Definitions

• This invention relates to the nursing of infants.
• milk For the first six months of a baby's life, its sole source of nourishment is milk. This can be: - breast milk exclusively; - breast milk complimented with an artificial formula; or - an artificial formula exclusively; After six months, other foods may be introduced, but milk still forms a major part of a child's diet for at least a further year.
• the equipment can either be immersed in a chemical sterilising solution for one hour, or may alternatively be placed in a suitable container, covered with water, brought to the boil and allowed to boil continuously in the water for ten minutes and then cooled. Great care must then be taken to ensure that all sterilised objects remain sterile. Instructioas ⁇ s ⁇ rp"pli « -with all -dried or concentrated infant formulae require the water which is to be added to reconstitute the formula to T)e boiled for at least ten minutes. The water will then take an hour or so to cool to body temperature.
• the powder or concentrate itself is kept in a sterile container which is usually fitted with a plastic lid which must itself be kept sterile.
• the invention provides an infants' feeding system including a bag (10) containing a feeding formula (20) said bag (10) having been filled in sterile conditions, said filled bag (10) having only a first portion (12) thereof occupied by said formula (20), a second portion (14) of which is collapsed due to the withdrawal of air therefrom, said second portion being capable of being inserted into a rigid container (16) such that the formula (20) may be caused to flow into said second portion (14) located within said container (16).
• the invention also provides a method of producing a flexible container containing infants' formula (20), including the steps of partially filling an open-ended flexible container, partially filling said container with infants' formula (20), evacuating air from the remainder of said container to provide a collapsed portion thereof, and sealing said open end.
• the invention further provides a sealed bag (10) containing infants' formula (20) and including a collapsed portion (14) for insertion into a container (16).
• a sealed bag (10) containing infants' formula (20) and including a collapsed portion (14) for insertion into a container (16).
• FIG 1 is a perspective view of a bag filled with infant feeding formula
• Figure 2 is an elevation of a nursing bottle into which one end of the bag of Figure 1 is being located
• Figure 3 is an elevation of the nursing bottle of Figure 2 showing the liquid in the bag being transferred to the portion of the bag located in the bottle
• Figure 4 is an elevation of the bottle and bag of Figure 3, showing the bag about to be cut
• Figure 5 is an elevation of a nursing bottle ready for use.
• an artificial infants' feeding formula is prepared in sterile conditions and is packed in a disposable bag 10 (Figure 1) which preferably has the dimensions 180mm (circumference) by 330mm (length). It is considered that as most plastics materials are 1 highly permeable to oxygen they would be unsuitable for use
• 11 is to use a plastic material with a minimum permeability.
• Steps 1 and 4 will require a relatively simple plant.
• Step 2 will require the use of a UHT sterilising machine
• 37 degree of reliability in the manufacturing process is 8 essential. A one-in-five thousand failure rate, although possibly acceptable for UHT household milk, is not good enough. Either an aseptic packaging machine will be required for this particular application or alternatively, an existing machine with a high degree of reliability will need to be adapted.
• the "Intasept" aseptic 2-30 litre filler manufactured by Wrightcel Limited is claimed to have a high degree of reliability and can be very easily adapted to this application with a minimum of cost.
• the feed only occupies bottom section 12 of bag 10 and the remainder 14 of the bag has the air evacuated therefrom. Immediately after filling, the bag is sealed by conventional means to prevent any contamination. The size of the feed packaged in this way would depend upon the age of the baby.
• FIG. 1 Figures 2 to 5 inclusive demonstrate the manner in which a feed is prepared after a filed bag 10 has been purchased by a parent. The parent would obtain a filled bag 10 from a cupboard or other storage area. As shown in Figure 1, the parent would then insert the collapsed end 14 of bag 10 into the open end 18 of a conventional nursing bottle 16.
• the parent then raises filled end 12 of the bag 10 ( Figure 3) so that the infants' formula 20 flows in the direction of the arrows to end 14, which is located in bottle 16.
• the formula 20 is then within the bottle 16, but is separated therefrom by the material from which bag 10 is formed.
• the former bottom portion 12 of the bag 10 which now protrudes above the neck 18 of the bottle 16 is now substantially devoid of milk, and the outer portion of thi is cut off with scissors or the like 22 to form an open ended bag leaving, preferably at least sixty millimitres o the bag 10 -p ⁇ ot ⁇ uding above the neck of the bottle (Figur 3).
