Abstract
Abstract A probe suitable for monitoring temperature and pressure in a relatively thin-walled container fabricated from plastic. The internal probe monitors the pressure and temperature at substantially the geometric center of a container in a pasteurizing or sterilizing apparatus. The probe is provided with a sharp container-wall piercing end and a tapered threaded self tapping portion which provides an effective seal. The probe is hollow so that fluid can be conducted from the interior of the container and its pressure determined. A temperature sensing member is carried within the hollow probe so that temperature within the container may be sensed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
151 words
A probe adapted to be inserted into a closed thin plastic container for monitoring pressure and temperature therein, the probe comprising temperature sensing means; a hollow member having a forward piercing open end and a rearward open end defining a bore therethrough to provide open space for passage of fluid from within the thin plastic container whereby fluid pressure therein may be monitored, an intermediate portion of said hollow member between said piercing open end and said rearward open end being tapered, the taper thereof converging toward said piercing open end; self tapping threads provided on an exterior surface of the tapered intermediate portion of said hollow member to spread and tap through the closed thin plastic container; the temperature sensing means supported by means within the hollow member for sensing temperature within the thin plastic container; and means within said bore for allowing electrical communication with said temperature sensing means.
Claim 2
Dependent Claim
151 words
A probe adapted to be inserted into a closed thin plastic container for monitoring pressure and temperature therein, the probe comprising temperature sensing means; a hollow member having a forward piercing open end and a rearward open end defining a bore therethrough to provide open space for passage of fluid from within the thin plastic container whereby fluid pressure therein may be monitored, an intermediate portion of said hollow member between said piercing open end and said rearward open end being tapered, the taper thereof converging toward said piercing open end; self tapping threads provided on an exterior surface of the tapered intermediate portion of said hollow member to spread and tap through the closed thin plastic container; the temperature sensing means supported by means within the hollow member for sensing temperature within the thin plastic container; and means within said bore for allowing electrical communication with said temperature sensing means.
Claim 3
Dependent Claim
38 words
