7 Claims.
This invention relates to new and useful im
provements in containers, and moreparticularly
to ?exible walled containers such as paper bags,
adapted to contain a ?nely ground or pulverized
5 material as, for example, ?our, and various other
articles.

way, constitute a structural part of the bag body.

particular manner in which theouter "Cello

Since the advent of “Cellophane”, a great
many food articles are now wrapped or packed
with this material, primarily, because it greatly
1o enhances the appearance of the package, and,
furthermore, because it is very inexpensive.
There is one objection, however, to the use of
“Cellophane” for certain purposes, and that is, it
has a tendency to become more or less brittle

by loses its usefulness, particularly when the
“Cellophane” itself provides the walls of the con
tainer. The inherent nature of the material is

30 bag, whereby it provides only an outer enclosing
member therefor, and does not become a struc-.
tural part of the bag itself. By thus enclosing
the package in “Cellophane" greatly improves its
appearance, andalso renders it less subject to at
35 tracting dust and other foreign matter, when
handled. The “Cellophane” enclosing member is
desirably applied to the tube from which the bag
body is formed before the bottom of the bag
is constructed, and the bag bottom is then formed ‘
40 in the usual manner, after which the bag is
completed to receive the material to be packed
therein.

In the selected embodiment ,of the invention
here shown, ‘there is illustrated in Figure 1, for
purposes of disclosure, a bag generally indicated
by the numeral 2, shown having its lower end
slitted as at 3 in the usual manner to permit
10 folding the lower wall portions thereof, as shown
in Figure 2, to construct‘the bottom I of the bag.
An important feature of the present invention
resides in the unique construction of the bag
body which, as shown in the drawing, is provided
.15 with an outer enclosing member, generally in
dicated by the numeral 5.
This covering mem
ber is of a suitable material such as “Cello
phane,” which preferably is transparent so that
the printed matter, indicated by the numeral 6,
20 which usually is applied directly to the walls of
the bag body, may be clearly seen through the
outer enclosing member.
The lower edge ‘I of the outer enclosing meme
ber 5 is provided at its upper end adjacent to the
rear wall 20'with an upstanding portion 23, pref
erably triangular in’ shape, whereby its shape
will conform substantially to the pointed ter
minal ll! of the flap ll of the rear wall. The
triangular portion 23 conceals the tip‘ IQ of the
flap I‘! when the bag top is completely closed,
whereby none of the wall surfaces of the bag top
walls are exposed, as is shown at A in Figure 5.
The front side of the “Cellophane” enclosing 10
member 5 may also be provided with a depend
ing portion 24, as best illustrated in Figure 7,
the width of which is substantially equal to the
spacing between the slits 3—3 in the lower por
tion of the blank or tube 2. In Figures 7 and 8, 15
it will ‘also be noted that the lower marginal
edge 25. of the enclosing member 5 is spaced
relatively closer to the lower edge 8 of the tube.
2 than it is ‘in the forms shown in the previous
?gures.‘ By constructing the lower portion of
the enclosing member 5 as shown in Figure 7,
when the bottom of the bag is formed, the lower
edges of the enclosing member 5 will be com
pletely concealed, as best shown in Figure 9,
wherein ‘it will be noted that the paper or mate 25
rial of the bag proper, which constitutes the bottom 4 of the bag, will be completely concealed by

‘A notch l3, preferably V-shaped, may be pro
vided in the upper edge I I of the enclosing mem
50 ber 5.
This notch will appear as shown’ in Fig
ure 4, when thebag top walls are partially folded
into closing relation. In Figure 4, it will be
noted that the end walls II and i5 of the bag
top have been folded inwardly, one over the
whereby ?aps l6 and I‘! are formed in the
55 ‘other,
upper portions of the front and‘ rear walls I0
and 20, respectively. Because of the V-shaped
ferred to the outer enclosing member as being
constructed of “Cellophane." It is to be under
stood, however, that any other material of a
similar character may be employed without de 45
parting from the scope of the invention. The im
portant feature of the invention, as previously
stated, resides in ?tting a “,Cellophane" enclosing
member over the bag body before forming the
bottom thereof, ‘whereby when the bag is ?lled
and the top thereof is closed and sealed, the bag
body will be enclosed in “Cellophane” without
necessitating any additional packaging opera
tions, as when the “Cellophane” is applied to the
‘bag body after the bag .has been ?lled and sealed. ' 55
Also, by applying the “Cellophane" to the bag
notch -.l3 provided in the upper edge of the en
blank or tube, as herein set forth, the sealed bag
may be enclosed in a “Cellophane” wrapper with
closing member 5, the terminal of ‘the flap i6 is
out materially increasing the packaging cost.
- The outer enclosing member 5 is preferably se
exposed, as shown at l8 in Figure 4, which per

ure 4, which secures the ?ap I‘! to the previously manner._ In other words, the “Cellophane" will
- not be secured to the entire outer surface of the
folded bag top walls, as shown in Figure 5.
The upper edge portion of the outer enclosing bag body, as it would be in a bag constructed of
member 5 is also preferably secured to the walls laminated material, comprising an outer layer of
