Description

Der Gegenstand der Erfindung betrifft eine Halteplatte aus Kunststoff oder dergl. für Staubsaugerfilterbeutel, wobei die Halteplatte eine Öffnung für den Sauganschlußstutzen des Staubsaugers aufweist und für den Saugbetrieb mit dem Staubsaugerfilterbeutel in eine Plattenaufnahme des Staubsaugers formschlüssig einsteckbar ist.The object of the invention relates to a holding plate made of plastic or the like. For vacuum cleaner filter bags, the holding plate having an opening for the suction connection piece of the vacuum cleaner and for the suction operation with the vacuum cleaner filter bag can be positively inserted into a plate receptacle of the vacuum cleaner.

Eine derartige Halteplatte ist aus der DE-OS 21 16 579 bekannt.Such a holding plate is known from DE-OS 21 16 579.

Bei der bekannten Halteplatte ist zur staubdichten Verbindung der den Filterbeutel tragenden Halteplatte mit dem Sauganschlußstutzen des Staubsaugers die Öffnung für den Sauganschlußstutzen mit einer angeformten elastischen, umlaufenden Dichtlippe versehen, die mit der Halteplatte einstückig ausgebildet ist. Das übrige Plattenmaterial der Halteplatte ist äußerst biegesteif, um die Halteplatte und damit den Staubfilterbeutel in der zugeordneten Plattenaufnahme des Staubsaugers, welche zumindest einen Begrenzungsrand der Halteplatte im eingesteckten Zustand formschlüssig umgreift, sicher zu halten. Die Dichtwirkung einer derart ausgebildeten Halteplatte ist für solche Staubsauger optimal, bei denen die Halteplatte zur staubdichten Verbindung mit dem Staubsauger direkt auf den gegenüber der Öffnung in der Halteplatte im Durchmesser größeren Sauganschlußstutzen geschoben wird, wobei sich die elastische umlaufende Dichtlippe im Öffnungsbereich der Platte staubdicht um den Sauganschlußstutzen legt. Bei den Staubsaugern der vorgenannten Verbindungsart einer Halteplatte ist der Sauganschlußstutzen in der Regel am Staubsaugergehäuse angeordnet und bis in den Staubsammelraum des Staubsaugers geführt. Das Aufschieben der Halteplatte auf den Sauganschlußstutzen erfolgt dabei manuell.In the known holding plate for the dust-tight connection of the holding plate carrying the filter bag to the suction connection piece of the vacuum cleaner, the opening for the suction connection piece is provided with an integrally formed elastic, circumferential sealing lip which is formed in one piece with the holding plate. The remaining plate material of the holding plate is extremely rigid in order to hold the holding plate and thus the dust filter bag securely in the associated plate receptacle of the vacuum cleaner, which positively engages around at least one boundary edge of the holding plate when inserted. The sealing effect of a holding plate designed in this way is optimal for those vacuum cleaners in which the holding plate for the dust-tight connection with the vacuum cleaner is pushed directly onto the suction connection piece which is larger in diameter than the opening in the holding plate, the elastic circumferential sealing lip being dust-tight around the opening area of the plate puts the suction connector. In the case of the vacuum cleaners of the aforementioned type of connection of a holding plate, the suction connection piece is generally arranged on the vacuum cleaner housing and is guided into the dust collection space of the vacuum cleaner. The holding plate is pushed onto the suction connection piece manually.

