Abstract
Description
- Reference is made to copending application Ser. No. 10/329,666 filed Dec. 24, 2002.
- The present application is directed to plastic containers and preforms for blow molding plastic containers, and more particularly to a method of forming internal threads on the preform or container finish.
- In the manufacture of plastic containers, such as monolayer or multilayer polyethylene terephthalate (PET) containers, it is conventional to mold a container preform having a body and a finish with one or more external threads. The finish typically is molded to its final geometry in the preform, while the body of the preform is subsequently blow molded to the desired geometry of the container body. However, this manufacturing technique is not well suited for fabrication of preforms or containers having internal threads because, among other reasons, it is difficult to strip a preform having molded internal threads from its forming mold. It is therefore a general object of the present invention to provide a method of forming internal threads in the finish of a molded plastic preform or container, and to provide a preform or container finish manufactured in accordance with such method.
- A method of making a plastic container having a body and an internally threaded finish, in accordance with one presently preferred aspect of the invention, includes providing a preform of molded plastic construction having a body and an integral neck, and expanding the body of the preform within a mold cavity to form the body of the container. Either prior to or subsequent to blow molding the container body, at least one internal thread is formed in the neck by engaging an inner surface of the neck with a first rotary tool having a peripheral channel, engaging an outer surface of the neck with a second rotary tool having a peripheral bead, and causing rotation of the neck and tools to swage at least one internal thread in the neck.
- The invention, together with additional objects, features, advantages and aspects thereof, will be best understood from the following description, the appended claims and the accompanying drawings, in which:
-
FIG. 1 is a perspective view of a container preform molded without threads in accordance with one aspect of the present invention; -
FIG. 2 is a schematic diagram that illustrates swaging internal threads in the preform ofFIG. 1 ; -
FIG. 3 is a schematic diagram that illustrates swaging internal threads in a container molded from the preform ofFIG. 1 ; -
FIG. 4 is a sectional view of the portion ofFIG. 3 within thearea 4; -
FIG. 5 is an exploded fragmentary perspective view of a preform or container finish assembly having both internal and external threads in accordance with another aspect of the present invention; -
FIG. 6 is a schematic diagram that illustrates swaging internal threads in a preform having molded external threads; and -
FIG. 7 is a sectional view of a preform having molded external threads and swaged internal threads. -
FIG. 1 illustrates an exemplary container preform 10 having abody 12 and anintegral neck 14.Neck 14 preferably is cylindrical in contour, and has no internal or external threads in this embodiment as molded. Thespecific preform 10 illustrated inFIG. 1 is molded with anexternal stop bead 16 for cooperating with tamper-indicating structure in a closure secured to the final container, and asupport flange 18 that facilitates handling of the preform and the container.Bead 16 andflange 18 are optional.Cylindrical neck 14 is of generally uniform radial wall thickness. Preform 10 can be injection molded or compression molded of monolayer plastic construction such as PET, or of multilayer plastic construction having matrix or structural layers of PET, for example, and one or more intermediate layers of barrier material such as ethylene vinyl alcohol (EVOH) or nylon. The barrier layers may or may not extend intopreform neck 14. - In accordance with one aspect of the present invention, internal threads are swage-formed in
neck 14 either prior to or subsequent to blow moldingpreform body 12. As illustrated inFIG. 2 , one or moreinternal threads 20 are swaged inpreform neck 14 prior to blow moldingpreform body 12. Thesethreads 20 are swaged into the preform neck by means of a firstrotary tool 22 that engages the inner surface ofneck 14, and a secondrotary tool 24 that engages the outer surface ofneck 14.Inner tool 22 includes adisk 26 with aperipheral channel 28.Outer tool 24 includes adisk 30 having a peripheral bead orrib 32. Withtool 22 in engagement with the internal surface ofneck 14 andtool 24 engaged with the external surface ofneck 14, the tools (and preform) are rotated so that bead 32 deforms or swages the plastic material ofneck 14 intochannel 28 ontool 22. This deformation can be assisted and promoted, if desired, by heating one or both of thetools internal threads 20 are formed inneck 14,preform 10 is placed in a suitable blow mold, and preformbody 12 is blow molded to form thebody 12 a (FIG. 3 ) of a container. -
FIG. 3 illustrates an alternative technique for swaginginternal threads 20 inpreform neck 14 after blowmolding container body 12 a. Reference numerals inFIG. 3 that are identical to those inFIGS. 1-2 indicate identical parts. Whether the internal threads are swaged in the preform neck prior to or subsequent to blow molding the preform body, theneck 14 remains of substantially uniform radial thickness as illustrated inFIG. 4 . -
FIG. 5 illustrates a method of forming a preform or container having both internal and external threads in the preform or container finish. After swaging one or moreinternal threads 20 into theneck 14 of the preform or container (FIG. 2 orFIG. 3 ), a separately madefinish ring 34 is secured over the external surface ofneck 14.Finish ring 34 has one or moreexternal threads 36 preformed therein. As a modification toFIG. 5 , stopbead 16 and/or supportflange 18 may be formed inring 34 rather than in the preform. Thus, the final container in accordance with the embodiment ofFIG. 5 includes both internal and external threads, with the internal threads being swaged into the container neck and the external threads being formed on a separate finish ring. -
FIGS. 6 and 7 illustrate another method of making a preform having both internal and external threads. In thispreform 40, the preform is molded withexternal threads 42 on thepreform neck 44. After molding, and either prior to or subsequent to blow molding the preform body,swage tools internal threads 46 onneck 44. - It may be desirable to heat
neck 14 during the thread forming operation. This heating preferably is carried out by conduction fromtools neck 14 has a thickness of 0.5 to 1 mm (0.019 to 0.039 inch). A lesser contact time, such as on the order of one second, may not be adequate unless the finish neck is very thin, which would not be desirable in the embodiments ofFIGS. 1-4 but could be accommodated in the embodiment ofFIG. 5 . - Thus, one or more internal threads are swage formed on the E wall of preform and
container neck 14. All or a portion of the preform or container neck can be crystallized before or during formation ofinternal threads 20 to prevent shrinkage or distortion. This would be particularly desirable in hot-fill applications, where the temperature of the material placed in the container otherwise might cause shrinkage or distortion of the container finish. Crystallization of the container finish can extend throughout the radial thickness and the axial length of the neck, includingstop bead 16 and/or supportflange 18 where provided, if desired. - There have thus been disclosed a preform, a container and a method of manufacture that fully satisfy all of the objects and aims previously set forth. The preform, container and method of manufacture have been disclosed in conjunction with several presently preferred embodiments thereof, and a number of modifications and variations have been discussed. Other modifications and variations will readily suggest themselves to persons of ordinary skill in the art. For example, tooling can be provided on
rotary tools neck 14. The invention is intended to embrace all such modifications and variations as fall within the spirit and broad scope of the appended claims.
