5 7% NN A United States Patent O 3,006,522 CGLLAPSIBLE CONTAINER Edwin L. Arneson, Morris, lll., assignor to Federal Paper Board Company, Inc., Bogota, NJ., a corporation of New York Filed Mar. 11, 1957, Ser. No. 645,177 20 Claims. (Cl. 229-55) The present invention relates generally to an improved form of collapsible container which is provided with new and improved end closure or partition supporting means, the new and improved supporting means capable of being formed integral with the main body portion of the container and/or a cover member from a one-piece blank. Still further, the present invention is directed to a container-forming apparatus for use in erecting the new and improved end closure or partition supporting construction to place the container provided with the same in condition for use.

It is an object of the present invention to provide an improved partition or closure supporting arrangement integrally formed with the body portion of a container from a single blank, the container blank provided with the improved supporting arrangement being capable of formation into a collapsed container in an elicient and time-saving manner, and the collapsed container being readily and easily erectable to provide a strong and long lasting partition or end closure supporting arrangement, the partition or closure being readily and easily insertabie within the container into supporting relation with the new and improved supporting arrangement.

Another object is to provide an end construction for a container which is readily adapted for integral formation with the body portion of the container from a single onepiece blank, the end construction being of uncomplicated design and being readily and inexpensively formed, the end construction still further being readily erectable into operative position and adapted for collapsing to allow the container provided with the same to be folded in a flattened condition for storage and shipment purposes, the end construction still further being provided with sturdily constructed and arranged enclosure supporting means which .are self-bracing and adapted for long-life use.

A further object is to provide a closure or partition supporting arrangement adapted for use with a container, which arrangement incorporates certain features of design which adapts the same for several modified uses with different types of containers and which further allows the same to be continuously reused following collapsing or erection over a long period of time, the supporting arrangement and associated container being inexpensively formed and, in this respect, being disposable if desired.

Still another object is to provide an erecting device particularly adapted for use with the end construction of the present invention, the device being used primarily with a specific form of end construction incorporating the principles of the present invention to erect the same with respect to an associated body container portion when the container is placed into use from a collapsed storing condition.

While the following description deals with the formation of cylindrical containers which are adapted for use in the packaging of many different items and are particularly associated with the merchandising of ice cream and other foodstuffs, it should be understood that the structural features to be described in connection with the end construction of these containers are adapted for use with many different forms of containers. Still further, the type of container to be described is a disposable type formed from flexible cardboard material, and while the description of the present invention is limited to this type of cylindrical container, it is not intended by so limiting the description to limit the scope of the present invention. Consequently, the use of the principles and structural features of the end construction of the present invention may be varied considerably and such variable uses are intended to fall within the scope of the present invention. It should be clear that the containers may be of any desired shape, such as oval or cone-shaped, and if desired, the shapes of the containers including the end construction of the present invention may be such that the containers are capable of being nested in their erected condition.

In FIG. l a blank 34? is illustrated as including a body portion panel 31, the lowermost margin of which is defined by a score line 32 extending continuously across the same. Integrally formed with the lowermost margin by the score line 32 are a plurality of spaced fingers 33 which have integrally formed therewith along margins defined by interrupted score lines 34, a second series of spaced fingers 35. The lowermost margins of the fingers 35 are defined by a continuous score line 36 which defines the area of integral interconnection between the fingers 35 and a continuous band or strip 37. The band 37 defines the lowermost portion of the blank 30 and through the integral interconnection between the ngers 33 and 35, the band 37 maintains the two series of spaced fingers in proper alignment with the body portion panel 31. The spacing between the pairs of fingers 33 and 3S is defined by a plurality of S-shaped apertures 38 which are formed from the excising of material of the blank 30. The apertures 38 define recesses 39 and projections 40 in the side margins of the

fingers

33 and 35. Opposite side margins of each nger are provided with a recess 39 and a projection 40 and, as will be subsequently more clearly described, the S-shaped apertures allowed the side margins of the

fingers

33 and 35 to be brought into abutting engagement upon the erection of a container from the blank 30 and the projections 40 of adjacent pairs of fingers cooperate with one another in overlapping relation to provide the ngers with mutual support.

