16 Claims. (Cl. 222-131) This invention relates to improvements in an insulated container for use as a jug for maintaining liquids in hot and cold condition for a reasonable period of time.

This invention relates particularly to a means for dispensing the liquid from the container particularly when the container is in the form of a picnic jug which is generally employed for hot or cold liquids and particularly as drinks.

The principal object of the present invention is the provision of means for dispensing the liquids from the jug without having to uncap and pour said liquid content and whereby a better control of said dispensing is obtained.

Another object of this invention is the provision of a pump for use with picnic jugs operable through a simple squeeze bulb whereby the said dispensing may be etfective in a more expeditious manner than heretofore.

Another object of this invention is the provision of a squeeze bulb pump for accomplishing the foregoing objects and in which the liquid is retained in a suitable compartment and not in the squeeze bulb during the dispens Fig. 2 is a top plan view of the insulated container of Fig. l.

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

The insulated container as herein disclosed comprises an outer body member or shell 15 in the form of a hollow cylinder similar to the cylindrical body member of an ordinary can or container, having its upper end open as at 16. The lower end of the body member 15 is outwardly turned to form a hook 17. adapted to interfit with a complementaryhook 18 formed at the periphery of the container bottom 19. The bottom 19 is attached to the body member or shell 15 in the same manner as the end closure for a can.

The upper end 16 of the body member or shell 15 is outwardly and downwardly bent as an angular flange 20 through which the said upper end 16 of the body member or shell 15 is closed and through which the said shell 15 has secured thereto an inner container suspending mechanism indicated in general by the reference numeral 21..

The inner container 22 is in the form of a glass bottle or jar, such as is well known as a Mason fruit jar. Such a jar is provided with a bottom 23 from the periph cry of which upstands the wall 24 and the said bottom may be circular in plan, but is, preferably, and as illustrated in Fig. 4, substantially rectangular in plan and has a wall 24 upstanding from each side or edge thereof.

The said inner container or jar 22 terminates at its upper end in a neck 25 having a radial flange 26 at its lower end. Upwardly of the radial flange 26 the neck 25 is provided with an outwardly projecting spiral rib which forms in eflect a screw thread 27.

In the mounting of the inner container or jar 22 within the shell 15, use is made of the radial flange 26 for attaching the said inner container or jar 22 to the suspending device 21.

Specifically, the suspending device 21 comprises a pairof telescopic clamping members, an upper member 28 and a lower member 29, with said upper member 28 comprising a substantially horizontal portion 30 centrally apertured as at 31. The aperture 31 has an inner diameter substantially equal to the diameter of the spiral rib or thread 27 so as to just pass thereover. The

periphery of the body portion 30 is turned on itself to form an inturned flange'32 and inwardly of said flange there is provided a downwardly disposed flange or skirt two diametrically opposite points of .the aperture 35 the said body portion, in effect a ring, 34 is inwardly notched as at 36 and 37 so that its transverse dimension, between the bases of said notches 36' and 37, will be such that the inner container radial flange 26 may be passed through the aperture 35 to have its'body-portion ring 34 therebelow, as will presently be made clear. The said lower clamping member 29 has a further ring like portion 38 that is downwardly spaced from and in a plane below, the body portion ring 34 as clearly illustrated in Figs. 3 and 5. The lower clamping member 29 has the intermediate portion of its body portion downwardly inclined as at 39 for connecting the spaced horizontal ring like body portions-34 and 38 with one another.

The outer periphery of the body portion ring 38 is upwardly turned" as at 40 to form a flange, or wall, of the dish and has an inner diameter to frictionally and closely receive the downwardly disposed flange or skirt 33 of the top clamping member 28.

The upper end of the flange or-wall 40 is outwardly turned as a ring 41 adapted to contact and underlie the upper clamping member inturned flange 32 as clearly illustrated in Fig. 5. The outer periphery of said lower clamping member 29 has its outer periphery down turned as a skirt 42 to provide a channel 43 in said lower clamping member at its outer edge or periphery, The said channel 43 of the lower clamping member 29 has the distance between the inner surface of the skirt 42 and the opposed surface of the flange, or wall, 40 is slightly less than the distance between the outermost point 44 of the inclined or angular flange 20 and the inner surface of the shell 15, wherefore, the telescoping of the upper and lower clamping members are retained in operative positionsand' separable from one another only upon the use of force.

