to open the cover.
55
All of the body forming panels 5, ‘I, 8 and 6,
_
'
4—3 of cover panel 6 are overfolded on to the
end ?aps 4-—3 of bottom panel ‘I, and thus the
2,114,134
end closing flaps are all secured to permanently
seal the ends of the carton.
As thus erected and sealed, the carton has a
permanent end seal, a temporary cover tuck flap
seal and a cover panel-weakened connection on
its opposite ends to its adjacent outer end clos
ing flaps 4—-3.
To open the carton, a knife blade, or similar
member is entered into the crack between the
10 outside face of the inwardly disposed tuck flap 2
forming element having a means for forming a
temporary glue lap which is convertible into a.
carton reclosing tuck ?ap.
.
Having thus described the invention what is
claimed is;
_
1. A carton formed of a blank of paper board
comprising bottom and top panel members hav
ing coacting front and rear side members, op
posite ends consisting of ?aps which extend from
weakened lines of weakened resistance A—-A are
broken and the tuck flap and cover 6 grasped
together and the front member having at the top 16
thereof a ?nger space, said front member having
by the ?ngers by reason of the cut-out l,
as
as lines of weakened tear resistance, a single
wall forming element convertible into a cover
and the inside glue resist face of panel 5, and
by running the knife blade along the seam be
tween edges a and I 2, the glue seals of the spots
a are broken from glue stripe G, then the two
and the cover 5 is opened as in Fig. 2, the rear
score line b acting as a hinge therefor.
20
herein, but all of the modi?cations are directed
to structures having features in common, such
When desired, the cover 6 may be reclosed, by
tucking tuck flap 2 back into its original posi
tion in the carton.
The cartons of Figs. 4 to 6 inclusive are made
up of substantially similar construction as the
carton of Figs. 1 and 2. In the Figs. 4 to 8 in
elusive, like indices are used to indicate parts of
similar or like nature in Figs. 1 to 3.
The difference of the carton structure of Fig. 4
over Figs. 1 and 2 lies in the outside lapping and
30 gluing of the sealing tuck ?ap 2, using spaced
glue spotting G, to seal the flap 2 to the outer
face of panel 5. The temporary seal spotting G
may be accomplished as described for Fig. 3, or
the glue spots G may be printed on directly.
35
A further difference in the carton of Fig. 4 over
the carton of Fig. 1 is that the lines of weak
ened resistance A—A of Fig. l have been altered
_ on Fig. 4, and, as in said Fig. 4 and Fig. 8, the
cover panel 6 has the lines of weakening C—C
arranged to converge, across the surface of panel
6 starting at the opposite, outer ends of the tuck
panel 2, at its score line a, curving slightly in
ward, and then passing backwardly in two con
verging straight lines of perforation C--C and
45 ending at the cover score line b.
As thus shown in Fig. 4, a knife, or similar
edge is passed up under edge g of flap 2, and the
spotted, temporary seal G broken, then the cover
panel 6 is broken at its lines of weakened con
50 nection C—C and opened on its hinge score I),
leaving two end reinforcing panel ?aps E-E on
opposite ends of the carton.
Fig. 6 combines the feature ofthe modi?ed
lines of weakened resistance C—C of Fig. 4 with
55 the feature of the tuck ?ap 2 being temporarily
sealed inside of panel 5 as in Fig. 1.
Fig. 5 has all of the structural features of Figs.
1, 2 and 6, with the exception that the cover
panel 6 has converging lines of weakened tear
60 resistance B—-B, similar to C—C of Fig. 4, but
these lines B-B terminate short of the rear score
line b, and are intersected by a hinge score
line D, all disclosed in the blank layout of Fig. 7.
As thus shown, when the inside tuck ?ap Z is
65 released and the lines B—B broken, the cover
panel 6 is lifted, as indicated by the dot-dash
lines of Fig. 5 leaving reinforcing portions E--E
on both ends of the carton, which merge into and
join the rear reinforcing portion F, Fig. 4, thus
70 leaving the side and rear wall portions 3—6 and
8 well supported.
It will thus be observed that while the single
piece blanks of all of these cartons are quite
similar, and the functions are the same, some
76 structural features vary in the modi?cations
said members, said ?aps being permanently glued
on inner face a glue strip, and a tuck lap extend
ing from the front edge portion of the top panel
and having on one face thereof spaced glue re
ceiving spots, said lap being innermost and the 20
spots being engaged with the glue to form a seal,
said top panel having therein weakened lines
which extend backwardly from the ends of said
front edge portion, said lines forming end bound
aries of a closure, whereby said faces may be 25
readily urged apart to break the seal, so that
said lap and the top panel may be manually
grasped at the finger space whereby to open the
closure, the structure being then also broken
on said weakened lines.
30
2. A carton formed of a blank of paper board
which is cut and scored to provide bottom, and
top panel members having coacting front and
rear side members, opposed ends consisting of
?aps which extend from said members, said ?aps 35
being adhesively attached together and the front
member having at the top thereof a ?nger space.
said front member having on its inner face aglue
strip, and a tuck lap extending from the front
margin of the top panel and having on the 40
outer face thereof glue receiving spots, there
being glue resisting material on the other por
tions of said latter face, said lap being inner
most and the spots being engaged against the
strip to form a seal, said top member having
therein two weakened lines which extend rear
ward from the ends of said margin, there being
a hinge line connecting the rear ends of the ?rst
line, said lines being boundaries of a closure,
whereby said faces may be urged apart to readily 50
break the seal, so that said lap and the top mem
ber may be grasped at the ?nger space whereby
to open the closure, the structure being then
also broken on said weakened lines.
3. A carton according to- claim 1, wherein the
weakened lines are inclined inwardly from their
front ends and are spaced from the ends of the
carton, there being portions of the top panel

adapted to form ?nger supports while the closure
is being opened.
4. A carton according to claim 2, wherein the
closure member is reclosable, the tuck lap beingv
again engageable inside of the front side.
.
5. A paperboard carton comprising bottom and
top panel members having coacting front and
rear side members, opposed ‘ends consisting of
?aps which extend from said members, said ?aps
being attached together at the respective ends, 70
said front member having at the top thereof a
?nger space, said front member having on its
inner face a glue strip, and a tuck lap extending
from the front margin of the top member and
having on the outer face thereof glue receiving

said spots, said lap being innermost and the spots
end members cooperating with the ?rst end mem
being adhesively engaged on the strip to form a
means detachably sealing said front wall and
bers, a closure ?ap extending from said rear wall
and having a tuck lap on its front part, and

line connecting the rear ends of the ?rst lines, glue receiving spots on the front face of said lap,
said lines de?ning a closure and there being 'a said spots being in registry with said strip and
top area outside of said lines, whereby said faces ‘ there being glue resisting material on the face
10 may be urged apart to readily break the seal, of said lap so as to provide said spots. ‘
so that said lap and the top member may be
9. A carton made from one piece of paper
