Description

technical field

The invention relates to a beverage can according to the preamble of claim 1.

Beverage cans with a closure flap that cannot be lost after opening have established themselves on the market.

Compared to beverage bottles, these have the disadvantage that the closure remains open after opening, which does not prevent dirt or insects, e.g. bees, from getting in or spilling the beverage.

Numerous attempts have been made to find a solution to remedy this problem, but have not been implemented in practice.

A further problem arises when the prefabricated lid parts of the beverage can are to be stackable to save space and the closure is to fit snugly on the lid part when the can opening is to be closed again after the tab has been torn open.

State of the art

A beverage can of the type mentioned is from DE 195 42 101 A1 famous. This has an actuating part with a dual function, namely on the one hand to open and on the other hand to close the removal opening. A plate-shaped closure and an opposite opening part are rotatably fastened to the lid part with a rivet connection. An embodiment described there provides that the outline of the closure corresponds approximately to the opening cross section or is slightly smaller and that the closure can be pivoted into the opening cross section. A largely tight resealing of the removal opening is thus possible. At the edge of the opening and/or on the outer edge of the closure, hooking elements can be provided for the detachable connection of the closure to the cover part. As a result, the closure is additionally secured in the closed position.

Another solution for reclosing a beverage can is in the DE 297 14 210 U1 shown and described. The integrated, rotatable actuating part or a handle can also be used as a can lid. The underside of the handle or the closure body is designed with a projection, bead or the like, so that it can be pressed into the opening for the purpose of closing it.

In the AT 502 592 A1 it is proposed, in addition to the conventional first opening part, to provide a second closure part, which can be rotated relative to the first part and is attached to the beverage can with the same rivet connection. The clasp can be opened and closed with another 5 mm rivet.

Another sealable pull tab for beverage cans is from the DE 91 09 081 U famous. There, the tear-off tab is provided with a latching and sealing element or a lip element that causes a latching and sealing position. The latching and sealing element is thus designed as an elastic lip element encompassing the edge of the tear-off tab. When closed, the tear-off flap covers the outlet opening. This covering position is achieved in that the tear-off tab is rotated over the pivot point by slightly lifting it with the lip element over the outlet opening. It is also possible to arrange a spring or pressure part to apply firmer pressure to the outlet opening. Turning or lifting is facilitated by a ridge on the pull tab.

Another version with a sealing lip is from DE 200 06 176 U1 famous.

A tab or fold should be attached to the rear part of the opening flap. This lug rests on the can lid when the opening tab is turned. The opening flap is thereby pressed down at the front and the possible gap is reduced. An elevation or a bar on the opening tab makes it easier to turn. However, this lug is arranged on the opening tab and not directly on the cover plate, which is disadvantageous. This lug is already in contact with the cover plate before the first opening, which has a disadvantageous effect when many cover plates are stacked. Furthermore, a desired later leverage is not generated by the nose, or only insufficiently, since it is always on the same level, no matter in which position.

the DE 202019001207 U1 discloses a beverage can with a tear-off tab and with an integrated closure function. A cover bead is used to improve the closure.

In the pamphlet DE 202018002847 U1 discloses a can closure in which a can closure member carries a slightly downwardly angled tongue to provide a clamp that causes the can closure member to fit snugly against the can end when the beverage can is resealed.

Another beverage can with an integrated can closure is from the DE 10 2018 133 278 A1 famous. This solution means that the can closure comprises a closure part for closing a beverage can opening arranged on a lid part and an opening part for opening or tearing open the beverage can opening. The beverage can opening is provided with a closure tab connected in one piece via a tear line prior to an opening process, which is held captive on a beverage can body after opening by the opening part, the closure part and the opening part being firmly connected to one another and being rotatable via a pivot point on the beverage can body and being Closure part, a holding element is arranged, which is designed to bring about a detachable connection of the closure part with the ceiling part. The retaining element is designed as an element that slides in underneath the cover part during a rotary movement in order to prevent the closure part from being lifted up in a closed position.

object of the invention

The invention is based on the object of creating a beverage can of the type mentioned at the outset which, on the one hand, allows the beverage can to be resealed securely and in a user-friendly manner with minimal design effort and, on the other hand, allows prefabricated can lids to be stacked in a space-saving manner, with good resealing being to be ensured.

