As anadded feature' of obtaining shock and vibration absorption it may be preferable to calculate the outer dimensions of the inner container and the iner dimensions of the outer container and so predetermine the size of the corner vpads that upon closing. the flaps of the outer container the four pads will be placed under slight compression. In this manner when the assembly is`y subjected to shock or vibration any tendency for rebound of the inner container from one pad in any direction will be opposed by the oppositely disposed pad, or pads. This will destroy any tendency'to build up resonance or frequency of vibration of the inner container or the article contained therein.
Other specic forms, shapes and materials may be used in constructing the actual pads. For instance, while the form shown in Figure 3 is cored toinclude holes 26, certain flexible materials may be used which would dispense with the coring of the pads.
Figures 4, 5 and 6 show another form of pad; the general over-al1 contour of which conforms to that shown in Figure 3 but which is hollowed out for added flexibility and reduced weight.. In other words it still has the two side walls 1 and 8 intersecting in a corner 9 and also has a. ledge l0. t As seen in Figure 5, angular webs 29 and 30 extend between side walls 21 and 28 under ledge l0 and straight webs 3| and 32 extend between walls l' and Il and between walls 8 and l2 respectively. Such a construction tends toward` greater flexibility and the hollow under surface also provides an air cushion.
The foregoing construction and arrangement, in addition to resiliently suspending the inner container universally for shock and vibrationn absorption, also spaces the two containers to lessen the likelihood of moisture transfer from the exterior to the article contained. It also lessens the amount of shock absorbing material to be used. Moreover, the over-all weight and lsize of the cartons is materially lessened.
