Multifunctional drinking cup structure

Abstract

The present invention discloses an improved multifunctional drinking cup structure, comprising a cup body, an inner cup lid, and an outer cup lid, wherein the inner cup lid is used to cover the opening of the cup body directly, the inner cup lid has an outlet hole, a convection hole, a primary insert hole, and a secondary insert hole (as needed), and the outer cup lid has a corresponding outlet hole, a convection hole, a main insert hole, and a secondary insert hole; the outer cup lid is covered inside the cup body, such that when the outer cup lid is rotated to align the corresponding holes, beverage can be drunk from the outlet hole by the mouth, or by sucking a straw that is inserted into the primary insert hole or the secondary insert hole. Both of the primary insert hole and the secondary insert hole have a guiding structure that prevents the straw from being askew. The outer cup lid may have no holes at all, but is simply used to cover the inner cup lid. The structure of this invention can be made of hard materials, comprising a cup body and a lid body, wherein the cup body similarly comprises an outlet hole and a convection hole, and an inner thread and an outer thread are disposed on the top end and the bottom end of the lid body respectively, such that the lid body can be secured on the top end or the bottom end of the cup body.