Disposed on the upper face 45 of the inner container radial .fiange 261is' a'rubber washer or gasket 46 having a diameter 47 equal, substantially, to the diameter of the container'neck 25, see Fig. 10, so as to closely engage said neck when lying on the said face 45 of the radial flange 26; since the said washer or gasket 46 is formed of flexible material, rubber, it can be stretched over the spiral rib or thread 27 to be disposed as illustrated in Figs. 3 and Lyingagainstthe under surface 48 of the inner container radial'flange 26 is a second gasket or washer 49, similar to :the. gasket or washer 46, formed of rubber and having an aperture 50, see Fig. 10, again of a diameter substantially equal to the diameter of the inner container neck 25 and, again, since the gasket 49'is formed of flexible rubber,is stretchable to pass over the inner container radial flange '26 to be disposed therebeneath and against its said under surface 48.

It should be noted that the exterior diameter of the upstanding flange 40 of the lower clamping member of the suspending means-is such that it tightly and frictionally enters the open upper. end of the jug outer member or outer shell 15.

In assembling the insulated container, the said inner container first has the lower clamping member 29 mounted in operative position by having inserted through its aperture the inner container radial flange 26, this being accomplished, as noted above, by angularly positioning the said member on the inner container. neck and with the radial flange 26 thereon pushed through the notches 36 and 37 whereupon the said clamping member 29 may be straightened up and temporarily retained on the flaring portion of said inner container that is located below its neck 25. The lower gasket or washer 49 is now mounted in position to underlie thexsaid inner container 43 radial flange 26 'andbe disposed against the. lower surface 48 thereof. The upper gasket 46 is nowmounted in position to lie on top of the said inner container radial flange 26 and hug the upper surface 45 of the flange 26. The suspending means top clamping member 28 now has the inner container neck inserted through its aperture 31 whereupon the said inner and outer clamping members 28 and 29 are telescoped by inserting the depending flange 33 of the upper member within the upstanding flange 49 of the lower member and said parts telescoped until their respective flanges or rings, 32 and 41, are in face contact, as illustrated in Figs. 3 and 5. It should be noted that the frictional engagement of these parts is such that an instrument or tool is necessary to be inserted between said flanges or rings 32 and 41 in order to separate the same after they have been operatively associated with one another.

It should be further noted that the telescoping of the suspending means upper and lower clamping members to the point of flanges or rings engagement effects a tight clamping engagement of the portion of the upper member body 30 that is immediately outwardly of its aperture 31 on the upper gasket 46 and, that a similar clamping action is effected through the inner body portion ring 34 of the lower clamping member with the lower gasket 49, all as clearly illustrated in Figs. 3 and 5. The clamping engagement of these parts is such that said upper and lower gaskets 46 and 49 are compressed to form a liquid and air tight joint around the inner container neck.

It will now be noted that the inner container is securely attached to the suspending mechanism and the said parts are inserted as a unit within the outer container. Before the insertion, however, of the inner container within the shell 15 a layer of heat insulation, for example, in the nature of sheet spun glass, 51 is first deposited within the shell 15 against the inner face of the bottom 19. The inner container or glass jar 22 is then completely wrapped or enfolded in a sheet 52 of similar heat'insulating material whereupon the said inner container is inserted within the outer container or shell 15.

The connection of the parts with one another is by the frictional insertion of the I inner container suspending means flange or Wall within the open upper end 16 of the said shell 15, width: insertion'of the inclined or angular flange 20 of the outer container shell 15 into the suspending device channel 43. It should be noted that considerable force is necessary to insert the suspending against the bottom of the outer container shell.

device through its lower clamping member 29 within the shell 15 and the inclined or angular flange 20 in the channel 43, that such frictional resistance exists between the suspending device and outer shell that the use of force is needed for subsequently separating the parts when desired. In order to remove the inner container from the outer container shell, the inner container neck is grasped in one hand, or the hand is inserted into the neck opening, and pressure is exerted through the other hand This pressure may be in the nature of a slap through the open palm of said second hand.

