  • Beverage containers for storing various types of beverages may be composed of a plastic material, such as polyethylene terephthalate (PET), among others.
  • PET polyethylene terephthalate
  • Such plastic beverage containers often have a generally cylindrical construction.
  • Plastic beverage containers may be filled with a beverage via a hot-filling operation.
  • a beverage to be stored in the beverage container is heated to an elevated temperature, such as a temperature of about 170°F or more, and deposited in the beverage container.
  • the beverage container may be supported on a support surface during filling, or the beverage container may be suspended by an upper end, or neck, of the beverage container during filling. Once filled and capped, the beverage container and beverage therein are rapidly cooled.
  • This cooling of the beverage may result in thermal contraction, which reduces the internal volume of the beverage container.
  • side walls of the beverage container may be pulled inward.
  • this can result in undesirable deformation, or “paneling” of the side wall, where a once-cylindrical sidewall takes on flattened or otherwise deformed shapes in order to accommodate the internal vacuum created by the reduction in volume of the beverage due to thermal contraction during cooling.
  • one or more ribs may be formed in the beverage container.
  • the ribs may be formed on the beverage container as recessed (indented) channels that extend toward an interior volume of the beverage container and extend completely around the circumference of the beverage container in a plane transverse to a longitudinal axis of the beverage container.
  • the ribs help to prevent the beverage container from paneling or otherwise deforming when an internal pressure of the beverage container is less than an external pressure. Such paneling may reduce the structural stability of the beverage container. Also, beverage containers that experience deformation may be unappealing to consumers, which may negatively impact sales of the beverage containers. While the ribs extending around a circumference of the beverage container may help to avoid paneling, the ribs may make the beverage container more susceptible to elongation in a longitudinal direction during certain types of filling operations.
  • the plastic may begin to deform if heated to a sufficiently high temperature, such as a temperature at or above the glass transition temperature of the beverage container.
  • a sufficiently high temperature such as a temperature at or above the glass transition temperature of the beverage container.
  • the weight of the beverage within the container and the heat may cause the beverage container to elongate in a longitudinal direction.
  • elongation may be most significant at the ribs of the beverage container, as the ribs may stretch or flatten, resulting in elongation of the beverage container.
  • Elongation of the beverage container may be undesirable because the elongation may result in beverage containers having different heights.
  • Beverage containers having various heights may make it difficult to stack and store the beverage containers.
  • a case of beverage containers having varying heights may not evenly carry the load of another case of beverage containers stacked atop the first.
  • the taller beverage containers may carry more of the load than the shorter ones, and may apply uneven pressure to the second case. This may make the second case sit unevenly on the first, making stacking and storage more difficult. This problem may compound as additional cases of beverage containers are stacked on top of one another.
  • a beverage container includes a sidewall with a channel formed in the sidewall having a sinusoidal shape that extends around a circumference of the beverage container.
  • the channel helps to resist elongation of the beverage container, such as during hot-filling operations, while also providing resistance to paneling.
  • the sidewall of the beverage container may further include linear channel segments that extend along a portion of a circumference of the sidewall. The linear channel segments may provide further resistance to paneling.
  • a beverage container 100 includes a base 120, a sidewall 160 extending from and integrally formed with base 120, and an upper region 180 extending from and integrally formed with sidewall 160 and defining an upper opening.
  • Beverage container 100 may include a recessed region 190 where sidewall 160 transitions to upper region 180.
  • Beverage container 100 includes a longitudinal axis Z extending centrally in a direction from base 120 to upper region 180.
  • Sidewall 160 is generally cylindrical such that beverage container 100 has a generally circular transverse cross section (not accounting for channels formed in sidewall 160).
  • sidewall 160 of beverage container 100 may include one or more circumferential channels 150 extending continuously around a circumference of sidewall 160.
  • one circumferential channel 150 is arranged at lower end 162 of sidewall 160 adjacent base 120.
  • circumferential channel 150 may help to provide sidewall 160 with hoop strength and resistance to paneling but may be susceptible to elongation.
  • one or more channels 140 are formed in sidewall 160 that serve to prevent or limit elongation of beverage container 100 in a direction of the longitudinal axis Z.
  • Channels 140 are formed as recessed areas in sidewall 160 that extend toward an interior volume of beverage container 100.
  • Channels 140 also serve to resist paneling of sidewall 160 (e.g., when an internal pressure of beverage container 100 is less than an external pressure) by contributing hoop strength to beverage container 100.
  • beverage container 100 is configured to resist elongation in a direction of longitudinal axis Z when beverage container 100 is suspended from upper region 180 and is filled with a beverage having a temperature at or above a glass transition temperature of the material forming beverage container 100 (e.g., PET).
