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 holder for a pencil eraser with removable bands. As the eraser wears, connecting bands are removed, revealing more of the eraser. As the connecting bands are removed, they are replaced at the rear end so that the length remains the same. When the eraser is completely worn out, a new eraser is inserted in the eraser case.

The present invention provides devices, systems, and methods for refilling a refillable fluid applicator, such as but not limited to a refillable dry erase marker. The devices, systems, and methods of the present invention advantageously allow the fluid applicator to be refilled quickly, easily, and inexpensively, and provide the benefit of significantly reducing the quantity of solid plastic waste associated with conventional disposable dry erase markers and other fluid applicators.

An eraser assembly is provided that includes a housing, a tray, a coupler, and an eraser insert. The housing has a concave shape including an interior portion. The tray has a retaining portion disposed in the interior portion of the housing and a mounting portion disposed opposite the retaining portion. The coupler is configured to releasably hold the tray to the housing. The eraser insert is configured to be mounted to the mounting portion. An eraser insert is also provided that includes a first side and a second side, an eraser pad, and a coupler. The first side includes a mounting surface and an eraser pad is disposed on the second side. The coupler is disposed on or about the mounting surface and is configured to detachably connect the eraser insert to an eraser assembly at the mounting surface.

A self-righting handheld utensil comprises a weighted base having a generally rounded bottom end, an elongated region extending outwardly from the base, and a use portion. The base, by virtue of its generally rounded bottom and mass, provide for a self-righting function for the disclosed utensil such that, when placed on a flat or substantially flat surface, it counterbalances the utensil to an upright vertical orientation without the need for user intervention or the application of any external force. The base need not become uncoupled from the elongated region and use portion before the user makes operative use of the disclosed utensil. The bottom end of the base may comprise one of several structural embodiments that retain the self-righting function of the utensil.

An eraser case includes a cylindrical container in which an eraser with a cylindrical hole is stored to be extendable and retractable. A twist-up base is slidable in an axial direction inside the cylindrical container, and an end part of an eraser stored in the cylindrical container is fixed to the twist-up base. A screw shaft body can be inserted into the cylindrical hole of the eraser and can push the twist-up base out by being inserted into and threadedly engaged with a screw hole piercing through the twist-up base to convert an axial rotational motion into an axial motion of the twist-up base. The twist-up base includes a convex locking portion protruding toward the eraser. The convex locking portion fixes the eraser to the twist-up base by being locked to a concave locking portion provided on an inner wall surface of the cylindrical hole of the eraser.

A soft-member attachment structure includes an attachment hole provided through a rear end portion of a barrel. The barrel configures a thermochromic writing instrument, along a longitudinal central axis and having an inner circumferential surface between two openings located at an upper end and a lower end; an attachment portion located under a large diameter portion of a soft member used for a thermochromic change and having a diameter being smaller than a diameter of the large diameter portion and allowing insertion into the attachment hole; a straight internal hole provided along a longitudinal central axis of the soft member and opening at least at a lower end of the soft member; and a rod-like inner core having an outer diameter allowing insertion into the internal hole, a length to be placed within the internal hole, and an outer circumferential surface contacting an inner circumferential surface of the internal hole.

A coating film transfer tool may include a supply reel, a transfer tape, a transfer head, a winding reel, and a power transmitting mechanism. The tool may include a base member having the transfer head and a rotation restraining portion capable of directly restraining rotation of the supply reel. The base member may be rotatably supported between the transfer head and the rotation restraining portion by a base member supporting shaft. The tool may include a resilient restoring mechanism interposed between the base member and the housing. The base member may rotate and restraint of rotation of the supply reel is released when the transfer head is pressed against a transferred surface, and the base member is restored to an original position by the resilient restoring mechanism to restrain rotation of the supply reel when pressing of the transfer head is released.

A manual device extends in an axial direction and includes a housing having a first housing portion and a second housing portion. First and second heads are each axially movable between a use position and a stowed position. The first head is in the stowed position when the second head is in the use position, whereas the second head is in the stowed position when the first head is in the use position. The first head and the second head both are carried by a single carriage movable in the axial direction and arranged inside a barrel. A groove forming a cam track is formed by a first shoulder of the first housing portion and by a second shoulder of the barrel. A lug of the carriage cooperates with the groove.

A whiteboard eraser includes a first side defining a grip surface, and a second side defining an eraser surface. The eraser surface comprises a reticulated scrubbing portion. The eraser surface may also include a textile wiping portion less abrasive than the reticulated scrubbing portion.
