4 Claims. (o1. zzo-ri)
The present invention relates to paper board
cartons and has for its object an improvement
in pouring cartons in which a pouring aperture
may be made in the/carton for permitting dry
be
5 pulverulent or granular contents thereof, to
emptied from the carton.
In the present embodiment, the carton ymay
be made up of a single sheet of paper board and
may comprise the usual body forming panels set
up to form a rectangular carton with flaps ex
tending from each end of each panel to form top
and bottom closure flaps.
One of the features of advantage of one of the
closures shown herein is that after opening the
' same, it may be tucked into its original posi
tion to be held as a reopenable and reclosable
pouring tuck flap.
Other advantages will be noted as the herein
disclosure proceeds and it will be obvious that
modifications may be made in the structure here
in without departing from the spirit hereof
the scope of the appended claims.

embodiment of the present device, closed;

The present pouring closure is developed about
one of the corners of the carton, and as shown in
the drawing, the carton may be of the standard
form previously noted.
The cooperating parts of the closure involve at
least two adjacent angular walls of the carton
which forms a corner thereof and at least two of
the coacting closure flaps, when in carton as
sembly.
In Figs. 1 and 5, the adjacent side panels I, 2
and 3 have extending closure flaps 4, 5 and 6 re50 respectively. Closure flap 5 is scored from its
narrow panel 2 by a common score line l, which
also scores flaps 4 and 6 from panels I and 3, aS
in Fig. 5. As shown in Fig. 5, flaps 4, 5 and 6 are
55 defined from one another by cuts 2li-_20, which
extend from the outer edges of said flaps- down
to the score line 1, and thus the said flaps are as
customary, each being independently foldable
upon one another, after gluing.
‘
Flap 4, Fig. 5 has its edge, adjacent the cut 2li
and flap 5, provided with a senil-circular cut-out
I2. Likewise the flap 6, adjacent its cut 20 and
the flap 5, has its edge provided with a senil
circular cut-out I3.
It will be seen that the
flap 5 and its appurtenant panel 2, Fig. 5, is pro
vided with a circular pick-out piece I0 defined
half and half out of each portions 2 and 5, by
a circular line of perforations, such circular pick
out piece spanning the score line 1, so that when
>the carton is formed and closed in rectangular as
sembly as in Fig. 1, with all flaps 4, 5, 6 and the
opposite _mate ñap to 5, not shown, are glued
to one another the pick-out piece I0 is formed
on the corner junction of flap 5 and panel 2.
[The flap 5 and its companion flap, not shown
are' first closed down, and then flaps 4 and 5 are
glued on their underfaces and closed down, with
the circular cut-outs I2 and I3 bordering that
half section of the piece I0 which is in flap 5.
Thus cut-outs I2 and I3 provide a finger space 25
about the half section of the cut-out piece I0.
To open this particular form of package the
user grasps the angularly disposed pick-out piece
I0 between a finger and thumb, and pinches it»,
thus causing the pick-out piece to break at its
line of weakening I I, the removed section I0 then
being discarded, leaving the package with the
opening T, as in Fig. 2, ready for pouring out
the contents.
In the alternate form shown in Figs. 3, 4 and
6, in which like portions of the carton bear like
indices for parts similar to those of Figs. 1, 2
and 4, the flap 5 and the Vpanel 2, Fig. 6, have a
pick-out tuck flap I4, partially defined thereon
by a cut-through semi-circular line I5 on flap 40
5, the ends of said semi-circular cut ending short
of the score line 1, and being there joined by two
perforated weakened lines I5-I5, which ex
tend past the score line l, and down a suitable
distance onto panel 2, Where they endv at a trav
ersing score line S.
That portion of the tuck flap I4 located on the
panel 5 and about the margins thereof is coated
with a glue resist I1, such as wax or ink, so that
when the ilapS 4, 5, and 5 are in glued assembly 50
the end of the tuck flap I4 and its margin as
overlaid by glued flap 4, is free from glued at
tachment to ilap 4. As the finger opening cut
outs I8 and I9 on closing flaps 4 and 6 are smaller
in dimension than the rounded end of tuck flap

IB-Il, the'semi-circular cut-through Il is cov
ered bythe flap I, which thus prevents sifting

» 7. under flap I, Thus this latter flap not only
renders the contents of the package accessible, but
it also performs the function of reclosable tuck
nap, to close the pouring aperture and protect the
remaining contents of the carton.
'I‘hus it will be noted that the present pour
ing means are created in a fiat one piece blank,
without added parts and wholly within the con
fines of the blank itself.
Having thus described the invention what is
claimed is:
1. A carton comprising a front wall having
thereon a flap forming an under end closure
member, said wall .and member having therein
a tear out tuck to provide a pouring opening;
said tuck having a base part in the walland
a free terminal and marginal part in said mem
ber, there being weakened lines on opposite sides
of said parts and there being a cut extending
from the ends of the lines around the terminal;
and two side walls having thereon flaps forming
upper members of the closure, said upper mem
bers having therein finger spaces which register
above said marginal part, the contour of the
space boundaries'being such as to cover the said
lines in the marginal part, said cut being then
covered in sift proof relation by the flaps thereat.
2. A carton comprising a front wall having
thereon a flap forming an inner under end clo
sure member, said wall and inner member hav
ing therein a tear-out tuckable ñap to provide
a pouring aperture; said tuckable flap having a
hinged base part in said wall and a free terminal
in) and marginal part positioned in said inner mem
ber, there being spaced lines of Weakness deñn
ing said hinged base part from said wall, there
which, when in closed position forms la corner
with said wall, a tear out portion on said corner
deilned by lines of weakness on said wall and
flap, the part of the tear out portion on said
flap being coated on its face and beyond the
margins of its line of weakness with a glue re
sist, and upper side closing flaps on said carton '
which are superposed upon the under closure flap
and glued thereto, said closing flaps being pro
vided with finger spaces which are superposed
over the coated face of the tear out portion,
the edges of the linger spaces extending over
the line of weakness of the coated face of the 25
tear out portion in a sift preventing manner, as
and for the purpose described.
4. The combination in a carton, having a front
wall, of an under closure flap on said front wall,
which, when in closed position forms a. corner
with said wall, a tear out portion on said corner
for forming a closable corner pouring aperture
when broken and defined by lines of Weakness
on said wall and flap, the part of the tear out
portion on said flap being coated on its face 35
and beyond the margins of its line of weakness
with a glue resist, whereby to maintain said tear
out .portion on said ñap portion detachably free
of glue and upper side closing flaps on said carton
which are superposed upon the under closure
ilap and glued thereto, said closing flaps being
provided with finger spaces which are superposed
over the coated face of the tear out portion,
whereby to afford manual access to the `tear out
ñap portion, the edges of the finger spaces ex
tending over the line of weakness of the coated .
face of the tear out portion in a sift preventing
manner and forming a superposed retuck seat
for the flap tear out portion whereby the flap
tear out portion when reclosed, will occupy its
original aperture and seat in said closure flap,
