Definitions
- the invention is directed to a spray can, which is ergonomically designed to ensure a secure hold of the can during spraying, according to the type specified in the preamble of claim 1 and to an apparatus for producing the spray can according to the type mentioned in the preamble of claim 11 and on a method for producing the spray can with said device according to the type mentioned in the preamble of claim 13.
- Spray cans of this type are widely used for a variety of ingredients, such.
- deodorants hair spray, shaving cream, paints or oils, etc.
- the use of these spray cans is usually complicated by the fact that the fingers that comprise the cylindrical can body, not provide sufficient support of the can when pressing the spray button.
- this problem be easily remedied by the known solutions used in PET beverage bottles.
- additional recessed grips or depressions are mounted on the shell body of the bottle for a better grip.
- the other requirements placed on a PET bottle are quite different from those relating to a spray can that is under high pressure and containing aggressive agents. These differences are clearly identifiable by the material chosen and the manufacturing process, so that new solutions have to be found for the spray can.
- spray cans today are a commodity that can only be produced economically in large quantities. Therefore, there are specially designed production lines where an optimized manufacturing process takes place. This manufacturing process is optimized in terms of manufacturing technology so that hardly any Changes in the production of spray cans are possible without incurring additional costs. Now, if the shape of the known spray cans are modified, this usually means drastic effects on the entire manufacturing process, since either an additional manufacturing process must run on existing machines or additional or new machines are needed.
- a spray can of the type mentioned which has a circumferential recessed grip in the can body, which is removed in about 3-4 cm from the can opening. Namely, it is prevented by this recessed grip that the spray can slides on holding the spray button by the holding fingers, but the entire attitude of the spray can in the hand is quite cumbersome and unnatural. The attitude of the can also complicates with increasing diameter of the can body. Also, the strong sales, resulting from the lower recessed grip and the higher wall of the can, a major disadvantage for the safety of the spray can, since the material of the spray can wall is greatly weakened in this area.
- the known spray cans from the publication DE 299 10 184 U1 , are manufactured by the manufacturing process described below and optimized. First, so-called pellets or blanks are punched out of a metal sheet for the further process. These pellets or blanks are formed into a cylindrical hollow body by a deep drawing process. As a rule, the method of backward hollow pressing is used. After the production of the cylindrical hollow body, this is painted from the inside, so that the spray can chemically withstand the aggressive ingredients and propellants. Also, the cylindrical hollow body is printed or painted on the outside. For printing from the outside, it is important to have a rotationally symmetric object. Therefore, deformations can only be carried out after the printing of the cylindrical hollow body.
- the applied lacquer layers also serve as lubricants for the subsequent deformation steps.
- the upper edge of the cylindrical Hollow body cleanly separated, so as to ensure an exact shape for the can opening with the collar.
- the upper can area is formed with the shoulder and with the can opening and the collar of the cylindrical hollow body.
- FR 2 606 686 A1 including a manufacturing process for spray cans.
- This process also produces spray can bodies which have a non-circular cross-section in the central region.
- sharp-edged and angular profiles are incorporated into the can body, which lead to a material weakening of the wall thickness.
- spray can bodies produced in this way, since they can not be loaded with a corresponding filling pressure without safety risk.
- the attachment of printing instructions in the formed areas is hardly possible. Even if a printing of the can would be possible, the pressure indication can not be read by the user at the highly deformed, angular edge points.
- JP 61-193730 A discloses a manufacturing process for making partially deformed spray cans.
- in part strongly angular or edged deformations are introduced into the spray can body, which also constitute a safety risk. So z.
- the lower can section to transition to the upper can section.
- the invention is therefore an object of the one hand to develop a well-handled spray can mentioned in the preamble of claim 1 species that is ergonomically shaped and still represents no security disadvantage. This is inventively achieved by the measures indicated in the characterizing part of claim 1, the following special significance.
- the spray can in contrast to the known spray cans of the prior art - in the upper doses section on an additional shaping area, which can extend over the entire shoulder region of the spray can.
- the cross section of the spray can is designed differently to the almost circular cross section of the lower can section. That is, the different cross-sections over the longitudinal extent of the spray can usually have no circular cross section, as in the lower portion of the can on.
