Claims
- 1. In a lighter having a lighter body forming a reservoir, a well adapted to receive a filling valve assembly for the controlled outflow of fuel from said reservoir, the improvement which comprises in combination with said valve assembly of:
- an annular wall portion formed on said well in said body; and
- an axially shiftable obturator having axially spaced first, second and third sections, said first section being formed with a passage enabling filling of said reservoir through said well with a liquid fuel upon the positioning of said obturator with said first section in said wall portion in a first position of said obturator and prior to fitting of said valve assembly in said well, said second section of said obturator having a cross section corresponding to that of said annular portion for blocking fuel flow from said well upon positioning of said second section in said annular portion in a second position of said obturator whereby said valve assembly can be inserted in said well without escape of fuel, said third section being of a cross section less than that of said annular portion whereby disposition of said obturator with said third section in said annular portion allows permanent free passage of fuel to said valve assembly after it has been inserted in said well.
- 2. The improvement defined in claim 1 wherein said obturator is unitary with said body and is connected with said well via frangible means.
- 3. The improvement defined in claim 2 wherein said obturator is connected with said well at an edge of said second section and at an innermost lip of said well.
- 4. The improvement defined in claim 1 wherein said obturator is formed with a free end beyond said third section which is lodged in said valve assembly and define fuel-flow passages therewith.
- 5. The improvement defined in claim 2 wherein said obturator is formed with a free end beyond said third section which is lodged in said valve assembly and define fuel-flow passages therewith.
- 6. The improvement defined in claim 3 wherein said obturator is formed with a free end beyond said third section which is lodged in said valve assembly and define fuel-flow passages therewith.
