu erhalten.Aerosol pods made of metal have the disadvantage that the amount of content without external aids cannot be controlled. The amount of content can be e.g. calculate with precision scales; however, this method is too cumbersome for the user and assumes knowledge of the exact can weight to make statements about the amount of content to obtain.

Augenblicklich die Inhaltsmenge kontrollieren zu können erhöht den Gebrauchswert der Aerosoldosen für den Benutzer erheblich, da für rechtzeitige Neubeschaffung vor restlosem Verbrauch des Inhaltes gesorgt werden kann.Being able to control the amount of content instantly increases the The utility value of the aerosol cans for the user is considerable, as they allow them to be purchased in good time can be taken care of before the complete consumption of the content.

Nach vorliegender Erfindung soll der Boden der Aerosoldose mit einer Anzahl Löcher versehen werden und eine zylindrische Verformung in Richtung Doseninnenraum aufweisen. Die durch die Löcher hindurchtretende Kunststoff-Schmelze bildet auf beiden Seiten des Aerosoldosenbodens eine Schicht. Nach dem Erkalten der Kunststoff-Schmelze ist an der Zylindermantel-Fläche eine gasdichte Verbindung durch Schrumpfung entstanden.According to the present invention, the bottom of the aerosol can with a Number of holes are provided and a cylindrical deformation towards the interior of the can exhibit. The plastic melt passing through the holes forms a layer on both sides of the bottom of the aerosol can. After the plastic melt has cooled down a gas-tight connection has been created on the cylinder jacket surface through shrinkage.

Bei Aerosoldosen, die mit diesen Boden ausgestattet sind, läßt sich beim waagerechten Halten an der Höhe des Flüs-Sigkeitsspiegels in den Sichtfenstern, augenblicklich die Inhaltsmenge feststellen.With aerosol cans that are equipped with this base, can when holding horizontally at the height of the liquid level in the viewing windows, instantly determine the amount of content.

In der Zeichnung ist eine Ausführungsform des erfindungsgemäßen Aerosoldosenbodens beispielsweise dargestellt.In the drawing is an embodiment of the aerosol can bottom according to the invention for example shown.

Es zeigen: Fig.1 Einen Längsschnitt durch eine Aerosoldose, unterer Teil, mit einem ublichen Boden(1).They show: FIG. 1 a longitudinal section through an aerosol can, lower Part, with a usual bottom (1).

Fig.2 Die Draufsicht auf einen Aerosoldosenboden mit Anordnung der Löcher(2) und (3) und der Zylindermantel-Fläche(7).Fig.2 The top view of an aerosol can bottom with the arrangement of Holes (2) and (3) and the cylinder jacket surface (7).

Fig.3 Einen Schnitt A - A, vergrößerte Darstellung, mit der Kunststoff-Schicht(8).3 a section A - A, enlarged view, with the plastic layer (8).

Der Aerosoldosenboden(1) ist mit einem zentralen Loch(2) und mit mehreren Löchern(3) versehen. Die Löcher(3) sind so angeordnet, daß zwischen äußerdem Lochkreisdurchmesser(4) und dem inneren Bördelrand(5) eine Ringfläche(6) ensteht.The aerosol can bottom (1) has a central hole (2) and several Holes (3) provided. The holes (3) are arranged so that between the outer pitch circle diameter (4) and the inner beaded edge (5) has an annular surface (6).

Dicht an dem äußeren Lochkreisdurchmesser(4) ist der Aerosoldosenboden zylindrisch in Richtung Doseninnenraum verformt. Die entsiajdene Zylindermantel-Fläche(7) ist maßgebend für die Güte der Dichtigkeit Aerosoldosenboden -Kunststoffschicht. Die durch das zentrale Loch eine spritzte Kunststoff-Schmelze umfließt die beiden Seiten des Aerosoldosenbodens. Nach dem Erkalten der Kunststoff-Schmelze ist auf beiden Seiten eine durch die Löcher(2) und (3) verbundene Kunststoffschicht(8) und an der Zylindermantel-Fläche(7) eine gasdichte Verbindung durch Schrumpfung entstanden.The bottom of the aerosol can is close to the outer hole circle diameter (4) cylindrically deformed towards the interior of the can. The desiccated cylinder jacket surface (7) is decisive for the tightness of the aerosol can bottom plastic layer. The plastic melt injected through the central hole flows around them Sides of the aerosol can bottom. After the plastic melt has cooled down, it is on a plastic layer (8) and connected through the holes (2) and (3) on both sides A gas-tight connection was created by shrinkage on the cylinder jacket surface (7).
