8 Claims. (Cl. 53-—381)
As shown in FIG. 1, the ?ap holding device 5 of the
invention is inserted within the small opening between
the overlapping ?aps 4 of the carton 1 and is adapted to
This invention relates to a ?ap holding device for
cartons and more particularly to a device for ?rmly

The ?ap holding device 5 includes a thin elongated
outer tube 6 having a pair of diametrically opposite slots
7 which extend substantially the length of the tube. The
upper end of the tube 6 is threaded and is received within
Cardboard cartons are generally fabricated with an
open top and four ?aps are folded over to enclose the
open top of the carton. The normal procedure in joining
the ?aps together to seal the container is to staple or 15

which is adapted to be inserted within the carton through 30 through the slot 7. The ?ngers of the operator are
the opening between the folded ?aps. A collapsible wing
is folded against the thin tube when the same is inserted
within the opening between the flaps, and after the wing
has passed within the container it is automatically ex
panded to a position generally normal to the axis of the 35
tube. In addition to the collapsible wing, at ?xed wing is
also connected to the tube which is biased against the
outer surface of the flaps so that the flaps are ?rmly
held between the inner collapsible wing and the outer
wing. With the ?aps held in this position and supported 40
by the inner wing, the ?aps can be readily stapled to
gether by use of a stapling gun.
The present device is easily inserted within the open
ing between the folded ?aps and will not enlarge the
opening to any extent. The ?aps are ?rmly held in the 45
overlapping position by the wings which [are located on
‘ the inner and outer surfaces of the ?aps. While held in

the ?ngers upwardly against the palm of the hand which
engages the hand knob 9, the slide 13 and rod 6 will be
drawn upwardly within the tube against the force of the
spring 14.
An annular collar 16 is slidably disposed around the
rod 11 and a spring 17 is disposed between the collar 16
yand the slide 13 and functions to bias the collar down
'wardly toward the lower end of the rod. A pair of wings
18 are secured to the collar 16 and extend outwardly
through the slots 7.
A yoke 19 is pivotally secured to the slide 12 by a pin
20 which extends through the slots 7. A pair of wings
21, similar in construction to wings 18, are secured to
the yoke and in the ?ap holding position extend normally
to the axis of the rod 11 and are displaced 90° from the
wings 18. To maintain the Wings 21 in’ the extended po~
sition normal to the axis of the rod 11, a coil spring 22 is
disposed around the pin 20 and one end of spring 22 is
