(Cl. 215-13) ABSTRACT OF THE DISCLOSURE A container including inner and outer telescopingly engaged tubular members closed at one set of corresponding ends and open at the other set of corresponding ends with the open end portion of the inner tubular member being seatingly engaged with the inner surface portions of the open end of the outer tubular member and projecting outwardly of the latter and the closed end of the outer tubular member being inwardly displaceable by an inward force directed thereon from the exterior of said body and operable, when being inwardly displaced, to at least slightly outwardly displace the inner tubular memher from the open end of the outer tubular member.

This invention relates to a novel and useful insulating tumbler assembly and more specifically to an assembly including a generally tubular outer body closed at one end and open at the other end. The assembly also includes an inner tubular member which is closed at one end portion and has its closed end portion removably telescoped into the open end of the outer tubular body with the closed end portion of the inner tubular member disposed in the closed end of the tubular body. Further, the open ends of the tubular body and tubular inner member include coacting inner and outer surface portions respectively, which are seated in frictional engagement with each other in a manner forming a generally fluid-tight seal therebetween.

At least some portions of the inner tubular member are spaced from corresponding portions of the outer tubular body constructed of deformable material and adapted to be displaced inwardly by a force directed thereon from the exterior of the body to thereby reduce the volume of the area disposed between the spaced portions of the outer tubular body and the inner tubular member. In this manner the air pressure within the area will be increased and may be utilized to eject the inner tubular member at least slightly outwardly of the open end of the tubular body member.

Further, the deformable portions of the outer tubular I body form the bottom wall thereof and are convexed downwardly whereby the convexecl portions may be readily upwardly displaced in order to increase the air pressure within the above mentioned area. Still further, the bottom of the inner tubular member is spaced only slightly above the convexed portions of the bottom of the outer tubular body thereby allowing the deformable portions of the bottom of the outer tubular body to also Contact and upwardly displace the bottom of the inner tubular member when the deformable portion is displaced upwardly.

Both the outer tubular body and inner tubular member of the assembly of the instant invention are preferably constructed of a material having low heat transferring properties such as plastic enabling the assembly to be utilized to contain either chilled or heated fluids which fluids, because of the low heat transfer properties of the outer body and inner tubular member and the spacing between major portions of the outer surfaces of the inner member and the inner surfaces of the outer tubular body, will tend to maintain their respective temperatures longer.

The main object of this invention is to provide an insulating tumbler construction or assembly that is adapted to have either chilled or heated liquids disposed therein and consumed directly therefrom by the user placing the open end of the tumbler assembly to his lips and drinking fluid from the tumbler.

Another object of this invention, in accordance with the immediately preceding object, is to provide an insulating tumbler assembly which may be utilized to contain either chilled or heated liquids to be consumed directly therefrom and which, because of its heat insulating properties and double container construction, prevents the outer surface of the tumbler assembly from sweating or the supporting surface on which the tumbler is disposed from sweating.

A further object of this invention is to provide an assembly in accordance with the preceding objects constructed in a manner enabling the inner member to be readily displaced at least partially outwardly of the open end of the outer member.

A final object of this invention to be specifically enumerated herein is to provide an insulated tumbler assembly in accordance with the preceding objects which will conform to conventional forms of manufacture, be of simple construction and easy to use so as to provide a device that will be economically feasible, long lasting and relatively trouble free in operation.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a perspective view of the insulating tumbler assembly of the instant invention;

FIGURE 2 is a bottom plan view of the assemblage illustrated in FIGURE 1;

FIGURE 3 is a vertical sectional view taken substantially upon the plane indicated by the section line 33 of FIGURE 2;

FIGURE 4 is a fiagmentary sectional view similar to that of FIGURE 3 but shown with the inner tubular member slightly outwardly displaced from the open end of the tubular body by increased air pressure within the area disposed between the spaced apart portions of the body and tubular member caused by upward deflection of the normally downwardly convex center portion of the bottom wall of the outer tubular body;

FIGURE 5 is a perspective view of a modified form of insulating tumbler assembly constructed in accordance with the present invention;

FIGURE 6 is a vertical sectional view similar to that of FIGURE 3 but of the modified form of tumbler assemly illustrated in FIGURE 5;

FIGURE 7 is a sectional view similar to that of FIG- URE 4 illustrating the manner in which the inner tubular member of the assemblage illustrated in FIGURE 5 may also be at least partially ejected from the open end of the tubular body by upward deflection of the center portion of the bottom wall of the body; and

FIGURE 8 is a top plan view of the bottom assembly utilized in both illustrated forms of the invention.

