Abstract

Beverage can pull tab with integrated closure function, which preferably consists of the same material as the beverage can itself
- Wherein this is made slightly larger than that in the cover plate (5) existing drinking opening (10) and an actuating element (8), which by lifting the first opening in this position opposite her predetermined breaking point (10) (Fig.3 ) in the cover plate (5), which is defined after the first opening the Trinköffnungsrand used, and after a rotation of 180 ° about a rivet (6) for closing the drinking opening (10) can be used, characterized in that the actuating element (8) by means of one or more defined arranged beads (3) and / or (7) in the closed position (Figure 4) in opposition to the actuating element (8), relatively firmly on the edge of the drinking opening (10), ie a part of the cover plate (5) is pressed because the closure (1) on the rotatably riveted and on the cover plate (5) adjacent inner tab (2) can not be raised and thus on the inner flap (2) a kind Leverage between the bead / s (3) and (7) and the actuating element (8) is exercised and wherein the bead (3) on the closure (1) can also be generated by crimping the closure edge.

Description

This is preferably a one-piece made of aluminum, multifunctional Dosenaufreißlasche for commercial cans, mostly beverage cans made of aluminum, which can be used after the first opening of the can as a closure of the drinking opening, so that then neither coarse dirt nor insects can get into the can interior and that easily and safely, even with one hand, is operable.

The previous opening principle with the aid of an opening tab, which remains after opening the can, does not currently constructively after the first opening, the contents of the can effectively protect against dirt or insects.

The can thus remains virtually open until completely empty. During this time, insects such as flies, wasps, bees or similar animals, as well as coarse dirt can enter unhindered into the can. Due to the opacity of metal cans, the user can now hardly control until the contents are completely consumed, whether such things are now in the can. This fact represents for the consumer, especially with regard to invaded insects a not to be underestimated risk to health.

Securing the cans (usually beverage cans) with additional caps, beer mats, cell phones or the like, are cumbersome in practice compared to the new invention, impractical and uncertain.

State of the art:

There is currently no accepted by the beverage industry as mass suitable for use, easy-to-use, safe functioning and without significant additional cost inexpensive to produce system on the market, with which can easily open and without fingerhakeln or jigsaw play one-handed safe and can be closed again and which the aforementioned Purpose corresponds without changing the character of a simple disposable can. Either the systems do not readily fit into conventional bottling plants, are expensive and complicated to manufacture, not safe to function, too cumbersome to serve, or they are largely made of plastic elements.

This problem is solved with the features listed in the protection claim 1.

By the invention, contamination of the contents of the can be prevented immediately and safely without additional effort. The can closure is structurally designed so that the can opening can be closed again after the first opening by means of the can closure itself, by a rotational movement of the closure 1 is made slightly larger than the respective drinking opening itself.

The ability to close the cans is thus present on each unit purchased and readily available without additional expense and expense, because the can closure is and will be connected to the can before and after opening.

Furthermore, the invention allows the use of the finished can lids in all conventional filling systems, as rest through the structurally flat design of the closure, the lid on the side edge recesses present to each other without increasing the height commercial lid. The intervening closure does not carry so far on the one another or overlying lid over this tilt.

Advantages:

• - No more danger from invading insects or coarse dirt
• - easy handling also for children
• - to operate with one hand (important for example in vehicles)
• - Usability in all conventional can filling lines
• - no additional materials such as plastic or similar
• - complete recyclability of the can is retained
• - Stackability remains fully intact
• - no gross spillage of contents with upright or held cans and slight shaking movements (important in vehicles)

How it works:

By lifting the actuator 8th pushes the opposite part of the closure 1 in the cover plate ( 5 ) self-predetermined breaking point ( 10 ) ( 3 ) of the drinking opening ( 9 ) and opens the box in a known manner for the first time ( 4 ). Then you press the shutter 1 back to the cover plate 5 , Due to the tension of the resulting kink between closure 1 and inner flap 2 can the shutter 1 but not exactly to the cover plate 5 invest. This effect is already known in conventional pull tabs (Stay on tabs). Now you turn the shutter 1 to cover 180 ° degrees around the drinking opening, then lies the shutter 1 by this voltage actually not close to the cover plate. But to make this possible, there is a cover plate side at the bottom of the closure 1 in preferred and shown embodiment ( 1 ) one or more beads 3 , In the cover plate 5 are also one or more beads 7 arranged so that the bead (s) 3 of the closure 1 in a locked position runs on these ( 4 ). By pushing both beads over each other is the opposite actuator 8th of the lock 1 pressed down so that it with light voltage produced on the cover plate 5 pressed.

Thus, the actuator is located 8th , which is slightly larger than the drinking opening ( 9 ) itself, according to the purpose close to the cover plate ( 5 ) on. If the closure is made by Umfalzverfahren from thin sheet metal, the round folded edge can here also as a bead 3 be executed.

To better operate and turn the shutter 1 is a slider at this 4 formed. It must be designed in such a way that from its height it does not interfere with a new lid which has not yet been folded on the can and makes it wobble. However, a slider element can also be used in the closure 1 on the actuator 8th to get integrated.

To the closure 1 The inner flap is pressed as tightly and firmly against the lid as possible 2 so executed, that before riveting on the cover plate 5 is arranged slightly higher than the bottom edge of the closure 1 , which in the embodiment shown here ( 2 ) through the bead 3 is formed.

When riveting the inner flap 2 Now pressed down under tension and riveted and is thus directly on the cover plate 5 on ( 3 ).

As the inner flap 2 and the closure 1 are made in one piece and thus are firmly connected to each other, the voltage of the pressed-inner tab transmits to the closure 1 , This corresponds to a kind of knock-down function.

In order to achieve a lock in the closed state, the beads can 3 and 7 be designed in contrast so that the one engages in a predetermined recess of the other. Here, however, must be taken to ensure that by the latching process not too much height of the superimposed beads 3 and 7 is lost and thus no longer sufficient contact pressure of the actuator 8th is transferred to the edge of the drinking opening.

For closures made of thin sheet metal, which give the rim a pipe-like structure to reinforce the stability, one or more can be placed on the cover sheet 5 arranged side by side correspondingly high beads 7 already give the necessary height to the / which opposite actuator 8th Purpose to press firmly on the outer edge of the drinking opening when these areas push each other during rotation in the closed position. The downwards tube-like folded structure of the closure 1 assumes the function of the bead with appropriate shaping in this case 3 ,
