Abstract: 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.

Abstract: A mechanical pencil having a cylindrical barrel (1) and a sheath (2) in axial relationship is disclosed. A spiral member (4) in fixed relationship with the sheath and in axially sliding relationship with the barrel for a predetermined range engages a slider (7). The slider is in fixed relationship with a push feed type writing unit and slides axially within a predetermined range within the barrel (1) as allowed by a guide (3). First spring means is provided to urge the spiral member in a forward direction when the writing unit is positioned axially such that it is contained within the barrel (1). As the writing unit is moved from its rearmost position within the barrel (1) to a protruding position by rotation of the spiral member (4), a second spring means urges the spiral member in a rearward direction, forming a gap between the barrel (1) and the sheath (2).

Abstract: A chuck mechanism incorporated in a mechanical pencil has a plurality of chuck elements in a longitudinal confronting relation. The chuck elements have a pivotal support or fulcrum at their opposing rearward portions so that the elements are pivotable about the fulcrum. The fulcrum is formed proximal to the rear end and distal to the front end jaw portions of the chuck elements. When an axial force is applied to the chuck elements, the jaw portions of the chuck elements are opened to release lead engagement thereby. The rear portion relative to the fulcrum is a portion where an axially forward thrust added thereto is converted to a radially inward thrust to the rear portion.

Abstract: An automatic lead advancing mechanism for a mechanical pencil has at its writing point a lead guide tube which is movable axially against a clamping member to cause radially movable components of the clamping member to clamp the lead therein during the writing position of the pencil. The lead guide tube moves axially inwardly against a force exerted by a compression spring interposed between the clamping member and a thrust member, a portion of which is engaged by the lead guide tube and another portion of which has a beveled surface engaging a correspondingly beveled surface on the clamping member. The co-acting beveled surfaces exert both axial and radial forces to the clamping member.

The pencil has a lead holder slidably mounted lengthwise within a casing, a lead guide tube slidably mounted within the casing together with the lead holder, a lead feeding device mounted movably within the casing for feeding the lead into the lead guide tube, and a device mounted movably within the casing for locking rearward movement of the lead feeding device. The lead can be advanced by merely releasing a writing pressure which was applied by the writing tip onto a piece of writing paper.

Abstract: In a lipstick container of basically orthodox type, comprising a body and sleeve with co-operating axial and helical slots to impart axial movement to a lipstick-bearing cup on relative rotation, there is a breakable web across one of the slots, preferably the axial one, acting to obstruct inadvertent movement of the cup so that the container can be shipped and displayed for sale with the lipstick projecting from the body and visible through a transparent cover. Subsequent deliberate action by the user to retract or advance the lipstick will break the web.
