14 Claims. (Ci. 20645.19)

Thisinvention relates to paperboard cartons, and it has particular reference to a carton for use in the packaging of incandescent lamps in such a manner as initially to afford an assembly of the lamps with the flat-folded carton which will present their bases in position for testing purposes, and ultimately, as after such testing, and squaring-up or erecting of the carton from its flat-folded condition, to enclose the lamps for handling, shipment, storage, display and sale.

One of the objects of the invention is to provide a carton which will furnish a display package for miniature incandescent lamps of the type used as Christmas lights so that such lamps may be available for shelf display in packages of appropriate multiples; and in order that no imperfect lamps will be included in the packages the carton is so formed that after the lamps are assembled with it their bases will project in position for testing prior to completion of the packaging operation whereby substitutions of lamps may be made where necessary or the partially completed package of the multiple of lamps discarded, at least temporarily, from the production line.

Another object of the invention is to provide a carton of the type referred to which is erectable from flat-folded to squared-up condition while the lamps are assembled with it, and which, after such erection, will enclose the lamps in proper relation, and in injury-resistant retention, for handling, shipment, storage, display and sale.

A further object is to provide a carton of this type in which one of its wall panels is furnished with a window opening through which the assembled, packaged lamps will be displayed.

Another object is to provide a carton of this type which is formed from a single, integral blank of paperboard material which may be folded to flat form, with chosen parts adhesively secured, by simple and inexpensive procedures of well recognized efiiciency.

With these-and other objects in view, as will appear hereinafter, the invention is directed to a carton which, in the interest of simplicity, economy, ease of handling and functional adequacy, is preferably in the form of an openended tube comprising a single, integral blank of paperboard material provided with cuts and folding scores to define therein a front wall panel, a rear wall panel and top and bottom edge wall panels, such blank being fiatfolded upon two of its folding scores and adhesively secured in tube form so that portions of at least two of its wall panels are in juxtaposition, substantially registering lamp base receiving apertures in such juxtaposed portions in which the lamps to be packaged are accommodated in projection through the fiat-folded blank for testing purposes, a window opening in said front wall panel through which the lamps are displayed in the ultimately erected carton, and preferably means adjacent to such window opening for engagement with the base-opposite tips of the lamps to hold them erect within the set-up carton; the carton, with the lamps assembled therewith in. its fiat-folded condition, being erectable to set-up package form by a simple manipulation of the carton parts, all as will be explained hereinafter more particularly and finally claimed.

Fig. 21 is a rear perspective View of the carton of Fig. 20.

As will be apparent particularly from the showing of It will be noted, moreover, that the cartons of individual blanks are, as shown, designed for the packaging of five lamps, which is in accordance with a preferred merchandising practice.

Furthermore, especially in the case of miniature lamps of the smaller sizes, it may be desired to present them for sale in multiples of ten at the option of the purchaser, and to this end the cartons may be furnished as split cartons each of which comprises two of the individual five-lamp cartons joined along, and optionally capable of being separated, or split, upon an intervening cut score line, as indicated by the showing of Figs. 9 to 11.

Obviously, also, the cartons may be designed for the packaging of lamps in multiples of other than five lamps, or for the packaging of individual lamps, and by the split carton arrangement packages of various desired multiples of lamps may be presented for sale as unit packages.

The blank of the carton of Figs. 1 to 8 shown particularly in Figs. 1 to 3 as being one of a longitudinal plurality or multiple thereof separated from its longitudinally adjacent similar blanks by spaced cut-scores 1, comprises, seriatim, a top edge wall panel 2, a front wall panel 3, a bottom edge wall panel 4, a rear wall panel 5, and a glue flap 6, these elements of the blank being defined by its free edges 8 and 9 and, intermediately, by folding

scores

10, 11, 12 and 13.

The front wall panel 3 is provided adjacent to its ends with similar cuts 14, preferably of arcuate shape for a purpose hereinafter explained, to provide a window opening, and the material of the blank within the window opening is cut longitudinally, as indicated at 15 to form therefrom a lamp supporting shelf member 16 hinged upon a folding score 17 and a retaining flap 18 hinged upon the folding score between the top edge wall panel 2 and the front wall panel 3.

The shelf member 16 is provided with a longitudinal series of apertures 19 of a size to receive and preferably frictionally engage the through-projected bases of the lamps to be packaged, and theapertures are so relatively spaced as to hold the packaged lamp out of possible contact with each other.

The retaining flap 18 is provided with notches 20 equal in number to and axially aligned with the apertures 19 of the shelf member and serving, in the completed package, to engage and properly position the tips of the packaged lamps. Those portions of the cut which extend across the notches of the retaining flap 18 are offset from the balance of the cut 15 to furnish upon the free edge of the shelf member off-standing lugs 21 for engagement with the rear wall panel 5 when the carton is in its erected, square-up condition.

The rear wall panel 5 is provided with a plurality of apertures 22 so located that when the carton blank is fiat-folded to tube form, Figs. 2 and 3, with the top edge wall panel adhesively joined to the glue flap 6, they will substantially register with the apertures 19 of the shelf member 16 of the front wall panel 3, Fig. 3.

