Abstract: An improved fountain pen (1) comprises a hollow barrel (2) with a longitudinal central axis of extension (X), a nib (3) located at a first longitudinal end (2a) of the barrel (2), an ink reservoir (4) located inside the barrel (2) and designed to feed the ink to the nib (3), a piston (5) able to move axially along the central axis (X) to create a vacuum inside the ink reservoir (4); the ink reservoir (4) also comprising a sac (6) made of deformable material.

Abstract: In the cosmetic storage type applicator having a structure for supplying a cosmetic to an applying part from the interior of a barrel cylinder, a cap removably attached to the front part of the barrel cylinder for covering the applying part and plastic mouthpiece is provided; an inner sleeve having a tapered inside diameter toward the front end is arranged inside the body of cap and integrally formed with the cap body; and the inner peripheral surfaces and from the inner sleeve to the cap body are formed with a smooth surface without any step.

Abstract: The outer surface of an inner cap 3 is fixedly secured to the inner surface of an outer cap 4. In the opened end portion of the inner cap 3, there is formed a rear end shell portion 31 which projects backwardly. On the outer peripheral surface of the rear end shell portion 31, there is provided a ring-shaped outward facing seal portion. In the front end portion of a barrel 6, there is formed a front end shell portion 61 projecting forwardly. In the inner peripheral surface of the front end shell portion 61, there is formed a ring-shaped inward facing seal portion. When a cap 2 is mounted on the pen tip 8 side of the barrel 6, the outward facing seal portion can be closely contacted with the inward facing seal portion in the radial direction.

Abstract: A writing instrument cap (3) has a clip (23) as a separate part and is characterized in that a clip attachment (21e) to which the clip is fitted is projectively formed on the outer periphery of the writing instrument cap, the clip attachment has a vent hole (25) penetrating between the interior and exterior of the writing instrument cap, and in the state where the clip is set to the clip attachment, the clip covers the vent hole and creates a clearance between the clip interior and the clip attachment so as to establish an air passage (24) that communicates between the vent hole and the outside.

Abstract: A writing implement having a cap member is provided and is a direct-flow type (liquid ink type) writing implement including: a barrel cylinder; a holder holding a pen core at a front end of the barrel cylinder and further having inside the barrel cylinder, an ink tank for storing a liquid ink and a collector for temporary retention thereof. The collector, barrel cylinder and ink tank are formed of a clear, transparent material. A mouthpiece at the outer periphery of the holder is formed of a resin material having the same color as the ink held in the ink tank or having the same color as the written ink. The barrel cylinder may have a partition wall, positioned near to the center, on the side (rear side) opposite to the position where the collector is arranged, forming an ink tank in a space inside the barrel between the rear end plate of the collector and the partition wall.

Abstract: A pen cap for closing on a ball-point pen to prevent ink leakage, the pen cap including a cap body, a sealing cap covered on the cap body, and a ball valve mounted inside the cap body within the sealing cap and moved between inside ribs in the cap body and inside ribs in the sealing cap. Closing the pen cap on the pen causes excessive air to pass through an air passage formed by gaps among the inside ribs to the outside of the pen cap via an exhaust hole on the sealing cap, and the air passage is closed when the writing tip of the pen is engaged into a tapered hole on one cylindrical rod projecting from the ball valve.

Abstract: Basic configuration of a cap is as follows. When the end face of an elastic seal cylinder arranged in a cap for a writing instrument is caused to abut against and come into tight contact with the end portion of the mouth piece of a barrel cylinder to hermetically seal a point assembly and the opening portion of an air groove, first, the distal end of the point assembly is hermetically sealed with the bottom of the seal cylinder. The inner opening edge portion of the seal cylinder fits on the conical portion of an ink reservoir or of a point assembly support from an intermediate portion of the conical portion, and is gradually attached to the barrel cylinder while widening the opening portion of the seal cylinder in the radial direction.

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: An applicator, especially for applying nail varnish, is associated with a closing cap with a reservoir for keeping the coating member moist. Located in the closing cap is a closing element which, when the closing cap is pulled off the applicator, closes the space containing the reservoir in order to prevent the reservoir from drying out.

Abstract: A device for preventing the drying of the nib of a cartridge type pen, wherein a cartridge type ink container provided with a nib and used to directly contain ink or contain an absorbent loaded with the ink and to supply the ink to the nib through a relaying material, a vent hole is made in a nose cone of the ink container at a position close to the nib, packing is provided between the outside peripheral surface of the ink container and a penholder at the position close to the vent hole to prevent the vent hole from communicating with the outside air, the nib is provided with elastic material such as rubber and plastics in the cap, a blind hole is made in the lower end surface to insert the nib, the opening of the blind hole is shut at the front end of the nose cone of the holder or the front end of the nose cone of the ink container to cut off the communication of the inside of the blind hole with the outside air, and both used to cut off the communication of the vent hole with the outside air by means of th

Abstract: A modular writing instrument cap system is disclosed, in which each individual cap comprises an elongated tubular portion having an open end and a closed end. Near the closed end the cap is internally provided with a seal member adapted to seal with a writing instrument holding quick-drying ink. Near the open end, the tubular portion is internally provided with a catch for removably securing the cap on a writing instrument. Externally on the closed end, the cap is provided with a transversely-oriented open ended tubular barrel. The barrel is configured to receive an internally threaded sleeve, terminator rings and screws which thread towards one another through the rings into the opposite ends of the sleeve in order to hold the assembly together and secure a bail to it. The ends of the barrel and corresponding ends of the terminator rings are cooperatively notched to accommodate the legs of the bail.
