Abstract

A detachable string of inflatable bladders (14/114), which are closed at one end in each case (22/122) and are partially closed at their other end (24/124), is vented by detaching their closure stoppers (16/116) in order to reduce their packaging volume for return transport or storage. In one embodiment, the continuation (16) of the stopper at the closed end (22) of each bladder (14) also forms the coupling with the filling and venting passage (18), at the end (24) which is partially closed thereby, of another bladder (14). In a second embodiment, the closed end (122) of a bladder (114) bears a loop (127) into which the closure stopper (116), attached by the bearer (125) to the partially closed end (124) of another bladder (114), is detachably inserted as a coupling. In this case, the venting of the bladders (114) is possible without detaching the coupling and closure of the bladders (114) is only required for renewed use. For rolling up again (11), individual bladders (114) are inserted with their closure stopper (116) into the loop (127) of the bladder (114) which was rolled up last in each case. During use, the bladders (14/114) are used as universal object protection padding for packaging, in transport or storage containers. <IMAGE>

Description

Die Erfindung bezieht sich auf ein zusammenkuppelbares, aufblasbares Verpackungsmaterial und Methode seiner Anwendung, wobei zum Transport, oder zur Lagerung bestimmte Objekte durch schockabsorbierende Polster oder stabilisierende Einsaetze vor physikalischen Einwirkunggen von aussen geschuetzt werden.The invention relates to an interconnectable, inflatable packaging material and method of its use, wherein objects intended for transport or storage are protected from physical influences from outside by shock-absorbing pads or stabilizing inserts.

Geformte Schaumkoerper und luftgefuellte Blasenmaterialien sind als Polsterungs-, Fuell- und Stabilisierungsmedien im Verpackrungsgewerbe einschlaegig bekannt und in weitverbreitetem Gebrauch. Solche Verpackungsmaterialien werden im Allgemeinen in grossen Volumen von deren Hersteller zum Verpacker transportiert, wo sie vor der Anwendung einen beachtlichen Lagerraum einnehmen. Andere, luftgefuellte oder aufgeschaeumte Verpackungsmaterialien werden, um Transport- und Lagerungskosten einzusparen, am Ort der Verpackung hergestellt. Solche Materialien sind fuer Industriebetriebe wenig zufriedenstellend, da zusaetzliche Vorrichtungen und Rohmaterialbeschaffung unterhalten werden muessen. In vielen Faellen muss zum Aufschaeumen mit schaedlichen Gasen gearbeitet werden. Dem Endverbraucher verbleibt die Last des Verpackungsabfalls. Derartige Einweg - Materialien belasten Muellbeseitigung und -deponien und geben Grund zu Bedenken im Umweltschutz.
Verschiedene Arten von aufblasbaren Verpackungen sind bekannt und einige davon geeignet zur Wiederverwendung. Beispielsweise Ainsworth ( US Patent Nr. 4,569,082 ), enthuellt einen aufblasbaren Einsatz in Verbindung mit einem bestimmten Transportbehaelter. Ein Taschenelement ist dabei in den Behaelter eingesetzt um Objekte zu transportieren. Nach dem Fuellen der Taschen kann der Behaelter geschlossen und eine Blase mit einem Gas gefuellt werden, um die enthaltenen Objekte zu schuetzen. Als Transportmittel sind der Behaelter und die Blase wiederverwendbar, Ainsworths Erfindung hat jedoch den Nachteil, dass die Gasblase nur fuer einen bestimmten, ihr zugeordneten Behaelter, Anwendung findet und damit fuer einen unterschiedlich dimensionierten Behaelter ungeeignet ist. Weiterhin waere Ainsworths Vorrichtung ungeeignet fuer den Transport von Objekten groesseren Gewichts, da die Gasblase keine Seitenwaende zur Stabilisierung und zum Schutz der beinhalteten Objekte aufweist.
