Definitions

  • the present inventive concept relates to the field of packaging. More particularly, there are disclosed packages with improved features, and related methods and devices.
  • packages for beverages are manufactured in so-called portion volumes, intended to be consumed straight from the package.
  • the majority of these packages are provided as an assembly with a drinking straw in a protective envelope which is secured on the one side wall of the package.
  • the packages which may have parallelepipedic or tetrahedral configuration, are manufactured from a laminate with a core of paper or paperboard, with different layers of thermoplastics and possibly aluminum foil.
  • On the one wall of the package most often the upper or top wall, a hole has been punched out in the core layer and this hole is covered by the remaining layers of the laminate. This makes it possible to penetrate the hole with the drinking straw which accompanies the package, resulting in a drinking straw with direct access to the drink enclosed in the package.
  • a problem with assemblies as described above is that it is difficult to consume the beverage on-the-go.
  • Preparation of the package before consumption is needed, and comprises several steps; removing the protective envelope enclosing the drinking straw from the package, after which the protective envelope is opened to retrieve the drinking straw; inserting the drinking straw into the package; adjusting an end section of the drinking straw to direct the drinking straw into the mouth of the user intending to imbibe the drink.
  • several of the above mentioned steps require two hands; alternatively, in some steps, a consumer may use one hand in combination with his or her teeth. Further, contaminants from the consumer risk entering the package. Further, the insertion of the drinking straw sometimes requires extensive force, causing contents to spill out of the package. Further, the protective envelope has to be discarded by the user.
  • Another problem is that the drinking straw may be separated from the package during production or transport, thus forcing the package, including the drink enclosed, to be discarded. Even worse, the problem of the missing drinking straw may not be discovered until the consumer intends to open the package.
  • a package for a liquid food product comprises a container having a default shape.
  • the container is designed to change its shape as a result of a difference between an external pressure and an internal pressure, and to strive towards returning to the default shape.
  • the package further comprises a hollow body attached to the container.
  • the hollow body covers a weakened portion of the container.
  • the hollow body comprises a cutting member arranged at the weakened portion, such that a hole in the container can be made with the cutting member and liquid held in the container can be transferred out from the container through the hole into the hollow body.
  • the hollow body may comprise a first piece and a second piece, wherein at least a portion of a periphery of the first piece is attached to at least a portion of a periphery of the second piece in order to form the hollow body.
  • At least one of the first piece and the second piece may comprise a flexible portion aligned with the cutting member, such that when the flexible portion is pushed towards the container the cutting member is indirectly pushed through the weakened portion, thereby forming the hole.
  • the first piece may comprise the cutting member, and the second piece may comprise the flexible portion.
  • At least one of the first piece and the second piece may comprise at least one spacing element providing for that a flow channel inside the hollow body is kept open.
  • At least one of the first piece and the second piece may be arranged to create a seal around the weakened portion, such that vent air is prevented from flowing into the container as liquid is dispensed through the hollow body.
  • the seal may be arranged such that a sub-atmospheric pressure within the container is formed during drinking from the container via the hollow body, such that liquid in the hollow body is forced back into the container as soon as a consumer removes the hollow body from his or her mouth.
  • the container may comprise creasing lines such that a change of shape of the container due to the difference between the external pressure and the internal pressure can be controlled.
  • a method for producing a package comprising a container and a hollow body, wherein the method comprises attaching a first part of the hollow body to a first section of the container, such that the first part is fixedly attached to the first section; and attaching a second part of the hollow body to a second section of the container, such that the second part is releasably attached to the second section.
  • the method may further comprise aligning the hollow body with a weakened portion of the container.
  • the step of aligning the hollow body with the weakened portion of the container may be made using at least one mark on the container.
  • a method for producing a hollow body arranged to be attached to a container comprises attaching a first piece made of a first material to a second piece made of a second material.
  • the method may further comprise attaching at least a portion of a periphery of the first piece to at least a portion of a periphery of the second piece, forming an attachment portion, in order to form the hollow body.
