Abstract

Disclosed in the present invention is a pump type dispenser which includes a pump held by a mouth portion of a container and configured to suction and pressure-feed a content liquid in the container, and a nozzle head having an internal passage through which the pressure-fed content liquid passes and driving the pump by being repeatedly pushed down and restored. The internal passage includes a vertical passage, a lateral passage, and a protrusion protruding toward an inner side in a joining portion between the vertical passage and the lateral passage, and a dispensing member disposed in the lateral passage includes a recessed portion which engages with the protrusion to prevent separation from the lateral passage.

First claim

The invention claimed is:

1. A pump type dispenser comprising:
a pump held by a mouth portion of a container and configured to suction and pressure-feed a content liquid in the container; and
a nozzle head having an internal passage through which the pressure-fed content liquid passes and driving the pump by being repeatedly pushed down and restored,
wherein
the internal passage includes a vertical passage communicating with the pump and a lateral passage connected to the vertical passage and provided with an opening that opens toward the outside, and the nozzle head includes a top wall serving as a pressing portion to push down the nozzle head and a protrusion protruding from the top wall toward the vertical passage in a joining portion in which the vertical passage and the lateral passage are connected,
a dispensing member extending from the opening of the lateral passage toward the joining portion and configured to dispense the content liquid introduced from an inlet of the dispensing member close to the joining portion from an outlet of the dispensing member close to the opening is disposed in the lateral passage, and
the dispensing member includes a recessed portion which engages with the protrusion to prevent separation from the lateral passage.

2. The pump type dispenser according to claim 1 , wherein the dispensing member is made of a resin having flexibility and is bent with respect to an initial state after molding when disposed in the lateral passage.

3. The pump type dispenser according to claim 1 , wherein the vertical passage includes a vertical rib protruding toward an inner side and extending along the vertical passage and the dispensing member includes a notch portion which engages with the vertical rib.

4. The pump type dispenser according to claim 2 , wherein the vertical passage includes a vertical rib protruding toward an inner side and extending along the vertical passage and the dispensing member includes a notch portion which engages with the vertical rib.

5. The pump type dispenser according to claim 3 , wherein a foam member which foams the content liquid is provided on a downstream side of the pump and the vertical rib comes into contact with an upper end of the foam member.

6. The pump type dispenser according to claim 4 , wherein a foam member which foams the content liquid is provided on a downstream side of the pump and the vertical rib comes into contact with an upper end of the foam member.
