Definitions

  • the present disclosure generally relates to containers. More specifically, the present disclosure relates to lightweight containers having improved vacuum resistance capacities and improved aesthetics.
  • the market comprises many different shapes and sizes of containers capable of housing fluids.
  • the shape and size of fluid containers can depend, among other things, on the amount of fluid to be housed, the type of fluid to be housed, consumer demands and desired aesthetics.
  • toxic fluids may be required to be housed in containers that have thicker walls and a more rigid structure.
  • the market for these types of fluids is determined by safety of the containers more so than that container's aesthetics.
  • consumable fluids such as water may be housed in containers that generally have thinner walls and a less rigid structure.
  • the market for consumable fluids may be determined by the aesthetics desired by the consumer instead of safety requirements.
  • the container should be able to withstand different environmental factors encountered during, for example, manufacturing, shipping and retail shelf stocking or storage.
  • One example of such an environmental factor includes oxygen absorption into the product housed in the container.
  • certain liquid consumer products are susceptible to absorption of oxygen that is present in the headspace of the container and/or oxygen that ingresses from the outside environment. This oxygen absorption can create a vacuum inside the container that can attribute to deformation of the bottle, resulting in poor overall aesthetics. Accordingly, a need exists for a lightweight fluid container having improved structural features as well as desirable aesthetic characteristics.
  • the present disclosure relates to lightweight, vacuum-resistant containers for housing liquid products.
  • the present disclosure provides a container including a body having at least first and second interrupted, horizontal ribs.
  • the first interrupted, horizontal rib may be located in a horizontal plane that is different from the horizontal plane occupied by the second, interrupted, horizontal rib.

  • An advantage of the present disclosure is to provide an improved container.
  • Another advantage of the present disclosure is to provide a lightweight container that resists vacuum deformation.
  • Still another advantage of the present disclosure is to provide a container having improved vacuum-resistance features.
  • Yet another advantage of the present disclosure is to provide a container having improved aesthetics.
  • Another advantage of the present disclosure is to provide a container that is constructed and arranged for easy handling by a consumer.
  • Figure 1 shows a perspective view of a container in an embodiment of the present disclosure.
  • Figure 2 shows a side view of a container in an embodiment of the present disclosure.
  • the present disclosure relates to lightweight, vacuum-resistant bottles and/or containers for providing consumable products and other fluids.
  • the bottles are constructed and arranged to be vacuum resistant to provide a lightweight bottle having not only improved structural features, but also improved aesthetics.
  • liquid consumable products are oxygen sensitive. This becomes increasing relevant, for example, when the liquid consumable products are shelf-stable and may spend an amount of time sitting on a retail shelf.
  • oxygen may be absorbed by the product from the headspace in the container or from the outside environment that permeates through the container walls. Such oxygen absorption can induce a vacuum inside the bottle that causes the bottle to deform.
  • bottles can be exposed to widely varying temperature and pressure changes (e.g., bottle contraction in the refrigerator), liquid losses, and external forces that jostle and shake the bottle.
  • the bottles contain carbonated fluids
  • these types of environmental factors can contribute to internal pressures or vacuums that affect the overall quality of the product purchased by the consumer.
  • existing types of vacuum panels, or thin plastic labels can occupy large areas of the exterior of the bottle to which they are added and tend to have great visual impacts.
  • the shrink sleeve labels do not always follow the slightly inverted shape of the bottle created by the vacuum, thereby accounting for poor aesthetics of the bottle.
  • Applicants do not believe that any product currently exists on the market that provides a lightweight plastic container (e.g., polyethylene terepthalate) having an improved product sleeve appearance as a result of increased vacuum resistance from modified ribs or indentations in the container.
  • a lightweight plastic container e.g., polyethylene terepthalate
  • containers with fully circumferential, horizontal ribs must increase the rib dimensions to create a lightweight container.
  • the ribs are more visible to the consumer, which provides for less than optimal aesthetic properties.
  • providing panels on the containers provides a more visually appealing container, but require more plastic material, which creates a heavier container.
  • containers of the present disclosure include features that help to avoid bottle deformation that would cause loss of stability of the container and the potential perception of the consumer that the container has a defect and is not suitable for purchase.
  • containers of the present disclosure may include horizontal ribs, or indentations, having increased dimensions that are more visible and have a greater impact on the visual appearance of any thin films (e.g., container sleeves) applied to the container. Increasing the horizontal rib dimensions almost doubles the straight surface of a container, thereby providing a greater surface area for contacting any sleeves applied to the container, and improving vacuum resistance within the container.
  • the ribs of the present disclosure may also be interrupted, located in different horizontal planes, and offset with respect to each other along a vertical line extending along a body of the containers.
  • containers of the present disclosure may be used to house carbonated liquids, or may be exposed to temperature and/or pressure changes during packaging, shipping, storage and/or retail display.
  • Any of the above- described factors e.g., carbonation, temperature changes, pressure changes, etc.
  • carbonation, temperature changes, pressure changes, etc. can contribute to the presence of an internal vacuum within a sealed container when the container houses a liquid. This is problematic for aesthetic reasons because internal vacuums created within the sealed container can cause deformation of the container that can pull the walls of the container away from any exterior label (e.g., sleeve), creating an undesirable aesthetic.
  • Applicants have surprisingly found, however, that certain structural features can help to improve a container's vacuum resistance to avoid undesired container deformation.
  • a container “sleeve” is a thin, plastic film that may include indicia thereon and is typically used in the marketplace for product identification and for displaying product information.
  • the present disclosure provides a container, or bottle, 10 having a mouth 12, a neck 14, a shoulder 16, a body 18, and a base 20.

