Description
This invention particularly relates to new and useful improvements
in cartons, and more particularly to the construction of a story
book type carton locking structure.
In accordance with this invention, an anchoring slot is provided
for a locking flap of the carton by the simple expedient of leaving
a portion of a securing panel of the support panel assembly free
and separate from an opposed surface of an adjacent outer panel of
the carton in the manner which in no way detracts from the
structural strength of the carton
A particular feature of this invention is to provide that section
of a story book type carton which is adapted to receive a locking
flap carried by the other section with an anchoring slot which is
defined solely by a free edge portion of a securing panel of a
support panel assembly and an outer panel of the first-mentioned
section, the free edge portion of the securing panel being held in
close proximity to the opposed surface of the outer panel by the
permanent securement of the securing panel to the outer panel and
by a strap which extends from the free edge portion to a further
panel of the support panel assembly, which further panel is secured
to the inner panel of the first-mentioned section.
Another feature of this invention is to facilitate the entry of the
locking flap into the anchoring slot by both holding the free edge
portion to a minimum width and by rounding the edge thereof.
A further object of this invention is to provide an efficient
locking flap in a carton of the story book type wherein the
anchoring slot in no way detracts from the appearance of the carton
or the efficiency thereof both as to the holding of a product and
the structural strength thereof.
With the above and other objects in view that will hereinafter
appear, the nature of the invention will be more clearly understood
by reference to the following detailed description, the appended
claimed subject matter, and the several views illustrated in the
accompnaying drawings.
In the drawings:
FIG. 1 is a perspective view of the carton in its open state
viewing the same from the interior thereof.
FIG. 2 is a fragmentary plan view of a blank from which the carton
of FIG. 1 is formed.
FIG. 3 is a perspective view of the carton of FIG. 1 in a partially
closed position, the closure panel and locking flap thereof being
still open, and a portion of the carton being broken away for
purposes of clarity.
FIG. 4 is a perspective view of the closed and locked carton.
FIG. 5 is a horizontal sectional view taken along the line 5--5 of
FIG. 4 and shows more specifically the details of the carton.
FIG. 6 is a fragmentary vertical sectional view taken along the
line 6--6 of FIG. 4 and shows particularly the details of the
locking structure of the carton.
Referring now to the drawings in detail, it will be seen that there
is illustrated in FIG. 1 a carton of the story book type, the
carton being generally identified by the numeral 10. The carton 10
basically includes a first section 11, a second section 12 and
intermediate connecting hinge assembly 13. Each of the sections 11
and 12 is adapted to have positioned therein a product 19 in a
manner wherein the product is attractively displayed and at the
same time easily removable from the section, but normally so
positioned therein so as to be retained against accidental
loss.
The carton 10 further includes a closure panel 14, which is carried
by the section 12, and which functions as a closure for the free
ends of the sections 11 and 12. The closure panel 14 terminates in
a locking flap 15 which is adapted to be received within the
section 11 so as to lock the carton 10 in a closed position.
The two sections 11 and 12 are substantially identical. The section
11 includes an outer panel 16 which has connected thereto a pair of
end panels 17 and 18. The end panel 18 has integrally connected
thereto an inner panel 20 while the end panel 17 has integrally
connected thereto a support panel assembly which is generally
identified by the numeral 21. The support panel assembly 21 is
secured both to the inner panel 20 at a point adjacent the end
panel 17 and to the outer panel 16 at a point remote from the end
panel 17. The constructiion of the support panel assembly 21 will
be described more in detail hereinafter. It is to be noted,
however, that the support panel assembly 21 defines a socket 22 for
receiving a product, such as the product 19. In addition, it is to
be noted that the inner panel 20 is provided with a cut-out in the
form of a displacy opening 23.
The section 12, being constructed very similar to the panel 11,
includes an outer panel 24, a pair of end panels 25 and 26, an
inner panel 27 and a support panel assembly 28.
The hinge assembly 13 includes a closure panel 30 (FIG. 5) which
permanently connects together the adjacent edges of the outer
panels 16 and 24. The hinge assembly 13 also includes a hinge panel
31 which permanently connects together the inner panels 27 and
which is provided with a central longitudinal hinge line 32 to
facilitate the movement thereof from a generally planar condition
as would occur in a fully opened position of the carton 10 and a
position folded upon itself, as is shown in FIG. 5.