The parts are so related to one another that upon the insertion of the inner container suspending device to the point where the radial flange or ring 41 engages the upper end of the shell 15 the insulating material 51 and 52 is in contact with the parts and under a slight compression.

It will be understood that the inner and outer containers are separated from one another only when it is necessary for the cleaning of the interior of the outer shell and the exterior of the inner container or when it is necessary to replace said inner container due to breakage thereof.

It will be readily understood that the inner container 22 has its neck centrally apertured for the filling and discharging thereof and which aperture is closed by a readily removable closure cap, indicated in its entirety by the reference numeral 53.

The closure cap 53 is provided with a body portion 54 from the periphery of which depends a skirt 55 having inwardly projecting lugs 56 that cooperate with the inner container screw threads 27 for securing the parts to one another. Disposed on the under surface of the closure cap 53 is a compressible gasket or washer 57 for sealing the closure cap to the upper end of the inner container neck 25.

The closure cap 53 has secured thereto a pump mechanism indicated in its entirety by the reference numeral 58 through which the contents of the inner container 22 is discharged as desired. It will be understood that the inner container contents is generally in the form of a beverage, such as hot coffee, cold lemonade, or the like which is to be dispensed in amounts of cupfuls or glassfuls.

It will be appreciated that the dispensing of the inner container contents provides a void therein which must be supplied with air and since the dispenser is relatively completely sealed against leakage the said air is supplied through an aperture or duct 103 formed in the body portion 54 of the closure cap. As seen inFigs. 1 and 5, for example, the said aperture or duct 103 is located in the said body portion 54 to be between the outer surface of the pump housing 59 and the inner surface of the opening through the inner container neck 25. While the said aperture or duct .103 is essential to permit ingress of replacement air, if the said aperture or duct 103 is allowed to remain open continuously it would permit the cold content of the container to be warmed up by said atmospheric air, or in the event the inner container content were a hot liquid, such as coffee, and there would be a continuous escape of heat from the inner container and resulting in said hot liquid cooling to an undesired point.

To prevent the continuous flow of air through the port or aperture 103 use is made of the closure cap sealing gasket 57 to normally seal or close the same. To this end the said compressible gasket or washer 57 is provided with a valve or flap 104 inwardly projecting from the said gasket to underlie the port or aperture 103, as clearly illustrated in Fig. 11.

In order to insure the proper positioning of the flap or valve 104 with respect to the aperture 103, the gasket 57 is provided in one point of its outer periphery with a seat or depression 105 adapted to receive an inwardly projecting lug 106 from the closure cap depending skirt 55, all as clearly illustrated in Fig. 11.

It is believed that the operation of the valve'104 is readily apparent since a discharge of the contents of the inner container by the pump mechanism 58 presently would be described in detail, causes a deflection of said valve or flap 104 to the dotted line position 107 illustrated in Fig. 12 and upon cessation of the operation of the pump mechanism the said valve or flap will return to its normal sealing or closing position. It will also be noted that the closure cap lug 106 prevents the displacement of the valve or tab 104 when the said closure cap is being screwed home.

The dispensing pump mechanism 58 comprises a housing or body member 59 of the same cross section as the opening through the inner container neck and is provided below its upper end with a shoulder 60 underlying a lip 61 on the closure cap body member and through which said parts are cemented or secured to one another. Upwardly of the shoulder 60 the body portion 59 tapers as ,at 62 terminating in a concaved top 63 through which is formed an opening 64.

Disposed on the upper surface of the concaved top 63 or seat 65 of the pump body concaved top 63, is a squeeze bulb 66 having depending from one point thereon a neck or protuberance 67 which is centrally apertured, to communicate with the interior of the squeeze bulb, as at 68. The protuberance 67 has its outer end enlarged as at 69 thereby underlying the pump body top 63 outwardly of its aperture 64 and effecting a secure connection of the squeeze bulb and pump body housing 59. It is to be understood that the squeeze bulb 66 is formed of pliable rubber or some similar material capable of being deformed under pressure of the hand and finger and returning to its normal position upon release of said pressure.

