FIG. 1.8 is a perspective view of the cap-on-cap container lid of FIG. 1.1 with the upper cap detached from and positioned to the side of the lower cap.
The dash-dash broken lines illustrate portions of the cap-on-cap container lid and form no part of the claimed design.
The design includes a strap that couples an upper cap to a lower cap. The perspective view of FIG. 1.1 shows the upper cap secured to and covering a spout portion of the lower cap. The perspective view of FIG. 1.8 shows the upper cap removed from the spout portion of the lower cap and stored to the side of the spout. The spout cannot be seen in FIG. 1.1 but is seen in FIG. 1.8. The position of the upper cap relative to the lower cap may vary within the constraints of the strap.
