Description

Die Erfindung betrifft einen Reinigungsmittelbehälter oder dergleichen, mit einem Schmelzverschluß, welcher aus einem in einem Verschlußloch des Behälters, insbesondere in dessen Deckel, befindlichen Stopfen aus bei vorgegebener Temperatur schmelzendem und das Verschlußloch für den Austritt von im Behälter befindlichem Produkt freigegebenem Material, vorzugsweise aus Paraffin, besteht, wobei an die Umfangsfläche des Verschlußlochs ein in Richtung auf die Achse des Verschlußlochs erhabener Ring zum Festhalten des noch ungeschmolzenen Stopfens angeformt ist.The invention relates to a detergent container or the like, with a melt closure, which consists of a stopper located in a closure hole of the container, in particular in the lid, of melting at a predetermined temperature and the closure hole for the release of product located in the container, preferably of paraffin , There is, on the circumferential surface of the closure hole, a raised ring in the direction of the axis of the closure hole for holding the still unmelted plug is formed.

Flüssigkeitsdichte Schmelzverschlüsse werden bei Produktbehältern eingesetzt, die in einem geschlossenen Raum während eines Verfahrensablaufs bei einer bestimmten Temperatur geöffnet werden sollen. Beispielsweise werden Behälter mit SchmelzverschluB zur Aufnahme von in Spülmaschinen einzusetzenden Maschinenpflegern verwendet. In diesem Fall wird der ungeöffnete Behälter in den Maschinenraum eingebracht. Daraufhin wird die Maschine nach Schließen des Maschinenraums in Gang gesetzt. Um zu vermeiden, daß das zum Pflegen der Maschine vorgesehene Produkt vorzeitig aus dem Behälter austritt, wird das Material des Schmelzverschlusses so ausgewählt, daß der fragliche Stopfen erst bei der für die Anwendung des Produkts günstigsten Temperatur schmilzt, das Produkt also erst in diesem Moment in den Maschinenraum eintritt. Der Stopfen darf auch nicht ohne zu schmelzen, aus seiner Lage im Verschlußloch des Behälters herausgleiten können, daher wurde an die Umfangsfläche des Verschlußlochs ein in Richtung auf die Lochachse vorspringender Wulst zum Festhalten des Stopfens ringförmig umlaufend angeformt.Liquid-tight fuses are used for product containers that are to be opened in a closed room during a process sequence at a certain temperature. For example, containers with a melt closure are used to hold machine cleaners to be used in dishwashers. In this case, the unopened container is placed in the machine room. The machine is then started after the machine room is closed. In order to avoid that the product intended for the maintenance of the machine comes out of the container prematurely, the material of the melt closure is selected in such a way that the stopper in question only melts at the temperature that is most favorable for the use of the product, i.e. the product only at this moment enters the machine room. The plug must not melt without it, from its position in the sealing hole of the loading can slide out, therefore a bulge projecting in the direction of the hole axis was formed on the circumferential surface of the closure hole in order to hold the plug in a circular manner.

Bei Lagerung von verschlossenen Produktbehältern vorgenannter Art kann es, j in Folge von Temperaturschwankungen, zu einem unerwünschten Kriechen des Produkts zwischen der Umfangsfläche des Verschlußlochs und dem Stopfen kommen. Dieser Effekt tritt besonders bei stark benetzendem, kriechfreudigem Produkt auf. Eine Ursache für den Produktaustritt besteht darin, daß durch Temperaturschwankungen winzige Spalte zwischen der Wandung bzw. Umfangsfläche des Verschlußlochs und dem darin eingesetzten, insbesondere eingegossenen, Schmelz-Stopfen entstehen, durch die das Produkt, gegebenenfalls über den Wulst hinweg, hindurchwandern kann.When sealed product containers of the aforementioned type are stored, j as a result of temperature fluctuations can lead to undesirable creeping of the product between the peripheral surface of the sealing hole and the stopper. This effect occurs particularly in the case of a strongly wetting, creep-friendly product. One reason for the product leakage is that, due to temperature fluctuations, tiny gaps are formed between the wall or circumferential surface of the closure hole and the melting plug, in particular poured into it, through which the product can pass, possibly over the bead.