Solution and advantages of the invention

This object is achieved by the features specified in the characterizing part of claim 1 in conjunction with its preamble features.

The invention is based on the idea that by lifting one end of the can closure, the opposite end, the closure tab, is pressed down onto the edge of the drinking opening like a lever. Pressing down improves the closing behavior. This ensures a good reclosure. The missing tongue also makes it easier to stack the lid parts. One-hand operation is not lost here.

Other advantages are: no more danger from penetrating insects or dirt, easy handling even for children, can be used with one hand (important e.g. in vehicles), only minor changes to the can lid are necessary, no additional materials, complete recyclability remains unrestricted, stackability remains in fully preserved, no significant additional manufacturing costs, no gross spillage of the contents with upright or held cans and slight shaking movements (important in vehicles).

Advantageous configurations of the invention and further advantages

Further advantageous developments of the invention are characterized in the dependent claims.

In an advantageous development of the beverage can according to the invention, it is provided that the ramp is designed as a ramp-shaped bead. This can be easily made.

A particularly preferred development of the invention is characterized in that the ramp is arranged in the vicinity (3 mm-10 mm or 4-6 mm) of a rivet connection forming the axis of rotation of the closure part, opposite the beverage can opening. This position is optimal for the manufacture of the can ends. This is further improved if the ramp is arranged between a trough and the can closure in a delivery state.

It is of particular advantage if the ramp is placed between at least one, preferably two, spacer beads and a pivot point of the closure part, the ramp having a greater height than the spacer bead and the spacer bead interacting with a depression (free space) of the closure part in a delivery state . Due to the relatively large height of the ramp, a large force acts on the closure flap when it is intended to close the drinking opening. However, the height of the ramp is not a problem if it dips into a free space in the closure part, so that prefabricated cover parts can be stacked better ( 5 ).

It is particularly expedient for operation and manufacture if a finger-operable sliding element is formed or bent in one piece on the closure part.

The finished lid parts can be easily stacked if the sliding element is designed as a web that protrudes perpendicularly or at an angle, in particular 15° to 80°, preferably 20° to 80°, in particular 20° to 50°, towards the closure part and is preferably arranged essentially in the front closure part area is.

1 shows a can closure 1, which is integrated into a beverage can, not shown.

The beverage can is made of sheet aluminum. The can closure 1 comprises a closure part 2 for closing a beverage can opening 4 arranged on a lid part 3 and an opening part 5 or opening section on the closure part 2 for opening or tearing open the beverage can opening. Parts 2 and 5 are made in one piece.

The beverage can opening 4 is provided with a closure flap 7 connected in one piece via a tear line 6 prior to an opening process. This is captively held on the beverage can body 8 in a known manner after opening by the opening part 5 .

The closure part 2 and the opening part 5 are thus firmly connected to one another, arranged offset by 180° and rotatably fastened to the beverage can body 8 via a pivot point 9 or a rivet connection of a known type. In the closed position, the closure part 2 covers the drinking opening 4 ( 6 ).

In contrast to other solutions, there is no retaining element, such as a retaining tongue, arranged on the closure part 2, which is designed to bring about a detachable connection of the closure part 2 to the cover part 3, namely in order to lift the closure part 2 in one or in to prevent its locking position.

