Definitions

  • the present invention relates to a container.
  • the present invention has been developed in relation to wine containers of the kind commonly known as bag-in-box containers that have an outer box and an inner bag. It will be convenient to describe the invention in relation to containers of that kind which are employed for containing wine, although it is to be appreciated that the invention can be employed as a general container for containing other liquids or non-liquid objects.
  • Bag-in-box containers have been employed for containing wine for many years, it is normal for the box of the container to be formed as a carton having a body of generally square or rectangular cross-section and flaps which are integrally connected at either end and which are folded over each other to close each end.
  • the carton is typically made from a blank of corrugated cardboard.
  • Bag-in-box containers of the above kind are convenient and cheap to manufacture, however they suffer from various disadvantages.
  • a major disadvantage is that the stacking strength of the bag-in-box container is low. Typically about 360 bag-in-box containers can be loaded onto a pallet, stacked four or five levels high. However, such pallets cannot be stacked beyond two pallets high. This is disadvantageous during bulk transport and warehouse storage because warehousing or transport space can be wasted. Additionally, the limited ability to stack pallets of this type of carton is also a disadvantage for retail outlets, as many outlets would prefer to stack the pallets several high to reduce storage.
  • a further disadvantage of the above kind of prior cartons is that they are readily damaged during normal handling, because the cartons offer little protection to the bag within the carton against impacts that occur during transport and handling. Often such impacts can result in the bag being ruptured, so that the wine contained within the bag leaks and is spoiled by contact with air. Often the entire quantity of wine will leak out of the bag, saturating at least a portion of the carton, usually the base, so that the carton no longer provides any structural support. Where leakage of one carton occurs amongst other cartons, the leakage can also affect the structural integrity of the cartons of the other containers. Additionally, any leakage usually renders the carton unfit for sale. This problem causes the loss of a significant amount of wine sold in bag-in-box containers.
  • a further disadvantage of the bag-in-box type of wine container is that the aesthetic appeal of the container is low. For this reason, such containers have only usually been employed for low quality wines and retail outlets rarely place the containers in positions of prominence.
  • the present invention provides a container including: a tubular body having open ends, first and second end closures being formed separately from the body and being engaged with the body at each open end to close each end, the first end closure closing a bottom end of the container and being arranged to support a load contained within the container, the first end closure being reactive to the load to vary the engagement load between the closure and the bottom end of the tubular body proportional to the load.
  • the closure reacts in some way to the load within the container, in order to vary the engagement load between the closure and the bottom end of the body in proportion to the load.
  • the closure is thus not rigidly formed or static, but rather, it is formed in a manner that, when it is exposed to a load which it is to support, it reacts to that load, and the reaction is to vary the engagement load between the closure and the bottom end of the tubular body proportional to the load. Because of this reactive characteristic, the closure can be described as a dynamic closure, rather than a static closure.
  • the first end closure can be reactive to the load within the container in any suitable manner, such as in accordance with examples given below.
  • the first end closure can be somewhat self-locking, such that the load within the container contributes to the security of the connection between the body and the first end closure, and such that that security increases as the load increases.
  • the first end closure can support the load contained within the container in a manner such that the engagement load between the first end closure and the internal surface of the body, or the firmness of that engagement, is proportional to the load contained within the container so that as the supported load increases, so does the firmness of the engagement between the first end closure and the internal surface of the body.
  • the first end closure can be arranged to engage the inner surface of the tubular body to close the bottom thereof and this can be done in any suitable manner. In one arrangement, there is a force re-direction laterally from generally vertical. This lateral re-direction can be achieved by a portion of the first end closure being displaced laterally to the vertical load supported on the first end closure.
  • the end closure includes a flexible concave base which extends across an end of the body.
  • the curve of the concave base extends axially inwardly of the body, i.e. away from the open end, so that the weight of an object or objects supported by the first end closure during use of a container according to the invention, tends to cause the concave base to flatten and therefore to increase the diameter of the end closure slightly, to shift the portion of the end closure that engages the internal surface of the body more firmly into engagement with that internal surface.
  • Other arrangements to achieve the force redirection can also be employed.
  • the present invention further provides a container including: a tubular body having open ends, first and second end closures formed separately from the body and attached to the body at each open end to close each end. a bag enclosed within the body for containing liquid, the bag including a tap for dispensing liquid from within the bag, the container being formed to enable the tap to project from the interior of the container to the exterior.
  • Projection of the tap from the interior of the container to the exterior can be made through the body of the container, or through one of the end closures.
