Description

Attorney Ducket No. 0899-0017 HOT FILL~CONTAINER AND CLOSURE AND ASSOCIATED METHOD
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a method for hot filling containers and, more particularly, to a hot-filling method and an associated container or closure.
[0002] In order to maintain product quality and consumer safety, most foodstuffs are packaged in a hot-fill operation in which the foodstuffs are placed in the containers while hot. During filling, the container subjected to elevated temperatures (i.e., the product temperature, which is typically on the order of 82 °C, or higher) , sealed, and then cooled.
[0003] Hot-filling is commonly used in the bottling of beverages, such as fresh or frozen drinks, fruit juices, isotonic (sports) beverages, etc. These products are Attorney Locket No. 0899-0017 typically packaged in PET bottles, which are light, tough, and well suited to the lifestyles of today's consumers.
[0004] The design of PET bott:Les for use in hot-fill operations is not a simple matter. At elevated temperatures, PET softens and loses its shape. The bottles are subjected to hydrostatic pressure exerted on the sidewalls of the container by the weight of the hot liquid, causing the sidewalk to bulge outwardly, During capping, further swelling of the container occurs as the air in head space expands. Finally, as the bottle cools, the volume of the contents, both liquid and air, contracts, causing the bottle sidewalls to collapse inwardly.
[0005] To prevent excessive or uncontrolled distortion of the container upon cooling, hot-fill containers are commonly formed with vacuum panels in the middle portion of the sidewalls. As a container is cooled, the vacuum panels move inwardly to accommodate the vacuum formed in the interior of the container.
[0006] The need for vacuum panels complicates meeting other packaging requirements, such as providing the mid-section of the bottled with consumer information, promotional graphics, and a grippable profile. Vented container closures incorporating hydrophobic membranes (i.e., membranes that allow air but not liquid to pass therethrough) are known. Their use would relieve tk:e Attorney wcket No. 0899-0017 negative internal pressure experienced during container cooling and still seal the container against leakage.
However, because such vented caps a:Lso permit gaseous fluids to migrate into the heads space of the bottle, both the quality (e.g, the taste profile) and the safety of the contents could potentially be compromised.
[0007] Accordingly, it is an object of the present invention to provide a method for hot-filling PET containers that provides for venting during cooling and an air tight seal thereafter.
[0008] It is a related object to provide a PET container andJor closure that can be used in the method.
SUMMARY OF THE INVENTION
[0009] These objects, as well as others that will become apparent upon reference to t2-ie following Detailed Description and accompanying drawir,~gs, are achieved by a method for hot-filling and capping a polymer container in which either the closure for the container or the head space area of the container is provided with a hole covered with a hydrophobic air permeable membrane. The container is then filled with a hot liquid and the cap is applied to the filled container. The filled container is then cooled with the pressure between the interior o~f the container and the ambient pressure being equalized due to the flow of ai:
across the air permeable membrane. Subsequent to cooling, __ . , .-:t,~. ~.,.~,~~.:~~,~_~~u~,-~,~..~..~,. ~~..~...~.w..__ . .._.._ _...___ ._..._._ _...__. . _. _.

Attorney ~~cket No. 0899-0017 an air-tight seal is provided over the membrane-covered hole. An associated container and/or closure cap that is~
used in the method is also disclosed.
BRIEF DESCRIPTION OF THE FIGURES OF THE DRAWING
[00010] Fig. 1 is a partial fragmentary view of a vented container/closure in accordance with the present invention.
[00011] Fig. 2 is a partial fragmentary view of a vented container/closure in accordance with the present invention with the vent being sealed.
DETAILED DESCRIPTION
[00012] Turning to the drawings, there is seen a container 10 tin partial fragmentary view) and its associated closure Z8 in accordance with the present invention. Specifically, in Fig. 1, the shoulder and neck portion of a vented polymeric bottle or container and closure cap is shown with vent being open, while in Fig. 2, the vent is sealed.
[00013) The container 10 includes, starting at the top, an open mouth 12 defined by a neck finish 14. The neck finish 14 of this embodiment includes external threads 16 for receiving the screw-on closure cap 18 and a rib 20 for retaining a tamper-evident ring 22 that is frangibly attached to the closure cap 18.
[00014] Beneath the neck finish 14, the container 10 includes a shoulder portion 24 that generally increases in Attorney L"cket No. 0899-0017 diameter from the neck finish 14 to the container mid-section (not shown), which can be of a generally cylindrical configuration. The container mid-section, in turn, terminates in the container base (also not shown).
[00015] As is well-known, the container 10 is typically blow molded from an injection-molded preform that may be made from various polymer resins, such as polyesters,.
polyolefins, polycarbonates, nitrites and copolymers.
thereof. Bi-axially oriented polyethylene terephthalate (PET) is commonly used.
[00016] The closure cap 18 typically comprises a polymer shell 26 with a top surface 28 with a skirt 30 depending therefrom. Examples of suitable polymers include polypropylene or polyethylene polymer. The skirt includes internal threads 32 for mating with the external threads 16, provided on the neck finish 14. The underside of the top surface 28 of the closure cap 18 may optionally include a liner 34 made of a resilient material for sealing the interfacing surfaces of the closure cap 18 and the container lip. Alternatively, the closure cap 18 may be linerless.
[00017] In order to permit the equalization of pressure between the container interior and the ambient atmosphere during cooling of the container after hot filling, the closure cap is provided with a through-hole 36 in its tc~
surface and associated liner 34. Alternatively, the hole '~

