Stainless steel lid portion of a fluid dispenser system

A stainless steel lid portion of a fluid dispenser system useful for storing and delivering fluid, the stainless steel lid portion comprising:

• an annular side wall forming a first circular opening having a first diameter, the annular side wall comprising a female thread adjacent the first circular opening, the female thread configured to engage a male thread of a stainless steel container portion of the fluid dispenser system to couple the stainless steel lid portion to the stainless steel container portion, the stainless steel container portion defining an inner chamber and having a first end and a second end, the first end is closed and forms a base of the inner chamber, the second end having an opening and a cylindrical neck portion, the cylindrical neck portion comprising a top rim adjacent the opening of the stainless steel container portion, the cylindrical neck portion comprising the male thread, the male thread having a major diameter larger than a diameter of the opening of the stainless steel container portion;
• and
• a lip portion comprising a top layer and a bottom layer, the top layer extending inwardly from a top portion of the annular side wall to an inner edge, the top layer being entirely straight between the annular side wall and the inner edge, the bottom layer formed from extending the top layer to fold under and be positioned flat against the top layer, the bottom layer extending from the inner edge outwardly toward the annular side wall to an outer edge of the bottom layer,
• wherein the top layer and bottom layer of the lip portion comprise a combined thickness within a range of 0.5 millimeters to 2.0 millimeters,
• wherein the inner edge of the lip portion forms a second circular opening having a second diameter, the first diameter being larger than the second diameter, the second circular opening sized to enable removable coupling of the lid portion to a mouthpiece portion of the fluid dispenser system, the mouthpiece portion having a sealing portion and a protruding end extending therefrom sized and configured to engage a human oral cavity, the mouthpiece portion having an aperture configured to be in fluid communication with the inner chamber of the stainless steel container portion,
• wherein the top layer and the bottom layer are configured to be in contact with the sealing portion of the mouthpiece portion when the lid portion is coupled to the mouthpiece portion and container portion in a fully seated position,
• wherein the outer edge of the bottom layer is sized such that when the lid portion is coupled to the mouthpiece portion and container portion in the fully seated position, a first annular contact region between the sealing portion of the mouthpiece portion and the top rim of the container portion is positioned outwardly of the outer edge of the bottom layer,
• wherein the top layer is shaped such that, when the lid portion is coupled to the mouthpiece portion and container portion in the fully seated position, a second annular contact region between the top layer and the sealing portion of the mouthpiece portion extends outwardly be and the first annular contact region.
