Flashlight assembly

A flashlight comprising:

• a lighting means;
• an elongated hollow housing joined with said lighting means for receiving a set of batteries which are adapted to be aligned within said elongated hollow housing, making contact singly and electrically connecting in series, constituting an electric circuit with said lighting means, said elongated hollow housing having a hole formed at a position where, when a non-conductive sheet is inserted therethrough, the electrical contact of said batteries can be broken;
• said elongated hollow housing further comprising:
• a first hollow housing having a first end and a second end, said first end being joined with said lighting means and said second end having a first hole formed therein;
• and
• a second hollow housing having a third end and a fourth end, said third end having a second hole formed therein and being adapted to rotatably join with said second end so that said second hollow housing can be joined with said first hollow housing, forming the elongated hollow housing, and rotated to a certain angle where said second hole is aligned with said first hole, forming the through hole, and said fourth end being covered by a removable cap upon the removal of which, said set of batteries can be put into said elongated hollow housing and aligned singly so as to make electrical contact with each other;
• wherein said first hollow housing comprises a hollow joint member, axially extending from said second end and having said first hole formed therein, adapted to insert into and join with said third end of said second hollow housing;
• and
• wherein said joint member further comprises a packing member having a third hole formed therein, said packing member being tightly fixed around said joint member, aligning said third hole with said first hole, and protecting the inside of said elongated hollow housing from the infiltration of moisture into the joint between said first and second hollow housings.
