CARLSCHNUERLE in FRANKFURTa. M. Safety cap for bottles.

Addendum to patent 222100 of October 17, 1908.

Patented in the German Empire on June 7, 1911. Longest duration: October 16, 1923.

In the case of the safety lock shown in patent specification 222100, the fastening means is of the insert so "arranged that it except for the enlarged point of the bottle neck at the same time it also fills the upper part of it, where it is directly after on its surface is open on the outside. Using; a non-crumbling or unbreakable fastener is an attack on the

10 'fastening points of the same possible insofar as it can be done by means of a suitable tool in can be detected and pulled out straight from the outside. Here is a Removal of the insert is still very much facilitated by the fact that one is using at the same time a wire, etc. also in a straight line from above into the flow channels and thereby still able to support a pulling out substantially. To make this impossible too make, the arrangement of the main patent is now changed so that the fastening means attached and from only in a lower widened part of the bottle neck a narrower upper part of the neck is covered. This arrangement is in itself has already been used in known safety locks. But also with You can still do this directly in a straight line from above either to the fastening means or reach the inside of the bottle through the channels. In the present invention this is now prevented by combining the above-mentioned known arrangement with the covering of the narrower neck part by the head or head edge according to the main patent. As a result of this union, the fastener comes to lie so deep that it can also be with the help of a wire or other Tool becomes impossible to get to the fastening means.

Another characteristic of the invention is seen in the new feature, that the fastening means of the insert consists in a narrow part, which in any Number either attached to the circumference of the same or pushed through the insert is and between the latter and the bottle neck wall the flow cross-section can form for the bottle contents. This new way of fastening does not allow only a further reduction of the fastening material, but is also suitable to reduce a possible attack possibility even more, furthermore the work of manufacturing of the closure, to avoid ruptures of the bottle neck and use a larger one in the absence of vertical incisions or perforations To give strength.

The figure Fig. 1 shows a safety lock half in section and half in the external view, in which the head edge α of the insert and one of

covered the neck of the bottle, preventing it from being pulled out, above the The end face of the fastener overlap like a shoulder and this from 5 cover above. The head edge of the insert with its end face shields the channels or outlet openings of the at the same time Liquid.

In Fig. 2 is the point where the

ίο Cover both parts mentioned, not above the neck of the bottle, but inside. The closure of the bottle contents can then be effected by a stopper instead of a cap e, a rubber ring f 0.

According to FIG. 3, the fastening means d of the insert consists of a closed or split ring made of cork, rubber or the like that surrounds the circumference of the insert.

According to FIGS. 4, 5 and 6, which are shown on a somewhat reduced scale, as is FIG are drawn in cross-section, it consists of narrow parts, which are either on Perimeter of the insert attached or pushed through the latter. Such Narrow parts can of course be present in any number and at the same time between itself, the insert and the bottle neck wall form a flow cross-section for the bottle contents.

The cross-section according to FIG. 3 shows, for example, an embodiment in which the 'flow channels consist of four grooves c cut into the circumference of the insert, which are delimited by the fastening means d. For the essence of the invention it is irrelevant how the flow channels are designed and arranged, whether they exist in grooves or through bores of the insert with lateral branches, etc., and how many such channels are present. These arrangements as well as the method of fastening cork rings or the like on the insert and securing it against being pulled out of the same can be selected as desired.

It is very advantageous if, as can be seen in FIG. 2, the narrowed point of the bottle neck b is clamped firmly between the head edge a and the fastening means d. Due to its elasticity, the latter then pulls the upper part of the insert firmly against the narrowed point and thereby forms a solid abutment.
