A pen assembling press includes a base, a press unit, a carriage, and a positioning arrangement. Actuation of a lever moves an engagement head relative to the base along an actuation axis. A second engagement head is coaxial with the first engagement head. The carriage is movably mounted to the base. The positioning arrangement includes a slot, a plurality of recesses and a pin. The slot extends through the first leg in a direction perpendicular to the actuation axis. The slot has a constant height section having a height. The pin has a shaft and a head. The head is receivable in the recesses. The shaft has a thickness being substantially equal to the height of the constant height section of the slot. The pin is movable relative to the carriage along a pin axis that is perpendicular to the actuation axis to selectively engage and disengage the recesses.

Disclosed is a knock-type pen, which includes: a housing having a -shaped guide groove formed at a top end thereof; a pen seam accommodated in the housing; a pressing member having a moving protrusion provided at a lower end thereof and movably inserted into the guide groove; a rotating member rotatably coupled to an outer circumference of the top end of the housing and having a l-shaped slide groove into which an end of the moving protrusion inserted into the guide groove is movably inserted; and a knock unit disposed between the pressing member and the pen seam and configured to allow an end of the pen seam to move in and out at a lower end of the housing when the pressing member is pressed.

A writing instrument includes a barrel and a cap capable of being assembled with and secured to the barrel. The barrel carries a writing instrument. The cap carries a clip. A free end of the clip includes a detent that can be received by a corresponding indentation of an exterior surface of an external portion of the barrel when the cap is assembled with the barrel. The detent of the clip and the indentation of the barrel are capable of securing the cap and the barrel in their assembled relationship. The writing instrument may be compact. Methods of using a writing instrument include securing a cap of the writing instrument to a barrel of the writing instrument by causing a detent of a free end of a clip of the cap to engage a corresponding indentation of an exterior portion of the barrel.

A cap assembly (200) for a drug delivery device is presented. The cap assembly (200) comprises a fixing element (134) with a connection feature (154), an outer part (130) with an opening (164), and an inner part (131) being located inside of the outer part (130), the inner part (131) further comprising a corresponding connection feature (170), wherein a section of the fixing element (134) extends through the opening (164) of the outer part (130), such that the fixing element (134) is connected to the inner part (131) by an interaction of the connection feature (154) and the corresponding connection feature (170).

A pen for writing and/or drawing purposes, and having a shaft and a core which is arranged within the shaft and is axially adjustable in the longitudinal direction of the shaft between an active position and an inoperative position. The core is completely arranged within the shaft in the inoperative position and projects with an overhang from a front end of the shaft in the active position. An actuating element is provided which is movable perpendicularly to the longitudinal direction of the shaft between an active position and an inoperative position and which is operatively connected to the core via a connecting element in such a way that, during a movement of the actuating element perpendicularly to the longitudinal direction of the shaft between the inoperative position and the active position, the core is axially adjustable in the longitudinal direction of the shaft.

A banana shaped writing device; the banana shaped writing device includes a body, a lead, a stem, a peel, and a metal clip. The banana shaped writing device is useful for allowing a user to peel the writing device and provides a cushioned finger hold. Further, the banana shaped writing device is helpful to teach children who are beginning to write the proper finger positions to write.

Provided is a knock type writing instrument provided with a simple mechanism allowing a stable fretting operation or the like. A knock type writing instrument 1 is provided with: a shaft cylinder 2; a refill 5 arranged inside the shaft cylinder 2; a spring 6 biasing the refill 5 backward; an operation part 20 pressed forward against a biasing force of the spring 6 in a knocking operation; and a main rotor 30, and is switchable between a writing state and a non-writing state with the knocking operation. The knock type writing instrument 1 is further provided with: a knock locking member 50 movable forward and backward inside the shaft cylinder 2 due to gravity; and a locking part 60 provided on a side of the shaft cylinder 2 and capable of being locked with the knock locking member 50. When a front end of the shaft cylinder 2 is directed upward, the knock locking member 50 moves backward to be locked with the locking part 60 to prevent forward movement of the operation part 20.
