l`1o claims. (ci. 22a-5.5)

This invention relates to containers, and more particularly to an improved container which can be shipped to and stored by the user in collapsed knockdown condition and thereafter set up by 5 the user as needed.

In the packaging of relatively bulky products, substantial savings can be eiected if the container in which 'the products are to be packed can be shipped and stored in knockdown or collapsed l condition and which are so constructed as to permit rapid and .positive assembly into containerforming position b y the user. Such containers should preferably be so constructed that a minimum of hand operations is required to assemble l the same and which preferably can be assembled into a strong and rigid structure by the interlocking of the parts and without the use of glue, staples or other securing means.

In accordance with thepresent invention, a

body member is provided which may be formed from a ilat blank'of paperboard material suitably secured together in tubular" form, or which may `be made into tubular form by forming a paperboard strip on a mandrel and thereafter scoring the tubular member to permit substantially iiat collapse thereof. 'I'he end closure may y comprise a at disc or blank formed of relativelystili.' paperboard or other material, which'is inserted into oneend of the body member and arranged to interlock with an inturned rim portion provided on the body member. l The inturned rim portion is divided into predetermined sections by longitudinally extending scores. certain o! the sections being arranged tobulge inwardly-so that the free end portions of the sections provide a shoulder upon which the end closure is adapted to seat. `'I'he shape and extent of the inwardly bulging sections can be determined by providing the bulging sections with suitable score lines 40 which will cause the bulge to attain a predetermined shape. Certain of the sections may be provided with tab portions against which the periphery of the end closure or end piece is adapted to abut to maintain the rim. portion and its associated inwardly bulging sections in rigid end closure-.supporting position. 'Ihe tab portions can be turned inwardly to overlie the end closure and an insert disc positioned'within the tubular body portion tooverlie the tab portions providing 50 a smooth and finished interior for the container.

As thus arranged the tab portions are compressed between the end closure or end piece and the insert disc with the end piece adequately supported upon the inwardly buiging shoulders. providing a container which is unusually rilid and strong in I and inserting the insert disc through thebody or containing portion of the container. My iml0 proved container is admirably adapted for the packaging of numerous products, either semiliquid, powdered, or granular in form, as well as other articles and merchandise. When assembled the ends of the container are provided with a rim l5 portion which permits free circulation of air under and between the stacked containers and protects the contents from damage due to moisture and other conditions during storage.

An object of this invention is to provide an im- 20 proved knockdown container which is strong and durable in construction, which can be shipped in collapsed flat condition, and easily and quickly set up by the user as needed.

Another object of this invention is to provide 25 a container having an improved end closure construction whereby the bottom or top-forming pieces may be assembled and interlocked to the body member without the use of glue, staples,for v other securing means to hold the parts assembled. 30

Other objects of this invention will become ap-v parent as the disclosure proceeds.

In order that a clearer understanding of my invention may be had, attention is hereby directed to the accompanying drawings, forming a 35 part of this application and illustrating certain possible embodiments of my invention.

Similar reference characters denote similar parts throughout the drawings and specification.

The structural members forming my improved container include a body member A, an end closure B, and an insert disc C. The end closure B and the insert C may be used to form either a bottom closure or a top closure, or both, as desired. The body member A, end closure B and .insert C may be formed of paperboard or fiberboard material,` and may be shipped and stored in fiat collapsed-condition and assembled into a container by the user as needed. The body member A may be formed from a blank of relatively tough, iiexible berboard material having a bodyforming portion I. A flap 2 may be provided along one vertical edge of the body portion l `which may be secured by adhesive, staples, or

other securing means, to the other vertical edge of the body portion. The body member may be formed of generally circular shape by providing a series of spaced longitudinally extending score lines 3 transversing the body portion I thereof, which score lines also permit substantially .dat

collapse of the body member when assembled into tubular. form.

Means are provided at the lower end of the body member to support and secure the bottom closure flxedly assembled to the body member. Similar means may also be'provided at the upper end of the body member to secure the cover 4closure in xed assembled position to the body member.

