Definitions

  • the invention relates to a device and a method for designing condoms and the designed condoms themselves.
  • a condom (or condom) is usually a latex cover which is striped over the erect male member prior to sexual intercourse to avoid both pregnancy and sexually transmitted diseases. Condoms come in different colors, sizes and shapes. A recent development is condoms for women, although they have found little use.
  • Condoms serve as the only contraceptive in addition to the protection against unwanted pregnancies as a reliable protection against sexually transmitted diseases such as AIDS, hepatitis, syphilis, gonorrhea (gonorrhea) or the HPV virus, a widespread viral infection, which is considered a high risk factor for the Emergence of cervical cancer is considered. Because of this dual function, the relatively simple handling, the lack of side effects - with the exception of latex allergies - and their relatively high safety condoms meanwhile form the most commonly used protective measure during sexual intercourse. For these reasons, it is highly desirable that condoms are used by the at-risk groups. The provision of optically attractive as well as inexpensive condoms is a suitable measure to increase the likelihood of using condoms.
  • vulcanization In conventional condom production, cleaned flasks are dipped several times in latex milk and then each layer is dried. The latex milk adheres to the glass flask after each immersion, which is then heated at approximately 100 degrees Celsius in an oven. This "drying" of the mandrels is referred to as vulcanization.
  • the process of vulcanization produces elastic rubber from solid rubber. So elastic that you can inflate condoms like balloons.
  • the finished condom is pushed down with a gentle jet of water from the glass flask.
  • the condoms are washed and dried in a dryer at 70 ° C. Condoms are powdered to avoid sticking together.
  • the material for the condom production is latex milk, which consists mainly of natural rubber and water.
  • a production method for usable, common safety standards fulfilling condoms is provided with decoration, wherein a glass bulb is used, which is immersed at least once in liquid latex and a decorative element of latex during the manufacturing process directly on the glass bulb, on or under a latex layer or between a first and second latex layer of the latex dip bath is applied and by a subsequent vulcanization step, the decorative element and the respectively present (s) latex layer (s) are joined together.
  • the condom production methods of the present invention include manufacturing processes in which decorations are applied from liquid latex during the production process, fonts or motifs are transferred by means of a stamping or gravure printing method, or prefabricated decorative elements are used.
  • the decoration elements are applied from liquid latex during the manufacturing process by means of a high-pressure process or the air-brush process.
  • the image and / or the writing are applied directly to the surface of the glass bulb or a first latex layer of the condom to be produced during the production process.
  • the second layer in the case of the direct application of the decoration on the glass flask of the first layer, one uses colorless, transparent latex milk. After vulcanization, a condom is created that consists of a uniform, welded-together latex layer with images and fonts and that complies with DIN EN ISO 4074. - A -
  • Printers using the high pressure principle can generally be sprayed with anything that is liquid and has low viscosity, such as ink, paint, certain oils, or even uncured adhesives and resins. For this reason, the high pressure process is also suitable for spraying a liquid latex milk in a defined pattern or as a typeface.
  • the second latex layer is dried and then all layers of la- tex are vulcanized.
  • the decoration is applied directly to the glass bulb using adapted continuous-jet printers, this is dried immediately and then a transparent latex layer is applied from a latex dip. This method can be significantly thinner condoms, since only a complete latex layer is present produce.
  • the decorations to be applied to the condom consist of the same material as the condom itself.
  • the condom retains its properties and protects against pregnancies or sexually transmitted diseases is suitable and thus meets the requirements of DIN EN ISO 4074, it is necessary that decorative elements are not incorporated or incorporated into the material of the condom after production, but rather during the development process. This ensures that the various layers can bond together during vulcanization and that the condom consists of a fully vulcanised latex cover.
  • Liquid latex milk can be sprayed not only by the high-pressure process, but also by small spray guns, which are commonly referred to as "Air Brush” - in English “air brush”.
  • the airbrush process thus also makes it possible to apply liquids to surfaces without producing any contact between the spray gun and the surface.
