Pliers-like screw cap opener

The invention relates to a pliers-like screw cap opener from Plastic, essentially consisting of an inside with ribbed handles provided, axially cut ring, on the two of which each other facing ends are formed substantially radially extending caliper levers.

Such pincer lock openers have proven to be quite useful in the household. Thanks to the elasticity of the plastic material, the entire opener, i.e. the opener ring provided with the gripping ribs the radially molded pliers arms, made in one piece from plastic, in particular injection-molded, with the one opposite the plier levers Bogenberoich acts as a film hinge. Thanks to the elasticity of the Plastic material, the opener can also be adapted to screw caps of different diameters, but it is disadvantageous that these Adaptation to different screw cap diameters is only possible within relatively narrow limits. To therefore all practically occurring

-z-

To be able to open screw caps easily, therefore, has to be done so far several of these openers are kept ready.

The invention is based on the object of eliminating this deficiency, i.e. to design the opener of the type mentioned so that screw closures with all practically occurring different radii can be easily opened, the opener being simple in construction and easy and inexpensive to manufacture by injection molding . '■■

i The solution to this problem is according to the invention that the Clamping ring on its inside two or more concentric, axially offset pairs of clamping jaws with different Has radii. Two or more pairs of clamping jaws for closures are coaxial with one another or one above the other different radii. With each pair of clamping jaws, a certain diameter range of screw closures can be gripped. The gradation of the individual pairs of clamping jaws is such that the 'diameter ranges within which the individual [ Jaw pairs are applicable, overlap slightly. j

In a further training dor invention it is proposed that one of the caliper levers diametrically opposite, known per se Form a film hinge between the pairs of clamping jaws Bulge is provided that doubles as an opener ring for Closures with the smallest radius is formed.

According to the invention, two pairs of clamping jaws are provided concentrically to one another, axially offset from one another, namely a clamping jaw pair 3, 3 'and a somewhat larger clamping jaw pair k, h ^% . For screw closures that are too large for the smaller pair of clamping jaws 3.3 *, the pair of clamping jaws k, k 'is suitable. The pairs of clamping jaws are equipped with axial gripping ribs 5.
