Union Radio Corporat poration of lDelaware Pa., assignor to National ion, Newark, N. J., a cor- Application June i, 1944, Serial No. 538,274- 4 Claims. (Cl. 229-6) relates' to a carton depackaging of cathode The present invention signed primarily for the ray tubes. l

Tubes of that character have an envelope the geometry of which includes an extended neck portion, an adjoining enlarged conically shaped portion, and a top or screen portion. Because of this' variation in tube diameters, it is necessary to provide a form to give support to the tube at several points of contact of diderent diameters, and hold the tube in proper axial alignment to prevent breakage during the shipping and storage thereof.

In my copencling applications, Serial Numbers 500,467, and 507,672, liled August 30, 1943, and @ctober 26, i943, respectively, I have disclosed several constructions of cathode ray tube cartons embodying the general construction of multipoint suspension. provement of this constructional feature.

An object of the present invention is the provision of a carton consisting of an outer container having an inner ill-ler member adapted to afford multipoint suspension, of such a character. that the suspending means also furnishes locking means for positioning and holding theV contained tube rmly in position.

Another object is the provision of a ller member stamped from a single blank piece of paperboard, which blank is suitably scored to provide a transverse supporting platform having reinforcing members each designed lto form a tuck when reversely folded, said tucks having cut-out supporting portions along the folds and the free end of each tuck extendingi sufficiently rearwardly to abut against the opposing side wall of the'outer container.

Another object of the invention is the provi-4 sion of a filler having Wing members integrally :formed with a supporting platform, which members arev adapted to serve as supplemental supporting means for the tube and also function as resilient means in supporting the end closure members in such a manner that it is'unnecessary to use any sort of packing material between the i top or screen portion of the tube and the closure members.

Other objects, such as simplification of construction, economy of material vand reduction in time required for the packaging operation'will manifest themselves as the description proceeds.

Referring to the accompanying drawing:

' diagonal portion. I

carton; and

Fig. 6 ls a vertical cross-sectional view of a completely assembled package including a cathode ray tube supported therein, the tube being shown in elevation.

The carton illustrated may comprise an outer l. container I Vhaving side walls 2 and cut-out closing end flaps 3, the general contour of the container being tubular. An inner supporting ller member referred to generally by the reference character 4 is of a telescopic form 'and may comprise a one-piece blank 5 of paperboard, such as corrugated board. The blank 5 is provided with score lines 6 which form corners in bending and the spacing of the lines 6 is such as to Vform sections having diierent functions. For

example, section l comprises a supporting side Wall extending substantially the full length of the container I. It is, of course, appreciated that the width of the blank 5 is substantially equal to one of the inside dimensions of the outside con` tainer I, which is customarilyvsquare in crosssection. Regardless of the cross-sectional shape of the container l, the various sections, formed by folding the blank 5 along the score lines, are equal in length to the design of the carton, with respect to the geometry of the article packaged.

Succeeding the Supporting wall l is a transverse supporting platform 8 provided with a circular aperture 9, the center of which coincides with the longitudinal axis of the container Following the platform 8 is a spacing member- Il. It will be observed that the width of the transverse supporting platform 8 is the same as the inner Width of the container I, and when the spacing section l is folded along its upper score line, it depends downwardly a distance sufficient to aiordproper spacing for the succeeding section l2, which constitutes an oblique or prefer to make the angle of inclination of the diagonal member I2 substantially. 45 degrees or slightly thereunder, because The diagonal section I2 has an oblong or elliptiv cal aperture I3.4 It will be noted that the minor axis of the elliptical aperture corresponds to the diameter of the neck of the cathode ray tube I4 and the apertures 9 and I3 have a common axis Awhen the illler member 4 is telescoped within the container l.

In order to strengthen the diagonal member I2, each of the outer edges thereof is provided with a wing I5,. adapted to fold downwardly to afford reinforcement to the diagonal section I2. To augment the reinforcing effect of the wing members I5, the edges thereof are cut atan angle so as to abut against the inner side wall of the container I (see Fig. 2). l

Adjoining the diagonal section I2 is another spacing section I6. The width of the spacing section I6 is such that when ltjis folded along the score lines 6, it will produce a corner for trans- `verse section I 1, which corner rests on the bottom ing the wings I8 are of suillcient width that when the wings I3 are folded into a tuck, the sections 2l are inclined upwardly and engage the inner corner of the adjacent end closure iiaps 3. When the end aps 3 are folded downwardly, closing the outer container I, the abutting edges of the sections 2I constitute a exible anchorage, the eect of which is to exert an appreciable downward pressure so that an element of resiliency is/ imparted to thewingmembers I8 and the tube I4 is thus resiliently, but ilrmly, supported within the carton.

