8 Claims. (Cl. 215-13) This invention relates to improvements in AnInsulated Picnic Jug or Container, particularly to such a jug or container wherein use is made of spaced apart inner and outer members and which members are interconnected with one another in operative spaced relation.

Insulated picnic jugs or containers of the spaced apart variety are relatively well-known'but in certain forms of this type of construction difficulty has been experienced in properly assembling the members and in retaining said members in operative locked relation to one another. By the present invention there is provided an improved construction wherein the faults and difiiculties of previous constructions are overcome.

This invention discloses improvements in and advancements over the disclosure in applicants pending application Serial No. 253,191 filed January 23, 1963.'

The principal object of the present invention is therefore the provision of an insulated picnic jug or container in which the parts thereof may be produced in such a manner that they are readily assembled with respect to one another to provide a unit not readily resolved to its individual parts.

Another object of the present invention is the provision of an insulated jug or container wherein the outer member is formed of several parts to be connected with one another and wherein the parts are keyed to insure proper assembly and subsequently prohibit relative movement therebetween.

A further object of the present invention is the provision of an insulated jug or container in which an inner liner or inner member is provided for use with a multipart outer member and in which means are provided for locking the said inner liner against relative rotation with respect to the outer liner.

A still further and specific object of the present invention is the provision of an improved method of forming, processing and assembling inner and outer members of an insulated container whereby the said inner and outer members may be readily connected with one another, keyed to one another to prevent relative movement after connection and in which a more complete water tight connection is effected between the parts.

Other objects and advantages of the present invention should be readily apparent by reference to the following specification considered in conjunction with the accompanying drawings forming a part thereof and it is to be understood that any modifications maybe made in the exact structural details there shown and described, within the scope of the appended claims, without departing from orexceeding the spirit of the invention.

FIG. 15 is a transverse sectional view through the body of the modified insulated jug as seen from line 15-15 on a portion of the modified insulated jug as seen from line 17-17 on FIG. 16.

Throughout the several views of the drawings similar reference characters are employed to denote the same or similar parts.

In general, and with particular reference to FIG. 3, the insulated picnic jug or container of the present inven- -tioncompiises an outer member, preferably formed of synthetic resin, plastic, and indicated in its entirety by the reference numeral 15, an inner member or container, again preferably formed of synthetic resin, plastic, and indicated in its entirety by the reference numeral 16 and with said inner container closed by a cap 17.

The outer member 15 is preferably made by the blow method and comprises, as seen in FIG. 6, a bottom or base 18 from the periphery of which upstands the wall 19 terminating at its upper end in an inwardly, upwardly, slanted top 20 having upstanding therefrom, substantially centrally thereof, a collar 21 provided centrally thereof with an opening 22. As shown in FIGS. 2 and 5 the outer member 15 is circular in plan but the same maybe made to simulate a square or any other construction as desired and utility may dictate.

In general, the wall 19 of the outer member is of relatively small and substantially uniform thickness upwardly of the bottom or base 18 having substantially midway of the height of the said wall a contoured reduced diameter portion, indicated in general by the reference numeral 23. While this contoured portion 23 is described and illustrated as substantially midway ofthe height of the outer member, said portion 23 may be located substantially anywhere between'the top and bottom of said outer member wall.

jecting therefrom a flange-like portion 28 that terminates at the upper end of an inwardly, upwardly extending annular sleeve 29 that eventually forms the upper end of the outer member lower part. The lower end of the said sleeve 29, in reality a short truncated cone, terminates in the upper wall 30 of an inwardly projecting circui I ferential slot 31. The said upper wall 30 of the slot 31 terminates in the rear downward wall 32 of said slot which in turn terminates in the outwardly projecting lower wall 33 of said slot, The said slot lower wall 33 terminates in the outer member lower part wall 19.

At, preferably, diametrically opposite points on its diameter the narrow band 24, see FIGS. 6, 9, l and 11, is provided with an outwardly projecting hollow lug 34 which, in effect, eliminates the horizontal flange 27 at said diametrical points and provides a key seat 35, see FIG. 11, as will presently be made clear. Similarly, the slot 31 at diametrically opposite points on the diameter thereof and in vertical alignment with the shallow band lugs 34 is provided with outwardly extending hollow lugs 36, with said lugs located directly below the narrow band hollow lugs 34. The said hollow lugs 36, see FIG. 11, includes a lateral wall 37 outwardly projecting from the base or rear wall 32 of the said slot 31 together with a second or spaced outwardly projecting wall 38 joined with the first wall 37 by a connecting wall 39.

