Abstract
Description
- Field of the Invention
- This invention relates to the field of soft sided insulated containers. In particular it relates to soft sided insulated containers having removable impermeable liners for discouraging or preventing the leakage of liquids.
- In recent times soft sided insulated containers have become popular for carrying either articles that may best be served cool, such as beverages or salads, or warm, such as appetizers, hot dogs, and so on. Such containers are frequently used to carry liquids, whether hot liquids, such as soup containers, coffee or tea, or cold liquids such as beer pop, juices and milk. The containers are typically made in a generally cube like shape, whether of sides of equal length or not, having a base, four upstanding walls, and a top. The top is generally a lid which opens to permit articles to be placed in, or retrieved from, the container.
- By the nature of their use, it is advantageous for the containers to be water tight. That is, whether to hold melted run-off from ice cubes or to hold spilled liquids, the container must be sufficiently liquid tight that it does not leave a trail of drips, or become moist or sticky to the touch of a person carrying the container.
- The present inventor has found it disadvantageous to try to seal the container itself. The type of insulating wall used by the present inventor is generally sewn at its seams. Sewn seams have a tendency to leak at the stitches. Another approach is to fold the insulated blanket from which the container is made, to present an assembly that, through folding, has no seams. This is also disadvantageous, in the present inventor's view, because the insulated blanket used to form the container walls is relatively thick. The thick material does not fold well, in the inventor's view. It would be preferable to form an impermeable layer that has a relatively thin wall thickness so that the resulting product does not look bulky and cumbersome.
- It is also advantageous to be able to clean the inside of the insulated container. Spilt liquids may not always have the most attractive air when allowed to dry, and may cause the inside of the container to become unsightly. It is possible to provide a plastic liner for soft sided insulated containers. A see through plastic liner can be made of the minimum amount of material by using only a single layer, and forming seams where the edges of the material meet. A common method of forming such a seam is to weld two adjacent edges together by heating. However, an existing liner of this type is known to have had a tendency for the heat welded seams to develop leaks over time. It would be advantageous to reduce or eliminate the number of heat welded seams formed in areas of the liner that may need to be water tight.
- In general, manufacture of an assembly of this type emphasizes cost reduction. One common source of cost savings is a reduction of the raw material used. However, the present inventor has observed, counter-intuitively, that the overall benefit an increase in raw material use can outweigh the cost saving that would otherwise be achieved. Unexpectedly, the use of a greater amount of material in a folded assembly has been found to be advantageous, and has eliminated the need to have a heat welding station in manufacture.
- In an aspect of the invention there is a soft-sided insulated container, and a removable liner for placement inside the container. The liner is folded from a monolithic sheet of liner stock to define a chamber, capable of holding liquids. The liner is free of heat welded seams.
- In another feature of that aspect of the invention the liner is made from a water impermeable plastic sheet. In an additional feature of that aspect of the invention the liner is made from a translucent static cling vinyl sheet. In another additional feature of that aspect of the invention the soft sided insulated container has a base, sides and a top. The liner has a base, sides for placement inside and adjacent to the base and sides of the container. The top of the container is moveable to an open position to permit articles to be placed in the chamber.
- In still another additional feature of that aspect of the invention the chamber has an opening, the opening having a lip, and the liner is mated to the cooler about the lip. In yet another additional feature of that aspect of the invention the opening has four sides, the lip extends about the four sides opening and the liner is mated to the container on the four sides. In a further additional feature of that aspect of the invention the liner has a rectangular base and four sides extending from the base, each of the sides having an edge adjoining the base and a distal edge distant from the base. The chamber has an opening defined between the distal edges of the sides.
- In a still further additional feature of that aspect of the invention one of the sides has a lid member extending therefrom, the lid member being moveable to close the opening of the liner. In yet another additional feature of that aspect of the invention the lid member is a flap formed integrally with the liner, the flap having four lid edges, one edge being a folded hinge edge adjoining one of the distal edges of the sides, the remaining three lid edges having a closure for mating with the remaining three distal edges.
