14 claims;

This. invention relates generally to containers and is more particularly directed. to a container composed. of fibrous materiaLadapted to be utilized asan original package in dispensing various kinds of goods, and the. method of. producing the same.

As is well known, fiber containers of various forms are now available for marketing numerous products. However, in the distribution of many materials, especially those. that are subject to rapid deterioration unless adequately protected against fluid penetration, the use of fiber con-.

tainers has been more or less limited, largely because of thefact that heretofore it has notbeen possible toeconomically manufacture a fiber con.- tainer that is not only durably leak-proof and i111.- pervious to moisture penetration,,which are most essential, but light in weight. and of av rugged construction. Manifestly, in. the marketing of 'man rproducts'whichare customarily put outin so-called. bullccontainers, the gross weight of.

the package and the capacity of the container to withstand. rough. handling in shipping are im portant factors. 7

Therefore, the primary object of thisinvention is to provide afiber containerof a simple and economical construction, which is rugged and relative'ly' light in. weight and effectively responds to the requirements. for p-ackaging those materials. in the marketing of which. containers that are leak-proof and impervious to fluid penetration. are essential; my container bein so constructed that it: is feasible tostore the. packaged goods. for long period of time, without the constituent; material of! the container being detrimentally affected, with the resulting-leakage and deterioration of the contained product'as is of commonoccurrence: in the use of existing types of fiber containers.

important object of this invention is toprovidev a. container having an inner bag-lik receptacle of flexible material, in which the contained. product is packaged, and an outer rigid casing, including a, tubular SHBH-Of'bOdY portion,

the receptacle embodying an outer wall of resil iesnt material. and being adapted to be entered within. the shell in a collapsed or semi-collapsed condition, for'expansioninto conforming engagement therewith, the resilient material reacting tofrictionally adheI'BtOfi the shell wall for. locat-' ing. the:v receptacle in. an adjusted position with the'shell' relative to the. ends thereof, and functioning to. maintain the stabilityof thepackage within the casing,...under shiftingload conditions.

a container having an inner receptacle and an outer protective casing as aforesaid, in which the shell or body portion of thecasing issealableby end-formingmembers frictionally entered there- 6. in, the ends of the resilient outer wall of the I packaging receptacle, when. located within the shell functioninglas; internalshoulders for defining the disposition of the end-forming members inwardly of the shell ends. with which they are associated} other resilientelements. being .i'nterposable between the end-forming members of the outer casing and the contiguous. end surfaces of the inner receptacle-to cooperate with the resilient wall of the receptacle in stabilizing the 15 inner load and cushioning the receptacle, inthe completion of the container. I

It is also animportant object of this invention to provide a fiber container, possessingthe characteristics and advantages hereinbeforeset forth,

which may be conveniently hermetically sealed by the packer of the contained. product, for the subsequent removal of the contents inbulk, orby. dispensing them from the container in, such quantities as may, be. desired,.at the option of v the purveyor or'user of the product, as the case may -be. To this end, my invention contemplates hermetic sealing means which may be readily applied. tothe outer casing shell andbodily removed therefrom in a replaceable condition, to admit of bulk: removal of the container contents, the sealingmeans embodying a rupturable areawi-th which a collapsible spout-forming element is associated, for doling out the contents, where it is desired to maintain the seal otherwise intact, as

in dispensing the contained product in small amounts. 7

A further object ofm'y invention is to provide an all fiber container including an outer casing having a tubular shell and end-forming members insertable therein of a composition and so assembled in the completion of the outer casing of the container that the entire structure is reinforced againstv bending forces, the end-forming elements 45, being interlocked with the wall. of the shell in cooperation. with. the end edges. of the resilient wall of. the inner receptacle, in a fiui'd-prooijointure and highly resistant to separation" under constant and shifting. loads.

possessing the aforementioned advantages and characteristics and a method of producing the same in a manner which. may; be expeditiously practiced, so that a. container conformin to my Anotherobjectof. invention. isztop'rovide: invention maybe. most economically manufac- My invention also comprehends a containertured and thereby provide for more extensive use of fiber containers in those fields in which the employment of existing types of fiber containers has been found to be impracticable, because of their high cost, apart from their lack of dependability under the conditions that prevail in commercia1 operations involving the marketing of the packaged products. Also, as will be evident, by utilizing the inner resiliently supported receptacle, as a package, in conjunction with the outer rigid protective casing, I am enabled to produce a much lighter construction than otherwise, without sacrificing strength or durability.

