  • Fig. 2 is a schematic front view illustration of another mixing pack, having additional inner containers in accordance with another exemplary embodiment of the disclosure
  • the disclosure generally relates to a device and method for storing substances separated from each other and mixing them a short period before they are used.
  • Fig. 1 is a schematic front view illustration of a pack for storing and mixing a plurality of substances.
  • the pack includes a flexible non-permeable outer container 101 (referred to as "outer container").
  • the outer container is preferably made of a plastic polymer, as is commonly used for packing fluid substances, e.g. a polymer package storing saline for intravenous treatment.
  • the outer container may be made of any non-permeable material including laminated cardboard, thin aluminum sheet etc.
  • Outer container 101 defines an internal space 106 (referred to as “main internal space”). As shown in Fig.l, main internal space 106 contains substance 104 (referred to as "first substance"). While in Fig. 1 the first substance is shown as located near the bottom side of outer container 101 -first substance 104 is free to drift anywhere within main internal space 106 and may be located at any place within main internal space 106. First substance 104 may be at any state, i.e. solid, liquid, or gas.
  • Fig.l further shows two flexible non-permeable inner containers 120, 140 (referred to as “inner containers”).
  • Inner containers 120 and 140 are freely located in main internal space 106. Thus, in the process of production of the mixing pack, inner containers 120 and 140 are simply inserted into main internal space 106. Inner containers 120 and 140 are thus freely located and not detached from outer container 106, and their specific location within main internal space 106 is not important and may change.
  • outer container 101 After inserting inner containers 120,140 into main internal space 106, outer container 101 is sealed. While there are many methods and processes for sealing outer container 101, it should only be noted that the sealing of the outer container 101 must guarantee that upon activating pressure on the mixing pack, outer container 101 will not be torn.
  • the functionality of the mixing pack does not depend on the locations of inner containers 120,140, thus allowing inner containers 120 and 140 to drift within internal space 106 and change their relative location with reference to outer container 101, as well as changing their relative location to one another. While Fig. 1 shows one preferred embodiment of the disclosed subject matter in which there are two inner containers, the disclosure is not limited, and any number of inner containers can be used, whether the inner containers are to be filled with the same substance or with different substances.
  • first substance 104 may be five grams of coffee powder; internal substance 129 stored in inner container 120 may be water (that may be heated by a microwave shortly before use) and internal substance 143 stored in inner container 140 may be a sugar solution of one teaspoon of sugar.
  • each of inner containers 120, 140 includes a peripheral closure section 123,143 respectively.
  • closure sections 123 and 143 are made of a plastic soldering, easy-peel closure or any other method that provides a tearable closure section (referred to as a tearable section).
  • An important feature of plastic soldering or easy-peel closure is the ability to control the resistance of the closure in a way that guarantees that a container that was sealed by plastic soldering, easy-peel or the like, will be torn at a pressure that is quite close to a predefined level, i.e.
  • the process may guarantee that the container will be torn under pressure that is in the range of 4.8 to 5.2 PSI.
  • the outer container 101 including its sealing, is designed to hold at least a pressure of ten PSI, it is guaranteed that the inner containers 120,140 will be torn before the outer container when increasing the pressure on the outer and inner containers.
  • the disclosure is not restricted to plastic soldering or easy-peel closure for the inner container closure, and that the disclosure may be implemented with any closure mechanism that guarantees the opening of the inner containers upon applying pressure exceeding a predetermined level on the inner containers.
  • Tearable sections 123 and 143 are designed to be torn in response to relatively low pressure, tearable sections 123 and 143 will be torn and enable contact between first substance 104 and internal substances 129,149 (together referred to as "all internal substances").
  • all internal substances first substance 104 and internal substances 129,149
  • a final solution is provided for use.
  • a shaking action to be performed by the user may be required.
  • the inner containers must be filled with regard to the need of tearing their tearable sections before use.
  • an inner container contains powder it must also be filled with air to enable to increase the pressure inside the inner container by squeezing the inner container by the user.
