Abstract
The present system relates a French Press that comprises a carafe with a removable bottom member. The bottom member is threaded onto the man body of the carafe and forms a watertight seal during use of the carafe. During the preparation of the coffee using the French Press, normal operation is possible. The spend solids collect naturally in the bottom member during use, and are in fact urged there by depression of the plunger during operation. After use, the bottom member can be easily removed from the main body of the carafe and the spent solids can be easily cleaned from the bottom member, along with any stray spent solids that might have remained in the main body of the carafe.
Description
- There are a number of methods and apparatuses for the preparation of coffee and tea drinks. One method is the use of a so called “French Press.” The French Press, also referred to as a press pot, plunger, coffee press, cafetiere, and the like, comprises a carafe for holding liquid, with a lid and a plunger. Coffee grounds/tea is placed into the carafe, which is then filled with hot water. The lid contains the plunger, which includes a wire mesh, circular spring, or other filter like mechanism. With the lid on the plunger, it is pressed toward the bottom of the carafe to separate the coffee grounds/tea from the infused liquid which is intended for consumption. While pouring the infused liquid, the plunger stays in place to prevent the grounds/tea from also leaving the carafe.
- After preparation and the infused liquid is poured out, the lid and plunger are removed, and the carafe is then cleaned of the used coffee grounds/tea in anticipation of the next use. However, the cleaning of the spent solids is difficult. The spent solids are either scooped out by hand or with a device such as a spoon, or forcibly ejected by rapping the carafe on a hard surface while upside down, and the carafe is then wiped with sponge or cloth or placed into the dishwasher to remove all of the spent solids and oil residue of the liquid. This is an extremely messy process where the spent solids are often stuck in the press and may involve quite a bit of effort to fully clean the carafe for the next use.
- The present system provides a French Press that comprises a carafe with a removable bottom member. The bottom member is removably attached, for example, with a threaded or snap connection, to the main body of the carafe and forms a liquid tight seal during use of the carafe. During the preparation of the coffee using the French Press, normal operation is possible. The coffee grounds/tea leaves are urged into the bottom member by depression of the plunger. After the infused liquid has been removed, the bottom member can be easily removed from the main body of the carafe and the spent solids can be easily cleaned from the bottom member. Not only is the bottom member easier to clean because of its shallow depth, but the carafe itself is easier to clean because it can be accessed from either the top or bottom of the carafe, instead of rinsed and tipped as with prior art systems.
- In addition, the present disclosure relates to a brewing device. The brewing device includes a hollow main body having an open top end, an open bottom end, and an outer wall extending from the top end to the bottom end, a plunger assembly disposed within the main body and moveably disposed between the open top end and the open bottom end of the main body, an optional handle assembly extending from the outer wall of the main body, and a bottom member that is removably attached to the main body at the open bottom end. The plunger assembly includes a hollow shaft having an open top end, an annular interior surface that extends through the top end of the shaft, a plunger plate attached to a bottom end of the shaft, and a plunger head attached to the top end of the shaft. The plunger head and the annular interior surface of the hollow shaft are sized and shaped to receive a thermometer having a head portion and stem portion extending from the head portion such that when the stem portion of the thermometer is inserted into the shaft, the head portion of the thermometer is positioned against the plunger head of the plunger assembly. In other embodiments, the thermometer could be removably attached to another portion of the carafe, such as in the handle, on the lid, on the bottom member, or on the outer surface of the carafe. The optional handle assembly includes an elongate body having an upper end, a lower end opposite the upper end, and an interior compartment located between the upper end and the lower end, where the interior compartment is sized and shaped to house a removable timekeeper. The bottom member includes an annular interior wall and a bladder that extends outwardly from a center axis to the annular interior wall, the bladder being movable to aid in the removal of the spent solids from the bottom member.

The main body may include a pourspout 106 to aid in pouring the liquid from themain body 101. In one embodiment themain body 101 is composed of glass. However, the main body may be composed of any suitable material for providing, with the bottom member, a receiver for fluids such as coffee. - The
device 100 includes abottom member 102 that may be removably attached to themain body 101. In one embodiment, thebottom member 102 is removably attached by matching threads on the interior of the bottom member 102 (not shown inFIG. 1B ) andthreads 108 on the exterior of the bottom portion of main body 101 (seeFIG. 1B ). Although shown as removably coupled via threads for a screw on operation, the bottom member may also be removably coupled via other means, such as a compression fit, keyed or registered clips or lips for locking the bottom member in place, or any other suitable coupling means. - During operation, the bottom member should provide a substantially fluid-tight seal so that coffee is not compressed through the boundary between the bottom member and the main body. The bottom member may be composed of plastic, metal, or glass as desired.