The body portion panel 31, just inwardly of its opposite or top margin, is provided with a score line 41 extending continuously across the panel 31 and defining a foldable edge band or strip 42. The blank 30 is divided into transverse sections by

score lines

43 and 44 which extend across the entire blank 30 including the

strips

37 and 42 and are interrupted solely by diamond-shaped openings 45 separating adjacent pairs of

fingers

33 and 35 from one another. The openings l45 allow the assembled blank 33 to be folded along the score lines 43 and 44 to place the container formed from the blank 30 in a collapsed condition for storage and shipment purposes. The upper right hand corner of the blank 30 has a cut-out portion 46 formed by removal of an end section of the strip 42 for a purpose to be described. The lower left hand corner of the blank 30, as viewed, is provided with a tab 47 which is a continuation of the strip 37. The fingers 35 are of greater length than the fingers 33 to allow the end construction formed thereby to be assembled as will now be described in connection with FIGS. 3-6.

In FIG. 3 the initial folding operation followed in forming the blank 30 into a cylindrical container 4S shown in FIG. 2 is accomplished by the folding of the end construction, including the

fingers

33 and 35 and band 37, along the score line 32 against the inner surface of the body portion panel 31 which is the bottom surface as viewed in FIG. 3. The second step is shown in FIG. 4 in solid lines and includes the reverse folding of the `fingers 35 and band 37 along the score line 34 and against the inner surfaces of the fingers 33 to allow the band 37 to project outwardly with respect to the end of the body portion panel 31. At this stage in the folding operation a suitable adhesive is applied to the exposed upper surfaces of the

strips

37 and 42 and the same are folded respectively along their

score lines

36 and 41 into the position shown in broken lines. The adhesive `applied to their top surfaces promotes adhesion between opposed surfaces of the

strips

37 and 42 and portions of the outer surface of the body portion panel 31.

As illustrated in FIG. 5, the

fingers

33 and 35 have been folded against one another and form fiat flanges generally designated by the numeral 49 which lie flat against the inner surface of the body portion panel 31 in parallel relation thereto. The right hand section of the body portion panel 31, as viewed, with its associated end construction elements is folded inwardly along the score line 43 into parallel relation with the inner surface of the center portion of the body portion panel 31. Upon the completion of this folding operation a suitable adhesive lis applied to the edge portion 50 of the outer surface of the blank 30 and the left hand section of the blank is folded along the score line 44 into contact therewith. The excised portion 46 allows edge contact between the ends of the strip 42, and the iiap 47 allows the strip 37 to be formed into a continuous outer band. Following the final folding step a collapsed container 48 formed from the blank 30 is completed as illustrated in FIG. 6. The container 48 in its collapsed condition may be conveniently stored or shipped in large quantities at lowcost due to the space-saving features present.

Referring'to FIGS. 7-10, the stages of erection of the collapsed container 48 of FIG. 6 will be described. In FIG. 7 the container 48 is shown after Ibeing moved into a cylindrical shape from its collapsed condition of FIG. 6 and, as particularly illustrated in FIG. 8, the

flanges 49 formed from the

fingers

33 and 35 tend to move radially outwardly from the inner surface of the body portion panel 31 during the shaping operation. The fixing of the band 37 to the outer surface of the bottom edge of the body portion panel 31 fixes the relation of the

fingers

33 and 35 with respect to one another. As previously described, the fingers 35 are of greater length than the fingers 33 and this arrangement allows the body portion panel 31 to be moved into a cylindrical shape without the fingers 35 pulling the fingers 33 downwardly to an extent that the flanges 49 formed thereby are directed outwardly of the bottom portion of the container 48. 'Ihe initial stage of erection of the container 48 places the flanges 49 in an inclined relation with the inner surface of the body portion panel 31, as shown in FIG. 8, and the side margins of the

