Bottle-like container.

You innovation relates to a bottle-like container for pressurized contents, in particular Liquids containing carbonic acid, with a convex outwardly curved base, which formed at least three, in a common, im Outwardly facing plane ending essentially normal to the longitudinal axis of the bottle: has projections which form part of the container wall and represent the corners of a polygon.

Such a container is particularly well suited for pressurized filling material because it does is easy and cheap to produce, but nevertheless absorbs the internal pressure safely and always a safe one

Stand guaranteed.

This safe stand of the container is achieved by itself The projections are turned towards the outside, but which only have a relatively small contact area between the container and its support. Pa when closing the container, a relatively strong vertical pressure, especially when applying crown corks is applied to the bottle-like container, it is desirable to reduce the contact area between the Enlarge the container and its base so that this pressure is safe and without damaging the bottle can be included.

To solve this problem, it is proposed that the convex outwardly curved floor tangent to the plane in which the junctions end »

This feature enables considerably higher pressures to be effective in the direction of the longitudinal axis of the bottle, because the curvature of the convex arched outward Container bottom has a much larger radius than the lateral projections and thus without Danger for the bottle if high pressures occur in the bottle lengthwise cylinder slightly indented and thus can become a large edition.

On the basis of the following description of an exemplary embodiment of the innovation shown in the drawing this is explained in more detail.

The figure shows an axial section through one provided with four projections on the bottom, according to the innovation trained plastic bottle.

The beverage bottle, designated as a whole by 10, has a tapered neck 12 at its upper end provided, which is suitable for the application of a closure means, in particular one Crown cap is formed. At the lower end of the cylindrical body of the bottle this goes into a Convex outwardly curved base 16, which is subjected to tensile stress in the case of internal overpressure in the bottle 10. In the cylindrical bottle body 14 can be arranged in the circumferential direction of grooves 18.

The curved bottom 15 is downwardly and radially η outwardly inverted, nose-like projections 20 are provided, which are approximately evenly over the circumference the bottle 10 are distributed. The projections 20 end in a common "plane 23" which is the convex Touched the bottom of the bottle at 21. The lower ends 22 of the projections 20 and the lowest point 21 of the convex Bottom 16 of the bottle form the points of contact of the bottle 10 and lie, in a common, approximately normal to Fleischenlängaach3e 24 running level.

To give the bottle 10 a secure stand, at least three such projections θ 20 are required, which included a triangular area as a stand area. When using two-part, preferably in the Flaf & chenlängsaohse 24 split blow molds for However, to manufacture the bottle 10, it is recommended that four of these projections be spaced apart from each other to be provided, two of them in the parting plane of the

Form are arranged. With this arrangement, the mold separates after blowing the bottle not affected.

If the bottle, for example when printing Crown caps in "the direction of their longitudinal axis through a when subjected to strong pressure, the curved base 16 can deform slightly, so that at 21 within the polygon formed by the projections 20 a broadly ridiculous edition results. !Included J can also the projections 20 by a slight Deformation of the tab bottom 16 change their position to such an extent that the area is now somewhat flattened 21 and the lower oars 22 of the protrusions 20 continue to remain in a common plane.
