The invention relates to containers -and more particularly -shipping -vessels, suchfas barrels or the like used for the transpontationland storage ofl corrosive, tastesensitive -and valuable-lling materials- In'order to dispense withtheuse `of expensive materials, namely aluminum," copper, pure nickel," noni-corrosive steel'rnetalfalloys 'andfthe like, containers have been'produced which consist of an inner sleeve orshell and outer bracing elements. -The' outer-bracing elements replace the previously employed louter container, but, it lwas ascertained that the youter bracingelements (steel reinforcements) were not! sucienft ltoprotect'the inner container made of expensive material from external destruotive'actions. f Hence, the wall of 'theinner container had .to be made stronger, and, the cost of the same exceeded substantially the production costs of the outer container. To the extent that enclosures of synthetic material, cardboard, rubber and the like were used for a thin-walled inner-container or shell, the Wall thickness of the outer envelope or enclosure, in view of the high resistance Vrequired by the entire container was such that the-increased cost ofmanufacture was prohibitive. This is especially true of'enclosures of a` synthetic material as suitable synthetic materials are tool expensive respecting purchase and processing for oontainers.

Furthermore, a container has been heretofore provided which consists of a barrel having a metal or` synthetic material lining and the foil is in the nature of a bag which is inserted into the outer container. v v

Outer containers made of steel do not, however, satisfy the requirements since in filling and dispensing corrosive materials, contact of the iiillingv material with the outer container cannot be avoided. This results 'in a premature destruction of the outer container by a corrosive action and the inner container or lining fails to protect the assembly against damage as' cracks and the like are easily formed therein.

The above and other objectionable characteristics are overcome according to the present invention. Toproduce the present invention, there is provided an inner sleeve or shell, preferably of corrosion-resistant metal or homogeneous synthetic material and the wall thickness or cross section is quite thin. Bnacing reinforcements of a less expensive or non-corrosive resistant substance which are subjected to external mechanical stresses are provided for the inner sleeve and such reinforcements are in the nature of head rings and annular hoops by means of which the container can be rolledalong a supporting surface. A layer of synthetic material is applied, preferably in a liquid state TorA in a state permitting kneading throughout the entire assembly. After thislatter layer has set or hardened, a'V rigid iand insoluble joint or h l the assembly.

Moreover, it isalso possible that the reinforcement can be lirst placed on the inner sleeve or shell and the cavitiesof the reinforcement filled by pouring an ad-` hesive filler therein. ,After the filler is set, it joins the reinforcement and inner sleeve.

j" Anotherf embodiment includes the concept vthat the lled'head reinforcement, the bottom bunghole and the 'wall yare applied lto the 'inner sleeve, and, ythe outer sleeve or shell ofsynthetic material is the'n secured. "Atthe mid-zone and atboth sides, the syntheticcoating is Wider' Yand thicker thereby achieving'the additional rigidity.

1 To 4avoid deformation`- of :the inner sleeve or shell,

prior fto or'during application of the synthetic material, or during pouring, fthe inner sleeve is filled with a gaseous or liquid medium, and, safety means regulating the pressureareemployed; y Y. I l i 'y Between the reinforcement andthe inner sleeve, a layer of synthetic material `in a liquid state or a state allowing kneading, may be applied so that after setting, a rigid, insoluble medium results.` Y

The -synthetic material can be applied as an outer sleeve in one or more layers and intermediate the layers, ller or bracing layers ofjminenal fiber, wrapping paper, brous substances, textiles or /wire netting can be arranged. f f' f The synthetic material canI becolored -by the addition of the desired color medium Vvand the drying or setting can be accelerated by'a' convenient heat treatment.

Between the Ithin-walled innersle'eve or shell and the reinforcements, a synthetic substance can be positioned,-

and, this is especially true of containers in Which the reinforcements are hollow rolling hoops and'head hoops.) In addition, reinforcements such as aibunghole' ange, name plates, advertising plates `and the like can be united by the use of synthetic materials without the employmentY of other means.

The outer wall of the container can be bulged, and, hollow hoops having la liller can be provided at the ends and the side wall with-the inner sleeve and reinforcements secured together by an louter sleeve of synthetic material. At the upper end and in the mid-zone thereof, the synthetic layer is-thickened and'surrounds the bunghole unit carried by the inner sleeve, and an annular ring also cooperates with the bunghole unit to additionally retain suchrunit.

The lower end Aof the inner sleeve-or shell can be arched and surrounded by an arched synthetic coating. Adjacent to the -bung-hole unit carried by the side wall ofthe inner shell, the outer synthetic layer is thickened to compensate fo'rthe bung-hole unit and adapt the same union is effected between the reinforcement and the inner ,sleeve or shell thereby,attaining ,the required mechanical resistance necessary by thel container. v i v Lt is also possible to produce a container having equivalent characteristics by placing the inner sleeve, preferably centrally in aniold andthe intermediatespace bounded section of one form of the invention. '1 t fingered MayV 9, 1961 Figs. 2 and 3 are fragmental views in vertical cross section of further forms of the invention.

