Abstract

There is provided an attachment having a pot-shaped bottom element and a sealing cap adapted to be arranged on the neck of tubes, bottles or the like. The top side of the ceiling of the bottom element, which is supported by the side wall of the pot-shaped bottom element, is fitted with brush-like bristles which are covered by the sealing cap. The central region of the bottom element ceiling is provided with an orifice into which projects a tongue extending from the bottom side of the sealing cap, the free end of the tongue entering the orifice in the ceiling of the bottom part and sealing the same in the manner of a plug. The sealing cap has in the bottom edge region a female thread which cooperates with a male thread on the neck of the tube so that the side wall of the bottom element and the female thread of the sealing cap oppose one another in the same cross-sectional plane thus resulting in a space-saving association of the bottom element having the brush-like bristles, such association being close to the neck.

Description

Die Erfindung betrifft einen auf dem Hals von Tuben, Flaschen oder dergleichen anzuordnenden Aufsatz gemäß Oberbegriff des Anspruchs 1.The invention relates to an attachment to be arranged on the neck of tubes, bottles or the like according to the preamble of claim 1.

Ein Aufsatz dieser Art ist durch das DE-GM 82 31 682 bekannt. Dort erstreckt sich der Zuordnungsbereich des die borstenähnlichen Streichkörper tragenden Unterteils des Aufsatzes in relativ weitem Abstand oberhalb der Verschlußkappe und Hals miteinander verbindenden Gewindezone. Letzteres erfordert einen recht langen Hals und eine entsprechend große Verschlußkappenlänge. Die hieraus folgende Materialverschwendung ist erheblich. Immerhin handelt es sich bei solchen Auftragspackungen um einen Massenartikel.An article of this type is known from DE-GM 82 31 682. There, the area of assignment of the lower part of the attachment which carries the bristle-like coating bodies extends at a relatively large distance above the sealing cap and neck connecting the threaded zone. The latter requires a fairly long neck and a correspondingly large cap length. The resulting waste of material is significant. After all, such order packs are mass-produced items.

Aufgabe der Erfindung ist es, einen gattungsgemäßen Aufsatz an Tuben, Flaschen oder dergleichen zu schaffen, bei dem das den Borstenkörper bildende Unterteil so nah wie möglich an den Bereich des Halsansatzes verlegt werden kann, dies bei kompakter, platzsparender Ausbildung solcher Auftragspackungen.The object of the invention is to provide a generic attachment to tubes, bottles or the like, in which the lower part forming the bristle body can be laid as close as possible to the area of the neck attachment, with a compact, space-saving design of such order packs.

Gelöst ist diese Aufgabe durch die im Anspruch 1 angegebene Erfindung.This object is achieved by the invention specified in claim 1.

Die Unteransprüche sind vorteilhafte Weiterbildungen des Erfindungsgegenstandes.The subclaims are advantageous developments of the subject matter of the invention.

