((31. 93-391) The present invention relates broadly to the art of container manufacture;

' More'particular, this invention relates to' a container of conical configuration'con'strncted of paper, cardboard or the like carton'forming material and to the production ofsuchcontainers.

More particularly, this invention relates to'a'conical container of the materials above-mentioned adapted to befilled 'with milk or other preferably liquid contents.

*More specifically, the invention relatesto theproduction of a conical container, and'a resultant improved container, including particular shaping of the smaller end of the container into 'a' closure structure for this smaller end, facilitating the nesting of conical containers. Containers'ofthe type in question are generally formed from a preshaped fiat blank which is formed about'a conical mandrel'to tubular configuration and during which formation a longitudinal seam joins the opposite" ends of theblank. The thus formed conical "tubular body has its 'opposite'ends'closed by eitherinserting an end closure or by forming a folded closure at one end from the material of the'blank. v

Containers of this general description and adapted to contain milk or other liquids are'generally referred to as single use containers." Since they are to be used only once the conical configurationis 'of irnportance,- as it facilitates nesting of 'the containers; This factorproduces substantial savings in' connection with the storage and transportation of th'e'c'ontainers, particularly since the'containers are producedina'carton manufacturers plantan'dshipped to an' intermediate user who fills and closes the container, for example, a milk producing or distributing concern. I e

It has beenascertained that the nesting relationship of'conical' containers ha's"developed substantial difficulties. Due'to the conicity 'of the individual containers, the nesting thereof causes them' to wedge together, particularly adjacent the smaller bottomend. "This wedgin'g gives rise to difficulties inseparating the containers from nested relationship. In the event the containers are to be separated by mechanical means further difliculties arise." Moreover, the we'dging together of nested containers damages the layer of parafiin that has 'been applied, particularly to the interiors of-the containers, to render them water-tight. Thus the containers are subjected to leakage and; additionally, loosened particles of paraffin can remain on the interior of the containers and possibly 'pollute the liquid contents to be placed therein.

Accordingly, the present invention has for an object to provide an improved conical containerconstruction, with particular reference to the shaping and closing of the smaller "end t-hereofso' as to provide an internal supporting arrangement within one container that serves as a rest for the bottom of a container to be nested within the one container 50 as to prevent conatinersb'ecoming wedged together and'to' render them easily separable.

' Specifically, the-invention has for'anobject to'provide a method for producing such containers, including the formation. of an internal annular bead above, the 1 bottom of the 'containerand the reduction in cross section of the lower portion of the container in the areabelow thebead.

Still more specifically, the invention has for I anjobjeot "to'provide an end'structure arrangement for conical containers, including a redueed portion atfthe ;sn 1allerv end and an end closure, embracingftheieduced portion, including aside flange extending substantially perp ndicular *to the plane of the hottom .of the container and having an extent substantially corresponding to the axial extent of the reduced lower ,jportion offjthecontainer. Such an embracing bottom closure, including ia' flangesurrounding the lower reduced portion of the container body, facilitates the connection and assembly; ofjthe closure'to the body since this connection can be effectedby pressing and shaping tools acting exteriorly of the shaping mandrelwhich shapes the body. H

It an additional object to provide a 'coniical coritainer and method of producing thesame in which the r duced lower portion is so dimensioned relative to the remainder of the container body that'the exterior diameter of the embracing closure does not extend beyond the adjacent surface of the exterior of the containerfbody above theflange of 'the bottonrclosure. This assures that 'the' inner diameter'of the contai ner adjacent the inwardly protruding annular head is somewhat larger than the exterior'diameter of theclosure soth at a loose nesting arrangement of containers can be effectedg k I In order to turner protect the container against leakage and'to prevent entrythereinto of liquids; the .invention, as an additional object; provides a container end structure'which includes a flanged closure surroundingthe end portion'of 'the' tubular container body lwith therir n ofthe container body "having an inwardly extending shaped fold with the terminal edge of the container body directed laterally outwards so that this terminal edge abuts the interior of the fiange on the bottom closure. 1' In producing containers in accordance with'theteachings' of this invention th'ereis utilizeda conical s ping mandrel having a cylindrical endport'ion. The initially flat container'body blank'is' folded inaknown'rnanner about the conical niandreland'securediii'itubnlar'shape by the -formation of the longitudinal'seani of adhesive. Fornecking in or reducing the'end portion of the centainer about the reduced cylindrical'por'tionf 'of the inaiidrel, suitable drawing" tools"ar'e' pressed over the as sembled' body portion whileit is on the mandrel, renowing which an end closure is formed about the reduced portion of the body. j

