Definitions

  • the invention relates to a packaging for hydrocarbon fluids. More particularly, the invention relates to a container having a flexible pouch within a more rigid exterior container.
  • Automobile service centers and other entities having a need for large volumes of hydrocarbon fluids such as motor oil, transmission fluid or brake fluid, generally stock these materials in 55 gallon (208 ⁇ 2 litre) drums or 5 or 6 gallon (18 ⁇ 9 or 22 ⁇ 7 litre) pails or 16 gallon (60 ⁇ 6 litre) kegs.
  • 55 gallon (208 ⁇ 2 litre) drums are extremely heavy and difficult to handle.
  • the circular shape of the drums gives rise to vacant space during transportation thereby decreasing the efficiency and raising the costs of transporting and delivering these fluids.
  • individual one quart plastic containers such as those typically purchased by individual consumers, may be used by larger volume users.
  • the use of individual packaging destroys the cost-savings achievable with larger volume packaging.
  • large volume use of individual quart bottles would unnecessarily generate large quantities of hydrocarbon-contaminated waste plastics.
  • oil residue is left in the quart bottles and such waste could be significant when used by large volume consumers. This last disadvantage is also a problem with 5 quart (5 ⁇ 68 litre) bottles.
  • “Bag-in-a-box” containers substantially meet these needs.
  • Most such containers utilize polymer pouches, such as polyethylene, as inner pouches which contain the liquid.
  • Polymers which may be used as pouches for hydrocarbon fluids must have both good mechanical properties and good resistance towards hydrocarbon fluids. With the latter property there appears to be a correlation between the nature of the hydrocarbon fluid and the polymer composition.
  • thin polyethylene films are extremely economical, flexible and transparent and have low moisture vapor permeability, such films are permeable to oil.
  • Increasing the thickness of the polyethylene material such that the material becomes practicably impermeable to hydrocarbons fluid is well known. However, to achieve sufficient thickness, flexibility is sacrificed and the resulting product is a rigid polyethylene container.
  • US 5 788 121 discloses a prior art bag-in-box usable for hydrocarbon fluids.
  • the bag of this package is made of several layers which are not bonded together.
  • One method to decrease the permeability of thin polyethylene films to hydrocarbon fluids involves laminating a poly-vinylidene chloride onto the polyethylene film.
  • laminates with sufficient thickness to block permeation of hydrocarbon fluids are brittle and easily ruptured.
  • Fluorinated polyethylene films are also resistant to hydrocarbon fluids but large scale production of such material is impractical and expensive.
  • the hydrocarbon fluids packaging of the invention meets these and other needs.
  • the invention provides a "bag-in-a-box" type packaging for hydrocarbon fluids having a flexible, collapsible, sealable interior bag or pouch which prevents leakage and sweating.
  • the hydrocarbon fluids packaging further includes a rigid container formed in a shape, such as a solid rectangle.
  • the interior bag or pouch is constructed of a polymer laminate which is suitable for the packaging of hydrocarbon fluids which has improved hydrocarbon resistance.
  • the polymer laminate is particularly suitable for use with automotive fluids, including for example, motor oils, automatic transmission fluids brake fluids and lube oils.
  • the laminate comprises at least three layers having outer layers of an alkylene polymer and at least one inner layer of an oriented nylon polymer,
  • the laminate comprises at least three layers having an inside layer of an alkylene polymer, an outer layer of an oriented nylon polymer and at least one inner layer of an oriented nylon polymer or aluminium.
  • the pouch is made from a one-ply oriented and cross-linked high density polyethylene film.
  • a hydrocarbon fluids container comprises a pouch made of polymer laminate having at least three layers comprising:
  • a hydrocarbon fluids container comprises a flexible pouch of oriented and cross laminated high density polyethylene; and a rigid box having at least one face, wherein the pouch is disposed within the rigid box.
  • the hydrocarbon fluids packaging comprises an exterior box having sufficient rigidity to support the weight of the packaging contents as well as to withstand normal shipping and storing stacking. Disposed within the exterior box is a pouch comprised of a polymeric film which is resistant to hydrocarbon fluids, thereby preventing leakage, rupture and sweating.
  • the hydrocarbon fluids packaging of the invention provides for a readily portable hydrocarbon fluids, storage and transfer system. For packaging hydrocarbon fluids, it is desirable that the package be high in tensile strength, high in elongation at break, high in puncture resistance, low in oxygen transmission, low in moisture transmission, and low in coefficient of friction.
  • FIG. 1 a perspective, exterior view of one embodiment of a hydrocarbon fluids packaging is shown.
