Molded plastic structures

A blow-molded plastic structure constructed using a blow-molding process, the blow-molded plastic structure comprising:

• a panel including an upper surface, a lower surface, and a hollow interior portion;
• an outwardly extending lip including an outer surface and an inner surface;
• a first blow point receiving portion at least partially disposed in the inner surface of the lip, the first blow point receiving portion being sized and configured to receive a blow pin during the blow-molding process;
• a second blow point receiving portion at least partially disposed in the inner surface of the lip, the second blow point receiving portion being sized and configured to receive a blow pin during the blow-molding process;
• and
• a continuous tack-off extending between the first blow point receiving portion and the second blow point receiving portion.

A blow-molded plastic structure constructed using a blow-molding process, the blow-molded plastic structure comprising:

• a panel constructed from blow-molded plastic, the panel including an upper surface, a lower surface, and a hollow interior portion, the upper surface, the lower surface, and the hollow interior portion being integrally formed as part of a unitary, one-piece structure;
• an outwardly extending lip including an inner surface and an outer surface;
• a plurality of blow point receiving portions at least partially disposed in the inner surface of the lip, the blow point receiving portions being sized and configured to receive a blow pin during the blow-molding process;
• a plurality of fastener receivers at least partially disposed in the inner surface of the lip, the fastener receivers being sized and configured to receive a fastener;
• and
• a continuous tack-off at least substantially disposed between the lip and the panel, the continuous tack-off extending between blow points of the plurality of blow points.
