Abstract: An applicator has a tubular body containing a liquid to be dispensed. A non-return device is movably disposed in the tubular body rearwardly of and in contact with the liquid for preventing backflow of the liquid. A manually-displaceable piston member is displaceable in the tubular body in a forward direction for pressurizing air admitted into a chamber located in front of the piston member, and a normally closed valve communicates with the chamber and is openable by the force of the pressurized air to apply the pressurized air to the non-return device to urge the non-return device forwardly to thereby pressurize the liquid. A resilient member normally urges the piston member rearwardly to a rear stop position. An air passage communicates the chamber with the exterior of the applicator when the piston member is in the rear stop position, and the air passage is blocked by the piston member during displacement of the piston member in the forward direction.

Abstract: There is provided an applicator comprising a tubular main shaft body containing therein a liquid, a compressive device, disposed at a rear portion of the tubular main shaft body, for compressing the liquid, a non-return device positioned at a rear portion of the liquid and movable along with a decrease of the liquid, and a valve mechanism between the non-return device and the compressive means.

Abstract: A fluid discharge device has a fixed member provided with a hollow cylindrical piston having a normally-closed valve on its upper surface, a press member provided with a hollow cylinder which has a normally-closed valve on its upper surface, and which is fitted slidably around the piston, and a storage chamber formed of a soft material, secured to the lower portion of the fixed member and holding fluid therein. The press member is constantly urged upward by a resilient member provided between the press member and the fixed member, to thereby enable the press member to be pressed down freely. The fluid in the storage chamber is discharged to the upper surface of the press member by pressing the press member in the downward direction, and thereafter releasing the press member.

Abstract: A projectable or push-out type writing instrument cartridge, such as a projectable cartridge for a ball point pen, has a filler impregnated with an aqueous ink, a writing point at its one end, a device for feeding the ink to the writing point, and an end plug mounted in the other end of the cartridge. The plug has an air passage which satisfies a predetermined condition. Preferably, the end plug consists of an inner rod and an outer tube which receives the inner rod in such a manner that the air passage is formed between the rod and the tube. The cartridge is secured in the casing of the instrument, and is projectable to a writing position.

Abstract: A writing instrument comprises a plurality of slots for holding writing implements such as colored leads, the slots being formed radially in the inner wall of a cylindrical body. The instrument comprises a guide tube mounted coaxially within the cylindrical body and having an opening which can be aligned any one of the slots, a cover plate provided at the opening of the guide tube and adapted to be tilted by the operation of a knock cap, and a chuck provided to the front end of the guide tube. A selected writing implement in the slot is allowed to drop by gravity into the guide tube from the tilted cover plate and then is clamped by the chuck.