- This shaping area runs seamlessly, as long as it extends over the shoulder area, into the standardized can opening. Consequently, in the case of the spray cans according to the invention which have a standardized can opening, standardized spray systems can also be used, even if they have no cylindrical body in the shaping area.
- the spray can has a substantially constant wall thickness over the circumference of the cross-section and over its height (longitudinal extension), i. the wall thickness is constant in radial and axial extension. This ensures above all a high level of safety for filled spray cans that are under high pressure.
- the object of the invention on the other hand, to show a device of the type mentioned, so that the production of the spray can be guaranteed without significant changes in a conventional but modified manufacturing process.
- This is inventively achieved by the measures listed in the characterizing part of claim 11, which have the following special significance.
- the matrices of the device that are used for molding the upper portion of the can, according to the invention are designed such that by their chosen contours in addition, the molding area of the spray can also be formed.
- the molding area of the spray can are formed by the die, but also the additional shaping area.
- the matrices in the different cross sections in the shaping area have circumferences of the contours; which are not circular in shape. The so geometrically changed contours of the matrices cause in the molding process of the upper portion of the can also the deformation of the molding area.
- the invention is also based on the object to develop a modified method of the type already mentioned in order to produce the spray cans according to the invention economically in large quantities. This is done essentially by the modified method step in the characterizing part of claim 13.
- the upper can portion with the shoulder region and with the can opening with collar and the additional shaping region by the device according to claim 11 or 12 is formed.
- the manufacturing process for creating the upper can section with the shaping area represents the last manufacturing process in the production process of unfilled spray cans.
- the spray can 10 is made of metal and has a lower and an upper can section 11, 13.
- the lower can section 11 includes a bottom 12 and an almost cylindrically shaped can wall, so that the cross sections of the spray can 10 in the region of the lower can section 11 are designed circular. All cross sections in the region of the lower can portion 11 are circular with the same surface area.
- the upper can portion 13 has a shoulder portion 14 and a can opening 15 with a collar 16 for an insertable spray system.
- Previously known spray cans are also cylindrical in the upper can section 13, so that their cross sections in this area are circular. It is also regarded as circular when the circumference of the circular cross sections has small points or spikes, as in the case of a cross section in the region of the sinusoidal recessed grip from the known publication DE 299 10 184 U1 available.
- the shoulder region 14 represents a transition region in which the larger cross-sectional area of the cylindrical can body tapers continuously to the smaller cross-sectional area of the can opening.

As a result, a sliding away of the spray can 10 is significantly reduced in their use, especially in the operation of the spray system with slippery fingers.
- the lower socket portion 11 has a constant circular cross-section. In this area of the lower can section 11, the spray can 10 - in a production process to be described in more detail - comprises a clamping device 23.
- the spray can 10 has a substantially constant wall thickness over the circumference of the cross section and over the height (longitudinal extent) of the spray can wall. That is, the wall thickness of the spray can 10 is substantially constant in radial and axial extent.
- a high level of safety for the spray can 10 is achieved, in particular with a high filling pressure. This is of great importance, since the filling pressure due to external circumstances, such as
- spray can 10 must withstand special requirements, e.g. the direct sunlight is delivered in the car.
- the surface of the different cross-sections in the shaping area 17 is designed to be oval or elliptical.
- This shape of the spray can 10 ensures ergonomic handling, at the same time maximum safety is achieved. It is advisable to dispense with particularly narrow radii in the circumference of the cross section in the forming area 17.
- the area of the different cross-section in the shaping area 17 can also have any other shape and thus approximate a triangle or rectangle, the corners also being realized here by radii which are as large as possible.