To facilitate the removal of the tube I4 from the carton, I provide the expedient of cut-out apertures along the outer edge of the sections 2|. By inserting ones ngers into the apertures 25, it is a simple operation to pull up the wing sections I8, thereby affording easy access to the tube.

From the foregoing.description, it is obvious that the tube- I4 is supported at a number of points so that the weight thereof is distributed among multiple points of suspension, thus relieving anyr v excessive strains that might occur if the suspen- The wings I8 are provided with score lines I9 which divide each of the wings I8 into longitudinal sections 20 and 2I of substantially equal width so that when sections 20.and 2l are reversely 0f the tube I4 When the latter is inserted in the ller 4, as hereinafter more fully explained. In making the apertures 22, I prefer to retain the cut-out portions to form tabs 23v which are hinged along the score lines I9. This may easily be done by not extending the die-cut beyond the score line When the'iiller member 4 is folded for insertion into the outer container I, it takes the form or shape shown particularly in Fig. 2. Thus folded,

it is set into the outer container (see Fig. 3) and while in that position, the tube I4 may be inserted so that the neck portion of the tube extends through the elliptical aperture I3, and the upper conical portion of the tube comes into engageed out as constituting the engaging elliptical aperture I3, the circular aperture 9, and the semi-circular apertures 22. The downward cantilever action, applied by sections'2I anchored against ,l

the inside corners of the closure flaps 3, resist any displacement of the tube I4 that may be caused fby an upward movement, occasioned for example by the cartons being set upsidedown with respect .to the way the tube is packaged.

To those skilled in the art, it will be appremated that m the packaging or cathode ray vtutti;

the prongsat thev base of the tube should at all times be out or contact with the bottom or the ment with the circular aperture 9. In this position, the tube may be used as means for pressing the filler 4 all the way into the outer container I (see Fig. 4). At this stage of the packing operation, the wings I8 are each folded along the score lines I9 with the result that tucks areformed.-

the edges of which slightly extend beyond the perimetenofthe top ofA the tube I4 so that the apertures 22 engage with the opposing portions of the perimeter and form points of support for the tube (see Fig. 6).

As indicated abov'e, the sections 20 and'2l formcarton, because when the prongs do come in contact with th'e bottom, the glass seal surrounding the collar portion of the base is very apt to be- -come cracked, which leadsto defects destroying the emciency and/ or life of the tube. t 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 modiwithin the scope of the appended of a one-piece scored Iblank adapted to form a.

series of sections when folded along the score lines, one of said sections constituting a trans- It is obvious that the tabs 23 are pushed upwardly and rearwardly by the^en verse supportingplatform having laterally extending wing sections provided with score lines adapted tol form a tuck when the wing sections are reversely folded with respect to the supportplatforms, segmental die-cut portions arranged -with an edgev thereof hinged on said score lines and adapted to form tabs extending laterally from the apex of the tuck, apertures based upon the score lines of the wing sections and resulting from the formation of said tabs. said vapertures constituting supporting means for the inserted- `top edge of a cathode ray tube, and the tabs affording supplemental locking means for holding the tube in proper alignment within the carton.

2. The construction claimed in. claim 1. 'wherein the wing sections of the supporting platform u e,a7v;eo4

are provided with score lines which divide them into' portions of substantially equal width when folded into a tuck, the apex of said tuck extending to a supporting position for the top edge of the tube and the free end of the-upper tuck portion abutting against the inner corner of the adjacent end closure flaps of the outside container, whereby the tube is resilently anchored against longitudinal displacement.

A carton for cathode ray tubes comprising an outer container member having side walls and cut-out closing end iiaps, aninner supporting filler member of a telescopic form and consisting oi a one-piece scored blank adapted to form a series of sections when folded along the score lines, one of said sections constituting a transverse supporting platform having laterally extending wing sections scored longitudinally and adapted to form a tuck when reversely folded with respect to tuting supporting means for the inserted topA edge of a cathode ray tube, and the tabs affording supplemental locking means for holding the tube in proper alignment within the carton.

4. I'he construction claimed in claim 3, wherein the apexes of the tucks are oppositely disposed with respect to each other, and the free end of the upper portion of each tuck abuts against the inner corner of the adjacent end closure iiap of the outer container, whereby the tube is resiliently anchored against vlongitudinal displacement.
