Definitions
- the invention relates to a liner for a container which can be closed with a lid and consists of thin-walled, flexible plastic, the upper edge of the liner being provided with an outwardly extending retaining collar.
- Such linings of containers are known as flexible inner casings with cover films.
- So-called round-bottom bags with lid foils are used for cylindrical bodies, so-called shape inliners, which also enclose the edge of the vessel (vessel border), have proven effective for bulbous vessels.
- a deep-drawn film is usually used, which is adapted to the inner shape of the lid and encloses the border.
- a major disadvantage of the separate assignment of inliners and cover foils is that the container edge (Bordur) is enclosed twice with foil. As a result, the necessary sealing effect is not infrequently impaired because the seal running around in the sealing groove of a container lid does not adequately compensate for the double foil overlay on the barrel edge.
- Another lack of sealing in film systems is the high surface sliding effect of flexible films made of high-pressure polyethylene (LDPE), which are mainly used because of their otherwise generally good properties.
- LDPE high-pressure polyethylene
- the object on which the present invention is based is to find a lining of wide-neck lid containers which avoids the disadvantages described above in terms of assignment and sealing, without neglecting their advantages.
- This object is achieved in that an inwardly projecting, circumferential support edge is provided below the retaining collar, on which a cover rests.
- This new type of holding collar serves either as a level for thermoplastic connection with a cover film of any type or as a support for a loosely assigned film cut. It is crucial that the molded-on indentation is located immediately below the inner groove edge of a lid in order not to impair the fill level.
- the particularly advantageous embodiment of the invention also creates an often desired membrane effect for pressure equalization in the lid cavity.
- a seam connection between the inliner and the cover film can take place inside or outside a molding tool, as can the assignment of the required filling and emptying openings.
- a container of this type achieves other advantages, however, if the filling and emptying openings in the area of the cover film are shaped as a slip cup. If closures are inserted in this way, they cannot hinder the lid closure flush with the inside of the lid, they can survive transport better and they can be emptied more easily. The same functions can later be performed via a container replacement lid with corresponding openings and holding devices as with a bunghole lid barrel.
- the complete emptying is also possible because clean disposal by removing the light, thin-walled and flexible inliner, which can be folded to a minimum volume after the remaining content has been pressed out via the closure opening and can then be closed drip-free with the closure cap.
- the closure function is to be assessed differently via a loose cover film overlay.
- a self-locking film disc can be placed on the neck of a container. If the exact dimensions are specified, the inner edge of the cover sealing groove presses onto the attached cover plate in the area of the inner circumferential plane of the retaining collar (Level of evasion). In many cases, this seal is sufficient to prevent fill materials from escaping into the upper deck area. It is also advantageous, however, to have a molded-on film disc with edges that are angled upward and then protrude into the groove. Finally, a foil cover disk can have a seal for the retaining collar or can be located thereon.
- cover film for locking purposes is conceivable if the holding collar itself serves as a locking element. Then the outer edge of the cover sheet must be formed with a uniform slight counter-evasion in order to snap under the retraction edge of the retaining collar when pressed on. As a result, the middle surface of the cover film lies slightly below the level of the holding collar.
- the retaining collar itself can be designed in multiple forms.
- the upper level is usually flat / straight for the purpose of a thermoplastic connection, while the lower return can be guided in the same way or, due to the better removal from the mold, is returned to the inliner wall at an oblique angle or in an arc.
- FIGS. 1 to 11 A section through the upper edge of a container with a lid is shown in FIGS. 1 to 11.
- the container can have, for example, the shape shown in DE-OS 1813687 and a cylindrical shape.
- Figure 1 shows a cylindrical container 1, in which the border of the container edge 12 is approximately circular in cross section.
- a lid 2 is placed on this container 1, which has a groove 11 corresponding to the border 12.
- the lining 4 which consists of thin-walled, flexible and thermoplastically deformable plastic, primarily of LDPE, HDPE, PP or coextrusions in the end wall thicknesses, preferably less than 250 ⁇ - depending on the lining volume.
- this lining 4 has an inwardly projecting, peripheral support edge 5.
- a holding collar 18 is formed on the lining 4, which is placed on the border 12 of the container 1 and which is held elastically by a seal 3 inserted into the space between the border 12 and the groove 11.
