SHIPPING CONTAINER Original Filed Sept. 21, 1929 Patented Nov. 24, 19731 UNITED STATES PATENT OFFICE CLARENCE I. GATES, JR., or CHICAGO, ILLINOIS, AssIGNoR rro CHICAGO FIBRE Box COMPANY, or CHICAGO, ILLINOIS, A CORPORATION or ILLINOIS SHIPPING CONTAINER Application led September 21, 1929, Serial No. 394,217. Renewed August 17, 1931.

The present invention relates to shipping containers and more particularly to that variety of shipping container adapted to be collapsed for shipment and storage, one object of the invention being to provide ay simple, economical and exceedingly strong construction of container which can be shipped to the i user in a. flat or collapsed Condition and which can be quickly and easilytset up and sealed without the use of any expensive equipment, such quiring the additional labor which such equipment usually necessitates.

The so-called slotte'dcarton has several outstanding disadvantages fromthe standpoint of economy and strengthfor the reason that double walls are provided in this type of container at points Where they are unnecessary, thus wasting considerable material; and at points where double Walls would be desirable and necessary this type of container'fails to providesuch reinforcement. Among the advantages of the slotted carton are the com- Each body blank 5 comprises a Side Wan 7 pactness with which it can be bundled uwhen collapsed and the ease with which it-'can beset up, packed and sealed for shipment since no complicated and expensive machinery'is required in these processes. Y

A further object of the invention is lto provide a vuniformly reinforcing container having all of the advantages ofthe so-called slot-v ted carton in that it will be collapsible and easy to set up and seal, and also will have the further advantages of being able to safely carry a Weight per unit of volume substantially twice the weight now permitted by the freight classification committees to be carried in slotted cartons. Y

fA still further object is to provide a container'which readily adapts itself for use with reinforcing bands and in which no further sealing means other than reinforcing bands are required. i y

Tofthese and other ends the invention resides in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

as a stapling machine, and without rey Referring more particularly to the drawv ings:

Fig. l is a perspective View of the container of the present invention as it appears when set up ready for packing;

Fig. 2 is a perspective view of the container as it appears after being packed and sealed ready for shipment; and

Fig. 3 is a view of the container in a col lapsed condition.

Similar reference numerals throughout the several views indicate the same parts.

The invention, as herein disclosed, comprises a container made up of four blanks which are formed so as to reduce the waste to a minimum and in which the blanks are secured together in such a way as to provide reinforced corners and also are secured in such a manner as to adapt the container to be collapsed fiat for convenient shipment.

Referring more in detail to the drawings the container is illustrated as comprising two body blanks-5, 5 and two end blanks 6, 6.

y tom closures for the container. In the present instance the cooperating closure flaps 8, 8 are disclosed as somewhat overlapping but obviously they may be of such length as to just meet at the center of the container or they may be made sufliciently long to more completely overlap yeach other.

The end blanks 6, G are preferably identical as in the case of the body blanks 5, 5. Each end 'blank is preferably formed with a substantial iiap at each side thereof, two of the flaps being indicated at 9, 9 and the remaining two being indicated at l0, l0.

The flaps 9, 9 are preferably secured to the inside surface of the side Walls 7, 7 by suitable means such as staples ll (see Figs. l and 3). Aifter the blanks have beenvsecured together at the box factory in this manner it will be evident that the container is in readiness to be collapsed as clearly shown in Fig. 3. In this condition the closure liaps are all extendedk so as to lie substantially in the plane of their adjoined walls and the thickness of the collapsed container Will at no point be greater than substantially three thicknesses of the material from Which it is made. After the container reaches the user it is a simple matter to set it up ready for packing-...1 The flapsv9, in overlapping the side Walls and being-secured thereto,..provide a much stiller vertical corner for the container to thus prevent injury to the contents of lo placed uponitand also tendl tofprevent'colllapse of the corners inwardly in cas.e.,.of.a7 heavy object falling against the corners du'ring shipment-f.
