English Abstract


ABSTRACT OF THE DISCLOSURE
The stackable container is folded from a blank and has
a bottom surrounded on all sides by an upwardly widening conical
wall. Triangular folding parts are provided in the corner regions
and meet at common tips at each corner. At the corners, the
folding parts are folded over one another so that, in each case,
three layers of material are superposed. In all there are seven
folding parts having folding edges which touch after being folded.

1~39688
The presentinvention relatesto astackable container which can be
foldc~ from a blan!c, compririn" a botto~ rurrounded on all ride. by
an u?~J.~dly ~ enin conical \~all, the container alro comprisin~
t-i~n~ular foldin part. havinL four co~r~on tips dir~po.ed at the
co-rer~ of the botto~ and at the connectin~ point bct~:een the botto~
and t~o wall co~.partMentO, the tip~ beinr folded over one another in
three layerO of r~aterial for.ing the tra..ition bet~een ~!all co~part-
~entr.
Containers of thi~ kind u~;ually have three trianular foldin~
partrt at each corner. ~o~Jever, three folding parts of the aforeMentioned
kind cannot of course en~ure high stability. At all e~ent6, the prior-
art containers of thi~, ~ind u6ually have a fold or s.imilar reinforcement
at the ed~e. ~or e~ample, in the de~cription of a kno~m container (Ger~.an
OS 18 10 600, US PS 35 36 248), the poriribility of doing ~ithout an
aforementioned folded edge ir. mentioned but the only embodiment r.ho~m
and deOcribed in detail har an aforementioned folded ed~e. Of cour~.e,
the folded ed~e increares the co~plexity of the conrtruction and
~nufacture of the container. In addition, the ~:no~m container har. to
be Omall (it ~urt be posOible to eat it from it directly). It i~ clear
that, aO a re~.ult of its con6truction~ itô dinenrionO cannot exceed a
certain ~mall value.
The object of the invention ir. to conrtruct a container of the
initially-~entioned kind w]lich io r7iMple in con6truction and, even if
made relatively la~e, ir r.ufficiently ~table to store liquidr and other
ca~ily-flo~in~ bu~s rubr.tancer..
To thi~ end, accordin~ to the invention, ~.even folding partr are
dir-por^d at each tip, and foldin~ ed~es on the ra~e side of the ~a~e
foldinD part are in contact ~ith one another after being foldcd.

n~mber of bent edgec. The ~reater ~tability of the eorner~ i~. of eource
very ;~portærlt for filled contairler~. r~ a re~ult of the bent ed~ec

i~ cistributed over the adjaeent side urfree~ if it Cr~rlnGt be borne
b~r the eGrner re~ion~ therr~elves. It has rlco rcer ~ho~m that the
cGrner regior ic also Made more recilient by ineYeac-in~ the number of
folds. Cf ecurce, the eorner reOion must be ~table, but it muct al~o
have corrle re~ilienee _o that it is not dr~r,a,re~ `uy a ~ all impaet.
Recilienee ic provided in that the folds at the corner open ~lightly
if subjeeted te a eorrespondinO foree.
The c-dge~ of the folding par~s are folded on one &nother at t~/o
plaeec on the inside and at one plaee on the out;ide. The folded ed~ec
oi folded-over re~ionc toueh. Accordingly~ onlywith greatdiffieultiesDIaterial~
if ~y, ean penetrate behind the fold at thi~ plaee. 'rhic accordingly
prevents the fold fro~ yieldinO or being other~ice damra~ed. It has
been found that the container according to the invention can be made
relatively laree, even if made of paper or eardboard. Sinee paper or
eardboard is permitted a~ a eontainer material for stoIing any ehemieals
in ea~e~ ~:here pla~tie~ or metal are l~lcuitable, the invention providec.
a container ~ahich is ~imple if prefer,ably made of paper or eardboard,
~hich ir, al~o suitable for ~torin~ corrooive che,icalr. The conta;ncr,
ho~:cver, ic Y y ftable and reliable, ~hich of cou~rc ir requircd ~rhen
~torin~r the afore?nentioned cher~icalf,. The cGntainer, ho~i ver,ha5 the
advantage that the fold can be rade in a relatively si?~le r~lner alon~
ctraiOht line~, co that the contail-ler can be foldcd r-!cc}~ ically.

hlthollgh prcfclab]y r,a~c of pa?cr o~ card:Joa~, the cGnt~iner can
of cour~e be rla~e of other rnateria~ uch a~ ~lactics or ric-ta].
If the container i~ rrade of cardboard~ the ~itability rnay a~ivan-
taceously be ~reatly increased if multi-layer cardboard io u~ed.
The container can be folded after the ~i~e in the r~ulti-layer cardboard
has hardened. If, however, it i~ folded before the ~,ize harden~,
no additional ~izinr i~ needed for r~aintaining à ~table fold after the
folding pre~ure or tool has been removed. It ha~ been found
particularly advantageou~ to make the container of five-layer cardboard.
A particularly ~uitable rDaterial is Scandinavian quality Kraftboard
or soda paper. The thic!-ne~r, of each layer of rnaterial should be about
300 g/m and 0.5 r~n, in order to have a container ~hich iz particularly
~uitable for the de~ired purpor;e. The layers can be ~i~ed with
polyvinyl alcohol ~,ize or di~per~ion or fu~ion ac7hesive; the~e r~aterial~
have been foun~ particularly ~uitable. -Of course1 other kinds of ~ize
r1ay alr/o be u~ed.
The advantage~ of the cont~iner according to the invention can be
fully u~.ed if the capacity i8 at leaOt 56 litrer,. A cap~city of 56
litrer rnaker, full use of the advantager, of the container according
to the invention and ir, al~o comatible ~ith the Otandard~ for
packa~in~. ~arer-capacity container~ ray al~o advantageou~ly be u~ed,
and of course container~ can also be r~anufactured for sr3aller capacities.
In order further to increase the ~,tability of the container and protect
its top ed~e, the edge can be provided l!ith a flanged r3etal strip
preferably about o.8 rrr, thic~. The r;letal ~trip of course also
prevents the fold re-opcnin~.
The container can have an in~ardly projecting bead or corrugation
parallel to and under the edge. ~hi~ fcat-lre further increa~e~
~tability. In addition, if the container ha~ a cover, the projection
can forr3 a bearin~ ~urface for the cover, ~:hich can tilen bc ~ccured on
the container and prevcnted from r~oving. A ~.eal can al~o be provided

The coverO in question are mainly made of l~ood~ board, metal,

be a ~econd, some~hat ~maller container ~hich fits into the top edGe
of the larger container and rests on the projectin corrugation. This
of cour~e ~ill greatly increa~,e the capacity of the container.
The contziner according to the inver.tion ha been founcl vcry
