Patent Application
20230202704
The present application generally relates to plastic containers, particularly to plastic containers designed to hold liquids while resisting deformation.
Plastic 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 blow-molding of plastic preforms which have been made by injection molding of the PET resin.
Advantages of plastic packaging include lighter weight and decreased breakage as compared to glass, and lower costs overall when taking both production and transportation into account. Although 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, while still exhibiting good mechanical properties.
The bottling industry is moving in the direction of removing auxiliary packaging from cases or pallets. A case of bottles with film only and no paperboard is called a “film only conversion” or “lightweighting” of auxiliary packaging. The removal of supporting elements such as paperboard places additional stress on a bottle, which increases the structural demands on the bottle. In certain embodiments, a bottle design can provide one or more of the benefits of reducing bending and point loading failures. The disclosed design embodiments can alleviate the stresses during shipping and handling (including film only packaging) while maintaining ease of blow molding. In certain embodiments, a bottle design uses less resin for the same or similar mechanical performance, resulting in a lightweight product.
Embodiments of the bottle disclosed herein may use polyethylene terephthalate (PET), which has viscoelastic properties of creep and relaxation. As a plastic, PET and other resins tend to relax at temperatures normally seen during use. This relaxation is a time dependent stress relieving response to strain. Bending can provide exaggerated strains over what would be seen in tensile loading. Due to exaggerated strains, the relaxation in bending can be much more severe. Bending happens at multiple length scales. Bending can happen at the length scale of the bottle or on a small length scale. An example of the bottle length scale bending is a person bending the bottle in his/her hands, or bending experienced during packing in a case on a pallet. An example of the small scale is the flexing or folding of ribs or other small features on the wall of the bottle. In response to loads at the first, larger length scale, ribs flex at the local, smaller length scale. When they are held in this position with time, the ribs will permanently deform through relaxation.
Further, embodiments of the bottles disclosed herein may undergo pressurization. Pressure inside a bottle can be due to the bottle containing a carbonated beverage. Pressure inside a bottle can be due to pressurization procedures or processes performed during bottling and packaging. For example, a bottle can be pressurized to help the bottle retain its shape. As another example, the bottle can be pressurized with certain gases to help preserve a beverage contained in the bottle.
Embodiments of the bottles disclosed herein have varying depth ribs that achieve a balance of strength and rigidity to resist the bending described above while maintaining hoop strength, such as, for example, when pressure is not used or relieved. A collection of flattened and/or shallow depth ribs act as recessed columns in the body of the bottle that distribute bending and top load forces along the wall to resist leaning, stretching, and crumbling. The collection of flattened and/or shallow depth ribs can help the bottle retain its shape during pressurization, such as, for example, help inhibit stretching of the bottle when pressurized. Inhibiting stretching of the bottle helps retain desired bottle shape to aid in packaging of the bottles as discussed herein by, for example, maintaining a substantially constant height of the bottle. Inhibiting stretching of the bottle can help with applying a label to a label portion of the bottle. For example, with a label applied to a bottle, inhibiting stretching of the bottle helps retain a constant length or height of the bottle at the label panel portion, which can help prevent tearing of the label and/or prevent the label from at least partially separating from the bottle (i.e., failure of the adhesive between the bottle and the label). Further details on the features and functions of varying depth ribs are disclosed in U.S. patent application Ser. No. 13/705,040, entitled “Plastic Container with Varying Depth Ribs,” filed on Dec. 4, 2012, now U.S. Pat. No. 8,556,098, entitled “Plastic Container Having Sidewall Ribs with Varying Depth,” which claims benefit to U.S. Provisional Patent Application Ser. No. 61/567,086, entitled “Plastic Container with Varying Depth Ribs,” filed on Dec. 5, 2011, the entirety of each of which is incorporated herein by reference.
A balance may be achieved between flattened and/or shallow ribs and deep ribs to attain a desired resistance to bending, leaning, and/or stretching while maintaining stiffness in a lightweight bottle. In some embodiments, at least some of the aforementioned desired qualities may be further achieved through a steeper bell portion of a bottle. A steeper bell portion can increase top load performance in a lightweight bell. A lightweight bottle body and bell leaves more resin for a thicker base of the bottle, which can increase stability. A thicker base may better resist bending and top load forces and benefits designs with a larger base diameter with respect to the bottle diameter for tolerance even when the base is damaged during packaging, shipping, and/or handling.