  • a continuous channel 140 is formed in sidewall 160 and extends around a circumference C of sidewall 160.
  • continuous channel 140 has a sinusoidal shape such that continuous channel 140 includes a series of alternating peaks 146 and troughs 144 separated by diagonal regions 142.
  • Diagonal regions 142 may be generally linear or may have a slight curvature so as to be curvilinear. It is understood that diagonal regions 142 may necessarily have a slight curvature as diagonal regions 142 extend around a portion of cylindrical sidewall 160. Further, in some embodiments, diagonal region 142 may have a slight curvature as a diagonal region 142 approaches a peak 146 or a trough 144.
  • continuous channel 140 may form three peaks 146 (and thus three troughs 144). Some embodiments may include additional or fewer peaks 146, however, due to approach and passage through a transverse plane relative to longitudinal axis Z, peaks 146 and troughs 144 may be more susceptible to elongation than diagonal regions 142 of continuous channel 140. As a result, the susceptibility of beverage container 100 to elongation decreases as the number of peaks 146 (and troughs 144) is reduced.
  • Continuous channels 140 serve a dual purpose: to resist or prevent elongation of beverage container 100 in a direction of longitudinal axis Z during hot-filling operations, and to resist or prevent paneling of beverage container 100 when an internal pressure of beverage container 100 is less than an external pressure.
  • ribs (or channels) that extend circumferentially around the beverage container and that are oriented in or near a plane transverse to a longitudinal axis Z may be susceptible to elongation in the direction of longitudinal axis Z, because, for example, the weight of a high-temperature beverage will be directed in the direction of longitudinal axis Z, nearly perpendicularly to the ribs.
  • diagonal regions 142 of continuous channel 140 are less susceptible to elongation because diagonal regions 142 are oriented at an angle relative to a transverse plane.
  • beverage container 100 is less able to stretch longitudinally in diagonal region 142 of continuous channel 140.
  • the weight of the high-temperature beverage (in the direction of longitudinal axis Z) will not be perpendicular to the direction of diagonal region 142 and will instead be at an angle thereto.
  • continuous channels 140 extend around a circumference C of sidewall
  • continuous channels 140 inhibit sidewall 160 from deforming, such as collapsing toward an interior of beverage container 100 when an internal pressure of beverage container 100 is greater than an external pressure.
  • continuous channels 140 also help sidewall 160 to maintain a cylindrical configuration.
  • diagonal regions 142 of continuous channel 140 are formed at an angle Oi, relative to a plane that is transverse to longitudinal axis Z of beverage container 100.
  • angle Oi may be, for example, 40 to 50 degrees.
  • the angle may be 45 degrees so as to balance resistance to paneling when beverage container 100 is subjected to a pressure differential and resistance to elongation during hot-filling operations.
  • angle Oi decreases, such that continuous channel 140 is flattened and the sinusoidal pattern has a lower amplitude, the resistance to elongation provided by continuous channel 140 decreases while resistance to paneling increases.
  • channels 140 have a rounded indented surface, as shown for example at FIG. 3.
  • Continuous channels 140 may take the form of a circular arc (e.g., a semi-circle) in cross section.
  • channels 140 may have other cross-sectional shapes, for example a U-shape or parabolic cross-sectional shape, among others.
  • continuous channels 140 may have a width w as measured in a transverse direction of a channel 140 from a first side 141 to an opposing second side 143 of channel 140. Width w may be, for example, 4 mm to 8 mm.
  • continuous channels 140 may have a depth d as measured from a plane of sidewall 160 to a deepest portion of channel 140.
  • Depth d may be, for example, 0.5 mm to 4 mm (e.g., 0.8 mm).
  • continuous channels 140 have a circular-arc cross section based on a circle of 4 mm to 8 mm (e.g., 6 mm) diameter, with a depth d of 0.5 mm to 4 mm (e.g., 0.8 mm). As depth d of continuous channel 140 increases, the resistance of beverage container 100 to paneling increases. However, increasing depth d of channel 140 may make beverage container 100 more susceptible to elongation in a longitudinal direction. In some embodiments, all continuous channels 140 have the same cross- sectional size and shape.
  • sidewall 160 is formed with two or more continuous channels 140a, 140b, such as a lower continuous channel 140a and an upper continuous channel 140b, as shown in FIG. 2. Lower continuous channel 140a and upper continuous channel 140b are spaced from one another in a longitudinal direction. In some embodiments, sidewall 160 may include three or more continuous channels 140.
