Patent number: 5076721Abstract: A writing instrument cap having a tubular lower section suitable to embrace a cylindrical body of a writing instrument. An upper section of the cap is formed by a central tubular core and is closed on its top. The upper section receives a writing point of the writing instrument to make an airtight seal. The outer surface of the central tubular core has a plurality of outwardly projecting radial fins whose outer edges define a prolongation of an outer wall of the lower tubular section. The circumference of those fins accounts for less than one-half of the circumference of this prolongation of the outer wall. A plurality of clearances permit the rectilinear flow of air through the cap. Channels are formed between adjoining radial fins, and the cross-sectional area of the clearances is in excess of one-half of the total cross-sectional area between the outer surface of the central tubular core and the prolongation of the outer wall.Type: GrantFiled: March 21, 1990Date of Patent: December 31, 1991Assignee: Dobell, S.p.A.Inventor: Domenico Belmondo

Patent number: 5061105Abstract: A removable cap attached to a writing instrument in an insertion manner for preventing ink from evaporating from the writing instrument, includes: a hollow cylindrical cap main body provided with a trunk portion in which at least one ventilating hole is provided and a hollow cylindrical inner cap fixedly mounted in the cap main body. The cap having been detached from the writing instrument permits open air to axially flow through the interior space of the cap through a front axial opening of the cap ventilating holes in the inner cap a space defined between the inner cap and the cap main body and a ventilating hole formed in the peripheral wall of the cap main body at a position under the pocket clip of the marking pen.Type: GrantFiled: December 15, 1989Date of Patent: October 29, 1991Assignee: Mitsubishi Pencil Co., Ltd.Inventor: Takashi Isoda

Patent number: 5054949Abstract: In a writing implement cap, especially for ball point pens, having at least one air channel penetrating the front face, an air channel is shaped so as to extend axially and radially and is located in the region of the otherwise closed front side. Apart from that the axially extending segments of the air channel are bounded by at least one baffle wall extending transversely or by at least one step or disk and are connected through at least one radial aperture with additional axial segments arranged to be offset or with the inside space of the cap so as to form continuous through air channels.Over and above that the cap wall, the end wall and the baffle wall or the step or the steps or the disk or the disks are to be designed so as to form one piece with each other.Type: GrantFiled: January 26, 1990Date of Patent: October 8, 1991Assignee: J.S. Staedtler GmbH & Co.Inventor: Friedrich Heger

Patent number: 5051015Abstract: A protective cap for a writing, drawing or applicator element comprises an outer casing portion and within same a closure cap portion which has a cover portion for sealingly covering over the applicator member of the implement. The cap portion is connected to the casing portion by means of ribs which define between them through openings through which the interior of the cap is in fluid communication with the exterior thereof. The through openings are of an overall cross-section of at least 5 mm.sup.2 in order at least to reduce the risk of asphyxiation if the cap is unintentionally swallowed. The ribs are disposed in the region of the cover portion of the cap portion and are extended in the axial direction of the cap over the cover portion, whereby the through openings are oriented in particular in a radial direction.Type: GrantFiled: June 12, 1989Date of Patent: September 24, 1991Assignee: Schwan-Stabilo Schwanhausser GmbH & Co.Inventor: Gerhard Moeck
