Abstract
A method making a plastic container in accordance with one aspect of the present invention includes molding an intermediate container product having a body and a moil integral with the body. The body is of layered construction that includes at least one layer of barrier resin that extends part-way into but not throughout the moil. The upper portion of the moil, in which the barrier material is absent, is removed for recycling as process regrind. The lower portion of the moil is removed to form the container. In the preferred embodiment of the invention, the upper portion of the moil is removed in a laser trimming operation. The lower portion of the moil is removed in the preferred embodiment of the invention by inserting a plug into the open end or mouth of the container, and employing a cutting tool that is positioned by the plug for accurately trimming of the container product with respect to the mouth of the container. The cutting tool preferably is either a pair of shear rollers or a laser cutting tool.
Description
- The present invention relates to fabrication of multilayer plastic containers, and more particularly to removal of a moil or dome from the container after blow molding.
- In the fabrication of certain types of containers, particularly wide-mouth containers, it is conventional practice to blow mold an intermediate container product from a preform, and then to remove the upper portion of the intermediate product, referred to as a dome or moil, in a post-molding operation. U.S. Pat. No. 4,576,843 discloses a container manufacturing method of this type, in which the moil is removed by knife blades carried by the blow mold sections. It has also been proposed to fabricate containers of the subject type having a multilayer or laminated sidewall that includes one or more intermediate layers of barrier resin such as ethylene vinyl alcohol (EVOH) or nylon. U.S. Pat. No. 4,550,043, for example, discloses a process for making a preform for such a container, in which the intermediate barrier layer can be controlled to extend only part-way through the preform and the intermediate container product.
- Problems are encountered when making containers of this type. For example, it is difficult to control placement of the edge of the intermediate barrier layer exactly at the moil trim line, so that the barrier layer must be made to extend into the moil to ensure that the barrier layer extends throughout the final container product. This, however, compromises the ability to use the trimmed moil as process regrind inasmuch as it is undesirable to have barrier material in the process regrind. Furthermore, the use of knife blades to trim a multilayer container product is undesirable because the blade can cause delamination at the trim line, and because the knife blade is subject to excessive wear when used in combination with abrasive container layer materials such as polyethylene terephthalate (PET). U.S. Pat. No. 4,549,066 discloses the use of a laser for performing the trimming operation, which reduces the delamination and wear problems.
- A method making a plastic container in accordance with one aspect of the present invention includes molding an intermediate container product having a body and a moil integral with the body. The body is of layered construction that includes at least one layer of barrier resin that extends part-way into but not throughout the moil. The upper portion of the moil, in which the barrier material is absent, is removed for recycling as process regrind. The lower portion of the moil is removed to form the container. In the preferred embodiment of the invention, the upper portion of the moil is removed in a laser trimming operation. The lower portion of the moil is removed in the preferred embodiment of the invention by inserting a plug into the open end or mouth of the container, and employing a cutting tool that is positioned by the plug for accurately trimming the container product with respect to the mouth of the container. The cutting tool preferably is either a pair of shear rollers or a laser cutting tool.
- 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 side elevational view of a plastic container with lid in accordance with one exemplary embodiment of the invention; -
FIGS. 1A and 1B are fragmentary sectional views of the portions ofFIG. 1 within therespective areas -
FIG. 2 is a schematic diagram that illustrates a container intermediate product being subjected to a first trimming operation in accordance with the exemplary embodiment of the invention; -
FIG. 3 is a schematic diagram that illustrates the container intermediate product being subjected to a second trimming operation in accordance with the exemplary embodiment of the invention; and -
FIG. 4 is a fragmentary perspective schematic view of the trimming operation illustrated inFIG. 3 . -
FIG. 1 illustrates apackage 10 in accordance with one exemplary embodiment of the invention as including acontainer 12 to which alid 14 is secured.Container 12 is of multilayer construction, having at least one outer or structural layer and at least one intermediate layer of barrier resin material. In the specific three-layer embodiment illustrated inFIGS. 1A and 1B , the container has anintermediate layer 16 sandwiched between inner andouter layers Layers intermediate layer 16 may be of barrier resin such as EVOH or nylon. Another exemplary construction would be a five-layer construction in the form PET/barrier/PET/barrier/PET.Barrier layer 16 extends throughout the body ofcontainer 12 to the edge of aflange 22 that projects radially outwardly from the open mouth of the container.Lid 14 may be of suitable metal construction, and may be crimped overflange 22 in a double-seam crimp configuration. -
Container 12 is formed from a blow molded intermediate container product 24 (FIG. 2 ) that includes the body ofcontainer 12 and an integrally molded dome ormoil 26. Containerintermediate product 24 may be fabricated by first injection or compression molding a container preform and then blow molding the preform. Intermediate barrier layer(s) 16 preferably do not extend entirely through the preform, so that theupper edge 16 a ofintermediate layer 16 is disposed within thelower portion 26 b ofmoil 26. After blow molding, theupper portion 26 a ofmoil 26 is removed or trimmed from the rest of containerintermediate product 24 by use of afirst trimmer 28, preferably a laser trimmer.Laser trimmer 28 is positioned to trimupper portion 26 a ofmoil 26 just above theupper edge 16 a of the barrier layer. The position of laser trimming preferably is set empirically based upon the maximum extent of the barrier layer into the moil. (It will be appreciated that words such as “upper” and “lower” are employed by way of description and not limitation with respect to the upright orientation of the container and container intermediate product illustrated in the drawings.) Theupper portion 26 a ofmoil 26 so removed bylaser trimmer 28 can thus be recycled as process regrind for formation oflayers - The container
intermediate product 24 is then subjected to a second trimming operation, which is illustrated schematically inFIGS. 3 and 4 . Atrimming tool 30 includes aplug 32 sized for insertion into the open mouth of containerintermediate product 24 afterupper moil portion 26 a has been removed. Acutter 34 is positioned by means of the plug, such as by being physically coupled to the plug, to engage theflange 22 ofcontainer 12. In one presently preferred embodiment of the invention illustrated schematically inFIG. 4 ,cutter 34 comprises a pair ofshear rollers flange 22 respectively. Thus, the radially outer edge offlange 22 is trimmed on a circle that is accurately located with respect to the axis ofplug 32, and thus with respect to the open mouth ofcontainer 12 into whichplug 32 is received. Thelower portion 26 b ofmoil 26 is thus removed in this second trimming operation. As a modification to the preferred embodiment illustrated inFIGS. 3 and 4 ,shear rollers plug 32, or is mounted on separate support structure for engaging and thus being accurately positioned with respect toplug 32. Moillower portion 26 b removed bycutter 30 may be scrapped, or may be used as process regrind in non-food applications. - There have thus been disclosed a method of making a plastic container, and a resulting container, that fully embody all of the objects and features discussed above. The invention has been disclosed in conjunction with an exemplary presently preferred embodiment 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. The invention is intended to embrace all such modifications and variations as fall within the spirit and broad scope of the appended claims.
