Definitions

  • Another object of the present invention is to provide a new and improved flexible plastic film container for a viable fluid in which the fluid collecting and dispensing conduits attached to the container are kept in sterile condition before their utilization by being respectively enclosed in compartments integral with the container.
  • FIG. 1 is a fragmentary top view of one embodiment of the flexible plastic film container of the invention having a fluid storage compartment extending between a first and a second end compartment integral therewith, the first end compartment enclosing fluid collecting means and the second end compartment enclosing fluid dispensing means;
  • FIG. 3 is a fragmentary top view of the second end compartment of FIG. 1 opened and partly torn away;
  • FIG. 4 is an enlarged section of the fluid storage compartment and second end compartment taken along line 44 of FIG. 2 to illustrate the position of heat seal bars during the sealing operation of the container walls and of a fluid dispensing conduit to each other;
  • FIG. 6 is a fragmentary top view of another embodiment of the flexible plastic container of the invention.
  • a sealed, flexible, thermoplastic film container comprising a fluid stor-, age compartment disposed between a first end compartment and a second end compartment.
  • the compartments are defined and separated from each other by a first and a second heat seal extending across the container transverse to its length.
  • a fluid collecting conduit of thermoplastic material is disposed in the first end compartment.
  • a first end of said conduit extends into the storage compartment through the first heat seal and is permanently sealed to inner walls of the container by said first heat seal.
  • a thermoplastic fluid dispensing conduit disposed in the second end compartment, extends into the storage compartment through the second heat seal and is permanently sealed to inner walls of the container by said second heat seal.
  • each of the collecting conduit and dispensing conduit are releasably sealed together at their respective first ends by the first and second heat seals, respectively.
  • the compartments containing the fluid collecting and fluid dispensing conduits are closed by seals at their extremities.
  • Each compartment of the thermoplastic film container is thus defined by two seals which make it leakproof.
  • the fluid collecting and dispensing conduits are completely enclosed in their respective end compartments and thus retain their sterile condition until use when each of the end compartments may be individually and separately opened and, if desired, removed from the container.
  • the transverse heat seals defining the storage compartment may conveniently be made by applying heat onto both exterior walls of the container and, through the walls of the container, onto the walls of the conduit in contact therewith.
  • the expression inner releasable seal as herein employed means a heat seal of the conduit inner wall surfaces to each other.
  • the sealed portion of the conduit is flattened by the seal, which seal may be opened by applying a pinching pressure at an angle of to the flattened sealed portion such as, for example, by pinching said flattened portion of the conduit between the thumb and the forefinger.
  • FIG. 1 a flexible plastic container according to one embodiment of the invention comprising a flattened tube, generally designated as 10, of biaxially-oriented polyolefin film having a top wall 11 and a bottom wall 12 and divided by a plurality of transverse seals into three sealed, leakproof, sterile compartments, i.e., a fluid storage compartment 14 extending between two end compartments 16 and 18.
  • the first end compartment 16 contains two fluid collecting conduits 20 and 21 made of a resilient thermoplastic material such as polyethylene, for example.
  • the fluid colecting conduits 20 and 21 are completely enveloped within the end compartment 16.
  • the second end compartment 18 contains a fluid dispensing conduit 22, also made of a resilient thermoplastic material such as polyethylene.
  • the fluid dispensing conduit 22 is completely enveloped within the end compartment 18.
  • the conduits 20, 21 and 22 extend into the fluid storage compartment 14.
  • the storage compartment 14 is defined by two leakproof seals 24 and 26 transversely extending across the walls of the tube 10.
  • the seal 26 on the fluid dispensing end of the storage compartment is preferably oblique with respect to the longitudinal axis of the tube 10 to provide a sloping bottom for the storage compartment when the container is held vertically and to thereby facilitate the draining of the fluid from the storage compartment, such as blood, for example.
  • the end compartment 16 is defined by two spacedapart leakproof seals, i.e., the seal 24 separating it from the storage compartment 14 and a terminal seal 28.
  • the end compartment 18 is also defined by two spaced-apart leakproof seals, the seal 26 separating it from the storage compartment 14 and a terminal seal 30.
  • the collecting conduits 2t) and 21 are shown sealed off in two separate pockets formed in the compartment 16 by a seal 29 in order to provide for separate and individual utilization and control of each of the fluid collecting conduits. This separation of the conduits 20 and 21 is optional. Also, the number of collecting conduits may vary and there might be one, or three, or more conduits, according to the kind of fluid and fluid additives to be stored in the container.
  • a flattened tube 10 of flexible thermoplastic film material of predetermined length and flat width is provided in a manner well known to those skilled in the art.
