An edible cap for selectively covering an open end of a cup includes an edible flat body, an edible wax layer and an edible film. The edible flat body is in the form of a cap. The edible flat body is a solid body including a top portion and a wall extending around the top portion in a circle of a certain diameter to provide a profile in compliance with the open end of the cup. The wall includes an opening for receiving the open end of the cup. The edible wax layer is attached to a face of the edible flat body. The edible film is attached to a face of the edible wax layer opposite to the flat body in a detachable manner.

An adhesive tape with high high-load holding power, initial adhesive strength, and repeelability is provided. An adhesive layer of the adhesive tape contains filler particles and a triblock copolymer with a repeating unit represented by the following general formula (1):

##STR00001##

A, B, and C independently denote a repeating unit. A and C independently denote an alkyl methacrylate monomer unit and B denotes an alkyl acrylate monomer unit. p, q, and r independently denote the degree of polymerization of their monomer units respectively. A and C may be the same or may denote an alkyl methacrylate monomer unit with a different chemical structure, and * denotes a bonding arm to another atom. A relationship D50/T between an average particle size D50 of the filler particles and an average thickness T of the adhesive layer ranges from 0.05 to 1.0.
