Definitions

  • the present disclosure generally relates to containers. More specifically, the present disclosure relates to containers having improved vacuum resistance capacities and improved aesthetics.
  • 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 can 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 the containers' aesthetics.
  • consumable fluids such as water can be housed in containers that generally have thinner walls and a less rigid structure. Indeed, the market for consumable fluids can be determined by the aesthetics desired by the consumer instead of safety requirements.
  • a 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 consumers 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 contribute to deformation of the bottle, resulting in poor overall aesthetics.
  • the deformation of the bottle is enhanced due to the fact that the walls thickness are lower than the ones of standard bottles.
  • the present disclosure relates to vacuum-resistant containers for housing liquid products.
  • the present disclosure provides a container including a body with at least one indented rib and at least one indented panel, the at least one indented rib and the at least one indented panel being continuous around a circumference of the body.
  • the at least one indented rib and the at least one indented panel are continuous in a substantially horizontal plane.

  • 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.

  • 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.
  • a cold-fill process is a filling process used for filling liquid products such as water or carbonated drinks into containers.
  • the containers are blow molded and filled with the liquid product at room temperature in a conventional atmosphere.
  • An aseptic filling process is a filling process carried out under aseptic conditions in which a container that has already been sterilized is filled with a liquid beverage or with food.
  • a hot-fill process is a filling process that pasteurizes to neutralize the microbiological state of the product prior to being poured, in a hot state, into the bottle.
  • the bottle is then capped, turned on the side which in turn sterilizes the cap, killing unwanted organisms.
  • the bottles are rapidly cooled down by water (steam, shower, etc.) to ensure the product and vitamin integrity.
  • the hot-fill process creates vacuum after filling, which along with the high filling temperatures requires a very robust container. This process unable storing acid beverages (pH lower than 5) that will be shelf stable at ambient temperature.
  • a rib is a structural element provided on a container to strengthen it or hold it in place.
  • a panel In the frame of a container packaging, a panel is a distinct flat portion of a wall, which surface lies above or below the general level of the container or enclosed by a frame or border.
  • a standard container is a container having standard walls thickness, said walls thickness being greater than 100 ⁇ .
  • a lightweight container is a container having thin walls thickness, said wall thickness being less than 100 ⁇ thereby leading to a container weighting at least 10% less than a standard container.

  • the bottles are constructed and arranged to be vacuum resistant to provide a bottle having not only improved structural features, but also improved aesthetics.
  • 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. This effect is observed in standard plastic bottle.
  • containers of the present disclosure include features that help to avoid bottle deformation that cause loss of stability of the container and the potential perception by the consumer that the container has a defect and is not suitable for purchase.
  • containers of the present disclosure can be used to house carbonated liquids, or can 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.

Abstract

L'invention porte sur des récipients ayant une résistance au vide améliorée et des caractéristiques esthétiques. Dans un mode de réalisation général, la présente invention concerne un corps (10) comprenant au moins une arête en indentation (22) et au moins un panneau en indentation (24). La ou les arêtes en indentation et le ou les panneaux en indentation sont continus autour d'une périphérie du corps dans un plan sensiblement horizontal de façon à maintenir une pression verticale régulière du corps. En même temps, les panneaux constituent une surface sensiblement plate pour un manchon pour le récipient. L'invention est particulièrement adaptée pour des récipients de faible poids.
