This invention relates to container ticularly to ber containers, the object being to provide an improved simpliiied container which presents a maximum strength with a minimum amount of material.

Another object of the invention is to provide a container formed wholly of fiber and constructed to present an exceptionally strong structure at both ends.

A further object of the invention is to provide an all fiber container having a minimum number of elements, yet presenting a strong type ofconstruction at a minimum cost.

Another object is the provision of an improved 1 5 container formed'principally of fiber and .con-

structed to be appreciably reinforced at each end and at the same time present a light structure which is proof against-leakage of the contends, whether wet or dry, as well as proof against y the loss or admission .of moisture.

An additional object is to provide an improved container wherein the parts are formed principally of ilber, and also wherein the closure may be removed and again re-applied and re-sealed Without injuring either the container or the clo- Sure.

closure for containers of formed and molded i'lber construction with superimposed air-proof or moisture-proof material to make the fiber heading and closure proof against the passage of gases, oils or moisture through the closure of the container, combined with superimposed imper-v vious' materials between the .laminations of the Wall oi containers, thereby providing a strong and light container, highly resistant to the entry or escape from the container of moisture, gases or liquid materials.

.Referring to the accompanying drawings, Figure 1 shows a container embodying the invention where all the parts are ber except the adhesive and the fabric strips i and 2. 35 These strips are held in place by suitable adhesive and connect the head 3 and the bottom t respectively to the body 5. The body 5 may be a single piece of molded ber, or may be laminated as shown in Figure 2. Also, if desired, 40 under some circumstances, the body E may be made of some other material and yet the head. 3 and bottom 8 and other parts function as shown in the drawings and hereinafter fully described. 45

The respective ends of the container are identical, that is, head 3 and bottom 4 are made identical and are held in place in anidentical manner, if desired. However, ordinarily a layer of glueor other adhesive 6 permanently con- 50 nects the bottom 4 to the body 6, while the head 3 is held in place by friction and by the textile fabric i and the adhesive coacting therewith. If desired, however, adhesive could be used for assisting and holding the head or closure 3 in 55 place. As the head or closure 3 and the bottom l or other Water-proofvmaterial Ill is of the same size as the layer 1. When the parts have been formed into a closure, as shown in Figure 2, the smaller disc 'I and the Cellophane" I Il will ex-` tend across the main or outer part of the closure l and upwardly and over the end of the body of the container but not downwardly onzthe outside.

As shown in Figure 2,'the upper surface of the body I5 of the closure 3 will be concave. However, in`some of the closures, the upper surface of the section is straight. In Figure 2, the body I5 has been shown as concave. This is desirable in that it helps to distribute the strain from the body of the container in casethe container when filled is dropped and strikes on either end. The strain will be distributed radially to the body 5 and unless the-strain is sufciently great to rupture the parts, it will be taken up and sustained by the body 5. It is possible that under these circumstances the body portion I5 may bulge outwardly, but as soon as the pressure is relieved it will automatically go back to its normal position as shown in Figure 2, thus maintaining a proper sealed condition.

As shown in Figures 1 and 2, the container is formed with a body of laminated material and one of the layers, namely, layer I3, is formed of Cellophane or some other moisture-proof and air-proof material. By this construction and arrangement the inner wall I4 of the closure 3 braces the end of the body 5 in one direction, while the outer wall or flange I'I braces or holds it in the opposite direction. In order to permanently hold the closure in place, a textile fabric strip I is placed in position, as shown in Figures 1 and 2, the same having been applied with some sort of adhesive as, for instance,rglue. When providing the strip of fabric I, the same may be cut on the bias and, consequently, comprises a bias strip which when `applied has the ability of adjusting itself to hug or come in intimate contact with surfaces having different diameters. For instance, the section or portion I' fits smoothly and tightly the outer wall I'l and the portion or section Il nts the body 5 which'is of less diameter. In this way a snug t of the strip of fabric is secured throughout without` any tendency of puckering, If desired a strip of stretchable material not cut on the bias may be used and good results secured.

