Provided is a thermochromic writing instrument 1, comprising: a writing body 9, storing a thermochromic ink therein, stored in a barrel 2; an operation body provided in the barrel 2 to be operated to longitudinally move the writing body 9; a nib 91 of the writing body 9 configured to be capable of appearing from a front end of the writing instrument, wherein the writing instrument 1 further includes a friction unit 10, rubbing handwriting in the thermochromic ink and capable of thermally changing the color of the handwriting by frictional heat generated at that time, and at least one clip body 7 as the operation body, the friction unit 10 is provided at a rear end of the barrel 2, and the clip body 7 is provided in an area other than the rear end of the barrel 2.
摘要:
A method of coextruding polymeric materials into multiple layers of desired thickness to form a tubular workpiece. The method includes conveying a first polymeric material through a main extruder and a second polymeric material through a coextruder. The second polymeric material has dispersed therein an amount of electrically conductive particles effective to impart electrical conductivity to the tubular workpiece. The method further includes simultaneously extruding the first polymeric material and the second polymeric material through a coextrusion die to form the tubular workpiece. The tubular workpiece is extruded in the form of one or more outer layers having the first polymeric material and one or more inner layers comprising the second polymeric material. A tubular workpiece prepared by the method of coextruding polymeric materials into multiple layers of desired thickness. A system for coextruding polymeric materials into multiple layers of desired thickness to form a tubular workpiece is also provided.

A liquid applicator device for dispensing an applicator liquid from an applicator liquid container comprising a closure for sealing with the applicator liquid container. A sealing surface is defined in the closure and a valve is disposed within the closure. A spring is located within the closure between a spring retaining step defined in the closure and the valve for biasing the valve into sealing engagement with the sealing surface of the closure for inhibiting the flow of the applicator liquid from the applicator liquid container. A passageway defined in the closure for slidably receiving an applicator tip for engaging with the valve to enable a depression of the applicator tip to displace the valve from the sealing surface of the closure to flow applicator liquid from the applicator liquid container to the applicator tip.
摘要:
The invention relates to a writing instrument including a body (2), a clip (5) and a first projecting member (3) for attaching the clip (5) having a first lateral side (33). The clip (5) includes a bar (53) and the body includes a second projecting attachment member (4) having a second lateral side (43). The second lateral side (43) extends from a base (41) secured to the body (2) to an upper end (43a) from which a projection (44) extends towards the first lateral side (33). The first and second lateral sides (33, 43) and the projection (44) are arranged to provide a cavity (49) under the projection suitable for receiving the bar (53), and to provide a passage (48) suitable for inserting a locking element (61) into a locked position for which it is adjusted between the first lateral side (33) and the barrel (53) of the clip located in cavity (49).

The present invention provides a screw-type writing instrument having an expansion and contraction function in which an outer shaft cam (10) , a cartridge holder (30) and an inner shaft cam (40) are coupled in a double screw manner, so that the expansion or contraction of the writing instrument and the advancing or retracting operation of a pen core (20) can be simultaneously conducted, thus being convenient to use, and which, thanks to the contractible structure, is convenient to carry and hold.
摘要:
Um die Entformung von Gewinden in Kuststoff-Hülsenstücken 1,2,3,4 zu erleichtern und die Herstellungskosten zu senken, wird eine konische Gewindestruktur (α 1 ,α 2 ,t) vorgeschlagen. Bei ihr und bei den diesbezüglichen Formwerkzeugen sind die in translatorischer Richtung z oder -z benachbarten Gewindeelemente 50,60,51,61 radial so beabstandet, daß jedes Gewindeelement beim Entformen E0,E1,E2 oder F0,F1 nur einmal "entrastet", um kein zweites Mal einzurasten.
摘要:
A marker-making kit for assembling a marking device having a user- determined mixture of marking solution is provided. The kit includes a base unit coupled to a marker positioning mechanism and a press mechanism. A mixing tube holder secures a mixing tube used for collecting a desired amount of one or more marker fluids. A mixed marker solution is combined, including any number of different colors of marker fluid, and used to saturate a marker reservoir. The saturated reservoir may then be transferred to a maker barrel positioned near the press mechanism. By applying an amount of force with a marker compression arm, a completed marker is secured, enclosing the marker reservoir inside a marker barrel.
