Abstract: A cap may be used in combination with a container including a dispenser. The cap may include three walls, such as an outer wall, an intermediate wall, and an inner wall. The cap may be adapted for contacting and/or frictionally engaging the dispenser. An opening such as an aperture may be provided for receiving the dispenser, and the inner wall may form a cavity of a similar size and shape as the dispenser for ensuring an effective fit.

Abstract: A molding system and related method for forming a molded article, such as a container, is disclosed. In one embodiment, the injection material is supplied though a side gate and drawn into the mold cavity using a vacuum assist and optional heating of the mold portions, if necessary. This creates a preform having a closed end with a smooth outer surface without gate marks or other vestiges of the injection molding process. The preform is then blow molded to form an article or container having a smooth outer surface adjacent to a closed end thereof.

Abstract: A composite container with an integral support, as well as a mold and method for forming such a container, are disclosed. The support may include a first end having a plurality of radially extending slits communicating with a central bore. Hence, when the support is placed in or adjacent to the mold cavity during a blow molding process, a portion of the parison or preform undergoing blow molding penetrates into in at least one, are preferably each of the slits and the bore to form a secure connection. A second end of the support may include a leg for mating with a base. The base may be integrally formed with the leg, or may be separately attached after the blow molding process is complete.

Abstract: A composite plastic container is formed by blow molding a body from a plastic parison into a base having a bottom, side walls and an open top, which includes an upper annular edge. A peripheral shoulder defines the upper portion of the body. The double side walls and bottom are relatively thick for strength and stability; the bottom also including a substantially solid rim in alignment with the annular edge for enhanced stability. A central opening in the bottom forms a plastic plug to anchor the bottom to the base. The lip of the shoulder mates and substantially covers the annular edge forming a smooth, rounded interface in the preferred embodiment. The peripheral lip can mate in other ways with the annular edge. Other features include an insert label and a protrusion in a side wall to form a window.

Abstract: A plastic container is formed by injection and blow molding wherein the injection molded body has an annular shoulder, an upper neck and a bottom wall with a central flat portion of substantially the same thickness as the wall of said body. An enlarged annular corner portion connects the bottom wall to the body and extends downwardly. The annular corner is sufficiently thick so as to form a substantially solid rim after bi-axial stretching during blow molding. The plastic parison for forming the container includes a body with an annular shoulder and an upper neck and also with the bottom wall having a central flat portion of substantially the same thickness as the body. The enlarged annular corner portion of the parison also connects to the body and extends downwardly to form a substantially solid rim. The thickness of the annular corner is sufficient to keep the annular corner from having a cavity formed in it during bi-axial stretching.