Description
Die Erfindung richtet sich auf eine Spraydose, die ergonomisch ausgestaltet ist um einen sicheren Halt der Dose beim Sprühen sicherzustellen, gemäß der im Oberbegriff des Anspruchs 1 angegebenen Art sowie auf eine Vorrichtung zur Herstellung der Spraydose nach der im Oberbegriff des Anspruchs 11 genannten Art und auf ein Verfahren zur Herstellung der Spraydose mit der genannten Vorrichtung nach dem im Oberbegriff des Anspruchs 13 genannten Art.The invention is directed to a spray can, which is ergonomically designed to ensure a secure hold of the can during spraying, according to the type specified in the preamble of claim 1 and to an apparatus for producing the spray can according to the type mentioned in the preamble of
Spraydosen dieser Art werden vielfältig für die unterschiedlichsten Inhaltstoffe eingesetzt, wie z. B. Deodorants, Haarspray, Rasierschaum, Lacke bzw. Farben, Öle etc. Die Verwendung von diesen Spraydosen wird in der Regel dadurch erschwert, dass die Finger, die den zylindrischen Dosenkörper umfassen, keinen ausreichenden Halt der Dose beim Betätigen des Sprühknopfes bieten. Dieses Problem kann auch nicht ohne Weiteres durch die bekannten Lösungen, die bei PET-Getränkeflaschen Anwendung finden, behoben werden. Bei diesen PET-Flaschen werden zusätzliche Griffmulden oder Vertiefungen auf den Mantelkörper der Flasche für einen besseren Halt angebracht. Jedoch sind die weiteren Anforderungen, die an eine PET-Flasche gestellt werden, gänzlich unterschiedlich von denen die an eine Spraydose, die unter hohem Druck steht und aggressive Mittel enthält. Diese Unterschiede sind eindeutig am gewählten Material und im Herstellungsverfahren auszumachen, so dass für die Spraydose neue Lösungsmöglichkeiten gefunden werden müssen.Spray cans of this type are widely used for a variety of ingredients, such. As the deodorants, hair spray, shaving cream, paints or oils, etc. The use of these spray cans is usually complicated by the fact that the fingers that comprise the cylindrical can body, not provide sufficient support of the can when pressing the spray button. Nor can this problem be easily remedied by the known solutions used in PET beverage bottles. In these PET bottles additional recessed grips or depressions are mounted on the shell body of the bottle for a better grip. However, the other requirements placed on a PET bottle are quite different from those relating to a spray can that is under high pressure and containing aggressive agents. These differences are clearly identifiable by the material chosen and the manufacturing process, so that new solutions have to be found for the spray can.
Des weiteren sind Spraydosen heute eine Massenware, die nur wirtschaftlich in größten Mengen herzustellen sind. Von daher gibt es speziell entwickelte Fertigungsstraßen, auf denen ein optimierter Herstellungsprozess stattfindet. Dieser Herstellungsprozess ist fertigungstechnisch derart optimiert, dass kaum Veränderungen bei der Herstellung von Spraydosen möglich sind, ohne zusätzliche Kosten zu verursachen. Soll nun die Form von den bekannten Spraydosen abgewandelt werden, so bedeutet dieses in der Regel einschneidende Auswirkungen auf den gesamten Herstellungsprozess, da entweder ein zusätzlicher Fertigungsvorgang auf den vorhandenen Maschinen ablaufen muss oder zusätzliche oder neue Maschinen benötigt werden.Furthermore, spray cans today are a commodity that can only be produced economically in large quantities. Therefore, there are specially designed production lines where an optimized manufacturing process takes place. This manufacturing process is optimized in terms of manufacturing technology so that hardly any Changes in the production of spray cans are possible without incurring additional costs.

Der Erfindung liegt somit einerseits die Aufgabe zugrunde, eine gut zu handhabende Spraydose der im Oberbegriff des Anspruchs 1 genannten Art zu entwickeln, die ergonomisch geformt ist und trotzdem kein Sicherheitsnachteil darstellt. Dieses wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruchs 1 angeführten Maßnahmen erreicht, den folgende besondere Bedeutung zukommt.The invention is therefore an object of the one hand to develop a well-handled spray can mentioned in the preamble of claim 1 species that is ergonomically shaped and still represents no security disadvantage. This is inventively achieved by the measures indicated in the characterizing part of claim 1, the following special significance.
