Definitions

  • This invention relates to a container for packaging various products, including food products, and which is characterized by having an end closure on at least one end of the container which contracts or expands to accommodate expansion or contraction of the product packaged within the container.
  • Containers utilized for packaging various products are often subjected to increased or decreased pressure within the container which results from either the product being packaged under a vacuum or the product expanding after it is placed in the container. This is typical of food products in which as much air as possible is pulled out of the container so that the product is under a vacuum or the packaging of a food product, such as a dough or the like, wherein the product expands after packaging.
  • Composite containers including at least a paper body layer and a barrier liner layer and closed by paper end members also having barrier liner layers or metal end members are becoming increasingly more popular for packaging various products, including food products.
  • These container constructions include problems with the walls of the body portion buckling outwardly under increasing pressure within the container resulting from product expansion or contracting inwardly when a vacuum is pulled on a product being packaged within the container.
  • Composite container body portions while providing economic advantages, do not provide the strength of metal or plastic containers. Even the metal or plastic containers can have the problems of buckling or contracting side walls due to the above changing conditions within the container.
  • a container having a movable end closure for accommodating expansion or contraction of product contained within the container by increasing or decreasing the effective volume of space within the container and comprising the following.
  • An elongate body portion has opposed open ends and an inside surface.
  • An end closure is positioned at each of the open ends of the hollow body portion and is secured thereto for closing the container with the product contained therein.
  • One of the end closures is of a generally outwardly-facing cup-shaped configuration positioned inside the hollow body portion and having a radially-extending central portion of generally the same configuration and dimensions as the body portion and an accordion-folded side wall extending axially from the central portion toward the body portion open end and defining a free end area secured to the inside surface of the body portion at the open end and positioned so that the end closure central portion may axially move along the body portion inside surface toward or away from the body portion open end by contraction or expansion of the end closure accordion-folded side wall.
  • the body portion of the container and the contracting or expanding end closure are constructed of composite materials which preferably include a paper layer and a barrier liner layer.
  • the cup-shaped expanding end closure may be secured at the one open end of the container body portion by a seaming operation in which the end of the body portion defines an inwardly-curled U-shaped cross-sectional configuration and the free end area of the cup-shaped end closure is positioned within the inwardly-curled U-shaped body portion end and an adhesive is positioned within the U-shaped body portion end to secure the free end area of the end closure therein.
  • FIGs. 1 and 2 illustrate a preferred embodiment of a container, generally referred to at 10 , constructed in accordance with the present invention.
  • This container 10 includes an elongate hollow body portion 12 , preferably tubular in configuration, having opposed open ends 13 and an inside surface 14 .
  • the body portion 12 may be constructed of any suitable materials including or plastic, but is preferably constructed of spirally-wound composite materials including a paperboard layer 15 and a barrier line layer 16 in superimposed position inside the paperboard layer 15 .
  • the paperboard layer 15 may be composed of conventional spiral-winding paperboard or board stock having a thickness of between 0.010 and 0.042 inch, preferably between 0.015 and 0.030 inch, for example 0.021 inch.
  • the barrier liner layer 16 may advantageously comprise a flexible material such as a polymer, a metalized polymer, a silicate impregnated polymer or a lamination of property enhancing polymers or polymer coatings on polymers, foils or paper, lamination of paper, metalized paper, polymer, metalized polymer, silicate impregnated polymer or foil engineered in combination to achieve the desired level of barrier.
  • the container 10 further includes end closures 17, 18 positioned at each of the respective open ends 13 of the hollow body portion 12 and secured thereto for closing the container 10 with product P contained therein.
  • One of the end closures 18 is of a generally outwardly-facing cup-shaped configuration positioned inside the hollow body portion 12 and has a radially-extending central portion 21 of generally the same configuration and dimensions (e.g., circular with the same diameter) as the inside surface 14 of the body portion 10 .
  • the end closure 18 further includes an accordion-folded sidewall 22 extending axially from the central portion 21 toward the body portion free end 13 and defining a free end area 23 which is secured to the inside surface of the body portion 10 at the open end 13 and positioned so that the end closure central portion 21 may axially move along the body portion inside surface 14 toward or away from the body portion open end 13 by contraction or expansion of the end closure accordion-folded side wall 22 to increase or decrease the effective volume of space within the container 10 , as shown in Figs. 1 and 2, respectively.
  • the one end closure 18 may be constructed of any suitable materials which can be utilized to form the expanding and contracting accordion-folded sidewall 22 and otherwise perform as described above.
  • This end closure 18 may also include a disk-like member 24 secured to the radially extending central portion 21 .
  • the end closure 18 is preferably constructed of composite materials which may be the same as that utilized for construction of the hollow body portion 12 , as described above, or may include suitable layers of paper (25#/ream or 25# bleached kraft), low density polyethylene, foil (0.00035" aluminum) or film (metalized polyethyleneterephtalate) and polyethylene (10-20#/ream SURLYN®).
  • the cup-shaped end closure 18 is preferably secured to the open end 13 of the hollow body portion 12 by providing the open end 13 of the body portion 12 with a inwardly curled U-shaped cross-sectional configuration (as illustrated in Figs. 1 and 2) so that the free end area 23 of the cup-shaped end closure 18 may be positioned within the inwardly-curled U-shaped body portion end 13 and an adhesive, generally indicated at 26 is positioned within the U-shaped body portion end 13 to secure the free end area 23 of the end closure 18 therein.
  • the other end closure 17 is preferably a paper or metal (steel or the like) conventional end closure double seamed to the open end 13 in a manner well understood by those with ordinary skill in the art or may be constructed of any suitable material and secured to the open end in any suitable manner.