Zufolge solcher Ausgestaltung ist ein äußerst gedrungener Aufsatz an Tuben, Flaschen oder dergleichen Auftragspackungen erzielt: Die für eine sichere Zuordnung des Unterteiles erforderliche axiale Mindestlänge ist sinnvoll genutzt für die Unterbringung des Innengewindes der Verschlußkappe. Dies führt zu einer äußerst platzsparenden Bauform; die dadurch gewonnene axiale Länge läßt sich volumenmäßig nutzen, d. h. bei gleicher Ausgangslänge entsprechender Packungen kann mehr Füllinhalt angeboten werden. Die Verschlußkappe ist überdies handlicher. Sie kann ergonometrisch besser gefaßt werden als ein langes becherartiges Gebilde. Ein fester Sitz der zu verbindenden Teile wird mit einfachen Mitteln dadurch erreicht, daß die Mantelfläche der Topfwandung eine Kehle zum Einschnappen des Halses der Tube oder dergleichen besitzt. Letzterem ist der korrespondierende Schnappwulst angeformt. Selbst hohe mechanische, am Unterteil wirkende Kräfte sind nicht in der Lage, die entsprechende Verankerung zu beeinträchtigen. In dichtungstechnischer Hinsicht sowie in Bezug auf ein vorteilhaftes Einspannen des Unterteils unter Beteiligung der Verschlußkappe ergibt sich dadurch, daß die Innenwand der Verschlußkappe einen auf die Randzone der Unterteil-Decke aufsetzenden Dichtungswulst besitzt, welche Randzone den Stirnrand des Halses übergreift. Darüber hinaus erweist es sich als vorteilhaft, daß von der Mündungsöffnung ein bis etwa auf die Unterkante der Topfwandung reichender Kragen ausgeht. Neben einem strangformenden Effekt hat dieser zugleich eine stabilisierende Funktion, so daß die Decke des Unterteils sogar recht dünnwandig ausgebildet werden kann. Ein solch langer Kragen läßt sich darüber hinaus auch vorteilhaft zur Abdichtung nutzen. Diesbezüglich wird so vorgegangen, daß in den Kragen ein abgesetzter Endabschnitt des Dornes eintritt. In vorteilhafter Weise ist der Dorn hohl gestaltet und als Einziehung der Oberseite der Verschlußkappe ausgebildet. Ein entsprechender Hohldorn ist flexibler und erweist sich auch als anpassungsfähiger in Bezug auf toleranzbedingt unterschiedliche Mündungsöffnungen. Weiter wird vorgeschlagen, daß im Kragen ein Ventilteller angeformt ist. Letzterer bildet eine überwindbare Sperre für das auszubringende Medium. In der abwärts gerichteten Stellung der Mündungsöffnung läuft der Inhalt nicht unkontrolliert aus. Es bedarf vielmehr einer willensbetonten Verdrängung durch Belastung der Wandung der Tube oder dergleichen. So kann die Bürstentätigkeit durchgeführt werden, ohne daß zwangsläufig der Füllinhalt austritt. Dadurch, daß weiter der Dorn mit seinem freien Ende den Ventilteller in Schließstellung beaufschlagt, erhält der Dorn eine zusätzliche Funktion. Endlich bringt die Erfindung noch in Vorschlag, daß die Mantelwand des Kragens eine Eingriffsnut für die Durchbrechungs-Randkante einer Querwand des Halses der Tube oder dergleichen besitzt. Auf diese Weise ergibt sich eine zusätzliche Verankerung für das Unterteil, und zwar in seinem zentralen Bereich. Auch diese Verankerung liegt in der gleichen Querschnittsebene wie der Topfrand und das Innengewinde. Endlich ist es noch von Vorteil, daß der untere Bereich der Topfwandung, also der Topfrand in eine Ringnut des Halses eintritt. Eine solche Ausgestaltung dient zugleich als Sicherung der etwas darüberliegenden Klipsverbindung zwischen der Mantelfläche des Topfwandung und der korrespondierenden Fläche des Halses.As a result of such a configuration, an extremely compact attachment to tubes, bottles or similar order packs is achieved: the minimum axial length required for a safe assignment of the lower part is sensibly used for accommodating the internal thread of the closure cap. This leads to an extremely space-saving design; the resulting axial length can be used in terms of volume, ie with the same starting length of corresponding packs, more filling content can be offered. The cap is also more manageable. Ergonomically, it can be grasped better than a long, cup-like structure. A tight fit of the parts to be connected is achieved by simple means in that the outer surface of the pot wall has a throat for snapping the neck of the tube or the like. The corresponding snap bead is molded onto the latter. Even high mechanical forces acting on the lower part are unable to affect the corresponding anchoring. In terms of sealing technology and in relation to an advantageous clamping of the lower part with the involvement of the closure cap, this results in that the inner wall of the closure cap has a sealing bead which is placed on the edge zone of the bottom part ceiling and which edge zone overlaps the front edge of the neck. In addition, it proves to be advantageous that a collar extending from the mouth opening extends approximately to the lower edge of the pot wall. In addition to a strand-forming effect, this also has a stabilizing function, so that the ceiling of the lower part can even be made with very thin walls. Such a long collar can also be used advantageously for sealing. In this regard, the procedure is such that a stepped end portion of the mandrel enters the collar. Advantageously, the mandrel is hollow and designed as a retraction of the top of the cap. A corresponding hollow mandrel is more flexible and also proves to be more adaptable with regard to different mouth openings due to tolerances. It is also proposed that a valve plate is formed in the collar. The latter forms an insurmountable barrier for the medium to be applied. In the downward position of the mouth opening, the contents do not leak out in an uncontrolled manner. Rather, what is needed is a deliberate displacement by loading the wall of the tube or the like. In this way, brushing can be carried out without the filling contents inevitably escaping. The fact that the mandrel continues to act on the valve plate in its closed position with its free end gives the mandrel an additional function. Finally, the invention proposes that the jacket wall of the collar has an engagement groove for the perforated edge of a transverse wall of the neck of the tube or the like. In this way there is an additional anchoring for the lower part, namely in its central area. This anchorage is also in the same cross-sectional plane as the pot rim and the internal thread. Finally, it is advantageous that the lower area of the pot wall, that is, the rim of the pot, enters an annular groove in the neck. Such a configuration also serves to secure the clip connection lying somewhat above it between the lateral surface of the pot wall and the corresponding surface of the neck.

