Definitions

  • the present invention relates to improvements in and relating to flexible containers, and particularly but not exclusively to flexible inner containers for bag-in-box type arrangements.
  • the inner container of a bag-in-box type arrangement is filled in situ in an outer casing, from a collapsed and folded condition.
  • the known designs of container require an operator to attach a filling hose to either the inlet or outlet of the container. This usually requires the operator to reach down into the casing, which is hazardous.
  • the outlet and inlet are usually buried between the folds of the container, and hence difficult to locate.
  • Known designs of container also suffer from several disadvantages which are apparent during dispensing of contents therefrom. Firstly, a significant amount of material often remains in the container following dispen ⁇ sing, such material usually being that in the aforemen ⁇ tioned pockets. Also, during dispensing, the container often collapses in a manner that hinders dispensing.
  • a collapsible container with a port the container being arranged to be movable between a generally collapsed condition and a filled condition, the container comprising a top part, a bottom part, and a connecting means between the top and bottom parts, the top and bottom parts being folded with the connecting means collapsed therebetween when the container is in the collapsed condition such that the top and bottom parts unfold substantially sequentially as the container is filled with material through the port.
  • the container may be located in use in an outer casing.
  • the top part is folded in a manner that enables the top part to unfold into an open configuration as material is fed into the container.
  • the bottom part may be folded over the top part also in a manner which enables the bottom part to unfold into an open configuration as material is fed into the container.
  • the bottom part unfolds generally into its open condition from over the top part substantially before the top part unfolds.
  • the top part is folded in a manner whereby first portions located generally on opposite sides thereof are folded toward each other, and second portions, preferably similar to the first portions and on further opposite sides of the part are likewise folded toward each other, to lie, at least in part, over the first portions.
  • the said first and second portions define an opening, when folded, providing access to the port or a further port located preferably generally centrally in the top part.
  • the bottom part is folded in a manner whereby portions located generally on opposite sides thereof are folded towards each other, to lie on the top part and preferably with the fold axes of the said portions on the bottom part substantially parallel to the fold axes of one pair of portions of the top part.
  • at least one of two further, preferably similar, portions on the bottom part is folded to lie at least partly on the top part and the said positions of the bottom part preferably with portions substantially parallel to the respective fold line(s) of the said second portions of the top part.
  • a port is provided in the or one of said further portions of the bottom part.
  • the part is located in further portion that is not folded toward the other such that the port is generally accessible for connection to filling means.
  • the portions of the bottom part define an opening permitting access by an operative to the further port in the top part.
  • the opening defined by the portions of the bottom part is substantially above the opening defined by the portions of the top part.
  • the connecting part is collapsible between top and bottom parts before the respective parts are folded as defined above.
  • the connecting part may be collapsed by forming a waist therein, and lowering the top part onto the bottom part.
  • the top part is planar, and is attached generally around its peripheral edge to one end of the connecting part, which is preferably tubular.
  • the bottom part is also preferably planar and attached generally around its peripheral edge to the other end of the connecting part.
  • the top and bottom parts are generally circular, and the connecting part of circular cross-section. The respective parts may be attached by welding, adhesive or other suitable means.
  • an inner collapsible container for a bag-in-box type arrangement the container being substantially as defined in the sixth to the fourteenth paragraphs above.
  • the container may be folded to have any of the fea ⁇ tures set out in the sixth to fifteenth paragraphs above.
  • Figs. 1 and 2 are perspective views? and Figs. 3 to 6 are plan views of a container, showing sequential steps in the collapsing of the container according to the present invention, to a folded condition .
  • a collapsible container 10 with a port 12 is locatable in use in an outer casing (not shown) and movable from a generally collapsed condition (Fig. 6) in the casing to a filled condition (Fig. 1).
  • the container 10 comprises a top part 14, a bottom part 16 and a connecting part 18 between the top and bottom parts 14, 16, the top and bottom parts 14, 16 being individually folded with the connecting means 18 collapsed therebetween when the container 10 is in the collapsed condition, such that the top and bottom parts unfold substantially sequentially as the container 10 is filled with material through the port 12, towards the filled condition .
  • top part 14 and bottom part 16 are similar, each comprising a circular sheet of plastics material.
