This invention relates to receptacles having more than four side faces and an end wall, of any suitable material usually pa r or cardboard, and to flat and partially fol ed i or closed blanks ca able of being formed into such receptacles. Vhen I refer to a receptacle in this specification, I do not exclude such receptacles as caps, cups, covers, trays,
, or carton having an open side top or bottom. J This invention aims to provide receptacles having more than four side faces, and hence possessing any or all of the advantages of such receptacles of wide adaptability to contain non-rectangular objects, of novelty and distinctiveness of shape, or of economy in wall area relative to volume enclosed, but which nevertheless are capable of easyland rapid manufacture by automatic machinery, are particularly adapted for easy and tight closure, and sealing if desired, and are neat in appearance, avoiding when desired any necessity of exposed flaps, ilanges'or exterior surface irregularities or lines `of weakness and disigurement which interfere with the aixing or imprinting of advertising or decorative matter smoothly on the outer faces of the receptacle.
Receptacles of which adjacent side walls form obtuse interior angles and which are made according to my invention are particularly adapted to serve as protecting receptacles for fragile articles, the manner of disposal of the receptacle material affording improved strength and rigidity.
Other objects and advantages of the invention will appear from this explanation of my invention and of typical species of receptacles and receptacle-forming blanks exemplifying my invention and shown in the Vaccoifnpanying drawings. y
My invention is of particular utility in providing receptacles having an end intimately connected with more than four side walls, receptacles according to my4 invention having, if desired, side Walls and an ehd so tightly sealed or otherwise fastened together as to be substantially free from leak- @D age through the joints.

In the illustrated embodiments of my invention I have provided eight sided recepa5 tacles. It will be understood that these embodiments having eight sides are illustrative of a large number of receptacles havin an' end and more than four side faces, and w 'ch una7 be made according to my invention.
eferring to Fig. 1, the blank shown therein formed of an lntegral sheet of oldable material, such as paper or cardboard, includes a polygonal end section 11 having more than four sides adapted to define one complete end '95' face of the desired receptacle having more than four sides, the shape of this end section corresponding to the cross-sectional shape of the receptacle, in the illustrated embodiments V thatof a regular Octagon. A plurality of 10 w of a blank acret tu side Wall sections are provided at least equal in number to the sides of the polygonal end section ll, and having Widths at 'their ends vrespectively equal to the lengths of the corresponding sides of the polygonal end scction. Since in the present embodiment of the invention the polygonal end section is in the form of a regular Octagon, at least eight side Wall sections are provided, and are herein shown as having their ends corresponding in width to the length of a side of the octagonal end section.
At least two ot the side Wall sections thus provided are each directly integrally and flexibly joined at their ends to respective sides of the polygonal end section. In the illustrated embodiment of the invention two such side wallsect-ions l2 and 13 are thus directly joinedv toisides of the polygonal end section ll, preferably as shown, to its opposite sides, the junction lines being defined by fold lines of increased exibility 4l() and Lll, @ther side Wall sections of the blank not thus directly and flexibly joined to sides of the polygonal end section, but necessary to form. a completely enclosing set of side Walls are flexibly joined at their: sides along fold lines of increased flexibility to one or the other of the side Wall sections thus directly joined to the polygonal end section. A group or groups of conjoined side Wall sections may therefore during closing ot the blank into a receptacle be erected as a unit relative to the polygonal end section ll and there folded around this end section.
Preferably as shown, the side Wall sections are disposed in two groups, one of which includes the side Wall section l2, and the other of which includes the side Wall section 13, these tivo groups being capable of being erected relative to the polygonal end section l1 and then fastened or connected together to forni a continuous set oi side Walls.
To enable the side Wall sections (herein shown as in two groups) to be ailixed, for e2:- alnple as shown in Fig. 4 suitable overlapping sections adapted to connect adjacent side ivalls are employed. ?referably as shown, such overlapping sections are provi ded in the form of additional side wall sections similar to those necessary for defining the side 'faces .of the receptacle, and, in the erected position of the receptacle conform to and overlap other side Wall sections. Accordingly, as shown in Fig. l, the blank tor forming the desired octagonal receptacle is provided with side Wall sections in addition to the eight side Wall sections necessary to define the side faces of the receptacle, in the present instance side wall sections 14, 16, 18, 20, :22, and 2d being )flexibly connected to each other and to side Wall section l2, and side Wall sections l5, 17., 19, 2l, 23, and 25 lilrevvise being dei;N ibly connected to each other and to side Wall 1.3. In this way joints between groups mesma side Wall sections may be formed by the overlapping of full-sized side Wall sections, thus avoiding exposed flaps or flanges on the er.- terior of the side Walls of the receptacle.
