WRITING INSTRUMENT AND METHOD FOR MANUFACTURING WRITING INSTRUMENT

A method for manufacturing a writing instrument includes inject molding a cushion spring of the writing instrument to form the cushion spring as one piece, and axially pushing out the cushion spring from a molding die set. The cushion spring elastically supports a tip of the writing instrument in an axial direction to a barrel of the writing instrument. The forming of the cushion spring includes forming a plurality of apertures in the cushion spring, one of the apertures being relatively arranged with another one of the apertures by rotations of angles at 90 degrees about the axial direction on an outer peripheral surface thereof, and forming a plurality of displacement regulating protrusions, one of the protrusions being relatively arranged with another one of the protrusions by rotations of angles at 90 degrees about the axial direction.

ULTRA-HIGH FLOW STYRENE ACRYLONITRILE COPOLYMER COMPOSITIONS

Thermoplastic molding composition comprising (A) 40 to 80 wt.-% SAN copolymer (S/AN-ratio 78:22 to 65:35, Mw 80,000 to 250,000 g/mol); (B) 20 to 60 wt.-% SBC block copolymer (monovinylarene 61 to 64 wt.-%) comprising conjugated diene/monovinylarene tapered polymer blocks; and (C) 0 to 5 wt.-% additives and/or processing aids (C); exhibiting ultra-high melt flow with good mechanical, thermal and optical properties, a process for its preparation and its use for the production of bulky and/or thin walled articles.

Feeding pencil

A feeding pencil includes a main body including a main body barrel having a tubular shape, a front barrel detachably engaged with the main body barrel, and a cartridge disposed in the front barrel to receive a drawing material. The cartridge includes a tubular portion provided on a rear side of the cartridge, the main body includes an insertion portion provided on a front side of the main body and configured to be engaged with the tubular portion. When the cartridge is tilted from the main body, an engagement between the tubular portion and the insertion portion is released.

MULTI-FUNCTION WRITING INSTRUMENT COMPRISING A LEAD-HOLDER SYSTEM
20210078353 · 2021-03-18 · ·

A multi-function writing instrument comprises a body extending in an axial direction, at least two writing elements arranged inside the body, each writing element comprising a writing head able to take up a retracted position in which the writing head is stowed in the body and a writing position in which the writing head protrudes from the body, one of the writing elements being a lead-holder system comprising a lead-holder mechanism and a lead container, the lead container comprising a side opening for inserting leads.

KNOCKING-TYPE WRITING INSTRUMENT EQUIPPED WITH ERASER
20210001661 · 2021-01-07 ·

A knocking-type writing instrument has a writing refill, such as a pencil lead or an ink cartridge, that is advanced by knocking a knocking member, and an eraser held by an eraser holder disposed at a rear part of the knocking member. When the writing instrument is inclined so that the eraser side faces downward, a control pin provided in the eraser holder and a movable stopper drop by their own weights along a sliding groove of the knocking member. When the control pin drops a predetermined distance and enters a circumferential locking groove provided at a rear end of the sliding groove, detachment of the control pin is prevented by the stopper, and the eraser holder is unable to retract to the inside of the knocking member. In this state, a radial projection on the control pin abuts a rear end face of the knocking holder, whereby the knocking member is locked and can no longer be knocked, and feeding of the writing refill is prevented.

MULTI-FUNCTION WRITING INSTRUMENT COMPRISING A LEADHOLDER SYSTEM

A multi-function writing instrument comprises a body extending in an axial direction and a radial direction, and having at least two writing elements arranged inside the body, each writing element comprising a writing head and a button, at least one button extending in the radial direction through a window and allowing the writing element to be moved between a retracted position in which the writing head is retracted into the body and a writing position in which the writing head projects from the body, and one of the writing elements being a leadholder system comprising a leadholder mechanism and a lead container, the button of the leadholder system comprising a lead-insertion channel extending in the axial direction.

A writing instrument includes a barrel, a tip, and a cushion spring that elastically supports the tip in the axial direction to the barrel. The cushion spring is formed as one piece by injection molding, the cushion spring includes an aperture on its outer peripheral surface, and a displacement regulating protrusion that protrudes and extends into the aperture along the axial direction. The protrusion prevents the cushion spring from compression beyond a prescribed length.

Writing implement with magnetic component

A writing implement having a magnetic component is disclosed. The writing implement may be a pen, pencil, marker, highlighter, or other type of writing implement, and may include a writing tip, a reservoir for providing a writing fluid, a housing, and at least one magnetic component. The magnetic component may be sized and shaped so that it can be at least partially enclosed within the housing. The magnetic component may include one or more magnets and may be movably coupled to the housing to allow for alignment of the magnets with a ferromagnetic surface.
