A washing machine outlet box cover that has an outlet box association structure such as channels or a latch and hook system, reversibly covers and uncovers a washing machine outlet box. The washing machine outlet box cover protects the washing machine outlet box and the structures contained therein, and it may be used to hide those structures from view during normal operation.

A removable lid for a drinking cup is described. The removable lid has a top side with an ellipsoidal recession having a bottom opening. A baffle wall extends from the perimeter of the bottom opening, and is configured to prevent a beverage from passing through the bottom opening upon sudden movement of the beverage. The ellipsoidal recession may be designed so that a hot beverage being consumed through the removable lid is exposed to more outside air for cooling purposes. The same ellipsoidal recession may be designed to funnel added ingredients into a beverage. The removable lid may have a stirrer opening so that stirrers may be inserted and taken out without lid removal. For additional strength, the surface of the removable lid may be textured to increase its moment of inertia. The bottom opening of the removable lid may be closed using a fitted blocking plug.

A replacement lead case includes a case body that forms an inner space surrounded by a rear surface plate and right and left leg plates as a replacement lead accommodation room and has a lid body on the tip end thereof and a case part on a rear part thereof via a bendable thin part provided on the rear surface plate, and a cover member that has a U-shaped cross-section orthogonal to a longitudinal direction molded by a front surface plate and right and left outer leg plates covers the replacement lead accommodation room on a case body with the front surface plate and slidably supports the case body in the longitudinal direction with the leg plates positioned on the inside of the outer leg plates. A rail-shaped guide is formed on the lid body along the longitudinal direction, and the cover member includes a slider that contacts the guide.
