Abstract
Description
- The present invention relates to cold packs and storage containers for perishables.
- Cold packs are indispensable in todays world. They have numerous commercial and non commercial uses, such as cooling food, medical materials, or chemicals. Traditionally cold packs have an exterior shell that is either hard or soft. The hard shell cold packs are useful in many applications but suffer from drawbacks including lack of flexibility, and thickness due to the shell material. Many soft shell cold packs suffer from drawbacks including inability to hold consistent thickness or shape. A cold pack that is flexible, thin, and consistent in thickness and shape would be very useful in many applications.
- At social events, or in kitchens, two containers or other shaped containers are often stacked together, the bottom container holds a small amount of ice, the top container is placed on the ice and contains perishables. The ice in the bottom container keeps the contents in the top container fresh for an extended period of time. The two container cooling system is problematic. One problem is that the ice melts into water. As the ice dissipates, the top container sinks into the bottom container, potentially displacing the water which may spill. Even if there is no spillage, it is often messy to clean up. Also, the ice is consistently cooling the base of the top container, but not the sides. This leads to inconsistent cooling. Another problem is that there must be ice available. A two container system would benefit from consistent, reliable and clean cooling system.
- Cold packs are often used medically, to cool certain areas of the body, such as the shoulder, elbow, heel, or head. The problem with medical cold packs is that they aren't shaped to fit efficiently on curved body parts. The medical cold packs are often bulky, have poor flexing capability, and are expensive. The medical industry would benefit from flexible and inexpensive cold packs.
- The present invention relates to cold packs for cold therapy, and cooling perishables.
- According to one aspect of the present invention, a cold pack includes a sack with a first sheet, a second sheet, each sheet having an outer perimeter, the sack having first edge, a second edge, a top edge and a bottom edge, the first sheet and second sheet are substantially the same size, and shape, the first and second sheet are sealed together along the outer perimeter of each sheet whereby a water tight sack is formed. The cold pack further includes a plurality of pockets integral to the sack, the first sheet and the second sheet are fused together at one or more points whereby resulting in pockets, each pocket having a fused perimeter portion and an unfused perimeter portion whereby a broken line boarder bounds each pocket. The cold pack further includes a substance with a high heat of fusion fills the sack including each pocket whereby each pocket holds a substantially equal amount of the substance according to the pockets relative size and the substance with a high heat of fusion is substantially uniformly distributed throughout the plurality of pockets.
- According to one aspect of the present invention, a storage container includes an outer container with an interior surface, an exterior surface, an open top and a base. The storage container further includes, an inner container with an interior surface, an exterior surface, an open top and a base, the inner container is substantially the same shape as the outer container and having a volume smaller than the outer container such that it fits in the outer container. The storage container further includes one or more spacers connecting the inner container with the outer container whereby forming a substantially uniform space between the interior surface of the outer container and exterior surface of the inner container. The storage container further includes a cold pack for fitting within the space between the inner surface and the outer surface such that the cold pack substantially fills the space, with a portion to accommodate the one or more spacers.

