Description

Die Erfindung bezieht sich auf einen Deckel und einen Kunststoffbehälter, wobei der Deckel mit einem nach unten stehenden Klemmrand versehen ist, welcher unter einen vorstehenden Ansatz des Behälters greift, wobei die Oberwand des Deckels weitgehend eben verläuft und bis in den Randbereich nach außen gezogen ist und wobei außerhalb der Oberwand gelegene Stapelmittel vorgesehen sind, welche beim Übereinanderstapeln mehrerer Deckel einen Abstand zwischen den benachbarten Oberwänden gewährleisten, wobei von diesem Stapelmittel mehrere vorgesehen sind, die im Abstand von einander und hinter einander angeordnet und in den nach unten stehenden Klemmrand eingeprägt sind und als radial nach innen gerichtete Einbuchtungen ausgebildet sind. Ein derartiger Behälter mit Deckel, der Gegenstand des Oberbegriffes des Anspruches 1 ist, wird in US 3 447 714 offenbart.The invention relates to a lid and a plastic container, wherein the lid is provided with a clamping edge which is at the bottom and which engages under a protruding neck of the container, the upper wall of the Lid runs largely flat and out to the edge is pulled and provided stacking means located outside the top wall which are a distance between when stacking several lids ensure the adjacent upper walls, of which stacking means several are provided that are spaced from each other and behind each other arranged and embossed in the downward clamping edge and as radially inward indentations are formed. Such a container with Lid, which is the subject of the preamble of claim 1, is disclosed in US 3,447,714.

Derartige Deckel werden maschinell mit hoher Geschwindigkeit von einem Stapel abgezogen und auf die zu verschließenden Behälter aufgesetzt. Dabei ist es sehr wichtig, daß sich die Deckel einwandfrei entstapeln und nicht gleichzeitig mehrere Deckel vom Stapel abgezogen werden. Man hat daher sehr wirksame Stufen und dergleichen als Stapelhilfen an diesen Deckeln vorgesehen, die zwar den vorgesehenen Zweck sehr gut erfüllen, die jedoch auch einen großen Anteil der Oberwand des Deckels einnehmen. Such lids are machined by a machine at high speed The stack was removed and placed on the containers to be sealed. It is it is very important that the lids are unstacked properly and not at the same time several lids are pulled off the stack. So you have very effective ones Steps and the like are provided as stacking aids on these lids, although fulfill the intended purpose very well, but also a large proportion occupy the top wall of the lid.

Der Erfindung liegt die Aufgabe zugrunde, einen Deckel der genannten Art so auszugestalten, daß eine einwandfreie Entstapelung gewährleistet ist und trotzdem kein unnötig großer Anteil der Oberwand dafür eingesetzt werden muß.The invention has for its object a cover of the type mentioned to design that a perfect denesting is guaranteed and nevertheless no unnecessarily large part of the top wall has to be used for this.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß sich die Einbuchtungen im auf den Behälter aufgesetzten Zustand des Deckels am darunterliegenden Rand bzw. dem Ansatz des Behälters abstützen.This object is achieved in that the Indentations when the lid is placed on the container on Support the edge below or the neck of the container.

Diese Einbuchtungen haben sich als sehr vorteilhafte Stapelmittel auch für übereinandergestapelte Deckel erwiesen, wobei die Oberwand des Deckels weitgehend unbeeinflußt bleibt.These indentations have also proven to be very advantageous stacking means for stacked lids proved to be the top wall of the lid remains largely unaffected.

Hierbei sind die Stapelmittel völlig unabhängig von der Oberwand des Deckels ausgebildet, so daß diese auch nicht beeinträchtigt wird.The stacking means are completely independent of the top wall of the lid trained so that this is not affected.

Eine ebenfalls sehr vorteilhafte Ausgestaltung der Erfindung liegt darin, daß die Einbuchtungen soweit nach innen gezogen sind, daß sie unterhalb der äußeren Begrenzungskante der Oberwand liegen und damit als Stapelmittel dienen.Another very advantageous embodiment of the invention is that the Indentations are drawn in so far that they are below the outer Boundary edge of the top wall and thus serve as a stacking means.

Beim Übereinanderstapeln stützte sich der Deckel am darunterliegenden Deckel sehr wirksam ab, wodurch eine saubere Entstapelung erzielt wird.When stacking one on top of the other, the lid was supported by the lid underneath very effective, which results in a clean denesting.

Dabei hat es sich als sehr günstig erwiesen, wenn erfindungsgemäß die äußere Begrenzungskante der Oberwand wenigstens geringfügig aus der Ebene der Oberwand nach oben gezogen ist.It has proven to be very favorable if the outer according to the invention Boundary edge of the top wall at least slightly from the plane of the Top wall is pulled up.

Damit ist eine definierte Gegenkante für den Klemmwulst als Stapelmittel geschaffen.This is a defined counter edge for the clamping bead as a stacking means created.

