A press structure for a press type stationery, having mounting board (1), a button (400) and a resilient piece. The mounting board has a recess (11). A position limiting block (12) is provided at the front surface of the mounting board in this recess. A closed loop sliding track is formed between outer walls of the position limiting block and inner walls of the recess. The resilient piece has a spring (2) and a resilient rod (3). The position limiting block has a first inclined surface (122) and a second inclined surface (123). End portions of the first and second inclined surfaces are at one side of the resilient rod; upper ends of the first and second inclined surfaces are at another opposite side of the resilient rod. A contact part (4) positioned within the sliding track is provided at an upper end portion of the resilient rod.

A handheld implement, configured for example as a writing-instrument, having a shaft that has at least two shaft parts which are releasably connectable together via a plug-in coupling, which have a coupling unit at each front end of the shaft parts. Each coupling unit has a slide that is held immovably in a guide hole open on a face side in the associated shaft part and protrudes beyond the guide hole with a slide portion, the free end of the slide portion is formed as a latching fork that has a latching opening between two fork arms, that the slide portion bears a latching protrusion on its inner side behind the latching fork in the sliding direction, the coupling unit has a guide sleeve that encloses the slide and is guided movably in the guide hole counter to the restoring force of a spring- or rubber-elastic restoring element, and when the front ends, having the coupling units, of two shaft parts are pressed together, the latching fork of one coupling unit is latchable on the latching protrusion of the other coupling unit with at least one of the guide sleeves being pushed back.

Aqueous hard surface cleaner compositions useful for removing permanent ink are disclosed. The compositions comprise 75 to 99 wt. % of water; 0.1 to 5 wt. % of a monoterpene; 0.1 to 5 wt. % of a C.sub.10-C.sub.17 fatty acid derivative; and 0.1 to 5 wt. % of one or more surfactants. The fatty acid derivative is selected from N,N-dialkyl amides, N,N-dialkyl esteramines, and N,N-dialkyl amidoamines. Preferably, a base such as sodium carbonate or monoethanolamine is also included. The invention includes concentrates comprising the non-aqueous components recited above, as well as other applications for the cleaners and concentrates such as graffiti removers and permanent ink erasers. The combination of a monoterpene and certain fatty acid derivatives, especially fatty N,N-dialkyl amides, unexpectedly enables even dilute aqueous compositions to rapidly decolorize black permanent marker from hard, non-porous surfaces.

An instrument includes a body, at least two modules, each separate from the one or other modules, including an operative portion and being movable relative to the body and, for each module, a mechanism for guiding the translation and rotation of the module along the body, the module being movable relative to the body, successively in translation parallel to a first axis and in rotation about a second axis perpendicular to the first axis and which is rigidly connected to the body, between an inoperative configuration in which the operative portion of the module is housed inside the body and a use configuration in which the operative portion of the module projects from the body. The two modules or two of the modules are arranged on either side of a single arm of the body, which extends along the first axis from a base to an end of the body.

Provided is a coating film transfer tool comprising an external cassette and an internal cassette housed in the external cassette. The internal cassette includes a supply portion configured to supply transfer tape having a coating film on substrate tape. A pressing and transferring portion is configured to transfer the coating film to a film receiving surface by pressing the transfer tape against the film receiving surface, a take-up portion is configured to take up the substrate tape after the coating film is transferred, and a rotation-in-conjunction mechanism is configured to rotate the supply portion and the take-up portion in conjunction with each other. The external cassette includes a button and an elastic member. The pressing and transferring portion sticks out of the external cassette by the button being pressed, and the pressing and transferring portion retracts into the external cassette by the pressing of the button being stopped.

An applicator includes: an applying part on a front portion thereof; a removable cap that totally covers the applying part; a sealing element that seals up a front end portion of the applying part when the cap is fitted; and an inner cap provided inside the cap. The inner cap includes an inner cap body and a hinged cap that is joined to the inner cap body and can abut the inner cap body. The hinged cap has a hollow mounting portion. An engaging portion for fixing the hinged cap is formed inside the cap. When the inner cap having the sealing element held between the inner cap body and the mounting portion is fitted into the interior of the cap, the hinged cap is engaged by the engaging portion inside the cap.