  • the two conduits 20 and 21 are inserted between the walls 11 and 12 at one end portion of the tube in such a manner that they are completely covered by the walls and that the walls extend beyond the conduits.
  • the conduit 22 is inserted into the other end portion of the tube 10 in the same manner.
  • the preferred heat sealing operation, by electrical impulse heat sealing means, is illustrated in FIGS. 4 and 5.
  • FIG. 4 shows the conduit 22 between the walls 11 and 12 with one extremity of said conduit being flattened between the heat seal bars 32 and 34.
  • Each of said heat seal bars 32, 34 has an impulse ribbon 33, 35 respectively mounted thereon. The opposite pressure from the bars has urged the inner wall surfaces of the conduit 22 into contacting engagement. Electrical energy is then applied to the impulse ribbons 33 and 35.
  • each ribbon makes its own seal, i.e., the heat coming from the ribbon 33 causes the top wall 11 and the wall of the conduit 22 in contact therewith to be sealed to each other and the heat coming from the ribbon 35 causes the bottom wall 12 and the wall of the conduit 22 in contact therewith to be sealed to each other.
  • the conduit 22 is flattened by the bars, the heat from both ribbons penetrating through the walls of the tube into the wall of said conduit produces an inner wall-to-wall seal 27 in the conduit.
  • This seal is strong enough to resist leakage due to hydraulic pressure from the fluid stored in the storage compartment but yields and opens under a higher outside pinch pressure applied transversely to the sealed portion of the tube to break the seal.
  • the optimum conditions of time, pressure and heat may be readily determined by trial for the film and tubular conduit materials selected.
  • the seal 24 of the fluid collecting side of the storage compartment and the inner seals 27 in the fluid collecting conduits 20 and 21 are effected in the same manner.
  • terminal seals 28 and 30 are then made transverse to the flattened tube 10 to close the end compartments 16 and 18 and completely envelope and seal the sterilized tubes 20, 21 and 22 therein, and thus keep them in their sterile condition.
  • These terminal seals may be effected in any convenient manner, i.e., by heat sealing or by the use of an adhesive.
  • the seal 29 separating the fluid collecting conduits enclosed in the end compartment 16 may be made at the same time.
  • a further advantage of the sealed end compartment 18 is that in case of a leak through the seal 27 in the dispensing conduit, the compartment 18 constitutes an additional reservoir for the fluid stored in the storage compartment 14.
  • a secondary inner wall-to-wall seal 27' may be made in the dispensing conduit 22 before inserting said conduit into the tube 10.
  • This secondary seal serves as a safety seal to prevent leakage from the storage compartment 14, should some leakage occur through the releasable seal 27 and may be opened in any conventional manner.
  • an elongated plug inserted into the dispensing conduit may also be used.
  • the collecting and dispensing conduits should not contain any of the fluid stored in the compartment 14, in spite of the fact that said conduits, and the whole container assembly, are in a sterile condition.
  • the compartment 16 enclosing the collecting conduits is opened by tearing the seal 28.
  • the inner seals 27 in the collecting conduits 20 and 21 are opened by exerting pressure on said tubes and the storage compartment 14 is filled with the fluid to be stored therein.
  • the conduits 20 and 21 are closed by flattening them and effecting a permanent heat-seal across their flattened walls in a conventional manner.
  • the seal 30 of the compartment 18 is broken and the compartment removed as shown in FIG. 3.
  • the dispensing conduit 22 is connected to other fluid conveying means and the inner seal 27 is opened to drain the container.
  • FIG. 6 is shown another embodiment of the container of the invention.
  • the container of FIG. 6 is similar to that shown in FIG. 1 with the exception of the collecting and dispensing conduits 38, 39 and 40 which are longer and coiled in their respective compartments 16 and 18.
  • An additional heat seal 42 is made adjacent to the seal 26 to provide a sealed area at the edge of the container for a deep notch 44. This notch in the sealed area makes it possible to make a clean tear across the container along the seal line 26 and to separate the compartment 18 from the storage compartment 14 thereby fully exposing the conduit 40 for dispensing the stored fluid.
  • a sealed, flexible, thermoplastic container which comprises:
  • thermoplastic material disposed in said first end compartment and having a first end extending into said storage compartment through said first heat-seal and permanently sealed to the inner walls of said container thereby;
  • each of said collecting conduit and said dispensing conduit being releasably sealed together at their respective first ends by said first and second heat-seals respectively;
  • said container being closed by seals at the extremities thereof.
  • thermoplastic fluid collecting conduit is separately enclosed in the first end compartment.
  • each of the first and the second transverse heat-seals consists of two closely spaced parallel seals.
