The invention is now described, by way of non-limiting examples, with reference to the accompanying diagrammatic drawings.
In the drawings:
Figure 1 shows, schematically, a face-on elevation of a container in accordance with the invention;
Figure 2 shows, schematically, a face-on elevation of another embodiment of a container in accordance with the invention;
Figure 3 shows, schematically, a further embodiment of a container in accordance with the invention; and
Figure 4 shows, schematically, a face-on elevation of yet another embodiment of a container in accordance with the invention.
With reference to Figure 1 of the drawings, a container in accordance with the invention for containing a consumable fermentable liquid is generally designated by reference numeral 10. The container 10 includes an elongated body 12 of synthetic plastics material. The container 10 is intended to contain a consumable fermentable liquid, which need to ferment, which goes hand in hand with formation and release of gas, before it is to be consumed.
The body 12 of the container 10 has an operatively lower end 14, and an operatively upper end 16. The body 12 is manufactured from two elongated rectangular sheets of liquid impervious synthetic plastics which are laid one on top of the other in face-to-face relationship, with elongated side edges of the two sheets of synthetic plastics being thermally secured together. Further, lower edges of the sheets of synthetic plastics are also thermally secured together. A transverse seal 19 is provided adjacent the upper end 16 of the body 12 and secures the two sheets together. The body 12, as further described hereunder, is divided to form a primary compartment 18 for receipt of a fermentable liquid (not shown in any of the drawings) and a secondary compartment 20 operatively above the primary compartment 18. In particular, the primary compartment 18 is separated from the secondary compartment 20 by means of
® a transversely extending thermally formed seal 22, the seal 22 being interrupted to define an elongated venting passage 24 which is generally in the form of a flue or a chimney vent. In this embodiment, the venting passage 24 is more or less normal to the length of the seal 22.
Venting openings 26, the purpose of which will become more apparent : hereunder, are provided in an upper part of at least one wall of the body 12 defining the secondary compartment 20. At its upper end, the body 12 is provided with a longitudinal extension 28, which is provided with an elongated transversely extending handle opening 30. The extension 28 and the handle opening 30 together define a carry handle for carrying of the container 10 when its primary compartment 18 contains fermentable liquid. in use a fermentable consumable liquid is, prior to fermentation thereof, received in the primary compartment 18 of the container 10. The fermentable liquid is typically received in the primary compartment 18 during manufacturing of the container 10. During fermentation of the fermentable liquid in the primary compartment 18, gas is : formed and released by the fermentable liquid, which causes a rise in pressure in the interior of the primary compartment 18. The construction of the body 12 is such that, upon sufficient build-up of pressure in the primary compartment 18, the venting passage 24 is forced open, i.e. the two sheets of plastics are forced away from each other along the venting passage 24, to permit release or venting of formed gas from the primary "compartment 18 into the secondary compartment 20. Because of the particular construction of the body 12, the venting passage 24 is, as foreshadowed above, substantially closed during low pressure conditions in the primary compartment 18. Gas vented into the secondary compartment 20 can escape to the atmosphere via the venting openings 26.
When the container 10 is placed in an operatively upright condition, with fermentable liquid contained in its primary compartment 18, no or little liquid from the primary compartment 18 will escape into the secondary compartment 20. Even if liquid
® escapes into the secondary compartment 20, flow of such liquid from the secondary compartment 20 via the ventilation or venting openings 26 is, by virtue of the positioning of the openings 26, resisted. Thus, whilst providing for release or venting of formed gas from the primary compartment 18, leakage of fermentable liquid from the container 10 is resisted when the container 10 is transported or stored in an operatively upright condition.
In order to drink or pour fermented liquid contained in the primary compartment 18, an opening which leads into the primary compartment 18 can be made in an upper part of the body 12. If desired, the body 12 may be provided with an area or zone of weakness along which the body 12 can be torn to provide such an opening.
Even further, if desired, the body may be provided with a spout formation for facilitating drinking or pouring of fermentable liquid contained in the primary compartment 18.
Referring now to Figure 2 of the drawings, another embodiment of a container in accordance with the invention is generally designated by reference numeral 40. The container 40, in most respects, resembles the container 10 and, accordingly unless otherwise indicated, reference numerals used to indicate parts or features of the container 10 are also used to indicate like parts or features of the container 40.
With the exception of the omission of the extension 28 and, accordingly the carry handle, the container 40 is exactly similar to the container 10 and is not described in further detail.
Figure 3 of the drawings shows a further embodiment of a container in accordance with the invention. The container 50, in certain respects, resembles the container 10 and, accordingly unless otherwise indicated, reference numerals used to indicate parts or features of the container 10 are also used to indicate like parts or features of the container 50.
®
In this embodiment, the secondary compartment 20 provided by the container 10 is omitted, such that the body 12 of the container 50 defines only a primary - compartment 18, with the venting passage 24 opening into the atmosphere. In use, gas formed in the primary compartment is thus vented or escapes from the primary compartment directly into the atmosphere.
Referring now to Figure 4 of the drawings, a yet further embodiment of a container in accordance with the invention is generally designated by reference numeral 60. The container 60, in certain respects, resembles the container 10 and, accordingly unless otherwise indicated, reference numerals used to indicate parts or features of the container 10 are also used to indicate like parts or features of the container 60.
In this embodiment, the extension 28 provided by the container 10 is also omitted. A further difference between the container 10 and the container 60 is that the venting passage 24 of the container 60 is somewhat torturous, in that it extends, along part of its length, transverse to the length of the body 12, i.e. substantially parallel to the seal 22. Naturally, if required, the container 60 can be provided with the extension 28 and a handle opening 30 provided therein. The same applies to the container 50.
The invention as described and illustrated thus provides a flexible synthetic plastics container for containing fermentable liquid, which container provides for venting of gas formed during fermentation of the liquid, but resists leakage of fluid * from the container when the container is in an upright condition.