Embodiments disclosed herein have a base rib that can function as a strap from a base to a sidewall of the bottle to the help further achieve resistance to bending, leaning, stretching and/or flexing while maintaining stiffness. A strap rib on a base helps the base resist deformation under pressure without necessitating the base being overly heavy in weight relative to the lightweight bottle (i.e., relative to wall thickness of flat foot base that does not resist pressure as well). The strap base rib can be incorporated into a flat foot base. A flat foot base helps retain base foot thickness. Retaining base foot thickness helps retain bottle integrity during packaging and handling using lightweight packaging, such as, for example, film only packaging that requires the base to directly resist forces, including bending and point loading, during packaging, shipping, and/or handling. A flat foot base performs well with or without internal pressure due to, for example, the ability to maintain relative foot thickness in the base in a lightweight bottle. Without strap ribs, the base may have little internal pressure resistance and may rollout (pop out and create a rocker bottom). The strapped base rib helps resist damage and deformation as discussed herein without requiring a relatively heavy footed base. Without requiring a relatively heavy footed base, less material is needed for the lightweight bottle. Further, the strapped base design may allow for a relatively easier blowing process than other known pressure bases. Thus, a base with a strap rib as disclosed herein provides for a material efficient, pressure optional bottle base.
Incorporating a strap base rib into the base with column formations in the sidewall of the bottle as discussed herein offers pressure resistance for internally pressurized bottles while maintaining strength and performance (i.e., resistance to bending and leaning) when without internal pressure (i.e., pressure release by a user opening a closure of a bottle). The strap base rib can act with the column formation on the sidewall of the bottle to form straps around the bottle to communicate stresses along the height of the bottle.
The base with a strap base rib helps maintain strength and performance of the column formations for internally pressurized bottles. With a strap base rib, the resistance to bending, leaning, and/or stretching while maintaining stiffness and hoop strength is maintained without pressure while enhancing these characteristics when the bottle is pressurized. For example, a strap base rib allows the utilization of a flat foot base for better base strength during processing at a plant (i.e., adding beverage contents), while preventing rollout or popping out of the base during pressurization. Rollout of the base bottle leads to what may be called a “rocker bottom.” Preventing rollout of the base helps the bottle stay level when resting on a surface and maintains the flat feet as the contact points on the surface. Further, base rollout can also occur without pressurization or low pressurization of the bottle, such as, for example, during shipping and handling or filling at high speed. A strap base rib also helps prevent base rollout without or low internal pressurization. While the specification herein may discuss preventing or inhibiting deformation under external/internal pressures and/or forces, it is to be understood that some deformation of a bottle may occur without straying outside of the scope of this disclosure. Some deformation of the bottle under external/internal pressures and/or forces may occur while retaining excellent structural properties of the features and functions disclosed herein.
Embodiments disclosed herein can be utilized for bottle pressures of a wide range. The strap base rib can help resist pressurization pressures in the bottle of up to 3 bars, including up to 2.5, up to 2, up to 1.5, up to 1, up to 0.5 bars, and up to 0.3 bars, including ranges bordered and including the foregoing values. The preform design also plays a role in resisting pressures such that much higher pressures than already demonstrated can be resisted with greater strap thickness available from the preform. The strap design provides a more efficient way of resisting the pressure in a bottle that also performs well without pressure.
Embodiments disclosed herein can be utilized in bottle volumes of a wide range. For example, features and functions disclosed herein can be utilized with a 3 ounce bottle up to a multiple gallon bottle. As another example, features and functions disclosed herein can be utilized with an 8 ounce (0.24 liter/0.15 liter) bottle up to a 3 liter bottle, including 12 ounces (0.35 liters) to 2 liters, 16 (0.47 liters) ounces to 1 liter, 18 ounces (0.53 liters) to 0.75 liters, and 0.5 liters, including ranges bordered and including the foregoing values.