Mit 1 ist in Fig. 1 ein aus einer Kunststoffolie tiefgezogener Behälter bezeichnet, der einen Siegelrand 2 anfweist. Auf diesen Siegelrand 2 ist eine ebenfalls aus Kunststoff bestehende Verschlußfolie 3 aufgesiegelt. Der Siegelrand 2 ist an seiner Außenkante mit einem nach unten abgebogenen, umlaufenden Ansatz 4 versehen, an dem sich ein Deckel 5 verhakt. Dieser Deckel 5 beteht aus einer eben ausgebildeten Oberwand 6, an die ein nach unten abstehender Klemmrand 7 angeformt ist. Aus dem Klemmrand 7 ragt ein Klemmwulst 8 nach innen, der sich unter dem Ansatz 4 verhakt. Aus der Fläche des Klemmrandes 7 sind unterhalb der Oberwand Einbuchtungen 9 ausgeprägt, die sich im auf den Behälter aufgesetzten Zustand auf dem Siegelrand 2 abstützen. Während der Stapelung mehrerer Deckel stützen sich die Einbuchtngen 9 auf der Oberwand des jeweils darunterliegenden Deckels ab, wodurch zwischen den Oberwänden zweier benachbarter Deckel ein Abstand vorliegt, der ein gegenseitiges Festsaugen verhindert.1 in FIG. 1 denotes a container deep-drawn from a plastic film, which shows a seal edge 2. One is also out of this sealing edge 2 Plastic existing sealing film 3 sealed. The sealing edge 2 is on its outer edge with a circumferential attachment bent downwards 4 provided on which a lid 5 hooks. This cover 5 consists of a flat top wall 6 to which a clamping edge 7 projecting downwards is molded. From the clamping edge 7 a clamping bead 8 protrudes inwards caught under approach 4. From the surface of the clamping edge 7 are Underneath the top wall indentations 9, which are in the Support the container when it is in place on the sealing edge 2. During the Stacking several lids, the recesses 9 are supported on the upper wall of the respective underlying lid, whereby between the top walls there is a distance between two adjacent lids, which is mutual Stucking prevented.

Beim Ausführungsbeispiel nach Fig.4 ist ein Deckel 55 mit einem innerhalb des Klemmrandes 57 liegenden und nach innen gezogenen Klemmwulst 58 versehen, der soweit nach innen gezogen ist, daß er unterhalb der äußeren Begrenzungskante der Oberwand 56 liegt. Dieser Klemmwulst 58 besteht aus einzelnen, in einer Umfangslinie liegenden Wulstabschnitten, die aus dem Klemmrand nach innen herausgedrückt sind. Auch bei diesem Deckel 55 liegt die Oberwand 56 auf einer aufgesiegelten Verschlußfolie 3 des Behälters 1 auf und der Klemmwulst 58 stützt sich unter dem umlaufenden Ansatz 4 des Siegelrandes 2 ab. Am unteren Ende des Klemmrandes 57 ist eine nach außen gerichtete Umfangsfläche 51 angeformt, welche zwar keine Abstützfunktion hat, aber zum leichteren Erfassen des auf den Behälter aufgesetzten Deckels dient.In the exemplary embodiment according to FIG. 4, a cover 55 with an inside of the Clamping edge 57 lying and inwardly drawn clamping bead 58, which is drawn in so far that it is below the outer one Boundary edge of the top wall 56 is. This clamping bead 58 consists of individual, lying in a circumferential bead sections, which from the Are pushed out inwards. This cover 55 is also located Top wall 56 on a sealed sealing film 3 of the container 1 and the clamping bead 58 is supported under the circumferential approach 4 of the sealing edge 2 from. At the lower end of the clamping edge 57 is an outward Circumferential surface 51 formed, which has no support function, but for easier to grasp the lid placed on the container.

Beim Ausführungsbeispiel gemäß den Figuren 5 und 6 entspricht die Form des Deckels 65 weitgehend der des Beispiels nach Fig.4, jedoch ist der Umfangsrand 76 der Oberwand 66 geringfügig nach oben aus deren Ebene hochgezogen. Der Klemmwulst 68, der auch hierbei wieder aus einzelnen Wulstabschnitten besteht, stützte sich beim Übereinanderstapeln mehrerer Deckel 65 auf dem hochgezogenen Umfangsrand 76 des darunter befindlichen Deckels ab, während er im auf einen Behälter aufgesetzten Zustand unter dessen umlaufenden Ansatz 4 greift.In the embodiment according to Figures 5 and 6, the shape of the Cover 65 largely that of the example of Figure 4, but is the peripheral edge 76 of the top wall 66 is pulled up slightly from its level. Of the Clamping bead 68, which again consists of individual bead sections, leaned on top of each other when stacking several lids 65 hoisted peripheral edge 76 of the lid below, while he is placed on a container under its circumferential approach 4 takes hold.

Bei all diesen Ausführungsbeispielen ist gewährleistet, daß die Deckfläche großflächig als Displayfläche erhalten bleibt, da sie selbst keinerlei Stapelmittel enthält.In all of these embodiments it is ensured that the top surface remains large as a display area, since they themselves have no stacking means contains.
