Opener for crown cork closures.

The invention relates to one for the aforementioned Crown cap closures specific opener that of one Handle part is widened like a spoon, and within this widening a transverse to the longitudinal axis of the opener has a lying, long ring eyelet breakthrough for receiving part of the circumference of the crown cork closure, this opening being limited on the side facing the handle by a flat, tongue-like projection, the front edge of which is facing the opening as the flood-lift edge engages under the circumferential edge of the crown cork closures, while this flood-lift edge Opposite Durohbruch limit edge is supported as a supporting edge on the ceiling of the crown cork closure.

In the case of crown cap openers, the one at the beginning mentioned genus corresponds to the distance between the lifting edge engaging under the crown cap closure at its corrugated peripheral edge and the one on the supporting edge supporting the crown cork cover about the half the diameter of the crown cap itself, whereby such an opener inevitably about when opening the crown cap closure with its supporting edge must support in the middle of the lid. This inevitably has the consequence that the closure cover is approximately in its central area is bent upwards on the one hand and is so strongly deformed that it can be reused to temporarily re-close the bottle is impossible. On the other hand, the corrugation of this crown cap closure is widened considerably. Both Phenomena therefore lead to the fact that a cork is in any case unusable for reuse.

In terms of construction, crown cork closure openers of the type described above are designed so that the Cloak of the crown cap circumferentially reaching under The lifting edge and the supporting edge, which is supported by the top of the crown cap, are at the same height, what

has the consequence that the inserting conditions of the opener are extremely unfavorable at the closure. You have to - in order to open the lock - the opener almost in bring a vertical plane to the closure. Yes, sometimes this position is so unfavorable that between the handle of the opener and the one to be opened Bottle hardly has enough space for the hand to grip the opener.

And finally, it is with the previously known openers, which are designed according to the pre-designed features are, inevitably, that when opening at least the upper edge of the bottle, which through such a Crown cork closure closed, highly endangered is because it happens again and again - especially when it is opened quickly or handled inappropriately, that the edge of the bottle is damaged, so that broken glass get into the bottle, i.e. into the liquid, which is undesirable and dangerous.

Recognizing all these disadvantages, the present invention has the task of being effective here To remedy this, first of all, that the support edge

909887/0102

of the opener in one the diameter of the crown cap closure in the area of its cork top the distance below the lift-out edge of the opener is arranged in front of and offset in height to this.

By putting the invention into practice is now, due to the features of the invention, an opener for crown cap closures created, its supporting edge supported on the ceiling of the closure - due to the distance ratio between Lifting and supporting edge - not more in the area of the jacket the ceiling, but almost in the outermost edge area of the ceiling, i.e. at one point of the crown cork, where this is supported below by the edge of the bottle.

If you now open a crown cork closure with the new crown cap opener, then it will it through the new spacing ratios of lifting and Support edge achieved that neither the crown cork is deformed folding upwards, nor the circumferential swell in the is widened so far in a highly disadvantageous manner. The crown cork closure can thus for the first time - and in it a very special feature of the invention is seen -

for a temporary reclosure of the bottle can be used again, because when opening with the new opener there is no previously unavoidable FaIt or Kniolc deformation by the opener is more subject.

It is also crucial for the invention that this new opener only without any additional effort offers the advantages already described and in the following by a more skilful and more appropriate embossing yet to be described.

In addition to the option already mentioned, a crown cap closure, which by means of the new opener has been removed from the bottle, use it again To be able to do so, the invention not only fulfills one long-cherished wish in practice, but another The advantage is also seen in the handling when opening.

In the case of the new opener, the support edge, which is supported on the cover of the crown cork closure, is opposite to the raised edge which extends under the circumference of the jacket of the crown cork closure is arranged offset in height, the ine et ζ ratios of the opener on the closure are much more favorable because

- 5 -90 9887/0102

you can now almost in a horizontal plane so in can start a technically favorable direction, whereby in the area between the handle of the Opener and the bottle itself a not inconsiderable amount of free space is gained.

And finally, with this new opener it is also advantageous that the circumferential edge of the Crown cork Verachlusses undercutting Auehebekante about a third of the circumference of the cork has a corresponding intrinsic length. As a result, the peripheral edge of the crown cap becomes substantial on one side greater length than before, so that the risk of expansion of the jacket waves of the crown cork is also significantly reduced as a result as well as the risk of the opener slipping off from the closure cap.

now also - as the invention also suggests - ti · lifting edge and supporting edge of the opener have approximately the same length, the crown cap closure will not only overlap over a considerable length but also practically over the same length.

- 6 -909887/0102

The extremely favorable conditions on the new opener ultimately affect the handling of the opener also that there is no danger of closing the upper edge of the pan in any way when opening injure, as has been the norm up to now.

A practical implementation of the invention can now find its expression in the fact that the support edge of the opener has a leg running in the horizontal plane, at least in the region of this support edge at obtuse angles Breakthrough edge web showing cross-hole is, while the second leg part of this edge web as a collar, the rear peripheral edge part of the crown cork Versohlusses overlaps, wherein the support edge at least over parts of its length as parallel to the lifting edge extending support surface is formed.

As a result of this design, in particular of the supporting edge area, crown cork openers are previously known Art previously unachieved favorable support conditions in the area of the crown cap closure cover on the one hand and the rear part of the circumference reached on the other hand.

- 7 -909887/0102

It has now been found that the conditions are particularly favorable when the distance between the lifting and supporting edge is about 9/10 of the Diameter of the crown cap is. It is precisely with such a dimensioned spacing that it is achieved that the top of the crown cap is still loaded at its outermost point by the support edge of the opener, whereby the kinking phenomena that have occurred up to now in the middle of the ceiling are eliminated.

In summary, it remains to be stated that the invention has succeeded for the first time in achieving an astonishing optimum effect without any additional expenditure, This makes it possible for the first time to lift crown caps from a bottle with practically no deformation and to be able to use them again.

The invention thus solves a much desired problem in practice, thereby reducing its utility value Openers of the previously known type is decisively improved and, for this reason, also provides a considerable forteohtttt with an amazing effect on the hand.

gene widening 10a is a long round Breakthrough 11, which is transverse to the longitudinal axis of the opener lies. This breakthrough 11 is on the handle side delimits a tongue-like projection 12b. This tongue-like projection 12 is located opposite an edge web delimiting the opening 11 on the opposite side 13. The tongue projection 12 for End edge 12a delimiting the opening side engages under the opening division of such an opener the circumferentially corrugated jacket 14a of a crown cap closure 14, while that of the lifting edge 12a opposite support edge 13a of the boundary edge is supported on the upper side on the cover 14b of the crown cap closure.

In the present embodiment of a crown cap closure opener, the distance is now dimensioned from the lifting edge 12a to the supporting edge 13a so that that this is the diameter of the crown cap closure in the area of the ceiling 14b is slightly below, e.g. 9/10 of the diameter. Besides, the Support edge 13a is arranged offset in height with respect to the lifting edge 12a. The support edge 13a is parallel