- The
device 100 includes alid 104 through which aplunger assembly 105 is inserted. Typically, the plunger and lid assembly are coupled together and work as a unit. During operation, the lid is pressed down, thereby pushing theplunger plate 110 down toward the bottom of themain body 101. Thelid 104 engages the top opening ofmain body 101 to both retain the liquid in thedevice 100 during operation to retain heat after brewing, and to support theplunger assembly 105 in place to keep grounds below the filter assembly. Thelid 104 may be metal or plastic as desired. - The
plunger assembly 105 comprises ashaft 109 coupled to aplunger plate 110. Theplunger plate 110 typically has openings formed in the face thereof and covered by a wire mesh or screen. The screen acts as a filter to allow fluid to pass there-through while preventing the grounds from pass through. Often a spring, such asspring 111 is disposed circumferentially around the outer edge of theplunger plate 110 to urge theplunger plate 110 to a correct position and provide appropriate force between the plunger plate and sidewall of the main body to prevent grounds from entering the liquid chamber via the gap between the plunger body and side wall. Themain body 101 is positioned such that theshaft 109 is coaxial with the cylinder of themain body 101. - The plunger assembly is typically metal but may be a combination of metal or plastic or any materials that provide a method of filtering the fluid from the grounds during operation.
- A
handle assembly 103 is used to lift the device for pouring the brewed coffee into a cup or other container. Thehandle assembly 103 may comprise ahandle 112 coupled to anupper band 113 andlower band 114. Thebands main body 101, with a ridge orabutment 107 formed on themain body 101 to seat the handle assembly and prevent movement of the handle assembly during use. Alternatively, thehandle 112 can be affixed directly to themain body 101 or may be formed as part of themain body 101 as desired. - As shown in
FIGS. 1A and 1B , the bottom member is configured such that it's threads are on the inside surface so that it mates with the outside threads of themain body 101. However, the device may be configured so that the threads on the bottom member are on the outside surface and the threads on themain body 101 are on the inside surface without departing from the scope and spirit of the device. -
FIGS. 2A-4B illustrate additional embodiments of thedevice 100 discussed above and illustrated inFIGS. 1A and 1B . The elements illustrated inFIGS. 2A-4B , which correspond to the elements described above with respect to the device illustrated inFIGS. 1A and 1B , have been designated by corresponding reference numbers increased by one hundred. Any element referenced below and identified in the attached drawings should be assumed as having the same or similar structure and function as its corresponding element shown in previous figures, except where specifically indicated otherwise below. -
FIGS. 2A and 2B illustrate another embodiment of the device that shows an insulated carafe, a different bottom member, different handle configuration and the like. It should be understood that the device may be configured with any, some, or all of these features without departing from the scope and spirit of the device. - The
device 200 implements an insulated carafe comprising amain body 201 having anouter wall 215 and aninner wall 216 with an evacuatedspace 217 there-between to provide temperature insulation. Similarly, thebottom member 202 is double walled and includes an evacuatedspace 218 to provide insulation. In one embodiment, thebottom member 202 may be single walled but made of a thermal insulating material to provide temperature insulation for the liquid contained in the device during use. - The
device 200 includes alid 204 andplunger assembly 205 withshaft 209 andplunger plate 210. As described above, theplunger plate 210 includes openings therein to allow fluid flow while inhibiting the passage of coffee grounds. Awire spring 211 encircling theplunger plate 210 provides stability during use. - A
handle 212 may be formed integrally with themain body 201. Alternatively, a handle assembly as illustrated inFIGS. 1A and 1B may be used with the embodiment ofFIGS. 2A and 2B . - The
bottom member 202 of this embodiment is coupled to themain body 201 during use by a registered pressure fit using a gasket to aid in making the seal fluid-tight. Themain body 201 has a steppedshoulder 219 that engages an opposite steppedshoulder 220 onbottom member 202. Agasket 221, which may be rubber, plastic, or some other flexible material, is placed on the upfacing step of the opposite steppedshoulder 220 of thebottom member 202. The down projecting portion of the steppedshoulder 219 ofmain body 201 engages and compresses thegasket 221 during use, providing a suitable fluid seal between the members during use. - In one embodiment, the exposed portion of the stepped
shoulder 219 is threaded, and the upper portion of the opposite steppedshoulder 220 of thebottom member 202 is also threaded for a screw on attachment mechanism, with or without thegasket 221. - In the embodiment of
FIGS. 2A and 2B , aring member 222 provides further stabilization of the plunger shaft to ensure the plunger plate remains perpendicular to theinner wall 216. - In operation, the