The subject matter of the invention is explained in more detail below on the basis of an illustrative embodiment. It shows

Die bspw. ein Textil-Reinigungsmittel, Schuhcreme oder dergleichen Aufstreichmittel enthaltende Tube 1 besteht aus Kunststoff und läßt sich zum Ausbringen des Mediums zusammendrücken. Der Bodenbereich ist bspw. thermisch verschlossen. Die Schweißnaht trägt das Bezugszeichen 2. Das andere Ende der Tube 1 geht, wie aus Fig. 2 deutlich erkennbar, über einen etwas eingezogenen, eine gerundete Schulter bildenden Rand 3 in einen kurzen Hals 4 über. Der Schultervorsprung ist nur gering.The tube 1, for example containing a textile cleaning agent, shoe polish or similar spreading agent, is made of plastic and can be compressed to discharge the medium. The floor area is thermally closed, for example. The weld seam bears the reference symbol 2. The other end of the tube 1, as can be clearly seen from FIG. 2, merges into a short neck 4 via a somewhat retracted edge 3 forming a rounded shoulder. The shoulder protrusion is only slight.

Der Hals 4 ist von einem zuordbaren Aufsatz A überfangen. Bestandteile dieses Aufsatzes sind ein topfförmiges, dem Hals 4 im Wege der Klipsverbindung zuordbares Unterteil 5 und eine dieses in Schließstellung der Tube überfangende Verschlußkappe 6. Auch diese Teile bestehen aus auf ihren Einsatzzweck abgestimmtem Kunststoffmaterial. So ist bezüglich des Unterteils solches Material verwendet, welches zur Ausbildung aufrechtstehender, borstenähnlicher Streichkörper 7 optimal geeignet ist, welche dem Unterteil gleich angeformt sind. Die Verschlußkappe 6 bildet einen diese Streichkörper 7 überfangenden Schutzraum 8 aus.The neck 4 is covered by an assignable attachment A. Components of this attachment are a pot-shaped lower part 5, which can be assigned to the neck 4 by means of the clip connection, and a closure cap 6 which grips this in the closed position of the tube. With regard to the lower part, material is used which is optimally suitable for the formation of upright, bristle-like coating bodies 7 which are molded onto the lower part in the same way. The closure cap 6 forms a protective space 8 which overlaps this coating body 7.

Die praktisch von der Decke 5′ des topfförmigen Unterteiles 5 ausgehenden Streichkörper 7 weisen im mittleren Bereich eine Unterbrechung (Borstenaussparung 33) auf. In dieser zentralen Zone erstreckt sich ein von der Verschlußkappen-Unterseite ausgehender Dorn 9. Letzterer ist hohl gestaltet und als von der Oberseite 6′ der Verschlußkappe 6 ausgehende Einziehung 10 realisiert.The practically from the ceiling 5 'of the pot-shaped lower part 5 spreading body 7 have an interruption in the central region (bristle recess 33). In this central zone extends a mandrel extending from the bottom of the cap 9. The latter is hollow and realized as a retraction 10 starting from the top 6 'of the cap 6.

