Abstract
A cup system including a lid, a liner, an outer cup, and an optional valve. The liner includes first and second mating surfaces. The liner first mating surface is selectively attachable to a corresponding mating surface associated with the outer cup and the liner second mating surface is selectively attachable to a corresponding mating surface associated with the lid. The mating surface of the lid is also selectively attachable to the mating surface of the outer cup such that present cup can be utilized as either an insulated or a non-insulated cup. The optional valve assembles to the lid by pressing the boss of the valve into a valve receiver associated with the lid.
Claims14
A cup system comprising:
- an outer cup with an interior and a mating surface;
- a liner with first and second mating surfaces, wherein the first mating surface of the liner is configured to selectively mate with the mating surface of the outer cup;
- and
- a lid with a mating surface, wherein the mating surface of the lid is configured to selectively mate with the second mating surface of the liner and the mating surface of the outer cup.
A cup system comprising:
- an outer cup with a mating surface at an upper end thereof;
- a liner with a first mating surface at an upper end thereof and a second mating surface below the first mating surface, wherein the outer cup mating surface is selectively attachable to the second mating surface of the liner, and wherein selectively mating the liner with the outer cup forms a space between the liner and the outer cup;
- and
- a lid with a mating surface at a lower end thereof, wherein the mating surface of the lid is selectively attachable to the first mating surface of the liner.
A method for creating a cup comprising the steps of:
- providing an outer cup having a mating surface;
- configuring a liner to fit within the outer cup such that a space exists between the liner and the outer cup;
- configuring said liner to have first and second mating surfaces, the first mating surface thereof being configured to selectively mate with the mating surface of the outer cup when said liner is placed within said outer cup, where said selective mating forms an air-tight seal to contain any substance residing in the space between the liner and the outer cup;
- and
- providing a lid having a mating surface which may be selectively mated to the outer cup mating surface or the second mating surface of the liner.
