9 Claims.
This invention relates to improvements in containers, such as those formed largely of paper, fibreboard or the like, and its purpose is to provide an improved form of construction for reenforcing the annular wall of the container and. uniting this wall with the bottom or end wall.
' Containers of this type are adapted to be filled with ice cream, candy, chemicals, or other commodities and are shipped in large numbers from the place of manufacture to the user who fills them with the commodity to be transported therein. It is desirable to provide a construction including an end wall and other parts which may be shipped in compact form by the manufacturer 1 and then readily assembled by the user preliminary to filling them. The principal object of the present invention is, therefore, to provide an improved container comprising an annular wall and a bottom or end wall which are held in proper 20 relation to each other and reenforced by an annular metallic rim having one part adapted to support the bottom or end wall and another part interlocking with the annular wall to hold the parts in assembled relation. A further object of 25 the invention is to provide an improved container having an annular wall in combination with an annular metallic rim provided with an inwardly 30 wall spreads the lower part of the annular wall into interlocking engagement with projections carried by the rim. A further object of the invention is to provide a container having an annular wall in combination with an annular 35 metallic rim provided with an upwardly and inwardly extending transversely corrugated flange adaptedto support a bottom wall and having inwardly extending projections adapted to penetrate the annular wall when this wall is spread I 40 by the insertionv of the bottom wall. Still'another object of the invention is to provide an improved method of forming a container which consists in providing an annular, non-metallic wall and a circular non-metallic bottom wall,. then placing over the end of the annular wall an annular metallic rim having projections on its inner side opposite the lower end of the lower wall and having an inwardly and upwardly extending flange located on the inner side of the annular wall, and then .placing said bottom wall within said annular wall to spread the annular wall into interlocking engagement with said projections on the rim. Other objects relate to various features of the improved method and to various details of extending flange adapted to support a bottom or end wall which, when inserted within the annular construction of the improved container which will appear more fully hereinafter. v
The nature'of the invention will be understood from the following specification taken with the accompanying drawings in which two examples 5 of the improved container are illustrated.
In the drawings,- i Figure 1 shows a perspective view of the im proved container with a portion thereof broken away to illustrate the bottom wall and the sur l0 rounding metallic rim.
Fig. 2 is a perspective view of a portion of a metal frame or strip from which the metallic rim is formed.
Fig. 3 is a perspective view of the metal strip shown in Fig. 2' after it has been operated upon to efiect the transverse corrugation of an edge portion thereof.
Fig. 4 shows a perspective view of the strip or band illustrated in Fig. 3 after the corrugated portion has been bent transversely to form an inclined flange. I
Fig. 5 is a perspective view of the band'illustrated in Fig. 4 after it has been further operated upon to form inwardly extendingmrojections. thus providing the completed rim.
Fig. 6 is a vertical section through the improved container showing the preliminary stages of its assembly, showing the annular wall engaging the metallic rim and the bottom wall in readiness to be inserted within the annular wall.
Fig. 7 is a vertical section similar to that of Fig. 6 showing the relative positions of the parts after the bottom wall has been inserted within the annular wall to expand the lower portion of the annular wall into' engagement with the projections carried by the rim.
.Fig. 8 is an enlarged vertical section taken through the lower part of the annular wall and the contacting metallic rim showing the relative 40 positions of the parts as illustrated in Fig. 6, prior to the insertion of the bottom wall.
Fig. 9 shows an enlarged vertical section through the lower part of the annular wall and the rim, together with a portion of the bottom wall, illustrating the relative positions of the parts after the bottom wall has beein inserted to expand the annular wall into engagement with the projections on the rim.
Fig. 10 shows a vertical section similar to that 01 Fig. 6 through a modified form of construction in which the lower end of the annular wall is pleated or corrugated longitudinally; and
Fig. 11 is an enlarged vertical section through the form of construction illustrated in Fig. 10,
illustrating the relative positions of the parts after the bottom wall has been inserted, portions of the container being broken away.
