Definitions

  • the present invention generally relates to product packages and, more particularly, to product packages constructed from plastic film.
  • Various small, granulated, or fluidic products are often sold or distributed in individual plastic packages resembling pouches, for example. Some such packages include transparent film such that consumers may readily identify the contents. Others may include labeling or other indicia for identifying the contents.
  • plastic packages are conventionally formed and filled in an automated process.
  • One conventional automated process includes a vertical form, fill, and seal (VFFS) process.
  • VFFS vertical form, fill, and seal
  • Fig. 1 depicts a conventional package 10 produced from a conventional VFFS process.
  • the package 10 is constructed from a single piece of transparent plastic film, for example, and includes a container portion 12, a top seal 14, a bottom seal 16, and a side seal 18.
  • the container portion 12 includes first and second side edges 12a, 12b, a top edge 12c, and a bottom edge 12d.
  • the first side edge 12a results from a fold in the plastic film.
  • the machine heat seals or otherwise secures the opposing edges of the film together to create the side seal 18 and form a hollow tube of film.
  • the machine heat seals or otherwise creates the bottom seal 16, which is disposed transverse to the longitudinal direction of the tube of film, thereby defining the container portion 12 with an open top where the top seal 14 will later be formed.
  • the open top end at this point, is disposed adjacent to an outlet of the feed tube.
  • the machine introduces a specified amount of flowable product into the container portion 12 via the feed tube.
  • the machine advances the film to another heat sealing device, for example, to create the top seal 14.
  • the machine advances the film to a cutter that cuts the film immediately above the top seal 14 to provide the filled package 10.
  • the conventional package is generally rectangular in shape.
  • the top and bottom seals 14, 16, as well as the top and bottom edges 12c, 12d of the container portion 12 are generally linear and disposed substantially perpendicular to the side seal 18.
  • the side edges 12a, 12b of the container portion 12 are slightly curved, or concave. This curvature is due to the container portion 12 containing product, and therefore expanding in a direction perpendicular to the side edges 12a, 12b, which draws the side edges 12a, 12b inward.
  • the conventional package 10 may be offered for distribution as a single unit (as shown in Fig. 1), or with a plurality of other similar packages in a bag or a box. Still further, a plurality of packages 10 may be offered for sale in a blister pack, where each blister stores a single package 10 containing product. Blister-packs may be beneficial for storing the packages 10 when the packages are constructed of a water-soluble film, for example. When being offered for sale or distribution, space may be limited for the storage of the package 10. Therefore, the top and bottom seals 14 and 16 may be folded over such as depicted in Fig. 2. The folded-over configuration of the package 10 may be especially beneficial for storing the packages in blisters of a blister-pack, which may have size constraints.
  • the conventional package 10 includes pointed corners 20 where the first and second side edges 12a, 12b meet the top and bottom edges 12c, 12d.
  • the first and second side edges 12a, 12b intersect the top and bottom edges 12c, 12d at angles ⁇ that are equal to or less than approximately ninety-degrees (90°).
  • One shortcoming of this conventional package 10 includes the concentration of stresses at the pointed corners 20 due to pressures generated within the container portion 12 of the package 10, especially when the package 10 stores a fluid product.
  • Another shortcoming of the conventional package 10 is that the pointed corners 20 disposed along the first side edge 12a of the container portion 12 are constantly exposed in a manner that increases their susceptibility to scraping against surfaces such as storage bins, counter tops, pocket liners, etc. Such scraping may cause the pointed corners 20 to tear, thereby leaking the contents of the container portion 12.
  • One embodiment of the present invention includes a product package constructed from a single sheet of film.
  • the single sheet of film is arranged and configured to comprise a container portion.
  • the container portion includes a side edge and opposing end edges. The end edges are disposed transverse to the side edge. At least one of the end edges of the container portion comprises a convex profile.
  • Another embodiment of the present invention includes a method of forming a package from a single sheet of film.
  • the method comprises wrapping the single sheet of film about a longitudinal axis of the film. Then, opposing sidewalls of the wrapped film are sealed together along a first path that is transverse to the longitudinal axis to form a first end seal portion.
  • the first end seal portion comprises an edge having a concave profile.
  • the opposing sidewalls of the wrapped film are sealed together along a second path that is transverse to the longitudinal axis of the film to form a second end seal portion.
  • the second end seal portion is longitudinally spaced from the first end seal portion.
  • the first and second end seal portions at least partly define a container portion that is adapted to contain a substance.

  • top and bottom edges 110c, 11Od intersect the first and second side edges 110a, 110b at corners 112 having angles ⁇ that are greater than ninety-degrees (90°) due to the convex curvature of the top and bottom edges 110c, HOd.
  • the top and bottom edges 110c, HOd may intersect the side edges 110a, 110b at angles ⁇ of approximately one-hundred and thirty- five degrees (135°), for example.
  • the corners 112 also include angular dimensions ⁇ of approximately one-hundred and thirty-five degrees (135°).

  • first and second side edges 110a, 110b of the container portion 102 may alternatively include slightly curved concave profiles. Such curvature may be the result of the container portion 102 containing a substance or other product.

Still further, a plurality of packages 100 may be distributed or offered for sale in a blister-pack, wherein each blister stores a single package 100 containing product. Blister-packs may be beneficial for storing the packages 100 when the packages are constructed of a water-soluble film or an edible water-soluble film. Additionally, when offered for sale or distribution, space may be limited for the storage of the package 100. Therefore, the top and bottom seal portions 104 and 106 may be folded over such as depicted in Fig. 4.

  • Another advantage of the curved top and bottom edges 1 10c, 210, 410c, 510c and 1 1 Od, 21 Od, 41 Od, 510d of the packages 100, 200, 400, 500 of the present invention includes the ability of the packages 100, 200, 400, 500 to more closely conform to secondary packaging constraints.

  • a still further advantage of the packages 100, 200, 400, 500 of the present invention includes increased aesthetic appeal and unique packaging, which allows consumers to readily identify the contents and/or the source of the product.
  • Yet another advantage of the packages 100, 200, 400, 500 of the present invention includes the fact that the corners 1 12, 212, 412, 512 include angular dimensions ⁇ that are greater than ninety degrees such that the comers 1 12, 212, 412, 512 are more blunt than the corners 20 of the conventional package 10 depicted in Figs. 1 and 2.
  • the corners 112, 212, 412, 512 of the packages 100, 200 of the present invention therefore do not protrude from the packages 100, 200, 400, 500 as abruptly as the corners 20 of the conventional package 10, thereby reducing the degree to which the corners 1 12, 212, 412, 512 frictionally engage surfaces such as container walls, for example, which tends to cause tearing and failure of the conventional packages 10.

Abstract

L'invention porte sur un emballage de produit (100) formé à partir d'un traitement de formage-remplissage-scellage vertical, comprenant un seul morceau d'un film conçu et configuré pour définir une partie de conteneur. Le conteneur comprend une partie de scellement supérieure (104), une partie de scellement inférieure (106) et une partie de scellement latérale. De plus, le conteneur comprend au moins un bord latéral plié (110a). Les parties de scellement inférieure et supérieure (104, 106) comprennent des bords concaves (110c, 110d) définissant des profilés convexes de la partie de conteneur. Les profilés convexes de la partie de conteneur croisent les scellements latéraux pour émousser, de manière avantageuse, les coins de l'emballage de produit pour réduire de manière avantageuse les contraintes localisées.
