Description

BACKGROUND

Commonly, potable water is distributed to the consumer in plastic or glass bottles of various sizes and shapes, whereas ice is distributed in blocks or in individual plastic bags.

Distribution of water in bottles has a number of disadvantages. Firstly, when the bottles are empty they tend to retain their shape, thus creating a large volume of waste material. Secondly, bottles tend to crack or split if the water in them is frozen, since water expands as it cools. Bottles are therefore not suited to the distribution of ice.

In some situations, such as when emergency relief is needed at a particular location, there is often a need for both ice and water. Ice may be needed for a variety of purposes, included the preservation of perishable foods and for personal cooling, while water is required for hydration. In such situations, those seeking relief must carry unwieldy containers of water (either large containers or multiple bottles) as well as bags or blocks of ice.

There is also a need to transport and store other materials, such as other liquids and solids, in both frozen and non-frozen states in a manner that is efficient, doesn't take much room and is versatile.

DETAILED DESCRIPTION

Before describing in detail embodiments that are in accordance with the present invention, it should be observed that the embodiments reside primarily in combinations of method steps and apparatus components related to material (frozen or liquid) storage and transport. Accordingly, the apparatus components and method steps have been represented, where appropriate, by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present invention so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.

In this document, relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises . . . a” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.

FIG. 1 is a first view of an exemplary apparatus for material storage and transport in accordance with some embodiments of the invention. As used herein, the term material encompasses a variety of substances, and includes, but is not limited, to liquid, non-liquid or solid material, frozen or non-frozen, re-usable material, potable liquids and food suitable for human and animal consumption. Material as used herein thus may include liquid water or frozen water; liquid or frozen drinks for human or animal consumption like vitamin and sports water; medicine for human or animal consumption such as anti-biotics; food stuffs such as meals, condiments like mayonnaise, mustard, etc., which may or may not be frozen; household items like shampoo, soap, toothpaste, etc.

Referring again to FIG. 1, the apparatus include a container 100 constructed from one of more flexible plastic sheets. The container comprises a number of connected bags. Each bag has a chamber 102 for holding material. Each chamber is separated from an adjacent chamber by a web of the flexible plastic sheet. The webs have perforations 104 that allow adjacent bags to be separated from one another. It is noted that the one or more flexible plastic sheets of container 100 are flexible to permit holding water or ice or other material within the chambers 102 without leakage. This represents an advantage over the rigid water bottles of the prior art, for example, which crack as water freezes and expands.

In the embodiment shown in FIG. 1, the chambers are arranged in a strip. A loop of flexible material 106 is attached to the container 100 to form a carrying handle. As show, the loop of flexible material has an extended portion 108 that passes down a first side of the container and up a second side of the container, such that, when the apparatus is carried, the weight of material in the chambers is supported, at least in part, by the loop of flexible material. In an alternative embodiment, the loop of flexible material is only connected to the bag at one end of the container.

The loop of flexible material may be removably attached to the container. For example, the loop could be attached to the container using a low strength adhesive that allows the loop to be ‘peeled’ from the container when it is no longer needed.

The container and the loop may be constructed of thermoplastic. In one embodiment, the container is constructed of puncture resistant, polyethylene film and does not contain bisphenol-A; it is noted that in the case where the materials transported and/or stored in such containers are those for food consumption or medical use, the materials and their compositions may require food and/or drug regulatory approval. Non-biodegradable materials provide the advantage of being easy to collect and recycle for future use. Biodegradable materials may also be used and are especially attractive for short-term use in keeping with current “green” efforts. The chambers may be formed by heat sealing the periphery of the bag. Various types of heat sealing are known to those of ordinary skill in the art, these include continuous heat-sealers (also known as Band type heat sealers), impulse heat sealers that use a stationary element which is heated with each sealing cycle, hot bar sealers, and ultrasonic welders. Other methods of manufacture will be apparent to those of ordinary skill in the art.

The loop may be welded to the container and may be perforated at intervals to allow adjacent bags to be separated from one another.

The plastic sheet 110 forming a corner of each of the bags may be removable so as to allow material, such as liquid water or the like to be removed from the chamber. The corner may be partially notched or slit to facilitate tearing off the corner.

The number of chambers may be varied. The chambers may be arranged in a strip, as shown, or in a two-dimensional array.

FIG. 2 is an exemplary side view of the apparatus shown in FIG. 1. This view shows the chambers 102 for holding material. The chambers 102 are separated by a web of material 202 that is perforated so as to allow the chambers to be separated from one another. In this embodiment, the flexible loop 106 includes a lower portion 108 that passes under the lower chamber and extends up both sides of the container to form a carrying handle as shown in the drawing. In this embodiment the flexible loop 106 is attached to all of its length apart from the carrying loops.

FIG. 3 shows a further embodiment in which the extension 108 of the flexible loop is attached to the container at intervals, such as discrete locations 302.

