Abstract: A rotating type cup lid, includes a cover having a cover portion with a first through hole formed therein, a wall surface disposed around the cover portion, and a flange connecting surface extended from the bottom edge of the wall surface. The rotating type cup lid further includes a rotating body corresponding to the cover portion of the cover. A protruding knob passes through a central circular hole and a downwardly tapered edge is formed at the periphery of the rotating body that is embeddable into an internal surface of the a first latch portion of the cover. The rotating surface of the rotating body includes a second through hole corresponding to the position of the first through hole, a punchable hole with X-shaped break lines, a small opening corresponding to a smaller straw, and a closed surface having no hole, each of which may be rotated into alignment with the first through hole.

Abstract: The present invention discloses a heat-resisting disposable drinking cup comprising: a cup body made by a plastic injection molding and having a cup opening disposed at the top of the cup body and folded outward to form a cup lip; several tens of radial ribs integrally formed at the bottom of the cup lip of the cup opening, and the radial rib is extended more than 1.5 mm from the surface of the cup body but remained within the external periphery of the cup lip of the cup opening, and the interval between two adjacent radial ribs falls within a range of 3˜5 mm, and the height of each radial rib is less than 10 mm measured downward from the cup lip of the cup opening; such that radiating fins can be formed around the external periphery of the cup opening.

Abstract: A rotating type cup lid, mounted on a cup opening of a cup body, for selectively turning open and close the cup opening or providing a use with a large straw or a small straw. The rotating type cup lid includes a cover having a cover portion, a wall surface disposed around of the cover portion, and a flange connecting surface extended from the bottom edge of the wall surface. The center of the cover portion has a protruded first circular groove while an internal side of the first circular groove has a central circular hole and an external side of the first circular groove with a first through hole. The middle section of the wall surface has an inwardly concaved first latch portion. Meanwhile, the rotating type cup lid includes a rotating body disposed corresponding to a cover portion of the cover and having a second circular groove with a rotating surface corresponding to the rotating surface of the first circular groove.

Abstract: A wireless communication system utilizes a protocol for creating a multi-to-multi point, extendable, ad-hoc wireless network. A hardware platform enables an electronic device to connect in an ad-hoc network. Accordingly, each electronic device with such a hardware platform of a plurality of such electronic devices functions as node in a network. The nodes function according to the protocol for form ad-hoc networks and to communicate data therebetween.
