Abstract

Disclosed is a nipple, pacifier, drinking beak, or teething ring (1) comprising a base (8) that is made of at least one polymer material, and a transparent, colorless layer (9) which is a made of a latex and/or a polymer solution and is applied to the outside of the base by means of a dipping process.

Description

The invention relates to a nipple, pacifier, a drinking spout and teething ring and to methods for their preparation.

Nutritional teat, hereafter referred to as "teat", are attachments made of soft elastic material for attachment to the opening of a bottle for babies. Babies can take liquid food out of the bottle through the teat's drinking hole.

Soothers, hereafter referred to as "pacifiers", are soft elastic rubber parts with a mouth plate.

Spouts are soft-elastic attachments for drinking bottles used by older children and adults.

Teething rings are called annular bodies made of a more or less soft material that infants and toddlers can bite during toothing.

Suckers, pacifiers, drinking spouts and teething rings are primarily made of natural latex and silicone rubber, but also of thermoplastic elastomers. Existing products, with no added dyes, because dyes could leach out of the products during use, adversely affect the infant or toddler, which would be inadmissible due to applicable food law and product-specific requirements.

Nevertheless, it would be desirable to provide vacuum cleaners, pacifiers, drinking spouts and teething rings, for example, to make it easier to distinguish products from each other or for aesthetic reasons.

Based on this, the object of the invention is to provide a colored nipple, pacifier, drinking spout or teething ring which, when used by the infant or the toddler, releases no dyes. Furthermore, the invention has for its object to provide a method for producing such a nipple, pacifier, a drinking spout or a teething ring.

The object is achieved with respect to the product by a sucker, pacifier, a drinking spout or a teething ring with the features of claim 1. Advantageous embodiments of the nipple, pacifier, the drinking spout or the teething ring are specified in subclaims.

• einen farbigen Grundkörper und
• eine den Grundkörper umgebende durchsichtige Außenschicht, hergestellt aus einem Latex und/oder einer Polymerlösung, jeweils ohne Farbstoff.

The sucker invention, pacifier, the drinking spout or the teething ring comprises from the inside out

• a colored base body and
• a transparent outer layer surrounding the base body, made of a latex and / or a polymer solution, each without dye.

It can be used both natural and synthetic latex.

In the teat, pacifier, drinking spout or teething ring according to the invention, a colored base body is enclosed by an outer layer of an undyed, more or less transparent material. This layer effectively prevents the mucosal contact of the infant or toddler to the colored body and ensures that even by the predictable mechanical stress no color pigments can pass to the mucosa or food. Thus, the requirements for these commodities are met. Nevertheless, the colored base body is visible through the transparent outer layer so that for the first time colored suckers, pacifiers, drinking spouts or teething rings are provided, ie their color deviates from the color of the non-dye-added natural rubber latex or synthetic latex. For example, the products can be provided in intensive blue, orange, green or red.

Natural rubber latex is widely used as a material for suckers, pacifiers, drinking spouts and teething rings and the production of the outer layer of natural rubber latex is easy to implement in terms of production technology. It is to be expected that this will be widely accepted by the user. The use of synthetic latex for the outer layer has the advantage that in Latexallergikern latex allergies can be avoided. A suitable synthetic latex is, for example, polyisoprene latex. Although polyisoprene does not have the same strength as natural rubber latex. However, when using a base made of a suitable material, sufficient strength of the entire product can be achieved. In particular, it is possible to produce the base body from natural rubber latex. The outer layer of synthetic latex prevents the user from coming into contact with latex protein from the base body.

In principle, it is possible to carry out the nipple, pacifier, drinking spout or teething ring as a solid body, wherein the nipple or the drinking spout is provided with a passage for the liquid, which connects the drinking hole with the opening to the drinking bottle. According to one embodiment, the colored base body is hollow. This is particularly advantageous for the production of soft or compliant suckers, pacifiers, drinking spouts and teething rings and enables material savings.

According to one embodiment, the base body has a transparent, colorless inner layer applied by dipping from a natural and / or synthetic latex and / or a polymer solution, each containing no dye.

For the main body different materials are considered, for a nipple or pacifier particularly soft or elastic materials and harder materials can be selected for a teether. According to one embodiment, the main body consists of a composition containing a natural rubber latex or a synthetic latex. In this embodiment, the body has the same properties as the outer layer, so that the softness or elasticity of the product does not differ from the conventional products, which are made entirely of natural rubber latex or synthetic latex. In addition, a base made of natural rubber latex or synthetic latex is particularly firmly connected to an outer layer of the same material.

The color of the body can be obtained in various ways. According to one embodiment, the base body is made of a dye-containing composition. The dye is thus mixed into the composition from which the base body is produced, so that a self-colored base body is achieved.

• einen Grundkörper, der aus verschiedenen, auch farbigen Polymermaterialien (z.B. Naturkautschuk, Silikonkautschuk, thermoplastische Elastomere) mit verschiedenen Verfahren hergestellt werden kann (z.B. Tauchen, Spritzguß, Extrusion) und
• einer außen durch Tauchen aus einem Latex und/oder Polymerlösung aufgebrachten durchsichtigen, farblosen Schicht und
• bei einem hohlen Grundkörper erforderlichenfalls einer innen durch Tauchen aus einem Latex und/oder Polymerlösung aufgebrachten durchsichtigen, farblosen Schicht.

Furthermore, the application relates to a nipple, pacifier, drinking spout or teething ring comprising

• a body made of different, even colored polymer materials (eg natural rubber, silicone rubber, thermoplastic Elastomers) can be prepared by various methods (eg, dipping, injection molding, extrusion) and
• an externally applied by dipping of a latex and / or polymer solution, transparent, colorless layer and
• in the case of a hollow base body, if necessary, a transparent, colorless layer applied internally by dipping from a latex and / or polymer solution.