Bei sehr vielen derzeit auf dem Markt befindlichen Staubsaugertypen nimmt jedoch der den Staubbeutelsammelraum verschließende und schwenkbar am Staubsaugergehäuse angelenkte Deckel zugleich den Sauganschlußstutzen des Staubsaugers auf, während die Halteplatte separat hiervon mit dem Staubsaugerfilterbeutel in einer ggf. schwenkbar im Staubsammelraum gelagerten Plattenaufnahme formschlüssig eingesteckt ist. Bei diesen Staubsaugern erfolgt die Verbindung zwischen dem Sauganschlußstutzen und der Halteplatte selbsttätig beim Schließen des Deckels. Wird der Deckel geschlossen, so schwenkt der Sauganschlußstutzen ggf. zentrierend in die Öffnung der Halteplatte ein. Die geforderte Abdichtung zwischen der Halteplatte und dem Sauganschlußstutzen bewerkstelligt dabei ein den Sauganschlußstutzen umgebender Dichtansatz am Deckel des Staubsaugers, welcher bei geschlossenem Deckel die Einlaßöffnung an der Halteplattenoberseite ringförmig umgreift und in Auflage damit steht. Bei diesen Staubsaugern ist es auch üblich, den Sauganschlußstutzen am Dichtansatz enden zu lassen, so daß der Stutzen nicht in die Öffnung der Halteplatte eingreifen kann.In the case of many types of vacuum cleaner currently on the market, however, the cover which closes the dust bag collecting space and which is pivotably articulated on the vacuum cleaner housing also accommodates the suction connection piece of the vacuum cleaner, while the holding plate is inserted in a form-fitting manner with the vacuum cleaner filter bag in a plate receptacle, which may be pivoted in the dust collecting space. In these vacuum cleaners, the connection between the suction connection piece and the holding plate takes place automatically when the lid is closed. If the lid is closed, the suction connection piece swivels centering into the opening of the holding plate, if necessary. The required seal between the holding plate and the suction connection piece is accomplished by a sealing attachment on the cover of the vacuum cleaner surrounding the suction connection piece, which, when the cover is closed, encompasses the inlet opening on the upper side of the holding plate and is in contact with it. With these vacuum cleaners, it is also common to let the suction connection piece end at the sealing attachment, so that the piece cannot engage in the opening of the holding plate.

Die bekannte Halteplatte kann für die letztgenannten Staubsaugertypen zu Problemen führen. Infolge der sich beim Schließen des Staubraumdeckels ergebenden Relativbewegungen zwischen der Halteplatte und dem Sauganschluß im Deckel, die eine genaue Zentrierung der miteinander zu verbindenden Teile erforderlich machen, sind sehr enge Maßtoleranzen sowohl bei der Halteplatte als auch bei den sonstigen mit dem Staubfilterbeutel in Wirkverbindung stehenden Funktionsteilen, wie Deckellagerung, Anordnung des Sauganschlußstutzens am Deckel oder dergl. einzuhalten, damit bei geschlossenem Deckel die optimale Dichtwirkung erzielt wird. Voraussetzung hierfür ist jedoch, daß ein gleichmäßiger Anpreßdruck in der Randzone der öffnung auf der Halteplatte zwischen dem Sauganschluß und der Halteplatte erreicht wird. Dies ist aber z. B. schon bei leicht gewölbten Halteplatten nicht mehr gegeben, da sich das biegesteife Plattenmaterial im Bereich der öffnung für den Sauganschluß den Formänderungen bzw. Plattenverwerfungen nicht selbständig anpassen kann. Die Verbindung zwischen dem Sauganschluß und der mit diesem bei geschlossenem Staubraumdeckel in Berührung stehenden Halteplatte kann undicht werden, da ein ungleichmäßig verteilter Anpreßdruck herrscht. Dieser Nachteil tritt ebenfalls ein, wenn sich z. B. durch Unregelmäßigkeiten im Plattenmaterial unterschiedliche Plattenstärken ergeben. Somit kann ungefilterte, staubbeladene Luft in den Motorgebläseraum gelangen, mit den Folgen, daß der Gebläsemotor u. Umständen beschädigt oder gar zerstört wird. Ebenso kann eine Undichtheit zwischen dem Sauganschluß und der mit diesem bei geschlossenm Deckel in Anlage gebrachten Halteplatte auch eintreten, wenn die Plattenaufnahme bzw. die Halteplatte selbst nicht lagerichtig im Staubsauger eingesetzt ist. Ist beispielsweise der Schwenkweg der Plattenaufnahme zu gering, so verbleibt ein keilförmiger Spalt zwischen der Halteplattenoberfläche und dem zugeordneten Dichtansatz am Sauganschluß, durch den ebenfalls ein staubbeladener den Staubsaugerfilterbeutel umgehender Saugluftstrom mit entsprechend nachteiliger Wirkung entsteht.The known holding plate can lead to problems for the latter types of vacuum cleaner. As a result of the relative movements between the holding plate and the suction connection in the lid that occur when the dust chamber lid is closed, which necessitate precise centering of the parts to be connected to one another, there are very narrow dimensional tolerances both for the holding plate and for the other functional parts that are operatively connected to the dust filter bag , such as lid storage, arrangement of the suction connector on the lid or the like. To ensure that the optimum sealing effect is achieved when the lid is closed. The prerequisite for this, however, is that a uniform contact pressure is achieved in the edge zone of the opening on the holding plate between the suction connection and the holding plate. But this is e.g. B. is no longer given even with slightly arched holding plates, since the rigid plate material in the area of the opening for the suction connection cannot adapt to the shape changes or plate warpage independently. The connection between the suction connection and the holding plate which is in contact with it when the dust chamber cover is closed can become leaky, since there is an unevenly distributed contact pressure. This disadvantage also occurs when z. B. result from irregularities in the plate material different plate thicknesses. Thus, unfiltered, dust-laden air can get into the engine blower compartment, with the result that the blower motor u. Is damaged or even destroyed. Likewise, a leak between the suction connection and the holding plate brought into contact with the latter with the cover closed can also occur if the plate holder or the holding plate itself is not inserted in the correct position in the vacuum cleaner. If, for example, the swivel path of the plate holder is too short, a wedge-shaped gap remains between the holding plate surface and the associated sealing attachment on the suction connection, which also creates a dust-laden suction air flow bypassing the vacuum cleaner filter bag with a correspondingly disadvantageous effect.