Instead, a ramp 10 or a ramp-shaped bead is used, which is arranged on the cover part 3 or inside the so-called mirror 11 (trough-shaped recess). The ramp 10 protrudes almost upwards when the can is, as in the 2 until 4 is shown. The ramp 10 ensures that one end 12 of the closure part 2 is moved upwards (arrow direction B in 4 ) when the locking part 2 is rotated 180° in the direction of arrow A ( 3 ) opposite the in 1 shown position is rotated. the 5 and 6 show this process. 5 shows the can closure 2 as delivered. This is mainly located at a distance from the drinking opening or beverage can opening 4 ( 5 ). In a known manner, one end 13 is lifted so that the end 12 is pressed downwards in a lever-like manner and, in a known manner, frees the opening 4 by pressing a portion 14 of the lid downwards, e.g 6 displays. The closure part 2 is then rotated through 180°, from the in 5 position shown in the in 6 position shown. Then the closure part 2 is located over the opening and covers it. The end 12 moves over the ramp 10, such as 6 displays. The end 12 rises upwards, like 4 points, and lever-like moves the opposite end (13) ( 1 ) something down, like 6 displays. This causes the closure part to fit snugly against the opening 4 and seal it well, at least in such a way that no insect or crawling animal, such as an ant, or dirt can get into the can. Even if the can falls over, little or no spills. The content does not run out suddenly, as with conventional cans. If the can falls over, the user can set it up in time before a lot of flew fluid exits from the largely sealed opening. Insects etc. are prevented from entering by the invention. A side effect is the sealing, which does not have to be 100%. It is true that the arrangement of elastic sealing material would be possible, which would improve the seal, but the production should be inexpensive, so that an additional seal can be dispensed with.

The finger-actuable sliding element 14 is also integrally formed on the closure part 2 and is preferably bent upwards. In the embodiment described here, the sliding element 14 is designed as a vertical to angular, in particular with a first angle ( DE 10 2018 133 278 A1 ) from 60° to 80° ( DE 10 2018 133 278 A1 ), to the closure part 2 protruding web executed. The web is essentially arranged in the front closure part area and, for example, at an angle of 15° to 30° ( DE 102018133278 A1 ) arranged from a vertical axis. In order to avoid the risk of injury, there may be a bulge at the top of the bar. The shape of the web or of the element 14 can be trapezoidal, but also have another shape. This design of the closure is advantageous due to the good stackability of the delivered lids lying one behind the other, which are delivered packed in rolls and then delivered to the bottling plant ( DE 1020181333278 A1 ). Because of the ramp that replaces a tongue, stackability is further improved.

It is possible to position the closure 2 over the opening 4 of the cover plate without any particular skill, using only a finger or thumb. During the operation of the closure 1 with the sliding element 14, this is automatically not only moved in the closing direction, but also pushed slightly downwards by the ramp 10.

The plate-shaped closure part 2 is in the closed position ( 6 ) embedded within the mirror 11 (trough-shaped depression). This section is also referred to as trough 25 or mirror 11 here.

How it works is as follows:

When delivered, the closure 1 is arranged opposite the drinking opening 4 ( 1 , 5 ).

Then the user lifts the closing part end 13 upwards in the manner of a lever. A flap 7 closing the drinking opening tears in a known manner as a result of the end of the closing part 2 moving downwards and releases the drinking opening.

After that, the user rotates the shutter 2 180 ° ( 6 ) to close the opening 5 again when he has drunk. The drinking cap is in 6 shown in closed position. The can closure 1 lies within the border 18 ( 1 ) or tub 25 ( 5 ).

To open it again, the user turns the closure in the opposite direction of rotation until the drinking opening is exposed, with the drinking opening being able to be opened and closed as desired by turning.

To produce the beverage can, the ramp 10 is punched out of the sheet metal of the lid.

As the 5 until 7 show, two elevations 15 (distance beads) are arranged within the trough 25 in such a way that the closure 2 protrudes slightly at the end 13 when delivered ( 5 ) so that a fingernail can reach into the gap 25 formed in a known manner so that the opening 4 tears open. 8th shows a recess 16 of the closure part 2, which in the delivery state with the beads 15 ( 7 ) works.

Before fastening the closure 1, the cover part 3 or cover plate is prepared, i.e. the trough 25 is formed, the tear line is formed, etc.

The finished closure part 2 is riveted to the beverage can body 8 or the lid part 3, including all finished elements such as the sliding element 14 etc. The closure 1 is a stamped and bent part.

The edge 21 of the closure part 2 is preferably beaded so that it is dimensionally stable. In order to open the opening 4 better, a U-shaped incision 22 is arranged on the closure part 2 in a known manner. To improve the tearing behavior, a U-shaped indentation 23 is arranged on the flap in a known manner. In addition, two spacer beads are arranged on the lid part inside the trough 25, so that the can can be opened better the first time in a known manner.