Accordingly, the inventionhas for an"'objecf to pro; vide improvedmethods of constructing such a container closure arrangement, including simultaneous reduction in size of the end portion of the container about the mandrel and the formation 'of an embracing end closure from aplanar closure bla'nk." k

' Further and more specific objects will be apparent from the following description taken in connection with the accompanying drawings, in which: i Figure -l is a fragmentary vertical cross sectionalview ilustrating' the reduced end portion of a conical container and its associated closure structure, Figure 2 is a fragmentary view partly in longitudinal section illustrating a plurality of containers of the type shown in Figure tin nested relationship, w]

Figures 3 to 8 illustrate successive steps in the formation of the container end structure shown in Figure "1,

Figure 8a illustrates'the'step'of Figure 6 utilizing a partially preformed closure blank, r 'Figures 9 to 12 illustrate the various steps in a mo'dified method "of producing the container of Figure "'lf' Figure 12a isa view similar to Figure 1 but illustrating the container produced by the steps shown in Figures 9 to 12 on a reduced scale,

Figure 13 is a fragmentary longitudinal section on an enlarged scale illustrating a portion of the mandrel and a modified end structure arrangement including an inwardly directed U-shaped fold at the rim edge of the container body, and

Figures 14 to 18 illustrate diagrammatically and on a reduced scale the production of a container of the form shown in Figure 13.

The invention, as particularly shown in Figures 1 and 2, provides a container structure which includes a body 1 of conical shape, the larger end of which, after filling with preferably liquid contents, is closed by either an inserted closure, not shown, or by forming a folded closure from the material of the larger end of the body. Since the manner of closing the larger end of the container body is not part of this invention and is known in the art, the same is not illustrated.

Consistent with the objects of the invention, the important factor in connection with the conical containers that are to be nested is the elemination of the possibility of the containers wedging together in nested relationship. Accordingly, as shown in Figures 1 and 2, the smaller end of the container body is closed by a flanged or rimmed closure part 2, the flange 3 of which embraces the exterior of the coordinated portion of the smaller end of the container body, 'and is connected thereto by adhesive. In order to enhance the rigidity of the container the bottom closure is dished inwardly, as at 4. In other words, the plane of the major portion of the end closure lies within the perimetrical rim of the bottom of the body, the perimetrical rim being formed by forming the flange 3 about the end portion of the container body. As also shown in Figure 1, the smaller end 5 of the container body is reduced and deformed to cylindrical shape. The axial extent of the cylindrical portion of the container body corresponds substantially to the axial extent of flange 3.

Due to this reduction in cross sectional shape, there is formed an inwardly extending annular bead or projection 6. As shown in Figure 2, the bead 6 of the end container supports the perimetrical rim of the closure 2 of the next adjacent container. In this connection the exterior diameter of the reduced cylindrical portion 5 of the smaller end of the container body is so selected with relation to the conicity of the remainder of the body 1 that the exterior diameter of the flange 3 of the closure does not extend beyond the continuation of the conical side wall of the container body, whereby the containers can be nested one within the other without wedging together adjacent the bottoms as is customary with conventional conical containers where the side portions ,adjacent the bottom form continuations of the conical body.

In producing the container of Figure 1, the initial step is that shown diagrammatically in Figure 3, in which a flat blank 1 is placed about the conical shaping mandrel 7 the mandrel 7 having at its upper end a reduced cylindrical extension 8. The blank 1 is formed about the mandrel 7 and about the extension 8 of the mandrel in conformation to the shape of the mandrel. The ledge 8' on the mandrel insures the formation of the inwardly directed annular head or ledge 6 of the container body. Following the formation of the reduced portion 5 of the container body,

the annular drawing tool 9 is removed and, as shown in Figure 6, a closure member blank 2 is disposed above the mandrel 7. The blank 2 can be a planar blank as shown in Figure 6, or it can be a partially erected closure blank 2, Figure 8a, in which its flange 3 is partially formed. After the closure blank is positioned relative to the mandrel 7 a shaping die 10 is moved downwardly to press the blank onto the top of the mandrel which is dished so that the dished bottom 4 of the end closure is formed. While the blank 2 is being pressed against the top of the mandrel an annular drawing tool 11 moves downwardly to form rim or flange 3 of the closure and to conform and press this flange against the reduced cylindrical end of the container body so that, following the completion of these steps, the reduced end of the container body has the shape and internal configuration as shown in Figure 8.