Presnik ( US Patent Nr. 3,889,743 ) veranschaulicht einen aufblasbaren Einsatz fuer einen Behaelter, wobei eine Anzahl doppelwandiger thermoplastischer Panelen zu einer Matte geformt sind, die, wenn entsprechend gefaltet, in einen passenden Behaelter eingelegt werden kann. Einzelne Kammern sind untereinander durch Kanaele verbunden und eine Kammer ist mit einem Ventil versehen, welches an die Verschlusseite des Behaelters zu liegen kommen soll. Hiernach kann ein Gas eingefuellt und ein Objekt, oder mehrere in den an den Seiten gepolsterten Behaelter eingelegt werden, ohne dass jedoch mehrere Objekte gegenseitig geschuetzt werden. Waehrend diese Loesung fuer einen schwereren Gegenstand geeignet sein mag, gibt Presnik fuer seine Erfindung nur den Zweck der Isolierung an. In jedem Fall hat auch diese Erfindung den Nachteil, dass fuer jeden unterschiedlich dimensionierten Behaelter eine neue, passende Matte angefertigt werden muesste.
Letzteres gilt auch fuer die von Liquefreeze / Morrison ( GB Patent Nr. 22043/60 - 958,500 ) geltend gemachte Erfindung eines Isolierbehaelters. Mehrere aufblasbare Panelen mit integriertem Isoliermaterial, werden durch Zusammenschnueren, oder anderweitig, zu einem wuerfelfoermigen Behaelter errichtet, der beispielsweise zum Versand von tiefgefrorenen Lebensmitteln Anwendung findet. Diese Vorrichtung von Liquefreeze ermoeglicht zwar eine Volumenreduzierung des Isolierbehaelters selbst, und dessen Zerlegung in Einzelpanelen, ist jedoch nicht als flexible Schutz- oder Fuellverpackung, im Sinne der vorliegenden Erfindung anwendbar.
Um die beschriebenen Probleme zu ueberkommen, benoetigt die Verpackungsindustrie ein universell anwendbares, preisguenstig herstellbares, umweltfreundliches und leicht handzuhabendes Verpackangsmaterial, das seine Vorteile, moeglichst unter Vermeidung von zusaetzlichen Investitionen fuer den Anwender, und kostensparend gegenueber herkoemmlicher Techniken, zugaenglich macht.Shaped foams and air-filled bladder materials are well known as cushioning, filling and stabilizing media in the packaging industry and are in widespread use.

Various types of inflatable packaging are known and some of them are suitable for reuse. For example, Ainsworth (U.S. Patent No. 4,569,082) discloses an inflatable insert in connection with a particular transport container. A pocket element is inserted in the container to transport objects. After filling the bags, the container can be closed and a bladder filled with a gas to protect the objects it contains. The container and the bladder can be reused as a means of transport, but Ainsworth's invention has the disadvantage that the gas bladder is only used for a specific container assigned to it and is therefore unsuitable for a container of different dimensions. Furthermore, Ainsworth's device would be unsuitable for the transport of objects of greater weight, since the gas bubble has no side walls for stabilization and to protect the contained objects.
Presnik (US Patent No. 3,889,743) illustrates an inflatable insert for a container, in which a number of double-walled thermoplastic panels are formed into a mat which, when folded appropriately, can be placed in a suitable container. Individual chambers are connected to each other by channels and one chamber is provided with a valve which should come to rest on the closure side of the container. After this, a gas can be filled and one or more objects can be inserted into the container padded on the sides without, however, protecting several objects from one another. While this solution may be suitable for a heavier object, Presnik only provides the purpose of isolation for his invention. In any case, this invention also has the disadvantage that a new, suitable mat would have to be made for each container of different dimensions.
The latter also applies to the invention of an insulated container claimed by Liquefreeze / Morrison (GB Patent No. 22043/60 - 958,500). Several inflatable panels with integrated insulating material are assembled by tying them together, or otherwise, to form a cube-shaped container, which is used, for example, for shipping frozen food. Although this device from Liquefreeze enables a reduction in the volume of the insulating container itself and its disassembly into individual panels, it cannot be used as flexible protective or filling packaging in the sense of the present invention.