Das freie, zunächst zylindrische, dann aber kuppelartig auslaufende Ende 9′ des Dornes 9 tritt stopfenartig verschließend in eine Mündungsöffnung 11 der Decke 5′ des Unterteils 5 ein.The free, initially cylindrical, but then dome-like tapered end 9 'of the mandrel 9 closes in a stopper-like manner into an opening 11 in the ceiling 5' of the lower part 5.

Gebildet ist die Mündungsöffnung 11 im Bereich eines Kragens 12. Letzterer erstreckt sich gleichgerichtet zur tubenwärts weisenden Einziehung 10 und schließt mit seinem freien Ende im wesentlichen ebenengleich mit dem Stirnrand 13′ der im Grunde zylindrischen Topfwandung 13 des Unterteils 5 ab. Das in die vom Kragen 12 gebildete, zylindrische Mündungsöffnung 11 eintretende Ende 9′ des Dornes 9 ist gegenüber der tubenseitig schwach trichterförmigen Einziehung 10 abgesetzt. Die auf den oberen Rand der Mündungsöffnung 11 dichtend aufsetzende Schulter trägt das Bezugszeichen 14.The mouth opening 11 is formed in the region of a collar 12. The latter extends in the same direction as the tube-facing indentation 10 and closes with its free end essentially at the same level as the end edge 13 'of the basically cylindrical pot wall 13 of the lower part 5. The entering into the cylindrical opening 11 formed by the collar 12, the end 9 'of the mandrel 9 is offset from the tube-side weakly funnel-shaped indentation 10. The shoulder which seals onto the upper edge of the mouth opening 11 bears the reference number 14.

Zur klipstechnischen Befestigung bzw. zum Aufklipsen des Unterteils 5 am Hals 4 der Tube 1 weist die Mantelfläche der Topfwandung 13 auf mittlerer Höhe eine Kehle 15 auf. Letztere erstreckt sich umlaufend. In sie schnappt ein Vorsprung 16 an der korrespondierenden Innenfläche des Halses 4 ein. Der Vorsprung 16 ist als Ringwulst realisiert. Seine obere und untere Flanke sind gebrochen. Dies und eine Fasung an der unteren Außenkante der Topfwandung 13 erleichtern das Zuordnen des Bürstenkörpers.For clip fastening or for clipping the lower part 5 to the neck 4 of the tube 1, the lateral surface of the pot wall 13 has a throat 15 at a medium height. The latter extends all around. A protrusion 16 snaps into the corresponding inner surface of the neck 4. The projection 16 is realized as an annular bead. Its top and bottom flanks are broken. This and a chamfer on the lower outer edge of the pot wall 13 facilitate the assignment of the brush body.

Der untere Bereich des Topfrandes tritt dabei, wie aus Fig. 2 ersichtlich, in eine Ringnut 17 des Halses 4. Nach außen begrenzt ist diese Ringnut 17 durch den im Rand 3 der Tube 1 wurzelnden unteren Abschnitt des Halses 4, unten durch einen Abschnitt 18′ einer die Tube 1 aufsatzseitig begrenzenden Querwand 18 und einwärtsgerichtet durch eine parallel zum Hals 4 verlaufende, von dem Abschnitt 18′ der Querwand 18 ausgehende Ringwand 19. Deren ringnutseitige Oberkante ist gefast, so daß der Topfrand dort gut eingelenkt wird, wo er sich im übrigen unter Schließbelastung der Klipsverbindung an der Ringwand 19 abstützt.The lower region of the pot rim enters, as shown in FIG. 2, into an annular groove 17 of the neck 4. This annular groove 17 is delimited on the outside by the lower section of the neck 4 rooted in the edge 3 of the tube 1 and below by a section 18 'One of the tube 1 delimiting transverse wall 18 and directed inward by a parallel to the neck 4, from the section 18' of the transverse wall 18 outgoing ring wall 19. The ring groove side upper edge is chamfered, so that the pot edge is well deflected where it is in rest supported under closing load of the clip connection on the ring wall 19.

