It is a still further object to provide a shipping container as above wherein a pair of shipping containers with covers thereover may be assembled with their covers in face-to-face relation to provide a compact shipping package.

Other objects and advantages will become more apparent When considered in conjunction with'the following detailed description and drawingsshowing by way of example, a preferred embodiment of this invention.

DETAILED DESCRIPTION The shipping container of this invention is adapted to carry five electron gun assemblies of the type used in color television. Referring to FIG. 1, the gun assembly includes an elongated glass tube 22 having a disc head 24 with a plurality of leads and supports 26 extending through presses 28 arranged in a circle in said head 24. These leads and supports 26 form an annulus of terminals having a diameter less than that of the disc head 24 on the tube side of said head and are connected to the gun elements, namely, the cathode, the grids and the anodes in the conventional manner. The cathode assembly, first and second grids and first and second anodes are connected to elongated supporting rods 30 to provide and insure proper positioning of the gun elements. There are three supporting rods 30 arranged in equal spacing around the periphery of the gun elements to form a generally circular outline no greater than the diameter of the disc head 24. The second anode 32 has a radiating rim 34 of a diameter generally equal to that described by the three supporting rods 30 and the disc head 24. The rim 34 supports an annular getter assembly 36 by means of a plurality of arms 38 secured thereto.

A plurality of envelope neck engaging spring legs 40 are secured and equidistantly spaced on the periphery of the rim 34 and have outwardly curved end portions 42 to engage the inner face of the conventional envelope neck. An elongated spring strip 44 is connected to the periphery of rim 34 at a point diametrically opposite one spring leg 40 and mounts a second annular getter assembly 46.

This type of electron gun assembly must necessarily be shipped in a manner such that a minimum of vibration and shock will be encountered in order to protect the large number of welded and soldered joints found in this unit. This problem is further complicated by the elongated spring strip 44 which supports the second getter assembly 46.

In view of the above, the container of this invention comprises a molded plastic base 50 of generally rectangular outline having side channels 52 and 54 adjacent the longitudinal edges 56 and 58, respectively, of the base. A first gun-receiving recessed section 60 is formed in the base 50 to conform to the overall configuration of the above described gun assembly. The first section is adjacent and generally parallel to one of the end edges 6-1 and includes an elongated slot 62 sized to accommodate the elongated tubular member 22 of the gun assembly and having its lower end terminating in side channel 52. A recess 63 extends from the upper end of the elongated slot 62 and is adapted to receive the annulus of terminals immediately adjacent the disc head 24. An elongated chamber 64 extends from the end of the aforesaid recess 63 and is adapted to contain the disc head 24, the elongated supporting rods 30, the rim 34 of the second anode 32, together With annular getter 36 and supporting springs 40. Positioning grooves 66 are formed in the forward end of the chamber 64 to receive the curved ends 42 of springs 40 so as to position the gun assembly longitudinally in the recessed section 60.

A curved channel 70 extends from the elongated chamber 64 and merges with side channel 54. This curved channel 70 is adapted to carry the elongated spring strip 44. A depression 72 in side channel 54 is provided to receive the lower portion of the second getter assembly 46 carried on elongated spring strip 44.

The recessed section 60 is provided with several additional means for positioning the gun assembly 20 therein. A protuberance 74 is formed in the forward end of chamber 64 so as to engage the upper edge of the anode rim 34 and retain the gun assembly in longitudinal position with the lower end of glass tube 22 resting in notch 76 in the outer wall of the side channel 52. Further, a pair of spaced gripping elements 78 and 79 are formed in the wall of slot 62 to grip the outer surface of glass tube 22.

Second and third gun receiving recesses 80 and are provided in the base 50 parallel to gun receiving recess 4 3, 60. Fourth and fifth gun receiving recess sections 100 and 110 are similarly shaped to 60, 80 and 90 but are reversed end-for-end to provide a more compact arrangement.

As best illustrated in FIGS. 2 and 3, the base50 is provided with a cover 112 which acts to retain the gun assemblies within-their respective recessed sections and in hermetically sealed condition. In this connection, it should be noted that the depths of the various portions of the gun receiving recess sections are of such a depth that the cover 112 will retain the gun assemblies in position in a tight and secure manner. Prior to hermetic sealing, an inert atmosphere is injected into the container so as to preserve the quality of the getter since the getter material deteriorates in normal atmosphere.

In order to provide a compact and sturdy shipping package, two of the shipping containers are positioned so that their covers are in face-to-face contact to provide a shipping package 120 as illustrated in FIG. 4 of the drawing.

There are many types of materials which may be used to produce the shipping container of this invention.-

The main requirements are that the material should be easily molded, having substantial strength and be reasonable in cost.