- the seal 3 can be firmly connected to the groove 11 of the cover 2.
- the cover 6, which preferably also consists of the same types of plastic, is placed on the support edge 5 and is held in this position by the cover 2.
- the lining 4 with its peripheral support edge 5 is located in a bulbous container 1, preferably made of plastic, which ends in a border 12.
- the cover 2 is also made of plastic and has a molded-in border urinal groove 11.
- the cover 6 is connected to the support edge 5 by an endless weld 8.
- a projection 20 extends downward on the inside of the cover 2. It can be in length be designed so that it presses against the cover film 6 in the closed state of the container.
- FIG. 3 shows an embodiment in which the support edge 5 of the container lining 4 is formed by a flange-like, internal connecting seam 8 between the holding collar 18 and the lining 4.
- Figure 4 corresponds essentially to the embodiment shown in Figure 2. However, it additionally shows a fill and drainage bung 9 welded into the cover 6 with a closure cap attached.
- Figure 5 shows a container 1, as shown in Figures 2 and 4.
- the peripheral support edge 5 according to the invention is provided with a peripheral recess 13 into which the cover 6 can be inserted with a corresponding groove and can be pressed in by the projection 20 provided on the cover 2.
- FIG. 6 is an embodiment corresponding to FIG. 5, in which the support edge is provided with an essentially wedge-shaped groove 13 into which the cover 6 engages and on the inclined edge of which this cover 6 can be pressed by the projection 20 of the cover 2.
- FIG. 7 shows an embodiment in which the support edge 5 has a circumferential recess 13 into which a seal 14 is inserted, against which the edge of the cover 6 can be pressed in a sealing manner with the projection 20 of the cover 2. This can be supported by inserting a dimensionally stable support ring 21 with a horizontal surface into the circumferential evasion.
- FIG. 8 shows an embodiment corresponding to FIG. 7, in which a groove-shaped recess 13 is formed in the support edge 5, into which the correspondingly formed one groove-shaped edge 15 of the cover 6 can be used.

Description
Die Erfindung betrifft eine Auskleidung für einen mit einem Deckel verschließbaren Behälter bestehend aus dünnwandigem, flexiblem Kunststoff, wobei der obere Rand der Auskleidung mit einem nach außen übergreifenden Haltekragen versehen ist.The invention relates to a liner for a container which can be closed with a lid and consists of thin-walled, flexible plastic, the upper edge of the liner being provided with an outwardly extending retaining collar.
Derartige Auskleidungen von Behältnissen sind als flexible Innenhüllen mit Abdeckfolien bekannt. Bei zylindrischen Körpern kommen sogenannte Rundbodensäcke mit Deckelfolien zu Einsatz, bei bauchigen Gefäßen haben sich sogenannte Form-Inliner bewährt, die auch den Gefäßrand (Gefäß-Bordur) umschließen. Zwecks Sauberhaltung des Deckels und zum Druckausgleich wird meist eine tiefgezogene Folie benutzt, die der Innenform des Deckels apgepaßt ist und die Bordur umschließt. Solche Innenhüllen und Deckelfolien sind in der DE-A-1813687 beschrieben.Such linings of containers are known as flexible inner casings with cover films. So-called round-bottom bags with lid foils are used for cylindrical bodies, so-called shape inliners, which also enclose the edge of the vessel (vessel border), have proven effective for bulbous vessels. In order to keep the lid clean and to equalize pressure, a deep-drawn film is usually used, which is adapted to the inner shape of the lid and encloses the border. Such inner casings and cover films are described in DE-A-1813687.
Die mit diesen Auskleidungen erzielten Vorteile liegen vor allem darin, daß die Gefäße vor Verunreinigungen geschützt werden und nach Entleerung und Entfernen der Auskleidungselemente sofort wieder verwendet werden können.The advantages achieved with these linings are primarily that the vessels are protected from contamination and can be used again immediately after the lining elements have been emptied and removed.