For purposes of ornamentation the said outer member lower part 26 is provided vertically thereof with a plurality of flutes 40 which may take the form illustrated in the drawings or said ornamentation may take any other form or be completely eliminated from the said outer member,

It should be noted that the hollow lug 34 in the narrow band 24 has its base member, indicated in FIG. 9 by the reference numeral 41, as replacing the narrow band 24 and at a point closely adjacent the outer wall 19 instead of somewhat remotely inwardly thereof as illustrated in FIG. 7.

The said upper part 25 of the outer member outwardly of the central opening of its collar 21 is provided with a flange 42 having at diametrically opposite points inwardly extending recesses 43, for a purpose subsequently to be made clear. Further the said outer member upper part 25 is provided, preferably, just below its slanted top 20, with inwardly formed sockets 44 to provide a means for attaching to the completed container a carrying means or handle.

After the outer member has been formed as above described and disclosed in FIG. 6 the same is separated into its upper and lower parts by means of a saw cut or cuts, as on the lines 45 and 46 on FIGS. 6 and 7, said .cuts may be effected by a single tool which removes the material between the said lines 45 and 46. By this construction, and as seen in FIGS. 3 and 7, the upper part 25 of the outer member 15 terminates at the upper end of the sleeve or narrow band 24 and with the inwardly projecting flange 27 at the lower end of its outer wall 19, while the lower part 26 of the said outer member 15 has its upper edge at the upper end of the inwardly, upwardly inclined sleeve or upper end of the short truncated cone 29. The upper end of the said sleeve 29, or truncated cone is of such a diameter, or dimension, that it is less than the diameter or dimension of the opening through the flange 27 wherefore said upper end ofthe sleeve 29 4 readily enters through said inner diameter of the inwardly projecting ledge as will be presently made clear.

The inner member or container 16 similar to the outer member is, preferably, formed by the blow method, and is provided with a bottom 47, see FIG. 3, from the periphery of which, substantially normal thereto, upstands the wall 48 of relatively small thickness and with said wall terminating in a top 49 inwardly, upwardly, inclined to a sleeve 50. Upwardly of the sleeve 50 the inner container has upwardly projecting therefrom a neck 51 of a diameter somewhat less than the sleeve diameter 50.

The sleeve just below the neck is provided with an inwardly projecting circumferential groove 52. The said groove at diametrically opposite points is eliminated or bridged over as 53 in FIG. 3, which, in effect, see FIG. 4, provides a hollow lug 54 at said diametrically opposite points in the neck groove 52. The neck 51 has formed on its exterior surface threads 55 co-operating with similarly formed threads of the closure cap 17 and whereby said closure cap is secured to the said inner container.

In practice the external diameter of the inner container sleeve 50 is somewhat greater than, the internal diameter of the outer member collar opening 22 wherefore a close fit of these parts is effected upon assemblage requiring considerable pressure to cause the passing of said sleeve 50 through the said opening 22, as will presently be made clear.

After the outer member 15 has been formed as illustrated in FIG. 6 and cut to provide the upper part 25 and lower part 26, as illustrated in FIG. 7, the inner container is assembled with the outer member upper part 25 and the lower part 26 of theouter member is then assembled with the outer member upper part. The assembling of the inner member or container 16 with the outer member upper part 25 consists in passing the inner member or container neck 51 through the opening of outer member collar 21 and then forcing the sleeve 50 of said inner member or container through the said opening in the outer member collar 21 until the flange 42, inwardly projecting from the collar 21 is disposed within the inner container circumferential groove 52. In order to assist in the assemblage of these parts the inner container neck 51 and sleeve 50 are joined to one another by an upwardly, inwardly, inclined band 56 which acts as a cam in connecting the parts. The said inner member or container 16 is now suspended substantially centrally of the outer member top part and since the inner container 16 has an external diameter and a height considerably less than the internal diameter and height of the outer member 15, a considerable space 57 is provided between the wall 19 of the said outer member upper part 25 and the correspondingly opposed wall 48 of the inner member or container.

It should be noted, particularly from FIGS. 12 and 13, that the groove 52 is somewhat wider than the thickness of the flange 42 which is projected thereinto so as to permit ready connection of these parts. However, the groove 52 at diametrically opposite points, radially angularly related to the lugs 51, is partially closed by an upstanding lug 58, see FIG. 13, from the base or bottom 59 of the groove 52. The space between the upper end of the lug 58 and the top wall 60 of the groove 52- is such as to readily admit the flange of the outer member collar.

By this construction there is prevented any play of the flange within the groove while, as noted above, the flange and groove are in the main readily associated with one another.

