Abstract: A refill adaptor for use in ball point pens essentially comprising a main body (10), comprising of a front part (15) and a rear shank portion (20). The front part (15) and said rear shank portion (20) are rigidly coupled together with a ring member (25); and said main body (10) having a capillary tube (40) throughout its length. The said front part (15) is provided with a front housing (35) for holding the refill tip (55) provided with a ball point (65) for smooth writing, said capillary tube being provided with a ink channel, the internal diameter of which is selected to be about 0.8 mm and the outer diameter of said capillary being selected as about 1.8 mm for easy flow of ink from ink reservoir to said ball point (65).

Abstract: The dispenser has a rotary dispenser roller mounted on a reservoir with a telescoping handle. The dispensing head preferably has a valve in its supply channel to control and stop dispensing of cream, lotion, gel or liquid fluids for application to the body surfaces. The dispensing head is angled to conveniently apply fluids to most body surfaces. The dispensing head may carry tools thereon for working with the dispensed fluids.

Abstract: A mechanism for automatically adjusting the chamber length in a writing instrument to accommodate refills of different lengths. The mechanism comprises at least first and second elements operably engaged with each other. When contacted by a refill, the second element automatically moves from a first position associated with a first chamber length to a second position associated with a second chamber length. A biasing member may releasably hold the second element in the first position. In one embodiment third element is fitted within the second element, and is operably and movably engaged with the first and second elements. When contacted by a refill, the third element automatically moves from a first position associated with a first chamber length to a second position associated with a second chamber length. A method of using an automatically-adjusting refill seat mechanism is also disclosed.

Abstract: A writing instrument having an adaptable refill is provided as well as a method for refilling any one of many commercially available writing instruments sold by various manufacturers. The adaptable refill includes a refill body and a variety of components attachable to the refill body in various orders depending on the writing instrument in which the adaptable refill is incorporated. The adaptable refill with the components may be purchased by a consumer and may fit any of the available writing instruments produced by various manufacturers. The components are constructed and designed to secure to the refill body of the adaptable refill in various orders or various arrangements to incorporate the adaptable refill into any one of many commercially available writing instruments.

Abstract: An improvement for a writing instrument consists of an elastomer spacing element disposed within the interior of the writing instrument. The improved writing instrument accepts ink cartridges that are within a range of lengths. Relatively short cartridges are held in place and prevented from independent movement by the spacing element. Conversely, relatively lengthy ink cartridges cause the spacing element to be compressed.

Abstract: An aqueous ball point ink composition comprising a key aqueous ball point ink composition comprising coloring materials consisting of (pigment and pigment dispersant) and/or precolored emulsion resin, water-soluble organic solvent, pseudoplastic imparting agent and water and cross-linked polyacrylate salt in a proportion of about 0.05-0.5% by weight based on the amount of said key aqueous ball point ink composition.

Abstract: An adaptable length refill system and method are provided for replacing a refill in a pen housing. The refill is capable of adapting to any one of a number of available pen housings. To this end, a length of tubing is provided having a hollow core. At least one identifier is provided to identify a length of the tubing necessary to be removed to refill one of the available pens. A packaging card may be provided that is capable of holding the length of tubing and further having a scale thereon indicative of the length of tubing necessary to remove to refill one of the available pen housings. Alternatively, extension members may be added to increase the length of the tubing for insertions of an appropriate length refill into a specific pen housing.

Abstract: An adapter device is provided for varying the length of a ball point pen refill cartridge to enable the cartridge to be used in a variety of ball point pen housings. The adapter consists of a barrel which slips over the distal end of a refill cartridge and is securely connected to the cartridge by a channel formed in the barrel. The barrel comprises detachable sections which are removed as necessary so that the cartridge with the adapter attached barrel sections is substantially equal in length to the exhausted refill cartridge. The channel permits air to flow to the ink cartridge, enabling ink to be flow easily from the cartridge.

Abstract: A ball-point writing instrument in which dislodging of the rotating ball as a result of accidental droppage on a hard surface is prevented by employing an ink reservoir construction designed to prevent propagation of a travelling pressure step in the column of ink above the rotating ball.
