LUNCH BOX Filed Aug. 23, 1948 Jacob W. Coney INVENTOR.

BY WMIEEZ-MH Patented Sept. 23, V 1952 The present invention relates to new and useful improvements in lunch boxes of a novel construcion.

An important object of the invention is to provide a lunch box of plastic or similar transparent material whereby the contents of the box may be inspected without necessitating opening of the box.

A still further object of the invention is to provide a lunch box composed of a pair. of separable side sections together with means for securing the sections together in a closed position at their top and bottom portions and without requiring the use of metal fasteners.

A still further object is to provide a lunch box of simple and practical construction, which is neat and attractive in appearance, strong and durable, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts through-out, and in which:

Figure l is a perspective view;

Figure 2 is a longitudinal sectional view taken on the line 22 of Figure 3;

Figure 3 is a transverse sectional view taken on a line 3--3 of Figure 2 and Figure 4 is a fragmentary plan view of the interior of the bottom looking in the direction of the section lines 4-4 of Figure 3 and showing one of the fastening means therefor.

Referring now to the drawing in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention the numeral 5 designates a substantially rectangular shaped bottom portion of the lunch box and the numeral 6 designates the substantially cylindrical shaped upper portion thereof all of plastic material. The lunch box is formed of a pair of separable side sections 1 and 8, each side portion including substantially one half of the rectangular shaped bottom portion 5 and the side portions of the cylindrical upper portion 6 being separated along a, longitudinal line offset from its lon tudinal center line to separate the upper portion 6 into relatively large and small areas 9 and III.

A pair of apertured lugs H are suitably secured to the upper surface of the large portion 9 in which square shaped split loops [2 are secured. The upper ends of the links are loosely engaged in longitudinal slots I 3 formed between upper Application August 23, 1Q

and lower handle plates M and I5 secured in spaced relation one above the other by spacing blocks IE to permit vertical swinging movement of the handle upon the lugs ll.

The lugs H, loops I2 and handle plates l4 and I5 with the spacing blocks l6 are also constructed of plastic and the loops l2 are of sufficiently resilient material to enable removal by spreading apart the split ends thereof to remove the same from slots [3. The loops may also be removed from the lugs l I by turning the same to bring its split end lowermost for removal from the opening in the lugs. Openings I! are formed in the top section 9 to facilitate this turning movement of the loops.

The meeting edges of the bottom l8 and I9 of the side sections land 8 are secured to each other by means of tongues 20 projecting from the edge of bottom l9 into an opening 2| in the adjacent edge of bottom l8 under a locking bar 22 and over a locking bar 23 suitably secured in bridging relation respectively above and below the opening 2 I. The free edge of tongue 20 is formed at its undersid with a locking lug 24 engaging the bar 23.

The meeting edges of the sections 9 and I0 are similarly secured to each other by a locking tongue 25 suitably secured to the upper surface of section 9 and received in an opening 26 in the adjacent edge of section In and looked over and under spaced parallel bars 21 and 28 bridging the opening.

The upper outer edge of tongue 25 is formed with a locking lug 29 engaged behind bar 28.

Each side section I and 8 is provided with an internal support 30 and 3| suitably secured to the sections at the junction of the bottom and top sections 5 and 6 and a-lined with each other to support a Thermos bottle in the upper chamber 9. In the use of the invention, the side sections 1 and 8 may be swung open at their upper edges by releasing tongue 25 and partially releasing tongue 20 and food may then be placed in bottom section 5 and a Thermos bottle placed in up per portion 6. V

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though ti-ble to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.

Having described the invention, what is claimed as new is:

A lunch box comprising a pair or separable side sections forming a substantially rectangular shaped bottom chamber and a substantially cylindrical shaped horizontal top chamber positioned longitudinally one above the other,-means locking the upper meeting edges of the top chamber to each other, and means locking the lower meeting edges of the bottom chamber to each other, said locking means including tongues projecting outwardly beyond one meeting edge and received bridging the openings, and lugs on ,thelbongues 4 7 REFERENCES CITED The following references are of record in the file of this patent:
