| 20110191987 | CLIP ATTACHMENT STRUCTURE FOR A WRITING INSTRUMENT - A clip mounting structure for a writing implement has a shaft tube, a clip mounted at the rear part of the shaft tube, and an insertion member inserted into the rear part of the shaft tube. A clip mounting section to which the rear part of the clip is fitted and aligned is formed at the rear part of the shaft tube. Mounting sections curved in the direction along the inner peripheral surface of the shaft tube are formed at opposite sides of the rear part of the clip. Fitting recesses into which the mounting sections of the clip are fitted are formed in the outer wall of the insertion member. With the mounting sections of the clip fitted in and engaged with the fitting recesses in the insertion member, the insertion member is inserted into the rear part of the shaft body to fit the rear part of the clip into the clip mounting section of the shaft tube. Thus, the insertion member is engaged in position inside the shaft tube. | 08-11-2011 |
| 20110123250 | KNOCK-TYPE WRITING INSTRUMENT - A knock-type writing instrument is provided, which allows an easy refill exchange with a simple operation while inhibiting deformation of slits, breakage of a shaft tube, etc., during the refill exchange. | 05-26-2011 |
| 20100021227 | STICK-SHAPED ARTICLE PROPELLING CONTAINER - Variations in the size of a stick-like object are accommodated, and abutments are urged to contact with the stick-like object with an appropriate pressure. | 01-28-2010 |
| 20100003063 | Liquid Applicator - There is provided a liquid applicator allowing a liquid to be easily replenished and replaced, as well as capable of containing a large amount of liquid. The liquid applicator includes a main body provided with a tank inside thereof, a tip shaft that is coupled to the tip end side of the main body, and a brush that is fixed in the tip shaft and projecting from the tip end of the tip shaft. A liquid may be sucked into a tank by releasing the coupling of the main body and the tip shaft, sinking a tip end opening of the main body in the liquid, and sliding a sliding cylinder attached to the rear portion of the main body. | 01-07-2010 |
| 20080260453 | End plug mounting structure for writing instrument - An end plug mounting structure for writing instrument of the present invention can securely mount an end plug onto a barrel and remove it more easily. Even if assembling and removing is performed repeatedly, tightness for the end plug to be assembled on the barrel can be prevented from weakening. A locking hole is provided around cylindrical rear portion of the barrel, an inserting portion with circular cross section inserted into rear portion of the barrel from rear end of the barrel is provided on the end plug, a locking protrusion locked in a locking hole is provided at periphery of the inserting portion, a groove extending forward from rear end of the barrel and in which the locking protrusion moves is provided on inner surface of rear portion of the barrel, thereby the end plug is assembled on the barrel by means of locking the locking protrusion that moves forward in the groove in the locking hole. The locking hole is configured to be adjacent to the groove, so that the locking protrusion moving forward in the groove moves in circumferential direction so as to be locked in the locking hole. A protruding strip extending in lengthwise direction is configured on side bottom of the groove on the side of the locking hole, so that the locking protrusion can stride over the protruding strip to move along circumferential direction. | 10-23-2008 |
| 20080247804 | Stick-Shaped Material Propelling Container - In a stick-shaped material propelling container capable of propelling and retracting a stick-shaped material, the influence of variation of the dimension of the stick-shaped material can be made small. An inner barrel is slidably inserted in an outer barrel, an elastic body which urges the inner barrel rearward is provided between the inner barrel and the outer barrel, a chuck piece which holds a stick-shaped material is provided at a tip end portion of the inner barrel, and a chuck ring is inserted between the chuck piece and the outer barrel. A cross section of the stick-shaped material forms a triangular shape, the frictional force applying part which is in contact with the stick-shaped material to apply a frictional force is formed on an inner peripheral surface of the outer barrel, and the frictional force applying part abuts on a side in the vicinity of a vertex of the stick-shaped material in a cross section of the stick-shaped material. | 10-09-2008 |
