No. Force isn't something you can enclose in a box, an envelope, or a bottle.
A stick of dynamite contains some amount of a chemical compound which, when triggered by enough heat or shock, undergoes a chemical reaction that proceeds very rapidly, and generates a large quantity of gases before the gases can dissipate. This creates very high pressure around the reaction, and it's this pressure in a small volume that exerts great force for a very short time. The whole process is often described as an "explosion".
