Abstract: A protection case includes a receiving portion for receiving an electronic device and a cover portion connected to one side of the receiving portion for supporting or covering the receiving portion. The cover portion includes a first reinforcing member, a second reinforcing member adjacent to the first reinforcing member, two third reinforcing members symmetrically located at two opposite sides of the first reinforcing member, and two fourth reinforcing members symmetrically located at two opposite ends of the cover portion. The first, second, third and fourth reinforcing members are connected flexibly to each other. The first reinforcing member is folded toward and absorbed on the second reinforcing member. Each of the two third reinforcing members together with the adjacent fourth reinforcing member forms a supporting portion to abut against the back of the receiving portion.

Abstract: A protective cover for protecting and supporting a portable electronic device includes a bottom cover and a top cover including three segments. One of the segments at a first side of the top cover is pivotably attached to the bottom cover. Another one of the segments at a second side of the top cover is magnetically attracted to a back of the bottom cover. The segment at the second side of the top cover is slidable along the back of the bottom cover to adjust an angle of the bottom cover relative to a platform.

Abstract: A plastic product having patterns in three dimensions includes an injecting base and a first film adhered to one side of the base. The first film includes a first pattern away from the base and a thickening layer attached to the first pattern. The first pattern is positioned between the thickening layer and the first film. A first raised portion is formed on the first film and inserted into the base.

Abstract: A method for protecting a hole includes putting an end of a handle in the hole, then filling the hole with material. The material is then cured to form a plug which protects the hole and can be pulled out to open the hole by the handle when needed.