In order to overcome the problems described, the packaging industry needs a universally applicable, inexpensive to produce, environmentally friendly and easy-to-use packaging material which makes its advantages accessible, while avoiding additional investments for the user, and saves costs compared to conventional technologies.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Anspruechen gekennzeichnet ist, loest die Aufgabe, ein universell anwendbares, preisguenstig herstellbares, umweltfreundliches, leicht und sauber handzuhabendes Verpackungsmaterial bereitzustellen, unter Verwendung von aneinanderreihbarer, aufblasbarer und wiederholt entlueftbarer Blasen, die mittels einer kombinierten Ventilstoepsel - Kupplung aneinandergereiht werden, um eine, in Form und Volumen beliebige Objektschutz- und Fuellverpackung zu gestalten, oder um, in entlueftetem Zustand, diesselben fuer Lagerung, oder Rueckversand, raumsparend und fuer ihren erneuten, erleichterten Gebrauch vorbereitet, aufzurollen.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem of providing a universally applicable, inexpensive to produce, environmentally friendly, easy and clean-to-use packaging material, using stringable, inflatable and repeatedly ventilated Bubbles, which are strung together by means of a combined valve plug coupling, in order to design any object protection and filling packaging, in terms of shape and volume, or to prepare the same for storage or return, in a vented state, to save space and to prepare it for its renewed, easier use to roll up.

Die durch die Erfindung erreichten Vorteile sind im Wesentlichen darin zu sehen, dass Aufblasbarkeit und, bei Nichtgebrauch, Entlueftbarkeit einzelner Blasen, eine erhebliche Volumenreduzierung erlauben, die, erste Zulieferung, oder Rueckversand zum Verpacker kostenguenstig ermoeglicht. Die bestehende Schwierigkeit der Abfallbeseitigung beguenstigt solche Ruecksendungen und diese koennen, bei so verkleinertem Volumen, vielfach auf oeffentlichen Transportwegen bewaeltigt werden, was gleichzeitig eine vermindernde Wirkung auf den Zuliefer- Gueterverkehr nimmt.
Das Verpackungsmaterial, im Sinne der Erfindung, ist mit herkoemmlichen Materialien und Maschinen unschwer, und dabei im Preis / Volumenverhaeltnis kostenguenstiger herstellbar, als die meisten handelsueblichen Verpackungen, unbeachtet der moeglichen Einsparungen durch seine Wiederverwendung.
Unter Benutzung geeigneten Rohmaterials ist die Herstellung des erfindungsgemaessen Verpackungsmaterials vollkommen umweltfreundlich durchfuehrbar, und daraus entstehende Abfaelle sind restlos wiederverwertbar ( Recycling ).
Durch eine einfache Steckkupplung wird eine universell anwendbare, in Auslegung, Form und Volumen unbeschraenkt anpassungsfaehige Objektschutz - Verpackung erstellt, die insbesondere fuer kompliziert zu verpackende, empfindliche Artikel und Neuheiten, ohne spezielle Werkzeugkosten, zweckdienlich und kompromisslos angepasst werden kann.
Unter Bereitstellung des Verpackungsmaterials in verschiedenen Wandstaerken, kann dasselbe auch extremen Belastungen angepasst werden.
Das Verpackungsmaterial, im Sinne der Erfindung angewandt, umhuellt einen, oder mehrere Objekte vollstaendig und fuellt Hohlraeume in Transportbehaeltern aus, sodass eine Verlagerung der verpackten Objekte, oder ein Setzen der Verpackung durch Vibrationen, oder Einwirkung von Gravitation, wie dies hei handelsueblichen, losen Fuellstoffen leicht geschieht, ausgeschlossen wird.
Eine erfindungsgemaesse Verpackung zeichnet sich durch sehr hohe Schock - Absorbtion aus, die durch verhaeltnismaessig grosse, elastische Blasen erzielt wird, ein Vorteil, der insbesondere im Transport hochempfindlicher Technik und leicht zerbrechlicher Waren geschaetzt wird und Bedarf findet.
