Abstract:
1. A writing tool including a plurality of cartridges containing volatile marking substances therein and capable of applying said substances onto an article from said cartridges one at a time in response to an input force applied by a user comprising: at least two cartridge members each of which is configured to include one of said cartridges and a tip through which said marking substance contained in said one of said cartridges is applied onto said article; at least one cap member which is configured to change and restore at least one configuration thereof one of directly and indirectly in response to said input force; at least one case member which is configured to define an interior therein and to support at least portions of said cartridge members and at least a portion of said cap member one of directly and indirectly; and at least one actuator member which is configured to actuate at least one of said cap member, cartridge member, and case member in order to change and restore said configuration one of directly and indirectly in response to said input force, wherein said tool defines at least one enclosed space at least a portion of which is defined in said interior and which is configured to be not in fluid communication with an exterior of said tool, wherein said actuator member is configured to restore said configuration and to dispose said tips of all of said cartridge members in said enclosed space when said tool is not in use, and wherein said actuator member is configured to change said configuration, to expose said tip of one of said cartridge members selected by said user out of said enclosed space through said cap member while disposing said tips of the rest of said cartridge members not selected by said user in said enclosed space when said tool is in use, thereby preventing significant evaporation of said substances from said tips of said rest of said cartridge members when said tool is in use, and wherein said cap member changes said configuration and forms at least one opening, wherein said tip of one of said cartridge members selected by said user is exposed to said exterior through said opening, wherein a portion of said cartridge member selected by said user is configured to block a preset portion of said opening, and wherein at least one of said cap member and actuator member is configured to block the rest of said opening, thereby preventing said evaporation from said tips of said rest of said cartridge members when said tool is in use.