Attorney Locket No. 0899-0017 _6_ can be located in the skirt portion 36 or the cap 18. The hole 36 has a diameter on the order of 50 microns to 100 microns. The through-hole 36 is covered on its interior side with a membrane 38 made of a hydrophobic, air permeable material, such as expanded polytetraflouro-ethylene (ePTFE?
or polypropylene, that serves as a vent. The vent membrane 38 has a porosity of between about 20 percent and 40 percent, and preferably 30 percent, with an average pore size of from about 0.3 to 5.0 microns. Preferably, the pore size is from about 0.4 to 2.0 microns, and, more preferably from about 0.5 to 1.5 microns. In practice, an average pore size of about 1.0 micron has been found to provide satisfactory results.
[00018] In keeping with the invention, the vent membrane 38 is provided with a seal 40 after the contents of the bottle has been cooled to ambient temperature. The seal 40 prevents any further ingress or egress of gaseous fluids with respect to the interior of the cantainer 10. The seal 40 can be any food grade material that forms both an oxygen and moisture barrier, and may be in the form of a coating, such as a W activatable material, a composition which solidified upon exposure to actinic radiation, paint, or semi-transparent adhesive that the seal 40 fills the hole 36 resulting in the seal 40 being flush with the top surface 28 of the closure cap 18. Alternatively, the seal 40 may .._____....~~,~~,~s, ~.,v ,<M_~,.~,~~~~~~-~.~~ ~,~ .___..__ ._...,._.__.__._a.....,..x..~.".. ._,_._.,~..~.__._ Attorney Docket No. 0899-0017 comprise an air-tight plastic membrane with a pressure-sensitive adhesive on one side that is applied over the hole 36 on the outside of the top surface 28 on the closure cap 18.
(00019] In an alternative embodiment, the container itself can be provided with the vent, rather than the closure cap. As seen in the drawings, the container 10 may include a through-hole 136 in its shoulder portion above the liquid level or fill line 42 of the container 10. The through-hole 136 is provided with a 'vent membrane 138 disposed on the interior of the container 10, which is provided with a seal 140 after cooling, all as described above.
(00020] Based on the foregoing, the method of the present invention should be self-evident. Either the cap or the.
shoulder portion of the container above the fill line is provided with a through-hole that is covered with a hydrophobic, air permeable membrane. When the container is filled with a hot liquid and the cap is applied to the filled container. The container is then cooled to ambient temperature. During cooling, air can pass through the membrane to permit equalization between the pressure on the interior of the container and ambient pressure. After cooling, an air-tight seal is applied over the membrane-covered hole, thus preventing any further migration of air . .. .... ~x..~ ~ ~r ~: ~"~~_ .,~:. ,~,"~~~:~.~~.,,.g, enri. ~.~~w , ._ ._~..

Attorney _~cket No. 0899-0017 across the membrane and resulting in a container having a substantially air--tight, as well as liquid-tight, seal..
[00021] Thus, a hot fill method a.nd associated container or closure has been provided that meets the objects of the present invention. As a result, the container no longer requires the deformable vacuum panels in its body portion that are commonly found in hot-fill polymer containers.
With the vacuum panels eliminated, the design of the container is greatly simplified and, for example, a functionally grippable profile is more easily provided.
[00022] While the invention has been described in terms of certain preferred embodiments, there is no intent to limit the invention to the same. Indeed, while the invention is shown in connection with a polymer bottle, the vent membrane and seal may also be used on other types of aseptic, hot-fill containers, such as pouches and boxes.
Consequently, the invention is defined by the scope of the following claims.
