Claims. (Cl. 229-31) This invention relates to the art of dishes and CM, and DN and DO. The upper surface of the particularly to a dish formed into shape from a blank is coated with some water proofing material such as paper, fiber board, and the like, material such as paraffin over the entire surface where the dish is first cut out in blank form and thereof with the exception of those surfaces be- 5 then folded to bring it to the desired shape. yond the dash lines in each of the triangles A primary advantage of my invention is that formed by the same lines and the outer edges the dish is formed by a bellows fold at each corner AEF, BIJ, EKL, and DOP, these dash lines being whereby leakage is prevented. A further imporcontinuations of the lines across the inner ends tant advantage of the invention is that there are of the notches cut out of the adjacent triangular 10 no inside exposed folds under which liquids may sections formed by the score lines. The under- 65 flow and the entire inner or upper surface of the side of the blank 10 is given a coating of an adfinished dish prevents continuous smooth surhesive over the surface only immediately below faces. A still further important advantage of the score line AG and the line AR as indicated my invention is that the upper surface may be by dash lines, a score line BH and the line BS waxed or paraffined without interfering with the indicated by dash lines, a score line CM and forming of tight corners and without the necesover to a line CT indicated by dash lines, and the sity of using staples. score line DN back to a line DU indicated by dash Further advantages are that the device may be lines. produced very rapidly at a low cost and at the The blank is then ready to be formed into shape same time provide a more serviceable, durable, by folding it on the various score lines to bring 75 and more sightly product.

Furthermore by providing the Each outer'corner of the blank is cut off dinotches as above indicated in certain portions of agonally and further out back with a notch bethe bellows folds, the adhesive unites not only the 5 tween the lines AF and FG, BH and BI, CL and adjacent portions of the folds with the respective 11'0 sides of the dish but also catches the outer portions of the folds adjacent those portions directly in contact with the dish sides by reason of such outer portions having the short lengths overlapping the then underlying portions to come into contact through the adhesive with the dish sides. Not only is this fact true, but a much neater appearance is obtained since the top ends of the folds present but a single thickness along the edges of the sides since the underlying portion is covered over. 7

In the foregoing description, the invention has been described as having the bellows folds turned around on the dish or container sides. It is obvious, as illustrated in Fig. 7, that these folds may just as well be turned around against, the ends, the notches, however, in this case, arecut from the upper ends of the fold sections EFA, IJB, CLK, and PDO instead of from the adjacent sections as above indicated. It is to be noted that the notches in either case are cut from those fold sections adjoining the side or end to be folded against. Therefore, the terms end and side of the dish or container are merely relative and interchangeable and are not used in a limiting sense in the claims hereinafter set out, since from one viewpoint a side may be an end, and from another viewpoint, an end may be a side.

Referring to Figs. 8, 9 and 10, a container is indicatedwherein there is a double bellows fold at each corner, which construction affords greater contacting area for the adhesive which secures the folds against the sides and ends. This type of corner is particularly advantageous in deep containers such as may be employed to hold berries and the like.

In Fig. 8. is shown a blank cut and scored preparatory to being folded to the shape indicated in Fig. 9. In this blank the. base ofthe container remains the same as in the first described form being bounded by the lines AB, BC, CD, and DA. The chief distinction between. this form and the first described form is found in the cuttingand scoring of the corner portions. In this modified form the lines AE and DP form score lines defining oneend, while the lines BJ and CK define score lines bounding the sides of the other end. Similarly the lines. AG and BH are formed as score lines to define one side, while the lines DN and CM as score lines define the other. side. Between each set of these score lines thus defined meeting at the junction of the lower. adjacent corners of a side and an end of the ,container, are the three score lines AV, AW, and AX. The triangular sections thus defined by these score lines are brought oneagainst the other as indicated in Fig, 9 as the sides and ends of the container are bent upwardly from the base 11. Notches are cut down from the top inthose sections immediately adjacent the container end and the container side respectively so that the upper ends of the triangular sections AVW and. AWX have ends projecting upwardly beyond those adjacent sections as indicated by those portions above the dash lines, whichprojecting endsare the ones that are not waxed over so that they may be brought up against the respective end and side of the container to be adhesively united thereto. The edges of the sides and ends of the container, are thus brought together in abutment with the triangular sectionAXG folded around against the side, the triangular section AWX around on top of. the section AXG, the, section AEV around against the containerend and the section AVW around on top of the section AEV,

to have the line AW come up to coincide with the line between the abutting end and container. The other corners of the container are formed in the same manner, the finished container hav ing the appearance as shown in Fig. 10 when viewed from the top.

While I have herein shown and described my invention in the one form as now best known to me, it is obvious that structural variations may be had without departing from the spirit of the invention and I therefore do not desire to be limited to that precise form beyond the limitations asmay be imposed by the following claims.

I claim:

1. A container formed by folding from a blank comprising a bottom, upturned sides and ends, and integral bellows-folds interconnecting said sides and ends, all of said folds extending around from said ends to lap over on the outer sides of said sides and being secured thereto by an adhesive between portions of said folds and said sides. said. folds each comprising two triangular portions of said blank having their apices meeting. at a common point. which is a corner of the bottom of the dish, said portions being defined by score lines radiating from said point, the one of said portions adjacent the dish side in each fold being shorter than the other portion therein, whereby. the said other portion overlaps the under portion and is adhesively engaged directly with the dish side.

2. A container comprising a bottom, sides and ends, integral bellows folds interconnecting the sides and ends, said folds each comprising a. pair of triangular-1y spaced. portions having their apices meeting .at a point coinciding with the intersection of a side and an end with the. bottom of the dish, each of said portions being united. along a fold line with a respective dish side and end and uniting along a common intervening fold line, said portions being brought into juxtaposition by hinging on the fold lines at the dishside and end and further turned around against the dish side to have said intervening fold line carried back from the dish end along the dish side, the port-ion juxtaposed with the dish side having a cut-away to expose the dish side therethrough, and the other of saidportions being, in contact with the dish side through said cut-away, and means securing said other portion through said cut-awayto vsaid dish side.

3. For a container, a blank of foldable material octagonally shaped and having score lines defining a. centralbottom with contiguous sides and ends .forthe dish, and intervening diagonal fold lines between the sides and ends, and having certain areas of the material between adjacent fold lines cut-away and having other areas adhesively united with each other through said cut-away areas, said blank being coated to have a waterproof surface to leave uncoated areas to permit adhesive action between adjacent fold lines on those parts of the material adjacent said cut-away areas. v w 4. A container comprising a bottom, upturned sides, and integral bellows folds interconnecting the sides having the portions, between the folds lapped one over, the other against the sides, the upper ends of the inner underlapping portions being removed to have theupper ends of the outer portions in direct contact with the sides to which said contacting portions are adhesively united through the removed portions.

5. A container comprising a bottom, upturned sides, and integral bellows folds interconnecting er portions in direct contact with the sides and adhesively united therewith through the removed portions, said folds being arranged to have a pair of portions between folds lapped around a on one side and a pair of portions between other folds lapped around on the adjacent side.