fingers

33 and 35, defined by the grooves 39 and projections 4f) move toward one another as shown in FIG. 7. Upon completion of the shaping of the body portion panel 31 of the container 4S, and end closure or disk 51 is inserted within the body portion of the container 4S through the opening in the top thereof and moved downwardly into flat and edge-abutting relation with the top surfaces of the fingers 33 as shown in FIGS. 9 and 10. The forcing of the disk 51 downwardly moves the flanges 49 into a substantially fiat condition, as shown in FIG. l0, and further downward movement of the fianges 47 is limited by the bracing action of the fingers 35. In their final operative position, the flanges 49 are brought into edge-abutting relation with one another, as shown in FIG. 9, and the projections 4f) of the

fingers

33 and 35 abut the edges of adjacent grooves 39.

Referring again to the blank 30 of FIG. 1, it will be particularly noted that each adjacent pair of

interconnected fingers

33 and 35 forming flanges 49 have their projections 40 and recesses 39 oppositely positioned. Consequently, the oppositely positioned projections 40 will overlap one another when the container 48 is fully erected. This feature is shown in FIG. 9 wherein a portion of one of the bottom fingers 35 is broken away and its associated top finger 33 positioned thereabove is partly shown with its projection 40 overlapping the projection 4i) of an adjacent bottom finger 35. The overlapping of the projections 4i) provides mutual supporting action between the flanges 49 to further strengthen the end construction. The bringing of adjacent side margins of the

fingers

33 and 35 into abutting relation, as illustrated in FIG. 9, further provides a tightly sealed end construction and prevents lateral displacement of the flanges 49 from their operative position in supporting the disk 51. As further shown in FIG. 9, the diamondshaped openings 45 are substantially closed by abutment between opposite edges of the same when the flanges 49 are in supporting relation with the disk 51. The completely erected container 48 of FIG. 2 is provided with a strongly supported bottom end construction which is completely closed and a suitable lid r closure member of any known type may be applied to the top thereof following the lling of the same with the material to be packaged.

In FIG. ll a slightly modified blank 52 is provided with the same structural features of the blank 30 of FIG. l with but a slight change in dimensions of the fingers forming the bottom disk supporting flanges. As a result of the structural similarities between the elements of the blanks 52 and 3-3, the same reference numerals are used to indicate similar parts thereof. 'Ihe blank 52 is designed to allow the strip 37 to be folded against the inner surface of the body portion panel 31 and to bring this about the fingers 35 are shorter in length than the fingers 33. The reason for this difference in length is clearly illustrated in FIGS. 13 and 14 and a cylindrical container 53 shown in FIG. 12 results from the folding of the blank 52.

Referring particularly to FIGS. 13 and 14, the band 37 and associated

fingers

33 and 35 are folded in such a manner that the band 37 is adhesively fixed to the inner surface of the body portion panel 31 near the bottom edge thereof. As shown particularly in FIG. 13, the erected container 53 prior to the insertion of a bottom disk is provided with the inwardly directed and upwardly inclined flanges 47. As a result of `the placing of the band 37 within the body portion panel 31 of the container 53, the ngers 35 become the fingers which directly contact the disk 51 when the same is inserted in its end closing position as shown in FIG. 14. The fingers 33 become the bracing fingers and are of greater length than their interconnected fingers 35 to brace the same from movement outwardly of the end of the container 53 when weight is applied thereto. Generally speaking, the band 37 and

fingers

33 and 35 may be accordionfolded yabout their interconnecting score lines, adhesive applied to the band 37 and the entire accordion-pleated assembly folded about the score line 32 in parallel relation with the body portion panel 31 and pressed against the same to au extent that the band 37 adheres to the inner surface thereof.