Other objects and advantages flowing from the practicing of my invention will become evident as the description proceeds.

In the accompanying drawings, I have shown a preferred form of container, conforming to my invention, as it may be produced by my simple and economical method of manufacture.

In the drawings:

Figure, 1 is a vertical cross-sectional view of a container produced in accordance with my invention, t

Figure 2 is a top plan view, partly in section, of the container shown in Figure 1, on the line 2-2 thereof.

Figure 3 is an elevational view, partly in sec tion, illustrative of the mode of assembly of the inner repectacle in association with other components of the container.

Figure 4 is' an enlarged fragment of Figure 3, partly in section.

Figure 5 is a fragmentary perspective of an end-liner section adapted for association with an end-forming member of the outer casing and the resilient wall of the inner receptacle; and

Figure 6 is a collective showing, in perspective and section, to illustrate the sequence of steps in the assembly of certain of the container components. I

Referring now to the drawings in detail, in which like characters of reference are employed to designate similar parts in the several views, 10 indicates the shell or body-portion of the outer casing of the container, which is of a tubular shape and produced from pressed chipboard, or other suitable material, in the appropriate length. Preferably, the chipboard, in the production of the shell I0, is spirally wound, the convolutions or windings forming each of the constituent laminations mating in butt joints and being bonded by an appropriate adhesive to the convolutions upon which they are superposed to build up a wall section of the requisite thickness. Silicate of soda has' been found to be a highly satisfactory agent for use in uniting the spiral windings, to produce a strong, rigid shell.

End-forming members H and I2, each of the so-called diaphragm type, are insertable within the respective ends of the shell II), in the completion of the structure of the outer casing, as herein after described. Since both of these endforming members are identical in structure and mode of functioning, the description of one thereof, will suffice for the purpose of this disclosure. Taking the end-forming member I I, as an example, it will be observed that it embodies a stepped marginal portion l3, formed by superimposed concentric discs M and I5 of different diameters, composed of pressed fiber and cemeritedv together throughout the area of their opposed surfaces, the disc M of major diameter having a circumferential area corresponding to that of the interior of the shell or body-portion II), in which it is adapted to be seated, under axially applied pressure. If desired, the endforming members may embody an embedded layer of moisture-proof material, or may be otherwise rendered impervious to moisture penetratio'n, though this is not essential to the practicing of my invention as herein shown.

When the shell II] has been formed, it is ready for the reception of the inner package-forming receptacle of flexible material, having an outer and supplementally applied surface of resilient material, constituting the external wall of the receptacle. Preferably, the receptacle and the outer wall-forming material are independently produced and the resilient material adhesively secured to the external surface of the receptacle, to produce a composite wall construction of unitary characteristics.

In the present showing, the inner receptacle takes the form of a paper bag, as indicated at [9, which is formed in the usual manner to embody a closed end or bottom 19a. The bag is then positioned on a mandrel or otherwise supported in expanded condition, and a sheet of corrugated paper or light-weight paper board of a width less arable bond. The length of the corrugated sheet is such as to provide for the meeting of the opposed edges of the sheet in surrounding engagement with the bag wall, in a butt jointure, as indicated at IBb, or if preferred, they may marginally overlap in the registration of mateable 0pposite end corrugations, to provide a uniform wall thickness in th zone of j ointure of the edges. The composite construction thus produced,

possesses a relatively thin flexible inner wallforming surface and an external wall-forming surface having resilient characteristics, imparted by the corrugations coacting with the web-portion lBa of theexternal wall-forming surface, with multiple advantages in the assembly and use of the container; as will become apparent.

The composite inner receptacle, including the bag I9 and the external resilient wall l6, which hereinafter will be referred to simply as the receptacle I9 forthe sake of brevity, except where specific reference is to be made to the external Wall and its functions, is inserted in'the tubular shell I 0, as shown in view A of Figure 6, in a collapsed or partially collapsed condition, as illustrated in view B of said figure. The receptacle is then expanded by internally applied pressure, as by the hands, in conformation with the inner wall of the shell in, as in view C of Figure 6, the hill surfaces of the corrugations of the external wall l6 of the receptacle frictionally adhering to the shell surface, in the reaction of the corrugated material to the receptacle-conforming step, The frictional pressure generated between the external wall of the receptacle and the shell wall is suflicient to support the receptacle in suspension between the open ends of the shell ID, in any.

distended mouth thereof-L mew D ofFig-u'refi; the openaendi of. the bag extending above 'theother end ofxthe shell, to facilitate'loading'.

Thei'endeform'ing? member 1 may' now be: en, tered'inthe end'offthe shell 10 in juxtaposition to the-liottom ofithe'bag: l8, an ends-liner IT: of corrugatedmaterial or cardboard, or' other suit able resilient material, appropriately shaped, being first located upon thebottom' 1911 of the bag with its web-portion Ila disposed in bagengaging'position; As will beobserved, especial- 1y 'fromi Figure" 4; the circumferential area: of the end-liner I7, conformszto that of the inside of the shell. In; so that-theperipheral edge of said end-liner will be disposed" in: contact throughout its: area. with the opposed; shell surface: v

In theapplication of the end-forming mom,- ber Htotheshell; the disc- Itthereof; is: entered in; the end of the shell: contiguous to the bottjom of the bag [9; as stated, and pressed into close association with the opposed corrugated surface of the end-liner IT, urging't'he lattertoward and int v engagement with the bottom of the bag; with the marginal surface of the end-liner ens gaging the opposed end surface of-theresili'ent wall: I 6" of the receptacle, the latter surface functioning as a shoulder for locating the endL-forih-v ing member H in the appropriate spaced relation to' the end surface of th'shell'; it being ap: parent that the smaller disc lfiiof the end'memher becomes the outer surface thereof. -Ihe diameter of" the disc M of the end member, relative-to the-internal: diameterof'theshell, is such as toprovide for the entry of the disc into position within the shellunder pressure, in a socalled force'fit, so as to attain those advantages ment' therewith, the bottom of the ring abutting upon the opposed surface of the disc M of' the end member; as at Ma; with the inner periphery of" the ring in frictional engagement with the opposed periphery itaof the smaller disc- 15 of the end member H. The cross-sectional dimension of: the wall of the ring Zmobv-iously corresponds. to the width of' the ,baseof" the stepped edge l3of the end-forming member" it, so as to insure a tight fit and form a virtually her metic jointure between the end-closure and the shell'or body portion l. I

For the loading process; the end member-- H and its: retaining ring function as the base of the assembly, the material to be packaged being introduced intothe receptacle tlrrough theth as i been loadedv to the appropriate level, the free portion of the wall is folded upon itself to the levelof the contained material, with the sections forming the fold in: overlapping engagement, as-rat lab inFigure 1:, to form a continuous or uninterrupted end-forming surface, indicated at 2'90. The overlapping receptacle sections, ifpreferred, may/ be: cemented together or otherwise sealed in association. to enhancexth'eintegrity of the closure.

A second end linen I58: is now superimposed upon the'closedmouth; of the bag I 9, in the'man ner. previously" des lihfidi, with reference to the V Figure 4 opposed-tothe counter-pressure of the engaging disc of the end-member [2: which is ne'xtaenteredLin the-open end: of the-shell to press, the end liner l8. into close association with: the

.oppo'sed' surface of: the: bag and the opposed edge" of v the corrugat'ed external wall [5 of the receptacle, the marginal portions of the two-end liners. l1 and 18 being deformed under pressure of the engaging end surfacesof the corrugated wall; of the receptacle, as indicated at" l 'l'b in and minor discs of the endemember' l2 andthe rial, indicated at 2'3, cemented to the outer sur face of the smaller'disc 15 of said member. A-

- collapsible spout-forming element 24', apprcpri ately' shaped; having its base portion 24a, is cemented to the disc l5; in juxtaposition to said aperture said element" being scored along lines, as at 2412; for folding; in the formation of the spout. As will be obvious, by simultaneousl'ypuncturing the paper 23 and thebottom I90, of thebagand shaping the spout, the con-- tents may be poured from the container. aperture 22; isscalable thereafter as desired.