Dieses Problem könnte durch Angleichen der TemperaturAusdehnungskoeffizienten der im Stopfenbereich aneinander grenzenden Materialien behoben werden. Da jedoch die Materialauswahl für den Behälter und den Schmelzverschluß bereits durch eine Vielzahl anderer Forderungen, z.B. nach Temperaturbeständigkeit bzw. Schmelzpunkt, mechanische Beständigkeit, chemische Beständigkeit und dergleichen, bestimmt wird, kann bei Anpassung der Ausdehnungskoeffizienten immer nur ein mehr oder weniger akzeptabler Kompromiß geschlossen werden.This problem could be solved by adjusting the temperature expansion coefficients of the materials adjacent to each other in the stopper area. However, since the choice of material for the container and the fuse closure is already determined by a variety of other requirements, e.g. after temperature resistance or melting point, mechanical resistance, chemical resistance and the like, is determined, only a more or less acceptable compromise can be made when adjusting the expansion coefficient.

Wenn nach dem Vorangehenden ein durch den Schmelzverschluß gut abgedichteter Produktbehälter erhalten wird, ist bei durch Temperaturerhöhung gasenden Produkten unterhalb der Schmelztemperatur des Stopfens, mit Überdruck im Behälterinnern zu rechnen. Gegebenenfalls wirkt der Überdruck auch auf den Stopfen. Das Material des Stopfens ist bei erhöhter Temperatur in der Regel schon relativ weich, da es bei weiterer Temperaturerhöhung schmelzen soll. Es kann etwa bei starken Temperaturschwankungen (z. B. Tag/Nacht) der Fall eintreten, daß der Stopfen durch wechselnden über- und Unterdruck wie eine Pumpe wirkt und an der Innenfläche anhaftendes Produkt nach außen befördert.If, according to the foregoing, a product container which is well sealed by the melt seal is obtained, an overpressure in the interior of the container is to be expected in the case of products gassing due to an increase in temperature below the melting temperature of the stopper. If necessary, the Overpressure also on the stopper. The material of the stopper is usually already relatively soft at elevated temperature, since it is intended to melt as the temperature increases further. For example, in the case of strong temperature fluctuations (e.g. day / night), the stopper acts like a pump due to changing overpressure and underpressure and transports product adhering to the inner surface to the outside.

Der Erfindung liegt allgemein die Aufgabe zugrunde, eine das vorzeitige Austreten des im Behälter befindlichen Produkts verhindernde Abdichtung zu schaffen, die auch bei unterschiedlichem Temperatur-Ausdehnungsverhalten von Behälter- bzw. Deckelwandung einerseits und dem im Verschlußloch des Behälters befindlichen Stopfen andererseits wirksam ist. Insbesondere soll verhindert werden, daß der Stopfen durch temperaturbedingte Änderung des Behälterinnendrucks in seiner Lage relativ zum Verschlußloch verändert werden kann.The invention is generally based on the object to provide a premature leakage of the product located in the container seal, which is effective even with different temperature expansion behavior of the container or lid wall on the one hand and the plug located in the closure hole of the container on the other hand. In particular, it should be prevented that the stopper can be changed in its position relative to the closure hole by changing the internal pressure of the container due to temperature.

Für den eingangs genannten Reinigungsmittelbehälter und dergleichen mit einem in einem Verschlußloch vorgesehenen stopfenförmigen Schmelzverschluß und mit einem an die Umfangsfläche des Verschlußlochs in Richtung auf die Lochachse angeformten, erhabenem Ring besteht die erfindungsgemäße Lösung darin, daß der Ring im Verlaufe seiner radialen Erstreckung von der Umfangsfläche radial nach innen in Richtung auf die Lochachse eine Dickenzunahme aufweist.For the cleaning agent container and the like mentioned at the outset with a plug-shaped melt closure provided in a closure hole and with a raised ring molded onto the circumferential surface of the closure hole in the direction of the hole axis, the solution according to the invention consists in that the ring radially extends radially from the circumferential surface in the course of its radial extension has an increase in thickness in the direction of the hole axis.

