Benefits of technology

[0008] The present invention provides a coffee press structure having an improved container with transparent side wall portions and an improved plunger assembly, preferably in combination with an improved openable handle structure.

Problems solved by technology

One problem with prior art coffee presses has been that the user cannot adequately observe the status of the beverage being brewed in the container.
Although brewing status can be estimated by elapsed brewing time or by visually observing the color of a brew, with the characteristically opaque prior art coffee press containers, brew color cannot be adequately observed even if the associated plunger assembly is removed from the container.
To overcome this problem, a brewing apparatus having a container with transparent portions would be desirable, but such a container has sometimes been inadequate because either it tends to be fragile and easily broken during use, or it has transparent portions with edge regions that are not watertight so that undesirable leakage occurs from the container.
Another problem with prior art coffee presses is that, after a brewing operation, dispensing of the brewed and filtered beverage from the container is sometimes difficult to achieve in a simple, quick, effective and reliable manner.

Embodiment Construction

[0045] Referring to the Figures, there is seen an embodiment 50 of a coffee press of the present invention. The press 50 includes a housing or container assembly 51 and a plunger assembly 52. The container or housing assembly 51 comprises a cylindrical vessel 53 having generally cylindrical side walls 54, a closed bottom 55, and an open top mouth 56 whose exterior, adjacent lip regions 57 are threaded. The vessel 53 is preferably comprised of a unitarily molded, transparent molded plastic. Various plastics are suitable and preferably are impact resistant and also heat resistant both for purposes of holding heated aqueous liquids, like coffee or tea, and for purposes of washing the press 50 in an automatic dishwasher or the like. Examples of suitable plastics include polycarbonates, various polyacrylics, certain styrenic polymers, and the like, as those skilled in the art will readily appreciate.

[0046] The base or lower portion of the vessel 53 is associated with an overfitting, uni...

Abstract

An improved coffee press structure is provided wherein the container has transparent side wall portions that are associated with top and bottom caps and an intermediate cage structure. Upper and lower band portions of the cage structure are associated with a handle upper end portion and with a link member, respectively. The link member is pivotable relative to either the handle lower end portion or the lower band portion and is spring biased so that when in a normally closed position, the link member closes the gap between the handle lower end portion and the lower band portion. The press structure also provides two different embodiments of a plunger assembly for association with the container mouth. The plunger assembly embodiments both include a handle, a piston and a rod; and the plunger assembly can remain in place after brewing and during brew dispensing from the container. One of the plunger assembly embodiments includes a spouted lid that is valve equipped, the valve being operated by rotational movement of the handle relative to the lid with the rod being fully extended through the lid.

Description

RELATED APPLICATION [0001] This application is a continuation-in-part of pending U.S. Ser. No. 10 / 651,791, filed Aug. 29, 2003.FIELD OF THE INVENTION [0002] The present invention relates to presses for coffee, tea or the like, and, in particular, to presses having an open top container with preferably transparent side wall portions and with associated bottom and top protective and enforcement portions, and a reciprocating plunger assembly associated with the container. BACKGROUND OF THE INVENTION [0003] Portable, hand-operable brewing / filtering devices or coffee presses have been available for many years. Such an apparatus typically includes a container having an openable top and side walls having a uniform internal cross-section. The top is provided with a lid that receives a slidable rod which is axially reciprocable relative to the container. The rod has a handle at its upper end and a piston at its lower end. The rod and the piston with the lid comprise a plunger assembly. When ...