Die Querwand 18 verläuft praktisch nur im Bereich der Ringnut 17 horizontal, d. h. senkrecht zur Längsmittelachse x-x der Tube; innenseitig der Ringwand 19 steigt sie nämlich trichterförmig in Richtung der Verschlußkappe 6 an, und zwar etwa bis auf die mittlere Höhe des Kragens 12. Die Mantelwand des Kragens 12 formt eine Eingriffsnut 20. In letztere schnappt die Randkante 21 dieser entsprechend zentral durchbrochenen Querwand 18 ein, so daß nicht nur im peripheren Bereich des Unterteils 5, sondern ebenso auch im zentralen Bereich desselben eine Verbindungsstelle zwischen Unterteil 5 und Hals 4 der Tube 1 vorliegt. Zum erleichterten Einführen des wie ein hohler Rastzapfen wirkenden zentralen Kragens 12 ist dessen untere Außenkante gefast. Der entsprechend konische Zulauf ergibt sich deutlich aus der zeichnerischen Wiedergabe in den Fig. 2, 4 und 5. Die durch verschlußkappenseitiges Einziehen der Querwand 18 geschaffene Höhlung 22 nimmt den Überstandsabschnitt des Kragens 12 auf; letzterer ragt so nicht in den Innenraum 1′ der Tube 1, so daß das Zusammenquetschen bzw. Zusammenfalten des Tubenkörpers keine Behinderung erfährt, der Inhalt also praktisch restfrei ausgegeben werden kann.The transverse wall 18 runs practically horizontally only in the region of the annular groove 17, ie. H. perpendicular to the longitudinal central axis x-x of the tube; on the inside of the ring wall 19, it rises in a funnel shape in the direction of the closure cap 6, approximately up to the middle height of the collar 12. The jacket wall of the collar 12 forms an engagement groove 20. In the latter, the edge 21 of this correspondingly perforated transverse wall 18 snaps into place , so that there is a connection point between the lower part 5 and the neck 4 of the tube 1 not only in the peripheral area of the lower part 5, but also in the central area of the same. In order to facilitate the insertion of the central collar 12, which acts like a hollow locking pin, its lower outer edge is chamfered. The correspondingly conical inlet clearly results from the graphic representation in FIGS. 2, 4 and 5. The concavity 22 created by closing the transverse wall 18 on the closure cap side accommodates the protruding section of the collar 12; the latter does not protrude into the interior 1 'of the tube 1, so that the squeezing or folding of the tube body does not experience any hindrance, so the content can be dispensed practically without residue.

Die behälterinnenseitige Flanke der Eingriffsnut 20 ist abgeschrägt, die behälteraußenseitige dagegen steil gestellt; sie verläuft senkrecht zur Längsmittelachse x-x und mit geringem Abstand oberhalb der wieder in die Horizontale gefalteten Ringzone der Querwand 18. Die Durchbrechung für den Kragen 12 trägt das Bezugszeichen 23.The flank of the engaging groove 20 on the inside of the container is chamfered, whereas the flank on the outside of the container is steep; it runs perpendicular to the longitudinal central axis x-x and at a short distance above the ring zone of the transverse wall 18, which is folded back into the horizontal. The opening for the collar 12 has the reference symbol 23.

Die Zuordnung der Verschlußkappe 6 geschieht über Gewindeeingriff. Der untere, innenseitige Randbereich der Verschlußkappenwand 24 trägt Innengewinde 25. Das entsprechende Gegengewinde 26 befindet sich auf der Mantelwand des Halses 4. Diese Zuordnung ist dergestalt, daß die Topfwandung 13 und das Innengewinde 25 sich auf gleicher Querschnittsebene gegenüberliegen. Zentrale Verrastung und periphere Verrastung sind so auf einem relativ kurzen axialen Abschnitt y untergebracht, der etwas kürzer ist als die Länge der Streichkörper 7 bzw. ca. einem Fünftel des Durchmessers D des Aufsatzes A entspricht.The assignment of the closure cap 6 takes place via thread engagement. The lower, inner edge region of the closure cap wall 24 has an internal thread 25. The corresponding counter thread 26 is located on the jacket wall of the neck 4. This assignment is such that the cup wall 13 and the internal thread 25 lie opposite one another on the same cross-sectional plane. Central locking and peripheral locking are thus accommodated on a relatively short axial section y, which is somewhat shorter than the length of the Brush body 7 or approximately one fifth of the diameter D of the attachment A corresponds.

