Description

Die Erfindung betrifft einen Deckel aus Kunststoff für Behälter mit einer Vorrichtung bzw. einem System, wel­ches ein leichtes und wiederholtes Öffnen und Schlies­sen von Behältern mit Deckein ermöglicht.The invention relates to a lid made of plastic for containers with a device or a system which enables easy and repeated opening and closing of containers with a cover.

Die Anforderungen von hohen Belastungen im Transport und Verkehr mit Kunststoffverpackungen führte zu stabi­len und hochbelastbaren Packeinheiten. Hierzu werden teilweise neue und verstärkte Rohstoffe sowie dickwan­dige Behälter und Deckel eingesetzt. Von Verschlüssen wie Deckel, Kappen und Hauben wird dabei ausreichende Belastbarkeit beim Stapeln und gute Dichtigkeit gefor­dert. Das Handling in teils vollautomatischen Abfüll­betrieben und letztlich der Endverbraucher verlangen sichere und einfache Handhabung, was die Verschlußtech­nik betrifft. Hierzu sind viele Behältnisse, wie Dosen, Flaschen und dergleichen mit Abreiß- oder Öffnungs­streifen im Handel, welche ein leichtes Öffnen ermögli­chen. Nachteilig bei diesen Deckeln ist teilweise das Fehlen eines nach Abriß vorhandenen und dichten Wie­derverschlusses. Auch ist durch den Abriß und evtl. Kerben und Schwächungslinien die Belastbarkeit und Dichtigkeit eingeschränkt. Es sind Deckel mit daran angebrachten Abzugslaschen oder Stegen bekannt, bei welchen die sogenannten Stege und Laschen als Abnahme­hilfe dienen. Bei notwendigen dichten und stabilen Ver­schlüssen ist jedoch mit diesen geringen Hilfsmitteln ein leichtes Öffnen und Schließen nicht möglich.The requirements of high loads in transport and traffic with plastic packaging led to stable and heavy-duty packaging units. To this end, new and reinforced raw materials as well as thick-walled containers and lids are used. Seals such as lids, caps and hoods are required to be sufficiently resilient when stacked and to be well sealed. The handling in partly fully automatic bottling plants and ultimately the end user require safe and easy handling, as far as the closure technology is concerned. For this purpose, many containers, such as cans, bottles and the like, are commercially available with tear-off or opening strips, which enable easy opening. A disadvantage of these lids is, in part, the lack of a tight seal that is present after tearing. The tear-off and possibly notches and lines of weakness also limit the resilience and tightness. Lids with trigger tabs or webs attached to them are known, in which the so-called webs and tabs serve as removal aids. If tight and stable closures are required, however, these small tools do not allow easy opening and closing.

Aus der britischen Patentschrift GB 2091701 ist ein Containerdeckel bekannt. Dieser Deckel hat einen äus­seren Flansch, welcher durch Umklappen und Überdehnen des Kunststoffmaterials eine lösbare Verbindung mit dem Behälter bildet. Nachteilig ist die hohe auf den Flansch anzubringende Kraft mittels Finger oder auch teils nur Fingerkuppen oder zusätzlichem Werkzeug. Außerdem muß der Flansch um den gesamten Umfang des Behälters ge­löst bzw. umgeklappt werden. Dies erfordert einiges Ge­schick und ist zeitraubend. Ein Wiederverschließen ist durch die Überdehnung des Kunststoffes nur bedingt und nicht mehr zum ursprünglichen Maß hin möglich. Dichtig­keit und Belastbarkeit sind herabgesetzt.A container lid is known from British patent specification GB 2091701. This lid has an outer flange, which by folding and overstretching the plastic material a detachable connection with the Container forms. A disadvantage is the high force to be applied to the flange by means of fingers or sometimes only fingertips or additional tools. In addition, the flange must be loosened or folded around the entire circumference of the container. This requires some skill and is time consuming. Resealing is limited due to the overstretching of the plastic and is no longer possible to the original size. Tightness and resilience are reduced.

Die vorliegende Erfindung beinhaltet einen Kunststoff­deckel mit Öffnungsvorrichtung, der die oben angege­benen Nachteile vermeidet. Bei dem erfindungsgemäs­sen Ausführungsbeispiel hat der Deckel an seinem äus­seren Rand Hebel und Rasterelemente, welche als Einzel­teile, verbunden über einen Drehpunkt, wirken. Der Drehpunkt liegt in der geringen und sicheren Kraftaufwen­dung der Einzelelemente. Die Erfindung wird anhand ei­es Ausführungsbeispiels näher erläutert.The present invention includes a plastic lid with an opening device which avoids the disadvantages mentioned above. In the exemplary embodiment according to the invention, the cover has levers and grid elements on its outer edge, which act as individual parts, connected via a pivot point. The fulcrum lies in the low and safe application of force of the individual elements. The invention is explained in more detail using this embodiment.

