2 Claims.

This invention relates to shipping cases or packages, and particularly to such as contain canned goods. It is customary to ship canned goods in packing cases, the walls of which are formed of corrugated paper or other more or less flimsy material and these walls do not offer resistance to external pressure on the case, as a result of which the bodies of the cans in the cases are frequently bashed in -and dented in 'such a way that they are unsightly and more or less unsaleable.

One of the objects of this invention is to produce a shipping package for canned goods having simple means inserted in the case with the cans to attain a reinforcing effect and prevent, as far as possible, injury to the cans from external pressure on the case. 'Ihe invention is particularly applicable where two or more tiers of cans are packed into the case, and one of the objects of the invention is to provide simple, inexpensive means capable of being packed into the box or case with the cans and operating to brace the side walls of the case between the top and bottom of the case, and also operating to brace and reinforce the vertical corners of the boit or case.

Further objects of the invention will appear hereinafter.

Ihe invention consists in the novel parts and combinations of parts to be described hereinafter, all of which contribute to produce an emcient shipping package.

A preferred embodiment of the invention is described in the following specifications, while the broad scope of the invention is pointed out in the appended claims.

In the drawing:

Fig. l is a plan of a shipping package of canned goods, embodying my invention and showing one of the flaps of the cover closed and the other ap open; one of the open flaps is broken away. This View represents a box or case with the lower tier of cans within the same, and represents a horizontal partition wall broken away at an intermediate point.'

Fig. 2 is a vertical section taken on the line 2-2 of Fig. 1, but showing the cans adjacent the side walls that are shown in section, broken away to further illustrate reinforcing stringers or angled pieces that I employ in the corner of the box.

In practicing the invention, I employ a shipping case of the usual box form having bottom and side walls. The top, bottom and side walls of this box have a certain degree of stiffness, but

lll

Jill

(Ul. 22g-ll 5) are of insumclent rigidity to prevent the cans from being subjected to damaging pressure through the side walls.

The cans that are packed into the case are arranged in tiers laid progressively upon the bottom, and in the present instance I have illustrated the invention as applied to a box or case which is merely deep enough to accommodate two tiers or layers of the canned goods. In accordance with my invention, I provide a horizontal bracing partition located between the tiers of cans, which partition substantially ills the hori- Zontal cross section of the case. In addition to this, I provide means cooperating with this horizontal partition for distributing its pressure against the side walls and for incidentally reinforcing the Vertical corners of the case.

Referring more particularly to the drawing, l indicates a shipping case of box form having a bottom il and vertical side walls il. rI'he bottom n 2 may be of a single piece of material, or it may be composed of flaps tu., 2b, which are hingedly connected to the bottom edges of the side walls and which overlap each other to form a complete box.

'I'he cover of this box as illustrated has the same construction as the bottom. That is to say, it comprises two oppositely disposed flaps 42 and two oppositely disposed flaps tb which are all folded down so as to overlie each other when the box is closed for shipment. Within the box or case, I pack a plurality of canned goods of any kind. The cans b are laid as indicated in Fig. 1, so that they substantially fill the box or case bali full, but before putting the cans in the case I provide the four corners B of the case with reinforcing strips l. These strips may be formed of stout cardboard, or similar material, and each strip comprises a central web 8 and flanges d. At the junction between the flanges and the webs, the material is creased and offset to enable the anges to be folded against the side walls of the box to form a tube of triangular cross-section having a space l0 within the same. This channel enables the material to bend readily without any danger of breaking. After the bottom layer of the cans has been put in place, I lay upon the same a horizontal partition wall Il. This partition wall has corners with rounded edges I2 which fit against the outer faces of the webs 8 of the corner strips. The partition ll substantially fills the horizontal cross section of the case and it will be evident that if pressure is exerted upon the vertical side walls of the case, this pressure will be resisted by the partition wall ll, the

dit

rigidity of which substantially assists the side walls in resisting such a pressure. In this way, unless the force is very great. the cans within the case will be protected against dents.

Furthermore, it will be evident that the strips I at the corners of the box very substantially reinforce the corners and also operate to take the pressure of the partition I I and distribute it over 'considerable area on the inner faces of the vertical side walls.

The webs 8 may also be engaged by the sides of the cans, thereby assisting the side walls in holding the cans in place.

It will alsobev evident that the corner strips I and the horizontal partition wall I I are very inexpensive and do not materially increase the cost of the shipping case; at the same time they very substantially increase the resistance oi' the case to external pressure on its side Walls.

What I claim is: l

1. In a shipping package for holding a plurality of cans of canned goods disposed in tiers, the combination of a box-form shipping case having a bottom and side walls of insufficient rigidity to prevent the cans from being subjected to a damaging pressure through the said side walls,

and a substantially horizontal rigid partition wall located between the tiers of the canned goods, substantially filling the horizontal cross-section of the case and bracing its side walls against external pressure, and an angle-form corner strip disposed in each vertical corner of the case ex- -tending past the said horizontal partition and engaging the edge faces of the corners of said partition wall, said corner strips operating to engage the faces of the adjacent cans, and also operating to center the partition wall and distribute the pressure oi.' its edges against the corners of the case.

2. In a shipping package for a plurality of cans of canned goods disposed in tiers, the combination of a box-form shipping case having a bottom and side walls of insuilicient rigidity to prevent the cans from being subjected to a damaging pressure through the said side walls, and a substantially horizontal rigid partition wall located between the tiers of the canned goods, substantially lling the horizontal cross-section of the case and bracing its side walls against external pressure, and angle-form corner strips disposed in the vertical corners of the case engaging the edge faces of the horizontal partition, each corner strip having fianges resting against the inner faces of the side Walls and having a web connecting the iianges, engaging the faces of the adjacent cans in said tiers and extending across the vertical angles of the case, said partition having rounded corners engaging said webs, said corner strips operating to center the said partition wall and protect the corners of the case from the same.