Der Erfindung liegt somit die Aufgabe zugrunde, eine biegesteife Halteplatte der eingangs genannten Art so auszubilden, daß sie im Bereich der öffnung für den Sauganschluß elastischer wird und daß auch bei abweichenden Maßtoleranzen der mit dem Staubsaugerfilterbeutel in Wirkverbindung stehenden Funktionsteile sowie bei Unregelmäßigkeiten im Plattenmaterial oder auf der Oberfläche der Halteplatte selbst eine optimale Staubabdichtung zwischen dem Sauganschluß des Staubsaugers und der Halteplatte erreicht wird.The invention is therefore based on the object of forming a rigid holding plate of the type mentioned in such a way that it becomes more elastic in the area of the opening for the suction connection and that even in the case of deviating dimensional tolerances of the functional parts which are operatively connected to the vacuum cleaner filter bag and in the event of irregularities in the plate material or the surface of the holding plate itself an optimal dust seal between the suction port of the vacuum cleaner and the holding plate is achieved.

Die gestellte Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des Kennzeichens des Anspruches 1.The object is achieved according to the invention by the features of the characterizing part of claim 1.

Vorteilhafte Ausgestaltungen gehen aus den Unteransprüchen hervor.Advantageous configurations emerge from the subclaims.

Die mit der Erfindung erzielten Vorteile sind insbesondere darin zu sehen, daß sich die Halteplatte in der Plattenaufnahme des Staubsaugers beim Schließen des Staubraumdeckels schon bei der ersten Berührung mit dem Sauganschluß selbsttätig den auf sie wirkenden Belastungen anpaßt und bei geschlossenem Deckel absolut dicht mit dem rundum gleichmäßig belasteten Sauganschluß abschließt. Durch die besondere Anordnung der Elastizitätszonen auf der Halteplatte ist gewährleistet, daß keine engen Maßtoleranzen zwischen den Funktionsteilen eingehalten werden müssen. Trotz des biegesteifen Plattenmaterials wird erreicht, daß die Halteplatte selbstdichtend wirkt, weil die Dichtwirkung zwischen der erfindungsgemäß sehr elastischen Halteplattenfläche im Bereich der öffnung und dem darüberliegenden Sauganschluß erzielt wird.The advantages achieved by the invention can be seen in particular in the fact that the holding plate in the plate receptacle of the vacuum cleaner automatically adapts to the stresses acting on it when the dust chamber cover is first touched, and when the cover is closed it is absolutely tight with all around loads the suction connection. The special arrangement of the elastic zones on the holding plate ensures that there are no tight dimensional tolerances between the functional parts. Despite the rigid plate material, it is achieved that the holding plate acts self-sealing because the sealing effect between the very elastic holding plate surface according to the invention in the loading range of the opening and the suction connection above it is achieved.