Ein wesentlicher Nachteil der getrennten Zuordnung von Inliner und Deckelfolien besteht darin, daß der Behälterrand (Bordur) zweifach mit Folie umschlossen wird. Dadurch wird nicht selten der notwendige Dichtungseffekt beeinträchtigt, weil die in der Dichtungsnut eines Behälterdeckels umlaufende Dichtung die doppelte Folienauflage am Faßrand ungenügend ausgleicht. Ein weiterer Dichtungsmangel bei bei Folienanlagen besteht in der hohen Oberflächengleitwirkung flexibler Folien aus Hochdruck-Polyäthlyen (LDPE), wie sie wegen ihrer sonst insgesamt guten Eigenschaften überwiegend zum Einsatz kommen. Auch wenn diese Dichtung, wie in der DE-A-3838182 beschrieben, in die Nut der Deckelfolie eingebracht ist, ist zumindest die Be- und Entdeckelung durch die doppelte Folienauflage behindert, da die Behälterdeckel, besonders solche aus Kunststoff, so konzipiert sind, daß sie vornehmlich Deckelgefäße ohne Inliner und Deckelfolien dicht verschließen. Entsprechend eng sind deshalb die Toleranzen zwischen Deckel und Faßbordur bemessen. Die Zulassung einer geprüften Behälterbauart ist darauf abgestimmt.A major disadvantage of the separate assignment of inliners and cover foils is that the container edge (Bordur) is enclosed twice with foil. As a result, the necessary sealing effect is not infrequently impaired because the seal running around in the sealing groove of a container lid does not adequately compensate for the double foil overlay on the barrel edge. Another lack of sealing in film systems is the high surface sliding effect of flexible films made of high-pressure polyethylene (LDPE), which are mainly used because of their otherwise generally good properties. Even if this seal, as described in DE-A-3838182, is introduced into the groove of the cover film, at least the capping and uncapping is hampered by the double film support, since the container cover, especially those made of plastic, are designed so that them primarily Seal the lid containers tightly without inliners and lid foils. The tolerances between the lid and the barrel border are accordingly narrow. The approval of a tested container design is coordinated with it.
Die der vorliegenden Erfindung zurgundeliegende Aufgabe besteht darin, eine Auskleidung von Weithals-Deckel-Gebinden zu finden, welche die vorweg beschriebenen Nachteile in Zuordnung und Dichtung vermeidet, ohne deren Vorteile zu vernachlässigen.The object on which the present invention is based is to find a lining of wide-neck lid containers which avoids the disadvantages described above in terms of assignment and sealing, without neglecting their advantages.
Diese Aufgabe wird dadurch gelöst, daß unterhalb des Haltekragens ein nach innen vorstehender, umlaufender Auflagerand vorgesehen ist, auf dem eine Abdeckung aufliegt. Dieser neuartige Haltekragen dient entweder als Ebene zum thermoplastischen Verbinden mit einer, wie immer gearteten, Deckelfolie oder als Auflage für einen lose zugeordneten Folienzuschnitt. Entscheidend ist, daß sich die angeformte Hinterziehung jeweils unmittelbar unterhalb der inneren Nutkante eines Deckels befindet, um die Füllhöhe nicht zu beeinträchtigen. Durch die besonders vorteilhafte Ausführung der Erfindung wird auch ein oft erwünschter Membraneffekt zum Druckausgleich im Deckelhohlraum erzeugt.This object is achieved in that an inwardly projecting, circumferential support edge is provided below the retaining collar, on which a cover rests. This new type of holding collar serves either as a level for thermoplastic connection with a cover film of any type or as a support for a loosely assigned film cut. It is crucial that the molded-on indentation is located immediately below the inner groove edge of a lid in order not to impair the fill level. The particularly advantageous embodiment of the invention also creates an often desired membrane effect for pressure equalization in the lid cavity.
Zu unterscheiden sind vor allem die Ergebnisse bei einer Nahtverbindung auf der Ebene des Auflagerandes und einer nur losen Auflage eines geeigneten Folienzuschnitts.Above all, a distinction must be made between the results of a seam connection at the level of the support edge and only a loose support of a suitable film cut.
