Technisches GebietTechnical field
Die Erfindung betrifft ein stapelbares Besteckteil mit einem Griff mit einer Wandung und einem an den Griff angeformten Funktionselement, gemäss dem Oberbegriff des unabhängigen Patentanspruchs.The invention relates to a stackable cutlery part with a handle with a wall and a functional element molded onto the handle, according to the preamble of the independent claim.
Stand der TechnikState of the art
Bestecke aus Kunststoff, insbesondere Messer, Löffel und Gabeln, sind weit verbreitet, sei es als Wegwerfbestecke für eine einmalige Verwendung oder an Orten, an welchen Kunststoffbestecke aus Gewichts- oder Sicherheitsgründen gegenüber Bestecken aus Metall bevorzugt werden, beispielsweise in Flugzeugen. Da aus Kosten- und Gewichtsgründen die Besteckteile relativ dünnwandig gefertigt werden, wird eine ausreichende Stabilität durch eine entsprechende Formgebung erreicht. Üblich sind beispielsweise Griffe mit T-, H-, S- oder U-förmigem Querschnitt.Plastic cutlery, in particular knives, spoons and forks, are widely used, either as disposable cutlery for one-time use or in places where plastic cutlery is preferred over metal cutlery for weight or safety reasons, for example in aircraft. Since the cutlery parts are made relatively thin-walled for reasons of cost and weight, adequate stability is achieved by appropriate shaping. For example, handles with a T, H, S or U-shaped cross section are common.

Darstellung der ErfindungPresentation of the invention
Aufgabe der Erfindung ist es, stapelbare Besteckteile der eingangs erwähnten Art zur Verfügung zu stellen, welches die oben erwähnten und andere Nachteile nicht aufweist, und insbesondere eine hohe Stapeldichte bei gleichzeitigem minimalem Materialverbrauch erlaubt.The object of the invention is to provide stackable cutlery parts of the type mentioned at the outset, which does not have the above-mentioned and other disadvantages, and in particular allows a high stacking density with at the same time minimal material consumption.
Diese und andere Aufgaben werden gelöst durch ein erfindungsgemässes Besteckteil gemäss dem unabhängigen Anspruch. Weitere bevorzugte Ausführungsformen sind in den abhängigen Ansprüchen gegeben.These and other objects are achieved by a cutlery part according to the invention in accordance with the independent claim. Further preferred embodiments are given in the dependent claims.
Ein erfindungsgemässes Besteckteil besteht aus einem Griff und einem daran angeformten Funktionselement, welches die Verwendung des Besteckteils definiert. Die üblichsten Besteckteile sind natürlich Löffel, Gabel und Messer. Um eine grösstmög liehe Stabilität zu erreichen, ist der Griff des erfindungsgemässen Besteckteils als Wandung mit auf beiden Seiten randständig daran angeordneten Längsrippen ausgestaltet, so dass sich ein im wesentlichen H-förmiger Querschnitt ergibt. Zur zusätzlichen Stabilisierung ist am dem Funktionselement entgegengesetzten Längsende des Griffs auf beiden Seiten der Wandung eine endständige Rippe angeordnet. Die endständige Rippe und die zwei Längsrippen auf den beiden Seiten sind so ausgestaltet, dass beim Stapeln der erfindungsgemässen Besteckteile die endständige Rippe und die Längsrippen der ersten Seite eines Besteckteils formschlüssig in die endständige Rippe und die Längsrippen der zweiten Seite des in Stapelrichtung daran anschliessenden weiteren Besteckteils eingreifen.A cutlery part according to the invention consists of a handle and a functional element formed thereon, which defines the use of the cutlery part. The most common cutlery items are of course a spoon, fork and knife. In order to achieve the greatest possible stability, the handle of the cutlery part according to the invention is designed as a wall with longitudinal ribs arranged on both sides at the edges thereof, so that an essentially H-shaped cross section results. For additional stabilization, a terminal rib is arranged on the longitudinal end of the handle opposite the functional element on both sides of the wall. The terminal rib and the two longitudinal ribs on the two sides are designed such that when the cutlery parts according to the invention are stacked, the terminal rib and the longitudinal ribs of the first side of a cutlery part form fit into the terminal rib and the longitudinal ribs of the second side of the further cutlery part adjoining it in the stacking direction intervention.
