Method for centering bottles and bottle for implementation of the procedure

The invention relates to a method for centering bottles and also relates to the application of this method for applying colors to the side surfaces of a glass bottle, which can be etched or matted with acid or not. The invention also relates to bottles which can be used for carrying out the method according to the invention are.

It is known that the attachment of precious metals such as e.g. gold or platinum existing letters or decorations causes a matt appearance on etched or non-etched glass, which is perceived as unpleasant by the eye. As often liquid quality products in bottles or flacons are sold from etched or frosted glass with a gold inscription, this disadvantage has to be remedied tried to apply an uncolored background made of transparent enamel to the glass. ¥ ¥ enn however this

Layer is applied in the form of a continuous ground, the result is a little aesthetic appearance, because one of the shiny ground under and around the gilded ornament.

For the production of such high quality products, it is therefore necessary to apply the enamel background only under the gold-plated imprint. As a result, the position of the bottle or bottle must be marked with great accuracy, both in the longitudinal direction, ie along the axis, and radially with respect to this axis, so that the gold-plated letters or decorations are applied exactly to the corresponding background .

This marking is extremely difficult, and attempts have already been made to meet these requirements to use two impressions below the bottle recess as reference points with respect to the axis of the bottle or bottle are arranged and correspond to centering projections that protrude on the surface of the trough shape at the bottom of the bottle. These necessarily small protrusions are fragile and are heated to a considerable extent during bottle manufacture, since they penetrate a sizeable pool of hot glass, which also provides considerable lubrication to these protrusions requires. The lubricant, which decomposes in the heat, creates traces of carbon which are thicker at the edge of the protrusion produce. The pressing of the projections into the bottom of the bottle does not exactly correspond to the dimensions of the projection, what the occurrence of considerable play when marking the position of the bottle.

For such a marking it is therefore necessary to carry out tests to determine the play between the impressions at the bottom of the

- 3 - 609834/097 6

To assess the bottle and the protrusions on the tailstock of the centering device on which the bottle to be decorated is seated. Even In practice it has been found that this game is very difficult to make out, since the resulting proportion of waste reached a value of 40%.

The aim of the invention is to eliminate these disadvantages and to provide a method for precise and invariable marking to indicate the position of a bottle.

In the method according to the invention, the centering is with carried out a tailstock, the profile of the bottle bottom with a hollow as a circular centering indentation with a large diameter, with greater depth than usual and with a sufficiently large and no lubrication corresponds to the tapering required during the molding process of the bottle, furthermore a single indentation for the angular marking two parallel surfaces arranged essentially perpendicular to the circumference of the circular indentation in the trough are provided.

The indentation for the angle marking can be on the circumference of the circular Trough or be arranged along a radius of the trough.

Independently of this, the trough can be arranged raised or hollowed out at the bottom of the bottle.

The invention also relates to an application of the method for marking the position of a glass bottle, which may or may not be matted or etched with acid, when applying Letters or decorations, especially if a gold or platinum-based paint is used for application.

The invention further relates to a bottle which can be used for carrying out such methods and which is characterized

- 4 - '609834/0976

by a bottle bottom with a trough, which is a circular centering indentation with a large diameter, with greater depth than normally usual and with a sufficiently large taper, and further in the trough with a single Countersink to mark the angle with two parallel »essentially is provided perpendicular to the circumference of the circular indentation surfaces.

The essential feature of the invention can be seen in the fact that the trough and the device for angular marking at the bottom of the bottle form a single, solid block which is not contaminated during operation and is not fragile and which, moreover, has no play against the corresponding elements of the tailstock the centering device.

Advantageously, the indentation to the ¥ angle marking on the bottom of the bottle during the molding process of the bottle is detachable with a performed at the bottom of the mold part, so that this part can be replaced in the event of wear, which increases reproducibility the dimensions of the indentation guaranteed during operation.

The drawings show in:

1 shows a section of a bottle according to the invention on a centering tailstock; and in

Fig. 2 is a view of the bottom of the bottle according to the invention from below.

As can be seen from the drawings, the bottom of a bottle 1 essentially has a circular trough 2 with a large diameter and of considerable depth and with a depression 3 on the circumference, with two effective parallel, substantially perpendicular

_ 5 - 609834/0976

to the circumference of the trough extending surfaces is provided. As can be clearly seen from FIG. 1, a corresponding one is inserted into this trough profiled part 4 of a centering tailstock 5, while a stop 6 is in engagement with the recess 3. the the two parallel surfaces 6a and 6b of the stop 6 lie against the corresponding surfaces 3a and 3b of the depression 3 so that a complete angular centering of the bottom of the bottle is ensured on the centering tailstock.

Such a centering is particularly suitable for decorating or patterning with the help of a paint on the basis of precious metals from glass bottles that have previously been etched with acid may or may not be, since you can precisely mark the position of all places on which an 'enamel base is applied so that the decorative motifs can then be applied in exactly the same places «

Such a centering can also be used to apply colors from enamel ceramics, since the two colors are set in a precise manner in their position to each other.
