Puncture gas cylinders

 

— a cylinder with a solid shell that does not have valves; when connected to the burner, this sheath is pierced with a special tool on the mount. Such containers are extremely simple and inexpensive, but they have a serious drawback — the cylinder cannot be removed from the burner while gas remains in it. Therefore, the use of puncture tanks is limited to cottages, campsites, etc. — in such an environment, this drawback is not critical.