Deckel der vorliegenden Erfindung können von Hand ma­nuell und/oder auch maschinell auf Behälter aufge­bracht werden. Beim Aufsetzen des Deckels 2 auf den Behälter 1 arretieren sich beide Teile mit dem Behäl­terrand 1a und dem Hebel 4 sowie der Schräge 3a. Der eigentliche Verschlußvorgang erfolgt durch achsialen Druck auf die Deckfläche 7 und den Rand 6. Durch die konische Schräge 3a wird der Raster 3 nach außen ge­drückt. Dies erfolgt mit geringstem Kraftaufwand, weil die Teilung 8 ein Federn nach außen ermöglicht. Bei An­lage der Deckelfläche 7 am Behälter 1 schnappen die Ra­ster 3 unter die Deckelwand 1a und der Behälter ist dicht und sicher verschlossen. Durch die rechtwinklige Anordnung des Hebels 4 zum Hebelfortsatz 5 und die ge­genüber dem Drehpunkt 5a vervielfachte Wandung des He­bels 4 und Hebelfortsatzes 5 ist eine hochbelastbare und dichte Verschlußstellung gegeben. Stöße und Drücke werden von der stabilen Winkelform abgefangen.Lids of the present invention can be applied to containers manually and / or by machine. When the lid 2 is placed on the container 1, both parts lock with the container edge 1a and the lever 4 and the bevel 3a. The actual closing process takes place by axial pressure on the top surface 7 and the edge 6. By the conical slope 3a, the grid 3 is pressed outwards. This is done with the least effort, because the division 8 allows a spring to the outside. When the cover surface 7 is in contact with the container 1, the grids 3 snap under the cover wall 1a and the container is sealed tightly and securely. Due to the right-angled arrangement of the lever 4 to the lever extension 5 and the wall of the lever 4 and lever extension 5 multiplied compared to the pivot point 5a, a highly resilient and tight locking position is provided. Shocks and pressures are absorbed by the stable angular shape.

Beim Öffnen wirkt die stabile Winkelform andererseits als feste Hebelform mit Hebel 4 und Hebelfortsatz 5. Der Drehpunkt 5a erzeugt bei Zug und/oder Druck am He­bel 4 ein Wegschwenken des Rasters 3. Damit wird die Verschlußstellung des Rasters 3 aufgegeben. Ein Abneh­men des Deckels ist locker und leicht möglich. Bei runden und ovalen Behältern wirkt die Wölbung des He­bels 4 und Deckelfortsatzes 5 in gelöster und hochge­stellter Lage als Sperre. Der hochgestellte Hebel 4 und Hebelfortsatz 5 haben beide leichte innere Zug- und/oder Druckspannungen und halten sich dadurch in der einge­nommenen Lage. Ein Wiederverschliessen ist durch leich­tes Umlegen möglich, da bei Krafteinwirkung am Hebel 4 zum Behälter hin der Raster 3, Hebel 4 und Hebelfort­satz 5 über Drehpunkt 5a umklippsen und der Raster 3 verriegelt. Bei eckigen Behältern ist dies ebenfalls möglich. Die Anordnung des Hebels 4 und Hebelfortsat­zes 5 kann an den äusseren Ecken und/oder an den Längs- oder Querseiten sein.When opened, the stable angular shape, on the other hand, acts as a fixed lever shape with lever 4 and lever extension 5. The pivot point 5a causes the grid 3 to pivot away when the lever 4 is pulled and / or pressed. The closed position of the grid 3 is thus abandoned. Removing the lid is easy and easy. In the case of round and oval containers, the curvature of the lever 4 and the lid extension 5 acts in a released and raised position as a lock. The raised lever 4 and lever extension 5 both have slight internal tensile and / or compressive stresses and thereby hold themselves in the assumed position. A reclosing is possible by slightly flipping it over, since when the force is exerted on the lever 4 towards the container, the grid 3, lever 4 and lever extension 5 clip over pivot point 5a and the grid 3 locks. This is also possible with square containers. The arrangement of the lever 4 and lever extension 5 can be on the outer corners and / or on the long or short sides.

Eine sogenannte Original- bzw. Gütesicherung ist gege­ben, wenn an den Teilungen 8 dünne Verbindungen 8a vor­ handen sind. Beim Aufdeckeln bleiben diese erhalten. Bei der Bewegung zum Öffnen am Hebel 4 und Hebelfort­satz 5 gehen die Verbindungen 8a zu Bruch. Es wird damit festgestellt, ob der Deckel gelöst und der Behälter ge­öffnet wurde.A so-called original or quality assurance is given if there are 8 thin connections 8a at the partitions are available. These are retained when the lid is opened. When moving to open the lever 4 and lever extension 5, the connections 8a break. This determines whether the lid has been removed and the container opened.

Mit dem erfindungsgemäßen Deckel aus Kunststoff mit Öffnungsvorrichtung ist ein sicheres und wiederholtes Öffnen und Verschliessen von Behältern möglich. Es sind keine aufwendigen maschinellen Vorrichtungen und zu­sätzliche Hilfsmittel erforderlich. Die erfindungsgemässe Ausführungsform ist auf alle Behältergrößen und Behälter­formen anwendbar.With the plastic lid according to the invention with opening device, a safe and repeated opening and closing of containers is possible. No complex mechanical devices or additional aids are required. The embodiment according to the invention is applicable to all container sizes and container shapes.
