taken substansubstansubstan- Referring now more particularlyto the-drawings, and
specifically to Figure 1 thereof, the embodiment of the invention illustrated therein constitutes a blank, generally designated 20, preferably fabricated of one piece of cardboard or other suitably stiff sheet material. Theblank 20 f includes a generally rectangular main panel 21 bounded along its front and rear edges, respectively, by parallel fold lines, creases or scores 22 and 23, and along its opposite side edges by parallel fold lines. or scores 24 and25, which extend between the front and rear edge fold lines; Extending laterally outwards from the side edge fold lines 24 and 25, respectively, and longitudinally coextensive therewith, are generally rectangular lateral extensions or side panels 26 and 27. That is, that the lateral extensions 26 and 27 are hingedly connected to opposite side edges of the. main panel 21 by the fold lines 24 and 25, respectively. Hingedly connected to the outer edges of the side panels or extensions 26 and 27, as by fold lines 28 and 29, are generally rectangular side flaps 30 and 31.
A generally rectangular forward extension or section 35 extends along the front edge of the main panel 21, 7
being coextensive therewith, and is hingedly connected tothe main panel by the front edge fold line 22. The
Patented Oct. 14 1958 substanforward panel 37 to the outer boundary. or: edge of, the
forward extension. The forward panel 37 is laterally coextensive with the forward extension 35,, vso,.that. the
side edges of the forward extension and forwardpanel are in alignment with each other and with the, side creases; 24 and 25 of the main panel. A laterally extending. fold line 38 defines the forward boundaryv of the-forward panel:
37 and serves to hingedly connect an additional, generally rectangular. panel 39 to the forward panel 37. Theadditional panel 39 has its outer boundary defined by a fold line 40 parallel to the fold line 38, and is laterally. coextensive with the forward-panel 37, so that the side edges of the former panel are in alignment with the side edges of the latter panel.
It will be noted that the. forward panel 37 is formed with a plurality of laterally spaced through apertures or through openings 42 of generally elongate configuration in the forward and rearward direction. More particularly, each of the apertures 42 has its opposite end portions43 and 44 extending through and beyond the fold lines 36 and 38 into the extension 35 and panel 39 but terminate short of the fold lines 22 and 40. Viewed otherwise, the aperture end portions 43 may be considered as a plurality of laterally spaced cutouts formed in the extension panel 35, and each opening through the fold line 36 into a respective one of the forward panel openings 42. Similarly, the aperture endportions 44 may be considered as a plurality of laterally spaced cut outs each opening through the fold line 38 and into its respective, forward panel aperture 42.
Hingedly connected on the forward edge of the additional panel 39,;by' the fold line 40," is a generally trapezoidal tab or flap 45;
Coextensive with and hingedly connected to the. rear, edge of the main panel 21' by the. foldline or crease-.23 is a generally rectangular rearward extensionror section.
48, which hasits side edges in alignment, respectively,
withthe side edge creases 24 and 25 of the main panel, and has its outer boundary defined by a fold line or crease 49 extending parallel to the crease 23. Extending rearwards from the rearward section 48 and hingedly connected to the latter by the fold line 49, is a rearward panel 50. The rearward panel includes an inner portion 51 of somewhat rectangular configuration, which is laterally coextensive with the contiguous rearward extension or section 48, and a somewhat'rectangular outer portion which is offset laterally from the inner portion and of the same lateral dimension as the inner portion. The rearward panel 50 also includes an intermediate portion 53 extending-between-and connecting'the inner and outer portions l-and 52'.
The intermediate portion'53 of"the rearward'panel'50. has its opposite side edges 54-and 55tdisposed in parallelism with each other and extending obliquely with respect to the parallel fold-lines 2'3and'49'. Further the intermediate rearward panel portion 53" is providedjwith a plurality of laterally-spacedthrough cuts or slits- 5 6: which extend parallel -to-each other and tothe side edges 54 and 55, so as to be oblique-to the fold lines 23' and 49; It will now be appreciated thatthecutsorslits 56jformed in the intermediate rearward'panel portion 53 serveto define in the lattera pluralityofparallelstrips 57E-extend ing oblique to the fold line =49-and rearward'section 48;. Stated otherwise, the panel portion-57 in the'space between each adjacent pair of" cuts 56 defines astrip 57 extending oblique tothe fold line-49 'an-d section 48. It will be noted that the.strips;57 areone greater in number, than the forward-panel apertures 42; andthat the strip mesons? lowermost fold line 58 in Figure 1).
