I used take-away containers with a cling film cover. Remove container lid, slit cling film, place over a feed hole and cover with a 100mm slab of EPS cut to accommodate the dish.
It never dripped, one can easily see when it is consumed and add another pack by gently sliding across.
Worked a treat and OK for a few hives late in the winter. I now have 25kg of fondant that has not been used for several years. The last 12 1/2 kg was used up on nucs as 14 x 12 colonies, well stocked with stores in the autumn, are more likely to require stores frames removing in spring.
Well insulated hives allow the cluster to move around - more than with uninsulated ones during a really cold snap, while brooding early in the season.
