Abstract: An applicator device, particularly suited for mascara, may deliver high or low viscosity liquids or semi-liquids, and contains a valve controlling flow between a product reservoir, an intermediate pooling area, and a product dispensing chamber. The arrangement prevents backflow to the product reservoir, precluding contamination of the product supply. Product delivery from the product dispensing chamber is from one of several methods. In one method, a plurality of prongs each comprise a conduit to the product dispensing chamber and thereby allow for dispersed product delivery from the prong tips. Alternatively, there may be one or more openings on the applicator head being interconnected to the dispensing chamber, which permits product to extrude between the rows of prongs and thereby be applied to a receiving surface. A third embodiment combines the two methods along with alternating height prongs to more effectively apply mascara onto all sides of a user's lashes.

Abstract: A fluid applicator which makes application work easy because liquid splash outside the container body is prevented by opening the valve by removing the cap such that the liquid is supplied directly to the applicator member from the container body. The valve body incorporated in a sealed chamber is pressed against the shouldered seal portion to bring the sealed chamber into communication with the connecting passage such that the liquid discharged from the container body is allowed to flow into the sealed chamber through a hollow shaft member and is further led through a connecting passage into the applicator attachment hole to which the applicator member is attached.
Abstract: A writing instrument has an ink reservoir, a nib and a feeder which temporarily stores ink which is pushed out of or pulled into the ink reservoir. The ink reservoir communicates with the nib through an ink supplying passage. The feeder chamber communicates with the atmosphere through an atmosphere communicating passage and with the ink reservoir through a capillary flow passage. The cross-sectional area of the capillary flow passage is small enough to hold ink in the capillary flow passage due to a surface tension of the ink. When the pressure in the ink reservoir due to a temperature change, etc., ink flows in the feeder chamber through the capillary flow passage or is returned from the feeder chamber to the ink reservoir. Since the feeder chamber is hollow, its volume is large and has a simple structure, the feeder can be manufactured easily. A low flow resistance of the capillary flow passage provides good response for compensation for a pressure change.
Abstract: A refillable pen having a writing reservoir for supplying a writing tip with ink and an additional supply reservoir for refilling the writing reservoir by operating a first valve.

Abstract: A brush arrangement, specifically a toothbrush, is provided with a reservoir of cleaning material in its handle. The handle is hollow and provided with an actuatable plunger arrangement which pressurizes the cleaning material so as to force it through a channel and to the brush head. The pressurized cleaning material opens a pressure valve arrangement which exposes a dispensing port through which the cleaning material is dispensed in the vicinity of a plurality of bristles. The dispensing port is opened by the application of a force from the pressurized cleaning material which exceeds a counterforce applied by a resilient device, such as a spring. When the pressure in the reservoir is relieved, such as by reversing the direction of travel of the plunger, the counterforce applied by the spring is sufficient to ensure that the pressure valve closes the dispensing port. In certain embodiments, the brush arrangement is provided with a replaceable brush head.

Abstract: An ink supply system for writing instruments which operate with liquid ink or writing fluid. In order to make uniform the supply of ink or writing fluid independent of environmental influences, and to make possible a longer writing time with one filling, it is proposed to first store the writing fluid in a primary, permanently compressible, non-capillary and large-volume supply chamber. From this primary supply chamber, a small-volume, capillary secondary supply chamber, which communicates with the writing element, is supplied via an auxiliary charging valve which is controllable as a function of need for ink or writing fluid. The filling of the secondary supply chamber can be detected with a sensor, and the auxiliary charging valve can be controlled.
