Screw cap pliers

* 27A371Q

The invention relates to a screw cap pliers according to the preamble of claim 1.

Known screw cap pliers of the type mentioned above allow the screw cap pliers to grip well on the screw cap, but it has been shown that difficulties sometimes arise when loosening the screw cap, because the vacuum present in the glass means that the screw cap can only move with the application of very great forces is.

The present invention is based on the object of providing screw cap pliers of the type mentioned at the beginning to provide the same in the presence of a vacuum and thereby more difficult opening of the screw cap also permitted with large lid sizes.

This object is achieved according to the invention by the characterizing features of claim 1.

As a result of the inventive training a light one The screw cap can also be opened with larger cover sizes by means of pliers, which have pliers legs connected in the center in the manner of conventional household pliers.

Preferably there is on the outer edge of each plier leg in the jaw area between two projections arranged a recess, which is suitable both for lifting lids and for opening crown corks.

Due to the arrangement of two projections in the jaw area at the outermost ends of the pliers legs is through the

- 1 9098U / 0355

large distance between the jaws on each plier arm located two projections the attachment of a crown cap opener or a device for lifting Allows covers, so that the screw cap pliers is particularly cheap in practical use, since they are independent whether the outer or inner protrusions are to be used, in the correct position for lifting at all times of the lid and to open crown corks lies in the hand. In contrast, it is with pliers that only one Side have a crown cork opener, which may be necessary, the pliers in each case by turning them into the correct one Bring the opening position for actuating the crown cap opener.

The invention will then be described using an exemplary embodiment shown in the accompanying drawing. Show it:

Fig. 1 is a plan view of that side of the screw cap pliers, which is intended for opening relatively large screw caps and in which the projections are on the outer edge of the pliers legs,

2 shows a plan view of the other side of the pliers, in which the projections are arranged on the inner edge of the pliers legs are and are therefore used to grip screw caps with smaller diameters, and

Fig. 3 is a side view of the pliers.

The two pliers legs 2 and 3 of the pliers 1 are ^{articulated to one another at 1} I between the handle and the gripping organs of the pliers. On one side of the pliers, the projections 5a, 5b, 5c and 5d are arranged on the outer edge of the pliers legs, while on the other side of the pliers, the projections 6a, 6b, 6c and 6d on the inner edge of the pliers

thighs lie so that their mutual distance from each other is smaller compared to the corresponding distance between the projections 5a to 5d, so that the detection of smaller cover sizes becomes possible. In plan view, both projections have an obtuse-angled shape with an outward-pointing tip or are more curved than the circumference of the smallest screw cap that can be grasped, so that the inner edges of the projections each act as wedges on the screw cap circumference create a slight indentation in each case, which is sufficient to deform the screw cap in such a way that the tight contact the lid surface on the jar is released and the vacuum in the can is removed. After removing the vacuum, a light one is sufficient Unscrew the lid to open the can effortlessly.

The projections each protrude in the direction of the pivot pin on both sides of the pliers plane by one each To grasp the cover easily.

Due to the symmetrical arrangement of two projections 5b, 5c and 6b, 6c at the end of the two pliers legs it is also possible to grasp relatively large can lids at a favorable angle of attack.

In addition, the arrangement of the projections located at the ends of the pliers legs makes a relatively large one Distance between the two projections of each plier leg created, so that this space for arrangement an opener formed by recesses 9, 10 for crown caps is available, which is also used for lifting lids can be used.

On the inner edge of the two legs, two ring gears 7 and 8 are provided as gripping organs, which a detection of Enable can lids with particularly small diameters.

The ring gears 7, 8 protrude inwardly from the inner projections, so that the ring gears open rest on a cover that is to be gripped by the inner projections. When grabbing one Cover by means of the outer projections, essentially the entire pliers leg rests in the jaw area the screw cap. This prevents the screw cap pliers from slipping downwards. The protrusions 6a, 6b, 6c and 6d are symmetrical to the longitudinal axis of the pliers.

The screw cap pliers are provided with dishwasher-safe plastic handles H in the grip area.

Claims (5)

Expectations 1. Screw-cap pliers, the two pliers legs of which protrude from the pliers level on each plier side forming projections are provided which are used to rest on the circumference of a screw cap, the projections on the one side of the pliers a greater distance from one another each other than the projections on the other side of the pliers and the pliers legs between one The handle and the jaw area are articulated to one another, characterized in that that four projections are provided on each pliers side, two of which (5b, 5c; 6b, 6c) on the front and two (5a, 5d; 6a, 6d) are arranged at the rear end of the jaw area, that the projections on one side of the pliers on the outer edge of the legs and the projections on the other side of the pliers lie on the inner edge of the pliers legs and that the projections (5a, 6b, 5c, 5d; 6a, 6b, 6c, 6d) are more curved in the circumferential direction than the smallest Screw cap on which they come to rest, so that the inner end edges of each protrusion act as wedges act that create local indentations of the lid circumference, thereby eliminating the vacuum in the glass. 2. Screw cap pliers according to claim 1, characterized in that on the outer edge of each plier leg between two projections each have a recess (9, 10) is arranged, which is used both for lifting lids as well as for opening of crown corks and two limiting the recess, having opposing hooks. 9098U / 0355 010977 3. Screw cap pliers according to claim 1, characterized in that the pliers legs have two toothed rings on their inner edge (7, 8), which are used to open screw caps. A. Screw cap pliers according to claim 2, characterized in that the one toothed ring (7) is arranged between the projections of the two pliers legs and the other toothed ring (8) is arranged between the hinge point of the two plier legs and the projections of the rear end of the jaw area. 5. screw cap pliers according to claim 1, characterized in that the projections of one leg (6a, 6b; 5c, 5d) symmetrically with respect to the longitudinal axis of the pliers to the projections of the other leg (6c, 6d; 5a, 6b) lie. 9098U / 0355