formed in the intermediate rearward panel portion 53 each extending from the outer end of a respective cut 56 inwards toward and terminating at a point of intersection with the next adjacent cut. That is, all of the fold lines 58 terminate at their inner ends at the next adjacent cut except one endmost fold line 58 which terminates at one side edge of the intermediate rearward panel portion (the Another group of laterally spaced parallelfold lines 59 are formed in the intermediate rearward panel portion 53 each extending generally outwards from the inner end of a respective cut 56 toward and terminating at a point of intersection with g the next adjacent cut, all except one endmost fold line 59 defining cuts 56 are arranged'so that thespace between (the uppermost in Figure 1'), which terminates at a side edge of the intermediate rearward panel portion. Further, the fold lines 58 and 59 are parallel to each other. In the illustrated embodiment of Figure l the fold lines 58,, and 59 are. substantially; normal or perpendicular to thefold-line or crease 49'; however, this relationship may advantageously be-modified, as will appear hereinafter in, greater detail.
1n setting up or erectinga carton from the blank of, Figure, 1, the .fiap 45 is swung rearwards about the fold line 40, the panel 39 and, flap 45 are rearwardly swung together about the fold line 38, the flap 45, panel 39 and panel 37 are rearwardly swung together about the foldline 3,6, and the flap 45, panels'39 and 37, and forward extension 35 are rearwardly swung together about the, fold, line 22. Thiscondition is illustrated in Figure 2. Alsofas shown in Figure. 2, the rearward panel 50 has been swung;forwards about the foldline 49 and the rearwardpanel 5,0 and rearward extension 48 have. been swung forwardstogether about the fold line 23. The side .llaps .and 31 may then be swung inwards about their respective fold lines 28 and 29, and the lateral extensions, 26.and 27 swung inwards together with their contiguous. side, flaps about. theirrespective fold lines 24 andf25.
Theforward flap 45 may then be secured in facing engagement with the upper surface of the main panel 21 so that the extension defines an upstanding forward wall on themain panel, and the forward panel extends rearwards from the. upper edge of the forward wall. in parallel spaced relation overthe main panel, being supportedalong its inner edge by the additional panel 39. This construction is best seen in Figure 8, wherein the flap extends forwards from the lower edge of the panel 39'andis secured by any suitable means to the main panel'21 directly below the panel 37. Of course, the flap .45 may extend rearwards from the lower edge of the panel 39, and be there secured to the main panel 21, so astoprovide the desired box-like forward endstructure. Figure 9'illustrates, thev box-like structure of Figure 8 in collapsed or folded condition.
The intermediate portion 53' of the rearward panel may then be bentalong the fold lines 58 and 59 to swing.
the outer portion 52 of the rearward panel into a plane parallel to but spaced from the plane of the inner rearward panel portion 51. That is, the strips 57 defined between the cuts 56, are each connected at its opposite ends by a pair of parallel folds 58 and 59 to the outer and-inner portions 52 and.51, respectively, of the rearward panel 50, and'serve to connect such portions for relative movement between a coplanar and a spaced, parallel plane relation. Further, the strip dimensions are such that the outer portion 52 of the rearward panel swings: into lateral alignment with the inner rearward panel portion 51 and at a.perpendicular distance from the plane of the latter equal to the dimension between the fold lines 2.3;and ,49, when the strips are substantially normal to the inner and outer rearward panel portions.
Hence, with, the rearward extension or section 48 swung to a generally, normal, upstanding relation with respect to the main panel;21, the inner rearward panel portion 51 defines a ledge extending forwards from the assaoer upper edge of the section 48 in parallel spaced relation over the main panel, and the outer rearward panel portion 52 rests in facing engagement on the upper surface of the main panel in laterally coextensive relation with respect thereto. Securement by any suitable means of the rearward panel portion 52 to the main panel serves to maintain the strips 57 in their laterally spaced relation of Figure 3 disposed generally normal to and extending between the ledge 51 and main panel 21, while the rearward extension or section 48 defines an upstanding rear wall on the rear edge of the main panel.
