Definitions

  • the desired end products are prepared by mixing the precursors with additional liquids, often water or alcohol.
  • Reference to "concentrated liquids or solids" in this application means liquids or solids having less liquids than the hydrated, rehydrated, reconstituted or desired products.
  • the hydrated, rehydrated, reconstituted or desired products are the end products for use or consumption.
  • the concentrated liquids or solids can be produced by a dehydration process from the hydrated products or from precursors.
  • the rehydration process in this invention refers to any processes where a liquid is added to a concentrated liquid or solid.
  • the rehydration process can be carried out at a central location near consumers, such as at a local bottling company, at a restaurant, or at other consuming sites, such as a consumer's home, a camping ground, a hospital room or a research laboratory.
  • the rehydration process usually involves measuring the correct amount of concentrated liquid or solid and the correct amount of the diluting liquid, then mixing them together in a suitable container. If the amount of hydrated product is large, it may need to be divided into smaller sized containers for consumption and/or storage for future consumption.
  • a measuring cup may be hard to locate when a crying baby wants formula or a patient urgently requires medicine.
  • the accuracy of the measurement can be a problem in many circumstances.
  • inadvertent spills of concentrated liquid or solid powder when pouring from bottles into cups or other mixing containers may be messy.
  • Various devices have been developed in an attempt to address the different aspects of the rehydration process. For example, small amounts of instant coffee powder are packaged in packets for a certain sized cup. For consumption, the packet is opened and then the coffee powder is poured into a cup.
  • a disposable cup has been used as the package for the concentrated liquid or solid, so no additional cup is necessary. Water is added to the cup to produce the desired product. But the cup typically significantly increases the volume of the package for the concentrated liquid or solid because the cup must have sufficient volume to accommodate the end product. The relatively large volume or size of the cup reduces the benefit of using a concentrated liquid or solid.
  • the package for concentrated liquids or solids can be composed of a flexible material and function as an insert for another container serving as a shell.
  • the flexible package is placed in the shell container.
  • the package is opened and water or other diluting liquid is added to the package.
  • the shell container provides support and protection for the end product.
  • the forgoing packaging materials are typically composed of paper, plastic, or a combination thereof.
  • Paper is a natural product and environmental friendly. But paper is usually not very strong. Also, it is a poor liquid or vapor barrier.
  • Plastic such as polyolefin, is durable, strong, and a good barrier for liquid or vapor. But plastic can be very slow to decompose, thereby accumulating in landfills and causing environmental problems.
  • the present invention advantageously provides a package for concentrated liquids or solids and the rehydrated products thereof.

  • FIGURE 2 is a plane view of a flat sheet 50 that can be used to construct the container 20 shown in Figure 1, where the panels have not yet been folded and the margins thereof have not yet been sealed.
  • FIGURES 3 and 4 show another embodiment of the present invention in the form of a container 30.
  • the container 30 is essentially constructed from a flat sheet 40.
  • the flat sheet 40 is generally rectangular in shape, and thus has a top, a bottom and two sides.

  • the flat sheet 40 also has a fold line 31 extending along longitudinally between two panels 41 and 42 comprising the sheet.
  • the container When the concentrated liquid or solid alone is stored in container 30, the container is essentially flat. It can be rolled or folded further to reduce its size if the sheet material is sufficiently flexible. When the diluting liquid is added to the container 30, the container expands and becomes generally pillow-shaped, as shown in FIGURE 3. Designed with a spout, this type of container can conveniently be used as a portion pack that can easily be carried about, e.g., in a person's pocket or handbag.

  • Panel 200 also has a right margin 222 opposite left margin 124, a top section and a bottom section.
  • the top and bottom sections of panel 200 are mirror images of the top and bottom sections of panel 100. Similar to the left panel 100, the top section of the right side panel 200 has sequential margin segments 202, 203, 204, 206, 208, 212, 214 and 216. Also, the bottom section of the right side panel has sequential lower margin segments 242, 244 and 246.

  • the margin segments 206, 208 and 212 cooperatively define an upwardly extending protrusion or spout section 210.
  • the margin segment 103 together with the corresponding margin segment 203 on the right shoulder of the right side panel 200 can conveniently form a side spout.
  • the left side panel 100 also has an oblong hole 156, outwardly adjacent and extending along margin segment 116.