- In another aspect of the invention there is a removable liner for placement inside the container. The liner is formed from a water impermeable plastic sheet. The sheet has a periphery. The liner has a quadrilateral base and four sides extending from the base to define a chamber therebetween capable of holding water. Each of the sides are joined to the base at a base edge. Each of the sides has a pair of lateral edges each meeting the base edge at a corner. Each of the sides has an edge opposed to the base edge and meets each of the lateral edges at a corner. The sheet has corner portions defined between adjacent lateral edges of two of the sides and the periphery and the corner positions are folded to lie against the sides.
- In a further additional feature of that aspect of the invention the base is a rectangle and two of the sides, joined to the base on opposite sides of the rectangle, are trapezoidal. In a still further additional feature of that aspect of the invention the chamber has the shape of an inverted, truncated rectangular based pyramid. In yet another additional feature of that aspect of the invention the container has an internal face made from a reflective material and the liner is transparent.
- In another aspect of the invention there is a soft sided insulated container, and a removable liner for placement inside the container. The liner is formed from a water impermeable plastic sheet. The sheet has a periphery. The liner has a rectangular base and four sides extending from the base to form a chamber therebetween, each of the sides being joined to the base at a base edge. The sheet is folded on a first pair of parallel fold lines to define one pair of the base edges. The sheet is folded on a second pair of fold lines to define the remainder of the edges. The sheet has four corner portions each defined between an end portion of one of the first pair of fold lines, an adjacent end portion of one of the second pair of fold lines and the periphery, and the corner portions are folded to lie against the sides.
- In an additional feature of that aspect of the invention the sides have an inside face and an outside face and the corner portions are folded to lie against the outside faces. In another additional feature of that aspect of the invention each of the corners is folded to form a triangular flap, and each of the flaps is folded to lie against one of the sides. In still another additional feature of that aspect of the invention one of the triangular flaps is folded to lie against each of the sides of the liner. In still yet another additional feature of that aspect of the invention two of the triangular flaps are folded to lie against one side of the liner. In a further additional feature of that aspect of the invention two of the triangular flaps are folded to lie against one side of the liner, and the other two triangular flaps are folded to lie against another side of the liner.
- In still a further additional feature of that aspect of the invention each of the sides has a distal edge opposed to its respective base edge. The chamber has a lip defined by the distal edges. The corner portions are fastened to the sides adjacent the lip. In still yet a further additional feature of that aspect of the invention one of the sides has a cover flap formed integrally therewith, and joined thereto at a cover fold, the cover flap mating with the distal edges of the remaining sides of the liner. In an additional feature of that aspect of the invention the container has a reflective inner surface and the liner is transparent.

- The description which follows, and the embodiments described therein, are provided by way of illustration of an example of a particular embodiment, or examples of particular embodiments, of the principles of the present invention. These examples are provided for the purposes of explanation, and not of limitation, of those principles and of the invention. In the description which follows, like parts are marked throughout the specification and the drawings with the same respective reference numerals. The drawings are not necessarily to scale and in some instances proportions may have been exaggerated in order more clearly to depict certain features of the invention.
