Abstract: A writing instrument having an automatic sealing structure that may reduce an entire diameter of the writing instrument due to a decrease in a size of a ball shutter, thus to improve grip feeling of a user.

Abstract: A writing instrument having an automatic sealing structure, in which a hinge part of a holder has projection jaws formed thereon having a role of a stopper that can prevent a hinge shaft from being excessively pivoted, thereby more effectively preventing ink from drying out due to complete sealing of the nib.

Abstract: An assembly structure of a writing instrument, in which a sealing module assembly having a pre-assembled module for sealing is detachably attached to a body of the writing instrument, such that a production process may be smoothly performed due to an assembly process of the sealing parts with a difficulty in assembling being previously performed, and defective parts may be separately processed when defects occur in each part due to the separation structure of the body and the sealing module assembly, thereby reducing a defective rate. The assembly structure of a writing instrument, including: a body including a knock part installed therein to be operated by pushing, and a cartridge inserted into a hollow inside thereof; and a sealing module assembly which is detachably attached to a front end of the body, and has modules for sealing and operating installed inside thereof.

Abstract: The present invention has an object to provide a retractable type writing instrument, in which a nib is fixed to a cartridge by means of a nib fixing means, and the nib fixing means has an air circulation passage formed in a coupling part thereof, such that it is possible to prevent the air circulation passage from being exposed, thus to enhance an aesthetic appearance when using the writing instrument, and prevent an occurrence of defective writing by always stably supplying air due to prevention of foreign matters from inflowing into the cartridge. The retractable type writing instrument, including: a body case including a knock part installed therein to be operated by pushing, and a cartridge inserted into a hollow inside thereof; and a nib fixing means coupled to an end of the cartridge so as to connect a nib housed therein with the cartridge.

Abstract: A writing implement, with retractable ends, an upper shaft and lower shaft coupled together and rotatable relative to each other, a cartridge and an eraser holder in an intermediate connection member are simultaneously movable in upward and downward directions. The cartridge having a writing nib; the connection member having a slit; the lower shaft coupled to the connection member, a nib hole for extending/retracting the nib therethrough; the upper shaft having a thread enabling the cartridge to move with the integrated rotation of the connection member and lower shaft; a cam coupled to the upper shaft, having an inner wall with a protrusion; an eraser holder engages the protrusion and slit and rotates in upward and downward directions with the rotation of the connection member and lower shaft; and a ball shutter in the lower shaft to open/shut the nib hole by means of the vertical sliding of the cartridge.

Abstract: A double-ended makeup brush tool having an automatic sealing structure, in which respective brushes provided in opposite ends of a barrel can be selectively and alternately used, so that, when one brush is used, the other brush can be disinfected by a disinfectant inside the barrel, thereby being kept clean. When a user presses the rear end of the cartridge with the finger, the locking protrusion of the cartridge is removed from a rear locking hole of the barrel and is caught by a front locking hole and, in the above state, the brush hole of the barrel is opened by an anti-drying unit and a first brush can be ejected from the barrel through the open brush hole. When the locking protrusion is removed from the front locking hole and is caught by the rear locking hole, the first brush can be retracted into the barrel and the anti-drying unit closes the brush hole.

Abstract: A cap of a tube container having an automatic sealing structure, which more reliably performs an airtight function, prevents liquid ingredients in a nozzle from drying, safely protects the nozzle in a physical way, prevents gel-phased medical ingredients from being in contact with the outside air to the maximum extent possible, thus allowing the medical ingredients to be preserved for a longer period of time, and which is constructed so that the cap is integrated with the container, thus eliminating the risk of loss resulting from the separation. A cone which is secured by each locking protrusion inserted into a guide slit is inserted into a body as the locking protrusion moves, so that a nozzle hole is opened by an anti-drying unit and contents are discharged through an ejected nozzle.

Abstract: A rotary-type retractable writing implement with an anti-drying device is provided. An upper shaft and a lower shaft are coupled together such that the two shafts are rotatable in opposite directions, and a cartridge accommodated in an intermediate connection member is movable, and an open/shut module for covering a nib opens/shuts by the movement of the cartridge so as to provide a nib-advancing path.

Abstract: Disclosed herein is a one-touch-type gel container having an automatic sealing structure, which allows cosmetic ingredients to be preserved for a longer period of time, minimizes the volatilization of the cosmetic ingredients, and enables a desired amount of liquid ingredients to be used. As a screw lever is pushed, a locking protrusion of a cartridge moving along with the screw lever is removed from a second locking hole and is restrained by a first locking hole, so that a nozzle is ejected from a nozzle hole. As the area of the screw lever exposed to the outside of rotary lever holes of a barrel and the cartridge m reaches a maximum, the piston fastened to the screw lever in a threaded manner moves forwards when the screw lever is rotated, so that contents are pushed from the cartridge and are discharged through a contents moving part to the nozzle.

Abstract: Disclosed herein is a slide type writing tool having a dryness prevention unit. The writing tool includes a hollow shaft (10) having a nib hole, with shutter shaft seats protruding from the inner wall of the shaft. A cartridge (20) is secured to the shaft. A knock part is inserted into an insert hole formed in the shaft, and a pair of pressing parts is provided on a nib extension shaft of the cartridge. A rear O-ring (30) surrounds an end of the cartridge. A spherical shutter (40) is held in the rear O-ring (30), and has a spherical shutter part to isolate a nib from the exterior. A front O-ring (50) contacts the shutter part and the nib hole. A spring contacts at a first end thereof a lower end of a step of the cartridge, and at a second end thereof a step of the rear O-ring.

Abstract: The present invention relates to a rotary-type retractable writing implement with an anti-drying device, wherein an upper shaft and a lower shaft are coupled together such that the two shafts are rotatable in opposite directions, and a cartridge accommodated in a intermediate connection member is movable, and an open/shut module for covering a nib opens/shuts by means of the movement of the cartridge so as to provide a nib-advancing path.

Abstract: The present invention relates to a writing implement, both ends of which are retractable, in which an upper shaft and a lower shaft are coupled together such that the two shafts are rotatable relative to each other, and thus a cartridge and an eraser holder accommodated in an intermediate connection member are simultaneously movable in the upward and downward directions.

Abstract: A retractable writing instrument having a dryness prevention device is disclosed. The retractable writing instrument includes a casing (10), which has a nib hole therein, a cartridge (20), which has a nib coupling protrusion for coupling a nib (24) to a nib extension tube, and a spring for providing elastic restoring force. The writing instrument further includes an Oring member (50), which is coupled to the nib extension tube, and an openable ring (40), which is rotatably coupled to the Oring member (50). When a knock part is pushed, the openable ring (40) is rotated, such that a through passage is opened, and the nib is protruded outside through the nib hole. When the cartridge is moved backwards, the nib coupling protrusion of the cartridge holds the Oring member and is moved backwards along with the Oring member, thereby rotating the openable ring, thus closing the through passage.
