Definitions

  • the invention relates to the dispensing of fluids from flexible plastic containers.
  • Such flexible plastic containers are commonly plastic bags provided with a dispenser system welded to the open-ended bag prior to filling, a manufacturing process that is expensive and time-consuming and often leads to an accelerated ingress of air into the bag via the dispenser and to a possibility of contamination, also via the dispenser system-
  • the present invention provides a cheap and convenient dispensing system in which the flexible plastic container is punctured only at the commencement of dispensing, and in which a variety of styles of dispensers can readily be utilised.
  • the present invention consists of a container for containing flowable material said container having a main chamber, a dispensing chamber communicable with the main chamber and a dispensing nozzle captured within the dispensing chamber, the arrangement being such that the application of force can cause the dispensing nozzle to pierce the wall of the dispensing chamber allowing the contents to be dispensed from the container via the dispensing nozzle.
  • the container is made from a flexible material.
  • the flexible material can be plastics film-
  • the flexible material can be a barrier film.
  • the dispensing chamber can be positioned at an end or corner extremity of the container.
  • the dispensing chamber can be positioned between two flanking main chambers.
  • the container can include a sealing cap for sealing the dispensing nozzle once it has been used.
  • Another aspect of the invention consists in a container for containing a material, said container comprising:
  • said means providing a sealed environment for a fluid material, said means defining a main chamber and a dispensing chamber, said dispensing chamber being in a fluid communication with said main chamber, and at least part, if not all, of said dispensing chamber being formed by a flexible plastics material (laminated or not), and
  • Said means providing a sealed environment for a material can be a bag structure formed from a film of flexible plastics material having appropriate seals between piles to define said dispensing and main chambers.
  • Said means providing a sealed environment is formed substantially flat from overlying regions of a flexible plastics material that has been folded and/or sealed one ply to the other to define the sealed environment and the two chambers.
  • Said dispensing member can be an elongate member where the penetrating region is substantially of constant external cross section save for the sharp extremity region thereof and said region to remain captive defines a shoulder from the region of substantially constant cross section which assists in its remaining captive within said dispensing chamber-
  • Said dispensing member can be elongate and said conduit longitudinally extends from the captive region to the sharp extremity region.
  • the present invention consists in, in combination, a container as previously defined and a complementary dispensing member adapted to mate with said dispensing member, said complementary dispensing member facilitating the penetration of said plastics material by being positionable against the plastics material from the outside and having a passage way into which said penetrating region can be engaged, the engaged condition enabling a discharge of material to be dispensed from the container via an outlet defined by said complementary dispensing member.
  • the complementary dispensing member includes means whereby its outlet can be closed.
  • Said means whereby the outlet of said complementary dispensing member can be closed includes a capping member screw or otherwise engageable to close the outlet of said complementary dispensing member.
  • a further aspect of the present invention consists in a method of opening a sealed plastics container containing a material, said contained having sharp hollow probe confined in a separate chamber having access to the contents of the container as a whole, which method comprises, by exterior manipulation of said probe relative to an exterior wall of the container, forcing part of said sharp hollow probe through an exterior wall of said container and engaging the same within a dispenser having means to seal about said hollow probe at a region thereof exteriorally of the container and having an outlet capable of being opened or closed to control the flow of materials from said container via said sharp hollow probe into and out of said dispenser.
  • Said dispenser member can fit on said sharp hollow probe and extends to or substantially to the container wall and said sharp hollow probe is retained in said separate chamber of said container at least in part by a shoulder at or substantially at the inner surface of the container wall.
  • Said container can be made of flexible plastics material enabling manual manipulation of said sharp hollow probe relative to the wall through which it is to at least partly penetrate to mate with said dispenser.
  • the present invention consists in, in combination, a flexible plastics container for materials provided with a sharp hollow probe confined in a chamber separate from the main storage chamber of the container but having access to the contents thereof, and
  • Said flexible container can be a plastics bag and the separate chamber containing the probe has been formed by welding between overlying piles in a corner of a substantially flat plastics bag, a gap in a weld line to provide access to the main chamber of the bag.
  • said dispenser is recloseable.
  • a flexible plastic container for materials is provided with a sharp hollow probe confined in a separate chamber formed in the body of said container with access to the contents thereof and the consumer is provided with a complementary mating dispenser such that to effect dispensing of the contents of the container the consumer mates the probe with the dispenser so piercing the wall of the container and allowing the contents of the container to be dispensed through the dispenser.
  • the flexible plastic container would comprise a plastic bag, and the separate chamber to contain the probe, could suitably be formed by welding in a corner of the plastic bag with access to the contents of the container.
  • the process of the invention is equally applicable to more complex forms of flexible plastic containers such as, for instance, the flat bottom flexible containers manufactured in the USA by Jebco Packaging Systems of Atlanta, Georgia in which circumstances the separate chamber could be formed in the neck area of the container.
