Abstract
Abstract A stand for receiving a tubular writing pen which comprises an insertion opening, a sealing element of elastically deformable material disposed below the insertion opening and adapted to come into a sealing engagement contact with the free end of the writing tube of an inserted tubular writing pen. The sealing element (4) has a bearing area for contact with a writing tube (12) that is convex curved in the direction toward said insertion opening of the stand (1, 2) and is deformable away from said insertion opening by contact with the tube. The stand further is characterized by an elastically deformable restraining element (5) which is provided between said sealing element (4) and said insertion opening, and adapted to engage against an inserted tubular writing pen (10, 11, 12).

Claim 1
Independent Claim
193 words
A stand for receiving a tubular writing pen, comprising a stand with an insertion opening and a sealing element of elastically deformable material disposed within said stand and below said insertion opening, said sealing element adapted to come into a sealing engagement contact with the free end of the writing tube when the barrel of the tubular writing pen is inserted, characterized in that the sealing element (4) further comprises a tube segment, with a central axis diposed substantially at a right angle to the direction of pen insertion, said tube segment having a bearing area for contact with a writing tube (12) that normally is convex curved in the direction toward said insertion opening of the stand (1, 2) and is deformable away from said insertion opening by said contact, and further characterized by an elastically deformable restraining element (5) which is provided between said sealing element (4) and said insertion opening, and adapted to engage against the barrel of an inserted tubular writing pen (10, 11, 12), so as to hold said pen in a rest position, with said writing tube substantially, locally deforming a bearing area of said sealing element.

A stand for receiving a tubular writing pen, comprising a stand with an insertion opening and a sealing element of elastically deformable material disposed within said stand and below said insertion opening, said sealing element adapted to come into a sealing engagement contact with the free end of the writing tube when the barrel of the tubular writing pen is inserted, characterized in that the sealing element (4) further comprises a tube segment, with a central axis diposed substantially at a right angle to the direction of pen insertion, said tube segment having a bearing area for contact with a writing tube (12) that normally is convex curved in the direction toward said insertion opening of the stand (1, 2) and is deformable away from said insertion opening by said contact, and further characterized by an elastically deformable restraining element (5) which is provided between said sealing element (4) and said insertion opening, and adapted to engage against the barrel of an inserted tubular writing pen (10, 11, 12), so as to hold said pen in a rest position, with said writing tube substantially, locally deforming a bearing area of said sealing element.
Claim 3
Dependent Claim
47 words
A stand according to claim 1, characterized in that said restraining element (5) further comprises an elastically deformable insert, with a central opening having a boundary area which comprises oblique, bevelled restraining lips (6), adapted to exert a "barb-like" contact about a surface of an inserted pen.
