Definitions
- the invention relates to a two-part packaging made of plastic, in particular for biscuits, consisting of a bottom receiving the packaging material, which has a lower base and a higher, outwardly directed, substantially peripheral edge, and a hood-shaped upper part with a the edge of Lower part overlapping and seated in the closed position edge with locally inwardly projecting locking lugs to form edge clip connections.
- Two-part plastic packaging of the type mentioned are known in many forms and for a wide variety of packaging goods. They have the advantage that their upper part and lower part can each be produced inexpensively as a simply shaped individual item and stored in a space-saving manner.
- the upper part and lower part have to be recorded and brought together to the other, which is done by hand, with the aim is to place the upper part evenly on the upper part, then close it with pressure far enough to the lower part until the locking lugs form the upper part with the edge of the lower part clip connections.
- the items of known packaging with the hitherto usual material thicknesses can also be closed only with relatively high contact pressure, which also can not easily apply evenly to all provided clip connections, so that the closing process is not without problems and a special attention to be directed got to.
- the clip connections are often activated one after the other, with the connections already made to keep their shape, while elsewhere top and bottom must first be approximated and compressed, which requires at least partial deformations.
- the dilemma shows the dilemma that the desired and required in one place form stiffness elsewhere is detrimental and vice versa.
- the basic idea of the invention is an optimal positioning of lower part and upper part, before they are joined together via the clip connections.
- the positioning is simplified and improved such that a loose lowering or settling of the upper part above the lower part is already sufficient for the correct and accurate assignment. In this case, no additional pressure needs to be exercised, but rather it is possible that the upper part already reaches the desired closed position as a result of its own weight and thus acts quasi self-centering.
- a packer does not have to act on the positioning by hand, whereby the positioning process is significantly disconnected from the closing process. It is also not necessary that To increase dead weight. On the contrary, it has even been shown that the material thickness can be chosen quite lower than before.
- sliding and centering surfaces are provided in the corner areas in a package with angular plan.
- locking lugs are arranged in the region of the sliding and centering surfaces.
- a tab-shaped extension joins as a handle on the edge of the lower part.
- edge of the upper part in the region of the handle is widened in about its length, wherein a recess is provided directly above the handle of the lower part.
- the upper part is designed as a deep-drawn part of transparent plastic.
- the lower part is more compliant with its edge than the upper part with its locking lugs.
- the edge of the lower part is formed stepwise in cross section with at least one step.
- the step-shaped edge closes outwards with a narrow, horizontal edge strip.
- lower part and upper part are dimensioned so that after the loose fitting of the upper part on the lower part, the locking lugs of the upper part are supported on the horizontal edge strip of the lower part.
- the locking lugs are essentially formed of two slopes, of which the top projecting from top to bottom and the bottom from bottom to top inside the shell.
- the last-mentioned embodiments in which the edge of the lower part is formed in stages, are characterized by the fact that the respective packaging can be securely closed even with little contact pressure.
- the stage design causes the upper part can lower without major resistance to the lower part to the closed position, with the last take over the locking lugs of the upper centering function.
- the locking lugs need to push on the narrow edge strip on the lower part, whereupon they dodge downwards and inwards and take their old position again after lowering the locking lugs.
- edge strip can dodge down more easily, it is not so easy to deform upwards, because a move up against the gradual training, ie their resistance to deformation. Thus, despite a low contact pressure for closing a high extraction force for opening may be required. This makes it possible to make a packaging according to the invention safe and durable.
- Fig. 1 to 3 has the lower part 1 of a package according to the invention a, seen in plan view, approximately rectangular base body with two square recesses 2 for receiving a packaged goods (not shown). These may be, for example, two loose biscuits, for which then the packaging is used as primary packaging.
- the depressions 2 close on the bottom side with a base 3 from.
- the lower part 1 also has a peripheral edge 4, which extends above the base 3.
- the edge 4 is here stepped and terminates outwards with a narrow horizontal edge strip 4a.

Abstract
Description
Die Erfindung betrifft eine zweiteilige Verpackung aus Kunststoff, insbesondere für Gebäckstücke, bestehend aus einem das Verpackungsgut aufnehmenden Unterteil, welches über eine untere Standfläche und einen höher liegenden, nach außen gerichteten, im Wesentlichen umlaufenden Rand verfügt, sowie einem haubenförmigen Oberteil mit einem den Rand des Unterteils übergreifenden und in Schließposition darauf aufsitzenden Rand mit stellenweise nach innen vorstehenden Rastnasen zur Bildung von randseitigen Clipverbindungen.The invention relates to a two-part packaging made of plastic, in particular for biscuits, consisting of a bottom receiving the packaging material, which has a lower base and a higher, outwardly directed, substantially peripheral edge, and a hood-shaped upper part with a the edge of Lower part overlapping and seated in the closed position edge with locally inwardly projecting locking lugs to form edge clip connections.