Fig. 4 is a vertical sectional view of a fragment of the upper end of a container illustrating the mode of reinforcing the bung-hole unit. v

Fig. 5 is a vertical sectional View of a barrel having bulged side walls constructed in accordance with the Vinvention.

Fig. 6 is a fragment of -a barrel with bulged side walls showing in vertical cross section, a further form of the invention and,

Fig. 7 is a vertical sectional view of yet another form defined by an inner shell and a cast outer wall.

As shown in Fig. 1, a container C is defined by an inner sleeve of shell 1 of very thin ycross section and the shell is provided with an annular hollow hoop 2 and hollow end or head parts 3. The hoop 3 allows the container to be easily rolled on its side along a surface while the end parts permit the ready movement in the vertical or substantially vertical position.

Intermediatek the inner shell 1 and the end parts 3, there is iirst applied a synthetic material 4 and this material layer defines a joint therebetween. An outer relatively thin-walled layer of synthetic material 5 is -then applied to the assembly, with the material either in a liquid state or a state allowing kneading. When the layer 5 has set or hardened, it surrounds the sleeve or shell 1 together with the hoop 2 and the end parts 3 thereby holding the respective parts together.

Together with the reinforcements and the inner sleeve A 1, the synthetic layer 5 includes a substantial portion of the supporting member, and, this portion can be increased in the manner shown in Figs. 2 and 3. specifically, this is effected by arranging between two or more synthetic layers 5 and 7, an intermediate layer or layers 8 of the required thickness, and, such intermediate layer can be fibrous material, paper, cardboard, mineral fiber and the like. In addition, less expensive material, such as wire netting of ifine or coarse mesh can be employed for the intermediate layer.

In Fig. 4, there is illustrated a manner in which a bung-hole unit is attached to the container. It will be More seen that an internally threaded ring 9 of the same matev rial as the shell 1 is reinforced by a bung-hole ring 10 which is covered by a layer of synthetic material :11 thereby permanently connecting the parts with the inner shell 1, and, the connection is improved by interposing a synthetic layer between the sleeve 1 and the ring 10.

Fig. 4 further shows how a name plate or an advertizing plate 12 can be simultaneously secured to the assembly.

It will be appreciated that the container is very sturdy, presents a smooth surface, and, if desired, the synthetic layer can be colored to suit requirements of the purchasers. Furthermore, valuable material is saved, and, depending on the use of the container, a considerable range of synthetics can be employed. The synthetics may be either very hard or elastic, such as PVC or polyester bases.

In Fig. 5, there is depicted a barrel B wherein the side wall is bulged, and, is of a type commonly used for malt beverages, such as beer and ale. In this form, a thin-walled inner shell 13 of metal or synthetic material is provided at its ends with vhollow reinforcing rings 14 ,and the cavities of the rings contain a filler material 15. The inner shell 13 and the rings 14 are entirely covered by a layer or sleeve 23 of synthetic material and in the mid-zone of the assembly, the layer is thickened to provide a band 16 and adjacent to the ends, the layer is thickened to form bands 17 which are slightly less vin height than ithe vcentral band 16. The dimensions of `the bands 16 and 17 are-determined in accordance with the stresses which will beimposed `on the b arrel, and, .the wide ,band 16 is primarily Vused in connection with beer barrels.

A synthetic coating '18 at the upper end of the barrel is of greater thickness at the centralpart; anda'bunghole unit 19 is arranged at the central part. A reinforcing ring 20 sur-rounds the bung-hole unit and serves to anchor the unit in proper position.

A bung-hole unit 21 i's'provided for the side wall of the barrel, and, it will be noted ythat the inner shell 13 is planar adjacent the unit 21 as indicated at 22 so that at this area, the outer. synthetic layer is materially thick# ened at 36 in order tocompensate for the length of the bung-hole unit 21. The lower end of the inner shell 13 is arched, and, the. outer surface thereofis covered with a synthetic layer 24 and is of a thcknesscorrespending tothe load-imposed onA -the lower endA of 'the barrel. p f y I i( In Fig. 6 is illustrated a modified container in which inner shell 13 is provided with reinforcing steel hooplike members spaced along the Yside wall and such niembers are identified 2 5 andy '26,. The cavity of themember 25 located at lthe central zone of the wall is filled with suitable filler material 28, and, the Acavities of the members 26 positioned on opposite sidesof the member 25 `contain similar ,ller material 27. A,Outer wall 23' of `synthetic material includes the metal hoop-like mem-bers2Sand26. l Y Fig. 7 shows a vessel V having a thin-walled inner shell 29 provided withr recesses 30 for bung-hole units. Outer sleeve `31 is formed by casting and -isisuch athickness as to satisfy the requirements which are made `on the vessel. Hoops 32 and end projections 33 are preferably formed during casting or in any other suitable manner vand the end of the bung-hole recess 30 is `surrounded `bycasting flange 34. `In order to strengthen the hoops 32 of the outer shell 31, lreinforcing inserts 35 of steel and the like may be cast in the shell.
