Application September 23, 1941 Serial No. 412mm 3 Claims. (cl. 229-55) This invention relates to containers of the character wherein the side walls thereof are constructed of laminated paper or other similar materials, and has for the primary object the provision of means for joining the layers of the side walls together at the upper and lower edges thereof, providing efiicient reinforcing binders and portions for the adapting thereto either metallic compression type end walls or heads or metallic seam tight end walls or heads to assure against leakage of the contents of the container and which will readily compensate for the different co-efllcient of expansion between the side walls and the end walls or heads.

With these and other objects in view as will become more apparent as the description proceeds, theinvention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a vertical-sectional view illustrating a container constructed in accordance with my invention.

Figure 2 is a fragmentary plan view illustrating one of the reinforcing binders.

Figure 3 is a fragmentary vertical sectional view illustrating a portion of one of the layers of the walls of the container and a reinforced binder prepared ready for application thereto.

Figure 4 is a view similar to Figure 3- showing the securing of the reinforcing binder to the layer.

Figure 5 is a fragmentary vertical sectional view illustrating the layers of the walls secured together by the reinforcing binders and the application thereto of a seamed end wall or head and the layers of adhesive for joining the layers of the walls together and a protective coating applied to the innermost layer of the walls. Figure 6 is a view similar to Figure 5 showing thecompression 'type of end wall or head in applied position Figure 'l is a view similar to Figure 5 less the protective coating and the liner layer shown in Flgurefi.

Referring in detail to the drawings, the numeral 5 indicates the vertical walls of a container. The vertical walls are composed of laminated layers of paper or similar material, as shown at i, and also a layer of lining material I. The liner I may be of any material suitable for the purpose and may be varied in accordance with the contents of the container. Engagingwith the laythrough the layers will acter of 'the contents of the container. Also ers Ii are metallic reinforcing strips 8 which pro-' ject beyond the end edges of said layers 6 and have struck therefrom a plurality of tines or teeth 9 which may be arranged at right angles thereto for penetration of the layers 6 and then are bent or clinched, as clearly shown in Figure 7, for the purpose of firmly securing the metallic reinforcingstrips to the layers of the walls Certain reinforcing strips or-the ones secured to the outermost layer of the walls are bent angularly, as shown at I 0, to extend over the end edges of said outermost layer and into tight engagement with the other metallic reinforcing strips or the portions thereof which extend beyond the layers.

Adhesive H may be applied to the layers Ii as well as to the layer 1 for causing said layers to adhere together when brought in tight engagement with each other.

Reinforcing binding strips of metallic material.

are applied to the liner 1, as shown at l2, and are crimped thereagainst as indicated at- I3. The metallicreinforcing strips protrude beyond the end edges of the walls 5 as well as'the liner 1 and are bent at right angles, as shown at II, and bear tightly against some of the other metallic reinforcing strips. The right. angle bends ll of the metallic reinforcing strips l2 extend in the direction of the bends III of the strips 8 so as to overlie the end edges of the liner as well as some of the layers 6.

The protruding portions of the metallicstrips are compressed tightly together to form metallic" may be apend edges to the container on which plied end walls or heads I5. The end walls or heads i5 may be of the compression shown in Figure 6, or the seamed type as shown in Figures 1, 5 and 7, it being understood that this latter 'typeare sealed by solder or similar material. Also as shown in Figure 1 the metallic strips 12 may be folded over the free edges of the metallic strips 8 assisting in'holding the metallic strips 8 tightly, together and providing eflicient bearing surfaces for the, end walls or heads to seat upon.

In adapting the metallic reinforcing strips 8 to the layers'i of the wall they be so located that the tines when passed other. e

If the liner 1 is not employed in the construction of the container, the innermost layer 6 may have applied thereto a suitable protective coating which would be in accordance with the chartype,as

it is preferable that not be opposite to each,

when the liner I is not employed the innermost metallic strips 8 take the place: of the metallic reinforcing strips l2 and are bent accordingly, as will be seen with reference to Figure 7.

Referring to the drawings and the foregoing description it will be seen that a very efllcient container has been provided wherein the vertical walls thereof may be economically manufactured through the use of laminated layers of paper or similar material and that a very efficient means is provided for the securing of said layers in their end edges and which act for the mounting of end walls and heads to the vertical walls to assure against leakage and to compensate for the different co-efllcient of expansion between the side walls and the end walls or heads, and also will permit different types of end walls to be applied or utilized such as the compression type or the seamed type.

While I have shown and described the pre-,

I claim is:

1. In a container, laminated layers of material forming side walls of a container, a liner engaging the innermost layer, metallic reinforcing strips secured to the laminated layers and protruding beyond edges thereof and bent to engage each other, and metallic reinforcing strips engaging and clinched to the liner and protruding beyond edges thereof and bent to engage and overlie the other metallic strips coacting therewith in forming mounting forend walls.

2. In a container, walls including laminated layers of material, reinforcing binding strips arranged about and in contact with the layers of the walls and projecting beyond end edges thereof to provide portions bent to contact each other and parallel with one another forming internal and external'shoulders with the internal shoulders providing seats for heads extending over and engaging with said strips, and tines on said strips passing through the layers of material and clinched thereagainst.

3. In a container, walls including laminated layers of material, reinforcing binding strips arranged about and in contact with the layers of the walls and projecting beyond end edges thereof to provide portions bent to contact each other and parallel with one another and forming internal and external shoulders, tines on said strips passing through the layers of material and clinched thereagainst, and binding strips arranged in and secured to the innermost layer of material of the walls and bent to conform to said portions of the first-named strips and bent to overlie and engage said portions.