Referring now more specifically to the drawings, thenumeral 10 generally designates the insulating tumbler assembly of the instant invention. Theassembly 10 includes an outer generally tubular body referred to in general by thereference numeral 12 and a generally tubular inner member referred to in general by the reference numeral14.

Theouter body 12 includes abody portion 16 which is generally cylindrical in configuration and a bottom assembly referred to in general by thereference numeral 18. The lower end of thebody portion 16 is beveled as at 20 to define a circumfererntially extendingbead 22 and thebottom assembly 18 includes a generallycylindrical body portion 24 including a circumferentially upwardly openinggroove 26 in which thebeveled portion 20 and thebead 22 are removably interlockingly received. Further, thebody portion 24 of thebottom assembly 18 includes abottom wall portion 28 including a thick outer annularperipheral portion 30 and a downwardly convexedcentral portion 32. The tubular body 1.: is constructed of any suitable material such as plastic and has poor heat-transmitting properties. Thecentral portion 32 of thebottom assembly 18 may be deflected upwardly to the position illustrated in FIG. 4- of the drawings by applying an upward force on the center thereof.

The innercylindrical member 14 includes abottom wall 34 closing its lower end and its upper open end is provided with a circumferentially extendingshoulder 36 which faces toward the closed end of themember 14 and is abuttingly engageable with the upper end edges of thebody portion 16 when themember 14 is telescoped within thebody 12 in the manner illustrated in FIG. 3 of the drawings.

Thebody 12 includes an outwardly projecting fixedbailtype handle 38 disposed in an upstanding plane and which may be readily grasped by the user of thetumbler assembly 10 when lifting the latter to drink therefrom.

The outer surface portions of theinner member 14 disposed below theshoulder 36 are tightly telescoped within the upper end of thebody 12 and forms a generally fluidtight seal therewith. Accordingly, if cold liquids are poured into theinner member 14, the air within the area disposed between the spaced portions of thebody 12 andinner member 14 is chilled thus creating a partially vacuum which tends to tightly draw theinner member 14 into full seated engagement within thebody 12. In order to provide a means whereby theinner member 14 may be at least partially ejected from the open end of thebody 12, thecentral portion 32 of thebottom wall 28 may be deflected upwardly to the position illustrated in FIG. 4 of the drawings thereby reducing the volume of the area between the confronting surfaces of thebody 12 andinner member 14 so as to increase the air pressure within the area and thereby forcibly eject, by increased air pressure, theinner member 14 from thebody 12.

With reference now more specifically to FIG. of the drawings, there may be seen a modified form of insulative tumbler assembly generally referred to by the reference numeral and which includes an outer tubular body generally referred to by the reference numeral 12' substantially identical in construction to thetubular body 12 and which has its component parts designated by prime numerals corresponding to the numerals given the same component parts of thebody 12.

The inner tubular member of the tumbler assembly 10' is generally referred to by thereference numeral 14 and includes abottom wall 34 corresponding to thebottom wall 34 closing the lower end of thetubular member 14 and which is seatingly received in the downwardly convexedcentral portion 32 of thebottom wall 28 and engageable by the latter when thecentral portion 32 is upwardly deflected as illustrated in FIGURE 7 to assist the increased air pressure in the space between the body 12' and themember 14 in at least partially ejecting themember 14 defines an outer circumferentially extending shoulder 36' corresponding to theshoulder 36 which abuts against the upper edges of the open end of the tubular body 12'. However, the tubular member 14' extends upwardly from theshoulder 36 and terminates in an outturned and downwardly directedportion 40 which overlaps the upper end portions of thetubular body 12.

The operation of the insulating tumbler assembly 10' is of course substantially identical to the operation of theassembly 10 except that the freelower end portions 42 of thebackturned portion 40 also form a generally fluidtight seal between the innertubular member 14 and the outer tubular body 12'. Thus, a double seal is formed between thetubular body 12 and theinner member 14.

When it is desired to eject the tubular member 14' from thebody 12, it is merely necessary to upwardly deflect the central portion 32' of the botom wall 28' whereby increased air pressure within the area disposed between the innertubular member 14 and the outertubular body 12 will cause the inner tubular member 14' to be at least partially ejected outwardly of the open end of the tubular body 12'. Further, the central portion 32' may be further upwardly deflected so as to abut thebottom wall 34 and thereby physically assist in at least initially ejecting the innertubular member 14. Finally, the innertubular member 14 may be increased in length so as to have its lower end cradled by the outer peripheral portions of thebottom wall 28 and the central portion of itsbottom wall 34 engageable by thecentral portion 32 of the bottom wall 23.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
