Definitions
- Embodiments of the present disclosure generally relate to the field of plastic bottles and preforms. More specifically, embodiments of the disclosure relate to tamper evidence container caps and preforms that provide visible indications of removal of the container caps after installation by a manufacturer.
- PET containers have been used as a replacement for glass or metal containers in the packaging of beverages for several decades.
- the most common plastic used in making beverage containers today is polyethylene terephthalate (PET).
- Containers made of PET are transparent, thin walled, and have the ability to maintain their shape by withstanding the force exerted on the walls of the container by their contents.
- PET resins are also reasonably priced and easy to process.
- PET bottles are generally made by a process that includes the blowmolding of plastic preforms which have been made by injection molding of the PET resin.
- plastic packaging include lighter weight and decreased breakage as compared to glass, and lower costs overall when taking both production and transportation into account.
- plastic packaging is lighter in weight than glass, there is still great interest in creating the lightest possible plastic packaging so as to maximize the cost savings in both transportation and manufacturing by making and using containers that contain less plastic.
- a plastic container for storing liquid contents typically includes a base that extends up to a grip portion suitable for affixing a label, as well as providing a location for grasping the container.
- the grip portion generally transitions into a shoulder, which connects to a bell.
- the bell has a diameter that generally decreases as the bell extends upward from the shoulder to a neck and a finish.
- the finish is adapted to receive a closure, such as a bottle cap, to seal the contents within the interior of the plastic container.
- the closure includes a tamper evidence band that is disposed around the perimeter of the finish.
- the tamper evidence band generally remains positioned on the finish when an end-user loosens the closure to access the contents within the container.
- the tamper evidence band and the finish cooperate to indicate to the end-user whether or not the closure has been previously loosened after being installed by the manufacturer.
- a drawback to conventional tamper evidence bands is that in some instances the tamper evidence bands fail to detach from the closure upon being loosened, thereby making it difficult for an end-user to directly observe whether or not the closure has been previously separated from the container. Consequently, the closure may be separated from the tamper evidence band, the container may be refilled, and another closure may be installed onto the container, giving little visual indication to the end-user that the container has been reused.
- a container preform and a tamper evidence closure are provided for reliably providing a visible indication about whether or not a manufacturer-installed closure has been previously removed from a plastic container.
- the container preform includes a finish portion for rotatably engaging with the tamper evidence closure to seal contents within an interior of a container formed from the preform.
- the finish portion comprises a cylindrical body that begins at an opening to the interior of the container and extends to and includes a tamper evidence ledge.
- One or more threads are configured to provide a means to fasten the tamper evidence closure to the container.
- a valley is disposed between the one or more threads and has an inner diameter.
- a handling valley is disposed between the one or more threads and the tamper evidence ledge.
- a finish portion of a preform for rotatably engaging with a tamper evidence closure to seal contents within an interior of a container formed from the preform comprises: a cylindrical body that begins at an opening to the interior of the container and extends to and includes a tamper evidence ledge; one or more threads configured to provide a means to fasten the tamper evidence closure to the container; a valley disposed between the one or more threads having an inner diameter; and a handling valley disposed between the one or more threads and the tamper evidence ledge.
- the tamper evidence ledge is configured to cooperate with a tamper evidence band of the closure to indicate whether or not the closure has been loosened after being installed by a manufacturer.
- the tamper evidence closure includes a tamper evidence band disposed around the circumference of the tamper evidence closure and attached thereto by way of a multiplicity of thin connections.
- the handling valley and a neck portion of the container are configured to enable gripping fingers to engage with and support the container during air- conveying the container along a manufacturing assembly.
- the handling valley provides a separation between the tamper evidence ledge and the one or more threads suitable for receiving a pair of gripping fingers of an air conveyor system.
- the valley disposed between the one or more threads has an inner diameter that is greater than the diameter of the handling valley. In another exemplary embodiment, the valley disposed between the one or more threads has an inner diameter that is equal to the diameter of the handling valley.

- the terms“about,”“approximately,” or“substantially” for any numerical values or ranges indicate a suitable dimensional tolerance that allows the part or collection of components to function for its intended purpose as described herein.
- articles, including preforms and tamper evidence closures for containers In some instances, conventional tamper evidence bands fail to detach from the closure upon being loosened, thereby making it difficult for an end-user to directly observe whether or not the closure has been previously separated from the container. Consequently, the end-user has little visual indication of whether the container has been reused.
- Embodiments disclosed herein provide a preform and a tamper evidence closure that reliably provides a visible indication about whether or not a manufacturer-installed closure has been previously removed from a plastic container.
- Figure 1 illustrates an exemplary embodiment of a preform 100 suitable for being blow-molded to form a container, or a plastic bottle, according to the present disclosure.
- the preform 100 preferably is made of material approved for contact with food and beverages such as virgin PET and can be of any of a wide variety of shapes and sizes.
