This invention relates to containers and more particularly to an improved box or container of paperboard material adapted to be shipped and stored in knockdown form.

This application is a division of my copending application Serial No. 739,408, filed August 11, 1934. r

The improved container of the present invention comprises a tubular body portion which may be formed from a blank of paperboard material. The body portion is provided with a series oi. fingers at one end thereof which are inserted into corresponding spaced apertures or slots pro- An insert disc of strong paperboard material is inserted into the body of the container and seats against the end portions of the fingers which project through the apertures, .thus firmly securing the body member and end closure in fully assembled, setup condition. The body member may be stacked in collapsed, flat condition during shipment and storage, requiring a minimum of space. The end closure and the insert piece are simple flat pieces of paperboard material and are adapted to be stacked in a minimum space until ready for assembling. The body member and insert piece may be quickly assembled together by means of a simple jig tool as the containers are needed. The body member, end closure and insert piece may be cut and scored to the desired shape and form by automatic machinery in common use.

'The container presents a strong and durable construction'and can be'made without hand opei'ation from a minimum of material. The body member and end closure are joined together by the interlocking of the parts and held in this position by the insert disc. The container is most economical to manufacture and produce. It presents a substantially leakproof container.

Another object of this invention is to provide an improved container comprising a body member and an end closure member maintained andset up in an assembled condition by interlocking of the parts.

Another object of this invention is to provide a container comprising parts which can be economically made by means of automatic machinery in common use, which can beshipped and. stored in a minimum of space and which may be quickly and effectively set up at the place of use as needed or desired. 7

Still another object of this invention is to provide an improved knockdown container which may be made entirely of paperboard material with a minimum of waste, which is strong and durable in construction, and which affords an economical and efficient packaging medium for a large variety of different products. I

Other objects of this invention will become apparent as the disclosure proceeds.

The structural members comprising the container include a body member A, an end closure B, and an insert disc C which may be formed of paperboard or fibreboard material. The body member A is formed from a blank of relatively tough yet flexible paperboard material cut and scored in the manner shown in Fig. 2. The body member comprises more particularly a body portion I having a plurality of vertically extending score lines therein causing the body portion when assembled to assume a substantially cylindrical or arcuate cross sectional configuration. The body blank is provided with a tab portion 3 along a vertical side thereof which may be suitably secured by stitching, staples or by a crimping operation, to the other vertical side edge of the blank so as to form a tubular member. The body member A may be provided with a flange portion 4 which may be turned'downwardly to provide a reinforcing and stiffening rim for one end of the container. A notch 5 is preferably cut in the rim portion 4 to permit the body member when assembled inftubular form to be collapsed into fiat condition. The body member may comprise any formof collapsible tubular member within the purview of this invention.

The other end of the body portion is provided with a plurality of laterally extending fingers which are hinged to the body portion I along the score line I. The fingers may comprise the tapered tongues 25, as shown in Fig. 2, which engage the end closure, or, if desired, the fingers may each comprise a rim portion 6, a neck portion 8, and an end portion 9. When the fingers, as shown in Figs. 9 and I0, are turned inwardly, the. rim portions 6 closely abut one another so as to provide a substantially continuous rim around the end of the container. The body member I may, if desired, be provided with tapered tongues 25, as shown in Fig. 2.

The end piece B, as shown in Fig. 3, is provided with a series of spaced slots 21 dividing the same into an outer section l5 and an inner section l6, as shown in Fig. 3. The slots 21 extend outwardly to the edge of the end piece providing therebetween tongues or fingers 26 having outwardly flared shoulder portions 21a. The tongue-receiving slots 21 are easy to cut out and do not clog the cutting die.

An insert piece, as shown more particularly in Figs. 1 and 4, is provided which is adapted to be inserted into the body of the container. The insert piece preferably comprises the half portions 20 hinged together along the score line 2| to facilitate insertion thereof, but the score line may be omitted in many cases.

In setting up the container, the fingers at one end of the tubular member are turned angularly upwardly and inwardly. The end closure B is then telescoped into the tubular body member and the end closure and the fingers relatively adjusted so that the end portions 9 of the fingers are inserted into the respective apertures 21 provided in the end closure. The end closure is then forced downwardly until the end portions 9 project upwardly through the apertures 21 and the end closure comes to rest on the neck portion I of the fingers. when so arranged, it will be noted that rim portions 6 of the fingers, as illustrated more particularly in Fig. 9, may be made to closely abut one another and form a substantially continuous rim at the end of the container. The fingers or tongues, whether in the form as shown in Figs. 9 and 10 or in the form 25, as shown in Fig. 1, may be easily inserted into the slotted openings 2'! providing a bottom construction of great strength and rigidity.

