Valved gasket for dispenser

A dispensing unit for a fluid container comprising:

• a dispensing head, said dispensing head including two passageways and a dispensing orifice, said two passageways leading to said dispensing orifice;
• an upper venting member connected to the underside of said dispensing head, said upper venting member comprising at least one hole and at least one flap valve;
• and
• a lower venting member connected to the underside of said upper venting member, said lower venting member comprising at least one hole and at least one flap valve, said at least one hole on said upper venting member being aligned with said at least one flap valve on said lower venting member so as to allow air flow from one of said passageways to said fluid container, and said at least one flap valve on said upper venting member being aligned with said at least one hole on said lower venting member so as to allow air flow from said fluid container to said one of said passageways.

A valving arrangement for a dispenser comprising:

• an upper member with a hole, a flap valve and a centrally located flap valve;
• a lower member with a hole and a flap valve and a centrally located hole;
• said upper member overlaying said lower member;
• said hole on said upper member being aligned with said flap valve on said lower member and said hole on said lower member being aligned with said flap valve on said upper member;
• wherein said hole on said upper member cooperates with said flap valve on said lower member and said hole on said lower member cooperates with said flap valve on said upper member so as to respectively form two one-way valves, one for air flow in one direction and one for limited air flow only in an opposite direction, and wherein said centrally located flap valve is aligned with said centrally located hole so as to form a one-way valve for fluid flow.

A valving arrangement for a dispenser comprising:

• an upper member with a hole and a flap valve;
• a lower member with a hole and a flap valve, said lower member further comprising an annular projection for cooperating with a fluid conveying tube in the interior of said dispenser;
• said upper member overlaying said lower member;
• said hole on said upper member being aligned with said flap valve on said lower member and said hole on said lower member being aligned with said flap valve on said upper member;
• wherein said hole on said upper member cooperates with said flap valve on said lower member and said hole on said lower member cooperates with said flap valve on said upper member so as to respectively form two one-way valves, one for air flow in one direction and one for limited air flow only in an opposite direction.

A valving arrangement for a dispenser comprising:

• an upper member with a hole and a flap valve;
• a lower member with a hole and a flap valve;
• said upper member overlaying said lower member, said upper member including a hinged sealing member for cooperating with and sealing a dispensing orifice;
• said hole on said upper member being aligned with said flap valve on said lower member and said hole on said lower member being aligned with said flap valve on said upper member;
• wherein said hole on said upper member cooperates with said flap valve on said lower member and said hole on said lower member cooperates with said flap valve on said upper member so as to respectively form two one-way valves, one for air flow in one direction and one for limited air flow only in an opposite direction.

A valving arrangement for a dispenser comprising:

• an upper member with a hole and a flap valve;
• a lower member with a hole and a flap valve;
• said upper member overlaying said lower member;
• said hole on said upper member being aligned with said flap valve on said lower member and said hole on said lower member being aligned with said flap valve on said upper member;
• wherein said hole on said upper member cooperates with said flap valve on said lower member and said hole on said lower member cooperates with said flap valve on said upper member so as to respectively form two one-way valves, one for air flow in one direction and one for limited air flow only in an opposite direction, and wherein one of said members has an upstanding ridge which encircles the other of said members to retain said members together.

A valving arrangement for a dispenser comprising:

• an upper member with a hole and a flap valve;
• a lower member with a hole and a flap valve;
• said upper member overlaying said lower member;
• said hole on said upper member being aligned with said flap valve on said lower member and said hole on said lower member being aligned with said flap valve on said upper member;
• wherein said hole on said upper member cooperates with said flap valve on said lower member and said hole on said lower member cooperates with said flap valve on said upper member so as to respectively form two one-way valves, one for air flow in one direction and one for limited air flow only in an opposite direction, and wherein one of said members has a projection which cooperates with a recess in the other of said members to align said holes and said flap valves.

A dispenser comprising:

• a fluid container;
• and
• a dispensing unit attached to an open end of said fluid container;
• said dispensing unit including:
• a dispensing head with two passageways and a dispensing orifice;
• and
• a venting member between said dispensing head and said fluid container;
• said venting member including:
• a first resilient valve for allowing air to flow from a first of said two passageways to said container;
• a second resilient valve for allowing air to flow from an upper portion of said container to said first of said passageways, said second valve having sufficient resiliency so as not to open when said container is inverted when filled with fluid;
• and
• a conduit for allowing liquid to flow from a lower portion of said container to a second of said two passageways.

A dispenser comprising:

• a fluid container;
• and
• a dispensing unit attached to an open end of said fluid container;
• said dispensing unit including:
• a dispensing head with two passageways and a dispensing orifice;
• and
• a venting member between said dispensing head and said fluid container;
• said venting member comprising upper and lower gaskets and including:
• a first flap valve for allowing air to flow from a first of said two passageways to said container;
• a second flap valve for allowing air to flow from an upper portion of said container to said first of said passageways, said two passageways meeting in a chamber in fluid communication with said dispensing orifice;
• and
• a conduit for allowing liquid to flow from a lower portion of said container to a second of said two passageways.