The lower part 26 of the outer member 15 is now assembled with the upper part 25 by inserting the upper end of tapered sleeve portion or truncated cone 29 of the lower part 26 within the opening of the inwardly projecting flange 27. This assembling is facilitated by the fact that the upper surface of said sleeve or truncated cone 29 acts as a cam face, see FIG. 7, for outwardly pushing the said flange 29 so that the parts telescope with respect to one another. This telescoping of the parts continues until the said flange 29 of the outer member upper part 25 snaps into the circumferential groove or slot 31 of the lower part 26. The parts are now locked in operative relation with one another without danger of separation while in use. The space 57 between the wall 48 of the inner member or container 16 and the wall 19 of the outer member lower part 26, as well as the above noted space between the wall of the inner member or container and the outer member upper part are packed with suitable insulation 61 for insulating the interior of the container 16 against transfer of heat and cold to the atmosphere exteriorly of the outer member.

The insulation 61 in the space 57 may take the form of the usual sheet or blanket insulating material which would be wrapped around the inner container at the time it is being assembled with the outer member upper part 25 and before the connection of the outer member upper and

lower parts

25 and 26. Preferably however, the insulation would take the form of a foam type which is well-known and consists essentially of mixing two liquids, such as toluene and di-isocyanate. In other words, after the inner member or container and outer member upper part have been associated with one another the two liquids, in proper quantities, are placed in the space 57 and then the outer member lower part operatively connected with the upper part.

The chemical reaction of the insulation, or foam, forming liquids commencing substantially immediately upon their association and continues until the said chemical reaction has effected all of the liquid and which means that the entire space 57 is taken up by the said foam. The foam hardens to a substance generally referred to as foam plastic and has a definite shape and rigidity. This action, therefore, results in the entire space between the outer member and the inner member or container having a solid wall of insulation and which permanently, further, locks the outer member lower part sleeve or truncated cone 29 in operative relation to the said outer member upper part inwardly projecting flange 27 for thereby further insuring said parts against separation from one another.

In practice and before the outer member upper and lower parts are interconnected with one another a preformed disc or block 62 of said heat insulating material, foam plastic, for example, is placed between the spaced bottoms of the said inner member or container and outer member lower part.

In assembling the inner member or container 16 with the outer member upper part 25 care must be exercised to align the inner member or container groove bridges or lugs 53 with the recesses 43 in the outer member collar flange 42 otherwise these parts cannot be operatively connected with one another. The said lugs 53 and recesses 43 form a key or lock to prevent relative rotation of the said inner container and the outer member upper part wherefore said parts are locked in operative relation to one another.

Similarly, care must be taken in assembling or connecting the outer member upper and lower parts and the hollow lug 34 of the narrow band 24 must be aligned with the recesses 36 formed in thercircumferential slot or groove 31. The said recesses 36 and hollow lugs 34 function to locate the said top and bottom parts of the outer member with respect to one another and at the same time provide key means to prevent relative rotation of these parts.

As intimated above a handle or carrying means is provided for the jug or container and which means conveniently takes the form of a wire bail handle. As shown, particularly in FIGS. 1 and 2, the bail handle includes a body or carrying portion 63 from the opposite ends of which depend

arms

64 and 65 each having its free ends inturned as trunnions at 66 and 67. The inturned endsortrunnions 66 and 67 are respectively inserted in a socket 44 of the outer member upper part 25 whereby the handle may be positioned as in FIG.

1 for transporting purposes or may be laid onto the outer member top 20 for storage purposes, all as is well-known.

The foregoing discloses a multipart outer member with the inner container suspended centrally thereof through a peripheral groove or slot in the inner container and a supporting flange on the outer member and including means associated with said groove or slot and flange to prevent relative rotative movement therebetween. It is believed obvious that such suspending and interlocking means may be employed with substantially single structure outer member and an inner container. In the modification disclosed in FIGS. 14 to 17, inclusive, such a specific device is illustrated.

Specifically, and as shown in said FIGS. 14 to 17, use is made of the inner container 16 together with an outer member of unitary construction. Generally, the jug of FIGS. 14 to 17 comprises an outer member 68 which encloses said inner container 16 telescoped with one another through an opening 69 through the lower end of said outer member with opening 69 closed by a supporting and closing bottom member 70.

The outer member 68 includes a body portion 71 which as shown in FIG. 15, for example, is of angular cross-section, that is, has four sides, which though slightly outwardly rounded, or arcuate, are, substantially, at right angles to one another, thereby giving said outer container body 71 the general appearance of being square in transverse cross-section or plan. The lower ends of the walls of said body portion 71 inwardly turn to provide a shoulder 72 from which downwardly projects a sleeve 73 having the lower end inwardly turned to provide a flange 74, in turn, having formed centrally thereof the opening 69 to the interior of the outer member 68. The upper ends of the body portion sides likewise inwardly, and slightly upwardly, project to form a top 75 substantially centrally of which rises a neck 76 terminating in an inwardly projecting radialflange 77 with an opening 78 substantially centrally thereof.

