    摘要： The present invention relates generally to improvements in plastic preforms adapted for telescopic association with a complementary smooth surfaced mandrel such as is used in conventional plastic blow molding machines. More particularly, the present invention contemplates a novel type of plastic preform as herein, which comprises an elongate hollow plastic member, the inner surface of which in the aggregate conforms generally with the shape defined by the smooth peripheral surface of a complementary mandrel. The inner peripheral surface of the hollow plastic member or preform below the rim portion presents a plurality of circumferentially spaced surface portions adapted for initial direct impingement with restricted areas of the peripheral surface of a complementary smooth surfaced mandrel, the spacing between the said surface areas of impingement providing passageways extending generally longitudinally throughout substantially the entire longitudinal extent of the plastic member. The inner rim portion is devoid of such surface areas of impingement for air sealing the preform on the mandrel.

    摘要： A preform (10) for producing a plastic preform for forming blow molded plastic containers which comprises: a neck portion (16) defining an opening; a tubular sidewall portion (24) depending therefrom; and an integral base structure (28) depending from the tubular sidewall portion to a closed end (32); the preform having an outside wall face and an inside wall face with one of these, in the base structure, having integrally formed thereon a plurality of filets (36), extending longitudinally of the preform and defining a reinforcement (38) of varying thickness spaced from the closed end and circumscribing the base structure, wherein the filets decrease progressively in width and radial thickness at least from the reinforcing ring toward the closed end. The preform is capable of forming a blow molded plastic container with a bottom portion (130) having a reinforcement of circumferentially continuous radially extending alterations in wall thickness with a regularly undulating cross-section along the circumference. Preferably the filets are integral with the inside wall face. The invention also covers a mold-core rod combination for making such a preform, a process of using such a preform to make plastic containers by stretch/blow molding and containers including containers when produced from said preforms or combinations, or by said process.

    摘要： A plastic blank includes a blank structure. The blank structure includes an elongate body portion and a head portion. One of two ends of the body portion is closed, and the head portion is connected to the other end of the body portion. The body portion has a space therein. The head portion has an opening communicating with the space. The outer periphery of the body portion is even so that a stick having product labelling can be attached onto the outer periphery of the body portion. The inner periphery of the body portion has a plurality of ribs protruded inward the space and extending along the body portion to improve the structural strength of the body portion along the length direction.