In this condition it will be appreciated that the main panel 21 defines a bottom wall for the erected carton, and that each of the forward panel apertures 42 is disposed opposite to and opens rearwards through its associated cut out 44 toward a respective space between an adjacent pair of the strips 57. That is, each of the interstrip spaces and a respective one of the openings 42 are located in forward and rearward alignment with respect to each other.
By way of example, a delicate object of elongate configuration, generally designated 63, is shown in Figure 5 as a hypodermic needle. As illustrated, the hypodermic needle 63 includes at one end a cylindrical medicine holding chamber 64 which is usually fabricated of glass or other transparent fragile material. A connector or coupling 65 is secured on the inner end of the glass cylinder 64 for rigidly connecting a needle proper 66 to the cylinder. The needle 66 may conventionally include a removable protective sheath of rubber or other suitable material.
In packing or filling the carton of Figure 3 with a plurality of delicate objects 63, the distal end of the cylinder 64 of each object is inserted rearwards beneath the ledge 51 through the space between an adjacent pair of strips 57. This relationship is shown in Figure 4, wherein the cylinders 64 are illustrated in dot-and-dash outline. Remote from each cylinder 64, the forward or distal end portion of each needle proper 66 is received in a respective forward panel opening 42, as seen in Figure 7. The strips 57 thus serve to separate and restrain lateral movement of the cylinders 64, while the panel openings 42 prevent lateral movement of each needle proper 66. Rearward and forward longitudinal shifting of the article 63 is effectively limited by the rearward and forward carton walls 48 and 35. In the case of rearward article movement, the cylinder 64 will, of course, abut against the rear wall 48. Similarly, upon forward shifting of the articles 63, the distal ends of the needle 66 will abut against the front wall 35. outs 44 formed in the inner forward wall or panel 39 serve to support the needles 66, and are of greater depth than the cut outs 43, so that the needles may not shift forwards through the latter cut outs without being at least slightly elevated. Such elevation is prevented by the generally open ended tubular sheath or cover 68 extending laterally about the carton 20.
As best seen in Figure 7, the cover 68 is of tubular, open ended generally rectangular cross-sectional configuration to slidably and conformably receive the carton 20 and prevent removal of the articles 63 from the carton. However, upon partial withdrawal of the carton 20 from the cover 68, the condition seen in Figure 7, the article needle. 66 may be slightly elevated and withdrawn forwards and upwards from the carton.
In figure 18 is shown a slightly modified form of blank Zita, which is similar to the first described blank 24) and is adapted to be stored in a partially erected, but collapsed condition. The blank 20a includes a generally rectangular main panel 21a similar to the panel 21, but provided with a pair of parallel spaced cuts or slits 70 and 71 which extend diagonally of the panel and generaliy parallel to the cuts 56a of the rearward panel 59a. Lateral extensions 26 and 27, and side flaps 30 and 31 are provided as in the blank 20.
That is, the cut Extending forwards from the front end of the panel 21a is a generally rectangular forward extension or section 35a, which is substantially the same as the forward extension 35 of Figure 1 but which is not provided with cut outs corresponding to those at 43 in Figure 1. A forward panel 37a is hingedly connected to and extends forward from the extension 3511, similar to the forward panel 37, and is formed with a plurality of laterally spaced apertures 42a corresponding to the apertures 42, but terminating at the hinged connection between the extension 35a and panel 37a.
An additional panel 39 having cut outs 44 is hingedly connected to the forward edge of the panel 37a, and a forward flap 45 is hingedly connected to the panel 39, all as in the form of Figure l.
Hingedly connected to the rear edge of the main panel 21a is a rearwardly extending generally rectangular section 48, the same as in Figure 1. Hingedly connected to and extending rearwards from the rearward section 48 is a rearward panel 50a which includes an inner portion 51a laterally coextensive with the section 48, an outer portion 520: laterally offset from the inner portion, and an intermediate portion 53a extending between and connecting the inner and outer rearward panel portions. The inner and intermediate rearward panel portions 51a and 53a are substantially the sameas the inner and intermediate panel portions 51 and 53 of Figure 1, however the outer rearward panel portion 52a differs in being provided with a pair of laterally spaced tongues or tabs 72 and 73 projecting laterally in the offset direction of the outer rearward panel portion.