Vorteilhaft werden die endständige Rippe und die Längsrippen des Griffs eines erfindungsgemässen Besteckteils so ausgestaltet, dass die Rippen auf der ersten Seite der Wandung bzw. des Griffs auf der Aussenkante, also auf der der Wandung abgewandten Kante der Rippen, eine erste Abschrägung aufweisen. Auf der zweiten Seite der Wandung bzw. des Griffs weisen die endständige Rippe und die Längsrippen auf einer der Wandung zugewandten Innenkante eine zweite Abschrägung auf. Diese vorteilhafte Ausgestaltungsform erleichtert die automatische Zentrierung der einzelnen erfindungsgemässen Besteckteile beim Stapeln. Die Anforderungen an die notwendige Präzision der Fertigung der erfindungsgemässen Besteckteile sind zudem mit solch einer Lösung geringer, was aus Kostengründen vorteilhaft ist.The terminal rib and the longitudinal ribs of the handle of a cutlery part according to the invention are advantageously designed such that the ribs have a first bevel on the first side of the wall or of the handle on the outer edge, that is to say on the edge of the ribs facing away from the wall. On the second On the side of the wall or of the handle, the terminal rib and the longitudinal ribs have a second bevel on an inner edge facing the wall. This advantageous embodiment facilitates the automatic centering of the individual cutlery parts according to the invention when stacking. With such a solution, the requirements for the necessary precision of manufacturing the cutlery parts according to the invention are also lower, which is advantageous for cost reasons.
In einer noch vorteilhafteren Ausgestaltungsform eines erfindungsgemässen Besteckteils ist der Neigungswinkel der zweiten Anschrägung gegenüber der Ebene der Wandung kleiner als der Neigungswinkel der ersten Anschrägung gegenüber der Ebene der Wandung. Dies hat den zusätzlichen vorteilhaften Effekt, dass die Berührungspunkte von aufeinander gestapelten erfindungsgemässen Besteckteilen sich auf die Aussenkante der Rippen der ersten Seite beschränkt. Die einzelnen Teile lassen sich so leichter voneinander lösen, und die Gefahr des Verklemmen ist noch geringer.In an even more advantageous embodiment of a cutlery part according to the invention, the angle of inclination of the second bevel with respect to the plane of the wall is smaller than the angle of inclination of the first bevel with respect to the plane of the wall. This has the additional advantageous effect that the points of contact of cutlery parts according to the invention stacked on one another are limited to the outer edge of the ribs on the first side. This makes it easier to separate the individual parts and the risk of jamming is even lower.

Ausführung der ErfindungImplementation of the invention
Figur 1 erläutert den Aufbau eines erfindungsgemässen Besteckteils 1 anhand eines Querschnitts senkrecht zur Längsachse des Griffs 2 des Besteckteils 1. Auf der ersten 4a und der zweiten 4b Seite der Wandung 4 des Griffs 2 sind randständig Längsrippen 6, 6' angeformt.FIG. 1 explains the construction of a cutlery part 1 according to the invention on the basis of a cross section perpendicular to the longitudinal axis of the handle 2 of the cutlery part 1. On the first 4a and the second 4b side of the wall 4 of the handle 2, longitudinal ribs 6, 6 'are formed at the edges.
Wie aus Figur 1a ersichtlich ist, sind die Längsrippen so ausgestaltet, dass beim Stapeln der erfindungsgemässen Besteckteile 1 , 1' die Rippen 6, 6' der ersten Seite 4a des einen Besteckteils 1 formschlüssig in die Rippen 6, 6' der zweiten Seite 4b des anderen Besteckteils T eingreifen. Das analoge gilt für die im Querschnitt nicht sichtbaren endständigen Rippen.As can be seen from Figure 1a, the longitudinal ribs are designed such that when the cutlery parts 1, 1 'according to the invention are stacked, the ribs 6, 6' of the first side 4a of the one cutlery part 1 fit into the ribs 6, 6 'of the second side 4b of the intervene in another piece of cutlery T. The same applies to the terminal ribs, which are not visible in the cross section.