Die Decke 5′ des Unterteiles 5 überragt die Mantelfläche der Topfwandung 13 derart, daß ein ringförmiger Decken-Auflagerand 27 den Stirnrand 28 des Halses 4 übergreift. Diese topfabstützende Übergrifflage ist gesichert durch einen an der Innenwand der Verschlußkappe 6 liegenden, oben auf die Randzone 27 aufsetzenden Dichtungswulst 29. Letzterer schließt innenseitig ebenenmäßig mit der Innenfläche des Halses ab. Die Unterseite des Dichtungswulstes 29 ist abgeschrägt. Eine entsprechende Abschrägung besitzt auch die Randzone. Unter Gewindeanzug ergibt sich ein klemmendes Zwischenfassen des Auflagerandes 27 zwischen Dichtungswulst 29 und Hals 4. Dem Austritt von noch im Borstenbereich liegendem Medium über das Gewinde ist so wirksam entgegengetreten.The ceiling 5 'of the lower part 5 projects beyond the outer surface of the pot wall 13 in such a way that an annular ceiling support edge 27 engages over the end edge 28 of the neck 4. This pot-supporting overlap position is secured by a sealing bead 29 lying on the inner wall of the closure cap 6 and resting on the edge zone 27 at the top. The latter closes flat on the inside with the inner surface of the neck. The underside of the sealing bead 29 is chamfered. The edge zone also has a corresponding bevel. When tightening the thread, there is a jamming gripping of the support edge 27 between the sealing bead 29 and the neck 4. This effectively counteracts the leakage of medium still lying in the bristle region via the thread.

Um bei Benutzung eine kontrollierte Ausgabe des Füllinhaltes aus der Tube zu erreichen, weist der Kragen 12 innen einen Ventilteller 30 auf. Letzterer ist als Ventilklappe im oberen, etwas querschnittsgrößeren Abschnitt des Kragens angeformt, geht also von einer hinterschnittenen Schulterkante 12′ dieses Kragens aus. Als Gelenkstelle dient eine tubenseitig liegende Materialanformung. Es handelt sich um einen schmalen Zwickel 31. Dieser geht von der Unterseite des Ventiltellers 30 aus und wurzelt in der querschnittsreduzierten Zone der Innenwandung des Kragens 12. Durch eine kegelstumpfförmige Ausbildung des Ventiltellers ergibt sich, wie aus Fig. 5 ersichtlich, ein noch größerer Aufklappwinkel, wie er durch die Stufung im Bereich der Schulterkante ohnehin schon begünstigt ist. Sobald die Tube gequetscht wird, drängt der dosierte Füllinhalt durch den Kragen als Führungskanal über die Mündungsöffnung 11 in den Bereich der zentralen Borstenaussparung 33, wo er sich durch Bürstenbewegung verteilt und an die Streichfläche abgegeben wird.In order to achieve a controlled dispensing of the filling contents from the tube during use, the collar 12 has a valve disk 30 on the inside. The latter is formed as a valve flap in the upper, somewhat larger cross-section of the collar, so it starts from an undercut shoulder edge 12 'of this collar. A molded part on the tube side serves as the joint. It is a narrow gusset 31. This starts from the underside of the valve plate 30 and is rooted in the reduced-cross-section zone of the inner wall of the collar 12. As can be seen in FIG. 5, an even larger opening angle results from a conical shape of the valve plate , as it is already favored by the gradation in the area of the shoulder edge. As soon as the tube is squeezed, the metered filling content pushes through the collar as a guide channel via the mouth opening 11 into the area of the central bristle recess 33, where it is distributed by brush movement and released to the coating surface.

In Schließstellung der Verschlußkappe 6 tritt das freie Ende 9′ des Dornes 9 gegen den Rücken des Ventiltellers 30, der so die lippenartige Ringzone im Bereich der Kante 12′ des Kragens hält.In the closed position of the cap 6, the free end 9 'of the mandrel 9 occurs against the back of the valve plate 30, which thus holds the lip-like ring zone in the region of the edge 12' of the collar.