Zweiteilige Verpackungen aus Kunststoff der genannten Art sind in vielfältiger Form und für die unterschiedlichsten Verpackungsgüter bekannt. Sie besitzen den Vorteil, dass ihr Oberteil und Unterteil jeweils als einfach geformtes Einzelteil preiswert hergestellt und platzsparend bevorratet werden können. Schwierigkeiten bereitet aber mitunter das passgenaue Zusammenführen und einwandfreie Verschließen von Unterteil und Oberteil. Dazu müssen nämlich Oberteil und Unterteil zum einen erfasst und zum anderen zusammengebracht werden, was in der Regel von Hand erfolgt, wobei angestrebt wird, das Oberteil gleichmäßig auf dem Oberteil zu platzieren, um es danach mit Druck soweit an das Unterteil anzunähern, bis die Rastnasen des Oberteils mit dem Rand des Unterteils Clipverbindungen bilden.Two-part plastic packaging of the type mentioned are known in many forms and for a wide variety of packaging goods. They have the advantage that their upper part and lower part can each be produced inexpensively as a simply shaped individual item and stored in a space-saving manner. However, there are sometimes difficulties in matching and merging Perfect closing of lower part and upper part. For this purpose, namely, the upper part and lower part have to be recorded and brought together to the other, which is done by hand, with the aim is to place the upper part evenly on the upper part, then close it with pressure far enough to the lower part until the locking lugs form the upper part with the edge of the lower part clip connections.
Bereits das Erfassen und Umsetzen der Einzelteile ist von Deformationen begleitet, die man durch eine gewisse Wand- oder Materialstärke einzuschränken versucht. Kommt es beim Zusammensetzen der Einzelteile nicht direkt zu einem passgenauen Sitz, sind Korrekturen erforderlich, welche meist unter einem gewissen Anpressdruck der Einzelteile vorgenommen werden, wodurch es auch zu einem Verhaken und noch stärkeren Deformationen kommen kann. Mitunter helfen nur mehrere Justierversuche weiter.Already the detection and implementation of the individual parts is accompanied by deformations that one tries to limit by a certain wall or material thickness. If it comes to the assembly of items not directly to a custom fit, corrections are required, which are usually made under a certain contact pressure of the items, which can also lead to snagging and even stronger deformations. Sometimes only several adjustment attempts help.
Schließlich lassen sich die Einzelteile bekannter Verpackungen mit den bis jetzt üblichen Materialstärken auch nur mit relativ hohem Anpressdruck verschließen, welcher sich zudem nicht so leicht gleichmäßig auf alle vorgesehenen Clipverbindungen aufbringen lässt, so dass auch der Verschließvorgang nicht unproblematisch ist und ein besonderes Augenmerk darauf gerichtet werden muss.Finally, the items of known packaging with the hitherto usual material thicknesses can also be closed only with relatively high contact pressure, which also can not easily apply evenly to all provided clip connections, so that the closing process is not without problems and a special attention to be directed got to.
So werden in der Praxis die Clipverbindungen oft nacheinander aktiviert, wobei die bereits zustande gekommenen Verbindungen ihre Form halten sollen, während an anderer Stelle Oberteil und Unterteil erst noch einander angenähert und zusammengedrückt werden müssen, was zumindest partielle Verformungen verlangt. Hier zeigt sich dann das Dilemma, dass die an einer Stelle gewünschte und benötige Formsteifigkeit an anderer Stelle abträglich ist und umgekehrt.Thus, in practice, the clip connections are often activated one after the other, with the connections already made to keep their shape, while elsewhere top and bottom must first be approximated and compressed, which requires at least partial deformations. Here then shows the dilemma that the desired and required in one place form stiffness elsewhere is detrimental and vice versa.
