No. 99,742 Claims priority, application Germany May 4, 1960 3 Claims. (Cl. 93-39.1)
The present invention relates to a container of conical configuration constructed of paper, cardboard and similar carton-forming material in which the smaller end thereof is closed by a flanged or rimmed component surrounding such smaller end and with the flange of such component engaging the outer surface of the Wall of such smaller end and a method for making such container.
The object of German Patent No. 961,053 is principally directed to the shaping of the container wall edge which is enclosed by the flange of the closure component, and which is connected thereto by an adhesive. Particularly in situations in which such containers are used for receiving liquids such as milk and the like, the same are made of coated paper or cardboard, and the cut edges which come into contact with the liquid in the container presents a problem insofar as liquid may enter the wall of the container through the unprotected cut edge, so that the container will not be liquid tight in the Zone of the seams, especially in the zone of the connecting points between the container wall and the closure component.
To avoid a penetration of the liquid contents into such cut edge of the container wall edge surrounding the closure component flange, it has heretofore been proposed to turn down the edge of the smaller end of the container wall by providing a groove extending entirely about such wall. In this situation it was effected that prior to positioning the closure component over the open end of the wall, the edge of the wall which projects beyond the shaping mandrel is formed by a suitable rotating grooved tool, so that the upper end of the wall is initially folded inwardly approximately 90 and thereafter folded outwardly approximately 180. In addition to the fact that this type of folding necessitates increased costs in production, the two-fold shaping of the wall subjects the fibres of the container material to excessive wear and strain, thereby causing a breaking and formation of cracks in the Zone of folding.
In order to overcome the foregoing objectionable features, the present invention is directed to the concept of folding the upper edge outwardly prior to positioning thereon the closure component, in such afashion that when the closure component is applied to the open end one face of such outwardly folded portion lies against the outer surface of the container wall while the other surface is in facial contact with the inner surface of the flange of the closure component to secure a suflicient coverage of such folded over edge by the closure component, and to obtain an effective connection between the wall and the flange of the closure component, the flange is of greater width than the width of the folded over portion of the wall.
To provide the connection between the wall of the container and the closure component, the upper edge of the wall which projects beyond or above the upper end of the shaping mandrel, is initially folded outwardly approximately 90 for providing an uninterrupted rim extending about the entire periphery of the container wall and following positioning of a flat blank which forms the closure component of such outwardly folded portion, the outwardly folded portion or rim is folded inwardly approximately 90, and at the same time the flange of the closure component is formed.
3,118,351 Patented Jan. 21, 1964 The foregoing takes place at two successive work stations at the first of which the edge of the container wall is folded or bent outwardly at an angle by a shaping die or tool adapted to move upwardly and downwardly, with the edge of the jacket extending above the upper face of the shaping mandrel and at the second station the flat blank for providing the closure component is positioned on the outwardly folded edge, and the flange of the closure component is formed by means of an annular drawing tool which is also moved upwardly and downwardly, and during this latter step the complete folding of the wall edge is accomplished. 7
Further objects and advantages of the invention will become more readily apparent from the following description and annexed drawings, and in which drawings:
FIGURES 1-5 illustrate diagrammatically the sequence of steps for forming the container, and for making the closure for the smaller end or bottom of the container, and,
FIGURE 6 is a fragmental view in cross-section on an enlarged scale, illustrating the points of connection between the wall of the container and the closure component.
The invention provides a container structure which includes a body 1 of conical shape. The body 1 is formed from a pre-shaped, flat blank which is positioned about a conical shaping mandrel 2, having at its upper end a reduced extension 9 and during which formation a longitudinal seam joins the opposite ends of the blank. The larger end of the container, not shown, is closed by either an inserted closure or by forming a folded closure from the material of the larger end of the body. The formation of the larger end of the container does not form a part of the present invention, and for this reason the same is not illustrated.
To produce the closed smaller end of the container, it will be noted in FIGURE 2 that the free edge of the smaller end of the container body indicated 3 projects above or beyond the upper face of the reduced extension 9 of the mandrel 2. A shaping die or tool 4 mounted above the mandrel 2 is adapted to move toward and away from the mandrel, and when the tool 4 has moved towards the mandrel, the tool will fold the edge 3 outwardly approximately to provide an uninterrupted rim extending about the periphery of the smaller end of the body as best illustrated in FIGURE 3. The tool 4 is then moved away from the mandrel 2.
The container thus formed is then brought to a station employing a second tool assembly which includes a pressure punch or tool 5, and an annular drawing tool 6, as
clearly illustrated in FIGURE 4. A flat blank 7 which provides a closure component is positioned over the outfolded edge or rim 3 of the container body. Upon down ward movement of the punch or tool 5 the blank 7 is initially fixed in position, and thereafter the downward movement of the annular drawing tool 6 folds the edge or rim 3 inwardly approximately 90, and at the same time forms flange 8 of the closure component. At the same time, due to the reduced cylindrical portion 9, the edge of the wall will be of reduced diameter.
With reference to FIGURE 6, which shows On an enlarged scale the points of connection between the upper edge of the wall and the closure component, it will be noted that the width of the flange S is materially greater than the width of the folded over edge or rim 3, thereby providing an effective juncture between these particular components, and also forming a liquid-tight joint.
The securing of the components may be accomplished by means of a synthetic coating of the blanks, with the coating becoming effective under the influence of heat and pressure. The heating of the synthetic material coating may be achieved by heating elements (not shown) embedded in the shaping or drawing tools.
The invention is not to be confined to any strict con formity to the showings in the drawings, but changes and modifications may be made therein so long as such changes and modifications mark no material departure from the spirit and scope of the appended claims.