Die Blasen des Verpackungsmaterials werden vorzugsweise mit Luft gefuellt, einem Stoff, der uns frei zur Verfuegung steht, die am Bestimmungsort wieder unbeschaedigt entlassen wird, was bei geschaeumten Materialien nicht der Fall ist, und bei permanent geschlossenen Blasen nur durch deren Zerstoerung erreicht wird. Auch werden hierdurch Luftkissen in Muelldeponien verringert, da die Luft heim Begraben frei entweichen kann.
Der Anpressdruck der gefuellten Blasen ist bei der Fuellung regulierbar und verteilt sich auf verhaeltnismaessig grosse Oberflaechen eines verpackten Objekts, wodurch eine schonend geringe Punktbelastung erzielt wird, waehrend die, den vorzugsweise zylindrischen Blasen eigene, stabile Elastizitaet, ein Scheuern an Objektoberflaechen, wie aus der Anwendung geschaeumter Verpackungsmittel bekannt, nahezu ausschliesst.
Unter Verwendung eines uebergrossen Behaelters und zusaetzlichen Lagen von Verpackungsmaterial, kann der Isolierwert der Verpackung beliebig, und wirksam erhoeht werden.
Das Verpackungsmaterial der Erfindung kann gleichermassen zum Schutz empfindlicher Gegenstaende im offenen Transport, wie zum Beispiel in Zick - Zack Anordnung luftgefuellter Blasen zwischen Fenstern im LKW - Transport, angewandt werden.The advantages achieved by the invention are essentially to be seen in the fact that inflatability and, when not in use, ventability of individual bubbles, allow a considerable reduction in volume, which enables the first delivery or return shipping to the packer at low cost. The existing difficulty of waste disposal favors such returns and these, with such a reduced volume, can often be dealt with on public transport routes, which at the same time has a reducing effect on the supply of goods.
The packaging material, in the sense of the invention, is not difficult with conventional materials and machines, and can be produced more cheaply in terms of price / volume than most conventional packaging, regardless of the possible savings through its reuse.
Using suitable raw material, the production of the packaging material according to the invention can be carried out in a completely environmentally friendly manner, and wastes resulting therefrom are completely reusable (recycling).
A simple plug-in coupling creates a universally applicable object protection packaging that can be flexibly adapted in terms of design, shape and volume, which can be appropriately and uncompromisingly adapted, in particular for sensitive articles and innovations that are difficult to pack, without special tool costs.
By providing the packaging material in different wall thicknesses, the same can also be adapted to extreme loads.
The packaging material, used in the sense of the invention, completely envelops one or more objects and fills cavities in transport containers, so that the packaged objects are displaced, or the packaging is set by vibrations or action from gravitation, as is easily done with commercially available, loose fillers.
A packaging according to the invention is characterized by very high shock absorption, which is achieved by relatively large, elastic bubbles, an advantage which is particularly appreciated in the transport of highly sensitive technology and easily fragile goods and which is in need.
The bubbles of the packaging material are preferably filled with air, a substance that is freely available to us, which is released undamaged at the destination, which is not the case with foamed materials, and is only achieved with permanently closed bubbles by destroying them. This also reduces air cushions in waste disposal sites, since the air can escape freely when buried.
The pressure of the filled bubbles can be regulated during the filling and is distributed over relatively large surfaces of a packaged object, whereby a gently low point load is achieved, while the stable elasticity, which is characteristic of cylindrical bubbles, rubs against object surfaces, as from the application foamed packaging known, almost excludes.
Using an oversized container and additional layers of packaging material, the insulation value of the packaging can be increased arbitrarily and effectively.
The packaging material of the invention can also be used to protect sensitive objects in open transport, such as in a zigzag arrangement of air-filled bubbles between windows in truck transport.