Bei einer festen Nahtverbindung wird eine bisher noch unbekannte Inlinerart erzielt. Bekannt waren geschlossene Folien-Inliner mit dem Nachteil, daß sie über keinen passenden Kragenrand verfügten. Angebotene Verlängerungen der Folienwand ermöglichten zwar ein Umschlag über den Behälterrand, waren aber so nur sehr zeit- und personalaufwendig zu handhaben. Ihre Auslegung erwies sich auch oft als mangelhaft und eine Befüllung als stark behindert, da die Zwischenwandluft aus dem Bereich Behälterwand/Folienauskleidung nicht entweichen konnte. Ohne diesen Umschlag über den Behälterrand ließen sich solche flexible Folienhüllen schlecht befüllen, da es ihnen an Standkraft fehlte. Auch mit einem Überstand der angeschweißten Oberboden-Deckelscheibe ließ sich das Problem nicht zufriedenstellend lösen. In diesem Falle kamen Dichtprobleme hinzu, da der Folienüberstand nur unter Faltenbilung im Rand/Nutbereich unterzubringen war.With a firm seam connection, a hitherto unknown type of inliner is achieved. Closed film inliners were known with the disadvantage that they did not have a matching collar edge. Offered extensions of the film wall made it possible to turn the container over the edge of the container, but were very time-consuming and personnel-intensive to handle. Their design also often proved to be inadequate and filling was severely hindered, since the partition wall air could not escape from the area of the container wall / foil lining. Without this envelope over the edge of the container, such flexible film casings would be difficult to fill because they lacked stability. The problem could not be solved satisfactorily even with a protrusion of the welded top cover plate. In this case sealing problems were added, since the film overhang could only be accommodated with fold formation in the edge / groove area.
Gleichartige aber steife Inliner konnten wegen Wegfall des Kragenrandes diese Randfalten-und Befüll-Nachteile zwar vermeiden, ließen sich in ihrer stabilen Form jedoch oft nur relativ starkwandig herstellen, und waren deshalb schwer zu entsorgen. Schließlich eigneten sie sich nur für zylindrische und andere geradwandige Gefäße, da man sie in bauchige Gebinde weder einbringen noch aus diesen entfernen konnte. Die der Erfindung zugrundeliegende Inlinerart in geschlossener Ausführung erfüllt dagegen alle Forderungen nach schneller und paßgerechte Auslegung bei gleichzeitiger Randhalterung ,verbesserter Dichtvoraussetzung, einwandfreier Schnellbefüllung, bewährter Entleerung und sauberer, kostengünstiger Entsorgung.Similar but rigid inliners were able to avoid these edge fold and filling disadvantages due to the omission of the collar edge, but in their stable form they could often only be produced with relatively thick walls and were therefore difficult to dispose of. After all, they were only suitable for cylindrical and other straight-walled vessels, since they could not be inserted into or removed from bulbous containers. The inliner type on which the invention is based, on the other hand, fulfills all requirements for quick and fit design with simultaneous edge support, improved sealing requirements, perfect quick filling, proven emptying and clean, inexpensive disposal.
Eine Nahtverbindung zwischen Inliner und Deckelfolie kann innerhalb oder außerhalb eines Formwerkzeugs geschehen, ebenso die Zuordnung der erforderlichen Befüll-und Entleerungsöffnungen. Ein Gebinde dieser Art erzielt aber noch andere Vorteile, wenn die Füll- und Entleerungsöffnungen im Bereich der Deckelfolie als Stülpnapf ausgeformt sind. Werden Verschlüsse so eingebracht, können sie innendeckelbündig den Deckelverschluß nicht behindern, den Transport besser überstehen und die Entleerung erleichtern. Über einen Behälter-Wechseldeckel mit entsprechenden Öffnungen und Haltevorrichtungen sind später gleiche Funktionen erfüllbar, wie bei einem Spundloch-Deckelfaß. Die Restlosentleerung ist ebenso möglich, weil eine saubere Entsorgung durch Entnahme des leichten, dünnwandigen und flexiblen Inliners, der nach dem Ausdrücken des Restinhaltes über die Verschlußöffnung auf ein geringstes Volumen zusammenfaltbar ist und dann mit der Verschlußkappe tropffrei verschlossen werden kann.A seam connection between the inliner and the cover film can take place inside or outside a molding tool, as can the assignment of the required filling and emptying openings. A container of this type achieves other advantages, however, if the filling and emptying openings in the area of the cover film are shaped as a slip cup. If closures are inserted in this way, they cannot hinder the lid closure flush with the inside of the lid, they can survive transport better and they can be emptied more easily. The same functions can later be performed via a container replacement lid with corresponding openings and holding devices as with a bunghole lid barrel. The complete emptying is also possible because clean disposal by removing the light, thin-walled and flexible inliner, which can be folded to a minimum volume after the remaining content has been pressed out via the closure opening and can then be closed drip-free with the closure cap.