Referring to
A substantially vertical wall comprising the grip portion 8 and label portion 10 between the base 24a and bell 16, extending substantially along the central axis 25 to define at least part of the interior of the bottle 1, can be considered a sidewall of the bottle 1. In some embodiments, the sidewall may include the bell 16, shoulder 18, and/or base 24a. The perimeter (i.e., periphery) of the sidewall is substantially perpendicular to the central axis 25 of the interior. The sidewall defines at least part of the interior of the bottle 1. The finish 12, the neck 14, the bell 16, the shoulder 18, the label portion 10, the grip portion 8, and the base 24a can each define a respective perimeter or circumference (i.e., periphery) (substantially perpendicular to the central axis 25) corresponding to that portion. For example, the label portion 10 has a label portion perimeter. As another example, the grip portion 8 has a grip portion perimeter.
In the embodiment illustrated in
In some embodiments, the flattened and/or shallow ribs 6b of the label panel ribs 20a are vertically misaligned with the flattened and/or shallow ribs 6a of the grip portion ribs 3a such that the label portion 10 has a set of recessed columns and the grip portion 8 has another set of recessed columns. Thus, the recessed column of the label portion 10 can be vertically misaligned from the recessed columns of the grip portion 8. In some embodiments, the bottle 1 can have recessed columns in just the grip portion 8 or just the label panel portion 10.
In the illustrated embodiments with three lined-up flattened and/or shallow ribs 6a,b, the bottle respectively has three recessed columns 7a. The three recessed columns 7a may be equally spaced apart around the circumference of the bottle 1 and located on the opposite side of the bottle circumference from the deep rib 2a,b portions. With three equally spaced recessed columns 7a, the recessed columns 7a are spaced every 120 degrees around the bottle 1 circumference. Any number of recessed columns 7a may be incorporated into a design of the bottle 1 by increasing or decreasing the number of flattened and/or shallow ribs 6a,b that substantially vertically line up along the vertical or central axis 25. For instance, the bottle may have as few as 1 or up to 10 recessed columns 7a, including 2, 3, 4, 5, 6, 7, 8, or 9 recessed columns 7a, including ranges bordered and including the foregoing values. The collections of flattened and/or shallow ribs 6a,b that form recessed columns 7a provide resistance to leaning, load crushing, and/or stretching. Leaning can occur when during and/or after bottle packaging, a bottle experiences top load forces (tangential forces or otherwise) from other bottles and/or other objects stacked on top of the bottle. Similarly, top load crushing can occur due to vertical compression (or otherwise) forces from bottles and/or other objects stacked on top. Stretching can occur when a bottle is pressurized. The recessed columns 7a transfer the resulting forces along the wall to the base 24a and increase bottle 1 rigidity. Deep ribs 2a,b of the grip portion ribs 3 a and label panel ribs 20a provide the hoop strength that can be equivalent to the hoop strength of normal or non-varying depth ribs. The number of ribs, including base ribs 22, grip portion ribs 3a, and/or label panel ribs 20a may vary from 1 to 30 ribs every 10 centimeters of any rib containing portion of the bottle, such as, but not limited to the grip portion 8 and/or label panel portion 10, including 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, or 29 ribs every 10 centimeters, including ranges bordered and including the foregoing values. The aforementioned 10 centimeter section that is used to measure the number of ribs need not be actually 10 centimeters in length. Rather, 10 centimeters is used illustratively to provide a ratio for the number of ribs.
While discussed above in reference to
With continued reference to
The strap rib 40a is relatively larger and deeper than the load rib 44a as discussed herein. As illustrated in
The strap rib 40a can extend substantially from a central portion of the base 24a (from the central axis 25) as discussed herein. The strap rib 40a can act as a strap between the recessed columns 7a of the sidewall to the central portion of the base 24a. As shown in
As shown in
The strap rib 40a has a base end 56a that terminates near, at, or in the dome 54. In some embodiments, the base end 56a for a strap rib 40a can be positioned outside of the dome 54 region similarly to base ends 58a for load ribs 44a. The strap rib 40a has a petal wall (i.e., valley wall) 48a that connects that strap rib 40a to portions of the base 24a and the feet 45a of the base 24a. The petal wall 48a smoothly and gradually transitions into the base 24a and the feet 45a. The smooth and gradual transition provides internal pressure resistance at and near the petal wall 48a since more spherical features of the bottle 1 can better accommodate internal pressure. The strap rib 40a is relatively deeper in the base 24a than the load rib 58a to provide stress transfer and pressure resistance as discussed herein.
