Abstract

A tear-off closure arranged in the lid (1', 12, 29, 38, 42, 47, 54, 56, 59, 68) of a beverage can (1, 11, 21, 67) has a closure tab (3, 13, 31, 40, 44, 51, 55, 58, 61, 71) prepunched in the lid and surrounded by a rated braking line (30, 39, 43, 48, 62, 69) which creates a pouring opening (2, 28) when the closure tab is pressed in or torn off by means of a tearing tab (4, 23, 60). In order to prevent insects, such as wasps or bees, from entering the opaque beverage can (1, 11, 21, 67), as well as to prevent foreign bodies from eventually coming out of the beverage can, an additional closure element (7, 16, 26, 33, 45, 51, 55, 58, 66, 70) is linked to the lid (1', 12, 29, 38, 42, 47, 54, 56, 59, 68), besides the closure tab (3, 13, 31, 40, 44, 51, 55, 58, 61, 71) and possibly the tearing tab (4, 23, 60), and partially covers the pouring opening (2, 28), allowing as before the beverage to be drunk through the largest open opening, but preventing insects from entering. The closure element may be fixed or movable between its open position and a covering position.

Description

 i Zipper inside a beverage container

³ Technical field:

⁴ The invention relates to a zipper inside a beverage

⁵ container according to the preamble of claim 1.

6

⁷ State of the art:

⁸ Such zippers are preferably in can containers

⁹ tin cans, widely used; that for beer, sweet juices and soft drinks

¹⁰ Use. After opening the closure and forming the training

¹¹ pouring opening by pressing in a pre-punched tab inside the lid of the

¹² beverage containers, the sweet scent always attracts insects, especially outdoors

¹³ , which goes unnoticed through the open pouring opening into the interior of the beverage container

^{1 can} reach, but where they remain invisible to the user. The can as an un

¹⁵ transparent containers do not allow the consumer to drink from a can

¹⁶ direct eye contact with the drink. An unnoticed insect

¹⁷ , however, can be an extremely dangerous situation if you continue to drink

Already ¹⁸ alarming newspaper reports that report users of such beverage cans w that were stung while drinking wasps or bees. Such

²⁰ stitches in the mouth or neck area lead to painful and dangerous

²¹ swellings that require immediate medical attention. With a strong arrival

²² Swelling in the stir area can also cause death from suffocation if

^{23 there is} no quick medical help on the spot. Similarly, deaths from insect

² stings occur if the insect's sting in the affected person has an anaphylactic

²⁵ see shock that is not treated in time. The open ⁶ pouring opening of a beverage container is therefore a considerable one when drinking

^{27 represents a} danger that applies particularly to children.

28

»Technical task:

³⁰ The invention is therefore based on the object, a zipper at the beginning

³¹ to create the type mentioned, by means of which the pouring opening of a beverage

³ box, preferably tin or plastic box, after tearing and forming the

³³ pouring opening can at least partially be closed again ¹ remains to prevent dangerous insects from entering the invisible interior of the

² beverage containers to prevent. Furthermore, the danger should be countered

³ that foreign bodies are swallowed by the person drinking from the container

* enters the beverage during filling, container manufacturing and sealing

* could be.

⁷ Presentation of the invention and its advantages:

⁸ The solution to the problem is, according to the invention, that with the lid, in addition to the 'closure flap and possibly the tear-open flap, another closure

¹⁰ element is connected, which for at least partially covering the pouring

¹¹ opening is capable. The closure element can from a release position for

¹² the complete opening of the pouring opening in a cover position of the same can be moved.

¹³ stigt. The closure element is preferably a plate of slightly more than that

¹⁴ size of the pouring opening and has sieve-like openings. In a further preferred design, the closure element is an inside underneath the pouring

¹⁶ opening arranged saber-shaped basket, within which the locking tab after the

¹⁷ Tear open at an angle, or one inside with the

¹⁸ outer pull tab pivotally arranged plate.

19

²⁰ The invention has the salient advantage that by the zipper

²¹ in the case of a beverage container, preferably a tin or plastic can, the drinking

²² opening after it has been formed by tearing the tab during the

²³ Drinking remains closed as far as possible or closed again after drinking

²⁴ may be that dangerous insects enter the interior of the

²⁵ beverage container is prevented and thus the risk of injury when drinking

²⁶ a person in the mouth area from dangerous insects such as bees or wasps

^{27 is} closed. Another advantage of the zipper is that

²⁸ foreign objects in the liquid in the beverage container cannot be swallowed by the drinker ∞.

30

³¹ The closure element according to the invention does not interfere with drinking, in particular if ² it - in the form of an integral closure element and tear-open tab or closure element and ³ closure tab - is designed as a tear-open and closure tab or ins Inside of the beverage container is placed. In particular, it is possible to implement the invention on the existing zippers with the few changes. Further refinements of the invention are characterized in the subclaims.

