Abstract:
A foamer dispenser including a mesh filter that is disposed in a mixture flow path of a jet ring to allow a mixture to pass is provided. A connecting flow path area between a liquid flow path and the mixture flow path and a connecting flow path area between an ambient air flow path and the mixture flow path have the relation 2.8≤S 1 /S 2 ≤3.8, and/or, a smallest flow path area of the mixture flow path is located on an immediately upstream side of the mesh filter, and the smallest flow path area and a flow path area of the mesh filter have the relation 4≤S 4 /S 3 ≤10.3.

Claim (Index 1):
A foamer dispenser, comprising:\n a pump cover that is fitted to a container body; a pump cylinder that includes a large-diameter portion fixed to the pump cover and a small-diameter portion; a small-diameter piston that is received in the small-diameter portion of the pump cylinder and that is configured to suck and pump a liquid in the container body; a large-diameter piston that is received in the large-diameter portion of the pump cylinder and that is configured to suck and pump ambient air; a head that causes pumping movement of the small-diameter piston and the large-diameter piston and that ejects a mixture of the liquid and the ambient air by a user pushing and releasing the head repeatedly; a liquid flow path of the liquid pumped from the small-diameter piston; an ambient air flow path of the ambient air pumped from the large-diameter piston; a mixture flow path of the mixture of the liquid pumped from the liquid flow path and the ambient air pumped from the ambient air flow path; and a mesh filter that is disposed in the mixture flow path to allow the mixture to pass, wherein a smallest flow path area S 3  of the mixture flow path is located on an immediately upstream side of the mesh filter, and the smallest flow path area S 3  and a flow path area S4 of the mesh filter have the following relation:\n 4 \u2264S 4 /S 3 \u226410.3, \n wherein a check valve is located in the liquid flow path on a downstream side of the small-diameter piston, and a slip-off preventing member that restricts movement of a valving element of the check valve provides an opening configured to communicate the liquid flow path and the mixture flow path with each other.