- Referring to the general arrangement illustration of FIGS. 1 and 2, an example of a preferred embodiment of an insulated container and liner assembly according to the principles of the present invention is indicated generally as20. It has two major elements, those being an outer casing in the nature of a soft-sided
insulated container 22, and a removable,impermeable liner 24 for placement insidecontainer 22. An optional moveable bulkhead, or baffle, in the nature of apartition wall 25 seats withinline 24 for dividing the interior space into two sub-compartments 27 and 29. - Looking at these major elements in detail, it can be seen that
container 22 has a bottom 26, afront panel 28, arear panel 30, and a pair of left and righthand side panels front panel 28,rear panel 30, and left and righthand side panels bottom vertices front panel 28 andside panels top edges Rear panel 30 is joined by a foldedhinge 44 at its top edge to a top panel in the nature of alid 46.Lid 46 has a closure member in the nature of azipper 48 extending in a U-shape around the three free edge portions of its periphery to mate with the other portions ofzipper 48 positioned about the threetop edges panels Lid 46 is moveable between a closed position, in whichzipper 48 may be zipped closed, and an open position in whichlid 46 is folded back to permit entry and exit of objects to and from aninternal cavity 50 defined between bottom 26 andpanels auxiliary pouch 52 is mounted to the front face offront panel 28. - In the preferred embodiment,
lid 46 has an extent substantially equal to that ofbottom panel 26. This need not be the case.Lid 26 could be a small opening set in a larger top panel, or could be an opening of half, or some other portion of the panel. The opening need not extend fully along three sides oflid 26, but could extend along part of one or two sides as may be found suitable in a particular use. -
Top edges cavity 50. On the inside of rim 54 is a liner securing means, or liner attachment mounting, in the nature of azipper 56, which, in the embodiment illustrated, includesportions panels panel 30. Although this arrangement is preferred, in an alternative embodiment all ofstrip portions -
Container 22, withliner 24 installed, can be folded to a collapsed position, as shown in FIGS. 7, 8 and 9. In this collapsed, or storage position,side panels front panel 28 to move towardrear panel 30.Lid 46 is then drawn forward and downward in front offront panel 28 andauxiliary pouch 52.Lid 46 has, on its inner face, spaced inwardly fromzipper 48, a retainer in the nature of another hook andeye fastener strip 62 that engages a mating hook andeye fastener strip 64 located on a lower portion of the front face ofauxiliary pouch 52. In addition, left and righthand side retainers auxiliary pouch 52 offront panel 28 are drawn around to fasten to fastening strips 70 and 72 located on the outer, rearward face ofrear panel 30. (Whencontainer 22 is in its open position, strips 66 and 68 engagestorage strips 74 and 76 located onside panels - Other features of
container 22 are visible in FIGS. 1 and 2. Front and rear carrying handles 78 and 80 with reinforced bails are attached to bothfront panel 28 andrear panel 30 to permit two people to carryassembly 20 between them. In thepreferred embodiment assembly 20 has a maximum capacity of 24 quarts. Smaller embodiments, include a twelve quart container. Asingle shoulder strap 79 is attached toside panels elasticized retaining matrix 82 permits other materials, such as cups, plates, serving utensils or other objects to be carried on top ofassembly 20. Abovestrip 64,auxiliary pouch 52 has a see-throughmesh pocket 84, such as may be convenient for carrying knives, forks, spoons or other objects. - FIG. 10 shows a cross section of
front panel 28 withliner 24 in place. A scab section ofpanel 34 is also shown to reveal its layers of construction. With the exception ofauxiliary pouch 52, this section is typical not only offront panel 28 but also, generally, ofrear panel 30,side panels bottom panel 26 andlid 46. The outer facing layer offront panel 28 is acanvas covering layer 88 for resisting abrasion. It overlays a closed cellfoam insulation layer 90. The inner face ofinsulation layer 90 is covered by flexible plasticisedmetallic foil sheeting 92 that is shiny and reflective. The material is sold under the name Therma-Flect (T.M.).Liner 24 lies insidesheeting 92, and is pressed against it by the objects it contains. The inside ofpouch 52 is lined with white vinyl sheeting, 93 on its forward and bottom sides. -