FIG. 4 shows an embodiment in which a drinking straw 402 is embedded in a wall of each of the chambers 102. The straw 402 may have a valve or a snap-off end, so that material, like water may be removed from the chamber through the straw when required. The region 404 of the chamber wall where the straw is embedded may be reinforced.

FIG. 5 shows a further embodiment in which a nozzle 404 is embedded in wall of each of the chambers 102. The nozzle may be equipped with a cap or a valve, for example, to prevent unintended leakage, and may be re-sealable. The region 404 of the chamber wall where the nozzle is embedded may be reinforced. The valve may be a one-way valve that allows liquid material, like water, medicines, etc., to escape when the valve is pinched. The valve may be constructed of rubber or a rubber-like material.

The apparatus may be used for distributing material in liquid form or in frozen form, such as ice. For example, when emergency relief is needed at a particular location there may be a need for both frozen (such as ice) and liquid (such as water) states of a material. Frozen material, like ice, may be needed for a variety of reasons, included the preservation of perishable foods and for personal cooling. The apparatus of the present invention is well suited to this application.

FIG. 6 is a flow chart of a method for material distribution in accordance with some embodiments of the invention. Following start block 602 in FIG. 6, the chambers of the container are filled with liquid material, such as potable water, at block 604 and the chambers are sealed at block 606. At block 608, the material in the container is frozen. For example, this may be done before the container is transported to the region where emergency aid is required and distributed or while being transported in refrigerated vehicles, or at some other location. At block 610 the containers are distributed. They may be distributed complete, with multiple chambers and equipped with a carrying handle. Alternatively, one or more chambers may be separated prior to distribution. At block 612, the chambers are separated as needed by the user. Separation is facilitated by the perforations in the web separating the chambers. The frozen material may be used for cooling at block 614, such as for providing a cold compress if medically indicated. Once the frozen form of the material has melted, the liquid form of the material, i.e. water, may be used for drinking at block 616. In this way, both cooling and hydration needs are met. The method terminates at bock 618.

FIG. 7 shows a container 100 for storage and transport in accordance with some further embodiments of the invention. Referring to FIG. 7, the apparatus 100 comprises one or more flexible plastic bags 702 that form storage chambers 102. The bags 702 are coupled by one or more strips 108 constructed of a flexible material. The strip may have perforations 104 formed in the sections of strip between adjacent bags.

The plastic sheet 110 forming a corner of each of the bags 702 may be removable so as to allow material to be removed from the chamber 102. The corner of the bag may be partially notched or slit to facilitate tearing off the corner.

A loop of flexible material 106 is attached to the container 100 at a first end to form a carrying handle. The loop 106 may be formed of the same material as the strip 108 and may be integral with it. A corresponding hook 704 may be attached to the other end of the container. The hook may take a variety of forms and is designed catch in the loop 106, so that the container forms a loop of connected bags. The loop of connected bags may be carried over a person's shoulder for facilitated transportation. In FIG. 7, the hook comprises a substantially rigid bar that may be pass through the loop 106, or used as an alternative carrying handle.

The bags 702 may be constructed of a biodegradable material.

FIG. 8 is an exemplary side view of the apparatus shown in FIG. 7. This view shows the bags 702 for holding liquid or non-liquid material. The bags 702 are arranged side-by-side, or end-to-end, in a line and coupled by one or more strips of flexible material 108. The flexible material may be perforated so as to allow the bags to be separated from one another. Other ways of separating the bags will be apparent to those of ordinary skill in the art. These include strips that are notched for easy tearing, or strips that may be separated by peeling from one another or from the bag.

In the embodiment shown in FIG. 7 and FIG. 8, the flexible material includes a looped portion 106 that forms a carrying handle.

FIG. 9 shows a loop of connected bags. A loop of flexible material 106 is attached to the container 100 at a first end to form a carrying handle. A corresponding hook 704 may be attached to the other end of the container. The hook 704 may take a variety of forms and is designed catch in the loop 106, so that the container forms a loop of connected bags, as shown in FIG. 9. The loop of connected bags may be carried over a person's shoulder for facilitated transportation.

The bags may be spaced apart so as to facilitate stacking of bags. This is illustrated in FIG. 10. In FIG. 10, an upper group of four connected bags 102′ is supported on top of a lower group of connected bags, 102. The upper bags are located in the gaps between the lower bags. In this manner, a stable stack of bags may be built. Multiple groups of connected bags may be stacked for storage or distribution.

FIG. 11 shows an individual material storage and transport container 100 in accordance with some embodiments of the invention. The container comprises a plastic bag with a reinforced top portion 1102 and a reinforced lower portion 1104. Material, such as water or ice, may be contained in the interior volume 102. In one embodiment, the interior volume is sized to contain approximately 20 fluid ounces of water or other liquid material, but other sizes may be used. The reinforced portions may contain holes 1106 and 1108. These holes enable the bag to be supported by or joined by a hook, for example. A corner of bag may include a tear-off region 1110 that may be removed to allow material to be removed from the bag. Alternatively, a retractable straw 402 may be passed through a reinforced insert region 404 to allow liquid material like water to be removed from the bag.

