Definitions

  • the present invention relates to a container or package useful for dispensing a liquid media, and more particularly, to such a package which is to be separated upon disposal for recycling and/or other environmental purposes.
  • products or consumables are fabricated from two or more materials, portions of which are recyclable and others which are not.
  • the materials may have different recycling requirements.
  • spiral-type paper or cardboard tubes are often used in conjunction with a metal end cap or plastic nozzle.
  • the tubular paper body has certain recycling requirements while the metal or plastic nozzle has yet different requirements.
  • To economically recycle such materials they must be separated, however, it may not be practical or feasible to separate the recyclable material(s). That is, to the extent that a cutting tool, e.g., a knife or saw blade, or special process step is required to separate the materials, the probability that the consumer will take the time, or make the extra effort to separate the materials, is significantly reduced.
  • a package for dispensing a liquid media which is environmentally advantageous for recycling and waste disposal purposes.
  • the liquid media package includes (a) a tubular body, (b) an end cap connected to the tubular portion for containing the liquid media, and (c) a mechanism for inducing stress at a point in the tubular body and responsive to pressure developed internally of the tubular body to cause failure and separation of said tubular body.
  • the package is fabricated from two materials, at least one of which is recyclable, and a score line is disposed therebetween.
  • Figure la is a broken away sectional view taken along line la-la of Figure lb illustrating a liquid media dispenser/package according to the present invention.
  • Figure lb is an end view of a dispensing end cap for a liquid media package, illustrating an example of an orifice pattern.
  • Figure 2a is an enlarged side sectional view of one of the orifices having a flap preloaded against an edge of the orifice to releasably seal the flow of liquid media.
  • Figure 2b is an enlarged view of the same orifice shown in Figure 2a wherein the flap is displaced to an open position in response to internal pressure developed within the package.
  • Figure 3a is a side sectional view of the liquid media package with the internal plunger assembly acting on the end cap to effect failure of the score line.

  • Fig. la depicts a sectional view of a liquid media package 10 according to the present invention for dispensing a liquid media L M -
  • the liquid media L M is a viscous fluid or slurry, such as those employed as condiments in the food service industry, e.g., ketchup, mayonnaise, mustard, etc.
  • the liquid media package 10 a includes a tubular body 12, a dispensing end cap 14 having a plurality of dispensing orifices 16, and a stress inducing score line 20 disposed between the tubular body 12 and the dispensing end cap 14.
  • liquid media package 10 is to be used in combination with a pressure generating device to cause failure of the tubular body 12 at the score line 20.
  • a plunger assembly 18 may be employed to develop the requisite pressures internally of the tubular body 12. The operation of the plunger assembly 18 will be discussed in greater detail when describing the remaining figures. While the illustrated embodiment describes a package/dispenser for a food product, it will be appreciated that the teachings herein are applicable to any liquid media container which dispenses a liquid product, e.g., caulking, adhesives, toothpaste, etc.
  • the liquid media package 10 may be fabricated from two or more materials each having unique recycling requirements. While each of the materials described herein may be recyclable, the invention is useful for any package having at least one recyclable material or one which produces an enclosed/sealed void after use. With respect to the latter, an enclosed or sealed void increases the disposal volume of the package and, as such, is environmentally inefficient and undesirable.
  • the tubular body 12 may be fabricated from, for example, a paper material, while the dispensing end cap 14 may be manufactured from a plastic or thermoplastic material. It will, therefore, be appreciated that these materials, i.e., paper and plastic, may need to be separated upon disposal to recycle one or more of the materials.
  • recycling is defined as a process to restore or return, in whole or in part, a material previously used in the manufacture of a structure, item or component to its original material properties, e.g., structural, mechanical, dielectric, etc.
  • the dispensing orifices 16 of the end cap 14 form a circular pattern for delivering/distributing the liquid media L M over a predetermined circular area.
  • a condiment in a circular pattern on a food product having a substantially circular shape such as a patty of ground beef, chicken or fish (not shown).
  • the orifice pattern may simply reflect or compliment the shape of the item upon which the material is to be dispensed or deposited, e.g., linear, polygonal, etc.
  • each dispensing orifice 16 is defined by a substantially U-shaped cutout 26 forming a three- sided flap 28.
  • the flap 28 is preloaded to a closed position against an opposing edge 32 of the cutout 26 while in Fig. 2b, the flap 28 is displaced to an open position in response to a first threshold pressure PI developed internally of the tubular body 12.
  • the preload configuration may be generated by a variety of methods and, in the illustrated embodiment, may be fabricated by forming a flap that may be formed against the inside edge 32 of the cutout 26.
  • the flexibility of the material enables the flap 28 to be preloaded against the outside edge 32 of the cutout 26.
  • a low modulus of elasticity for the material enables a torsion spring to be formed about an effective hinge 28 H for preloading the flap 28 against the edge 32 to seal the cutout 26.