When it is desired to open the container and consequently remove the closure 3, a knife may be run along thepart 20, and usually there is a slight space beneath this portion so that the knife may readilyv cut the fabric without injuring any of the other parts. The closure 3 may then be pulled oi to secure access to the contents. If desired, the closure may be again placed in position and another strip of fabric I applied, whereupon the container is reclosed and re-sealed.

' what may be termed an all fiber container.

In Figures 3 and 3a a modified form'of the invention is shown wherein the body 2l and also the ends are formed square. 'I'he ends are con-l structed identical with those-shown in Figure 2 except that they are square. When these ends have been removed, or before they are applied, the body 2| may be collapsed, as shown in Figure 3a, so that a number of thecontainers may be shipped in this collapsed form and set up at their destination, thus economizing on the space used during their shipment. It is to be understood that the same -combination of a collapsible shell or body may be used with cylindrical or other shaped containers by the proper creasing or forming of the shell so that it may be collapsed 'and when vopened form the desired shape'. Where the container is cylindrical or some other shape, the top and bottom 'closures or end members will be of that shape and will permanently hold the body in that shape when applied.

Figure 4 shows a modified form of the invention -wl'iich'is in most particulars identical with that shown in Figure 2, but modified to provide a bunghole or opening, the same being provided with a metal, fiber, rubber, or other sleeve 22 held in place by friction and by adhesive. terior of the sleeve 22 is threaded for receiving a threaded plug 23. In this form ofthe invention, the Cellophaneor other moisture-proof member 24 is not arranged between the layers of the body portion I5 but on the 'bottom thereof, so that when a water-proofing coating 25, as, for instance,.as phalt is poured in through the openingV formed by sleeve 22, said liquid may be distributed over the bottom and sidewalls of the container, and also, over the closure 3. As illustrated, the coating adheres to the "Cellophane 24, which Cellophane" is unattached to the head 3 except by the sleeve 22. The coating 25 connects with the Cellophane" 24 and forms an annular thickened portion 25 merging into a side Wall covering 21. This structure is desirable in .that it makes the container absolutely moisture-proof, and in addition, the end coating 25 is not attached directly to the closure 3 so that if the container'should be dropped, and the closure 3 should become injured and somewhat loose, it would not break the seal because the coating 25 and the Cellophane 24 would merely move away from the closure 3 without breaking any part. If desired, a similar coating could be provided for the struc- In Figure 5 a further modified form of the invention is shown which is similar to Figure 2 except in two particulars, one being that the textile fabric retaining strip 28 extends over the top and ture shown in Figure 2 except for the closure 3.

down into the chime of the closure 3, so that the y inner wall or section 23 may be secured by adhesive to the wall I4. The other point of difference is the provision of extra layers 30 of fiber in the body portion I5'but not in the walls I4 and I'I. This adds additional reinforcement against collapsing of the container.

Figure 6 discloses a'modiiied structure to those heretofore described'but is formed to secure substantially the same result in bracing and sealing action, but in thisform of the invention, the closure 3 is formed with two layers, as, for instance, layers 3| and 32, which extend straight lacross from one side of the container to tie other and then downwardly to form the outside flange or wall I 1'. I'his outside wall or ange is secured by the fabric strip I, as 4illustrated in Figure 2. However, the inside part is constructed differently -from that shown in Figure 2in that the Cellophane" or other' moisture-proof sheet 33 extends ilatwise across the container and immediately below the layer 32, and below the Cellophane" 33 is another layer of fabric 34 which rests on top of the body 5 of the container. Thisbody may be identical with that shown in Figure 2 or may be made thinner or thicker vas desired. In order to provide the inside bracing desired, layers of ber 35 and 38 are provided, the same being bent down at the periphery for forming a depending flange 31 tting tightly against the inner surface of the body 5'. In this way there is an inside and an outside brace or holding structure acting to resist inward lstrain and outward strain in a similar manner to that shownin Figure 2 but-- with a. different structure. After the parts have beeny formed in suitable dies, they are assembled and held together by adhesive, the adhesive between the layers 3| and 32 being preferably placed on the fiber before the fiber disks are bent and the same is true in respect to the fiber disks 3i and 3'6.