In den Figuren ist ein zusammenkuppelbares, aufblasbares Verpackungsmaterial und eine Methode seiner Anwendung dargestellt, welches in seinem grundsaetzlichen Aufbau aus einzelnen, flexiblen Blasen 14, mit je einem geschlossenen Ende 22 und einem teilweise geschlossenen Ende 24 besteht, wobei ein flexibles, roehrenfoermiges Material von beliebig grossem Querschnitt, in Abstaenden der gewuenschten Blasenlaenge, durch Verschmelzung, Verklebung, oder Vulkanisation, verschlossen 22, oder teilweise verschlossen 24 wird, oder erfindungsgemaesse Blasen 14 / 114, mittels Formen, in entsprechender Weise gegossen, oder geblasen werden.
In einer ersten Verkoerperung der Erfindung wird das teilweise verschlossene Ende 24 jeder Blase 14 mit einem Durchlass 18 versehen, der einen Angriffswulst 13 um seine Aussenwand, und eine radiale Nut 19 an seiner Innenwand besitzt, und, sowohl die Oeffnung zum Befuellen und Entlueften der Blase 14, als auch den Empfaenger der kombinierten, erfindungsgemaessen Verschlusstoepsel- Kupplung zwischen zwei Blasen 14 bildet. Hierzu ist, in der genannten ersten Verkoerperung, das verschlossene Ende 22 jeder Blase 14 mit eine Stoepselfortsatz 16 versehen, der einen Angriffswulst 15 und eine ringfoermige, radiale Feder 17 besitzt. Beide Teile, sowohl der Durchlass 18, als auch der Stoepselfortsatz 16, sind in ihrem Verbindungsbereichmit den Blasenenden 24 / 22, mit der Blasenhaut 14a / 14b konisch verlaufend verjuengt, um die notwendige Elastizitaet fuer ein abgerundetes Aufblaehen der Blasen 14 an diesen Uebergaengen zu gewaehrleisten.
In der Anwendung wird eine Blase 14, vorzugsweise mit Luft, durch ihren Durchlass 18, zu einem gewuenschten Druck gefuellt und mittels des Stoepselfortsatzes 16 einer anderen Blase 14, oder bei alleiniger Anwendung einer Blase 14, ihres eigenen Stoepselfortsatzes 16, verschlossen. Waehrend des Einfuehrens des Stoepselfortsatzes 16 in einen Durchlass 18, spreizt die radiale Feder 17 die elastische Wand desselben, bis sie in die radiale Nut 19 einrasten kann. Daraufhin springt die elastische Wand des Durchlasses 18, von der bezeichneten Dehnung entlastet, in ihre Passform zurueck, um den Stoepselfortsatz 16 nun eng und gasdicht zu umschliessen.
Fuer zusaetzliche Abdichtung, z.B. bei hoeherem Druck in einer Blase 14, ist die Spitze des Stoepselfortsatzes 16 radial, konisch verjuengt und bildet eine flexible Lippe 21, die von hoeherem Innendruck, innerhalb einer Blase 14, an die Innenwand des Durchlasses 18 angedrueckt wird. Der vollzogene Verschluss einer Blase 14 erfuellt, durch Einrasten der Feder 17 in die Nut 19, gleichzeitig die Zusammenkupplung zweier Blasen 14. Dieser Vorgang kann mit beliebig vielen Blasen 14 beliebig oft wiederholt werden, um jedes gewuenschte Verpackungsvolumen herstellen zu koennen. Waehrend die Blasen 14 unterschiedlicher Groesse sein koennen, werden die Dimensionen von Durchlass 18 und Stoepselfortsatz 16 vorteilhafterweise hand- und maschinengerecht, einheitlich gehalten.
