Abstract
An electronic cigarette has a housing (2) formed by a plurality of thin rolled up layers with one or more grooves (6a, 6b, 6c, 6d, 6e, 6f, 6g) on an inside or outer surface of the housing (2). The housing (2) allows an opening to be formed to allow battery (3) gases to escape, avoiding over-pressurizing the housing (2), in the event of a battery (3) failure. The housing (2) may have a thickness of about 0.06 mm to about 2.5 mm. The layers may be bonded together by adhesives. The housing (2) may be formed around components of the electronic cigarette.
Claims15
An electronic cigarette with a soft housing, comprising:
- a cylindrical housing formed by two or more layers of a film of polymer, alloy, or pulping related composition bonded together via one or more adhesives;
- wherein:
- the housing has a wall thickness of about 0.06 mm to about 2.5 mm;
- the housing has one or more grooves on an inner surface of the housing, the one or more grooves configured for providing a pressure relief opening in the housing if the housing becomes over pressurized due to battery failure;
- and an atomizer, a liquid source and a sensor in the housing electrically linked to a battery.
An electronic cigarette having a soft housing, comprising:
- a cylindrical housing formed by two or more layers of paper or polymer film bonded together via one or more UV curable adhesives, wherein the layers of paper or polymer film are 50 to 100% transparent to UV light;
- the housing has a wall thickness of about 0.06 mm to about 2.5 mm;
- the housing has one or more grooves on an inner surface of the housing, the one or more grooves configured for providing a pressure relief opening in the housing it the housing becomes over pressurized due to battery failure;
- and
- an atomizer, a liquid source and a sensor in the housing electrically linked to a battery in a battery position in the housing, and with the one or more grooves overlapping the battery position.