The load rib 44a has a base end 58a that terminates at, near, or at the dome 54. As shown in
The sharper transitions provide for faster transitions into the feet 45a of the base 24a. Faster transitions lead to more area of the base 24a being available for relatively larger feet 45a. Larger feet 45a of a flat foot base 24a as discussed herein and as illustrated in
As shown in

Referring to
In the illustrated embodiment with three lined-up flattened and/or shallow rib 6a portion, the bottle 1 respectively has three recessed columns 7a. The three recessed columns 7a are equally spaced apart around the circumference of the bottle and located on the opposite side of the bottle circumference from the deep rib 2a portions. However, the flattened and/or shallow ribs 6a may be unequally spaced apart around the circumference of the bottle 1. Further, any number of recessed columns 7a may be incorporated into a design of the bottle 1 by increasing or decreasing the number of flattened and/or shallow ribs 6a that substantially vertically line up along the vertical or central axis 25. For instance, the bottle may have as few as 1 or up to 10 recessed columns 7a, including 2, 3, 4, 5, 6, 7, 8, or 9 recessed columns 7, including ranges bordered and including the foregoing values. In the illustrated embodiment, the collections of flattened and/or shallow ribs 6a that form recessed columns 7a provide resistance to leaning, and/or load crushing, and/or stretching. Leaning can occur when during and/or after bottle packaging, a bottle experiences top load forces (tangential forces or otherwise) from other bottles and/or other objects stacked on top of the bottle. Similarly, top load crushing can occur due to vertical compression (or otherwise) forces from bottles and/or other objects stacked on top. Stretching can occur when a bottle is pressurized. In the illustrated embodiment, the recessed columns 7a transfer the resulting tangential or compression forces along the wall to the base 24a and increase bottle 1 rigidity. Deep ribs 2a of the grip label rib 3 a provide the hoop strength that can be equivalent to the hoop strength of normal depth ribs. As with the flattened and/or shallow rib 6a portions, the deep rib 2a portions may vary from 1 to 10 in number on the grip panel ribs 3a, including 2, 3, 4, 5, 6, 7, 8, or 9 deep rib 2 portions, including ranges bordered and including the foregoing values.

Referring to
In the illustrated embodiment, with three lined-up flattened and/or shallow rib 6b portions, the bottle 1 respectively has three recessed columns 7a. The flattened and/or shallow ribs 6b of the label panel ribs 20a can vertically line up along the vertical or central axis 25 with the flattened and/or shallow ribs 6a of the grip portion ribs 3a to form the three recessed columns 7a. Thus, in some embodiments, the recessed columns 7a can extend along a majority or substantial entirety of the sidewall (e.g., height and/or length) of the bottle 1 as, for example, illustrated in
In some embodiments, the flattened and/or shallow ribs 6b of the label panel ribs 20a are vertically misaligned with the flattened and/or shallow ribs 6a of the grip portion ribs 3a such that the label portion 10 has a set of recessed columns and the grip portion 8 has another set of recessed columns. Thus, the recessed column of the label portion 10 can be vertically misaligned from the recessed columns of the grip portion 8.
The plurality of deep ribs 2b of the label portion 10 can substantially vertically line up along the vertical or central axis 25 with the plurality of deep ribs 2a of the grip portion 8 as illustrated in
In the illustrated embodiment, the three recessed columns 7a are equally spaced apart around the circumference of the bottle and located on the opposite side of the bottle circumference from the deep rib 2b portions. However, the flattened and/or shallow ribs 6a,b may be unequally spaced apart around the circumference of the bottle 1. Further, any number of recessed columns 7a may be incorporated into a design of the bottle 1 by increasing or decreasing the number of flattened and/or shallow ribs 6a,b that substantially vertically line up along the vertical or central axis 25. For instance, the bottle 1 may have as few as 1 or up to 10 recessed columns 7a, including 2, 3, 4, 5, 6, 7, 8, or 9 recessed columns 7a, including ranges bordered and including the foregoing values. In the illustrated embodiment, the collections of flattened and/or shallow ribs 6b that form recessed columns 7a provide resistance to leaning, load crushing, and/or stretching as discussed herein. In the illustrated embodiment, the recessed columns 7a transfer the resulting tangential or compression forces along the wall to the base 24a and increase bottle 1 rigidity. Deep ribs 2b of the label panel rib 20a provide the hoop strength that can be equivalent to the hoop strength of normal depth ribs. As with the flattened and/or shallow rib 6b portions, the deep rib 2b portions may vary from 1 to 10 in number on the label panel rib 20a, including 2, 3, 4, 5, 6, 7, 8, or 9 deep rib 2b portions, including ranges bordered and including the foregoing values.

