  • a typical use for milk packaged in such a fashion is for inclusion in hot beverages such as tea or coffee.
  • Other uses are, however common. It is known to package
  • Such milk has a shelf life longer than fresh milk and/or is capable of long term storage in non-refrigerated conditions.
  • Most typically, such milk is sterilised by a heat treatment, most preferably by ultra heat treatment, known as UHT.
  • UHT ultra heat treatment
  • the fat content of packaged milk may have a range of different fat contents.
  • the most common types of milk packaged are skimmed milk at 0.5% fat by weight, semi-skimmed at 1.5% fat by weight, whole milk at 3.8% fat by weight, single cream at 15% fat by weight, or double cream at 38 - 44% fat by weight.
  • Other fat levels may be offered.
  • the adjustment of the fat level of the milk to that desired occurs by either the addition or removal of fat as required.
  • the package is a flexible envelope comprised of a single piece of flexible film in which a first pair of opposite edges are bonded together so that the film substantially forms a tube along the longitudinal extent of the bonded edges, the walls of a first portion of the tube are bonded together creating an open mouthed receptacle with the open mouth defined by a first end of the tube, and, once sterilised milk has been introduced into the receptacle, and the walls of the tube adjacent the open mouth are bonded together so sealing said envelope.
  • the present invention further provides a milk package comprising a flexible envelope comprised of a single piece of flexible film in which a first pair of opposite edges are bonded together so that the film substantially forms a tube along the longitudinal extent of the bonded edges, the walls of a first and a second portion of the tube are bonded together enclosing a portion of the tube between the first and second bonded portions, said enclosed portion being suitable for the storage of a quantity of milk.
  • the film is dispensed from a roll of said film and the process of manufacture of the packaging occurs on a continuous basis.
  • the different steps in the manufacture of the packaging occur at different positions in a production line.
  • the method of creating the packaging may include an additional step of cutting the plastics material to an appropriate length either before or after filling of the package with sterilised milk product.
  • the film used in the present invention is most preferably made from a food grade plastics material. Other materials such as metal foils or composite materials may also be used.
  • the bonding of the various edges of the plastics material to form the package is performed by a heat sealing means.
  • the bonding maybe achieved using aknown adhesive.
  • the bonding of the first pair of edges is such that a flange which extends outwardly from the tube formed by the bonding is created.
  • said bonding is a continuous bond created by passing the edge to be bonded between a pair of heated rollers, in which the rollers are of sufficient temperature to partially melt the plastics film and cause the first pair of edges to fuse with each other.
  • the completed packaging is of a substantially longitudinal stick shape when filled and the bonding of the first pair of edges extends along the longitudinal length of the stick.
  • the formation and filling of the packaging occurs in the following steps:
  • a length of plastics film is fed off a roll, and through a die which causes the lateral edges of the plastics film to abut;
  • step (3) The open mouthed tube formed in step (3) is orientated substantially vertically with the open mouth uppermost;
  • a further step of cutting a nick into one or both of the sealed ends of the package may be included, either before or after step (7) in the above scheme.
  • the nick allows a user of the contents of the packet to easily tear the plastics material and gain access to the packet.
  • one or both of the sealed ends of the package is configured in the following fashion: the overall outline of the sealed end is substantially rectangular with a substantially "V" shaped indent extending into the edge of said substantially rectangular portion adjacent the contents of the package.
  • the user may tear across the sealed portion so that the tear line intersects the "V" shaped indent and passes back into the sealed portion. This creates a spout through which the contents of the package may be poured.
  • the package of the present invention may be provided with a nick in the edge of the sealed portion in such a position as to predetermine the size of the spout formed for pouring out the contents of the package.
  • the nick may be placed relative to the "V" in a position appropriate for the viscosity of the contents of the package.
  • the contents of the package is, for example, a high fat content cream or creamer which has a relatively high viscosity
  • the nick may be so-located as to produce a relatively large spout
  • the nick may be placed so as to produce a substantially smaller spout. It is particularly desirable to control the size of the spout out of which the contents of the package maybe poured so that the rate of pour is controlled and thus the danger of spillage or splashing is avoided.
  • the package may be provided with a number of nicks at different positions longitudinally relative to the "V" which allow the user of the package to determine the size of spout they wish to create to enable them to pour out the contents of the package.
  • the film used in the present invention is most preferably printed with indica as to package contents, origin etc prior to the use of the film in the present invention.

  • Figure 4 shows a second detail of the embodiment of Figure 3.
  • a roll (2) of plastics film (4) feeds the film (4) into a die (6).
  • the die (6) is so configured as to cause the lateral or side edges (10,12) of the plastics film to abut or over lie each other with both of the side edges (10,12) forming a common edge (8).
  • the abutment of the lateral edges causes the film (4) to form a substantially tubular structure (14).
  • the abutting edges (10,12) of the film (4) then pass between a pair of heated rollers (16,18).
  • the rollers (16,18) are impelled toward each other and heated to an appropriate temperature so as to cause the film in the region of the lateral (10,12) edges to fuse.
  • the appropriate temperature for the heated rollers will primarily be determined by the exact nature of the plastics film 4.

  • the jaws of the crimping means (22) are applied to the outside face of the tube (14) across the whole of the tube (14).
  • the jaws of the crimping means (22) are heated to an appropriate temperature so as to cause the layers of the film (4) between the jaws of the crimping means (22) to fuse with each other. This creates a first sealed portion (24) extending across the tube (14).
  • a milk supply line (26) introduces milk (not shown) into the tube (14) from a reservoir (28).

  • a pair of shears (34) cut through the tube (14) adjacent to the longitudinal edge of first sealed portion (24) remote from the second sealed portion (32).
  • the action of the shears simultaneously causes the separation of the filled package from the as yet unfilled tube (14), and causes the creation of a new open mouth of tube (14) which can be advanced to the filling position (20).
  • the dimensions of the film (4) and the distance between the first and second sealed portion (24, 32) are such that the volume of milk contained within the package created is approximately 12 mis, approximately 14 mis, or approximately 20 mis.
  • the method of manufacture described above results in a package of milk (36) which is flexible and which is manufactured using only three sealed or fused portions (8,24,32).
  • the sealed portion (24) and or portion (32) may have a nick (38) cut into them.

Abstract

L'invention concerne un procédé d'emballage du lait ou de produits laitiers sous une forme liquide et un emballage destiné à de tels produits. Le procédé permettant de créer de tels produits comprend les étapes consistant: (1) à prendre le lait brut et à normaliser celui-ci au niveau de la teneur en matière grasse, à réguler la teneur en matière grasse du lait liquide à un niveau prédéterminé et à stériliser le lait; et (2) à emballer le lait stérilisé dans un emballage aseptique (36). L'emballage (36) est une enveloppe souple constituée d'un seul morceau de film souple dont les deux premiers bords opposés sont assemblés, de manière que le film forme sensiblement un tube, les parois d'une première partie du tube (24) étant assemblées de manière à créer un récipient à goulot ouvert et, une fois le lait stérilisé introduit dans le récipient, les parois d'une seconde partie du tube (32) étant assemblées de manière à créer une enveloppe dans laquelle le lait stérilisé est renfermé.
