Definitions

  • the present invention relates to an assembly for infusing a substance into a liquid, such as infusing tea into hot water.
  • the invention has particular application as a single use, disposable assembly and is herein described in that context. However, it is to be appreciated that the invention is not limited to that use.
  • Tea bags are convenient for infusing tea into hot water, but however come with a number of disadvantages.
  • the tea bag has to be jiggled up and down in order to infuse the hot water with tea effectively. Also, a separate stirrer is required in order to distribute the flavour evenly into the hot water or add other flavours such as sugar and milk. Further, the tea bags usually retain an amount of water ( therein which drips when the bag is removed from a cup.
  • Stick TeaTM (www. sticktea. com)
  • a disposable tea infuser comprising an elongated tea housing made from thin aluminium sheet.
  • the elongated aluminium housing includes a number of infusion holes along its length with the tea leaves housed within the housing.
  • the stick tea is dipped into hot water to infuse the hot water with tea and the housing itself can be used for stirring.
  • the Stick Tea infuser combines the operations of the infusion assembly and stirrer, it is expensive to manufacture and the foil housing inhibits the diffusion rate of the tea as compared to conventional tea bags.
  • the present invention provides an infusion assembly comprising: a holder incorporating a plurality of arms; and an infusion bag mounted to the holder, the infusion bag being disposed between the arms and containing a substance to be infused or dissolved in a liquid; wherein the arms are arranged to adopt an open condition where the arms are spaced apart and a closed condition where the arms are arranged to squeeze the infusion bag.
  • An infusion assembly has a separate holder which is able to adopt various conditions relative to the infusion bag. This in turn improves the functionality of the device. For example, when the holder is in its fully open condition, the holder can have minimal influence on the infusion rate of the substance through the bag. When moved to its closed condition, the holder can be used to squeeze the bag.
  • the arms are arranged to pivot relative to one another and to the infusion bag about an upper end of the arms so as to move between the open and closed conditions.
  • the arms are elongate and can be sufficiently rigid to allow the assembly to be self supporting so that it can stand on the lower ends of the arms and/or may be used as a stirrer.
  • the infusion bag and a lower region of the arms are arranged to be immersed below the surface of the liquid.
  • the arms are made from sheet material so as to incorporate a generally planar side wall that extends between upper and lower ends of the arms .
  • at least two of the arms are integrally formed together.
  • the arms may be provided with a plurality of openings formed in the side wall of the arms. In an arrangement where the arms include a plurality of openings, these openings are located in a lower region of each arm.
  • the arms may be made from material having substantially smaller surface area, such as wire of the like, which are sufficiently spaced apart to obviate the need for infusion openings.
  • the infusion bag is connected directly to the holder.
  • the infusion bag is mounted to an inner side of at least one of the arms.
  • the infusion bag is mounted to the holder through a connector so as to space the infusion bag from the holder.
  • the connector may be formed from any suitable material.
  • the connector may be formed of string or may be an extension of the porous material used to form the infusion bag.
  • the connector extends from an upper end of the arms so as to be disposed between the arms in the open and closed condition.
  • the infusion bag is elongate.
  • the assembly can adopt a generally elongate configuration when the arms are similarly formed in an elongate fashion and when disposed in their closed orientation.
  • This elongate shape facilitates use of the assembly as a stirrer, its location in a broad range of vessels (e.g. tea cups and the like) and also is ideally suited for packaging as it is relatively compact.
  • the assembly may incorporate a single infusion bag or multiple bags if desired.
  • An advantage of using multiple bags is that it can further improve the efficacy of the assembly to infuse by increasing the effective surface area of the bags.
  • the multiple bags may incorporate different substances which in turn can be infused at different rates or for differing length of times.
  • At least two of the plurality of infusion bags are interconnected by the connector.
  • At least one of the arms incorporate a cavity which is able to contain a substance and which is arranged to be released into the liquid under predetermined conditions.
  • this substance may be the same as the substance in the infusion bag, in one form, it is a separate substance.
  • the substance contained in the cavity may include milk, sugar, whitener, etc.
  • the predetermined conditions is selected from a threshold temperature and/or a threshold pressure being applied to the arms. This arrangement has the advantage that the release of the substance from the cavity can be controlled and/or delayed until after the primary infusion has taken place.
  • the infusion assembly further comprises an actuator operative to move the arms together to adopt the closed condition.
  • the actuator may be used to squeeze the bag after use, and/or may be used to reduce or stop the infusion process by moving the holder to it closed condition.
  • the use of an actuator is particularly suited in arrangements where at least part of the holder is immersed in the liquid.
  • the actuator is in the form of a sleeve which is disposed about the holder and slideable towards a lower end of the holder.
  • actuator can be imprinted with advertising.
  • the present invention provides an infusion assembly comprising: a holder having an upper end and a lower end and at least one side wall disposed between the ends, a cavity associated with the holder, the cavity containing a substance to be infused or dissolved in a liquid, wherein the holder is arranged to adopt an open condition where the cavity is open and a closed condition where the cavity is caused to collapse, and an actuator operative to cause the holder to adopt the closed condition so as to squeeze the substance in the cavity.
  • the holder may take other forms in addition to the arrangement of holder with the plurality of arms as disclosed above.
  • the holder may be arranged as a substantially cylindrical housing that entirely encases an infusion bag or defines the cavity.
  • the cavity is disposed within the holder. In another form the cavity is formed in an infusion bag connected to the holder.
  • the assembly in any form described above, is disposable and arranged for single use. Furthermore, in another embodiment the assembly is encased a hygienic wrapper.
  • the substance contained by the infusion bag comprises tea leaves, herbs, dried fruit or like material .
  • the present invention provides a holder for use with an infusion assembly.
  • the holder may be for multiple use and the infusion bag is connected to the holder immediately prior to use. After use, the infusion bag can discarded.
  • the holder can be made from recyclable material, such as plastics or corrugated paper. All of the components of the assembly can be made from recyclable or biodegradable material .
