UNITED STATES PATENT OFFICE.
EDWIN F. HULBERT, 0F MILWAUKEE, WISCONSIN, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO THE MASTER PACKAGE CORPORATION,
0F DELAWARE.
Application mea october 21, 1972-5. serial No. 63,906.
rIhe invention relates to containers, and more particularly to fibre containers, and the method of making and securing the bottom head to the siding forming the body or cover of such containers.v
The object of the invention is to provide a fibre container with a dished head which is firmly and efficiently secured to the siding of the container by means of a metal band which is combined with the siding and the head by the method hereinafter described.
The invention further consists in the several features hereinafter' set forth and more particularly defined by claims at the conclusion hereof.
In the drawings Fig. 1 is a vertical sectional view through a container embodying the invention;
y Fig. 2 is a detail sectional view showing the initial position of the parts in the forming apparatus before attaching the head;
Fig. 3 is a detail sectional view showing.
an intermediate position of the parts in the forming apparatus during the attachment of the. head;
Fig. 4 is a detail sectional view show-V of the parts in thev ing the final position vforming apparatus.
The subject-matter of the invention re'- lates to the method and means employed in connecting the head to the siding of the head orcover of the container, and since it is equally applicable for either the cover or the body of the container, the container alone has belenshown in detail for the purpose of explaining the invention.
The siding 5 for the container is of fibre tubing, either of pressed pulp or a number of wrappings of paper or fibre sheets, and
' is generally in the form of cylindrical or conical tubing.
The head 6 is of fibre, consisting'of one or more paper or fibre sheets or laminations, with one or more ofv these laminations bent vat an angle adjacent its edge to form a dished or flanged head.
The metal sheating and clamping band 7 preferably of thin sheet-steel or other suitable sheet-metal, is made up in the form of a band, having an inwardly extending base flange 8 and a slightly curved outeredge 9.
To secure the above named parts together ing and the with the base the siding 5 is placed over an anvil 10, preferably in the form of an expandible chuck, which ,firmly grips the interior of the siding and forms a support for the cover. The siding is clamped between this anvil and an external contractible chuck 11. The dished head 6, with'the flange 12 extending upwardly, is placed in position shown in Fig. 2; with the upper part of the flange extending beyond the edge of the siding, and the band 7 is placed in position on top of said head and within the fiange. A c3- lindrical plunger 13 is then moved down so as to' clamp the head between it and the anvil l() and also clamp the base flange to With the head and the slding clamped lin the position shown in Fig. 1, the plunger 18 is moved downwardly and exerts a pressure against the parts, thereby curling or bending the upper edge of the band and the flange over the upper edge of the siding, as shown in Fig. 3, and fina ing with`the band and flange into a beaded edge and forcing the band and flange laterally into the space 15 to firmly clamp the sidflanged portion of the siding between opposite sides of the band, thereby securely locking the band in position flange 8 of the band firmly held against the. dlsh portion of the head and providing a firm support therefor, partioularly when this head forms the bottom of the container. The lateral displacement of the reinforced beaded edge is important as it provides! an* interlock, and the siding and flange are firmly gripped between the inturned edge 20 of the band and in-turned edge 21 formed by the angle between the base flange 8 and the oonvolute part 22 of the band adjacent thereto..
What I vclaim as my invention is:
In a container, the combination with the siding, of a dished head having a disk porly bending the sidtion and the dish portion fitting within the a portion Aextending above and outwardly head, said dshed portion having a Hange from the outer edge of said base portion over extending beyond the outer side of the disk said flange and the lient-over part of said l0 portion of said head and bent laterally with siding.
5 said siding inwardly over the disk portion In testimony whereof, I aix my signaof saidihead, of a metal band having an ture. annular base portion engaging the head and EDWIN F.\ HULBERT.
