Abstract: A transmission device for suppressing the glass-fiber effect includes a circuit board and a transmission line. The circuit board includes a plurality of glass fibers, so as to define a fiber pitch. The transmission line is disposed on the circuit board. The transmission line includes a plurality of non-parallel segments. Each of the non-parallel segments of the transmission line has an offset distance with respect to a reference line. The offset distance is longer than or equal to a half of the fiber pitch.

Abstract: A cup including a main body is provided. The main body has a bottom, an outer side surface and an inner side surface. The outer side surface is smooth and arcuate. The inner side surface has plural protruding portions extending longitudinally and arranged on the inner side surface annularly. The inner side surface has plural concave portions extending longitudinally. Each of the concave portions is formed between two protruding portions. The inner side surface is arranged with at least one reinforcing rib integrally protruding thereon and extending radially. The reinforcing rib divides at least parts of the protruding and concave portions into two material-reduced areas. Whereby, the usage of material of the main body can be reduced, and the reinforcing rib provides excellent structural strength of the main body.

Abstract: The present invention provides a mold for cup lids including a male mold and a female mold, wherein the male mold has a convex member, an annular member, and a first air channel. The annular member is annularly disposed at outside of a periphery of the convex member, and a gap is formed between the convex member and the annular member. The first channel communicates the gap and an external space. When mold closing, a mold cavity is formed between the male and the female molds, and a second air channel communicating the mold cavity and the external space is also formed therebetween. The gap communicates with the mold cavity. Thereby, the mold of the present invention can be injected with plastic material, and original air inside can be discharged from the air channels. Hence, the yield rate of injection is improved.

Abstract: The present invention provides a paper container and a method of making the same. The method comprises the steps of preparing a mold; sending paper into the mold; injecting plastic material after closing the mold; and opening the mold to acquire a paper container. Thereby, the plastic material can be connected between two distal ends of the paper. So the connection part of the paper is smooth and flat without any bumps, and the paper container has a good waterproof structure.

Abstract: The cap of the present invention has a cap surface and an engaging portion. The engaging portion includes an annular inner wall, an annular outer wall and an upper section connecting between the inner wall and the outer wall. The outer wall includes a first section and a second section. The first section is downward extended from the upper section, and the first section has a distal end, from which the second section is extended outward and downward. At least one engaging rim is formed between the first and second sections inward. An annular engaging slot is defined between the inner wall, the first section and the upper section for the engaging lip to engage therewith. A distance between the engaging rim and the inner wall is smaller than the thickness of the engaging lip so as to prevent the engaging lip from disengaging from the engaging slot.

Abstract: The cap of the present invention is adapted to cap a cup. The cap is formed with an opening, which has a first side and a second side. A pressing plate is extended from the first side toward the second side, and the pressing plate is swayable about the first side. The pressing plate has a distal end, from which a cutting rim is extended downward. The cutting rim is adapted to cut a film when the cap is in use and when the pressing plate is pressed downward. Thereby, the user can easily drink the contents in the cup via the opening.