Durch die Erfindung werden Zonen unterschiedlicher Elastizität auf der Halteplatte ohne Änderung der Werkstoffkomponenten bzw. ohne Änderung der Materialstärke geschaffen. Die Elastizitätszonen in Form von Plattenausschnitten sind werkzeugmäßig einfach zu realisieren und stellen z. B. bei aus thermoplastischem Kunststoff gefertigten Halteplatten keinerlei Probleme beim Spritzen dar. Ferner wird durch die Verwendung von Plattenausschnitten als Elastizitätszonen wesentlich weniger Material zur Plattenherstellung benötigt als bisher, so daß die Halteplatten auch kostengünstiger werden.The invention creates zones of different elasticity on the holding plate without changing the material components or without changing the material thickness. The elasticity zones in the form of panel cutouts are easy to implement using tools and represent e.g. B. in thermoplastic plastic holding plates no problems with spraying. Furthermore, the use of plate cutouts as zones of elasticity requires much less material for plate production than before, so that the holding plates are also less expensive.

Bei dem in Fig. 1 dargestellten Staubsauger 1 vom Typ eines Bodenstaubsaugers ist bei geöffnetem Staubraumdeckel 2, welcher am Staubsaugergehäuse schwenkbar angelenkt ist, der Staubsammelraum 3 zugänglich. Der Staubsammelraum 3 dient zur Aufnahme des Staubsaugerfilterbeutels 4.In the vacuum cleaner 1 of the floor vacuum cleaner type shown in FIG. 1, the dust collecting space 3 is accessible when the dust chamber cover 2 is open, which is pivotably articulated on the vacuum cleaner housing. The dust collecting space 3 serves to hold the vacuum cleaner filter bag 4.

Der Staubsaugerfilterbeutel 4 ist über eine vorzugsweise aus einem thermoplastischen Kunststoff bestehende biegesteife Halteplatte 5 in einer Plattenaufnahme 6 im Staubsammelraum 3 lösbar befestigt. Die Verbindung zwischen der Halteplatte 5 und dem Staubsaugerfilterbeutel 4 kann beispielsweise über eine Klebeverbindung oder auch über eine Schweißverbindung hergestellt werden. Hierzu weist die Halteplatte eine kreisförmige Befestigungszone 7 (Fig. 2 u. 3) auf.The vacuum cleaner filter bag 4 is detachably fastened in a plate receptacle 6 in the dust collecting space 3 via a rigid holding plate 5 preferably made of a thermoplastic plastic. The connection between the holding plate 5 and the vacuum cleaner filter bag 4 can be established, for example, via an adhesive connection or also via a welded connection. For this purpose, the holding plate has a circular fastening zone 7 (FIGS. 2 and 3).

Die Halteplatte 5 ist in bekannter Weise formschlüssig in die Plattenaufnahme 6 einzustecken, welche dann den unteren sowie jeweils einen seitlichen Begrenzungsrand 8 (Fig. 2) der Halteplatte 5 nach Art einer anschlagbegrenzten Führung umgreift. Die Plattenaufnahme 6 selbst ist anschlagbegrenzt schwenkbar im Staubsaugergehäuse gelagert.The holding plate 5 is to be positively inserted into the plate receptacle 6 in a known manner, which then engages around the lower and one lateral boundary edge 8 (FIG. 2) of the holding plate 5 in the manner of a stop-limited guide. The plate receptacle 6 itself is pivotally limited in the vacuum cleaner housing.

Die Halteplatte 5 weist mittig eine Öffnung 9 mit einer umlaufenden Dichtlippe 10 für einen im Staubraumdeckel 2 angeordneten Sauganschlußstutzen 11 auf, dessen Öffnung von einem Dichtansatz 12 für die Halteplatte 5 in ebenfalls bekannter Weise umgeben ist.The holding plate 5 has an opening 9 in the middle with a circumferential sealing lip 10 for a suction connection piece 11 arranged in the dust chamber cover 2, the opening of which is surrounded by a sealing attachment 12 for the holding plate 5 in a likewise known manner.

Die Anordnung des Sauganschlußstutzens 11 im Staubraumdeckel 2 ist so gewählt, daß bei geschlossenem Staubraumdeckel 2 die Öffnung 9 in der eingesteckten Halteplatte 5 deckungsgleich der Sauganschlußstutzenöffnung gegenübersteht, wobei die Dichtwirkung zwischen dem Sauganschlußstutzen 11 und der Halteplatte durch den Anpreßdruck des Deckels bzw. des Dichtansatzes 12 des Sauganschlußstutzens 11 auf die Halteplatte 5 erzielt wird.The arrangement of the suction connector 11 in the dust chamber cover 2 is chosen so that when the dust chamber cover 2 is closed, the opening 9 in the inserted holding plate 5 is congruent faces the suction port opening, the sealing effect between the suction port 11 and the holding plate being achieved by the contact pressure of the cover or the sealing projection 12 of the suction port 11 on the holding plate 5.

