Abstract: A heating apparatus is used for heating liquid in a receiving body. The heating apparatus includes a cover body and a heating part. The cover body is for covering an opening of the receiving body. One end of the heating part is located at the cover body and extends downwards from the bottom of the cover body. Therein, one end of the heating part that is on the cover body is electrically connected with a power line. The power line is electrically connected with a source of electric power. Thereby, the inner wall of the receiving body can be easily cleaned. Additionally, a heating apparatus set is also disclosed.

Abstract: An optical disc can structure for deterring theft includes a lower cover and an upper cover. The center of the lower cover has a positioning column. The edge of the lower cover extends outward to form a circular protruding edge. On the protruding edge there are wedging parts. Under the wedging parts there are wedging slots. On the wedging parts there are fixing pins. The lower end of the fixing pin plugs into the wedging slot. A receiving space is formed in the inner part of the upper cover. On the bottom of the external wall of the upper cover there are a plurality of wedging bodies. The wedging bodies have fixing holes. The upper cover covers the lower cover. The wedging bodies can be rotated and wedged into corresponding wedging slots and the lower ends of the fixing pins are located in the corresponding holes.

Abstract: A burn-proof cup includes a cup body and two tabs. The cup body has a holding space inside for holding a liquid such as beverage or soup, etc. The two tabs connect with an upper circumference of the cup body and opposite to each other. The two tabs are bent to lean against the outer surface of the cup body by the lid. The tabs add a value of burn-proof effect to the cup so that the user can safely and conveniently carry the hot liquid around without worrying about being burn the hot liquid.

Abstract: A cup having a burn-preventing apparatus includes a cup body and two holding flakes. The cup body has a holding space formed in the inner space of the cup body for holding a liquid, such as a drink or soup, etc. The two flakes connect with the upper circumference of the cup body and are located on opposite sides. The two flakes are bent to lean against the outer surface of the cup body to form a burn-preventing apparatus. Thereby, the cup having a burn-preventing apparatus can be held by the user hand conveniently and prevents the user's hand from being burned.

Abstract: The present invention describes an optical disc cake box. The optical disc cake box has a stencil layer and a cone-shaped body. The cone-shaped body is integrally formed with the stencil layer by the injection molding process so that the optical disc cake box has a better decoration, artistry and advertisement. Efficiency of manufacturing the optical disc cake box is improved to meet mass production requirements.

Abstract: An optical disk storage case, which is formed integrally in a single body, has an upper case, a lower case, and at least three fasteners. The upper case and the lower case are connected side-by-side via a flexible connecting part. The upper case has a plurality of retaining pieces. The lower case has a plurality of hollow positioning plugs placed in a manner so as to be correspondingly received by the retaining pieces for firmly retaining the positioning plugs. The fasteners are spaced and correspondingly arranged on the first and second edges parallel to the connecting part. An increased amount of optical disks is therefore safely placed in the optical disk storage case.
