DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

The present invention, in some embodiments thereof, relates to the retail beverage industry and, more particularly, but not exclusively, to a tool for making a coffee beverage.

Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings. The invention is capable of other embodiments or of being practiced or carried out in various ways.

Generally, the tool described herein aims to get the same consistency in compactness/density as the manual tamping tools and/or the expensive desktop electronic tampers, is easy to use, is handheld due to a small size, is largely automated, is powered, and/or is easy to carry and move around because of its lightweight characteristics.

Referring now to the drawings, FIG. 1 is a top perspective view of a coffee tamping tool 100, in accordance with an exemplary embodiment of the invention. The tool 100, as will be described in more detail herein, is designed to consistently, automatically tamp ground coffee while being configured to be handheld (e.g. by size and by having ergonomically shaped/sloped/concave sides for grasping) and placed onto an industry standard portafilter (shown and described in more detail with respect to FIGS. 12A-B and FIGS. 13A-13E), while being wirelessly powered, in some embodiments of the invention.

FIG. 2 is a bottom perspective view of the coffee tamping tool 100, in accordance with an exemplary embodiment of the invention. The coffee tamping tool 100 includes a main body 200 which is provided with an internal compartment 202 (as shown in FIG. 4) for various operative components (such as shown and described in more detail with respect to FIGS. 10 and 11) of the tool 100 as well as a portafilter receptacle area 204 where the tool 100 is attached to a portafilter to execute a coffee tamping operation. In an embodiment of the invention, a tamper disc 206 is disposed within the receptacle area 204, the tamper disc 206 usable by the tool 100 to apply pressure to coffee grounds located in the portafilter during the tamping operation. In some embodiments of the invention, the receptacle area 204 is formed by at least one portafilter locking flap 208 which are designed/configured to interlock with the portafilter to lock the portafilter to the tool 100 during use. In some embodiments of the invention, the tamper disc 206 is replaceable and/or is interchangeable with a number of differently configured tamper discs (for example, having different diameters or thicknesses).

As can be seen in FIG. 2, the at least one locking flap 208 is shaped as a counterpart to at least one protrusion on a standard portafilter whereby twisting/rotating the portafilter in the receptacle area serves to interlock the portafilter to the tool 100 by disposing the protrusion within the locking flap 208, and likewise, twisting rotating the portafilter in the opposite direction serves to unlock the portafilter from the tool 100 (as described in more detail below). The at least one locking flap, for example, could be shaped like an inwardly facing L, where the lower portion 212 of the L-shape mechanically holds the portafilter protrusion in the locking flap 208. In some embodiments of the invention, the receptacle area 204 is provided with a sensor 210 which senses if/when a portafilter has been interlocked with the tool 100. The sensing of the portafilter by the sensor 210 activates the coffee tamping operation of the tool 100 automatically, in some embodiments of the invention. In some embodiments of the invention, the sensor 210 is a light-sensing sensor, for example a photodiode. In some embodiments of the invention, the sensor 210 is a pressure-sensing sensor, for example when the portafilter is slid into the locking flap 208, the protrusion presses on the sensor 210 to indicate its presence within the receptacle area 204.

In some embodiments of the invention, the tool 100 is configured for a wired or wireless connection to a controller device, such as a smart phone or tablet, such that operation of the tool 100 can be controlled from the controller device. For example, the tool 100 can be activated or deactivated, different modes can be selected and/or battery charging status and/or charge status can be controlled or viewed from the controller device. Optionally, the tool's 100 firmware can be updated from the controller device.

The top view of FIG. 3A shows various features for the tool 100, including a cover 302, a power switch/button 304 and two control switches/buttons 306, 308 for operating the tool 100. It should be understood that while the power switch 304 and two control switches 306, 308 are shown on the top of the tool 100, they could be located just about anywhere on the body 200 of the tool 100 and there could be no, one or more than two control switches. That is, the number and/or location of the power switch 304 and/or the two control switches 306, 308 shown in FIG. 3A are by way of example only. In some embodiments of the invention, at least one of the control switches 306, 308 is used to select one of multiple operational modes of the tool 100. Different operational modes can vary the amount of pressure applied to the coffee (in combination with at least one pressure/force sensor), the distance of travel of the tamper, the duration of applied pressure (even at different levels of distance of travel), and/or reflect pre-set performance profiles to apply differing tamping to the coffee in the portafilter depending on the wishes of the user/barista and/or the customer. In some embodiments of the invention, at least one of the switches 306, 308 uses capacitive sensing. In some embodiments of the invention, at least one of the switches 306, 308 is mechanical.

In some embodiments of the invention, the top of the tool 100 includes a display 310 for providing information to the user. For example, the display 310 can show which operational mode the tool 100 is in and/or how much distance the tamper is traveling or will travel and/or how much pressure is being applied to the coffee in the portafilter and/or the battery status of the tool 100 and/or charging status of the tool 100.
