Application filed March 19, 1923.
To all whom it may concern:
Be it known that I, EDWARD E. GRAY, a" citizen of the United States, and a resident of Plano, in the county of Kendall and State of Illinois, have invented an Improved Lunch Box, of which the following is a specification.
This invention relates to lunch boxes.
The object of the invention is to provide means for supporting a thermos bottle within the cover of the box, constructed and arranged to prevent accidental displacement thereof when the cover is closed, together with improved locking means for securing the cover of the box in closed position, which will be particularly positive, thus preventing accidental opening of said box with probable spilling of the contents thereof.
To efiec't the foregoing object, a lunch box of my invention comprises the various features, combinations of features and details of construction hereinafter described and claimed.
In the accompanying drawings, in which my invention is fully illustrated.
Figure 1 is a top plan view of a lunch box embodying my invention and improvements, showing the cover thereof closed.
Figure 2 is an end view thereof, showing, in dotted lines, a thermos bottle supported therein.
Figure 3 is a sectional view of my improved box on the line 33 of Fig. 2, the thermos bottle being shown in side view; and
Figures 4, 5 and 6 are enlarged fragmentary sectional views on lines 44=, 55 and 66 of Fig. 1, respectively, the means for securing the cover in closed position being shown disengaged in Fig. 6.
Referring now to the drawings, A designates the body portion of the box and B the cover thereof, said cover fitting over the upper edge of the body of the box and its position thereon being defined by shoulders formed parallel with its lateral edges adapted to rest upon the upper edges of the lateral sides of the body portion of the box, in a usual manner.
Both the bod portion and the cover of the box are made 0 metal, usually tinplate.
The end walls of the body portion A of the box extend above the side walls thereof, as shown at 1, and are shaped to conform Serial No. 625,982.
substantially to the shape in cross-section of the cover of the box, being proportioned so as to fit within the same.
Formed on the projecting upper portions 1 of the end Walls of the body portion A of the box, are lugs or brackets 2- and' 3 adapted to form supports for a thermos bottle 4, shown as resting upon the same. Said brackets 2 and 3 can conveniently be formed by stamping them directly from the upper end portions of the body of the box, and theeover of the box is made of such shape in cross-section and is so proportioned that when secured to the body portion of the box, it will confine said thermos bottle in position on said supporting lugs 2 and 3. As shown, the upper portion of the cover B of the box in which the thermos bottle 4 is confined, is formed on the arc of a circle sub stantially concentric with and slightly larger than the thermos bottle supported onthe lu s or brackets 2 and 3.
ith the described construction, itis obvious that when the cover B of the box is adjusted to the body portion thereof, it'will securely hold the thermos bottle in position on the brackets 2 and 3.
here the thermos bottle is larger at one end than at the other, as is usually the case, the lug 2 on which the smaller end of the thermos bottle rests, is preferably formed at a sufficient distance above the lugs 3 which supports the larger end of the bottle, so that the sides of said bottle will be substantially parallel with the circular upper side of the box cover B.
In the preferable construction shown, the cover B of the box is adapted to be secured to the body portion A thereof by suitable catches adapted for engaging opposite ends of the cove-r with the upwardly extending projections 1 of the end walls of the body portion of the box. Said catches are duplicates of each other, and a description of one thereof will apply equally to both. Accordingly, the description of said catches is in the singular.
A preferable form of catch for securing the cover in position consists of a strip of sheet metal 5, slidably fitted to a bearing formed at the end of the box cover, which comprises downwardly and inwardly turned sections 6 and 7, the section 6 forming a connection between the section 7 and the main portion 5 of the catch. The section 7 forms the catch proper, and is adapted to engage holes 8 and 9 formed in the end wall of the cover and in the upwardly extending portions 1 of the end walls of the box, the relation being such that engagement and disengagement of the catch 7 with and from the holes 8 and 9 may be effected by endwise movement of the main supporting section 5 of said catch.
As shown, the slide bearing for the main supporting section 5 of the catch is formed by a struck-up portion 10 of a plate 11 secured to the box cover. When the plate 11 is secured to the box cover, the wall thereof will close the open side of the bearing in said plate and thus confine the slide section 5 ofthe catch therein, the relation being preferably such that the dimension of the slide bearing corresponding to the thickness of the slide, portion 5 of the catch will be sufiiciently greater than the thickness of the slide section of the catch to permit limited play of said slide section in said bearing. Said slide section is adapted to be secured in position corresponding to full engagement of the catch proper 7 with the holes 8 and 9 in the cover andbody portions of the box, by engagement of a shoulder 12 on the slide portion 5 of said catch with the inner end of the struck-up portion 10 of the bearing plate 11, such engagement of said shoulder 12 with the inner end of said bearing plate being effected by a spring 13 secured to the box cover. beneath the slide portion of the catch. As shown, the spring 13 is a leaf spring, its outer end being riveted to the box cover in such relation that the free end of said .spring will be substantially even with the end of the struck-up portion 10 of the plate 11, designed for engagement by the shoulder 12 on the supporting section 5 of the catch. WVith this construction, it is obvious that when the shoulder 12 is in engagement with the end of the bearing plate 11, the catch will be secured substantially in positive engagement with the holes 8 and '9 in the cover and body portion of the box,
Movement of the slideportion 5 of, the
catch in a direction to effect disengagement of the catch 7 from the holes in the cover andfthe body portion of the box, is limited by a stop consisting, as shown, of the turned up inner end 141 of said slide portion, said turned up end portions also providing convenient means for depressing said slide portions 5 of the catch against the force of the spring 13, to effect disengagement ofthe shoulder 12 on said slide portion 5 from the end of the struck-up portion 10 of the bearing plate 11 and for exerting pressure on said slide portion to effect disengagement of the catch 7 from the holes in the cover and body portion of the box.
In the preferable construction shown,
also, a T-head 15 is formed on the turned up section 14 of the slide section 5 of the catch to which an end of the handle 16 on the box, whichmay conveniently be made of leather, is attached, said handle being provided with slots 17 for attaching the ends thereof to the T-heads 15. 1
In the preferable construction shown, also, the bearing plate 11 is adapted to be secured to the cover of the box by means of iugs 18 formedby stamped down portions of said plate, which extend throughand are bent back over the remote'fedges ofholes 19 formed in the box cover B in proper position. The holes forined in the bearing plate 11 by stamping out the lugs 18 preferably register with the holes 19 stamped in the box cover, thus providing ventilation for the box.
I claim 1 V 1. A lunch box comprising a body portion and a cover therefor, said cover extending above the body portion of the box and being of sufiicient size to contain a thermos bottle, the end walls of the body' portion of the box comprising portions adapted to extend upwardly into the cover of the box, means for supporting a thermos bottle on the upward extensions of said end walls, andmeans for securing the cover to the body portion of the box, substantially as described;

In Witness that I claim the foregoing as my invention, I affix my signature this 27th day of February, A. D. 1923.