For theremoval of the" contents, with the receptacle intact, or for removing the contents from; the receptacle in bulk, the split ring 26 is removable by separating its overlapped ends to' strip it from its functioning position in a contracting movement of thering out or engage ment with the shell and end-member surfaces, to afford access to the interior of the shell; .or the ring may bepri'ed upward out of functioning' position, without separating its ends;

To facilitate; unseating of the endmember H;

a when theretaining ring has been removed, a

fiexibletab '25 is provided; one end of which isentered between'the-discs Mand l5 of said memher, when they are cemented together, to virtually become unitary therewith, the free end of the tab being disposable above the ring 211 and the surrounding edge of the-shell, IS, in the sealing of the container, so that it may be grasped to unseat said end member in anupward dislocatin -movement Manifestly; the tab may al'sobe used to simultaneously dislocate: both the endimember- H and the retaining ring 211,, from container sealingposition, if desired; the mode of its use being optional; j

fn' u" of: d p n me so el upon the. f ictional engagement attire respective 20 ant-1121, with the opposed and coactingsurfaces, of" the, end

members H- and i2 and the inner wall-of the As will be noted, especially from Figures 13,-3'1

and 4', the depth of the retaining rings 20, 2f,

end; liner Hi, for similarly: cooperating: with provides for their projection beyond the ends of the shell II with which they are respectively associated, either ring thereby being adaptedto function as the base element and to take the vertical load, as directly transmitted from the filled receptacle to the end-member with which the ring is associated. Thus there is no possibility of movement of the end member relative to the shell, under load, with a resulting impairment of the end seal, as might occur were the ring positioned inwardly of the end of the shell, with the shell end serving as the supporting surface or base.

From the foregoing, it will be apparent that I have devised a simple and highly eificient construction, in which the material packed within the receptacle is amply protected against deimpervious .to moisture penetration, the hermetic qualities of the seal that is afforded in theclosure of the receptacle being augmented by the manner in which the end members of pressure diaphragm properties are interlocked with the body portion and engage the peripheral edges of the respective opposed corrugated end liners, to conformingly press them into sealing position, as described. Obviously, the inner wall of the composite receptacle l9 may be constituted of material suitable to the characteristics of the material to be packed therein. For example, in some instances, the receptacle may be composed of Cellophane, while in others it may be of paper of the desired weight, waterproofed, or otherwise, or a fabric bag-like receptacle may be used, the protective resilient material l6 being united thereto, as set forth. In some instances, as will be evident, the corrugated material l6 may be separate from the bag and independently inserted in the shell in conforming engagement therewith and the bag then introduced into the expanded corrugated sheet and dilated to conform thereto, thecorrugated material thus functioning as a liner, interposed between the bag and the shell wall. Also, as will be evident, a lesser quantity of material than that for which a bag is designed may be packed therein and the container sealed as stated, the corrugated external wall, as pointed out, providing for the location of the receptacle external the shell in properly spaced relation to the ends thereof, for the insertion of the end-forming members, in the position to which the receptacle may have been adjusted for the desired loading, the top and bottom edges of 'the corrugated material, defining the positions of the end-forming members of the outer casing relative to the respective ends of th closed inner receptacle. When desired, as will be clear from the disclosure, the contents of the container may be extracted conjointly with the removal of the receptacle therefrom in packaged condition, as set forth, when the nature of the product permits of this procedure. Thus a container is rendered reusable, merely by inserting another receptacle in the outer casin assembly and rescaling it with the removed end-member and retaining ring or newcounterparts installed, in the manner described, following the receptacle-fillingoperation.

While I have described, my inventionmore or less specifically, with reference to the'embodiment shown, it will be understood that it may take other forms, as to structural details; also that the sequence of the steps of assembly and loading may be varied, to suit convenience in the production and packaging operations, within the spirit and scope of this disclosure.