  • the exterior box 1 is illustrated as a solid rectangle having four side faces 2, a bottom face 3 and two opposing top flaps 4 and 5 which, when closed, form a top face 6. These flaps may or may not be interlocking but should come together to form a closed face.
  • the exterior box may be in any shape or form as long as it is rigid enough to contain the pouch inside and be useful for protection of the pouch containing the hydrocarbon fluid and ease of transportation (rigid outer box).
  • the exterior box may be octagon, hexagon, square or rectangular.
  • the exterior box for ease of construction can be rectangle or square of any size useful for storage of hydrocarbon fluid and be readily portable.
  • top flaps 4 and 5 may include a die cut or punched opening to serve as a hand hold provided the exterior box is strong enough to withstand handling stresses.
  • Fig. 1 only top flap 4 is shown having a handhold opening 7.
  • a handhold is not necessary for the box and the box may or may not contain a handhold. If present, handhold is not limited to the opening shown in Fig.1 and can be in any shape or form as long as it can serve as a handhold.
  • At least one of side faces 2 includes a valve opening 8.
  • Each of handhold openings 7 and valve opening 8 may be entirely removed portions or alternatively, may be cut or punched so as to leave a flap along a perforation such that the flap may be folded in or out in order to create the opening.
  • FIG. 8 a perspective, exterior view of another embodiment of a hydrocarbon fluids packaging is shown.
  • the exterior box 10 is illustrated as a solid rectangle having four side faces (panels) 11, a bottom face 17, two opposing inner flaps 13 and 18 which, when closed, form an inner top face 70 and inner flap interface line (opening line) 16, and two opposing outer flaps 12 and 19 which, when closed, form an outer top face 71.
  • These flaps may or may not be interlocking but should come together to form a closed face with the opposing flaps.
  • the flaps 13 and 18, are adjacent to flaps 12 and 19 when the top face is open.
  • the exterior box can be rectangle or square of any size useful for storage of hydrocarbon fluid and be readily portable.
  • One or more side faces 11 may include a die cut or punched opening to serve as a handhold provided the exterior box is strong enough to withstand handling.
  • Fig. 8 no handhold opening is shown.
  • the edge of the inner flap or outer flaps that meet with the opposing flaps form can be straight, curved, and/or in angles as long as it closes to form the top face and an opening is created that provides ready access for the pouch.
  • top inner flaps 13 and 18 may include a die cut or punched opening to serve as opening for a valve 15.
  • both inner top flaps 13 and 15 are shown as together having a valve opening 15.
  • At least one of top outer flaps 12 or 19 may include a die cut or punched opening to serve as opening for a valve 14.
  • Each of handhold openings if any and valve openings 14 and 15 may be entirely removed portions or alternatively, may be cut or punched so as to leave a flap along a perforation such that the flap may be folded in or out in order to create the opening.
  • the valve opening 14 and 15 should be aligned in such a way that when both inner top flap and outer top flaps are closed, they are aligned to permit the pouch fitment to be inserted through both valve openings 14 and 15.
  • Box 1 and/or 10 may be made from a unitary blank, which, in its unassembled form, lies flat or substantially flat. Alternatively, box 1 and/or 10 may be made of several separate pieces assembled and joined together to achieve the final desired form or shape. Box 1 and/or 10 may have any enclosed geometry. For convenience of transportation and storage, either a solid rectangle or cube may be used. In one aspect of the invention, box 1 has the dimensions of 11.25 by 9 by 14.25 inches (28 ⁇ 58 by 22 ⁇ 86 by 36 ⁇ 20 cm), but it is one exemplary size that is convenient for a portable hydrocarbon fluid storage and any similar size that is convenient for a portable hydrocarbon fluid can be used.

  • U.S. Patent 3,934,066 discloses intumescent coating compositions which include resinous or non-resinous carbonifics.
  • resinous carbonifics include urea-formaldehyde resin, or resin forming mixtures containing an amino source such as urea, thiourea, melamine and the like; along an aliphatic aldehyde (or a source of aldehyde) such as formaldehyde, paraformaldehyde, trioxane or methylenetetramine, acetaldehyde and the like.
  • non-resinous carbonifics examples include carbohydrates such as starch, dextrin, sucrose and lactose; and polyhydroxy compounds such as glycerine, sorbitol, mannitol, pentaerythritol, dipentaerythritol and the like.
  • the intumescent composition may also include a spumific material which assists in the production of a thick, heat insulating carbonaceous foam.
  • examples of spumific compounds include mono- or di-ammonium phosphate, phosphoric acid, melamine pyrophosphate, ammonium sulfate, ammonium bromide, sodium tungstate and the like.
