  • Publication number: 20220009222
    Abstract: A seal member includes an annular seal body extending about a flow axis. The seal body has a first sealing face, second sealing face, and a step face. The first sealing face extends radially from the flow axis and has a planar contour. The second sealing face extends radially from the flow axis, is axially opposite the first sealing face, and has an arcuate contour. The step face extends radially from the flow axis and is defined axially between the first sealing face and the second sealing face, the step face arranged for capture between a spout and a reservoir body to capture the seal member. Fluid reservoirs and methods of making fluid reservoirs are also described.

  • Patent number: 10654284
    Abstract: In one example in accordance with the present disclosure a fluid storage device is described. The device includes a fluid reservoir to store fluid. The fluid reservoir includes a free fluid chamber and an overflow chamber in fluid communication with the free fluid chamber. The reservoir also includes a seal assembly to, when in a first position, seal a refill port of the free fluid chamber and open an air vent of the overflow chamber. When in a second position, the seal assembly opens the refill port and seals the air vent.