A further slight modification of the end construction of the present invention is shown in FIGS. l5 and 16 wherein a portion of a modied blank 54 is illustrated as being provided with a body portion panel, interconnected pairs of flange-forming fingers and a marginal continuous strip similar to the elements described in connection with the blank 3i) of FIG. l. These elements being exactly the same with respect to their functioning are also identified by the same reference numerals and the modifications residing in the blank 54 deals with the shape of the openings between the flange-forming ngers. The side margins of each of the

fingers

33 and 35 of the blank 54 are inclined inwardly toward their interconnections to denne diamond-shaped openings 55 between each of the interconnected pairs of fingers. As shown in FIG. 16, in looking downwardly through the top opening of a completely assembled and erected container 56 formed from the Iblank 54 and having a portion of the bottom end closure 51 broken away, the adjacent edges 57 of the diamond-shaped openings 55 are brought into a-butment to provide a completely closed ring of flanges 49I in supporting relation with the bot-tom disk 51. While the overlapping functioning of the material of the

fingers

33 and 35 defining the S-shaped openings 38 of the blanks 313 and 52 is preferred, it has been found that the bracing action afforded by the relative positioning of the

fingers

33 and 35 and the positioning of the band 37 with respect to the body portion panel 31 is adequate to properly support the end closure 51 against displacement and prevent end failure in the erected and filled container.

FIG. 17 illustrates a further modified blank 58 from which a cylindrical container may be formed being provided Iwith an end construction of the type described in connection with FIGS, 1-10. The blank 58 is formed from a body portion panel 59 provided just inwardly from its uppermost margin, as viewed, with a continuous score line 60 extending across the blank 58 and defining a top band 61. The lowermost margin of the body portion panel 59 is defined by a continuous score line 62 which in turn ydefines the integral connection of the bottom margin of the body portion panel 59 with a plurality of spaced fingers 63, each of which is integrally joined with a second series of spaced fingers 64, the line of connection being defined by an interrupted score line 65. 'I'he lowermost margins of the fingers 64 opposite their margins of interconnection with the fingers 63 are defined by a continuous score line 66 which in turn defines their points of integral interconnection with a continuous strip or band 67. The spacing of adjacent pairs of fingers `63 and 64 is provided by a plurality of excised portions 68 which are S-shaped and are provided with edges having overlapping projections and adjacent recesses of the type previously described. The blank 58 is subdivided transversely by a plurality of spaced score lines 69 to facilitate the forming of a cylindrical container 70, shown in FIG. 18, which has a large diameter.

The ,container 70 of FIG. 18 is formed from the blank 58 by reversely folding the band 67 about the score line 66 and against the outer surfaces of the

fingers

63 and 64 as shown in FIG. 21. The blank 58 is then folded and glued to form a collapsed container 70 (not shown) which is erectable as Will be described. Adhesive is now applied to a surface of the band 67 to fix the same with respect to the outer surface of the body portion panel 59. To properly form the blank 58 into a collapsed container 70 the body portion panel 59 and strip 67 are provided with

flaps

71 and 72 respectively which overlap the opposite ends of the panel and band for iixing thereto by the use of adhesive as previously described in connection with the blank of FIG. 1.

FIGS. 19-21 illustrate the difference in functioning of certain elements of the blank 58 when the same is formed into the container 7i). The fingers 64 are of greater length than the lingers 63 to allow the latter to be moved into a substantially horizontal plane at right angles with the vertical side walls dened 'by the body portion panel 59. The fingers 64 are inclined upwardly in an inwardly direction to brace the fingers 63 in forming a plurality of inwardly directed edge-abutting iianges 73 of the type previously described. An end closure 74 is then placed in supporting engagement with the top surface of the fingers 63 and the container 7) is completely formed. In bringing this about, the positioning of the band 67 must be iixed with respect to the outer surface of the body portion panel 59 to maintain the flanges 73 in their edgeabutting and disk-supporting position. 'Ille body portion panel 59 is relatively short in height Whereas the band -67 is relatively wide, and in erecting the container 70 from a collapsed condition the band 67 is slidingly moved along the outer surface of the body portion panel 59 toward the upper end thereof. The extent of upward movement of the band 67 is limited to place the anges 73 in their operative positions by edge-abutment between the top marginal edge of the band 67 with the bottom marginal edge of the outwardly and downwardly folded strip 61. Abutment between these edges is shown in FIG. 20 yand the anges 73 at this final stage of the erection of the container 70 extend inwardly in proper supporting Yrelation with the end closure 74 and in partially overlapping and edge-abutting relation with adjacent anges 73.

