Dispenser
A dispenser, which has a pump chamber formed by a body including a depression, and a lid body covering an opening of the body, where a liquid in the pump chamber is discharged from a nozzle portion by performing a discharge operation that presses the lid body to an inside of the pump chamber to deform the lid body, and a liquid is caused to flow into the pump chamber by releasing the discharge operation. The dispenser includes a pressing support portion disposed to face away from a top surface of the lid body, and a discharge operation is performed by pinching a top portion of the lid body and the pressing support portion with fingers from lateral sides of the body.
1. A dispenser, comprising:
a pump chamber is formed by a body including a depression and a lid body covering an opening of the body, wherein a first liquid in the pump chamber is discharged from a nozzle portion by performance of a discharge operation that presses the lid body into an inside of the pump chamber to deform the lid body and a second liquid is caused to flow into the pump chamber by release of the discharge operation;
a suction passage having an open end that opens toward the pump chamber; and
a pressing support portion that is disposed to face away from a top surface of the lid body, wherein
the discharge operation is performed by pinching the top surface of the lid body and the pressing support portion from lateral sides of the body,
wherein the suction passage extends along a direction orthogonal to a discharge operation direction of the lid body,
the lid body is formed of a material that is elastically deformable,
when the lid body is pressed in the discharge operation, the lid body bends into the pump chamber,
wherein a part of the lid body is deformable toward the inside of the pump chamber such that, at an inside of the depression, a part of the lid body overlaps with a part of the open end of the suction passage, after the discharge operation is performed, when the open end of the suction passage is viewed from a front direction.
2. The dispenser according to claim 1 , wherein a distance from the pressing support portion to the top surface of the lid body is 5 mm or more and less than 30 mm.
3. The dispenser according to claim 1 , wherein when an imaginary plane that passes through a center line of the nozzle portion and that is perpendicular to a discharge operation direction that is a pressing direction of the lid body when performing the discharge operation is set as a reference, a distance from the imaginary plane to the top surface of the lid body is set as L 1 , and a distance from the imaginary plane to the pressing support portion is set as L 2 , L 1 >L 2 is established.
4. The dispenser according to claim 1 , wherein
the lid body is provided to bulge with respect to the body, and
the lid body includes a flat top surface.
5. The dispenser according to claim 1 , wherein the pressing support portion is a flat surface.
6. The dispenser according to claim 1 , wherein the top surface of the lid body and an end surface that is the pressing support portion are arranged to face away from each other.
7. The dispenser according to claim 1 , further comprising a coil spring in the pump chamber, the coil spring urging the lid body to an outside.
8. The dispenser according to claim 7 , wherein
one end side of the coil spring is placed on a bottom surface of the depression, and
another end side of the coil spring abuts on an inner surface of the lid body.
9. The dispenser according to claim 8 , wherein the bottom surface on which the coil spring abuts and the pressing support portion face opposite directions.
10. The dispenser according to claim 1 , wherein
the body includes a suction passage as a flow passage for the second liquid that flows into the pump chamber and a discharging passage as a flow passage for the first liquid that is discharged from the nozzle portion, and
the suction passage and discharging passage communicate with the pump chamber.
11. The dispenser according to claim 10 , wherein respective centers of the suction passage and the discharging passage are arranged in series and located on a same straight line.
12. The dispenser according to claim 10 , wherein the suction passage and the discharging passage are disposed opposite to one another with respect to the pump chamber.
13. The dispenser according to claim 1 , wherein
a bottom surface of the body faces an inner surface of the lid body that faces the pump chamber, and
the pressing support portion is located at an end surface of the body which is an opposite side of the bottom surface of the body.
14. The dispenser according to claim 1 , wherein, when the lid body is pressed in the discharge operation, the top surface of the lid body is pressed into the inside of the pump chamber.
15. The dispenser according to claim 1 , wherein, when the lid body is pressed in the discharge operation, the top surface of the lid body exists between two surfaces that form the pump chamber and oppose one another.