cold pack 1 is used in the specification to describe embodiments of the invention.FIGS. 1a-1e depict varying embodiments of acold pack 1, specifically each with adifferent pocket 3 pattern. As shown inFIG. 1a , eachpocket 3 is similar to a hexagon, or partial hexagon shape. Theboarder 36 of thepocket 3 includes a fusedportion 4 and anunfused portion 5. The fusedportion 4 andunfused portion 5 alternate, creating thepocket 3. Thepocket boarder 36 holds a substance with a high heat offusion 3 a (shown inFIG. 7 ), such as gel refrigerant or water, but also allows thesubstance 3 a to migrate between thepockets 3. The Substance with a high heat offusion 3 a will simply be referred to as “gel refrigerant,” though note that thegel refrigerant 3 a is exchangeable with other substances commonly used in cold packs. The ability for thegel refrigerant 3 a to migrate is important when thecold pack 1 is filled from an opening 35 (as shown inFIG. 1e ). Thegel refrigerant 3 a must be able to migrate from the point of entrance or filling point, theopening 35 into eachpocket 3. Once thecold pack 1 is filled withgel refrigerant 3 a theopening 35 is heat sealed closed. Thebroken boarder 36 of the pocket which includes the fusedportion 4 and theunfused portion 5 fulfils two purposes: to allow the gel refrigerant 35 to migrate from thefilling point 35 throughout thecold pack 1 and to support thegel refrigerant 3 a so that it maintains a substantially uniform distribution throughout thecold pack 1. This purpose can be achieved through any number of configurations. For example,FIG. 1b shows thepockets 3 in a form similar to a hexagon. It is different than the shape inFIG. 1a ; the hexagon like shape is of a different character, but it functions similarly in that it allows for thegel refrigerant 3 a to migrate but also supports thegel refrigerant 3 a and contains a portion of within thepocket 3.FIG. 1c shows off-set circle pockets 3 andFIG. 1e shows diamond shape pockets, both having the same functions. The shape of thepocket 3 also affects the flexibility. - As shown in
FIG. 3 , thecold pack 1 includes afirst sheet 11 and asecond sheet 12 heat sealed together at each sheetsouter perimeter 2. As shown inFIG. 1d , the result of heat sealing results in asac 14 shown withpockets 3. Thepocket boarder 36 is formed by heat sealing thefirst sheet 11 andsecond sheet 12 together at the fusedportion 4. For example, inFIG. 1e the ‘x’ pattern is heat fused and theboarder 2 is formed by heat fusing thefirst sheet 11 andsecond sheet 12 together. This is the same for all of thecold packs 1 illustrated. For further example inFIG. 1c , the half circle pattern is heat fused. Anopening 35 is unfused until thecold pack 1 is filled withgel refrigerant 3 a. Once thecold pack 1 is filled, thefirst sheet 11 andsecond sheet 12 are heat sealed together at the cold pack opening 35 to create a water-tight-sealedsack 14. - The
sheets cold pack 1 can have a fiber texture on the exterior of thesheets - The
cold pack 1 shown inFIG. 2 , includes thepockets 3, atop edge 6 and abottom edge 7, a first edge 8 and asecond edge 9. Thecold pack 1 is cut to form atop edge 6 with an arc shape of a substantially uniform radius. Thecold pack 1 is further cut to form thebottom edge 7 with an arc shape of a substantially uniform radius. The arc of thebottom edge 7 has a smaller radius than the arc of thetop edge 6. If the first edge 8 and thesecond edge 9 are heat sealed together the resultingcold pack 1 is shaped similar to a cone without an apex. Though acold pack 1 in the form of a cone with an apex is possible. Thecold pack 1 is configurable. - As shown in
FIG. 3 , thegel pack 1 is heat seamed together at the first edge 8 and the second edge 9 (both shown inFIG. 2 ) resulting inseam 10 and a curved shape that can be used for medical purposes. Multiplecold packs 1 varying in sizes and shapes may be heat fused together to create a shape needed for the application. Thepocket 3 allows thecold pack 1 to curve while maintaining a substantially consistent shape. The curvature is efficiently obtained because the fusedportions 4 of thepocket 3 is absent of gel and depressed. When the gel pack curves, thepocket 3, which bulges because of thegel refrigerant 3 a, assumes the space to the inside of the curve, and to the outside of the fusedportion 4. The smaller the size of thepocket 3 the greater the curvature thegel pack 1 can maintain. The larger the size of thepocket 3 the greater volume of gel refrigerant the pocket can hold, but the less curve it can maintain. - As shown in