Erfindungsgemäß weist die Spraydose - im Gegensatz zu den bekannten Spraydosen aus dem Stand der Technik - im oberen Dosenabschnitt eine zusätzlichen Formgebungsbereich auf, der sich über den gesamten Schulterbereich der Spraydose erstrecken kann. In diesem Formgebungsbereich ist der Querschnitt der Spraydose andersartig zum fast kreisförmigen Querschnitt des unteren Dosenabschnitts ausgestaltet. Das heißt die unterschiedlichen Querschnitte über die Längserstreckung der Spraydose weisen in der Regel keinen kreisförmigen Querschnitt, wie im unteren Dosenabschnitt, auf. Dieser Formgebungsbereich läuft nahtlos, sofern er sich über den Schulterbereich erstreckt, in die genormte Dosenöffnung über. Folglich können bei den erfindungsgemäßen Spraydosen, die über eine genormte Dosenöffnung verfügen, auch genormte Sprühsysteme eingesetzt werde, auch wenn sie im Formgebungsbereich keinen zylindrischen Körper aufweisen.According to the invention, the spray can - in contrast to the known spray cans of the prior art - in the upper doses section on an additional shaping area, which can extend over the entire shoulder region of the spray can. In this shaping region, the cross section of the spray can is designed differently to the almost circular cross section of the lower can section. That is, the different cross-sections over the longitudinal extent of the spray can usually have no circular cross section, as in the lower portion of the can on. This shaping area runs seamlessly, as long as it extends over the shoulder area, into the standardized can opening. Consequently, in the case of the spray cans according to the invention which have a standardized can opening, standardized spray systems can also be used, even if they have no cylindrical body in the shaping area.
Vorteilhafterweise weist die Spraydose eine im wesentlichen gleichbleibende Wandstärke über den Umfang des Querschnitts sowie über ihre Höhe (Längserstreckung) auf, d.h. die Wandstärke ist in radialer und axialer Ausstreckung gleichbleibend. Hierdurch wird vor allen Dingen eine hohe Sicherheit für gefüllte Spraydosen gewährleistet, die unter einem hohen Druck stehen.Advantageously, the spray can has a substantially constant wall thickness over the circumference of the cross-section and over its height (longitudinal extension), i. the wall thickness is constant in radial and axial extension. This ensures above all a high level of safety for filled spray cans that are under high pressure.
Aufgabe der Erfindung ist es andererseits, eine Vorrichtung der eingangs genannten Art aufzuzeigen, damit die Herstellung der Spraydose ohne wesentlichen Veränderungen in einem herkömmlichen aber modifizierten Fertigungsvorgang gewährleistet werden kann. Dieses wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruchs 11 angeführten Maßnahmen erreicht, denen die nachfolgende besondere Bedeutung zukommt.The object of the invention, on the other hand, to show a device of the type mentioned, so that the production of the spray can be guaranteed without significant changes in a conventional but modified manufacturing process. This is inventively achieved by the measures listed in the characterizing part of
Die Matrizen der Vorrichtung die zum Formen des oberen Dosenabschnitts verwendet werden, sind erfindungsgemäß derart ausgestaltet, dass durch ihre gewählten Konturen zusätzlich auch der Formgebungsbereich der Spraydose anformbar ist. Somit wird durch die Matrize nicht nur der Schulterbereich und die Dosenöffnung mit Kragen für das einsetzbare Sprühsystem angeformt, sondern ebenfalls auch der zusätzliche Formgebungsbereich. Hierzu weisen die Matrizen in den verschiedenen Querschnitten im Formgebungsbereich Umfänge der Konturen auf; die nicht kreisförmig ausgestaltet sind. Die so geometrisch veränderten Konturen der Matrizen bewirken im Formprozess des oberen Dosenabschnitts auch die Umformung des Formgebungsbereichs.The matrices of the device that are used for molding the upper portion of the can, according to the invention are designed such that by their chosen contours in addition, the molding area of the spray can also be formed. Thus, not only the shoulder area and the can opening with collar for the applicable spray system are formed by the die, but also the additional shaping area. For this purpose, the matrices in the different cross sections in the shaping area have circumferences of the contours; which are not circular in shape. The so geometrically changed contours of the matrices cause in the molding process of the upper portion of the can also the deformation of the molding area.