As shown in FIG. 21, in forming the container 70 from the blank 58 into collapsed condition it is necessary merely to reversely fold the band 67 against the outer surfaces of `the

fingers

63 and 64 and the body portion panel 59. The width of the band 67 may be sufficient to overlap a portion of lthe panel 59 extending inwardly beyond the score line 62, but it has been -found that in erecting the carton 70 from its collapsed form the band 67 will be capable of sliding upwardly along the outer surface of the body portion panel 59 even though its uppermost marginal edge is positioned adjacent or below the score line 62.

Still ya further modification of end construction for collapsible containers is shown in FIGS. 22-25. Referring in particular to FIG. 22, a blank 75 is illustrated as having a body portion panel 76 integrally formed with identical end constructions along each of the opposite end margins thereof. Each of these opposite margins is partially defined by interrupted score lines 77 which hingedly attach ngers 78 to the body portion panel 76. Fingers 79 of greater length than the iingers 78 are integrally connected to margins of the lingers 78 by interrupted score lines 80. Continuous score lines 81 define continuous marginal strips or bands 82 and the pairs of attached

fingers

78 and 79 are spaced from one another -by S-shaped excised portions 83, the

edges of which deiine projections and recesses of the type previously described. The blank 75 is transversely divided into relative foldable sections by a plurality of spaced score lines S4, and in folding the blank 75 to form a container in its collapsed form, the procedure described in connection with the blank 58 of FIG. 17 is followed and the elements of the end constructions in ltheir collapsed condition are similar to that 'illustrated in FIG. 21.

The blank 75 differs from the blank 58 in that similar end constructions are provided for both ends of the container 85 formed therefrom. The blank 75 is particularly adapted for use in `the formation of tall containers wherein the bands 82 are positioned about outer end surfaces of the body portion panel 76 in slidable relation therewith and are not xed thereto by the use of adhesive or any other suitable means. To allow the bands 82 to be positioned about the outer surface of the body portion panel 76, the fingers 79 are of greater length than the fingers 78 to brace the latter in providing a plurality of edge-abutting flanges 86 similar to the anges 73 previously described. The blank 75 is further provided with a tab-

like portions

87 and 88 integrally formed with the body portion panel 76 and bands 82 respectively for adhesive interconnection with the opposite margins of the blank 75 during the formation of a collapsed container 85.

To limit the slidable movement of the bands 82 toward the center of the body portion panel 76 upon the erection of the container 85 and thereby assuring proper positioning of the iianges 86, abutment means in the form o-f lugs or projections 89 are excised from the materialY of the lingers 78 adjacent their interconnection with the marginal portions of the body portion panel 76. The lugs S9 are retained in coplanar relation with the body portion panel 76 when the blank 75 is formed into a collapsed container 85 and the same is erected as shown in FIG. 24. rIhe outermost edges of these lugs abut the inner surfaces of the fingers 79 near the score lines 81 when the

fingers

78 and 79 are properly positioned :in supporting relation with a bottom end closure disk and in coniining relation with a top end closure disk 91 as shown in FIG. 24. The extent to which the lugs 89 project outwardly from the score lines 77 controls the extent to which the bands 82 move toward the center of the body portion panel 76 in sliding engagement with the outer surface thereof thereby controlling the desired positioning of the flanges 86.

As previously described, the bands 82 are positioned about the outer surfaces of the lingers 78 and 79 when the container 85 is in its collapsed condition. In erecting the container 85 the bottom band 82 is moved inwardly toward the center of the body portion panel 76 as shown in FIG. 23 and the

fingers

78 and 79 move relative to one another to ultimately form the flanges 86 directed radially inwardly toward the center of the container 85. Upon continued movement of the bottom band 82 toward the center of the body portion panel 76, the lugs 89 ultimately contact the fingers 79 near their integral connection with the band 82 as defined by the score line 81. The bottom end closure 90 is then placed within the interior of the container 85 in resting engagement with the top surfaces of the fingers 78. The container may be filled with any type of material and a top end closure 91 is then placed within the container to seal the top end thereof and the top end construction is manipulated in the same manner as described in connection with the bottom end construction shown in FIG. 23 to iix the top end closure 91 within the container as shown in FIG. 24.

