Device for loosening peripheral grooves provided screw caps of bottles

^ One knows a device for solving with

screw caps provided with peripheral grooves of bottles with a conical narrowing insertion hole and one on its conical surface inwardly protruding protrusion extending in the direction of the generatrix Handle.

The handle is opened with its insertion hole and the sharp-edged projections located in it the screw cap to be loosened is attached to a bottle and pressed so strongly that s ± ch preferably metallic protrusions in the peripheral grooves in the screw cap more or less

Cut deeply so that the screw cap is held in place in this way by the handle and becomes rotatable. Even if only one in the conical insertion hole of said handle. only one sharp-edged projection is arranged and the screw cap on the opposite of this projection Side rests against the smooth-walled conical surface of the insertion hole, is therefore not yet safe A guarantee that the attached handle securely grasp the screw cap and turn it with it can. In this situation, the screw cap is only used at two opposite points

- touched so that the screw cap in the plug-in

loch the handle can wiggle and make undesired evasive movements · This loose The seat of the screw cap in the insertion hole of the handle can therefore be found in the case of the described Avoid construction practically only by making a three-point contact using three sharp-edged projections in the form of inserted metal knives is brought about, which, however, among other things The one major disadvantage is that three metal inserts have to be used, which complicate the production of the handle and increase its cost price.

The invention is based on the object of modifying the device described above in such a way that and to simplify that the disadvantages mentioned are avoided and the essential advantages of easier attachment and easier handling be achieved·

This object is achieved according to the invention in a device of the type mentioned at the beginning in that the conical insertion hole has a bulge opposite a single projection *

The bulge is expediently separated from the rest of the space of the insertion hole by two sharp edges

It is also advantageous if the insertion hole is closed on the top by an end wall.

In the following, an embodiment of the invention is explained and described in more detail with reference to the drawing. It show t

with inserted screw cap »

The handle 1 has a conically formed insertion hole 2, in the conical lateral surface 5 ⁱⁿ the direction of the generatrix extending sharp-edged metallic projection 6 is inserted.

The insertion hole 2 has a protrusion 6 opposite this bulge 8, the ssweckmässig from the rest of the space of the insertion hole »is delimited by two sharp edges 9 ·

This additional free space created by the bulge 8 facilitates the plugging of the handle 1 onto the screw cap 3 of the FIp.-sche k as well as the entire handling significantly «When using the handle 1 is placed in an approximately horizontal position on the screw cap 3, so that this is touched on three points of a plane "which is indicated by the straight line 10 in Figure 2 · then, on one side of the mounted grip" tucks a small pressure in the direction of arrow 13 exerted downward, so that the only metallic "" insert 6 penetrates into a groove and presses into the material of the screw cap · The three points of contact

between the handle 1 and screw-inJLuis 5 are then in a plane that in Figure 2 through the straight line 11 is indicated * "

The insertion path 14 forms together with the straight lines 10 and 11 roughly a right-angled triangle, the hypotenuse of which is formed by the straight line 10 and the longer cathetus by the straight line 11. The knife-like projection 6 thus penetrates the screw cap by the same amount as the Straight line 11 is shorter than straight line 10

After placing the handle 1 on one side and pushing it downwards, this can be easily done with the help of of the outer ribs 7 turn "

The bulge 8 from the rest of the space of the insertion hole 2 from £ bordering scheu fen edges 9 press similar to the knife 6, but to a lesser extent, in the outer groove of the screw, so that a firm three-point clasp is achieved in this way through which the screw cap remains clamped and any slipping or other wobbling is excluded «

The device described B is thus characterized by a very simple, material-saving design and absolutely functionally reliable handling. as well as a very long service life from