Die Figuren 2 und 2a zeigen eine weitere Ausgestaltungsform eines erfindungsgemässen Besteckteils 1 , im Querschnitt durch den Griff 2. Die Längsrippen 6, 6' sind senkrecht zur Wandung angeordnet. Die Längsrippen 6, 6' der ersten Seite 4a sind gegenüber den Längsrippen 6, 6' der zweiten Seite 4b nach innen versetzt. Bei Stapeln der erfindungsgemässen Besteckteile 1 , 1' stehen die Längsrippen 6, 6' der ersten Seite 4a des einen Besteckteils 1 auf der Wandung 4 des zweiten Besteckteils 1' auf. Analog können natürlich auch die Längsrippen der zweiten Seite 4b auf der Wandung 4 aufstehend ausgestaltet seinFigures 2 and 2a show a further embodiment of a cutlery part 1 according to the invention, in cross section through the handle 2. The longitudinal ribs 6, 6 'are arranged perpendicular to the wall. The longitudinal ribs 6, 6 'of the first side 4a are offset inwards relative to the longitudinal ribs 6, 6' of the second side 4b. When the cutlery parts 1, 1 'according to the invention are stacked, the longitudinal ribs 6, 6' of the first side 4a of one cutlery part 1 stand on the wall 4 of the second cutlery part 1 '. Analogously, the longitudinal ribs of the second side 4b can of course also be designed to stand up on the wall 4
Die Figur 3 zeigt eine weitere bevorzugte Variante eines erfindungsgemässen Besteckteils 1 , in einem Querschnitt durch den Griff 2. In diesem Fall weisen die Längsrippen 6, 6' der ersten Seite 4a an der Aussenkante 8 eine erste Abschrägung 7a auf, und die Längsrippen 6, 6' der zweiten Seite 4b eine zweite Abschrägung 7b. Vorteilhaft, aber nicht zwingend, ist wie gezeigt der Neigungswinkel α der ersten Abschrägung 7a gegenüber der Ebene der Wandung 4 grösser als der Neigungswinkel ß der zweiten Abschrägung 7b gegenüber der Ebene der Wandung 4. Um Hinterschneidungen zu vermeiden, sollte ß mindestens 90° betragen. Figur 3a zeigt zwei erfindungsgemässe Besteckteile 1 , 1' aus Figur 3 in gestapeltem Zustand. Die Längsrippen 6, 6' der zweiten Seite 4b des Besteckteils 1 liegen nur mit der Innenkante 9 auf der ersten Abschrägung 7a des weiteren Besteckteils 11 auf. In einer alternativen Gestaltungsform können die Neigungswinkel α, ß auch umgekehrt gewählt werden, so dass der Neigungswinkel α der ersten Abschrägung 7a kleiner ist als der Neigungswinkel ß der zweiten Abschrägung 7b.FIG. 3 shows a further preferred variant of a cutlery part 1 according to the invention, in a cross section through the handle 2. In this case, the longitudinal ribs 6, 6 'of the first side 4a have a first bevel 7a on the outer edge 8, and the longitudinal ribs 6, 6 'of the second side 4b a second bevel 7b. As shown, the angle of inclination α of the first bevel 7a with respect to the plane of the wall 4 is greater, but not mandatory, than the angle of inclination β of the second bevel 7b with respect to the plane of the wall 4. In order to avoid undercuts, β should be at least 90 °. FIG. 3a shows two cutlery parts 1, 1 'from FIG. 3 in a stacked state. The longitudinal ribs 6, 6 'of the second face 4b of the cutlery part 1 lying on 7a further cutlery item 1 1, only with the inner edge 9 on the first bevel. In an alternative embodiment, the angle of inclination α, β can also be selected in reverse, so that the angle of inclination α of the first bevel 7a is smaller than the angle of inclination β of the second bevel 7b.
Um bei der Herstellung der erfindungsgemässen Besteckteile aus Kunststoff, beispielsweise mittels Spritzguss, eine einfache Entformung der Besteckteile aus dem Werkzeug zu ermöglichen, sind alle Rippen vorzugsweise so gestaltet, dass sie keinen Hinterschnitt aufweisen.In order to enable the cutlery parts to be easily removed from the mold when manufacturing the plastic cutlery parts according to the invention, for example by means of injection molding, all the ribs are preferably designed such that they have no undercut.
