Abstract
Die Erfindung betrifft einen Behälter zum Aufbewahren von Lebensmitteln mit oberem waagerechten Deckel, dessen Außenrand rundum ein Dichtprofil aufweist, das bei geschlossenem Behälter am oberen Rand des Behälters anliegt, wobei der Deckel eine Öffnung mit Ventil aufweist, über die Luft aus dem geschlossenen Behälter absaugbar ist, um innerhalb des Behälters einen niedrigeren Druck (Unterdruck) zu erhalten, der geringer ist als der Atmosphärendruck, wobei ein unterer Bereich des hohlen Dichtprofils den Behälterinnenraum begrenzt und durch den im Behälter befindlichen niedrigeren Druck verformt wird, um hierdurch die am Behälterinnenrand anliegende Dichtfläche des Dichtprofils zu vergrößern.The invention relates to a container for storing food with an upper horizontal lid, the outer edge of which has a sealing profile all around which, when the container is closed, rests against the upper edge of the container, the lid having an opening with a valve through which air can be extracted from the closed container in order to obtain a lower pressure (negative pressure) within the container, which is lower than the atmospheric pressure, a lower region of the hollow sealing profile delimiting the container interior and being deformed by the lower pressure in the container, in order to thereby cause the sealing surface of the Enlarge sealing profile.
Description
Die Erfindung betrifft einen Behälter zum Aufbewahren von Lebensmitteln mit oberem waagerechten Deckel, dessen Außenrand rundum ein Dichtprofil aufweist, das bei geschlossenem Behälter am oberen Rand des Behälters anliegt, wobei der Deckel eine Öffnung mit Ventil aufweist, über die Luft aus dem geschlossenen Behälter absaugbar ist, um innerhalb des Behälters einen niedrigeren Druck (Unterdruck) zu erhalten, der geringer ist als der Atmosphärendruck.The invention relates to a container for storing food with an upper horizontal lid, the outer edge of which has a sealing profile all around which, when the container is closed, rests against the upper edge of the container, the lid having an opening with a valve via which air can be extracted from the closed container in order to maintain a lower pressure (negative pressure) within the container, which is lower than the atmospheric pressure.
Es sind Behälter zum Frischhalten von Lebensmitteln bekannt, die durch einen oberen Deckel luftdicht verschließbar sind und deren Deckel eine Öffnung mit Ventilfunktion aufweist, an der eine insbesondere von Hand betätigbare Pumpe angeschlossen wird, um im Behälterinneren einen Unterdruck zu schaffen, durch den im Behälter befindliche Lebensmittel länger haltbar sind. Solche Frischhaltebehälter werden oft „Vakuumbehälter“ genannt, obwohl nur ein Unterdruck und kein Vakuum erreichbar ist.Containers for keeping food fresh are known, which can be closed airtight by an upper lid and the lid of which has an opening with a valve function, to which a pump, which can be actuated in particular by hand, is connected in order to create a negative pressure in the interior of the container, due to the pressure in the container Foods have a longer shelf life. Such fresh-keeping containers are often called “vacuum containers”, although only a vacuum and no vacuum can be reached.
Bei diesen bekannten Frischhaltebehältern befindet sich am Rand des Behälterdeckels oft ein Dichtprofil, das an der Innenfläche des oberen Randes der Behälterwand anliegt. Hierbei hat sich gezeigt, dass eine ausreichende Dichtheit über längere Zeit oft nicht erreicht wird. Dieses Problem tritt besonders dann auf, wenn der Frischhaltedeckel auf verschiedene Behälter mit Behälterwänden aus unterschiedlichen Materialien Verwendung finden soll. So kann ein bekannter Deckel z. B. auf einem Behälter mit Wänden aus Kunststoff ausreichend abdichten, aber derselbe Deckel ist auf Behälter mit Wänden aus Keramik oder Glas nicht verwendbar.In these known fresh food containers, there is often a sealing profile at the edge of the container lid, which lies against the inner surface of the upper edge of the container wall. It has been shown that sufficient tightness is often not achieved over a long period of time. This problem occurs particularly when the fresh-keeping lid is to be used on different containers with container walls made of different materials. So a known cover z. B. sufficiently seal on a container with walls made of plastic, but the same lid cannot be used on containers with walls made of ceramic or glass.
