Description

Die Erfindung betrifft einen Reinigungsmittelbehälter oder dergleichen, mit einem Schmeizverschluss, 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 freigebendem 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 (EP-A-32 682).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 outlet of product located in the container, preferably made of paraffin , is formed, with a ring raised in the direction of the axis of the sealing hole to hold the still unmelted plug on the peripheral surface of the sealing hole (EP-A-32 682).

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 Schmelzverschluss 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 has been 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 melts only at the temperature that is most favorable for the use of the product, i.e. the product only at this moment enters the engine room. The plug must also not be able to slide out of its position in the closure hole of the container without melting, so 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, in Folge von Temperaturschwankungen, zu einem unerwünschten Kriechen des Produkts zwischen der Umfangsfläche des Verschlusslochs und dem Stopfen kommen. Dieser Effekttritt besonders bei stark benetzendem, kriechfreudigem Produkt auf. Eine Ursache für den Produktsaustritt besteht darin, dass durch Temperaturschwankungen winzige Spalte zwischen der Wandung bzw. Umfangsfläche des Verschlusslochs und dem darin eingesetzten, inbesondere eingegossenen, Schmelz-Stopfen entstehen, durch die das Produkt, gegebenenfalls über den Wulst hinweg, hindurchwandern kann.When closed product containers of the aforementioned type are stored, undesirable creeping of the product between the peripheral surface of the closure hole and the stopper can occur as a result of temperature fluctuations. This effect occurs particularly in the case of a strongly wetting, creep-friendly product. One reason for the product to emerge is that, due to temperature fluctuations, tiny gaps arise between the wall or peripheral surface of the sealing hole and the, in particular cast-in, melting plug inserted therein, through which the product can migrate, possibly over the bead.

Dieses Problem könnte durch Angleichen derTemperatur-Ausdehnungskoeffizienten 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 materials for the container and the fuse is already determined by a large number of other requirements, e.g. 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 Schmelzschluss gut abgedichteter Produktbehälter erhalten wird, ist bei durch Temperaturerhöhung gasenden Produkten unterhalb der Schmelzemperatur 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 that is well sealed by the fusion is obtained, an overpressure inside 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. The overpressure may also act 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. Dekkelwandung 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 of creating a seal preventing the premature escape of the product located in the container, which seal is also effective with different temperature expansion behavior of the container or cover wall on the one hand and the stopper located in the closure hole of the container on the other. In particular, it is to be prevented that the stopper can be changed in its position relative to the sealing 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 Schmeizverschluss 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 melting seal provided in a sealing hole and with a raised ring molded onto the peripheral surface of the sealing hole in the direction of the hole axis, the solution according to the invention is that the ring extends radially from the peripheral 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 have an increase in thickness that is mirror-symmetrical to the plane perpendicular to the hole axis, approximately through the hole center. 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 a further 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 by an annular increase on the outside of the container, in particular the lid, around the sealing hole for particularly reliable sealing Closure film is provided. In addition, the film covering the sealing 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 increase with occasionally higher outside temperatures without disturbing the relatively soft plug in the shape or position affect. According to this, the wall thickness should preferably be in the range between a minimum value corresponding to the predetermined stack height, in particular of at least about 0.7 mm, on the one hand, and a maximum value permitting elastic stretching and shrinking in the event of a temperature-related pressure change, in particular of at least about 0.05 bar, on the other hand lie.

Im übrigen wird durch die erfindungsgemässe Ausbildung der inneren Umfangsfläche des Verschlusslochs - also des vollständig von dem zu schmelzenden Stopfmaterial 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.Moreover, the inventive design of the inner circumferential surface of the closure hole - that is, the ring profile completely surrounded by the stuffing material to be melted - means that a melt closure that shrinks relative to the container material even more closely adjoins 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 when the plug melts is open. This advantage is further enhanced by the fact that the path that the product in the container would have to cover - past the stopper - in order to get out of the container is enlarged in a labyrinth-like 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 Flaschenboden 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 lid top 5 can be formed over a large area as well as flat or parallel to the bottle base 6. 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.The rectangular polyethylene bottle 1 according to FIG. 1 is preferably designed in such a way 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 pressure change inside the bottle. The walls of the bottle 1 should, in particular, be so easy to inflate or contract that pressure changes in the bottle interior 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 detergent container, e.g. 1 in the exemplary embodiment is a screw cap 4 with an internal thread 8 and with a cap top 5 which has 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 long made that melt material filled into the hole 9, such as paraffin, forms a sealing plug 7, which is also sufficiently secure for storage up to a predetermined temperature. A premature release 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 circumferential surface 11 of the sealing hole 9 and formed circumferentially symmetrical to 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 Dikkenzunahme, 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 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 Stopfenmaterial 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 SchwalbenschwanzProfils 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 sealing hole 9 is provided on its inner circumferential surface 11 with an integrally formed ring 12 with a dovetail profile and the profile is completely enclosed by the cast-in plug material, the plug 7 shrinks more and more, since the shrinking material is even narrower than originally applied during casting to the outer flanks 16 of the dovetail profile facing the peripheral surface 11 and facing away from the hole axis 10. In addition, with this configuration of the ring 12, the path that the product contained in the respective container would have to travel past the still fixed plug 7 in order to get through the sealing 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 plug 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 Dekkeloberseite 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 Folienmaterials 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 extent of the increase 18 relative to the remaining, preferably flat, top 5 of the lid can be of the order of magnitude of the thickness of the sealing film 13. If the sealing film 13 is anchored relatively firmly on the top 5 of the lid in this way, it can support the stability of the stopper 7 against overpressures or underpressures acting from the inside of the container. A favorable stiffening of the sealing film 13 in this sense can be achieved by finely embossing the film material.

Claims (7)

1. Cleansing agent container or the like with a fusion closure which consists of a plug (7), which is disposed in a closure hole (9) of the container (1), in particular in its lid (4), and of a material, preferably of paraffin wax, melting at predetermined temperature and freeing the closure hole (9) for the exit of the product disposed in the container (1), wherein a ring (12), which is raised in the direction of the axis (10) of the closure hole (9), for the tetention of the still un- molten plug (7) is shaped on at the circumferential surface (11) of the closure hole (9), characterised thereby, that the ring (12) displays an increase in thickness in the course of its radial extent from the circumferential surface (11) radially inwards in the direction of the hole axis (10).
2. Container according to claim 1, characterised by an increase in thickness of the ring (12) in mirror symmetry to the plane (15) passing through the ring centre perpendicularly to the hole axis (10).
3. Container according to claim 1 or 2, characterised thereby, that the ring (12) possesses a dovetail profile.
4. Container according to claim 1 or 2, characterised thereby, that the ring (12) possesses a T-profile.
5. Container according to one or more of the claims 1 to 4, characterised thereby, that an annular protrusion (18) for the sealing-on of a closure film (13), in particular with exposed pull tag (17), is provided around the closure hole (9) on the outward side of the container (1), in particular of the lid (4).
6. Container according to claim 5, characterised thereby, that the film (13) covering the closure hole (9) consists of aluminium, in particular of a thickness of about 40 micrometres, which is finely embossed in the sense of an increase in stiffnes and coated by polypropylene varnish.
7. Container according to one or more of the claims 1 to 6, characterised by the construction as polyethylene bottle (1), preferably of quadrangular cross-section, the wall thickness of which lies in the range between on the one hand a minimum value, in particular of at least about 0.7 millimetres, corresponding to a predetermined stacking height and on the other hand a maximum value permitting an elastic expansion and shrinkage in the case of a pressure change, in particular of at least about 0.05 bars, in the interior of the bottle caused by temperature.