9 shows a preferred variant of the ramp 10, which has approximately a semicircular shape. This has, compared to the variant according to 2 until 4 , two flat ends 26 and 27 and a ramp peak 29 in the middle. how 10 12 the ramp 10 is symmetrical (line of symmetry 28). The ramp is basically two ramps or a double ramp. The ramp is provided in the radius of the pivot point or a rivet connection 30 for the closure part 2, which mounts it rotatably on the cover part 3.

A beverage can with an integrated can closure 1 ( 1 ), whereby the can closure 1 has a rotatable closure part 2 ( 5 , 6 ) for closing a beverage can opening 4 arranged on a lid part 3 and designed as a drinking opening, and an opening part 5 for opening or tearing open the beverage can opening 4 ( 6 ), the beverage can opening 4 is integrally connected to a closure tab 7 ( 1 ) is provided, which after opening is captively held by the opening part 5 on a beverage can body 8 ( 6 ), wherein the closure part 2 and the opening part 5 are firmly connected to one another and can be rotated via a rotation axis 9 on the beverage can body 8 ( 5 , 6 ), as well as in the DE 102018133278 A1 is described, wherein the cover part 3 has a ramp 10 ( 2 until 4 ) is arranged in such a way that the closure part 2 is pressed against the beverage can opening 4 when screwed in ( 6 ).

Because the closure part 2 and the opening part 5 are firmly connected to one another and can be rotated on the beverage can body 8 via an axis of rotation 9 , the closure part 2 can close the beverage can opening 4 in the closed position.

The prefabricated lid part can be easily stacked because a ramp 10 is arranged on the lid part 3 in such a way that the closure part 2 is pressed against the edge 21 of the beverage can opening 4 when it is screwed in.

The ramp 10 is designed as a ramp-shaped bead. The ramp 10 is arranged in the vicinity of the riveted connection (axis 9) forming the axis of rotation 9 of the closure part 2 opposite the beverage can opening 4 ( 1 ). The ramp 1) is in a delivery state ( 5 ) between a trough 25 and the can closure 2 is arranged.

The ramp 10 is placed between two spacer beads 15 and a pivot point 9 of the closure part (2), the ramp 10 having a greater height than the spacer bead 15, and the spacer bead 15 interacts with a depression 16 of the closure part 2 in a delivery state ( 6 ), which is explained below.

1 shows two spacing beads 11, which are arranged side by side and horizontally at the same height and relatively high up. the 1 shows a view as if the can were lying down, with the can lid lying upright on a support (eg a table). At a relatively large distance from the beads 15 (base), the pivot point 9 is placed below, the pivot point 9 being closer to the base and this height corresponding to the radius of the can. Between the upper height of the beads 15 and the lower height of the pivot point 9, the ramp 10 is approximately in the mid-height range. The ramp is closer to the base than the beads 15 but further away than the pivot point 9. Ramp 10 is therefore placed between at least one, preferably two, spacer beads and a pivot point 9 of the closure part ( 1 ).

5 shows the ramp 10 and a bead 15. The ramp 10 is higher than the bead 15. The ramp 10 thus has a greater height than the spacer bead 15.

5 shows the delivery status and the cover from the side. It can be seen that the ramp 10 (elevation) protrudes into a space (opening part 5). This free space is seen as a deepening from below. The spacer bead 15 thus acts in a delivery state with a depression 16 of the closure part 2 ( 1 or opening part 5 in 5 ) together.

On the locking part 2 is a finger-operated sliding element 14 ( 1 ) molded or bent in one piece. The sliding element 14 as a vertical to angular, in particular 20° to 80° (seen as a small trapezoidal part in 5 above the reference number 12 but bent backwards at an angle) to the closure part 2 protruding, preferably arranged essentially in the front closure part area, designed web ( DE 102018133278 A1 ). A section of the cover part 3 is offset parallel to the base of the beverage, so that it essentially forms a trough shape or trough 25 in which the closure part 2 is embedded in the closure position. Furthermore, a depression 16 ( 5 , 8th ) available, which raises the closure part 2 with the help of the spacer beads 15 so that it can tear open the flap 7 ( 7 ) facilitated