Vorzugsweise soll der Ring eine zu der senkrecht zur Lochachse etwa durch die Lochmitte gehenden Ebene spiegelsymmetrische Dickenzunahme besitzen. Insbesondere kommt ein Ring mit Schwalbenschwanz-Profil oder mit T-Profil in Frage.The ring should preferably play a plane perpendicular to the hole axis, approximately through the center of the hole have a symmetrical increase in thickness. In particular, a ring with a dovetail profile or a T-profile can be used.

Gemäß weiterer Erfindung können zum Stabilisieren des Verschlußstopfens gegenüber temperaturbedingten Druckänderungen des Behälterinnern folgende Maßnahmen vorgesehen werden: Zunächst kann der Verschlußstopfen selbst dadurch stabilisiert werden, daß auf der Außenseite des Behälters, insbesondere des Deckels, um das Verschlußloch herum eine ringförmige Erhöhung zum besonders sicheren Aufsiegeln einer Verschlußfolie vorgesehen wird. Außerdem wird die das Verschlußloch auf der Behälteraußenseite abdeckende Folie besonders stabil, wenn sie aus mit Polypropylenlack beschichtetem, fein geprägtem Aluminium, insbesondere mit einer Dicke von etwa 40 Mikrometern, besteht. Wenn die Folie mit einer frei stehenden Lasche ausgestattet wird, läßt sie sich vor Einsatz leicht abziehen.According to another invention, the following measures can be provided to stabilize the sealing plug against temperature-related pressure changes in the interior of the container: First, the sealing plug itself can be stabilized in that on the outside of the container, in particular the lid, around the sealing hole, an annular elevation for particularly securely sealing one Closure film is provided. In addition, the film covering the closure hole on the outside of the container becomes particularly stable if it consists of finely embossed aluminum coated with polypropylene lacquer, in particular with a thickness of approximately 40 micrometers. If the film is equipped with a free-standing tab, it can be easily removed before use.

Zusätzlich zu den Maßnahmen zum Stabilisieren des Stopfens mittels der Siegelfolie kann es auch günstig sein, den Produktbehälter bei Ausbildung als Polyäthylenflasche, vorzugsweise mit Viereckquerschnitt, so auszulegen, daß bei einer vorgegebenen Stapelhöhe eine noch ausreichende Stauchlast erreicht wird und daß zugleich die Wandungen so nachgiebig bleiben, daß der Dampfdruck des Behälterinhalts bei zeitweise auftretenden höheren Außentemperaturen ansteigen kann, ohne den relativ weichen Stopfen in der Form oder Position störend zu beeinträchtigen. Vorzugsweise soll hiernach die Wandstärke im Bereich zwischen einem der vorgegebenen Stapelhöhe entsprechenden Mindestwert, insbesondere von wenigstens etwa 0,7 mm, einerseits und einem ein elastisches Dehnen und Schrumpfen bei temperaturbedingter Druckänderung, insbesondere von mindestens etwa 0,05 bar, im Behälterinnern zulassenden Maximalwert andererseits liegen.In addition to the measures to stabilize the stopper by means of the sealing film, it can also be advantageous to design the product container when it is designed as a polyethylene bottle, preferably with a square cross-section, in such a way that a sufficient compression load is achieved at a predetermined stack height and that the walls remain so compliant at the same time that the vapor pressure of the container contents can rise at occasionally higher outside temperatures without interfering with the relatively soft stopper in the shape or position. According to this, the wall thickness should preferably be on the one hand and in the range between a minimum value corresponding to the predetermined stack height, in particular of at least about 0.7 mm on the other hand, there is an elastic stretching and shrinking in the case of a pressure change due to temperature, in particular of at least about 0.05 bar, in the maximum value inside the container.