  • step 3 The difference in the method of manufacturing a decorated condom using the airbrush technique to the high pressure process is that in step 3) of the manufacturing process outlined above, stencils are placed around the glass bulb and one or more movable spray guns apply a different colored latex milk. It is also conceivable that different colors are sprayed by different spray guns and each spray gun sprayed only defined areas of a stencil, so that the result is a multi-colored decorative layer. Furthermore, several templates can be placed around the glass bulb with the first latex layer several times in succession. According to the invention, a manufacturing method is further provided in which the decoration is applied by a stamping process directly on the glass bulb or a first latex layer.
  • the stamp used in this method is a roller made of rubber or a comparable material.
  • the roller has the same outer diameter as the glass bulb for immersion in the latex baths. On the surface of the roller there are elevations, which are a kind of "negative” of the applied motifs or fonts.
  • This roller further referred to as a punch, rotates against a second roller, with the liquid, differently colored latex, based on the latex dip Surveys is applied.
  • the roller which acts as a stamp
  • the motif and / or writing are applied to the first dried latex layer or directly onto the glass flask. This happens because the glass bulb and the punch are brought into contact with each other and both rotate in an opposite direction to each other at an identical speed.
  • stamping pressure has been applied directly to the glass flask, after a single immersion of the glass flask it is vulcanized into a liquid, transparent latex milk.
  • condoms can be produced with a thinner material thickness. If the pressure is applied between two latex layers, vulcanization takes place after the second immersion of the glass bulb.
  • Another manufacturing method according to the invention makes use of intaglio printing.
  • the glass bulb which was previously dipped at least once in a bath with liquid latex, passes an embossing device.
  • the pattern is transferred into the latex layer (s).
  • the embossing device is a roller, which is brought into contact with the glass bulb and rotate the glass bulb and embossing roll at the same speed in the opposite direction.
  • a condom is produced in which a pattern is embossed.
  • An alternative to applying or creating the decoration of liquid latex milk is the use of prefabricated solid decorations or lettering from latex. These preferably consist of an extremely thin latex layer of up to 0.04 mm and are produced by a suitable method, such as casting or pressing.
  • the decorative elements are already prefabricated from solid latex before they are introduced into the material of the condoms by the method according to the invention.
  • Decorative elements prefabricated from solid latex are preferably transferred to the glass bulb or a first latex layer by means of a further rotating roller, as in the case of the stamping or printing process.
  • solid latex decorations are used, they are applied to the glass flask just prior to the first immersion of the glass flask so that the glass flask only has to be immersed once in the bath of liquid latex .
  • the solid latex decoration can also be introduced between a first and a second latex layer.
  • this production process also concludes with a vulcanization step.
  • the decorative elements used in all production methods according to the invention preferably have a different color than the latex layers, which are applied by means of latex dipping baths on the glass bulb. If the glass bulb is immersed twice in a latex bath, then the latex of the second dip bath, ie the outer latex layer, is preferably transparent. This ensures that the decorations are also clearly visible. It is according to the invention but also expressly provided that the decorations are made of fluorescent latex material, which are visible only when they are excited, for example, by suitable light, such as UV light.
  • the decorations that is to say characters, logos and / or graphics, consist of a very thin latex layer and "fuse" or crosslink with the actual latex layers of the condom by means of vulcanization, since no other materials than latex are used Despite the design, the condoms according to the invention are still fully usable and fulfill the criteria of the most common safety standards, such as, for example, the international standard DIN EN ISO 4074.
  • Another object of the present invention are condoms, which meet common safety standards and have a decorative design of latex, wherein the decoration is crosslinked by at least one vulcanization step with the latex shell.
  • these condoms are made using the method of the invention.
  • the decoration element consists of a lettering, an image, a logo or a combination thereof. If a condom according to the invention has only one latex envelope made of a latex layer which has been applied to a glass envelope by means of a latex dip bath, the decorative element is arranged on or under the latex layer. In an alternative embodiment, the condom has a latex sheath of two latex layers which have been applied to a glass envelope by means of a latex dip, the decoration element being arranged between the latex layers.
  • the decorative element of a condom according to the invention has a different color than the latex shell, or consists of fluorescent latex.