The use of end constructions of the type described at each end of the container 85 is particularly desirable where the material placed within the container is of substantial weight. For example, containers of this nature are particularly adapted for the packaging of roong tar or wax and regardless of which end supports the total weight of the contents of the container, the anges 86 are capable of preventing failure of the container S which would result in loss of contents or exposure of the same. In gaining access into the interior of the container 85 it is necessary merely to retract one of the bands 82 by sliding it away from the center of the body portion panel 76 thereby bringing the

ngers

73 and 79 into substantially coplanar relation with the body portion panel 76. At this point the

end closure

90 or 91 may lbe removed and the material within the container 85 is made accessible.

ln FIG. 25 the same type of end construction previously described in connection with the blank 75 of FIG. 22 is illustrated as being utilized with a container 92 at the bottom end thereof. The top end of the container 92 is provided with an outwardly and downwardly turned band 93 adhesively secured to the outer surface of the body portion panel 76 and adapted to receive thereabout a conventional form of top end closure or lid. From a description of the elements shown in FIGS. 22- 24, it should be clear that the end construction is fully adapted for use at either one or both ends of a container depending upont he type of end closure support desired.

FIGS. 26-29 illustrate a device 94 for use in erecting the end construction described in connection With FIGS. 22-25. In FIGS. 26 and 27 the device 94 is illustrated as being formed from separate

semi-circular member

95 and 96 which are connected by a hinge 97 to allow the member to be moved away from one another to receive therebetween a container carrying an end construction for erection. The member 95 carries a pair of ears 93 which receive therebetween a locking rod 99 hinged at one end to the member 96. The end of the locking rod 99 received within the ears 98 is provided with a nut 100 which holds the

members

95 and 96 in their operative relation while the container positioned therewithin is having its end construction erected.

The manner in which a container 92 is placed into completely erected condition by use of the erecting device 94 is illustrated in FIGS. 28 and 29. The

members

95 and 96 along their inner vertical surfaces are provided with horizontally aligned, radially inwardly directed arcuate flanges 102 which define radially and downwardly opening grooves 103 for receiving therewithin the strip 82 of the container 92. 'Ihe strip 82 is positioned within the grooves 103 by closing the

members

95 and 96 with respect to one another and locking the same by use of the rod 99 and ears 98. The innermost surfaces of the flanges 102 are arcuate and incline outwardly in an upwardly direction to provide a camming surface to buckle the

ngers

78 and 79 about their interconnecting score lines 80 inwardly and urge the lugs 89 inwardly when the body portion panel 76 is moved downwardly into the interior of the device 94. As shown in FIG. 28, the body portion panel 76 is in the process of being moved downwardly and the

fingers

78 and 79 are moving into their radial relation with the body portion panel 76 to form the flanges 86. The lugs 89 are being cammed inwardly by the inwardly sloping surfaces 104 to clear the upper edge of the band 82 received within the grooves 103. As shown in FIG. 29, the lugs 89 have cleared the top edge of the band 82 to allow the same to be brought into abutting relation with the top surface of the fingers 79 near their score lines 81 interconnecting the same with the band 82.

Upon completion of the operation as shown in FIG. 29, the anges 86 are properly positioned within the container 92 to receive in supported relation therewith an end closure disk. The completely erected container 92 is removed from the erecting device 94 by releasing the locking bar 99 and moving the

members

95 and 96 away from one another about their hinge connection 97.

The foldable flange type closure disk supporting construction described in connection with the drawings with emphasis being placed on the dilerent modified forms of constructions utilizing the principles of the present invention can readily be incorporated in the formation of a removable cover member for use with any known type of container and particularly for use with the type of containers previously described. In FIG. 30 a one-piece cover member blank is illustrated as being formed from a band or strip 106 integrally attached along one of its margins to a plurality of fingers 107 which are foldable relative thereto along periodically interrupted score lines 108. The margins of the lingers 107 opposite their attachment to the band 106 are integrally formed with cooperating lingers 109 by score lines 110. The opposite margins of the fingers 109 are in turn integrally and foldably formed with a strip or band 111 to thus complete the main elements of the blank 105.

