Abstract

The present invention relates to pacifiers of silicone rubber, which consist of an outer cover and a filler material.

Description

Die vorliegende Erfindung betrifft Beruhigungssauger aus Siliconkautschuk, die aus einer Außenhülle und einem Füllmaterial bestehen.The present invention relates to soothers made of silicone rubber, which consist of an outer shell and a filling material.

Beruhigungssauger können aus den verschiedensten Mate­rialien und unterschiedlichsten Konstruktionen gemacht werden, wozu in der Vergangenheit hauptsächlich nur Naturlatex zur Verfügung stand, während in neuerer Zeit Siliconkautschuk stärker bevorzugt wird.Soothers can be made from a wide variety of materials and different constructions, for which only natural latex was mainly available in the past, while more recently silicone rubber is more preferred.

Der Vorteil des Siliconkautschuks liegt insbesondere in dem hervorragenden Alterungsverhalten, der leichten Handhabung beim Reinigung und Sterilisieren, der hohen Transparenz zur besseren Kontrolle der Sauberkeit, der einfachen Verarbeitung auf Spritzgußmaschinen und vieles mehr.The advantages of silicone rubber are, in particular, the excellent aging behavior, the easy handling when cleaning and sterilizing, the high transparency for better control of cleanliness, the easy processing on injection molding machines and much more.

Üblicherweise wurden bisher die Beruhigungssauger aus Naturlatex oder aus Siliconkautschuk in einer Hohlform mit Wandstärken bis zu ca. 2 mm gefertigt, wozu ein Material der Shore A - Härte zwischen 30 und 60 einge­setzt wurde. Größere Wandstärken wurden deshalb nicht gewählt, da andernfalls sich der Beruhigungssauger zu hart anfühlte und von den Kleinkindern nicht mehr ange­nommen wurde; massive Beruhigungssauger aus diesem Material waren wegen der selben Gründe nicht gewünscht.So far, the soothers have been made of natural latex or silicone rubber in a hollow mold with wall thicknesses of up to approx. 2 mm, which is why Shore A material between 30 and 60 was used. Larger wall thicknesses were therefore not chosen, since otherwise the pacifier felt too hard and was no longer accepted by the small children; massive pacifiers made of this material were not wanted for the same reasons.

Da aber die Kraft, die zur Zerstörung eines Saugers allgemein notwendig ist, proportional mit der Schicht­dicke steigt, liegt es nahe, aus Sicherheitsgründen möglichst stabile und damit dickwandige Sauger zu fertigen; mit den zur Verfügung stehenden Materialien war dies aber nicht durchführbar, da ansonsten keine ausreichend weiche und elastische Sauger erhältlich waren.However, since the force that is generally required to destroy a suction cup increases proportionally with the layer thickness, it makes sense to manufacture suction cups that are as stable and therefore thick-walled as possible for safety reasons; however, this was not feasible with the available materials, as otherwise no sufficiently soft and elastic suction cups were available.

Durch die Erfindung wird ein Beruhigungssauger zur Verfügung gestellt, die einerseits die guten Eigen­schaften des hochweiterreißfesten und relativ harten Siliconkautschuks mit denen eines extrem weichen Siliconkautschuks in sich vereinigen.The invention provides a pacifier that combines the good properties of the highly tear-resistant and relatively hard silicone rubber with those of an extremely soft silicone rubber.

Beruhigungssauger für Kleinkinder aus Siliconkautschuk, bestehend aus Außenhülle und Füllmaterial, dadurch ge­kennzeichnet, daß die Außenhülle aus einem hochweiter­reißfesten Siliconkautschuk mit einer Shore A-Härte von 30 bis 60 besteht und wobei diese Außenhülle mit einem weichen Siliconkautschuk mit einer Shore A-Härte von weniger als 5 gefüllt ist und eine chemische und/oder mechanische Bindung an der Grenzfläche zwischen Außen­hülle und Füllmaterial besteht.Soothers for toddlers made of silicone rubber, consisting of outer shell and filler material, characterized in that the outer shell consists of a highly tear-resistant silicone rubber with a Shore A hardness of 30 to 60 and this outer shell with a soft silicone rubber with a Shore A hardness of less than 5 is filled and there is a chemical and / or mechanical bond at the interface between the outer shell and filler.

Gegenstand der Erfindung ist also ein Sauger der beson­ders strapazierfähig ist auf Basis von Siliconkautschuk, wobei wie bisher der Sauger zunächst als Hohlkörper aus hochweiterreißfestem Siliconkautschuk im Shore A-Härte­bereich von 30 bis 60 in Wandstärken um 1 mm gefertigt wird und anschließend mit einem speziellen additionsver­netzenden Siliconkautschuk extrem niedriger Shore A-­Härte gefüllt und durch Temperatureinfluß zur Vulkani­sation gebracht wird; hierbei erfolgt eine gleichzeitige chemische und mechanische Verbindung zum anderen Kautschuk.The subject of the invention is therefore a suction pad that is particularly hard-wearing based on silicone rubber, whereby, as before, the suction pad is initially manufactured as a hollow body made of highly tear-resistant silicone rubber in the Shore A hardness range from 30 to 60 in wall thicknesses of around 1 mm and then with a special addition-crosslinking silicone rubber extremely low Shore A hardness is filled and caused to vulcanize by the influence of temperature; this creates a simultaneous chemical and mechanical connection to the other rubber.