The insert piece C'is then telescoped into the body member, as shown in Fig. 1. The insert piece is preferably slightly oversize with respect to the tubular body member. One of the half portions 20 is advanced downwardly into seating position against the inwardly projecting end portions 9 of the fingers. The other half portion 20 is then forced down into seating position against the end portions 9 of the fingers. When fully assembled the piece C clamps the end portions against the end closure 13 and ofiers great resistance to the withdrawal of the fingers from the apertures 21. Resistance to the withdrawal of the fingers is further increased when the container is filled with contents, since the weight of the contents further increases the clamping force exerted by the end closure B and the insert piece C upon the fingers. The insert piece C may be scored along the line 2| across the mid-section thereof or may be left unscored, as desired.

The body member A and the associated fingers are preferably formed of strong, tough, fibreboard material so as to withstand bending without rupture. The end closure B and the insert piece C are preferably formed of relatively stiff paperboard material which will remain substantially rigid under considerable pressure. The container thus formed is strong and durable and will carry considerable weight without weakening. The rim portions 6 of the fingers form a substantially continuous rim upon which the container may rest, thus holding the end closure B out of contact with the fioor. The end closure B is thus maintained out of contact with wet surfaces upon which the container may rest.

If moist material such as ice cream and other liquid or semi-liquid products are packed in the container, it may be found desirable to coat the end'portion of the container with a layer of wax, parafiin or other waterproofing material. The waterproof material above described may be applied either on the outside or one the inside of the container or both, as found desirable.

There is shown in dotted lines in Fig. l, for purposes of illustration only, a cover member which may comprise a top piece l0 and a rim portion ll telescoped over the downturned flange 4.

It is understood, however, that the end closure above particularly described may be used to form either the bottom end of the container of the top end of the container, or both.

A further modified end piece construction B-2 is shown in Fig. 7. shown is provided with rectangular shaped slots '28 for receiving the locking tongues '25 of the construction the end closure F at the bottom of -.the container, and if desired also the end closure E at the top of the container, may-be provided with spaced apertures or openings I! completely surrounded by paperboard material. At the bottom of the container the tongues extending from the body member I have neck portions 8 which extend through the aperture I 1 of the closure member F. Likewise the tongues extending from the opposite end of the body member I also have neck portions 8 which extend from the closed The end piece B2 here apertures I! in the top closure member E. An it inner liner membenD of tubular form may be provided over which the bottom member F, shown in Fig. 10, and the lid member E, shown in Fig. 9, are telescoped. The liner member D comprises a tubular side wall 30 provided at its lower end with a series of taper tongues 3| preferably scored at its juncture with the side wall 30.

The tubular body member D and the bottom closure are assembled together by first bending the tongues 3| inwardly, and then inserting the liner member D within the cylindrical side wall portion l of the body member until the tongues 3| overlie the outer section I5 of the end .piece C. An insert disc C is then telescoped into the liner member and thrust downwardly therein until its peripheral portion overlies and contacts with the upper surface of the tongues 3|, it being appreciated the contact will simultaneously be made with the upper surface of the tapered tongues 6, the parts being thus held together. The lid E used on this container is constructed similarly to the bottom closure member F and telescopes over the tubular portion 30 of the liner member D. The bottom portion F and the lid portion E may be made of such size as to abut and snugly fit against the inside face of the body portion I to provide a substantially leak-proof and sift-proof construction when the bottom and lid portions are applied.

There is shown in Figs. 11 to 14 inclusive a rectangular shaped box made in accordance with this invention. The box side walls 33 are formed from a single blank of cardboard, paperboard or fibreboard having vertical score lines 34 and horizontal score lines 31, the end of the blank being connected together by stapling or adhesive or by a tongue 35 and slot 36, as shown in Fig. 14. Depending below each horizontal score line is a flap 38, each of which is provided with a series of tapered depending tongues 39. The end tongues 40 are somewhat shorter in length than the fingers 39, the outer edges of fingers 40 being cut oil at an angle approximately 45", as indicated at 4|. The side edges of the flaps 38 are also cut off at an angle of approximately 45 to align with respective end tongues. tangular end piece 42 is provided with a series of slots or apertures 43 along each marginal edge thereof to receive the tongues 35. At each corner of the end piece 42 there is provided an elongated slot 44 adapted to receive adjacent pairs of end tongues 40.

The root portions of the tongues 39 are provided with notches 45 whereby the end piece 42, after being assembled with the body member, can

be shifted slightly longitudinally and transversely.

to thereby interlock the end piece 42 and the body member together. A rectangular shaped insert 46 may be provided to overlie the ends of the tongues 39 and hold the same firmly against the end piece 42.

The containers may be formed entirely of paperboard material which may be cut and scored entirely by automatic machinery. The container may be assembled either by hand or by a simple jig tool. The body member may be assembled into tubular form and then shipped and stored in flat collapsed condition. The end closure and the insert piece may be stacked one upon the other during shipment and storage, occupying a minimum of space. The setting up of the contalner may be performed by the packer as needed. Containers of cylindrical and rectangular form are herein shown for purposes of illustration only.