The said outer member body 71 when being formed is formed by the blow method and at this time is provided with a bottom or closure portion and which, as will presently be made clear, in part, provides the inward radial bottom flange 74. After the said enclosing member 68 has been completely formed the said bottom or closure portion is circularly cut out to thereby provide the opening 69 through which the inner container 16 is inserted within the outer enclosing member 68.

The upwardly extending collar or neck 76 may be provided at two diametrically opposite points with outwardly projecting

hollow lugs

79 and 80 through the outer vertical wall of each of which there is provided an aperture, respectively, 81 and 82, for a purpose subsequently to be described.

The inner member container per se, is, as noted above, preferably, circular in cross-section or plan and of a diameter to pass freely through the opening 69 at the bottom of the outer member. The lower end of the inner container Wall 48 is upwardly of the lower ends of the outer member walls wherefore the bottom 47 of the said inner container has its bottom upwardly spaced from the bottom of said outer member.

It should be noted, and as intimated above, the said inner container and outer enclosing member are each formed of synthetic resin, which may conveniently take the form of linear polyethylene, with the walls of a relatively thin cross-section wherefore a certain amount of flexibility andbend results in the parts.

.After the outer. member 68 has been formed or blown and the said outer member has had its bottom cut therefrom to provide the opening 69, and after the inner container 16 has been formed or blown the said inner container is inserted through the said outer member bottom opening 69 and pressure applied to the parts to cause theinner member sleeve 50 to be forced through the outer member collar flange opening 78 until the 7 collar flange 77 is aligned with the inner container sleeve circumferential groove 52 whereupon said outer member collar flange snaps into said groove to operatively suspend the inner container within the outer member.

It is to be understood that the said outer member collar flange 77 is provided with the keyway 51 to key said inner container and outer member to one another against relative angular or rotative movement.

From the foregoing, it will now be apparent that there has been provided a container including substantially unitary outer member 68 and an inner member or container 16 and with a space 57 between the body portions thereof. In order to fully insulate the said parts from one another the said space 57 is filled with heat insulating material, such as spun glass. It should be noted that this insulating material may take any desirable form such as granular, preferably, however, the said insulating material will take the form of plastic foam insulation, as above specifically pointed out.

The opening 69 in the bottom of the outer member is closed, as noted above, by the supplemental supporting bottom member 70, illustrated in operative position in FIG. 14. As illustrated, the said bottom member 70 is circular in plan including a central body portion 83 having an upstanding peripheral sleevelike wall 84 terminating in an outward radial flange 85. The sleevelike wall 84 is formed to a diameter closely approximating the internal diameter of the opening 69 while the radial flange 85 outwardly projects therefrom. The supporting bottom body portion 83 is reinforced by having the major central portion thereof inwardly and upwardly projected, as at 86, and with said central portion 86 having downwardly and outwardly inclining peripheral connection portions 87 which result in the bottom 83 having an active ringlike support portion 88.

In practice, since the said bottom member is formed of relatively flexible plastic, and after the inner container and outer member have been assembled as above set forth, the said bottom closure 70 is subjected to pressure suflicient to deform and flex the same to the point that its rim or flange 85 may be pushed through the opening 69, whereupon, and due to its normal springy nature and the removal of the deforming pressure, the said bottom closure 70 straightens itself out to have its said flange 85 arrange itself on the inner surface of the body member flange 74, and thereby be operatively associated with the said outer or enclosing member.

In practice, and before the said bottom closure member 70 is positioned, a spacing member is disposed in the space between the said bottom closure member 70 and the bottom 47 of the inner container. This spacing member is in the form of a round block, indicated in the drawings by the reference numeral 88, and, as noted above, is formed of foam plastic.

In order to transport the insulated container there is provided a handle, indicated in its entirety by the reference numeral 89, comprising a grip or body portion 90 from the opposite ends of which depend

arms

91 and 92 with said arms having, respectively, apertures 93 and 94 at their lower free ends. As will be noted, particularly in FIG. 14, the

hollow lugs

79 and 80 extend for the entire height of outer member collar 26 and through which extends the

apertures

81 and 82. The carrying handle arms apertures 93 and 94 are adapted, respectively, to be axially aligned with said

apertures

81 and 82 and to have extending through said aligned apertures pivots 95 and 96 and whereby the handle 89 may be swung in either direction from the position thereof illustrated in said FIG. 14.

In practice the carrying handle 89 is attached to the outer member before the connection therewith of the inner container. In other words, after the said outer member 68 has been molded and its opening 69 cut therein the pivots or rivets 95 and 96 are inserted through the

apertures

81, 82, 93 and 94 with said rivets each having its head 97 in the space 98 conveniently provided between the vertical walls of said hollow lugs 79 and and the opposed wall of the inner container neck 50. After the rivets have been positioned the outer ends thereof are upset to provide heads 99. 7

From the foregoing, it is believed now evident that there has been provided an insulated picnic jug or container that accomplishes the objects initially set forth.
