Definitions

  • the field of the invention is paper containers.
  • Gazette. Bried. and ail other extrinsic materials discussed herein are incorporated by reference in their entirety. Where a definition or use of a term in an incorporated reference is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein applies and the definition of that term in the reference does not apply.
  • the third method simply crushes or folds opposite sides of one end of a tube to create a closure.
  • This method creates an inexpensive closure, but the bottom is irregular and the container generally will not stand upright on a fiat surface.
  • the container is also not substantially airtight, which can allow the container's contents to suffer moisture damage and oxidation unless a separate piece of material such as tape is applied over the seam.
  • the fourth method is a plastic end cap or plug.
  • Conventional plastic plugs include a bottom wall having a substantially circular peripheral edge and a sidewall that extends from the peripheral edge.
  • the outer diameter of the flange is typically larger than the inner diameter of the paper tube and thus the flange acts as a stop or limiting rim that prohibits the plug from being pressed completely into the paper tube.
  • U.S. Publication No. 2005/0173504 to Erdie discloses a modified plug for a paper tube that engages a folded end of the paper tube.
  • the inventive subject matter provides apparatus, systems and methods in which a fibrous package is formed from a tubular, fibrous material.
  • the fibrous package is preferably formed from a single piece of fibrous material, and is generally formed by rolling a flat fibrous material into a tube to form a tubular body. While the flat fibrous material could be roiled about itself several times in order to form a thick, fibrous wall, the flat fibrous material is preferably only rolled about itself at most twice so that each end. of the tubular body is easier to cut.
  • an end of the tube comprising the bottom could be cut to form sets of flaps, which could then be folded inwards towards a center axis of the tube, and is then sealed to be substantially air-tight.
  • the flaps are pushed inwards slightly towards the middle of the tube to form a depression to ensure that the package stands upright when placed upon a flat surface.
  • the phrase "can-type package” means a tubular container that has a closed bottom and an open top.
  • the term "open top” means that the package defines an opening that is ordinarily open during typical usage.
  • the term “closed bottom” means that the wall defines a bottom that is ordinarily closed during typical usage.
  • an ordinary shampoo bottle is a vessel having a wall with an open top because the cap is either removed or disposed in an open position during typical usage.
  • a Campbell's soup can with a pull tab top has a wall with an open top because the top is removed during typical. The bottom of such a soup can, however, is closed because the bottom is not removed during typical usage.
  • the open top has a pull-tab that opens the top during use.
  • fibrous material means materials characterized by a plurality of discrete fibers.
  • the filaments can be plant or animal derived, synthetic, or some combination of these.
  • plant-derived fibrous materials the filaments are at least predominantly of plant origin, examples of which include wood, papyrus, rice, ficus, mulberry, fibers, cotton, yucca, sisal, bowstring hemp and New Zealand flax.
  • fibrous wall means a wall comprising a fibrous material as a significant structural constituent.
  • the fibrous walls contemplated herein preferably have at feast 2, 5, 10, 20 or even 30 dry weight percent of fibers.
  • the fibrous walls have at least 80 or 90 dry weight percent of fibers.
  • Paper is generally a fibrous material that is usually made by pressing and de-watering moist fibers, typically cellulose pulp derived from wood rags, or grasses.
  • the fibrous material is rigid and is largely inflexible, as, for example, layered paper or corrugated cardboard.
  • the structure of a fibrous material that is substantially rigid will tend to bend or break if a great deal of pressure is placed upon it, in contrast to a flexible material that will tend to flex and return back to its original shape after the pressure is released.
  • each of the portions of the package comprising the fibrous material are all rigid, for example the walls of the tube and the ends of the tube.
  • an "adhesive" is any compound in a liquid or semi-liquid state used to adhere or bond items together.
  • adhesives could be pastes (very thick) or glues (relatively fluid). All commercially suitable adhesives are contemplated, including for example library paste or simply glue made from water, milk powder, vinegar, and baking soda (e.g., a biodegradable adhesive).
  • suitable permeation barrier materials include those disclosed in U.S. Pat. no. 7344784 to Hodson or U.S. Pat. Appl. no. 2005/0130261 to Wils (publ. June 2005).
  • Such adhesives are preferably made from a substance that provides a permeation barrier that is substantially impermeable to air, oil, and water.
  • a statement that a permeation barrier is "substantially impermeable" to air, oil and/or water means that a wall treated with that additive has a transfer rate of less than or equal to 50 ⁇ of air, water and/or sunflower oil per cm' per six-month period of time at room temperature and normal atmospheric pressure (STP).
  • the permeation barrier material is substantially impermeable to each of air, water and oil. It is contemplated that the permeation barrier material could be applied to parts of the package prior to assembly, or even after assembly.
  • the outer wall comprises a rolled paper material upon which the permeation barrier material has been coated. It is also contemplated that the permeation barrier material could be: (1 ) on an exterior surface or interior surface of the outer wall; (2) impregnated within the material forming the outer wall; or (3) disposed between the layers of the outer wall.
  • the walls comprise a rolled paper upon which an adhesive has been coated and/or impregnated between each layer of the rolled paper.
