Patent number: 9873551Abstract: A method for producing a partly transparent body with a color gradient, include: providing a transparent first casing having a first joint surface on a protrusion and including an encased object; providing a second casing which is not completely transparent and which has a second joint surface in a recess. The shape of the protrusion and the shape of the recess correspond to each other; and combining the first casing and the second casing by inserting the protrusion into the recess and melting the first joint surface of the first casing with the second joint surface of the second casing. A pressure force and a temperature are applied to the first joint surface and the second joint surface such that the first joint surface of the first casing transitions into the second joint surface of the second casing in a visually seamless manner, followed by a removal of material.Type: GrantFiled: January 17, 2013Date of Patent: January 23, 2018Assignee: Montblanc-Simplo GmbHInventors: Manfred Martens, Dietmar Podszuweit

Patent number: 8343405Abstract: The invention relates to a production method for incorporating an object into a multi-part, transparent casing. According to the method, an object is aligned on a first joint surface of a first casing part and is pressed into said part using a second casing part with a second joint surface. The first joint surface of the first casing part and the second joint surface of the second casing part are then fused by pressure and temperature, forming a region between the casing parts that is devoid of a visible seam.Type: GrantFiled: September 18, 2006Date of Patent: January 1, 2013Assignee: Montblanc-Simplo GmbHInventors: Dietmar Podszuweit, Manfred Martens, Holger Wuttke