Somit hängt das Zusammenfügen und Verschließen von Oberteil und Unterteil von verschiedenen Einflussgrößen ab, die zu einem Teil in der Verpackung selbst begründet sind, im Übrigen aber auch in nicht unbeträchtlichem Maße in der Geschicklichkeit und Übung der Menschen, die den jeweiligen Verpackungsvorgang erledigen sollen. Da sich mit steigendem Wohlstand ein enormer Bedarf an Verpackungen ergeben hat, welcher sogar noch weiter anwachsen dürfte, besteht ein großen Bedürfnis, Verpackungen zu schaffen, welche sich möglichst unproblematisch handhaben lassen und eine ausreichende Störungsfreiheit und Prozesssicherheit beinhalten, um notwendige Behandlungsschritte auch maschinell und letztlich automatisch erledigen zu können.Thus, the joining and closing of upper part and lower part of various influencing factors depends, which are due to a part in the package itself, but otherwise in not inconsiderable degree in the skill and practice of the people who are supposed to handle the particular packaging process. Since there has been an enormous demand for packaging with increasing prosperity, which is likely to increase even further, there is a great need to create packaging that can be handled as easily as possible and include sufficient freedom from malfunctions and process reliability to machine and ultimately necessary treatment steps to be able to do it automatically.
Hier setzt die Erfindung an. Sie will eine Verpackung der eingangs genannten Art dahingehend verbessern, dass sie sich schnell, leicht und sicher aus Oberteil und Unterteil passgenau zusammensetzen wie auch verschließen lässt; dabei soll die Verpackung einfach und preiswert herstellbar sein.This is where the invention starts. She wants to improve a package of the type mentioned in that they quickly, easily and safely from the top and bottom fit together as well as can be closed; while the packaging should be easy and inexpensive to produce.
Gelöst wird diese komplexe Aufgabe nach dem Vorschlag der Erfindung mit den kennzeichnenden Merkmalen von Anspruch 1. Vorteilhafte Weiterbildungen geben die Unteransprüche 2 bis 11 an.This complex object is achieved according to the proposal of the invention with the characterizing features of
Wie ersichtlich, gilt der Grundgedanke der Erfindung einer optimalen Positionierung von Unterteil und Oberteil, bevor diese über die Clipverbindungen zusammengeschlossen werden. Das Positionieren vereinfacht und verbessert sich derart, dass ein loses Ablassen oder Absetzen des Oberteils über dem Unterteil bereits für die richtige und genaue Zuordnung ausreicht. Dabei braucht kein zusätzlicher Druck ausgeübt zu werden, vielmehr ist es möglich, dass das Oberteil bereits infolge seines Eigengewichts in die gewünschte Schließposition gelangt und damit quasi selbstzentrierend wirkt.As can be seen, the basic idea of the invention is an optimal positioning of lower part and upper part, before they are joined together via the clip connections. The positioning is simplified and improved such that a loose lowering or settling of the upper part above the lower part is already sufficient for the correct and accurate assignment. In this case, no additional pressure needs to be exercised, but rather it is possible that the upper part already reaches the desired closed position as a result of its own weight and thus acts quasi self-centering.
Anders als bisher braucht also ein Verpacker nicht von Hand auf die Positionierung einzuwirken, wodurch der Positioniervorgang deutlich vom Verschließvorgang abgekoppelt wird. Es ist auch nicht erforderlich, das Eigengewicht zu erhöhen. Ganz im Gegenteil hat sich sogar gezeigt, dass die Materialstärke durchaus geringer als bisher gewählt werden kann.Unlike before, therefore, a packer does not have to act on the positioning by hand, whereby the positioning process is significantly disconnected from the closing process. It is also not necessary that To increase dead weight. On the contrary, it has even been shown that the material thickness can be chosen quite lower than before.
Infolge einer gleichmäßigen Positionierung wird auch der Schließvorgang erheblich begünstigt. Es reicht nämlich jetzt ein geringerer Druck aus, die Clipverbindungen herzustellen. Auch kann ein geringerer Druck selbst bei einer geringen Wandstärke des Oberteils noch wirksam auf die Verbindungsstellen übertragen werden, weshalb ein Andruck auf das Oberteil im mittleren Bereich ausreicht, um alle peripheren Verbindungsstellen unter Druck zu setzen und zu schließen. Dies kann auch mittels eines leichten Schlages erreicht werden.As a result of a uniform positioning and the closing process is significantly favored. For a lesser pressure is now sufficient to produce the clip connections. Also, a lesser pressure can be transferred even with a small wall thickness of the upper part still effective on the connection points, which is why a pressure on the upper part in the central region is sufficient to put all the peripheral junctions under pressure and close. This can also be achieved by means of a light blow.
Vorteilhaft sind bei einer Verpackung mit eckigem Grundriss Gleit- und Zentrierflächen in den Eckbereichen vorgesehen.Advantageously, sliding and centering surfaces are provided in the corner areas in a package with angular plan.