The procedure for erecting a carton from the blank 20a is substantially the same as that described hereinbefore in connection with the blank 20 except that the tongues 72 and 73 are inserted through the cuts and 71 instead of otherwise securing the outer rearward panel portion 52a to the main panel 21a. The inherent resilience in the rearward panel 50a tending to return the inner and outer portions thereof to their coplanar relation will retain the tongues 72 and 73 in their respective slots 70 and 71.
It will now be understood that the blank 20a may be stored in a partially set up, but substantially collapsed condition, wherein the forward box-like structure of the section 35a, panels 37a and 39, and flap 45 may be collapsed to a condition such as that shown in Figure 9 and the rearward panel 50a may rest on the main panel 21a either with or without the intermediate rear panel portion 53a folded along the lines 56a and 59a. This, of course, makes for economy of space in storage and extremely rapid set up for filling.
The absence of cut outs in the extension 35a, which defines the forward carton wall, may be desirable under certain circumstances, especially where the article being packaged is of such dimensions that even a small forward wall cut out would allow forward shifting move ment of the article.
Another slightly modified form of blank 2% is illustrated in Figure 11, which also permits of being stored in a partially set up, but completely collapsed condition. The blank 2% includes a generally rectangular main panel 21b substantially identical to the main panel 21, but provided with a pair of parallel through cuts or slots 76 and 77 disposed oblique to the configuration of the main panel and generally normal to the cuts 56b of the rearward panel 58b, as will appear presently in greater detail. Extending forwards from the front edge of the main panel 21b are a forward section 35a, a forward panel 37a, an additional panel 39, and a flap 45, all substantially identical to that of Figure 10. Side panels 26 and 27, and side flaps 30 and 31 are provided on the side edges of the main panel 21b substantially the same as in the forms of Figures 1 and 10 described here inbefore.
A rearward section 48 extends from the rear edge of the main panel 21b, as in the forms of Figures 1 and 10, and a-rearward panel 501; is hingedly connected ,to the rear or outer boundary of the rearward section. The rearward panel 50b has itsinner portion 51b and intermediate portion 53bsubstantiallyidentical to the inner and intermediate portions 51gand, 53 of the rearward panel Stl'in Figure 1, but the outer portion 52b of the rearward panel 50b is provided on itsouter edge with a pair of laterally spaced generally parallel tabs 78and 79 which extend generally normal to the'cuts 56b.
The blank 2Pb of Figure 11 is erected or set up in substantially the same manner as the blank 20 of Figure 1, except that the tabs 78 and 79 are inserted through the slots 76 and 77, respectively, instead of otherwise securing the rearward panel 5% to the main panel 21b. The outer rearward panel portion 52b is shown in dot-anddash outline in its set, up condition with the tabs 78 and 79 inserted through the slots 76 :and 77. It will be noted that the angular disposition of the slots 76 and 77, and the tabs 78 and 79'facillitates erection in that endwise insertion of the tabs through the slots may be effected simultaneously, with folding of the rearward panel 5012 along its fold lines 56b and 59b. Once inserted in the slots 76 and 77, the tabs 78 and 79 may be folded under the main panel 21b to retain the tabs in the slots.
For economy of space in storage and convenience in filling or packing, the blank b of Figure 11 may be stored in its partially erected, substantially flat condition of Figure 12, wherein-the extension a, panels 37a and 39, and tab are folded flat on the main panel 21b, and the rearward panel 591), with its intermediate portion folded along the lines 56b and 59b, is also superposed substantially flat on the main'panel.
A further embodiment of the invention is illustrated in Figures 13l9, wherein a blank 200 is adapted to be formed into a carton of the present invention. The blank 20c includes a generally rectangular main panel 210 similar to the main panel 21 of thejfirst described form, but provided along its rearward boundary or edge with a plurality of laterally spaced upset portions or pads 84. More particularly, the pads are formed of the main panel material, as best seen in Figure 17, and are arranged in a series or line adjacent to and spaced inwards from the rearward edge of the main panel. A pair of side panels 26 and 27 extend laterally from opposite side boundaries or edges of the main panel 21c, each having a side flap hingedly connected thereto, as at 30 and 31, as in the form of Figure l.
