Lansd aie, 2a., asslgnor to National Union Radio corporation, Newark, N. 1., a corporation of Delaware Applicatlonfliiay 1a, 1944, Serial No. 536,091 2 Claims. (01. 229-6) 'The present invention relates to a carton designed=primari1y for the packaging of miniature radio tubes. 1

At the present time, conservation of paper is a vital necessity in the war effort, and any form of packaging which tends to save paper is encouraged by thegovernment. Furthermore, any improved. simplified form of radio tube carton is always welcomed by the industry because it effects economies in assembly which cheapens the pack- It is therefore an object of the present invention to provide a one-piece carton so designed as to reduce very substantially the amount of paperboard required for the making there'of.

Another object is to simplify the construction of a carton so that the complete carton may be stamped from a single blank piece ofpacking material die-cut and suitably scored for folding purposes. 7

Another object of the invention is the provisionof a one-piece carton which when assembled does not require stitching or gluing to hold the carton in an assembled position. a

I Another object is the. provision of a cut-out blank provided to form side walls when folded and also having laterally extending portions adapted to fold in such a manner that transverse supporting platforms are formed between which the tube may be suspended. I

- Another object of the invention is to provide a carton made from a single blank consisting of two major portions, one designed to fold into a nller member in which the tube is supported, and

' the other adapted to provide an outer wrapper portigr which folds and locks about the tiller mem a further 'obiect of the invention is the provlsion of a cardboard blank having a general body portion and a laterally formed portion contlg-.

*uous with one end of the body portion capable of a folding into a tube-supporting tiller element, and the body portion then wrapped around the filler. Other objects will manifest themselves as the descriptlonproceeds. a

Referring to the accompanying drawing:

and

Referring to the accompanying drawings, particularly Fig. 1, it will be seen that the carton is comprised of a one-piece blank designated generally by the reference character l, which blank consists of a major longitudinal wrapper portion 2 and a major filler portion 3- extending laterally 2 is provided with transverse score lines 4 dividing it into a series of sec tions- 8 to 9 adapted to constitute side walls when folded along the score lines 4, thus forming an outside wrapper for the filler el ment. The lateral body portion 3 is adapts to form a flller element for the outer wrapper comprise a wall section III which is continuous with but somewhat less in length than the side wall sections 5 to 9. Adjoining the wall section II is 8 top section II and a bottom section If. The sections II and I! are provided with die-cut apertures ll and I4 respectively, these apertures aperture ll.-the reason being that the tip portion tube is intended to prolectthrough-the lb of the a llwhile the prongs ll of the base project through the aperture ll, without permittin said aperture H (see Figs. Bio 5). It will thus be seen that the sections ii and I2 platforms for the tubewhen the nller element is formed by folding the component partsof the lot eral-body portion 3.

' wing portions it transverse portions and I: are a continuation of II and i2 respectively, said tions II and fl respectively, of sufficient length to the filler member 3.

transverse platforms wing portions 22. 13. which are adapted to lines. It will be noted it are cut out, preferably with round corners. from the main body portion 2 and are of less width than the wing extensions 12 and 24; ineferring particularly to Fig. 2, it-will that the several wing H and I: have extendin and 25, fl, respectively.

be seen rtion'and may I constitute transverse supp rtin having laterally extending side porfold along suitable score that the portions it and portions lust described are 'foldable along the edges of the transverse platfolding upwardly the l2 along their score lines 28, and when'thus foldtween the forms ii and I2 so as to constitute side walls of end closures 21 and 28 which are completed by transverse platforms II and ed, the outer edges of the wing members forming said closures abut against each other, thus-completing the filler construction (see Fig. 3). It is obvious that the wing portions 23 and 25 function primarily as reinforcing means and also facilitate the folding of the wrapper element about the filler element as will be apparent hereinafter.

The first operation in packaging the tube is to fold the various wing sections comprising the end closures 21 and 28, and as a part of this operation the tip I! of the tube is lnsertedin the aperture l3 and the prongs i I extend through the aperture It, thus between the transverse platforms II and I2 and completely enclosing it within the filler element. The wrapper is then folded around the filler by sequentially bending the successive side walls 5 to 9 along the score lines 4 which define side walls of a width to form an outer container which fits snugly against the filler element.

