At least one blow-molded plastic container and one compression molded lid are simultaneously produced in a blow mold. Preferably, the method and apparatus utilize a mold capable of simultaneously receiving a pair of extruded parisons. One of the parisons is utilized to produce a pair of aligned container bodies and the other of the parisons is utilized to form a pair of aligned closures. In this manner, a container and closure combination can be manufactured having perfect color matching and can be readily recycled in its entirety. In addition, the method and apparatus according to the present invention significantly reduces tooling costs and required machine capitol.

A squeezable tube-shaped plastic container ( ) having a one-piece construction formed by extrusion blow-molding techniques. The container ( ) has a retractable end wall ( ) which is positionable into an outwardly projecting position and an inverted position. The end wall ( ), as blown, is in the outwardly projecting position and is thereafter inverted so that a tamper indicating covering ( ) can be attached to the end ( ) of the container ( ) thereby sealing the end wall ( ). The inverted end wall ( ) permits the container ( ) to be free standing on the standing ring ( ). In use, the flexible sidewall ( ) of the container ( ) is squeezed to snap the end wall ( ) from the inverted position to an outwardly projecting position to enable ready access to a dispensing opening ( ) on the end wall ( ). An efficient and cost effective method for forming the container ( ) and an intermediate article ( ) formed during the method are also disclosed.

A container base may include a standing ring defining a touch point for contact with a horizontal surface, where the standing ring has an outer portion and an inner portion, and merges with the container sidewall. The base may also have a stacking ring having an inner portion and an outer portion, where the outer portion merges with the inner portion of the standing ring. The base may further have a substantially circular recessed portion coupled to the inner portion of the stacking ring, comprising: a plurality of substantially flat concentric rings recessed from the stacking ring, wherein each ring is recessed from the next outermost adjacent ring; a substantially flat center coupled to an inner diameter of an innermost substantially flat ring and recessed therefrom; and a cross-brace extending from the stacking ring into the substantially flat center.

A tube is provided for containing a product to be squeezed from the tube when the tube is used in conjunction with a wrapping tool. The tube has a deformable main body for storing the product prior to the product being squeezed from the tube, the main body having a longitudinal direction, a transverse direction perpendicular to the longitudinal direction, a first end and a second end opposite the first end in the longitudinal direction of the main body. The tube has an opening at the first end of the main body, the opening being an outlet for the product when the product is squeezed from the tube, and a seal at the second end of the main body, the seal having a contour, the contour having a bearing surface that is non-parallel to the longitudinal direction of the main body. The bearing surface is for receiving a wrapping force from the wrapping tool for wrapping the main body around the seal.