- the preform 100 shown in Fig. 1 is of the type which will form a 12-16 oz. beverage bottle, but as will be understood by those skilled in the art, other preform configurations may be used depending upon the desired configuration, characteristics and use of the final article.
- the preform 100 may be made by injection molding methods, without limitation.
- Figure 2 illustrates a cross-sectional slice view ofthe preform 100 illustrated in Fig. 1, taken along a line 2-2.
- the preform 100 includes a finish portion 104 and a body portion 108, formed monolithically (i.e., as a single, or unitary, structure).
- the monolithic arrangement of the preform 100 when blow-molded into a bottle, provides greater dimensional stability and improved physical properties in comparison to a preform constructed of separate neck and body portions that are bonded together.
- the finish portion 104 begins at an opening 112 to an interior of the preform 100 and extends to and includes a tamper evidence ledge 116.
- the finish portion 104 is further characterized by the presence of one or more threads 120 configured to provide a means to fasten a closure, such as a cap, to the bottle produced from the preform 100.
- the threads 120 are configured to rotatably engage with similar threads disposed within the cap to provide a way to seal contents within the bottle.
- each of the threads 120 generally extends along a section of the circumference of the finish portion 104 and approaches the tamper evidence ledge 116.
- each of the one or more threads 120 begins at a thread start 124 and extends along an angular section of the finish portion 104.
- the thread start 124 is configured to guide the thread 120 into a space, or valley 128, between adjacent threads of the cap so as to threadably engage the cap with the finish portion 104.
- the threads 120 generally are disposed adjacently to one another and are spaced uniformly around the circumference of the finish portion 104.
- the thread starts 124 of adjacent threads 120 are spaced at substantially 120-degree intervals around the perimeter of the finish portion 104.
- more or less than three threads 120 may be incorporated into the finish portion 104 without deviating beyond the scope of the present disclosure.
- the body portion 108 includes a neck portion 132 that extends to a tapered portion 136 of the body portion 108.
- the tapered portion 136 comprises a smooth transition from a diameter of the neck portion 132 to a relatively smaller diameter of a cylindrical portion 140 of the preform 100.
- the cylindrical portion 140 is a generally elongate member that culminates in an end cap 144.
- the body portion 108 may be generally cylindrical, and the end cap 144 may be conical or frustoconical and may also be hemispherical, and the very terminus of the end cap 144 may be flattened or rounded.
- a wall thickness of the cylindrical portion 140 is substantially uniform throughout the cylindrical portion 140 and the end cap 144.
- a wall thickness of the tapered portion 136 generally decreases from the wall thickness of the cylindrical portion 140 to a relatively thinner wall thickness of the neck portion 132.
- the wall thickness of the cylindrical portion 140 is relatively greater than the wall thickness of the neck portion 132 so as to provide a wall thickness at the desired dimensions of a finished product after the preform 100 is blow-molded into the shape and size of a bottle.
- the wall thickness throughout most of the body portion 108 will depend upon the overall size of the preform 100 and the wall thickness and overall size of the resulting container.
- Figure 3 illustrates an isometric view of the finish portion 104 comprising the preform 100 illustrated in Figs. 1-2, according to the present disclosure.
- the finish portion 104 includes one or more threads 120 extending along sections of the circumference of the finish portion 104 and approaching the tamper evidence ledge 1 16.
- the threads 120 generally extend outward from the finish portion 104 such that a valley 128 is disposed between adjacent threads.
- the cross-sectional profile of the threads 120 is configured such that the threads advantageously engage with similar threads disposed within the cap for sealing contents within the container formed by blow-molding the preform 100.
- the valley 128 is configured to allow passage of a thread disposed in the cap to pass between adjacent threads 120 during tightening of the cap onto the finish portion 104.
- the finish portion 104 includes a bevel 148 disposed at the beginning of the opening 112.
- the bevel 148 is configured to enter into sliding contact with a sealing flange of a suitable cap so as to prevent contents from leaking out of the container formed from the preform 100.
- the bevel 148 may compress the sealing flange to a predetermined degree, thereby forming a tight seal suitable to retain pressurized contents within the container.
- the tamper evidence ledge 116 comprises a rounded upper portion 152 and a substantially flat lower portion 156.
- the rounded upper portion 152 facilitates passing a tamper evidence band of the cap over the tamper evidence ledge 116 during assembly of the cap onto the container.
- the flat lower portion 156 is configured to retain the tamper evidence band positioned below the tamper evidence ledge 116 during loosening of the cap. For example, when the cap is initially installed onto the container by a manufacturer, the tamper evidence band easily passes over the tamper evidence ledge 116 due to the rounded upper portion 152.
- the flat lower portion 156 When an end-user later loosens the cap, the flat lower portion 156 retains the tamper evidence band below the tamper evidence ledge 116, causing the tamper evidence band to break loose from the cap.
- the flat lower portion 156 of the tamper evidence ledge 116 and the tamper evidence band of the cap cooperate to indicate to the end-user that the cap has not been previously loosened after being installed by the manufacturer.
