Insect-Repellant Utensil and Process For Production Thereof

An insect repellent device adapted to repel insects by being held and waved by hand, comprising:

• a frame;
• and
• at least one face-forming member arranged on at least one surface of the frame,
• wherein the face-forming member has at least one exposed surface exposed to atmospheric air,
• the at least one exposed surface having a coating layer,
• the coating layer holding an insect controlling agent containing an active ingredient being volatilizable at normal temperature and being effective in insect-repellent,
• the active ingredient being a pyrethroid compound having a vapor pressure at 25 degrees centigrade by Donovan method within a range of 1.33×10−4 to 6.67×10−1 Pa, and
• the device holding the agent within a range of 1 to 1000 mg in total.

An insect repellent device adapted to repel insects by being held and waved by hand, comprising:

• a frame having a frame body and a handle;
• and
• at least one face-forming member made of paper, printed in ink, and arranged on at least one surface of the frame,
• wherein the face-forming member has at least one exposed surface exposed to atmospheric air,
• the at least one exposed surface having a varnish layer,
• the varnish layer holding an insect controlling agent containing an active ingredient being volatilizable at normal temperature and being effective in insect-repellent,
• the active ingredient being a pyrethroid compound having a vapor pressure at 25 degrees centigrade by Donovan method within a range of 1.33×10−4 to 6.67×10−1 Pa, the device holding the agent within a range of 1 to 1000 mg in total, and
• at least the face-forming member being contained and hermetically sealed in a bag made of a material impermeable to the active ingredient contained in the agent.

A method for manufacturing an insect repellent device of a foldable or unfoldable fan shape constituted by a frame having a frame body and a handle, comprising the steps of:

• adhering a face-forming member to the frame;
• and
• applying a varnish to a surface of the face-forming member before or after the step of adhering the face-forming member to the frame,
• the varnish containing an insect controlling agent containing an active ingredient being volatilizable at normal temperature.
