This invention relates to foldable paper boxes and has particular reference to that type known as berryboxes, etc. 7

The object of the present invention is to generally improve and simplify the construction and operation of boxes of this character; to provide a blank which may be cut from stock such as cardboard or the like with a minimum of waste; to provide a blank which lends. itself to printing operations readily and which when folded to form a box, presents a smooth exterior surface for display ing the printed matter; to provide a blank and box which may be compactly. piled for shipment either in the blank or folded box o form; to provide a box of the folded blank type whereby a single integral blank is scored a of Figure 1,

particularly Figure and cut by a die or the like and then folded and glued to form sides, legs and a bottom section; to provide a blank which is so cut and scored {that substantial double ply reenforced corners are formed during the cutting operation and further to provide a' blank which is adapted to be folded and glued by machine operation. The invention is shown by way of illustration in the accompanying drawings in which: a

Referring to the rawings,jin de ail, and

The blank is substantially sqiiare in'shape and may be cut with standard dies or'the like irom paper glued and assembled by Figure 5. Glue is applie'don stock, such as cardboard, etc. During the same operation, the bottom formed by scoring the blank along the dotted l1nes indicated at 10. These scorg lines also form the lower edges of the side sections 2-, 3,

portion A is 4 and 5. The cornermembers 6,7, 8-and 9 are out along the lines indicated at 11-'-11-, 12-12, Iii-13: and l t-"14. The cut' se'ctions 121 2 are-substantially parallel and at right angles to the cut section-11 and forms the legs generally indicated'at 15:" The cut sections 13 are on a flare or-angle with rela-- tion to thecut sections 12 and thecut sec-- tions 14 are substantially-at: right angles to the cut-sections 12 so as to form-overlapping; flaps '16 whereby the corners of the box are reenforced and secured.

' The corner members arefcentrally'scored alonglthescore lines indicatedat 17 and scores are also formed atzthe points indicated at 18-48 and 19-+-19.- Tie strips-20am thus formed between thecornefr sections and 4 the side sections which retains the corner; members in positionwhile the paper stock is in a blank state andcalso during the folding";

Further ventil'ation ma be obtained. by slotting the sides of the box ut as this is common, illustration thereof has been eliminated.

. When asquare box such as. shown in Fig- 1 ure 1 is being. made, the blankprovided will fl'be substantially square in outline. If a line willbesu stantially hexagonal, that is,- theinvention isby 'no means limited :to a square slhapedbox, as it is obvious from the drawings submitted that hexagonal-shaped boxes and the-like may be obtained by slighthexagonal-s'ha ed box is employed,.the out- ;ily changing the shape of the blank; in any instance, it' willlbe noted that the blank maybecut from stock withaminimum of waste I and that comparatively simple dies may-.be

employed as. stripping and punching operations are entirely eliminatedwhen forming blanks such as here illustrated. Economy of material is thus obtained, die costs and bottom o maintenance is also reduced." .The-box obtained is materiall Y r'eenforced'by the corner members. and'lis rther reenforc'ed by the glueinte osed between the surface of-the ends of t e side sections and. the exterior surfaces'of the-corner'fsec'ti-ons'. The supporting legs projecting below the material and stock and'without waste and ventilatin openings are formed in'the bot.-

tOmwhic srkmitting the legs to protrude. A box of this also-s'erve the function of percharacter lends itself readily to machine op' erat-ions' thereby further reducing. costs and pact 'assem led condition. ,All surfaces formed the box also lends itself to nesting and comiling'both 'inthe blank and .in the are smooth and unobstructed and as such ma be printed and the printed matter may be displayed to advantage. While certain featuresof the-present invention aremore or less specifically described,

I wis h it understood thatvariousv changes may be resorted to within the scope of the appended-claims. Simila'rlythat the matemils and finishes-fofthe-several parts employed may besuch as the manufacturer inayg-decide or varying conditions or uses may demand.
