Y Y l y Thisinvention relates to a lunch box and it is one object of the invention to provide a lunch box, comprising a body having associated therewith, a lower section constituting a bottom f-or the body and having telescoping engagement with the body, so that it may be shifted vertically to adjusted positions and thus increase the capacity of the lunch box which, when empty, may be reduced to its normal size and conveniently carried by a person. k

\ Another object of the invention is to provide aV lunch box wherein, an auxiliary lower section ts into the body of the box through the open lower end thereoand carries arms movable into and out of position for engaging selected ones of vertically spaced stops projecting inwardly from walls of the body and thus allowing the depth of the lunch box to be progressively increased and the lower section firmly held in its adjusted position.

Another object of the invention is to provide This improved lunch box has a body I, which is preferably formed ofI sheet metal but may be formed of other suitable materials. This body isV portions of the side and end walls of the body are offset inwardly to reducey the dimensions of the the lunch box with an adjustable lower section ,y n

lower section. A handle I4 is connected with the` carrying a plurality of securing members, which are formed-of resilient metal and are simultaneously moved to a retracted position by a single adjusting member having cams for engaging both of the securing members.

Another object of the invention is to provid the lunch box with a dome-shapedcover having improved means carried thereby for securing a vacuum bottle in the cover.

Another object of the invention is to provide an improved latch for releasably securing the coverV closed.

Anotherobject of the invention is to provide a luch box having an auxiliary lower section for its bodywhich may be entirely removed there- Fig. 3 is a fragmentary sectional view taken i' vertically along the line 3-3 of Figure 2, the extended position of its lower section being indicated by dotted lines. l l

Fig. 4 is a perspective view showing the'securingrmeans for holding the lower section of the lunch box in an adjusted position.

Fig.` 5 is a perspective view of the means for securing a vacuum bottle in the cover of the lunch box.

to be swung downwardly into position to be` upperend ofthe body and allow a cover 5 con-` nected with the rearwall 3, by hinges 6, to be` easilymoved into position for closing the upperl end or top of the body I. A handle l is provided upon the cover for carrying the lunch box and in order to releasably secure the cover closedy there has been provided a latch 8 carried by the cover and movable into and out of engagement with .a keeper 9 carried by the front wall 4.

Anv auxiliary lower section IB is associated with the body I and has a bottomll and side walls` I2fand end walls I3, the lower section being of suchdimensions that .its ywalls will fit snugly within the body and thus establish telescoping engagementbetweenthe body and the auxiliarybottom I Iby hinges I5 and is normally secured in a folded.- position against the bottom by a latch I6 from which it is readily detachable when it is E grasped and the lower section drawn downwardly Normally the lower section II! is in a retracted position within the body and in order to allow ,Y this lower section tovbe releasably secured in its retracted position and also rin an'extended position,`there have `been provided securing arms I8.

formed from strips of resilient metal. `These inetal strips have their lower portions bent to form feet I 9, which are welded to each of the end walls I3, ofthe lower section, and referring to Figures 2, 3 and 4 of the drawings, it will be seen that the companionl securing arms are spaced from each other transversely. of the walls to which they are secured and extend vertically with their upper portions projecting above the wall and bent at their upper ends .to formpbills I9' which pro` ject outwardly from the walls of the auxiliary section. Bars 20 are mounted vertically against inner surfaces ofthe end walls 2 of the body I and. these-bars are formed from m'etal strips Fig. 6 is a view taken vertically along the line 6 6 of Figure 2 upon an enlarged scale and showing the latch for holding thecover of the lunch boxv closed partially in section and partially in elevation.

.i besupported ina lowered orextended position which arecrimped to .form abutment ribs 2|, spaced vertically from each other. When the bills I9 ofthe arms @or latches I8 are engaged over the ribs at upper ends of `the bars 20, the auxiliarylowersection of kthe body will be held in a retracted position which is itsnormal position and when the bills are engaged with selected ones of the other ribs theauxiliary section will