plunger assembly 205 is such that theplunger plate 210 descends to the approximate point of intersection between thebottom member 202 and themain body 201. After use, the spent grounds are thus captured in thebottom member 202 so that when it is decoupled from themain body 201, all of the spent grounds are found in thebottom member 202 and can be disposed of quite easily. Any spent grounds that may have seeped through the filter mechanism (i.e., the spring 211) on theplunger plate 210 can be easily rinsed away from the interior of themain body 201. -
FIGS. 3A-4B illustrate a third embodiment of aFrench Press device 300. Referring now toFIG. 3B , thedevice 300 includes a modifiedhandle assembly 303 having ahandle 312 with an elongate body that has anupper end 312 a and alower end 312 b. Thehandle 312 is affixed to theouter wall 315 of themain body 301 by anupper brace 323 proximate to theupper end 312 a and alower brace 324 proximate to thelower end 312 b. Thehandle 312 includes aninterior compartment 325 between theupper end 312 a and thelower end 312 b that houses aremovable timekeeper 326, such as a clock or an hourglass, which may be used to assist a user in measuring the time needed to brew liquid inside thedevice 300. Theinterior compartment 325 is sized and shaped to house the entirety of thetimekeeper 326 such that no portion of thetimekeeper 326 extends beyond the radial circumference of thehandle 312 when thetimekeeper 326 is inserted into theinterior compartment 325. In one embodiment, theinterior compartment 325 is accessed via a compartment opening 326 a located on the elongate body of thehandle 312 between theupper end 312 a and thelower end 312 b. - In one embodiment, the
timekeeper 326 is sized and shaped to create a friction fit within theinterior compartment 325 so that thetimekeeper 326 does not fall out of theinterior compartment 325 when thedevice 300 is in use. In one embodiment, theinterior compartment 325 includes one or more detents (not shown) that urge thetimekeeper 326 toward the inside of theinterior compartment 325. In another embodiment, thetimekeeper 326 includes one or more detents (not shown) that urge thetimekeeper 326 toward the inside of theinterior compartment 325. - Still referring to
FIG. 3B , thedevice 300 includes aplunger assembly 305 that is configured to house athermometer 327 having ahead portion 328 and astem portion 329 extending downwardly from thehead portion 328. Thethermometer 327 may be used by a user to test the temperature of the liquid to be placed inside thedevice 300 prior to brewing, and theplunger assembly 305 operates as a holster for thethermometer 327 when thethermometer 327 is not in use. - More particularly, the
plunger assembly 305 includes ahollow shaft 309 that is connected to aplunger plate 310 on the bottom end of theshaft 309 and aplunger head 330 on the opposing top end of theshaft 309. Theshaft 309 of theplunger assembly 305 is in slideable engagement with thelid 304, with theplunger plate 310 located within themain body 301 under thelid 304 and theplunger head 330 located above thelid 304. Theshaft 309 has an annularinterior surface 331 that extends upwardly through theplunger head 330 to the top end of theshaft 309 and is sized and shaped to receive thestem portion 329 of thethermometer 327. The annularinterior surface 331 has a length that is greater than or equal to the length of thestem portion 329 of thethermometer 327 so that when thethermometer 327 is inserted into theplunger assembly 305, thestem portion 329 does not make contact with theplunger plate 310 and thehead portion 328 of thethermometer 327 is able to rest on top of theplunger head 330 without exerting stress on the bottom end of thestem portion 329. - The
plunger head 330 includes ahead seat 332 that extends radially outwardly from the top of the annularinterior surface 331 of theshaft 309 to anouter head wall 333 and provides a surface on which thehead portion 328 of thethermometer 327 may rest when thethermometer 327 is inserted into theshaft 309. Theouter head wall 333 extends downwardly from thehead seat 332 to thelid 304 and upwardly from thehead seat 332 to anouter head rim 334. In one embodiment, theouter head wall 333 is sized and shaped to correspond with the perimeter of thehead portion 328 of thethermometer 327 such that when thehead portion 328 of thethermometer 327 rests on thehead seat 332, theouter head wall 333 abuts and is contiguous with the perimeter of thehead portion 328. In addition, theouter head rim 334 is positioned above thehead seat 332 by a distance approximately equal to the thickness of thehead portion 328 of thethermometer 327. This shaping of theouter head rim 334 allows for it to be flush with the top surface of thehead portion 328 of thethermometer 327 when thehead portion 328 rests upon thehead seat 332. In one embodiment, theplunger head 330 includes afinger recess 335 carved out of one side of the outer head wall that is sized and shaped to enable a user to position a finger underneath thehead portion 328 of thethermometer 327 and lift thethermometer 327 out of theplunger assembly 305. - Referring now to