Der Erfindung liegt ebenfalls die Aufgabe zugrunde, ein abgeändertes Verfahren der bereits genannten Art zu entwickeln, um die erfindungsgemäßen Spraydosen wirtschaftlich in großen Stückzahlen herzustellen. Dies geschieht im Wesentlichen durch den modifizierten Verfahrensschritt im kennzeichnenden Teil des Anspruchs 13.The invention is also based on the object to develop a modified method of the type already mentioned in order to produce the spray cans according to the invention economically in large quantities. This is done essentially by the modified method step in the characterizing part of
Bei diesem modifizierten Verfahrensschritt wird der obere Dosenabschnitt mit dem Schulterbereich und mit der Dosenöffnung mit Kragen und dem zusätzlichen Formgebungsbereich durch die Vorrichtung nach Anspruch 11 oder 12 angeformt. Somit wird bei dem Verfahren kein zusätzlicher Fertigungsvorgang im Vergleich zu herkömmlichen Fertigungsverfahren, angewendet, sondern vielmehr durch den geänderten bzw. modifizierten Fertigungsvorgang der erfindungsgemäßen Spraydosen 10 hergestellt. Somit wird weitestgehend auf das bekannte Fertigungsverfahren der herkömmlichen Spraydosen (aus dem Stand der Technik) zurückgegriffen, um den optimierten Ablauf so wenig wie möglich zu beeinflussen. Hierdurch können die erfindungsgemäßen Spraydosen ebenfalls kostengünstig hergestellt werden.In this modified process step, the upper can portion with the shoulder region and with the can opening with collar and the additional shaping region by the device according to
Vorteilhafterweise stellt der Fertigungsvorgang zur Erstellung des oberen Dosenabschnitts mit dem Formgebungsbereich den letzten Fertigungsvorgang im Herstellungsprozess von ungefüllten Spraydosen dar.Advantageously, the manufacturing process for creating the upper can section with the shaping area represents the last manufacturing process in the production process of unfilled spray cans.

Die Spraydose 10 besteht aus Metall und weist einen unteren und einen oberen Dosenabschnitt 11, 13 auf. Der untere Dosenabschnitt 11 enthält einen Boden 12 und eine fast zylindrisch ausgestaltete Dosenwand, so dass die Querschnitte der Spraydose 10 im Bereich des unteren Dosenabschnitts 11 kreisförmig ausgestaltet sind. Alle Querschnitte im Bereich des unteren Dosenabschnitts 11 sind kreisförmig mit dem gleichen Flächeninhalt. Der obere Dosenabschnitt 13 weist einen Schulterbereich 14 und eine Dosenöffnung 15 mit einem Kragen 16 für ein einsetzbares Sprühsystem auf. Bisher bekannte Spraydosen sind im oberen Dosenabschnitt 13 ebenfalls zylindrisch ausgestaltet, so dass auch ihre Querschnitte in diesem Bereich kreisförmig sind. Dabei wird auch als kreisförmig angesehen, wenn der Umfang der Kreisquerschnitte kleine Zacken oder Ausbrüche aufweist, wie sie z.B. bei einem Querschnitt im Bereich der sinusförmigen Griffmulde aus der bekannten Druckschrift
Der Schulterbereich 14 stellt einen Übergangsbereich dar, in dem sich die größere Querschnittsfläche des zylindrischen Dosenkörpers kontinuierlich auf die kleinere Querschnittsfläche der Dosenöffnung verjüngt. Bei den bekannten Spraydosen aus dem Stand der Technik sind verschiedene Schulterbereiche 14 bekannt, die eine Rundschulter, Schrägschulter oder Rillenschulter aufweisen. Jedoch ist ein Querschnitt bei den bekannten Schulterbereichen 14 auch immer kreisförmig.The
Bei der erfindungsgemäßen Spraydose 10 ist zusätzlich im oberen Dosenabschnitt 13 ein Formgebungsbereich 17 enthalten, der sich auch über den Schulterbereich 14 erstrecken kann. Querschnitte im Formgebungsbereich 17 der Spraydose 10 sind andersartig zu den fast kreisförmigen Querschnitten des unteren Dosenabschnitts 11 ausgestaltet.In the spray can 10 according to the invention, a shaping
In den