The hinge assembly 13 further includes a pair of end panels 33
which are foldable from a position generally paralleling the
closure panel 30, as is shown in FIG. 5, to a position generally
normal to the closure panel 30 in the fully opened position of the
carton 10. It is to be noted that the uppermost end panel 33
interconnects the end panels 18 and 26 while the lowermost end
panel 33 interconnects the end panels 17 and 25.
At this time it is also pointed out that the end panels 17 and 18
are provided with closure flaps 34 and 35 which normally partially
close the open end of the section 11 disposed remote from the
section 12.
With particular reference to FIGS. 1, 3 and 6, it will be seen that
the support panel assembly 21 includes a generally U-shaped
securing panel 37 which is disposed in face-to-face relation to the
outer surface of the inner panel 20 and is adhesively secured
thereto. The support panel assembly 21 includes a second securing
panel 38 which is adhesively secured to the inner surface of the
outer panel 16 in a manner to be described in detail hereinafter.
The securing panel 38 has a lower centrally disposed projecting
portion 40 which is generally aligned with the recess in the
securing panel 37 and a connecting panel 41 extends between the
lower central portion of the securing panel 38 and the upper
central portion of the securing panel 37, the connecting panel 41
forming the sheet 22.
It will be readily apparent that the construction of the securing
panel 37 provides for a pair of upstanding legs 42 which are
disposed above and on opposite sides of the connecting panel 41.
The legs 42 have extending therefrom straps 43 which are disposed
at opposite sides of and above the connecting panel 41 and connect
the upper ends of the legs 42 to the securing panel 38.
It is to be particularly noted that the securing panel 38 has a
free edge portion 44 which is disposed in face-to-face relation
with respect to the inner surface of the outer panel 16, but is
free of any positive securement thereto. The other surface of the
free panel portion 44 and the inner surface of the outer panel 16
combine to define an anchoring slot 45 for the locking flap 15.
This is best shown in FIG. 5. In order to facilitate the entry of
the locking flap 15 into the anchoring slot 45, the free edge
portion 44 has a rounded free edge 46 which is disposed adjacent
the free end of the section 11. In addition, the securing panel 38
is notched as at 47 so as to restrict the height of the free edge
portion 44 and thereby further facilitate the entry of the locking
flap 15 into the anchoring slot 45.
With particular reference to the blank for the carton, which blank
is generally identified by the numeral 50 and is illustrated in
FIG. 2, it is to be noted that the portion of the securing panel 38
to the exclusion of the free edge portion 44 has that surface
thereof which opposes the outer panel 16 covered with a suitable
adhesive 51. Thus the free edge portion 44 is held in tight
face-to-face engagement with the outer panel 16 both by the
securement of the securing panel 38 to the outer panel 16 and by
the strap 43 which is connected at one end thereof solely to the
free edge portion 46. Thus the free edge portion 44 will receive a
clamped and locking flap 15 against the outer panel 16 when the
locking flap 15 is inserted into the anchoring slot 45.
With particular reference to the blank 50 of FIG. 2, it is to be
noted that the support panel assemblies 21 and 28 are disposed
along one edge of the blank 50 in transversely spaced relation. It
is also to be noted that the securing panel 38 is disposed along
the free edge of the blank 50 while the free edge portion 44 is
disposed at a corner of the blank 50. This permits the free edge
portion 44 to be separated and apart from the remainder of the
blank 50, as well as the remainder of the carton 10 except for its
connection to the adjacent portion of the remainder of the securing
panel 38 and to the associated strap 43. In this way the free edge
portion 44 may be configurated as desired to effect both the
desired clamping of the locking flap 15 when it is disposed in the
anchoring slot 45 and to facilitate the entry of the locking flap
15 into the anchoring slot 45.
It will be readily apparent from the foregoing description of the
carton 10 and the blank 50 from which it is formed that the
particular configuration and arrangement of the free edge portion
44 in no way detracts from the ornamental appearance of the carton
nor does it in any way detract from the structural strength of the
carton. On the other hand, it provides for the aforelisted
beneficial locking feature
Although only a preferred embodiment of the carton has been
specifically illustrated and described herein, it is to be
understood that minor variations may be made both in the carton and
the blank without departing from the spirit of the invention.