In einer zweiten Verkoerperung bildet das verschlossene Ende 122 einer Blase 114 eine Zunge 123, die eine Oese 127 umfaengt. Der Verschlusstoepsel 116 ist bei dieser Verkoerperung mittels eines bandaehnlichen Traegers 125, fest mit dem Durchlass 118 verbunden. Zwei Blasen 114 werden hierbei aneinandergehaengt, indem der Verschlusstoepsel 116 in die Oese 124 eingedrueckt wird, wo er sich mittels der konischen Form und der Nut 126, leicht verklemmen laesst. Waehrend dieses Aneinanderhaengen fuer ein Entlueften der Blasen 114 und deren Aufrollen, ausreichend ist, wird, zum Gebrauch des Verpackungsmaterials, nach Fuellen einer Blase 114, der Verschlusstoepsel 116, unter Anwinkeln der Zunge 123, in den Durchlass 118, bis zum Einrasten der radialen Feder 117 in die radiale Nut 119 eingedrueckt. Der Arbeitsgang des Zusammenkuppelns wird, nach Entstoepseln, bei dieser Verkoerperung, zum Entlueften und Wiederaufrollen, weitgehend erspart, soweit eine Reihe von Verpackungsmaterial aus einem Behaelter, zusammenhaengend entfernt wurde. Die Blasen 114 koennen jedoch, bei Bedarf, vollstaendig getrennt, oder ausgewechselt werden, indem der Verschlusstoepsel 116 einer Blase 114, mit geringem Kaftaufwand, aus der Oese 124 einer anderen Blase 114 geloest wird. Diese Verkoerperung ermoeglicht ebenfalls Transport und Lagerung grosser Nutzvolumen von Verpackungsmaterial in wirtschaftlich, kompakter Weise, da Blasen 114 nach Entlueftung zu einer Rolle 11, verhaeltnismaessig kleinen Volumens, aufgerollt werden koennen.
Die Blasen 14 / 114 sind, erfindungsgemaess, aus einem flexiblen, haltbaren, luftdichten Material, wie Vinyl, oder Gummi, angefertigt. Die Wandstaerke der Blasenhaut 14a / 14b soll nach ihrer Belastung im Einsatz gewaehlt werden. Schwere Objekte beduerfen hierbei groesserer Materialstaerke. Laenge und Querschnittdimensionen der Blasen 14 / 114 koennen ebenfalls, Im Einklang mit ihrem geplanten Einsatz, sinngemaess festgelegt werden.
Zum Schutz des Verpackungsmaterials der Erfindung, vor scharfkantigen, oder spitzen Objektteilen koennen, vor dem Verpacken, verschiedene Schutzschilder 130a - 130d um ein Objekt 142 umgespannt werden, die vorzugsweise aus einem unzerbrechlichen Material wie Nylon hergestellt, und an ihrer Aussenseite generell abgerundet sind. Die jeweilige Anwendung ist abhaengig von der Gestalt eines zu verpackenden Gegenstandes. Ein elastisches Spannband 131 wird dabei, jeweils nach Ansetzen eines Schutzschildes 130a -130d, um den Gegenstand gespannt.
Zu einer Anwendung der Erfindung wird eine Reihe von Blasen 14 mit Luft gefuellt, waehrend der Durchlass 18 jeder gefuellten Blase 14 mit dem Stoepselfortsatz 16, einer weiteren Blase 14 verschlossen, und unter fortgesetztem Fuellen und Zusammenkuppeln, eine Kette von Blasen 14 hergestellt, mit deren Hilfe der Boden eines Versandbehaelters 140, im Zickzack- Muster ausgekleidet wird, bis dieser Boden bedeckt ist. Das Ende der zuletzt, zum Verschluss einer Blase 14 benutzten, unaufgeblasenen Blase 14, haengt dabei vorteilhafterweise frei ueber den Rand des Behaelters 140. Das Objekt 142 wird daraufhin, etwa mittig, auf die hergestellte Matte von Blasen 14 gesetzt, bevor die Kette von Blasen 14, unter Aufblasen und Zusammenkuppeln fortgesetzt, und diese, entlang des seitlichen Umfangs des Objekts 142, satt, zwischen dieses und die Wand des Behaelters 140 eingeschoben wird, bis alle Seiten des Objekts142 ausreichend gepolstert sind. Anschliessend wird die Kette von Blasen 14 solange erweitert, bis, wie in Figur 8c veranschaulicht, durch Abdecken im Zickzack- Muster, das Objekt 142 vollstaendig abgedeckt ist. Der Versandbehaelter 140 ist nun bereit, weitere, zu verpackende Gegenstaende zu empfangen, oder, wenn er hiermit vollstaendig gefuellt ist, verschlossen zu werden.