The foldable finger construction is similar to that described in FIG. 22 in connection with the blank 75 and the opposite side margins of the

fingers

107 and 109 are provided with cooperative projections 112 and recesses 113 to provide a self-supporting flange arrangement when the blank 105 is erected. Similarly, the margin of the band 106 interconnected with the fingers 107 is provided with spaced flanges or tabs 114 which are excised from the material of the lingers 107. Suitable end tabs 115 are provided at the ends of the bands 106 and 111 for gluing purposes as previously described for the forming of the blank 105 into a collapsed cover member or cover member rim.

The collapsed cover member rim is formed from the blank 105 by folding the blank in half along its approximate center line defined by the score lines 110 thus forming flanges 116 illustrated in FIG. 31 which are folded inwardly into edge or side abutting relation. A series of transverse score lines 117 allow the blank 105 to be readily folded, glued and erected in a rim-like shape with the flanges directed inwardly as illustrated in FIG. 31. The band 111 is received about the outer surface of the band or cover member body portion 106 in sliding relation therewith as a result of the fingers 109 being of greater length than the fingers 107. In erecting the cover member rim of FIG. 3l the band 111 and 106 are slidaoly moved relative to one another in opposite directions until the ends of the tabs or flanges 114 abut the inner surfaces of the fingers 109. The cover member rim formed from the blank 105 is readily erected for use from a collapsed condition in the same manner as described in connection with the end constructions of the container formed from the blank 75 of FIG. 22.

FIG. 32 illustrates the use of the cover member rim formed from the blank 105 in xing a closure disk 118 in sealing engagement with the top edge of a container 119. The container 119 is of the same construction as the container 92 of FIG. 25 and, as a result, like reference numerals are used to identify the same structural elements. Upon complete erection of the cover member rim from the blank 105, the closure disk 118 may be readily received therein in supported engagement with the outermost surfaces of the fingers 107 and thus held in engagement with the top edge of the container Wall 76. The completely assembled cover member is readily received about the outer surface of the container 119 and may be readily removed therefrom, dismantled and refolded into its collapsed condition for storage prior to reuse if such is desired. The type of cover member described in connection with FIGS. 30-32 may be readily set up or erected similarly to the containers 93 by use of the apparatus illustrated and described in FIGS. 26-29. While a cover member has been described as being formed from a flange arrangement of the type illustrated in FIG. 22, it should be apparent that the flange arrangements of FIGS. 1, 1l, 15 and 17 may also be used.

Still a further modified form of disk supporting flange structure is shown in FIGS. 33-35. In first considering FIG. 33, an end structure of a blank 120 is illustrated as including a body portion panel 121 having integrally attached thereto a plurality of fingers 122. The margins of the fingers 122 opposite their attachment to the body portion 121 are integrally formed with cooperating fingers 123 by score lines 124. The opposite margins of the lingers 123 are in turn integrally and foldably formed with a marginal strip or band 125. The joined

fingers

122 and 123 cooperate to define closure disk supporting flanges 126 which in their erected condition, as shown in FIGS. 34 and 35, have the side margins thereof telescopically related with adjacent side margins of adjacent anges.

To provide for interleaving or telescopically joining adjacent flanges 126, each of the joined finger structures of the blank 12) is provided with an outwardly inclined or projecting side margin 127 and an inwardly recessed opposite side margin 12S. Thus, each linger construction defining a vliauge 126 is oftset centrally thereof at the score line 124 in a direction toward the right as viewed in FIG. 33. The central offsetting of each ringer construction may be reversed, i.e. to the left as viewed in FIG. 33, as long as the direction of offset is consistent in any one blank. Upon forming the flanges 126I in the same manner as previously described in connection with the several modifications of the present invention, the projecting side margins'127 of cooperating

fingers

122 and 123 form a projection 129' Which is telescopically received within an adjacent flange 126, the recessed side margins 128 of the

fingers

122 and 123 of the adjacent ange overlapping a substantial marginal portion of the projection 129. Thus, with each flange 126 the project- 'ing side margins 127 of the same are telescopically received in an adjacent fiange while the recessed side margins telescopically receive another flange to define an alternating telescopic and interleaved structure.