FIG. 12 shows a strip of connected material storage and transport containers in accordance with some embodiments of the invention. The bags 100 are coupled by adjacent reinforced regions. The reinforced region may be perforated to allow the bags to be easily separated from one another. Having the bags joined together facilitates movement and storage of the bags. The reinforced region may be formed by heat seal, embedded portions containing string material (twine, burlap) that could be glued or sewn or embedded or heat-sealed to provide structural strength and reinforcement for larger bags of material, such as a liter of water that can weigh approximately two pounds each bag, or more. The embedded portions of string material may be of sufficient strength to allow multiple bags to be connected together. For example, 12 1-liter bags of water formed together may be quite heavy, requiring additional structural support. The strip of connected storage and transport containers may be formed or manufactured as a unitary, circular strip, having no discernable beginning or ending. This would have the advantage of allowing a person to transport multiple bags circularly formed over the shoulder, about the waist, etc. For example, it is noted that a person could carry two or more loops or strips of thus connected containers, one over each shoulder hanging straight down from the should or in a cross-body position. A portion of each of the loops thus carried could then be temporarily joined together between the carrier's shoulder blades or in the front of the person to make transport of multiple strips easier. Hooks, clips or the like could be used to removably and temporarily attach the multiple strips of containers together.

FIG. 13 shows a strip of connected material storage and transport containers, joined in a loop in accordance with some embodiments of the invention. In this embodiment, the reinforced regions of the first and last bag are joined by a hook 1302, which is shown in more detail in FIG. 14. Having the bags joined in a loop facilitates allows a person transporting to carry multiple bags looped over their shoulder. It also allows the loop of bags to be placed over an object such as a door, wall, or post.

FIG. 14 shows an exemplary hook for connecting material containers in a loop. In this example an ‘S’ shaped hook is used, although other shaped hooks may be used. Indeed, other methods of the joining the ends of the strip of bags may be used without departing from the current invention. Moreover, in the event of individual material containers, a top side of a container may employ a grommet, ring hole or the like for fastening it individually from an individual hook of a stand, such as that a number of containers so attached to the stand may resemble fish hanging from a fish hook stand.

FIG. 15 shows a single, elongated water storage and transport container 100 in accordance with some embodiments of the invention. In one embodiment, the interior volume of the container 100 is sized to contain approximately 1 liter of fluid material, like water. The ends of the container include reinforced regions 1102 and 1104. These ends may be joined by a hook or other connector 1302 that passes through holes in the reinforced regions. As described above, this allows the container to be formed into a loop for easy transportation by a person. When the hook is removed, the bag may be laid flat for storage.

In one embodiment, liquid material may be removed from the container 100 through a pinch spout 502 that passes through a reinforced region 404 of the wall of the container 100.

FIGS. 16 and 17 show an exemplary pinch spout for use with material storage and transport containers. Referring to FIG. 16, the end of the pinch spout 502 includes one or more slits 1602 that are held closed by the elasticity of the material from which the spout is manufactured. This prevents liquid material, like water, from escaping. To remove liquid material from the pinch spout, the user pinches the spout by applying pressure to the sides of the spout. This causes the sides of the slits to separate, as shown in FIG. 17, allowing liquid material to escape. The pinch spout may be covered with a substantially rigid cap to prevent accidental pinching of the spout and to keep the spout clean. Moreover, the container having a pinch spout may be augmented by a second tap for re-filling the container with material.

Other methods of removing material from the container 100 will be apparent to those of ordinary skill in the art.

FIG. 18 shows one end of an elongated container 100 with an opening for dispensation of material from the container in accordance with some embodiments of the invention. The container, which has one or more flexible plastic sheets joined to form a bag, may be used for material storage, transport and dispensation of materials such as liquids, gels, creams, pastes, gases and beaded or granular materials. Liquids may include, for example, beverages such as water, nutrient water, shakes, and non-beverage liquids. In the embodiment shown, the end of the container 100 has a reinforced region 1104 with hole 1108 configured to form a carrying handle. The other end of the container may be similarly configured, or configured to be inserted into hole 1108 such that the twos end of the container are joined to form a loop. When looped, the container may be conveniently carried over a shoulder, for example.

A hole 1802 formed in a flexible sheet that form a wall of the container is surrounded by reinforced region 404 for added strength. The reinforced region 404 may couple to a circular lip 1804 that is threaded to enable coupling to an attachment for material dispensation of a screw cap for closure. The hole 1802 may also be used to allow the container to be filled with material. A liquid material, once inside the container, may be frozen for transportation or storage.

FIG. 19 shows an attachment 1900 for dispensation of liquid material from the container in accordance with some embodiments of the invention. The attachment 1900 includes threaded shut-off coupling 1902 sized to couple with a threaded circular lip on a container.
