Definitions

  • the present invention relates to the field of packaging, in particular to containers packaged into wrapped bundles for transport.
  • the bottles When lightweight plastic containers are packaged into bundles, the bottles are readily deformed making them more difficult to stack and to transport without damage. In an extreme case a shipping unit or pallet may collapse during transport or storage due to deformation of one or more of the containers. In particular when one or more rows of bottles are held together by a film in tension, the bottles at the ends of the rows, or corners of the bundles, carry most of the load imposed by the film in tension, and are most vulnerable to deformation.
  • a wrapped bundle comprising a plurality of lightweight plastic containers which requires less packaging material to be used than those known in the prior art.
  • a wrapped bundle which resists substantial deformation at the ends or corners when the outer wrapping layer is in tension.
  • wrapped bundles which are suitable for stacking into shipping units with greatly reduced risk of the shipping unit collapsing.
  • the object of the present invention is achieved by means of a wrapped bundle comprising one or more rows of plastic containers and an outer wrapping layer, the or each row comprising a container at each end of the row, each of the end containers comprising a handle, the handle being asymmetrically located on the container to provide a first side of each container which contains the handle, and a second, opposing, side of each container which does not contain the handle, and wherein the first side is more rigid than the second side, whereby the first side of the end containers is directed towards the outside of the wrapped bundle, and the second side of the end containers is directed towards the middle of the row.
  • the wrapped bundle consists of one row of containers, the row comprising from two to five containers, preferably two or three.
  • the wrapped bundle consists of from two to four rows of containers, each row comprising from two to five containers, preferably two or three.
  • the wrapped bundle comprises one or more rows of plastic containers and an outer wrapping layer, the or each row comprising at least two containers, each of the containers comprising a handle, the handle being asymmetrically located on the container to provide a first side of each container which contains the handle, and a second, opposing side of each container which does not contain the handle, and wherein the first side is more rigid than the second side, whereby the handles of adjacent containers are directed towards opposite sides of the wrapped bundle.
  • the outer wrapping layer of the wrapped bundle is preferably a film or tape in tension.
  • Suitable materials for the film or tape are plastic, especially polyethylene, polypropylene, polyester, polystyrene, polyvinyl chloride, acrylic, or combinations or laminates of these; or paper.
  • Figure 1 shows a perspective view of a bundle of four containers having two rows of containers, each row consisting of two containers.
  • the outer wrapping layer is not shown for clarity.
  • Figure 2 shows a perspective view of a bundle of six containers having two rows of containers, each row consisting of three containers.
  • the outer wrapping layer is not shown for clarity.
  • Figure 3 shows a perspective view of a bundle of eight containers having four rows of containers, each row consisting of two containers.
  • the outer wrapping layer is not shown for clarity.
  • Figure 4 shows a perspective view of an alternative embodiment of the invention comprising a bundle of four containers arranged in a single row with handles on adjacent containers directed towards opposite sides of the bundle.
  • the outer wrapping layer is not shown for clarity.
  • Figure 5a shows the wrapped bundle of figure 1 with part of the outer wrapping layer shown cut-away.
  • Figure 5b shows the configuration of a shipping pallet loaded with bundles.
  • the outer wrapping layer is not shown for clarity.
  • a "wrapped bundle" 20, 25 is a packaged unit which contains at least two containers 1.
  • the containers are held together by an outer wrapping layer 6 which is preferably a film or tape in tension. Hence very little movement of the containers relative to each other is possible.
  • the containers are oriented within the wrapped bundle with respect to each other, such that there is a minimum amount of deformation of the containers. This makes it possible to assemble the wrapped bundles into closely packed shipping units 30 for transport.
  • the lightweight container 1 herein can be made of a variety of materials, but preferred containers herein are made of a thermoplastic material or blends thereof, including blends of recycled and virgin plastic.
  • the lightweight container 1 of the invention first comprises a base portion 2.
  • the base portion 2 is the portion on which the container stands in its normal upright position.
  • the container further comprises a top portion 3 which will generally comprise an opening 4 which will allow filling and/or emptying of the container. Accordingly, preferred containers herein are bottles, however the present invention is also applicable to containers which do not have an opening, i.e. which need to be torn or otherwise ruptured to be emptied.
  • the container further comprises at least one side wall 5 which joins the top portion 3 and the base portion 2.
  • the present invention is not limited to containers of a particular cross section. When the container is of a generally cylindrical cross section, in a plane perpendicular to the container's vertical axis A (i.e. an axis which is perpendicular to the base), there is only one, continuous side wall.
  • Containers herein can alternatively have an ellipsoid cross section in which case they are considered to have two side walls. It is preferred that containers herein have four side walls and a substantially square or rectangular cross section. In particular for the purpose of providing containers which are suitable to be assembled in wrapped bundles 20 which are wrapped in films, it is preferred to have containers which have substantially flat side walls, i.e. containers of substantially square or rectangular cross section. Indeed, such containers allow best use of space, and provide shipping units and sub-units of good rigidity. However, lightweight containers having this square or rectangular cross section are vulnerable to deformation when packaged by an outer wrapping layer in tension.
  • any handle 10 must be located asymmetrically with respect to the main container axis A for ergonometric reasons.
  • the effect of this is that one side of the container, the side where the handle is located is inherently more rigid than the opposing side.
  • the middle container may be oriented in either direction. As shown in Figures 1 and 5a, if four containers are bundled together one possible arrangement is two rows of two containers.
  • the outer wrapping layer 6 preferably consists of paper or plastic film.
  • Containers according to the present invention can be assembled in bundles, then wrapped in either pre-stretched plastic films (stretch-wrapping) or in heat-shrinkable films (shrink-wrapping). In the latter case, the bundles wrapped in the film must be processed though a heating means for the film to shrink.
  • Preferred films in both cases are polyethylene wrapping films available for instance from Mobil.
  • Plastic films useful herein typically have a thickness of less than 250 micrometers, preferably less than 150 micrometers, and more preferably less than 50 micrometers.
  • the outer wrapping layer of the wrapped bundle is applied by shrink-wrapping, the plastic film being sealed around the bottles and shrunk in a heat tunnel.
  • the plastic film thickness for shrink-wrapping is 35 to 50 micrometers.
  • the outer wrapping layer of the wrapped bundle is applied by stretch-wrapping, the plastic film most preferably having a thickness of 10 to 30 micrometers.
  • the plastic film may aso be applied in the form of strips, for example, adhesive strips which may be wrapped around the wrapped bundle. Wrapped bundles according to the present invention preferably consist of a single height of containers, but the wrapped bundles can in turn be stacked.
  • the bundles may also be contained by paper wrapping.
  • a material which is formed as a cellulosic web, and which fulfils these requirements is suitable for use as the wrapping in the present invention.
  • the cellulosic web may be a laminate, a bonded compressed air laid web, or a wet laid web, although wet laid paper wrapping is preferred due to its tensile properties.
  • Paper having a basis weight of at least 40 grams per square metre, and preferably about 70 grams per square metre is preferred.
  • the paper should most preferably have a basis weight of less than 125 grams per square metre.
  • the most preferred material of construction of the wrapping is a wet-laid paper made from wood- or manila fibres, or a mixture of these. Both virgin and recycled paper may be used.