Nach den bisher üblichen Verfahren werden die hohlen Siliconkautschuk-Beruhigungssauger aus peroxidisch ver­netzendem oder additionsvernetzenden Siliconkautschuk über Preßverfahren oder Spritzgußverfahren hergestellt, wobei es sich um Einkomponenten- oder Zweikomponenten-­Kautschuk handeln kann.The hollow silicone rubber pacifiers are produced from peroxide-crosslinking or addition-crosslinking silicone rubber by pressing processes or injection molding processes, which can be one-component or two-component rubber.

Durch die zusätzliche Füllung derartiger Hohlkörper, wobei deren Wandstärke jetzt reduziert werden kann, mit einem extrem weichen Siliconelastomeren können die beim Kauen auftretenden lokalen Überbeanspruchungen, wie Ein­drücken, Einkerben, Einschneiden, durch gleichmäßige Ablenkung der auftretenden Kräfte auf die gesamte rest­liche Oberfläche soweit reduziert werden, daß eine mechanische Zerstörung durch Kauen praktisch unmöglich wird.Due to the additional filling of such hollow bodies, the wall thickness of which can now be reduced, with an extremely soft silicone elastomer, the local overstressing that occurs during chewing, such as indentation, notching, cutting, can be reduced as far as possible by evenly deflecting the forces that occur onto the entire remaining surface. that mechanical destruction by chewing becomes practically impossible.

Ein weiterer Vorteil des erfindungsgemäßen Saugers ist, daß derartige geschmacklich an sich neutrale Füllungen mit diversen Geschmacksstoffen, wie Aroma von Früchten, Milch, Schokolade und dergleichen leicht versetzt werden können und damit von den Kleinkindern noch besser ange­nommen werden; die hierfür erforderlichen Konzentratio­nen der Aromastofe liegen bei unter 0,5 Gew.-%.Another advantage of the teat according to the invention is that fillings of this kind, which are neutral in terms of taste, with various flavors, such as the aroma of fruits, milk, chocolate and the like, can be easily added and are thus even better accepted by toddlers; the concentrations of the aroma substances required for this are below 0.5% by weight.

Das zur Füllung erforderliche Siliconelastomer wird auf Basis eines vinylhaltigen Polysiloxanes, eines Organohy­drogensiloxanes, verstärkend wirkenden SiO₂ -Füllstoffen und eines Katalysators, gegebenenfalls in Gegenwart eines Verzögerers hergestellt:The silicone elastomer required for filling is produced on the basis of a vinyl-containing polysiloxane, an organohydrogensiloxane, reinforcing SiO₂ fillers and a catalyst, optionally in the presence of a retarder:

Das vinylhaltige Polysiloxan hat die allgemeine Struk­tur

Figure imgb0001
worin R¹, R², R³ und R⁴ Alkylgruppen mit bis zu 8 Koh­lenstoffatomen, Arylgruppen und Vinylgruppen bedeuten können, maximal aber 2 Vinylgruppen nur pro Molekül enthalten sind und n die Kettenlänge des Polymer dar­stellt, so daß Viskositäten zwischen 0,1 und 300.000 Pa's bei 20°C erhalten werden.The vinyl-containing polysiloxane has the general structure
Figure imgb0001
 wherein R¹, R², R³ and R⁴ can mean alkyl groups with up to 8 carbon atoms, aryl groups and vinyl groups, but a maximum of 2 vinyl groups are only contained per molecule and n represents the chain length of the polymer, so that viscosities between 0.1 and 300,000 pa's at 20 ° C can be obtained.

Das Organohydrogensiloxan, welches in einer Menge von 0,1 bis 50 Gew.-Teile, bezogen auf 100 Teile vinylhal­tiges Polyisloxan eingesetzt wird, entspricht der Formel

Figure imgb0002
wobei R ein Alkylrest mit bis zu 8 Kohlenstoffen, ein Arylrest oder ein Fluoralkylrest mit 3 bis 8 Kohlen­stoffatomen ist, p größer oder gleich 3 ist und
o + p so variiert werden, daß das Polymer eine Viskosi­tät von 0,005 bis 0,1 Pa's bei 25°C hat.The organohydrogensiloxane, which is used in an amount of 0.1 to 50 parts by weight, based on 100 parts of vinyl-containing polyisloxane, corresponds to the formula
Figure imgb0002
 wherein R is an alkyl radical with up to 8 carbons, an aryl radical or a fluoroalkyl radical with 3 to 8 carbon atoms, p is greater than or equal to 3 and
o + p are varied so that the polymer has a viscosity of 0.005 to 0.1 pa's at 25 ° C.

Der Katalysator ist eine Platinverbindung und wird in Konzentrationen von 1 bis 250 ppm eingesetzt; die Füll­stoffe werden in Mengen von 0 bis 200 Teile eingesetzt.The catalyst is a platinum compound and is used in concentrations of 1 to 250 ppm; the fillers are used in quantities of 0 to 200 parts.

Die Herstellung des Saugers kann in an sich bekannter Weise erfolgen.The suction cup can be produced in a manner known per se.