  • Shoulder 16 has a lopped-off apex since shoulder 16 tapers into neck 14 for functionality of container 10.
  • the "square pyramid frustum" shape also includes rounded edges 28 between triangular faces 26, and rounded edges 30 between each triangular face 26 and the imaginary square base, as will be discussed further below.

In an embodiment, inward-directed slopes have an angle of about 15°. Accordingly, as the height of container 10 increase or decreases, either or both of the length and width of body 18 may change as well. Such a configuration provides the added benefit of ease of handling for the consumer.
  • the two mirror- image, inward-directed sloped portions 34, 36 of body 18 meet at a tapered portion of body 18 that helps consumer to grip container 10 for ease of handling.

  • body 18 may also include any number of interrupted side ribs 40 located on a side 42 of container 10.
  • Side ribs 40 are described as "interrupted” because they do not extend all the way around container 10 but are, instead, interrupted around container 10.
  • Body 18 may have any number of interrupted side ribs 40 ranging, for example, from about 1 to about 10, or 2, 3, 4, 5, 6, 7, 8, 9, or the like.

Corner ribs 44 are similarly described as “interrupted” because they do not extend all the way around container 10 but are, instead, interrupted around container 10. Body 18 may have any number of interrupted corner ribs 44 ranging, for example, from about 1 to about 10, or 2, 3, 4, 5, 6, 7, 8, 9, or the like. Each corner rib 44 is supported on its ends by the sides 42 of body 18, forming a bridge across body 18. By interrupting corner ribs 44 at the sides 42 of body 18, limited visual impact can be attained for any applied labels or shrink sleeves.

  • interrupted side ribs 40 are in different horizontal planes than interrupted corner ribs 44 and only slightly overlap along a vertical line 46 extending along body 18. Accordingly, since interrupted side ribs 40 and interrupted corner ribs 44 are in different horizontal planes and do not substantially overlap along a vertical portion of body 18, interrupted side ribs 40 and interrupted corner ribs 44 are offset from each other.
  • interrupted side ribs 40 are in different horizontal planes but substantially overlap along a vertical portion of body 18 (e.g., 100% overlap in the vertical direction such that each interrupted side rib 40 lines up with every other interrupted side rib 40 on the same side of the container). Accordingly, interrupted side ribs 40 are not offset from each other. Offset ribs should not overlap in a vertical direction by more than about 50%, or more than about 40%, or more than about 30%, or more than about 20%, or more than about 10%, or more than about 5% of a perimeter (e.g, circumference, outer surface measurement, etc.) of container 10.
