UNITED STATES CHANNEL-VENTED BOX John P. Brunt, Chicago, and Edward E. Maston, Wilmette, Ill., assgnors to Brunt & Company, Chicago,Y Ill., a corporation of Delaware Application January 6, 1936, Serial No. 57,773

-3y Claims.

y Our invention relates to a channel vented box and has particular reference to a box of the type ifnfwhich various live objects are transported, such as baby chicks and the like, and may also beused for, other articles, as vegetables, fruit,

and the like, which require ventilation during the course of shipment.

yOur invention has to do primarily with a box having a cover with one or more channel portions therein which may extend either longitudinally or transversely of the box with vent openings in the channel portions so that regardless of how these boxes may be packed during the course of shipment, there is an opportunity for the free circulation of air from the inside of the box and regardless of how other boxes or cartons arefpacked at the sides of the container or on top thereof, the vents will not be closed nor the circulation of air prevented even though the boxes may be stacked in close formation.

' Another and further object of our invention isithe` provision of a vented channel box which isY made of corrugated' vfiber board, solid ber board, paper board or other similar material which is shipped in flat sheets and can be set up at rthe place where the box is intended to be used by taping, stitching, stapling or riveting, or by any'otherappropriate means, thus foregoing a material saving in freight rates and allowing for easy transportation of the parts used for making the box. y

*Another and further object is the provision of a box in which the sides are formed of a double thicknessof material, adding to the strength of L," the boxjandiprovides astrong durable box which eli'ectually' protects 'the contents of the box during transportation.

Another further object is the provision of a channel vented box which is easy and simple to manufacture and which eiectually provides means whereby air may pass in and out of the box without the vents thereof being closed, either by the piling of boxes in among other boxes, or by piling material on top of the box, as is usually the case in ordinary boxes of this type in which vent openings are provided.

These and other objects of the invention will be better understood by reference to the accompanying drawings, in which- Figure 1 is a plan view of the blank forming the lower or container section of the box;

Figure 2 is a plan view of the blank for the top of the box;

Figure 3 is a top plan view of the box in assembled relation;

Y Figure 4 is a longitudinal sectional View on line 4-4 of Figure 3; Y Y,

Figure is atransverse sectional view on line E--E of Figure 3.

Referring now specifically to the drawings and in which like reference characters refer to like parts throughout, a blank II is shown from which the lower section of the container is formed, this blank being fashioned from corrugated ber board, solid fiber board,paper board or like material, having longitudinally extending fold lines I2 and I3 thereinv which extend for the full length of the blank and transverse fold lines I4 and I5 extending partially across the blank whereby abottom portionY I6, side portionsfl] and I8 and end portions I9 and 20 are formed. The fold lines I4 and I5 extend only partially across the blank in a transverse directionV and are of a length equal to the widthof the bottom portion I 6 and end portions I9 and 2B. rAt the corners of. the blank extension members 2l, 2| are formed, by being severed from the side portions Il and I8 but areintegrally formed with the end portions I9 and 2.0. In each of the end members I9and 2B at the ends thereof in the blank (upperedges of these members when the box is in formed position) Aare rectangular shaped Ycut- outs 22, 22, these portions being out free on two sides but are preferablyleit attached to the Vend sections at the oppositesides andare turned inwardly when the lower section of the box is in its nal form. The lower sectionor receptacle portion of the. box is' formed by folding the side members Il'vand I 8 along the'fold lines I2'and/I3 to a vertical position, thereafter folding-theend'members I9 and 2D into a vertical position, and then folding the extension members 2! longitudinally against the side portions I 'l and I8 so that they are in face-to-face relation therewith, the ends of these extension members 2I meeting in substantially abutting relation. Gummed strips 23, 23 are placed in vertical position overlapping the ends of the members 2| and are carried around to the bottom of the box for a substantial distance, particularly as shown in Figures 3 and 4. Other gummed strips 24, 24 are placed over the registering upper edges of the side portions I'I and I 8 and the extension members 2 I, thereby providing a lower receptacle which has double side Walls and is quite strong and substantial to withstand weight placed upon it and rough handling in transportation. In each of the end portions I9 and 20 circular partial punch- outs 25, 25 are provided, these partial cut-outs being left intact in the blanks and substantially cut through so they can be easily punched out to provide adequate air circulation as desired by the shipper, depending upon the temperature, climate, distance of travel and the like, when the shipments are made. For example, if the `temperature is low, a less num ber of these punch-outs will be made so as to allow circulation of. the air through the ends of the box but restricting such circulation to a certain extent, whereas if the temperature is higher, more of these punch-outs can be made, leaving a larger number of holes for the more free circulation of air.'

The blank for the lid of the box is illustrated particularly in Figure 2 and comprises a flat rectangular shaped section 26 of the same material as that of which the bottom section is made. Extending longitudinally of the member 26 are fold lines 21 and 28 with intermediate fold lines 29 and 30, and outer fold lines 3l and 32, whereby when the cover 26 is in position on the receptacle, channels along the box will be formed, consisting of outer strips 33 and 34, bottom strips 35 and 36, and inner wall strips 31 and 38. The outer strips 33- and 34 and. the inner wall strips 31 and 38 form the vertical sides of each of the channels, while the strips 35 and 36 form the bottoms of each of the channels. The width and height of these respective channel sections correspond to the depth and width of the struck-out portions 22 in the end portions I9 and 20 of the box blank I I so that when these channel sections are formed, they project into and are supported by the end portions I9 and 20 of the box and the outer sections 33 and 34 are in vertical relation and rest against the inner sides of the side portions I1 and I8. In sealing the box a gummed strip or the like can be placed over the edge of the strips 33, 34 and the upper edges of the portions I1 and I8 and over the gummed strip 24, whereby effectively sealing the two sections of the box together after the contents has been placed therein for transportation and the like. Punch-out sections, such as 25, 25 are placed in rows in each of the inner side walls and'bottoms of the channel portion of the lid, which may be removed in the same manner and under the same circumstances as the punch-outs heretofore described in the ends of the container. Particularly it will be noted that these punchouts in the sides and bottom of the channel portion of the cover are in such position that they cannot be closed by another box or container placed on top of a receptacle such as we have described and if these containers are placed in close relation with other boxes, an opportunity for the passage of air is always afforded in the channel formed in the cover of the box.

It is believed that the description heretofore made is adequate to show the construction and assembling of the container and that further detailed description of the assembly thereof would be merely repetition and is unnecessary.

While we have described more or less precisely the details of construction, we do not wish to be understood as limiting ourselves thereto, as `We contemplate changes in form and the proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit or scope of our invention.

We claim:

1. In combination, a receptacle having bottom, side and'end walls, the end walls having struckfout portions at the upper corners thereof whereby openings are formed in said end Walls, thestruck-out .portions remaining connected to said end wall at one of their sides, and a cover thereforhaving fold lines extending longitudinally thereof whereby channel portions are formed adapted to be litted into the openings in said end walls, each channel comprising two side walls and a bottom wall, the outer wall of each channel portion being tted against the adjacent side wall, the opposite side wall and the bottom wall having partial cut-outs therein.

2. A receptacle comprising, in combination, a. bottom section and a cover therefor, the bottom section having a bottom and enclosure walls, one pair of oppositely disposed enclosure Walls having recessesv formed in the upper outer corners, the cover having channel sections at opposite edges thereof, each channel section comprising two vertical side walls and a bottom Wall, 'the outer vertical side walls being tted against the face of the adjacent enclosure wall.

3. A receptacle comprising, in combination, a
