This type of feeder is
designed on the Bro. Adam principle and measures
185 mm square x 54.5 mm tall, it is useful for feeding nucs.
Square & Rectangular Plastic Feeders
There is a rectangular version which is 306 mm x 206 mm x 56 mm tall
that is mentioned on the page that deals with
feeding two 5 frame nucs
side by side.
I am not aware of the maker's name but the logo and lettering in
the centre of the lid are likely to be the manufacturer's trademark.
The cross section shows the inverted round plastic cup that shrouds the
feeding cone in the centre. This cup has a notch that can be
positioned to allow bees into the main tray when it is nearly empty.
This feature can be disabled by positioning the cup so that the notch
is blocked by one of the four pegs that the cup itself is located on.
The lid is needed to stop excessive evaporation and resulting
crystalisation of the feed.
I use about 2 dozen of these feeders... The troughs are quite strong
but the transparent lids tend to crack easily and thus have a shorter
lifespan, several of mine now have thin plywood lids.
Scale is 2 pixel = 1 mm.