Vorteilhafterweise weist die Spraydose 10 eine im Wesentlichen gleichbleibende Wandstärke über den Umfang des Querschnitts sowie über die Höhe (Längserstreckung) der Spraydosenwand auf. Das heißt, die Wandstärke der Spraydose 10 ist in radialer und axialer Ausdehnung im Wesentlichen gleichbleibend. Hierdurch wird eine hohe Sicherheit für die Spraydose 10, insbesondere bei einem hohen Fülldruck erreicht. Dieses ist von großer Bedeutung, da sich der Fülldruck durch äußere Umstände, wie z.B.Advantageously, the spray can 10 has a substantially constant wall thickness over the circumference of the cross section and over the height (longitudinal extent) of the spray can wall. That is, the wall thickness of the spray can 10 is substantially constant in radial and axial extent. As a result, a high level of safety for the spray can 10 is achieved, in particular with a high filling pressure. This is of great importance, since the filling pressure due to external circumstances, such as
Temperaturschwankungen, stark beeinflussen lässt. So muss die Spraydose 10 auch besonderen Anforderungen standhalten, wenn sie z.B. der direkten Sonnenbestrahlung im Auto ausgeliefert ist.Temperature fluctuations, strongly influenced. Thus, spray can 10 must withstand special requirements, e.g. the direct sunlight is delivered in the car.
Um eine vergleichbare Sicherheit zu herkömmlichen, zylindrisch ausgestalteten Spraydosen zu erzielen, wird vorgeschlagen, dass der Umfang des kreisförmigen Querschnitts aus dem unteren Dosenabschnitt 11 größenmäßig gleich zum Umfang des andersartigen Querschnitts im Formgebungsbereich 17 ausgebildet ist. Durch diese beschriebene Maßnahme besteht ein direkter Einfluss auf die gewünschte gleichbleibende Wandstärke der Spraydose 10. Somit werden starke Verformungen, wie sie aus der Druckschrift
Vorteilhafterweise ist die Fläche der andersartigen Querschnitte im Formgebungsbereich 17 oval oder ellipsenartig ausgestaltet. Durch diese Formgebung der Spraydose 10 wird eine ergonomische Handhabung sichergestellt, wobei gleichzeitig die maximale Sicherheit erzielt wird. Dabei ist es ratsam, auf besonders enge Radien im Umfang des Querschnitts im Formgebungsbereich 17 zu verzichten.Advantageously, the surface of the different cross-sections in the shaping
Ebenfalls kann die Fläche des andersartigen Querschnitts im Formgebungsbereich 17 auch jegliche andere Form innehaben und sich somit einem Dreieck oder Rechteck annähern, wobei auch hier die Ecken durch möglichst große Radien realisiert werden. Durch die frei wählbare Formgestaltung der Spraydose 10 kann auch jede andere ergonomische Handhabung der Dose erzielt werden mit einem gleichzeitigen, wohlgefälligen Aussehen.Likewise, the area of the different cross-section in the shaping
Da, wie bereits erwähnt, Spraydosen heute eine Massenware sind, ist es zweckmäßig, dass die Spraydose 10 eine genormte Dosenöffnung 15 aufweist, in die genormte Sprühsysteme einsetzbar sind. Zu diesem Zweck ist die Dosenöffnung 15 in der Regel kreisförmig ausgestaltet. Hiervon ist ebenfalls der Kragen 16 betroffen, da er auch für die genormten Sprühsysteme von Bedeutung ist.Since, as already mentioned, spray cans today are a commodity, it is expedient that the spray can 10 has a standardized can opening 15 into which standardized spray systems can be used. For this purpose, the
Vorteilhafterweise ist die Spraydose 10 mit einem eingesetzten Sprühsystem für einen Fülldruck zwischen 5 und 35 bar geeignet, insbesondere jedoch für einen Fülldruck zwischen 10 und 20 bar oder für einen Fülldruck zwischen 12 und 18 bar. Wie bereits erwähnt, kann jedoch der Fülldruck deutlich über den genannten Werten liegen, wenn die Sprühdose 10 einer starken Erwärmung ausgesetzt ist.Advantageously, the spray can 10 with a spray system used for a filling pressure between 5 and 35 bar suitable, but in particular for a filling pressure between 10 and 20 bar or for a filling pressure between 12 and 18 bar. As already mentioned, however, the filling pressure can be clearly above the stated values when the aerosol can 10 is exposed to strong heating.
