Abstract

Abstract A felt-tip pen (1) for writing on posters or the like is inserted into an ink pot for refilling and keeping. In order to prevent the outer sides of the felt-tip pen from becoming soiled with ink, the felt-tip pen has an axial groove (12) parallel to the felt-tip (10) entered by a collar (22) that surrounds the opening (21) of the ink pot (20) when the felt-tip pen is inserted through the opening. This groove is designed in an intermediate piece (5) that bears the felt-tip and that is in turn inserted onto the cup-shaped end (3) of the handle with a second groove (11 ) of the same size as the first but oriented in the opposite direction. The felt-tip may thus be inserted on both sides onto the handle (2) and into the ink pot and at the same time it is well sealed in the ink pot.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 135 words
A device for writing on posters and the like, comprising an inkwell and a felt-tip pen, with the felt-tip pen including a handle member and a felt tip secured therein which has one end thereof extending out of the handle member, characterized in that a groove (12) concentric with the longitudinal axis of the felt tip (10) is provided, said groove encompassing the felt tip (10) immediately behind the protruding end of the felt tip (10) and being open in the direction of said end, thus enabling the felt-tip pen (1) to be introduced into an opening (21) of the inkwell (20), in which a collar (22) encompassing the opening (21) engages said groove (12), the felt tip (10) encountering an ink-impregnated absorbent body (30) before the collar (22) reaches the bottom of the groove.
Claim 2
Independent Claim 135 words
A device for writing on posters and the like, comprising an inkwell and a felt-tip pen, with the felt-tip pen including a handle member and a felt tip secured therein which has one end thereof extending out of the handle member, characterized in that a groove (12) concentric with the longitudinal axis of the felt tip (10) is provided, said groove encompassing the felt tip (10) immediately behind the protruding end of the felt tip (10) and being open in the direction of said end, thus enabling the felt-tip pen (1) to be introduced into an opening (21) of the inkwell (20), in which a collar (22) encompassing the opening (21) engages said groove (12), the felt tip (10) encountering an ink-impregnated absorbent body (30) before the collar (22) reaches the bottom of the groove.
Claim 3
Dependent Claim 23 words
A felt-tip pen as claimed in claim 1, characterized in that the depth of the groove (12) is a multiple of its width.
Claim 4
Dependent Claim 117 words
A felt-tip pen as claimed in claim 1, characterized in that the felt tip (10) is held in an intermediate piece (5) exchangeably attached to the handle member (2) and is in abutting engagement with a reservoir structure inside said handle member (2), that the intermediate piece (5) is comprised of an inner and an outer sleeve (6, 7) concentrically arranged with each other, said sleeves (6, 7) being interconnected by a central link member (8) to produce two equal grooves (11, 12) extending concentrically with the longitudinal axis of the felt tip (10), and that the handle member (2) has a cup-shaped portion (3) inserted into one of the grooves (11, 12) for locking engagement therein.
Claim 5
Dependent Claim 38 words
A felt-tip pen as claimed in claim 3, characterized in that in the inner sleeve (7) in the area of the link member (8) an inwardly extending projection (9) is provided holding the inserted felt tip (10) captive.
