Dec. 12, 1950 N. F. DE LA FORET VENTILATED CORRUGATED BOARD CONTAINER Filed Juiy 16, 1949 jatentec Dec. 12, 1950 VENTILATED CORRUGATED BOARD CONTAINER Norman F. De La Foret, Toledo, Ohio, assignor to The Ottawa River Paper Company, rioledo, Ohio, a corporation of Ohio Application July 1e, 194,9, serial No. 105,121

' (ci. 22e- 6) 3 Claims. l

This invention relates to containers, but more particularly to containers of corrugated sheet material. In certain instances, it is quite desirable, and even imperative, that the inside of containers be ventilated. This has, in the main, been accomplished by providing holes through the walls of these containers, but in some instances, this is decidedly impractical and unsatisfactory. Holes of this character which provide openings directly to the inside of the container enable dust, dirt and foreign particles to rind their way inside so that the goods may be unsightly or otherwise rendered unsatisfactory.

Another objection to forming these holes in container walls is that they weaken the walls and in some instances that has mlitated against their use. Thislatter objection is particularly outstanding in the case of containers or cartons made of corrugated board of the usual type made up of a sheet of corrugated paper interposed between paper sheets or liners. It is accordingly a desideratum to provide a closed carton or ccntainer of corrugated board having breathing properties such that exchange of air between the inside and outside of the container may be indirectly effected without substantially weakening the container walls or exposing the inside of the container directly to the outside.

An object is to overcome the above diliiculties and to produce a container of corrugated board s perforated in such a manner as to permit exchange of air between the inside and outside of the container in an indirect manner and without appreciably weakening the walls of the container.

Another object is to provide a container of corrugated board having perforations so constructed and arranged as to enable the container to breathe and of such form and arrangement as to enable same to be ei'liciently and economically produced in quantity production.

Other objects and advantages of the inven tion will hereinafter appear, and for purposes of illustration but not of limitation, an embodiment of the invention is shown on the accompanying drawings, in which Figure l is a view of a carton or container of corrugated board and provided with rows of apertures affording ventilation or breathing of the container;

Figure 2 is an enlarged transverse sectional View substantially on the line 2-2 of Figure 1;

Figure 3 is an enlarged transverse sectional View on the line 3 3 of Figure 1; and

Figure 4 is an enlarged vertical sectional view on the line 4 4 of Figure 1.

The illustrated embodiment of the invention comprises a carton of corrugated board having side walls lf3, bottom wall E l Aand top closure flaps I 2, the structure being old and well-known in the art and provides a closed container for receiving merchandise for shipping or storage purposes. Corrugated paper board is old and Wellknown in the art, and as shown on Figures 2 and 3, consists of an intermediate layer or ply i3 of relatively heavy corrugated paper, in this instance the corrugations extending vertically of the carton shown in Figure l. On opposite sides of the corrugated sheet i3 are relatively thin paper sheets or liners, there being an inner liner i4 and an outer liner it which are adhesively and intimately adhered to the intermediate corrugated liner. Since the characteristics and properties of this corrugated board are wellknown to those skilled in this art, further description is not considered necessary.

Before the corrugated board is folded to form the container7 rows of relatively small holes or perforations It are formed in any suitable manner. On the outside of the corrugated board and as shown on Figure 3, the holes not only pass through the outer liner sheet E5 but also through the corrugated sheet i3, but do not entend through the inner liner llt. perforations it are arranged in a straight line and equi--distantly spaced from each other. rihus it will be observed that the perforations do not pass through the saine portion of the corrugation in each instance, but for practical purposes it is suhcient that the perforation extend through the outer liner and the corrugated sheet. At the saine time, it is just as important that these perforations do not pass through the inner liner i4, the reason for which will hereinafter appear. The number and spacing of these sheets of corrugations may be varied as desired. Preferably the row is interrupted at intervals thereby to militate against weakening of the side walls or panels of the carton.

Spaced above the rows of perforations it and on the inside of the corrugated board are rows of periorations il which penetrate through the liner i and the corrugated sheet i3 but do not penetrate the outer liner i5. The row of perforaticns il may, in production, be formed concomitantly with the forming of the periorations i5 and generally speaking, a perforation il in the upper row corresponds to and is in alignment with a perforation it in the lower row of perforations so that a perforation EE and a perforation il will each perforate the same hill or val-l ley of one of the corrugations which in this instance it will be understood extend vertically from top to bottom of the side walls of the carton.

Figure 4 illustrates by arrows the movement of air from the outside of the container or carton to the inside, air passing through a perforation le through the outer liner and corrugated sheet and into the channel formed between the corrugated sheet and the inner liner i4, thence upwardly and out through the corresponding perforation il in the upper portion of the container wall. Manifestly, this air movement may be reversed allowing air from the inside to pass to the outside. This in effect enables the closed interior of the container or carton IG to breathe, the series of periorations on the inside and outside comniunicating through the channels formed by the intermediate corrugated layer and ythus allowing exchange of air.

The advantages of this construction have been heretofore pointed out but may be briefly sumniarized as foliows. The container is allowed to breathe but the dust and dirt from the outside can not find they way to the inside because of the tortuous air channels. The structure of the carton is not weakened to any appreciable extent nor are the perforations at all unsightly and, finally, the perforations of the above character can be formed in large scale production efficiently and economically and do not in any Way interfere with the scoring of the board in the formation of the carton blank. This latter feature is shown in the drawings in which a portion of the row of perforations is on one side of the score line and a portion on the opposite side.

It is to be understood that numerous changes in details of construction, arrangement and choice of materials may be effected without departing from the spirit of the invention escially as defined in the appended claims.

VWhat I claim is:

1. A container comprising a body of corrugated sheet material having an intermediate ply provided with a series of elongate corrugations 4 interposed between and connected respectively to relatively flat inner and outer liner plies, a perforation penetrating only the inner liner ply and the corrugated ply, and another perforation penetrating only the outer liner ply and the corrugated ply, said perforations penetrating the same corrugation by spaced points thereby to enable an exchange of air between the inside and outside of the container through said perforations and the channel formed by the respective corrugation.

2. A container comprising a body having side and end wall panels thereby to provide a closed package, said body being of corrugated paper and having an intermediate sheet provided with longitudinally elongate corrugations and inner and outer liners adhesively secured thereto, and a pair of spaced rows of inside and outside perforations, the perforations of each row penetrating only a single liner and corresponding corrugations thereby7 to provide tortuous air channels between the inside and outside of the con- 3. A container comprising a body having side and end wall panels thereby to provide a closed package, said body being of corrugated paper and having an intermediate sheet provided with longitudinally elongate corrugations and inner and outer liners adhesively secured thereto, and a pair of spaced rows of inside and outside perforations, the perforations of each row penetrating only a single liner and corresponding corrugations and each perforation having a lateral dimension less than the width of a corrugation, thereby to provide tortuous air channels between the inside and outside of the container.
