9 Claims.

Our invention relates to a channel vented box and has particular reference to a box of the type in which various live objects are transported, such as baby chicks and the like, and may also be used for other articles, as vegetables, fruit and the like, which require ventilation during the course of shipment.

Our invention has to do primarily with a box having inclined sides and ends, and a cover having a channel therein, which is so formed that the cover is locked in position. The channel may extend either horizontally or transversely of the box, with vent openings therein which are positioned in the sides and the bottom of the channel portion of the lid 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 are packed 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 is the provision of a vented channel box which is made of corrugated fiber board, solid fiber board, paper board or other similar material, which is shipped in fiat sheets and can be set up at the place where the box is intended to be used, by stitching, stapling or riveting, or by any other appropriate means, thus effecting a material saving in freight rates and allowing for easy transportion of the parts used for making the box.

Another further object is the provision of a channel vented box with inclined walls, providing a box which is tapered in a vertical direction, which is easy and simple to manufacture and easy for the user to set up and lock the cover to the body, both at the channel portion of the top and the ends of the cover, and with in-' clined sides of the box which efiectually provide means whereby air may be circulated completely around the box and pass in and out of the box without any of the vents thereof being closed, either by the piling of the boxes themselves on top or at the side of one another, or any 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.

Another and further object of our invention is the provision of a box having a channel formed in the upper edges of the sides of the box, with a cover therefor which is fitted into the channel and scored thereacross in such manner that the cover may be used as a hinge and one side of the cover closed while the other is opened, particularly for the filling and removal of chicks and the like from the box. This is particularly desirable, since in putting a large number of chicks in a container it is difllcult to keep them confined while the box is being filled or emptied, as the case may be.

This application is a continuation in part of our application Serial No. 57,773, filed January 6, 1936.

These and other objects of the invention will be more fully and better understood by reference to the accompanying sheets of drawings, in which- Figure 1 is a perspective view of our improved box, with cover applied thereto;

Figure 2 is an elevational view of the blank used for the formation of the container portion of the box;

Figure 3 is an elevational view of a cover of the box;

Figure 4 is a top plan view of the container portion of the box with the cover removed;

Figure 5 is a longitudinal sectional view on the line 5-5 of Figure 4; and

Figure 6 is a cross-sectional view on line 66 of Figure 4.

Referring now specifically to the drawings, in which like reference characters refer to like parts throughout, a blank, designated as a whole by the reference character I0, is shown having a bottom section II, end portions l2 and I3, and side portions l4 and IS, with longitudinally extending score lines l6 and I1 extending along the marginal edge of the bottom section H at the sides thereof and which intersect transversely extending score lines l8 and I9 which extend between the bottom section ll and the end portions l2 and I3. The score lines i6 and I1 beyond the intersection with the transverse lines l8 and I9 are inclined toward each other, with the score lines l8 and It] also inclined toward each other as they cross the sides l4 and I5 of the box, so that when the lower section of the box is fashioned into a receptacle, the sides It and I5 and the ends are inclined, preferably inwardly, thereby providing a receptacle which is narrower across the top than at the bottom, and is also less in length at its top than at the bottom. This order may be reversed if so desired in order that inclined sides and ends be provided.

Comer portions 20, 20 integral with the sides l4 and liand the ends l2 and i3 are provided having score lines 2| extending diagonally thereacross from the juncture of the longitudinally extending score lines It, If and the transversely extending score lines I8, I8, to substantially the corner portions of the box, dividing the comer portions 20 into sections 22 and 23. The sections 22 are cut along the line 23 in order to provide, when the blank is formed into a receptacle, a space between the ends l2 and I3 of the box and the portions 23 which are folded around the ends of the box, to receive the tucked-in end portions of the cover, as will be hereinafter described. Centrally located with respect to the side portions of the upper end of the box are wing portions 24a, 24a, which are out along their bottom sides and folded inwardly, with vertical fold lines 25 being provided which are inclined so the distance at the top is lesser thanat the bottom of these openings in the sides of the box and within which a'channel section of the cover is fitted when the box is in its assembled position.