In all other structural respects the end construction of the blank 12% is the same as those previously described which utilize spaced lianges or tabs 13d excised from the material of the fingers 122. Suitable end tabs 131 are provided at the ends of the body portion 121 and band 125 for gluing purposes in the manner previously described when the blank 12d is formed into a cylindrical end construction. As shown in FIG. 34, a closure disk 132 is supported by the inner surfaces of the fianges 126 and the interleaving structural arrangement of these flanges provides increased support for the closure disk 132 thus allowing the container which includes this particular type of end construction to support and hold material of greater weight without rupturing.

The ange end construction of the blank 121i can be readily used in the formation of a bottom disk supporting structure in a container or a top disk supporting structure in a removable cover member for a container. The length of the body portion 121 Will control this particular use and, as previously described, the end construction of the blank 120 is set up in the same manner as discussed above. Upon setting up this particular end constructiongthe band 125 is received about the outer surface of the body portion 121 with the projecting tabs 130 abutting the outer end margins of the fingers 123 in close proximity to the continuous score line 133 integrally joining the lingers with the band 125 The above description illustrates different end constructions or closure disk supporting arrangements of uncomplicated design each of which is readily adapted for forming from a one-piece blank in integral connection with the main body'portion of a collapsible container and collapsible cover member of the throw-away type. The forming of the one-piece blank including the end construction of the present invention may be readily accomplished by the use of uncomplicated cutting dies and the folding and xingof the elements of the blank to provide a collapsed container or cover member is a simple process which does not require the use of expensive apparatus or skilled personnel. Many different variations may be utilized in the end construction of the present invenuon as illustrated by the various modifications described above and the principles utilized in the design of the end construction are readily adapted for variation to meet different requirements in the formation of collapsible containers. The elements of the end constructions are protected against damage during storage or shipment when the container or cover member is in its collapsed form by reason of the flanges formed from the relatively foldable fingers being received Within the interior of the collapsed body portion of the container or cover member. Upon completion of the first stage of erecting the container or cover member from its collapsed condition, the iianges of the end construction move outwardly away from the inner surface of the body portion in position to receive in supporting relation an end closure disk inserted through the top of the container or bottom of the cover member and moved into contact with the flanges. Following use of the container or cover member, in the event that disposal of the same is undesired, the end closure disk may be readily removed from the interior of the body portion and the container or cover member may be returned to its collapsed condition with the flanges folded in substantially parallel relation with the body portion panel inwardly of the end thereof and protected by the same.

1n addition to the foregoing important advantages residing in the use of the end constructions of the present invention, it should be particularly noted that the flanges forming the bottom of a container are closely related to the horizontal and thus positioned in close proximity to a supporting surface when the container is erected and being filled or used. Where the container is used in packaging ice cream, the use of a scoop or the like to remove the ice cream from the bottom portion of the container resulting in the scraping of the bottom closure disk by the scoop and the application of substantial pressure against the bottom closure disk does not cause the closure disk to rupture as the flanges of the end construction are in close proximity to the solid supporting surface. Still further, the flanges extend radially inwardly a substantial distance so as to provide the bottom closure disk with appreciable support inwardly of the periphery thereof.

This application is a continuation-in-part of my copending application, Serial No. 620,286, tiled November 5, 1956, now abandoned, Which is a continuation-in-part of my copending application, Serial No. 586,999, filed May 24, 1956, also now abandoned.

Obviously many modifications and variations of the invention as hereinbefore set forth may be made without departing from the spirit and scope thereof, and therefore only such limitations should be imposed as are indicated in the appended claims.
