Benefits of technology
[0003] In at least some instances, it may be desirable to form a container body separately from a neck finish and/or handle. One reason is that a neck finish that is integrally formed with a preform typically requires more accurate and stable dimensioning than the rest of body of the preform, which may limit the cycle time of the preform molding process. Another reason is that the blow molds used to form the container body can be more simple in de
Problems solved by technology
One reason is that a neck finish that is integrally formed with a preform typically requires more accurate and stable dimensioning than the rest of body of the preform, which may limit the cycle time of the preform molding process.

Embodiment Construction
[0021]FIG. 1 illustrates a preform 10 that includes a closed end 12 and an oppositely disposed open end 14. A body portion 16 extends from the closed end 12 toward the open end 14 and terminates in the form of a neck 18. The neck 18 extends upward from the body portion 16 to include an integral annular support flange 20, further extends upward to include integral first and second orienting beads or rings 22, 24 and terminates at the open end 14. For reasons that will be discussed below, the neck portion 18 of the preform 10, particularly that portion between the orienting rings 22, 24 inclusive, is preferably provided with knurling surface features. Knurling surface features are defined herein as a pattern of small ridges, beads, or cross-hatches provided on a surface to aid in gripping another surface to be placed in contact therewith. The preform 10 may be of monolayer construction, or may be of multilayer construction having an inner layer of barrier resin, for example, such as e...

Abstract
A method of making a container by providing a container having a neck, providing a container attachment having a circumferentially continuous ring, telescoping the ring over the neck, and radially expanding at least a portion of the neck to secure the attachment to the neck.
Description
[0001] The present invention is directed to manufacture of containers, and more particularly to the manufacture of plastic containers having components, such as finish rings and handles, assembled thereto. BACKGROUND AND SUMMARY OF THE INVENTION [0002] Containers for flowable products, such as liquids and granular products, have been formed of plastic by a variety of methods. For example, plastic containers have been blow molded from preforms to provide container bodies having integral neck finishes and handles. Also, plastic containers have been formed with a container body, including a neck finish integral with the container body, and a handle separately attached to the container. Other containers have been formed by positioning an injected molded handle and finish in a blow mold so that the handle and finish are incorporated into the container as it is blow molded. [0003] In at least some instances, it may be desirable to form a container body separately from a neck finish and / or...
