Fig. 'l is a plan view of a modified form of the 40 container in which the bottom member is integrally secured to the body portion;
,- Fig. 8 is a fragmentary sectional view taken Containers of this type have replaced metallicv containers to a considerable extent inthe ice cream industry. As will be recognized, important factors i'n the success of this type of container are the ease with which the bottom may be secured to the body portion of the container and the effectiveness of the resulting interlocking.
The container of the present invention may be erected or set up from collapsed condition by hand and in such condition is suiiiciently sturdy to withstand hard use. The improved container is constructed by providing a fibrous body portion of the usual type with interlocking openings adjacent its end portion and producing a suitable interlock between this body portion and a bottom member having a series of fingers along its periphery. As shown in the drawings, one set of the n'gers extends upwardly adjacent the inner wall of the body portion and the other set of the fingers is interlocked with the body portion. An inner bottom member is pressed into engagement with the first mentioned set of tongue members and it is preferred to employ .an inner body portion to add further strength to the assembled container. A
The embodiment of the invention shown in Fig. 1 consists of a body portion I0 constructed of a blank cut, scored and folded as shown in Fig. 3 to provide a locking strip II on each end of the blank, vertical score lines I2, and a series o'f bottom interlocking slots I3 adjacent the lower end of the container. 'Ihe body portion'is produced by suitably securing together the opposite attaching aps Il so that the body portion assumes a tubular form which may be collapsed by'being flattened along diametrically opposite score lines I2. The bottom member is formed is provided with a first series of tongues I5 which are adapted to lie adjacent the inner wail of the body portion and a second set of tongues I6 which may be interlocked with the openings Il of the body portion. The diameter of the disk I4 is substantially the same as the inside diameter of the body portion. Tongues I5 are scored at their point of jointure to the disk Il, and thc tongues IB may be scored additionally at a slightly extended distance from the center of the disk.
It will be noted that the tongues- I6 in the embodiment shown in Figs. 1, 2 and 4 are of less length than the tongues I5. '1111s difference in length may be used to advantage in erecting the container. That is, the body portion may be distended into tubular formation and the disk I4 may be pressed downwardly therein from the top 'of a disk Il, such as is shown in Fig. 2. The disk of the body portion. This downward pressure causes both sets of tongues to fold upwardly. The disk I4 may be progressively pressed downwardly in the body portion of the container until 5 the shorter tongues I6 escape from the lower edge of the body portion, As the tongues I5 are longer than the tongues I6, the former will still be retained within the body portion. The resilience of tongues I6 will cause them to move outwardly l from within the body portion and the disk then may be pressed upwardly in the body portion l until the bases of tongues I6 engage the lower edge of the body portion. Tongues IB then may be interlocked in openings I3 in the customary 15 manner with interlocking elements of this type.
That is, adjacent tongues I6 may be pressed together in overlapping relation and then inserted in the openings I3. Upon spreading the tongues apart an interlock is effected. 20 An inner body member I1, which may be formed of a blank similar to that shown in Fig. 3, but having a series of tongues I8, as shown in Fig. 8, along its lower edge, then may be inserted within the body portion and the fingers 25 or tongues I8 may be rotated inwardly into the position shown in Figs. 5, 6 and 8. 'I'hat is, the inner body member is inserted within the outer body member with the tongues I8 resting adjacent the disk I4. An inner bottom member I9 30 then may be inserted within the inner body portion and pressed downwardly against the tongues I8. Preferably, this inner bottom member is slightly oversized so as to frictionally engage the tongues I between the inner and outer 35 body portions. This frictional engagement is increased when the container is lled with a commodity such as frozen ice cream.
In the modied form of the invention shown in Fig. 6 the tongue members I6 also lie along the 40 inner surface of the body portion and extend outwardly through the openings I3. In this embodiment the lower portions of tongues I6 are protected by the lower edge of the body portion.
In the embodiment of the invention shown in 45 Figs. 'l to 11, the tongue members I5 are of substantially the same length as the tongue members I6, and one pair of the tongue members IB is replaced by an integral connection of the disk I l to the body member I0 along a score line 20. 50 The disk Il may be rotated about score line 20 into superimposed relation with respect to the body portion Ill, and the securing flaps II then may be stapled together. The container may be erected merely by rotating the disk I4 down- 55 wardly into substantiallyhorizontal position. In such cases, the ngers I5 are interlocked with the openings I3 on the body portion from the inner side of the latter, as shown in Fig. 6. I! the disk I4 is not secured within thebody portion as 60 described, the blank may be formed into tubular shape by securing naps I I together and the container may be erected by rotating fingers I5 inwardly to such an extent that they will protrude upwardly into the body portion when the disk Il is rotated into horizontal position. The ngers I6 are interlocked with openings I3 from the outside of the body portion, as shown in Figs. 8 and 9. An inner bottom member I1 having tongues I8 along its lower edge may be inserted within the outer body portion as shown in Fig. 8 and an oversized disk or inner bottom member I8 may be inserted to interlock the elements together. Where the outer bottom member Il is integrally attached to the body portion I0, as shown in Fig. 10, the ngers I5 adjacent the point of attachment are shortened.
A particular advantage oI the structure described herein resides in the bracing eil'ect produced by suspending the bottom member directly to the vertical walls of the body portion. The interlocking eiIect of this arrangement is increased by lling the container with a commodity, and, at the same time, there is produced the frictional engagement of the ngers I5 with the body portion. These two types of interlock combine to produce a sturdy and economical container.
Various changes and modifications of the strucportion through said openings, an inner body member having fingers extending adjacent said closure member, and an inner disk pressed into engagement with said inner body member to hold said rst named ngers in frictional engagement with said body portion.
2. A container of the type described, comprising a tubular body portion having openings adjacent one o1' its ends, a closure member of substantially the same diameter as said body portion, a series of relatively long ngers and a series of relatively short ngers on said closure member, one of said series of vlingers lying adjacent the inside of said body portion and the other of said series of fingers ntting adjacent the exterior of said body portion in interlocker relation with said openings, and an inner disk pressing said fingers into engagement with the body portion of said container.
