摘要:
The invention relates to a pen comprising a cartridge (10), a retaining sleeve (12) for housing the cartridge at least partially, a locking device (14) that can be actuated by a twisting motion for interlocking the cartridge (10) and the retaining sleeve (12) and a cap (16) for protecting the cartridge. According to the invention, said cap (16) can be displaced axially in relation to the locking device from a first operating position, in which it can be rotated relative to the locking device, into a second operating position, in which it is rotatably coupled to the locking device. The invention is characterised in that the cartridge (10) can be displaced axially in relation to the locking device (14), at least by a length that is equal to the distance between the first and the second operating position of the cap.

A capless, retractable marking instrument (10) has an airtight cavity incorporated in a housing portion (14). The airtight cavity has a chamber portion (30), a wiper seal (34) at one end of the chamber portion (30) and a seal portion (32) at the opposite end of the chamber portion (30). The seal portion (32) is positioned at the forward nib end of the marking instrument (10). The seal portion (32) has an aperture (116) defined by a cross-slit construction that includes two interconnecting linear slits (118, 120). The linear slits (118, 120) define flaps (122) which flex outwardly and back corresponding to the direction of travel of the nib portion (48) of the marketing instrument (10). The flaps (122) roll outwardly when the nib portion (48) is in the extended position and when the nib portion (48) is retracted the flaps (122) gently wipe any excess ink from the nib portion (48) and return to a closed, sealed position to maintain an airtight barrier in the cavity thereby substantially eliminating evaporation of the ink through the nib portion (48).

A twin type stick-shaped material extending container comprised of a base sleeve (3), two rotary guide sleeves (6,7), two traveling bodies (10,11) and two rotation prevention means. The first and second rotary guide sleeves are inserted into the concave inner end portions of the base sleeve (4,5). The first traveling body has a first stick-shaped material (22) receiving base slidably fiting in the first rotary guide sleeve and the second traveling body has a second stick-shaped material (23) receiving base slidably fiting in the second rotary guide sleeve. The first traveling body is inserted in the second traveling body. The two rotary guide sleeves are capped with inner caps (20A,21A) and outer caps (20B,21B) are detachably attached to said first and second inner caps.
摘要:
A correction fluid dispenser comprising a body member (2) adapted to retain correction fluid, a barrel member (12) received by the body member (2), a core portion (24) extending axially of the body (2) and barrel (12) members, and tip seal member (34) disposed in a recess (28) in the core portion (24) and spring biased toward an orifice (38) in the barrel member (12) to block the orifice (38) and prevent flow of fluid therethrough when not in use. The tip seal member (34) being retractable against the spring bias to permit fluid flow through the orifice (38) when in use. The above arrangement requires a strong spring bias to block the orifice (38) when not in use. However, the strong spring bias is difficult to overcome when in use. Inadvertent actuation could also occur with the above structure. The solution to the above problem is to enable the body (2) and barrel (12) members to move the core portion (24) relative to the tip seal member (34) until contact, and thereby the tip seal member (34), into the orifice (38) in blocking, non-retractable position.