  • lower and upper continuous channels 140a, 140b may be formed with the same shape and dimensions.
  • each channel 140a, 140b may be sinusoidal.

  • each continuous channel 140 includes a lower bound L and an upper bound U, as best shown in FIG. 2.

  • Lower continuous channel 140 has a height hi
  • upper continuous channel 140b has a height h2 that may be the same as hi.
  • a height, hi or h2 of each continuous channel 140 may be about 30% to about 80% of a height of sidewall 160.

  • upper bound Ui of a lower continuous channel 140a may be above lower bound L2 of an upper continuous channel 140b. In this way, continuous channels 140a, 140b are spaced closely together such that a plane transverse to longitudinal axis Z intersects at least a portion of a continuous channel 140. In some embodiments, upper bound Ui of lower continuous channel 140a may be at or below lower bound L2 of upper continuous channel 140b.
  • sidewall 160 of beverage container 100 further includes linear channel segments 170, as shown in FIG. 4.
  • Linear channel segments 170 provide additional resistance to paneling of sidewall 160 of beverage container 100 when an internal pressure of beverage container 100 is less than an external pressure by contributing hoop strength to beverage container 100.
  • linear channel segments 170 help sidewall 160 of beverage container 100 to retain its cylindrical shape throughout filling, transportation, and storage of beverage container 100.
  • Linear channel segments 170 extend around a portion of a circumference of sidewall 160. Similarly to continuous channels 140, linear channel segments 170 may be formed in sidewall 160 as recessed areas that extend towards an interior volume of beverage container 100. Linear channel segments 170 may be positioned in one or more planes, e.g., Xi, X2, X3 and X4, that are transverse to longitudinal axis Z of beverage container 100. Each transverse plane may have multiple linear channel segments 170 that are spaced from one another around the circumference of sidewall 160. In some embodiments, a plane extending transversely to longitudinal axis Z may include four linear channel segments 170 spaced around the circumference of sidewall 160. Linear channel segments 170 in a particular plane may each be the same shape and dimensions.
  • linear channel segments 170 in a first plane Xi may extend around a circumference to a greater extent than linear channel segments 170 arranged in a second plane X2, such that the linear channel segments 170 in each plane differ in length.
  • linear segments 170 in different planes e.g., plane Xi and X2, may be aligned on sidewall 160 along longitudinal axis Z.
  • Linear channel segments 170 may be formed in sidewall 160 in an area between a lower bound L and an upper bound U of a continuous channel 140, as shown in FIG. 2. Linear channel segments 170 are spaced from continuous channel 140 such that linear channel segments 170 do not intersect or overlap with continuous channel 140. Thus, linear channel segments 170 provide additional resistance to paneling in areas of sidewall 160 not occupied by continuous channels 140. As linear channel segments 170 do not extend continuously around circumference C of beverage container 100, linear channel segments 170 do not have a significant tendency to deform in the direction of longitudinal axis Z. The sidewall material that interrupts them constrains such deformation.
  • Linear channel segments 170 may have a rounded indented surface. Similar to continuous channels 140, linear channel segments 170 may take the form of a circular arc (e.g., a semi-circle) in cross-section. However, linear channel segments 170 may have other cross-sectional shapes, for example, a U-shape or parabolic cross-sectional shape, among others. Similar to the representation of continuous channel 140 shown in FIG. 3, in some embodiments, linear channel segments 170 have a width as measured in a transverse direction of a channel segment 170 from a first side to an opposing second side of channel segment 170.

As shown in FIG. 14, vacuum panel 830 may include a perimeter 832 with a first side 832A opposite a second side 832B, and with an upper end 832C opposite a lower end 832D. First and second sides 832A, 832B of vacuum panel 830 may correspond to an oval shape. However, upper and lower ends 832C, 832D may correspond to a circular shape. In this way, upper and lower ends 832C, 832D of vacuum panel 830 are shortened and are more rounded relative to a vacuum panel having an oval shape.
  • vacuum panel may direct forces toward portions 865 (circled in dotted lines for illustration) of the sidewall 860 adjacent the upper and lower ends 832C, 832D of vacuum panel 830 which may make these portions 865 more susceptible to paneling.
  • Upper and lower ends 832C, 832D following a circular shape rather than an oval shape may help to better distribute the forces to sidewall 860 and avoid directing the forces toward portions 865 of sidewall 860 adjacent upper and lower ends 832C, 832D of vacuum panel 830.
  • vacuum panel 830 may have an oval shape.
  • beverage container 800 may include vacuum panels 830 and may further include one or more linear channel segments 870 as described herein.