A generally rectangular section 350 is laterally coextensive with and hingedly connected by a fold line 22c to the forward boundary or edge of the main panel 210; and, a forward panel 37c is laterally coextensive with and hingedly connected to the forward edge or crease 36c of the extension 35c, so that the side edges of the forward extension and forward panel are in substantial alignment with each other and with the side boundaries of the main panel 210. Formed in the forward panel 370 are a plurality of laterally spaced apertures or openings 42c of forward and rearward elongate configuration. More specifically, the openings 42c are arranged in side by side relation each in substantial forward and rearward alignment with a respective one of the pads 84, terminating at its inner end substantially coincident with the hinged connection 360 between the forward panel 370 and section 35c, and having its outer end terminating short of the outer bounding fold line 380 of the forward panel. Further, the forward panel 370 is shaped to define a plurality of points or protrusions 35 each projecting laterally into a respective one of the cut outs 42c intermediate the ends thereof. Hingedly connected along the outer or forward boundary 38c of the forward panel 370 is a flap 450.
A generally rectangular section 480 is laterally coextensive with and hingedly connected by the fold line 23c to the, rearward boundanyzofwthe main :panel 21c, corresponding-to-the rearward extension 48 of Figure 1. A rearward. panel'50c is hingedly connected, as by a fold line-or crease 490 to the rearward boundary or edge of-the section 486, and includesan inner portion 510 contiguous tothe latter-section, and outer portion 520 offset' laterally from the inner portion, and an intermediate portion-53c connecting the inner andouter rearwardpanlportions; The intermediate rearward panel portion-53c is formed with a plurality of laterally spaced through cuts or slits 56c disposed in parallelism with each other and oblique to the forward and rearward boundaries 22c and-2300f the main panel 210. Further, the side edges of theintermediate rearward panel portion 53c are parallel to the cuts 56c. Also formed in the intermediate rearward panel portion 53c are a group of parallel fold lines- S8c each-extending generally inwards from the-outer end of a respective cut 56c and terminating at a'point of'intersectio'n'with the'next adjacent cut; and, an additio-nal group of parallel fold lines 59c are formed in the intermediate rearward panel portion each extending generally outwards from the inner end of a respectivecut '56'cwand terminating at a point of intersection with thenext adjacent cut.
InFigure 13 it will benoted that the fold lines 580 and 59care.substantially parallel to each other, and extend oblique to the forward and rearward boundaries of the main panel 210, at an angleslightly less than perpendiculartosuch.boundaries. The intermediate rearward panel portion. 530 maybe considered as composed of a plurality ofsparallelstrips 57c extending oblique to the forward and rearward boundaries of the main panel 21c and each defined by the material inthe space between an adjacent pair ofycuts 56c.and. a pair of fold lines 58c and 59c extending between the respective adjacent pair of-cutsa Further, the endrnost foldlines of each group 580 and, 590 intersect withrthe side edges of the intermediate, rearward panel portion .530, which edges and fold lines combinedwiththe endmost cuts 56c to define the endrnost strips,57c. From Figure 13 it will be observed that :the space between the forward ends of each adjacent pair of :strips 570 is in substantial forward and rearward;alignrnent withthe adjacent pad 84 and a respective forwardpanel opening 420, for purposes appearing presently in'greater detail.
Hingedly connected to the rearward boundary or edge of. the rearward panel 500, as by a fold line 87 parallel to thefoldline 49a, is agenerally rectangular auxiliary panel ,88. Moreparticularly, the auxiliary panel 88 is laterally coextensive withT.the outer portion 52c of the rearward panel 50c, andprovided with a plurality of laterally spaced forwardly and rearwardly elongate through apertures or holes 39. It will be noted that each of the auxiliary panel apertures 89 is in forward and rearward alignment with-a respective space between the rearward ends of adjacent pairs of strips 570. The holes 89 are equal in number to the pads 84 and openings 420, each hole being laterally offset from an aligned pair of pads and openings a distance equal to the offset of the outer'portion of the rearward panel. The outer boundary of the auxiliary panel 88 is defined by a laterally extending-fold line or crease90, while a fold line or crease 91 is formed in the auxiliary panel extending laterally therealcng parallelto and substantially equi-distant between the fold lines 87 and 90 so. as to intersect each of the holes 89 at approximately its medial region. Hingedly connected to the outer boundary or edge of the auxiliary panel 88, by the fold line 90, is a generally rectangular section or flap 92.
