Abstract
Abstract A device (30) and method for sanitizing, with a sanitizing medium (52), a thermometer (6) having a probe (16) with a predetermined probe diameter (18). The device consists of a tube (34) having an outer surface (38) and an open end (42) adapted to receive the probe, and a closed end (46) opposite the open end and defining a reservoir (50) for holding the sanitizing medium. The device further includes a cap (60) removably attached to the tube open end and having an upper surface (64) with a central aperture (78) designed to closely receive the probe. At least one wiping member (82) in the cap is capable of forcibly gripping the probe so as to seal the sanitizing medium within the tube and to slidingly engage the probe so as to wipe the sanitizing medium from the probe when extracting the thermometer from the device.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
139 words
A system for determining the temperature of food, the system comprising: a) a food thermometer having a rigid, unbreakable probe, said probe having an outer surface and a transverse cross-sectional area; b) a tube having an outer surface, an open end adapted to receive said probe, a closed end opposite said open end, a central axis extending between said open end and said closed end, and a reservoir holding a sanitizing medium and at least a portion of said probe; and c) a cap attached to said tube adjacent said open end, said cap having: (i) an upper surface with an aperture therein sized to receive said probe; and (ii) at least one resilient member with an opening for receiving said probe, wherein said opening has a cross-sectional area no greater than the transverse cross-sectional area of said probe.
Claim 2
Independent Claim
139 words
A system for determining the temperature of food, the system comprising: a) a food thermometer having a rigid, unbreakable probe, said probe having an outer surface and a transverse cross-sectional area; b) a tube having an outer surface, an open end adapted to receive said probe, a closed end opposite said open end, a central axis extending between said open end and said closed end, and a reservoir holding a sanitizing medium and at least a portion of said probe; and c) a cap attached to said tube adjacent said open end, said cap having: (i) an upper surface with an aperture therein sized to receive said probe; and (ii) at least one resilient member with an opening for receiving said probe, wherein said opening has a cross-sectional area no greater than the transverse cross-sectional area of said probe.
Claim 3
Dependent Claim
48 words
A system according to claim 1, wherein said at least one member is configured to engage said probe with a greater force when said probe is being pulled through said opening away from said reservoir than when said probe is being inserted through said opening toward said reservoir.
Claim 4
Dependent Claim
39 words
A system according to claim 1, wherein said at least one member has an asymmetric cross section as determined relative to a plane extending normal to said central axis of said tube and intersecting said at least one member.
Claim 5
Dependent Claim
37 words
A system according to claim 2, wherein said at least one member has a radially outermost portion, a radially innermost portion and an axial thickness that decreases from said radially outermost portion to said radially innermost portion.
Claim 6
Dependent Claim
13 words
A system according to claim 1, wherein said probe is made from metal.
Claim 7
Dependent Claim
31 words
A system according to claim 1, said food thermometer having a dial attached to one end of said probe for displaying the temperature of food in which said probe is inserted.
Claim 8
Dependent Claim
69 words
A method of sanitizing the probe of a food thermometer using a sanitizing medium, comprising the steps of: a) providing the system defined in claim 1, with said reservoir being filled with a sanitizing medium; b) inserting the probe through said aperture in said cap and said opening in said at least one member into said sanitizing medium in said reservoir; and c) extracting the probe from said reservoir.
Claim 9
Dependent Claim
98 words
A method of measuring the temperature of a first food product using a food thermometer with a sanitized probe, comprising the steps of: a) providing the system defined in claim 1, with said reservoir being filled with a sanitizing medium; b) inserting the probe through said aperture in said cap and said opening in said at least one member into said sanitizing medium in said reservoir; c) extracting the probe from said reservoir thereby providing the sanitized probe; and d) inserting the sanitized probe into the first food product to measure the temperature of the first food product.
Claim 10
Dependent Claim
88 words
A method according to claim 8 for further measuring the temperature of a second food product, further comprising the steps of: a) removing the probe from the first food product; b) inserting the probe through said aperture in said cap and said opening in said at least one member into said sanitizing medium in said reservoir; c) extracting the probe from said reservoir thereby providing a re-sanitized probe; and d) inserting said re-sanitized probe into a second food product to measure the temperature of the second food product.
Claim 11
Dependent Claim
23 words
A method according to claim 9, further including the step, after said step a), of removing excess first food product from the probe.