Zweckmäßigerweise sind im Bereich der Gleit- und Zentrierflächen Rastnasen angeordnet.Appropriately, locking lugs are arranged in the region of the sliding and centering surfaces.
Nach einem weiteren Vorschlag schließt sich an den Rand des Unterteils eine laschenförmige Verlängerung als Handhabe an.According to another proposal, a tab-shaped extension joins as a handle on the edge of the lower part.
Bei einer Weiterbildung ist der Rand des Oberteils im Bereich der Handhabe in etwa auf dessen Länge verbreitert, wobei eine Ausnehmung unmittelbar über der Handhabe des Unterteils vorgesehen ist.In a further development of the edge of the upper part in the region of the handle is widened in about its length, wherein a recess is provided directly above the handle of the lower part.
Vorteilhaft ist das Oberteil als Tiefziehteil aus transparentem Kunststoff ausgebildet.Advantageously, the upper part is designed as a deep-drawn part of transparent plastic.
Zweckmäßigerweise ist das Unterteil mit seinem Rand nachgiebiger als das Oberteil mit seinen Rastnasen.Conveniently, the lower part is more compliant with its edge than the upper part with its locking lugs.
In weiterer Ausgestaltung des Erfindungsgedankens ist der Rand des Unterteils im Querschnitt stufenförmig mit mindestens einer Stufe ausgebildet.In a further embodiment of the inventive concept, the edge of the lower part is formed stepwise in cross section with at least one step.
Nach einem weiteren Vorschlag schließt der stufenförmige Rand nach außen mit einem schmalen, horizontalen Randstreifen ab.According to another proposal, the step-shaped edge closes outwards with a narrow, horizontal edge strip.
Vorteilhaft sind Unterteil und Oberteil so bemessen, dass nach dem losen Aufsetzen des Oberteils auf das Unterteil sich die Rastnasen des Oberteils auf dem horizontalen Randstreifen des Unterteils abstützen.Advantageously, lower part and upper part are dimensioned so that after the loose fitting of the upper part on the lower part, the locking lugs of the upper part are supported on the horizontal edge strip of the lower part.
Zweckmäßigerweise sind die Rastnasen im Wesentlichen aus zwei Schrägen gebildet, von denen die obere von oben nach unten und die untere von unten nach oben ins Innere des Oberteils vorspringen.Conveniently, the locking lugs are essentially formed of two slopes, of which the top projecting from top to bottom and the bottom from bottom to top inside the shell.
Die zuletzt erwähnten Ausführungsformen, bei denen der Rand des Unterteils stufig ausgebildet ist, zeichnen sich dadurch aus, dass die jeweilige Verpackung sich bereits mit geringem Anpressdruck sicher verschließen lässt. So bewirkt die stufige Ausbildung, dass sich das Oberteil ohne größere Widerstände auf das Unterteil bis in Schließposition absenken lässt, wobei zuletzt die Rastnasen des Oberteils Zentrierfunktion übernehmen. Um von dieser günstigen Schließposition zu Clipverbindungen zu gelangen, brauchen sich lediglich die Rastnasen noch über den schmalen Randstreifen am Unterteil zu schieben, worauf diese kurz nach unten und innen ausweichen und nach dem Absenken der Rastnasen wieder ihre alte Lage einnehmen.The last-mentioned embodiments, in which the edge of the lower part is formed in stages, are characterized by the fact that the respective packaging can be securely closed even with little contact pressure. Thus, the stage design causes the upper part can lower without major resistance to the lower part to the closed position, with the last take over the locking lugs of the upper centering function. To get from this favorable closed position to clip connections, only the locking lugs need to push on the narrow edge strip on the lower part, whereupon they dodge downwards and inwards and take their old position again after lowering the locking lugs.
Während der Randstreifen nach unten leichter ausweichen kann, ist er nach oben nicht so einfach zu verformen, weil sich eine Bewegung nach oben gegen die stufige Ausbildung, d. h. deren Verformungswiderstände richtet. So kann also trotz einer geringen Anpresskraft für das Verschließen eine hohe Ausziehkraft für das Öffnen erforderlich werden. Damit lässt sich eine erfindungsgemäße Verpackung auch sicher und dauerhaft gestalten.While the edge strip can dodge down more easily, it is not so easy to deform upwards, because a move up against the gradual training, ie their resistance to deformation. Thus, despite a low contact pressure for closing a high extraction force for opening may be required. This makes it possible to make a packaging according to the invention safe and durable.