  • the container will preferably be oriented with the longitudinal axis of the body generally vertical when liquid is dispensed from the bag, whereas where the tap projects through one of the end closures, the longitudinal axis of the body will generally be horizontal during dispensing of liquid.
  • This latter arrangement is considered to be advantageous for containers that are to be stored in domestic refrigerators, as the vertical space required in the refrigerator is minimised and the liquid contents of the bag within the container can be dispensed through the end closure with the longitudinal axis of the body of the container remaining horizontal, i.e. the container does not have to be shifted to a vertical orientation to dispense the liquid.
  • the present invention also provides a container including a tubular body having open ends, first and second end closures formed separately from the body and attached to the body at each open end to close each end, the container being formed to enable a dispensing tap of a bag for containing liquid to project through the container from the interior to the exterior.
  • the container can be formed to enable the dispensing tap to project through the body, or one of the end closures. Indeed each of the end closures can be formed to enable the dispensing tap to project therethrough, so that the consumer can select which of the end closures the tap is to project through and so that the manufacturer is not required to position the bag with the tap adjacent to a particular end of the container.
  • the first end closure can support the load of the wine bag within the container, in the manner described in relation to the earlier containers, so that the engagement load between the first end closure and the tubular body, or the firmness of that engagement, is proportional to the load of the wine bag and so that as the supported load increases, so does the firmness of the engagement between the first end closure and the internal surface of the body.
  • the supported load can increase by an increase in the weight of the wine bag, or by movement of the container, such as lifting movement.
  • the first end closure is formed as described above to achieve a force re-direction laterally from generally vertical.
  • the arrangement described earlier to achieve this can be employed in a liquid container according to the invention.
  • the tubular body can be a cylinder, although the body could alternatively be elliptical in cross-section, or oval, or other suitable shape.
  • the tubular body could for example be triangular, square or rectangular in cross-section, although a cylindrical body is preferred for structural strength, in particular stacking strength, and ease of manufacture.
  • the tubular body can be manufactured by rolling or winding a suitable material into an elongate cylinder and cutting the cylinder into lengths suitable for a liquid container according to the invention.
  • a suitable material For example, an elongate cylinder of up to 950 mm can be produced and thereafter cut into shorter lengths.
  • the cylinder can be labelled or printed prior to being cut into shorter lengths.
  • labelling or printing can take place at the premises at which the bag is inserted into the container.
  • labelling or printing can be conducted at a winery for example.
  • the body of the container can be manufactured from any suitable material.
  • the preferred material is solid cardboard sheet or spiral wound cardboard, although corrugated cardboard or plastic, plastic sheet, metal sheet, or even timber could be employed.
  • spiral wound cardboard is readily available in cylindrical form, in various grades of thickness, i.e. 0.5 mm to 4 mm and strength.
  • Spiral wound cardboard can provide significant protection for an object contained within the tubular body of the container. Spiral wound cardboard is resistant to puncture and can have significant column strength, so resisting collapse. Compared to the corrugated cardboard that is used in prior bag-in-box arrangements, spiral wound cardboard significantly improves protection for a liquid containing bag and facilitates stacking in a manner not available to prior art bag-in-box containers.
  • Containers according to the invention can be stacked to a significant height.
  • a cylindrical container formed of spiral wound cardboard can be constructed for stacking to 5 pallets high or more, with the number of levels of containers stacked on each pallet being to 5 levels or more.
  • At least one of the first and second end closures is preferably attached to an end of the body by engagement with the internal surface of the body at that end and in each embodiment of the invention preferably each of the first and second end closures attaches to the ends of the body by engagement with the internal surface thereof.
  • one or each of the first and second end closures has a side wall which extends substantially parallel to the internal surface of the body and which frictionally engages the internal surface.
  • one or each end closure can include a peripheral channel within which a bottom edge of the body is received.
  • the opposed faces of the channel are spaced apart sufficient for those faces to frictionally engage opposed surfaces of the bottom edge.
  • the channel can be annular.
  • the channel can include a plurality of projections each of which projects into the channel from an opposed face of the channel to engage the bottom edge of the body.
  • At least the first end closure can include a flange or groove that is arranged to engage within a groove, or cooperate with a step or projection or other suitable arrangement formed or provided in or on the internal surface of the body.
  • This arrangement can be applied to one or each end closure as required.
  • the preferred arrangement is to provide one or each end closure with a flange, which is preferably an annular flange.
