Title:
TRIGGER TYPE LIQUID SPRAY DEVICE
Document Type and Number:
Japanese Patent JP2023050601
Kind Code:
A
Abstract:
To provide a trigger type liquid spray device capable of improving component durability by suppressing concentration of a large load to an energization member as well as an engaging part of the energization member.SOLUTION: A trigger type liquid spray device comprises: a spray device body 10 attached to a container body A; and a nozzle member 11 attached to a front end part of the spray device body 10 and formed with a spray hole 11a. The spray device body 10 comprises: a vertical supply cylindrical part 20 extending in an upward-downward direction; a pump part 22 for feeding liquid toward the spray hole 11a through the vertical supply cylindrical part 20; a trigger part 18 movably provided in a front-and-rear direction in front of the vertical supply cylindrical part 20 and for operating the pump part 22; and an energization member for energizing the trigger part 18 frontward. The pump part 22 comprises a volume-variable part for increasing or decreasing an internal volume with forward and backward movement of the trigger part 18. The volume-variable part is constituted so as to be elastically deformable and energizes the trigger part 18 frontward when the trigger part 18 is moved backward.SELECTED DRAWING: Figure 1