Um zu gewährleisten, daß diese Verbindung bei geschlossenem Staubraumdeckel 2 absolut staubdicht hergestellt wird, weist die Halteplatte 5 im biegesteifen Plattenmaterial ein oder mehrere Elastizitätszonen 13 auf. Die Elastizitätszonen 13 sind dabei auf der Halteplatte 5 außerhalb der Befestigungszone 7 zwischen der Öffnung 9 für den Sauganschlußstutzen 11 und mindestens einem Begrenzungsrand 8 der Halteplatte 5 angeordnet. Durch diese Elastizitätszonen 13, die in Form von Plattenausschnitten realisiert sind, wird die biegesteife Halteplatte 5 im Plattenbereich um die Öffnung 9 herum wesentlich elastischer als die übrige Plattenfläche, so daß der Öffnungsbereich der Halteplatte 5 bei geschlossenem Staubraumdeckel 2 und unterstützt durch einen gleichmäßig im Öffnungsbereich wirkenden Anpreßdruck des Sauganschlußstutzens 11 bzw. des Dichtansatzes 12 selbstdichtend mit dem Sauganschluß in Wirkverbindung tritt, so daß Undichtheiten oder Nebenluftwege vollkommen ausgeschaltet werden. Die konzentrisch zur Öffnung 9 auf der Halteplatte 5 angeordnete Dichtlippe 10 unterstützt dabei die Dichtwirkung zusätzlich.In order to ensure that this connection is made absolutely dust-tight when the dust chamber cover 2 is closed, the holding plate 5 has one or more elastic zones 13 in the rigid plate material. The elastic zones 13 are arranged on the holding plate 5 outside the fastening zone 7 between the opening 9 for the suction connection piece 11 and at least one boundary edge 8 of the holding plate 5. Through these elastic zones 13, which are realized in the form of plate cutouts, the rigid holding plate 5 in the plate area around the opening 9 is substantially more elastic than the rest of the plate surface, so that the opening area of the holding plate 5 with the dust chamber cover 2 closed and supported by a uniformly in the opening area effective contact pressure of the suction connection piece 11 or the sealing attachment 12 self-sealingly comes into operative connection with the suction connection, so that leaks or secondary air passages are completely eliminated. The sealing lip 10 arranged concentrically to the opening 9 on the holding plate 5 additionally supports the sealing effect.

Nach der Erfindung sind nunmehr mehrere Varianten bezüglich der Ausbildung und Anordnung der Elastizitätszonen 13 möglich.According to the invention, several variants with regard to the design and arrangement of the elastic zones 13 are now possible.

Nach Fig. 2 ist beispielsweise eine Ausführung gewählt (siehe auch Fig. 3), bei der die in Form von Plattenausschnitten ausgebildeten Elastizitätszonen 13 gradlinig verlaufend auf der Halteplatte 5 angeordnet sind und jeweils am unteren Begrenzungsrand 8 der Halteplatte 5 in Platteneinsteckrichtung gesehen offen enden. Die Abbildung zeigt dabei zwei Elastizitätszonen 13 beiderseits der Öffnung 9 für den Sauganschlußstutzen 11, denen zweckmäßigerweise in der Plattenaufnahme 6 (Fig. 8) des Staubsaugers 1 angepaßte Gegenstücke 14 in Form von Stegen oder dergl. zugeordnet sind. Bei-dem hier gezeigten Ausführungsbeispiel bewirken die z. B. angeformten Gegenstücke 14 eine vorteilhafte Versteifung der Plattenaufnahme 6, insbesondere eine Verstärkung der Halteplatten-Führungen dieser Plattenaufnahme.According to FIG. 2, for example, an embodiment is selected (see also FIG. 3) in which the elastic zones 13 in the form of plate cutouts are arranged in a straight line on the holding plate 5 and each at the lower boundary edge 8 of the holding plate 5, seen in the plate insertion direction, end openly. The figure shows two elastic zones 13 on both sides of the opening 9 for the suction connection piece 11, to which counterparts 14 in the form of webs or the like are expediently assigned in the plate receptacle 6 (FIG. 8) of the vacuum cleaner 1. In the embodiment shown here, the z. B. molded counterparts 14 an advantageous stiffening of the plate holder 6, in particular a reinforcement of the holding plate guides of this plate holder.