  • the or each end closure attaches to an end of the body by engagement with the internal surface of the body only

  • the concave or domed construction of the base 17 is highly advantageous, 5 because it causes the side wall 15 of the end closure 14 to more firmly engage the internal surface 16 of the open end 13 when a load is placed on the base
  • the Figure 3a arrangement has been employed successfully in a container according to the invention to support a liquid filled bag, although the arrangement of Figure 3 is considered to provide greater security of0 connection between the end closure 13 and the container 11.
  • the Figure 3 arrangement provides other advantages as follows: • Because a liquid container 10 can be exposed to high temperatures during shipping and the high temperatures can relax the stresses or memory in the plastic of the closure, the closure can shrink and thus reduce the frictional engagement between the closure and the body. By employing the lip 20, the closure is less prone to shrink because the lip resists shrinking or contracting movement of the closure.
  • the closure can be applied to a cardboard body when the body has just been fabricated and is wet or moist, such that the board is more pliable than when it has dried. Accordingly, the portion of the board that is received within the channel 21 will form closely to the shape of the channel, thus increasing the frictional or gripping load between the end closure and the body.
  • the end closure 14, or an end closure of similar construction can be employed to close the open or top end 12 of the body 11.
  • the form and operation of the end closure 14 has benefits for closure of the open end 12, particularly in a form of the container 10 in which a handle is formed as part of the end closure and the ioad within the container is lifted through the handle.
  • the end closure 14 will act in the same manner as described earlier, such that when the container 10 is lifted by an end closure 14 at the open end 12, the ioad within of the container will cause the concave base of the end closure to flatten and thus to engage the internal surface 16 or top end of the container 10 more firmly.
  • a plurality of projections 28 Disposed within the channel 21 of Figure 3, is a plurality of projections 28 that extend or bite into the bottom end 22 of the body 11. This arrangement is more readily illustrated in Figure 4.
  • the projections can be positioned on either of the facing side wails of the channel 21 , or on each of the facing walls. The projections can facilitate greater frictional or gripping connection between the end closure 14 and the bottom end 22 of the body 11.
  • the wall of the body 11 bulges outwardiy. This advantageously facilitates better grip between the end closure 14 and the bottom end 22 of the body 11 , by creating a reduction in the diameter of the bottom end 22 compared to the diameter immediately above it. The reduction in the diameter thus tends to restrain the end closure 14 against disengagement from the bottom end 22.

  • the end closure 30 has a side wall 37 which extends to a base 32.
  • the base 32 domed or is concave.
  • the end closure 14 can be considered as a "static" closure, in that, apart from the reduction in load bearing on the closure as the contents of the liquid bag is emptied, the closure 14 is generally always subject to a load causing its base 17 to flatten.
  • the end closure 30 is a "dynamic" closure, because when the container 10 is at rest, the closure is not subject to a load which tends to flatten the domed base 32.
  • the base 32 is immediately subject to a load relative to the weight of the container. While both closures 14 and 30 are reactive to loads to which they are exposed, it is desirable for the closure 30 to be more reactive than the closure 14, due to the different operating conditions under which they operate.
  • the closure 30 can be of a lighter weight plastic than the closure 14, or the wall thickness of the closure 30 can be thinner than that of the closure 14.
  • the number and placement of the stiffening ribs 42, 43 can be arranged to make the closure 30 less stiff and therefore more reactive than the closure 14. In relation to the ribs 42 of the end closure 30, the ribs can assist to disperse the lifting force radially towards the tubular body.

  • angle ⁇ reduces as the concavity of the base 32 reduces or flattens.
  • the side wall 37 deflects outwardly as shown by the arrows, as the base 32 flattens.
  • this outward deflection is the mechanism by which the closure 30 reacts to more firmly engage the internal surface of the container body to which the closure is fitted. Moreover, the greater the lifting load, the greater the reaction so that the more the base 32 will tend to flatten and the more the side wall 37 will tend to shift outwardly. Clearly, because the cylindrical container body resists outward deflections, the tendency of the side wall 37 to shift outwardly is resisted by the container body, with the result that the engagement load between the side wall 37 and the container body increases as the lifting load increases. In other words, the firmness of the engagement increases with increased lifting load.
  • the end closure 14 of Figures 7a and 7b acts in the same manner as the end closure 30, but in response to a weight load rather than a lifting load.
  • the angle ⁇ between the side wall 15 and the base 17 reduces when a load is placed on it, from the position shown in Figure 7a to that shown in Figure 7b so that the base 17 flattens and so that the side wall 15 shifts outwardly.
  • closure 30 is subject to load only when the container 10 is lifted, while at other times, the closure 30 will be unioaded. This iilustrates the static versus dynamic loading arrangements that the respective closures 14 and 30 are subject to.