Formed within the pump body or housing 59 at a point- -adjacent its inner periphery,-as illustrated in Figs.

5 and 8, is a well 70 having its lower end formed as an inwardly projecting flange 71 centrally apertured as at 72. The well 70 is, in effect, a trap and houses a displaceable valve 73 herein illustrated as a cylindrical body member formed of material incapable of floating in liquid.

The upper end of the well or trap 70 is open to receive a depending hollow lug 74 at the inner end of a discharge spout 75. The spout 75 has a central aperture 76 communicating with the aperture of the lug 74 and with said inner end of the aperture 76 closed by a back end 77 which is formed with a concaved upper surface and conforms to the pump housing concaved top 63 and provides a continuation of said top concaved seat 65 for receiving the squeeze bulb 66.

The discharge spout 75 at its outer end is downturned as at 78 and which downturned end is in part formed by the member most clearly disclosed in Fig. 9. As shown in Fig. 9 this member 79 has a curved body portion 80, curved in accordance with the downturned portion 78 of the spout. At its inner end the said body portion 80 has depending therefrom a U-shaped dam 81 with a central aperture 82. The dam 81 has a depth to rest on the bottom surface of the spout central passage and lateral surfaces to engage the inner surfaces of said spout, all as clearly illustrated in Fig. 6 and the purpose of which will subsequently be made clear.

The pump housing 59 has its lower end open and has inwardly projecting therefrom a rib 83 constituting a screw thread and which lower open end of the body portion is closed by a cap 84. The cap 84 includes an outwardly projecting flange 85 from which upwardly proj'ects a cylindrical sleeve or ring 86 exteriorly grooved to provide a screw thread for the pump body housing thread 83 and through which said parts are secured to one another. Below the flange 85 the cap 84 is provided with a bottom 87 which is dished toward its center terminating in an aperture 88 substantially centrally of a depending lug 89. The lug 89 is provided at the upper end of its aperture 87 with a valve seat 90 on which gravity valve 91 seats. The valve 91, similar to the valve 73, is formed of material that will not float in liquid; it has been found that the said valves may conveniently take the form of the well known glass marbles.

The cap bottom 87 has depending from each side of the lug 89 ears 92 and 93 through which the said cap may be screwed to operative position.

Secured to and depending from the cap lug 89 is a conduit 94 which conveniently takes the form of a flexible hose either of rubber or one of the newer synthetic materials. The said conduit 94 depends to a point substantially adjacent the bottom 23 of the inner container as clearly illustrated in Fig. 5. In order to insure a tight connection of the conduit 94 and the cap lug 89 the said lug is provided wtih an outwardly projecting head 95 for effecting a tight connection of the flexible hose or conduit therewith.

The modification illustrated in Figs. 13, 14 and 15 is concerned primarily with the dispensing nozzle on discharge spout 75. The spout 75 is formed of two castings or moldings 96 and 97 respectively provided with an interfitting tongue and groove 98 to insure a liquid proof joint upon securement of said moldings to one another. The assembled spout 75' is provided at its inner end with the depending hollow lug 74 through which it is attached to the pump well or trap 70.

As clearly illustrated in Fig. 13 the modified spout body portion is upwardly and outwardly disposed to a point beyond the container body portion or shell 15 at which point the said spout levels ofi as at 99 and has a discharge opening 100, the discharge opening, being integral with the lower molding 97.

With this construction the anti-drip dam or block 81, illustrated in Figs. 5, 6 and 9, may be dispensed with since upon cessation of a pumping action through the bulb 66, as above described, theliquid .inthe spoutu75',

due to the fact'that said spout=is downwardly inclined,

tween-the'piump body housing.59' and its closingcap 84". This connection,,instead, is effected by forminga countersink 101 inwardly of the open end of the pump body housing 59'" andproviding the cap 84' with an upstanding rimor flange10'2 received in said countersink 101. These parts are then cemented, or otherwise secured to one another, to make an integralior permanentstructure of the pump body housing 59' and its closure cap 84'; it being understood that the said parts are connected to oneanother after the valve 91 has been disposed therein: The modified lower closure cap 84 is illustrated in'Fig. -13 of a greater vertical dimensionthan that illustrated in Fig. wherefore the capacity of the pump body housing has been increased, but a similar capacity may be given to the closure cap 84 of Fig. 5.