Im übrigen wird durch die erfindungsgemäße Ausbildung der inneren Umfangsfläche des Verschlußlochs - also des vollständig von dem zu schmelzenden Stopfenmaterial umgebenden Ringprofils - erreicht, daß sich ein relativ zum Behältermaterial schrumpfender Schmelzverschluß bei dem Schrumpfen sogar enger an den Ring anschließt als ursprünglich beim Eingießen in das Verschlußloch. Wenn der Querschnitt des Rings von der Umfangsfläche des Verschlußlochs in Richtung auf die Lochachse in erfindungsgemäßer Weise zunimmt, ergibt sich auch bei relativ zum Material der Verschlußlochwand geschrumpften Stopfen ein vollkommen dichter Verschluß, der - gegebenenfalls bei Vermeidung übermäßiger Druckeinwirkung - erst durch Abschmelzen des Stopfens zu öffnen ist. Dieser Vorteil wird noch dadurch verstärkt, daß der Weg, den das in dem Behälter befindliche Produkt - am Stopfen vorbei - zurücklegen müßte, um aus dem Behälter zu gelangen, durch die erfindungsgemäße Form des Rings labyrinthartig vergrößert wird.Incidentally, the inventive design of the inner circumferential surface of the closure hole - i.e. the ring profile completely surrounded by the stopper material to be melted - ensures that a shrinking closure relative to the container material is even closer to the ring when shrinking than originally when it was poured into the closure hole . If the cross-section of the ring increases from the circumferential surface of the closure hole in the direction of the hole axis in the manner according to the invention, a completely sealed closure results, even with plugs shrunk relative to the material of the closure hole wall, which - if possible with the avoidance of excessive pressure - only increases by melting the plug is open. This advantage is further enhanced by the fact that the path which the product in the container would have to cover - past the stopper - in order to get out of the container is increased in a labyrinthine manner by the shape of the ring according to the invention.

Anhand der schematischen Darstellung eines Ausführungsbeispiels werden Einzelheiten der Erfindung erläutert. Es zeigen:

  • Fig. 1 eine perspektivisch dargestellte Viereckflasche mit Deckel; und
  • Fig. 2 einen Schnitt durch einen Behälterdeckel.
Details of the invention are explained on the basis of the schematic representation of an exemplary embodiment. Show it:
  • Figure 1 is a perspective bottle with a lid shown. and
  • Fig. 2 shows a section through a container lid.

In Fig. 1 wird eine insgesamt mit 1 bezeichnete Flasche aus Polyäthylen mit Viereckquerschnitt schematisch dargestellt. Die Flasche 1 besitzt auf der Schulter bzw. Oberseite 2 einen Hals 3 mit Deckel 4. Der Viereckquerschnitt der Flasche 1 bedingt eine relativ hohe Stauchlast beim Stapeln. Für ein sicheres Stapeln kann die Deckeloberseite 5 großflächig sowie eben bzw. parallel zum Flashenboden 6 ausgebildet werden. Die Stauchlast kann bei relativ geringer Wandstärke des Flaschenkörpers durch kuppelartige Ausbildung der Oberseite 2 zusätzlich erhöht werden.In Fig. 1, a generally designated 1 bottle made of polyethylene with a square cross-section is shown schematically. The bottle 1 has a neck 3 with a lid 4 on the shoulder or upper side 2. The square cross section of the bottle 1 requires a relatively high crushing load when stacking. For secure stacking, the top side 5 of the lid can be formed over a large area and even or parallel to the bottom 6 of the bottle. With a relatively small wall thickness of the bottle body, the compression load can be additionally increased by the dome-like design of the upper side 2.