It will'beobserved that the width of the side walls 5 to 9 is slightly in excess of the width of the filler element so as to permit thefolding of these walls about the filler element but in snug contact therewith so that there is no space bewrapper and the filler and by this construction the two major portions 2 and l reinforce each other when the carton is assembled.

It will also be noted that the depth or location of the transverse supporting platform sections Ii and i2 is suflicient to protect the tip li and the prongs I! of the tube from end-wise exposure.

This step just described in the packaging of the tube may be regarded in the nature of a rolling operation and when the sidewalls 5 tot have been thus wrapped about the filler element they may be locked in place by any suitable fastening means. In the provided a suitable slot located preferably along one of the longitudinal edges of the side wall 6. A locking tab ll is provided on the outer edge of the side wall 9 and the tab 3|, although appreciably greater in slight manipulation on the part of the operative.

By virtue of the locking means provided for the filler element and the outer wrapper, no stitching or gluing is necessary to hold the'car'ton in an assembled position. Through the elimination of any stitching or gluing operations in pro-fabrication or during the assembly of my carton, a saving in time is effected with a consequent saving in cost. It is also apparent that by the simplicity of the construction of my carton, tedious packing operationsare eliminated, as is the case wherever an inner filler is provided that must present instance, I have width than the length of the slot is adapted to be inserted therein with length of the slot ll, when the wrapper is locked about the filler member, the tube cannot be removed from the carton without evidence of mutiv,lation of the outer wrapper. This arrangement provides a safety feature or means of indicating to the wary purchaser whether there has been any tampering or substitution 'of the tube for the one originally packaged.

Modifications in the construction of my carton will suggest themselves to those skilled in the art,

but it is my intention to cover all such modifications as come within the scope of the appending claims.

What is claimed is:

1. A carton for radio tubes and the like formed from a one piece blank consisting of a major 1ongitudinal wrapper portion and a major filler porsecurely suspending the tube, 7

tion, the wrapper portion being provided with transverse score lines dividing it into a series of sections adapted to constitute side walls when folded along the score lines, one of the end side walls forming an outer side wall of the filler portion and having laterally extending therefrom contiguous wing sections, each of the wing sections being adapted to form transverse end platforms having die-cut apertures in axial alignment and adapted to accommodate the tip and prongs respectively of the tube, said platforms being reinforced byfoldable sideand end sections contiguous with the platforms and designed to enclose the tube suspended between the apertures of the platforms, the opposite end side wall of the wrapper portion having a tab adapted to engage a slot provided along one of the longitudinal edges of the side wall adjacent to the filler portion, whereby when the filler element is folded to suspend the tube between the transverse and platforms the wrapper portion may be rolled about the loaded filler and held locked by engagement of the tab with the slot.

2. A carton for radio tubes and the like formed from a one piece blank of paperboard consisting of a major longitudinal wrapper portion and a major filler portion, the wrapper portion being foldable about the filler, member and provided with transverse score lines dividing it into a series of sections adapted to constitute side walls when folded along the score hues, one of the end side walls forming an outer side wall of the filler portion and having laterally extended'therefrom contiguous wing sections, each of said wing sections being adapted to form transverse end platforms having die-cut apertures in axial aligncontiguous with the platform and designed to be foldedseparately and inserted within some form of an outer container. That is to say, by reducing the number of parts constituting the carton the packaging of the tube is greatly facilitated. By avoiding the duplication of side walls which lemon or less inherent in a carton composed of several separate parts, a substantial saving of stock material is thus effected.

When the tab 3i has been inserted within the slot'30, it functions as a detent, and the slot 30 serves as a keeper therefor. By the simple expedient of making the tab 31 wider than h wall adjacent enclose the tube suspended between the apertures of the platforms, the side walls of the wrapper portion extending sufficiently beyond the transverse platform sections to protect the tip and prongs of thetube from endwise exposure, the opposite end side wall of the wrapper portion having a tab adapted to engage a slot provided along one of to the filler portion whereby when the filler element is folded to suspend the tube between the transverse end platforms the wrapper portion may be rolled about the loaded filler and held locked by engagement of the tab with the slot. 7 PERRY BELDEN.