While the nozzle 75, as illustrated in Figs. 5, ,6 and 9, with its anti-drip dam 81, and the nozzle 75', of Figs. 13, 14 and 15, due to its upward inclination, eifectively prevent undesirable dripping upon cessation of the actuation of the pump bulb, any tilting, shifting or jogging of the container causes the liquid trapped in said nozzle to be dislodged. To overcome this and prevent drippage from said nozzles under any circumstances the modification-illustrated in Figs. 16 and 17 may be-employed.

The check valve 73 in the above modifications illustrated in Figs. 5, 6,7, 8 and 13 is of the heavier than water type wherefore upon release of pressure, in a pumping direction, on the squeeze bulb, the negative pressure created within the container immediately draws said check valve 73 to its seat for maintaining the chamber 70 and the nozzle, connected therewith, filled wtih liquid. By substituting the check valve 108 of Fig. 16 for that above referred to, this condition is reversed.

As illustrated in said Fig. 16 the check valve 108 is formed or molded, preferably, of one of the plastics, such as polyethylene, which gives said check valve a specific gravity slightly less than that of water, or the said checkvalve 108 may be formed of wood which, again, has a specific gravity slightly less than that of water.

Upon operationof the squeeze bulb in a pumping direction, and assuming that the pump body 59' is amply supplied with liquid and its check valve M is on its seat, the liquid in said pump housing 59 is forced through the chamber 70' to and through the discharge nozzle, and at the same time raises the check valve 198 fully from its seat and floating same at the upper end of the said chamber 70'. Uponrelease of pressure on the squeeze bulb and, as noted-above, the creation of a negative pressure within the container, the liquid now in the chamber 7% and its connecting nozzle is first drawn into the pump housing 59' until the check valve 108 is seated whereupon the pump housing check valve 91 is withdrawn from its seatand'the liquid sucked from the container.

The negative pressure within the pump housing 59 will, at least, withdraw the liquid within the chamber 70' and at the same time will draw the check valve 108 to its seat. This operation will drain the nozzle to the point where, at least, there is insufficient liquid in the nozzle, and the chamber 70, to spill or drip upon movement of the container. It will be appreciated that the amount of liquid in the chamber 76 and nozzle 108, even if full, and completely sucked or drained therefrom, is out a small portion-of the capacity of the pump housing 59'- and but a small quantityas compared with the quantity ofi-liquid that will-be drawninto said pump.

housing by a single operation of the squeeze bulb, wherefore, after the chamber 70' and its nozzle 108 are sufiiciently'ernptied, thesqueeze bulb will draw into the pump housings59 from the containersufficient liquid for a subsequent'pumping operation of said squeeze bulb.

A pumping operation of the squeeze bulb to discharge liquid from the nozzle 75 drives the check valve 108 to the upper end of the chamber 70' and even into the hollow lug 74'. While the check valve 108 is of such a size that-it cannot close the entrance into the nozzle 75 it is desirable to prevent the said check valve 108 from entering the hollow lug 74, wherefore, the said hollow lug 74= is'provided with inwardly projecting lugs or stops 109 which engage the said valve 108 and arrest its move ment under the influence of the pump.

As illustrated in Fig. 16 the chamber 70 is made slightly longer with respect to its pump housing than is the chamber 70 with respect to its pump housing in Fig. 5. By this construction the chamber 70 is given sufficient-capacity to substantially empty the nozzle 75' before the valve 108 is seated to close the inlet opening 72 to said chamber 70'.

From the foregoing, it will be appreciated that there has been provided a picnic jug or the like which may have the liquid contents pumped therefrom at different times, and as needed or desired, and without opening said jug to the atmosphere to be contaminated thereby or have the temperature of the contents changed to that of said atmosphere.
