foam dispenser

Abstract

Provided is a foam dispenser in which upward and downward displacement of an actuator causes a content liquid within a liquid cylinder (21) and air within an air cylinder (20) to be mixed and foamed, such that the foam so generated is dispensed from an outlet of a dispenser head (50). The dispenser head (50) has a structure with a minimized thickness to thereby increase the dispensing amount. The dispenser head (50) includes two members, i.e., a first member (50a) and a second member (50b), that have special configuration for allowing the two members (50a, 50b) to be easily removed from a die and formed in a small thickness.

Description

technical field [0001] The present invention relates to foam dispensers. Background technique [0002] As foam ejectors, there have been proposed various ejectors (for example, refer to Patent Document 1) in which the upper half is formed as a large-diameter cylinder and the lower half is formed as a small-diameter cylinder. (Cylinder) part hangs down in the container body, and from the cylinder part, the liquid in the small-diameter cylinder and the air in the large-diameter cylinder are pressed by the action part standing up under the state of applying force from above. The foamed part fitted in the operating part passes through and foams, and is discharged from the nozzle. [0003] In the manufacture of conventional foam dispensers, the main problem is simplification of the mold structure during molding. As a result, for example, the discharge head constituting the upper end of the operating part is formed as a single part and has a thick wall. [0004] prior art litera...

AI Technical Summary

Problems solved by technology

[0007] As a result, the size of the liquid passage is easily limited, and if a large discharge port or a discharge passage is required, the discharge head itself must be made very large, and there is a concern that the manufacturing cost will increase.