As illustrated in the drawings, the improved container l5, comprises an annular non-metallic wall It formed of paper flbreboard or the like which is made from a sheet of appropriate size having its ends overlapped and then secured together by glue or other fastening means. This annular'wall is adapted to be collapsed tor purposes oi. shipment and is employed in conjunction with a circular non-metallic bottom or end wall i8 which may be formed of similar material, but which is of heavier construction. These walls are held in assembled relation by means of an annular metallic rim 20 which hasa cylindrical body portion 2|) surrounding the lower end of the annular wall and which is' provided at its lower edge with an upwardly and inwardly inclined flange 20 which is transversely corrugated as shown at 20 and which is adapted to engage and support the bottom wall I8 when the bottom wall is inserted within the annular wall. The cylindrical body portion 2|) of the metallic rim is provided with a series of inwardly extending punched projections 20 which are adapted to extend into the material of the annular wall It when this wall is expanded slightly by the insertion of the bottom wall I8, thus securing the rim 20 firmly in place on the lower end of the annular wall.
The rim 20 is adapted to be formed from a strip 2| of flexible steel or the like which has suflicient ductility to permit it to be bent into, andto retain, any desired form. The preliminary operation of forming the rim 20 consists in operating upon the strip 2| to effect the transverse corrugation of a lateral portion thereof as shown in Fig. 3. these being the corrugations 20 which appear in the finished rim. This transversely corrugated part is then bent transversely and upwardly inclined as shown in Fig. 4 to provide the flange 20 and the body portion of the 'Referring to Figs. 6 and 8 of the drawings, it.
will be observed that when the lower end "of the annular wall It is initially placed within the body portion of the metallic rim 20, the inwardly extending punched projections 2ll have a slight engagement with the annular wall, but do not interfere with the insertion of this wall within the rim. This illustrates the initial stage or the assembly of the parts of the container and when .the annular wall has been placed within the metallic rim as shown in Fig. 8, the bottom wall I8 is inserted as shown in Figs. '7 and 9. This bottom wall is of such size that it causes the lower end of the annular wall to expand slightly as the bottom wall reaches its seat upon the upwardly inclined corrugated flange 20 of the rim, and this causes the annular wall to be projected outwardly so that the projections 2i! on the rim penetrate the annular wall, thus securing the rim in fixed engagement with the annularwall and providing a firm support for the bottom wall l8. The annular wall It may have a normal out,-
side diameter of the same dimensions as the inside diameter of the body portion of the rim 2. and this annular wall may be scored longitudinally by the projections 2|). when the rim is placed over the lower end of the annular wall, but
when the bottom wall I8 is subsequently inserted, it is found that the projections 20' are caused to penetrate the annular wall further so that the removal of the rim is then eflectively prevented. I
In order to permit the'ready expansion o1' the lower portion of the annular wall into engagement with the projections which are carried by the annular metallic rim, it may be desirable to eflectthe longitudinal corrugation or pleating of the annular wallof. the'container and this modification is illustrated in Figs. and 11. In this form of construction. the annular wall 23 is formed of paper, fibreboard, or the like, as in the embodiment first described, and it is adapted to have inserted within it a bottom wall 24, preferably of similar material, which serves the function of expanding the lower portion of the wall 23 into interlocking engagement with the annular metallic rim 25. This metallic'rim is identical in construction with the rim previously described, being provided with a bodyportion 25* of cylindrical form, from which there extends upwardly and inwardly a flange 25 which is transversely corrugated as shown at 25 and which is adapted to support the bottom wall 24. The body portion 25 of the rim 25 is provided with in- 'wardly extending punched projections 25 which are adapted to engage the lower end of the annular wall when this wall is extended by the insertion of the bottom wall. To facilitate the insertion of the bottom wall and the resulting expansion of the annular wall,--the lower portion of the annular wall is longitudinally corrugated as shown at 23, thus providing a series of parallel grooves or indentations 23' which permit the lower end of the 'annular wall to be initially contracted as shown in Fig. 10 so that it may be readily inserted within the metallic rim 25.
: When it has been thus inserted, the bottom wall 24 is put in place on the flange 25', thus expanding the corrugated portion of the annular wall intointerlocklng engagement with the penetrating projections 25, as shown in Fig. 11.
Although certain embodiments oi. the invention have been shown and described by way of illustration, it will be understood that it may be constructed in various other embodiments and that the improved method may be practiced in various ways coming within the scope of the appended claims; The improvements of the present invention have been described in connection with the construction of the bottom of a container, but many of these features may be embodied in rims for the tops of containers and associated parts and the claims are to be construed accordingly.