Anders ist die Verschlußfunktion über eine lose Deckelfolien-Auflage zu beurteilen. Erstmalig kann innerhalb eines Gebindes am Gebindehals eine selbstsichernde Folienscheibe aufgelegt werden. Der innere Rand der Deckel-Dichtungsnut setzt sich bei exakter Maßvorgabe pressend auf die aufgelegte Deckelscheibe im Bereich der innenumlaufenden Ebene des Haltekragens (Hinterziehungsebene). In vielen Fällen reicht diese Abdichtung aus, um einen Austritt von Füllmaterialien in den oberen Deckbereich zu verhindern. Vorteilhaft ist, jedoch auch eine angeformte Folienscheibe mit nach oben abgewinkelten Kanten, die dann in die Nut hineinragen. Schließlich kann eine Folienabdeckscheibe zum Haltekragen eine Dichtung aufweisen oder eine solche sich auf dieser befinden.The closure function is to be assessed differently via a loose cover film overlay. For the first time, a self-locking film disc can be placed on the neck of a container. If the exact dimensions are specified, the inner edge of the cover sealing groove presses onto the attached cover plate in the area of the inner circumferential plane of the retaining collar (Level of evasion). In many cases, this seal is sufficient to prevent fill materials from escaping into the upper deck area. It is also advantageous, however, to have a molded-on film disc with edges that are angled upward and then protrude into the groove. Finally, a foil cover disk can have a seal for the retaining collar or can be located thereon.
In besonderen Fällen kann es vorteilhaft sein, in die obere Ebene des Haltekragens eine Schnappmulde zu ziehen, um eine gegengeformte Oberfolie sicher zu arretieren.In special cases, it can be advantageous to pull a snap recess into the upper level of the holding collar in order to securely lock a counter-shaped upper film.
Eine andere Form der Abdeckfolie zwecks Arretierung ist denkbar, wenn der Haltekragen selbst als Arretierelement dient. Dann muß der äußere Rand der Abdeckfolie mit einer gleichförmigen geringen Gegenhinterziehung ausgebildet sein, um beim Aufdrücken unter der Hinterziehungskante des Haltekragens einzurasten. Dadurch liegt die mittlere Fläche der Abdeckfolie geringfügig unterhalb der Ebene des Haltekragens.Another form of the cover film for locking purposes is conceivable if the holding collar itself serves as a locking element. Then the outer edge of the cover sheet must be formed with a uniform slight counter-evasion in order to snap under the retraction edge of the retaining collar when pressed on. As a result, the middle surface of the cover film lies slightly below the level of the holding collar.
Der Haltekragen selbst kann in vielfacher Form ausgebildet sein. Die obere Ebene ist in aller Regel zum Zwecke einer thermoplastischen Verbindung flach / gerade, während die untere Rückführung gleicheben geführt sein kann oder wegen der besseren Entformung aus einem Werkzeug im schrägen Winkel oder bogenförmig an die Inlinerwand zurückgeführt ist.The retaining collar itself can be designed in multiple forms. The upper level is usually flat / straight for the purpose of a thermoplastic connection, while the lower return can be guided in the same way or, due to the better removal from the mold, is returned to the inliner wall at an oblique angle or in an arc.
Hervorzuheben ist, daß in beiden Ausführungsfällen, nämlich einer Hinterziehung oder Folienlippe zwecks Nahtverbindung oder für eine lose Auflage der Abdeckfolie, die Befülleigenschaft des Inliners durch das Entweichen von Zwischenwandluft über formausgeschweißte Hohlraumkanäle im Bordurenkragen des Inliners erhalten bleiben. Beim Einsatz einer zweiten Form-Deckelfolie wäre dieser Effekt behindert, ebenso eine schnelle Deckelung, da das Deckel-Luftpolster keine Auslaßkanäle vorfindet.It should be emphasized that in both cases, namely an evasion or lip for the purpose of a seam connection or for a loose covering of the cover film, the filling property of the inliner is retained by the escape of intermediate wall air via welded-out cavity channels in the border collar of the inliner. This effect would be hindered when using a second molded cover film, as would a quick cover, since the cover air cushion does not have any outlet channels.
