Abstract
A structure, such as a tabletop, may be constructed from blow-molded plastic. The tabletop may include an upper surface, a lower surface, and a hollow interior portion disposed between the upper surface and the lower surface. A lip may extend downwardly relative to the lower surface of the tabletop, and the lip including an outer surface and an inner surface. One or more supports may be disposed in the inner surface of the lip, and one or more joints may be disposed in the inner surface of the lip. A joint may be disposed between adjacent supports, and a distal portion of the lip may include a compression edge. A lower portion of the supports may contact the compression edge, and/or a lower portion of the joints may contact the compression edge.
Claims20
A blow-molded plastic structure comprising:
- a tabletop including an upper surface, a lower surface, and a hollow interior portion disposed between the upper surface and the lower surface of the tabletop;
- a lip extending downwardly relative to the lower surface of the tabletop, the lip including an outer surface and an inner surface;
- at least two supports disposed in the inner surface of the lip;
- one or more joints disposed in the inner surface of the lip, a joint of the one or more joints disposed between adjacent supports of the at least two supports, the joint disposed between the adjacent supports at least substantially prevents fluid flow between the adjacent supports;
- and
- a compression edge disposed in a distal portion of the lip between the adjacent supports of the at least two supports.
A molded plastic tabletop comprising:
- an upper surface;
- a lower surface;
- a hollow interior portion at least partially disposed between the upper surface and the lower surface of the tabletop;
- a lip extending downwardly relative to the lower surface of the tabletop, the lip including an inner surface;
- two or more supports disposed in the inner surface of the lip;
- one or more joints disposed in the inner surface of the lip, wherein a joint of the one or more joints is disposed between a pair of adjacent supports of the two or more supports;
- and
- a compression edge disposed in at least a portion of the lip;
- wherein a portion of one or more of the supports contacts the compression edge;
- and
- wherein a portion of one or more of the joints contacts the compression edge.
A molded plastic tabletop comprising:
- an upper surface;
- a lower surface;
- a hollow interior portion at least partially disposed between the upper surface and the lower surface of the tabletop;
- a lip extending downwardly relative to the lower surface of the tabletop, the lip including an inner surface;
- a plurality of supports disposed in the inner surface of the lip;
- and
- a plurality of joints disposed in the inner surface of the lip;
- wherein an average height of the plurality of supports is generally equal to an average height of the plurality of joints.
