Abstract: A writing instrument having a writing part, having a writing tip, and having a protective cap which protects, the writing tip and is releasably connectable to the writing part. For the releasable connection between the cap and writing part, the writing part has several connecting structures, each with a connecting region which is curved in an ellipsoidal, ball-shaped manner, such as balls or semi-spheres, and the cap has an internal thread on the inside. The internal thread of the cap and the connecting structure of the writing part are positioned and aligned with each other in such a manner that, in each case with the cap in a state fastened on the writing part, the connecting region of the respective connecting structure engages completely or in part in a or the thread of the internal thread.

Abstract: A writing instrument includes a nose section that is connected to a barrel housing portion that contains an ink reservoir for holding ink for delivery to a writing nib. A cap may be releasably secured to the barrel housing portion with a first magnetic-mechanical connection assembly to cover the nib to protect the nib from damage and to prevent ink evaporation. Similarly, the nose section may be releasably secured to the barrel housing portion with a second magnetic-mechanical connection assembly for accessing a replaceable ink cartridge that includes the ink reservoir.

Abstract: A marking implement for marking activities such as marking of a drill hole or indicating a cutting/sawing edge, and includes a marking pen having a pen housing and an application reservoir held in a axially fixed manner therein and a protective cap with an elongate interior for partially accommodating the marking pen. The marking pen has a gripping region and, adjoining it, a thinner neck region, on which a nib is formed at the free end. The cap has an interior section for partially accommodating the gripping region and a narrower interior section for accommodating the neck region. Furthermore, a fastening clip is disposed on the outer surface of the cap. The clip is integrally formed on the protective cap with a fixed end in a region adjacent to the opening and, from there, tapers substantially to the end of the cap that faces away from the opening.

Abstract: A writing instrument cap (3) has a clip (23) as a separate part and is characterized in that a clip attachment (21e) to which the clip is fitted is projectively formed on the outer periphery of the writing instrument cap, the clip attachment has a vent hole (25) penetrating between the interior and exterior of the writing instrument cap, and in the state where the clip is set to the clip attachment, the clip covers the vent hole and creates a clearance between the clip interior and the clip attachment so as to establish an air passage (24) that communicates between the vent hole and the outside.

Abstract: A cap positioning construction for positioning and mounting a cap to a barrel, includes a triangular notch formed in a step face of a barrel on which the end of a cap abuts, and a triangular extension formed at the end of the cap. The triangular extension extends toward the notch and matches the notch 12e. By fitting the extension in the notch, the cap is positioned relative to the barrel when the cap is mounted on the barrel.

Abstract: A pen includes a vertical pen barrel, a mounting seat mounted fixedly on a top end of the pen barrel, and a molded metal unitary unit. The unit includes a pen top disposed swingably on the seat, and a pen clip extending integrally and downwardly from the pen top. The clip has a clamping end, which is movable relative to the pen barrel between a clamping position, where the clamping end presses against the pen barrel, and a releasing position, where the clamping end is spaced apart from the pen barrel. A biasing unit biases the clip to the clamping position.

Abstract: An applicator, especially for applying nail varnish, is associated with a closing cap with a reservoir for keeping the coating member moist. Located in the closing cap is a closing element which, when the closing cap is pulled off the applicator, closes the space containing the reservoir in order to prevent the reservoir from drying out.

Abstract: A writing instrument having a closure cap assembly (1, 2, 3, 4 and 5) which can be placed in a sealing manner on the writing tip (20), whereby a positive engagement with an indentation in the writing tip is established via an elastically deformable finger (8), when the closure cap is in place on the writing tip. On the inner face of the arm (8), oriented toward the writing tip (20), at least one cam face (13) is located in a chord plane of the circle forming the closure cap opening. Whereupon a twisting of the entire mounted closure cap assembly (1, 2, 3, 4 and 5) brings the cam face (13) into engagement with a correspondingly formed wedge face (27) of the writing tip (20), so that the arm (8) is pivoted radially outward, and the closure cap can be removed.

Abstract: A tubular nib having a beak-shaped section at one end of a tube, a slit formed in the beak-shaped section, and a slit-widening inhibiting section having a radius of curvature larger than that of the tubular part of the tubular nib at least at the section across the innermost end of the slit in the beak-shaped part of the tubular nib.

Abstract: A device for fastening the cap upon the rear portion of the body of a fountain pen or another writing article, comprising an annular member disposed inside said body and provided with axial extensions, each of which is provided with a part arranged to protrude, through a corresponding perforation of said body, with respect to the outer surface of the body itself in order to cooperate with the inner surface of said cap, is described. Each of said extensions is deformable by flexion such as to generate, in consequence of said flexion, pressures between said parts and the inner surface of the cap when said cap is put on said body.