Vorzugsweise wird die viereckige Polyäthylenflasche 1 nach Fig. 1 so ausgelegt, daß bei vorgegebener Stapelhöhe eine noch ausreichende Stauchlast erreicht wird, aber die Wandungen so elastisch bleiben, daß sie einer temperaturbedingten Druckänderung im Flascheninnern nachgeben können. Die Wände der Flasche 1 sollen insbesondere so leicht aufzublähen oder zusammenzuziehen sein, daß Druckänderungen im Flascheninnern nicht zu einer Beeinträchtigung des im Flaschenhals 3 vorgesehenen Stopfens nach Fig. 2 führen können.1 is designed so that a sufficient compressive load is achieved at a given stack height, but the walls remain so elastic that they can yield to a temperature-related change in pressure inside the bottle. The walls of the bottle 1 should in particular be so easy to inflate or contract that pressure changes in the interior of the bottle cannot impair the stopper provided in the bottle neck 3 according to FIG. 2.

Einzelheiten des Deckels 4 und des darin vorgesehenen Schmelzverschlusses werden anhand von Fig. 2 erläutert. Diese zeigt einen Schnitt durch den Deckel 4 eines Reinigungsmittelbehälters, z.B. der Flasche 1 nach Fig. 1. Im Ausführungsbeispiel handelt es sich um einen Schraubdeckel 4 mit Innengewinde 8 und mit einer ein insgesamt mit 9 bezeichnetes Verschlußloch aufweisenden Deckeloberseite 5. Das Verschlußloch 9 wird vorzugsweise symmetrisch zur Lochachse 10 angeordnet und in Richtung der Lochachse 10 so lang gemacht, daß in das Loch 9·eingefülltes Schmelzmaterial, wie Paraffin, bis zu einer vorgegebenen Temperatur einen auch für eine Lagerung ausreichend sicheren Verschlußstopfen 7 bildet. Ein vorzeitiges Lösen des Verschlußstopfens 7 aus dem Verschlußloch 9 wird durch einen auf der Innenfläche bzw. auf der inneren Umfangsfläche 11 des Verschlußlochs 9 symmetrisch zur Lochachse 10 umlaufend angeformten Ring 12 verhindert.Details of the cover 4 and the fuse closure provided therein are explained with reference to FIG. 2. This shows a section through the lid 4 of a Rei Detergent container, for example the bottle 1 according to FIG. 1. In the exemplary embodiment, it is a screw cap 4 with an internal thread 8 and with a cap top 5 having a total of 9 closure hole. The closure hole 9 is preferably arranged symmetrically to the hole axis 10 and in the direction of the Hole axis 10 made so long that melt material, such as paraffin, filled into the hole 9 forms a sealing plug 7, which is also sufficiently secure for storage up to a predetermined temperature. A premature loosening of the sealing plug 7 from the sealing hole 9 is prevented by a ring 12 formed on the inner surface or on the inner peripheral surface 11 of the sealing hole 9 and formed symmetrically around the hole axis 10.

Der Stopfen 7 kann beispielsweise durch Eingießen des Schmelzmaterials in das Verschlußloch 9 hergestellt werden. Hierzu wird das Verschlußloch 9 auf der Deckeloberseite 5 mit einer Siegelfolie 13 verschlossen, und das Schmelzmaterial wird in das Verschlußloch 9 bei auf dem Kopf, also auf der Deckeloberseite 5, stehendem Deckel 4 eingegossen. Dabei kann auf der Deckelinnenseite ein konkaver Meniskus 14 im erstarrten Stopfen 7 entstehen.The plug 7 can be produced, for example, by pouring the melt material into the sealing hole 9. For this purpose, the sealing hole 9 is closed on the top 5 of the lid with a sealing film 13, and the melting material is poured into the sealing hole 9 when the lid 4 is upside down, ie on the top 5 of the lid. A concave meniscus 14 can form in the solidified stopper 7 on the inside of the lid.

