FOLDING BOX Filed OCT.. 30. 1929 A TTORNEY.

Patented Nov. 24, 1931 vUNITED STATES PATENT OFFICE A Application med October 80, 1929. lcrlal lo. 403,585.

The invention relates to folding boxes and particularly to paper board boxes adapted to withstand rough handlin such as in the shipment of. goods by freig t or express. l`" The object of my mventlon is to rovide a pa r board folding box that is rea ily set up anewhich is provided with novel reinforcetmpnts to give a maximum strength to the x. The invention is illustrated in the accompanying drawings, in which Figure 1 is a plan view of the blank which, when set u forms the box Fig. 2 a plan view of the box 1n set-up-condition; Fig..3 a crosslu section on line 3-3 of Fig. 2; Fig. 4 a crosssection on line 4-4 of Fig. 2.

In the illustrative embodiment of the invention the blank 1 is formed'from a sheet of suitable paper board and is scored along the

broken lines

2, 3, 4 and 5 tovform the bottom section 6 and the

side sections

7, 8, 9 and 10, the scorin forming fold lines for the side sections. wo o posite side sections, as 9 ,i and 10, are exten ed and'scored at 11, 12 to L2 5, form two

flaps

13, 14 which are adapted to fold inwardly anddownwardly on the scorings 11, 12 when the

sections

9, 10 are erect.

Further extensions

15, 16 are formed on the

aps

13, 14 and defined by the

scorings

17, 18, 30 the outer edge of each extension preferably being serrated and adapted to engage the bottom section and the opposite edges of a reinforcing section 19 that is secured to the bottom section. This engagement of the

extensions

15, 16 with the bottom section and with the reinforcement 19 lock .the sidewalls in upright position. I find that by applying a minimum amount of glue to the bottom secl tion preferably in laterally'separated relatively narrow streaks and pressing the section 19 onto said streaks of glue that the said section 19, as thus attached to the bottom section, increases the lstrength of said bottom section much more than if the entire surface 4.5 of the section 19 were secured to said bottom.

The corner sections 20 are defined by the

y scorings

21, 22, the scorings 21 between the sections 20'and the

side sections

9 and 10 being such that the fold lines formed thereby are @5 weaker` than the scorings 22. Each corner section is diagonally scored at 23, a portion of each scoring consisting of perforations in the material. The weakened

scorings

21 and 23 cause the corner sections to collapse and fold against the

side sections

9 and 10 when 55 Ehe latter sections are elevated to set up the Each side section 9 10 is extended at opposite ends to form the flaps 24 which, when the box is set up, fold inwardly against the ad- 30

jacent side walls

7, 8 respectively. These ggps reinforce and stiifen the corners of theI Extensions 19 are formed on the reinforcing section 19 and abut the

side walls

7, 8, to 55 reinforce the latter walls alongtheir junction lines with the section 6.

The top or cover portion of the box is similar to the bottom portion except that it y is slightly larger than the bottom so that the two ortions will telescope. If the box is square t e top portion will be-so placed on the bottom portion that

itsA aps

13, 14 abut the

side walls

7, 8 of said bottom portion and thereby secure three thicknesses of material at each side of the box. When the box is rectangular in form the

flaps

13, 14, the

y locking extensions

15, 16 and the flaps 24 thereon are formed on two opposite side sections of the bottom portion, such as sections so 9, 10, and on the top portion said parts will be formed on the

end walls

7, 8 thereof, the reinforcing flaps 19. bein ada ted to abut the remaining opposite si e wal s of the top portion, whereby to secure three thicknesses of material on al1 sides of the box when closed.

It is thus seen that I have provided an exceptionally strong and rigid paper board box that will withstand a maximum of abuse in 9o handling.` When collapsed the two box portions occupy a minimum of space and it requires very little eifort to set them up when required for use.

What I claim is:

1. A flat, unfolded blank for folding boxes including a body portion, wall-forming portions at the sides ofthe body portion and defined by weakened fold lines, collapsible corner members defined from adjacent wallfined therefrom by weaken extending from the opposite free end edges of f the body portion when folde the free lonn gitudinal ed of each latter fla being sery 19 rated, a rein orcing member on t e body portion adapted to be enga ed at two opposite y edges by said serrated edges and Hap exten,- sons exten from the remaining opposite i edges of the reinforcing member and adapted 15 to ngge the adjacent wall-forming portion an t fold line thereof; l 2. A flat, unfolded blank for folding boxes gaing the remainin opprsite side walls, an 'extensions exten mg m the opposite ends of the flap extensions on two o posite side wells and folded inwardly to reinforce the remaining side walls and the fold lines thereof.

In' witness whereof I have hereunto signed my name.