Liner 24, is shown in FIGS. 2 and 3. It is made from a membrane, or web, in the nature of asheet 100 of flexible, transparent plastic stock, in particular, static cling vinyl. The shiny, reflective surface ofsheeting 92 is visible throughliner 24 in use.Liner 24 has abase 102 and four sides, front, rear, left hand and right hand respectively, 104, 106, 108, and 110 extending upwardly frombase 102. Each ofsides base 102 at a base edge, 112, 114, 116 or 118, as indicated, and each has an opposite,distal edge upstanding corners chamber 136 is defined betweenbase 102 andsides Chamber 136 has anopening 138 defined by theperipheral lip 140 formed collectively by thedistal edges sides lip 140 liner support fasteners, in the nature of hook and eye strips, are mounted tosheet 100. This mounting may be by heat welding or by use of a bonding agent or adhesive. In thepreferred embodiment lip 140 is folded over to form a hem, andfasteners lip 140, and afastener 142 in the nature of a fabric hook-and-eye strip are sewn in place with stitching 145 that is at a height relative to base 102 that is expected to be well above the liquid level inliner 24. - In an alternate embodiment,
fasteners lip 140, and which mate with corresponding hook-and-eye fastener strips mounted tocontainer 22. These fastener strips are commonly sold under the name Velcro (T.M.).Optional partition 25 is variably positionable. About the upper portion of its periphery it has astrip engaging material 146 that catches onmating strips liner 24. These strips can be hook and eye fastener strips. The range of the strips permits the division of sub compartments 27 and 29 ofchamber 136 into equal, half-and half portions, or into some other portions, such as ¼ to ¾, ⅓ to ⅔, ⅖ to ⅗ and so forth as may be found desirable given the objects to be contained inchamber 136. - In FIG. 3
sheet 100 is shown in developed view, as it would be before being folded to formliner 24. A first pair ofparallel fold lines sheet 100, and a second pair ofparallel fold lines lines sheet 100, thus dividing it into nine portions within the rectangular periphery, 158, ofsheet 100. It will also be noted that each oflines periphery 158. - The central portion of
sheet 100, bounded by the central sector of each oflines base 102, each of those sectors defining one of base edges 112, 114, 116 and 118.Front side 104 is defined between thecentral sector 160 ofline 150, two parallelforward end sectors lines mid-edge sector 166 ofperiphery 158.Rear side 106 is defined by thecentral sector 168 ofline 152, two parallelrearward end sectors lines mid edge sector 174 ofperiphery 158.Left hand side 108 is defined bycentral sector 176 ofline 154, twoleft end sectors lines mid-edge sector 182 ofperiphery 158.Right hand side 110 is defined bycentral sector 184 ofline 156, tworight end sectors lines mid-edge sector 190 ofperiphery 158. - The remaining four portions of
sheet 100 arecorner portions periphery 158, indicated respectively as 202, 204, 206 and 208.Corner portions diagonal bisectors periphery 158. - Having thus defined the geometry of
sheet 100,liner 24 is formed by foldingsides sectors corners corner portions - When folded along
bisectors corner portions triangular flaps front side 104, the corner offlap 220 lying most distant fromcorner 128 overlapping the corner offlap 204 lying most distant fromcorner 130. Similarly flaps 224 and 226 are folded to lie against the outside face ofrear side 106 the most distant corner offlap 224 overlapping the most distant corner of flap 226. One edge of each flap lies roughly flush withlip 140, which is folded over and the entire periphery of opening ofchamber 136 sewn as ahem 228 having a double row of stitches. In thisway liner 24 is formed fromsheet 100 such that it is not only free of welded seams, but free of any seams belowhem 228 oflip 140. - In the preferred embodiment the folding process is purely mechanical, and can be performed relatively quickly, in contradistinction to heat welding or adhesive bonding processes which require a time interval for heating and cooling or for adhesive curing. Inasmuch as the preferred embodiment uses a relatively thick static cling vinyl,
sheet 100 can be folded over a cube form of the desired dimensions, and held in place by its own clinging properties in preparation for the sewing ofhem 228. The overlap of the tips offlaps liner 24 will unfold. -
Liner 24 is formed from a single integral sheet, and, absent punctures of that sheet is not intended to leak below the level of the sewn seam atlip 140. The body ofbase 102 andsides chamber 136 is not expected to be greater than one half of the height of the sides, and still less commonly to be more than three quarters of the height. There are no seams below either of these levels, heat welded or otherwise. -
Liner 24 is also thin enough that it can be folded insidecontainer 22 whencontainer 22 is compressed to its collapsed position as illustrated in FIGS. 7, 8, and 9.Liner 24 need not be transparent, but could be translucent or opaque. A transparent liner is preferred since it permits the reflection ofsheeting 92 to be seen. - In an optional embodiment, a