The blank is capable of being formed into 'an open ended carton such as shown in Fig.
d, by erecting, folding around the polygonal end section ll, and Iastening together, the various side wall forming elements ot the blank. This may conveniently be accomplished by lirst applying adhesive to elements which are intended to overlap, then moving the blank as a whole relative to folding instrumentalities capable of erecting the two groups of side Wall sections relative to the polygonal end section, folding and overlapping them into a tube, and lastly applying a compression to the overlapped joints. Normally the specific instrumentalities suitable for these operations comprise a reciprocating plunger generally conforming to the end and inner side faces of the receptacle, various movable or fixed abutments disposed around the plunger and capable of contacting with the side Wall-forming elements of the receptacle to Wrap them around the plunger as the plungcrmoves with respect to these abutments, and inwardly moving compressor surfaces adjacent the path of the plunger for applying the above mentioned compression to the overlapping joints. Obviously if only the two side Wall sections l2 and 13 of the receptacle were connected to theend section Where they abut, the receptacle would not be tightly closed and would fail to attain maximum ri gidity. Accordingly connecting sections are provided for closing joints between the side faces and the end of the receptacle. These connecting sections, of which six are provided in the present embodiment, indicated by the reference numbers 83, 84, 85, 86, 87, and 88,
are directly flexibly and integrally joined to respective sides of the polygonal end section ll, so that if desired they may be erected relative to the end section 1l by being :forced against abutinents during movement of the blank by a plunger, and in the manner of folding the side Wall sections ot' the blank. Freferably one or more of these connecting sections is engaged between tivo side Wall sections o the receptacle. For example, in the illustrated blank connecting section may upon folding be enclosed between side Wall sections lo and l?, and/or side Wall section 83 rosy be enclosed between side Wall. sections i8 and fis stated above, l deem it preferable to form joints between the groups of Wall sections by overlapping full-sized side Wall sections. For maximum tightness strength and neatness of appearance, it is preferable further to provide suliicient of these side Wall sections to form double thickness side walls between the two or more side Wall sections (herein sections l2 and 18) which are directand integrally joined to the section..
In the embodiment of Figs. 1 to 5, this result is accomplished, in a receptacle ofv eight sides, by providing fourteen side wall sections, (or twice the number of sides of the receptacle minus the number of side wall sections directly joined to the end wall). Thus each of the connecting sections 84 to 88 inclusive may be and preferably is, disposed between two full-sized side wall sections in the nished receptacle. In a finished receptacle made in this way the, connecting sections are not exposed on either the inner or outer sides of the finished receptacle.
In order to manufacture receptacles rapidl the folding of the wall forming arts (bide wall sections and connecting sectlons) may be carried on concurrently, Fig. 2 showing diagrammatically-all of the side wall forming elements of the blank in the process of being erected (by suitable plunger and abutmentinstrumentalities not shown) and particularly showing the two groups of side wall sections being folded into their ultimate enclosing positions relative to each other. Fig. 3, which shows the side wall forming elements more nearly completely folded, shows also the preferred relative positions of connecting sections intermediate side wall sections' of opposite groups.
The fact that the end section 11 has more than four sides, and hence has interior angles between its sides greater than ninety degrees is of particular advantage in erecting and folding the side wall forming elements of the blank in a rapid and expeditious manner. Referring to Figs. 1 and 2, the formation of the receptacle involves the simultaneous fold-- ing of adjacent connecting and full-sized side wall sections, in different directions and above respective angularly related fold lines. For example connecting section 83 and the entire group of side wall sections including the adjacent section 18 are preferably in -motion simultaneously, section 18 around fold lines 18' and 40. and section 83 moving around fold line 83. The obtuse angle between fold lines 40 and 83 permits the adjacent edges of sections 83 and 18 to clear upon a slight folding of these sections, as shown in Fig. 2. Thus likelihood of interference between parts of the blank during folding is prevented, and permits the folding operations to be carried on with rapidity. This automatic clearing of adjacent connecting and side wall sections may be attained in a blank as shown without cutting away the connecting sections adjacent the side Wall sections. Referring to Fig. 1, free outer edges of the connection sections, 83, 85, 86 and 88 are parallel to and adjacent ends of respective side wall sections and are preferably separated therefrom only by sl`ts 99, such as those made by single cutting knives which do not remove any substantial pieces of the stock. The likelihood of thin slivers (intended to be moving removed) remaining between these adjacent parts of the blank and interferin with the neat assembly of the receptacle is t us avoided, while the connectin sections 83, 85,86 and 88 are not decrease in area by cutting away of material to provide for clearance.
This arrangement in the blank of connecting sections joined to sides of the end section, permits these connecting sections, after beine folded into the planes of the side walls, an overlapped with one or moresde wall sections, to be subjected to the compression utilized in fastening the side wall sections. This is of advantage in glueing together the overlapping parts of a rece tacle, as the connecting sections ma be a Xed by pressure to the side wall sections by the same or similar instrumentalities which afiix the side wall sections, and glued joints between these connecting sections and the side wall sections may be made as tight and strong as those between overlapped side wall sections.
Referring to Fig. which shows a complete receptacle made in the above described manner from the blank of Fig. 1, the end section 11 of more than four sides is free intermediate its edges of any line of weakness and disfigurement of the type caused by folding flat material upon itself and subsequently unfolding it. Thus this end of the receptacle is suitable to bear advertising or decorative matter, and is furthermore strong and without tendency to buckle. v
Suitable structure for closing the end of the carton or receptacle opposite to end section 11 is shown in Figs. 1 to 4 as illustrative of yarious types of end closures which may be employed for this last closed end. Referring to Fig. 1 inner and outer sections 90 and 97 are fiexibly joined respectively to the ends of side wall sections 13 and 12. Joint-closure sections 91 and 92. preferably7 having, as shown. outwardly flaring side edges, are iiexibly joined to ends of side wall sections 16 and 22. and triangular jointclosure sections 93. 94. 95 and 96 are iiexiblv joined to outer ends of side wall sections 14. 18. and 24. A preferred order of closing I the end closure sections is first to fold sec-v tion 90 from its upstanding position shown in Fig. 4, transversely of the side walls of a the receptacle into end closing position. This inner end wall section. since it conforms generally to the inner cross sectional dimensions Aof the carton, serves as a positioning member ac'nrately to dispose the flexibly joined side walls in their desired angular relation and thus insure accurate sealing of the receptacle. Joint-closure sections 91 and 92 are then preferably folded over and aixed to section 90, following which the triangular joint-closure sections 93, 94, 95 and.96 are folded down and affixed. Lastly the outer section 97 is folded down and affixed to the vreceptacle of Fig. 7 Which underlying sections and forms a complete end closure for the receptacle substantially flush with the ends of its side Wall faces as shown in Fig. 5.
The alternate form of blank of Fig. 6 differs from that of Fig. 1 in relative proportions of the side walls and end section, in the absence of end closure elements for closing the open octagonal end of the receptacle, and further in the provision of only enough side Wall sections to provide overlapped joints of a Width equal to that of a. single side wall section rather than that of three side Wall sections as in the previouslyT described embodiment. Since, however, sections of the blank and receptacle of Figs. G and 7 correspond to sections of the blank and receptacle of the previously described embodiment, these sections are designated in Figs. 6 and 7 by corresponding reference numerals With the addition of the letter (z. Referring to Fig. 6 theblank shown therein includes an octagonal end section 11El in the form of a regular Octagon. having joined thereto at opposite sides, and flexibly through the provision of fold lines of increased flex ibility 49a and 41a. side Wall sections l2 and 13?. To side Wall section 12a are fiexiblv joined the side jvall sections 16a. 18a, 20a and .22 While to sidewall section 13 are flexibly joined side Wall sections 17, 19a, 21 and 235. Connecting sections 83, 84, 85, 86a, 87a and 88a are flexibly joined to the remaining sides ofthe octagonal end section 11a asin the previously described embodiment. The side wall sections and connecting sections of the blank of Fig. 6 may be erected relative to the octagonal end section 11 and fastened together in a manner similar to' that described for the blank of Fig. 1, the order of folding'and afixing the side Wall and the connecting sections preferably being such that these sections lie in the positions shown 1n Fig. 7 inthe completed receptacle. The is of octagonal form is obviously suitable for use as a. tray, capor cover. which may cooperate Witha similar and interfitting receptacle, or serve as a cover, bottom or end for a separately7 formed tube. i
The modified form of blank of' Fig. 8 and the receptacle made therefrom and shown in following figures illustrate the application of the above described principles of inv invention to receptacles having polygonal end sections of more than four sides and capable of closure in tivo different orders as desired for filling through either aside or an end. In the blank of Fig. 8 and in Figs. 9 to 16, Wall sections are designated by reference numerals corresponding to those eniployed in Figs. i to 5 with the addition of the letter ti.
