Pliers for opening a screw cap on a container.

Containers, for example jars for jam, inserted Fruits and the like, but also bottles for fruit juices, spirits and the like, are known to be very often provided with screw caps which are very difficult to open. The reason for this is due on the one hand to the underpressure that is often present in the container, on the other hand to webs between the closure and a another ring placed around the container, which, when opening the Screw cap must be torn off.

There are now a pair of pliers known with which the opening of such Screw caps should be facilitated. For this purpose, these pliers have two articulated arms which are shown in the area adjacent to the joint is semicircular in shape.

are bays, and there individual jaws for gripping a screw closure edge own. The pliers are made of metal and the individual parts are rigid.

It has now been found to be very disadvantageous that the use of individual jaws to grip the screw cap. Locally excessive stresses on the screw cap and partly via this also causes the container, so that the screw cap and possibly even the container is damaged will. The screw cap is then often no longer usable for a secure closure of the container.

The purpose of the innovation is to create a pair of pliers that no longer has the above disadvantages, is easy and safe to handle and, moreover, is simple in construction and very economical can be produced.

The pliers according to the innovation for opening a screw cap of a container is characterized in that it encompasses at least a large part of the screw cap and on this hanger that can be snuggled with handles arranged at its ends.

The bracket is expediently ribbon-like and resilient, so that it always returns to its original position when at rest. It is important that he is on the screw cap hugs. Such a bracket can be adapted to screw caps of different diameters by opening or closing

in such a way * that he does not work in individual areas attacks the screw cap, but engages around at least the largest part of the screw cap. This becomes the latter not overloaded in areas; but rather when the Forceps generated pressure of the bracket is over a larger area distributed.

The inside of the bracket is expediently designed in such a way that that sliding of the bracket attached to the screw cap is avoided. For this purpose, the inner surface can be roughened or with a non-slip covering, for example made of rubber, be provided. The simplest, most effective solution, for example, has proven to be the provision of ribs aligned parallel to the axis of the bracket has proven successful.

In order to facilitate the application of the pliers, the edge of the bracket facing away from the container is, for example, at least in places provided with radially inwardly directed lugs, with the help of which the pliers on the top of the screw cap can rest. In order to prevent slipping when the pliers are operated, the one facing the container can also be used Edge of the bracket in places or over the entire length of the bracket with an approach that engages under the screw cap be provided.

In the drawing, an embodiment of the pliers according to the innovation, described in more detail below, is shown. The pliers shown cut in half are suitable

for example to open screw caps on jam jars.

A bracket 1 has a circular cross-section and is divided at point 2. At the ends the bracket goes in Handles j5 and 4 above. The inside of the bracket is with ribs 5 aligned parallel to the axis of the bracket are provided, which, in contrast to the example shown, are preferably sawtooth-like can be designed such that the teeth open when of the screw cap are effective. The bracket 1 is kept wider than the width of the screw closures that can be revealed with these pliers.

One edge of the bracket 1 has three evenly distributed, radially inwardly projecting lugs 6 and the other Edge with a radial that extends over the entire length of the temple inwardly directed approach 7 provided »In the present example is the upper edge of the bracket in addition to the approaches β also provided with a continuous approach 7. The latter, however, has more visual than technical significance.

The pliers are expediently made of plastic, preferably "Delrin" (polymethylene oxide), and can therefore be very easily are manufactured by injection molding.

To apply the pliers, open the handles 5, 4 the bracket 1 so far that it can be opened over a Screw cap can slide. You now lead the bracket over the

Screw cap until it rests on the latter with its stops β * When the handles 3, 4 are pressed together, the bracket 1 rests firmly on the circumference of the screw cap. The screw cap can then be pivoted by pivoting the compressed
Handles can be opened. The ribs 5 ensure that the bracket does not slide on the screw cap. Announcement 7 takes effect
under the edge of the screw cap and thus prevents
slipping of the pliers when opening the screw cap,
