Abstract

An additive container for an additive potable liquid; said additive container adapted for screwed connection to a standard screw-top base potable liquid container; said additive container provided with sealing means adapted to change from a first sealed state to a second unsealed state by contra-rotation of said additive container relative to said base potable liquid container.

Description

  • The present invention relates to methods and apparatus for the mixing of the contents of a first with those of a second container and, more particularly for the mixing of one predetermined volume of a substance with a second predetermined volume.
  • BACKGROUND
  • Many liquids, whether they be for drinking, cleaning or some other application may be made up of a base liquid and an additive liquid. Frequently it is the case that such an additive liquid is of a concentrate requiring dilution with a base liquid.
  • An example for potable liquids is found in cordials where a strongly flavoured concentrate is added to water to give an acceptable drink. Another example of such mixing is where a relatively small volume of alcoholic beverage is added to a larger non-alcoholic volume of a proprietary drink.
  • Often the concentrate is supplied in a relatively large volume container from which smaller volumes may be decanted for addition to the water or some other base liquid to which it the concentrate is to be added. In the case of drinks, these are frequently consumed in situations or venues where the transporting of a large container and the decanting is inconvenient or undesirable. Especially, if it is desired to have a choice of various flavours or alcoholic additives, the multiple large containers required become impractical.
  • The optimum mixture of a concentrate additive and a base liquid is often determined by a particular narrowly defined ratio of the concentrate to the base liquid. Thus, without careful measuring, a desired ratio is difficult to achieve resulting in an unsatisfactory mixture.
  • Similar problems are encountered in situations where a particular volume of a substance in granular or powder form needs to be added to a base liquid.
  • It is an object of the present invention to address or at least ameliorate some of the above disadvantages.

  • DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS First Preferred Embodiment
  • With reference to FIG. 1, in a first preferred embodiment of a system for combining liquids according to the invention, an additive liquid container 10 is provided in the form of a relatively small bottle 11 having a body 11 and a neck portion 12. Small bottle 11 is provided with a pierceable seal member 19 at neck opening 21 and with piercing collar 13. In this embodiment as shown in FIG. 1, piercing collar 13 is attached to neck portion 12 by lower threaded portion 25 during manufacture.
  • Piercing collar 13 is comprised of a cylindrical housing 20 provided at upper opening 14 with internal thread 15. Internal thread 15 extends at least part way from the outer rim 27 down the bore of piercing collar 13 and is adapted for screwed connection to the external thread of standard screw-top containers such as for example PET water bottles. The internal thread 15 of piercing collar 13 may be provided in a range of sizes to suit a range of standard screw-top containers depending on the application and type of liquids to be mixed together.
  • Piercing collar 13 is further provided with piercing member 16 retained in a first sealing position as shown in FIG. 1 by a plurality of connection lugs 17 which provide breakable bridging elements between piercing member 16 and the internal surface 28 of the bore of piercing collar 13.
  • Piercing member 16 is in the form of a disc with a projection 22 and passage 24. Central projection 22 is provided with sharp edge 23 defining the opening of passage 24 adapted to pierce seal member 19. While only one projection 22 and passage 24 is shown in the illustrated embodiment of FIG. 1, more than one may be provided.
  • In at least one preferred embodiment of the invention piercing collar 13 may be provided with a protective sealing cap (not shown) which may be screwed into the threaded opening 14 and retained therein until use of the contents of additive container 10 is required.
  • In use the protective sealing cap (if provided) is removed and the additive container screwed onto a base potable liquid container 30 as shown in FIG. 2. Initially the two containers may be left in the position shown leaving the piercing member 16 undisturbed. Preferably in at least one embodiment of the invention, the outer face 18 of piercing member 16 is provided with an annular seal (not shown), which is adapted to retain liquid in the attached base liquid container 30 when in this first connected position.
  • The additive container may be formed of any suitable plastic but preferably of a plastic allowing of recycling, such as PET for example.
  • To effect a mixing of the contents of the additive potable liquid container and the base potable liquid container, the two containers are contra-rotated relative to each other causing the rim 31 of the neck 32 of base container 30 to be driven against piercing member 16 so as to break connector lugs 17. As the neck 32 of base potable liquid container 30 further advances into piercing collar 13, piercing member 16 is driven into annular space 29 as shown in FIG. 3. Sharp rim 23 is forced against seal member 19 causing the seal member 19 to rupture and allowing the contents of additive potable liquid container 11 to flow into base potable liquid container 30.
  • Second Preferred Embodiment
  • In a further preferred embodiment in which like features have been numbered alike with the addition of 100, piercing collar 113 is substantially as described in the first embodiment above, but is only internally threaded at that end 114 intended for screwed attachment to a base liquid container. In this form, as shown in FIG. 5, the other end 120 of the neck portion 112 of container 111 is attached to additive potable liquid container 111 after filling, by such means as for example a suitable adhesive, friction welding or ultrasonic welding.
  • Third Preferred Embodiment
  • In this embodiment of the invention shown in FIG. 6, an additive liquid container 211 is again provided with a pierceable seal 219. Note that in FIG. 6 the additive container 211 has been inverted and screwed to the neck of a base liquid container 233. Seal 219 may for example be affixed across the opening 221 of container 211 by ultrasonic welding or other suitable means, after the container has been filled with an additive liquid. Piercing collar 213 is preferably comprised of a first portion 214 and a second portion 215 for, but may also be formed as a single integral unit.
  • When formed as first and second portions as shown in FIG. 6, the mating ends 216 and 217 may be formed to connect together as a snap-fitting. Mating ends of the first and second collar portions may be provided with engaging lugs or castellation (not shown) so as to prevent the rotation of one collar relative to the other when in use. Alternatively the portions may be attached together by for example, heat welding or with a suitable adhesive.
  • Collar 113 is attached to the additive container after this has been filled with its contents. In at least one preferred form as shown in FIG. 6 the lower portion 214 of the collar is provide with an internal thread 220 adapted to mate with the external thread 221 at the neck portion 222 of the additive container 211.
  • The second portion 215 of collar 113, is provided with an internal thread 224. Second collar portion 215 may be provided in a range of threads to suit standard threads employed on the necks of containers of base liquids for which the additive liquid is intended.
  • Second portion 215 of collar 113 is further provided with piercing insert 226. In this embodiment piercing insert 226 is in the form of a tubular member 227 retained within the bore 228 of second portion 215 by a series of radially disposed friable lugs 229.
  • Preferably, the lugs 229 extend radially outwardly from an annular ring 230 to the inside surface of the bore 228 of second portion 215. The ring 230 extends radially outwardly sufficient to allow contact with the rim 232 of the neck opening of a base liquid container 233 when this is screwed into the thread of the second portion 215.
  • Alternatively, the lugs 229 are so formed that the friable portion lies adjacent to the inside surface of the bore 228 of second portion 215 so that a sufficient portion of the lugs 229 remains intact to provide contact points for the rim 232 of the base liquid container 233.
  • Tubular member 227 is adapted to slide into the bore 234 of a base liquid container 233 when the additive container 211 is first screwed to the threaded neck portion of base liquid container 233.
  • Initially, the base liquid container 233 is screwed into the second portion 215 of collar 213 until the rim 232 of the neck of the container 233 is in contact with the annular ring 230 or the friable lugs 229. With sufficient force, base liquid container 233 may be further screwed into second portion 215 so as to break the friable lugs 229, thus driving the tubular member 227 into contact with the pierceable seal 219.
  • The inner rim 235 of tubular member 227, that is the rim oriented towards the seal 219, is provided with a sharp edge and may be angled so that the sharpened edge gradually pierces the seal 219.
  • In use, a base liquid container 233 is positioned with its neck uppermost and its sealing closure removed as shown in FIG. 6. The additive container 211 is then inverted and screwed down onto the base liquid container until the seal 219 is pierced, thus allowing the contents of the additive container to flow into the base liquid container 233 and the contents of the two containers to mix together.
  • Fourth Preferred Embodiment
  • In yet a further preferred form of the invention, the piercing collar is substantially as described in the above embodiments, that is as a single integral item or as first and second portions attached together. However in this embodiment, as shown in FIG. 7, the collar is not attached to an additive container at manufacture but may be supplied as a separate item available for use in the transfer of contents from any suitable first container to a suitable second container.
  • The first portion 314 of collar 313 of this preferred embodiment is provided with a pierceable seal 319, so that when the first collar 314 is screwed to the neck of a first container, the pierceable seal 319 provides a closure for that container.
  • In the embodiment shown in FIG. 7, where the collar is manufactured in first and second portions 314 and 315 respectively, which may be snap-fitted together, first and second portions may be provided in a variety of sizes and threads such that a selection of appropriate first and second portions may be made to connect the collar to containers having different neck openings and threads.
  • EXAMPLES OF APPLICATIONS
  • Any one of the above described embodiments may be applied for the mixing of one liquid with another. Additive potable liquids may include any one of a range of liquids including for example cordial concentrates, milk flavouring additives and alcoholic beverages.
  • A number of additive potable liquid containers provided with various selections of flavour concentrates or alcoholic beverages may be arranged together in a convenient carry pack. Such a pack of selected additive potable liquids may be taken to a venue such as a party, picnic or some other function where either bottled water, milk or proprietary beverages are readily available thus obviating the need to carry a selection of such additive potable liquids in large containers.
  • In at least one preferred embodiment of the invention, information is provided on the additive potable liquid container, or on a label affixed to the container, or printed on the carry pack, as to what volume of base potable liquid the additive potable liquid is suited for so as to give a satisfactory mix. In the case of alcoholic additives, such information may include a range of suggestions of proprietary beverages and volumes of such beverages for which the selection of additive potable liquids is suited. Thus for example a particular liqueur in a given volume additive potable liquid container may provide a desirable mix with one proprietary beverage in a 750 ml bottle but be better suited to a 375 ml bottle of another beverage.
  • The above describes only some embodiments of the present invention and modifications, obvious to those skilled in the art, can be made thereto without departing from the scope and spirit of the present invention. Thus for example while the above described embodiments are in the main directed at drinking liquids, the invention may equally be adapted to the mixing prior to use of any two liquids to form chemical compositions for a wide range of applications.
  • Neither is it intended that the invention be limited to the mixing of two liquids so that the contents of the additive container may be in powder or granular form for example, for addition to a liquid.