  • a first pressure (denoted by vertical arrows PI) developed internally of the tubular body 12 by the plunger assembly 18 (see Fig. la) causes each flap 28 to open. That is, once the pressure PI (over the flap area) exceeds the preload spring force, the flap 28 will rotate about its effective hinge 28jj to dispense the liquid media L M - Conversely, when the plunger assembly 18 stops acting on the liquid media L M , the pressure is reduced, causing the flap 28 to close. Consequently, the flap 28 is entirely responsive, i.e., opens and shuts, to the pressure PI developed internally of the package 10.
  • the plunger assembly 18 includes a piston 44 which slides axially within a cylindrical bore 12 ⁇ of the tubular body 12 and a jacking rod 46 having a disc or plate 48 affixed to an end thereof.
  • axial motion of the piston 44 is effected by a trigger assembly (not shown) for engaging the teeth 46 ⁇ of rod 46 in much the same manner as a conventional caulk gun. That is, the teeth 46 ⁇ are engaged to incrementally displace the rod 46 and plate 48, and thus the piston 44, with each stroke of the trigger assembly.
  • a variety of mechanisms may be employed to displace the piston within the bore of the package and those skilled in the art will recognize those which best integrate for a particular application.
  • a conventional lever arm may suffice to displace the piston.
  • a conventional piston rod having a spherical ball connection may be employed to impart motion to the piston.
  • the liquid media package 10 is empty, and is separated at the score line 20 to facilitate recycling. More specifically, in Fig. 3 a, the plunger assembly 18 is shown acting on or abutting the back side surface 56 of the dispensing end cap 14 and applying a steady mechanical pressure P2 sufficient to separate the materials. That is, as a final step/operation, the operator actuates the plunger assembly 18 such that a second pressure P2, higher than the first pressure PI, is developed to fail the tubular body 12. Generally, this operation affects separation at the score line 20 about the circumference of the tubular body 12. While in Fig.
  • the piston head 44 is shown substantially parallel to the back-side surface 56 of the end cap 14, the piston head may be angled (not shown) to apply a greater force in one area of the tubular body 12 to effect failure in only one region of the body.
  • the plunger assembly (not shown) has been removed and the waste materials are separated to be recycled or otherwise disposed of.
  • the tubular body 12 may be scored in a variety of ways to locally reduce the tensile yield strength of the material and effect separation at a predetermined operating pressure.
  • the score line 20 is disposed about an internal circumferential surface of the tubular body 12.
  • the score line 20' is disposed about and external circumferential surface of the tubular body 12.
  • the tubular body 12 is employed with a pair of aligned score lines 20" on both the internal and external circumferential surfaces thereof.
  • the score line must leave a sufficient thickness of material on the side wall so as to withstand normal operating pressure, yet the material must fail at a second predefined pressure, which is higher than the normal operating pressure.
  • the wall thickness at the score line must be designed to withstand the pressures incurred during routine operation, i.e., through pressure PI as the liquid media L M is dispensed.
  • the wall thickness must also fail at the higher pressure P2.
  • the pressure P2 is contemplated to be a tensile load exceeding the tensile yield strength of the material over the cross-sectional area at the score line or a point of induced stress.
  • the package of the present invention employs a pressure generating device acting on a point of induced or concentrated stress, thereby separating the package as may be required to facilitate recycling. Furthermore, the invention may additionally serve to separate materials for preventing the formation of enclosed voids/unoccupied spaces. By separating or venting the unoccupied region the remaining package may be easily compacted to minimize waste volume. Furthermore, the invention synergistically employs the same pressure generating device used for dispensing the liquid media, i.e., in its routine or daily operation, and for developing a second pressure (greater than the first pressure) to fail/separate the package.
  • the operator needs only to depress or actuate the dispensing apparatus, e.g., the plunger assembly, a final time to separate the materials.
  • the separation step is, therefore, contemplated to be integrated with the same apparatus employed in its normal day-to-day operation. Accordingly, the time/effort involved to dispose of the materials (in a manner suitable for recycling or other environmental purposes) is negligible.
  • the teachings herein are applicable to any liquid media package which dispenses a liquid or slurry type product, e.g., a caulking, adhesives, toothpaste etc.
  • the liquid will be sufficiently viscous such that the gap between the flap and cutout or each orifice, particularly along the sides of the lap, does not result in flow of the liquid media therethrough.
  • the liquid media package 10 is shown to include a cylindrical bore 12 B for accepting a circular piston head 44, this combination is merely illustrative.
  • the body may have a variety of cross-sectional shapes (including square, elliptical or polygonal), provided that the pressurizing device include a plunger assembly or piston head having a complimentary shape.
  • a score line 20 is shown to circumscribe the tubular body 20, the score may extend over a small portion of the tubular body 12 to initiate a tear for separating the recyclable elements.
  • the stress inducement means may include a tear strip or other means to structurally weaken the sidewall of the package.
  • the second pressure P2 may be developed with a portion of the liquid media L M still remaining. That is, an end closure (not shown) may be employed to seal the orifices such that the second pressure P2 may be developed by the plunger assembly 18 as it acts on the liquid media and/or the end cap.
