Definitions

  • tubular composite containers that are sealed at both ends.
  • Conventional tubular composite containers typically include at least one structural body ply and are formed by wrapping a continuous strip of body ply material around a mandrel of a desired shape to create a tubular structure.
  • the body ply strip may be spirally wound around the mandrel or passed through a series of forming elements so as to be wrapped in a convolute shape around the mandrel.
  • the tube is cut into discrete lengths and is then fitted with end caps to form the container.
  • a composite container for products constructed with one or more openings or windows in the container wall to enable the consumer to view the product stored therein.
  • An opening or window into the container not only provides the consumer with the ability to compare the appearance of competing products, but also provides the consumer with confidence that the product does not have any defects, such as food spoilage in the case of food products, prior to making a purchase.
  • U.S. Patent No. 1,894,295 to Scandore discloses a method of constructing a container having a window covered with a transparent material, such as cellophane.
  • the container is constructed by spirally wrapping an inner ply of cardboard and cutting openings therethrough to provide sight openings.
  • a transparent material, such as cellophane is partially wound over or otherwise positioned on the exterior of the inner ply so as to cover the sight openings.
  • An outer layer of cardboard having openings cut therein to coincide with the openings in the inner ply is then wrapped over both the inner ply and the transparent material in a direction opposite to the direction of wrap of the inner ply.
  • a decorated outer wrapper having openings corresponding with the sight openings may be applied to the outer ply.
  • the composite container disclosed in the '295 patent is not particularly suited for storing food products, especially those which have a liquid component.
  • the transparent material does not provide an adequate moisture or gas barrier to seal the container and protect any stored food product from contamination or spoilage or to prevent wicking or leakage of the food product into and through the container wall.
  • aligning the sight openings cut in the consecutive plies of material when wrapping the plies around the mandrel to form a container also creates many manufacturing difficulties, especially where the constituent plies of material are wrapped at relatively high speeds, for example 400 feet per minute. Variations in ply speed and splices in the ply material can cause misalignment of the sight openings, resulting in excessive material waste due to the discarding of defective containers.
  • tubular composite containers for storing food products include a liner ply on the inner surface of the paperboard body ply.
  • the liner ply prevents liquids such as juice from leaking out of the container and also prevents liquids from entering the container and possibly contaminating the food product stored therein.
  • the liner ply is also resistant to the passage of gasses, so as to prevent odors of the food product in the container from escaping and to prevent atmospheric air from entering the container and spoiling the food product.
  • the liner ply provides barrier properties and the body ply provides structural properties.
  • Conventional liner plies most often include aluminum foil, which has good barrier properties and also has advantageous strength properties.
  • the liner is wound onto the mandrel prior to the winding of the body ply and must be sufficiently strong and stiff to be independently wound on the mandrel without stretching or wrinkling. Because of the support provided by the foil layer of the liner, such liners are known as "supported" liners. One or more polymeric layers are normally adhered to the foil to further improve the barrier properties of the liner and it is sometimes the case that the foil layer is not necessary for barrier properties, but is included in the liner only to provide support.
  • a continuous polymeric liner ply is advanced towards and wrapped around a shaping mandrel to create a tubular shape.
  • the liner ply is preferably comprised of a polymeric material having a low opacity such that the product in the container can be viewed through the liner ply.
  • a body ply and a label ply are advanced towards the shaping mandrel. Apertures are cut through the label ply at predetermined intervals along the length of the label ply. The location of the apertures in the label ply are registered. Apertures are cut through the body ply at predetermined intervals along the length of the body ply corresponding to the apertures cut in the label ply.
  • the signal from the encoder is communicated to a processing unit, which is also in electrical communication with the die cutter 23 for the body ply 12.
  • the processing unit is programmed with the distance of each die cutter 23,41 from the mandrel 26 .
  • sensors which are preferably attached to the ply reel (not shown) for the body and label plies, measure the ply speeds for the body and label plies and communicate this information to the processing unit.
  • the signal to the processing unit generated when the encoder reads the eye mark on the label ply 15 initializes the processing unit.