The strap rib 40a extends from the base end 56a to the sidewall end 42a along one or more radii. As shown in
In some embodiments, the radius Rla and/or radius R2a are relatively large or infinite. Stated differently, the strap rib 40a can be straight or nearly straight from the base end 56a to the sidewall end 42a. A straight strap rib can resist more pressure. Providing a curvature with one or more radii to the strap rib can improve the blowing process to help prevent poorly blown bottles, which may reduce pressure resistance. In some embodiments, the strap rib 40a is a combination of curved and straight portions, such as, for example, as discussed in reference to
In some embodiments, the transition 41a from radius Ria to radius R2a (or more than one transition with a strap rib having more than two radii) can occur anywhere along the strap rib 40a. As show in
The strap rib 40b extends from the base end 56b to the sidewall end 42b along one or more radii. As shown in
In some embodiments, the radius Rib and/or radius R2b are relatively large or infinite. Stated differently, the strap rib 40b can be straight or nearly straight from the base end 56b to the sidewall end 42b. A straight strap rib can resist more pressure. Providing a curvature with one or more radii to the strap rib can improve the blowing process to help prevent poorly blown bottles, which may reduce pressure resistance. In some embodiments, the strap rib 40b has more than one straight portion 45 as discussed herein positioned anywhere along the strap rib 40b from the base sidewall end 42b to the base end 56b. The straight portions 45 can be positioned to connect with curved portions and/or other straight portions of the strap rib 40b. The straight portions 45 can be any length, including substantially an entire length of the strap rib 40b from the sidewall end 42b to the base end 56b.
In some embodiments, the transition 41b from radius Rib to radius R2b (or more than one transition with a strap rib having more than two radii) can occur anywhere along the strap rib 40b. As shown in
In some embodiments, the transition 43b from radius R2b (or Rib in some embodiments) to the straight portion 45 can occur anywhere along the strap rib 40b. As shown in
Referring to
A substantially vertical wall (or sidewall) comprising the grip portion 8 and label portion 10 between the base 24e and the bell 16, extending substantially along the central axis 25 to define at least part of the interior of the bottle 3, can be considered a sidewall of the bottle 3. In some embodiments, the sidewall may include the bell 16, shoulder 18, and/or base 24e. The perimeter of the sidewall is substantially perpendicular to the central axis 25 of the interior. The sidewall defines at least part of the interior of the bottle 3. The finish 12, the neck 14, the bell 16, the shoulder 18, the label portion 10, the grip portion 8, and the base 24e can each define a respective perimeter or circumference (substantially perpendicular to the central axis 25) corresponding to that portion. For example, the label portion 10 has a label portion perimeter. As another example, the grip portion 8 has a grip portion perimeter.
In the embodiment illustrated in
In some embodiments, the flattened and/or shallow ribs 6d of the label panel ribs 20b are vertically misaligned with the flattened and/or shallow ribs 6a of the grip portion ribs 3b such that the label portion 10 has a set of recessed columns and the grip portion 8 has another set of recessed columns. Thus, the recessed column of the label portion 10 can be vertically misaligned from the recessed columns of the grip portion 8. In some embodiments, the bottle 3 can have recessed columns in just the grip portion 8 or just the label panel portion 10.
In the illustrated embodiment with four lined-up flattened and/or shallow ribs 6a,b, the bottle respectively has four recessed columns 7c on each flat wall of the square bottle. The four recessed columns 7c may be equally spaced apart around the perimeter of the bottle 3 and located on the opposite sides of the bottle 3 with respect to each other. With four equally spaced recessed columns 7c, the recessed columns 7c are spaced every 90 degrees around the bottle 3 perimeter. The four recessed columns 7c are positioned on the flat portions of the sidewalls of the bottle 3. Any number of recessed columns 7c may be incorporated into a design of the bottle 3 by increasing or decreasing the number of flattened and/or shallow ribs 6c,d that substantially vertically line up along the vertical or central axis 25. For instance, the bottle may have as few as 1 or up to 10 recessed columns 7c, including 2, 3, 4, 5, 6, 7, 8, or 9 recessed columns 7c, including ranges bordered and including the foregoing values. The collections of flattened and/or shallow ribs 6c,d that form recessed columns 7c provide resistance to leaning, load crushing, and/or stretching as discussed herein. The recessed columns 7c transfer the resulting tangential or compression forces along the wall to the base 24e and increase bottle 3 rigidity.
