VThis invention relates 'to- cartons, and more
stance is integral with the wall 8 and extends at
particularly to cartons formed of paper or
its relatively opposite ends beyond the corre- ,
analogous material; and an object of the inven
tion is to provide a _carton particularly designed
spending ends of the wall 8.
_Further the blank 6 is slit on lines' I3 which
form extensions of the fold line l, and is also 51
folded on fold lines I4 to provide for the walls.

I8, I 1, and I8 respectively.
Also at the lower edge thereof the blank 6 is

Briefly the invention consists in theprovision
'of a carton formed from ia single blank of paper,
suitably waxed or otherwise treated if desired to
render it impervious to liquid, and cut, shaped,
10 dimensioned and folded to provide a substantially
slit on lines I9 which slits I9 are in line with thc
elongated rectangular carton or receptacle hav

The invention together with its' objects and
advantages will be best- understod from a study
of the following description4 taken in connection
with the accompanying drawings wherein;
for the walls 8, 9, IU, and I I, bottom flaps 2|.
In act-ual practice the blank 6 is first folded

bodying the features of _the present invention.
thereof the blank 6 is foldable- on lines 20 to form
on the fold lines 1 and la with the extension I2,
as shown in Figure 6 disposed against the inner
face of the wall ‘I to align a window slot 22 pro
f vided in theflap'or extension 'I2 with a window

outwardly as at 24 so as to accommodate ,between N) 0

Referring to the drawings by reference nu
merals it will be seen, that in each form of the
invention a suitable blank is provided and this
blank is cut, shaped and dimensioned so that
when folded on predetermined fold lines a sub- „
>45 stantially rectangular carton is provided.

a reinforced, multi-ply bottom vwall 26 for the
' Also in completing the carton the flaps I5, I6,
Il, and I8 are folded over one another in super
imposed relation and adhesively united or other
wise secured together to provide a reinforced ‘
multi-~ply top 2l for the carton.
Further in accordance with the present inven
tion the innermost flap I8 is provided with an
opening 29 properly positioned, and which may
be of suitableedge contour, preferably being of
the edge contour shown. The flap I6 which is
disposed immediately in super-imposed contact
on the ñap I8 is also provided with an opening
28 of an edge contour corresponding to the open
-ing 29 but materially larger than the opening 29
so that the portion of the flap |8 immediately 45
defining the’edge of the opening 29 may serve,
Referring more particularly to the form of the
invention shown in Figures 1 to 7, inclusive, it
will be seen that the carton illustrated in these ' as clearly shown in Figures 2 and 3 as a ledge 30.
Also the ilap Il which is disposed in superim
figures and indicated generally by the reference
posed relation to the ilap I6 has struck out there-A
50 numeral 5 is composed of a substantially rec
tangular blank 8 ‘folded on parallel fold lines '| from a closure flap 3| that is of an edge con
to provide walls l8, 9, I0, and || respectively. tour corresponding to the edge contours of open
Further at one edge> thereof the blank _6 is pro
ings 28 and 29. By'strlking out the closure ilap 3|
vided with an elongated relatively narrow lateral from the top wall flap I1 there is provided in the
55 ñsmge or extension I2, which in the present in
flap Il an opening 32 that is substantially of the
saine size as the opening 28 as will be clear
from a study of Figures 2 and 3.
Also in accordance with the present invention
the top wall flap I5 which is super-imposed im
mediately upon the ñap I1 has a portion thereof
removed so as to provide an opening 33 that is
slightly smaller than the openings 28 and 32 so
that the edge of the ñap I5 defining the opening 33
pz'ojects- inwardly from the edges of the flaps I6
and |1 as shown in Figure 2 so as to form with
the ledge 30 an internal groove 34 that receives
the free edges of the closure flap 3i in a manner

cular and are of the same size te align 4with one
another when the flaps are in the super-imposed
position shown in Figure l0. Also the innermost
top wall ñap |811. is provided with a circular open
ing 39 that is slightly smaller than the openings 38
so that the flap |8a about the opening 39 forms
a ledge ¿lll upon which is adapted to seat a_ cir
cular or disc-like stopper 4| as shown in Figure 10.
Also, thez?lap |5a which is the outer or top 10
most top wall ñap is provided wit‘n a-suitably posi
tioned substantially circular opening 42, and at
the marginal edge portion of this‘opening the flap
|5a is pressed upwardly to provide a hollow cir

a pouring opening for which a closure flap formed
by the flaps 3| vand 3,5 is provided.
When the closure ñap is in completely closed
position ñap element 3| will rest on the ledge 3G

upper end of, for example the extension I2a, will

to exert a yielding pressure against the innermost
one of the top wall ñaps. to prevent a collapsing of
the top wall.