  • the sharp hollow probe should be confined within the separate chamber in such a manner as to allow ready and convenient manual mating of the probe with its complementary dispenser and free access of the contents of the container to flow through the dispenser via the hollow probe during the dispensing process, which would normally by under gravity or by squeezing the container.
  • the sharp hollow probe may suitably by tubular and may have one or more internal channels connecting one end of the probe with the other to allow free flow of contents from the flexible container through the dispenser via the separate chamber-
  • the complementary mating dispenser may be recloseable and will have a dispensing orifice as required by the nature of the fluid contents of the container and by the required use of the said contents by the consumer.
  • the container including the probe confined in its separate chamber may suitably be sterilised by radiation treatment, and the complementary mating dispenser would also be so sterilised, suitably packaged to maintain sterility until required for use.
  • the invention is applicable to a very wide range of flowable materials, but is particularly useful in the packaging of fluids where security from tampering, airtightness and sterility is important, since once filled and sealed the container retains its integrity until punctured at the start of the dispensing process.
  • barrier films of which there are very many known in the art the barrier properties of the flexible container can be optimised to obtain the desired shelf-life of the contents thereof.
  • Figure 1 shows a probe or dispensing member in accordance with one possible aspect of the present invention [preferably formed from a plastics material such as polypropylene (it could be a metal or other material)] located in a separate chamber formed by overlying (preferably with a fold) plies of a plastics film and thereafter selectively heat sealing the plies to define the sealed environment and to differentiate a separate chamber or a plastics material
  • a plastics material such as polypropylene (it could be a metal or other material)
  • Figure 2 is a view AA of the sharp or sharp extremity region end of the dispensing member or probe showing the longitudinal conduit thereof and how that extends from its inlet to the plurality of openings at the sharp extremity region,
  • Figure 4 is a sectional transverse view similar to that of Figure 2 but this time of the complementary dispensing member [preferably of a plastics material such as LDHB] which can engage about the region of substantially constant exterior cross section that forms part of said flexible plastics material penetrating region of the probe or dispensing member, there being at that end thereof in sue to be remote from the plastics container a threaded region over which a cap member can fit to seal the container, there being shown an appropriate form of opening that can be modified and/or redirected as appropriate for a specific material,
  • the complementary dispensing member preferably of a plastics material such as LDHB
  • Figure 5 is a view of a cap member sectioned in its bottom part to show the internal thread which will engage with the external thread of the member of Figure 3, and
  • Figure 6 shows Figures 2, 4 and 5 combined as they would be once the probe or dispensing member has been forced through the exterior wall of a container (preferably under the complementary action of the member of Figure 4 while capped with the cap of Figure 5).
  • Figures 7. 8 and 9 are side views of containers in accordance with further aspects of the present invention all of which include main and
  • a bag 1 is formed by folding an appropriate plastics material such as polyethylene or laminates of various materials (with or without any barrier materials) about a fold line such as 2 and thereafter sealing with weld lines 3, 4 and 4 to provide the separate or dispensing chamber 6 in which the probe or dispensing member 7 is held captive but which can communicate via the access provided by the break at 8 in the weld line 4 which communicates with the main storage chamber 9.
  • an appropriate plastics material such as polyethylene or laminates of various materials (with or without any barrier materials) about a fold line such as 2 and thereafter sealing with weld lines 3, 4 and 4 to provide the separate or dispensing chamber 6 in which the probe or dispensing member 7 is held captive but which can communicate via the access provided by the break at 8 in the weld line 4 which communicates with the main storage chamber 9.
  • the probe 7 is shown in Figure 2 having an enlarged end 10 preferably defining a should 11 which will not protrude through the film 11 (see Figure 6 which provides the exterior wall to the dispensing compartment 6).
  • the probe or dispensing member 7 has preferably an elongate shape having an elongate bore or passageway 12 which opens preferably into openings 13 at its sharpened end adapted to break the film 11 and cause the film 11 to ride up over and preferably still seal with the exterior surface preferably of constant cross section 14 until such time as that seal is enhanced by the butting arrangement of the end 15 of the complementary dispensing member 16 therewith as shown in Figure 6.
  • the complementary dispensing member has a threaded region 17 about which a cap 18 by an internal thread 19 can engage thus closing an outlet 20 (see Figure 6) between or prior to the dispensing of any fluid (liquid or powder) from the chambers 6 and 9 of the bag.
  • the member 16 can be used simultaneously to constrain that area of the exterior wall through which the probe is to be thrust.
  • the container is triangular with the dispensing chamber 23 being at the narrowest portion.
  • the dispensing chamber 23 is formed at one side of the container. In Figure 9 the dispensing chamber 23 is positioned at the centre of the main chamber 22.