  • the flat sheet 50 and the container 20 can be advantageously constructed by a continuous process, as shown in Figures 5-10.
  • the flat sheet 50 can be eventually cut from an endless sheet material.
  • a roll of such endless sheet material is shown in Figure 5.
  • the endless sheet can be folded along the longitudinal axis to form a W-shaped endless sheet, which has two outer layers and two inner layers, as shown in Figure 6.
  • the outer layers will become the two side panels 100 and 200 of the flat sheet 50 and the inner layers will become the bottom panel 300 of the flat sheet 50.
  • the first and second side panels 100 and 200 do not share a common fold line, but each of them shares a common fold line with the bottom panel 300.
  • the shared fold lines are between margin segments of 134/334 and 244/344.
  • the W-shaped endless sheet will be punched and "welded” by heat sealing or other processes into the shape of a side panel of flat sheet 50. Each individual flat sheet is still connected to each other in the W-shaped sheet, as shown in Figure 7. All the corresponding side margins are welded or otherwise sealed to form container 20, except the seals at the spouts on top of the flat sheet 50, as in Figure 1.
  • the W-shaped endless sheet is rolled back into a roll composing of many containers 20, as shown in Figure 8.
  • the roll of endless sheet of container 20 can then be used in a continuous filling machine to be filled-in with the concentrated liquids or solids, as shown in Figure 9.
  • each container 20 is filled with correct amount of concentrated liquids or solids
  • the individual container 20 is evacuated and sealed.
  • the containers 20 with concentrated liquids or solids can again form a roll as in Figure 8 for storage or transportation.
  • the containers can be cut out of the endless sheet as individual packages for storage, transportation or distribution, as shown in Figure 10.
  • the container 20 when all the margins are sealed together, except margin segments 108/208, the container 20 is ready for use.
  • the container 20, as assembled, has a nominally, substantially flat profile. When the container is assembled, access to the interior of the container 20 is through the unsealed top margin segments 108/208.
  • a nozzle from a filling machine or apparatus can be inserted into the container 20 through the opening at margin segments 108/208. Once the correct amount of concentrated liquid or solid is dispensed into the container 20, the container can be evacuated and sealed at margin segments 108/208. Removing the air from the concentrated liquid or solid can result in the contents of the container to be preserved for a relatively long period of time.
  • the container 20 can assume a relatively flat configuration and occupy minimal space when transported and/or stored.
  • the seal at line 108/208 can be cut or otherwise broken. Thereafter, the container 20 can be filled with the diluting liquid (thereby expanding the container) to produce the desired product.
  • the volume of the container 20 guarantees a correct amount of diluting liquid being filled into the container. Such guarantee of correct amount of diluting liquid is very important, especially in medical or nutrition substance applications.
  • the spout 22 can then be closed or resealed. There are numerous ways to reseal spout 22. For example, it can be resealed with a cap, a plug or similar closure item. For a more permanent closure, a heat sealing iron can be used. Also, spout 22, formed by the protrusions 110/210, can be held pressed together with a clip or pin.
  • the container 20 can be shaken and/or turned upside down, etc., to mix the concentrated liquid or solid with the diluting liquid. Once the concentrated liquid or solid and the diluting liquid are well mixed, the end product is produced and ready for use. No measuring of the concentrated liquid or solid or the diluting liquid is necessary. There is no need to transfer concentrated liquid or solid from one container to another.
  • the end product can be retained in the same container and can be sealed therein to extend the product's useful life, or maintain the freshness of the product, such as a food product.
  • the product can be dispensed directly from the container 20 through the spout 110/210 or transferred to another container.
  • the product can also be preferably dispensed through a side spout by cutting or tearing the container at margin segment 23, as shown in Figure 1.
  • the container 20 can conveniently be handled like a jug when pouring the product from the container.
  • the contents can be stored in the container 20. Due in part to the flat bottom panel 300 and/or the substantially straight, parallel margin segments 134/334 and 244/344, the container 20 can sit on a flat surface by itself without having to be placed into another container.
  • the angles formed by margin segments 332/342, 336/346 also help the ends of the bottom panel 300 to bend or extend upwardly evenly to join the adjacent margins of the panels 100 and 200, thereby leaving the rest of the container bottom 28 substantially flat and without bulges.
  • the handle 24 can be used to conveniently carry the container 20. Unlike many existing single use/single serving containers, the spout 22 can be advantageously resealed by various means to keep the contents of the container 20 fresh for an extended period of time.
