Definitions

• the invention relates to the lid of a container, in particular a beverage can, with at least one outlet opening penetrating the lid, which is reclosable via at least one closure element, wherein the at least one closure element is arranged on the underside of the lid, and the at least one closure element via a on the Upper side of the lid arranged actuating element from a closed position in which the at least one outlet opening is closed, in an open position in which the outlet opening is at least partially exposed, is movable, and the at least one closure element, a first sealing means for sealing the at least one outlet opening has against the underside of the lid.
• Containers of the type described above are produced, for example, as resealable beverage cans.
• an outlet opening is provided in the lid mirror, which, like the rest of the metal can, is usually made of aluminum or tinplate.
• This opening is closed by a closure means which rests inside the can on the lid mirror.
• This closure means is moved by an externally operable actuator, for example by means of a flap or a slider, from a closed position to an open position, whereby the outlet opening is exposed to empty the can and is again tightly closed after the first opening.
• a beverage can for example, the AT 507 950 A1 of the applicant are taken.
• a major problem with resealable beverage cans is the required low germ load.
• remnants of the contents often remain in the region of the pouring opening, which after reclosing represent a source of contamination and thus the occurrence of mold and the like.
• the actuating element has at least a second sealant that seals the at least one outlet opening against the top of the lid.
• the combination of two sealing means causes the first sealing means, which is arranged on the closure element on the inside, a leakage of the Beverage contents prevented via the outlet opening, while the second sealant seals the outlet opening against the environment, thus preventing the entry of germs in the production cycle, especially during filling, optionally during a post-treatment and during transport to the customer to the outlet opening.
• At least one further opening penetrating the lid is provided, which is likewise sealed against the top side of the lid via the second sealing means.
• this second opening penetrating the lid is a pressure equalization opening, which is first exposed upon actuation of the actuating element for opening the container to drain the usually prevailing in the beverage can overpressure when it is filled with a carbonated beverage, then to the Expose outlet opening itself.
• this second opening is susceptible to contamination, so that in this embodiment of the invention, this pressure equalization opening on the second sealing means, which is arranged on the actuating element, is sealed. Likewise, however, it may be provided that this opening is protected against contamination by the environment via a further, third sealant.
• the second and / or third sealing means is designed as a sealing lip and / or sealing edge.
• the sealing lip or sealing edge with the lid mirror includes an angle not equal to 90 degrees, which causes an improved seal against the environment.
• the second sealing means is formed integrally with the actuating means. This facilitates the assembly of the closure device on the lid during manufacture and reduces misalignments and, consequently, problems with the sealing properties of the second sealant.
• the actuating element is usually made of a rigid plastic material, while the sealing means must have flexible properties for the seal, it is particularly preferred that the actuating element is made as a two-component injection molded part to allow the one-piece production with the sealing means according to the invention.
• the actuating element has at least one joint over which the second sealing means extends.
• the opening of the container and thus the exposure of the outlet opening is facilitated by the fact that the actuator Has joint that facilitates lifting and / or moving the actuator.
• the arrangement of the second sealing means via the joint ensures that the outlet opening and optionally the ventilation opening are securely sealed when the container is resealed.
• the secure sealing of the opening located in the cover are ensured, in particular, when the second sealing means extends substantially parallel to the outer edge of the actuating element.
• At least partially at least one spacer element is arranged parallel to the second sealing means.
• the sealant is subject to forces due to the internal pressure and the resulting deformation of the container lid as well as opening and reclosing the container, which accelerate the wear of the sealant.
• the spacer which is preferably designed as an outer edge, now has the task of intercepting these forces in order to achieve a mechanical decoupling and thus to reduce the action of force on the sealant.
• the second sealing means has a first region, which is located in the open position of the closure element in the region of the outlet opening, and in that this first region has only one sealing bead. It is often unavoidable that the sealing element during the opening movement in a first area sweeps over the edge of the pouring opening. A sealing lip can be damaged or destroyed during this or during a subsequent closing movement. Therefore, it is particularly advantageous if the sealing element is robust in these areas and, for example, has only one sealing bead. In practice, this is done so that unite in the transition to this first area sealing lip and sealing bead. Thus, a partially slightly deteriorated seal is accepted in order to avoid problems with opening and reclosing.

• the lid mirror 101 has a pouring opening 103, which in the closed position of the actuating element 110 is closed by a closure element 120 arranged below the lid mirror 101.
• This closure element 120 has a first sealing means 121, which seals the container contents against the underside of the lid mirror 101 and thus prevents leakage of the re-sealed beverage can.
• an opening is further arranged, which continues in the closure element 120 as a pressure equalization opening 122 into which a pin 1 12 of the fixing element 1 10a engages when the container is closed.
• actuating element 1 10 is shown in a sectional view, wherein on the underside of the actuating element 1 10 a second sealing means 130 is arranged, the Hzkante substantially along the outer edge of the actuating element 1 10 extends (Fig. 4).
• a third sealing means 131 is arranged on the fixing element 1 10a and in this case surrounds the pin 1 12.
• This third sealing means 131 is formed as a double seal, which comprises a sealing lip 131 a and a sealing bead 131 b, which is formed in the manner of a 0_ring ,
• the sealing bead 131 b serves not only for sealing, but also as a spacer element, which protects the sealing lip against excessive load in case of improper opening or closing.
• the sealing lip 131 a intersects the support plane E1 of the actuating element 1 10 on the lid mirror 101 at an angle of about 40 ° to 50 °.
• the second and the third sealing means 130, 131 are made in this embodiment of the invention of a single material, namely that of the actuating element 1 10.
• the sealing lip 131 a is designed to be particularly slim in order to achieve sufficient flexibility and thus sealing. 5 further embodiments of the third sealant 131 according to the invention are shown, wherein it should be noted that the following statements apply analogously to the second sealant 130.

• Fig. 5a provides that only the sealing lip 131 a is made of a soft material, and in Fig. 5b, a variant is shown, which provides an actuator 1 10 with sealing means 131 of a single material, which offers corresponding cost advantages , In this case, the formation of the sealing lip 131 a is essential to ensure adequate sealing.
• the lid according to the invention is not limited to the embodiment described above.
• the second sealing means may be arranged in different ways on the actuating element, and have different cross-sections. It is essential that the outlet opening in the lid mirror and an optionally existing pressure equalization opening are sealed by suitable sealing means on the actuating element against the environment.