The end closure securing means may be formed by providing an internal rim portion a defined by a score line 4 extending transversely along the bottom of the body blank, as shown' in Fig. 1. The rim portion is adapted to be turned inwardly to seat against the inside face of the body portion I. The inturned rim portion a is divided into a plurality of segments by vertically extending score lines-1. Certain of the segments 5 are provided with tab or tongue portion 6 which may be hinged to the segment 5 along the transverse score lines I2. Other segments are provided with inclined score lines II defining a triangular shaped portion I therebetween. Wing portions 8 and 9, at opposite sides of the 'triangular portion I0, are defined by the score lines I sociated may also be spaced any distance apart desired or they may be arranged to alternate with the sections having the triangular forming portions IIl, as illustratedin Figs. 1, 4 and 5. To facilitate manufacture, the score lines 1 in the rim portion may be formed as a continuation of the score lines 3 in the body portion I.

, It will be noted that when the rim-forming portion a of the body member is turned inwardly so as to lie against the inside face of the body portion I, the rim portion will lie substantially flat against the blank when it extends in the flat form shown lin Fig. 4. When, however, the body portion is shaped into generally tubular form, as shown in Fig. 5, it will be appreciated that the rim portion must compact itself into a smaller circumferential space than the body portion I, positioned outside of the rim portion. Consequently, there is a tendency for the rim portion to Wrinkle or buckle. This tendency is taken advantage of in the present invention to provide a strong and rigid means to support the end closure.

When the rim portion is formed as shown in Fig. 1. and turned inwardly against the inside face of the body portion, as shown in Fig. 4, the triangular portions II) and the wing portions 8 and 9 will buckle inwardly as shown in Fig. 5, when the body portion I is expanded or formed into tubular shape. The sections 5, however, will remain substantially flat against the inside face of the body portion I, the excess material in the rim portion being relieved by causing the triangular portions I0 and the wing portions 8 and 9 to buckle inwardly. The free ends of the wing portions 8 and 9 thus provide, in effect, a shoulder upon which the end closure may be supported.

In assembling the bottom of thecontainer to the body member, vthe bottom rim portion a is folded inwardly against the inside face of the body portion I, either before or after the body member has been assembled into tubular form. An insert piece C, formed of relatively stiff, strong paperboard material and having a peripheral dimension which will cause it to snugly seat within the body member, is telescoped into the expanded body. member, as shown in Fig. 6. The insert piece C is brought down to seat against-the inturned tab portion 6, the rim portion 25 of the insert piece snugly seating against the inside face of the body portion I, holding the body portion expanded in the desired cross-sectional shape.

An end piece B is then telescoped into the rim portion A, as shown in Fig. 6, and is forced inwardly until the peripheral edges thereof snap over the free ends of the wing portions 8 and .piece B will seat upon the shoulders I3 formed by the inwardly bulging wing portions'8 and 9.

In this position the inside face of the end lpiece B will seat against the outside face of the tab.

portions 6. The end piece B is made of such size as to snugly fit within the rim portion when forced in by pressure. It will be noted that the end'piece B forms, in eiect, a brace or a strut, which prevents the rim portion A from collapsing inwardly and maintains the sections of the rim portion pressed outwardly against the inside face of the body portion I. 'I'he score line I2, which denes the tab portions 6 from the sections 5, is so spaced and arranged as to permit the tab portions 6 to fold snugly over the inside face of the end piece B and at the same time time hold the end piece B snuglyt seated against the shoulders I3 ofthe wing 'portions 8 and 9. The peripheral edge 20 of the end piece B snugly seats against vthe sections l'of the inturned rim portion and seats over and 5 against the shoulders I3 of the inwardly bulging wing portions 8 and 9. As thus arranged, it will be noted that the inturned tab portions 6 are clamped between the end piece B and the insert d isc C, providing a strong and rigid container 1o which may be assembled. withoutthe use oi! glue or other securing means. The end piece B and insert disc C mutually reeniforcev and strengthen one another, providing' a bottom construction which is strong, durable and substantially leakproof, rigidly and strongly bound to the body member. An opening 2i or other suitable means may be provided to facilitate grasping the end piece B while inserted in position. 'I'he opening 2l also provides a convenient means for forcibly removing the end piece B in the event that it is used asv a closure cover for the container. The container is now ready to receive thev contents F.` 'As'shown more particularly in Figs. 9 and 10,

