676 results about "Petal" patented technology

Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. Together, all of the petals of a flower are called a corolla. Petals are usually accompanied by another set of special leaves called sepals, that collectively form the calyx and lie just beneath the corolla. The calyx and the corolla together make up the perianth. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term tepal is appropriate include genera such as Aloe and Tulipa. Conversely, genera such as Rosa and Phaseolus have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly coloured tepals. Since they include Liliales, an alternative name is lilioid monocots.

Toy water ball

A toy wall ball includes a pair of petals and a connecting portion connecting the petals. Each petal includes a body, a frame extending inward from the body and a magnetic attraction assembly embedded between the body and the frame. Each magnetic attraction assembly includes magnetic members and a fixing member including fixing cases and connecting strips. Each fixing case encloses a corresponding magnetic member and is connected to a connecting strip. When the petals are in a closed state, the petals jointly enclose and define a water-carrying cavity, and the magnetic members of the petals attract each other to have the frames of the petals tightly contact each other to form a water retaining layer that seals the water-carrying cavity. The connection area between the magnetic members and the frame and body is increased, thereby greatly reducing the risk of the magnetic members falling off the petals and improving safety.