Brief description of the drawing, in which: FIG. 1 shows a first exemplary embodiment of a zipper in plan view of a lid of a beverage container with a closure element in the cover position, which is shown in FIG. 2 in its release position after the pouring opening has been torn open, FIG. 3 shows a zipper with the Tear tab separate closure element which is rotatably arranged on the outside of the lid Figure 4 shows a cross section through a beverage container with a plan view from the inside of the lid, which has a closure element separate from the tear tab, which is fixed on the inside of the lid with the outer tear tab 5 is a snap fastener with a sieve-shaped closure element fixedly arranged above the closure flap outside the beverage container. FIG. 6 shows the closure element of FIG. 5. FIG. 7 shows the closure flap and the tear flap 5, FIG. 8, a further closure element with a slit-shaped pouring opening, FIG. 9, a beverage container with a closure element according to FIG. 8, which is firmly attached to the outside of the lid above the closure flap; FIG. 10; the design of the closure flap in FIG. 9; Tear-open and closure flap in the open position of the pouring opening Figure 12 the tear-open closure of Figure 1 1 in the closed position of the pouring opening Figure 13 a tear-open closure with a rotatable tear-open and closure flap Figure 15 is a zipper, the pouring opening of which after tearing the closure tab consists of four narrow, elongated slots, Figure 16 is a similar zipper as in Figure 15, the pouring opening i is crescent-shaped with two narrow slots

⁸ ways of carrying out the invention: FIG. 1 shows a lid 1 'of a ¹⁰ known beverage container 1 extending perpendicular to the plane of the drawing. According to FIG. 2, a pouring opening 2' is predetermined in the lid 1 'in that one, in FIG pressed, locking

¹² tab 3 is pre-punched in the lid 1 'to form a predetermined breaking line. To the

¹³ Tear open the locking tab 3 with a tear tab 4 or - another hand - ⁴ to tear open. The tear-open tab 4 is connected to the lid 1 'by a ⁵ rivet 5, which is preferably a hollow rivet ⁶ punched into the lid wall and allows the pull-tab 4 to pivot and rotate; the rivet ⁷ 5 thus serves as a pivot axis in a direction perpendicular to cover plane and plane as a knuckle DRE ⁸ in the ceiling plane. 9 ⁰ In this way, the pull-tab 4 after the peeling of the closure flap 3 of ^{Figure 1} the lid 1 'to form the pouring opening 2 in the position of Figure 1 be bought pivots. To this end, the tear-open tab 4 can have a pull ring 6 in a known manner, on which a closure element 7 is provided, which is preferably sieve-shaped with such small sieve openings 8 that insects cannot penetrate into the inside of the beverage container through the sieve openings 8 . At the same time, it represents an important protection against possible foreign bodies that can enter the container during container manufacture or filling. It may be advantageous if the screen-like closure element 7 is arranged below the central plane of the tear tab 4. On the one hand, enough gripping surface is created on the pull ring 6 ^ if the closure element 7 is arranged in the opening thereof and not in a separate opening of the tear-open tab 4, on the other hand, drinking through the sieve is possible as before. ¹ Figure 3 shows a zipper, in the sieve 7 and tear tab 4 as a separate

² parts are each pivotable about the rivet 5. In the upper half of Figure 3 is the

³ position of the sieve 7 indicated by dash-dotted lines, which it after the opening of the pouring

⁴ opening 2 and before it swings over. The screen 7 is at least equal to * the closure flap 3, preferably greater than, to provide a safe covering of the pouring opening ^β 2 to ensure. After tearing the screen 7 in the

^{7 shown in the} lower half of FIG. 3 when covering is desired.

⁸ The sieve can also be integrated in a disc corresponding to the inner surface of the lid

⁹ and be easily rotatable around the rivet until the sieve covers the pouring opening.

10

"In order to ensure tight abutment of the covering closure element 7, this" flattening 10 having the front edge, which upon closure under a ¹³ retaining means 9, such as a nose is running, which is au secured the lid 1 '.

14

"The pull tab of Figure 3 can also be integrally formed as with the closure element" angle-stamping be formed, for example, the "are including an angle of 90 degrees, so ¹⁷ that the closure element is pivoted upon rotation of the pull-tab, advantageously below the pull-tab .

19

²⁰ While 7 sieve openings are not essential with a movable closure element

^{21 are} required because a fully covering closure element for drinking is easy again

²² may be removed, a screen does not need in the manner shown so far have hole ^3-porous. It is sufficient if the pores are small enough to prevent ⁴ insects from entering. Furthermore, the closure element and the tear-open tab ^{5 can be} identical and, for example, according to FIGS. 1 and 2, consist of a stamped part. 6 ⁷ An embodiment of a rotatable closure element 60, in which the tear-open tab and ⁸ lock element are identical and, for example, produced as a common stamped part, consists, according to FIG. 13, of a material cross 66 or star or a rosette ⁰ within the pull ring of the tear-open tab 60 figures 11, 12, a ¹ a lid 42 pivotable about a rivet 22 and rotatable tearing and closure element 45 ² with screen openings 46, which can be rotated by depression of the closure flap 44 over the pouring opening ³ 43rd Even when the ¹ pouring opening and closing element 45, drinking is possible,

2 without having to turn it back each time.

⁴ Figure 4 shows a design in which the inside of the beverage container 11 on the

⁵ cover 12 a shield-like closure element 16 with sieve openings 19 is arranged,

⁶ which is arranged together with the outside by means of a separate rivet 14

⁷ (dotted drawing) pull tab 23 is fixed but rotatably connected,

^{8 for} which the rivet 14 can have a square cross section. The

⁹ closure element 16 is shaped in the region of the rivet 14 so that when erecting and

¹⁰ pivoting the tear tab 23 in a plane perpendicular to the lid 12

¹¹ closure tab 13 past the closure element 16 can be pressed inwards;

¹² , it is preferably in the area of the rivets 14 on which the locking tab 13

¹³ narrow side running in the form of a stem 20 or has one

¹⁴ recess. If the sealing tab 13 is pressed inwards and the pouring spout

¹⁵ opening 28 has arisen, the tear tab 23 can be rotated on the outside of the rivet 14 in the w plane of the cover while taking the inside closure element 16 with it.

¹⁷ until it covers the pouring opening 28 from the inside. The closure element 16 is

¹⁸ preferably curved like the cover 12. The rivet 14 by the

¹⁹ Cover 12 protrudes, must be riveted gas-tight within cover 72.
