United States Patent O 3,465,871 MISSILE PLASTIC CONTAINER Charles E.- Lyons and Donald M. McDaniel, Guntersvlle, and Jack R. Wade, Jr., Decatur, Ala., assignors to the United States of America as represented by the Secretary of the Army Filed May 6, 1968, Ser. No. 726,894 Int. Cl. F42b 37/00, 39/00; B65d 85/30 U.S. Cl. 206-3 9 Claims ABSTRACT F THE DISCLOSURE An improved transportation and storage container for a missile or projectile, made entirely of closed-cell plastic material and including two identical outer halves adapted to be supported by banding when meshed together, a scalable inner container, and a suspension media for supporting the inner container. The breech end of the inner container extends out into a hollow portion between the two outer halves and is adapted for receiving an air and moisture proof closure cap.

DEDICATORY CLAUSE The invention described herein may be manufactured, used, and licensed by or for the Government for governmental purposes without the payment to us of any royalty thereon.

BACKGROUND OF THE INVENTION This invention is in the eld of missile and projectile containers. The previous containers utilized exterior strapping and fastener hardware with the missile or projectile being rigidly displaced inside the container, or if a suspension system was used, the system used shock mitigating devices such as rubber shock mounts, shock absorbers and springs.

SUMMARY OF THE INVENTION This invention is an improved transportation and storage container for a missile or projectile having a scalable inner container, a suspension media and an outer structure with banding equipment for D rings. The suspension media is made of a foam plastic material of low density that is more economical than the suspension system utilized in existing containers. The suspension media is a series of polyethylene foam plastic saddles surrounding the inner container at regular dimensioned intervals. This invention differs from other containers because it is not necessary to utilize fastener devices. The outer structure case comprises two identical open sections made of medium density polystyrene foam plastic material such that when the two sections are mated, raised ribs and recesses combine to mesh the two outer structure cases together. A threaded removable closure cap fastens on exterior threads at the breech end of the inner container and seals against an O ring. The inner container is made of high density plastic such as linear polyethylene material and is impervious to moisture. This invention provides a new packaging technique that will :be applicable to small and medium-style missiles and any other small units that have the same packaging requirements.

An object of this invention is to provide a new container which will permit access to the missile contained in the inner container without removal of exterior strapping and fastener hardware.

Another object of this invention is to provide a new and improved container capable of protecting a delicate object contained therein from severe shock and vibration during handling, transportation, and field replenishment phases.

3,465,871 Patented Sept. 9, 1969 ICC Another object of this invention is to provide a new container which will prevent the inner container O ring seal from sustaining shock forces each time the container is dropped or receives rough handling.

Another object of this invention is to provide a new high-strength, low-weight, low-cost container which will provide physical and mechanical protection during worldwide distribution.

Another object of this invention is to provide a new container comprised of only eight major components, thereby reducing the inventory of container components in the military supply system.

Another object of t-his invention is to provide an expendable container which offers the military a secondary usage through flotation capabilities inherent in the container materials and design.

Other objects and many of the attendant advantages of this invention will be readily appreciated as the same becomes :better understood by reference to the following detailed description when considered in connection with the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIGURE l is a longitudinal view, partly in section, looking at the inner container tube portion and one of two missile outer structure cases, and showing the closure cap in section that closes over the breech end of the inner container tube,

FIGURE 2 is a sectional view taken along line 2-2 of FIGURE 1,

FIGURE 3 is a sectional view taken along line 3-3 of FIGURE 1 with the other half of the missile container included, and

FIGURE 4 is a sectional view along line 4-4 of FIG- URE l.

DESCRIPTION OF THE PREFERRED EMBODIMENT FIGURE l illustrates one of two identical outer structure cases 10 of the missile container, along with an inner container 12, which holds the missile. Each outer structure case 10 -has a cavity 11 with recesses 25 therein. A threaded removable closure cap 16 is shown in section, threaded on the exterior surface of the missile-breech end of inner container 12 for holding the missile in the container. Precompressed polyethylene packing 18, on the inside of closure cap 16, holds the missile firmly within the inner container 12 when the closure cap is threaded securely on the inner container. A silicone O ring 20 fits in a groove of inner container 12 and, when secured in place by removable closure cap 16, prevents the entry of water into the inner container. An embossed handle 22 on the outer part of removable closure cap 16 aids in securing or removing the closure cap on the inner container 12. By using the embossed handle 22, the process of opening closure cap 16 from the inner container 12, removing a missile, reinserting a missile and closing the container is done in a maximum period of 4S seconds.

A suspension media consists of a series of low density polyethylene foam plastic saddles 24, that are seated in recesses 25, surround inner container 12 at dimensioned intervals. Integral polyethylene collars 14 projecting around the periphery of inner container 12, that is made of linear polyethylene, are embedded in suspension media saddles 24 to allow inner container 12 to move, as required, When the package sustains vibration excitation and shock impacts. The suspension media is designed to mitigate shock forces and vibration within limitations imposed by the missile design. The two outer structure cases 10 are composed of medium density polystyrene foam plastic which encapsulates the suspension media and the inner container 12. Banding 29, applied girthwise around the two outer structure cases reinforces the outer structure. D rings 31, attached to the banding, facilitates personnel handling or tie-down points for transportation.

FIGURES 2, 3 and 4 represent sections taken along lines 2 2, 3 3 and 4 4 respectively in FIGURE l. FIGURE 2 illustrates a traverse section of the missile plastic container showing only one-half of outer structure case 10 with one side having raised rib 26 and the other side having a recess 28 for locking with another identical outer structure case 10. FIGURE 3 illustrates a traverse section of the missile plastic container showing both outer structure cases 10 with raised and recess

26 and 28 mated to each other. The two outer structure cases encircle expanded polyethylene foam saddle section 24, which in turn encircles inner container 12 for holding the missile. FIGURE 4 illustrates a longitudinal section along line 4 4 of FIGURE l and shows the spacing of expanded polyethylene foam saddle sections 24 located inside outer structure case 10. v

Obviously, many modifications and variations of the present invention are possible in the light of the above teachings.
