Definitions

  • This invention relates to an improved method for filling and sealing an aseptic- food or beverage container and also to a container filled in accordance with the method of the invention.
  • One of the more common containers into which food or drink is aseptically packaged is a flexible bag which incorporates a filling valve called a back membrane sealing gland.
  • This gland consists of a rigid plastics neck from the bottom of which extends a radial shoulder which is secured to the interior face of the bag to be filled.
  • a back membrane is attached to the lower face of the shoulder to provide two or more passage ways for product to flow into the bag.
  • the bag is filled by attaching a filling nozzle to the neck of the sealing gland and pumping aseptically prepared food or drink into the bag under pressure until such time as the bag is full.
  • the filling nozzle is then removed and the sealing gland is flushed with superheated steam to remove any particulate debris f.rom the neck portion.
  • the back membrane is then heat sealed to the underside of the shoulder of the sealing gland to hermetically seal the contents of the bag therein.
  • a method of filling and sealing a sterilised container with aseptically processed matter through a ⁇ ealable inlet provided with a neck portion to receive a filling nozzle comprising the steps of:-
  • the inlet is flushed with superheated steam to remove any food or beverage particles therefrom.
  • the superheated steam is at a temperature of approximately 145°C so that it scours as well as flushes the inlet.
  • the inlet includes an annular shoulder attached to the interior of the container wall, the inlet further including a membrane attached to the lower face of said shoulder in such a way that aseptically processed matter can be admitted to the container between said membrane and the shoulder following which the membrane is secured to the shoulder to seal the inlet.
  • the membrane is heat sealed to the shoulder, the material of the membrane and the shoulder being compatible to enable them to be heat sealed together but sealing at a different temperature to that of the bag wall material.
  • the inlet includes a neck portion which is substantially filled with said hot melt adhesive.
  • Any suitable hot melt adhesive can be used provided that it is non-toxic and suitable for use with food products. For instance, an adhesive normally used for glueing food grade cardboard packaging can be used . If desired, the adhesive can also include a bacteriocidal agent for increased security. ----- - - -
  • the hot melt adhesive is preferably admitted to the neck portion at a temperature in the range from 140°C-200°C so that it will vapourise any moisture present in the gland neck.
  • the adhesive can be admitted to the inlet either manually or automatically.
  • an aseptic food or beverage container provided with a hermetically sealed filling inlet which is additionally sealed with a hot melt adhesive.
  • the container is a flexible bag but any other form of container such as a box could be used.
  • the inlet includes a neck portion attached to the container, the hot melt adhesive being located in said neck portion.
  • the inlet comprises a back membrane sealing gland wherein said neck portion is attached to a shoulder portion located inside the container and attached to the interior wall of ..the container, said back membrane being attached to said shoulder portion in such a way that food or beverage can be admitted to the interior of the container until the container is full at which time the back membrane is hermetically sealed to the shoulder to close the inlet.
  • Figures 2A and 2B are plan views of alternative filling glands for use with the container shown in Figure 1, and; Figure 3 is a view of the container shown in Figure 1 just prior to the inlet gland being sealed.
  • FIG. 1 a container in the form of a flexible bag having an upper wall la and a lower wall lb joined at their periphery by means of a hermetic seal 2.
  • a filling gland 3 moulded from a rigid plastics material is fitted to the. bag and comprises an inlet or neck 4 attached to a radially extending shoulder 5.
  • Spaced annular lips 9 and 10 define a collar 11 on the neck whose purpose will be e.xplained hereafter.
  • the shoulder 5 is shaped as shown in Figures 2A and 2B.
  • a back membrane 6 is attached to the shoulder 5 in such a way that food or drink can be admitted to the interior of the container between the shoulder 5 and back membrane 6.
  • the back membrane 6 can be line welded at 7 along opposite edges of the shoulder 5 as shown in Figure 2A. With this arrangement, product will flow into the container .in the two directions indicated by the arrows.
  • the back membrane 6 can be attached to the shoulder 5 by four spot welds 8 located adjacent each corner of the shoulder 5. With this arrangement, product can flow into the container in the four directions indicated by the arrows.
  • a clamp 14 engages the collar 11 on the sealing gland and raises the neck 4 up towards the.nozzle 15.
  • the mouth of the neck 4 is covered with a sealing membrane (not shown) which is pierced by the nozzle 15.
  • the chamber with.in the neck 4 above the back membrane 6 is then flushed with steam supplied from the nozzle 15 to sterlise the chamber.
  • Aseptically processed food or beverage is then pumped from the nozzle 15 into the interior of the container between the shoulder 5 and the back membrane 6.
  • the supply of product to the nozzle 15 is cut off and the upper surface of the back membrane 6 is cleared of any food or beverage debris by a combination of flexing the gland mechanically and flushing the surface of the membrane 6 with superheated steam supplied from the nozzle 15 at a temperature of the order of 145°C.
  • a heated annular sealing die 13 is raised to press the membrane 6 against the shoulder 5 to form an annular seal therewith around the neck 4 .
  • the material of the membrane 6 and the shoulder 5 are compatible in terms of being heat sealed together but seal at a different temperature to that of the wall material la, lb so there is nor risk of damage to the bag wall lb during sealing of the back membrane 6 to the shoulder 5.
  • the nozzle 15 is removed from the neck 4 and the filling gland is pressure tested to make sure that the inlet has been properly hermetically sealed. If it passes this test, then a hot melt adhesive 16 inserted into the neck 4 at a temperature of between 140°C and 200°C. This vapourises or flashes off any moisture which may be present in the neck and also forms a bacteria impe.rvious external seal within the neck 4 of the gland. If a food or drink particle or fibre has been left in the annular seal area between the membrane 6 and the shoulder 5, moisture in the neck or interior of the container would tend to hydrate the particle bridging the seal and create a "wicking" effect which would draw the microoganisms into the container.
  • the hot melt adhesive 16 By using the hot melt adhesive 16, even if there is debris bridging the seal between the shoulder 5 and the back membrane 6, the additional es ternal seal provided by the hot melt adhesive 16 will provide the necessary security to prevent the ingress of any microbiological material such as air borne organisms, bacteria, yeasts or moulds .
  • the hot melt adhesive 16 can be inserted in the neck 4 either manually or automatically and can also include a bacteriocidal agent to further increase security.
  • a suitable hot melt adhesive would comprise a polymer such as EVA, a resin (hydrogerated hydrocarbon), a plasticiser such as polybutene and an antioxidant such as butylated hydroxy toluene.
  • a polymer such as EVA
  • a resin hydrogerated hydrocarbon
  • a plasticiser such as polybutene
  • an antioxidant such as butylated hydroxy toluene.
  • B640/67SF is a long open time, medium tack holt melt adhesive which is suitable for use in applications which require good adhesion to plastics. B640/67SF will bond polyethylene, polypropylene and polystyrene and uses no silicone in any of its manufacturing or processing.