  • the inner container is containing fluid in a quantity that is close to the volume of the inner container, this will be enough for enabling the user to tear the tearable section by squeezing the pack and increasing the pressure on its inner containers.
  • the pack is designed for mixing substances that should be heated prior to their mixing, such as coffee wherein the water should be heated prior to mixing the water and the coffee powder
  • the outer container as well as the inner containers should be made of material that is appropriate for undergoing a heating process.
  • draining member 160 that serves for draining the solution produced by mixing the substances.
  • the solution may comprise a cup of coffee or a dose of liquid medicine to be taken by a patient.
  • Draining member 160 may be designed to be opened and closed multiple times, thus enabling the consumption of only a part of the final solution, thus enabling the division of the final solution into portions, to be used at different times.
  • a marking of a scale 153 located on the lower side of outer container 101.
  • the scale enables a user to measure a certain quantity of the solution and to divide the solution into multiple, equal or non equal, portions.
  • the straw member may be a simple drinking straw or any other type of needle-like device used for draining the final solution, such as needles commonly used in medical devices.
  • one of the peripheral boundaries of the outer container is designed for multiple uses, i.e. the sealing of outer container 101 is performed by using a closure mechanism 109 implemented in a technique that enables multiple openings and closures of the outer container, enabling to use the same outer container while replacing only the inner containers.
  • peripheral boundary 103D differs from peripheral boundaries 103A, 103B and 103C.
  • peripheral boundary 103D is implemented by a non-permeable plastic zipper.
  • main internal space 106 does not contain any substance prior to the mixing action. Thus, mixing is performed only between the substances located in inner containers 120,140.
  • Fig. 2 shows an outer container 101 and two inner containers 170 and 180, each of inner containers 170 and 180 stores internal substance 173 and 183, respectively, and each of inner containers 170 and 180 contains an additional inner container 174 and 184, respectively.
  • Each additional inner container is filled with fluid 177 and 187, respectively.
  • Additional inner containers 174 and 184 are designed to occupy most of the internal space of inner containers 170 and 180. As described with reference to fig.l, each of inner containers 170 and 180 has a tearable section 171 and 181 respectively, likewise, each of the additional inner containers 174 and 184 also include a tearable section 175 and 185, respectively.
  • additional inner containers 174 and 184 When the time arrives for mixing the substances contained in the mixing pack, the user has to squeeze additional inner containers 174 and 184. While these containers are filled with fluid 177 and 187 respectively, it is possible to tear their tearable sections by applying external pressure to the containers. As the additional inner containers are torn, fluids 177 and 187 will form contact with internal substances 173 and 183, respectively. At this stage a shaking action may be required by the user in order to dissolve internal substances 173 and 183 by fluids 177 and 187 respectively, to result with two interim solutions. As previously mentioned, the volume of fluid in each of additional inner containers 174 and 184 is designed to occupy most of inner containers 170 and 180.
  • the inner containers 170 and 180 will be mostly full with a fluid solution, enabling the user to squeeze and put pressure on each of inner containers 170 and 180 and tear their tearable sections 171 and 181. Tearing tearable sections 171 and 181 will enable contact between the interim solutions and first internal substance 104. Again, a shaking action may be required in order to enable a sufficient dissolving and mixing between the first internal substance and the interim solutions.
  • the shown design guarantees that tearable sections 171,181 will not be torn before tearable sections 175 and 185 since until tearing the tearable sections 175 and 185 the pressure on tearable sections 171 and 181 can not be increased.
  • tearable sections 171 or 181 is implemented using a melting material, wherein upon tearing additional inner containers 174 and 184, the fluid 177 that is stored in the additional inner container 174 will cause the melting of inner container 170. Likewise, fluid 187 stored in additional inner container 184 will cause the melting of inner container 180.
  • the tearable section as previously defined includes the embodiment wherein all or part of an additional inner container is made of melting material. Structure and acts described herein are replaceable by equivalents, which perform the same function, even if the structure or acts are different, as known in the art. Therefore, only the elements and limitations as used in the claims limit the scope of the disclosure. When used in the following claims, the terms “comprise”, “include”, “have” and their conjugates mean “including but not limited to”.