Considering the blank of Fig. 1 to be shown as presenting its inner face, the folding and securing of it in tube form, as viewed particularly in Fig. 3, is accomplished by folding the rear wall panel 5, with its attached glue flap 6, upwardly upon the folding score 12 and then downwardly so that it lies flat over the bottom edge wall panel 4 and a portion of the front wall panel 3. Then, with glue applied to the glueflap 6, preferably prior to its folding with the rear wall panel 5, the top edge wall panel 2 is folded over upon it on the folding score 10 and adhesively afiixed to it by the applied glue.

As shown in Fig. 4, a plurality of the lamps L to be packaged may have their bases L' inserted through, and frictionally gripped in, the apertures 19 of the shelf member 16, and, inasmuch as these lamps are thus assembled while thecarton is in flat-folded condition, their bases will extend through the mating, substantially registering apertures 22 in the rear wall panel 5, and will project below such panel sufficiently to permit their engagement with, or by, testing apparatus, so that, while the carton is flatfolded, any defective lamps may be detected and replaced with perfect ones.

After appropriate testing of the lamps the carton will be squared up to its fully erected condition by application of pressure at the edge folds of the

folding scores

10 and 12, bending inwardly and downwardly of the shelf member 16 and bending inwardly of the retaining flap 18.

During the initial erecting step, by application of pressure on the

opposite fold lines

10 and 12, the front wall panel 3 will be moved away from the rear wall panel 5 with a parallel motion guided by the top and bottom

edge wall panels

2 and 4 which form two sides of the parallelogram of the four carton wall panels, and during this motion the bases L of the lamps L, moving with the shelf member 16 will be drawn outwardly through the apertures 22 of the rear wall panel 5. Inasmuch as the relative movement of the front and

rear wall panels

3 and 5, guided as sides of a parallelogram by the top and bottom

edge wall panels

2 and 4, entails a relative displacement of the

apertures

19 and 22 of the front and rear wall panels, and as the lamps are relatively fixedly carried by the shelf member 16 in relation substantially normal thereto, the apertures 22 of the rear wall panel are preferably made sufficiently large, and larger than the apertures 19 of the shelf member 16, to permit this movement of the lamp bases through them without obstruction' by, or foulingupon, their edges. This is clearly illustrated in Fig. 5.

As shown in Fig. 6, when the group of lamps L is pivoted inwardly of the squared-up carton along with their mounting shelf member 16, their tips will ride under the retaining flap 18 and will, when the shelf member is bent downward sufficiently, move into snap engagement with the walls of the notches 20 of this flap. Meanwhile, the inward and downward bending of the shelf member 16 will bring its lugs 21 into engagement with the inner face of the rear wall panel 5, and as the dimension of the shelf member from its hinge fold at 17 to the outer edges of its lugs 21 is substantially equal to the inner dimension of the top and bottom

edge wall panels

2 and 4 between the inner faces of the front and

rear wall panels

3 and 5, the free edges of the lugs of the shelf member will somewhat frictionally engage the inner face of the rear wall panel to hold the shelf member in proper horizontal position and also to aid in retaining the carton in squared-up, erected condition.

if desired, the lugs 21 may be omitted from the free edge of the shelf member 16, and this, obviously, will not impair the proper packaging characteristics of the carton, particularly when the diameter of the bulbs of the lamps is such that the front-to-rear dimension of the shelf member, without lugs, will be sufiicient to span the distance between the inner faces of the front and rear wall panels of the carton.

In the modified embodiment of the invention shown in Figs. 9 to 12 the blank, which may be of dual form, comprises, seriatim, a front wall panel 23, a top edge wall panel 24, a rear wall panel 25, a bottom edge wall panel 26, an auxiliary front wall member 27, a shelf member 28, and a positioning flap 29, and these elements are rclatrvely foldable upon

folding scores

30, 31, 32, 33, 34 and 35. The front wall panel is provided with a window openmg defined by longitudinally spaced side borders 36, a lower border defined by an edge 37 and an upper border defined by the folding score 30 between the front wall panel 23 and the top edge wall panel 24 and provided with a retaining flap 38 for the same purpose as, and provided with notches 39 similar to, the retaining flap 18 of the form of carton illustrated in Figs. 1 to 8.

The shelf member 28 is provided with a series of lamp base receiving apertures 40, and portions of the rear wall panel and the bottom edge wall panel 26 are provided with apertures 41 which, when the blank is properly flat-folded to tube form, will substantially register with the apertures of the shelf member 28.

Flat-folding of this form of blank to tube form is accomplished by first folding, as a unit, the positioning flap 2 9, shelf member 23 and auxiliary front wall member 27 upon the folding score 33 lying between such auxiliary front wall member and the bottom edge wall panel, and preferably adhesively affixing the positioning flap 29 to the underly ng Portion of the rear wall panel 25, see Fig. 10. Then the front wall panel 23 and the top edge wall panel 24 are folded, as a unit, upon the folding score 31 between the rear wall panel 25 and the top edge wall panel 24, so that, as shown in Fig. 11, the free edge portion of the front wall panel 23 will overlie, and may be adhesively afiixed to, the auxiliary front Wall member 27.

