A writing instrument comprising a housing extending in a longitudinal direction and having a radial direction, and first and second concentric writing tips, the second writing tip arranged around the first writing tip, each writing tip received in the housing and able to assume an operating configuration, the housing comprising, at a longitudinal end, a deformable nose at least in the radial direction, the deformable nose comprising at least one slit extending in the longitudinal direction, the deformable nose not being deformed when only the first writing tip is in an operating configuration and the deformable nose being deformed when the second writing tip is in an operating configuration, the deformable nose comprising an exit opening of the first and second writing tips, the diameter of the exit opening being greater than the diameter of the first writing tip and less than that of the second writing tip.

A mechanism of a daily commodity ejecting and retracting device includes an operating portion provided to rotate around a center line vertical to an axis line of a shaft tube in relation to the shaft tube between a first rotation position and a second rotation position. A rod portion is coupled within the shaft tube to rotate around a first axis line and is coupled to the daily commodity to rotate around a second axis line which is parallel to the first axis line. An eccentric position of the first axis line is set so that the daily commodity is immersed into the shaft tube via the rod portion when the operating portion is rotated to the first rotation position, and the daily commodity protrudes out of a leading end port of the shaft tube via the rod portion when the operating portion is rotated to the second rotation position.

A multifunction writing instrument comprising a body extending along an axial direction and housing at least two writing elements, each writing element comprising a writing tip, a selector device configured to select one writing element from among the at least two writing elements, a retraction device configured to move a selected writing element between a writing position in which the writing tip of the selected writing element projects from the body and a retracted position in which the writing tip of the selected writing element is retracted, and a return device configured to bring a writing element from the writing position to the retracted position when the selector device is activated while a writing element is in the writing position.

An application container includes a main body cylinder, an application tool, and an engagement portion. The main body cylinder has a first end and a second end opposite the first end. The application tool is insertable into the main body cylinder through the first end of the main body cylinder. The engagement portion is positioned within the main body cylinder, and includes a cylindrical portion to connect with the application tool and a connector that connects the cylindrical portion and the main body cylinder. The cylindrical portion of the engagement portion is spaced apart from the main body cylinder.

A housing element for a writing instrument includes a hollow, sleeve-shaped, elongated base body having an opening for receiving the writing instrument or a pencil lead of the writing instrument at a first longitudinal end. The base body has a second longitudinal end, which is opposite the first longitudinal end, and has a retaining recess that is formed with a polygonal cross section for directly or indirectly retaining a bit in a rotationally fixed manner. A writing instrument including the housing element is also provided.

Manual device (200), comprising a casing (212) having a first distal end (12-1) and a second distal end (12-2), a first head (16A) and a second head (16B) that are movable axially between a use position and a retracted position, and a single mechanism (214) that is configured to bring the first head (16A) and the second head (16B) from the retracted position to the use position and vice versa, the mechanism (214) comprising at least one carriage (214A1, 214A2) having at least one head selected from the first head and the second head (16A, 16B) and a single spring (214B).

A writing instrument comprising a housing extending in a longitudinal direction and having a radial direction, and first and second concentric writing tips, the second writing tip arranged around the first writing tip, each writing tip received in the housing and able to assume an operating configuration, the housing comprising, at a longitudinal end, a deformable nose at least in the radial direction, the deformable nose comprising at least one slit extending in the longitudinal direction, the deformable nose not being deformed when only the first writing tip is in an operating configuration and the deformable nose being deformed when the second writing tip is in an operating configuration, the deformable nose comprising an exit opening of the first and second writing tips, the diameter of the exit opening being greater than the diameter of the first writing tip and less than that of the second writing tip.
