Bottle for aerosol.

seen G ttU (6.0?)

The innovation relates to an aerosol-containing bottle which, with the exception of the bottle neck opening, is completely closed is, and wherein a valve is arranged in the bottle neck opening.

Although Ef is known, various glass items for laboratory use to protect against breakage, e.g. as a result of a shock, by d-> ß man i, ie inside or outside with one or more plastic layers coated, however, when lining a glass article with a plastic layer, the fragility becomes fragile of this article is not diminished because of the vitreous humor even towards the outside there is still a thermal error or mechanical phenomenon Is exposed to influences, so one is only exposed to an internal one Plastic coating does not reduce the fragility of the glass article achiever k = mn. An inner plastic cover, which is supposed to reduce the fragility ^ ine ρ plaster of paris, Only then does it make sense who is dealing with a glass particle that either serves to hold hard material or which has a relatively crisp filling opening, s ^ that Thus, with a glass article designed in this way, a mechanical influence on the glass wall from the inside is possible. to For this purpose, however, the inner plastic layer must necessarily be made relatively thick in order to achieve a sufficient

To ensure damping of a mechanical shock that acts on the glass body from the inside.

■ The section of a bottle body most prone to breakage is known to be the section that is the thinnest. This is also the reason that e.g. accidentally dropping a bottle, the thick-walled bottle neck usually remains intact, but the rest of it Bottle body splintered.

Now a bottle contains a pressurized and explosive one Medium, for example, if the bottle body is accidentally broken, the bottle neck section represents the the greatest danger, as it usually does not split up completely and, due to the explosion of the ingredient, looks like a Projectile is blasted off the rest of the bottle body and one relatively large spatial danger zone around the exposition point conditional.

Although it is also known to protect glasses for laboratory use against breakage by coating them inside or outside with one or more layers of plastic, there is still the risk that the thick-walled bottle neck will be thrown away like a bullet by the overpressure. (French Patent 1,385,808 and DDR P _a tentschrift 2? 761)

The task on which the innovation is based is to create a bottle for an explosive substance, in the event of their breakage, be it by mechanical or thermal overuse, the dangers of an explosion to a large extent be reduced.

This object is achieved according to the invention in that the entire inner surface of the bottle, including the bottle neck and beyond the edge of the bottle neck opening, with,. a tough, deformable and unbreakable i Material is lined. With such a training, in which the plastic coating extends over the edge of the bottle neck oven the opening, the bottle neck is more or less mechanically anchored to the plastic layer or plastic container, so that the connection between the bottle neck and the inner plastic container is not only due to the adhesive effect or the adhesive effect is expanded, but also the plastic layer through the valve in the bottle neck or bottle neck opening - is also anchored mechanically to the bottle neck, so that in the event of a break in the rest of the bottle body due to the damping and compressing effect of the inner plastic container, the bottle neck is no longer like a projectile blasted off or thrown away. Because the Plastic coating over the edge of the bottle neck opening extends beyond, so the bottle neck is mechanically anchored to the plastic layer and is in the event of an explosion d? s Bottle body held in place by the plastic layer.

A particularly useful embodiment is that the outer surface of the bottle is also covered with a resistant, deformable and unbreakable material is.

Further advantages and details of the innovation emerge from the following description of an exemplary embodiment with reference to the drawing, the single figure of which illustrates an aerosol bottle according to the present innovation.

The bottle shown in the figure is essentially formed by a glass bottle 1 which is provided on its inner wall with a lining made of elastic, indestructible plastic. !.

A valve can be attached to this ring, the attachment and sealing of the valve being supported by the existing plastic lining 5.