Es ist bei der Wahl der Dimensionen einzelner Blasen 14 und des Versandbehaelters 140 vorteilhaft, diese, unter Beruecksichtigung der zu verpackenden Gegenstaende, gegenseitig aufeinander abzustimmen. Eine maessige Toleranz kann hierbei durch Verminderung oder Erhoehung, der den Blasen 14 zugefuehrten Luftmenge, ausgeglichen werden. Waehrend das Objekt 142 von nur wenigen, verhaeltnismaessig langen Blasen 14 umgeben sein koennte , ist es , fuer empfindliche, oder sehr wertvolle Gegenstaende von Vorteil, die Verpackung in mehrere, kuerzere Blasen 14 aufzugliedern, um die Stabilitaet der Verpackung, fuer den Fall einer unvorhergesehenen Beschaedigung, aufrechtzuerhalten. Die verbliebenen Blasen 14 koennen hierbei, mit nur geringem Stabilitaetsverlust, das Fuellvolumen einer defekten Blase 14 ersetzen, verursacht, durch den Drang, unter Druck, ihre, unbelastet, zylindrische Form annehmen zu wollen.
In Figur 9 wird ein Objekt 143, in einem Versandbehaelter 144, von einer individuellen Blase 14 umschlossen, wobei die Blase 14 mit einer vorbestimmten Luftmenge gefuellt, an ihrem Durchlass 18, mittels des Stoepselfortsatzes 16 derselben Blase 14, luftdicht verschlossen ist. Die Blase 14 kann hierbei vor, waehrend, oder nach dem Einschieben beider Teile, in den Behaelter 144, gefuellt und verstoepselt werden.
Fuer den Verschluss einer letzten Blase 14, unter Anwendung mehrerer zusammengekuppelter Blasen 14, wird ein Stoepsel identisch mit Verschlusstoepsel 116, jedoch ohne Traeger 125 bereitgehalten.The figures show an interconnectable, inflatable packaging material and a method of its use, which in its basic structure consists of individual, flexible bladders 14, each with a closed end 22 and a partially closed end 24, a flexible, tubular material of any type large cross-section, closed at intervals of the desired bubble length, by fusion, gluing, or vulcanization 22, or partially closed 24, or bubbles 14/114 according to the invention, by means of molding, in a corresponding manner, or blown.
In a first embodiment of the invention, the partially closed end 24 of each bladder 14 is provided with a passage 18 having an attack bead 13 around its outer wall, and a radial groove 19 on its inner wall, and both the opening for filling and venting the bladder 14, as well as the receiver of the combined closure plug coupling according to the invention between two bladders 14. For this purpose, in the above-mentioned first embodiment, the closed end 22 of each bladder 14 is provided with a plug extension 16 which has an attack bead 15 and an annular radial spring 17. Both parts, both the passage 18 and the plug extension 16, are tapered in their connection area with the bladder ends 24/22, with the bladder skin 14a / 14b, in order to ensure the necessary elasticity for a rounded inflation of the bladders 14 at these transitions .
In use, a bladder 14, preferably with air, is filled to a desired pressure through its passage 18 and closed by means of the plug extension 16 of another bladder 14, or if a bladder 14 is used alone, its own plug extension 16. During the insertion of the plug extension 16 into a passage 18, the radial tongue 17 spreads the elastic wall thereof until it can snap into the radial groove 19. Thereupon, the elastic wall of the passage 18, relieved of the specified expansion, springs back into its fit in order to now close the plug extension 16 tightly and gas-tight.
For additional sealing, for example at higher pressure in a bladder 14, the tip of the plug extension 16 is tapered radially and forms a flexible lip 21 which is pressed against the inner wall of the passage 18 by a higher internal pressure within a bladder 14. The completed closure of a bladder 14 is achieved by latching the spring 17 into the groove 19, and at the same time the coupling of two bladders 14. This process can be repeated as often as desired with any number of bladders 14 in order to be able to produce any desired packaging volume. While the bubbles 14 can be of different sizes, the dimensions of Passage 18 and plug extension 16 advantageously held hand and machine, uniform.