In Figure 7 another form of the` invention is shown wherein a closure is provided having a top portion 38 formed of two sheets of fiber bent s to provide a depending flange or outer wall I1. A single layer 39 is secured to these two layers by adhesive and extends over the top of the body -5 but not over the outside surface thereof. Be

low the i'lber strip 39 are a plurality of. disks 40,

the disks being held together by adhesive, and` beneath the lowermost, there is arranged a sheet 4I of Cellophane or other moisture-proof material which extends from one side to the other of the container upwardly along the vwalls of the container ,and then over the top edge thereof, whereby the parts are sealed against the en-v trance or loss of moisture and atthe same time' is provided inside and outside bracing members to resist expansion or compression in a similar manner to the way the closure 3 resists expansion or contraction, though by a different construction. i

Figures 8 and 9 show a further modified form of the invention wherein the parts are constructed identical with that shown in Figure 2 except that the chime is of greater depth so that the upstanding rim 42 may be bent over as shown in Figure 9, thus forming an interlocked reinforcing and sealing structure 43.

In Figure 10 the same structure as shown in Figure 8 is disclosed but instead of lbeing turned over, as shown in Figure 8, the parts are pressed so as to be deformed inwardly along a central line 44, thus preventing providing an additional contact seal and a reinforcing structure.

In the form shown ln- Figures 9 and 10, the closure when completed acts as a locked structure and must be destroyed to a greater or less extent in order to secure accessto the interior of the container.

In Figure 11 a fragmentary view is shown wherein the same is similar to the upper part of Figure 2 except that instead of using the fabric strip I, one or more metal strips 4B are used. The strip as shown in Figure 1-1- is provided with a number of spurs 46 at the lower end adapted to be pressed into the body 5 while the upper part ts over the outer wall Il, extends across the top of the rim 42 and then downwardly presenting a hook-shaped extension 41 having spurs 4I pressed into the material for locking the metal 'strips in place and for locking the closure against accidental removal. When itis desired to remove the closure, member 41 is pulled outwardly and /swung over toward the left as shown in Figure 11, until the closure is free, whereupon it may be pulled oif the body 5.

In Figure 12 a further form is shown which is l similar to Figure 11 but instead of using a metal strip a number of clips 49 are provided, each clip having a pair of spurs 50 adapted. to be forced into the ring 42", thus locking the closure against accidental removal.

An additional modified form is shown in Figure 13 wherein the structure is the same as in the upper part of Figure 2, and also the same as shown in Figures 11 and 12 except that a row of stitching 5I extends horizontally through the ring 42"'. This provides an effective lock forthe closure so that the same cannot be removed without destruction orwithout removing the stitching. j

Figure 16 shows a top plan view of a slightly modified form of cover wherein the straddling member of the structures shown in the other forms may be used, but .various `radiating reinforcing ribs have been provided so as to' stiiien the center of the cover.

In all forms of the invention no metal is use except in the forms illustratedin Figures 11 and 12, and the metal used in these figures Is merely to lock the closure in place and is not essential to the proper sealing and reinforcingof the container.

InFlg. 14 will be seen a structure similar to that shown in Fig. 8 except that itis used at the lbottom of. the container and is provided with a line of stitching extending through the container and the thin outer wall 0f the L ieshaped 'Strade dling member.

In all forms of the invention except that shown in Figures 6 andv 7 there is provided a chime `in each end of the container which keeps the material in the container away from the floor upon 'which the container may rest, and this structure presents also great flexibility as well as great strength so that severe internal or external shocks are cushioned, and thereby the material in the container is protected and also the body portion of the container is protected vagainst fracture by reason of the reinforcing functioning of the ends.

In any form of the invention it is intended that the chimes at either end of the container may be coated with cellulose or other hardening material or covered with a thin form of metal in order to secure .these chimes from wear and to add strength thereto.
