Plunger and lid apparatus for a beverage press and a beverage press having same
A plunger device for use with a beverage press having a screen for filtering fines from an infused beverage. A flexible seal is provided that is compressible to function properly in different sized containers. The seal may be made of a material such as rubber or rubberized plastics or the like and may have a width that is greater than its thickness. Various seal embodiments including ascending, descending and non-circular embodiments are disclosed. Brew control and multiple access openings are also disclosed.
1. A plunger device for a beverage press, comprising:
a lid;
a shaft movably provided through said lid;
a substantially planarly disposed screen provided proximate one end of said shaft for filtering fines from an infused beverage;
a flexible seal structure disposed outwardly of said screen, a perimeter of said seal structure defining a first area in a substantially horizontal plane when at rest and being compressible to define a second area in a substantially horizontal plane when compressed in a beverage press vessel that is smaller by 20% or more than said first area, the seal being configured so that the perimeter when compressed into the second area maintains a functional seal; and
wherein the seal member ascends from and extends in a substantially linear or outwardly tapering manner, in vertical cross-section, from the planarly disposed screen
wherein said seal structure is comprised of a seal member made of a flexible material that is inherently self biased towards a position defining said first area;
wherein said flexible seal member extends from a fixed support structure therefor by a distance that is at least substantially three times the thickness of the flexible seal member at the fixed support structure; and
further comprising a releasable brew control device having a substantially continuous closed surface that is actionable by a user to substantially cover said screen;
wherein said brew control is actionable through said lid and descends the shaft into a position that covers the screen, thereby blocking fines from the infused beverage.
2. The device of claim 1 , wherein said seal member is comprised of natural or synthetic rubber.
3. The device of claim 1 , wherein said seal structure as viewed from above is substantially non-circular.
4. A plunger device for a beverage press, comprising;
a lid;
a shaft movably provided through said lid;
a screen provided proximate one end of said shaft for filtering fines from an infused beverage;
a frame supporting said screen;
a flexible seal structure disposed outwardly of said frame; and
a brew control device substantially planar in shape and having a substantially continuous closed surface that is actionable by a user to substantially cover said screen, and thereby reduce contact between fines excluded from an infused beverage and the remaining beverage;
wherein said brew control is actionable through said lid; and
wherein said seal structure includes a seal member that is formed of a natural or synthetic rubber and is disposed outwardly of said screen, said seal member having a width that is at least three times greater than its thickness.
5. The device of claim 4 , wherein said seal structure is flared in vertical cross-section.