Referring to Fig. 8 the blank shown there-- i,sa2,715
in includes the octagonal end section 11" in the foim of an irregular Octagon and the side wall sections 12b and 13b joined thereto at opposite sides and defined by fold lines of increased fiexibility, 4Gb and 41h. To side Wall section 12b are fiexibly joined the side wall sections 14", 16D, 18h, Q0", 22h and 2t, While to side Wall sect-ion 13h are flexibly joined the side vwall sections 15", 17h, 19h, Q1", Q3", and 25h. Connecting sections 83", 81th, 85, 8G", 87 and 885 are fiexibly joined to sides of the octagonal end section 1lb intermediate the direct-ly joined side wall sections 12b and 13, connecting sections 84h and 8T preferably having the shape of a full side wall of the finished receptacle.
The parts of the blank of Fig. 8 thus far described are adapted to cooperate to form., if desired. a receptacle having an open top or end. in oid'er to close this open end I afer to provide another end section 11a similar to end section 1lb and fiexibly joined to the side Wall section 12b along the fold line 400, At the opposite side of this end section 11e a flap-30 is flexibly joined thereto along the fold line 41, Connecting sections 83e, 84, 85e, 86e. 87e and 88B are flexibly joined to sides of the octagonal end section 11e intermediate the two directly joined side Wall and flap sections 12b and 30. l
As in the blank of Fig. l. connecting sections 83", 85", 86h and 88b have free edges parallel and adjacent to end edges of adjacent side wall sections and are separated therefrom only by narrow slits 99.
The blank of Fig. 8 may be formed into the open receptacle of Fig. 9 for example by the same operations involved iii forming the open receptacle of Fig. 3 from the blank of Fig. 1, the parts occupying corresponding osit-ions-in the open receptacle. In folding this blank, the non-perpendicular relation of the fold lines about which side wall sections and adjacent connecting sections fold, facilitates rapid folding of these parts Without interference.
The receptacle of Fig. 9 may be filled from its open top and then closed by folding over its top end section 11 and tucking in its flap 3() and connecting sections 83e. 84". 85". 86e, 87@ and 88, the Wall sections 84, 87e and the closing flap 30 preferably lying face to face With side ivali sections of the receptacle. Thus as shown in Fig. 11 one of the side Walls of the closed receptacle formed by the cooperating wall sections 22h. 23h, 87"4 and 87e comprises four thicknesses of material each of which is an extension of another of the side Wall sections of the receptacle. ln this Way a very rigid structure is obtained.
'in the alternate method of forming the blank of Fig. 8 into a receptacle the flap 30 may be turned over upon the section 11 by folding along the line 41e and section 13b may be laid upon iap 3G, by folding aiong the line lid", and side wall section 13D axed to Hap 80, for instance by means of pressure and previously applied adhesive, the blank thus having the collapsed tubular formof Fig. 12 in which it may conveniently be shipped or stored.
The collapsed tube of Fig. 12 may be opened into the open tube of Fig. 13 suitable to receive contents through either of its ends, whereupon the ends of the tube may readily be closed by externally operating inst-rumentalities. .Preferably side wall section 87 is first folded into the end closing position of Fig. 4 then side wall sections 20", 22b and 24:b are folded relative to their attached side wall section 12b and relative to each other to coniforrn to the marginal contour of oppositely disposed end wall sections l1b and 11e as shown in Fig. 15. The connecting sections 86", 87b and 88b are then .folded into end closing position overlapping sections 24", 22b and 20h, and preferably fastened in this position for instance by adhesive. Side wall sections 21", 23" and 25b are then preferably folded and affixed in the positions of Fig. 10.
rlhe alternate form of blank shown in Fig. 17 is in general similar to the blank of Fig. 8 and may likewise be formed into receptacles in two different orders of folding but is provided with a smaller number of connecte ing section. The various sections of the blank of Fig. 17 correspond to those of the blank of Fig. 8 and accordingly are designated by the same reference numerals with the addition of the letters c and f. The blank of Fig. 17 dii'ers from that of Fig. 8 in that side wall sections 22c and 28c are so proportioned relative to each otlgi; nd to side Wall sections 87 and 87t that up `n folding into their ultimate positions side wall sections 22 and 23 do not overlap but substantially abut g1' and are overlapped by sections 87 and 87. Accordingly in the folding of these sections into their ultimate positions side wall sections 2.2c and 23c may, if desired, be folded simultaneously, instead of successively as in the case orl the blank of Fig. '8. li claim:
