Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a closure for a beverage can. [Prior Art] The flip cover is fixed to an outflow opening. The closure of the prior art has a flip cover, and a rivet of the can lid can be rotated from an open position to a closed position thereof and can be rotated. go back. SUMMARY OF THE INVENTION One object of the present invention is to improve the sealing function and operability of such a beverage can closure. For this purpose, the flap is at least partially designed in the form of a curved snap-fit piece which can be bent by a force perpendicular to the cover surface from a stable first bending state and over a pressure point. And then changing to a stable second bending state, in which the outer edge of the flip cover rests on the cover edge with a closing pressure, the cover edge defines the outflow opening, and the fastening piece can be By the second force, the second bending state is jumped back to its first bending state [Knackfrosch effect]. For example, such a higher closing pressure can be achieved in that the outer cover has a slightly larger outer diameter than the first curved state since it is less curved in the second curved state. Therefore, if the cover edge region defining the outflow opening (AUSgieB) is designed, for example, in the shape of a groove, the cover can define the cover edge of the outflow opening in the second bending state. Or 3 201043544 is referred to as micro-overlay or micro-embedded in the cover edge. To actuate the snap-fit piece, if the flip cover is attached to the rivet by a fixed central piece, the rivet is viewed by the snap-fit piece It is advantageous to extend a length beyond the rivet which is equal to an opposite action section. In another embodiment of the closure of the above type of the invention, the closure has a compression clip for opening (Aufdriicklasche, ^: press-on fishplate), the compression clip is fixed on the flip cover on the rivet of the same can lid as the flip cover, wherein the flip cover is pressed against the pressure of the clip when it is in its closed rotational position The end point (Eindrtickspitze, English: press_in tip) is held on the cover edge defining the outflow opening, and the end of the compression clip opposite the press-in tip is pulled up and supported against the can lid and engaged If a support member is pivotally connected to the end of the compression clip opposite the press-in tip, the support member is pressed after the outflow opening and after the flip cover is rotated, when the compression clip is pressed into the tip end When the opposite end is pulled high, it can be snapped down into a snap member of the can lid, so that the flip cover moved to the 2 closed position is pressed by the "pressing tip" of the compression clip to the definition On the cover edge of the "outflow opening", the flip cover can particularly securely occupy the closed rotational position. This measure also provides a positive seal with respect to the can lid when the flip cover is in the closed rotational position. The support member is based on the manufacturing technology for the reason that it should be designed integrally with the ram clip and partially punched out from the compression clip. In order to make the support member easier to bend out from the compression clip, the support member is facing away from the rivet. One end can be effectively engaged with the compression 201043544 clip in the closed position via a contour curve (Umbuglinie, English: bracing line), so that the clip is about half the length and larger than the compression clip 'Reat' of the can lid (Raste) it Leaning on the lower clip can lid, for example in the case of a rib-based compression clip leaning about half as long as (compression end by the clip viewed).

In order to make the length of the compression support member approximately one third of the length of the compression piece, all embodiments are preferably provided in the form of a compression strip or groove, at a closed position of this length to one third of the length, the pull height The degree should be about 3 0~4 5 . The yoke is provided on the rivet by a fixed clip which is partially stamped out of the material of the dust nip. For the sake of simplicity, the rivet and/or the engaging member are integrally formed from the material of the can lid. In a further feature of the invention, a guide slot is provided in the can lid, and X-turns are turned into a stamping portion on the underside. In this manner, the flip cover can be reliably changed from the open rotational position of its rear side (relative to the rear side of the outflow opening) to the closed position in front of it, so that it is easier to use.

Further, in order to make the action simpler when the outflow opening is closed, the can lid has a stopper to stop the flap in its closed rotational position. If the flip cover is applied at least partially (for example on the inside of its edge region), the sealing function can be further improved. To make the movement easier, if the outer edge of the flap has one or more flaps or similar grip areas, the flap can be easily held for rotation. 5 201043544 The selection of the materials is especially made so that the thickness of the material of ~0.3 m 丄 can be between 0.1 pens, especially about 0.224 mm, and / the thickness of the spot should be at or the compression clip Between the material and/or the millimeter, especially about q.265 mm, and the thickness of the transition should be between 0.05 and 0.15 mm.