In a second embodiment, the closed end 122 of a bladder 114 forms a tongue 123 which surrounds an eyelet 127. In this embodiment, the closure plug 116 is firmly connected to the passage 118 by means of a belt-like carrier 125. Two bubbles 114 are attached to one another by pushing the closure plug 116 into the eyelet 124, where it can be easily jammed by means of the conical shape and the groove 126. While this connection is sufficient for venting the bubbles 114 and rolling them up, after filling a bubble 114, the closure plug 116 is used in the passage 118, with the tongue 123 bent, into the passage 118 until the radial spring engages, in order to use the packaging material 117 pressed into the radial groove 119. The process of coupling together, after debugging, is largely spared with this embodiment, for venting and rewinding, as long as a number of packaging materials have been removed from one container. However, the bubbles 114 can, if required, be completely separated or replaced by loosening the closure plug 116 of a bubble 114, with little effort, from the eyelet 124 of another bubble 114. This embodiment also enables transport and storage of large usable volumes of packaging material in an economical, compact manner, since bubbles 114 can be rolled up into a roll 11, a relatively small volume, after ventilation.
The bladders 14/114, according to the invention, are made from a flexible, durable, airtight material such as vinyl or rubber. The wall thickness of the bladder skin 14a / 14b should be selected in use after its loading. Heavy objects require larger material thicknesses. The length and cross-sectional dimensions of the bladders 14/114 can also be determined in accordance with their intended use.
To protect the packaging material of the invention from sharp-edged or pointed object parts, various protective shields 130a-130d can be wrapped around an object 142 before packaging, which are preferably made of an unbreakable material such as nylon and are generally rounded on the outside. The particular application depends on the shape of one to be packaged Subject. An elastic tensioning band 131 is tensioned around the object after a protective shield 130a -130d has been attached.
For an application of the invention, a series of bubbles 14 are filled with air, while the passage 18 of each filled bubble 14 is closed with the plug extension 16, another bubble 14, and with continued filling and coupling, a chain of bubbles 14 is produced with which Help the bottom of a shipping container 140, lined in a zigzag pattern, until that bottom is covered. The end of the last uninflated bladder 14 used to close a bladder 14 advantageously hangs freely over the edge of the container 140. The object 142 is then placed, approximately in the middle, on the mat of bladders 14 produced, before the chain of bladders 14, continued with inflation and coupling, and this, along the lateral circumference of the object 142, is inserted between it and the wall of the container 140 until all sides of the object 142 are sufficiently padded. The chain of bubbles 14 is then expanded until, as illustrated in FIG. 8c, the object 142 is completely covered by covering in a zigzag pattern. The shipping container 140 is now ready to receive further items to be packaged or, when it is completely filled with it, to be closed.
When selecting the dimensions of individual bladders 14 and the shipping container 140, it is advantageous to coordinate them with one another, taking into account the objects to be packed. A moderate tolerance can be compensated by reducing or increasing the amount of air supplied to the bubbles 14. While the object 142 could be surrounded by only a few, relatively long bubbles 14, it is advantageous for sensitive or very valuable objects to divide the packaging into several, shorter bubbles 14 in order to ensure the stability of the packaging, in the event of an unforeseen event Damage to sustain. The remaining bubbles 14 can replace the filling volume of a defective bubble 14 with only a slight loss of stability, caused by the urge to take on their unloaded, cylindrical shape under pressure.
In FIG. 9, an object 143, in a shipping container 144, of enclosed in an individual bladder 14, the bladder 14 being filled with a predetermined amount of air and being airtight at its passage 18 by means of the plug extension 16 of the same bladder 14. The bladder 14 can be filled and blocked before, during or after the insertion of both parts into the container 144.
For the closure of a last bubble 14, using a plurality of bubbles 14 coupled together, a stopper identical to closure stopper 116, but without carrier 125, is kept ready.
