Application June 21,

9 Claims.

This invention relates to certain new and useful improvements in cartons for radio tubes and the like, the object being to provide a carton with means for resiliently supporting a radio tube therein in such a manner that it can move longitudinally in order to project one end thereof outwardly in order to test the tube and yet the tube is permanently locked within the carton so that it cannot be removed without destroying the carton, thereby preventing bootlegging of an inferior product and the unauthorized packing of such product.

Another object of my invention is to provide a carton which is formed from a; single blank to provide a tubular casing having integral end closures provided with self-locking tongues and integral partitions for supporting the radio tube whereby the carton can be manufactured cheap ly, the partitions being so constructed and connected to one wall of the casing by flaps that resilient means is provided for supporting the tube, the partitions being adapted to be bowed ,in order to resiliently support the tube whereby the tube will have a tendency to return to its original position after the end has been forced outwardly to test the same.

Another object of my invention is to provide a novel construction for locln'ng the end closures after the tube has been placed in position within the container without the use of glue or separable fastening means, whereby the cost of manufacturing the container is greatly reduced and a positive lock is provided for the end closures to prevent the tube from being removed without destroying the container.

Other and further objects andadvantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings,

Figure 1 is a perspective view of a container constructed in accordance with my invention;

Figure 2 is a longitudinal section showing the radio tube in dotted lines in its normal position; Figure 3 is an enlarged longitudinal section showing the radio tube extended in position to be tested;

Figure 4 is a section on line 4-8 of Figure 2; Figure 5 is a detail perspective view showing the locking tongue before it has been inserted within the slot of the wall of the container; Figure 6 is a detail perspective view showing the locking flaps of the tongue bent in position to be forced through the slot in the wall of the containe and V 1935, Serial No. 27,808

Figure '7 is a plan view of the blank from which the carton is formed.

In carrying out my invention, I form the complete carton from a single blank of cardboard or other suitable material, which comprises a tubular casing formed of side walls I, 2, 3 and 4, the wall 4 being provided with a flap 5 which is adapted to be secured to the inner face of the wall l by any suitable adhesive material, the, flap being formedby a score as shown in dotted lines. Formed integral with the wall 3 of the tubular container at each end are end closures 6 and 1 which are scored as shown to provide side flaps 6' and I and locking tongues 8 and 9, the locking tongues 8 and 9 being scored as shown by dotted lines to provide resilient looking ears 8' and 9, forming substantially T- shaped heads, these locking tongues and ears being adapted to be bent into the position shown in Figure 6 and forced through slots l0 formed in the wall I of the tubular casing in order to lock the closures in closed position as will be hereinafter more fully described.

The end closures 6 and I are provided with opening 6 and 1 opening 6 being for the purpose of allowing a finger or thumb to be inserted in order to force, as for example, a radio tube ll outwardly through the opening 1 in order to allow it to be tested as clearly shown in Figure 3.

Formed integral with the ends of the wall I of the tubular container are tube supporting members 12 and [3 which are scored on the dotted lines to produce partitions l4 and I5, connecting flaps l6, and I9.

The tubular container formed by the side walls I, 2, 3 and 4 is preferably rectangular in shape and can be formed of any suitable material, such as pasteboard and the like. After the flap 5 has been cemented to the wall I, the tube supportling members l2 and I3 are forced inwardly through the open ends of the tubular container into the position shown in Figure 2 and the size of the partitions I4 and I5 is such that they are bowed as clearly shown, it, of course, being understood that the radio tube II is placed in position within the carton within the partition 15 before the partition I4 is forced into position. When the partition [4 is forced into position, the end of the tube extends into the opening l, the other end of the tube being seated in the opening I5 of the partition l5 and as both of i1 and I1 and guide flaps l8 these partitions are of a greater size than the inner size of the container, they bow when port the tube H whereby when the tube is in its normal position as shown in Figure 2 andis forced outwardly to test the'same into the position shown in Figure 3, the partition bends so that the bow is in the opposite direction and as the cardboard is flexible, it has the tendency to return to its original position when pressure is removed'from the same so as to return the radio tube into its normal position. 10-

The connecting flaps i6, i6, H and H of the partitions id and i assume the position shown in Figures 2 and 3 when forced into position within the container in order to provide pockets 2d and 26 to protect the locking tongues 8 and 9 when in locked position, whereby it is impossible to insert an instrument of any kind into the carton and manipulate the ears 8 and d of the locking tongues t and 9 in, order to release the same and to allow the closure members to be opened whereby a positive lock is provided which, when once inserted into locked position, closes the ends of the carton and permanently locks the radio tube therein so that it is impossible to remove the same without destroying the carton.

Assuming that the radio tube has been placed in position within the carton within the resilient supporting means, the ears $3 of the locking tongue 8, as for example, are bent back upon the tongue into the position shown in Figure 6 and forced through one of the openings it and as the material from which the tongue is formed is flexible, the ears of the tongues spread outwardly after passing through the opening so as to positively and permanently lock the closure in closed position. It is, 'of course, understood that the opposite end closure is secured in a like manner and the radio tube will now be packed in a carton so as to thoroughly protect the same in shipment and yet allow the same to move therein so that one end can be projected outwardly in order to test the same and as the partitions are flexible, it not only resiliently sup-' ports the radio tube, but has the tendency to return the tube to its normal position within the container after being forced outwardly to test the same. I

While in the drawings and specification I have shown and described a carbon especially designed for the merchandising of radio tubes, it is, of course, understood that the same can be used for merchandising electric light bulbs or any other objects which are generally tested to determine their condition prior to sale.

From the foregoing description it will be seen that I have provided acarton with resilient partitions resiliently supported within the container for supporting a radio tube resiliently to enable one end of the tube to be forced out of thecontainer in order to allow the same to be tested and when released, will return to its normal position by the resiliency of the supporting means and partition.