In order to adhere the closure to the container body a thermoplastic binder is utilized which is applied to the blanks during their production. The strip of thermoplastic adhesive can be applied to the closure blank or to the outer portion of the container body adjacent the marginal edge thereof, or the adhesive can be applied to both blanks. The thermoplastic adhesive is activated and rendered adhesive under the influence of heat generated by heating elements, not shown, incorporated in the drawing and shaping tools. Since the use of heated shaping tools in container construction is old, the same have not been illustrated. If desired, a pressure activated adhesive can be employed, in which event the pressure generated by the annular drawing tool 11 would adhere the interior flange 3 to the exterior of the reduced portion 5 of the container body 1.

The method of Figures 3 to 8 embodies the step of reducing the end portion of the container body preliminary to applying and conforming the closure.

For simplifying the production, the method illustrated in Figures 9 to 12 can be utilized. In this alternate mode of procedure the initial step of deforming the end of the container body 1 about the extension 8 of the mandrel, as shown in Figures 4 and 5, is eliminated. Instead the container body blank 1 is formed about the mandrel 7 and has its opposite ends overlapped and adhered together to form a longitudinal seam so that it appears as shown in Figure 10. Following this, the positioning and deformation of the closure is effected simultaneously with the reduction in size of the end of the container body into conformation with the extension 8 of the mandrel. Thus, as shown in Figures 11 and 12, the closure blank 2 is disposed above the end of the mandrel 7 and the pressing tool 10 and annular shaping tool 11 are moved toward the end of the mandrel so that, as shown in Figure 12, the end of the pressing tool 10 forms a dished bottom of the closure while the annular tool 11 simultaneously forms the flange 3 of the closure and reduces the end of the body 1 to form the cylindrical portion 5 thereof about the reduced extension 8 of the mandrel. Figure 12a illustrates on a reduced scale the container resulting from the steps of Figures 9 to 12.

Figure 13 illustrates a modified form of container end structure in which the reduced cylindrical portion 5 of the container body is provided with a U-shaped fold to form an inwardly extending two-ply rim portion 5, the free edge of the container body being directed outwardly and embraced by the lower portion of the flange 3 of the closure 2. In producing the container of Figure 13 the blank 1 is folded about the mandrel 7 in a manner to leave a portion of the blank extending above the top surface of the reduced extension 8 on the mandrel. Prior to pushing and forming the closure 2 about the body 1 the projecting portion of the container body that extends beyond the end face of the mandrel is first folded inwardly and then outwardly so that the free edge of the container body is directed outwardly so as to be disposed against the inner surface of the flange 3 of the applied closure to prevent any liquid-passing into the interior of the container.

In effecting these folds a die 13 having an annular recess 12 at the bottom edge thereof is positioned on the end of the mandrel. This results in the formation of an annular groove extending inwardly from the perimeter of the end of the mandrel. Into this groove formed between the upper surface of the mandrel and the recess on the die the projecting portion of the end of the container body is pressed by means of grooving discs 14, only one of which is shown. These discs circulate on a circular track and, as shown in Figure 16, produce the U-shaped fold in the end portion of the container body. Following the formation of the end structure of the container body the closure blank 2 is deformed and applied about the end portion of the container body in the manner described with reference to Figures 11 and 12. Thus, as shown in Figure 17, the end of the container body 1 is still spaced from the cylindrical extension 8 adjacent the ledge 8'. The pressing tool 10 and the annular die 11 push the blank onto the rim of the container body as defined by the U-shaped fold simultaneously conforming the portion of the body about the extension to produce the reduced cylindrical portion 5 of the body and deforming the closure blank to form the flange 3 thereof.

It is therefore clear that the present invention provides an end structure arrangement for tubular container bodies which includes a reduced body portion adjacent one end, a closure having an outwardly directed flange or rim substantially coextensive in length with the axial extent of the reduced portion of the body and engaging and adhered to the reduced portion of the body, and in which the interior of the body has an annular bead extending completely therearound at the level of the end of the flange whereby the containers can be nested with the edge of the bottom of one container supported by the bead of the container within which it is nested.

The invention further specifically includes an arrangement in which the reduced portion of the container body includes a folded portion of U-shape configuration with the bight of the U inwardly of the wall of the container and the rim edge of the container body contacting the flange of the closure adjacent its juncture with the base of the closure.