the filled container may be closed by an end closure construction similar to the end closure construction heretofore described. As shown more particularly in Fig. 9, the body member A may be provided with a top rim portion b similar to the bottom rim portion a previously den scribed. When the container is filled with the contents F, the top rim portion b is arranged as shown in Fig. 9. When the desired quantity of contents F has been inserted, an insert piece C is telescoped into the container through the open end thereof, the rim portion b is then folded inwardly until the tab portions 6 seat against the outside face-of the insert disc C, as shownin Fig. 10. The insert disc C is made slightly oversize in dimension so that the peripheral edge 25 40 thereof will frictionally grip the inside face of the body portion I, so that the insert disc C will be sustained in any position in which it is placed. Generally, the contents F extend to the point where top insert disc C would rest upon the contents F, in which position the inturned tab portions 6 will snugly seat thereagainst. The end piece B is then inserted in position to snugly seat -against the outside face of the inturned tab portionst and rest against the shoulders I3 of the wing portions 8 and 9. 'I'he top end piece B is of somewhat oversize dimension so as to provide in effect .a strut or brace which presses' against the sections 5 of the inturned top rim4 piece B may be brought into firm pressing engagement against the inturned tab portions C by placing the filled container in an upside-down' position so that the weight of the contents F will press against lthe top insert disc C.

Whilel the top closure cover construction as illustrated in Figs. 9 and 10 has many advantageous features where a closed drum type con tainer is desired, it is understood that the cons tainer may be provided with a top closure of anyi other desired construction. In Figs. l1 and 12 there is shown for purposes of illustration a container having a bottom constructed as hereinabove described and as illustrated in Fig. 8. 'Ihe top of the body portion, however, is provided with a flange 53 which may be hinged to the body portion I along the transverse score line 54 and 75 turned outwardly or inwardly against the -body portion. The ange portion 53, may, however,

be separately formed and secured in any desirable manner to the upper end of the body portion I. As shown in Fig. 12, a telescoping cover may be provided having a top portion 50 and a down- 5 wardly extending ange por-tion 5 I An upturned lip 52 may be associated with the iiange portion 5I to interlock or engage with the flange 53 associated with the body portion. The cover ange portion 5| may be made to telescope either within 10 or outside oi' the body portionA` I as desired. Any other convenient and desirable cover construction may be provided for the container.

The container as herein disclosed may be formedrentirely from paperboard material. The 15 body members A, the insert discs C and the end pieces B may be c ut and scored by automatic machinery at a high production rate. The body member A may be provided with longitudinallyv extending score lines 3 which permits flat col- 20 lapse of the body member during shipment and storage, thus occupying a minimum of'space. It is understood that Athe body member may be formed from a flat blank, as shown in' Figs. 1 and ll, or may be formed by spiralling or other-A 25 wise forming the iiberboard on a mandrel so as to provide a substantially seamless tubular body member, which body member may be suitably scored to permit collapse thereof for shipment and storage purposes, 'I'he end pieces B may 30 be provided with an opening 2l or a tab or other handle means may be provided, if desired, with which to grasp the end piece during insertion thereof. The paperboard material forming the container may be coated with wax or other ma- 35 terial'to render the same. substantially liquidproof. Due to the fact that the insert disc C is made of slightly 'oversize dimension to snugly seat and press against the interior of the bodyv portion I, and due to the further fact that the 40 end piece B .snugly seats against the inturned rim portion, a substantially liquid-tight and siftproof container is provided adapted for the packaging of such materials as ice cream, frozen ices,

kviscous and semi-liquid materials, as well as pow- 45 dered and granular materials of all kinds. The. container may be made in any size or dimension and may be made generally circular, polygonal, elliptical, or arcuate in cross-section. The container may be manufactured at very low cost, so that it can beeconomically used butv once and then thrown away. A container having similar top and bottom end closures, such as shown in Fig. 10, is `admirably adapted'for certain uses, particularly where a drum or barrel-type container is desired which is sealed and closed until openedby the user. For. other uses containers having other forms of top closure construction, such as shown for' purpo of illustration only inv Fig. 12, may be provided. Containers construct- 60 ed in accordance with this invention may be used for the packaging of numerous products, as will be evident to those skilled in the art.

While certain novel features of the invention have been disclosed and are pointed out'in the 65 annexed claims.- it will be understood that various omissions, substitutions and changes may be made by those skilled in the art without departing from the spirit of the invention.
