Abstract: A manually supported housing has a handle extending therefrom in the area of the top thereof. A storage area in the housing stores material and has an opening at the bottom of the housing. A manually controlled dispenser control device in the housing, and extending therefrom, manually selectively controls the dispensing of material from the storage area.

Abstract: A holder member for resting on a user's thigh comprises a plate-like thigh part bent at an obtuse angle for resting on a user's thigh and a plate-like support part extending from an edge of the thigh part at right angles therewith. A desk member for use by the user as a desk comprises a plate-like planar rest part and a plate-like mounting part extending from an edge of the rest part at right angles therewith. A fastening device adjustably movably affixes the desk member to the holder member for rotation of the mounting part of the desk member coplanar with the support part of the holder member about an axis perpendicular to the mounting part and support part and for movement of the rest part of the desk member relative to the thigh part of the holder member to vary the distance therebetween.

Abstract: A display device consists of a plate-like sheet of rigid transparent material having a pair of spaced opposite parallel edges. The sheet is bent in the area of each of the edges along lines parallel to and spaced from the edges to form a pair of lips. Each of the lips extends at a predetermined angle with the sheet in the area of a corresponding one of the edges. Each angle opens toward the other. Adhesive is provided on corresponding surfaces of the lips.