Slightly cover the cover edge (9) [which defines the outflow opening (?)]. Comparing Fig. 1a with Fig. 1b, it can be seen that in Fig. la, the snap tab area of the flip cover (2) is placed first. The outflow opening (7) has a small gap therebetween, and after bending downward, (Fig. 1b) is pressed against the cover edge (9) (which surrounds the outflow opening) to cause a sealed state. The cover (2) uses a The fixing clip (8) is placed on the rivet (5) of the can lid (d). From the fastening piece (S), the 'fixed piece (8) is extended beyond the rivet (5) [opposite "action" Section (15)]. As can be seen from the comparison diagram lc and the figure, the fastening piece (S) can be changed from the second closed bending state to the action section (15) by applying pressure thereto. a first curved state in which the flip cover (2) can be slightly turned away to open the outflow opening (7). With the closure system of the invention of Figures 2a and 2b, such a beverage The can (the *IL outlet opening (7) is designed in the form of a "press-in opening") can also be closed more reliably. The can lid (D) [for example, it is permanently crimped to an approximately cylinder The upper end of the can body (K) is connected in a conventional manner by a pressing clip (1) via a rivet (5) [which is formed on the can lid] by means of "solid 7 201043544 fixed center month". On the same rivet (5), the rivet (5) of the head cover (9) can also be rotated, so that the can lid is in the flow two; by "the end" (the end is facing away from the opening (7)) "The moon" (I) rebelled and borrowed the Bodhisattva and the priest "--" cover (four) two two =, 7: the rotation position of the middle is turned to the closed position shown on the ^ (2) τ side - 镌 部 (i2) (Au 卵 egg g) 1 盍 (D) - (four) groove (1)) towel is guided, - straight into the stop (10) until there is - support (3) The hinged insert, the outer end of the clip can be bent from the outer end of the forced clip (1) toward the can 2 (9), and snapped into the can (_) of the can lid (D) In the snap position. At this snap position , "compression clip" (1) press the flip cover (7) with its press-in tip (6) in front of it (it is closed in rotation =) 'to make the flip cover (7) under the spring prestress of the compression piece (1) and the support piece (7) It is held in a tightly sealed manner on the cover edge (9) [the cover edge (9) defines the outflow opening (7)]. Figure 1 is indicated by a dashed line. · The flip cover (7) is partially designed in the form of a snap-fit piece (8). The hinged piece can be stabilized from the top by the flat application force of the vertical cover surface. After crossing a pressure point - entering a lower stability: bending position 'in the lower bending position' the outer edge of the turn cover (7) is pressed more strongly than the first just to the cover edge (9) [it defines the outflow Opening (7)], 俾 results in a sealed closure. Here, when the fastening piece (8) is in the initial bending position: the f-bucking action on the upper portion can be made larger than the downward bending of the fastening piece (8) in the second stable bending state. (2) 201043544 'The diameter is slightly larger than in the first bending state' In this first bending state, the fastening piece is arched upwards 'by reversing the plane perpendicular to the cover surface (2) The snap-fit area can snap the snap-fit piece (3) back to the starting position of the upper arch. After drinking the canned beverage, it can be simply resealed. Therefore, insects and dirt do not intrude into the inside of the can, and because of the reliable sealing, if the can is stored in a backpack, the remaining beverage will not flow out of the can. To reopen, push the compression clamp (1) slightly to one side until the support (3) is released from the engagement member (4) and the cover (2) is snapped back on the fastening tab (s). After it has been arched to its starting position, it can be transferred to its open rotational position. In the illustrated case, the outflow opening (7) is circular, but may also be elliptical, trapezoidal (the corners of which may be rounded) or other shapes, the form-fitting flap on the outflow opening (2) The shape is also such that the outer edge (10) of the cover (7) can have a piece or similar gripping member (which is not shown) and can easily hold the flip cover (7) for rotation.材料 The material thickness of the “compression clip” (1) may be slightly larger than the material thickness of the can lid (D), and the material thickness of the flip cover (2) is slightly smaller than the material thickness of the can lid (d).
