Abstract: A capless retractable sealed marking instrument has a sealed chamber incorporated in a marker casing. The sealed chamber includes a chamber, a wiper ring, and an annular rim and a seal portion with a cross-slit aperture defining surfaces or flaps which are moved out of contact by a linearly-advanced marker nib to open the seal for extension of the marker nib. The configuration of the disk provides positive sealing force between the lateral sealing surfaces of the seal flaps. In the storage position, the seal effectively closes to protect and preserve the associated component. In a preferred embodiment, a housing member includes a closing member. The closing member engages the disc to seal the slit in the closed position when the associated component is in storage. The disc may include tabs that engage the closing member.

Abstract: A tape dispensing device is comprised of a means for rotatably supporting a roll of tape. A means for adhering to the tape and pulling the tape forwardly is positioned forwardly of the supporting means. The adhering means and pulling means is rotatably supported. A motor means is provided for imparting rotation to said adhering and pulling means. Means for cutting the tape means is positioned forwardly of said adhering and pulling means. A switch means is provided for actuating the motor continuously while said actuating means is engaged. Also a shaping means is positioned above the path of travel of the tape to urge the tape against the adhering and pulling means, the adhering and pulling means including a set of feed rollers. The shaping means is positioned between a pair of adjacent feed rollers, the lowermost edge of the shaping means being positioned below the uppermost edge of said pair of adjacent feed rollers forming a structural indentation in said tape.

Abstract: According to one embodiment of the present invention, a scent dispenser is provided that includes a fan and a scent cartridge, the scent dispenser dispensing scent when a flow of air is directed over a fragrant or aromatic substance in the scent cartridge.

Abstract: A capless retractable sealed marking instrument has a sealed chamber incorporated in a marker casing. The sealed chamber includes a chamber, a wiper ring, and an annular rim and a seal portion with a cross-slit aperture defining surfaces or flaps which are moved out of contact by a linearly-advanced marker nib to open the seal for extension of the marker nib. The configuration of the disk provides positive sealing force between the lateral sealing surfaces of the seal flaps. Retraction of the marker nib draws the flaps back into the sealed chamber configuration to protect the marker nib and cartridge from atmospheric degradation.