Um die Spraydose 10 kostengünstig und nach einem bekannten, modifizierten Herstellungsverfahren fertigen zu können, ist es ratsam, dass das Metall der Spraydose 10 aus Weißblech oder Aluminium besteht. Selbstverständlich sind hier auch jegliche Legierungen im Bereich von Weißblech oder Aluminium umfasst.In order to be able to manufacture the spray can 10 inexpensively and according to a known, modified manufacturing process, it is advisable that the metal of the spray can 10 be made of tinplate or aluminum. Of course, here are also any alloys in the field of tinplate or aluminum covers.
Zur Herstellung einer erfindungsgemäßen Spraydose 10 (nach einem der Ansprüche 1 bis 10) enthält die Vorrichtung 20 eine oder mehrere Matrizen 24 zur Fertigung des oberen Dosenabschnitts 13 mit dem Schulterbereich 14 und mit der Dosenöffnung 15 mit dem Kragen 16 aus einem zylindrischen Hohlkörper 25 mit Boden 12, wobei durch die Konturen 30 der Matrize 24 die Form des oberen Dosenabschnitts 13 bestimmt ist. Diese Vorrichtung 20 dient zum Pressen der Spraydose 10 aus einem zylindrischen Hohlkörper 25a mit Boden 12. Die Konturen 30 der Matrize 24 sind derart ausgestaltet, dass zusätzlich auch der andersartig Formgebungsbereich 17 der Spraydose 10 anformbar ist, indem bei verschiedenen Querschnitten im Formgebungsbereich 17 einer Matrize 24 die Umfänge 31 der Konturen 30 nicht kreisförmig ausgestaltet sind. Somit wird durch die Vorrichtung 20 auch direkt der andersartige Formgebungsbereich 17 im oberen Dosenabschnitt 13 hergestellt.For producing a
Dieser Fertigungsvorgang besteht jedoch aus einzelnen Fertigungsschritten, wiesie in den
Vorteilhafterweise weisen die Konturen 30 bei verschiedenen Querschnitten im Formgebungsbereich 17 einer Matrize 24 gleich lange Umfänge 31b auf. Hierdurch wird die spezielle Formgebung im Formgebungsbereich 17 der Spraydose 10 erzielt.Advantageously, the contours 30 at different cross sections in the shaping
In der
Es sei an dieser Stelle erwähnt, dass die dargestellten Matrizen 24a, 24b nur beispielhafte Ausgestaltungen sind und so nicht unbedingt in der dargestellten Form im Fertigungsprozess für Spraydosen 10 zum Einsatz kommen. Jedoch sollen sie das Prinzip der einzelnen Umformschritte im Fertigungsvorgang e) darstellen.It should be mentioned at this point that the
Des Weiteren richtet sich die Erfindung auch auf ein Verfahren zur Herstellung der Spraydose 10, bei dem zumindest folgende Fertigungsvorgänge, die selbst aus mehreren Fertigungsschritten bestehen, vorhanden sind:
- a) Fertigung eines fast zylindrischen Hohlkörpers
25a mit Boden 12 aus einem Pellet oder Rohling, - b) Innenlackierung des zylindrischen Hohlkörpers 25a,
- c) Bedruckung oder Lackierung des zylindrischen Hohlkörpers 25a auf der Außenseite
- d) Abschneiden des oberen Randes des zylindrischen Hohlkörpers 25a zum exakten Anformen des Kragens 16
der Dosenöffnung 15 und - e) Fertigung des oberen Dosenabschnitts 13
mit dem Schulterbereich 14 undmit der Dosenöffnung 15mit dem Kragen 16.
- a) production of an almost cylindrical hollow body 25a with
bottom 12 of a pellet or blank, - b) interior painting of the cylindrical hollow body 25a,
- c) printing or painting of the cylindrical hollow body 25a on the outside
- d) cutting off the upper edge of the cylindrical hollow body 25 a for the exact molding of the
collar 16 of thecan opening 15 and - e) Production of the
upper can portion 13 with theshoulder portion 14 and with the can opening 15 with thecollar 16.
