The corresponding thread fastener is located at the main body and is for joining with the thread portion. The elastic unit fastener is provided at the main body. The cap includes a cap case and an elastic unit corresponding fastener provided at the cap case. The two ends of the elastic unit are respectively fastened to the elastic unit fastener and the elastic unit corresponding fastener.

A writing, drawing, marking and/or cosmetic device, wherein the device includes at least one shaft and at least one inner body, wherein the at least one shaft is formed from concrete-containing material. The shaft at least partially surrounds the inner body. In the installation position the shaft is secured in an axial direction against axial displacement by a closing cover and a front part and a prestress is formed in the shaft in the axial direction via the closing cover and the front part.

A pen structure containing liquid ink is disclosed herein. It comprises a tube body having a reservoir and an open end; a liquid outflow bushing disposed at the open end and accommodated in the reservoir of the tube body at one end thereof, wherein the liquid outflow bushing has a liquid delivering space and a screw groove disposed on a wall of the liquid delivering space and connected to an end face of the liquid delivering space at one end thereof; and a brush disposed in the liquid delivering space of the liquid outflow bushing and surrounded by the screw groove at one end thereof.

Examples are disclosed that relate to textile coverings for electronic devices and methods for manufacturing textile coverings for electronic devices. In one example, a textile covering for an electronic device comprises one or more structural fibers woven into a seamless tube, the seamless tube configured to encircle at least a portion of the electronic device. The textile covering also comprises one or more heat-shrink fibers and/or one or more adhesive fibers woven into the seamless tube. The heat-shrink fibers shrink when the seamless tube is heated above a threshold temperature, thereby constricting the seamless tube around the electronic device. The one or more adhesive fibers adhere the textile covering to the electronic device.

A highlighter with a see-through area comprising a housing having a hollow body and an opening, an ink reservoir disposed inside the housing for storing ink, a nib disposed at the opening and an ink feeder disposed inside the housing for transporting ink from the ink reservoir to the nib. The housing further comprises a cut-out section disposed behind the nib to provide the see-through area for a user. The see-through area allows the user to see a section of text before highlighting. Alternatively, a section of the housing behind the nib can be constructed using transparent material such as plastic to provide a see-through area for a user.

Writing instruments are provided. A writing instrument includes a body, a nosecone, and an adaptor each being of generally hollow tubular shape. Each the body, the nosecone, and the adaptor each have a first end and a second end. The first end of the adaptor is configured to slidably couple to the nosecone second end. The second end of the adaptor is coupled to the first end of the body. The writing instrument includes a writing element with a mounting end and a writing end where the mounting end is removably coupled to the second end of the body. The writing instrument includes a locking mechanism configured to selectively lock the nosecone in a storage position or a writing position. In the storage position, the nosecone extends and covers the writing end. In the writing position, the nosecone retracts and the writing end of the writing element extends beyond the nosecone.

Writing instruments are provided. The writing instrument includes a body, a nosecone, and an adapter. The body, nosecone, and adapter each include a generally hollow tubular shape and an inner surface, outer surface, first end, and second end. The first end of the adapter is coupled to the second end of the nosecone. The second end of the adapter is configured to slidably couple to the first end of the body. The writing instrument includes a writing element with a mounting end and a writing end. The mounting end of the writing element is removably coupled to the second end of the body. The adapter includes a track and the track includes a recessed channel in the outer surface of the adapter. The body includes at least one protrusion that extends inward from the inner surface of the body. The protrusion slidably engages with the track of the adapter.

An input touch pen includes a digitizer refill contained inside a shaft tube and including a contact tip and a stepped tip portion rearward thereof, and a knock member protruding from an opening at a rear end of the shaft tube. The contact tip can protrude and retract through an opening at a tip end of the shaft tube. The stepped tip portion has a larger diameter than the opening at the tip end. A relationship A>X>Y is satisfied, wherein X represents a knock stroke of the digitizer refill, A a distance from the stepped tip portion to an inner surface at the tip end side when the contact tip is sunken inside the opening, and Y a distance that the contact tip is moved by operation of the knock member from a state of protruding from the opening to a state of being sunken inside the opening.

A writing instrument may include an upper barrel rotatably connected to a lower barrel. Writing fluid reservoirs may be housed in the upper barrel. A writing tip secured to the lower barrel may be in selective fluid communication with the writing fluid reservoirs. The upper barrel may be rotatable relative to the lower barrel of the writing instrument.

The present invention provides a writing implement, including a pen tube, a guiding element, a motion sensor, and a controller. An end portion of the pen tube is provided with a nib. The guiding element and the motion sensor are disposed on the pen tube, and the guiding element is controlled by the controller. In the process of writing, the motion sensor detects words and pencraft characteristics when a user holds the pen tube for writing, and the controller controls the guiding element to generate a guiding force to guide the words and pencraft characteristics when writing, to approach or be equal to words and pencraft characteristics prepared to be written. Therefore, the present invention may train a user to copy the handwriting of a master or actively guide the user to wield the pen by means of the writing implement.