  • the connecting part 18 comprises a tubular length of similar plastics material, across respective ends of which are sealingly attached the top and bottom parts 14, 16.
  • the port 12 in the bottom part 16 is located off-centre.
  • a further port 20 is located in the top part 14 at a central position.
  • Fig. 6 shows the container 10 generally as it would be produced, and also generally in the configuration it adopts when filled with material, such as liquid. It is to be appreciated that the configuration shown in Fig. 1 may be distorted if the container 10 is used in a container of non-circular cross-section.
  • Fig. 2 shows the first stage of collapsing the con ⁇ tainer 10 into the collapsed condition.
  • the connecting part 18 is gathered generally midway along its length, to form a waist 22.
  • the top part 14 is then lowered onto the bottom part 16, such that the connecting part 18 lies therebetween in a generally concertinaed condition.
  • Fig. 3 is a plan view of the container 10 in a second stage of collapsing. Two portions 24, 26 on opposite sides of the top part 14 are folded toward each other to lie above the rest of the top part, and spaced apart, leaving the port 20 unobstructed.
  • the third stage is to fold two further opposite portions 28, 30 of the top part 14 generally toward each other about fold lines generally perpendicular to the fold lines of the portions 24, 26, such that the portions 28, 30 extend over and between respective ends of the portions 24, 26. Again, the port 20 is left unobstructed. Folding in the portion 30 reveals the port 12.
  • An opening 32 is defined between the free edges 34, 36, 38, 40 of the portions 24, 26, 28, 30 respectively.
  • the opening 32 allows access to the port 20 from above the container 10.
  • the fourth stage of the collapsing sequence is to fold two portions 44, 46 on opposite sides of the bottom part 16 generally toward each other about fold lines 48, 50 respectively.
  • the free edges 52, 54 of the portions 44, 46 respectively are spaced to leave the port 20 accessible from above.
  • fold lines 48, 50 are generally parallel with the fold lines 25, 27 of the portions 26, 24 respectively, so that the portions 44, 46 lie on top of respective ends of the portions 28, 30.
  • FIG. 6 The final stage in the collapsing sequence is shown in Fig. 6.
  • a further portion 56 is folded across the portions 44, 46, along a fold axis 57, which is generally parallel to the fold line 29 of the portion 28 such that the port 20 is still accessible from above the container 10.
  • the port 12 also remains accessible.
  • the container 10 is now in the collapsed condition for storage and transportation.
  • the container 10 In use, the container 10 is located in the collapsed condition in an outer rigid casing (not shown).
  • the port 12 is readily accessible to an operator and is connected to filling apparatus.
  • the filling apparatus is then activated, and liquid or powder material is pumped into the container 10 through the port 12.
  • the container 10 starts to unfold, generally through the reverse of the folding sequence described above.
  • the portion 56 tends to unfold first as the rest of the container pushes up from below.
  • the portions 44, 46 then unfold, such that the bottom part 16 is now generally unfolded from about the top part 14, and is located below it, on the bottom of the casing.
  • the connecting part fills with material, and the top part rises in the casing. It is found that with this particular configuration of folding, the container does not tend to snag the outer casing, and therefore does not require manual intervention during filling, to release the container 10 from the inside of the casing.
  • the connecting part 18 fills, and the top part 14 begins to unfold. This starts with the portions 28, 30 unfolding, followed by unfolding of the remaining portions 24, 26.
  • the container 10 continues to be filled, until full.
  • both ports 12, 20 are readily accessible to an operator for connection to filling apparatus. Moreover, the sequential unfolding of the container obviates the need for manual intervention, and therefore removes hazardous, and undesirable requirements of conventional containers.
  • the container 10 as described above is particularly suited for location in a cylindrical outer casing, but can be located in a suitable rectangular casing, or in the casing of any suitable cross-section. Moreover, the cross-section of the container 10 may be changed.
  • the container 10 may be suitable for use alone, without an outer casing.
  • the container 10 can be of any suitable cross-section, and one or more ports may be provided therein.
  • the container may be made of a material other than plastics material.
  • top and bottom and similar terms have been used in the specification, to reflect the orientation which is expected to be the most used, it is to be understood that other orientations could be used.