The cover of the box is formed of .a blank designated as a whole as 28 and which has score lines 21, 21 extending transversely thereacross adjacent the ends of the box, with depending integrally formed portions 28, 28 being shown having rounded ends 29, 28, and with notches 33, 33 being provided between the body of the cover 26 and the portions 28, which, in effect, form tongues which fit over the ends l2 and I3 of the box blank and are tucked in between the ends l2 and I3 of the box and the corner sections 23, 23 when the box is assembled. The cover 26 is of sufficient width, as shown, to extend slightly over the upper edges of the sides I4 and I5 of the box, while the depending portions 28 are slightly less in width than the cover and fashioned to fit tightly against the side portions l4 and I5 and are held in frictional engagement over the ends of the box and form closure members to retain the lid of the box in closed position.

Other transversely extending score lines 3|, 3| are formed, extending across the mid-section of the box, with other score lines 32, 32 being provided so that in effect the section 21 is composed of lid- portions 33, 33, a bottom channel section 34, and vertically extending side channel sections 35, 35. The lid 26 when folded is bent along the fold lines 3|, 3| and also along the fold lines 32, 32, and when in position the side channel sections are inclined outwardly and seat against the angular fold lines 25, 25 in the side portions and against the wing portions 24a, 24a, the channel section thereby being wider at the bottom than at the top so that in effect the lid is secured to the container at the middle thereof and hinges along the fold lines 3|, 3|. Punchouts are provided both in the side sections, the bottom sect ons, the lid portions, and-also in the sides and ends of the containers so that with the tapered box and the vented channel, circulation of air to the inside of the container is still possible due to these vent openings regardless of how the containers are stacked. These punchouts are cut through but the portion of the box allowed to remain in the hole to be easily punched out by the shipper to provide proper ventilation, depending on the temperature 'conditions under which the chicks are shipped, and the like.

A longitudinal dividing wall 38 is provided having angularly disposed ends 31, 31 which are fitted against the end portions and stapled or otherwise secured to the end portions, while a transverse member 38 is provided having angularly disposed ends 33, 39 which are stapled or otherwise'secured to the sides of the box, thereby dividing the container into four compartments, the two walls 36 and 38 being cut one from the upper edge and the other from the lower and fitted together to form a sealing wall extending in both directions to the bottom of the container.

In manufacture of the box, the flats, such as H and 26, are manufactured and shipped to the user in bales or boxes in fiat condition. when the user desires to set up the boxes for use, the section II is folded along the fold lines I! and I1, and I8 and |9,and the corner portions 23 are thereupon folded upon themselves along the transverse fold lines 2|, and against the ends l2 and I3 of the lower section with the portions 23 being imposed upon the portions 22. Staples 43,

40 are inserted through the portions 23 and 22,

and the ends l2 and I3 of the box, the staples being inserted low enough to pass through both the comer portions 22 and 23, thereby fashioning a tapered box as shown in Figure 1. The outer ends .of the portions 22 being cut oil! on the line 23, a space is provided between the ends l2 and I3 and the portion 23 of the corners, within which portions of the cover 28 are tucked when the box is closed.

The dividing walls 33 and 38 are shipped in fiat condition and when the container is formed, as above described, they are placed in the container and have their ends bent and stapled to the sides andv ends of the container particularly as shown in Figure 4,,thereby dividing the bottom of the container into four compartments and also providing a strengthening means for the bottom of the container. The partition extending parallel with the channel is slightly lesser in height than the sides and the end, while the other partition is notched to receive the channel and extends up sufficiently high for the lid to rest on it when placed in position in the box.

' The wing portions 24a are folded inwardly along the lines 25. The cover portion is folded along the fold lines 3| and 32 so that the lower section of the channel portion is fitted on the upper edges along, the wing portions 24a, this channel section 34 being wider at the bottom than the channel is at the top so that the cover is held in position on the container when fitted against the undercut fold lines at the ends of the wing members 24a.

In this condition the box can be 'filled, one side being closed as shown when the filling of the compartments on that side is completed, and the other side left open until these sections have been filled, whereupon the cover is closed and the end members 28 turned downward and tucked into position over the ends l2 .and I3 of the box between the sections 23 and the ends of the box with a wedge fit, the cover being held closed by frictional engagement of the rounded ends of members 28 engaging against the sides I4 and I5 of the box adjacent the fold lines, with the corners of the box fitting into the notches 33, 30 in the lids, thus securing the box lid in closed position.

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.
