Abstract: A personal care implement, such as an oral care implement, that includes a body containing a supply of a fluid. A flow barrier is positioned with a first surface adjacent to the supply of fluid and a second surface opposite the first surface. The flow barrier allows flow of the fluid through the flow barrier for application to a biological surface when the flow barrier is compressed and prevents or inhibits flow of another fluid that is in contact with the second surface of the flow barrier through the flow barrier in a static state. In certain embodiments, the fluid in the supply may have a first viscosity and a first surface tension and the another fluid may have a second viscosity and a second surface tension such that one of the first and second viscosities and one of the first and second surface tensions are different from each other.

Abstract: A fluid supply apparatus with leakage protection. The apparatus includes a housing defining a storage cavity having a total volume including a fluid portion and a gas portion. The storage cavity extends along a cavity axis from a first end to a second end. A capillary member is fluidly coupled with the fluid. A vent tube having a primary vent passageway and a plurality of vent apertures is located in the storage cavity. The primary vent passageway forms a pathway from the vent apertures to the external atmosphere. Fluid cannot flow through the vent apertures at ambient temperature and pressure equilibrium. The vent apertures may be located and arranged on the vent tube such that irrespective of vertical and angular orientation of the housing relative to a gravitational vector at least one of the vent apertures is in spatial communication with the gas.

Abstract: A liquid supply apparatus with leakage protection. The apparatus includes a housing defining a storage cavity having a total volume including a liquid portion and a gas portion. The storage cavity extends along a cavity axis. A capillary member is fluidly coupled with the liquid to transport the liquid to the external atmosphere. The apparatus includes a plurality of vents that prevent liquid from flowing therethrough while permitting air to pass therethrough. A hub component is mounted within the storage cavity and it includes a plurality of radial vent passageways extending between the storage cavity and a primary vent passageway, which in turn forms a pathway to the external atmosphere. The vents may be located and arranged such that irrespective of inclination and rotational orientation of the housing relative to a gravitational vector at least one of the vents is in spatial communication with the gas.

Abstract: A writing instrument includes a barrel, a refill assembly, and a refill plug assembly that is quick to release from the barrel and quick to re-attach to the barrel when changing a refill assembly. The refill plug assembly is quickly secured to the barrel of the writing instrument and quickly released from the barrel of the writing instrument through a twisting and/or pushing action that may require less than one full turn to disengage from the barrel and to re-attach to the barrel, thus expediting replacement of the refill assembly.

Abstract: A writing instrument includes a shell, an ink reservoir disposed in the shell and a writing tip section that is provided on the shell from which ink from the ink reservoir is applied to a substrate. The writing tip section includes a writing tip and an ink feed assembly for delivering ink from the ink reservoir to the writing tip through capillary action. The writing tip is flexible and a flexible cover with the shape of a fountain pen nib is provided for supporting the flexible writing tip.

Abstract: A writing instrument includes a magnetically actuated locking assembly for releasably securing a first component, such as a cap, to a second component, such as a barrel. The magnetically actuated locking assembly includes a first magnet and at least one second magnet, the magnetic fields of which actuate and release a mechanical lock between the first component and the second component.

Abstract: A writing instrument includes a nose section that is releasably connected to a barrel housing portion that contains an ink reservoir, in the form of a replaceable cartridge, for holding ink for delivery to a writing nib. The nose section is releasably connected to the barrel housing portion with a magnetic-mechanical connection assembly to allow easy access to the replaceable cartridge.

Abstract: A writing instrument includes a nose section that is connected to a barrel housing portion that contains an ink reservoir for holding ink for delivery to a writing nib. A cap may be releasably secured to the barrel housing portion with a first magnetic-mechanical connection assembly to cover the nib to protect the nib from damage and to prevent ink evaporation. Similarly, the nose section may be releasably secured to the barrel housing portion with a second magnetic-mechanical connection assembly for accessing a replaceable ink cartridge that includes the ink reservoir.

Abstract: A highlightable mixture, such as an ink, including a colored pigment, an eradicable colorant, and a non-eradicable colorant; a kit including the highlightable mixture and an eradicator fluid; an colorant complex including a colorless or substantially colorless eradicable dye selected from the group consisting of diarylmethane derivatives, triarylmethane derivatives, and methine dyes, and a colored pigment; and methods of applying an eradicator to at least a portion of a marking made with a highlightable mixture, are described herein.

Abstract: A fluid control system for writing instruments, correction fluid dispensers and self contained paint brush and paint reservoirs is disclosed. The fluid control system includes two filters or reservoirs, including a hydrophobic filter/reservoir and a hydrophilic filter/reservoir. The hydrophobic and hydrophilic elements may be spaced adjacent to and in abutting engagement with each other or a gap or space may be disposed therebetween. The hydrophobic element is disposed adjacent to the fluid reservoir (i.e., ink, correction fluid, paint reservoir or other water based fluid) and the hydrophilic element is disposed adjacent to the applicator tip or brush.

Abstract: An improved fluid control system for a paint brush or applicator system that includes a flexible barrel-type reservoir is disclosed. The disclosed valve systems may be of a ball-valve type, a trumpet-type or a duck-bill type. The valve or control systems help the user regulate the flow of fluid from a flexible barrel reservoir to a brush or applicator tip by adequately restricting flow in response to squeezing pressure applied by the user to the flexible barrel reservoir.

Abstract: The disclosure is generally related to a decoder system and, more particularly, to a decoder system comprising a coding composition, a decoding composition and optionally, an erasing composition. The disclosure also provides decoder writing instrument systems comprising a coding writing point in fluid communication with a coding composition, a decoding writing point in fluid communication with a decoding composition and optionally, an erasing writing point in fluid communication with an erasing composition.