In setting up or erection of the blank 20c, the extension or section 480 may be first swung upwards about the rear edge fold 23c of the main panel 21c, after which the rearward panel 500 may be folded forwards about the hinged connection 490 of the rearward panel and section 43c. The rearward panel 500 may then be folded along the lines 58c.;an d..59c to swing the outer rearward panel portion 52c into a plane parallel to and spaced from the plane of the inner rearward panel portion 510. That is, the outer rearward panel portion 52 is swung into lateral alignment with the inner rearward panel portion 51c and into facing engagement with the upper side of the main panel 21c. In this condition, the outer rearward panel portion 52c may be secured to the main panel 210 by any suitable means, and the strips 570 will be disposed in laterally spaced relation extending between the inner and outer rearward panel portions. As the fold lines 58c and 596 are disposed oblique to the forward and rearward boundaries 22c and 230 of the main panel, the strips 570 will, in horizontal section, extend oblique to the forward and rearward main panel boundaries.
The auxiliary panel 88 may then be folded upwards along the connection 87, and downwards along the intermediate fold line 91, with the flap 92 swung about the fold line 90 to extend forwards in facing engagement with the upper surface of the main panel. The auxiliarypanel 88 will thus define a laterally extending ridge, with the fold 91 the crest of the ridge, and the holes or apertures 89 opening upwards to define a plurality of laterally spaced notches in the ridge.
The forward extension or section 350 may then be swung upwards about the fold line 22c, and theforward panel 37c swung rearwards about the fold line 360 to a rearwardly declining position, with the flap 45c swung about the fold line 380 to a position superposed on the upper surface of the main panel 210 and the flap 92c, see Figure 18, in which condition the flap 450 may be secured by any suitable means to the main panel.
It will now be apparent that the main panel 210 defines a carton bottom wall, while the forward and rearward extensions or sections 35c and 48c define upstanding front and rear walls on the front and rear ends of i the bottom wall. Further, the inner rearward panel portion 510 provides a ledge (see Figure 15) extending forwards from the upper edge of the rear Wall 48c over the pads 84, and the strips 570 depend in parallelism with each other from the forward region of the ledge to the bottom wall 210 with each pad 84 adjacent to the space between a respective adjacent pair of strips. Also, the apertures 42c in the rearwardly declining forward panel 370 are each located opposite to and facing toward a respective inter-strip space, its adjacent pad 84, and a respective one of the notches 89 in the lateral ridge 88. As the flap 450 is secured to the bottom wall 210, it will be apparent that the section 350 will provide a firm upstanding front wall on the bottom wall, and that the forward panel 370 will be firmly held in its rearward declining relation. Of course, the side extensions and flaps 26, 27, 3t) and 31 may be folded upwards and inwards as in the previously described forms of the invention.
The instant embodiment is particularly well-adapted for a type of hypodermic needle 63c having a reduced portion or neck 95 formed in its cylinder 640, so that the neck is received in a notch 89 of the ridge 88 to prevent forward and rearward shifting movement of the article. Further, the distal end portion of each hypodermic needle cylinder 640 is received beneath the ledge 51c extending there below between an adjacent pair of strips 570 and resting on the adjacent pad 84. As best seen in Figure 19, the strips 570 serve to separate and prevent contact between adjacent articles 63c. Further, the strips 570, by their oblique disposition and inherent resiliency, serve to snugly, but not tightly, retain the article cylinder 64c in the illustrated position. That is, one strip 57c of each adjacent pair resiliently engages along its rearward edge with the intermediate cylinder 64c, and the other strip of the particlar pair engages along its forward edge with the cylinder, so that the latter is effectively but yieldably maintained in a desired position against the forces of shock and vibration, without resisting intentional withdrawal.
The needle end 660 of each article 630 is received in a respective one of the apertures 42c, and may rest on the inner, rearward edge of the latter below the associated projection 85. In this manner, the projections define detents or holding mean which effectively prevent inadvertent elevation and withdrawal ofv the needles 66c from the apertures 420, but which are readily dis- I placeable to permit quick and easy manual withdrawal of the needle from the aperture. 7

are well adapted to meet practical conditions of manufacture, storage, filling and use.
