Definitions

  • the invention relates to a material packaging system, and particularly to a material packaging system comprising a receptacle incorporating means for removably retaining a plurality of nested liners.
  • Lined receptacles have long been known, but two constant problems have been the need to provide a close fit of the liner to the receptacle walls so as to assure entry of materials being packed solely within the liner and also to prevent the inserted liner from slipping to the bottom of the receptacle or onto the contents therein when one is dropping material into a lined receptacle. Moreover, removing a filled liner from the receptacle, searching for a replacement liner and installing the new liner in the receptacle can be tedious and inconvenient.
  • Prior receptacles have not solved these problems efficiently.
  • Prior receptacles often require complex, costly, multi-part holding or clamping structures, or are difficult to use even if simplified.
  • United States Patent No. 5,671,861 discloses a receptacle for removably holding a plurality of loop-handled plastic bags.
  • the receptacle includes cleats projecting upwardly from opposing inside walls and fingers projecting downwardly from other opposing inside walls.
  • the handles of the bags hang from the cleats with the balance of the bag opening pinned against the inside walls by the fingers.
  • United States Patent No. 4,938,380 discloses a trash receptacle provided with four ears, one at each corner, to support a bag liner preferably having incorporated handles.
  • the ears are intended to have the bag handles looped around them such that the bag's sides hug the container walls, thus assuring that all refuse is captured within the liner bag.
  • a tip of each ear protrudes beyond and above a rim around the opening, requiring the handles to be stretched over them, and a notch in the exterior of each ear near the container corner lies well below the rim, causing the bag's edges outside the handle area also to be held in desired relation to the walls.
  • United States Patent No. 3,825,150 discloses a molded waste receptacle having integral tabs formed in its side walls, the tabs being pressed inwardly to engage a rolled-over edge of a liner bag and pinch it against the receptacle wall when pressing is ended. Simultaneous manipulation of both a tab and the edge requires some dexterity, and furthermore, the occurrence of gaps between the liner bag and the wall is not prevented, allowing waste disposal to occur between liner and receptacle.
  • United States Patent No. 4,366,916 discloses a packing box for bulk quantities of flexible bags with carrying handles, the box being convertible into a packing unit for the bags, because of provision of pre-perforated front panel and side flaps, the latter folding upward to provide tabs upon which the bag handles are received. Control of gaps between bag and receptacle is not provided and the box is not a leak-proof unit because of the pre-perforations.
  • United States Patent No. 4,418,835 discloses a pair of wire brackets, each bracket supporting the handle of a liner bag and being fastened in spaced relation to the interior of a respective wall of a trash receptacle.
  • the spacing is necessary for accommodating the user's fingers while inserting and removing the bag, even though such spacing undesirably allows waste disposal to occur between bag and receptacle.
  • these internally-disposed brackets can present a barrier to easy removal of the liner even though the bag's handles are readily grasped.
  • United States Patent No. 4,498,652 discloses a wire rack for suspending a plastic bag by its handle loops in an open-mouthed state of the bag, a protective wall being present on one side only (the rack being fastened to a cabinet door on that side).
  • United States Patent No. 6,102,239 discloses a material packaging system according to the preamble of claim 1, including nested liners that were removably attached to each other to form a unitary liner structure and a receptacle having an attachment device for detachably securing the unitary liner structure to the receptacle.
  • the unitary liner structure had a second attachment device for detachably securing the second attachment device to the attachment device of the receptacle.
  • a drawstring within a circumferential sheath,for retaining the drawstring was provided for performing the detachable attachment.
  • Each of the liners had a pull grip for gripping the liner to remove the liner from the unitary liner structure and perforations disposed between the pull grip and the second attachment device for tearing the liner when a tearing force was applied.
  • An uppermost liner of the plurality of liners was thus removed from the unitary liner structure without substantially disturbing the positioning of underlying liners by gripping and pulling the pull grip of the uppermost liner to apply the tearing force to the perforations of the uppermost liner.
  • US -5,133,607 A teaches a plastic trash bag which includes an elastic drawstring, wherein the drawstring may expand to conform to a container over which the bag is placed but does not close the opening of the bag below the circumference at which the opening is formed when retracted.
  • US 6,019,244 discloses a portable, foldable, leak-proof bowl suitable for use by hikers and campers to provide drinking water to dogs and other pets.
  • the bowl comprises a flexible hoop capable of being twisted into at least two circles of smaller diameter, a foldable material attached to the hoop so as to define a circular bottom for the bowl and a side also made of a foldable material, said side being preferably in the form of a cone section tapering toward the top.
  • the material packaging system according to the invention is defined in claim 1.
  • a material packaging system 10 not forming part of the invention comprises a plurality of nested liners 12 for receiving a material (not shown). As best shown in Figs. 2 and 5 , each of liners 12 has a material-receiving mouth 14 at a top end thereof and at least two apertures 16 (or at least three apertures 16, as shown) through said top end. Liners 12 are closed at the bottom ends thereof.
  • System 10 further comprises a receptacle 18 adapted to removably retain nested liners 12 in an open configuration for receiving the material to be packed.
  • the material to be packed can be any material to be stored or disposed of, for example, waste material.
  • Receptacle 18 comprises a lip 20 and at least two external projections 22 (or at least three external projections 22, as shown) adapted to penetrate apertures 16 when liners 12 are positioned inside receptacle 18. As best shown in Figure 3 , the uppermost portions of liners 12 overlap lip 20. These features combine to removably retain nested liners 12 in receptacle 18. An uppermost one of liners 12 can be removed from receptacle 18 without substantially disturbing the positioning of underlying nested liners in the receptacle.
  • liners 12 should substantially conform to the shape of receptacle 18.
  • the rectangular liners 12 of Figure 2 are suitable for the rectangular receptacle 18 of Figure 1
  • the cylindrical liners 12 of Figure 5 are suitable for the cylindrical receptacle 18 of Figure 4 .
  • Receptacle 18 can be open at only the top end thereof. However, in other embodiments, receptacle can be, for example, open along additional areas, and can even be an open frame in which liners 12 are draped. In addition, receptacle 18 can include a lid, although this is not shown in the figures.
  • apertures 16 and projections 22 are factors for maintaining adequate functioning of system 10. There can be at least three spaced-apart apertures 16 and three corresponding projections 22, to ensure that liners 12 maintain a close seal over lip 20 of receptacle 18. Having less than three apertures 16 and projections 22 can result in gapping of liners 12 about lip 20, creating opportunities for the material being packed to bypass liners 12 and enter receptacle 18 directly. There is no particular upper limit on the number of apertures 16 and corresponding projections 22; however, there should not be so many that installation and removal of liners 12 is inconvenient.
  • Apertures 16 can be placed along the top end of liners 12, sufficiently spaced apart to avoid the aforementioned gapping problem.
  • Projections 22 are correspondingly spaced-apart on the outside surface of receptacle 18, so that they readily penetrate the corresponding apertures 16, as shown in Figs. 1 and 4 .
  • Projections 22 can be placed at any relative height along the outside surface of receptacle 18, depending on the desired proportion of each liner 12 to be used for lining the inside of receptacle 18. For example, projections can be placed about 10 cm down the outside surface of receptacle 18, so as to provide a readily grippable portion of liner 12 for removing and sealing liner 12 after it has been filled to the top of receptacle 18.
  • projections 22 can be placed closer to the top of receptacle 18 to minimize the proportion of liner 12 wasted (i.e. the proportion of liner 12 filled with material is maximized).
  • Apertures 16 are not loop handles for carrying liner 12, but rather are less than about 5 centimeters in diameter, or may be less than about 2.5 centimeters in diameter.
  • Projections 22 hook-shaped, and are placed on the outside surface of receptacle 18 with the hook opening in a downward direction, such that apertures 16 can slide over projections 22 and be held in place by the upward tension provided by the weight of liners 12 within receptacle 18. Projections 22 need not be hook-shaped, however. The shape of projections 22 is dictated by their effect on the ease of installing and removing liners 12 and the stability of the installation during use of system 10.
  • Figure 6 shows a retractable projection 22, which retracts from the wall of the receptacle to assume a downwardly angled position for receiving and holding liners 12 via apertures 16.
  • retractable projection 22 demonstrates that the projection need not be curved to function properly.
  • Non-limiting examples of suitable materials for receptacle 18 and projections 22 include metal, plastic, wood and cardboard. Projections 22 and receptacle 18 can be unitary or not unitary. other examples of suitable materials for liners 12 include plastic and paper.
  • Figure 2 shows the contents of a kit for retrofitting a conventional (or projection-free) receptacle to create a material packaging system not forming part of the invention.
  • the kit may include rectangular, nested liners 12 having four walls, each wall having a corresponding tongue 24 attached to a top end thereof.
  • Tongue 24 is adapted to overlap receptacle lip 20 and comprises one aperture 16 for receiving a corresponding one of four external projections 22, which are also included in the kit.
  • Tongues 24 can also be used to tie liners 12 closed after liners 12 are removed from receptacle 18.
  • Projections 22 may include adhesive backing 26 for attachment to the receptacle to be retrofitted.
  • Material packaging system 30 is an alternate embodiment of material packaging system 10.
  • material packaging system 30 includes a plurality of nested liners 40.
  • Nested liners 40 are formed as unitary liner structure 42. Each nested liner 40 has a material-receiving mouth 34 at a top end thereof. Nested liners 40 are closed at their bottom ends in order to permit them to retain received material.

  • the material to be packed is not limited and can include, e.g. waste material.
  • Receptacle 54 includes lip 48 extending outwardly from the top thereof. When nested liners 40 are disposed within receptacle 54, an upper circumferential region of unitary liner structure 42 can reset upon lip 48.
  • the shape of nested liners 40 should substantially conform to the shape of receptacle 54.
  • rectangular liners 40 of Figs. 7 and 8 are suitable for rectangular receptacle 54 shown therein.
  • the shape of receptacle 54 can be, for example, round and that round liners 40 are provided for round receptacle 54.
  • Receptacle 54 can be open at only the top end thereof. However, in other embodiments, receptacle 54 can be open along other areas. Furthermore, receptacle 54 can be an open frame in which nested liners 40 are disposed. Additionally, receptacle 54 can include a lid, although a lid is not shown in the drawings.
  • FIG. 9 there are shown cross sectional views of material packaging system 30.
  • unitary liner structure 42 is formed with sheath 58.
  • Sheath 58 can extend around the entire circumference of material-receiving mouth 34 at the top end of nested liners 40.
