Definitions

  • the present disclosure relates to packaging and more particularly to a sustainable packaging system including a carton and a sealed liner assembly for shipping liquid, viscous, or particulate products.
  • Substantially rigid plastic containers with replaceable covers are commonly used to package and ship selected liquid and viscous materials in the nature of foods and food preparation materials, cosmetic preparations, detergents, and the like.
  • Such containers are sturdy, typically having a wall thickness in the range of about 75 Mils to about 90 Mils, and have a large mouth that renders them well suited for storing and dispensing a variety of viscous liquids, e.g., syrups, mustard, and cosmetic preparations.
  • a typical 20 liter empty bucket may weigh approximately 21 ⁇ 4 lbs.
  • bag & box assembly Another mode of shipping liquid products is the "bag & box” assembly in which a bag, made of flexible single or double ply plastic film and provided with a fitment for discharge of the bag's contents, is stored in a box made of corrugated cardboard.
  • the latter type of packaging system is well suited for free-flowing liquids such as vinegar, wine, detergents, and the like.
  • it is not well suited for viscous materials for a number of reasons. For example, it is difficult to remove all of the contents from the bag, due to the inability to scrape out the residual contents from the bag.
  • the present disclosure relates to a packaging system and more particularly to a sustainable packaging system including a carton and a sealed liner assembly for shipping liquid, viscous, or particulate products.
  • the present disclosure in one embodiment, relates to a packaging assembly for holding liquids, viscous material, or particulate material.
  • the packaging assembly includes a carton having side and bottom walls.
  • the packaging assembly also includes a self-supporting plastic liner that fits inside of the carton for containing liquids, viscous material, or particulate material.
  • the liner has either a substantially circular or substantially oval cylindrical side wall, a closed bottom end characterized by a bottom wall formed integral with said side wall, and an open top end having an outwardly-projecting rim.
  • the rim has a radially-extending flange portion, and a dependent skirt portion, wherein when the self-supporting plastic liner is inside of the carton, the radially extending flange portion supports the liner on at least a portion of the carton.
  • a lidding material is provided to seal the plastic liner.
  • a packaging assembly for holding contents may include a self-supporting liner.
  • the self-supporting liner may hold contents and having a side wall, a closed bottom end characterized by a bottom wall formed integral with the side wall, and an open top end having an outwardly-projecting rim, said rim comprising a flange portion.
  • the packaging assembly may include a peel-reseal lidding assembly.
  • the peel- reseal lidding assembly may include a first lidding material defined by at least one edge. The lidding material may be heat- sealed to the plastic liner at the at least one edge at the open top end operably sealing the contents therein.
  • a center portion of the first lidding material may be detached from a remaining portion along at least one edge such that the center portion is movable to expose a second lidding material thereunder.
  • the peel-reseal lidding assembly may include a peel-reseal lidding material defined by at least one edge that is sealed to the remaining portion and the center portion across the detached edge. The peel-reseal lidding material is resealable to seal the contents in the plastic liner when the lidding material is broken.
  • a packaging assembly for holding contents may include a self-supporting plastic liner for holding contents.
  • the self-supporting plastic liner may have a side wall, a closed bottom end characterized by a bottom wall formed integral with the side wall, and an open top end having an outwardly-projecting rim, said rim comprising a flange portion.
  • a skirt portion may extend at a downward angle away from the flange portion.
  • the flange portion, the side wall, or the skirt portion may include a plurality of positioning features defined by surface features.
  • the packaging assembly may include a peel-reseal lidding assembly attached to the flange portion.
  • the peel-reseal lidding assembly may include a first lidding material, a second lidding material, and a peel-reseal lidding material.
  • the peel-reseal lidding material may be defined by at least one edge that is sealed across a detached edge of a remaining portion and a center portion of the first lidding material. The detached edge allows the center portion to be movable to expose the second lidding material thereunder.
  • the peel-reseal lidding material may be resealable to retain the contents in the plastic liner when the lidding material is broken.
  • the present disclosure in another embodiment, relates to a packaging assembly for holding liquids, viscous material, or particulate material.
  • the packaging system includes a carton having side, top, and bottom walls, and a carton lid near the top wall.
  • the carton has a tear strip or perforation dividing the carton lid from the remainder of the carton.
  • a self- supporting plastic liner is provided inside of the carton for containing liquids, viscous material, or particulate material.
  • the liner may or may not be attached to the carton.
  • the liner has a side wall, a closed bottom end characterized by a bottom wall formed integral with said side wall, and an open top end having an outwardly-projecting rim.
  • the rim has a radially- extending flange portion, and a dependent skirt portion, wherein the radially extending flange portion supports the liner on at least a portion of the carton. Separation along the tear strip or perforation allows the carton lid to at least partially open and expose the liner within the carton.
  • the present disclosure in another embodiment, relates to a packaging assembly for holding liquids, viscous material, or particulate material.
  • the packaging system includes a packaging assembly for holding contents, comprising a self-supporting liner for holding contents.
  • the self-supporting liner includes a side wall, a closed bottom end characterized by a bottom wall formed integral with the side wall, and an open top end having a rim.
  • the packaging system also includes a lidding assembly comprising at least three layers.
  • the lidding assembly may include a first layer having a center portion and a remaining area adjacent the center portion with the center portion positioned at a predetermined distance from an edge of the first layer.
  • the lidding assembly may also include a second layer and an adhesive adhering the first layer and second layer such that the center portion is adhered to the second layer and remains adhered to the second layer while folding the second layer and the remaining area is adhered to the second layer but releases from the second layer while folding the second layer.
  • the lidding assembly may also include a third layer comprising a lidding material sealed to the rim of the self-supporting liner, wherein the third layer and at least a portion of the remaining area are fixedly adhered to one another.

  • the present disclosure relates to a novel and advantageous sustainable packaging system that may be used to ship liquid or viscous products or particulate matter.
  • liquid products for example thick viscous products such as thick paints and inks, cosmetic compounds, food glazes and fillings, drywall mud, thick roof sealants, powders and flakes, or like products have been packed for shipping or sale in pails or buckets made of materials such as steel or thick plastic.
  • a single traditional 20 liter bucket of this type may weigh approximately
  • Buckets or pails are also typically cylindrically shaped, making them inefficient for skidding or shipping because there is a substantial amount of unused space between one bucket and the next bucket.

  • the liner 120 may be self-supporting. However, the relative thinness of the liner may make the liner easily collapsible, which may significantly reduce the volume and cost of disposal as compared to traditional pails.

For instance, the liner may be shipped in truckloads of approximately 28,000 units compared to only 3,412 traditional buckets per truck. Increasing the number of liners that may be shipped in a single truck load can advantageously result in less truck loads needed to ship the packaging system of the present disclosure and therefore less greenhouse gases being produced.