Die Ausführung der Halteplatte 5 entsprechend Fig. 2 ist schon in vielen Fällen ausreichend, um der Platte die erforderliche Elastizität zu geben. Insbesondere ist die gewählte Anordnung der Elastizitätszonen 13 sehr gut geeignet, die Fluchtungsfehler in der Schwenkebene des Staubraumdeckels 2 zwischen der Halteplatte 5 und dem Deckel mit dem Sauganschlußstutzen 11 zu kompensieren.2 is sufficient in many cases to give the plate the required elasticity. In particular, the selected arrangement of the elasticity zones 13 is very well suited to compensating for the misalignment in the swivel plane of the dust chamber cover 2 between the holding plate 5 and the cover with the suction connection piece 11.

Beim Ausführungsbeispiel gemäß Fig. 4 sind ebenfalls zwei Elastizitätszonen 13 vorgesehen, von denen die eine am oberen Begrenzungsrand 8 und die andere am unteren Begrenzungsrand 8 offen endet. Die Elastizitätszonen 13 verlaufen ebenfalls gerade und sind auf das Zentrum der Öffnung9 für den Sauganschlußstutzen 11 zentriert.In the embodiment according to FIG. 4, two elastic zones 13 are also provided, one of which ends openly at the upper boundary edge 8 and the other at the lower boundary edge 8. The elastic zones 13 also run straight and are centered on the center of the opening 9 for the suction connection piece 11.

In den Fig. 5 bis 7 hingegen sind Halteplatten 5 gezeigt, bei denen die Elastizitätszonen 13 nicht bis direkt an die Plattenränder reichen. Dabei sind entsprechend Fig. 5 jeweils rechts und links der Öffnung 9 Plattenausschnitte als Elastizitätszonen 13 und gemäß Fig. 6 diagonal auf der Halteplatte 5 verlaufende Ausschnitte vorgesehen.5 to 7, on the other hand, holding plates 5 are shown, in which the elastic zones 13 do not extend directly to the plate edges. 5, plate cutouts are provided as elasticity zones 13 on the right and left of the opening, and cutouts running diagonally on the holding plate 5 according to FIG. 6.

Nach Fig. 7 sind die Elastizitätszonen 13 konzentrisch zur Öffnung des Sauganschlußstutzens 11 vorgesehen.7, the elastic zones 13 are provided concentrically to the opening of the suction connection piece 11.

Wie insbesondere aus Fig. 5 ersichtlich, kann sich die Halteplatte 5 bei fest eingespanntem Begrenzungsrand 8 in der Plattenaufnahme 6 und selbst bei einem Fluchtungsfehler zwischen ihr und der Plattenaufnahme 6 im Bereich der Öffnung 9 dem Sauganschlußstutzen 11 staubdicht anpassen. Dabei herrscht praktisch überall der gleiche Anpreßdruck auf der Plattenoberfläche im Bereich der Öffnung 9, so daß die Staubdichtheit immer gewährleistet ist.As can be seen in particular from FIG. 5, the holding plate 5 can adapt to the suction connector 11 in a dust-tight manner when the boundary edge 8 is firmly clamped in the plate receptacle 6 and even in the event of an alignment error between it and the plate receptacle 6 in the region of the opening 9. The same contact pressure prevails practically everywhere on the plate surface in the area of the opening 9, so that dust-tightness is always guaranteed.

Abweichend von den hier beschriebenen Ausführungsbeispielen sind selbstverständlich weitere Gestaltungsmöglichkeiten der Elastizitätszonen 13 auf der Halteplatte 5 denkbar und möglich. Auch könnte die Halteplatte 5 statt aus Kunststoff aus Pappe gefertigt sein.In a departure from the exemplary embodiments described here, further design options for the elasticity zones 13 on the holding plate 5 are of course conceivable and possible. The holding plate 5 could also be made of cardboard instead of plastic.
