Abstract

Screw cap opener with size adjustment including:
- a housing-like base body (1), a rubberized handle (11), a circular elongated hole (12), a removal hole for the screw cap (13) and a hanging hole (14),
- a grid adjustment system that adapts to the different screw cap sizes,
- whereby the grid adjustment system consists of the following positions:
Return spring (2), round slide (3), grid lever (4), cam disk (5) with the grid arches (51) attached therein, cam grooves (52), cams (53 + 54), and the rotary cam (55)
- have a gripping mechanism made up of at least three slides (6+7) of circular shape, each with a niche (72), in which a driver (9) made of stainless steel in a U-shape and a compression spring (11) which holds the driver (9) always in position, a cylindrical pin (10), which is guided in the cam grooves (52) of the cam disk (5) and interacts with the guide grooves (73) of the lower slide part (7) and the guide rails (81) of the closure cover ( 8), radially to the base body (1) can assume an inner position with the smallest opening size, or a radially outer position with the largest opening size, or an intermediate position.
- a closure cover (8) for closing the base body (1), the closure cover having three pairs of guide rails (81) in which the slides (7) are guided with their guide grooves (73), and a mouth opening (82), which serves as access for the screw caps to be opened.

Description

The invention relates to a screw cap opener with automatic size adjustment for screw caps made of plastic or metal on commercially available packaging for thin and thick liquid goods.

State of the art

An opening aid for screw caps is known ( DE 20 2015 001237 U1 ) which makes it easier to open screw caps of certain diameters. However, screw caps with different large diameters cannot be opened.

Task

The invention is based on the object of developing a screw cap opener which is able to independently adapt to the respective diameters of a certain size.

The solution to the task arises from the claims and is additionally described using drawings.

Da Pos. 15 auf der Pos. 55 der Kurvenscheibe 5 sitzt und diese mit einer Rückholfeder 2 verbunden ist, kann nun die Daumenbewegung beendet werden und die Rückholfeder 2 zieht den gesamten Verstellmechanismus so zusammen, dass der Mitnehmer 9 zum Eingriff kommt und die Schraubkappe mit einer Linksdrehung geöffnet werden kann. Dieser Vorgang wird in 4 + 5 nochmals detailliert beschrieben.

Jetzt zeigt es sich warum ein Rasterbogen im Mechanismus eingeplant ist, in dieser Situation kann selbst bei einem schwierigen Öffnungsvorgang nichts mehr durchrutschen, das verhindern in Zusammenarbeit der Rasterhebel 4 und die Rasterstange 51 der Kurvenscheibe 5. Nach dem Öffnungsvorgang und Entfernung der Schraubkappe bringt die Rückholfeder 2 in Verbindung mit dem Drehnocken 55 auf der Kurvenscheibe 5 den gesamten Verstellmechanismus in Endstellung wie in 4 gezeigt wird. Am Ende dieses Rückholvorganges wird durch den Nocken 53 auf der Kurvenscheibe 5 über den Anschlag 32 der Schlittenrand 36 des Rundschlittens 3 zwischen den Rasterhebel 4 und Rasterbogen 51 der Kurvenscheibe 5 geschoben und in der kleinsten Durchmesser Einstellung so gehalten.

This shows:

• 1 The handling of the screw cap opener in a perspective view, using the thumb over position 15, turn it counterclockwise to the largest holder and place it on the screw cap to be opened. Since position 15 sits on position 55 of the cam 5 and this is connected to a return spring 2, the thumb movement can now be stopped and the return spring 2 pulls the entire adjustment mechanism together so that the driver 9 comes into engagement and the screw cap with it can be opened by turning to the left. This process is carried out in 4 + 5 described again in detail.
• 2 like an exploded perspective drawing in which all essential parts of the screw cap opener are clearly visible.
• 3 here the screw cap opener from the bottom and at the same time the first assembly structure with the base body 1, the return spring 2, the round slide 3, the ratchet lever 4, the compression spring 41, the anchoring 21 of the return spring 2, the position and stop point 22 of the return spring 2, which at the same time is also the smallest size setting, as well as a cylinder pin 16, which is anchored in the base body 1 and also serves to hold the ratchet lever 4.
• 4 the smallest diameter setting and is a further assembly structure with the cam 5 which represents the central point in the entire adjustment system. It is automatically brought into this position by the return spring 2 via the rotary cam 55 of the cam 5, while its cam 53 hits the stop 32 of the Round slide 3, the slide edge 36 stands between the grid lever 4 and the grid arch 51 of the cam 5 and prevents it from engaging until a new opening process is carried out.
• 5 the largest possible diameter setting, when approaching this largest position, the cam 54 on the cam 5 releases the stop 33 of the round slide 3, so that the grid lever 4 can latch into the grid arc 51, it can be seen that the position 10 over the Cam grooves 52 have reached their final position in the cam and thus the gripping mechanism 6-11 is in its largest setting or rests against the screw cap on the packaging. Now it becomes clear why a grid arch is planned in the mechanism, in this situation nothing can slip through even with a difficult opening process, the grid lever 4 and the grid rod 51 of the cam disk 5 work together to prevent this. After the opening process and removal of the screw cap, the return spring comes 2 in conjunction with the rotary cam 55 on the cam 5 the entire adjustment mechanism in the end position as in 4 will be shown. At the end of this return process, the cam 53 on the cam 5 pushes the slide edge 36 of the round slide 3 between the grid lever 4 and grid arch 51 of the cam 5 over the stop 32 and holds it in the smallest diameter setting. In this position, most beverage closures can be opened without any further changes.