Aufgabe der Erfindung ist es, einen Behälter der eingangs genannten Art so zu verbessern, dass der Deckel mit seinem Rand eine hohe Dichtheit über längere Zeit erreicht insbesondere bei Behälterwänden aus unterschiedlichen Materialien.The object of the invention is to improve a container of the type mentioned in such a way that the lid with its edge achieves a high level of tightness over a long period of time, particularly in the case of container walls made of different materials.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass ein unterer Bereich des hohlen Dichtprofils den Behälterinnenraum begrenzt und durch den im Behälter befindlichen niedrigeren Druck verformt wird, um hierdurch die am Behälterinnenrand anliegende Dichtfläche des Dichtprofils zu vergrößern.This object is achieved according to the invention in that a lower region of the hollow sealing profile delimits the interior of the container and is deformed by the lower pressure in the container, in order to thereby enlarge the sealing surface of the sealing profile lying against the inner edge of the container.
Somit bewirkt der im Behälterinneren befindliche Unterdruck eine Veränderung der Querschnittsform des Dichtprofils in einer solch positiven Weise, dass die Profildichtfläche, die am Behälterinnenrand anliegt, vergrößert ist und hierbei noch kräftiger die Innenwand kontaktiert. Hierdurch erreicht das Dichtprofil an Behälterwänden einen ausreichend dichten Halt auch dann, wenn die Behälterwand aus den unterschiedlichsten Materialien besteht. Vorteilhafterweise wird in einfacher Weise ein Ausgleich möglicher Fertigungstoleranzen erzielt. Außerdem erhält der Benutzer durch die Verformung des Dichtprofils vorteilhafterweise einen visuellen Eindruck über den im Behälter befindlichen (nicht sichtbaren) Unterdruck.Thus, the negative pressure inside the container causes a change in the cross-sectional shape of the sealing profile in such a positive manner that the profile sealing surface, which rests on the inside edge of the container, is enlarged and thereby contacts the inner wall even more vigorously. As a result, the sealing profile on the container walls achieves a sufficiently tight hold even when the container wall is made of a wide variety of materials. Advantageously, a compensation of possible manufacturing tolerances is achieved. In addition, the deformation of the sealing profile advantageously gives the user a visual impression of the (not visible) negative pressure in the container.
Vorzugsweise wird vorgeschlagen, dass das Dichtprofil ein geschlossenes Hohlprofil ist, dessen Außenumfang durch die Verformung des unteren Bereichs des Dichtprofils sich vergrößert.It is preferably proposed that the sealing profile is a closed hollow profile, the outer circumference of which increases due to the deformation of the lower region of the sealing profile.
Eine besonders dichte und sichere Anlage des Dichtprofils an der Behälterinnenwand wird dann erreicht, wenn die Wandstärke des unteren abdichtenden Bereichs des Dichtprofils dünner ausgestaltet ist als die des oberen Bereichs. Hierzu wird auch vorgeschlagen, dass das Dichtprofil im unteren abdichtenden Bereich Noppen, Wülste oder Ausformungen aufweist, die in Längsrichtung des Dichtprofils verlaufen.A particularly tight and secure contact of the sealing profile on the inner wall of the container is achieved if the wall thickness of the lower sealing area of the sealing profile is made thinner than that of the upper area. For this purpose, it is also proposed that the sealing profile in the lower sealing area has knobs, beads or formations which run in the longitudinal direction of the sealing profile.
Eine hohe Verformbarkeit des hohlen Dichtprofils wird verbessert, wenn in der Außenwand des geschlossenen Dichtprofils mindestens eine Öffnung oder eine Membran ist, durch die der Dichtungsinnendruck mit dem Atmosphärendruck ausgeglichen wird.A high deformability of the hollow sealing profile is improved if there is at least one opening or a membrane in the outer wall of the closed sealing profile, through which the internal seal pressure is balanced with the atmospheric pressure.
Alternativ zu einem geschlossenen Hohlprofil wird vorgeschlagen, dass das Dichtprofil ein nach oben offenes Profil ist, dessen Innenraum mit der Atmosphäre verbunden ist. Auch kann der verformbare untere Bereich des Dichtprofils konvex oder konkav oder unrund insbesondere eckig geformt sein.As an alternative to a closed hollow profile, it is proposed that the sealing profile is a profile which is open at the top and whose interior is connected to the atmosphere. The deformable lower region of the sealing profile can also have a convex or concave or non-circular shape, in particular an angular shape.
Eine Verbesserung der Abdichtfunktion wird erreicht, wenn der verformbare untere Bereich des Dichtprofils über eine Sprungfunktion zwei stabile Zustände einnimmt, wobei durch den saugenden Unterdruck im Behälterinneren der verformbare untere Bereich nach unten und/oder zur Seite springt. Auch kann das Dichtprofil ein durch einen Extruder hergestelltes abgelängtes Endlosprofil sein.An improvement in the sealing function is achieved if the deformable lower region of the sealing profile assumes two stable states via a snap function, the deformable lower region jumping down and / or to the side as a result of the suction vacuum inside the container. The sealing profile can also be an endless profile cut to length by an extruder.
