Abstract: A lid structure is arranged for detachably coupled at a container body to enclose a container cavity thereof, wherein the lid structure includes a container lid and a protective component. The container lid has a drinking hole and an expansion membrane for creating a negative pressure within the container body when the container lid is sealed at the container body. The protective member has a fixed end extended from the container lid and a sealed end detachably engaged with the drinking hole to seal the drinking hole for prevent liquid spilling from the container cavity.

Abstract: A fluid filter, which is adapted for separating a less dense fluid floating on a high dense fluid, includes at least a fluid filtering arrangement including a floating wing adapted for floating on the less dense fluid and at least a fluid outlet formed on the floating wing, and a container body, which is extended from the floating wing, having a fluid collecting cavity communicating with the fluid outlet, wherein the fluid outlet is formed at a position above the fluid collecting cavity. Therefore, when a downward force is applied on the floating wing until the fluid outlet is slightly positioned below a surface level of the less dense fluid, the less dense fluid is allowed to flow into the fluid collecting cavity through the fluid outlet by gravity.

Abstract: A beverage container includes an easy cleaning upper panel which has a flat opening portion and a lifting portion, wherein the flat opening portion can prevent the dirt from accumulating in the ring shaped indented groove formed around the upper panel of the conventional beverage container. Besides, an enlarged gap is sufficiently provided between a lifting portion on the upper panel and the lifting ring, so that the consumer can easily grip on the lifting ring. Moreover, a protective film is detachably attached on the upper panel so that the consumer may simply remove the protective film to obtain a clean panel surface for consuming the beverage.