- the tamper evidence ledge 116 is not limited to being coupled with tamper evidence bands, as described above, but rather the tamper evidence ledge 1 16 may be configured to operate with any of various devices for indicating whether or not the container has been previously opened.
- valley 128 disposed between the tamper evidence ledge 116 and the threads 120 and further between the threads of the finish portion 104.
- the valley 128 comprises a portion of the finish portion 104 that has a wall thickness and a diameter that may be substantially similar to the wall thickness and diameter of the neck portion 132, and in an alternative may have a wall thickness and a diameter that is smaller than the wall thickness and diameter of the cylindrical portion 140 and the neck portion 132.
- a handling valley 160 is also utilized to enable gripping fingers to engage with and support the container during air-conveying the container along a manufacturing assembly.
- a first pair of gripping fingers can extend into the handling valley 160 to support the container at a first station of a manufacturing line. Then, upon being conveyed to a second station, a second pair of gripping fingers can extend around the neck portion 132, below the tamper evidence ledge 116, while the first pair of gripping fingers are removed from the handling valley 160. Similarly, upon arriving at a third station, a third pair of gripping fingers can engage with the handling valley 160 while the second pair of gripping fingers are removed from the neck portion 132.
- the container can be transported along the manufacturing line by altematingly engaging gripping fingers with the handling valley 160 and the neck portion 132.
- the handling valley 160 provides a separation between the tamper evidence ledge 1 16 and the threads 120 suitable for receiving the pair of gripping fingers, as described above.
- the separation must be large enough to allow the gripping fingers to easily pass between the tamper evidence ledge 116 and the threads 120.
- any of various separations, greater than the width of the gripping fingers may be disposed between the tamper evidence ledge 116 and the threads 120, without limitation and without deviating beyond the scope of the present disclosure.
- Figure 4 illustrates a cross-sectional view of a tamper evidence closure 164 suitable for being threadably engaged with the finish portion 104 of Fig. 3 to provide an indication of whether or not the closure 164 has been loosened after being installed by a manufacturer.
- the closure 164 includes interior threads 176 that are configured to engage with the threads 120 of the finish portion 104, as described above. As such, the interior threads 176 extend into the thread valleys 128 extending around the finish portion 104.
- a plug seal 168 of the closure 164 is configured to extend into the opening 1 12 and enter into a pressed relationship with the finish portion 104 whereby contents are sealed in the interior of a container formed from the preform 100 (hereinafter “container 100”).
- the closure 164 includes a tamper evidence band 166 that includes a segmented cam 200 and is disposed around the perimeter of the closure 164. The tamper evidence band 166 is attached to the closure 164 by a multiplicity of thin connections 204.
- the segmented ca 200 generally comprises an angled lower surface 208 configured to facilitate passing the tamper evidence band 166 over the threads 120 and the rounded upper portion 152 of the tamper evidence ledge 1 16 during assembly of the closure 164 onto the container 100.
- a relatively flat upper surface 212 of the segmented cam 200 is configured to engage with the flat lower portion of the tamper evidence ledge 116 and thus retain the tamper evidence band 166 engaged with the tamper evidence ledge 116 during loosening of the closure 164.
- the segmented cam 200 presses against the flat lower portion 156 of the tamper evidence ledge 116, breaking the thin connections 204 between tamper evidence band 166 and the closure 164.
- the tamper evidence band 166 remains positioned on the tamper evidence ledge 116 after the closure 164 is removed from the container 100.
- Multiple overhang portions 216 disposed above the segmented cam 200 of the closure 164 are configured to press against the rounded upper portion 152 of the tamper evidence ledge 116.
- the overhang portions 216 ensure that the tamper evidence band 166, once free of the closure 164, does not fall below the tamper evidence ledge 116 and reside around the neck portion 132 of the container 100.
- the tamper evidence band 166 cooperates with the tamper evidence ledge 116 to indicate to the end-user whether or not the closure 164 has been previously loosened after being installed by the manufacturer.
- Figure 5 illustrates a cross-sectional view of an exemplary embodiment of a finish portion 104 of a preform 100.
- a plurality of threads 120 are disposed around the finish portion 104 to threadably engage the cap with the finish portion 104.
- the plurality of threads 120 are configured such that the threads advantageously engage with similar threads disposed within the cap for sealing contents within the container formed by blow-molding the container 100.
- Between the plurality of threads 120 is at least a valley 128 that extends inwardly away from the outside edge of the thread 120 to form an inner edge 180 on the outside wall 182 of the finish portion 104.
- the inner edge 180 of the valley 128 has a diameter that is equal and/or greater than the diameter of the handling valley 160 immediately above the tamper evidence ledge 1 16.
- the valley 128 has a diameter that is equal to the diameter of the handling valley 160.
- the inner diameter of the valley 128 is greater than the inner diameter of the handling valley 160 between the tamper evidence ledge 1 16 and the threads 120.