Bei dem zuletzt genannten Fertigungsvorgang e) zur Erstellung des oberen Dosenabschnitts 13 mit dem Schulterbereich 14 und mit der Dosenöffnung 15 mit dem Kragen 16 wird die Vorrichtung 20 nach Anspruch 11 oder 12 verwendet, wodurch auch der andersartige Formgebungsbereich 17 des oberen Dosenabschnitts 13 anformbar ist. Folglich ähnelt dieses modifizierte Herstellungsverfahren der Spraydose 10 dem bekannten Herstellungsverfahren von Spraydosen aus dem Stand der Technik. Nur der Fertigungsvorgang e) unterscheidet sich durch die Verwendung der erfindungsgemäßen Vorrichtung 20. Hierdurch wird der optimierte Herstellungsprozess für die aus dem Stand der Technik bekannten Spraydosen nicht verändert. Folglich entstehen auch keine zusätzlichen Kosten für die Herstellung der Spraydose 10 mit dem Formgebungsbereich 17. An dieser Stelle muss ergänzt werden, dass die Reihenfolge der Fertigungsvorgänge a) bis e) des zuvor genannten Verfahrens nicht auf die dargestellte Reihenfolge festgelegt ist, sondern auch variieren kann. Ebenfalls ist es möglich, dass ein Fertigungsvorgang unterbrochen wird um einen anderen Fertigungsvorgang durchzuführen. So ist aus dem Stand der Technik bekannt, den Fertigungsvorgang e) für den Fertigungsvorgang d) zu unterbrechen.In the latter manufacturing process e) for creating the
Vorteilhafterweise wird bei dem erfindungsgemäßen Verfahren der Fertigungsvorgang a) zur Fertigung eines fast zylindrischen Hohlkörpers 25a mit dem Boden 12 durch ein kostengünstiges Tiefzieh-Verfahren erreicht. Insbesondere ist hier an das bereits erwähnte Verfahren des Rückwärtshohlpressens zu denken. Somit kann auch die Anformung des oberen Dosenabschnitts 13 mit dem Formgebungsbereich 17 durch ein einfaches Pressverfahren realisiert werden.Advantageously, in the method according to the invention, the manufacturing process a) for producing an almost cylindrical hollow body 25a with the bottom 12 is achieved by a cost-effective deep-drawing process. In particular, the already mentioned method of backward hollow pressing is to be considered here. Thus, the molding of the
Ebenfalls ist es von Vorteil, wenn der Fertigungsvorgang e) zur Erstellung des oberen Dosenabschnitts 13 mit dem Formgebungsbereich 17 der letzte Fertigungsvorgang im Herstellungsprozess von unbefüllten Spraydosen 10 darstellt. Nach diesem Fertigungsvorgang e) werden die erstellten Spraydosen c) durch einen großen Spannriemen gebündelt und stapelweise zum Abtransport in ein Abfüllunternehmen bereitgestellt. Zu diesem Zweck ist es ratsam die Spraydosen 10 derart zu gestalten, dass sich die Form der Spraydosen 10 beim Bündeln, d. h. die Spraydosen stehen dicht nebeneinander, gegenseitig ausgleicht, da ansonsten das Bündel nach oben oder unten dicker wird und so den Halt durch den Spannriemen verlieren würde.It is likewise advantageous if the production process e) for the creation of the
Es bleibt noch zu bemerken, dass die hier dargestellten Ausführungsform der Spraydose 10 sowie der Vorrichtung 20 nur beispielhafte Verwirklichungen der Erfindung sind. Diese ist jedoch nicht darauf beschränkt. Es versteht sich, dass die dargestellten Formen und Teile der Erfindung auch in anderen Ausführungen und Konstruktionen vorhanden sein können, die über ähnliche Eigenschaften verfügen, wie diejenigen, die hier beschrieben sind. Ebenfalls wird nicht zwischen einer Spraydose und einer Sprühdose unterschieden.It remains to be noted that the embodiment of the
