v 7 Claims. (01. 229-6) The present invention relates to a carton desied primarily for the packaging of cathode ray tubes.

Tubes of that character have special uses in apparatus employed extensively by the armed forces, and under such service conditions must meet rigid specifications with respect to the manner and/or form of carton in which they are packed. For reasons of transportation the carton must be compact, light in weight, and most important, the method of suspending the tube within the carton should include an inner supporting member of such design as is not likely to collapse by the absorption ofmoisture by the material from which said member is made; as for example, paperboard.

A iurtherrequirement of a carton adapted to contain a cathode ray tube is that the design of the inner supporting member be such as to accommodate or receive tubes having different geometry. As is well known, tubes of this type have considerable variations in bulb structures respecting length, contour and size of a given buib. This requires that the construction of the inner supporting member be adapted for such variations without substantial change in design.

it is an object of the present invention to provicle a carton having an inner supporting member adapted to aflord multiple points of suspension for the contained tube to prevent collapse of the supportingm'ember, particularly by the ab sorptlon of moisture. I

Another object of the invention is to provide an inner supporting member characterized by struc-' turai features which prevent or materially lessen the chances of the tube being damaged by lateral or transversely received blows. I

Another object of the invention is the provision of a foldable inner supporting filler that includes sections which makes it unnecessary to use any sort of packing material such as Kimpac 7" or the like, in order to protect the top ialce oi the tube from-injury and also assist in holding the tube in place when it is sealed within thecarton.

A special object is the provision of interlocking fingers on each end of the'blank'compris-ing the filler, and havingv this interlocking means so designed as to permit readyassemblywith respect to inserting the opposing fingers. 7

Other objects will manifest themselves as the description proceeds.

Referring to the accompanying drawing:

F13; 1-is an extended view ordevelopment of the blank forming the inner filler member, constituting the supporting-element of a carton embodying the invention;

Fig. 2 is a vertical cross-sectional view of a completely assembled package showing a cathode ray tube supported within the outer container;

Fig. 3 is a similar view taken on line 3-3 of Fig. 2;

Fig. 4 is a perspective view of the inner filler member folded and ready for insertion into the outer container; and

Fig. 5 is a modification of the blank shown in Fig. l.

The carton illustrated may comprise an outercontainer I having side walls 2 and cut-out closing end flaps 3, the general contour of the container being tubular. An inner supporting filler member referred to generally by the reference character 4 is of a telescopic form and may comcorrugated board. The blank 5 is provided with score lines 6 which form corners in bending and sections having different functions.

the spacing of the'score lines 6 is such. as to form For example, end flaps l1 and 8 are provided with interlocking'fingers 9 so as to provide a locking means for holding the blank assembled upon the folding thereof. This feature will be described more particularly hereinafter. Adjacent to the flap l is a section it which functions as a transverse supporting platform within the container i. The platform I0 is provided with a circular aperture H which acts as a point of suspension for the cathode ray tube I61 when inserted therein.

Adjacent to the transverse section III is a spacing section I9 which extends to the bottom. of the container l and functions as oneof the side supports. Sections i2 and I3 are adapted to,

fold in such a manner as to provide an inverted V-shaped support with the apex centrally disposed and said sections of sufficient height with respect to the container I that the portion of Section 8. adjacent to section l3, extends upwardly when the filler member 4 is telescoped within the container I to such a point that the bottom edges of the interlocking fingers 9 are in abutting engagement, with one another, thus completing a side support or wall for the tiller t and providing means for maintaining the transverse supporting'platform ill in a. horizontal position, i. e., at right angle to the side supporting walls of the container 5.

As additional supporting means there are pro.-

' vided laterally extending wings H on the outer edges of the platform l0, said wings being adaptedto fold upwardly and at an angle with respect to the platform It. The wings ll are provided with oblong apertures I8, running. longitudinally therewith and positioned relative to the top edge or perimeter of the cathode raytube so that said edge protrudes or extends slightly through the apertures 58 and thus partially supports the tube along the protruding portions thereof. It will be noted that the width of the wings I! is such that their opposing end or outer edges adjoin when the wings I! are folded into position and that the peak formed by these engaging edges of the.

wings ll constitute a support for the closing flaps t of the container I. By this arrangement the tube It is firmly pressed downwardly and in axial alignment of the container l. I

To aflord a safety feature, the outer edges of the sections l2 and is may be cut away in any suitable manner, for example, as illustrated by Fig. 5, so that when the sections it and it are telescoped within the container 8, the portions of the blank 5 immediately adjacent the opposing side walls 2 of the container l, are out of contact with said sidewalls. This arrangement thus provides a space between the cutout portions of the edges of the inverted ll-shaped support and consequently any. blow received transversely at this portion of the carton, will not be transmitted through the apex of said support to the contacting edges of the tube it as would be the case if these cut away portions were not provided and the edges of sections i2 and is-were in direct contact with the side walls 2 of the container i.

It is obvious that the shape of the cut away edges may take any form but when they are curved as illustrated in Fig. 5 the desired object may be accomplished with e. duo of weakening the strength of the filler member d et the point of suspension constituted by, the sections l2 and I3 when in folded position.

As an expedient for quickly folding the blank E5, the interlocking fingers a may be made of difierent lengths bycutting the transverse outer edge of the end flaps l and t at different glee with respect .to' each other, (See liig. 5.) By this construction the operative is enabled to more easily insert the fingered in'an interlocking relation. It will be noted that although the interlocking fingers will thus vary in length, by having the recesses of the same transverse depth, the height of the supporting wall completed by the engagement of the fingers and their bases resting on the bottoms of the recesses, the supporting platform I0 is maintained at substantially right angle to the walls of the container member.

From the foregoing description it is obvious that the tube It is supported at a number of points so that the weight of the tube is distributed among multiple points of suspension thus reliev-.'

ing any excessive strains that might occur if the suspension of the tube consisted of merely'a one from which the blank 5 is composed is not very moisture repellent, and the carton is exposed to service conditions of the armed forces, which almost inherently include exposure of the pack-:-

aged tube to all sorts of weather conditions, ab-

sorption of moisture by the filler member does not seriously adversely aifect the suspension of the tube because of the distribution of the weight of the tube among the number of points of suspension. In other words, if the tube It was supported from asingle point of suspension and the filler member absorbed substantial moisture at that point of suspension, the tendency is for the section of the blank 5 forming the point of suspension to fail so that the tube is no longer in proper alignment within the carton and thus easily subject to damage or injury from blows normally received in transportation or storage of the packaged tube.

In the foregoing description and in the claims,

' I have referred ,to' the. material from which the the material'used in making the carton, certain.

economies such as reduction in cost of manufacture. etc., are' possible.

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 modiilcations as come within the scope of the an pended claims. 4 I