FIGS. 3B, 4A, and 4B , thebottom member 302 includes a threadedsection 336 located toward the top of thebottom member 302 and areservoir section 337 located below the threadedsection 336. Thereservoir section 337 includes an annularinterior wall 338 having anupper edge 339 and alower edge 340, and abladder 341 attached to the annularinterior wall 338. The annularinterior wall 338 is sized and shaped to correspond to theinner wall 316 of themain body 301 such that when the threadedsection 336 is attached to the bottom end of themain body 301, theinner wall 316 of themain body 301 and the annularinterior wall 338 of thebottom member 302 are contiguous. - The
bladder 341 is made of a flexible, resilient, water impermeable material, such as rubber, and includes abladder floor 342 that is laterally aligned with thelower edge 340 and extends radially outwardly from the center axis of thebottom member 302 toward the annularinterior wall 338 to anannular bladder edge 343. Thebladder 341 also includes anannular bladder wall 344 that extends upwardly from theannular bladder edge 343 of thebladder floor 342 to anannular bladder seam 345, where theannular bladder wall 344 is affixed to the annularinterior wall 338 proximate to theupper edge 339. In one embodiment, thebladder floor 342 includes anannular bladder ridge 346 formed in thebladder floor 342 proximate to theannular bladder edge 343 that protrudes upwardly from thebladder floor 342 toward the top of the bottom member. Theannular bladder ridge 346 is coaxially aligned with the center axis of thebottom member 302 and provides structural support for thebladder floor 342 to maintain a flat, circular shape. - The
bladder 341 provides a flexible bottom surface for thebottom member 302 that can be compressed upwardly to ease cleaning of spent brewing solids from the bottom member after brewing.FIG. 4A shows thebladder 341 in an expanded position, whileFIG. 48 shows the bladder in a compressed position. As seen inFIG. 4A , when thebladder 341 is in an expanded position, thebladder floor 342 is positioned proximate to thelower edge 340 and the shape of theannular bladder wall 344 is flat, smooth, and substantially corresponding to the shape of the annularinterior wall 338. This is the shape thebladder 341 takes when thedevice 300 is in use. As seen inFIG. 4B , when thebladder 341 is in a compressed position, thebladder floor 342 is positioned proximate to theupper edge 339 of the annularinterior wall 338, and theannular bladder wall 344 is folded over itself. This shape taken by thebladder 341 allows for the easy removal of spent brewing solids that have collected in thereservoir section 337 of thebottom member 302. In one embodiment, thebladder floor 342 is laterally aligned with theannular bladder seam 345 when thebladder 341 is in its compressed position. - Once the
device 300 has been used and emptied of its liquid contents, spent brewing solids gather on the surface of thebladder 341. In such circumstances, as seen inFIG. 4B , thebladder floor 342 can be compressed toward the threadedsection 336 of the bottom member, causing theannular bladder wall 344 to fold over itself as thebladder floor 342 is moved upwardly. As thebladder floor 342 approaches theupper edge 339 of the annularinterior wall 338, the resiliency of thebladder 341 urges thebladder floor 342 to its compressed position, creating a launching effect that propels the spent brewing solids out of thebottom member 302. Also, the compressed position of thebladder 341 facilitates cleaning of the spent brewing solids from the bottom member, as the spent brewing solids are now closer to the threadedsection 336 of thebottom member 302 and are easier to reach and clean with a cloth or sponge. - All examples and conditional language recited herein are intended for pedagogical purposes to aid the reader in understanding the principles of the present invention and the concepts contributed by the inventor in furthering the art. As such, they are to be construed as being without limitation to such specifically recited examples and conditions. Moreover, all statements herein reciting principles, aspects, and embodiments of the invention, as well as specific examples thereof, are intended to encompass both structural and functional equivalents thereof. Additionally, it is intended that such equivalents include both currently known equivalents as well as equivalents developed in the future, i.e., any elements developed that perform the same function, regardless of structure.
- Many variations can be made to the above-described
brewing device 300 without departing from the present invention. For example, thebladder floor 342 can have a convex shape that allows spent solids to collect toward the center axis of thebottom member 302 during and after use of thebrewing device 300. Such an embodiment would have theannular bladder edge 343 be located along the annularinterior wall 338 between theupper edge 339 and thelower edge 340, thereby preventing theconvex bladder floor 342 to surpass the bottom surface of thebottom member 302. - It is to be understood that the embodiments described herein are merely exemplary and that a person skilled in the art may make many variations and modifications without departing from the spirit and scope of the invention. All such variations and modifications are intended to be included within the scope of the invention, as defined by the following claims.
