## Abstract

A wireless rechargeable temperature probe for food, the probe having an elongate body, a proximal end portion and a distal end portion, the distal end portion having a temperature sensor therein and including a probe tip and a food-embedded portion, wherein the distal end portion includes two electrical-charging contacts electrically-isolated from one another, the electrical-charging contacts both being embedded within the food during use in order to prevent difficult cleaning.

## Claims

### Claim 1

In a wireless rechargeable temperature probe for food, the probe having an elongate body, a proximal end portion and a distal end portion, the distal end portion having a temperature sensor therein and including a probe tip and a food-embedded portion, the improvement wherein:
the probe tip is electrically-isolated from the food-embedded portion;
the food-embedded portion includes one of the electrical-charging contacts; and
the probe tip includes the other electrical charging contact.

### Claim 2 (depends on 1)

The wireless rechargeable temperature probe of claim 1 wherein the food-embedded portion of the elongate body is one of the electrical-charging contacts.

### Claim 3 (depends on 1)

The wireless rechargeable temperature probe of claim 1 further including a handle on the proximal end portion, the handle being configured to prevent rolling when placed on a horizontal flat surface.

### Claim 4 (depends on 3)

The wireless rechargeable temperature probe of claim 3 wherein the handle includes at least one flat side.

### Claim 5 (depends on 1)

The wireless rechargeable temperature probe of claim 1 wherein the elongate body has a circular cross-section.

### Claim 6

A wireless rechargeable food-temperature probe system comprising:
a probe having an elongate body, a proximal end portion and a distal end portion, the distal end portion having a temperature sensor therein and including a probe tip and a food-embedded portion, and wherein
the probe tip is electrically-isolated from the food-embedded portion,
the food-embedded portion includes one of the electrical-charging contacts, and
the probe tip includes the other electrical charging contact; and
an electrically-powered probe charger configured to mate with and charge the probe.

### Claim 7 (depends on 6)

The wireless rechargeable food-temperature probe system of claim 6 wherein the food-embedded portion of the elongate body is one of the electrical-charging contacts.

### Claim 8 (depends on 6)

The wireless rechargeable food-temperature probe system of claim 6 further including a handle on the proximal end portion, the handle being configured to prevent rolling when placed on a horizontal flat surface.

### Claim 9 (depends on 8)

The wireless rechargeable food-temperature probe system of claim 8 wherein the handle includes at least one flat side.

### Claim 10 (depends on 6)

The wireless rechargeable food-temperature probe system of claim 6 wherein the elongate body has a circular cross-section.

### Claim 11 (depends on 6)

The wireless rechargeable food-temperature probe system of claim 6 wherein the electrically-powered probe charger further includes a battery to charge the probe.

### Claim 12 (depends on 11)

The wireless rechargeable food-temperature probe system of claim 11 wherein the food-embedded portion of the elongate body is one of the electrical-charging contacts.

### Claim 13 (depends on 11)

The wireless rechargeable food-temperature probe system of claim 11 further including a handle on the proximal end portion, the handle being configured to prevent rolling when placed on a horizontal flat surface.

### Claim 14 (depends on 13)

The wireless rechargeable food-temperature probe system of claim 13 wherein the handle includes at least one flat side.

### Claim 15 (depends on 11)

The wireless rechargeable food-temperature probe system of claim 11 wherein the elongate body has a circular cross-section.
