United States Patent 3,396,897 FIBERBOARD CARTON Gerald J. Bick, Berkey, and Willis J. Kirkbride, Toledo, Ohio, assignors to Owens-Illinois, Inc., a corporation of Ohio Filed Oct. 21, 1966, Ser. No. 588,618 4 Claims. (Cl. 229-32) ABSTRACT OF THE DISCLOSURE The invention in question relates to a corrugated board carton having a bottom portion, two side portions and two end portions, the side and end portions containing elongated vertical ventilation slots, the axes of which are parallel with the corrugated flutes of the corrugated board. The above-described arrangement for ventilation slots is advantageous in that it prevents the easy migration of moisture through'the corrugation flutes.

This invention relates to a fiberboard carton. More particularly, this invention is concerned with a fiberboard container which is particularly adapted for ventilation or drainage and which can be utilized in the presence of moisture or water.

The container of the subject invention is especially convenient to use and has exceptional strength properties. Likewise, the container of the invention at hand is novel in that it has ventilation slots in both its side and end panels, said ventilating slots all being parallel with corrugation flutes. The slots of the subject carton are referred to as ventilation slots, however, it is obvious that these slots can be used for either ventilation or moisture drainage. The ventilation slots of the subject invention are also unique in that they are positioned in such a way that upon bending a score line, the lower extremities of said ventilation slots are pinched closed.

As is discussed above, the subject container has ventilation slots in both its side and end panels. The prior art discloses containers which incorporate ventilation slots in both the side and end panels. However, in these prior art containers, one set of ventilation slots are always positioned at right angles to the corrugation flutes. A set of ventilation slots which are positioned at right angles to the corrugation flutes allows moisture to be transferred over a wide section of the corrugated board and hence allows the board to weaken and soften and therefore become useless in the presence of moisture. In contrast, the ventilation slots as incorporated in the container or the subject invention are all parallel with the corrugation flutes. Accordingly, when these ventilation slots are exposed to moisture, said moisture can migrate only through the channels which are actually cut at right angles to the corrugation flutes. This number never exceeds the number as actually covered by the width of the ventilation slot.

The ventilation slots of the invention at hand are also novel in that the lower extremities of said slots are arcuate, the radius of this are being positioned directly on a score line. When the score line is bent, the lower extremity of the ventilation slot is crimped so as to minimize moisture migration.

The primary object of this invention is the manufacture of a superior carton.

Another object of this invention is in the manufacture of a superior carton which has ventilation slots in both the side and end panels, said ventilation slots all being parallel with the corrugation flutes.

Still another object of this invention is the preparation of a container wherein the lower extremity of the ventilation slots are crimped by folding a score line.

Finally, the object of this invention includes all the ice other novel features which will be obvious from the drawings and specification at hand.

In the drawings:

FIG. 1 is a top plan view of the blank used to form the container of this invention.

FIG. 2 is a perspective view showing the container of this invention in its first assembly state.

FIG. 3 is a perspective view showing the container of this invention in almost complete assembly state.

FIG. 4 is a perspective view showing an end panel of the subject container in almost final assembly state.

FIG. 5 is a perspective view showing an end panel of the container of this invention in its final assembly state.

FIG. 6 shows the subject container in its final assembly state.

FIG. 7 is a perspective view showing the locking assembly of the subject container.

FIG. 8 is a perspective view showing the crimping action of the ventilation slots of this invention.

Referring to FIGS. 1 and 2, the subject carton is assembled by first gripping the inner central trapezoidal

end panel members

10 and 16 and folding them inwardly 180 onto bottom panel 2 along

score lines

62 and 72. Side panel 6 is then biased in relation to bottom panel 2 along score line 70 and intermediate inner end panels 60 and 56 are biased 180 along

score lines

66 and 74 onto central

trapezoidal end panels

10 and 16. While

panels

10 and 16 are trapezoidal in FIGS. 1 and 2, it is obvious to one skilled in the art that the panels could likewise be triangular.

In the above described folding procedure,

outer end panels

12 and 18 are automatically positioned at right angles to both side panel 6 and bottom panel 2 along

score lines

82, 83, 84 and 85.

Referring to FIG. 3, the above described assembly procedure is repeated wherein intermediate inner

end panel members

54 and 58 are biased 180 onto inner central trapezoidal

end panel members

10 and 16 on

score lines

64 and 76. This again automatically positions side panel 4 at right angles to bottom panel 2 along score line 68. Likewise outer

end panel members

8 and 14 are automatically positioned at right angles to both side panel 4 and bottom panel 2 along

score lines

78, 80, 86, and 88.

Composite folded inner end panel 90 and its opposing counterpart are now positioned approximately adjacent to bottom panel 2. Said composite panel 90 and its opposing counterpart are then folded 90 along

score lines

62 and 72 until parallel to outer

end panel members

8, 12, 14 and '18. Composite end panel 90 and its opposing counterpart are then secured in position by

tab portions

38 and 39 which, when placed through

handle apertures

42 and 46, are bent downwardly on score lines 91 through to secure the composite end portions into position.

Referring to FIG. 7, a locking tab 38 and its opposing counterpart 39 can be secured in position by use of staples, adhesives, etc.

Inner intermediate

end panel members

54, 56, 58 and 60 are provided with cut out

portions

104, 106, 108 and 110 which allow the panel members to be folded in accordance with the method described above.

The subject container incorporates a plurality of ventilation slots 18 through 28 inside

panel members

4 and 6. It is to be noted that these ventilation slots are parallel to the corrugation flutes as per cut-out 50. Likewise, a plurality of

ventilation slots

30, 32, 34, and 36 are provided in outer

end panel members

8, 12, 14, and 18. Again, it is to be noted that these drainage slots are parallel with the corrugation flutes as per cut-out 52.

As was discussed above, this arrangement permits maximum ventilation with minimal deterioration of the corrugated board due to moisture transfer through the corrugation flutes. This result is achieved due to the fact that a 3 minimal number of cuts are made at right angles to the corrugation flutes.

Likewise, as is best illustrated in FIGS. 1, 2, and specifically in FIG. 8, the lower extremities of all ventilation slots are arcuate. Specifically referring to FIG. 8, it can be seen that ventilation slot 20 has anarcuate periphery 102 which is positioned in close proximity to score line 68. When panel 4 is folded at right angles to panel 2, a crimping action occurs along score line 68. This crimping action tends to crimp arcuate periphery 102 in such a way as to minimize the transfer of moisture across the lower extremity of ventilation slot 20.

It is to be noted that while the preferred embodiment of the container of this invention has been illustrated, there are various modifications that would be apparent to a person skilled in the art. Also, it is obvious to vary the dimensions and relative size of the panels of the container to suit the particular application.

The container of this invention can be formed from any fiberboard of paperlike product. However, it is preferred that the container at hand he formed from corrugated board. The particular weight, corrugate flute, etc. of the corrugated board utilized will depend on the environment in which the carton will be subsequently utilized.

It will, of course, be understood that various details of construction can be modified throughout a wide range without departing from the principles of this invention and it is not, therefore, the purpose to limit the patent granted otherwise than necessitated by the scope of the appended claims.