  • the walls could include one, two, four, six, eight, or more layers (wraps) of the paper/permeation barrier combination.
  • a "biodegradable material” means a material that will break down to at least 90% H 2 O, CO 2 , and biomass within a period of six months from the action of naturally occurring micro-organisms such as bacteria, fungi, algae etc. under favorable conditions.
  • every element of the jar which could include an inner wall, a cap, a cover, spacers, the bottoms, adhesives, and permeation barrier materials, are biodegradable.

  • the following discussion provides many example embodiments of the inventive subject matter. Although each embodiment represents a single combination of inventive elements, the inventive subject matter is considered to include all possible combinations of the disclosed elements. Thus if one embodiment comprises elements A, B, and C, and a second embodiment comprises elements B and D, then the inventive subject matter is also considered to include other remaining combinations of A, B, C, or D, even if not explicitly disclosed.
  • the can-type package could be formed by cutting an end of a paper container in at least two places, and preferably three or more, and then folding the separate members, or flaps, inward to form a closure. In this manner, it is possible to form a bottom of a paper container such that the separate flaps could interlock together. The formation of a can-type package by using inwardly-folded flaps is preferable in at least one major respect because the package does not require the creation and assembly of separate parts to form a bottom.
  • folding flaps together to form a bottom of a cylindrical can-type package could, have significant problems.
  • the package may be unstable on a flat surface because the flaps could create an irregular bottom surface.
  • the package's bottom exterior edge may be irregular, which could detract from the package's esthetics.
  • this type of closure is not substantially air tight, which could allow the package's contents to suffer moisture damage, oxidation and/or potentially leakage.
  • a can-type package 100 is shown having a body 101 that is cut in multiple places about the circumference at a bottom end to form a set of flaps 102,
  • the cuts may be parallel to the length of the package 100 and. exceed, the radius of the opening of the end.
  • the cuts Preferably, the cuts have the same length and orientation, although this is not required.
  • the resulting flaps 102 may be cut into any advantageous shape that is desired such that the flaps 102 interlock, overlap or simply meet at least one other flap 102. While it is possible that the flaps 102 may fail to meet substantially, preferably there is at least 2-5 mm of overlap between the flaps to ensure that when the flaps are folded over one another, the entire bottom of can-type package 100 is covered...
  • a second fold could be introduced into each flap 102, such that when the flaps 102 are folded inwards along crease 103 to form a bottom, the flaps 102 are disposed away from the bottom circumference of the cy lindrical body 101, towards the center axis of the tube.
  • the surface of bottom 105 is preferably flat.
  • the surface of the closed bottom 330 could, alternatively be pushed, in towards the center of the tube to form dimpled surface 335. The ensures that the bottom of can-type package 300 does not tilt in any manner one way or another when placed upon a flat surface.
  • the dimple preferably does not exceed the bottom edge 106 of the body 101. It is also possible to simply dimple the folded flaps 102 inwards without a second fold. Folding or dimpling may be advantageously accomplished, by forcing/folding/molding the flaps 102 with mechanical pressure over the interior and exterior surfaces of the flaps 102 and base radius.
  • glue or other adhesive could advantageously join at least some of the flaps 102 together substantially between the flap layers, or more ad vantageously by covering the entire interior flap surface(s) between the cylinder walls with the adhesive.
  • adhesive is used to substantially join together the flaps 102, the flaps 102 should be joined together in a manner such that the resulting bottom creates a reasonable level of air, water, and/or oil tightness by sealing all seams about the flaps 102.
  • While contemplated adhesives include liquid or hot melt adhesives that could immobilize the flaps 102 and create a substantial air tight barrier, once the flaps 102 and adhesive have set, preferred adhesives are biodegradable, such that the entire body of can-type package biodegrades when placed within a warm, moist environment for an extended period of time. In the embodiments where the flaps 102 do not substantially meet, the adhesive could serve to fill in the gaps between flaps 102 as the bottom of the package 100 for the portions not composed of the flaps 102.
  • Figure 2 illustrates an embodiment of a can-type package 200 having a closed bottom 204 formed from a set of flaps 202.
  • Can-type package 200 has a closed bottom 204 and fibrous walls 201 that help keep any contents within the can-type package 200 from spilling out, and has an open top 205 that allows a user to access the contents within the can-type package 200.
  • the fibrous walls 201 and closed bottom 204 are treated with a permeation barrier material to prevent any liquids or semi-solids from leaking out the walls or the closed bottom.
  • any liquid 320 housed within the lumen of can- type package 300 preferably sits below the top edge of can-type package 300 by at least 5% of the capacity of the container, and more preferably 7% or 10%.
  • Figure 4 illustrate an embodiment of a can-type package having a pull tab 410 incorporated into a closed flap 202
  • Figure 5 illustrates an embodiment of a can-type package 500 having a cap 510 that receives a top of the wall 520.
  • Other known enclosures allowing a user to access the contents of an open top of a can-type package could be utilized without departing from the scope of the invention.
  • Coupled to is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms “coupled to” and “coupled with” are used synonymously.