Vorzugsweise weist der an die innere Umfangsfläche 11 des Verschlußlochs 9 angeformte Ring 12 eine zu der senkrecht zur Lochachse 10 in der Ringmitte verlaufenden Ebene 15 spiegelsymmetrische Dickenzunahme, z.B. mit einem Schwalbenschwanz-Profil oder T-Profil, auf.Preferably, the ring 12 formed on the inner circumferential surface 11 of the locking hole 9 has a thickness-symmetrical increase in thickness, for example in the plane 15 running perpendicular to the hole axis 10 in the center of the ring, e.g. with a dovetail profile or T-profile.

Wenn das Verschlußloch 9 an seiner inneren Umfangsfläche 11 mit einem angeformten Ring 12 mit Schwalbenschwanz-Profil ausgestattet und das Profil voll von dem eingegossenen Stopfennaterial umschlossen wird, ergibt sich beim Schrumpfen des Stopfens 7 ein zunehmend dichterer Verschluß, da das schrumpfende Material sich noch enger als ursprünglich beim Gießen an die der Umfangsfläche 11 zugewandten äußeren, von der Lochachse 10 weggewandten Flanken 16 des Schwalbenschwanz-Profils anlegt. Außerdem wird bei dieser Ausbildung des Rings 12 der Weg, den das im jeweiligen Behälter enthaltene Produkt am noch festen Stopfen 7 vorbei zurücklegen müßte, um durch das Verschlußloch 9 hindurch zu kommen, labyrinthartig vergrößert.If the closure hole 9 is provided on its inner circumferential surface 11 with a molded ring 12 with a dovetail profile and the profile is fully enclosed by the cast plug material, he there is an increasingly denser closure when the plug 7 shrinks, since the shrinking material lies even closer than originally during casting to the outer surfaces 16 of the dovetail profile facing the peripheral surface 11 and facing away from the hole axis 10. In addition, in this configuration of the ring 12, the path that the product contained in the respective container would have to cover past the still fixed stopper 7 in order to get through the closure hole 9 is increased in a labyrinthine manner.

Zum Stabilisieren des Stopfens 7 innerhalb des Verschlußlochs 9 wird außerdem die Siegelfolie 13 vorgesehen. Diese kann aus mit Polypropylenlack beschichtetem Aluminium von etwa 40 Mikrometer Dicke bestehen sowie eine freistehende Lasche 17 zum Erleichtern des Abziehens besitzen.In order to stabilize the stopper 7 within the sealing hole 9, the sealing film 13 is also provided. This can consist of aluminum coated with polypropylene lacquer of about 40 micrometers thickness and can have a free-standing tab 17 to make it easier to pull off.

Das stabile Aufbringen durch Heißsiegelung der Folie 13 auf die Deckeloberseite 5 wird vereinfacht, wenn um das Verschlußloch 9 herum auf der Deckeloberseite 5 eine ringförmige Erhöhung 18 zum Aufsiegeln der Verschlußfolie 9 vorgesehen wird. Das Maß der Erhöhung 18 relativ zur restlichen, vorzugsweise ebenen, Deckeloberseite 5 kann in der Größenordnung der Dicke der Siegelfolie 13 liegen. Wenn die Siegelfolie 13 auf diese Weise relativ fest auf der Deckeloberseite 5 verankert wird, kann sie die Stabilität des Stopfens 7 gegenüber vom Behälterinnern her wirkenden Über- oder Unterdrücken unterstützen. Eine in diesem Sinne günstige Versteifung der Siegelfolie 13 kann durch Feinprägung des Folienmaterial erreicht werden.The stable application by heat sealing the film 13 to the top side 5 of the lid is simplified if an annular elevation 18 for sealing the closing film 9 is provided around the closing hole 9 on the top side 5 of the lid. The dimension of the elevation 18 relative to the remaining, preferably flat, top 5 of the lid can be of the order of the thickness of the sealing film 13. If the sealing film 13 is anchored relatively firmly in this way on the top side 5 of the lid, it can support the stability of the stopper 7 against overpressure or underpressure acting from the inside of the container. A favorable stiffening of the sealing film 13 in this sense can be achieved by fine stamping of the film material.
