Abstract
Description
[0001] The invention relates to an adjustable, multifunctional opening aid, e.g., for twist-off closures made of plastic or metal on standard packaging made of plastic, metal, or glass. This also applies to packaging opened with ring-pull tabs or crown cap closures. Particularly when packaging becomes damp and therefore slippery due to cooling, considerable force is required for the initial opening. State of the art
[0002] Numerous bottle opener designs for twist-off caps have been developed to improve their ease of use. For example, radially slotted rings (DE 229 15 019 U1) feature grip projections around their circumference. The receiving bores consist of stepped cylindrical sections, allowing the screw cap to be inserted into one of these bores, which, when the slotted ring is squeezed, generates the necessary torque.
[0003] The required force cannot be exerted by older and physically impaired people.
[0004] A bottle opener (DE 299 08 450 U1) is also known as a closed ring with a conical receiving bore into which the drive pins protrude. This requires that the bottle opener be pressed axially with sufficient force and simultaneously rotated, which is also difficult for elderly and physically impaired persons to perform.
[0005] The solution to the problems posed arises from a new state of the art. One such embodiment of the invention is described with reference to the drawings.
[0006] This shows Fig. 1. An adjustable, multifunctional opening aid for twist locks of various diameters and shapes. Fig. 2 the same adjustable multifunctional opening aid, but with an insert used at the end of the handle for rinpull tabs when opening a can. Fig. 3.

[0007] The invention is based on the objective of creating an adjustable, multifunctional opening aid suitable for effortlessly opening screw caps of beverage, vinegar, and oil bottles, sauces, and much more, in a wide variety of diameters, as well as packages with ring-pull or crown cap closures. This requires that the necessary force be generated by a large leverage effect.
[0008] The use of a large handle on the base of such an opening aid allows for the use of interchangeable tools at the end of the lever. These are suitable, for example, for opening cans and tins with ring-pull tabs. Pasteurized packages with screw caps are also easier to open if the vacuum is first broken by venting. By changing the tool, crown caps can also be opened; this is particularly useful in Fig. 15 can be seen.
[0009] In the illustrated embodiment in Fig. Figure 3 of the adjustable multifunctional opening aid shows a base body 1 with handle 11 and a polygonal closure cover 6 with rounded corners, as well as an adjusting slider 2, a cam disc 3, and at least three sliders 4 assembled together, all made of plastic except for the drive lugs 9, which are made of stainless steel. The adjustment of the three sliders 4 to different sized screw caps is achieved by the cam disc 3. For this purpose, a cylindrical pin 10 engages in a corresponding groove 31 of the cam disc 3, so that when the cam disc 3 is rotated, the sliders 4 and their guide grooves 43, in conjunction with the closure plate 6 and its guide rails 61, can move radially within the base body.This moves spring-loaded drivers 9 until they contact the rotary lock to be opened, causing the engagement edges 91 to bite into the rotary lock. A detailed illustration of the gripping mechanism is shown in . Fig. 8, Fig. 9, Fig. 10 to Fig. 11 can be seen.
[0010] These illustrations show a compression spring 10d, which serves to hold the driver 9 in position. The cylindrical pin 10 connects to the cam disk 3 and engages in its cam grooves 31. The driver 9, with its engagement edge 91 and contact surface 92, the guide grooves 43 which slide in the guide rails of the locking plate 6, and the slide cover 5 with its connecting pins 51 which form the end of the gripping mechanism in the connecting holes 41 of the slide base are also shown.
[0011] In terms of handling, the spring-loaded drivers 9 create a ratchet-like function, which also makes it possible for people with limited manual functions to perform a simple opening process with small rotary movements and the large rotation of the lever 11.
[0012] The existing lever 11 with its pocket 15 for different tools 7a and 7b also creates the possibility to open packaging which is closed by ring pull tabs or crown cap closures.
