Abstract
A dispenser capable of discharging a liquid material from a discharging opening includes a pump chamber capable of sucking the liquid material; a first communication port as an outlet provided in the pump chamber; and a first passage as a pathway provided to make the first communication port and the discharging opening communicable with each other and allowing the flow of the liquid material. The first communication port is positioned on the opposite side to the discharging opening across a central axis of the pump chamber.
Claims22
1:
- A dispenser capable of discharging a liquid material from a discharging opening, comprising:
- a pump chamber capable of sucking the liquid material;
- an outlet provided in the pump chamber;
- and
- a pathway provided to make the outlet and the discharging opening communicable with each other and allowing flow of the liquid material, wherein
- the outlet is positioned on an opposite side to the discharging opening across a central axis of the pump chamber.
3 more elements
2:
- The dispenser according to claim 1, wherein the outlet is positioned on a diametrically opposite side to the discharging opening across the central axis of the pump chamber.
3:
- The dispenser according to claim 1, comprising:
- two or more of the outlets.
4:
- The dispenser according to claim 1, comprising:
- two or more of the pathways.
5:
- The dispenser according to claim 1, further comprising:
- a handle section provided on the opposite side to the discharging opening across the central axis of the pump chamber.
6:
- The dispenser according to claim 1, further comprising:
- a dispenser body having a depression;
- and
- an elastically deformable lid section covering the depression and forming the pump chamber together with the depression.
1 more element
7:
- The dispenser according to claim 6, wherein the dispenser body further has a suction port communicating with the depression, wherein the liquid material is sucked into the pump chamber from the suction port.
8:
- The dispenser according to claim 6, wherein the lid section has a dome shape bulging out to a side opposite to a side of the depression.
(canceled)
10:
- The dispenser according to claim 6, wherein a bottom surface of the depression has a circular shape or an oval shape in plan view.
11:
- The dispenser according to claim 6, wherein the outlet is provided at an outer edge of the pump chamber in a radial direction of the depression.
12:
- The dispenser according to claim 6, wherein the pathway is provided outside the pump chamber in the radial direction of the depression.
13:
- The dispenser according to claim 6, wherein an annular groove surrounding the depression is positioned on a side to which the lid section is attached in the dispenser body and the pathway is formed by the annular groove.
14:
- The dispenser according to claim 13, further comprising:
- an elastic member including the lid section and attached to the dispenser body, wherein the pathway is formed by the annular groove and the elastic member.
15:
- The dispenser according to claim 13, wherein an inner wall of the annular groove also serves as a wall of the pump chamber.
16:
- The dispenser according to claim 13, further comprising:
- a projection engageable with the annular groove on an outer periphery of the lid section.
17:
- The dispenser according to claim 16, wherein the projection engageable with the annular groove has an annular shape.
18:
- The dispenser according to claim 13, further comprising:
- an annular projection projecting from an inner surface of the lid section and slidable against the inner wall of the annular groove in response to elastic deformation of the lid section.
19:
- The dispenser according to claim 6, wherein the lid section is provided to be elastically deformed such that a flow path cross-sectional area of the pathway is larger when a volume of the pump chamber is large than when the volume of the pump chamber is small.
20:
- The dispenser according to claim 6, further comprising:
- a biasing unit capable of biasing the lid section from a side of the pump chamber and a locking portion which has a tubular shape projecting from the inner surface of the lid section and with which the biasing unit is locked, wherein
- the locking portion is provided with a slit, and
- the slit is positioned on an opposite side to the discharging opening across an axis of the locking portion.
1 more element
21:
- The dispenser according to claim 20, wherein the slit is positioned on a diametrically opposite side to the discharging opening across the axis of the locking portion.
22:
