Vaporizing device with sliding cover to eliminate loss of vapors

A system for vaporizing and dispensing material for inhalation, comprising:

• an electronic handheld device comprising:
• a ceramic heater within a handheld casing;
• a ceramic bowl connected to the heater and heated by the heater, the bowl located at a first end of the casing and containing combustible material;
• two parallel rails protruding from the first end below the bowl;
• a sliding cover attached to the rails that:
• prior to the combustible material commencing conversion into vapor based on the applied heat, remains situated at a far end of the rails and away from the bowl, the situation comprising an open position,
• upon the combustible material commencing vaporization, receives sliding movement into a closed position over the bowl, and
• prevents, while remaining in the closed position, vapors from escaping.

A system for heating, vaporizing, and dispensing combustible substances, comprising:

• a handheld device comprising:
• a rectangular metal case, the case containing:
• a printed circuit board (PCB),
• a battery,
• a heating element with a bowl for containing combustible substances, the bowl at a first end of the case,
• a mouthpiece at a second end of the case,
• twin rails protruding from a lower area of the first end;
• and
• a cover positioned atop the rails and slidable on the rails over the bowl and alternatively slidable away from the bowl that:
• receives movement away from the bowl and into an open position, the movement exposing the bowl to user access,
• upon the bowl receiving placement of a combustible substance and upon the substance receiving heat from the element and producing vapor, receives movement toward and over the element, and
• traps vapor inside the case.