  • the container 20 can be easily flattened back to its original profile.
  • the container 20 can be further folded or rolled into an even smaller size.
  • the material used to construct the container 20 may not have a "memory", so that when storing the concentrated liquid or solid, the container 20 can be rolled or folded into a smaller configuration. Also, when adding the diluting liquid, the container 20 can readily expand. Later, after the restored product has been consumed or used, the container 20 can then be returned to a collapsed, flat configuration for disposal.
  • the material used to form the flat sheets may preferably be a combination of a mineral based filler material and a plastic binding material.
  • a mineral based filler material such as calcium carbonate is blended with a binding material, such as polyolefin or other plastic material, to form a homogenous plastic composition material.
  • the plastic composition material has most of the characteristics of a plastic material, so the plastic composition material can be used in the same ways as other plastic materials are used.
  • the plastic composition material can be formed into pellets for further applications, such as thermoforming, injection molding, film blowing or sheet extrusion.
  • the plastic composition material can be made into homogenous films or sheets for packaging applications.
  • the plastic composition material can be more advantageously used with other materials to form a laminated sheet material with more desirable properties for packaging applications.
  • the laminated sheet material can have an outer heat-seal layer, a plastic composition material layer, a UV barrier layer, a second plastic composition material layer, an oxygen barrier layer and a second heat-seal layer.
  • the combined thickness of the layered material can range from 40 to 80 microns, or thinner or thicker depending on the need.
  • the mineral based filler materials are in abundant supply.
  • a large portion of the filler/binder plastic composition material consists of the mineral based filler material.
  • the mineral based filler material can be composed of calcium carbonate, which can come from chalk or dolomite or magnesium silicate which can be derived from talc or mica, or many other mineral based materials.
  • the mineral based filler/binder mixture decomposes much faster than common plastic materials. Once decomposed, the bulk of the mixture, which is the mineral filler, will return to its natural state, either in solid form such as chalk or talc, or dissolved in water.
  • Calcium carbonate is a desired filler material because it has certain advantages. It is one of nature's own construction material, such as in egg shells. Egg shells contain about 90% calcium carbonate by weight. (Unless specified otherwise, all percentages stated herein are percentage by weight.) Once it is used, the calcium carbonate can be dissolved by water or digested by living creatures as part of their food, so that the calcium carbonate is recycled or reused by nature itself, like egg shells. Except that it decomposes much faster than common plastic material, the plastic composition material of the present invention has most of properties of common plastics. The material can be strong like other polyolefin materials. Containers for liquid made from plastic composition material may be relatively large, at least 2-liters in volume. The material can be very flexible.
  • a container made from the material can be rolled or folded into small configuration.
  • the material can have good heat-sealing properties and can be used in high speed heat-sealing packaging system.
  • the material is an excellent barrier for liquid and gas, so a container made from the material can provide a long shelf life for the contents in the container.
  • the material is safe and compatible with most foods or medicines and many other products.
  • the material has excellent printability. Unlike common plastics, the material has very good cold and heat resistance properties
  • the material is opaque.
  • the plastic composition material has shown excellent heat conductivity which makes it suitable for a container used for products that are to be consumed in a heated condition, such as pap for babies.
  • a filled container can thus conveniently be heated in the microwave oven or a hot water bath, and then be used as a baby bottle. It can have high stiffness if necessary.
  • the mineral based filler content should be above about 30%.
  • the mineral based filler content should not be too high, i.e. less than 90%, otherwise the filler/binder mixture may be brittle and relatively easily breakable upon impact, like egg shells.
  • the amount of mineral based filler material content in the resulting plastic composition material is preferably in the range of 30-70%.
  • the range of about 50-60% of mineral based filler material in the resulting mixture is more optimal.
  • the most desirable plastic composition material is to have about 55% mineral based material and about 45% polyolefin.
  • calcium carbonate is the mineral based filler material
  • calcium carbonate content is preferably in the range of about 50% to about 70%, with the remainder being primarily polyolefins or other suitable plastic material.
