Description
The body of this grenade consists of a Japanese beer bottle into the top of which is fitted an "all-way" action fuze. There is a rubber washer under the fuze to render it liquid tight, and the fuze fits into the neck of the bottle in the manner of a crown stopper.
The fuze consists of a firing pin contained in a housing and separated from the detonator contained in a carrier by a safety pin and a creep spring. The firing pin housing has a hemispherical weight on the top of it and bears against the underside of the nose cap which is of a similar shape. The bottom of the detonator carrier is also rounded and bears against a cam surface so that it too is free to move. The safety pin runs through the firing pin housing and rests against the top of the detonator carrier so that neither part is free to move. Beneath the detonator there is an incendiary mixture consisting of barium nitrate and magnesium.
Functioning
The safety pin is pulled out and the grenade is thrown. On impact the "all-way" fuze will function and set off the detonator thus igniting the incendiary booster and inflammable filler.