The shape of the square bottle adds hoop strength to the bottle 3 by having four corners. The deep ribs 2c,d of the grip portion ribs 3b and label panel ribs 20b can complement the hoop strength by providing additional hoop strength. As shown in
The number of ribs, including base ribs 22, grip portion ribs 3b, and/or label panel ribs 20b may vary from 1 to 30 ribs every 10 centimeters of any rib containing portion of the bottle, such as, but not limited to the grip portion 8 and/or label panel portion 10, including 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, or 29 ribs every 10 centimeters, including ranges bordered and including the foregoing values. The aforementioned 10 centimeter section that is used to measure the number of ribs need not be actually 10 centimeters in length. Rather, 10 centimeters is used illustratively to provide a ratio for the number of ribs.
The strap rib 40e is relatively larger and deeper than the strap rib 44e as discussed herein. As illustrated in
The sidewall end 42e of the strap rib 40e vertically aligns or points to substantially the center of the recessed columns 7c (center point of the shallow and/or flattened ribs 2c,d). As illustrated in
The load rib 44e has a base end 58e that terminates at near or at the dome 54. As shown in
The sharper transitions provide for faster transitions into the feet 45e of the base 24e. Faster transitions lead to more area of the base 24e being available for relatively larger feet 45e. Larger feet 45e of a flat foot base 24e as discussed herein and as illustrated in

It is contemplated that various combinations or subcombinations of the specific features and aspects of the embodiments disclosed above may be made and still fall within one or more of the inventions. Further, the disclosure herein of any particular feature, aspect, method, property, characteristic, quality, attribute, element, or the like in connection with an embodiment can be used in all other embodiments set forth herein. Accordingly, it should be understood that various features and aspects of the disclosed embodiments can be combined with or substituted for one another in order to form varying modes of the disclosed inventions. Thus, it is intended that the scope of the present inventions herein disclosed should not be limited by the particular disclosed embodiments described above. Moreover, while the invention is susceptible to various modifications, and alternative forms, specific examples thereof have been shown in the drawings and are herein described in detail. It should be understood, however, that the invention is not to be limited to the particular forms or methods disclosed, but to the contrary, the invention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the various embodiments described and the appended claims. Any methods disclosed herein need not be performed in the order recited. The methods disclosed herein include certain actions taken by a practitioner; however, they can also include any third-party instruction of those actions, either expressly or by implication. For example, actions such as “passing a suspension line through the base of the tongue” include “instructing the passing of a suspension line through the base of the tongue.” It is to be understood that such depicted architectures are merely examples, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. The ranges disclosed herein also encompass any and all overlap, sub-ranges, and combinations thereof. Language such as “up to,” “at least,” “greater than,” “less than,” “between,” and the like includes the number recited. Numbers preceded by a term such as “approximately”, “about”, and “substantially” as used herein include the recited numbers, and also represent an amount close to the stated amount that still performs a desired function or achieves a desired result. For example, the terms “approximately”, “about”, and “substantially” may refer to an amount that is within less than 10% of, within less than 5% of, within less than 1% of, within less than 0.1% of, and within less than 0.01% of the stated amount.
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced embodiment recitation is intended, such an intent will be explicitly recited in the embodiment, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following disclosure may contain usage of the introductory phrases “at least one” and “one or more” to introduce embodiment recitations. However, the use of such phrases should not be construed to imply that the introduction of an embodiment recitation by the indefinite articles “a” or “an” limits any particular embodiment containing such introduced embodiment recitation to embodiments containing only one such recitation, even when the same embodiment includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”), the same holds true for the use of definite articles used to introduce embodiment recitations. In addition, even if a specific number of an introduced embodiment recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C” or “one of the A, B, or C,” etc. is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C (or one of the A, B, or C)” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, embodiments, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting.
