Abstract: A mask has a main body and at least one attaching member. The main body is a flexible material and has at least one folded section at a middle portion. Two short edges of the main body are formed by a hot melt press process to provide two sealed edges for securing the folded sections and the attaching member. The two sealed edges have at least one horizontal, cut-open gap. The cut-open gap allows the two sealed edges to form at least one overlapped portion and the two sealed edges are respectively curved as an arced edge. The overlapped portions increase the sealing effect of the two sealed edges, which greatly improves the covering effect of the main body, and indeed prevents bacteria and viruses in the air from invading from both sides of the main body to help improve the safety and the protection effect of the main body.

Abstract: A cup lid may comprise a main body having a cup edge at an outer periphery thereof. An upper surface of the main body has a cover comprising a concave upper surface, and a first end and a second end are respectively formed at two opposed edges of the concave upper surface at corresponding positions. A concave sip portion formed adjacent to the first end, and a plane surface is formed at a bottom portion of the sip portion. A flippable sealing member extends from the plane surface, and a sip-through opening is formed overlapped with the sealing member. A month-contact portion is formed adjacent to the first end, and a height difference formed between the month-contact portion and the sip-through opening is configured to prevent the overflow of beverage when drinking.

Abstract: A lunch box includes a main body having a bottom portion, two side portions, a front portion and a back portion to define a receiving space, and a cover that covers upper portion of the main body extending from the back portion. Two side portions extend from bottom part of the junction of the front portion and back portion to form first shaping lines, and a retracting portion is formed between two side portions and two first shaping lines, and an expanding portion is formed at the junction of first shaping lines and the front portion. When the cover is bended down to cover the main body, the front portion is restored when the retracting portion rebounds, and the expanding portion is outwardly against the junction of the front cover and side covers to form a restricting position, so the box can be closed securely without external securing components.

Abstract: A heat-insulating cup includes a cup, a ring, and a sleeve. The cup includes an open end, a closed end, and a body between the open end and the closed end. The open end has an edge bent outward to form a flange. The ring is securely mounted around an outer periphery of the body and has two open ends. The sleeve is mounted around the ring and includes upper and lower open ends. The upper open end of the sleeve abuts a bottom of the flange of the body. A heat-insulating space is provided between the sleeve and the body to effectively avoid a hand of a user from high heat.

Abstract: An instant teabag includes a cup and a teabag. The cup includes an open end and a closed end. The teabag includes a sealed perimeter and receives a content. The sealed perimeter is fixed to an inner face of the closed end at at least one point. A cotton yarn includes an end fixed to the sealed perimeter at another point opposite to the at least one point. A piece of paper is fixed to the other end of the cotton yarn. The tealeaves or powder in the teabag can expand or spread when water is poured into the cup. Furthermore, a user can move the yarn and hence the teabag with a slight force to expand or spread the tealeaves or tea powders in the teabag. The teabag can be pulled off the closed end of the cup.
