| 20090028626 | Mechanical pencil - A mechanical pencil includes an advancing mechanism and a slider both incorporated in a main body. The advancing mechanism has a chuck and a chuck ring (collar for fastening the chuck) for holding a lead, so as to advance the lead. The slider is slidable relative to the main body and has a lead guide and a lead friction member. The lead friction member is to friction with the lead and is made of thermoplastic elastomer. | 01-29-2009 |
| 20090317167 | DELIVERY SYSTEM - The present invention generally is a delivery system for dispensing product(s) in adjustable quantities comprising a body, said body having at least one cavity for housing the product(s) and a plunger or a piston and rod assembly, an actuator being in communication with the cavity in the body, said actuator having an inclined profile at one of its ends which is in communication with the body, and a means for changing the position of the incline of the actuator with respect to the body wherein changing the position of the inclined profile of the actuator with respect to the body delivers different quantities of the product(s). | 12-24-2009 |

| 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 |
| 20110188918 | Mechanical pencil - A mechanical pencil has a hollow longitudinal main body and a slider slidably mounted in a front end of the main body. The slider has a through-hole through which a lead is fed and a front end face formed into a spherical surface centering around the through-hole for contacting a writing surface during a writing operation of the mechanical pencil. | 08-04-2011 |
| 20110229245 | SIDE KNOCK TYPE MECHANICAL PENCIL - A side knock type mechanical pencil includes a knock button, a barrel, an intermediate lead tube, and a clip. A fixed hole is formed in the side wall of the front end of the barrel, and a rib groove is formed in the inner front side of the fixed hole. At least one button groove is formed in the front end of the knock button, and at least one protrusion or bump with an inclined plane is formed at the lower side of the rear end of the side button. A shaft is formed by the engagement of the button groove of the front end of the button with the rib groove of the fixed hole. At least one circular bulge which is adapted to engage with the protrusion or bump with the inclined plane is disposed on the side of the intermediate lead tube. | 09-22-2011 |

| 20140079462 | MECHANICAL PENCIL HAVING LEAD-ROTATING MECHANISM - A mechanical pencil incrementally rotates a lead by operation of a touch button. The pencil has a barrel in which is disposed a holder. A rotatable pipe having a writing mechanism assembly incorporated therein is attached rotatably to the holder. Around the periphery of the holder, a slide member is disposed to undergo forward and rearward movement, and the slide member is moved forward by pressing the touch button disposed on the barrel. The holder houses a sleeve which is moved forward by the slide member and which turns in a circumferential direction. A rotation-transmitting cam face is provided on each of a front end face of the sleeve and a rear end face of the rotatable pipe. By the forward movement of the sleeve, the cam faces are engaged with each other to incrementally rotate the rotatable pipe, whereby the lead is incrementally rotated. | 03-20-2014 |
| 20150023714 | MECHANICAL PENCIL - A mechanical pencil is provided which does not require operation of removing or re-fitting a cap but allows writing immediately after supplying a writing lead. A lead fixing chuck | 01-22-2015 |
| 20150030369 | MECHANICAL PENCIL HAVING LEAD-ROTATING MECHANISM - A mechanical pencil has a main body inserted into a tubular main body cover to undergo forward and rearward movement and rotational movement within the main body cover. The main body feeds a lead and holds the lead during writing. A gear mechanism incrementally rotates the main body based on the presence or absence of writing pressure occurring during writing to thereby incrementally rotate the lead. Protection collars are rotatably mounted on the outer periphery of the main body at locations where the main body is exposed from the main body cover. The protection collars rotatably idle on the main body to prevent a person from gripping and rotating the main body thereby preventing damage to the gear mechanism. | 01-29-2015 |

| 20110020048 | CLICKING TYPE DISPENSING CONTAINER - A clicking type dispensing container that can dispense the content by pressing a crown disposed at the rear end of a barrel body, forwards in the axial direction, and has a structure, including a mechanical assembly that transforms the pressing force acting on crown by user operation into rotational force, a threaded body fixed to barrel body and a threaded rod screw-fitted into threaded body, and dispensing the content by advancing the threaded rod through the threaded body when the threaded rod is turned by the rotational force transformed by the mechanical assembly. The clicking type dispensing container can produce the rotational force without depending on spring force and cam configuration only, is constructed of a fewer number of parts and can dispense a fixed amount of the content by use of a thread. | 01-27-2011 |