FIG. 4a-e , thegel pack 1 can include astrap 13. Thestrap 13 is connected to thegel pack 1 and wraps around one or more body parts for hands free application of thecold pack 1 to the body. The depictions inFIG. 4a —e are illustrative. The shape and form of thecold pack 1 is configurable to have more or less curvature by changing the size and shape of thepocket 3, the number ofseams 10 or shape of thesack 14.FIG. 5 shows how multiplecold packs 1 are seamed together (seams 10 are shown) to form a square or rectangle shape. - As shown in
FIG. 7 , acold pack 1 as described inFIG. 6 is contained in an outer container (here depicted as a bowl) 17. When thecold pack 1 is placed in theouter container 17, theelongated chambers 15 compress into theelongated cutouts 16 to form a smaller radius but maintain a substantially consistedgel refrigerant 3 a layer. Thecold pack 1 rests substantially flush in theouter container 17. Thegel refrigerant 3 a is shown giving each pocket a three dimensional shape. Theouter container 17 includes aspacer 18 shaped like a cylinder and integral with the bowl. Thespacer 18 is hollow inside for receiving anotherspacer 18. - As shown in
FIG. 6 andFIG. 7 , acold pack 1 includes a plurality ofelongated chambers 15 integral to thegel pack 1 and located at the bottom edge of thecold pack 1, theelongated chambers 15 are created byelongated cutouts 16 starting at thebottom edge 7 of thecold pack 1 and extending toward thetop edge 6 of thegel pack 1. As shown inFIG. 7 , the portion of thecold pack 1 withelongated chambers 15 andelongated cutouts 16 decreases in diameter and flex under pressure. When thegel pack 1 is place in a bowl-like container 17, and oriented such that theelongated chambers 15 are located near thebase 19, as shown inFIG. 7 , the decreasing diameter of thebowl 17 puts pressure on theelongated chambers 15. The pressure causes theelongated chambers 15 to merge into theelongated cutout 16 space, essentially creating a solid area of gel pack with noelongated cutout space 16. This allows for substantially even cooling across all surfaces except where thespacer 18 is located. The perimeter of theelongated chambers 15 are heat sealed whereby the chambers are for holding thegel refrigerant 3 a. Thegel refrigerant 3 a moves freely from thepockets 3 in thecold pack 1 into the elongated chambers. Though, it is possible that theelongated chambers 15 are separate from the remainder of thecold pack 1, it would make filling thecold pack 1 with gel possibly more time consuming. - As shown in
FIG. 7 , thegel refrigerant 3 a fills thepocket 3 so that the surface of thegel pack 1 is slightly wavy. The peak of the wave is approximately at the center of thepocket 3 and the trough is at the fusedportion 4. The difference between the height of the peak and the trough depends on the size of thepocket 3. The larger thepocket 3, the greater the difference. Thus,smaller pockets 3 curve better andlarger pockets 3 have a greater cooling potential. Thecold pack 1 is configurable to balance cooling potential with flexibility by changing the size and shape of thepockets 3. -
FIG. 9 shows astorage container 39 including anouter container 17 andcold pack 1 that includes all of the elements and details as shown and described inFIG. 7 . Thecold pack 1 is shown without the details illustrated inFIG. 7 . However, thecold pack 1 shown inFIG. 7 is ideal for integrating with thestorage container 39 as shown inFIG. 9 . In addition,storage container 39 includes theinner container 24 which is stacked in theouter container 17 to create the space 38 (as shown inFIG. 8 ). Theinner container 24 includes aspacer portion FIGS. 8, 9, 11, and 12 , the female portion of thespacer 31 is integral to theinner container base 27 and the male portion of thespacer 18 is integral to theouter container base 19. Thefemale portion 31 is configured to fit securely in themale portion 18. As shown inFIGS. 11 and 12 , thespacers FIGS. 8 and 9 , thespacers spacers inner container 24 andouter container 17 so long as the resultingspace 38 housed thecold pack 1. As shown, thespacers female portion 31 could be solid, instead of a hollow ridge as shown. -
