EP2388230B1 - Rotating opener, particularly for twist tops of bottles or similar - Google Patents

Description

The invention relates to a rotary opener, especially for screw caps of bottles or the like., In which two clamping brackets in each of which a clamping half-shell is fitted.

State of the art:

Numerous rotary openers have become known, which embrace the bottle caps and are pressed by hand on the closure. Also, such rotary openers are equipped with springs, these springs move the clamp in an open position. A generic rotary opener is from the GB2275918 known.

Object of the invention:

The invention is based on the object to provide a rotary opener, which is suitable for the presentation of drinks (wine, sparkling wine, soft drinks) in the catering and other uses and allows easy table opening the more often used rotary shutters. Also for opening any screw caps of the rotary opener invention can be used.

Solution of the task:

The object is achieved in that at least one tooth in the rotary closure encompassing clamping shells of the clamp is pressed by at least one spring shape and / or frictional engagement with the rotary closure.

Effects of the invention:

The opener has stops 1 and 2, with which it is immediately attached to the correct position on the closure. Clamping brackets 4 and 5 with integrated teeth 7 and 8 are pressed with one or more springs 11 on the screw cap. These teeth 7, 8 engage in the knurling or other executed rotary fasteners form fit. As springs 11, both coil springs, leaf springs and tension coil springs (in the region of the clamp) can be used. The hinge joints (9) make the movable connection and thus the uniform force approach to the rotary closure between the clamping brackets 4 and 5 ago. Furthermore, the hinge joints (9) allow the size of the opener to cover the entire range. As soon as the opener has been attached to the screw cap, the spring force automatically holds the opener.

Thus, the operator in the catering (or other use) are always both hands to offer and open the beverage bottle (wine bottle) freely available. By the beginning of manual rotary motion and thus a further dosed pressure on the screw cap, breaking the perforated line or the breaking point of the closure, in a rotatable and fixed part. The fixed part remains on the container and had the task of preventing an unwanted opening. The further rotational movement until removal of the rotary closure takes place without further manual pressure on the rotary closure, since the springs 11 constantly exert so much pressure that the opener remains pressed against the closure. The spring pressure acts on the clamping brackets 4, 5 in the entire opening area of the rotary closure. There is thus the possibility for further rotation of the shutter insert only one finger in the final rounding 12 of the opener.

The rotational movement can be carried out both on the screw cap, on the container or on both objects at the same time. After removal of the rotary closure this remains trapped in the opener in the clamping shell 6. It is by manual opening of the clamps 4 and 5 in which a back pressure on the springs 11 of the rotary closure is released and can be removed. Must in other known rotary openers a constant physical pressing force are applied to the or the opening bow, etc. so firmly pressed against the closure to reach the contact force for opening when opening is in representational opener in addition a supporting spring force, whichever type used. After breaking the perforation or predetermined breaking point, no further physical contact force is required in the further rotation of the closure, since the spring pressure presses the clamps 4, 5 immovably on the screw cap. The spring pressure is throughout

Opening range of the rotary closure effective and will be equipped depending on the required pressure. The rotational movement can be carried out both on the screw cap, on the container or on both objects at the same time. After removal of the rotary closure this remains trapped in the opener. It is open by manually opening the clamp 4, 5 in which a back pressure on the springs 11 of the rotary closure is free and can be removed. The embossments 14 on the clamping brackets 4, 5 should u.a. be used for promotional purposes. Any existing recesses (openings) 13 are used to facilitate weight. All construction parts can be made of metal, steel, wood, stone, ceramics, plastics and other materials. Moreover, the clamping brackets 4, 5 of the rotary opener according to the invention can be made of a flat blank. The production by a casting - pressing method of metal, plastic or other moldable materials is possible and provided.

Aufzählung and brief descriptions of the drawings:

In the drawings, the subject invention is shown as an expedient embodiment.

Description of the figures :

General description of all parts in the figures shown.

Height stop 1, 2 of the opener on the screw cap, connected to the stop connections 3 and to the clamping brackets 4, 5. With the integrated teeth 7, 8 which are connected to the clamping brackets 4, 5 and related to the hinge - joints 9, thereby the contact pressure on the closure is evenly distributed. Teeth 7, 8 for firm and non-slip attack on the screw cap which are integrated in the clamping shells 6. Hinge - hinge 9, which connects the clamps 4, 5 and optionally allows a corresponding opening size of the opener and divides a uniform distributed pressure on the closure. Hinge - hinge 9 and spring (s) 11, press the clamps 4, 5 to the screw cap. End rounding 12 makes it possible with one finger after breaking the perforation or predetermined breaking point to carry out the further opening rotary movement.

Fig. 5 and Fig. 6 serve for better illustration.
