Liquid dispenser with valve
View Patent ↗A fluid dispenser has a main body, a valve member, and a dome member. The dome member is attached to the valve member such that the valve member is slidable within the main body. Pressing on the dome member opens the valve so that fluid can flow out of a dispensing port in the main body. The main body has an outer flow surface and an inner flow surface. The valve has a face. In conjunction, the outer flow surface, inner flow surface, and face define a fluid passageway for fluid to flow exteriorly to the inner flow surface, interiorly to the outer flow surface, and exit the fluid dispenser via the dispensing port.
1. A fluid dispenser having a flow configuration and a sealed configuration, the fluid dispenser comprising:
a main body, the main body having an outer flow surface and an inner flow surface, the outer flow surface having an opening therethrough defining a dispensing port;
a dome member; and
a valve member, the valve member having a face and being coupled to the dome member;
wherein, when the fluid dispenser is in the flow configuration, the outer flow surface, inner flow surface, and face define a fluid passageway for fluid to flow exteriorly to the inner flow surface, interiorly to the outer flow surface, and exit the fluid dispenser via the dispensing port, and
further wherein the main body has a seal, the seal defining a sealing plane extending therethrough, the face angled with respect to the sealing plane at an angle between 20 and 45 degrees.
2. The fluid dispenser of claim 1 , wherein the valve member further comprises a stem, the stem being coupled to the dome member.
3. The fluid dispenser of claim 2 , wherein the main body comprises a guide through which the stem extends.
4. The fluid dispenser of claim 3 , wherein the guide comprises the inner flow surface.
5. The fluid dispenser of claim 1 , wherein at least a portion of the outer flow surface is in opposing relationship with the inner flow surface.
6. The fluid dispenser of claim 1 , wherein the valve member has an outer tubular portion, the outer tubular portion contacting the seal when the fluid dispenser is in the sealed configuration.
7. The fluid dispenser of claim 6 , wherein the valve member has an intermediate tubular portion and the seal is disposed between the outer tubular portion and the intermediate tubular portion when the fluid dispenser is in the sealed configuration.
8. The fluid dispenser of claim 7 , wherein the valve member comprises a wedge extending from the intermediate tubular portion, the wedge configured to contact a side of the seal opposite the outer tubular portion.
9. The fluid dispenser of claim 1 , wherein the dome member is formed of an elastomeric material.
10. The fluid dispenser of claim 1 , wherein the main body comprises a dividing wall, the face opposing the dividing wall.
11. The fluid dispenser of claim 1 , wherein the main body has at least one stand-off member.
12. The fluid dispenser of claim 11 , wherein the at least one stand-off member defines a recess.
13. The fluid dispenser of claim 12 , wherein at least a portion of the dome member is seated against the recess.
14. The fluid dispenser of claim 1 further comprising a cap.
15. The fluid dispenser of claim 14 , wherein the cap has at least one tear strip.
16. A fluid dispenser comprising:
a main body having a sidewall with a first opening therein, and a seal;
a valve member slidable within the main body, the valve member having an open position and a closed position, the valve member having a channel therein, the channel having a first sidewall and a second sidewall opposite the first sidewall, when the valve member is in the closed position, the seal extends into the channel and contacts the first and second sidewalls,
the main body and valve member defining a second opening and flow passage therebetween, when the valve member is in the open position, the flow passage extending from the first opening to the second opening and when the valve member is in the closed position, the flow passage being sealed by contact between the seal and at least the first sidewall, and
wherein the seal defines a sealing plane extending therethrough, the face angled with respect to the sealing plane at an angle between 20 and 45 degrees.
17. The fluid dispenser of claim 16 , wherein the second sidewall comprises a wedge extending into the channel.
18. The fluid dispenser of claim 16 , wherein the first sidewall comprises a lobe.
19. A fluid dispenser comprising:
a main body having a sidewall with an opening therein through which fluid can be dispensed;
an elastomeric dome member; and
a movable valve member, the valve member movable between a sealed position and an open position, the valve member having a stem which is coupled to the elastomeric dome member, the stem having a longitudinal axis,
in the open position the main body and valve member defining a flow passage which ends at the opening,
wherein the flow passage includes a section which extends 360 degrees about the stem and is bounded by the main body and the valve member, the flow passage being a slanted passage which slants relative to the longitudinal axis of the stem, and
further wherein the main body has a seal, the seal defining a sealing plane extending therethrough, the face angled with respect to the sealing plane at an angle between 20 and 45 degrees.
