Embodiment Construction
[0021]Referring to FIG. 4 for a perspective view of a preferred embodiment of the present invention, the invention comprises: a cup body 30 formed by a plastic injection molding process and made of a polypropylene (PP) material or a polyethylene (PE) material. The cup body 30 has a cup opening disposed at the top of the cup body 30 and folded outward to form a cup lip 31 around the cup opening, and these elements constitute the structure of a general plastic cup.
[0022]The present invention is characterized in that several tens of radial ribs 40 are integrally formed at the bottom of the cup lip 31 of the cup opening as shown in FIGS. 5 and 5A, and the radial ribs 40 are extended at least 1.5 mm from the surface of the cup body 30, and an interval D between two adjacent radial ribs 40 falls within a range of 3˜5 mm. The results of experiments show that the interval D can prevent a user's palm or finger from touching an external surface 33 of the cup body 30 while the user is holding ...