FIGS. 9 and 12 are essentially the same except for their shape and the configuration of the elements that the shape dictates. As shown inFIG. 12 , thestorage container 39 is a square or rectangle. The resultingcold pack 1 is therefore square or rectangle. Thecold pack 1 is configured essentially as shown inFIG. 5 . Thecold pack 1 is created by heat sealing fourcold packs 1 to the edges of acold pack 1 that forms a base, the fourcold packs 1 are seamed creating approximately right angles with the basecold pack 1, all extending in the same direction, and heat seamed at the corners to create an open box structure. The resulting seams 10 are shown inFIG. 5 . One of thecold packs 1 will contain an area that allows for thespacer 18 & 31 to support theinner container 24. Ideally the area will be a cutout the same shape substantially and the same size as thespacer 18 such that the perimeter of the cold pack cutout rests against thespacer 18 base to stabilize thecold pack 1 from shifting and optimizing the cooling potential. The could pack 1, ideally, should be substantially the same height and width as the walls of the container it is configured to. It however could be of a height that is shorter. - The
storage container 39 also includes achamber 26 for receiving perishables and aspace 38 for receiving one or more cold packs 1. Theperishable chamber 26 is the inner cavity of theinner container 24. Theinner container 24 has aninterior surface 32 and anexterior surface 37. Theinterior surface 32 is the surface that will support perishables. Thespace 38 for receiving thecold pack 1 is bounded by the innercontainer exterior surface 25 and the outer containerinterior surface 37. Thespace 38 is substantially uniform with a substantially consistent width. Thespace 38 has a consisted slope create by the slope the innercontainer exterior surface 25 and the outer containerinterior surface 37. If thespace 38 was irregular, multiplecold packs 1 with pockets of varying size could conceivably be fused together to meet this need. - Unless, a user would like to put the
whole storage container 39 in the freezer, theinner container 24 is removable. Theinner container 24 is removed so that the cold pack may be removed and chilled or frozen separate from thestorage container 39. This benefit saves freezer space. The cold pack is then placed back into thespace 36 and theinner container 24 is placed back inside the outer container such that thefemale spacer 31 fits substantially snug in theouter containers 33male spacer 18. Theinner container 24 andouter container 33 can be made of a variety of materials such as plastic, metal or wood. - The
lid 22 as shown inFIGS. 9 and 12 , include achamber 23 for holdingwater 3 a. Thechamber 23 also has a raised portion, anair chamber 30. Theair chamber 30 allows for water to expand as it changes state from liquid to solid. Thelid 22 includes anopening 28 and a reusableclosure cap lid 29. Thechamber 23 can be filled and emptied as needed. Theopening 28 and a reusableclosure cap lid 29 are position such that the when a user fills thechamber 23 with water or similar substance theair chamber 30 will not fill with water. Thechamber 23 may be configured as to size including depth. However, the heat transfer increases as the surface area of thechamber 23 exterior that is exposed to theperishable chamber 26 increases. To maximize heat transfer thechamber 23 should have an area only slightly less than the surface area of the inner container's opening and it should extend into the inner container's opening. -
FIGS. 8 and 11 show two variations of astorage container 39. The essential difference betweenFIGS. 8 and 11 is the shape of thestorage container 39, the difference in how thecold pack 1 is configured which is discuss above and the lid. Thelid 22 as shown inFIGS. 8 and 11 , is similar to the lidFIGS. 9 and 12 in but it is designed to receivegel refrigerant 3 a inchamber 23. The gel refrigerant can 3 a be permanently sealed in thelid 22. In this case, thelid 22 is removed and placed in a freezer to chill. In the alternative, a gel pack is placed in thechamber 23 and can be removed for freezing. - The
storage container 39 can be packed in a cooler (not shown) alleviating the need for adding ice or ice packs. Thestorage container 39 are stacked to save space in the cooler. - An embodiment of the
cold pack 1 for medical uses would havepockets 3 of varying size. An area with relativelylarge pockets 3 and an area with relativelysmall pockets 3 for flexing around a body curvature.
