Definitions

• the present invention relates to a container for sensi ⁇ tive objects, for example projectiles or missiles, com ⁇ prising mainly two container halves which when brought together define an elongated cavity which accommodates the projectile or missile, this cavity exhibiting support 0 surfaces which correspond to the configuration of the projectile and which support the projectile radially.
• the invention relates particularly, although not exclusively, to containers for projectiles intended for antitank rifles. 5
• the object of the invention is to provide a container of the kind described in the introduction which will afford much gentler deceleration in all directions, and which in the case of projectiles greatly reduces the risk of the detonating fuse of the packaged projectile being accelerated to an extent such as to arm the fuse.
• the container according to the invention takes up forces acting radially on the projectile in a known manner, through support surfaces which conform the outer con- figuration of the projectile.
• the axial forces liable to occur should the container fall or be dropped for example are taken up by a plate-like element capable of being firmly positioned in the container. It is a relatively easy matter for one skilled in the art to dimension such a plate-like element so that it will gently retard movement of the projectile should the container fall or be dropped, even from a relatively high height.
• a further plate-like element can be arranged rearwardly of the firstmentioned element in accordance with a further development of the invention, the two plate-like elements being held firmly against a respective side of one part of the container.
• Figure 1 is a perspective view of one of the two halves of the container.
• Figure 2 is a longitudinal view of the container half illustrated in Figure 1, with a schemati- cally illustrated projectile positioned firmly between two plate-like elements.
• Figures 3a and 4a are end views of the two plate-like elements shown in Figure 2.
• Figures 3b and 4b are respective cross-sectional views of the plate-like elements shown in Figures 3a and 4a.
• Figures 5a och 5b are respectively an end view and a cross- sectional view of a bayonet-coupling part of the rearward end of the projectile, the shell, indicated in Figure 2.
• Figure 1 illustrates one of two mutually identical container halves 1 made of cellular plastic or a like material, from which substantially the whole of the container is constructed.
• the cavity exhibits, inter alia, a plurality of support surfaces in the form of three ribs 3, 4 and 5, whose shape conforms to a corre ⁇ sponding cylindrical part 6 of the projectile 2.
• the projectile 2 presents a part 6a which narrows coni- cally rearwardly of the cylindrical part 6, and a part 6b which narrows conically forwardly of the cylindrical part 6 and which is provided, inter alia, with an extendable stand-off means 7.
• These parts 6a, 6b and 7 of the pro ⁇ jectile must not come into contact with the container when subjected to vibrations or when the container falls or is dropped, and are therefore left free in the con- tainer.
• the support surfaces 3, 4 and 5 are intended to take-up any forces which might act radially on the projectile during its transportation. Axial forces are taken-up with the aid of a plate-like element 8 made of aluminium or the like, the illustrated element having the form of a circular disc.
• the element 8 is received in a correspon ⁇ ding groove 9 provided in the two container halves 1.
• the grooves 9 lie in a common plane at right angles to the longitudinal axis of the projectile.
• the form given to the element 8 is shown more clearly in Figures 3a and 3b.
• the male part 11 of a bayonet-type coupling Located on the rearward end 10 of the projectile 2 is the male part 11 of a bayonet-type coupling, having four coupling shoulders 11a, as shown in more detail in
• the part 11 of the bayonet coupling is intended for securing a propellant-part (not shown) to the projectile with the aid of a female part of a corre ⁇ sponding bayonet coupling on the propellant-part.
• the coupling part 11 can be rigidly connected rearwardly (through a joint not shown) with a cylindrical part 10a (indicated in chain lines in Figures 2 and 5b), e.g. a part which incorporates means for initiating firing of the propellant-part.
• the male part 11 of the bayonet coupling can also be used to secure the projec ⁇ tile 2 firmly to the element 8.
• the element 8 is accordingly provided with an opening 12 which is shaped to form a female coupling-part corresponding to the male coupling-part 11. The projectile is thus held against axial movement, by passing the coupling-part 11 and its associated shoulders 11a through the correspondingly shaped openings 12 in the element 8, and rotating the coupling-part through 45°.
• a locking device in the form of a flexible spring 13 on the rearward side of the element 8 is arranged to snap-in between two shoulders 11a on the coupling-part 11, to prevent it from turning.
• the thickness of the element 8 is equal to that of the groove 9, so that the element is seated securely in the groove. If, however, the container material located for ⁇ wardly of the container is structurally weak, as in the illustrated case of the Figure 1 embodiment in which the container presents the aforesaid narrowing part 3, the projectile may possibly break through this weak section 3 of the container in the event of a forward fall, as seen in the direction of the longitudinal axis of the projec ⁇ tile. In order to prevent this, the platelike element 8 is firmly secured rearwardly, seen in the longitudinal direction of the projectile, against a relatively heavily dimensioned container-part 14 behind the groove 9, with the aid of a strap 15 made of plastic or the like.
• the four support shoulders 17 form corner shoulders, thereby affording a very stable support surface.
• Each of the elements 8 and 16 has two apertures 19 and 20 respectively for anchoring the strap 15.
• the strap 15 can be tightened from the rearwardly located, open end of the container.