liner 224 can have its own closure, or lid, 230, to provide a double closure withlid 46 ofcontainer 22 in FIG. 11. As shown in FIG. 11,optional lid 230 extends on afolding plastic hinge 232 that is an integral part ofsheet 234 fromrear side 236 ofsheet 234, and mates at front, left hand and right hand side edges 238, 240 and 242 along a U-shaped closure interface such as may be held closed by a closure member in the nature of a seal, a zipper, a hook and eye fabric fastener, or a similar device. It is not necessary that the opening of the container, or the liner, form a parallel plane to the respective base or bottom sides. The opening could be in a skewed plane, or could be something other than a plane. - In alternative embodiments, one of each of corner flaps220, 222, 224 and 226 can be folded against each of
sides left hand side 108 and another pair (222, 226) againstright hand side 110, rather than against front andrear sides lip 146. However, if the corner portions are cut down, the height at which a liquid tight barrier is provided may not necessarily be as high as shown in the preferred embodiment of FIG. 1. It is also not necessary thatcorner portions - As shown in the developed views of the alternate embodiments of FIGS. 4, 5, and6, the liner need not be a cube or cuboid, but could be a tapered, trapezoidal, or truncated pyramidal shape. In the embodiment of FIG. 4 a
developed sheet 300 has fold lines for forming a liner having a pair of opposedtrapezoidal sides base 308, and a pair of opposed rectangular sides that are folded upward at an angle corresponding to the rake angle a oftrapezoidal sides parallel fold lines central sector right end sectors fold line sectors sectors 314 and 316). The intersections ofsectors base 308. Extending away from those corners toperiphery 330 are left and right hand cantedtrapezoidal side sectors trapezoidal sides sectors portion fold lines Corner portions periphery 330, have been trimmed alongperiphery 330 to lie flush with the resulting lip. Whensheet 300 is folded in a manner analogous to the folding ofsheet 100, a cradle shaped liner will result, for mating use with a similarly cradle shaped container analogous tocontainer 22. - In the embodiment of FIG. 5 a
developed sheet 400 has fold lines for forming aliner 402 having a first pair of opposedtrapezoidal sides base 408, and a second pair of opposedtrapezoidal sides trapezoidal sides fold line sector hand end sectors fold line sectors 418 and 420 which define the remaining two sides ofbase 408. The intersections ofsectors base 408. Extending away from those corners toperiphery 430 are left and right hand trapezoidal sidelateral sectors trapezoidal side sectors periphery 430 to define the remaining vertices of the trapezoidal sides. At the angular bisector of the included angle between adjacent pairs of rectangular side lateral sectors and trapezoidal side sectors, as, for example betweensectors portion fold lines -
Sectors sectors sections - When folded in a manner analogous to the folding of
sheet 100,sheet 400 will form a truncated, inverted rectangular shaped pyramid. It should be noted that the pairs of opposed slanted pyramid sides need not rise at the same angle, but could be at different angles. In the most general case, each side could rise at a different angle, and to a different height. The upper edges of the sides need not be level, but could have a slant, or, alternatively, need not be linear but could be curved as may suit the desired geometry. However, it is expected that the sides will, most often, have straight and level edges. - In the embodiment of FIG. 6, a
developed sheet 500 has fold lines for forming aliner 502 having atrapezoidal base 504 such as might be desired in a knapsack having a large rearward face for placement against a person's back, and a narrower outer or forward face. A pair of parallel lines of unequal length, being a shortfront fold line 506 and a longerrear fold line 508, define the parallel sides of thetrapezoidal base 504. A pair of left and right handside fold lines lines trapezoidal base 504.Front side 514,rear side 516,left side 518 andright side 520 are all hinged alongrespective fold lines base 504.Corner portions periphery 530 and respective pairs ofside sectors portions fold line - A preferred embodiment has been described in detail and a number of alternatives have been considered. As changes in or additions to the above described embodiments may be made without departing from the nature, spirit or scope of the invention, the invention is not to be limited by or to those details, but only by the appended claims.
