Description

A POUCH FOR CONTAINING A BEVERAGE
The invention relates to a pouch for containing a beverage. The pouch is intended to contain a beverage for the duration that the beverage is being consumed. In other words, it is intended that a user drinks a beverage directly from the pouch.
An aim of the present invention is to provide an improved pouch for containing a beverage and/or an improved method of making a pouch for containing a beverage.
A different aim of the present invention is to provide an alternative pouch for containing a beverage and/or an alternative method of making a pouch for containing a beverage.
According to a first embodiment of the invention there is provided a pouch for containing a beverage in accordance with Claim 1.
According to a second embodiment of the invention there is provided method in accordance with Claim 5 of making a pouch for containing a beverage.
Other optional and preferred features of the invention are set out in the dependent claims, and the description, below. The features of one aspect of the invention can be combined in any complimentary manner, with one or more features of another aspect of the invention, the dependent claims, and/or with one or more features of the description, where such a combination of features would provide a working embodiment of the invention. An embodiment of a pouch for containing a beverage, and a method of making a pouch 50, both in accordance with the invention, will now be described, by way of example only, with reference to the accompanying drawings, in which,
Figure 1 is a side view of a roll of material used to make a pouch for containing a beverage in accordance with an embodiment of the invention,
Figure 2 is a perspective view of the roll of material of Figure 1, and a length of material being formed, and a close up of part of the length of material,
Figure 3 is a perspective view of a pouch in accordance with an embodiment of the invention,
Figure 4 is a front view of the pouch of Figure 3,
Figure 5 is a side view of the pouch of Figure 4,
Figure 6 is a view from above of the pouch of Figure 4, and
Figure 7 is a view from below of the pouch of Figure 4.
Referring to Figure 1, a roll of material 10, with an axis of rotation 11, has a length of material 12 pulled off of it. The roll of material may be pre printed. The length of material 12 is a laminate. The laminated length of material 12 is made from a flexible metal-plastic laminate which is able to withstand thermal processing used for sterilisation.
In one embodiment, the laminated length of material 12 comprises, from inside to outside:
1. a layer of polyethylene (known by the abbreviation PE),
2. a first layer of Polyethylene terephthalate (known by the abbreviation PET),
3. a second layer of Polyethylene terephthalate (PET), and
The two layers of PET provide greater rigidity and a better Oxygen barrier. One layer of PET of double the thickness is not used because it is not sufficiently mouldable.
There is optionally a metallised ink on the outer surface of the second layer. Alternatively, the outer surface of the second layer may be covered by a coloured ink. Optionally, the pouch may have no ink to remain clear.
For example, for a pouch containing milk, a laminate may contain a paper barrier between the PE inner layer and the first PET layer. In that way, better resistance to UV is provided, and a better Oxygen barrier is provided.
For pouches containing liquids with a longer shelf life still, a laminate may include the PE layer, the first PET layer, the second PET layer, and two layers of paper, and an alufoil layer. Other layers can be included in a laminate, and one or more of thee layers can be removed. Numerous permutations of sequences of layers are possible in accordance with the invention.
For any laminate, PE must always be the inner layer, so that the parts A and B of the laminate can be adhered to one another.
The laminate length of material 12 is placed on a form, fill and fill machine (not shown) and a pouch (see Figures 3 to 7) is formed, cut, filled, then sealed.
The laminated length of material has part A and part B. Each part A and part B will cooperate to form a finished pouch.
Referring to Figure 2, after the length of material 12 is unwound or pulled off the roll 10, Part A (hidden behind part B) is folded at point 13 against part B. The PE inner layer will be adjacent the beverage, as described above.
Between successive parts B, the laminated length of material 12 is pressed together and the touching parts A and B are sealed at periphery 14 of pouch.
The sealed periphery 14 defines a receptacle 16 region inside.
Referring to Figure 2, between successive parts B, the laminated length of material 12 is cut to form pouch units 50. Each part B corresponds to a pouch 50 as shown in Figures 3 to 7. The fruit juice is first prepared, even raw or cooked, and then sealed into the pouch 50. The pouch 50 is then heated to 240 - 250 degrees fahrenheit (116 - 121 degrees celcius) for several minutes under high pressure, inside pouch or autoclave machine. The juice inside the pouch is cooked, similar to pressure cooking. The process reliably kills all commonly occurring microorganisms (particularly Clostridium botulinum), preventing it from spoiling.
The pouches 50 can be filled then cut between them or cut between them and then filled.
Each receptacle 16 region is dosed with liquid Nitrogen, using a liquid Nitrogen doser. Liquid Nitrogen is the only known workable food grade compound. The amount of liquid Nitrogen depends on the pouch size, pouch beverage fill level, the type of beverage, and the temperature of the beverage, but can be between 0.3 grams and 3 grams.
Then the pouch is sealed, then cooled, so that the liquid Nitrogen changes state and gaseous Nitrogen expands to fills the receptacle 16, applying pressure to the receptacle, and making the pouch appears (more) full, and (more) bottle shaped.
Referring to Figures 3, 4, 5 and 7, the pouch has a base 22.
The pouch has a body region 24, ending approximately at shoulders 26, and a narrowing neck 28.
Referring to Figures 3 to 4, at the top of the neck 28, the pouch 50 has an in-built tubular region 20 which functions like a straw. The in-built tubular region 20 is in liquid communication with the receptacle 16. At the top of the neck 28, the pouch 50 has a wider seal 30, at least 0.75 cm wide. The wider seal 30 has a space which allows the integrated straw or spout 20 to passes through it.
Above in-built tubular region 20 is a tubular region end seal 35.
The seal has a mechanically punched section, to provide a line of weakness 22 at which the user can tear the pouch open.
The sealed periphery 14, and the tubular region end seal 35 are at least approximately 3 mm deep, and varies in depth from approximately 3 mm to approximately 6 mm. The sealed periphery 14 is sealed by conventional means known to the industry.
When the pouch 50 is filled with a drink and gaseous Nitrogen (from the liquid Nitrogen dose), the liquid Nitrogen the pouch 50 becomes bottle shaped. The pouch 50 can stand on its base 18 when unopened. The pouch 50 remains upstanding even when the receptacle 16 is only a quarter full of a beverage, preferably even when only about 5% full. The gaseous Nitrogen leaks when the pouch opens, but the shape and dimensions of the pouch enable it to still stand.
Referring to Figure 5, facing the plane of the coincidence region (or sealed region), the inclination of a hypothetical straight line from the periphery 32 of the base 16 to the top of the neck 28 is approximately 70 to 80 degrees to the horizontal. The actual initial inclination of the line 31 of the outside of the pouch is above 70 to 80 degrees, and line 31 of the outside of the pouch is concave with respect to the liquid inside it. An advantage of the in-built tubular region 20 is that no straw is required. In use, a user can tear off the material above line of weakness 22, leaving in-built tubular region 20 in liquid communication with the atmosphere, so that the user can drink the beverage contained in the pouch.
The pouch 50 in accordance with the invention is an alternative to plastic bottles, cheaper to make, lighter, more transportable, and easier to store, and less voluminous after use.
The pouch 50 can revert to a flat configuration when empty, thereby reducing waste management space requirements by about 95% - from the waste bin, on the route to a dump site, and at the dump site - compared to PET bottles.