The flat folded blank of this carton, Fig. 11, may have a plurality of lamps positioned in the apertures 40 of its shelf member 28 with their bases extending therethrough and through the underlying registering openings 41 formed in the juxtaposed wall portions of the carton so that they may be tested as hereinbefore described.

When this carton is squared-up to erected form with the complement of lamps carried by its shelf member 28, it will be apparent that, due to the connection of the auxiliary'front wall member 27 with the front wall panel 23, and the connection of the positioning flap 29 with the rear wall panel 25, the shelf member 28, and with it the complement of lamps, will be moved automatically to it proper packaging position to bring the lamps within the confines of the carton, and while the carton is thus being erected, the retaining flap 38 will be folded inwardly upon its folding score 30 so that as the lamps are rotated with the shelf member 28 their tips may be caused to engage with the notches 39 of the retaining flap, all as indicated in Fig. 12. If desired, the positioning flap 29 need not be adhesively aflixed to the rear wall panel 25, in which case it can be caused to act as a frictonal positioning member after the carton is erected, and its parts adjusted, much in the manner as described with relation to the carton of Figs. 1 to 8.

In the modified embodiment of the invention shown in Figs. 13 to 17 the relative locations of the glue flap 42, front wall panel 43, bottom edge wall panel 44, rear wall panel 45, and top edge Wall panel 46 are altered from the arrangementof these parts in Figs. 1 to 8 so that the apertures 47 of the rear wall panel which substantially register with the lamp carrying apertures 48 of the shelf member 49 are located, in the squared-up carton, adjacent to its bottom edge rather than to its top edge. Also, portions 50 of the front wall panel which are cut from the retaining flap 51 to provide the desired lamp tip-engaging notches therein are left attached to the free edge of the shelf member 49 so as to be bendable with respect thereto upon folding scores 52 for frictional engagement with the rear wall panel 45 when the carton is squared up, as shown in Fig. 16.

The modified embodiment of the carton of the invention shown in Figs. 18 to 21 is formed from a blank which embodies characteristics of the forms illustrated in Figs. 1 to 8 and Figs. 13 to 17, respectively, but differs from both of these forms. Although the registering openings 53 areso formed in a portion of the rear wall panel 54 as to lie adjacent to the top edge wall panel 55, in much the same arrangement as that of Figs. 1 to 8, and the shelf member 56 and retaining flap 57 are quite similar to those of Figs. 1 to 8, the glue flap 58 is attached to the front wall panel 59 at its bottom edge rather than at its top edge as it is shown in Figs. 13 to 17, and is affixed to the bottom edge wall panel 60.

These differences although not vital will, in some instances, make possible production of a carton having the characteristic properties of the invention which is better adapted to the packaging of particular types of lamps, than is the carton illustrated in either Figs. 1 to 8 or in Figs. 13 to 17.

It will be apparent from the foregoing disclosure that the carton of the invention may take a variety of forms,

particularly as regards the carton blank and its arrangement of panel elements and their mode of connection in flat-folded tubular arrangement, but in all forms provision is made for so assembling a complement of lamps with the flat-folded blank that their bases are suitably exposed for test purposes prior to completion of the package by erection of the flat-folded blank to squaredup, lamp enclosing, condition.

Moreover, in all of its forms the carton may be erected by a simple manipulation of its parts while the lamps which are ultimately enclosed are carried by the shelf member, and when its erection is completed the lamps will be attractively displayed at the window opening of the front panel and will be supported by the shelf member and retaining flap in such proper spaced relation as to guard them against breakage during shipment, storage, display and handling. Also, the dimensions of the carton, having reference to a particular type and size of lamps to be packaged therein, are such as to reduce possible play of the lamps within the carton to a minimum, thus further guarding against breakage and at the same time accomplishing a saving in paperboard stock and economy in shipping, storage and display space.

In furtherance of the saving in paperboard stock it will be noted that, informing the end borders of the window opening by arcuate cuts, provision is made for adequate display of the lamps at the ends of the packaged rows, while at the same time reducing the overall length of the carton and also furnishing a relatively long connecti-on between the ends of these cuts and the longitudinally outstanding portions of the front panel, and this is of particular advantage at the ends of the cuts which join the top edge folding score of the front wall panel as it tends to avoid tearing and buckling along this folding score at these portions, particularly during erection of the lamp-loaded, flat-folded blank to squaredup condition. y

A further advantage of the carton of the invention is that all of its elements, including the lamp receiving and supporting shelf member, are formed from a single, integral blank, and that this blank may be folded and glued in accordance with simple and well-known practices and by machinery of known types.

It Will be appreciated, moreover, that the one-piece construction of the carton is advantageous to the packager in that, after the fiat-folded blank is loaded with its complement of lamps, it may be handled as a unit to thus provide an economy in packaging time and expense.

Various changes and modifications are considered to be within the principle of the invention and the scope of the following claims.
